How to make a concrete mixer from the barrel. Concrete mixer with her own hands: We make a compulsory concrete mixer, having studied the drawings. Driver mechanical concrete mixer

Get a concrete mixture for home use now is not a problem - it is enough for the sale of relatively inexpensive household models. Nuance: similar products do not differ in the capacity (only 60 ... 100 liters) and reliability, because they are made of cheap components. The domotist host, which owns the skills of fitter and welding works, is easier to make a concrete mixer of the desired volume with his own hands, following our recommendations.

Selection of agitator design

For and prepare cement solutions of various stamps, the following types of mechanized mixers are used:

Forced action - screw and blade;
gravitational;
vibration.

Concrete mixer forced (left) and gravitational action (right)

Note. Mixers for a solution of vibration type are used on an industrial scale. Collect the handicraft option at home is also real - for example, from a manual puncher. But seriously consider such homemakes should not be, the reason is the small performance of the installation.

Usually, homemade craftsmen make gravitational and forced models of concrete mixers - it is easier to gain components and materials available in the farm. We will analyze each design.

Forced action mixers

The principle of operation of this construction machine resembles the preparation of a solution of a drill with a nozzle - a mixer. Stirring occurs with the help of blades or a screw installed inside the fixed cylindrical container. Drive - gear, chain or belt from an electric motor with a power of 500 W and more (depends on the size of the container).

The principle of forced mixing - the case remains fixed, only the blades rotate

The designs of forced concrete mixers may differ in a number of signs:

The position of the baud - vertical or horizontal;
Mobility - stationary installations (moving by a crane or wolf) or mobile models on wheels;
The method of unloading - through the opening hatch or turning the horizontal baud, fixed on the hinges;
The order of work is cyclic or continuous.

Reference. Household mixers are designed for cyclic operation - loading ingredients - mixing - unloading, then the cycle is repeated. The screw mixers can function continuously - on the one hand, dry components are covered, on the other, it turns out the finished solution. An example of such a machine is shown in the drawing.

The main advantage of forced concrete mixer is to obtain a homogeneous high-quality solution. Disadvantages:

The complexity of manufacture - the housing and the work part must be clearly adjusted to each other so that there are no dead zones in the corners of the container, where the blades do not get;
The preparation of concrete is hampered - large and medium-sized pebbles are stuck between the walls of the baud and blades;
Homemade stirrer bearings need to be protected from water penetration, sand and cement.

Conclusion: The installation is perfect for the implementation of plastering, finishing and masonry, especially with the use of dry mixtures. It is also permissible to prepare concrete with a filler of a small fraction - gravel, marble crumb and so on.

Gravitational type machines

The simplest manual concrete mixer using the principle of natural mixing is shown in the photo. If the household is removed the iron barrel 200 l and trimming the metal, such a homemade design will cost almost free - only bearings will have to buy from the parts.

Council. The machine with a manual drive is best made from the barrel installed on the diagonal axis. Tested by practice: the quality of the preparation of dry building mixtures and concrete is significantly improved, and the pipe passing through tube serves as an additional divider of the solution.

A classic concrete mixer with pear-like baud uses a combined forcibly gravitational principle. From within the tank, the blades of the cunning blade are welded, passing the concrete mixture along the walls, but the exciting solution closer to the center. The "pear" rotates the electric motor, the concrete is unloaded by inclination of the worker drum.

What are the good designs:

The mixer is suitable for the preparation of any solutions;
Ease of manufacture - hinged elements are made beyond the capacity and do not need to be sealing;
"Pear" and the drive can be placed on a stationary or mobile frame, equipped with wheels and even a trailer device for a passenger car.

Traditional concrete mixers are inferior to forced in the speed of preparation and homogeneity of the solution, but won in the simplicity of design and versatility. For domestic use, the gravitational models are more suitable. An example of such a homemade with a motor from a washing machine is shown in the video:

Make a solid cheer

To find parts for assembling the construction machine, we suggest examining its device according to the presented drawing (the list items coincide with the positions on the sketch):

The mixing drum made of metallic 200-liter barrel.
Handling knurpeting "pears" - steel pipe Ø20-26 mm.
Drum support rollers - 2 pcs.
Frame made of metal profile pipe with a cross section of 50 x 30 mm, the thickness of the wall is 2.5 mm.
Electric motor 750 ... 2000 rpm, with a capacity of 0.5 ... 1.5 kW.
Supporting swivel subframe.
Artistic Cross - Metal strip 40 x 3 mm.
Intermediate pulley.
Pulley main.

Note. Dimensions and methods of connecting parts can be changed depending on the circumferential materials.

As the supporting rollers, craftsmen use small wheels or ordinary rolling bearings. Instead of the profile pipe without problems, a round or corner plus chastellers is used. The dimensions of intermediate and driving pulleys are selected depending on the number of electric motor turns.

In addition to the specified materials, you will need a power cable, a block of starting capacitors and an enable / stop button.

Manufacturing bacha

The strict cylindrical shape of the barrel does not contribute to the high-quality mixing of cement with ingredients - rubble, sand, claymzit and other fillers. After the positiveness of the water, one part of the mass sticks to the bottom, the other splashes through the neck.

Before collecting a concrete mixer, you need to make a "pear" from the barrel:

Note. The longer you will make vertical cuts, the more the narrowing of the "pears". But remember - too long "petals" bend unevenly, as a result, the container will lose the right form, during rotation there will be axial beating.

To the lower end of the baud, you need to re-fight the bottom and crossbar under the articulation of the drive. Another option is to fasten the bearing clip.

Frame assembly and drive device

The design of the iron frame - arbitrary, depends on the dimensions of the drum, the method of installation and the submitted materials found. When assembling, consider the following recommendations:

The frame should be stable, withstand swaying and tipping a barrel with concrete;
between vertical racks and horizontal elements weld the ribs of stiffness;
the inner swivel frame is better to do on bearings, although it is quite acceptable to use hinges on the sleeves;
Under the engine and drive parts, prepare the fasteners;
If the torque is transmitted by the belt, refer to the sliding mount of the motor or pulley for its tension / weakening;
Put the retainer to fix the baud in the inclined position - the metal rod, inserted into the holes on the rotary part, will be used.

Special attention is paid to the calculation of the drive mechanism. The optimal speed of rotation of the "pear" is 30 ... 40 rpm, exceeding or underestimated the indicated revs are not recommended. The task is to choose to the existing electric motor of the pulleys, gears or gearbox, in order to lower the speed. We calculate the gear ratio i, then determine the dimensions of the pulleys using the equation:

I \u003d n1 / n2 \u003d d1 / d2

n1, N2 is the speed of the lead and driven pulley, respectively;
D1, D2 - Pulleys diameters.

Example of calculation. There is an engine with turnover of a shaft 800 rpm, the size of the drive wheel is 60 mm. In order to obtain the speed of rotation of the baud 40 rpm, it is necessary to select a slave pulley with a diameter d2 \u003d (800 x 60) / 40 \u003d 1200 mm. When using a chain and gear transmission, you need to consider the teeth of stars.

Typically, the size of the slave gear is too large. In the manufacture of concrete mixers with their own hands, the torque from the electric motor can be transferred to the drum in different ways:

Reference. On the factory models, the question is solved in a similar way - the driven gear is climbing directly into the corps of the baud.

After assembling the frame and installation of support rollers, the barrel is finally attached to the bottom hub. It remains to connect the wired mechanism and collect the power stirrer power circuit.

Conclusion

For the needs of a private household, a concrete mixer is quite a useful volume of 0.15 cube, which just corresponds to a 200-liter barrel. A homemade installation can always be improved - to attach the wheels, towing device and even organize a soft-loading using a small conveyor. Options for modernization of construction equipment often publish participants of thematic forums.

Designer engineer with experience in construction for more than 8 years ..
He graduated from the Eastern Ukrainian National University. Vladimir Dalya in the specialty "Equipment of the Electronic Industry" in 2011.

For the improvement of the site often needed a solution, then concrete. There is no time to knead it - heavily and long, and the quality of the solution is far from the best: it is difficult to achieve homogeneity. Not everyone wants to buy a concrete mixer for her periodic use. Good output - concrete mixer with your own hands. There is a little money, on performance, self-made units are not worse than Chinese, but sometimes better.

Manual concrete mixer

There is no electricity on the construction site, and large volumes of solution and concrete are not always required. Exit - make a concrete mixture of a small volume that will rotate manually (with a manual drive). The designs of these models are simple and uncomplicated.

From dairy flask

The simple manual concrete mixer can be made by the usual metal flask (earlier they sold in such milk). We still need trimming pipes or other scrap metal. The design is simple, such a concrete mixer is implemented in a couple of hours. The main thing is to weld the frame. The assembly of the concrete mixer itself will take a couple of tens of minutes.

We make the bed, out of the round tube, fuse the handle. At the top of the bed, weld two water clutches (for example). Their inner diameter is slightly larger than the diameter of the pipe used for the handle. The pipe is passed through the flask, weld to the case.

So that the barrel spinning easily, it is necessary to find the center of gravity. To do this, it can be put on some subtle item, and moving forward / backward, find this very center. That's through it and you will need to skip the handle. By skipping the handle, it is fixed to the walls of the housing. Difficulties may arise: the flasks are usually made from an aluminum alloy, and the handle can be made of steel. Connect from using welding will not be possible. The only available output is cold welding. He is quite real. The remaining modes - with bimetallic gaskets or argon-disposable welding at home are not implemented. Another way out is to weld the plates on the handle that stick to the sides of the flasks.

So that the handle is not very pitted and not falling out when working, nuts weld to it from both sides of the coupling.

In general, this is all the manufacture of manual concrete mixer with your own hands. For one, 2.5-3 buckets of the solution can be obtained in one-liter bidon. For use in the country or on a plot near the house (without a construction site) more than enough.

If there is no bidon, you can adjust the barrel (thick-walled). Then the problem with the welding handle disappears, but you have to come up with a lid fixation system. You can make something similar to the one that is available at the bidon.

In the video - an example of a handmade self-made concrete mixer made of dairy flask. The design is a bit different, but not too different. There is an interesting idea - dividers are welded inside the tank, which accelerate mixing.

From barrel (manual and with electric drive)

This design called the "Drunk Barrel" - due to a peculiar trajectory of movement. The whole point is that the axis of rotation goes through the container of the necchock. Due to which the solution rolls over from one wall to another. The design is also simple and effective. What is important - there are no problems with welding heterogeneous metals. Drawing of manual concrete mixer from the barrel is shown below.

In the upper part of the frame in the center, bearings are installed in which the handle has grown. Thanks to them spinning 200 liter barrel easily. Just choose a container with thick walls - last longer. Inside, no additional blades do not weld: they only delay the components, mixing stirring and complicate the unloading.

In the original design, the loading / unloading hatch is in the bottom. This is a cut part (approximately 1/3), attached with the hinge to the bottom, equipped with a sealing rubber around the perimeter and closing into two locks. When loading, the barrel turn so that the hatch is at the top. When unloading - rotate down. The solution of gravity moves into the substituted container, and the sticking can be removed by knocking on the housing with a hammer or sledge hammer.

This design served in the author 10 years, although it was done for one-time work, but it turned out to be very successful: 2.5 buckets of the solution are well mixed in 20-30 revolutions. During this time, her neighbors and acquaintances were repeated and improved. Mostly alterations concerned Luke. The most successful design is identified experimentally - similar to the one that is used in the dairy flask. Such a "neck" is welded to the body of a barrel with one of the sides (see photo at the top). Also make handles on both sides - for the possibility of working together.

This design is easily converted into an electrical homemade concrete mixer. A not very powerful engine is set - 1 kW for a barrel of 200 liters is enough, to the axis of which a small asterisk is attached to the axis of the pipe larger (to reduce the number of revolutions), they are connected using a chain (from a scooter, for example).

Electro-concrete mixer with her hands from barrel and engine washing machine

This concrete mixer is reduced type. For the manufacture of this model needed:

barrel made of galvanized steel by 180 liters (diameter 560 mm, height - 720 mm);
engine washing machine - 180 W, 1450 rpm;
flywheel and starter gear from Muscovite 412;
two pulleys from a washing machine with a diameter of 300 mm and 60 mm;
wheels from a garden trolley;
scrap metal for frame.

Gears, wheels - all old, everything was in the garage

First of all, we all clean up from rust, process the rust converter and coated with soil.

Cook frame from pipes, channel. Rama angles enhance the welding of the metal plate. Everything should be tough and reliable. The crossbar do serious: it will "hang" a barrel with a solution on it, and everything will still vibrate and spin.

Frame - base of construction. Pipes are almost new))

We weld the pins, landing space under the gear gear. We clean from rust, process the rust converter, soil.

Fresh wheel from the trolley. They with wide treads and justified themselves: to drag the concrete mixer is simple, even just in the site.

From the pipes can be more constructions for stopping and installing the entire "filling".

Second - for greater stability

We start collecting the drive. First put a big gear on the previously welded pin.

In the landing site, we set the assembly - a small gear connected to the wheel for belt transmission.

To the welded plates of the plates are securely.

It is suspended so that two wheels of the belt transmission are on the same level. It is also necessary to ensure normal belt tension.

It remains to attach a barrel. In the center we make a hole under the big pulley, drill a hole for fasteners. Put in place.

It remains only the electrical part. Connect the cable through

Multiple photos of the main nodes. Maybe someone needs to look closer.

The second transmission option - from a car disk

The barrel is 200-liter, her edges were cut, bent and welded, forming the familiar "pear".

From the barrels made a "pear"

The car disk attached bolts to the bottom (with rubber gaskets). It was selected so that the removal for the belt transmission was formed. The disk had previously attached the hub.

Inside the barrel welded blades for more efficient mixing of the solution.

All this farm attached to the frame.

Where the plate is welded - a place for the engine. I exhibit it so that the belt goes smoothly. Power filed through the toggle switch, the timer is sequentially included from the washing machine with which the motor was removed.

In general, the speed of rotation turned out to be 35-40 revolutions per minute. It should be enough.

Homemade stirrers in the video version

If the general principle is clear how the concrete mixer is done with their own hands, you can upgrade it and redo it, adjusting to the available parts. Assist in this video collected in this section.

Crown type

Another option, only no longer, and a crown type. The crown, by the way, can be bought (cast iron or plastic) and install on the barrel.

With rollers as a support

Collable barrel mixer

Photo of homemade concrete mixers (may be useful)

Each or almost every concrete mixer made with their own hands has some original solutions. Few people repeats the design completely, without making any changes - you have to adapt to those details and nodes that are in stock. Some interesting solutions are in the photo.

Organization of transmission using a motor-chain and a second - belt

The shape of the blades is a complicated thing. It is necessary that they improve mixing, and did not delay concrete from falling down

With a limited budget, buy equipment that will only be needed for one construction, unprofitable. If the firms offering the rental tools have not yet opened next door, the concrete mixer made with their own hands will save a great way! If you go to a homemade device with care, it will last not one year.

Types of concrete mixers

After examining the mechanism of work of concrete mixers and their characteristics, it will be possible to choose a design suitable for the needs of specific construction. After all, why complicate your work if you manage to do with a simple mechanical device?

On the other hand, loading the concrete mixer under the urban, finish the fill of the foundation will not be able to quickly - this will lead to a banal engine overload and its imminent failure.

Mechanical or electric?

Choosing the design of the future "Assistant", should immediately decide on how to work it:

mechanical concrete mixers - work from a manual drive, when a large amount of concrete, turn the gate to twist together;
electric concrete mixers - work from the network, but the connection of the motor requires good knowledge of auto mechanics.

If several strong and hardy people are involved at the construction site, you can do the handmade concrete mixture. The ingredients of the mixture are loaded or simultaneously, or alternately. The only inconvenience is a design with a movable barrel, and not an internal shaft, do not allow to add water during the mixing process. The barrel must be stopped, opening the hatch and pour water. The hatch closes and the mixture is prevented again.

Electric concrete mixers allow you to knead large volumes of concrete for the shortest possible time, one person copes with the work. It should be borne in mind that high-power motors require a three-phase network, so when choosing a tank volume, you should calculate the power of the motor in advance. If only a line of 220 V is connected to the court, he will have to forget about heavy solutions.

Forced, gravitational or vibratory?

The principle of work of concrete mixer will depend on its design:

concrete mixers of forced action are distinguished by a fixed capacity, in which the blades attached to the shaft rotate;
gravitational concrete mixers are stirred by concrete due to the rotation of the actual capacity in which the blades are rigidly fixed on the walls;
vibrating concrete mixers cannot boast of great performance, but provide high-quality and homogeneous mixture without bubbles.

At the same time, gravitational, and the forced action of concrete mixers can be both mechanical and electrical. The whole difference is that the mechanical concrete mixer of forced action has a horizontal axis, and the electric can have both vertical.

For their manufacture, you will need a metal container. The most elementary option is a metal barrel with a thickness of 2.5 mm thick.

Vibrating homemade concrete mixers are available to each perforator owner. And although it is not possible to pour the foundation with their help, make the filler floor in the bathroom or interface the tile solution is quite real. At the same time, the design is nowhere else and does not require direct human participation. So even a woman will cope with work.

Volume of concrete mixer

An important criterion for choice is the capacity of future concrete mixer. For example, for work on the fill of the foundation, a capacity of 200 liters is required for a minimum. It should be borne in mind that the finished mixture will be 15-25% less - depending on the boot capabilities.

Manually, this volume of concrete can be kneaded, although it is hard enough - the hand will be tired.

A self-made device has another significant disadvantage - the reset of the mixture is often produced in full. Therefore, it is better to take care of a wheelbarrow in advance. If there is an opportunity to make a partial reset mechanism - it is better not to regret the time to create it. This will significantly simplify the operation of spacious electrical concrete mixers and will allow working together by loading two cars.

Drawings and device of simple concrete mixers

If the volume of construction is small, you can do with simple concrete mixers, the creation of which will not require serious labor and cash costs.

Vibration concrete mixer from perforator

The presence of a mixer nozzle is required for any construction work. But to keep the drill while she kneads the solution in the bucket, it is hard and time is lost in vain. If there is a perforator with manual inclusion of the impact mechanism, you can quickly make a vibratory concrete mixer:

The perforator will be required with a capacity of 1-1.3 kW. Less powerful will be ineffective.
The vibrator is manufactured - the main acting part of the concrete mixer. Incorrectly made vibrator simply disappoints concrete. Its shape must resemble a biconimous lens - flat edges and a convex middle. For example, it can be folded together and fixed metal plates. The disk diameter is calculated on the basis of 20 cm per 1 kW. For a perforator of 1,3 kW, a vibrator with a diameter of 25 cm will be needed.
Round capacity seabed. The distance from its walls to the vibrator should be equal to its radius. So, for a vibrator with a diameter of 25 cm, a tank with a diameter of 50 cm is needed.
A perforator bracket is installed. The position of the vibrator is calculated so that its distance to the bottom is to be diameter, in this example it is 25 cm. The amount of solution above the vibrator should be the same.

The readiness of the solution during the operation of such a concrete mixer is determined by the absence of rising bubbles and the formation of small waves on the surface. If the cement or sand is low-quality, the solution may not form the waves. Then the mixture is ready when it stops moving and bung out.

Concrete mixer with manual barrel

You will need a two-shifted metal barrel, a metal pipe with a diameter of 2-3 cm, flanges, Bulgarian and welding machine:

The boot hole and two opposite holes for the pipe cut down in the barrel, which will be axis. The axis can be traded both through the center of the barrel and diagonally. In the second case, the mixture will be mixed better.

From the inside the barrels to the walls are welded 2-3 blades - so that the mixture does not stick to the walls and is better mixed. The blades should pass along the entire barrel, but do not fit close to the walls - otherwise the solution will constantly accumulate in the seams.

The pipe is done, its ends are welded and fixed with flanges.
It is manufactured for a concrete mixer. Its height should be such that it was convenient to load the ingredients of the mixture, without lifting them too high, but also to interfere with it did not have to bother, bent into three deaths. On the supports under the axis, it is necessary to make ride, which will allow the axis to spin freely. You can use both the hollow tube of larger diameter and bearings.

It is necessary to provide a wide, durable and sustainable base that binds the legs of the supports. This will prevent the concrete mixer tenting during the work.
Levers are welded to the axis. Do not forget that they should be easily opposite to each other. The longer the lever - the easier it is to move the barrel. But too long lever is not convenient in work, so you should hold onto the golden middle.

The lid of the loading hatch must close tightly - so that the mixture does not flow. You can cut the lid of the larger size from the same barrel and the perimeter can be cleared with dense rubber. And you can use a part from the same barrel left from cutting the boot hole. To do this, it is necessary to simply weld along the edge of the centimeter metal strip and also compact its rubber.

Similar design and outdoor concrete mixer. Only instead of the movable barrel inside the blades are spinning, which are also powered by human efforts. For its manufacture, you will need a barrel actually, and the pipes of the round and rectangular cross section. The barrel stacked on the side, the top is cut off from it. It is better to leave as much barrel as possible - to be able to knead more concrete.

Over the sides cut holes for the shaft. But, unlike gravitational concrete mixtures, the blades are welded to the tree itself. You can use any details, even the blade from the combine!

The mixture is also unloaded by the coup of the entire barrel.

Such concrete mixers are a very budget option, but requires the constant participation of two employees. If you have to work alone, you will need a device with an electric motor. For example, an open type variant can be quickly improved by connecting the engine to it.

Electric drive "factory" concrete mixers

Without possessing confident skills of the welder, it is better not to try to repeat the factory models of concrete mixers. But in the presence of an experienced neighbor, you can make excellent techniques from almost nothing! At the same time, such a concrete mixer will serve more than 10 years, helping the construction of the entire country village.

Homemade gravitational concrete mixer made of scrap metal

After that, you will have to ride on redemption points of redemption and authoring plants in search of the necessary details:

metal sheets with a thickness of 2.5 mm for walls and 5 mm for a pear bottom;
flywheel from the car, for example, from "Volga" or Maz, hub and bendix - for the mechanism of pear rotation;
bearings for overturning pear (you can do the "pipe to the pipe" system, richly lubricating the pouring);
metal pipes of square section and different diameter - for the base, planting place and rotary wheel.

When all materials are collected, you can proceed directly to the manufacture of concrete mixers:

Figure and welded elements of the case. Bending steel can be a sledgehammer, even if individual parts are not perfectly smooth, when welding together, they will take the right form.

While the pear is not welded together, to the lower part of it, carved from 5 millimeter steel, the mechanism of rotation is attached. It is advisable to make it removable - to transport collapsible concrete mixer easier.

Weld together parts of pear. First, the central and lower parts are combined. For this edge of the central rim, they are cut and bend inside - to limit the output of the lower part. Through the top of the central rim, the bottom item is inserted and the sledgehammer is added to the face down until it stops down. When the edges are aligned, they can be welded.

The upper part of the pear is descended into the central, the edges of the central rim also cut and bend inward. With the help of a nail, the top "is flushed" until the stop is also welded.
From the inside of pears, blades that promote mixing mixture are welded. In order for the solution to do not accumulate in the seams, the blades are attached at a short distance from the walls.
You can start making a seating area that ensures pear tipping. Given the large weight even empty capacity, you need to take care of the high reliability and strength of the frame.

The tipping mechanism must be made on the flywheel with a gear - so tipping the complete container will be even one. You can cook the hex wheel or admit any other.

A gearbox is manufactured, which will transmit torque from the engine to the pear. Pulleys on the shaft and the engine are calculated so that up to 25 pear revolutions per minute.

So that the major parts of the mixture do not fall into the rotation mechanism, you can screw the strip over the crown, but this stage is optional.

In principle, the concrete mixer is ready. Optionally, it can be painted - to protect the metal from corrosion, although during operation it will still acquire a classic gray color.

Concrete mixer forced type made of tin pans

If it is not, you can order a saucepan with a diameter of 60 cm and a depth of 50 cm at a familiar tinsmith. After that, it remains only to adjust the mechanism, blades and make a hatch:

Placed the center of the tank - it is there that will be the shaft. The hatch is cut out for unloading the mixture. Rectangular cut easier, but then the whole mixture is broken into the wheelbarrow. It is better to make a swivel semicircular hatch.

For this, the core is welded in the center of the cut-off semicircle, on which the hatch will turn. So that the mixture does not flow over, the strip is welded over the cutout of the hatch, under which the curtain will move.

In an inverted state, an engine with a gearbox is attached to the installed bearing. To securely fix the engine and ensure the desired belt tension, the engine is installed on the racks welded to the bottom.

To enhance the frame of the tank made of steel, 2 mm thick on the upper edge necessarily welded rim from the steel rod or pipe. You can also make the ribs of stiffness on the sides and below the tank.

After the wheels, support and rotation mechanism are installed, the entire design can be turned over. The blades are attached to the shaft and everything is fixed by one bolt - so that the design is easily collapsible. It is important to correctly think over the position of the blades - one should remove the solution from the walls, the second separating it from the bottom, and a few more - mix the middle.

You can do the design of scrap and crosses from the plumbing flange. If the blades are movable, their position can be adjusted depending on the type of mixture.

Concrete mixer forced action is ready! It can be interfered with almost any mixtures, make them liquid or dense, add rubble large and fine fractions. The same concrete mixer, but horizontal type, can be done, guided by the drawing.

Vitely the process of assembling concrete mixers made of steel barrels is presented in video:

This is one of the simplest ways to make a reasonable construction technique with a minimum cost!

When performing heavy construction work, a manual concrete mixer will become an indispensable and in demand by the assistant. The possibilities of this useful device are not limited to concrete itself, with no less success in it you can knead any cement-sandy solution.

Concrete mixer - for and against

Determine the scope of applying the concrete mixer of its own manufacture is quite easy. It should be proceeded from personal ability to severe construction work. Because to knead the solution in a mechanized 200-liter barrel can be relatively easy, but this cement-gravel mixture still needs to be delivered to the destination, pour into the form and subjected to vibrating seal (if such is provided by technology). Nearby per day, the solution will freeze the shapeless chest, as a monument to your mismanagement.

Another extreme is to attempt to concrete the foundation of 10x20 meters with a self-made solution. No concrete mixer of such volumes of work is asset, and its owner and suppressed. It is wiser to order a concrete dump truck with a volume of several cubes and scatter its contents on the advanced formwork - it will be optimally both on financial and physical expenditures.

Masters of the site site prepared a special calculator for you. You can easily calculate the desired amount of concrete.

Therefore, personal concrete mixer is used for such work as the construction of the porch with their own hands, creating a screed in one room or when installing piles for a fence. The volume of concreting should correspond to your physical capabilities and hardware containers of the device itself.

Concrete mixer - electric or mechanical?

In fact, there is no big difference in the complexity of the manufacture between the electrical and mechanical concrete mixer. Another thing is that the complexity of the electrical version is significantly higher, but they can be used alone. The manual option is necessarily associated with the work together, it is necessary to "turn the drum" to someone, as the permanent leading lead in one famous show says.

But! Mechanical manual concrete mixer can be made mobile, that is, mobile. The electrical option is difficult to pour into the wheels and carry on the preservation area - it is complicated, bulky and needs more durable frame and chassis. Vibration from the electric motor is also very high. If necessary, electric mobile concrete mixer is better to buy in the store, how to strive for the laurels of the Great Designer. A similar desire can end the cliff of the drive belt (at best) or the voltage breakdown on the metal case (and from such a confusion the consequences are the most deplorable).

Manual concrete mixer - do it yourself make a mechanical assistant

The sequence of making a handicraft device for the kneading solution consists of several stages:

Handmade concrete mixer with their own hands - step-by-step scheme

Step 1: Calculated

It is not connected with work on the apparatus, but with an assessment of the metallic Skarba existing in the farm. Before the drawings we will get a little later. The basis of any concrete mixer is a bulk metal container. The barrel for 150-250 liters is suitable for this best, it is possible. If the desired barrel is not detected in the farm, you can search something similar to neighbors or acquaintances. You can captivate their prospect to forget about the manual substitution of concrete and take the barrel interactive, with the condition of the subsequent rental of concrete mixers. Yes, for our barrel, you definitely need a "native" cover, which is welded to the landing place.

In addition, it will be necessary with the help of a welding rectifier or inverter to make a carrier frame. For this, you will need pipes or corners of ferrous metal (from the reinforcement the frame will be heavy) and the welding machine itself. It is quite reasonable - modern models are inexpensive, work from domestic 220 volts, are mastered relatively easily and significantly make it easier for economic weekdays in the Nature.

Step 2: Marking and verification

We place the frame circuits, based on the dimensions of the barrel - it will be the center of our man-made composition. If the frame base is corners, then the size of their shelves should be at least 50x50 mm. If the pipes are well suited by ordinary water supply, 25 mm of external diameter (again can be used, just not rusty). The armature for the frame and handles is needed with a diameter of at least 15 mm, preferably corrugated. For the shaft, the thick and smooth armature of large diameter, not less than 40 mm, is needed.

We experience a barrel for tightness and strength. It is necessary to catch her walls and find out whether there is no rusty plots. If they are discovered, they will need to boil the sheet metal outside and check the tightness again. We flatter two bearings, two door loops, check the performance of the welding machine and the grinder.

Step 3: Welding

In the geometric center of the bottom of the barrels, a hole is done under the shaft. The same hole is drilled in the lid (it is not yet welded!). A flange with a shaft is welded into the center of the bottom, the bearing is sisted on it. With a lid it will be more difficult - a movable flange with blades is welded to it, which will stir the solution during the rotation of the handle.

The blades will need no less than three, their dimensions must be taken to the middle of the barrel, but do not scribe along its walls. That is, we show the skill of artistic welding and create an inner iron flower - a flywheel of the concrete mixing process. Side frame racks are welded in the form of the letter A, their size is identical. If the concrete mixer is self-devil, then the side racks are welded to each other with long reinforcement twists, and metal wheels are attached to the ends of the legs - wide and durable.

The bottom is placed on the shaft of the bearing, the lid with the blades is inserted onto the seat and weld around the perimeter. The second support with the handle is swinging and is also installed on the bearing - the main part of the work is completed.

Step 4: Finishing

In the side of the barrel, the hole is cut down at least 30x30 cm to load the components of the solution and unloading the finished concrete. Work is performed using a grinder, and carefully - it is impossible to damage the bulk of the wall. The carved part is planted on two loops, with the sealing of bolted bolts resistant to cement with compositions (silicone sealant, etc.). What will already be the cutting disc of the Bulgarian - the better it will provide a dense pairing of a man-made hatch and walls. Therefore, the final part of the slits is performed by acute hacksaw for metal.

To the side of the barrel, where the blades are located, a long and durable handle is welded. For the kneading standard concrete, it is enough to load through the sand, gravel, cement and water door, it is good to close it, check the handle on 15-20 full revolutions and can be stored a wheelbarrow to unload the finished solution.

Manual concrete mixer with their own hands made! Pour into it the water "under the string" to check the tightness and can knead the trial batch of the solution. When the own stages of heavy construction will remain in the past, your mechanical assistant will become a popular guest in neighbors who are only the fundamental work.

Can you imagine a construction site on which there is no little concrete mixer? Without such an aggregate, the preparation of a good cement mortar becomes almost impossible. When it becomes necessary to build a small construction or just something to "patch", concreting becomes a popular task. Here is just a short list of situations in which it is not necessary without this tool: the fill of the garden tracks, the construction of the foundation for the arbor, the installation of the fence and so on. In short, concrete is needed everywhere - the difference is only on the scale of the event. For household needs to buy an industrial device meaninglessly - the purchase will cost you exorbitantly expensive. An alternative solution will be homemade concrete mixer with their own hands. Thanks to this article, you will learn how to do it yourself from the girlfriend.

Four mixing principles of concrete

Homemade concrete mixer

According to facts, it is possible to prepare your solution without special devices. It even likes to work on the old technique. But do you manage to do so much in this way? Create a dry mix for construction using a conventional drill or a mixer, you can still. But when it comes to sand with cement, they turn out to be powerless.

The easiest and most common principle of mixing is called forced. All components are kneaded in the container, which is fixed. For this purpose, a mechanical drive is usually used. The working drum can be located vertically or horizontally.

Despite the fact that even a small concrete mixer of forced action may be very effective, he also has its drawbacks:

"Dead zones" appear in the container. This is especially true of space near the walls.
The complexity of the design. Nodes of rotation should be hermetically protected from the impact of a solution that can be aggressive.
It is almost impossible to prepare a solution in such an unit, which consists of medium and large filler.

The second principle is called gravitational. In this case, all components are mixed due to the power of gravity. In industry, this method is rarely used, as it takes a lot of time and effort. As containers, most often go into the course of barrels that are made of metal. About how they are manufactured, how to make a stand, will be described below.

Most modern concrete mixers use a combined principle that combines the first two ways. They possess the following advantages:

Strict sealing is not needed. The drum on top is open, there is no need for nodes of rotation, since any contact with the solution is excluded.
Details wears much less often.
Easy and reliability of operation.
There are no restrictions on the composition of the solution - it may be rubbank, ceramzit, gravel, and so on.

The fourth mixing principle is called vibration. Recently, some craftsmen are engaged in mixing the solution with vibration. If we talk about large-scale volumes, the results can be the most stunning. Usually, the vibration principle of stirring is used when you need to make an accurate reinforced concrete design with good performance characteristics.

Under normal conditions, the gearbox and the drive replaces the most powerful perforator (permissible minimum of 1.3 kW). Its vibration action should be independent. Cress the cartridge is not needed.

In general, vibratory kneading allows you to create a practically perfect concrete mix. However, it is also not optimal for the preparation of a "heavy" solution.

Milk bidon concrete mixer (flasks)

Concrete mixer with her hands from a dairy bidon

It is worth understanding that access to electricity is far from every summer cottage. Consequently, the self-made of a manual type and a small volume will be quite logical. Concrete mixer made of dairy flasks with their own hands - a very simple and uncomplicated option. You will need the bidon itself, pipe cutting or any other scrap metal like. It is possible to make it in 2-3 hours, the main spectrum of work falls on the boiling frame.

Taking a round tube, contact the handle, as shown in the picture. Top welding water clutches. Their diameter inside must exceed the diameter of the pipe that is used for the handle.
Skip the tube across the flask by making the holes, and then weld to the case.
It is imperative to find the center of gravity of concrete mixers with their own hands to twist it was easy. To simplify the design, you can do without using the coupling. Rubbed arcuate filings in the face and put the axis on them.

The unit, though simple, but not the most reliable. Therefore, it is better to use any other drawings for the manufacture.

Big barrel

Concrete mixer from big barrel 200 liters

A more practical option is the concrete mixer of 200 liter barrel. Why not two hundred liters? This volume is considered optimal for the kneading concrete at a time. Plastic option will noted immediately - such barrels will not serve you for a long time.

The homemade concrete mixer from the barrel is manufactured as follows:

Preparation of barrel, which has a lid and bottom. If the lid is missing, it is welded separately. Did not find the container? You can make it yourself. The homemade version is not inferior to the factory barrel. Tight metal sheets with a thickness of 1.5 to 2 mm thick, rollers, an effective welding machine and a wooden hammer.
To the lid and the bottom attach the flanges on which bearings are available. From the side cut the hatch where the solution components will be covered. A small trick - for a concrete mixer from a barrel such a hole should be taken closer to the end, which in the process of scrolling will be below.
Know how to make a concrete mixer with your own hands - still half of the case. It is equally important to establish the correct mixing of the solution. To do this, to the walls inside you need to weld the blades (angle from 30 to 40 degrees). Such angle is extremely important in the process of mixing the contents "pushed out" out. In principle, consolidate the blades you can and on the shaft.

How do the basis for concrete mixer professionals?

Naturally, a manual concrete mixer should have a stable base. It is necessary that the design does not start turning over during mixing. With a small loading of the island from a wooden bar, it will be quite enough (section 10 by 10 or 15 per 15 cm). Optimal connection options: "Spike" or "in Poltera". They are needed that the design does not receive damage from vibration. When the assembly is finished, all joints are sampled and tightened by self-drawing.

Need a more durable, durable unit? Then you definitely fit a metal corner. The welding machine is not all of all, but you can fix rivets or bolts.

If necessary, the wheels are screwed to the base. Such a device of concrete mixer will allow you not only to turn over, but also move it.

As for engines, the concrete mixer from the barrels can be equipped with a motor from a scooter or car. A good option will be a concrete mixer from a washing machine. The advantage of this option is that it is designed for long work and will be able to serve for several years.

Drawing of homemade concrete mixer from barrel

What speed to interfere with concrete?

We will not consider the process of kneading concrete in detail - this is the topic of a separate article. We note only the fact that the moment of twist plays a far from the last role.

That is why the "Washing" gearbox is better than an ordinary motor from a scooter or car. It can withstand almost any load and can work on low revolutions. 25 full cycles (revolutions) are enough enough.

To ensure such quantity, the gearbox may have a different scheme. The easiest, typical option, when the gearbox is made of belt and pulley. Concrete mixer with his own hands with a motor from a moped differs by mobility. Reducer is convenient and compact, no electricity is needed for functioning. Even if you have a large territory, the device made moves along it without free of care and hassle.

The gearbox in this case should be chain, otherwise the design will function well.

Instruction. We told you about what kind of manufacturing scheme should be. Clearly follow her to get the desired result. Any deviations in the work may lead to the fact that even a homemade concrete mixer from an old washing machine will be low-quality.

Frame. Do not even try to cook the metal frame with the cast iron. You significantly complicate your hard work.

Do not overload the design overweight. If a small amount of concrete is assumed, the barrel for 300 liters is definitely not needed.

Absolutely anyone can save a solid amount of money, if he knows how the concrete mixer is done with their own hands - the photo and video attached to the instructions. You will need a minimum building materials, tools, some attentiveness and resourcefulness. And the last advice on completion. If there is such an opportunity, it is desirable to attract one more (a better than two) people to work. Some steps must be performed at a time, and it is not very convenient to do it alone.
