Drill electric for earthworks with their own hands. Electrobur do it yourself for the earth. Types of rechargeable battery

As a fisherman, you learned how to carry Russian iceworks to the place of Klev, when on -20 ° C. As the owner, you experienced a sense of a person who had uploaded 20 yam shovel when building a fence.

Domestic ice rolls no longer attract you with their availability and disproportion. You come to the store for the sale of means of small mechanization in order to buy imported products.

The numbers on the price tag are significant, but the scope of work on your site does not correspond to them. Buy an expensive tool for seasonal work - an irrational solution. And you bought chainsaw once, and it was not so necessary.

This chainsaw can be turned into a presentable moto motor. Thanks to its ingenuity, you will receive two tools and save well.

Characteristics of Motoburov

If you doubt whether the homemade tool of time and effort is worth it, you don't know which volume of small earthworks can be completed literally per hour.

You can drill poles for pillars, lanterns, for trees disembarking, build foundations, make up a plot in accordance with your aesthetic taste and needs, without resorting to rent special equipment and manual digging.

If an earthen burner copes with some solid types of soil, the ice is more than a meter thick. In winter fishing, you will catch the fish, and not engage in driving.

Criteria that has a good motobur made by hand:

Power. For household needs, at least 3 horsepower. The power of engines of some modifications reaches 6 liters. with., But it all depends on the operating conditions.
You can manage the compact and light brown yourself, the more powerful will require the presence of another operator.
Engine volume Plays the same role as power. The larger the cubic centimeters of the fuel mixture holds the engine, the wider the possibilities of the motorcing.
The main landmark when choosing the volume is the nature of the soil. Alumina, sand, frozen soil require different engine characteristics.
Functionality, Drilling ability. What auger "pulls" the engine? What will be the diameter of the auger in millimeters? Is it easy to pick up a screw in the store, or do difficulty delivery arise?
Does the equipment of the screw extensioner include whether it is provided for a specific model? Having answered these questions, the user will be able to determine which tool he needs.

If you are interested in the independent manufacture of high-quality motility, you need to add that the fruit of your efforts will depend on not from talent. The process will require trial in turning and awareness of the principles of action of simple mechanisms.

There is nothing complicated in the manufacture of Motobur with your own hands. If you understand the gearboxes, you can disturb the sleeve of the desired diameter and build a high-quality mount.

Without some abilities, do not do here. Enjoy the support of a familiar lockster, if you do not own practical skills to work with the details.

Motobur from chainsaws

Faced with a similar question for the first time, you may be surprised that the chainsaw is used not only to saw wood. This is just one of the applications.

From chainsaws there may be a chic petrosis, winch, boring, motor for boat, deboker, device for dissolution logs on the boards, etc.

Functionality is provided with constructive features chainsaws:

unpretentious and reliable engine;
hermetic feeding of the fuel mixture, the leak of which is possible only if the chainsaw is flip over;
the main thing is understandable for all power take-off system. The output shaft of the chainsaw allows you to hang any nozzle.

Therefore, it is precisely chainsaws to take as a basis for a new device. It is not necessary to sacrifice it for the sake of Motobur: You disconnect the drilling nozzle, put the saw and cut the logs.

The engine chainsaw is designed for long-term and intensive operation, so you do not have to worry about breakdown or poor-quality execution of the task.

Theoretically, you can make a similar motorcing from trimmer, lawn mowers or grinder.

In practice, it is quite difficult due to the unusual gearbox. There may be problems due to insufficient power take-off or irregular rotation of the drilling auger.

Progress

So, how to make Motobur do it yourself from chainsaws?

Prepare chainsaw. In most cases, the Soviet Saw Pille "is used.

The auger should rotate at low speed. It is necessary to find a way to reduce revolutions so that there is as much as necessary to safely work with the Motoburn. Therefore, in order to make a motobore with your own hands, a gearbox will be required.

Klinorenny and worm gearboxes perform the same role, despite the constructive differences. But in this case, worm is preferable.

Note: worm transmission efficiency is lower than that of clinorem. The worm gear is heated faster, but it can be installed directly to the shaft of the base mechanism. No connecting couplings or mechanical gears do not need.

The big gear of the clinorem gear gear should lead to the movement of the auger!

You figured out the gearbox. But where to take it? It is better to buy. In the network you can find stories about brave, which, armed with a grinder, screwdriver and hammer, disassemble old tools and remove gearboxes from them. Also an option, but unreliable and barbaric.

Reducer and motor chainsaws should be copped. At this stage, you may need a locksmith. Usually the sleeve of the required diameter is mounted - it serves as a connecting link.

Need extra fasteners. You can not buy it anywhere. This is handmade, for each device the mount is selected individually.

Left pick up the bur and knives to it. Drill and auger should coincide in the direction of rotation if the device is a national team. The most popular - "tonnar", "Mora", "Hitachi". The cost usually does not exceed 5000 p.

Knives are desirable to pick up "relatives" and not Chinese production, especially if the motobur you will use for drilling holes on winter fishing.

Chinese burst, fall off, crack and they can not be restored by welding.

The homemade motorcing can be drilled well with a maximum diameter of 150 mm. What, how and how to boot, the best practice will prompt. Each chooses an optimal use option.

Motobur from drill

Making a similar device from a drill is much easier. High power - mandatory drill characteristic. It is better to take advantage of the perforator.

The process will be less laborious, because the gearbox does not need to look for - it is included in the perforator design. In addition, the borants belong to those devices that are aggregated with a drill without additional details.

The safety clutch is installed between the output shaft and the shaft of the drift drift. It prevents additional load on the gearbox and auger, so it will not get stuck.

Perforators are always equipped with a reverse, unlike a drill.

Make a Motobur with your own hands from a drill a little more difficult:

Need to pick a drill with a capacity of at least 2 kWhaving a receiver. Mark and year of release do not matter.
Buy worm gearbox (can be used) with a gear ratio of 1:25. You can purchase coaxial, but its use can bring inconvenience.
Auger - either buy, or cook yourself.
Creare all the items in a technologically completed design. Perhaps at this stage you will have to seek help, although if there is tools, materials and logic, you can construct fasteners yourself.
The main thing is that it be durable, careful and did not prevent the normal operation of the Motobura.

The advantage of chainsaws before the drill is its autonomy. The drill is running from the network, which narrows the spheres of its use, and the "chainsaw" Motoburn can be used in winter fishing conditions.

The advantage of the drill: the fuel mixture is absent, oil too. Drill can operate at minus temperature, and chainsaw freezes. It is necessary to spend time on its heating.

Memo driller

Creative inventors can mount motorcycles on the cart. If the tool is often used in the economy, it will be convenient.

Before independent manufacture of motorcing, calculate possible costs (gearbox, boring, auger, knives).

Compare with the cost of the new auger. If the difference in favor of homemade will be significant, it makes sense to make efforts to its manufacture.

The gearbox is not in vain is considered the most important element of Motobur. The number of revolutions at the output must comply with the requirements of the comfort.

The high number of revolutions will keep the driller in voltage, and the auger will continue to rotate even after the device is turned off. This is dangerous.

On the other hand, low revs lead to the lengthening of the time segment, which is required to perform a specific task. Hands and back will be tired.

Properly selected gearbox - the key to your "friendship" with a motoroburn.

Do you know how to choose a two-row in three criteria?

Of the interesting technical characteristics of the tower crane KB-403.

At the following address, an article is prepared for you to determine the choice of a hand-held cultivator for the cottage.

Do not run to the tool in the drilling process. It is hard to cope with it, especially when the auger gets on a stone. Be prepared for this and keep the distance.

Failure to comply with safety techniques threatens the same consequences regardless of whether you work with the factory or homemade tool.

Before work, break the hands of the hands - you will be more resistant to Motobur whims.

If old chainsaws, manual drills, drills, Bulgarian, are intense, do not rush to get rid of them on your attic.

These tools will help make it possible to make a new expensive device that will open up extensive opportunities.

Information obtained while watching video can be applied in practice - when creating a motobroad with your own hands:

The modern market is saturated with different kind of construction tools and devices. Take, for example, Yamobur: Today you can easily find a device, the cost of which is quite accessible, and the stated characteristics are fully satisfied with the buyer. It would seem that there is nothing easier: buy and use. But do not always hurry with such acquisition. The fact is that budgetary equipment in practice does not always meet the needs of the buyer, and it is not at all capable of performing functions entrusted to it: the brunt does not hurry to enter the ground, even with a strong press, the engine turnover falls from a large load, etc.

Buy a powerful and expensive device for a small volume of building or garden work - not always appropriate. Rent - too, pleasure not cheap. Therefore, the craftsmen to apply the equipment already available at their disposal to create compact drilling installations.

Earth Drill

In most cases, the mechanized yamobur is a power plant (a powerful drill or gasoline engine), which, using a simple mechanical drive, is connected to a conventional manual brown. Bur can be made independently.

Drill from drill do it yourself.

You can find a ready-made boring car.

skyle User forumhouse.

Many say that they bought just such a screw and secured it is a powerful low-robust electric drill.

Engine characteristics

Recommendations relating to the number of revolutions of the power plant and its other characteristics deserve separate consideration. Let's start with the fact that the power plant can be connected to the brown both directly and through an additional gearbox. The need to use the gearbox each determines for itself. As practice shows if the rated power of the drill is 2 kW, then there is no need for the reducer of the gearbox (especially if the installation does not have a special bed, and in the process of work it is necessary to keep it).

jumper_at_home. User forumhouse.

At first, the gearbox was planned, but after the field tests with the scheme - "Drill - Auch" was decided from the gearbox to refuse. The moment is that the operator does not notice at all (if you drill with your hands).

Power index - 2 kW - not happened by us. It is such a drill most often use the participants of our forum in the manufacture of mechanized yamobur.

Tri.dr.e. User forumhouse.

There is experience in building a column foundation with painter. Used a 2 kW and auger drill, calculated on the diameter of the pit - 30 cm (the diameter of the boosa is somewhere equal to 29.3 cm). For deeper drilling used an extension from a conventional steel pipe. The ground in me on that place is not sugar: the earth, then clay, then some kind of lens with beach sand, then again clay with sand, and then blue clay (at a depth -1.8 - 1.9 m).

In order for the units of the required depth in the land, the user had to build a compact drill unit (with a bed, winch and other auxiliary devices).

But now we are talking about the power of the power unit, and from the presented description it is easy to understand what a drill is capable of a rated power of 2 kW (even without a gearbox).

A bit of theory

If we consider the relationship between the power of the drill (or gasoline engine) and the torque on the shaft of the borax, it is determined by the following dependence:

N - Power (W).
M - torque (NM).
n is the number of revolutions (rpm).
9549 - Special coefficient.

Theoretically torque on the working shaft of such an installation during revolutions of 500 rp should be 38 nm (64 nm - at 300 rpm). But to calculate the torque, it is always necessary to consider the losses that define the efficiency of the device. The fact is that most of the manufacturers of the power tool indicate only the power consumption of their devices, and the output power (on the working shaft) by 1/3 ... 1/4 less consumed. Accordingly, less and torque. A 2 kW dry drill at 300 rpm will create a torque on spindle, equal to 64 nm, and approximately 48 nm.

Choosing a power unit for his yamobura, you can view devices with a power consumed less than 2 kW. But then seriously will have to think about the introduction of a lowering gearbox in the construction of a drill unit.

uVL77 User forumhouse.

Regarding the gearbox: the gearbox is good, because it allows, without changing the power, proportionally change the number of revolutions and torque. That is, reducing the number of revolutions through the gearbox, we proportionally increase the torque. And in this case the power remains a generalized characteristic (constant).

Focusing on a torque that creates a 2 kW drill (without an additional gearbox), you can choose a suitable device for your yamobura. In other words, knowing the drill power, the number of turns of its spindle and the gear ratio of the gearbox used, you can calculate the torque value that you get at the output of the power plant. But it should be understood that the speed of the rumble can not be greatly reduced.

uVL77 User forumhouse.

The optimal frequency of revolutions during drilling is from 60 ... 100 to 200 ... 300 rpm. Mode Depends on the type of soil, the method of drilling, varieties of drilling nozzles, the well diameter, etc.

In the above quote, drilling methods are mentioned. There are all two: continuous drilling and drilling with a constant removal of soil. For continuous drilling, the installation should ensure a large torque.

During drilling with a constant removal of the soil of the auger, driving into the ground to a certain depth, rises to the surface. In this case, the loosened soil located on the working blades of the auger is also extracted out.

The operation is repeated until the drilling system reaches a given depth. The process is time consuming, but it does not require large torque.

As we said, choosing a power unit for a drill unit, it is better to focus on a low-definite drill with a power of 2 kW (that is, to the torque that it transmits to the working shaft). Judging by the numerous reviews of Forumhouse users, these devices managed to prove well. Power of gasoline engines should also comply with the specified indicator.

Reducers for Yamobur and their varieties

The assembly of any mechanism in most cases is characteristic of the use of primary materials, devices and nodes that have long been idle, because they are not worthy of a worthy application. The experience of our users suggests that the reduced mechanical transmission can be made of a wide variety of details: from the spare parts to the moped person, from the uncomplicated chain or worm gear, from a suitable gearbox of unknown origin, which accidentally closed on the old shelf in the garage and so on.

Ensuring drilling gearbox, the main thing is not to forget about the optimal turns of the borax and that it is necessary to ensure a sufficient torque on its working shaft.

Mehanik020. User forumhouse.

My broken moped was lying around, I took the rear gearbox from him. Sawned the gearbox to the Turbine (the back of the aluminum case with the gearbox), then across the gear gear fixed to this gearbox, the electric motor from the old electropulum with a capacity of 2 kW. The engine with the gearbox gave the ratio - 13: 1 (at the output it turned out about 300 rpm).

About the chain transmission: possessing the famous fraction of the smelting, it is possible, without making great efforts, to build a completely reliable yamobur with sufficient power. The idea presented is not new, and many successfully apply it in practice (if there is a need for this).

jumper_at_home. User forumhouse.

There is no gearbox, although it was planned to manufacture from the GHM chain of the VAZ 2101 and its same asterisks. Transmission number - 1: 2. Tests showed that it is not needed. Is that at all solid soils to use it, but we have no such.

The application of the above mechanisms requires a non-standard approach to the build of a drill unit. If you have a small serial reducer (or it is possible to purchase it inexpensively), then the task becomes much easier. Here, for example, the photo of the gearbox shown by the user Melomandk.

Melomandk. User forumhouse.

Here is such a gearbox. That's just a gear ratio large - equal or even a little more than 1:40. Sizes (by body) - somewhere 15 x15 cm.

As it turned out, the device has quite suitable parameters.

di Griz User forumhouse.

My Yamobur based on such a gearbox. While I am very pleased. Engine - Bulgarian (3000 revolutions at the exit). Bulgarian power - 2 kW. Claine did not try, but a tough rammed land with the inclusions of the rubble and rotten roots of Yamobur took. A screw diameter - 160 mm, self-made knives on it - from the springs.

Stanina

If there is a lot of work, if you need to drill deeply, and it is very difficult to keep the installation in the hands, then the equipment can be fixed in a special bed.

Constructive execution at homemade stanis, as well as under low mechanical gears, may be the most diverse. But there are structural elements that are used in the overwhelming majority.

Lifting mechanism

As a lifting mechanism, you can use a chain transmission installed inside the central rack. Lifting and lowering is carried out either using an additional electric motor or with a handle (as in the photo from the user jumper_at_home.).

jumper_at_home. User forumhouse.

Major plunged by 1.8 m (auger + extension cord). I did not need deeper. Homemade winch - 2 gears and a chain from a motorcycle.

In order for the stove with the main electric motor without moving freely along the vertical tube, four rollers can be installed on the carriage.

Another lift design involves the use of steel cable and winch with an additional electric motor.

Mehanik020. User forumhouse.

On the square tube up and down the main electric motor of the drill rides. He moves at the expense of the winch (which I already had). This winch is needed in order to pull the boring of the ground from the well.

For convenience Mehanik020.made a remote controlling the winch and rotation of the boraxy during operation.

The drill, along with the soil on it, can create quite large loads on the winch. At a great depth, it will work on the principle of the piston, creating a vacuum and exacerbating the situation when lifting up. Therefore, the more powerful the winch is used, the better.

Dmitryevg. User forumhouse.

My winch is designed for 250 kg (500 through the polyspaster). Power - 1kW.

Lower support for the bed

The bottom support of the bed can be equipped with two wheels (for convenient movement within the construction site). If everything is done correctly, the installation by a simple tilt of the bed will be translated from the transport position in the working.

It is desirable to install adjusting screws on the support elements of the bed, which will help to put the car in accordance with the vertical level before starting work.

Materials for the manufacture of beds are chosen due to considerations of strength. Independently performing a complex calculation of the design of the structure is far from everyone, but anyone can take advantage of the experience of the participants of our portal.

So, user. Tri.dr.e.made a bed from a corner 50 * 50 * 5. Vertical supports and upper transverse bar are made of two bonded corners of the specified size.

User jumper_at_home. Lined in the design of the bed different metal profile with a thickness of the walls - at least 3 mm. The plot under the power plant was made by it from a steel sheet with a thickness of 10 mm.

But the installation photo that was created by the user Pwrww."From what was" (as he himself says).

Pwrww. User forumhouse.

The most difficult thing was to find two smooth solid three-meter pipes with a diameter of 60 mm. If they were not, I would buy a profile pipe for 80 or 100 mm. Below used a piece of channel 80 and a corner of scrap metal. Also among the scrap found 4 P-shaped plates of suitable length.

Ideally, the carriage should be made in such a way that, if necessary, the drill installation operator was able to become. It is especially important to comply with this condition on solid soils.

jumper_at_home. User forumhouse.

This is what was used to protect against drill turning: a stubborn corner of steel - 6 mm is screwed to the hole under the handle, which is available on the drill case. Everything is pulled by bolts with a sufficient plane of surfaces. If you want even more reliable - Provide a clamp under the planting protrusion, which is available on the drill convey.

Mechanical drive

The design of the mechanical drive connecting a drill or other engine with an earthen drill with a working shaft is not different. To create it, there is enough adapter, which is inserted into the cartridge drill (Morse cone, etc.) and the cylindrical sleeve, one end of the bark is welded to the adapter, and the other is dressed on the boome shaft. In order to increase the depth of the drilled hole between the drill and the brown, it is possible to insert removable knees made from the same material as the rod of the bora.

In order to prevent breakdowns when encamping the working body, the drive and the boron should be connected using a special protective heel. The stud is made of metal bar - 4 ... 8 mm. Testing the installation is better with a stud with a minimum diameter (4 mm).

Almost prof User forumhouse.

Imagine if you have a boring to stumble onto a stone and commit. I have a nail of 4 mm as a slide stiletto, and it never cut it. But if an obstacle meets, then he gives his hand in his hands.

Homemade

As we said, the working body of the installation (boring) can be purchased in a specialized store, but it is quite possible to make it yourself. Here, for example, homemade drill with removable blades.

For its manufacture, we will need a thick-walled pipe of a suitable diameter (30 mm), as well as material for blades and for their base. The bases to which blades will be screwed can be made from a thick metal sheet (6 ... 10 mm). The blades themselves should be made from high-strength heat steel (Art. 65g). If you need a small-diameter garden yamobur, then you can use ordinary springs from the truck.

For the manufacture of blades, you can use discs from a circular saw.

The diameter of the borax should be 5 mm more than the diameter of the drilled holes.

We present to your attention a sketch drawing of the product.

Throwing the upper handle, we get exactly what we need.

The design of the homemade drill must comply with the following parameters:

The angle between cutting blades (between blades) can vary within - from 25 ° to 30 °.
The front edge of the blade is sharpened at an angle of 45 ° ... 60 °.
To the lower end of the bora, it is desirable to weld a thick drill on the metal, thanks to which the installation will be easier to enter the tight soil.

As a garden borne to fix in a drill.

If during the excavation work on the site you need to dug a few holes well for pillars or racks, then the garden drill model Fiskars Quikdrill will help significantly accelerate this process.

Electric manual screw Jamobur bison, tornado or fiscars, is able to significantly alleviate the entire process of land. In addition, Garden Drill Fiskars Quikdrill Models can drill holes in soil at such depths as 100, 200, 300 or 500 mm.

Electric manual screw jambur bison, tornado or fiscars can form a hole in the soil for trees and shrubs.

1 Purpose and Characteristics

Currently, drilling work is carried out everywhere due to the incessant and developing country construction. In most cases, such aggregates as an earthenware Jamobur bison, a tornado or fiscars are used in drill operations at dachas and country sites.

It is worth noting that the garden drill model Fiskars Quikdrill and its analogues such as bison, tornadoes and fiscars are able to create holes in the soil for:

Installation of fence posts;
Mounting piles;
Bookmarks of the pile foundation with a depth of 100, 200, 300 or 500 mm;
Creating shallow trenches and technical openings;
Planting shrubs of seedlings and small trees.

The screw homemade Yamobur is represented as an electrical device, which refers to the category of tools for cutting.

Such common aggregates like bison, tornadoes and fiscars have excellent feedback from users, and are able to do holes with depth indicators 100, 200, 300 or 500 mm in such materials as:

A rock;
Concrete;
Brick;
Saturated pebbles soil.

Structurally, manual earth auger homemade Yamobur, similar to a conventional drill, equipped with a shank and a spiral. Due to the presence of such a helix, such aggregates as a bison, tornado and fiscars are capable of not only to create holes in a depth of 100, 200, 300 or 500 mm, but also to make a removal from the drilling zone of the waste material.

Earthy manual screw Jamobur is made of materials with excellent performance indicators. Its cutting part is made using a alloy with a high degree of hardness.

The rendered screw manual Yamobur Tornado, bison, fiscars, and similar to them, have several configurations for sharpening the cutting edge.

A distinctive feature of such portable devices, as a hand-made namobur Tornado, bison or fiscars is the presence of an electric motor equipped with two comfortable handles.

The electric motor is equipped with a special clamping type mechanism in order to fix the drill tool - auger. The auger in such aggregates, as a manual namobur Tornado, bison or fiscars is represented as a rod with a solid screw surface along the entire longitudinal axis.

2 What are the features of the garden electric bora?

Electrobur is represented as an electric bottomhole machine, which is equipped with an electric motor that is mounted in the device pipe case.

The housing ensures the movement of the drill bit during the work. The well, created with the help of such an aggregate, can last a long time.

Reviews of the unit presented for the most part are good. All modern products are equipped with an asynchronous oil-filled engine equipped with a short-circuited type rotor.

Thus, the main parts of the electric borax is an asynchronous oil-filled engine and a spindle that is located on rolling bearings.

Inside the pipe case is a stator mechanism magnetic conductive steel package. This compartment is separated by non-magnetic steel packages in those places where radial ball supports of the rotor are located.

All rotor packets are covered with a layer of aluminum winding and included in the hollow rotational motor shaft. Inside the cavity of the engine is filled with a special variety of dry insulating oil.

In addition, the inner cavity of the engine is hermetically fenced with the upper and lower seals. When starting the system, the glands are filled with oil.

In order to compensate for oil leaks and to support constant internal pressure in the engine in the upper part of it, so-called lubricators and three glands are placed.

Each of the glands is equipped with a cable input, which is served from the edge of the contact rod, and, passing through the glands, is connected to the stator winding.

In order for the weight of the rotating shaft to be perceived by the whole mechanism, the lower part of it is equipped with a steady ball bearing installed.

Spindle is attached to the bottom cover of the engine. It is equipped with a multi-row axial support that moves due to the presence of ball bearings.

In the case, another shaft is moving, which is inside the hollow, and its centering is made with a number of ball bearings. There is a connection between the spindle shaft and the main motor shaft.

It is implemented using a junction coupling of a toothed shape. In the place where the shafts are connected, there is a seal of a hinge type.

It provides a high degree of waterproofing from the flushing fluid ingress. All axial loads that are subjected to a rocking shock tool (auger) are completely absorbed by the spindle housing and are not transmitted to the motor shaft.

All types of asynchronous engines that are used by electrical workers have a sufficiently limited operating range of the rotational frequency.

Changing this parameter directly depends on the speed, which is capable of sliding the rotor relative to the stator field. Thus, the motor torque value directly depends on the voltage square at the input.

When the voltage decreases, then there is a significant reduction in the torque. Based on this, the voltage drop in short-term loads, it is necessary to compensate for the increasing voltage at the engine input by 10-15% of the nominal level.

Depending on the characteristics and variety of the engine, the voltage in the terminals of the electrical armor can be from 1000 to 1200 V. at the moment when the engine is started, a significant reduction in torque is observed is the so-called failure zone.

Then this parameter is restored after the unit output to the normal working pace. Due to the fact that the launch of the engine is made with an indicative of a small degree of load, the mask moment of all parts involved in rotation is very small.

However, even if the torque is strongly reduced, the engine is capable of accelerating the frequency of rotation of the working shaft in a matter of seconds.

By the way, the efficiency of such an engine, when testing the rated load can be about 70%. This is due to a small level of mechanical losses during the movement of the spindle at fixed points of supports.

The supply of electricity to the engine carrying the drilling is made using a partitioned cable. It is located in the inner channel of the drill column.

Current is performed using a three-time cable. Instead of a third wire, a drill column can act.

It should be borne in mind that the cable support of the electric garden drill is generally considered one of the weakest nodes of the system represented.

The voltage may fall due to the disturbed tightness of the segments of the cable and their further contamination. Disorders in the operation of electrocups is observed when the contacts made using copper are broken, in those places where they are connected to the coupling.

It is worth noting that a portable hand-made garden burden has a number of advantages that are expressed in:

Facilitate the conditions when working a drill column;
Reducing wear located in the well;
Minimizing power costs at idle.

In addition, the operation of the unit does not come into contact with the fluid flow rate. Therefore, the device shows the greatest efficiency in the case when the hole in the ground will be completely cleaned from the sludge accumulated there.

In addition, the working cycle of the device does not depend on the quality and characteristics of the solution used during drilling. Such a property implies the use of the product in working with tensile solutions.

The communication channel for monitoring the work performed by the unit is presented in the form of a conductor. This allows the device to remotely carry out drill operations in some modifications.

Due to the fact that manual electrical equipment is represented in the form of an oil-filled engine, all parts of its parts lead work in an environment that is isolated from sludge.

Based on this, the rotational elements of the auger in the smallest degree are exposed to malicious corrosive and abrasive processes.

Among the disadvantages of such a device, it is possible to highlight a sufficiently high cost, compared with mechanical counterparts. The probability of obtaining damage and curvature when grabbing in the wellbore and the low degree of reliability of the cable connection.

Sergey, 45 years old, Samara:

I decided to equip my country household plot and put a grid fence. In order to make small wells for baking columns used a manual electric boring, which borrowed from a neighbor.
All the work performed in the shortest time, while not spending great effort. Excellent aggregate. I read the reviews - now many in the farm have such a thing, so I decided to buy it myself. I advise everyone!

Vladimir, 53 years old, Voronezh:

Today, no one will surprise the fact that experts often use electric electric or gasoline. This allows them to significantly reduce the drilling time, and physical efforts with such equipment a person practically does not spend. In this article, the maximum attention will be riveted to the electrical equipment for earthworks.

Modern borants - what kind of choose?

Initially, let's figure it out, what borants today exist. All models can be safely divided into three types.

Manual borants. This species is used for drilling, as a rule, single holes. When it is used, it is necessary to apply a lot of physical strength.
Gasoline bora. This type of equipment is very common. It can be used for both individual construction and professional. Powerful and productive aggregates.
Motobra electric. These aggregates are not so powerful as gasoline, however, their operation does not require much physical effort. They are convenient for individual construction, when drilling holes for pillars, when landing trees and bushes. However, it is worth remembering that the garden electric train will only work with the extension cord for the electrical network.

By summing up, we can conclude:

the first view is simple, but not produced,
the second type is powerful, productive and can be used when working on any soils,
the third type (electric car) is less productive, requires a wired extension agent, can be used in individual construction.

Given these characteristics, you can easily choose exactly the bur, which is suitable for you!
Consider the technical characteristics of the two models of electrosumburov.

Electrical Mode Texas EA1200

Consider its main technical specifications:

power 1200 W;
maximum drilling diameter 150 mm;
maximum drilling depth of 800 mm;
created noise level 90 dB;
weight of 12.8 kg.

Specifications:

power 1050 W;
maximum drilling depth 1 m;
range of drilling diameter 80 - 200 mm;
weight of 14 kg.

As can be seen from the technical characteristics presented, electrical yamobura is significantly inferior to some models that operate on a gasoline engine. Therefore, if you need often a lot of soil, then you should give preference to gasoline equipment. For rare use, electrical is perfect.

It is possible to make any boring with your own hands, however, for the manufacture of electric or gasoline bora, you will need a lot of details, tools and solid knowledge luggage. Therefore, if you thought about the homemade storm, then you are easiest to make a handberry manual.

For its manufacture, you will not need a lot of material and a special tool. Special attention in the manufacture should be paid on the Bura blade. Often for the manufacture of blades use a disk from chainsaws. Its with the help of the "Bulgarian" is cut into two parts and at the angle welded to the rod. Such a boring can be used in a private farm, but it is worth understanding that it will be necessary to apply a lot of physical forces during its operation.
