Yamobur on MTZ-82, 80: types, technical characteristics

Types of hole drills, operating features

The need for this equipment arises when vertically installing various types of structures into the ground or in agriculture when planting seedlings .
In addition, hole drills can be used for drilling holes in ice during winter fishing. The capacity of the equipment depends on the volume of planned work. Pit drills are conventionally divided into the following main varieties:

1. Manual:
   Motorized (gasoline or electric engines are used as a power drive).
2. Non-motorized (driven by the physical effort of the operator).
3. Mounted.

Mounted hole drills

To operate this equipment, the operator does not need to use his physical strength - the dimensions, weight and power of the machine on the base of which the hole drill is mounted are used.
It is interesting that such units are not only factory-made; quite often there are also home-made devices, which, if you have the necessary tools, materials and skills for their manufacture, are much cheaper than factory ones. Most often, wheeled vehicles are used as a basis, but if holes need to be drilled in hard-to-reach places, then it is better to use tracked tractors or all-terrain vehicles.

Manual hole drills

The simplest version of a manual hole drill consists of the following parts:

1. Powder coated steel base.
2. Steel helical blades located on the bottom of the base.
3. A handle attached to its upper part.

The number of blades, their diameter, the length of the base, as well as the design of the handle are very different. The unit can be collapsible and can also be equipped with various kinds of additional attachments.

The maximum drilling depth for various models of a manual version of a gasoline hole drill is from one to three meters. This indicator varies depending on operating conditions and equipment configuration of the device.

Hand-held hole drills can even be used to perform large-scale work, such as installing bridge supports or forming holes for pouring a foundation.

The equipment, in which the role of the power plant is played by a gasoline internal combustion engine, is completely autonomous due to the presence of a large fuel tank. As for electric driven hole drills, they are either equipped with a rechargeable battery, which lasts for a fairly short time, or are powered via a cable from the mains, which significantly reduces their mobility.

The force from the engine in gasoline units is transmitted through hydraulic or mechanical transmissions. This equipment is most often operated by one person, however, there are high-power models that require the physical strength of two operators to fully operate. Some types of hole drills can drill at different angles .

There is a wide selection of units on the market - from lightweight portable models to professional hydraulic ones, which are equipped with extensions that significantly expand the range of their functionality.

What should you pay attention to first when choosing equipment for drilling wells?

The most important initial data for the correct choice of unit are:

1. Its general characteristics.
2. Power of the power plant.
3. The maximum diameter of holes it can drill.
4. What is the purpose of a hole drill - is it for household or professional use?

2. When planting a large number of shrubs or trees.
3. In deep loosening of soil.
4. In installing fences.
5. In arranging trellises for climbing plants.
6. When laying communications.
7. In drilling wells.

Types of hand drills

Homemade devices help with small volumes of excavation work. It should be remembered that working with a manual hole drill requires considerable effort. If the wells are deep or there is hard soil, it will not help. If you have to install piles or a long fence, then drilling holes can take a lot of time. Renting a hydraulic drill or purchasing a reliable motor drill will be the best solution in a difficult situation.

Types of manual hole drills by type of drive:

1. Manual mini hole drill without drive.
2. Gasoline motor drill.

Petrol hand drill

The device, powered by a gasoline engine, allows you to drill holes in soil of any hardness. The absence of connection to a power source makes the tool autonomous. You can work with it in the field and even on a river for drilling ice. In the latter case, a nozzle with a stronger cutter angle is required. A modern gasoline hole drill is equipped with shock-absorbing springs to reduce vibrations and unpleasant vibrations, which makes its operation more comfortable.

Types of gasoline hand drills:

1. Heavy
   – professional equipment for hard soils with high power, equipped with a 3 or 4 stroke motor, requiring 2 operators to operate.
2. Lungs
   – amateur equipment, operated by one operator. Suitable for drilling wells up to 2 m deep in black soil, sand or loam.

Electric manual hole drill

The design of this device consists of a compact electric motor with two handles and a clamping mechanism for fixing the auger-type working mechanism. Electric drills are less common than motorized drills. At the time of peak loads, the electric motor, connected to the auger using a rigid coupling, heats up more and breaks down more often. With a tool power of 1200 W, it is barely enough to drill a 150 mm hole in garden soil.

1. Relatively silent operation.
2. Quick readiness for work.
3. Highly environmentally friendly.

Disadvantages of electric manual hole drills:

1. The range is limited by the length of the connection cord.
2. At lower voltage, the engine heats up more.
3. The reliability of the tool is worse compared to a gas drill.

Hydraulic manual hole drill

The cost of such a device is high; when used on a garden plot for one-time use, it is more profitable to rent it. A hydraulic hole drill is a productive and powerful technique that allows you to drill holes with a diameter of 30 cm and a depth of up to 5 m (using extensions up to 30 m). The drive is carried out from the hydraulic system of the tractor or a special mobile station. The weight of the hand tool is about 30-60 kg.

Advantages of a hydraulic drill:

1. The presence of a reverse function allows you to drill in all directions, which makes it easier to pass through hard, problematic soil.
2. Hydraulics absorb the main vibration loads, so working with such a drive is more comfortable.

Purpose and types of pit drills

Yamobur

– universal special equipment for drilling holes, wells, holes of different depths. It significantly facilitates and also speeds up work, without the use of physical force. This equipment is used to perform a variety of work, not only construction.

Pit drills are called both manual and mechanical equipment. All of them can be divided into four types:

1. Manual.
   To use them you do not need to have much knowledge or professional knowledge; they are quite easy to use. The tool is indispensable and widely used in dacha farming. The drill consists of a drill with augers, a handle and additional extensions. The most common ones have a diameter from 50 to 110 mm with a drilling depth of up to 1.5 m.
2. On a tractor basis.
   It is an attachment for carrying out larger work, producing holes 1-2.5 m deep and up to 20 cm in diameter. The attachment itself is small in size.
3. Based on a car.
   This special equipment drills wells up to approximately 20 m and is mainly used for large-scale construction. The vehicle's high cross-country ability allows it to be used in off-road conditions and in regions with harsh climates.
4. Drilling rigs.
   A complex of drilling structures and structures is used mainly when working at great depths. But it is still possible to drill shallow wells with a diameter of 2-3 m to a depth of 32 m, during geological exploration and engineering work. To an average depth of up to 650 m for structural exploration of solid minerals. Or deep exploration and production wells for oil and gas up to 6200 m.

There are also several types of drill

• Annular;
• Non-removable;
• Collapsible;
• Auger.

What kind of work are pit drills used for?

Yamobur is a universal special equipment for drilling holes and wells. It is used in many areas, from gardening, where it helps plant seedlings, to construction, for drilling holes in the ground for poles. It can be used even for small geological studies, as well as laying electricity lines. The use of this technology will replace the physical labor of dozens of people and increase the speed of work.

What to look for when choosing a hole drill

The choice of hole drills is very large, which means that you can find special equipment that meets all the necessary requirements. A petrol pit drill is well suited for small earthworks; it is popular in summer cottages and gardens for planting green spaces, installing fences and enclosures. It is often used by fishermen. During construction work, it is better to use a pit drill in Moscow and the Moscow region on the basis of a car; its drilling depth is much greater than that of a manual one, and it is more mobile in comparison with drilling complexes. In cases with poor road traffic, a GAZ or KAMAZ-based hole drill is well suited. The Yamobur all-terrain vehicle will be able to perform the assigned tasks in any conditions.

When choosing equipment, carefully consider the entire process of future work and possible difficulties during drilling:

• Find out the category of soil, the presence of rocks;
• Determine the depth and diameter of the well;
• If you use a car as a base, you should take into account the length of the boom reach.

The equipment is selected based on the basic parameters and technical characteristics. In order not to miscalculate and take into account all working aspects, you should consult a specialist in this field.

How to choose a hole drill?

Let us immediately note that it is easier for compact installations to find application on the farm, using them for loosening, planting bushes, and fishing.
