All about Motobura

Motobur (Benzobur) is needed in the farm for carrying out earthworks and to install columns. This tool is applied in cases where you need to speed up the results of manual labor. Before choosing a suitable model, it is worth examining not only the rating of the best offers, but also presented in the species market. Master the drilling with manual gasoline yamburas is quite simple – detailed instructions will help how to understand everything.

What it is and why you need?

Motobur – Specialized Tool Variety for Earthworks. With it, the openings of the desired diameter and depth in the ground are created. This portable drilling unit consists of a transmission and a gasoline engine, with reduced coaxial or worm-type gearboxes. The grip is used by the centrifugal, it is with its help “the rotation is fed to the auger. Also, the tool always has 2 horseshoe-shaped handles, which operator keeps in their hands while working.

In models of hydraulic drive, mechanical elements are replaced by a system with a pump and a hydraulic motor that reduces wear. Such equipment requires less strength and time in the process of working with it. It is optimal when drilling wells with a diameter of up to 20 cm with a depth of 1.5 m.

Regardless of the design of the Motobur itself, in working with it are used predominantly screw nozzles having a spiral design. On the waist removed soil rises to the surface. With some types and drilling methods, column type tools are used as well as suspension nozzles.

Types of knives are also selected, based on the density and features of the soil on which it will be necessary to work.

The main characteristics that boiled can be like, look like this:

  • Motor power in the range of 1.3-21 liters. with.;
  • Mass of the device 7-250 kg;
  • Engine torque 75-1200 nm;
  • drilling diameter up to 500 mm with a depth of up to 10 m;
  • Transmission type hydraulic or mechanical.

Appointment of the tool It is impossible to limit the narrow spectrum of tasks. Motobura are focused on using as a utility tool in the household, it is also used by specialists in carrying out work in construction. With the help of a mechanical and hydraulic instrument, holes are created in the soil of different diameters, destination. The most common areas of its use are.

  1. Repair and strengthening foundation.
  2. Conducting work in the field of geological exploration.
  3. BEGEGRUE. Using drilling prepared holes for columnar foundations in the ground. They are used as protection against shirling shores, pvov, catlovanov.
  4. Preparation of pits under the poles. Using a drill, a holes for the supports of the fence, the foundation, the elements of the lighting system, thresholds are prepared.
  5. Installation of heat exchange systems.
  6. Linear Communication Laying for Lighting Systems, Power Supply.

Motobura with a gasoline engine can be used even in conditions close to extreme. They are successfully used by researchers in the Arctic and Antarctic. When preparing space missions, this type of tool is considered as the main device for sampling.

The principle of the device is pretty simple. Like ordinary mechanical yamobura, gasoline varieties are installed on the point. After starting the engine, the auger is started. The tool must be located vertically, gradually plunging to the depth – the main efforts of the operator are sent to keep the device strictly perpendicular to the Earth. The selected soil rises in a spiral.

Benzobur is a pretty popular tool that allows you to significantly increase the productivity of manual labor. Depending on the design and features of the structure, the hydraulic and mechanical version of this equipment is distinguished. In addition, there is a professional tool that allows you to significantly increase the depth of drilling. All models are equipped with screws with a screw, but there are options with reverse – reverse.

Choosing gasoline yamobur, it is worth carefully learning all available types of such equipment.

By destination

The main classification of motorized devices for drilling implies their division into groups by appointment. Severate garden or household models, calculated on the removal of small holes in a depth of 2 m. This is enough for most types of earthworks:

  • for notching soil;
  • for land (landing plants);
  • For municipal improvement of land plots.

A distinctive feature of household drills can be called the readiness of the tool to short-term, not too frequent operation. Such models are not focused on intensive work in daily mode. Such a boring is suitable for fence posts – when preparing holes. A screw diameter in garden models rarely exceeds 150 mm.

Professional Boer – Powerful, Large-sized, Holding Significant Operational Loads. It is used when spinning piles and other complex manipulations. Such models are distinguished by a significant depth of immersion. For example, when drilling a well to water uses nozzles with an elongated screw.

Professional borants with a gasoline engine can maintain a long continuous operation. They are equipped with larger diameter screws, the nozzle immersion velocity can also be varied in the desired range.

According to Gabaritam

All popular benzobuurs available on sale can be divided into 3 large groups.

  1. Lungs. The equipment of this type has a mass of up to 30 kg, cope with it for 1 operator. The brown can create wells for small depths in light and loose soil. The bundle includes auger to 150 mm and a two-stroke motor, the speed adjustment is usually not provided due to the low power of the equipment.
  2. Heavy. These are large-sized equipment, having a lot of up to 80 kg. They are equipped with handles designed for 2 operators – all of them 4. This type of equipment is focused on working on dense and complex soils – clay, chernozem. The benzobur is equipped with a powerful four-stroke motor, a multi-stage gearbox, the bur has an extended design, provides a wider range of rehabilitation.
  3. Professional with vibration. They refer to the category of heavy, the jet rod is additionally included in the package. Such an addition reduces vibratory loads, allowing you to cope with the work of only 1 operator.

By speed of rotation

For this indicator, all the motobra are divided into one-speed and two-speed. The first category includes household models. To the second – professional used on different types of soil.

The feasibility of acquiring an expensive multi-speed model is determined on the basis of the estimated volumes and complexity of the tasks being performed.

By management

According to this indicator, the motobura is customary to be divided into mechanical and automatic. First have to be turned on manually. The automatic start of the engine and the rotation of the auger is carried out by pressing the button.

It is much more convenient than to start the motor manually, jerk.

Heavy and lungs

The classification of this indicator is somewhat different from the one that is applied by dimensions. Light motobra have a design designed for manual carrying, moving, installation. You can manage them with a small depth of drilling 1 person. Heavy models are equipped with wheels fixed on the frame. It greatly facilitates their transportation.

By type of design, heavy wheeled boraners can be.

  1. Modular. With the separation of gearbox and motor on different platforms.
  2. Single-family. Such models involve the fastening of all parts into a single block.
