Description

The invention relates to devices designed to create protective mineralized strips, as well as extinguishing ground fires with soil, especially in anhydrous forests.

A soil thrower is known, the working body of which is made with alternating cutting and throwing knives symmetrically located on the shaft, and a persistent gear wheel is mounted on the suspension bracket in front of the working body (AS No. 244204, SU, MKI 84d 3/02, bull. No. 17, 1969).

A disadvantage of the known device is that when cutting soil its working body has a high energy intensity.

Known soil-throwing machine for extinguishing ground fires, containing a frame that carries milling drums, actuators control the working bodies, a guiding casing, a throwing mechanism made with symmetrical blades pivotally mounted on a common hub (AS No. 277710, SU, MKI 84d 3/18, bull. No. 24, 1970).

The disadvantages of the known device are the high energy intensity, as well as the low efficiency of the working body.

Known frontal forest fire dredger, including a working body with knives, throwers, designed as a section of a spiral "wand", a soil throwing mechanism, a drive for controlling the working body mounted on the swing axis, issued for its center of mass (RF patent No. 2400274, A62C 27/00 , B65G 31/04, E02F 3/18, publ. 09/27/2010).

However, like analogs, the frontal fire-fighting soil thrower requires aggregation with the base machine, the working body is not deep enough in conditions of dense cohesive soils, and to increase the volume of soil supplied to the combustion zone, an increase in the number of parallel passes is actually required.

The invention solves the problem of increasing the efficiency of work on the creation of protective mineralized strips and extinguishing ground fires with soil.

The technical result consists in reducing the complexity of fire fighting and ensuring the spread of soil in the right direction.

The specified technical result is achieved by the fact that in a portable soil meter containing a working body with throwers, a control drive for the working body and a guiding casing, it is new that the working body is made in the form of blades mounted on a throwing disc and rotated relative to its radius in the direction of rotation by the angle β equal to 0 ÷ 90 ° is set perpendicular to the axis of rotation of the screw shaft for feeding soil, closed by a guiding casing made with the possibility of rotation in the plane of rotation of the working body. Portable soil thrower contains a mechanism for returning to its original position.

Figure 1 presents a General view of a portable soil thrower in its original position; figure 2 - portable soil meter in the final position; figure 3 - working body, the angle β is shown.

Portable soil meter (figure 1) includes a screw 1 with a shaft 2, the working body 3 (figure 3). The working body 3 is installed perpendicular to the axis of rotation of the shaft 2 of the screw 1, is closed by a guide casing 4, movably connected to the shaft 2. On the casing 4, the power plant 5 and handles are fixed 6. The support disk 7 is movably mounted on the shaft 2 with the inner disk fixed thereon from the machined surface side the pipe 8 and the rods 9. On the rod 9 is installed return springs 10, resting on one side on the surface of the support disk 7, on the other hand on the surface of the holding disk 11, rigidly mounted on the outer pipe 12, in turn, is rigidly fixed information on the basis of 13. The drive is carried out from the power plant 5, for example, a chainsaw engine.

The working body 3 of the portable soil meter is made in the form of blades 14 mounted on a throwing disk 15 with holes for supplying soil 16 and turned relative to its radius in the direction of rotation by an angle β equal to 0 ÷ 90 ° mounted on the shaft 2. Installation of the blades 14 at an angle β, equal to 0 ° ÷ 90 °, allows you to change the throwing range of the soil.

Portable soil thrower works as follows. The worker takes a comfortable position at a safe distance from the fire and sets the soil thrower on its base. At the same time, the need to clean the contact point of the soil thrower with the treated surface from materials that support the combustion process, as well as foreign bodies in the form of stones, etc., is either completely absent or easily performed by the worker using improvised tools, as does not exceed the diameter of the screw 1. After starting the power plant 5, the worker, applying a slight force to the handles 6, deepens the screw 1. In this case, the torque from the power plant 5 is transmitted to the shaft 2 of the screw 1, through which the soil is fed through the holes 16 in the throwing disk 15 to the blades 14 of the working body 3. As the screw 1 is deepened, the supporting disk 7 moves together with the working body 3, the casing 4 and the power plant 5 to the supporting surface along the axis of rotation of the shaft 2 of the screw 1. In this case, the inner pipe 8 is shifted to the outer pipe 12 with the simultaneous compression of the return springs 10 between the surface of the support disk 7 and the surface of the holding disk 11. Upon reaching the final position (figure 2), the worker stops the power plant 5, after which, under the action of the return springs 10, the installation takes its initial position (figure 1).

Throwing occurs as a result of imparting kinetic energy to the cut-off part of the soil from the blades 14. A guide casing 4 is used to direct the throwing soil. If necessary, the worker, using handles 6, directs the throwing soil stream in the desired direction.

Reducing labor costs is achieved by reducing the effort to move the device when extinguishing a local area of a bottom fire.

The use of the present invention improves the efficiency of work on the creation of protective mineralized strips and extinguishing ground fires with soil.
