Description

The utility model relates to devices designed for laying protective mineralized strips, as well as extinguishing ground fires with soil, especially in waterless forests.

Known frontal forest fire soil thrower, [Author's certificate RU patent No. 2400274, IPC class. А62С 27/00, B65G 31/04, E02F 3/18, 2010], containing a working body with throwers, a soil throwing mechanism, a working body control drive and a guide casing. The working body is installed on the swing axis, which is placed beyond the center of mass of the working body, is closed by a guide casing connected through a lever to a loading hydraulic cylinder for raising and lowering the working body, is made in the form of throwing knives, designed as a section of a spiral rod, mounted on a milling disk at an angle α between the rear edge of the knife and the plane of rotation of the milling disc and rotated relative to the rear edge in the direction of movement by an angle β.

The disadvantage of this device is that in practice, in the process of soil throwing, part of the cut soil, due to the lack of support, “comes off” from the throwing knives of the working body, while remaining in a groove cut in the soil, thereby reducing the mass of soil distributed over the width of the mineralized strip .

The closest analogue to the claimed is the working body of the forest fire ground thrower [Author's certificate RU patent No. 117091, IPC class. А62С 3/00, А62С 27/00, 2012], containing knives-throwers placed on a carrier disk mounted on a shaft, made in the form of a rod spiral section and mounted on a carrier disk at an angle α between the trailing edge of the knife and the plane of rotation of the carrier disk , and rotated relative to the trailing edge in the direction of motion by an angle β.

The disadvantage of this design is the lack of a safety mechanism that protects the knives-throwers and the disk from breakage when they encounter insurmountable obstacles in the form of stones, thick tree roots, etc., which reduces the coefficient of technical readiness and productivity.

The technical result of the utility model is to increase the coefficient of technical readiness and productivity.

The technical result is achieved due to the fact that on the shaft, behind the carrier disc, a flat elastic casing is rigidly installed, with a diameter equal to the diameter of the blade movement trajectory, the carrier disc has a small diameter sufficient for fastening throwing knives, there are four knives on the carrier disc - thrower, attached near the outer edge of the disk hingedly, with the possibility of angular rotation along the plane of the disk, the stalk of throwing knives is located along the plane of the carrier disc, and their cutting and throwing part is bent at an angle α from the plane of rotation of the carrier disc, at the end closest to the center of the disc, the knives - throwers have a vertical hinge, the hinges of adjacent throwing knives are connected by rods, forming a quadrilateral, and the same hinges are connected crosswise by tension springs stretched with a given initial force sufficient to hold the throwing knives in the working position without meeting them with insurmountable obstacles in rocks or thick tree roots.

The specified set of essential features ensures the appearance of the proposed working body of the forest fire soil thrower with new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty".

Figure 1 shows a diagram of the working body of the forest fire soil thrower, front view, figure 2 - the same, top view.

The working body of the forest fire ground thrower, containing placed on the carrier disk 8, mounted on the shaft 7, knives-throwers 1, made in the form of a rod spiral section and mounted on the carrier disk at an angle a between the rear edge of the knife and the plane of rotation of the carrier disk, and rotated relative to the rear edges in the direction of movement at an angle β, characterized in that on the shaft 7, behind the carrier disc 8, a flat elastic casing 2 is rigidly installed, with a diameter equal to the diameter of the trajectory of the knives 1, the carrier disc 8 has a small one, sufficient for fastening the throwing knives 1 , diameter, on the carrier disc there are four throwing knives 1 attached near the outer edge of the disc 8 hingedly, with the possibility of angular rotation along the plane of the disc 8, the handle of the throwing knives is located along the plane of the carrier disc, and their cutting-throwing part is bent at an angle α from the plane of rotation of the carrier disk, at the end closest to the center of the disk 8, the throwing knives have a vertical hinge 4, the hinges of adjacent but throwers are connected by rods 5, forming a quadrilateral, and the same hinges are connected crosswise by tension springs 6, stretched with a given initial force sufficient to hold the throwing knives in the working position without meeting them with insurmountable obstacles in the form of stones or thick tree roots .

The work of the working body of the forest fire ground thrower is carried out as follows.

The deepening of the working body is carried out along the lower point of the disc 8, which eliminates the friction forces of the disc on the soil and the likelihood of its breakage when it encounters an insurmountable obstacle and increases the coefficient of technical readiness.

During operation, throwing knives separate the chips 9 from the soil mass 10. Throwing occurs as a result of giving the cut part of the soil kinetic energy from the throwing knives.

The elastic casing 2, moving along the groove formed by the throwing knives 1, feeds the loose soil that has crumbled into it into the capture zone of the throwing knives and thereby ensures throwing the full volume of the cut soil and increases productivity.

When the knife-thrower meets an insurmountable obstacle, the knife-thrower leans back relative to the hinge axis 3 of its hinged attachment to the carrier disk 8, the configuration of the linkage system 5 changes, the corresponding spring 6 stretches and the knife-thrower bypasses the obstacle from above.

After bypassing the obstacle, the elastic force of the stretched spring returns the knife-thrower to its original working position. The elastic casing bypasses the obstacle from above and restores its position due to its elastic deformation. At the same time, stopping the unit is not required, the probability of breakage of the working body is reduced, and the coefficient of technical readiness and productivity are increased.
