A tool for processing solid soil on slopes, including a rigid stand, attached to the stand with the possibility of detachment, an elastic V-shaped plate with a front edge sharpened at an angle of 40 ° in the part interacting with the soil, connected to the stand by plates and bolts, a working element in the form of a cone with a half of the horizontal symmetry plane cut off at the bottom, a plate in the form of an isosceles triangle with pointed side edges protruding outside the cone, fixed to the conical part with flush screws, and a blade knife 0.02 meters thick and 0.08 meters high with a curved front edge sharpened at an angle of 45 ° is welded to the plate from below along the longitudinal axis of symmetry perpendicular to the surface.

Description

The utility model relates to agricultural engineering, in particular to implements for tillage.

Known tillage tool [Author's certificate RU patent No. 2120710, IPC class. А01В 35/02, А01В 35/20, 1998], which contains loosening working bodies with vertical plow blades installed on the frame in a row at an acute angle to the direction of movement. The profile of loosening working bodies is made in the form of a part of a conical surface with a convexity upwards.

The disadvantage of the known tillage tools are labor-intensive operations to replace the working bodies with subsequent adjustment and significant costs of energy and mechanical resources when using them.

The closest analogue to the claimed is the destroyer of the structure of solid soil [Author's certificate RU patent No. 271699, IPC class. А01В 35/02, А01В 13/02, 2020], including a rigid stand attached to the stand with the possibility of detachment, an elastic V-shaped plate with a front edge sharpened at an angle of 40 ° in the part interacting with the soil, connected to the stand by plates and bolts, a working element in the form of a cone with a half of the horizontal symmetry plane cut off at the bottom, an isosceles plate triangle with pointed side edges protruding beyond the cone, fixed to the conical part with flush screws.

The disadvantage of this design is the instability of the movement when cultivating the soil on the slopes.

The technical result of the utility model is to increase the stability of movement on slopes when processing solid soil.

The technical result is achieved due to the fact that a plate knife 0.02 meters thick and 0.08 meters high with a curved two-sided front edge sharpened at an angle of 45 ° is welded to the plate from below along the longitudinal axis of symmetry perpendicular to the surface.

The specified set of essential features ensures the appearance of the inventive tools for processing solid soil on the slopes of new properties that are different from the prototype.

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

In FIG. 1 shows a diagram of a tool for processing solid soil on slopes, side view, in Fig. 2 is the same, front view, in Fig. 3 - the same, bottom view.

A tool for processing solid soil on slopes, including a rigid stand 3, attached to the stand with the possibility of detachment, an elastic V-shaped plate 2 with a front edge sharpened at an angle of 40 ° in the part interacting with the soil, connected to the stand 3 by plates 4 and bolts 5, a working element 1, in the form of a cone with a half of the horizontal symmetry plane cut off at the bottom, plate 6 in the form of an isosceles triangle and with pointed side edges protruding beyond the cone, fixed to the conical part with screws 8 flush, and a plate knife 7 0.02 meters thick and 0.08 meters high with a curved double-sided front edge sharpened at an angle of 45 ° is welded to the plate from below along the longitudinal axis of symmetry perpendicular to the surface.

Tool for processing solid soil on the slopes works as follows.

During operation, the pointed edges of the plate 4 in the direction of travel are the first to interact with the soil. They cut the soil layer, then the working element 1, with its conical surface, raises this layer to the height of the radius of the base of the cone, while tensile stresses arise in the soil and cracks (microcracks) appear, the maximum value of which is realized at the highest point of the base of the conical surface, where the rack 3 moves with an elastic V-shaped plate 2 with a front edge sharpened at an angle of 40 °. The interaction with the soil is of a secondary nature, since it moves in the zone of already destroyed soil with less resistance.

A plate knife 7 0.02 meters thick and 0.08 meters high, welded to the plate from below along the longitudinal axis of symmetry perpendicular to the surface, with a curved front edge sharpened at an angle of 45° on both sides, cuts through the undestroyed dense layer of soil below the plate 6, forming a vertical slot. Curvilinear, sharpened at an angle of 45°, the front edge of the blade knife 7 cuts the soil with sliding and, according to [Klenin N.I., Sakun V.A. Agricultural and reclamation machines - M.: Kolos, 1994. - C 40], without the formation of a compacted soil core in front of the blade, which reduces energy consumption.

The side surface of the lamellar knife 7 rests on the dense side wall of the slot and, like the field board of the plow body, compensates for the lateral component of the transverse forces acting on the tool on the slope, ensuring movement stability. When calculating the required area of the lateral surface of the knife 7, the method for calculating the field board of the plow body, set out in [3, C.84…85], is used.

In the case of rains, the slots formed by the knife 7 contribute to a better accumulation of surface water infiltration into the soil, reducing the process of water erosion on the slopes.

Thus, the claimed technical result is achieved.
