Description

The utility model relates to agricultural engineering, in particular to the working bodies of implements for basic tillage.

Known working body tillage tools [Author's certificate RU patent No. 148330, IPC class. А01В 13/14, 2014], consisting of a stand with a shoe welded in the lower part, with an overhead chisel, holes are drilled along the stand, through which movable cutting wings are attached with a pair of bolts, consisting of a blade and a shank with mounting holes and bent up along the line, corresponding to the crumbling angle of the soil.

The technical disadvantage of this working body is the overhanging of root residues and weeds at the point of attachment of the shank with the stand, inability to cultivate soils subject to wind erosion, which reduces the operational and technological performance of the tillage tool.

The closest analogue to the claimed is the working body of the tillage tool [Author's certificate RU patent No. 204465, IPC class. А01В 13/14, 2021], consisting of a post, in the lower part of which a shoe with a fixed overhead chisel is welded, holes are drilled along the post, through which movable cutting wings are fixed with a pair of bolts, consisting of a blade and a shank with mounting holes, bent down relative to the blade along the line corresponding to the soil crumbling angle β equal to 15-18°.

The disadvantages of this design are:

- lack of technological possibility of cutting the roots of weeds and loosening the top layer of soil in areas subject to wind erosion without throwing wet soil to the surface and without falling asleep on the surface of plant residues;

- the inability to adjust the angle of installation of the undercutting wings in the plane of the angle of crumbling when processing soils with different mechanical composition, which leads to an increase in energy consumption and a decrease in the quality of work.

The technical result of the utility model is the expansion of technological capabilities while reducing energy consumption and improving the quality of work.

The technical result is achieved due to the fact that the shank with mounting holes is bent relative to the blade along the 90° line, the holes in the rack are oblong, made along an arc of a circle of the same radius and have the same length to allow fastening of the cutting wings in various positions, both along the height of the rack , and with different crumbling angle β within 0…20°.

The specified set of essential features ensures the appearance of the proposed working body of the tillage tool 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 the device of the working body of a tillage tool, side view.

The working body of the soil-cultivating tool, consisting of a rack 2, in the lower part of which a shoe 7 is welded with a fixed overhead chisel 1, holes are drilled along the rack 2, through which movable cutting wings are fixed with a pair of bolts 6, consisting of a blade 5 and a shank 4 with mounting holes, bent relative to the blade, and the shank 4 with the mounting holes is bent relative to the blade along the line 90°, the holes 3 in the rack are oblong, made along an arc of a circle of the same radius and have such the same length to provide the possibility of fastening the cutting wings in different positions, both along the height of the rack 2 , and with different crumbling angle β within 0…20°.

The working body of the tillage tool works as follows.

Before processing soils that are not subject to erosion processes, depending on the specified processing depth, texture and soil moisture, the cutting wings on the stand 2 are set in such a position in height and angle β of the blade 5 to ensure maximum crumbling of the soil with the lowest energy consumption.

In this version, when the working body moves in the soil, the chisel 1 and the rack 2 destroy the bonds of soil aggregates by propagating cracks in the longitudinal and transverse planes according to [3, p. 125…128]. In this case, large lumpy aggregates are formed. The soil layer above the cutting wings is crushed into smaller aggregates by blades 5 set at an angle equal to the angle of friction of the given soil against steel, and working according to the wedge principle described in [3, p. 31…35], depending on the mechanical composition and soil moisture.

Before processing soils subject to wind erosion, the cutting wings are mounted on a rack in such a position in height and angle of inclination of the blade 5 that they work according to the principle of the paw of a cultivator-flat cutter or flat cutter-subsoiler, set out in [3, p. 116…119].

Thus, the possibility of technological use of the working body is expanded, the quality of work is improved and energy consumption is reduced.
