Description

The utility model refers to the working bodies for the main tillage implements and can be used in agriculture.

Known working body of a chisel plow, containing a frame with racks mounted on it, each of which has a shoe with an overhead chisel (catalog of agricultural machinery. - Volume 1. - M .: Informagrotekh. 1991. - S. 140).

The technical disadvantage of the tool with these working bodies is the low quality of soil cultivation due to the impossibility of adapting to specific soil and climatic conditions, which limits its use.

Known working body of a chisel plow, consisting of a stand with a shoe welded in the lower part with an overhead chisel attached to it with bolts, holes are drilled along the stand, to which movable undercut wings can be attached, which are made with a bent end corresponding to the profile of the stand and are bolted together, not protruding beyond the projection of the rear part, and the other connection is located in the area of the closed cutting part (RU 2487514 C1, 07.02.2012).

The technical disadvantage of such devices: the complexity of manufacture and irrational pattern of the replaceable element - the undercut wing.

The closest device to the declared working body of a tillage tool is a working body 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 undercut wings are attached with a pair of bolts, consisting of a blade and a shank with mounting holes and bent upwards along the line corresponding to the angle of soil crumbling (RU PM No. 148330 U1, 10.12.2014 Bull. No. 34).

The technical disadvantage of this working body is the overhang of root residues and weeds at the point of attachment of the shank with the stand, which reduces the operational and technological parameters of the tillage tool.

Task: reducing the overhang of root residues and weeds on the working bodies of the tillage implement at the point of attachment of the shank with the tine.

EFFECT: increased operational and technological performance of the tillage machine-tractor unit.

The claimed technical result is achieved by the fact that the working body of the tillage tool consists of a stand, in the lower part of which a shoe with a fixed overhead chisel is welded. Holes are drilled along the rack through which movable undercut wings are attached with a pair of bolts, consisting of a blade and a shank with mounting holes, bent along a line corresponding to the crumbling angle of the soil, and down.

The figure shows the stand of the cultivator working body.

The working body of the tillage tool contains a stand 1 with a shoe 2 welded in the lower part with a fixed chisel 3. Along the stand, holes 5 are drilled through which a pair of undercut wings is fastened with a pair of bolts 5. The undercut wings consist of a blade 6 and a shank 7 with mounting holes. The shank 7, relative to the blade 6, is bent downward along the line corresponding to the soil crumbling angle β, equal to 15-18 °.

The technological process of the work of the working body of the tillage tool is reduced to loosening the soil with a chisel 3, followed by processing with a cutting wing from cutting with a blade 6 forming a crumbling angle β. The depth of tillage from the chisel is regulated by the support wheels of the tillage implement, and in the undercutting wings, by rearranging them along the holes 5 along the rack 1.

When loosening the soil, the encountered root residues and weeds with strut 1 move upward along the strut, from denser soil to looser one. If the shank 7 is bent upward relative to the blade 6, then the front bending line of the undercut wing, at the point of attachment with the strut 1, forms a wedge angle, which causes overhang of root residues and weeds. If the shank 7 is bent down, then the root residues and weeds descend along the bend radius of the undercut wing or rises up the strut.

Such a design of the working body of the tillage tool provides a decrease in the overhang of root residues and weeds on the working bodies of the tillage tool, which increases the operational and technological performance of the tillage machine-tractor unit.

Claims (1)

The working body of the tillage implement, consisting of a stand, in the lower part of which a shoe with a fixed overhead chisel is welded, holes are drilled along the stand through which movable undercut wings are fixed with a pair of bolts, consisting of a blade and a shank with mounting holes, bent along a line corresponding to the crumbling angle soil, characterized in that the shank, relative to the blade, is bent down along the line corresponding to the angle of soil crumbling β, while the crumbling angle is 15-18 °.
