WORKING TOOL OF TILLER Russian patent published in 2018 - IPC A01B13/14 A01B35/22 

FIELD: agriculture; machine building.

SUBSTANCE: invention refers to agricultural engineering industry, namely to working elements for underwinter surface tillage tools. Working organ of the tillage tool consists of stand (1) with a block with an attachable chisel welded in the bottom part. Along strut (1) holes are drilled, through which a pair of trimming wings (3) is fastened by a pair of bolts (2). One of the holes of the pair of trimming wings (3) is made in the form of polyhedron (4), into which is inserted bushing (5) with an eccentric displacement and also having the shape of a polyhedron. Number of facets of a polyhedron is equal to twice the difference in the required number of fixed settings, reduced by one. Opposite hole of cutting wing is made in the form of vertical slot (6), providing rotation of eccentric for the required angle. For an equal set angle of crushing of legs (3), bushings (5) of polyhedra (4) are set to an equal face.

EFFECT: such a constructive implementation of the working organs of the soil-cultivating tools is aimed at increasing operational and technological and energy indicators.
