WORKING ELEMENT OF TILLAGE TOOL Russian patent published in 2024 - IPC A01B13/14 

FIELD: agriculture.

SUBSTANCE: invention relates to tools for main (winter) tillage and can be used in agriculture. Working element of the tillage tool consists of stilt 1, with shoe 2 welded in the lower part with overhead chisel 3. Along stilt 1 holes 4 are drilled, in which through inserted bushings pair of bolts is fixed movable pair of undercutting lugs 5. Both bushings have eccentric displacement of holes and are installed mirror-like relative to vertical axis of holes 4 on stilt 1 with horizontal location of eccentric displacement. Holes 7 in undercutting lugs 5 are made at a distance that provides assembly of the group: stilt 1, bushing, bolt, lug 5. When installing the upper bushing into hole 4 of stilt 1 with the hole eccentric displacement backwards, and the lower bushing with the hole eccentric displacement forward, lug 5 crumbling angle is formed, equal to 10–12 degrees, and at mirror change of position of bushings, crumbling angle of lug 5 is equal to 25–27 degrees.

EFFECT: reducing the number of structural elements and simplifying the design of the working element of the tillage tool.
