WORKING BODY OF THE TOOL FOR TILLAGE Russian patent published in 2022 - IPC A01B13/08 A01B39/20 A01B15/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The working body of the tillage tool consists of a rack (1) with a shoe welded at the bottom (2) with an attached overhead chisel (3). Holes are drilled along the rack (1), through which a pair of bolts are fixed with a movable pair of trimming wings (4). The rear part of the trimming wings (4) is made with a corrugation cone (5) sinusoidal in diametric cross-section. The guiding axis of the corrugation cone (5) faces the blade (6) of the trimming wings (4) and the direction of the axis of the corrugation cone (5) does not coincide with the direction of movement of the working body and with the axial longitudinal line of the rack (1). The projection of the lower edge of the corrugation cone (5) in the vertical plane does not go beyond the horizontal-longitudinal the plane of the cutting line of a pair of wings (4). The top of the corrugation cone (5) is located above the cutting line of the arm.

EFFECT: quality of cultivation is improved with a decrease in erosion processes during tillage.
