WORKING BODY FOR TILLAGE WITH SAFETY DEVICE Russian patent published in 2022 - IPC A01B35/22 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to soil-cultivating working bodies. The working body for tillage with a safety device contains a stand (1) with a chisel (2). A horizontal knife (3) is mounted on the rack (1) by means of a vertical hinge, and a vertical plate (5) is rigidly fixed on the axis (4) of the vertical hinge. Between the mounting plates (6), (7) of the vertical hinge on its axis (4), both the vertical movement limiter (8) resting on the lower mounting plate (6) of the vertical hinge, and the vertical-horizontal movement limiter, made in in the form of a vertical plate (5), at the end of which a ring is rigidly fixed with the possibility of its interaction with the rack (1), while the width of the vertical plate (5) is less than the height of the ring, and holes (9) are made on the upper mounting plate (7) of the vertical hinge with the possibility of installing in them the lower hook of the torsion spring (10), the upper hook of which is installed in the hole of the upper end of the axis (4) of the vertical hinge. The cutting edge (11) of the horizontal knife (3) is made along an arc of a circle of radius R1, which is conjugated through an arc of a circle of radius R2 with the center coinciding with the center of the axis (4) of the vertical hinge, and with the side surface (12) of the horizontal knife (3). Chamfers (13) are made at the ends of the mounting plates (6), (7) of the vertical hinge and the vertical plate (5).

EFFECT: increased reliability of the working body.
