UNIVERSAL MULTI-OPERATION TILLAGE DEVICE Russian patent published in 2023 - IPC A01B35/20 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, and in particular to the working bodies of tillage machines. The universal multi-operation tillage device consists of a holder, two wings, an overlay for a ripper. The lining is made double in the form of identical halves connected to each other in the front part, copying the upper and lower surfaces of the cultivator paw along the butt line of the wings and the holder. The lower part of the lining is made with grooves for the slot and with a limiter at the end. The length of the grooves is at least not greater than the length of the foot base. The length of both halves of the lining is equal to the sum of the lengths of the paw base along the butt line and the holder. The distance between the two halves of the lining is at least not less than the thickness of the paw wings. The upper and lower halves of the lining and the paw holder are rigidly fixed on the rack with common countersunk bolts. The thickness of each half of the lining is half the thickness of the paw wings, and the paw wings are oval in shape.

EFFECT: invention will improve the quality of tillage, stability of the course and reduce the traction resistance of the tillage device.
