TILLAGE DEVICE Russian patent published in 2023 - IPC A01B35/06 

FIELD: agricultural engineering.

SUBSTANCE: soil-cultivating tool comprises a frame (1) with support wheels (2), working bodies (3) for loosening the soil layer in the form of flat-cutting blades, an elastic element (4) with a stiffness control mechanism that provides the possibility of oscillation of the working bodies in the longitudinal planes. Guides in the form of a channel are fixed to the frame (1) by means of bolts, inside of which two rollers with rolling bearings are located. The rollers are mounted on axles, which are rigidly fixed on the rack (10) of the working body. The upper part of the rack (10) is connected to the rod by a bolted connection, fixed on the frame (1) in the stop by means of a nut. An elastic element (4) in the form of a cylindrical compression spring is installed between the washers.

EFFECT: increase in productivity, reduction in traction resistance and energy costs, as well as an improvement in soil preparation in accordance with agrotechnical requirements.
