TILLAGE DEVICE Russian patent published in 2023 - IPC A01B35/22 A01B63/24 

FIELD: agriculture.

SUBSTANCE: soil-cultivating tool contains 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 (11 and 12) with a stiffness control mechanism that provides the possibility of oscillation of the working bodies (3) in the longitudinal planes. Guides (6) 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, mounted on axles, which are rigidly fixed to the rack (10) of the working body (3), with the possibility of moving in the longitudinal direction. The upper part of the rack (10) is located between the elastic elements (11 and 12) having different stiffness and made in the form of cylindrical compression springs mounted movably on the rod. The inner ends of the elastic elements (11 and 12) are fixed with nuts. The stem with its middle part is pivotally bolted to the top of the rack (10). The outer ends of the elastic elements (11 and 12) abut against the stops rigidly fixed to the frame (1).

EFFECT: increase in productivity, reduction in traction resistance and energy costs, as well as a significant improvement in pre-sowing soil preparation in accordance with agrotechnical requirements.
