TILLAGE TOOL Russian patent published in 2024 - IPC A01B35/20 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular to devices of working members of tillage machines for main (continuous) surface treatment of soil, and can be used to reduce traction resistance during deep tillage of soils saturated with plant and root residues, including on weakly stony and medium-stony soils with specific resistance of up to 0.09 MPa (0.9 kgf/cm²). Tillage tool comprises frame (1) with support wheels (2), working members (3) for soil layer loosening in the form of flat-cutting blades, resilient element (4) with stiffness adjustment mechanism, providing possibility of working members oscillations in longitudinal plane, guides (6) in form of channel, fixed to frame (1) on bolts (5), inside guides (6) with possibility of movement in longitudinal direction there are axes (7 and 8), at the ends of which there are rollers (9) and rolling bearings (10), rolling bearings (11) are installed in the middle of axes (7 and 8), between which there is post (12). Upper part of post (12) has a front working surface in the form of an oblique cut, the working zone of which is located at angle of 13 degrees to the vertical, and the rear part has a curved working surface in the form of a hyperbolic curve, on axes (7 and 8) rods (13 and 14) are hinged, on which resilient elements (15 and 16) are movably installed, having different stiffness, made in the form of cylindrical compression springs, resting against stop (17) rigidly fixed on the frame, and inner ends of resilient elements are fixed on rods by nuts (18 and 19).

EFFECT: improving reliability, efficiency, reducing traction resistance and energy consumption during treatment of soils of different mechanical composition, as well as medium-stony soils due to increased functional capabilities of chisel deep tiller and new design of its structural elements and assemblies.
