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 fields with multiple areas of compacted soils, which do not allow atmospheric precipitation moisture to pass through. 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 (3) oscillations in longitudinal plane, guides (6) in form of channel, fixed to frame (1) on bolts (5), inside guides (6) on axis (9) rigidly fixed on post (10) of working member (3), with possibility of movement in longitudinal direction there are rollers (7) with rolling bearings (8). Rear part of post (10) has recess (11) equal to half the diameter of bearing (12), and oblique cut (13), the working area of which is located at angle of 13 degrees to vertical, with which it rests against bearing (12) installed on movable axis (14), on which rollers (7) with rolling bearings (8) are located. On axis (14) rod (15) is hinged, on which there installed is resilient element (4) in the form of cylindrical compression spring resting against stop (16). Nut (17) is installed on rod (15), which performs function of stiffness adjustment of resilient element (4), limiter of movement of post (10) of working element (3).

EFFECT: increased reliability, efficiency, reduced traction resistance and power consumption at treatment of soils of different mechanical composition due to increased functional capabilities of chisel subsoiler and new design of its structural elements and assemblies.
