SOIL TREATMENT DEVICE Russian patent published in 2020 - IPC A01B11/00 A01B35/28 A01B29/04 A01B33/02 A01B33/14 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Device for soil treatment comprises working member in form of bores (1) and its drive. Each of bores (1) contains rod with screw (3). Rod comprises working part (4) and spring-loaded part (5) of equal size. On the upper end of bore stem (1) there is pressure ball (6) and thrust washer (7). Free spring (8) is freely arranged on spring-loaded part (5) of the rod. On body of working part (4) of bore (1) there is screw thread. Body of working part (4) of bore (1) is arranged on thread made in end channel of guide of cylindrical bushing (9) arranged coaxially in threaded bushing (10) and rigidly connected to it. Threaded bushing (10) contains screw thread on external surface. Inner hole of threaded bushing (10) is connected with axial hole of working bushing (9) and corresponds to dimensions of screw (3). Threaded bushing (10) is placed on the thread in the through circular hole made in the body of the drum. Containing adjacent rifled bushings (10) are arranged on thread in through round holes made in body of drum, and are located in longitudinal rows at distance from each other at distance 1/2 of hole radius. Drum is made of solid material, for example, cast iron or steel. Caps are attached to the ends of the drum by means of bolts, which contain in the centre round holes with bearings in them, in which trunnions are arranged. Entire length of the axis comprises a horizontal tide in the form of a plate, the size of which is smaller than the radius of the inner circumference of the drum by the length of screw (3), and a vertical tide perpendicular to it, the size of which is smaller than the radius of the inner circumference of the drum by the length of the working part of screw (3). Pushing shoe in the form of a plate curved in the form of a curve of the second order is attached to the tides by adjusting rods.

EFFECT: creation of optimum conditions for germination of seeds, reduction of energy intensity, minimization of presowing soil preparation, reduction of erosion hazard and simplification of design.
