SUBSOILER Russian patent published in 2023 - IPC A01B13/08 

FIELD: agricultural engineering.

SUBSTANCE: invention to tillage working bodies for deep loosening of the soil. The subsoiler contains a stand with a front wedge-shaped edge, a chisel located in the lower part of the stand, having a cutting edge made in the shape of a logarithmic curve with the opposite convex curvature to the subsoiler stand, with three peaks and two depressions, rigidly attached to the stand. On the front wedge-shaped face of the stand, in a longitudinal-vertical plane with an overhang equal to half the diameter of the disks, disc-shaped disks for cutting the soil are installed, rigidly fixed by means of a bolted connection. The cutting edge of the disc discs is made with notches. The stand is made with a bend directed towards the forward projection at the bottom of the stand in the direction of travel of the machine. In this case, at the place where the post is bent, there is a protrusion to which a chisel is attached, similar to the chisel attached to the bottom of the post. Additionally, knives are fixed at the same level with the upper and lower chisels, forming a flat-cut paw together with the chisel. The cutting edge of the knives is made in the form of a logarithmic curve.

EFFECT: use of the invention will improve the quality of soil loosening over the entire cross-sectional area of the treated formation.
