ADAPTIVE SUBSOILER FOR COMPACTED FLAT AND SLOPING SOILS Russian patent published in 2023 - IPC A01B13/14 

FIELD: agricultural machinery.

SUBSTANCE: subsoiler comprises a frame with rippers racks located on it with nares and soil lifters fixed on the side faces. The subsoiler racks are pivotally mounted on the frame with the possibility of rotation around the vertical axis of the racks and changing the angle of inclination of the rack along the profile. A flat cylindrical controlled hinge is installed in the corner of the "V"-shaped frame of the subsoiler, the longitudinal axis of which is perpendicular to the common horizontal. A flat cylindrical controlled hinge is installed in the fracture of the subsoiler rack, the longitudinal axis of which is located in the common horizontal, perpendicular to the frontal projection of the rack deformer system. A controlled hinge is integrated into the attachment point of the soil lifters, which provides a change in the angle of inclination of the soil lifters.

EFFECT: increased efficiency of processing compacted flat and sloping lands without seam turnover due to adaptation to possible changes in the processing environment, which will allow, without stopping the loosening process, to stabilize the load on the working bodies and the drive of the traction machine.
