REVERSIBLE PLOUGH Russian patent published in 2025 - IPC A01B3/46 A01B15/00 A01B63/16 

FIELD: agriculture.

SUBSTANCE: reversible plough has a coupling on which a frame is hinged, which, in its turn, carries at least one pair of opposite ploughing elements. Reversible plough has an overturning cylinder between the frame and the hitch to turn the frame relative to the hitch between two working positions of ploughing from the positioning stage on one side of the plough to the stage of repositioning on the opposite side with passage through the position of the turning cylinder dead point. On the plough frame, there is a support wheel for adjusting its working depth, made with possibility of turning over together with the frame for adjusting the plough working depth in both turning positions on opposite sides of the plough frame and with possibility of locking in working position by means of locking hydraulic cylinder, having pressure chamber, which is selectively hydraulically connected to turning cylinder and/or levelling cylinder by means of control valve. Control valve is configured to be connected to the pressure chamber for release during the plough turning step by the overturning cylinder and to create pressure in the chamber when the overturning cylinder and/or the levelling cylinder performs/performs or has completed the repositioning step. Locking hydraulic cylinder is configured to provide orientation of support wheel during plough turning and locking of support wheel orientation, when plough assumes working position of ploughing, in which locking hydraulic cylinder is connected on one side with plough frame, and on other side, with support of support wheel installed on frame with possibility of rotation between two positions of rotation on opposite sides of frame.

EFFECT: simplified design, prevention of incorrect position of the wheel support with ensuring correct wheel alignment and wheel positioning, as well as installation of the wheel in the transport position and prevention of premature wear of the wheel support.
