COUPLING WEIGHT LOAD-DISTRIBUTING DEVICE OF HEAVY DISK HARROW Russian patent published in 2018 - IPC A01B23/00 A01B21/08 A01B63/11 A01B63/112 A01B63/114 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building, in particular to additional assisting devices for distributing the coupling weight between the coupling implement and the power means. Coupling weight load-distributing device of a heavy disc harrow comprises a power hydraulic cylinder mounted in a corner bracket with a power hinge fixed in a hinge support on the upper front part of the harrow frame. In the upper power hinge of the angle bracket and the rear support hinge bracket, the equalizing rod is fixed with the endings. Torsion axle passes through the fork of the power cylinder and a harrow built between the crossmembers of the harrow.

EFFECT: increase in traction and coupling properties of the towing power means is provided, reduction of mass and metal consumption of the agricultural machine structure, alignment of vertical loads on the harrow sections, decrease in total energy costs of AIT in operation, improvement of the quality of presowing treatment with a harrow disk heavy and convenience in its operation with a fairly simple design of the assisting device, simplicity of its manufacture, high reliability, ease of maintenance and operation.
