DISTRIBUTING-LOADING DEVICE FOR TRAILED FRAME DISC HARROW Russian patent published in 2024 - IPC A01B21/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, namely to distributing and loading devices for trailed frame disc harrow. Device is made in the form of a structure consisting of a power hydraulic cylinder, a transmitting rod, a distributing rod and a rod spring. Power hydraulic cylinder is installed in angle bracket with power hinge, which is fixed in hinged support on upper front part of harrow frame. Transmitting rod is made in the form of a flat leaf spring fixed by dynamic deflection upwards and fixed by its ends in the power hinge of the angle bracket and the rear support hinge bracket. Distributing rod is made in the form of a flat leaf spring with dynamic upward deflection, installed by the ends between the spring-loaded loading brackets located from above by the board in the rear front part of the harrow frame, and is fixed in the central part through the process hole by bolting in the rear support hinge bracket. Rod spring passes through the forked working part of the power hydraulic cylinder and is built-in between the crossbars of the lower part of the harrow.

EFFECT: invention will make it possible to provide an increase in the towing power facility traction-adhesion properties, reduction of the machine-tractor unit (MTU) power consumption, reduction of slippage, improved quality of pre-sowing treatment with a trailed frame disc harrow and ease of use.
