SECTION OF TILLAGE MACHINE WITH ADJUSTABLE LOCKING DEVICE FOR PROCESSING ROCKY SOILS Russian patent published in 2023 - IPC A01B35/22 A01B61/04 

FIELD: agriculture.

SUBSTANCE: section of a tillage machine with an adjustable fuse for processing rocky soils contains a working body with a stand attached to the frame using a hinge and held in working position by a power element of the fuse with a movable roller. The fuse is connected to the movable roller by means of a cable wound around its surface, made in the form of truncated cones with spirally formed flanges or grooves for laying the turns of its branches with the possibility of adjusting the force and stroke of the power element and the characteristics of the increase in force of the fuse during its operation due to changes in the positions of the cable branches relative to the conical surfaces of the movable roller, accompanied by a decrease in the torque from the action of the power element during the operation of the fuse. The movable roller is connected through an axis and a height-adjustable rod to the front arm of the working body rack, and the free end of the cable is fixed to the frame.

EFFECT: reduction in the metal consumption of the section, reduction in energy consumption in the process of bypassing stones with an improvement in the quality of tillage, the accuracy of adjustment to different soil backgrounds due to the possibility of adjusting the force and stroke of the power element and reducing the characteristics of the increase in force of the safety mechanism during its operation.
