WIDE-CUT SOIL-CULTIVATING FOLDING MODULE Russian patent published in 2017 - IPC A01B59/42 

FIELD: agriculture.

SUBSTANCE: wide-cut soil-cultivating folding module includes a frame made of tubes, with a trailing device. The frame is supported in the rear part by two pneumatic wheels. On the rear tube of the frame, the middle swivel bar is movably mounted. The swing bar is fixed to the frame by means of two hydraulic cylinders. The brackets are rigidly fixed on the middle swivel bar. At the butts of the middle swivel bar, through swivel joints made in the form of cardan joints, side swivel bars are installed. Impellers are installed at the opposite butts of the swivel bars. Transport wheels installed at an angle inward in the unit movement direction are mounted on the front walls of the swivel bars. The extreme ends of the side swivel bars are connected to the front frame part by tie-rods. The tie-rods consist of 2 parts: the front ones, which are short, and the rear ones, which are long. The front tie-rods are rigidly fixed to the frame at one end, and catchers and latches are mounted at the second end. The latch mobility is limited by springs mounted on the fingers. The rear tie-rods are movably connected in front with U-shaped arms, which are movably installed by their second ends on the frame. At the rear, the tie-rods are movably fixed on the side swivel bars. The inner ends of the latches by means of cables through the compensation springs with limiters are connected to the middle swivel bar. The transport wheels are mounted on the front walls of the side swivel bars by means of brackets. The brackets consist of fixed parts - housings - and racks movably mounted therein. Axles with hubs of the transport wheels are mounted on the racks. The racks of the transport wheels in the housings are fixed by hydraulic cylinders through levers. The levers are rigidly fixed on the racks. The hydraulic cylinders through hydraulic hoses are connected to the hydraulic tractor system, by means of which the angle of convergence of the transport wheels installation varies from 0° to 45° towards the side swivel bars.

EFFECT: reducing the unit path through the field when it is transferred from the transport position to the working position and back due to increasing the angle of convergence of the transport wheels rotation.
