COMBINED TILLAGE EQUIPMENT Russian patent published in 2008 - IPC A01B7/00 

FIELD: agriculture.

SUBSTANCE: combined tillage equipment consists of the frame, tractor hookup, operating elements mounted on the frame in two rows, packing and leveling devices and concave disks on the horizontal axis behind the operating elements. The operating elements of the second row are shifted horizontally against the operating elements of the first row. Each operating element is made in the form of free running tine with the concave disk with its camber facing upwards. The concave disk of the operating element is fixed transversely to the tine; its all round cutting edge is located in horizontal plane. The concave disks are mounted on the horizontal axis pairwise at an angle to each other; besides, the disks in each pair are mounted with their cambers towards centre of symmetry. The centre of symmetry of each pair of disks is located in the same lengthwise-vertical plane with the corresponding tide of the first row operating elements. The packing and leveling device is made in the form of the assembly consisting of packing wheels located one by one. The tides of the operating elements are mounted on the frame via safety guard. The operating elements of the second row are mounted with overlapping of the operating elements of the first row. Each pair of the height adjustable concave disks on the horizontal plane is mounted on the frame. The frontal packing wheel of the assembly is cannulate and the backward one is slatted, moreover it is possible to turn the backward packing wheel through a full 180 degrees. The equipment will allow increasing tillage quality and grain yield.

EFFECT: increase of the tillage quality and grain yield.
