WIDE-CUT TILLAGE TOOL Russian patent published in 2012 - IPC A01B59/04 A01B73/00 

FIELD: agriculture.

SUBSTANCE: instrument contains a needle, a frame consisting of a pivotally connected central and two side sections with working bodies. The side sections are made hinged due to connection with the hydraulic cylinders. The central and side sections are connected by a connecting link in the form of the beveled crankshaft. The beveled neck of the crankshaft is located at 45° to the crank journals. The beveled neck of the crankshaft of the connecting link is pivotally placed in the supports mounted to the central section of the frame so that the axes of the supports form with the plane of the frame an angle 45. The crank journals of each connecting link are pivotally placed in the supports mounted on a respective side frame section so that in the working position of the tool their centerlines are parallel to the longitudinal axis of the tool. The supports of the beveled neck and the crank journals and in working and in transport positions the tools are located in the same longitudinal vertical plane. On the surface of the beveled neck of the connecting link a thrust is made.

EFFECT: constructive implementation enables to simplify the design of wide-cut tillage tool, as well as to reduce the time of transfer of sections from transport to working position and vice versa.
