TILLAGE INSTRUMENT Russian patent published in 2010 - IPC A01B21/00 

FIELD: agriculture.

SUBSTANCE: instrument contains a frame, which has consistently set rotary cultivators. Each rotary cultivator is formed as a shaft placed perpendicular to the direction of motion with a spiral-plate working body with teeth. The working body is fixed on the ends of the shaft by means of elastic elements, radially mounted on the flange. Shafts are interlinked by means of chain drive and have the tool to limit penetration of working bodies. The working surface of the spiral-plate working body is made of corrugated (wavy) in the form of turbodisks surface. The cutting edge of the working body has a wavy contour formed with smoothly conjugated arcs, placed along a helical line and perpendicular to the direction of motion of the shaft. Worktop of ripper in the area of its summit is close to the shaft and has a generatrix located in the vertical plane to the longitudinal axis of the shaft and copies the wavy contour of the cutting edge. A shape of a working surface of the working organ is formed by the movement of a streight line along wavy curve: with one end of the streight line placed along the contour of the cutting edge, and the other end - on the generatrix, located in the zone of its vertices.

EFFECT: constructive implementation will improve the quality of soil due to its intensive crumbling and reduce the energy consumption of the process of soil loosening.
