ENERGY SAVING TILLAGE RACK Russian patent published in 2013 - IPC A01B35/20 A01B39/20 

FIELD: agriculture.

SUBSTANCE: rack comprises a front and a rear contours. The front contour of the rack is formed by two or more overlapping segments of cycloids. Maximum angles of descent to the trajectory of each pair of segments of cycloids at their points of intersection do not exceed the angle of soil friction on metal. When implementation of the front contour of the rack, formed by more than two segments of cycloids, the front contour of the rack has serrated profiles on height. The angle between the straight line connecting the point of intersection of adjacent segments of cycloids is smaller than the angle φ of the soil friction to metal by an amount equal to half the angles of descent to the segment of each of the cycloid, covering half of its segment. The rack height is proportional to the depth of tillage. Number of segments of cycloids increases with increase of depth of tillage. The rack on the rear contour has brackets, hinges and a rod.

EFFECT: constructive implementation enables to reduce energy costs and to increase environmental safety and quality of soil treatment and, as a result, crop yield.
