INTERROW EROSION PREVENTIVE CULTIVATOR Russian patent published in 1996 - IPC

FIELD: agricultural engineering. SUBSTANCE: cultivator has goose-foot share 3 and flat hoes 6, which loosen tilled crop spacings for predetermined depth and remove weeds, and convex- convex elliptical disks 9 mounted on rotary shaft at an angle of "alpha" with respect to it. Disks are rotated about geometrical axes to form sinusoidal furrows in spacings in horizontal and vertical planes. Soil relief is traced by each independent working section of disks 9 due to flexible couplings. Larger axes of disks 9 are turned counterclockwise for an angle of "beta" one with respect to the other to balance side and lateral forces. Sinusoidal furrows provide improved flow and washing away resistance due to curved configuration of furrows in two planes, which causes water to flow from one plane to the other with reducing flow rate. As a result efficient settling down of soil layers and prolonged water absorption are provided. EFFECT: increased efficiency and improved quality of tilled soil. 3 dwg
