TOOLS FOR SOIL LAY-DOWN Russian patent published in 2017 - IPC A01B29/04 

FIELD: agriculture.

SUBSTANCE: tool for soil lay-down contains a set each other on the frame on the axes of rollers. Rollers are formed as cylinders of the same diameter, mounted on axles which are arranged along the longitudinal axis of symmetry of the cylinder. On both sides of the cylinder, the holes are arranged in staggered rows. At the ends of the axes of the cylinders protruding from one side of the same diameter mounted sprocket coupled circuit. When rotating rollers of projection holes, in contact with the soil surface, the second roller on the same soil region are located between the projections of the first roller holes. The diameter of the holes is less than the maximum agronomic requirements of the size of the soil clods. Inside each cylinder on the axis radially and leashes are pivotally mounted at their ends in the direction of movement of rollers mounted sickle hammers so that the distance decreases in the direction of rotation of rollers between their outer surface and the inner surface of the cylinder 5 cm 0.25…10 mm.

EFFECT: invention provides the improved quality of compacting the soil and breaking the soil lumps.
