TILLAGE ROLLER Russian patent published in 2021 - IPC A01B29/04 

FIELD: agricultural machinery.

SUBSTANCE: invention relates to agricultural machinery, in particular to tillage rollers. The tillage roller includes a hollow cylinder equipped with an axis with ribs evenly spaced around the circumference, installed along a helical line, connecting the vertical discs. A smooth cylinder is installed inside the hollow cylinder, the diameter of which is less than the radius of the hollow cylinder. The smooth cylinder is equipped with an axle mounted in bearings on leashes on the axle of the hollow cylinder. The axis of the hollow cylinder is rotatably mounted separately from the vertical discs. A pulley is rigidly mounted on the axis of the hollow cylinder. An annular groove is made on the surface of a smooth cylinder along its center, connected by a belt to a pulley. The cross-sectional dimensions of the annular groove are equal to the cross-sectional dimensions of the belt. On the axis of the hollow cylinder with the possibility of changing its position relative to the axis of the hollow cylinder and fixing in a given position, unbalancers are installed, made in the form of bushings, on the outer surface of which rods are radially mounted with weighting agents fixed at their ends. The pulley diameter is made smaller than the inner diameter of the annular groove.

EFFECT: invention improves the quality of soil compaction and crumbling of soil lumps.
