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

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to tillage rollers. The tillage roller includes a hollow cylinder equipped with an axis with evenly located ribs around the circumference. The ribs are installed in a helical line and connect the vertical disks. Inside the hollow cylinder, a smooth cylinder is installed, the diameter of which is less than the radius of the hollow cylinder. The smooth cylinder is provided with an axis mounted in bearings on tangs on the axis of the hollow cylinder. The axis of the hollow cylinder is installed with the possibility of rotation separately from the vertical disks. Pulleys are rigidly mounted on the axis of the hollow cylinder. On the surface of the smooth cylinder, an annular groove is made in its center, connected by a belt to a pulley. The dimensions of the cross-section of the annular groove are equal to the dimensions of the cross-section 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 it in a given position, elliptical-shaped debalancers are installed. The diameter of the pulley is made smaller than the inner diameter of the annular groove.

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