TILLAGE ROLLER Russian patent published in 2021 - IPC A01B29/00 A01B29/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural engineering, in particular to tillage rollers. The tillage roller includes a hollow cylinder equipped with an axis with evenly spaced 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 fitted 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, and annular grooves are made on the surface of the smooth cylinder, connected by belts to the pulleys. Actually, the dimensions of the cross-section of the annular grooves are equal to the dimensions of the cross-section of the belt. On the axis of the hollow cylinder at an equal distance from each other, the debalancers are installed.

EFFECT: invention makes it possible to improve the quality of soil rolling and crumbling of soil lumps.
