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 ribs evenly spaced around the circumference, mounted along a helical line connecting vertical disks. 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 axis mounted in bearings on leashes 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. On the axis of the hollow cylinder, sprockets are rigidly installed between the vertical disks at an equal distance from them. On the surface of the smooth cylinder, annular grooves are made with sprockets installed inside them, the outer diameter of which does not exceed the outer diameter of the smooth cylinder. The sprockets mounted on the axis of the hollow cylinder and the sprockets of the smooth cylinder are connected to each other by chains, and debalancers are installed on the axis of the hollow cylinder.

EFFECT: invention provides an increase in the quality of soil rolling and crumbling of soil lumps.
