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. Sprockets are rigidly installed on the axis of the hollow cylinder between the vertical disks and at an equal distance from them. On the surface of a smooth cylinder in the same plane with the sprockets installed on the axis, annular grooves are made with sprockets installed inside, 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. Debalancers are installed on the axis of the hollow cylinder. The number of teeth installed inside the annular grooves of the sprockets is at least twice the number of teeth of the sprockets installed on the axis of the hollow cylinder.

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