TILLAGE ROLLER Russian patent published in 2017 - IPC A01B29/04 

FIELD: construction.

SUBSTANCE: tillage roller comprises a hollow cylinder with ribs evenly spaced around the circumference. The ribs are installed along a helical line and connect the vertical discs. The hollow cylinder is provided with an axis on which leads are mounted radially and pivotally. At the ends of leads, hammers made in the form of two cylinders symmetrically arranged relative to the hinge are pivotally mounted parallel to the axis. The diameter of the cylinders is less than the radius of the hollow cylinder. The distance between adjacent hammers and between the cylinders of one hammer does not exceed the soil lumps size, maximally allowable by agronomic requirements, and the width of the cylinders is more than said distance or equal to it. The hammers are mounted with the possibility of changing the distance between them and the inner surface of the hollow cylinder and fixing in the required position.

EFFECT: invention improves the quality of the soil compacting and soil lumps crumbing.
