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

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry. The tillage roller comprises a hollow cylinder with ribs evenly spaced around the circumference. The ribs are installed along a helical line and connect vertical disks. Inside the hollow cylinder, a smooth cylinder is mounted. Its diameter is less than the radius of the hollow cylinder. The cylinders axes are arranged parallel to each other. The smooth cylinder surface is in contact with the inner surface of the hollow cylinder ribs. The smooth cylinder is installed with gaps between its base and the vertical disks, and with the possibility of free rotation around its axis and the hollow cylinder axis. The ribs are configured round-shaped. The smooth cylinder is provided with semi-circular protrusions arranged along the entire length of the smooth cylinder along a helical line. The directions of the helical lines of the ribs and those of the smooth cylinder protrusions coincide. The protrusions of the smooth cylinder and the hollow cylinder ribs are fitted with the same pitch relative to the cylinders' generatrix. The smooth cylinder protrusions are located between the hollow cylinder ribs.

EFFECT: invention provides the improved quality of compacting the soil and breaking the soil lumps.
