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

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the field of agricultural machine building. Soil roller is made of hollow smooth tube (1). On the periphery of the pipe surface in the longitudinal direction rectangular holes (2) are made at equal intervals. Holes (2) are made along whole length of hollow smooth tube (1). In holes (2) on the inner side of hollow tube (1) helical screws (3) are installed parallel to the axis of its rotation. Spiral screws (3) rest on hollow cylinder (4) installed coaxially inside hollow tube (1) with rectangular holes (5) made along its entire length in longitudinal direction through equal intervals. Width of holes in hollow smooth tube (1) and in hollow cylinder (4) is less than diameter of helical screws (3). Pitch of turns of spiral screw (3) is less than or equal to agrotechnical given maximum size of soil lumps. Disks (7) are installed at ends of hollow tube (1). Protrusions (8) are made on periphery of discs between spiral screws. Height of ledges (8) is equal to height of a part of spiral screws (3) projecting from hollow tube (1). Ends of hollow cylinder (4) are in contact with inner surface of discs (7).

EFFECT: higher quality of soil rolling.
