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 the whole length of hollow tube (1). In holes (2) on inner side of pipe parallel to axis of its rotation there are helical screws (3). Spiral propellers rest on hollow cylinder 4 fitted coaxially inside hollow tube (1) with lengthwise rectangular-shaped openings (5) made along its length in equal length. Width of holes in hollow tube (1) and in cylinder (4) is less than diameter of spiral 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). On periphery of disks between spiral screws (3) protrusions (8) with sharpened edges are made. Height of ledges (8) is equal to height of part of helical screws (3) protruding from hollow smooth pipe (1), and length is to interval between holes (2) in hollow smooth pipe (1). Ends of hollow cylinder (4) are in contact with inner surface of discs (7).

EFFECT: higher quality of soil rolling.
