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

FIELD: agricultural engineering.

SUBSTANCE: tillage roller is made of a smooth hollow tube (1). Along the periphery of the smooth surface of the pipe in the longitudinal direction at equal intervals, rectangular holes (2) are made. The holes are made along the entire length of the hollow tube (1). Spiral screws (3) are installed in the holes (2) on the inner side of the hollow pipe parallel to the axis of its rotation. The spiral screws (3) are supported by round rods (4) installed symmetrically about the axis of rotation of a hollow smooth pipe and parallel to it. The width of the holes (2) in the hollow smooth pipe (1) is less than the diameter of the spiral screws (3). The pitch of the turns of the spiral screws (3) and the distance between adjacent rods (4) are less than or equal to the agrotechnically specified maximum size of soil lumps. Disks (6) are installed at the ends of the hollow smooth pipe (1), in which holes are made at an equal distance from the centers of the disks.

EFFECT: improvement of the soil compaction quality.
