TILLAGE ROLLER Russian patent published in 2017 - IPC A01B29/00 

FIELD: agriculture.

SUBSTANCE: roller includes a hollow cylinder (1) and ribs (3) evenly spaced along the helix between vertical discs (2). A smooth cylinder (4) is installed inside the hollow cylinder (1). The smooth cylinder (4) is installed with the possibility of rotation about its axis and the geometric axis of the hollow cylinder (1). The outer diameter of the smooth cylinder (4) is larger than the inner radius of the hollow cylinder (1). The geometric rotation axis of the hollow cylinder (1) is parallel to the geometric rotation axis of the smooth cylinder (4). The smooth cylinder (4) is equipped with flanges. The ribs (3) are connected to each other by guides (6) installed parallel to the bases of the hollow cylinder (1), in which the flanges are mounted. The guides (6) are made U-shaped and are installed by the open side of the profile inside the hollow cylinder (1). The clearance between the surface of the smooth cylinder (4) and the inner surface of the ribs (3) of the hollow cylinder (1) is made minimal. The diameter of the ribs (3) is made smaller than or equal to the diameter of soil lumps, specified by agrotechnical requirements.

EFFECT: improving the soil compacting quality.
