SOIL-CULTIVATING ROLLER Russian patent published in 2023 - IPC A01B29/04 A01B29/06 

FIELD: agriculture.

SUBSTANCE: soil-cultivating roller is a hollow cylinder equipped with an axle (1) with ribs (2) evenly spaced around the circumference and mounted along a helical line, connecting vertical discs (3). At both ends of the axle (1), L-shaped fasteners (4) are movably installed, consisting of two rigidly interconnected plates, one of which is interconnected by an additional axle (5) adapted for rotation, at the ends of which pulleys (6) are installed. On the other plates, an auxiliary axle (7) configured for rotation is mounted, at one end of which a pulley (6) is installed, and at the other end a sprocket (8) is installed. The pulleys (6) of each attachment are interconnected by belts (9), and the teeth of the sprockets (8) engage with the ribs (2). Auxiliary disks (10) are installed on the additional axis (5), the distance between them is equal to the maximum size of a soil clod, specified by agrotechnical requirements. The diameter of the auxiliary disks (10) is less than the radius of the hollow cylinder. The diameter of the pulleys (6) mounted on the secondary axle (7) is at least two times larger than the diameter of the pulleys (6) mounted on the secondary axle (5).

EFFECT: improved quality of soil rolling and braking of soil clods.
