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 axle (1) with ribs (2) evenly spaced around the circumference connecting vertical discs (3). Axis (1) of the hollow cylinder is connected to hitch (4) and mounted for rotation separately from vertical discs (3) through transmission mechanism (5) mounted on hitch (4). Auxiliary discs (6) are rigidly mounted on axis (1) of the hollow cylinder. The radius of auxiliary discs (6) is less than the distance from the centre line of the hollow cylinder to the inner surface of ribs (2) by half the diameter of the soil clod established by the agrotechnical requirements. On the sides along the periphery of auxiliary discs (6), rods (7) are installed axially and at an equal distance from each other, the length of which and the distance between adjacent rods (7) are equal to the agrotechnically specified maximum size of the soil clod. Rods (7) installed on adjacent auxiliary discs (6) are displaced relative to each other by a distance equal to half the maximum size of a soil clod specified by agrotechnical requirements. The distance between adjacent auxiliary discs (6) is equal to two agrotechnically specified maximum sizes of a soil clod.

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