TILLAGE ROLLER Russian patent published in 2023 - IPC A01B29/04 

FIELD: agricultural engineering.

SUBSTANCE: roller is made in the form of a hollow smooth cylinder (1). On the periphery of the smooth surface of the hollow cylinder at regular intervals in the transverse direction rectangular service openings are made. Below the service openings, ribs are installed radially for the entire length of the hollow smooth cylinder. In the ribs at an equal distance from each other, through holes are made radially, in which studs (3) of the same length are installed. At the outer ends of the studs (3), sealing elements (4) are installed parallel to the ribs, having the shape of segments in cross section. The length of the sealing elements is equal to the length of the ribs. Compression springs (5) are installed on the studs (3) between the sealing elements (4) and the ribs. Holes (6) of the same diameter are made in the sealing elements (4). Studs (7) are radially mounted on the ribs coaxially with holes (6) on the sealing elements (4). The inner ends of the studs (3) are equipped with self-locking nuts.

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