SOIL-CULTIVATING ROLLER Russian patent published in 2022 - IPC A01B29/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The soil-cultivating roller is a hollow cylinder (1) equipped with an axle (2) and mounted on a frame (3) for rotation. Inside the hollow cylinder (1) there is a smooth cylinder (4), the diameter of which is less than the radius of the hollow cylinder (1). Hollow cylinder (1) and smooth cylinder (4) are perforated with identical oval holes (5 and 6). The holes (5 and 6) in the hollow and smooth cylinders (1 and 4) are staggered with their major axis parallel to the axis (2) of the tillage roller. The distance between adjacent holes (5 and 6), measured along the axis (2) of the tillage roller, is equal to the width of the holes (5 and 6). The holes (6) in the smooth cylinder (4) are displaced along the axis (2) of the tillage roller relative to the holes (5) in the hollow cylinder (1) by half the length of their larger axis.

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