SEEDER-CULTIVATOR SECTION Russian patent published in 2021 - IPC A01C7/00 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering; it can be used to prepare a field for sowing, for subsurface continuous, strip and row sowing of cereals, legumes, small-seeded, rowed and industrial crops and grass mixtures, including stubble and untreated agricultural background, with simultaneous application of dry fertilizers to the soil, as well as for row-to-row treatment of rowed crops. A seeder-cultivator section contains a parallelogram suspension for a beam, on which a working body for grinding plant residues with a function of a copying wheel, a coulter, a coverer, a rolling tool are installed sequentially. The function of the copying wheel of the section is performed by a shredder roller, made in the form of a hollow cylinder, the surface of which is formed by ribs with removable knives fixed on them, protruding above the roller surface. Protruding flat disc knives are attached to sidewalls of the roller. The coulter has in its lower part a spherical disk mounted in a bearing assembly, to the inner concave surface of which a removable conical diffuser is attached. Behind the coulter, a coverer and a rolling tool are installed.

EFFECT: use of the invention will expand its functionality and increase functional reliability.
