TILLAGE ROLLER Russian patent published in 2021 - IPC A01B29/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The tillage roller consists of an H-shaped frame, brackets, rods and rollers of a loosening and leveling type. Each rod has a nut and a spring. The ripper roller contains a axle, side discs, a hollow cylinder mounted on side discs. There are clod crushers in the form of a four-sided pyramid on the periphery of the hollow cylinder. The crushers are rigidly fixed with the base to the outer surface of the hollow cylinder in parallel circular rows along its entire length in such a way that one of the sharp edges of each crusher is directed towards the movement of the tillage roller, and the edges and tops of the crushers are directed in different directions from the geometric axis of rotation of the tillage roller. The leveling roller contains an axle, side and intermediate discs, mounted on the axle at regular intervals in the horizontal plane. Triangular recesses are made on the periphery of the lateral and intermediate discs. The rippers are installed in the triangular recesses. The rippers form a helical line. The direction of the helical line starts from the longitudinal axis of symmetry of the leveling roller and is directed towards the side discs. The rippers are square in cross-section and are twisted along the entire length by an angle α relative to their longitudinal axis of symmetry in such a way that the sharp edges of each ripper form helical lines, and the sharp edges of the rippers are directed in different directions from the geometric axis of rotation of the leveling roller.

EFFECT: invention improves tillage quality.
