ROLLER-RIDGE FORMER Russian patent published in 2017 - IPC A01B29/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The roller-ridge former comprises a built-up frame, spherical discs, a rod with a spring. The spherical discs are mounted with their convex side to the longitudinal axis of symmetry of the roller with the ability to change the angle of attack of the spherical discs symmetrically with respect to the longitudinal axis of symmetry of the roller at an equal angle, the aperture of which is directed towards the roller movement, and fixing in the predetermined position. Between the spherical discs on the axis the flat discs are mounted at equal intervals. The outer contour of the flat discs is made multi-faceted and bilaterally sharpened. On the convex side of each spherical disc the rippers are fixedly mounted. The rippers have a shape of an elongated rectangle in cross-section and are directed towards the spherical disc rotation with their smaller side. The rippers are mounted on the spherical discs circumferentially. On the periphery of each spherical disc the shaped notches are made in the form of a semicircle and are sharpened.

EFFECT: improvement of quality of soil ridge formation is provided.
