ROLLER-RIDGE FORMER Russian patent published in 2013 - IPC A01B29/00 A01B35/16 A01B35/28 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, in particular, to tillage rollers. The roller-ridge former comprises a frame, an axle (11) and concave discs (10), freely installed on semi-axes (8) with the possibility of their movement in the vertical plane and fixing in the giving position. The roller frame is made composite with the ability to change the setting angle of the side beams (1) together with the concave discs (10) to the direction of motion. Between the concave discs (10) on the axle (11) provided with shoulders (12), the flat discs (13) are located at equal distance from the longitudinal axis of symmetry of the roller with the ability of their movement along the axle of the roller. On the edges of the flat disks (13) on the axes (16) with the same angular pitch the planks (17) of equal length are mounted. The ends of the planks (17) mounted opposite each other are connected by hinges. The planks (17) are located at an acute angle to the axis of the roller. The shoulders (12) are located on the outer side of the flat disks (13), and between the shoulders (12) and the flat disks (13) the flexible elements (18) are mounted.

EFFECT: constructive solution enables to improve the quality of forming the soil ridge due to creation of an optimal structure of the soil and the desired profile shape of the ridge.
