FIELD: agriculture; machine building.SUBSTANCE: invention relates to agricultural machine building, particularly, to tools for formation of soil comb. Roller-comber comprises composite frame, freely installed on axles (6), seals (9) with sealer-ripper unit (14) placed between them with possibility of free rotation on axis (13). Frame is made with possibility of changing of side beams (1) installation angle together with seals (9) to direction of movement and fixation in preset position. Sealer-ripper unit (14) is made in form of cylinder, on the outer surface of which radial pointed pins (15) are located, and it is installed with possibilities to change its position together with axis (13) in horizontal plane and lock in required position. Seals (9) are formed by spiral, which shape represents the surface of ball segment. Seals (9) are installed with convex side inside the roller. Outer spiral turn forms a circle.EFFECT: such design solution is aimed at improvement of quality of soil comb formation.1 cl, 2 dwg |
