摘要：
The utility model relates to the field of agricultural engineering. The combined tillage unit contains a frame with longitudinal and transverse beams on which racks with convex-concave discs with recesses mounted for rotation are fixed in pairs in rows along the entire working width. Disks are installed with the ability to control the angle of attack and deepening. The discs are staggered on the frame. The recesses are made in the form of a semicircle and are located on the periphery of the disk with equal angular pitch. Behind the disks of a convex-concave shape, a roller prefix is installed, containing sequentially mounted rollers, an H-shaped frame, brackets and rods. A nut and spring are installed on each rod. Each roller contains an axis, side and intermediate disks mounted on the axis at equal intervals in the horizontal plane, rippers. On the periphery of the side and intermediate discs, triangular recesses are made. The rippers are mounted in triangular recesses of the side and intermediate discs so that they form a helical line. The direction of the helical line of the front roller starts from its longitudinal axis of symmetry and is directed towards the side discs. The direction of the helical line of the rear roller starts from the side discs and is directed to the longitudinal axis of symmetry of the roller. The rippers in the cross section are square and twisted along the entire length by an angle a relative to their longitudinal axis of symmetry so 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 axes of rotation of the rollers installed in series. EFFECT: improved quality of surface tillage. 4 ill.Полезная модель относится к области сельскохозяйственного машиностроения. Комбинированный почвообрабатывающий агрегат содержит раму с продольными и поперечными брусьями, на которых по всей ширине захвата парными рядами закреплены стойки с дисками выпукло-вогнуто
