摘要：
The utility model relates to agriculture. The combined soil cultivating unit includes a frame on which vertical racks with axles are mounted and spherical disks mounted on the axles with the possibility of rotation, having an adjustable angle of attack, subsoilers, transport and technological wheels are installed behind the unit. On the periphery of each spherical disk, recesses are made in the form of a semicircle, and the cutting edge of the spherical disks is sharpened. A roller attachment is attached to the back of the unit frame, containing sequentially mounted rollers of the loosening and leveling type, an H-shaped frame, brackets and rods. Nuts and a spring are installed on each rod. The loosening roller contains an axis and disk rippers mounted on the axis of the loosening roller at equal intervals in the horizontal plane. On the periphery of the disk rippers made triangular recesses. The vertices located between the triangular recesses are also made triangular and bilaterally sharpened and directed in different directions from the geometric axis of rotation of the disk cultivators. The leveling roller contains an axis, side and intermediate disks mounted on the axis at regular intervals in the horizontal plane. On the periphery of the side and intermediate discs, triangular recesses are made. In the triangular recesses of the side and intermediate discs, rippers are also mounted so that they form a helix. The direction of the helix of the leveling roller starts from its longitudinal axis of symmetry and is directed towards the side discs. The rippers in cross section are square and twisted along the entire length by an angle α relative to their longitudinal axis of symmetry so that the sharp edges of each ripper form helical lines. The sharp edges of the rippers are directed in different directions from the geometric axis of rotation of the leveling roller. Provides improved soil cultivation. 4 ill.Полезная модель относится к сельскому хозяйству. Комбиниров
