摘要：
The utility model relates to the field of agricultural engineering. The combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters and a roller. The coulters contain a stand, to the base of which a lancet paw is fixed, and a seven-duct. The seed pipe is made in the form of a hollow pipe and at the bottom is equipped with a U-shaped bracket, the ends of which are directed in the direction opposite to the direction of movement of the coulter. The seven-conduit is installed with the possibility of vertical movement along the rack, and in cross-section the seven-conduit has the shape of a circle. Behind the coulters, a roller attachment 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 α 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. Improving the quality of sowing crops. 5 ill.Полезная модель относится к области сельскохозяйственного машиностроения.
