摘要：
The utility model relates to agricultural engineering, in particular to seeders for subsoil-spread sowing of grain crops. The combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels and coulters. The coulters contain a hollow rack-vas deferens, a spherical disk and a divider. The concave side of the spherical disk faces the field surface. The divider is installed under the hollow rack-vas deferens in the internal cavity of the spherical disk. Behind the coulters, a roller attachment is installed containing sequentially mounted rollers, an H-shaped frame, brackets and rods. A nut and a 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. combined sowing unit will improve the quality of sowing crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности к сеялкам для подпочвенно-разбросного посева зерновых культур.Комбинированный посевной агрегат включает раму с прицепным устройством, бункер с высевающими аппаратами, опорные колеса и сошники. Сошники содержат полую стойку
