摘要：
The utility model relates to agricultural machinery, in particular to seeders for sowing grain crops.Combined sowing unit includes a frame with a towing device, a hopper with sowing devices, support wheels, coulters. Each opener includes a stand, lancet paw, seed tube. On the longitudinal axis of symmetry of the lancet paw in its front part in front of the rack is a knife, the front edge of which is pointed. The stand is hollow and mounted along the longitudinal axis of symmetry of the lancet paw. On the continuation of the vertical axis of symmetry of the rack and coaxially to the rack, a subsoiler in the form of a tetrahedron is installed and the sharp edge is directed towards the direction of movement of the opener. An outlet is made in the lower part of the subsoiler and is directed to the side opposite to the direction of movement of the coulter, and the outlet holes of the vas deferens and the subsoiler are located at a distance equal to the required difference in the depth of seeding of fertilizers. Behind the coulters, a roller attachment is installed containing sequentially mounted rollers, an H-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. The rippers are mounted so that they form a helix. The direction of the helical line of the front roller is directed from the left side disc towards the right side disc. The direction of the helical line of the rear roller is directed from the right side disc to the side of the left side disc. The rippers in the cross section are diamond-shaped and with sharp edges are directed in different directions from the geometric axes of rotation of the rollers.Such a design of the combined sowing unit will improve the quality of sowing of grain crops.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к сеялкам для посева зерновых культур.Комбиниров
