摘要：
The utility model relates to agricultural engineering, in particular to seeders for sowing grain crops. The 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 an axle, side and intermediate discs and cultivators. The cultivators are rigidly fixed around the periphery of the side and intermediate discs and form an angle, the top of which is located on the axis of symmetry of the roller attachment and is directed towards the direction of movement of the combined sowing unit. 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.Комбинированный посевной агрегат включает раму с прицепным устройством, бункер с высевающими аппаратами, опорные колеса, сошники. Каждый сошник включает стойку, стрельчатую лапу, семяпровод. По продольной оси симметрии стрельчатой лапы в передней ее части перед стойкой установлен нож, передняя грань которого заострена. Стойка выполнена пустотелой и установлена по продольной ос
