摘要：
The utility model relates to agricultural machinery, 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, vas deferens. On the longitudinal axis of symmetry of the lancet paw, a knife is installed in front of the rack in front of the rack, 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 openings of the vas deferens and the subsoiler are located at a distance equal to the required difference in the depth of seed and fertilizer placement. An ice rink is installed behind the coulters. L-shaped brackets with guide bushings, rods with springs, U-shaped frame are rigidly fixed to the back of the frame. The packer roller is mounted in a U-shaped frame. The packer roller contains an axis, side disks, outer and inner drums made of rods. The outer drum is formed by rods arranged with equal angular pitch along the periphery of the outer surface of the side discs. The inner drum is formed by rods rigidly fixed to the inner sides of the side discs, and the rods of the outer and inner drums are parallel to the geometrical axis of rotation of the press roller.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 с
