摘要：
The utility model relates to agricultural engineering, in particular, to seeders for ridge sowing of row crops.The ridge seeder includes ridge formers mounted on the frame, sowing machines, packer rollers. Openers are installed in front of the formers. 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 in the direction opposite to the direction of movement of the coulter. Ridge formers contain a rack, lancet paw, blade and bracket. The blade is made spherical and mounted on the inside of the wing of the lancet paw at an acute angle to the direction of movement with the ability to control this angle and move the blade in height relative to the cutting edges of the wings of the lancet paw and fix it in the desired position. The concave surface of the blade is directed in the direction of movement of the comb, and the dumps of each pair of comb formers are installed symmetrically with respect to the line of sown seeds. The packer rollers contain a frame, spherical discs, a packer drum with pointed rippers, an axle, rods with springs and are located behind the crest formers.Such a design of the ridge seeder will improve the quality of sowing of row crops and the formation of ridges of soil over sown seeds.Полезная модель относится к сельскохозяйственному машиностроению, в частности, к сеялкам для гребневого посева пропашных культур.Гребневая сеялка включает закрепленные на раме гребнеобразователи, высевающие аппараты, прикатывающие катки.
