摘要：
The utility model relates to agricultural engineering, in particular to combined coulters for different depth application of loose mineral fertilizers with simultaneous two-line sowing of small seeded crops, and can be used in sowing machines.The technical result consists in the operational reliability of the combined opener for sowing small-seeded crops, which ensures high-quality sowing and high productivity of cultivated crops.The combined opener for small seeded crops includes a stand 1 with a furrow former fixed on it, made in the form of a flat disk 2 mounted in the vertically longitudinal plane of the opener with a sharpening angle of 30 °, the duct 3 and two installed on the left and left symmetrically with respect to the vertical longitudinal plane of the opener 4 and 5 with groove formers 6 and 7, rigidly fixed in the lower part of each vas deferens 4 and 5, made in the form of two vertically located at an angle to each other and rigidly with interconnected plates forming a wedge whose opening angle is 30 ° and a rolling roller 8 having a cylindrical shape with flanges 14 and 15 in the form of a spherical belt at the edges, the diameter D 1 of the middle supporting cylindrical part of the roller being 4 cm less than the maximum diameter D 2 of each ball zone, and the length of the supporting part is 1/3 of the length of the roller, and mounted on a rack with the ability to control its pressure on the soil. The base of the duct 3 is located below the base of each vas deferens 4 and 5, the duct 3 and both vas deferens 4 and 5 are cylindrical in the upper part, the lower part of them being conjugated to the upper at an angle of 135 °. The piping 3 and both vas deferens 4 and 5 are mounted on the rack 1 with the possibility of moving in a vertical plane with their subsequent fixation, and the piping 3 is installed on one side of the rack 1, its lower part is directed towards the flat disk 2 in the direction of its maximum deepening. The lower part of each vas
