摘要：
The utility model relates to the field of agricultural engineering, namely to devices for the simultaneous planting of seeds of various crops in the soil at different depths and with a variable row spacing, and can be used when sowing forage crops that differ in morphological and biological characteristics. The technical result is to create a simple by design and reliable operation of the seed drill opener, carrying out simultaneous strip sowing of different levels of depth, taking into account the morphological and biological characteristics of the sown seeds and fulfilling the specified agrotechnical requirements, which is expressed in increasing the yield of forage crops and improving the quality of feed. In addition, the technical result is to reduce the labor intensity of the sowing process by reducing the cost of pre-sowing soil cultivation, which will certainly affect the cost of the resulting crop and agrotechnical terms. parts with a flat-cutting paw 2 and placed on a rack 1 with the ability to move in a vertical plane a freely rotating flat disk 3. The rack 1 is made hollow, in the cavity of which on both sides of its longitudinal-vertical plane symmetrically with the possibility of movement in a vertical plane with their subsequent fixation installed identical plates 8 and 9, each of which is made in the form of a club, the shank 10 and 11 of which is mated with the upper part of the plate at an angle of 90 °, is made with a cutting edge along the movement of the opener with a sharpening angle of 15 ° and is located under the flat-cutting paw 2. Between the plates 8 and 9 and the side walls of the rack 1, there are seed tubes 14 and 15, each of which is a flexible transparent hose, the lower end of which is bent in the direction opposite to the direction of movement of the opener, and is located under the flat-cutting paw 2 behind the shank 10 and 11 plates. The outlet openings of the seed pipes 14 and 15 are located and fixed in a plane parallel to the t
