摘要：
The utility model relates to agricultural machine building, namely to the working bodies of seeding machines, and is intended for uniform and separate in depth planting of mineral fertilizers and seeds of agricultural crops, mainly small-seeded, for example, flax, rape and grasses. The technical result is to improve the quality of sowing small-seeded crops based on the development of a simple in design and reliable in operation opener and justification of its optimal design parameters that meet the agrotechnical requirements for the cultivation of small-seeded crops； the yield of agricultural crops increases: vegetables, grasses, flax, rape, meeting the needs of the food, textile, pharmaceutical industry, fodder production, etc. The combined opener for small-seeded crops contains a ski-shaped runner 1 mounted on its day surface in a longitudinal-vertical plane along the axis symmetry of the rack 2, which is a multi-point support with a base length of at least 1/4 of the length of the support surface of the runner 1. To the right and left of the stand 2 in the longitudinal-vertical plane along the axis of symmetry of the runner 1 with the ability to move in the vertical plane with subsequent fixation, a furrow former is installed - seed guide 7 and bed former-seed guide 8. Furrow-former-seed guide 7 and bed former-seed guide 8 have a tubular section along their entire length, are released through the runner below its support surface. The base of the furrow-guide 7 is located below the base of the seed-guide 8. The furrow-guide 7 in its lower part is equipped with a furrow 9 rigidly fixed on it, made in the form of two vertically arranged at an angle to each other and rigidly interconnected plates, forming a wedge, the opening angle of which is 25 °, and the bed former-seed guide is bent in the lower part at a right angle, made with an oblique cut of the outlet. The minimum distance S from the center of the furrow former-guide in the longitudinal-vertical plane of the
