FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building. Seeder comprises a bed, a sealed tank with a mixer and a cover, into which there is a pipe open on both sides, one end of which is submerged into the working fluid and the other end is communicated with the atmosphere, a distributor and a drive. Pneumatic mixer is used to mix the working fluid with the seeds. To adjust the pipe height and maintain tightness, an elastic coupling is provided. Supply of working fluid from the distributor and sowing of seeds is carried out directly through hydraulic seed tubes fixed on the bar with a seed sowing pitch equal to the distance between rows for growing seedlings, which are equipped with replaceable tips with holes of different diameter. Formation of furrows for sealing of seeds to a depth is carried out with working fluid at its outflow under pressure as a hydraulic ploughshare.
EFFECT: simplified design, increased uniformity of seeds embedding into soil, reduced damage of seeds.
