Seeder SUPN-8, Dnipropetrovsk region.

TECHNICAL SPECIFICATIONS SUPN-8
It is aggregated by tractors of the traction class of 0.9-1.4 tons and 2 tons (T-70S). Hinged The width of the grip is 7.2 m. 8-row. Row width up to 90 cm. Working speed up to 12 km/h. Productivity up to 5 ha/hour.
WORKING PRINCIPLE
The seeds from the hopper enter the seeding device by gravity, approach the holes, on the reverse side of the hole there is a sickle-shaped cutout of the gasket. The harrow prevents the seeds from clumping and improves the access of the seeds to the holes. The vacuum fromthe pump is brought to the cutout. As a result, the seeds are sucked into the holes. The disc rotates and brings the holes with the seeds to the dump fork. If two seeds are attached to the hole, only one seed will pass through the tines of the fork. Next, the holes with the seeds go down, the cutout in the gasket ends, the vacuum disappears and the seed falls into the coulter.
The coulter makes a furrow, first lays the fat, they are sprinkled with earth, and then, in the furrow, the seeds fall, so that there is no contact between the seeds and the fat, and the seeds do not burn. Wrappers close the furrow, which the rollingwheel compacts the soil in the seed zone, and the plume levels the surface p
