Seeder universal supn-8 ot vom in stock, spare parts for SUPN, UPS, Kirovohrad region.

Seeder SPU-8 (SUPN-8) is intended for dotted sowing of calibrated and uncalibrated sorted seeds of corn, sunflower, castor and sorghum, as well as seeds of forage beans, soybeans, beans and lupine with simultaneous, separate seeds, applying mineral fertilizers and rolling the soil in rows. SPU-8 seed drills are aggregated with YuMZ, MTZ-80/82, T-70S tractors.
The principleoperation of the SPU-8 planter (SUPN-8) is as follows. By means of the transmission mechanism from the supporting and driving wheels, the rotation of the seed sowing discs and spring augers of the fat seeding apparatus is carried out. The vacuum in the horseshoe-shaped cavity of the cover of the seeding device of the SPU-8 seeder is created either by a fan driven by a hydraulic motor from the tractor's hydraulic system, or by vacuum from the tractor's exhaust using a special pipe. To control the amount of discharge on the fan or on the exhaust, a control valve with a diaphragm pressure gauge is installed.

The seeds are sucked into the holes of the rotating disc located in the discharge zone and transported from the intake chamber to the discharge zone. The removal of excess seeds that have been sucked into the holes back into the intake chamber is carried out by the pins of the fork installed in the intake chamber of the SPU-8 seeder device, between which the seeds that have been sucked into the holes pass when the disc rotates. In the lower part of the device, when the hole passes from the vacuum zone to the atmospheric pressure zone, the seeds fall one by one from the hole and are placed at the bottom of the furrow formed by the seed heel of the coulter. The spring augers of the SPU-8 (SUPN-8) seeding device with left and first winding take out fertilizers from the hopper into the funnels.(//tractor-service.com)

Dispersers, making oscillating movements at the outlet windows of the funnels, disperse the fat flow, ensuring a uniform stream in the fat ducts, and then into the furrows formed by the fat heels of the coulters. SPU-8 seed drills (SUPN-8) cover furrows with seeds and fertilizers placed in them with soil. Then those who are behind the wrappers are rollingwheels compact the soil above the furrows, creating contact between the seeds and the soil and conditions for them to absorb moisture.
