Universal seeder pneumatic SUPN-8, SUPN-8-01, SUPN-8M

The SUPN-8, SUPN-8-01, SUPN-8 seeder is intended for dotted sowing of calibrated and uncalibrated sorted seeds of corn, sunflower, castor and sorghum, as well as seeds of fodder beans, soybeans, beans and lupine with simultaneous, separated from seeds, introduction of mineral fertilizers and rolling of the soil in rows. The SUPN-8 seeder - the vacuum is created by a fan driven by a hydraulic motor from the tractor's hydraulic system. The SUPN-8-01 seeder - the creation of a stable vacuum in the pneumatic system is provided by the SUPA 02.000 device - a gas jet compressor. The SUPN-8M seeder - the vacuum is created by a fan driven by the tractor PTO - 540 rpm. SUPN-8 planters are aggregated with YuMZ, MTZ-80/82, T-70S tractors. The principle of operation of the SUPN-8 seeder 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 SUPN-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 disk 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 SUPN-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 on the bottom of the furrow formed by the seed heel of the coulter. The spring augers of the fat-seeding device of the SUPN-8 seeder with the left and first winding take out fertilizers from the hopper into the funnels. Dispersers, performing oscillatory movements at the exit 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. The wrappers of the SUPN-8 planters cover the furrows with the seeds and fertilizers placed in them with soil. Then those who are behind the wrappers are rollingwheels compact the soil above the furrows, creating seed contact with the soil and conditions for pulling up for

them moisture. At the end, the plumes or chain even out the topography of the field and create a mulched soil layer.

Planters are aggregated with MTZ-80 tractors.

SUPN-8 SEEDER DEVICE

The SUPN-8 seeder consists of the following units: Working section – 8 pcs. Fat spreading device - 4 pcs. Fan Frame Support-drivewheels Markers Hinged device Drive mechanism Device of the working section: Bunker Seeding apparatus Combined coulter Wrappers Rolling wheel Loop Parallelogram frame Seeding device of the device: Disc with holes Dumping fork Auger Gasket with a sickle-shaped cutout Body Cover of the body with a fitting PRINCIPLE OF WORK Seeds from the hopper enter the seeding device by gravity, approach the holes, on the back side there is a sickle-shaped hole gasket cutout. The harrow prevents the seeds from clumping together and improves the access of the seeds to the holes. The vacuum from thepump is brought to the notch. 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, the rolling wheel compacts the soil in the seed zone, and the plume levels the field surface. ADJUSTMENTS Seed sowing rate — by the speed of the seeding disk — by changing the gear ratio in the gearbox — 45 gears. The depth of sowing seeds by repositioning the coulter connecting the coulter with the parallelogram frame — repositioning the coulter by one hole changes the depth by 1 cm. The width of the rows — by stopping the working sections along the frame — from the center to the edges. The width of inter-row joints — by changing the distance of the markers. The rate of fat seeding is by changing the size of the discharge window on the fat seeding device.
