UPS-8 analogue of Vesta universal furrow seeder, Nikolaev region.

UPS 8 – universal pneumatic seed drills intended for accurate sowing of calibrated seeds of corn, sunflower, castor bean, sorghum, soybean, as well as seeds of fodder beans, beans, lupine with simultaneous application of granular mineral fertilizers separately from the seeds and rolling of the soil in lines.
It is also possible to sow uncalibrated seeds, but in this case the accuracy will directly depend on the difference in size and the degree of damage of the seed material.
Precise seed drills ensure sowing at the final density, excluding the use of manual labor when forming the required interval between plants.
Pneumatic seeding devices of precision sowing seeders reduce the percentage of seed crushing by 10 times compared to mechanical ones.
All drive shafts of grain and fat seeding devices are mounted on rolling bearings.
Due to the location of the axis of the support-drive wheels on the same line as the grain coulters, synchronous copying of the field relief is achieved by both the frame and the sowing section.
A tread with grippers ontyres support-drivewheels reduce their slippage, which ensures a given interval between seeds.
The seed drills are equipped with a durable hydroficated marker with a disc of a larger diameter, which has the ability to change the angle of attack to obtain a clearly visible trace.
To order, the planters are equipped with a transport device, which allows you to move them along general purpose roads without the use of additional means of transport.
The semi-automatic coupling ensures quick and safe connection of the seeder with the tractor.
The hitch has the ability to shift along the frame beam, which allows sowing with a row spacing of 450 mm with tractors that do not change the track width (for example, T-70C).
The seeder is equipped with a centrifugal fan driven by the tractor PTO at 540 rpm.(//tractor-service.com)
For guaranteed retention of heavy seeds of leguminous crops (soy, etc.) on the holes of the seeding discs, the fan of the seeder is equipped with an additional air duct.
There is a flap on the fan to regulate the vacuum of the air flow.
The fan is equipped with an overrunning clutch that protects the belt transmission from excessive wear.
The frame of the seeder acts as a receiver, which ensures the same vacuum in all seeding devices and eliminates the pulsation of the air flow.
The sowing section is equipped with a coulter for sowing corn and sunflower seeds. As a result of the modernization, the sowing section was equipped with a 2-circuit drive of a new design. Reliable protection of the drive ensures work in fields clogged with plant residues.
The amount of seeds that falls from the hopper into the seeding chamber is regulated by a shutter.
The comb-type discarder of excess seeds ensures accurate one-grain sowing.
An unloading hatch is provided for quick removal of seeds from the chamber of the seeding device.
A harrow is installed on the seeding disk, which prevents seeds from compacting and hanging in the chamber of the seeding device.
The fat sowing system through the fat coulters provides the possibility of applying mineral fertilizers away from the row with the necessary amount of displacement, which excludes the harmful effect of fats on the seeds.
An unloading hatch is provided in the bunker to remove the remains of mineral fertilizers.
Rolling the soil in the sown rows improves the contact between the seeds and the moist soil at the bottom of the furrows, provides capillary rise of moisture and creates favorable conditions for earlier and friendly seed germination.
