Description
Universal pneumatic seeders SPU are intended for accurate sowing of calibrated seeds of corn, sunflower, castor, sorghum, soybeans, as well as seeds of fodder beans, beans, lupins with simultaneous, separate introduction of granular mineral fertilizers and rolling of soil in rows.
The inter-sectional arrangement of the supporting and driving wheels allows you to maintain the necessary depth of seeding more precisely.
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 to the final density, excluding the use of manual labor when forming the required interval between plants. посев на конечную густоту, исключая применения ручного труда при формировании требуемого интервала между растениями.
Pneumatic seeding devices of precision sowing seeders reduce the process of crushing seeds by 10 times compared to mechanical ones.
The seed drills are equipped with a durable hydraulic marker with a larger disk, 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 it along general purpose roads without the use of additional means of transport.
The seeder is equipped with a centrifugal fan driven by the PTO of the tractor (540 rpm).
There is a flap on the fan to regulate the discharge of the air flow.
The fan is equipped with an overrunning clutch that protects the belt transmission from increased wear.
The beam of the seeder frame acts as a receiver, which ensures the same discharge in all seeding devices and eliminates the pulsation of the air flow.
The SPU-6M (8M) sowing section is equipped with discs for sowing corn and sunflower seeds. The parallelogram of the section provides better copying of the relief of the field. 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 on fields clogged with plant residues.
The amount of seeds that falls from the hopper into the seeding chamber is regulated by the shutter.(//tractor-service.com)
The presence of a viewing window allows visual control of the quality of the seeding device during the adjustment process.
An unloading hatch is provided for quick removal of seeds from 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.
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. Gas exchange is carried out thanks to open zones.
