The invention relates to agricultural machinery, in particular to sowing devices seeders adesemowo sowing.Known metering apparatus A. with. N 375046, consisting of banks with a bottom horizontal row of the disk and a reflector in the form of a cylindrical brush with the axis of rotation perpendicular to the axis of rotation of the disk, enclosed outside area of cover.The disadvantage of this metering device is that seeding the uh seed of the smallest size.Also known metering apparatus A. with. N 654204 containing auger, mounted on a shaft that is rigidly connected to a cylindrical casing, provided with a driven through holes, a hopper and a cylindrical screen.The disadvantage of this seed is the lack of a push operation to push the seeds out of the cells and their subsequent treatment, which can lead to clogging of the latter.As a prototype of the selected pneumatic metering device.with. N 1271397 A1 containing the drum through cells and internal wavy surface with increased roughness. In the area of seed release pneumatic nozzle attached to them brush reflectors.The disadvantage of this seed is the presence of passive brush reflector, does not exclude sticky two small seeds in one in one mesh, in addition, the speed of movement of seeds by pnevmoservice largely depends on their aerodynamic properties, which affects the uniformity of the distribution of seeds in the row.The purpose of the invention is the improvement of piece selection of seeds and increase the uniformity of their distribution in bores the MS active brush reflector excess seeds, working in collaboration with the squeezing roller. Brush the reflector also functions as an ejector. In the area of discharge of the seeds has a guide tray and transporting the brush is driven from the wheels.1. The claimed technical solution - "Metering system" - meets the criterion of "Novelty of technical solutions. Patent information search to identify analogs and prototypes were carried out on funds of CGSH, STIC, CHAUM and Republican library, Kazan. As a result it was identified technical solution - Pneumatic sowing machine" (and.with. N 1271397 A1, MKI A 01 C 7/04, 1984), taken as the closest analogue (prototype).2. The claimed invention meets the criterion of "industrial technical solution". On the date of filing of application prototypes and put into production in the Karelian isthmus "spark" Sabinsky district of the Republic of Tatarstan.3. Comparative analysis of the proposed technical solution is not only known in the field of technical solutions - analogues, but the prototype allowed us to identify a number of distinctive characteristics, forming a new body, unknown of "prior art", con is - metering apparatus equipped with a squeezing roller with the surface of flexible resilient material;
- squeezing roller is driven from the metering drum;
- metering unit includes a guide tray and transporting the brush;
- transporting the brush is driven by the wheels.Having at least five significant from the prototype characteristics, the proposed solution fully complies with the receipt of a new "technical result".In Fig. 1 schematically shows a metering unit, side view; Fig. 2 - also, front view.Metering system consists of a hopper 1 (Fig. 1), the metering drum 2 through 3 cells. On the outside of the mesh is blocked by the casing 4, fixed to the end plates of the drum 5. In the cover is located inlet opening 6. It also fixed hub shaft 7 of the drive brush reflector 8 with the drive mechanism 9. In the area of the touch of the brush reflector to the inner surface of the metering drum from the outside has the squeezing roller 10. To the drum adjacent the transporting brush 11, a closed casing 12, and the guide chute 13. Through leads 14, 15 guest sprockets and chain 16 made the drive transporting brush from the packer 17. Sowing barai brush reflector 8 and transporting brushes 11 are of the scraper 19 and 20.The apparatus operates as follows. From the hopper 1 seeds through the loading opening 6 enters into the internal cavity of the metering drum 2. During rotation of the drum seeds sink into the mesh 3. Loss of seeds from the mesh prevents the casing 4. At least the rotation of the metering drum, the seed falls into the range of "A" of the squeezing roller 10, which is due to its elastic surface is embedded in the mesh 3 with the outer side of the drum and within cells shifts the seeds in the zone of action of the brush reflector 8, facilitating sweep "extra" seeds without damaging them and without being in mesh doubles seeds of even the smallest of fractions. As further rotation of the drum seeds in zone "B" are pushed under the action of the brush pile reflector 8 and the centrifugal force to the outside of the drum and engaged by the pile transporting brushes 11, then slide on the guide tray 12, and then is discharged into the open furrow at the point of maximum proximity to the ground with a velocity equal to the velocity of movement of the planter and oppositely directed. This contributes to the actuator (14, 15, 16) transporting brush from the packer 17. In zone "C" pile transporting brush 11 is embedded in the emptied mesh 3 and contributes to their impact in the tray 13. Brush the reflector 8 and transporting the brush 11 is cleaned from dust and seeds stuck in the pile by the scraper 19 and 20. 1. Metering unit containing casing, a metering drum-through cell and set it active brush reflector seeds, characterized in that the reflector performs the function of the ejector seeds, also seeding apparatus equipped with passive squeezing roller with the surface of flexible resilient material adjacent the outer side to the metering drum in the impact zone of the brush reflector, and a brush for transporting seeds from the guide tray.2. Sowing apparatus according to p. 1, characterized in that the drive of the transporting brushes made from packer units.
