FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to precision sowing machines.

The purpose of the invention is to reduce the trauma of the seeds and increase the uniformity of seeding.

FIG. 1 is a diagram of the seeding apparatus; FIG. 2 is a section A-A in FIG. 1.

The sowing device includes a housing 1, in which a sowing disk 3 is mounted on a horizontal shaft 2, on the cylindrical surface of which cells 4 are made for seeds. In the upper part of the apparatus there is a roller-reflector 5 extra seeds with an axis placed in the grooves b, made in housing 1 with a radius equal to the sum of the radii of the seed 3 and the roller-reflector 5. The apparatus contains a seed chamber 7, a cover 8 and a passive cleaner 9, installed in the upper part of the apparatus. Roller-off, Fazhatel 5 is installed with the ability to move around the axis of the disk. The gap between the surfaces of the roller reflector 5 and the passive chip 9 is equal to

-1-2 mm (when installing a metallic metal roller). Passive chip 9 is mounted for rotational movement relative to the disk axis. The drive of the sowing disk 3 is produced from the shaft 10, on which there is a key 11, a roller-reflector 5 and a gear ring for driving the gear 12. The gear 12 is located on the shaft 13 on the bronze bushing 14. The shaft 13 with gear 12 is mounted with the possibility of radial movement similar to the shaft 10 and the roller reflector 5. The groove for moving the shaft 13 with the gear 12 is necessary to ensure the gear engagement of the shaft 10 with the gear 12 and the stalk 1 of the gear with 15. The gear 12 is necessary to drive the seed disc 3,

Plates 16 and 17 are provided for the tightness of the seed chamber 7. Plates 16 and 17 have round holes for shafts 10 and 13. When moving shafts 10 and 13, plates 16 and 17 overlap the slots. As a result, the seed chamber is sealed. To ensure the tightness of the seed chamber 7, the plate 16 is attached with a nut 18 on the shaft 10, and the plate 17 with a nut 19 on the shaft 13. The sowing disk is on the hub 20, and the hub 20 on the horizontal shaft 2 .. The seed disc 3 and gear 14 are fixed to the hub 20 with screws 21. To attach the passive tongue 9, there is a slot in the housing of the apparatus for the bolt 22, which secures the passive brush 9.

Sowing machine operates as follows.

The seeds from the seed chamber 7 fall into the cells 4 of the sowing disk 3. The excess seeds are removed by the reflecting roller 5. Then the seeds, held in the cell 4 by the wall of the housing 1 of the sowing apparatus, are lowered and dropped to the bottom of the furrow.

If it is necessary to plant seeds of other sizes (fractions), it is necessary to adjust the sowing apparatus. When setting up the metering unit, the shaft 10 is installed with the roller-reflector 5 in the calculated position. For this purpose, the nut 18 is loosened and the shaft 10 with the roller-reflector 5 is moved to the design angle; Then the nut 19 is unscrewed and the shaft 13 is moved to engage the gear 12 with the gear ring of the shaft 10 and the gear 12 to drive the hub 20 on which the lining disk 3 is mounted. Install the passive brush 9 with the gap between the cylindrical surfaces of the reflector roller and the passive Cleaner 9.

The passive cable 9 is fastened in the housing 1 of the apparatus with a bolt 22. At the end of the adjustment, tighten the nuts 18 and 19.
