    The invention relates to agriculture, in particular to sowing aggregates for precision sowing seeds. The purpose of the invention is to simplify the design and reduce the width between the rows. The assembly comprises a housing 2 with a low pressure chamber 1. A support disk 7 is fixed on the shaft 4 on the shaft 4, on which the sowing disk 8 with suction holes 9 is placed, which is connected to the disk 7 by the type of a bayonet bolt. For this purpose, holes 8 in the disk 8 are made, the width of which decreases in the course of its rotation. The radial edge of the disk 8 rests on the felt sealing ring 10. The disk 8 is closed by a seed receiving chamber 25, which is made in a cup shape, which is connected to the seed hopper and has a partition wall 26 and brackets for fastening it to the housing. The chamber is adjacent to the edge of the low pressure chamber. The disk has mounting bolts 16 and mixing bolts 34 that interact with the agitator 31. When the disk 8 rotates, the seeds are sucked to the holes 9 and transferred to the discharge zone, where they are separated from the disk when the vacuum is cut off. When switching to sowing seeds of other sizes, the chamber 25 is uncoupled, the disk 8 is disconnected from the support disk and replaced with a new one. 10 hp f-ly, 5 ill.

    The invention relates to agriculture, in particular to sowing aggregates for precision sowing seeds. The purpose of the invention is to simplify the design and reduce the width between the rows.
    Fig. 1 shows the closing part of the sowing unit, side view; Fig. 2 shows the housing of the low pressure chamber of the sowing unit, side view j in Fig. 3, section A-A in Fig. 2 in Fig. A shows the housing of the low pressure chamber with the disc mounted with holes and removable closing part, side view ; figure 5 - the inner side of the closing part.
    The sowing unit has a cup-shaped body 2 forming a low-pressure chamber 1 with a hub 3, in which sleeve 5 is mounted on shaft 4, Case 2 can be connected to the exact seeding frame using bracket 6 by means of bracket 6. The drive shaft 4 is rotated by a drive element (not shown). A support disk 7 is mounted on the sleeve 5, which is rigidly fixed on the shaft 4. A sowing disk 8 is connected to the supporting disk 7 as a bayonet bolt, in which a suction hole 9 is made at a dividing circumference at certain intervals, the diameter of these holes is smaller than the diameter of the sown grains. With its radial outer edge, the disk 8 abuts on the felt sealing ring 10, which is mixed with graphite. The outer diameter of the disk 8 is less than the internal diameter of the cylindrical outer wall 11 of the housing 2,
    In the unloaded condition, the disk 8 is a slightly truncated cone, thereby creating a tension in the assembled state on the outer edge of the disk towards the sealing ring 10. The disk 8 has longitudinal holes 12 (Fig. 4) The direction of rotation of the disk with holes indicated by arrow 13. The longitudinal holes 12 on the bottom, when viewed in the direction of rotation, have a portion 14 of greater width, to which an portion 15 of smaller width adjoins.
    The support disk 7 has fixing bolts 16 parallel to the axis. Each fixing bolt 16 has no

    mediocrely over the supporting disk 7, the landing slot (not shown), which basically corresponds to the wall thickness of the disk 8. Thus, to fix the disk 8 on the basic disk 7, it is only necessary to fit it onto the basic disk 7 so that the fastening bolts 16 pass through the sections 14 longitudinal holes 12. Then it is necessary to turn the disk 8 against the direction of rotation of the unit relative to the supporting disk 7 (Fig. 4).
    A hole 17 is provided in the rear wall of the housing 2 for a connecting element 18 of the exhaust system, and a connecting pipe 19 is also provided which is pressed against the disk 8 by means of a spring 20. A connecting element 21 for supplying compressed air is located adjacent to the connecting pipe 19 to the pipeline 22 of compressed air and is intended for purging in order to clean the holes 9 of the disk after the sowing grains fall out (Fig. 2).
    Between the outer radial edge of the support disk 7 and the sealing ring 10, the disk 8 overlaps the annular zone in the direction of rotation of the disk 8 by means of a gasket 23. By means of V-shaped brackets 24, the cup-shaped chamber for receiving seeds is detachably connected to the body 2 of the low pressure chamber. The outer edge of the chamber 25 is adjacent to the outer wall 11 of the housing 2.
    A separation wall 26 is formed in the chamber 25, which, when assembled, terminates directly in front of the disk 8. An inlet 27 for seed is provided on the cylindrical portion of the chamber.
    The separation wall 26 (Fig. 5) starts at the lower end of the inlet 27. At the beginning of the separation wall 26, a seed tank 28 is installed, closed by a shutter 29, which allows the sowing unit to be completely free of seed.
    In the separation wall 26, a rubber-like piece of material 30 is used, which has an elastic stirrer 31 in the form of a rod. The end 32 of the agitator is located below the dividing wall 26, and the other end 33 is above the dividing wall 26
    in the area of the inlet port 27. The piece of material 30 allows the stirrer 31 to tilt in all directions.
    When the chamber 25 is put on, the end 32 of the agitator 31 is in the zone of movement of the fastening bolts 16 and the mixing bolts 34 located on the disk 8. The bolts 16 and 34 (Fig. 3) have a curved working surface. Between the two mounting bolts 16 are mixing bops 34, the working surfaces of the mounting and mixing bolts of different sizes protrude into the chamber 25. Thus, the interaction of the stirrer 31 with the bolts 16 and 34 contributes both to the deflection of the stirrer in the plane (FIG. 3) and movement of the ends of the agitator at a right angle to this plane.
    Brackets 24 (figure 2) mounted on the housing 2 can be rotated around the rotary axle 35.
    A viewing window 36 is provided in the wall of the chamber 25, through which the filling of the holes with 9 seeds can be monitored. In addition, an eccentric 37 is mounted in the wall of the chamber 25, on the outer end of which (FIG. 1) an actuating member 38 is located, which cooperates with a scale 39. Inside the chamber 25, an elastic metal band 40 adjoins to the eccentric 37 (FIG. 5), which using the fastening element 41 is fixedly connected with the cylindrical section of the chamber 25. The metal tape 40 is made in the form of a cutting element. Its position from the pitch circle, along which the holes 9 of the disk 8 are located, can be changed by adjusting the actuating element 38 accordingly.
    The cylindrical wall section of the chamber 25 is cut in the lower zone (Fig. 5) and forms a scraper 42. Thus, a free space is formed for sowing grain from the holes 9 of the disk 8.
    The opening 43 at the base of the chamber 25 allows air to flow from the connecting element 21 for supplying compressed air.
    The housing 2 of the chamber 1 of low pressure, as well as the chamber 25, are made as deep-drawing parts of a foil material.
    The device works as follows.

    Seeds from the hopper 28 enter the upper part of the chamber 25 to the separation wall 26, and are stirred by the stirrer 31 when interacting
    5 end 32 with bolts 16 and 34. The other end 33 of the agitator moves in the area of the inlet port 27 and thereby prevents the seeds from hanging.
    When the disk 8 rotates, the holes 9 suck up the seeds, which are fixed in them by a vacuum supplied from the low pressure chamber 1, and transferred to the discharge zone, where the holes overlap from the vacuum and under the influence of gravity and the scraper 42 they separate from the disk and fall into the opener (not specified). In doing so, the openings 9 are flushed to prevent them from clogging.
    When switching to sowing seeds of other sizes, the camera 25 is easily removed by unlocking the clips 24, the disk 8 is disconnected from the supporting disk 7 and replaced by another.
