The invention relates to agricultural machinery, in particular, to these wires of sowing machines, and can be used in sprouts for single-grain precision sowing of tilled crops, in particular, the turn of sugar beet.

The purpose of the invention is to ensure the uniformity of the intervals between the seeds at the outlet of the wire, by ensuring a constant size of the flow area along the length of the wire.

Fig. 1 shows a telescopic sem wire, viewed from the side; Fig. 2 is section A-A in Fig. 11 in Fig. 3 is section B-B in Fig. 2; 4 shows the installation of a telescopic sem wire in a grid.

The telescopic sem wire contains inlet 1 and outlet 2 cylindrical nozzles having equal passage openings for seeds. At the junction, the inlet 1 is provided with rods 3, and the outlet 2 is equipped with rods 4. The rods 3 and 4 are mounted around the circumference and form a passage hole for seeds equal to the through hole of the nozzles 1 and 2. At the junction there are rods 3 of the nozzle 1 alternate with rods 4 nozzles. Moreover, at the junction, the ends of the rods 3 are fastened with the rim 5, and the ends of the rods 4 with the rim 6, i.e. the articulation point is formed by that section of the rods 3 and 4, which is closed between rims 5 and 6,

The gap oi (Fig. 2) between the rods 3 or 4j forming the nozzles 1 or 2, respectively, is chosen smaller than the diameter of the rods of the nozzles inscribed in between the rods and is made smaller than the wire inscribed in this wire,

4, Sem wire according to claim 1, characterized in that it is provided with an elastic corrugated casing with perforation attached to the end portions of the stem nozzles.

The feed opening of the wire of the circumference wire (Fig. 2, the circumference of the diameter d), the number of rods, as well as their cross-sectional shape can be varied - round, triangular, etc.

At the junction, the ends of the rods 3 and 4 of each nozzle have a section 7, made along the brachistochrone (FIG. 3),

reversed convexity to the sem axis of the wire. The cutting plane 7 intersects with the end of the rod 4 at its center along a straight line (Fig. 2), the perpendicular plane in which the axis of the seven wires and the axis of the rod 4 are located. This prevents the seeds from colliding with the end of the rods, as the seeds can be uneven. they enter the gap between the rods before

the middle.

When sowing seeds of seed crops, the seed wire can be used in the seedlings (Fig. 4) consisting of a common seed bunker 8, on which, under the sowing devices 9 installed on the bunker 8, the inlet pipes 1 of the telescopic sem wires are vertically fixed. Seed hopper 8 mounted on frame

with support wheels 10. The outlet nozzle 2 of this wire is fixed on the coulter 11. The junction point of the nipples 1 and 2 is covered by an elastic corrugated casing T2, for example

rubber, with perforation.

The telescopic sem wire operates on the seed as follows.

When the seed is moving on the wheels 10, the seeds are selected individually, from the single seed bunker, the seeds are sowed by the sowing device 9 and selected in the inlet 1, where

unimpededly overcome the junction of nozzles 1 and 2 and get into the outlet nozzle 2, which directs the seeds into the groove formed by the opener 11. The latter forms a groove for the seeds, copies the soil microrelief, making oscillatory movements in the vertical plane relative to the seed bunker 8 Together with the coulter 11, they move with the rods 4 nozzles 2, which, as in directions, move between the rods 3 of the output nozzle 1. The coaxiality of the inlet 1 and the output 2 nozzles is not disturbed due to the presence of rims 5 and 6, which prevent lateral displacement of the rods 3 and 4 at the articulation point. Elastic corrugated casing 12 prevents the ingress of abrasive particles in the contact points of the rods 3 and 4.

When the rods 3 and 4 and the rims 5 and 6 are made sufficiently strong, this wire can act as a coulter suspension 11.

To the seed bunker 8, the proposed telescopic sem wire can be fastened directly with rods 3 without the aid of pipe 1, and to the vomer 11 directly with rods 4.

If pneumatic sowing devices 9 are used on the spreader, accelerating the seeds due to excessive air pressure, then it is expedient to carry out the outlet nozzle 2 of the telescopic semen wire as a device for neutralizing the energy of compressed air, which is performed on the extension of the rods 4

outlet pipe 2, I

The shape of the seed aperture formed by the rods and 4 telescopic wires,

determined by the shape of the bore of the articulated nozzles 1 and 2. If the articulated nozzles 1 and 2 have a seed aperture, made, for example, rectangular or triangular, the rods 3 and 4 are installed in such a way as to form a through hole of an appropriate shape and size.
