FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, devices for single-piece feeding, for example, seeds.

Limers of the device for single-stage feeding of seeds, including a housing with a channel for transporting seeds, a rotary-mounted cylinder centered on the housing with spiral spiral. In the upper part of the cylinder is a cell, cut in half by a groove in which the clip ejector falls.

In known devices, seed dropping occurs without prior orientation, directly from the mass, which reduces the likelihood of filling the cells and sharply limits the performance of the device. In addition, in known devices, the seeds in the lower compacted layer are in a rotational motion, which increases their abrasion prior to dosing and degrades its accuracy. Such devices are complicated by installing ejectors in the outflow window, which also leads to damage to the seeds.

In the proposed device, in order to increase the reliability of single-piece supply of seeds while reducing their damage, the housing is mounted on a horizontal axis rotatably and has spiral grooves on the inner surface, and the cylinder is hollow, with through slots in its lower part, fixedly and a rotating puck is placed inside it; in addition, to create a minimal layer of seeds inside a stationary cylinder and

forced circulation of seeds along the cylinder of the direction of spiraling of the auger spirals and the spiral grooves of the hull of the projectile. On fpg. 1 shows a diagram of the proposed device, front view, section along A-A

Ivid B; in fig. Figure 2 shows the dosing process.

The device includes a hopper 1, which communicates with a fixed hollow cylinder 2 through the valve 3. In the lower part of the fixed cylinder there are made through this guide slots, over which elastic element 4 is mounted. Inside the cylinder 2 there is a screw 5 on the shaft 6, and in its end wall outlets. The stationary cylinder is housed in housing 7,

which rotates on the horizontal axis and

has on the inner surface of the spiral

grooves.

The device (see Fig. 2) works as follows.

Seeds or tubers from the hopper 1 by gravity flow to the valve 3 of the stationary cylinder 2 and through the window in its lower part into the internal cavity of the cylinder. The subsequent axial movement of the seed (planting) material is ensured by the action of the rotating screw 5. Seeds or tubers, when moving, fall into the guide grooves of the stationary cylinder 2, and from there they individually sink into the spiral grooves of the housing 7. The depth of the grooves is adjusted so that the sunken seeds (tubers ) were simultaneously in contact with the spiral groove and the walls of the fixed guide slot. As a result of this interaction, the slots and grooves of the sunken seeds (tubers) move to the outburst.

The elastic element 4 mounted above the outflow opening prevents damage to the seeds (tubers) at the outlet. The feed capacity of the spiral grooves of the housing 7 is slightly higher in performance than the feed of the material with the screw 5, which eliminates the possibility of filling the fixed peel 2 beyond a certain optimal level. A single blowout of seeds (tubers) can, if necessary, occur through one or more outlets.

To adjust the performance of the device, one of the slits (or several) can be covered by an elastic element 4, which in this case is pushed into the cavity of the stationary cylinder 2.
