Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, working bodies of sprouts, for example, for sowing sugar beet.

The aim of the invention is to improve the quality of seeding by improving pre-day seed selection.

FIG. 1 shows the sowing unit, section; in fig. 2 - the same, side view; on f | ig. 3 is a view A of FIG. 2; in fig. 4 - view B in FIG. 1 (seeding disc from the peripheral rim side); in fig. 5 is a view of B in FIG. four; in fig. 6 - section G-Y in FIG. four.

The metering device includes a housing 1 with a window 2 for feeding seeds, sowing a cellular disk 3 mounted on a shaft 4. The disk 3 has a peripheral rim 5 with notches 6 and a cell 7 on the side of the filling zone.

Above the disc in the seed chamber is located 10

mounted on the shaft 4. Using a peripheral rim with cuts 6 of the seed disc 3, a group of seeds is selected from the layers of seeds and accelerated to the speed of the disc. Selected from the sem group, interacting with the seeds of the layer and with the trailing edge of the notch 12, passes into the unit cell 7. The posterior edge of the notch is flush with the wall 13 of the cell and is located to the surface of the disk 14 at an angle oi greater than the friction angle of the seed . The level of seeds in the seed chamber is below the zone of cleaning the disc of lipstick seeds. When the disk rotates, the seeds, found in 1 unit in the unit cell and in the notch of the peripheral rim, are removed from the layer. When passing under the cavity 8 in the seed chamber, the notches are cleaned from the seeds under the action of 11, the extra-rapid forces.

Sem remaining in a single cell on

cavity 8, in the housing is made ringing all the way from the cleaning zone to the zone

Target protrusion 9 with groove 10 for peripheral rim and ejector 11.

The rear edge 12 of the notch 6 coincides with the plane of the wall 13 of the cell 7 and is inclined to the surface 14 of the disk 3 at an angle ω.

The device works as follows.

Seeds coming from the hopper into the housing 1 through the seed delivery window 2 are driven by the sowing disk 3,

filling, separated from the seed chamber annular protrusion 9, the groove 10 of which includes the peripheral rim of the seed disc. In the ejection zone, the cell with the remaining seed is cleaned with a knife-like ejector 11.

The use of the invention makes it possible to provide high-quality single seed sowing of sugar beet without crushing.

Claims (2)

1. SOWING UNIT containing a hopper for seeds, a housing with a cylindrical surface, in which a metering disk with a peripheral rim and cells on its lateral surface is installed, characterized in that, in order to improve the quality of sowing by improving the single selection of seeds in the peripheral rim a disk has been cut in front of each cell, and the rear edge of each cut in the direction of rotation is located in the plane of the cell wall and is inclined to the surface of the disk at an angle greater than the seed friction against the disk, and An overlapping cell is filled from the cleaning zone to the filling zone with an annular protrusion with a groove for the peripheral rim. 2. The apparatus by π. 1, characterized in that, in order to improve the cleaning of disc cells from excess seeds, a cavity is made in the seed chamber above the disc, the depth of which is equal to the width of the rim.
