Description

one

The invention relates to seeding machines.

Seeding annarates are known, including a bunker, the bottom of which is made with an outflow window for seeds, and a cellular sowing disc with reflectors and ejectors located above the bottom. In these devices, the sowing disc rotates and the bottom of the hopper is stationary.

The seeding rate hem n is regulated by changing the speed of rotation of the sowing disc. However, with an increase in the speed of rotation of the sowing disc, the filling of the cells, and consequently, the uniformity of sowing in the known apparatus, is sharply disturbed.

With an increase in the uniformity of sowing of seeds when operating at higher speeds in the proposed apparatus, the sowing disk is fixed and equipped with a valve device located above it, made in the form of combined reflectors and ejectors, hinged on the rotary disk relative to the sowing disk, and the bottom of the bunker performed rotating.

FIG. 1 shows the proposed seeding apparatus, front view, section; in fig. 2 is a section along A-A in FIG. one; pas figs. 3 is a section along BB in FIG. I.

The apparatus contains a hopper 1, rotating

the bottom 2 of which is fixed on the shaft 3, the cellular sowing disk 4 and the valve device 5 mounted above the bottom. The bottom 2 of the apparatus is grasped with this wire 6 made in the shape of a funnel.

The valve devices are located above each hole in the bottom of the hopper and include reflectors 7 and 8 seed ejectors pressed against the seed disc.

a spring 9 and hinges fixed to a lead rotating relative to the sowing disc.

The cells of the sowing disc are evenly spaced around. Bottom hole

the hoppers and the valve devices located above them are on a circle of the same radius as the cells of the sowing disc, but are made with an angular displacement relative to the latter so that in one

The turn of the bottom 2 through each of its holes sow the seeds from all the cells of the sowing disk one by one or in groups.

The device works as follows. The seeds in the hopper fill the cells of the stationary seed disc. The rotation of clan devices, including the valve and ejector, ensures that seeds are mixed over the cells, better filled and eliminated arching. When the shaft rotates 3 seeds,

those that do not enter the cells are cleaned with seed reflectors, and those located in the cells are fed by ejectors through the aligned holes of the bottom 2 into this wire.

Subject invention

A sowing device, including a bunker, the bottom of which is made with a discharge window for seeds, and a cell sowing disc with reflectors located above the bottom

and pushers, characterized in that, in order to increase the uniformity of sowing of seeds when working at higher speeds, the sowing disk is fixed and equipped with a KlainainM device located above it, made in the form of combined reflectors and pushers hinged on the rotating disk relative to the sowing disk leads, and the bottom of the hopper is rotatably mounted.
