Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, devices for loading seed hoppers.

There are known devices for loading bunkers of seed units, made in the form of a tank for loading material, to which a cone distributor is attached and with a hole 1 connected to the loading nozzles.

Such devices have the disadvantage that, after IB, after filling the hoppers of the metering units, the entire excess of feed material is transported to the common container through one of the loading nozzles, which can lead to a blockage of the pipeline leading to the distributor.

In order to avoid clogging of the distributor with the loaded material, the distributor is equipped with a grill installed in front of the cone from the air supply side, and connected to the tank from the feed side of the charged material. The dimensions of the lattice holes are smaller than the particle sizes of the material to be loaded.

The drawing schematically shows the proposed device, side view.

A closed common container 1 has a hatch 2 in the upper part for loading seeds. A cone 3 is located in the lower central part. An annular window 4 is made between the cone and the base of the hopper of the sowing apparatus. The window communicates the cavity of the bunker with the cavity of the distributor 5. Distributor pipes Q are symmetrically connected to the upper part of the distributor. uploaded material. A pressure pipe 8 is connected to the distributor, through which air flows from the fan 9. The hoppers of the sowing units 10 are closed with lattice covers 11, the bore sizes of which are also smaller than those of part 1 C

uploaded material.

The device works as follows. From the closed container 1, the material under the force of gravity flows through the annular window to the peripheral part of the lattice tureboro 7. The air flow is supplied by the fan 9 through the discharge pipe 8 to the lower part of the distributor 5, passes through the lattice partition and moves the material through the distribution pipes G

G, the hoppers of the sowing apparatus 10, of which the air escapes through the lattice covers 11 into the atmosphere.

The hoppers of the metering units are filled with up to those, until the level of the loaded material in them reaches the ends of the pacnpe; io-plentiful pipes and does not block their outlet openings. In this case, the air outlet to the atmosphere is stopped and the material does not move out of the distributor.

After filling the% nkerov, the fan can be turned off. Their subsequent filling is carried out by putting the fan into operation. The device can work continuously, FILLING-UP bunker of the sowing devices.

Claims (2)

I. Device for loading seed hoppers with seeds, including a tank equipped with a flow distributor of loaded seeds, having a cone and openings with loading nozzles attached to them, a fan for supplying air to the distributor, THAT, to prevent the seed distributor from clogging, it is provided with a grid installed in front of the cone from the side air supply, and attached to the tank from the side of the supply of seed to it. 2. A device according to claim 1, characterized in that the dimensions of the holes of the lattice are smaller than the sizes of particles of seeds.
