Description

This invention relates to silos for bulk material,. for example, fodder, and can be used in feed distributors to dispense feed when raising poultry and farm animals.

Known dispenser-dispenser powdery material containing a hopper, in which a dual-flow divider, mechanical paddle or aeration rippers are installed, and a cellular rotor-dispenser is installed in its lower part.

The disadvantages of this dispenser are the high metal consumption of the structure and the dependence of the dispensing process on each element of the device. In addition, the used rippers do not exclude arching and sticking of the feed in the bunker, as they affect only part of the feed located in the lower part of the bunker. The feed enters the metering unit in an uneven flow.

Closest to the present invention is a device for dispensing bulk materials, comprising a hopper with a dispensing chamber having a perforated bottom, an electromagnetic coil, and ferromagnetic bodies used

for tapping the elastic walls of the chamber and knocking off the adhered material 2 J.

: A disadvantage of the known device is the reduction on the walls of the dispenser, which is the accuracy of the dispensing.

The purpose of the invention is the elimination of material hanging and an increase in metering accuracy.

This goal is achieved by the fact that in the device for the dispensed dispensing of bulk material containing

15 a hopper with an elastic wall and a vibratory flow booster, the elastic wall of the hopper is made with the possibility of horizontal movement relative to the hopper, and in the lower

20 parts of the elastic wall on the outer side have a drum with a drive and blades of various lengths, at the ends of which rollers are mounted, and in the upper part of the elastic wall are rigidly

25, a weight is fixed, with the drum with blades and rollers mounted for rotation with respect to the elastic wall and tension from the outer side of the elastic wall relative to the bunker. On the drawing, the proposed device. The device contains a bunker 1, at the bottom of which there is a feed line 2 with a working body 3, a push-in box 4 including an elastic wall 5 on which a weight 6 is fixed, a drum 7 with 8 long and 9 short blades with rollers 10 fixed , and the box also contains the adjusting screws 11, the Device operates as follows. The feed enters the hopper 1 containing the insert box 4 with the elastic wall 5 receiving oscillatory movements from the drum 7 containing the long-sided blades 8 and 9 and located outside the feed flow zone. Dosing is carried out by changing the distance i.e. by the side wall of the hopper 1 and the lower part of the elastic wall 5 of the insertion box 4 with the help of adjusting screws 11. The proposed device improves the accuracy of dosing due to the uninterrupted flow of bulk material into the feed line, which is ensured by the presence of a paddle drum 7, intended to vibrational movement of the elastic wall 5, and not only in its lower part, but throughout its entire area because of the presence in its upper part of the load 6. It is full Tew eliminates bridging and hang around the feed hopper obe th. The rollers 10 serve to reduce wear of the elastic wall and reduce friction between the drum blades and the elastic wall, which significantly reduces power consumption. Thus, the inventive device for dispensing bulk material permits the dispensing of bulk material to be dosed with high accuracy by eliminating the arching in the hopper. The invention The device for dispensing the bulk material, containing a hopper with an elastic wall and a vibration booster flow, characterized in that, in order to avoid sticking of the material and improve the metering accuracy, the elastic wall of the hopper is made with the possibility of horizontal movement relative to the hopper, and at the bottom of the elastic external walls are fitted with a drum with a drive and blades of various lengths, on the ends of which rollers are mounted, and in the upper part of the elastic walls and rigidly fixed load, the drum with blades and rollers rotatably mounted with respect to the elastic wall and the tension on the outer side of elastic wall relative to the hopper.
