Description

The invention relates to the storage and distribution of bulk materials and can be used in the chemical, agricultural and other sectors of the national economy.

A device for collapse of hard-to-flow material in a hopper is known, comprising a vertical hollow shaft, an annular groove located in it and rods fixed to the rod end with a working member, which is a cone-shaped screw, facing up, with the screw made detachable along its longitudinal axis, and each part is pivotally connected to the shaft. A disadvantage of the known device is its complexity, unreliability of collapse in bunkers of rectangular cross section, as well as the ability to zrushat particulate material, for example seeds. .. The purpose of the invention is to increase reliability in operation. ; ,. -

The goal is achieved in that in a bunker device comprising a housing and a mechanism for collapse. including a conical divider mounted with the possibility of reciprocating movement and consisting of two articulated vertical parts and a drive for their relative movement, the mechanism for collapse is equipped with a frame fixed to the bottom with brushes on the bottom end, the parts of the divider are spring-loaded one to the other , in one of the parts there is an elastic gasket, and in the other a cavity is formed, while the drive for moving the parts of the divider is made pneumatic and puppy with a cavity dissector.

In FIG. 1 shows the proposed device, a General view; Fig. 2 shows a vibration mechanism for collapse.

The device comprises a hopper body 1 and a collapse mechanism in the form of a pneumatic vibrator including a conical divider suspended on a flexible link 2 in the hopper with the possibility of translational movement and consisting of half 3, to which half 5 is attached via a hinge 4 and is spring-loaded spring b to the elastic gasket 7, which protrusion 8 is fixed in the recess 9 of half 3, and half 5 is provided

a working chamber 10, which is connected by a channel 11 and a flexible hose 12 to a source of the working medium (not shown in Fig.) under pressure (compressed air or steam during freezing of the product).

If necessary, the mechanism for collapse is equipped with additional elements that increase the area of interaction of the mechanism with the material being processed, for example, antennas 13 mounted on the halves 3 and 5 of the conical dissector in the region of the maximum vibration amplitude of the halves, as well as a frame 14 made along the cross section

the housing 1 of the hopper, and suspended on flexible rods 15 to a conical divider. To interact with the walls of the hopper, the frame is provided with rollers 16 or brushes 17. The hopper device operates as follows. In the initial position, the collapse mechanism is located at the bottom of the hopper. In case of unreliable expiration of the material discharged from the hopper, a compressed hose is fed through the hose 12

air (or steam) into the cavity of the working chamber 10, where with a set of pressure there is a force overcoming the spring 6, the halves 3 and 5 are rotated relative to the hinge 4 to form a gap between the edge

the working chamber 10. and the elastic gasket 7, after which the compressed air from the working chamber 10 is vented to the atmosphere and, under the action of the spring b, the halves 3 and 5 together with the antennas 13 are returned to the position

close to the original. Next, the vibration cycle is repeated. Using a lifting device (not shown in FIG.) And flexible hm 2, the mechanism is slowly raised, under the influence of the vibration of antennas 13, halves 3 and 5,

as well as flexible sleeves 15, the material contained in the hopper is loosened and poured down. The pulsed effect of the exhaust compressed air on the material being processed is favorable for further destruction. The proposed device is simple to manufacture and maintain, its use in the national economy will increase the performance of hopper devices by increasing the reliability of collapse with protection from destruction of granular material.
