Abstract

The invention relates to the storage and unloading of bulk materials using bunkers and can be applied in the mining, chemical, construction, food and other sectors of the national economy. The aim of the invention is to increase the intensification of the crushing process. The bunker contains the housing 1 and the bottom 2. On the frame 3 there is an actuator 4. On each working body 5 several clamps 6 are rigidly fixed, to which are attached blunt rods in the form of pins 7, steel ropes 8 circumferentially and segments 9 along the chords . The bunker works as follows. In the process of unloading the material includes a drive 4. Oscillatory movements of the drive 4 transfers the working bodies 5. As a result of the interaction of the pins 7, the ropes 8 and 9 with the bulk material, its loosening and collapse of the vault occurs. 1 hp f-ly, 5 ill.

Description

The invention relates to the storage and unloading of bulk materials using bunkers and can be applied in the mining, chemical, construction, food and other sectors of the national economy.

The aim of the invention is to increase the intensification of the crushing process.

FIG. 1 schematically shows a hopper for bulk materials; in fig. 2 - the same, top view; in fig. 3 a section A A in FIG. 2; in fig. 4 - section B B in FIG. 3; in fig. 5 shows a section B according to FIG. 3

The hopper for bulk materials comprises a housing with vertical walls 1 and a bottom 2. On the frame 3 in the upper part of the housing there is an oscillatory movement drive 4, which is connected with a material flow inducer. The material outflow booster is made in the form of several vertically installed working circumferentially close to the walls 1 of the housing and made in the form of steel wire ropes of the working members 5. On each working opiane 5 several clamps 6 are rigidly fixed, to which blenders are fixed with fair-haired horizontal pins 7, endless steel ropes 8, located around the circumference and segments of steel ropes 9, located along the chords. The inner surfaces of the clamps 6 are made along a screw line. The working bodies 5 are permanently spring-loaded with tensioning springs 10 and secured by studs 11 on the oscillating movement drive 4 and the bottom of the horn, i of the bunker. The oscillating drive 4 in the vergical plane of motion is made in the form of an electromagnetic vibration mechanism, in which the core 12 of the electromagnet is rigidly fixed at the center of the work

whose platform 13 of the electromagnet and the frame 3, and the bore 14 by means of compression springs 15 is connected to the working platform 13 and working members 5. The compression stiffness of the springs 15 is greater than the rigidity of the extension springs 10.

The hopper for bulk materials works as follows.

In the process of unloading the material and breaking its arches, the electromagnetic vibration mechanism 4 located on the frame 3 is applied. The alternating electric current passing through the coil winding worn on the core 12 creates an electromagnetic field causing periodic attraction of the core 14 and core 12 and repulsion under the action of springs 15 compression. Oscillatory movements of the vibration mechanism are transmitted through the studs 11, the clamps 6 are spring-loaded with the help of springs 10 to the working bodies 5, except for the working platform 13. As a result of the interaction of horizontal pins 7, endless steel cables 8 and pieces of steel cables 9 with loose material, it is loosened and crash in case of hangup. The working bodies 5 affect the bulk material throughout the cross section of the hopper.

The supply of additional working bodies located horizontally around the circumference, and chords connected by clamps with vertical working bodies, which are made in. in the form of steel wire ropes, spring loaded in

the lower part is fixed on the drive of oscillatory motion and the bottom of the housing, and performing a drive oscillating in a vertical plane of motion in the form of an electromagnetic vibration mechanism will allow stabilizing the material unloading by expanding the zone of material collapse in the bunker.
