Description

The utility model relates to devices for storing and subsequently dispensing difficult-flowing materials prone to caking and collapse, and can be used in various industries.

A bunker device for bulk materials is known, comprising a housing and a horizontal shaft mounted in its walls, equipped with a shredder made in the form of disks, on the surface of which there are curly tides (German Patent No. 949936, class 81 e 136, publ. 1956).

The disadvantage of the bunker device is low intensification and low productivity collapse.

The closest in technical essence and the achieved result to the proposed one is a hopper for bulk materials, comprising a housing and a collapse mechanism placed therein, including a horizontal drive shaft with obliquely mounted discs, while the shaft is equipped with protrusions symmetrically arranged relative to the axis with a spherical surface, and the disks are mounted on the protrusions pivotally by means of detachable clips (RF patent No. 2250188, class B65D 88/68, publ. 04/20/2005. Bull. No. 11, authors Burobin VN, Evstropov AS, Shilkin VI “Bunk er for bulk materials ").

However, the schematic design of the collapse mechanism determines the rotation of the blades of the collapsor with the same angular velocity and rotational movement, which is a low intensification of collapse.

This technical solution is selected by the authors as a prototype.

The technical result is to increase the intensity of collapse and increase the productivity of collapse.

The technical result is achieved by the fact that the horizontal shaft of the hopper and the horizontal shaft of the gearbox are aligned, the collapse mechanism is made of at least two paired disks, one performs rotational motion, the other oscillates, the central pairs of disks are at an acute angle to the center, and the pairs of disks are closer to the bunker wall is parallel to it, and all disks are rigidly mounted on the horizontal shaft of the bunker, and cylindrical and elliptical wheels with the possibility of rotational and vibrational motion, which in turn are fixed to the horizontal shaft coaxial gear, wherein the cylindrical gear wheel is fixed to the horizontal shaft of the hopper, and an elliptical wheel is fixed to the horizontal rotary shaft coaxial reducer.

An increase in the intensification of the destruction of arches in the hopper occurs due to the creation of a rotational-vibrational rotation process, thereby providing a multiple change in the direction of the angular velocity, the implementation of the collapse mechanism from paired disks, the central pairs of disks are located at an acute angle to the center, and the pairs of disks closer to the wall of the hopper are parallel her, as well as the implementation in the gearbox on the carrier of cylindrical and elliptical wheels and placement of coaxial shafts of the hopper and gearbox.

In FIG. 1 - General view of the hopper for bulk materials.

In FIG. 2 is a kinematic diagram of a shredder for bulk materials.

The hopper for bulk materials consists of a housing 1, coaxially located horizontal shafts 2 and 3, disks 4 and 5, a gear housing 6, a cylindrical wheel 7, a satellite 8, elliptical wheels 9 and 10, cylindrical wheels 11, 12, 13, 14, a carrier 15, drive shaft 16.

The device operates as follows.

Material loaded through the upper part of the hopper body using a conveyor (not shown) or by any other means, in the initial period, the shredder passes unhindered and is poured through the unloading window. As the layer of material loaded into the hopper increases, its compaction and arch formation occurs.

Upon termination of the flow of material from the hopper, which indicates the formation of the arch, include the drive. The torque from the high-speed shaft 16 of the gearbox, which is located in the gear housing 6, is transmitted to the cylindrical wheel 7, which rotates the satellite 8. The satellite 8 transmits rotation to the carrier 15, which drives the cylindrical wheels 11, 13 and the elliptical wheel 9, which are placed on carrier 15. The cylindrical wheel 13 rotates around a cylindrical wheel 14. The cylindrical wheel 11 is engaged with the cylindrical wheel 12, which rotates the horizontal shaft 3, and the elliptical the wheel 9 transmits vibrational rotation to another elliptical wheel 10, which in turn rotates the horizontal shaft 2. The horizontal shaft 3 of the housing of the hopper 1 rotates the disks 4, 5, and the horizontal shaft 2, located coaxially with the horizontal shaft 3, and drives the disk 5 into oscillatory motion. In the operating mode of collapse, the oscillatory movement from the gearbox is transmitted to the shaft of the collapse demolition. A pair of disks will make a rotational movement, while the disk 5 will oscillate with respect to the disk 4. Thus, when the shaft rotates, the blades of the shaft breaker are driven in a complex motion.

Cyclically repeating the process of movement of the disks is the preferred condition for the effective work of collapse, since the kinematics of the movement of the disks provides a multiple change in the direction of angular velocity, which increases the intensification of collapse and the performance of the hopper.

The proposed joint constructive solution of the hopper and gearbox provides a 1.5-2 times increase in productivity and reduces the time of collapse.
