Description

Technical Field

[0001] The utility model belongs to the technical field of coal preparation equipment, and particularly relates to a vibration-type coal preparation feeding and blocking prevention device. Background Art

[0002] Vibrating coal preparation equipment uses a hopper to feed materials. The hopper is a square cone with a large upper opening and a small lower opening. The coal enters the hopper and falls by its own weight. The more the coal flows downward, the smaller the cross-sectional area of ​​the hopper becomes, which creates an extrusion pressure on the flowing coal, thereby increasing the friction inside the coal. As the taper angle increases and the flow rate of the coal increases, the increase in the friction inside the coal caused by this extrusion pressure will be aggravated, resulting in hopper blockage.

[0003] In the prior art, the Chinese utility model patent document with authorization announcement number CN219850094U discloses a feed anti-blocking structure. By setting a coal preparation machine body, a feed hopper, a connecting shell, a driving part and an anti-blocking scraper rod, the coal outlet at the bottom end of the feed hopper can be swept back and forth, thereby effectively avoiding coal blockage; however, it needs to occupy the internal space of the hopper, which will block the falling of the coal and cause the coal to fall poorly.

[0004] Therefore, it is necessary to design a vibrating coal preparation feeding and anti-blocking device that does not occupy the internal space of the hopper and ensures smooth falling of the coal to solve the current technical problems. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the utility model provides a vibrating coal separation material discharging and blocking prevention device which does not occupy the internal space of the hopper and ensures that the coal falls smoothly.
