Description

Technical Field

[0001] This utility model relates to the technical field of coal mine coal bunker cleaning equipment, and in particular to a coal mine coal bunker cleaning mechanical device. Background Technology

[0002] In the coal mining process, coal storage and transfer bunkers are usually set up on the surface and underground. Because coal has a relatively high viscosity, it is easy to stick to the bunker walls, forming blockages. Over time, it is also easy to clump together, which can block the coal bunker in severe cases, causing the coal bunker to be blocked and unable to flow, leading to production stoppage and affecting the safe production of coal mines.

[0003] Currently, methods for resolving coal bunker blockage, caking, and coal spillage typically involve manual removal with steel shovels or water jetting, which are labor-intensive and prone to causing water accumulation at the bottom of the bunker. Even worse, some methods use explosives for blasting, which carries a high risk. Therefore, there is an urgent need to design a mechanical device for cleaning coal bunkers to solve these technical problems. Utility Model Content
