[0002] Coal bunkers are necessary intermediate storage devices in coal production and transportation. Raw coal is continuously input and output from the coal bunkers. Since the raw coal contains moisture and other impurities, over time, the raw coal will form a layer of adhesive on the bunker wall under high pressure. This layer of adhesive makes the surface of the coal bunker wall uneven, which not only hinders the flow of raw coal in the coal bunker, but also reduces the effective space of the coal bunker and reduces production efficiency. Therefore, it is necessary to regularly clean the coal bunker through a special bunker cleaning machine.
