Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ash removal devices, in particular to an automatic ash removal device for a belt coal conveying corridor of an open coal mine. BACKGROUND

[0002] Currently, the coal transfer of an open coal mine is mostly completed by a rubber belt conveyor. When the rubber belt conveyor is arranged, a corridor needs to be built to avoid the coal being transferred under the open state from being affected by rain or other factors. However, the corridor arranged with the rubber belt conveyor has the problem that the accumulated ash or fallen coal is difficult to clean during the production process, and the material scattered during the transportation of the rubber belt conveyor and the material brought back by the rubber belt surface of the rubber belt return will also fall on the ground of the corridor. The above reasons cause a large amount of dust and scattered material in the corridor to be treated.

[0003] The ash removal device for a belt corridor disclosed in Publication No. CN210674604U uses a negative pressure mechanism to adsorb and clean the fallen material and dust. However, some of the scattered material on the ground of the corridor has relatively large particles, about 1-10 cm, and some is fine dust and accumulated ash. The fine dust and accumulated ash can be cleaned by the negative pressure dust collection equipment, but the larger particles need to be collected by manual cleaning with a shovel or other tools for reuse. Moreover, the scattered material after cleaning cannot be automatically re-transported after recovery, and manual re-transportation is required, which is time-consuming and labor-intensive. Therefore, we propose an automatic ash removal device for a belt coal conveying corridor of an open coal mine. SUMMARY
