Description

Technical Field

[0001] The utility model relates to the technical field of bucket wheel machines, in particular to a belt cleaning device for bucket wheel machines. Background Art

[0002] The bucket wheel belt has serious material carryover. It has become normal for small holes and torn buckles to appear on the bucket wheel belt. It often needs to be shut down for repair and patching, which increases the cost of patching. In addition, it takes a long time to replace the belt after too many torn holes, which reduces the throughput of the cantilever belt, seriously affects the production rhythm, and increases the cost of equipment maintenance. The loss of the wet bucket wheel sweeper will also increase when transporting lump ore and some relatively wet and sticky materials. Through long-term observation of the bucket wheel stacking and reclaiming situation, we found that although the effect of relying on the sweeper alone is good, once a lump of ore falls to the non-working surface, it will cause the first and second level sweepers to directly make holes in the belt or even tear it, resulting in large losses. After some materials dry on the return belt, the sweeper will scrape them hard, which will also reduce the life of the sweeper. Summary of the invention
