Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of buffer idler, in particular to a buffer idler group support of mining conveying belt conveyor. BACKGROUND

[0002] In the mining industry, the conveying belt conveyor is the key equipment for material transportation. Different belt conveyors have different requirements for the angle of the idler support when conveying materials due to differences in material properties, conveying distance, and environment. If the roller support angle is not reasonable, there will be a large angle of friction between the belt and the idler, which will increase the resistance and affect the production efficiency. Secondly, uneven stress is common during belt operation, and excessive local pressure can easily cause excessive belt wear. In addition, the shift of the supporting gravity center will cause vibration and shaking, reducing the stability and reliability of the entire buffer idler group support. Furthermore, the mining environment is usually dusty, and dust easily accumulates at the connection between the buffer roller and the support rod. This additional friction caused by dust during the rotation of the buffer roller accelerates the wear of the components and may cause abnormal rotation of the buffer roller, leading to belt deviation and other problems. When encountering different levels of dust accumulation, fixed cleaning intensity and speed of the dust removal equipment cannot be flexibly responded. Finally, belt deviation will cause shutdown adjustment, affecting the continuity and stability of the conveying operation and reducing production efficiency. Therefore, we propose a buffer idler group support for a mining conveying belt conveyor. SUMMARY
