Abstract

The invention discloses a bunker dredging system with an arch breaking cap using a resonance method, which comprises an automatic reversing device, an excitation power device and a main vibrator device. The power output end of the automatic reversing device is in hydraulic or pneumatic transmission connection with the power input end of the excitation power device through a pipeline (11); the power output end of the excitation power device is in transmission connection with the reversing valve plug (9) of the automatic reversing device; and the power output end of the excitation power device is in hydraulic transmission connection with the main vibrator device through a pipeline (22). The system has the advantages of reasonable design, simple structure, pure mechanical operation, safety and reliability, labor saving, capability of solving the dredging problem after arch formation, and capability of creating excellent production benefit and social benefit for mine enterprises.

Description

technical field [0001] The invention relates to a dredging device for a coal bunker, in particular to a dredging system for a coal bunker with the resonance method of an arch breaking cap. Background technique [0002] The main failure of the coal bunker during use is the blockage in the bunker, which often leads to stoppage of production. Common blockages are jamming and arching. Jamming is the result of mechanical jamming between blocks, while arching is mainly due to the impact load during unloading and the self-weight of the storage material compacting the storage materials in the warehouse, which is more serious than the jamming phenomenon. Stablize. [0003] As people's understanding of the law of coal flow in the silo continues to deepen, through reasonable functional design of the silo, such as choosing a reasonable silo structure, improving the structure of the bucket and leak, and setting broken arches at the lower part of the silo Coal bunker blockage accidents...
