A two-stage telescopic tamping mechanism used for a recrement filling hydraulic support comprises a balance arm body and further comprises a primary telescopic girder, primary tamping lifting jacks, a secondary telescopic girder and secondary tamping lifting jacks; the primary telescopic girder is arranged at a crotch of the secondary telescopic girder; the balance arm body is arranged at a crotch of the primary telescopic girder; two ends of the primary tamping lifting jacks are hinged between the balance arm body and the primary telescopic girder respectively; and two ends of the secondary tamping lifting jacks are hinged between the primary telescopic girder and the secondary telescopic girder respectively. According to the two-stage telescopic tamping mechanism for the recrement filling hydraulic support, a recrement filling and tamping mechanism is designed into the two-stage telescopic mechanism, and each stage of the telescopic girder is driven by two lifting jacks, so that filling scope and tamping ability are enlarged furthest, tamping and filling are fully performed, and the previous phenomenon that depression occurs after tamping can be avoided furthest; and a cover plate component is designed on each stage for sealing, so that coal ash and recrement are prevented from inleakage.
Description
technical field [0001] The invention relates to a hydraulic support of a comprehensive mechanized coal mining face, in particular to a double-stage telescopic compacting mechanism for gangue filling hydraulic supports. Background technique [0002] With the shortage of energy, the pace of coal mining in my country is accelerating day by day, and more and more mines are facing the problem of resource depletion. In order to solve the problem of "three downs" coal pressure. my country has adopted various technical measures such as traditional strip mining, relocation of villages, and filling mining to liberate the "three-down" coal pressing and increase the coal recovery rate. However, with the increase of mining depth, the increase of village relocation costs and the improvement of filling technology, filling mining technology has become a trend of vigorous development. At present, paste filling and gangue filling are generally used for backfilling gobs. The gangue needs to ...
