Abstract

The invention discloses a containing gangue filling and tamping mechanism for a gangue filling hydraulic support. The mechanism comprises a swing beam, a floating telescopic beam, a telescopic jack, a telescopic beam and a bucket, wherein the bucket is arranged at the rear end of the telescopic beam; two ends of the telescopic jack are hinged between the front end of the swing beam and the rear end of the telescopic beam; the floating telescopic beam is a box with a front opening and a rear opening; a sliding pair is formed along the length direction between the swing beam and the floating telescopic beam; and a sliding pair is formed along the length direction between the swing beam and the telescopic beam. The gangue filling and tamping mechanism is designed to have a box containing structure, a jack is independently arranged in each branch of the swing beam and the telescopic beam, an enough space is provided to leak gangue to prevent coal ash, gangue and other impurities from leaking into the damping mechanism, the magnification ratio is increased, a filling range and the damping capacity are improved as much as possible, the gangue is fully damped and filled, and the sunk phenomenon after damping in the prior art is avoided.

Description

technical field [0001] The invention relates to a hydraulic support for a comprehensive mechanized coal mining face, in particular to an inclusive gangue filling and compacting mechanism for the gangue filling hydraulic support. 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 gangu...
