[CN 201821087887.2] Hydraulic Mechanical Device for Dredging Large Coal Block at Entrance of Transfer Machine
[CN 201821087887.2] Title of hydraulic mechanical device for dredging large lump coal blockage at the entrance of the reloader: Application number of hydraulic mechanical device for dredging large lump coal blockage at the entrance of the reloader: CN 201821087887.2 Applicant: China Coal Zhangjiakou Coal Mine Machinery Co., Ltd. Application Date: 2018-7-2 Patent Type: Utility Model The utility model relates to the technical field of fully mechanized working face reloader, specifically discloses a hydraulic mechanical device for dredging large lump coal blockage at the entrance of reloader. The device is detachably arranged on the transfer machine to move and rotate the large lump of coal blocked at the inlet of the transfer machine so that it can be introduced into the transfer machine. The device is composed of telescopic baffle, telescopic block, hydraulic system, etc. The telescopic baffle and the telescopic block are respectively arranged at the right side plate of the middle groove of the inlet of the transfer machine and the left side plate of the transition groove. Under the action of the hydraulic system, the telescopic baffle reciprocates parallel to the coal flow direction of the transfer machine, and the telescopic block reciprocates vertically to the coal flow direction of the transfer machine. The telescopic baffle and the telescopic block act together to push and rotate the blocked large lump of coal into the transfer machine to dredge the congested coal flow. The utility model has simple principle, compact structure, simple operation, reduces the workload of traditional manual maintenance, eliminates potential safety hazards, reduces non-mechanical failure downtime, and improves the safety performance and working efficiency of the transfer machine.
