| description | The pebble coal scraper device of the medium-speed coal mill comprises a scraper, a connecting arm, a fixing seat and a rotating shaft, the scraper is connected to the rotating shaft through the connecting arm, and the two ends of the rotating shaft are connected to the fixing seat in a rotating mode. The utility model belongs to the technical field of power generation and combined heat and power production, and aims to solve the problem that a pebble coal scraper is easy to be stuck to cause fracture in the prior art. The scraper has the technical effects that by arranging the rotating shaft, when the scraper is jammed by materials in the using process, the scraper can rotate around the rotating shaft, so that the bottom of the scraper is lifted to a certain height, the scraper bypasses a jamming point, breakage caused by jamming of the scraper is effectively prevented, the equipment maintenance workload can be reduced, the safety risk in unit operation is reduced, and the service life of the scraper is prol |
