[0002] During the longwall mining process, when encountering large faults, it is necessary to separate and transport gangue to improve coal quality, which requires the use of a gangue scraping device. The gangue scraping device generally includes a support frame, a lifting mechanism, and a scraping mechanism. The support frame has two sets of V-shaped support mechanisms to support the conveyor belt and form grooves. When gangue on the conveyor belt is about to pass the device, the lifting mechanism lifts the belt to a flat surface, and the scraper blades, which are intersected with the conveyor belt, move down to contact the belt. The gangue that subsequently passes is guided by the scraper blades to one side of the device and falls into the face opening for loading and transportation.
