Hydraulic uncovering mechanism of crusher

The utility model relates to the technical field of crushers, and discloses a crusher hydraulic uncovering mechanism which comprises a feed port of a crusher and a frame arranged at the top end of the feed port, two ends of the frame are hinged with head end covers, the tail ends of the end covers are provided with bending plates which are inclined upwards, the tail ends of the bending plates are hinged with the moving end of a hydraulic cylinder, and the moving end of the hydraulic cylinder is hinged with the moving end of the hydraulic cylinder. The fixed end of the hydraulic cylinder is hinged to the side face of the frame. According to the hydraulic uncovering mechanism of the pulverizer, the two end covers are driven to be overturned through stretching and retracting of the hydraulic cylinder, so that the feeding port is closed, graphite is prevented from splashing, and the spray heads at the bottoms of the end covers spray air downwards, so that diffused graphite powder flows downwards, and the graphite
