[0059] During receiving, the moving mechanism 4 drives the moving frame 43 and the receiving hopper 1 to move along the slide rail 41, and drives the receiving hopper 1 to move below the discharge opening of the smelting furnace to wait for receiving. The rotating mechanism 3 drives the cover plate 2 to rotate around the hinge point, so that the cover plate 2 is obliquely arranged at an angle with the horizontal plane. The cover plate 2 is in an open state at this moment, and the molten metal liquid flows into the receiving hopper 1 from the opening at the top of the receiving hopper 1. The obliquely arranged cover plate 2 can also appropriately block the liquid from splashing outward to harm the workers. After receiving, the rotating mechanism 3 drives the cover plate 2 to rotate in the opposite direction again, so that the cover plate 2 is buckled at the opening of the receiving hopper 1. The cover plate 2 is arranged in the horizontal direction at this moment, and the cover plate 2 is in a closed state. Then, the moving mechanism 4 drives the receiving hopper 1 to move to the next processing station. The cover plate 2 provided in the application improves the safety of the device, avoids the molten metal liquid in the receiving hopper from splashing to the outside during movement, and the clamping and limiting assembly 44 can clamp the slide rail 41, thereby reducing the risk of the receiving hopper 1 being overturned by the impact of the molten metal liquid during receiving.
