Automatic slag scraping device of cast-weld machine

The utility model relates to the technical field of cast-weld machines, in particular to an automatic slag scraping device of a cast-weld machine, which comprises a cast-weld machine body, a moving mechanism is fixedly connected to the inner wall of the cast-weld machine body, and a slag scraping mechanism is fixedly connected to one side, far away from the inner wall of the cast-weld machine body, of the moving mechanism. A slag scraping mechanism is arranged on the inner wall of the cast-weld machine body, a collecting bin is fixedly connected to the inner wall, located beside the moving mechanism, of the cast-weld machine body, and the moving mechanism is matched with the collecting bin to clean waste slag on the slag scraping mechanism into the collecting bin. And meanwhile, the problem that operation risks exist in manual slag removal operation is avoided, the arranged moving mechanism can drive the slag scraping mechanism to move relative to the collecting bin, the lead slag on the slag scraping mechani
