[0002] Aluminum casting slag remover is an essential equipment for removing bottom sediment and floating objects on the surface of liquid from smelting furnaces, holding furnaces, mixing furnaces, etc. in large and medium-sized aluminum plants to improve the quality of aluminum ingots. The slag removal operation of domestic aluminum smelting furnaces generally uses manual and forklift-modified slag removal tools. The aluminum casting slag removal time is long, generally more than 30 minutes, the slag removal quality is low, the slag removal rake is greatly deformed, easy to damage, and has a large consumption; during the slag removal process, since the furnace door is open for a long time, not only a large amount of heat is lost, but also a high aluminum burn loss is caused, affecting the quality of the smelted metal, so there is The slag scraper truck is mainly composed of a traveling vehicle and a slag scraper structure mounted thereon. The slag scraper structure is composed of a telescopic arm and a lifting structure to drive a slag scraper head to perform slag scraping work. For example, the Chinese utility model patent with the authorization announcement number CN208443202U discloses a new type of slag scraper truck, which includes a vehicle body, a telescopic arm device arranged on the vehicle body, and a slag scraper head arranged on the telescopic arm device. The telescopic arm device is connected to the vehicle body through a composite lifting cylinder and a variable amplitude cylinder. However, the current slag scraper truck has the following defects:
