Slag salvaging device capable of achieving flat digging

The utility model relates to the technical field of slag salvaging equipment for aluminum electrolysis production, in particular to a slag salvaging device for realizing flat digging, which comprises a fixing frame, a driving rod with the middle hinged on the fixing frame, a slag digging mechanism arranged on one side of the driving rod, and a driving device arranged between the other end of the driving rod and the fixing frame. Through the arrangement of the four-connecting-rod mechanism II and the four-connecting-rod mechanism I, in the opening and closing process of the left grab bucket and the right grab bucket, the sharp ends of the bottoms of the left grab bucket and the right grab bucket basically move horizontally, no blind area exists in slag salvaging, all-directional block salvaging is achieved, and the situation that the grab buckets need to be lowered for salvaging residues in an anode scrap pit completely is effectively avoided. And in the slag salvaging process, the slag salvaging device damage
