[0041] When working, after using the salvage device for many times, the electrolytic aluminum slag adhered in the salvage tank claw 18 is difficult to clean due to air cooling, at this time, the first telescopic rod 11 and the second telescopic rod 12 are lowered, the connecting block 31 contacts the ground, when the connecting block 31 contacts the ground, the connecting block 31 is driven by the pressure of the ground to make the connecting plate 32 close to the outer side wall of the salvage tank claw 18, the pressure block 33 is inserted into the slot 19 to push out the electrolytic aluminum slag adhered in the salvage tank claw 18 for cleaning, this step facilitates the cleaning of the electrolytic aluminum slag in the salvage tank claw 18, reduces the blockage in the salvage tank claw 18, and increases the salvage efficiency.

[0042] When working, when it is necessary to adjust the direction of the salvage device, another telescopic device 21 can be lifted, then the second rotating rod 6 is rotated to turn the salvage device, this step can adjust the direction of the telescopic device 21 to increase the flexibility of the salvage device, so that the electrolytic aluminum slag can be cleaned more effectively.
