When the conveying line 42 needs to be lifted, the first power source 433 drives the supporting shaft 431 to ascend, so that the first chain wheel 432 ascends to drive the second ends of the two first chains to ascend, then one side of the conveying line 42 connected with the first chain wheel is driven to ascend, the other end of the conveying line 42 synchronously ascends under the action of the second chains, the second chain wheel and the third chain wheel, and the whole conveying line 42 is finally lifted; when the conveying line 42 is required to be lowered, the first power source 433 only needs to drive the supporting shaft 431 to be lowered.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
