The driving shaft member 2 of the cleaning device is laid in parallel above the lower layer of the chain in a direction perpendicular thereto. In this case, in order to secure the structural strength of the cleaning blade 21, reinforcing plates may be attached to both sides of the end portion connected to the driving shaft member 2. The width of this gusset plate needs to keep cleaning the exposing of end to avoid the gusset plate to cleaning the increase of end width, in order to guarantee to clean the operating strength of the terminal to the viscidity material on the lower floor chain, provide the guarantee to the clean effect of lower floor chain. The two ends of the driving shaft 2 penetrate through the scraper casing 1 and extend to form a first control end 22 and a second control end 23. In order to ensure the connection quality and the rotation driving effect, a corresponding bearing structure can be arranged between the driving shaft 2 and the scraper machine shell 1, and a sealing element 3 is sleeved on the outer side of the scraper machine shell 1. The metal shell of the sealing member 3 is sleeved on the first control end 22 and the second control end 23 and surrounds the outer surface of the scraper casing 1 to form a sealing cavity.
