In this case, the reciprocating pin 23, which has been pulled forward, is returned to the rear by the elastic restoring force of the spring member 24, and the rear end of the reciprocating pin 23, which is retracted, is the auxiliary guide bracket of the auxiliary running rail 37. Since it is inserted into 37a), a passage between the moving rail 35 and the moving rail 35 is closed by connecting the driving rail 36 and the auxiliary driving rail 37 with a reciprocating pin 23.

In addition, the horizontal bar (11b) of the cleaner frame (11a) is also raised with the rise of the cylinder member (11), the horizontal bar (11b) is the upper and lower guide brackets (33a) of the front support (34a) ( Since it interferes with the moving shaft 35 arrange | positioned between 33b), the said moving shaft 35 is raised to the upper part of the running rail 36, and the running wheel 35a assembled in the left and right both sides is carried out by the said running rail 36 ))

According to the present invention as described above, the driving chain is cyclically driven by using the traveling force of the belt that proceeds in one direction, and the second end of the second chain moving together with the driving chain being circulated and driven is closely fixed to the upper end of the belt. By moving horizontally to 1 cleaner side to remove the rainwater accumulated on the belt, it prevents chute blockage and equipment accidents caused by the freezing of rainwater during the winter season, and can significantly improve the transport efficiency compared to the prior art. Therefore, it is possible to prevent the fall of the raw material during transportation, pollution of the surrounding environment.
