Cleaning device for terbium oxide rare earth production line

The utility model relates to the technical field of terbium oxide, in particular to a cleaning device for a terbium oxide rare earth production line. Guiding outer frames are symmetrically placed at the two ends of the cleaning scraping plate, fixedly-connected inner sliding plates are symmetrically arranged at the two ends of the cleaning scraping plate, one ends of the inner sliding plates are located in the guiding outer frames on the same side, and locking guide columns connected in a buckled mode transversely penetrate through the middles of the guiding outer frames. The locking guide column penetrates through one end of the inner sliding plate, and the locking guide column is sleeved with a jacking spring. Residual rare earth on the conveying belt can be cleaned by means of the cleaning scraping plate, meanwhile, the cleaning scraping plate can be better attached to the outer surface of the conveying belt by means of a jacking spring and a locking guide column, in addition, in the rotating process of th
