Surface, especially on the scraping piece support projection 11b, the support projection 11b has elasticity, so that at the start of the scraping of the adhered material, bending occurs in the circumferential direction, and the adhered material is bent. At the end of the scraping, a deformation operation is performed in which the bent state causes a reverse bending in the circumferential direction, and even if attached, the attached matter is immediately shaken off, scraped off, and deposited on the surface of the support protrusion 11b. Therefore, it is possible to prevent the occurrence of a problem that the scraping pieces 12 are buried by the deposits and do not perform the scraping function.

[0007] At this time, the scraping piece supporting projection has a substantially T-shaped cross section, and the circumferential width of the distal end portion is wider than the circumferential width of the base portion. The scraping piece can be securely attached to the tip.

In addition, the scraping piece supporting projection can be easily bent at the time of the scraping operation of the adhering material around the base, so that an efficient scraping operation utilizing the elastic restoring force can be performed.

Further, even if the scraped-off deposits accumulate between the adjacent supporting projections, the spacing between the bases of the supporting projections can be kept wide, so that each supporting projection can be secured. The bending operation of the piece can be satisfactorily ensured, and from this point as well, the efficiency of scraping off the attached matter can be improved.

Further, the rotating body is formed by arranging a plurality of rotating divided bodies coaxially on a rotating shaft, thereby increasing or decreasing the number of rotating divided bodies to reduce the width of the rotating body to the width of the belt body. And the removal of the deposits on the belt body by the rotating body can be ensured.
