ABSTRACT:
A belt cleaner is provided in which a scraping portion of a scraper becomes in contact with the belt surface over the full width thereof even when the trough-shape of the belt surface is different from the shape as expected, thereby the leavings on the belt surface will be scraped off in an optimum manner. The scraper is formed by a resiliently deformable blade which is curved and held in a holding groove of a holder so that the scraper (5) keeps an arcuate shape having a distance (L) between the central portion and the both side portions thereof with respect to the lengthwise direction of the belt. Shape shifting means (20) is provided in the holding groove (13) for transforming the scraper (5) into a desired curved configuration selected from among plural curved configurations changing the distance (L) thereby the scraper (5) is held in the selected curved configuration.
