PURPOSE:To prevent dust from accumulating in spaces between the side plates of a cover and the side walls of a conveyer by disposing scraping plates moving with the conveyer in a body in the spaces. CONSTITUTION:Dust transported by a conveyer apparatus 4 are dropped through gaps between side plates 18 and a floor to collect and accumulate in spaces 20, 20. The spaces 20, 20 are covered with scraping plates 19, which are moved with a conveyer 5 in a body, so that dust collcted in the spaces 20, 20 is scraped forward by the scraping plate 19 to prevent dust from dropping through the spaces. |
