PROBLEM TO BE SOLVED: To provide a structure, by which it can be prevented that particulate matters adhered near an exhaust port of a transportation pipe become a large lamp and drop, in a feeder which feeds the particulate matters by rotation of a screw. ! SOLUTION: A feeder 1 transports particulate matters to an exhaust port 41 side by rotating a screw 50 disposed in a transportation pipe 40. Further, this feeder 1 has a scraping-off part 80 which scrapes off the particulate matters from a surface near the exhaust port 41 of the transportation pipe 40. The scraping-off part 80 is disposed in approximate with an outer peripheral surface, an inner peripheral surface, or an end face of a transfer direction downstream side of the transportation pipe 40 and near the exhaust port 41 of the transportation pipe 40. When the scraping-off part 80 is rotated, the particulate matters are scraped off from the surface near the exhaust port 41 of the transportation pipe 40. Consequently, it can be prevented that the pa |
