Abstract

PURPOSE:To favorably clean a pothole by rotating a brushing apparatus to the same direction as rotation of a rotary sorting cylinder and also rotating the brushing apparatus at the circumferential velocity close thereto. CONSTITUTION:Both a rotating shaft 36 and a brushing roll 35 are rotated at nearly same velocity as a rotary sorting cylinder 11 to the same direction while the tip part of the brushing roll 35 is brought into contact with the potholes 11a, 11a... of the rotary sorting cylinder 11 and thereby cleaning operation of the potholes is performed. In this case, since both the rotary sorting cylinder 11 and the brushing roll 35 are rotated to the same direction, the time when the brushs 43 are allowed to correspond to the potholes 11a and rotated is prolonged and also the time when the brushs 43 curved before being introduced into the potholes 11a are extended can be prolonged. Therefore the brushs 43 are extended and the bottom parts of the potholes 11a are favorably cleaned.
