Zusammenfassung:	PROBLEM TO BE SOLVED: To solve problems of the conventional dust remover that when firm screen residue 12 is trapped by a screen bar, the top end of an advancing rake crawl 6B touches the firm screen residue 12 and can not advance any more, which operates a torque limiter attached to an actuator electric motor to stop the automatic operation of the dust remover. SOLUTION: In the dust remover having an arm 2, a rake 6, and a screen bar 1, the arm 2 can rotate around one end and the rake 6 is attached to freely move forward and backward to the other end of the arm 2. The rake 6 ascends as advancing along the screen bar 1 having an arc side face profile installed in the passage 14 and descends backward along the bar 1. COPYRIGHT: (C)2004,JPO
