摘要： PROBLEM TO BE SOLVED: To provide a dust removing screen capable of removing a solid object such as dust caught by a screen bar easily.
SOLUTION: A dust removing screen 10 is provided with a screen bar 20 consisting of a frame body 11 and round bars 21A to 21N. An upper frame 12 is connected with right and left frames 14, 15 through support frames 14A, 15A. Many round bars 21A to 21N are arranged in parallel and in the longitudinal direction in the frame body 11, and upper ends of these round bars 21A to 21N are connected with the upper frame 12 through support members 21Au to 21Nu and the other ends thereof are connected with a lower frame 13. Spacers 30 are provided at a predetermined interval through support members 31 on the downstream side of a screen face 23. A clearance S
2 is formed between the screen face 23 and the spacer 30 and a clearance S
1 is formed between an upper part of the screen bar 20 and the upper frame 12 on the downstream side of the screen bar 20 so that a claw 41 of a scraping up device 40 passes along the screen bar 20 and escapes to the outside from the upper part of the screen bar 20.
