As a means for pushing the upper portion of the movable screen upstream, for example, in Japanese Utility Model Publication No. 7-56336, a side surface of a substantially elongated slider is disposed on the side of the horizontally long base at the front portion of the scratching plate. The movable screen is configured to be pushed open by rotation.

  Since the kamaboko slider is a plate body, it is excellent in rigidity and durability, but the front and rear intermediate portions protrude in a kamaboko shape, and a toothed plate is disposed on the upper part. On the other hand, the swinging guide plate of the movable screen has a substantially rectangular shape on the side surface. Therefore, when the slider and the projecting portions of the swinging guide plate are in contact with each other, there is a toothed plate above the movable screen, Since a gap is generated between the lower part of the tooth plate and the upper part of the movable screen, dust may be caught. Further, when the endless chain is slackened at the upper bent portion of the circulation guide rail, there is a problem that the rake descends by weight and contacts the fixed apron.

  In the dust removing device of the dust removing apparatus according to the present invention, rollers are provided on the upper and lower front portions of the side plates provided on both sides of the horizontally long base. The specific contents of the invention are as follows.
