PURPOSE:To prevent the breakage of a dust remover when a large-size rubbish is bitten by connecting a rake arm and an elevating driver by means of plural leaf springs arranged in parallel with one another in the far and near direction in relation to a screen. CONSTITUTION:When actuating a driver 20, a pinion 18 is turned, a driving portion 17 goes up along the rising path 7a of a guide path 7, a rake arm 9 goes up through leaf springs 22a and 22b, a rake-up portion 10 goes up along a screen 2, and dust is raked up. When large-size rubbish S is bitten, the leaf springs 22a and 22b are deformed, the rake arm 9 is moved around the guider 11 in a rocking manner in such a way that the rake-up portion 10 is separated from the screen 2, and thereby the degree of biting is eased. The driving portion 17 goes up, the cam 15 of a wiper arm 12 is coupled with a roller 16, the wiper arm 12 is moved in a rocking manner, and dust S is pushed out toward a chute 4 by means of a scraper 14 and dropped into a discharge portion 5. |
