THE LIGHT SEPARATOR FOR AN EXTRANEOUS SUBSTANCE OF THE CONSTRUCTION WASTE USING THE VIBRATION PLATE

摘要

A device for sorting light foreign materials of the construction waste by a vibration plate is provided to effectively separate the light foreign materials with occupying a small space by installing the vibration plate in a sorting device body in multiple stages and to reduce noise by preventing the crushed material from directly coming into contact with the surface of the vibration plate. The device for sorting light foreign materials of the construction waste by a vibration plate(10) is composed of plural vibration plates combined in a sorting device body equipped with a vibration generating unit; a blower mounted between the vibration plates to supply the air; a light material discharge port and a heavy material discharge port combined in the lower side of the sorting device body; first hinge grooves(102) bored through both sides of a plate(101) having an opened lower side of the vibration plate and joined to a fixing plate(104) by fitting a hinge shaft(103); and the fixing plate combined with hinge pieces(105) having a second hinge groove(106), at both sides, wherein both lower sides of the fixing plate are combined in the sorting device body. The first hinge grooves formed at both sides of the plate are inclined from the middle side to one side. A rib(108) having a third hinge groove(107) is combined to the lower side of the plate. A stop ring(109) is joined to stop grooves(103a) formed at both ends of the hinge shaft.
