CONSTRUCTION WASTE MATERIAL SORTING DEVICE HAVING DAMPING COIL SPRING, INTEGRATING COIL SPRING BODY AND NOISE PREVENTIVE MEMBER BY INSERT MOLD

摘要

PURPOSE: A construction waste material sorting device having a damping coil spring is provided to absorb shock by supporting a vibration screen and to prevent vibration by integrating noise preventive members with upper and lower ends of a coil spring body by an insert mold. CONSTITUTION: A construction waste material sorting device having a damping coil spring(A) is composed of a filtering net(13) obliquely installed at an upper part of a frame(11); a vibration screen(1) for transferring construction waste materials supplied to the filtering net by a vibration unit(14); a guide chute(12) installed at a lower part of the vibration screen to supply earth and sand filtered by the filtering net to a transfer conveyor(2); a blowing duct(32) connected with a blower(31) of a blowing unit(3) and communicate-installed at a front end of the guide chute; an intake duct(42) connected with an intake box(43) and an inhaler(41) of an intake unit(4) and communicate-installed at the opposite side of the blowing duct; and the damping coil spring disposed between the frame and the vibration screen to support the vibration screen. The damping coil spring is formed by integrating a ring-shaped body and a noise preventive member by an insert mold. The body is made from one of steel, phosphor bronze, and nickel alloy and the surface is not separately coated. The noise preventive member is made from synthetic resin and formed at the upper and lower ends of the body.
