CHUTE DIVICE FOR BLOCKING DUST

摘要

PURPOSE: A chute device for blocking dust is provided to minimize time and costs for displacing a chute by displacing not the entire chute but a damaged part when the chute gets damaged because the chute is formed into a flange part and a connection pipe to be detachably coupled. CONSTITUTION: A chute device for blocking dust comprises a winding device, a chute part, and a lower support. The winding device winds and releases a wire rope. The chute part is downwardly extended from the bottom of the winding device and multiple cone shaped chutes are connected to the chute part into a telescopic shape. The lower support is installed at the lowermost end of the chute part, and the upper end of the lower support is fixed in the wire rope connected to the winding device. The chute is comprised of a flange part(210) in the upper end and a connection pipe(220) detachably installed under the flange part.
