DUST SHIELDING DEVICE FOR CARGO-HANDLING HOPPER

摘要

PURPOSE: A dust shielding device for a cargo-handling hopper is provided to prevent waste of water and environmental contamination, while eliminating the necessity of using an additional device for water spray. CONSTITUTION: A dust shielding device comprises a cross-shaped rotation blade(100) having a plurality of blades(110) arranged in a radial direction, wherein each blade has a cut-out part(130) formed at an end of each blade, and the cross-shaped rotation blade has a coupling hole(120) formed through the center of the cross-shaped rotation blade; a rubber plate(150) fitted into the cut-out part of the blade and coupled through a bolt(160); a rotation shaft(200) secured into the coupling hole of the cross-shaped rotation blade through a bearing(140); and a plurality of plummer blocks(300) arranged at the top of a hopper in such a manner that the plummer blocks permit the rotation shaft to rotate.
