DUSTPROOF DEVICE FOR BELT CONVEYOR

摘要

PROBLEM TO BE SOLVED: To prevent dust in a material to be carried in a relaying part from scattering without causing high cost. SOLUTION: A dustproof box 30 having a shape to cover a conveyor belt 10 is provided on a downstream side of a skirt 33 of the relaying part 20 by being connected with a skirt carrier port. The inside of the dustproof box is partitioned by at least one of dust interference devices 33, 33' and 33". Dust in the air blown from the carrier port is made to interfere with the dust interference devices 33, 33' and 33" and is dropped on the conveyor belt 10. It is desirable that a plurality of dust interference devices are provided in a belt carrying direction and flow velocity of air is lowered every time passing each of the dust interference devices.
