摘要：PURPOSE: A belt conveyor pulley containing an exhaust port is provided to prevent the belt conveyer from carrying caused by rainwater infiltrating inside of the belt. CONSTITUTION: A belt conveyor pulley comprises an absorbing hole(5) formed on a surface of a lagging(23) of a pulley; an exhaust port mounting a lower portion of an exhaust plate(7) of a circular shape on inside of the absorbing hole; a sidewall(22) installed on a side face of a drum(21); and plural ventilated holes(11a,11b,11c,11d). The exhaust port is vertically formed to rotate the belt with the pulley. Then, air is absorbed to the absorbing hole and discharged through the exhaust port and the exhaust plate. The air is discharged to the ventilated hole installed on the sidewall. Thereby, the belt conveyor pulley prevents the belt from sliding in raining by generating adsorptive force in the pulley while maintaining small pressure than atmospheric pressure. The belt wound to the pulley of the belt conveyor is not slid to smoothly operate carrying work.
