PURPOSE:To collect the staying dust on a belt conveyor, by setting up a snub pulley body made up in grid cylindrical form to be rotatable at the outward part of a suction pipe having a dust suction port at its upper part and being connected to a suction pump. CONSTITUTION:When a conveyor 4 is driven, a snub pulley body 1 is also rotated on a suction pipe 6 according to the movement of a belt 4'. If the dust sticking to the belt 4' reaches the snub pulley body 1 after going around the return side, a round bar 3 acts as scraping a part of the dust off the body 1. In addition, since a port 8 for the suction pipe 6 comes close to the inner wall part of the body 1 and thereby is being extended in a chute form, the dust sticking to the belt 4' is sucked in as it is swallowed up by the flow of air from space between each round bar 3 and each ring member 2. |
