Abstract
A suction nozzle device includes a large-diameter pipe, a large-diameter nozzle, a small-diameter pipe, a small-diameter nozzle, and a support mechanism for supporting the large-diameter and small-diameter pipes so as to be movable relative to each other. As the large-diameter and the small-diameter pipes move relative to each other, the large-diameter nozzle and the small-diameter nozzle selectively protrude. A nozzle can be selected from nozzles having different diameters, and the flow rate can be varied in accordance with the selection of the nozzle.
