ABSTRACT:
A hopper subjected to a suction effect of a vacuum source such as a vacuum pump is connected by a hose to a suction nozzle thrown into a container for grainy material and an ejector is provided to supply the suction nozzle with pressurized air, and thereby a smooth pneumatic conveyance of the grainy material is achieved. A cap laterally provided with openings is slidably put on an open end of the suction nozzle and a total opening area of the lateral openings is adjusted by axially sliding the cap on the open end of the suction nozzle.
