An upper side hopper 41 is arranged over the lower side hopper, and the resultant body is attached to the tip of a rod 39 of the air cylinder through an attachment member 45. In the inner side of the upper hopper, a hub 57 and a spoke 59 extending outward from the hub 57 and connected to the inner periphery of the upper hopper are provided. An opening/closing valve stem 51 of an opening/closing valve 49 is inserted into a hole of the hub and fixed.
