とが接触することは絶対にない。[Operation of First Embodiment of the Invention] Next, the operation of the first embodiment of the invention will be described. During weighing, the sliding cylinder 25 is separated from the transport pipe 15 by its own weight, that is, the weighing hopper 6 is completely cut off from the transport pipe 15. Therefore, the weighing can be performed accurately. In addition, at the time of weighing, the rising portion 10a moves downward with respect to the falling portion 15a,
That is, since the rising portion 10a does not move laterally with respect to the falling portion 15a, the sliding tube 25 and the falling portion 15a
There is absolutely no contact with.

することが出来る。After the measurement is completed, when the suction device 22 is operated to transport the raw material for granular material, the air above the measuring hopper 6 passes through the gap between the raw material for granular material in the measuring hopper 6. Is sucked into the suction device 22 and the outside air is sucked into the suction device 22 through the gap 13, and the outflow short pipe 1
0 and a flow of air toward the stirrer 19 is generated in the transport pipe 15, and the raw material for granular material rides on the flow to reach the stirrer 19. The sliding tube 25 comes into contact with the end of the inlet 16 of the transport pipe 15 when the flow resistance portion 27 is pushed by the flowing air and the flowing granular material as described above. As a result, since the gap 13 is almost closed and the outside air hardly enters from the gap 13, it is possible to increase the transporting power of the granular material as compared with the case where the gap 13 is not closed.

とが出来る。When the raw material of the granular material is clogged in the short outflow pipe 10 or the transportation pipe 15, the flow velocity of the raw material of the granular material is lowered, and as a result, the sliding cylinder 25 is moved from the transportation pipe 15 by its own weight. A gap 13 is formed between the short outflow pipe 10 and the transport pipe 15, and outside air is introduced from the gap 13 to reduce the density of the raw material powder in the pipe. The clogging can be cleared automatically.

That is, the outlet 11 side portion of the outflow short pipe 10 is horizontal, and the inlet 16 side portion of the transport pipe 15 is horizontal. The sliding cylinder 25 is urged in a direction away from the transport pipe 15 by a weak spring 29. The operation of the second embodiment of the invention is the same as that of the first embodiment except for the following points, and thus the description thereof is omitted. The sliding cylinder 25 is positioned away from the transportation pipe 15 by the spring 29 in the state where the raw material for granular material is not transported.

In short, the means for moving the sliding cylinder 25 away from the transport pipe 15 in the state where the powdery or granular material is not transported may be any one of the weight of the sliding cylinder 25 and the spring.
