May be applied. In this case, there is an advantage that the inside of the transport pipe is harder to be clogged than in the past. Further, the pneumatic transport device 1 of the present invention may be applied to a small fish collection device. In this case, the small fish that is the transported object is hardly damaged, and can be recovered while maintaining the shape. In these cases, there is no need to provide the delivery tube 10 with the hole 10a.

In the above embodiment, the diameter of the delivery pipe 10 at the connecting portion 11 is made larger than that of the suction pipe 9, but as shown in FIG. The diameter may be large, or the right end of the suction pipe 9 may be connected to the delivery pipe 1.
The gap 12 may be provided with a smaller diameter than the left end of the zero. Further, instead of the hole 10a, a socket 19 of a different diameter is attached to the outlet 3 as shown in FIG.
