The discharge ports 20 and 21 are directed downward in the transport airflow. The jet heads 4 having the same configuration are attached to the vertical cylindrical portions 16 and 19 of the jet head mounting tubes 13 and 14, respectively. The transport airflow sent into the injection pipe main body 22 is jetted downward from the discharge ports 20 and 21 via the jet head 4.

An airflow collision surface 24 for receiving the transport airflow is provided. The airflow collision surface 24 is provided near the leeward edge of the intermediate discharge port 20 so as to face the carrier airflow flowing in the horizontal cylindrical portion 15 of the intermediate jet head mounting pipe 13. A part of the carrier airflow flowing in the horizontal cylindrical portion 15 of the intermediate jet head mounting pipe 13 collides with the airflow collision surface 24, and the blowing direction of the colliding carrier airflow is changed downward. As a result, along with the transport airflow that is discharged downward, the scattered matter contained therein is ejected downward from the intermediate discharge port 20.

て、散布量の均一化を図ることができる。Generally, the magnitude relationship between the ejection amount of the sprayed material from the intermediate ejection port 20 and the ejection amount of the spraying agent from the tip ejection port 21 (see FIG. 3) is determined by the air flow collision surface 24. It depends on the size of the area. Therefore, by setting the area of the airflow collision surface 24 to an optimum size, the amount of the sprinkled material discharged from each of the discharge ports 20 and 21 can be controlled, and the sprinkling amount can be made uniform.

ぼ下半部を流れる傾向がある。By the way, the sprayed products include powdery and granular ones. According to an experiment, it was found that these spatters contained in the carrier airflow flow inside the jet tube body 22 in different modes. That is, since the powdery scattered material is light in weight, it tends to be evenly mixed in the transport airflow and to flow evenly over the entire cross-section in the jet tube main body 22. On the other hand, since the granular spray is heavier than the powder, the spray tends to flow in substantially the lower half of the blowing section of the jet tube body 22.
