(Prior art and its problems) In general, a speed sprayer ejects a chemical from a spray nozzle and spreads the chemical over a wide area, for example, in the side and upper spaces, by airflow caused by moving blades in a wind tunnel. It is distributed radially.

しかし、散布対象である果樹の種類や大きさ、
散布時期によつて散布量を調整することが必要と

Therefore, the spray plate in the nozzle body of the spray nozzle at a predetermined location is used as a blind plate to block the ejection of the medicine from the nozzle and adjust the overall spray amount. However, each spray nozzle must be disassembled and the spray plate replaced, which is a cumbersome task, and there are problems such as the spray plate being lost.

In addition, there is also one in which each spray nozzle is provided with an opening/closing knob to open and close the spray nozzle. However, since the spray nozzle is screwed onto the piping path, the positions of the opening/closing knobs may be uneven, and the operation of the opening/closing knobs may be troublesome. In addition, there are other problems such as the opening and closing mechanism blocking the airflow and narrowing the spraying range.

Furthermore, there is also a device in which the spray nozzle group is divided into a plurality of nozzle groups, and the chemical liquid is sprayed and cut off for each nozzle group. However, since the switching is done for each nozzle group, it is not possible to make delicate adjustments to the overall spray amount. Further, there are problems such as the piping system becoming complicated.
