Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control helicopter used for aerial spraying of chemicals or fertilizers.

[0002]

Conventionally, when a fertilizer of a self-spreading granule such as 1 kg, which is mounted on an unmanned helicopter, is continuously sprayed in the air, the spraying amount is small and the spraying is limited to a predetermined area. There is an inconvenience that it can only be done. If continuous spraying is stopped and the one-shot spraying is applied to a predetermined area with a small spraying amount per spray, the spraying amount for each spray will vary greatly due to individual differences among operators. There was a problem.

[0003]

Therefore, the present invention is a remote control helicopter in which a tank is mounted on an unmanned helicopter and a granular substance such as granular chemicals or fertilizer is sprayed in the air. One-shot means for spraying in the air is installed in the remote control device to effectively spray a small amount of particulate matter to be mounted on the unmanned helicopter over a predetermined area, and to effectively spray particulate matter such as chemicals using the remote control helicopter. To improve.

Also, after a certain time has elapsed from the opening operation of the spraying shutter for spraying the granular material, the shutter is closed and
This enables accurate spraying by quantifying the opening operation time of the spraying shutter and improves spraying accuracy.

Furthermore, in a remote control helicopter in which a tank is mounted on an unmanned helicopter and granular materials such as granular chemicals or fertilizer are sprayed in the air, a remote control device is provided with an alarm unit for notifying the timing of the opening / closing operation of a spray shutter. The timing of the opening / closing operation of the spraying shutter is accurately notified to the operator so that the spraying amount per one time or the fertilizer is stably maintained and the spraying accuracy is improved.
