Intelligent spraying device for pesticide application robot and spraying method thereof

A spraying method of an intelligent spraying device for a pesticide application robot, the spraying method comprising:

• acquiring wind direction information of a current spraying operation area;
• presetting a wind direction indicator standard and establishing a database, and storing the wind direction indicator standard in the database to generate a wind direction indicator standard database;
• decomposing the wind direction information into one-dimensional direction information to generate one-dimensional vector information;
• importing the one-dimensional vector information into the wind direction indicator standard database for comparison to generate a deviation rate;
• if the deviation rate is greater than a preset deviation rate, generating adjustment information, and transmitting the adjustment information to a control terminal for a spraying device,
• after transmitting the adjustment information to the control terminal for a spraying device, starting the spraying device, allowing a second driving motor to drive a conveying tube to rotate for a preset number of turns, wherein a through hole of a preset size of the conveying tube directly faces a transport tube;
• a spraying liquid entering the conveying tube through a liquid inlet pipe, passing through the through hole of the preset size of the conveying tube, and then entering the transport tube, wherein a first driving motor on the transport tube rotates to a preset angle based on the wind direction information;
• and
• after the first driving motor rotates to the preset angle, arc-shaped fan blades rotating to a preset angle to spray the spraying liquid out of a gap between the arc-shaped fan blades for acting on crops, thereby completing spraying operation.
