The invention discloses a pesticide spraying unmanned aerial vehicle with a course control function. The unmanned aerial vehicle comprises an unmanned aerial vehicle main body, a pesticide spraying mechanism and a springback prevention mechanism. The pesticide spraying mechanism comprises a liquid storage tank and a pesticide spraying rod, the springback prevention mechanism comprises a bearing plate and a plurality of fans, and when the unmanned aerial vehicle main body flies above crops, the pesticide spraying rod located at the front end can spray a pesticide liquid in the liquid storage tank into the air, the pesticide liquid can be attached to crop blades under the action of gravity and wind power of rotors of the unmanned aerial vehicle main body, and the blades can be twisted and deformed under the action of wind power. And in order to prevent the blades from springing back suddenly to bounce away the pesticide liquid, the multiple fans are arranged at the rear end of the unmanned aerial vehicle main body, the rotating speeds of the fans are sequentially decreased progressively. When the unmanned aerial vehicle main body leaves the blades, the multiple fans can continuouslyprovide wind power for the blades, and due to the fact that the wind power is decreased progressively, the blades can rebound slowly, an attachment rate of pesticide liquid drops is increased, and a pest control effect is guaranteed.

    本发明提供一种具有控制航向功能的喷药无人机,包括无人机主体、喷药机构以及防回弹机构,喷药机构包括储液箱以及喷药杆,防回弹机构包括承载板以及若干个风扇,无人机主体在农作物上方航行时,位于前端的喷药杆可以将储液箱中的药液喷洒到空中,在重力以及无人机主体旋翼的风力作用下,药液可以附着到农作物叶片上,而在风力作用下,叶片会发生扭曲形变,为了防止叶片突然回弹将药液弹走,在无人机主体的后端设置了若干个风扇,风扇的转速依次递减,当无人机主体离开叶片时,设置的多个风扇会持续对叶片提供风力,而由于风力递减,所以叶片会缓慢的回弹,提高药液滴的附着率,保证虫害防止的效果。
