The invention relates to the related technical field of unmanned aerial vehicles, and discloses a plant protection unmanned aerial vehicle, which comprises a rack, an undercarriage, a battery, a pesticide storage box and an avionics module, a power assembly is installed on the rack and comprises a vehicle arm and wings, and a spray head assembly is installed on the vehicle arm; The distance between the nozzle assemblies on the two sides in the advancing direction of the unmanned aerial vehicle is larger than that between the nozzle assemblies on the same side. Through the design that the distance between the left and right wings is larger than the distance between the front and rear wings, the effective spraying width is improved, the spraying work efficiency is improved, and the length of a machine arm does not need to be excessively increased. That is to say, under the condition of the same effective spraying width, the unmanned aerial vehicle is smaller in size and convenient to carry and transport. By means of the design that the distance between the left wing and the right wing is larger than the distance between the front wing and the rear wing, the rotational inertia of the unmanned aerial vehicle in the flight direction is smaller, and the tilt angle speed of the unmanned aerial vehicle can be increased and the braking distance can be reduced when braking is executed; in the same way, the acceleration capacity can be improved during acceleration.

    本发明涉及无人机相关技术领域,公开了一种植保无人机,包括机架、起落架、电池、储药箱和航电模块,机架上安装有动力总成,动力总成包括机臂和机翼,机臂上安装有喷头组件,无人机前进方向两侧的喷头组件之间距离大于同侧的喷头组件之间距离,通过使左右机翼之间距离大于前后机翼之间距离的设计,提高了有效喷幅,进而提高了喷洒工作效率,而且不必过多的增加机臂长度,也就实现了相同有效喷幅情况下,本申请中的无人机体积更小,便于携带和运输;通过使左右机翼之间距离大于前后机翼之间距离的设计,使无人机在飞行方向上的转动惯量更小,可以在执行刹车时,提高无人机的倾转角速度,减小刹车距离,同理,也可以在加速时提高加速能力。
