The invention discloses a pesticide spraying unmanned aerial vehicle device with a rotatable spray head. The device comprises a fuselage, wherein four groups of uniformly distributed flying devices are fixedly mounted in the fuselage, a liquid medicine storage box is fixedly mounted on the upper end surface of the fuselage, a liquid medicine storage cavity is formed in the liquid medicine storagebox, a liquid medicine adding pipe and a liquid medicine adding port are fixedly mounted on the liquid medicine storage box, and a liquid medicine adding valve is fixedly mounted on the liquid medicine adding pipe; the support leg frame of the device can be contracted, the wind resistance of the unmanned aerial vehicle in the flight process is reduced, the cruising ability of the unmanned aerial vehicle is enhanced, meanwhile, a damping device is arranged in the device, so that the impact to the unmanned aerial vehicle is greatly reduced when landing, and safety of precise instruments in the unmanned aerial vehicle is ensured. In addition, the device uses reverse thrust of liquid medicine spraying as power for rotation of the spray head, so that the spray head can rotate to spray medicine,the spraying area of the unmanned aerial vehicle during linear flight is increased, and the working efficiency of the unmanned aerial vehicle is improved.

    一种喷头可旋转的喷药无人机装置,包括机身,所述机身内固定安装有四组均匀分布的飞行装置,所述机身上端面固定安装有药液储存箱,所述药液储存箱内设置有药液储存腔,所述药液储存箱上固定安装有药液添加管与药液添加口,所述药液添加管上固定安装有药液添加阀门;本装置的支脚架可以收缩,减小无人机在飞行过程中的风阻,提高无人机的续航能力,同时装置内设置有减震装置,使得无人机在降落时受到的冲击大幅减少,保证无人机内精密仪器的安全,另外本装置利用药液喷洒的反推力作为喷头旋转的动力,使得喷头可以旋转喷药,使得无人机直线飞行时喷洒的面积变大,提高无人机的工作效率。
