The invention relates to the technical field of unmanned aerial vehicles, and discloses a plant protection unmanned aerial vehicle which comprises a vehicle body, sprayers used for spraying pesticides are arranged on the lower portions, close to all wings, of the vehicle body, a pesticide barrel is arranged on the lower portion of the middle of the vehicle body and communicates with the sprayers through a guide pipe and a pump body, and a plurality of undercarriages are further arranged on the lower portion of the vehicle body. A spherical groove is formed in the lower portion of the machine body, an opening groove is formed in the lower portion of the groove in a penetrating mode, the ball is arranged in the groove and movably connected with the inner wall, the exposed spherical portion of the ball is an inferior arc under the horizontal projection, and the connecting column is vertically connected to the lowermost portion of the ball through a vibration isolation assembly. The open groove is in a circular truncated cone shape with the upper portion narrow and the lower portion wide, the connecting column is arranged in the open groove, and the lower end of the connecting column is connected with the pesticide barrel. By means of the gravity of the pesticide barrel and the relation between the ball and the groove, shaking of pesticide in the pesticide barrel when the machine body deflects in angle is reduced, and the influence of shaking of the pesticide on control of the machine body is reduced.

    本发明涉及无人机技术领域,公开了一种植保无人机,包括机体,机体靠近各个机翼的下方均设置有用以喷洒农药的喷头,机体的中部下方设置有药桶,药桶通过导管以及泵体与喷头连通,机体的下方还设置有多个起落架,机体下方的内部开设有球形的凹槽,凹槽的下方贯通开设有开口槽,还包括:球体、连接柱,球体置于凹槽内且与内壁活动连接,球体露出的球面部分水平投影下为劣弧,连接柱通过隔振组件竖直连接于球体的最下方,开口槽呈上窄下宽的圆台形,连接柱置于开口槽内,连接柱的下端与药桶相连接。本发明通过依靠药桶的重力以及球体与凹槽的关系,来降低机体发生角度偏转时药桶内农药的晃动,降低了农药晃动对机体的控制造成影响。
