The invention discloses a plant protection unmanned aerial vehicle with a large-range pesticide spraying and fertilizing function, and particularly relates to the technical field of plant protection unmanned aerial vehicles; the plant protection unmanned aerial vehicle comprises an unmanned aerial vehicle body, a liquid storage tank is fixedly connected to the lower surface of the unmanned aerialvehicle body, and a first bearing is clamped to the lower surface of the liquid storage tank; a connecting cylinder is arranged in the first bearing in a sleeving mode; and two limiting grooves are formed in the inner wall of the connecting cylinder. According to the plant protection unmanned aerial vehicle, a driving device, a limiting groove, a threaded column, a spray head, a positioning rod and a limiting strip are arranged, and a plurality of nozzles are formed in the surface of the spray head, so that the plant protection unmanned aerial vehicle can quickly spray pesticide in the using process, and the spray head can quickly rotate under the action of a positioning column, a limiting strip and a limiting hole; and thus the spraying range of the pesticide in the spraying range is increased substantially. Due to the fact that the spray head rotates by 360 degrees, dead corners are not prone to being reserved in the pesticide spraying process of the plant protection unmanned aerialvehicle, and the pesticide utilization efficiency of the plant protection unmanned aerial vehicle is guaranteed.

    本发明公开了具有大范围农药喷洒施肥功能的植保无人机,具体涉及植保无人机技术领域,包括无人机体,所述无人机体的下表面固定连接有储液箱,所述储液箱下表面卡接有第一轴承,所述第一轴承内套接有连接筒,所述连接筒的内壁开设有两个限位槽。本发明通过设置驱动装置、限位槽、螺纹柱、喷头、定位杆和限位条,由于喷头的表面开设有若干个喷口,使得该植保无人机在使用过程中可以快速对农药进行喷洒,且在定位柱、限位条和限位孔的作用下,使得喷头可以快速转动,从而大大提高了农药在喷洒过程的喷洒范围,由于喷头三百六十度旋转,使得该植保无人机在喷洒农药过程中不易留有死角,且保障了该植保无人机的农药利用效率。
