The invention relates to the technical field of agriculture, in particular to an unmanned aerial vehicle pesticide spraying device, and aims to overcome the disadvantages that liquid pesticide in a pesticide kit is not full, and an unmanned aerial vehicle is easy to crash because of inertia dithering, and the disassembling and assembling of the pesticide kit in the unmanned aerial vehicle are complicated. The unmanned aerial vehicle pesticide spraying device comprises an unmanned aerial vehicle body, wherein an accumulator is fixed to the bottom of the unmanned aerial vehicle body through bolts; wiring frames are welded to the periphery of the unmanned aerial vehicle body; and a dual-shaft motor is fixedly mounted at the tail ends of the wiring frames through bolts. According to the unmanned aerial vehicle pesticide spraying device disclosed by the invention, the output end at the bottom of the dual-shaft motor is used as a power source of a peristaltic pump, the liquid pesticide in the pesticide kit is extracted by the peristaltic pump, and the sprinkling effect is realized through a spray nozzle; a buffer spring mounted in each compression fixing frame is used for pushing a corresponding rubber ball at the tail end of a corresponding supporting rod to slide in a corresponding clamping groove formed in the surface of the pesticide kit, so that the functions of buffering and clamping on the medical kit are realized, the situation of crashing caused by inertia dithering of the liquid pesticide in the medical kit is reduced, the disassembling and assembling of the medical kitare very convenient, and the working performance is improved.

本发明涉及农业技术领域，尤其涉及一种无人机农药喷洒装置,解决了药箱内药液未满易因惯性抖动导致无人机摔毁，且无人机药箱拆装复杂的缺点，包括无人机本体，所述无人机本体的底部通过螺栓固定有蓄电池，无人机本体的四周均焊接有接线架，所述接线架的末端通过螺栓固定安装有双轴电机，通过双轴电机的底部输出端用于蠕动泵的动力源，利用蠕动泵抽取药箱内的药液并通过喷头实现喷淋效果，通过压缩固定架内安装的缓冲弹簧推动支杆末端的橡胶球在药箱表面开设的卡槽内滑动，从而实现对药箱的缓冲和夹紧功能，减少因为药箱内部药液惯性抖动导致的摔毁情况，且拆装药箱非常方便，提高作业效率。
