The invention discloses an airborne spraying device of an unmanned aerial vehicle. The airborne spraying device comprises an exhaust turbine, an air inlet turbine and a powder bin. The exhaust turbine is connected with an engine exhaust funnel of the unmanned aerial vehicle, and waste gas exhausted from the engine exhaust funnel pushes the exhaust turbine to rotate; the air inlet turbine is connected with the exhaust turbine, the exhaust turbine drives the air inlet turbine to rotate synchronously, and an exhaust pipeline of the air inlet turbine is connected with the powder bin in a sealed mode. The powder bin is provided with a powder outlet pipe, a catalyst is contained in the powder bin, and the catalyst is driven by compressed air generated by the air inlet turbine to be discharged from the powder outlet pipe. The device pushes the gas inlet turbine to suck gas flow through engine tail gas and then drives a catalyst or moisture absorption particles to be sprayed into cloud, frequent replacement of a gas cylinder is not needed, and the cost is saved; the device is reasonable in structure and easy to install, long-term use of equipment can be met only by simply modifying an engine, a gas cylinder does not need to be hung, the weight of the gas cylinder is reduced, and more catalysts or moisture absorption particles can be carried.

    本发明公开了一种无人机机载喷撒装置,该装置包括排气涡轮、进气涡轮以及粉仓;排气涡轮与无人机的发动机排气筒连接,发动机排气筒中排出的废气推动排气涡轮转动;进气涡轮与排气涡轮连接,排气涡轮带动进气涡轮同步转动,进气涡轮的排气管道与粉仓密封连接;粉仓设置有出粉管,粉仓内装有催化剂,催化剂通过进气涡轮产生压缩空气带动从出粉管排出。该装置通过发动机尾气推动进气涡轮吸入气流后带动催化剂或吸湿粒子喷向云中不用频繁更换气瓶,节省成本;该装置结构合理,安装简单,只需要需要简单改装发动机即可满足设备长期使用,不需要挂载气瓶,减少了气瓶的重量可多携带催化剂或吸湿粒子。
