The invention discloses an automatic pesticide spraying device of an unmanned aerial vehicle. The device comprises an unmanned helicopter and a pesticide spraying device, wherein the pesticide spraying device is fixed at the bottom of the unmanned helicopter; a second needle tube is communicated with a first needle tube; the bottom of the second needle tube is communicated with an annular tube; the inner diameter of the annular tube is the same as that of the second needle tube; a plurality of dividing balls are arranged in the annular tube at equal intervals; the dividing balls are connectedin series through connecting wires to form a closed ring; the first needle tube is connected with the water pump through a first pipeline; the second needle tube is communicated with the air compressor through a second pipeline; the liquid nitrogen container is communicated with the condenser; the spray head sprays liquid pesticide particles to the condenser intermittently; the condenser freezes the liquid pesticide particles into a solid state; and a scraping mechanism for scraping off the solid pesticide particles from the condenser is arranged on the unmanned helicopter. The liquid pesticide is divided into fine liquid pesticide particles and then sprayed to the condensation plate to be condensed into powder solid particles, then the condensed solid powder is sprayed downwards, the liquid pesticide is prevented from being cut by air, and the liquid pesticide can permeate to bottom blades.

    本发明公开了一种无人机自动喷药装置,包括无人直升机和喷药装置,喷药装置固定在无人直升机底部,第二针管连通第一针管,第二针管的底部连通有环形管,环形管的内径和第二针管内径相同,环形管内设有若干等间距的分割球,分割球通过连接线串联成闭合的环形,第一针管通过第一管道和水泵连接,第二针管通过第二管道和空压机连通,液氮罐和冷凝器连通,喷头间歇性向冷凝器喷出液态药物颗粒,冷凝器将液态药物颗粒冻结成固态,无人直升机上设有将固态药物颗粒从冷凝器刮下的刮除机构。将药液分割成细小的液态药物颗粒后喷向凝结板凝结成粉末固体颗粒,再将凝结成的固体粉末后向下喷洒,避免药液被空气切割,药液可以渗透到底部叶片上。
