The invention provides a novel mist sprayer applied to a plant protection unmanned aerial vehicle in the technical field of unmanned aerial vehicles, which comprises an unmanned aerial vehicle, a mist sprayer and equipment related to the mist sprayer, such as a water storage tank and a medicine tank. Wherein the unmanned aerial vehicle is a main working device, a rack is arranged below the unmanned aerial vehicle, a water storage tank, a pesticide tank and a mist sprayer are arranged on the rack, and the mist sprayer is connected to the rack through a buffer device. According to the mist sprayer, by arranging a large-caliber and small-caliber switching structure, the working state of pesticide at an outlet of the mist sprayer is adjusted, and when the mist sprayer is switched into a large-caliber mist sprayer, the action area of pesticide spraying is wide, the distance is short, and the momentum of the pesticide at the outlet is small; when the mist sprayer is switched into a small-caliber mist sprayer, the action area of spraying the pesticide is small, the distance is long, and the momentum of the pesticide at an outlet is large; a plurality of outlets are added under the action of the small caliber, and the size of the combined total outlet is basically consistent with the size of the outlet of a large-caliber mist sprayer, namely, when the mist sprayer is used for spraying distant crops, the efficiency can be improved due to the large action area. When the mist sprayer is switched into a large-caliber structure, due to the fact that the momentum of pesticide at an outlet is small, the backflow phenomenon may be caused, and the service life of the mist sprayer is affected, the small-caliber structure has the backflow preventing effect under the non-working effect, the backflow pesticide is stored in the small-caliber structure, and when the small-caliber structure needs to spray out, the pesticide can be sprayed out through the small-caliber structure. The medicine in the small-caliber structure is sprayed firstly, and waste of the medicine is prevented.
本发明在无人机技术领域中提出一种应用于植保无人机的新型弥雾机,其包括其包括无人机、弥雾机以及弥雾机相关的设备,例如储水罐和药物罐。其中无人机为主要作業装置,无人机下方设有机架,机架上设置有储水罐和药物罐以及弥雾机,弥雾机通过缓冲装置连接在机架上。本发明通过设有切换大小口径结构,对弥雾机出口的药物工作状态进行调节,当切换成大口径的弥雾机,喷洒药物的作用面积较广,距离较近,出口药物的动量较小;当切换成小口径的弥雾机,喷洒药物的作用面积较小,距离较远,出口药物的动量较大;本发明在小口径的作用下增加了多个出口,其组合成的总出口的大小与大口径弥雾机的出口大小基本一致,即对远处的农作物进行喷洒时,也会因作用面积大而提高效率。本发明当切换成大口径结构时,由于出口处的药物动量较小,可能会导致回流的现象影响弥雾机的工作寿命,本发明的小口径结构在不工作的作用下还有防止回流的效果,将回流的药物储存在小口径结构内,当需要小口径结构喷射出时,首先喷射处小口径结构内的药物,防止浪费药物。
