The invention discloses a self-pressurization type spraying device for a plant protection unmanned aerial vehicle. The device comprises an unmanned aerial vehicle body and a mounting box arranged below the unmanned aerial vehicle body, a water tank is connected into the mounting box through a reinforcing rod, a stirring mechanism is arranged on the mounting box, and a pressurization mechanism connected with the stirring mechanism is arranged in the water tank; a hollow rod communicating with the pressurization mechanism is rotatably arranged at the bottom of the pressurization mechanism, the end, penetrating to the bottom of the mounting box, of the hollow rod is connected with an annular spraying pipe communicating with the hollow rod, and a driving mechanism for driving the hollow rod torotate is arranged in the mounting box; through the arrangement of the stirring mechanism and the pressurization mechanism, the stirring mechanism enables liquid medicine and water to be sufficientlymixed, the pressurization mechanism is used for pressurizing, so that the liquid medicine is sprayed out from a lower nozzle of the annular spraying pipe, the influence of wind power on the liquid medicine in the spraying process is reduced, the spraying effect is improved, a pressurizing element does not need to be additionally arranged, and the production cost is reduced; and by arranging the driving mechanism, the annular spraying pipe continuously rotates in one direction, and therefore the spraying range of the spraying device is enlarged.

    本发明公开了一种植保无人机用自加压式喷洒装置,无人机本体以及设于无人机下方的安装箱,所述安装箱内通过加固杆连接有水箱,且安装箱上设有搅拌机构,所述水箱内设有与搅拌机构相连的加压机构,所述加压机构的底部转动设有与其连通的中空杆,所述中空杆穿设至安装箱底部的一端连接有与其相通环形喷管,所述安装箱内设有驱动中空杆转动的驱动机构,通过设置搅拌机构和加压机构,搅拌机构使药液与水充分混合,并通过加压机构进行加压,从而使药水从环形喷管下喷嘴喷出,减少了喷洒过程中药液受风力的影响,提高了喷洒效果,无需另外设置加压元件,减少了生产成本;通过设置驱动机构,使环形喷管持续单向转动,从而增加了喷洒装置的喷洒范围。
