The invention discloses a broadcaster for a plant protection unmanned aerial vehicle and the plant protection unmanned aerial vehicle, and the broadcaster comprises: a discharge pipe, one end of which is provided with a discharge port; and the material blocking structure is arranged at the discharge port and can prevent the materials in the discharge pipe from freely falling off from the discharge port under the action of gravity. According to the sowing device adopting the scheme, after driving discharging is stopped, the material blocking structure can prevent materials in the discharging pipe from continuously falling under the action of gravity, the purpose of accurate and quantitative discharging is achieved, and the problems of fertilizer damage and fertilizer waste caused by excessive discharging in the sowing process can be effectively solved.
本发明公开一种植保无人机用的撒播器及植保无人机,包括:出料管,其一端具有出料口;挡料结构,设置于所述出料口处,能够阻挡所述出料管中的物料在重力作用下从所述出料口自由掉落。使用本方案的撒播器,在停止驱动出料后,挡料结构可以阻挡出料管中的物料在重力作用下继续掉落,实现精准定量出料的目的,可有效减轻撒播过程中由于出料过量而导致肥害以及浪费肥料的问题。
