The invention discloses a plant protection unmanned aerial vehicle, and relates to the field of agricultural equipment. The plant protection unmanned aerial vehicle comprises a fuselage, a pesticide box, a motor and a nozzle, wherein the pesticide box is arranged on the fuselage and used for storing pesticide liquid; the motor is arranged on the fuselage, a cooling cavity is formed in the motor, and an inlet of the cooling cavity is communicated with the pesticide box; and the nozzle is arranged on the fuselage, communicates with an outlet of the cooling cavity and is used for spraying liquid medicine. According to the plant protection unmanned aerial vehicle, liquid medicine for spraying crops can be introduced into the cooling cavity in the motor to directly cool the motor before being sprayed out through the nozzle, so that the motor can be effectively ensured to have better heat dissipation and cooling effects while other cooling structures are prevented from being added and the cooling and heat dissipation cost is reduced; the safety and reliability of the motor can be provided, the service life of the motor is prolonged, and the operation efficiency and quality of the plant protection unmanned aerial vehicle are guaranteed.

    本发明公开了一种植保无人机,涉及农业设备领域;该植保无人机包括机身、药箱、电机和喷头;药箱设置于所述机身,用于储放药液;电机设置于所述机身,所述电机内开设有冷却腔室,所述冷却腔室的入口与所述药箱连通;喷头设置于所述机身,且与所述冷却腔室的出口连通,用于喷洒药液。该植保无人机用于喷洒农作物的药液在通过喷头喷出前,可通入电机内部的冷却腔室直接对电机进行降温,因而其能在避免附加其他冷却结构,降低冷却和散热成本的同时,有效地保证电机具有较优的散热和冷却效果,从而能提供电机的安全性和可靠性,延长电机的使用寿命,以保证植保无人机的作业效率和质量。
