The invention discloses an agricultural unmanned aerial vehicle. The agricultural unmanned aerial vehicle comprises a vehicle body; the vehicle arms extend out of the vehicle body; the power motor is arranged at the end part of the machine arm, an air flow channel which is through up and down is arranged in the power motor, a top cover is further mounted on the top side of the power motor, an air inlet hole is formed in the top cover, and when the agricultural unmanned aerial vehicle flies forwards, air flow can be injected into the air flow channel through the air inlet hole so as to carry away heat in the power motor; and the propeller is connected with the power motor. In the forward flying process of the agricultural unmanned aerial vehicle, forward flying countercurrent can be injected into the airflow channel of the power motor through the air inlet holes and is discharged downwards through the airflow channel, the purpose of promoting rapid dissipation of heat in the power motor is achieved, and the problem that heat dissipation of the power motor is difficult in the forward flying process is solved; and a series of problems that the performance of the power motor is influenced, the electric conversion efficiency is reduced, the service life of the power motor is shortened and the like caused by poor heat dissipation of the motor are effectively solved.
