The invention discloses an agricultural unmanned aerial vehicle with an embedded screening gear plate. The agricultural unmanned aerial vehicle with the embedded screening gear plate comprises an unmanned aerial vehicle main body, wherein a plurality of sub propeller wings are arranged at the external side end of the unmanned aerial vehicle main body; a main propeller is mounted at the top of the unmanned aerial vehicle main body; the bottom of the main propeller is fixedly connected with a propeller motor; the screening gear plate also sleeves the main propeller; a plurality of screen holes are formed in the external side plate surface of the screening gear plate; a grain storing bin is arranged in the unmanned aerial vehicle main body at the upper end of the screening gear plate; a material outlet of the lower end of the grain storing bin is right against the screening gear plate; and the external bottom plate surface of the screening gear plate is led out from the unmanned aerial vehicle main body. Through the adoption of the mode, the screening gear plate can be driven by the main propeller to rotate so as to screen and spray seeds so that the seeds are uniformly and finely sprayed; therefore, the spraying range is enlarged and the spraying efficiency is increased.
