The invention discloses an agricultural unmanned aerial vehicle with convenient switching between solid and liquid. The bottom wall of the container in the frame is funnel-shaped, and a solid material discharge port with an external thread is arranged in the center of the bottom wall. A discharge port for liquid materials is set on the far bottom wall, and a cylindrical solenoid valve is screwed on the external thread of the discharge port for solid materials, and the solenoid valve is connected to the fertilizer hanging tube. The fertilizer motor is fixed at the lower end of the fertilizer hanging tube, and the fertilizer Spreading windows are evenly set on the circumferential wall of the hanging tube, and the spreading blades are fixed on the motor shaft of the fertilizer motor, and the spreading blades are located in the fertilizer hanging tube corresponding to the spreading windows; the liquid material outlet is connected to the micro pump. The water inlet and the water outlet of the miniature water pump are connected with two liquid material spray rods provided with nozzles. Compared with the prior art, the present invention does not need to replace the spray head when performing different tasks, which is very convenient.
Description
technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a small unmanned aerial vehicle used in the field of agriculture, which can conveniently realize solid-liquid switching. Background technique [0002] The inventor disclosed an agricultural sprinkler through the publication number CN104908937B earlier, and proposed that according to different needs of people, different nozzles can be connected to the discharge port at the bottom of the container to adapt to the technical solution of spraying liquid or powder materials. However, this solution needs to replace the nozzle in advance every time a different task is performed, which is cumbersome for the user. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an agricultural unmanned aerial vehicle that can conveniently realize solid-liquid switching. [0004] In order to solve the above-mentioned technic...
