Compared with the prior art, this an agricultural unmanned aerial vehicle for water-saving irrigation passes through the water capacity that water storage mechanism conveniently adjusted in the water tank 2, guarantee the work efficiency and the duration of equipment, moreover, irrigation mechanism is adjustable spray tube 8 direction after the operation is accomplished, make guard plate 10 be located spray tube 8's below, rotor plate 12 rotates to the coplanar with guard plate 10 simultaneously, utilize rotor plate 12 and guard plate 10 to contact ground when equipment lands, prevent that shower nozzle 9 on the spray tube 8 from receiving the extrusion and damaging, guarantee equipment safety landing, the practicality of equipment has been improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
