Abstract

An agricultural unmanned aerial vehicle (10) comprises a base frame (11), a plurality of nozzle assemblies (13), a plurality of water pumps (14), a water tank (15) and a controller (16). The base frame comprises a central body (111) and a vehicle arm (112). The plurality of nozzle assemblies are distributed on two sides of the base frame in a roll axial direction of the agricultural unmanned aerial vehicle below the vehicle arm, and the nozzle assembly comprises a plurality of nozzles (131). The plurality of water pumps are in communication with the plurality of nozzle assemblies respectivelyand configured to transport a liquid flow to the nozzles and spray the same therethrough. The plurality of water pumps are in communication with the water tank. The controller is electrically connected to the water pump and can selectively control the plurality of water pumps to perform spraying by means of the nozzle assembly in communication with the selected water pump. The vehicle arm comprises a left arm (112a) and a right arm (112b) in the roll axial direction of the agricultural unmanned aerial vehicle, each of the left arm and the right arm corresponds to at least one nozzle assembly respectively, and each nozzle assembly share one water pump. The agricultural unmanned aerial vehicle can realize accurate controlled spraying.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an agricultural unmanned aerial vehicle. Background technique [0002] At present, the multi-rotor agricultural unmanned aerial vehicles on the market generally use a single water pump to connect to the pipeline, and the pipeline is connected to the nozzle to form a spraying liquid path. This method only simply realizes the switching on and off of the liquid circuit system, and cannot realize the precise control and spraying of agricultural unmanned aerial vehicles. Contents of the invention [0003] The object of the present invention is to provide an agricultural unmanned aerial vehicle that can realize precise control of spraying. [0004] An agricultural unmanned aerial vehicle, comprising: [0005] a frame comprising a central body and a plurality of arms extending from the central body; [0006] A plurality of nozzle groups are distributed on both sides of the frame in the...
