agricultural sprinkler

Abstract

The invention provides an agricultural sprayer including a rack and four rotors. The overall rack is in a cage-like shape; four rotors are articulated on the rack by two cylinders, two opposite rotors have the same direction of rotation, and two adjacent rotors have opposite rotational direction; a battery, a mini air compressor and a landing gear are fixedly arranged outside the rack; a container is arranged in the rack, the lower part of the container is provided with a discharge port, the discharge port is connected with a solenoid valve, the upper part of the container is provided with a seal cover; the battery provides power for rotor motors, a micro inflator and solenoid valve; and the outlet of the micro inflator is in communication with the cylinder bodies and the container. Compared with the prior art, the invention has the following characteristics: higher stability than other aircraft, strong wind resistance, flexible attitude, fast response, capability of hedgehopping, large carrying capacity, and splicing of discharge port at the bottom of the container with different nozzles to accommodate liquid or powder material spray according to different needs of people.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a small agricultural spraying unmanned aerial vehicle used in the agricultural field. Background technique [0002] Quadcopter is a kind of micro-aircraft, and it is also a kind of intelligent robot. It was originally made by aviation enthusiasts. Later, many automation manufacturers found that it can be used for multiple purposes and actively participated in the development. It uses four rotors as flight engines to fly in the air. It is small in size, light in weight, suitable for carrying and use, and has the ability of autonomous navigation and flight. [0003] People spray pesticides and fertilizers on crops manually, which not only makes laborers very tired but also wastes a lot of time, greatly reducing work efficiency. If the common implements for spraying pesticides and chemical fertilizers are changed to aircrafts, the laborers will not only reduce the burden on their bodie...

AI Technical Summary

Problems solved by technology

However, there are certain defects in the technical solution disclosed in this invention: the rotor is installed around the frame through the transverse connecting rod, and the rotor cannot be extended and lifted, so the flying attitude is poor, the response speed is slow, and the shipment is inconvenient; the medicine box is installed on the machine frame. The lower part of the frame makes the volume of the whole machine relatively large. A mechanically driven stirring device including a stirring cage, stirring shaft, coupling and stirring motor is installed in the medicine box. The power consumption is serious, and the spraying effect cannot be guaranteed.
