Description

Technical Field

[0001] This application relates to the technical field of drones, and in particular to a spraying device for an agricultural drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices[1]. UAVs are actually a general term for unmanned aerial vehicles, which can be divided into several categories from a technical point of view: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paragliders.

[0003] A search revealed Chinese Patent Publication No. CN221044110U, which discloses a pesticide spraying device for an agricultural drone. The device includes a pesticide storage chamber, shock-absorbing feet, a stirring component, an adjusting component, and a hook. The bottom of the pesticide storage chamber has four shock-absorbing feet arranged in a circular array. A stirring component is fixedly connected to the storage chamber, and four adjusting components are arranged in a circular array on the outer wall of the storage chamber. This invention allows the pesticide spraying device for agricultural drones to be used independently. The adjusting and hook components enable convenient installation of the storage chamber under the drone for use under different conditions. The stirring component inside the storage chamber prevents pesticide sedimentation during drone flight. The shock-absorbing feet provide cushioning during takeoff and landing, improving the protection of both the drone and the spraying device.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: the prior art lacks a filtration mechanism, which causes impurities and undissolved pesticide particles in the water to clog the spraying device. In order to solve the deficiency of the lack of a filtration mechanism in the prior art, this application rotatably connects the two ends of the first connecting rod to the second gear and the fifth gear respectively, so that when the second gear rotates, the first connecting rod scrapes the filter screen with a cleaning brush, thereby achieving a cleaning effect.
