Agricultural multi-rotor UAV

Abstract

The invention provides a farm-oriented multi-rotor unmanned aerial vehicle which can be used for carrying out soil or water body sampling on non-flat surfaces with crops of farmlands and the like. The farm-oriented multi-rotor unmanned aerial vehicle comprises a rack, rotors, rotor motors, supporting legs, telescopic devices and sampling probes, wherein the telescopic device comprises a machine case, a wire coiling barrel, a wire coiling shaft, a first transmission gear, a clutch, a second transmission gear, a cable and a braking device; the rotor motors are double-axis motors; a lower rotating shaft is connected with an output gear and the output gear is connected with the first transmission gear; the first transmission gear is connected with the second transmission gear by the clutch; the second transmission gear is connected with the wire coiling shaft; the wire coiling shaft and the wire coiling barrel are sleeved peripherally; the cable is coiled on the wire coiling barrel; the free end of the cable is connected with the sampling probe; the braking device is mounted on the end face of the wire coiling barrel; the machine case is fixed on the rotor motors; the wire coiling shaft, the clutch and the braking device are fixed on the case body; the rotor motors, the clutch, the braking device and the sampling probes are electrically connected with an information processor.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an agricultural multi-rotor unmanned aerial vehicle used in the civilian field. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. It first appeared in the 1920s, when it was used as a target drone for training. is a term used by many countries to describe the latest generation of unmanned aircraft. Literally, the term can describe cruise missiles that have evolved from kites, radio-controlled aircraft, and V-1 missiles, but in military terms it is limited to reusable heavier-than-air vehicles. UAVs have a wide range of uses, low cost, good cost-effectiveness ratio; no risk of casualties; strong survivability, good maneuverability, and easy to use. They play an extremely important role in modern warfare and have broad prospects in the civilian field. From a technical point of view, it can...

Problems solved by technology

However, the inventors of this patent application have found through practice that when the drones in the prior art are used in agriculture, most of them can only fly over the crops for shooting and spraying operations, and lack the corresponding soil or soil for crop growth. A device for sampling the water body environment; in summary, there is an urgent need for a drone that can be used on uneven surfaces with crops such as farmland for soil or water sampling
