Multi-purpose multi-rotor foldable arm of agricultural unmanned aerial vehicle

Abstract

The invention relates to the technical field of agricultural unmanned aerial vehicles and discloses a multi-purpose multi-rotor foldable arm of an agricultural unmanned aerial vehicle. The multi-purpose multi-rotor foldable arm comprises an arm pipe front section (2), an arm pipe rear section (7), an arm folding fastener and an arm fixing base (8), wherein the arm fixing base (8) is installed at the tail of the arm pipe rear section (7). The multi-purpose multi-rotor foldable arm is characterized in that the arm further comprises a multifunction motor base (1) installed at the other end of the arm pipe front section (2); the arm folding fastener comprises a front folding fastener pipe clamp (3) and a rear folding fastener pipe clamp (6); the tops of the other ends of the front folding fastener pipe clamp (3) and the rear folding fastener pipe clamp (6) are each provided with a positioning plane (16); and one ends of the two positioning planes (16) are connected through a rotary fixing bolt (15), and the planes can be matched with each other. Through arrangement of the arm folding fastener, the height of the unmanned aerial vehicle is substantially reduced after the unmanned aerial vehicle is stored, the appearance is attractive, and assembling and disassembling are convenient.

Description

technical field [0001] The present invention relates to the technical field of agricultural unmanned aerial vehicles, and more specifically, relates to a foldable arm of a multi-purpose multi-rotor agricultural unmanned aerial vehicle. Background technique [0002] With the development of modern intelligent control, positioning, remote sensing, image processing and other technologies, small agricultural drones have the characteristics of accurate operation, high efficiency and environmental protection, intelligence, and simple operation, which can save farmers large machinery and a lot of labor costs, etc. Advantages, thus gradually accepted by the majority of farmers, has become a widely used agricultural machinery in modern agriculture. As one of the important components of plant protection drones, the arm of agricultural drones has a direct impact on the stability, safety, and operating efficiency of drones due to their structural rationality. [0003] At present, in the...

AI Technical Summary

Problems solved by technology

[0003] At present, in the absence of industry norms and standards in the production of drones, the following problems often occur in the arms: the deployment and closing of the aircraft are complicated, the volume is large after storage, and the space is large, and it is easy to be damaged during transportation; There is no ear buckle, so it is easy to cause the arm to loosen and rotate, which will cause the aircraft to shake during operation and the positioning of the arm is not accurate. Exposure to sunlight, serious aging, tube burst, etc.
