Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicle pruning, in particular to a pruning unmanned aerial vehicle. Background Art

[0002] In recent years, multi-rotor drones have shown an explosive trend. The main stable structure is based on integrated circuit modules, sensors, high-precision measurement, automatic cruise technology and communication capabilities. At present, a large number of drones are used in plant protection environments, referred to as plant protection drones. DJI's drone market has been relatively complete. For example, DJI's T16 plant protection drone adopts a four-rotor structure design based on the function of spreading liquid medicine, which improves the efficiency of plant protection operations to a higher level. The wide-angle camera and imaging radar module contribute to its ability to move autonomously. In the direction of agricultural and forestry plant protection, drones can replace manual labor and greatly improve work efficiency. Similarly, the aerial operation range of quadcopters is constantly expanding, and drone systems with mechanical arms have also made great breakthroughs, such as the use of high-altitude cargo transmission and environmental cleaning in high-altitude environments. Therefore, today's development determines that quadcopters can complete their functionality according to the working mechanism. The pruning function in the plant protection link can also be applied to the design of quadcopters through design. Not only in plant protection, but also in the beautification of tree shapes in gardens, it is also within the reach of pruning drones.

[0003] However, the driving motors currently used on drones are mostly coil stator motors, which are large in overall size and weight. After assembly, the overall structure of the drone will be inconvenient and not light enough. In addition, the speed range and torque of the existing motor structure are limited, making it difficult to improve the working efficiency of the drone. Summary of the invention
