Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle fertilizing device. Background Art

[0002] In modern agricultural planting, in order to prevent and solve pests and supplement nutrients for crops, fertilization is an essential task. Some traditional fertilization methods are mostly completed by manual fertilization and mechanized fertilization. With the development of technology, the application of unmanned aerial vehicles in agricultural planting is also increasing, and the method of using unmanned aerial vehicles for auxiliary fertilization is becoming more and more common. In the prior art, some fertilizers are produced by the fusion of solid fertilizers and water, and most of the fertilization tanks of unmanned aerial vehicles are equipped with micro drive motors to stir the fertilizer liquid in the fertilization tank to prevent the insufficient dissolution of solid fertilizers from affecting the fertilization effect. This kind of drive motor is relatively energy-consuming;

[0003] An existing unmanned aerial vehicle fertilizing device with the publication number of CN213974473U can drive the fan to rotate by using the wind force generated when the body flies through the setting of the second rotating rod and the fan in cooperation with the second bevel gear. When the fan rotates, it will drive the first rotating rod to rotate through the second rotating rod. At this time, the first rotating rod can stir the fertilizer liquid in the storage tank through the cross plate. This can not only prevent the precipitation of the fertilizer solution in the storage tank but also play an energy-saving role. However, considering its overall structure, the spraying position coverage area of its structure is small, and the spraying range of a single flight is limited. Therefore, when carrying out spraying fertilization work for a large area, in order to achieve the requirement of uniform coverage spraying, the unmanned aerial vehicle needs to fly multiple times, with a high flight frequency, large consumption of the unmanned aerial vehicle, and often needs to be charged multiple times, and the overall spraying fertilization efficiency is not high.
