Description

Unmanned aerial vehicle horn angle adjustment subassembly, horn and unmanned aerial vehicle Technical Field Relates to the technical field of unmanned aerial vehicles. Background With the development of modern society, people pay more attention to the quality and safety of agricultural products. Under such a background, agricultural plant protection unmanned aerial vehicles are becoming one of the indispensable tools in modern agriculture. First, compare traditional manual work and spray, agricultural plant protection unmanned aerial vehicle can guarantee the accurate positioning and the coverage of operation, improves the operating efficiency. And secondly, the agricultural plant protection unmanned plane can reduce the influence on the environment and ecology and protect the sustainable development of the ecological environment. In the traditional agricultural production, a large amount of chemical fertilizers and pesticides are used, so that the environment is polluted greatly and resources are wasted. And agricultural plant protection unmanned aerial vehicle can be according to actual need accurate spraying pesticide and fertilizer, avoids excessive use, reduces the influence to ecological environment. Furthermore, the agricultural plant protection unmanned aerial vehicle can also promote the sustainability of agricultural production and accelerate the agricultural modernization process. With the development of urban and industrialized production, rural population is generally lost, and agricultural production is gradually atrophic. But the application of the agricultural plant protection unmanned plane can enlarge the production space of farmers, improve the yield and benefit, and simultaneously reduce the labor cost and the investment of pesticide and fertilizer, so that the agricultural production is more convenient, economical and efficient. In the development process of the existing unmanned aerial vehicle, the agricultural plant protection unmanned aerial vehicle can be used for spraying liquid pesticides or nutrient solutions such as pesticides, bactericides, herbicides, ripening defoliants, sugar enhancers, foliar fertilizers and the like, sowing solid seeds and mapping farmland. The application of the agricultural plant protection unmanned aerial vehicle has very important effects on preventing and controlling plant diseases and insect pests and improving the crop yield. However, when other spraying equipment such as present traditional agricultural plant protection unmanned aerial vehicle sprays pesticides to plants such as fruit trees, cash crops, because the growth direction of fruit tree branch is the slant and upwards diverges and grows, outside leaf can produce the shielding to inside branch, leaf. When agricultural plant protection unmanned aerial vehicle from top to bottom sprays to trees, the pesticide that sprays hardly pierces through the shielding of leaf, sprays evenly to the leaf of whole trees. Therefore, the technical problems of uneven spraying and incomplete spraying exist for the traditional agricultural plant protection unmanned aerial vehicle. In 2021, 3 months 23 days published patent document of application number 202021255569.X, provide an unmanned aerial vehicle of adjustable support arm angle, through angle adjustment mechanism, realized the regulation of unmanned aerial vehicle horn angle for the pesticide that unmanned aerial vehicle sprayed has certain angle with vertical direction, and because the downforce of rotor, further provides the mobility for the pesticide that sprays under this angle, improves penetrability. However, according to the disclosure of the text and the drawings, the angle adjustment is realized by a detachable angle adjustment component, when the horizontal support arm is needed, the component is connected with the adjustment mechanism, the support arm is connected with the component, namely, the length of the adjustment mechanism is prolonged, the horizontal posture of the support arm is fixed, and when the angle of the support arm is needed to be adjusted, the component is detached, the support arm is directly connected with the adjustment mechanism, and the angle of the support arm is naturally raised because the length of the adjustment mechanism is reduced. The implementation of this structure then results in more cumbersome operating steps to be taken when changing angles, and since the arm angle needs to be adjusted only in specific months each year, it is necessary to ensure that the disassembled angle adjustment assembly is kept intact, must not be lost, and increases the effort of the user, making this adjustment structure inconvenient to use. Disclosure of Invention In order to solve the technical problems that the prior unmanned aerial vehicle support arm angle adjusting mechanism needs to adopt more complicated operation steps when changing angles and needs to ensure that the detached angle adjusting assembly is well preserved and
