Description

Unmanned aerial vehicle medicine application shower nozzle rotation locking component, shower nozzle, horn and unmanned aerial vehicle Technical Field Relates to the technical field of locking, in particular to an unmanned aerial vehicle with a rotatable locked pesticide spray head. 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. 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, the structural design of the traditional agricultural plant protection unmanned aerial vehicle is not reasonable enough, for example, the structural layout of the existing pumping device is not reasonable enough, the work is not stable enough, the spray droplets are not uniform enough, the size is large, and the weight is heavy. And due to the limitation of the arrangement of the spray boom relative to the machine body, the plant protection unmanned aerial vehicle has the problem of leaking spray phenomenon when spraying the medicine. Therefore, the related structure of the agricultural plant protection unmanned aerial vehicle needs to be optimized so as to improve the working efficiency. In the patent document of patent number ZL202111350976.8 published on month 1 of 2022, a pesticide application device carried by an unmanned aerial vehicle is provided, and through the mutual cooperation of a water tank, an impeller pump, a spray head and a fluid pipeline, unmanned aerial vehicle plant protection equipment has larger spraying flow, reduces the load of the unmanned aerial vehicle, and improves the spraying efficiency. However, this structure has a limitation in that the spray head is fixed, so that it can only have a fixed spray angle and spray range, and thus cannot provide a more widely applicable unmanned pesticide application vehicle. Disclosure of Invention In order to solve the technical problems that the existing unmanned aerial vehicle for applying medicine has only fixed spraying angle and spraying range due to the fixed structure of a spray head in the prior art, and the unmanned aerial vehicle for applying medicine with wider applicability cannot be provided, the technical scheme provided by the invention is as follows: unmanned aerial vehicle spray head rotation locking subassembly that applies medicine, the subassembly includes: the device comprises a fixed seat for connecting an unmanned aerial vehicle arm, a movable seat for connecting an unmanned aerial vehicle pesticide spraying nozzle and a sleeve; The fixed seat and the movable seat are hollow and are used for passing through a water pipe and a circuit; a connecting end is arranged at one end, far away from the horn, of the fixing seat, and a limiting protrusion is arranged on the side wall of the end part of the connecting end; The inner wall of the sleeve is provided with a positioning bulge; A positioning groove is formed in one end, close to the horn, of the movable seat; the limiting protrusion and the positioning protrusion mutually fix the position relationship between the s
