Description

Unmanned aerial vehicle spraying device Technical Field The utility model relates to the field of aerial work robots, in particular to an unmanned aerial vehicle spraying device. Background With the development of building technology, the height of the existing building is increased, but the spraying is inconvenient for high-rise buildings needing spraying. Traditional spraying mode sprays through the manual work, but sprays through artifical high-rise building not only with high costs, inefficiency, and the workman is big in the action range of spraying in-process moreover, has the risk of falling. For improving efficiency, reduce cost and security risk, people spray high-rise building through the flying equipment, but the feed bin capacity that current flying equipment carried is limited, leads to the flying equipment to need the material loading many times in the spraying in-process, and complex operation has still reduced spraying efficiency. The spray boom of the existing unmanned aerial vehicle spraying device is fixed, can only spray forwards, can only spray the front wall when spraying paint, is difficult to cover complex structures such as corners and windowsill, and is easy to form a working blind area when only supporting unidirectional spraying. In the rust removal and corrosion prevention device of the unmanned aerial vehicle, relevant technicians concentrate all parts of the steering mechanism at the spray head, so that stress is concentrated at the end part of the spray boom, which is close to the spray head, and the spray boom is easy to bend and deform, so that the spraying angle can be changed gradually, the spraying effect is difficult to ensure, and the improvement is required.
