[0002] With the development of construction technology, the height of existing buildings has also increased, but for high-rise buildings that need to be sprayed, spraying is extremely inconvenient. The traditional spraying method is to spray manually, but spraying high-rise buildings manually is not only costly and inefficient, but also workers have large movements during the spraying process, and there is a risk of falling. In order to improve efficiency, reduce costs and safety risks, people use flying equipment to spray high-rise buildings, but the existing flying equipment has a limited silo capacity, which results in the need for multiple loading of materials during the spraying process. The operation is cumbersome and reduces the spraying efficiency.

[0003] In the prior art, a patent document with publication number CN209393388U discloses a high-altitude spraying equipment, including a drone and an automatic spraying assembly; the drone is connected to the control equipment on the ground with electrical signals, and the drone is used to locate near a target object in the sky; the automatic spraying assembly is connected to the drone, and the automatic spraying assembly is used to automatically spray the spraying liquid onto the target object; the automatic spraying assembly includes a liquid tank, a signal control unit, and a remote controller. However, the liquid tank capacity of the spraying equipment is limited, and the spraying liquid needs to be replenished multiple times during the spraying process, which is not only cumbersome to operate, but also reduces the spraying efficiency of the flying equipment.

[0004] Therefore, a spraying equipment suitable for high floors is urgently needed to solve the above problems. Summary of the invention

[0005] In view of the problems in the prior art, the utility model proposes a spraying equipment suitable for high floors.
