The chain line in fig. 2, 3, 18 of the present invention is used to embody the axial direction in the assembly.

The aircraft 800 (e.g., unmanned aerial vehicle) often needs to carry different working devices for agricultural work, for example, needs to carry a spraying device for spraying medicine or moisture, so as to meet the growth requirements of agricultural and forestry crops. In the related art, the whole spraying device is relatively fixed relative to the aircraft body 81 of the aircraft 800, the angle of the spraying device cannot be adjusted, the spraying device cannot adapt to the flight postures of different aircraft 800, the optimal spraying effect cannot be achieved, and the application range is limited; moreover, the spraying device is troublesome to disassemble and inconvenient to maintain.

In the field of the aircraft 800, other operation equipment needs to be carried to meet the working task requirements of the aircraft 800 in the fields of plant protection, aerial photography, environmental management, surveying and mapping, power inspection, forest fire prevention and the like; in other unmanned devices, different working devices are required to be carried to perform work tasks, for example, for an agricultural unmanned vehicle, a spraying device can be carried on a vehicle body; in the unmanned ship, a bait casting device or the like may be mounted on the hull. In the related art, when the working device is mounted on the apparatus main body, the angle of the working device is generally inconvenient to adjust, and the working device is inconvenient to detach, maintain, and replace.

In view of this, the present invention provides a mounting assembly, which can solve the above-mentioned problems, and can realize relative rotation between two members and quick detachment between two members, and through the cooperation of the male limiting part 41 and the female limiting part 42, the reliable connection between two members can be maintained without external force.

The installation assembly can be applied to the operation device, and when the operation device adopting the installation assembly is applied to relevant equipment, the angle of the operation device relative to the equipment main body is convenient to adjust, and the operation device is easy to detach from the equipment main body.

When this installation component is applied to the operation device, the operation device can be but not limited to sprinkler, seeder, sound information acquisition device, air current information acquisition device, image acquisition device, the device of feeding etc..

When this installation component was applied to sprinkler, be convenient for adjust the angle of the relative mount pad of shower nozzle 202, relative equipment main body, application scope is wider to sprinkler easily dismantles, the maintenance of being convenient for.

Through the angle modulation to sprinkler's shower nozzle 202, can effectively adapt to plant protection unmanned aerial vehicle's different flight gesture (fly forward, fly backward), improve sprinkler's the precision of spraying and spray width, promote and spray the effect.

The flight attitude of the aircraft 800 has an effect on the spraying effect of the spraying device: when aircraft 800 is rotor craft 800, when the rotor orientation was relatively unanimous with shower nozzle 202 orientation, shower nozzle 202 spun liquid can be followed the air current of rotor below and spouted to the crop, and when the rotor orientation was carried on the back with shower nozzle 202 orientation mutually, shower nozzle 202's spraying route then can be hindered by the air current of rotor below, leads to the liquid that sprinkler sprayed to can't spray to the crop along predetermineeing the route. Therefore, when the angle of the spraying device of the aircraft 800 can be adjusted relative to the rotor wing mechanism, the spraying device can effectively adapt to different flight attitudes of the aircraft 800, and the spraying effect is ensured.

Of course, the mounting assembly may be applied to other mechanical devices besides a working device such as a sprinkler.
