According to the request of adopting advanced technology, the main designing has such contents as below:⑴ Designing the two-fluid nozzle that is based on the theory of air-atomize spraying.⑵ Designing and choosing the type of the axial fan that is used to supply assisted airflow to waft droplets that comes from nozzle.⑶ Designing the swaying outfit that can rotate the spray assembly at a speed and inside a angle in order to satisfy the spray request of different crops, different planting states and improve the uniformity of distribution, the deposition of droplet. Here, we select TYV type reduction gear motor to adjust the swaying speed and use course switch to adjust the swaying angle.⑷ Designing the lift outfit that can adjust the height of the spray assembly to satisfy the request of the crops of different tallness, different spraying range. Here, we select cylinder as the main component that can be used as kickstand and controlled easily.⑸ Designing the switch of the power supply that is put out of the greenhouse in order to prevent worker from poisoning. After the mist sprayer being made, the experiment is made to test the function of the greenhouse mist sprayer fully.
