Description

Technical Field

[0001] The utility model relates to the technical field of atomizing nozzles, and more specifically to an automatic dredging and diffusing device for atomizing nozzles. Background Art

[0002] A pneumatic sprayer is a spraying machine that utilizes the high-speed airflow generated by a fan to impact the spray, and the droplets are ejected with the airflow. Usually, in order to make the droplet spray distance long and the droplet particles small, a two-fluid nozzle is usually equipped. The two-fluid nozzle is provided with an airflow channel and a liquid channel. The liquid and gas collide at the nozzle outlet to produce droplets, and the high-speed airflow sprays the droplets. However, the droplet particles produced by such a direct collision are relatively large, and direct airflow can easily cause crop damage and fail to meet the atomization requirements. At the same time, the existing pneumatic atomizing nozzles are also prone to blockage and concentrated droplet spraying, which leads to technical problems such as easy damage to crops caused by drugs. Therefore, they need to be replaced and repaired frequently. For this reason, this scheme proposes an automatic dredging and dispersion device for atomizing nozzles. Utility Model Content

After the medicine in the infusion tube is sprayed out, it is atomized into small particles under the action of high-speed wind and hits the diverging piece. The droplets are further crushed and diverged toward the edge of the diverging piece with the high-speed wind to form divergent micro-mist particles.
