Folded-shape external-mixing type atomization sprayer based on special-shaped hole airflow assistance

Abstract

The invention aims to provide a folded-shape external-mixing type atomization sprayer based on special-shaped hole airflow assistance. The sprayer is formed by assembling a plurality of detachable type parts designed in a split manner. The sprayer comprises a water pipe, a connecting and sealing piece of the water pipe, a spliced hole connecting assembly, a pneumatic connector and a spray nozzle. In use, airflow sprayed out of an atomizing hole acts on fog drop groups at a certain angle, the fog drop groups are further crushed to achieve secondary atomization, the average diameter of liquid is reduced, the liquid distribution uniformity is improved, and therefore the atomizing quality is improved. Airflow sprayed out of a folded-shape hole acts on the fog drop groups at a certain angle, the airflow will narrow the effective covering area of the atomized liquid drops to achieve shape folding, and the spraying and applying accuracy and the pesticide utilizing rate of the sprayer are improved.

Description

technical field [0001] The invention relates to a sprayer applied to agricultural plant protection spraying, aiming at realizing the precise spraying of pesticides and improving the utilization rate of pesticide resources. Background technique [0002] Spraying with sprayer is an important part of agricultural plant protection technology. Improving the quality of atomization, narrowing the effective coverage area of ​​liquid medicine, improving the spraying accuracy of sprayer and the utilization rate of pesticides are of great significance to the development of sustainable agriculture in my country. The most important feature of the traditional plant protection sprayer is that by applying pressure to the liquid medicine, the liquid medicine is sprayed into the surrounding air at a relatively high speed, and the liquid medicine is atomized under the action of the surrounding air medium. At this time, the liquid after atomization The average droplet diameter is large, and the...

Problems solved by technology

The most important feature of the traditional plant protection sprayer is that by applying pressure to the liquid medicine, the liquid medicine is sprayed into the surrounding air at a relatively high speed, and the liquid medicine is atomized under the action of the surrounding air medium. At this time, the liquid after atomization The average droplet diameter is large, and the droplet distribution uniformity is poor, so the atomization quality is generally not high

Moreover, the traditional plant protection sprayers are almost all hollow cone spray nozzles, and the jet shape cross-section is approximately hollow ring. In the actual spraying process, in order to obtain sufficient liquid deposition, it can only be sprayed by multiple nozzles or a single nozzle. Spray multiple times to complete the liquid delivery

This traditional pesticide spraying method not only has low work efficiency, but also causes a lot of waste of pesticide resources, causing environmental pollution and food safety problems
