An adaptive canopy opening airflow assisted spraying device and method

Abstract

The invention relates to an adaptive canopy opening airflow auxiliary spraying device and method, comprising a spray bar frame, a spraying module, an air supply module and a canopy opening module. The boom frame is used to support and fix other modules, and is connected with the sprayer; the spray module is used to complete the pressure atomization of the liquid medicine, and release the liquid spray droplets to the canopy at a certain angle; The droplets are transported into the canopy; the canopy opening module is used to push the dense branches and leaves on the upper part of the plant to provide a downward migration channel for the droplets; when spraying, the flexible cover is in front of the spray area, and the upper canopy branches are opened Canopy space, while assisting airflow to force droplets into the canopy and improve the deposition and distribution of droplets in the middle and lower parts of the plant. It has the characteristics of simple structure, high reliability, small mechanical damage to plants, and good spraying effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection machinery, and relates to a self-adaptive canopy opening airflow assisted spraying device and method, which realizes self-adaptive opening of the upper canopy space for the spraying object, and assists airflow to force the droplet to deposit inside the canopy, thereby improving spray application. The overall deposition distribution of drug objects in the canopy. Background technique [0002] As an efficient ground application technology, air-assisted spraying is widely used in various application scenarios. When the upper canopy of the application object is seriously shaded and the auxiliary airflow cannot effectively open the canopy space, the spray droplets of the drug solution are often concentrated and deposited on the upper part of the canopy, resulting in uneven deposition of the whole, too little deposition of the drug solution in the middle and lower parts, and poor a...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the above technologies, the present invention provides an adaptive canopy opening airflow assisted spraying device and method, which solves the problem of insufficient deposition of liquid droplets in the middle and lower parts caused by the shading of branches and leaves in the upper canopy during the spraying process. , has the characteristics of simple structure, low maintenance and installation costs, small demand for auxiliary airflow wind speed, reduces power consumption caused by pure airflow auxiliary spraying, better adaptability to plant canopy and less mechanical damage to branches and leaves
