Target spraying machine capable of jointly adjusting areas of air inlets and air outlets and method

Abstract

The invention relates to the technical field of agricultural machinery, and discloses a target spraying machine capable of jointly adjusting areas of air inlets and air outlets and a method. The spraying machine comprises a two-dimensional laser radar, air conveying devices, a spraying device and a control device. The two-dimensional laser radar is used for collecting the target information of fruit trees. The air conveying devices are used for conveying air with the air speed and the air volume capable of being subjected to decoupling control. The spraying end of the spraying device is located on the air outlet sides of the air conveying devices. The input end of the control device is in communication connection with the two-dimensional laser radar, and the output end of the control device is in communication connection with air inlet area adjusting mechanisms and air outlet area adjusting mechanisms of the air conveying devices. When target air conveying pesticide spraying is carriedout on fruit trees in an orchard, air with the air speed and the air volume capable of being subjected to decoupling control can be conveyed, the air conveying pesticide spraying requirements for different types of fruit tree canopies are met, and a good pesticide spraying effect is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a target sprayer and a method for jointly adjusting the area of ​​an air inlet and an air outlet. Background technique [0002] As an efficient spraying technology in orchards, the wind-driven spraying technology uses high-speed airflow to further impact and atomize the spray droplets atomized by the nozzle into fine and uniform droplets to enhance the adhesion of the droplets. At the same time, the strong airflow will roll over The branches and leaves engulf the mist and penetrate into the inner chamber of the target, greatly increasing the penetrating ability of the mist. [0003] In recent years, with the development of sensor and automatic control technology, there has been a variable spraying technology for orchards on the target. Spraying on target variables in orchards includes the regulation of drug dosage and wind force. Among them, the technology of regu...

Problems solved by technology

[0006] The embodiment of the present invention provides a target sprayer and method with joint adjustment of the air inlet and outlet areas, which is used to solve the problem that the existing target sprayer has a gap between the wind speed and the air volume when spraying fruit trees by air. The "strong coupling" relationship between different types of fruit tree canopies is difficult to meet the needs of wind-driven spraying
