Target sprayer and method for joint adjustment of air inlet and outlet areas

Abstract

The invention relates to the technical field of agricultural machinery, and discloses a target sprayer and a method for jointly adjusting the area of ​​the air inlet and outlet. The sprayer includes: a two-dimensional laser radar, which is used to collect target information of fruit trees; The delivery device is used to deliver the wind whose wind speed and air volume can be decoupled and controlled; the spray device, the spray end of the spray device is located on the air outlet side of the air delivery device; the control device, the input end of the control device is connected to the two-dimensional laser radar, and the output ends are respectively The air inlet area adjustment mechanism and the air outlet area adjustment mechanism of the air supply device are connected by communication; when the present invention is spraying the fruit trees in the orchard with the target wind, it can realize the decoupling controllable wind speed and air volume, which meets the requirements for The wind-driven spraying requirements of different types of fruit tree canopies have achieved better drug spraying effects.

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
