An orchard target sprayer and method for jointly controlling the air inlet and outlet areas

Abstract

The invention relates to the technical field of agricultural machinery, and discloses an orchard target sprayer and method for jointly regulating the air inlet and outlet areas, the sprayer includes: an ultrasonic sensing array, which is used to collect target information of fruit trees; The air supply 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 supply device; the control device, the input end of the control device is connected to the ultrasonic sensor array, and the output end The air inlet area adjustment mechanism and the air outlet area adjustment mechanism of the air delivery device are respectively connected by communication; when the present invention sprays the target air to the fruit trees in the orchard, it can realize the decoupling controllable wind delivery of wind speed and air volume, satisfying the The wind-driven spraying requirements for 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 an orchard targeting sprayer and method for jointly regulating the air inlet and air outlet areas. 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 reg...

Problems solved by technology

[0006] The embodiment of the present invention provides an orchard target sprayer and method that jointly regulates the air inlet and outlet areas, which is used to solve the problem of wind speed and air volume in the air delivery of the existing target sprayer when spraying fruit trees by air. The "strong coupling" relationship between them makes it difficult to meet the needs of wind-driven spraying for different types of fruit tree canopies
