Orchard targeting sprayer and method for combined regulation and control of fan and air outlet area

Abstract

The invention relates to the technical field of agricultural machinery, and discloses an orchard targeting sprayer and method for combined regulation and control of a fan and an air outlet area; the sprayer comprises an ultrasonic sensing array, an air supply device, a spraying device and a control device, wherein the ultrasonic sensing array is used for collecting the target information of a fruit tree; the air supply device is used for conveying air of which the air speed and the air volume can be decoupled and controlled; the spraying end of the spraying device is located on the air outletside of the air supply device; and the input end of the control device is in communication connection with the ultrasonic sensing array, and the output end of the control device is in communication connection with a fan of the air supply device and an air outlet area adjusting mechanism. When targeted air-assisted pesticide spraying is carried out on fruit trees, air with the fruit tree conveyingair speed and air volume capable of being decoupled and controlled can be achieved, the air-assisted pesticide spraying requirements for different types of fruit tree canopies are met, and the relatively good pesticide spraying effect is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an orchard targeting sprayer and a method for jointly regulating the blower fan and the air outlet area. Background technique [0002] Effective control of orchard pests and diseases can save huge economic losses. The existing pest control methods mainly rely on chemical pesticides. According to survey statistics, the number of times fruit trees need to spray pesticides is 8-15 times a year. With the increase of population aging, heavy spraying operations have become the main factors affecting orchard management. In order to overcome this problem, some robots for orchard operations have been developed. However, most of these robots are aimed at fruit picking and harvesting, and there are relatively few robots for orchard spraying. [0003] As an efficient automatic spraying technology in orchards, the air-driven spraying technology uses high-speed airflow to furth...

AI Technical Summary

Problems solved by technology

[0007] The embodiment of the present invention provides an orchard target sprayer and method that jointly regulates the fan and the air outlet area, which is used to solve the problem that the existing target sprayer cannot realize the wind speed of the conveying wind force when spraying fruit trees by air. It is difficult to meet the needs of wind-driven spraying for different types of fruit tree canopies due to the independent adjustment of air volume
