Laser radar-based orchard target air-assisted sprayer and spraying method thereof

Abstract

The invention relates to the technical field of agricultural machinery, and discloses a laser radar-based orchard target air-assisted sprayer and a spraying method thereof; the sprayer comprises a two-dimensional laser radar, a speed detection device, an air supply device, a spraying device and a control device, wherein the two-dimensional laser radar is used for collecting target information of fruit trees; the speed detection device is used for acquiring running speed information of the sprayer; the air supply device is used for conveying air of which the air speed and the air volume can bedecoupled and controlled; the spraying end of the spraying device is located on the air outlet side of the air supply device; and the control device is connected with the two-dimensional laser radar,the speed detection device, the air supply device and the spraying device separately. According to the laser radar-based orchard target air-assisted sprayer, when targeted pesticide spraying is conducted in an orchard, the pesticide spraying amount and wind power sprayed to fruit tree canopies are cooperatively regulated and controlled according to needs, the problem that strong coupling exists between the wind speed and the wind quantity when targeted spraying is conducted on fruit trees traditionally is solved, 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 a lidar-based orchard air-to-target sprayer and a spraying method thereof. Background technique [0002] In recent years, with the increase of population aging, heavy spraying has become the main factor affecting orchard management. At present, 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 used for orchard spraying. Most of the orchard spraying robots are only suitable for the on-demand regulation of the spraying amount, and there are few orchard spraying robots that support the on-demand regulation of the amount and wind. In the process of spraying fruit trees, if the wind force is too small, the deposition in the canopy chamber of the fruit tree will be insufficient, and if the wind force is too strong, the liq...

Problems solved by technology

[0006] The embodiment of the present invention provides a lidar-based orchard air-driven sprayer for target-targeting, which is used to solve the problem that the existing target-targeting sprayer is difficult to coordinate and realize the on-demand dose and wind force when spraying the fruit trees in the orchard. Control and overcome the "strong coupling" relationship between wind speed and air volume during spraying
