Description

Technical Field

[0001] The invention relates to the technical field of forestry spraying equipment, in particular to a drug spraying device and method for preventing and controlling forestry pests and diseases. Background Art

[0002] As the name suggests, pesticide spraying equipment for forest pest control is specially designed to spray pesticides or biological control agents on trees accurately and efficiently, aiming to prevent or control various pests and diseases, thereby protecting the healthy growth of forest resources. This type of equipment plays a vital role in forestry management and is directly related to the health of trees and the balance of the entire ecosystem.

[0003] At present, with the advancement of science and technology, drug spraying equipment is also constantly innovating. Among them, one of the more advanced equipment is the use of drone technology for drug spraying. Drones have been widely used in forestry pest control due to their advantages such as strong flexibility, wide operating range, and easy operation. However, when faced with a complex environment with dense trees and lush branches and leaves, drone spraying operations face challenges. Because the trees are lush and cover the area below, it is difficult for drones to evenly spray drugs on the branches and trunks below the trees, which not only affects the prevention and control effect, but may also lead to drug waste and environmental pollution. Therefore, although drone spraying has many advantages, its limitations are also obvious in specific situations.

[0004] Another common type of drug spraying equipment is to use a fog cannon. The fog cannon uses high pressure to mix water and drugs to form mist particles, and uses wind power to spray the droplets over a long distance, covering a relatively large area. However, existing fog cannons still have shortcomings in terms of drug spraying distance and penetration. Especially when facing tall and dense trees, the spraying effect of fog cannons is often unsatisfactory, and it is difficult to ensure that the drugs can penetrate into areas with dense branches and leaves to achieve the purpose of comprehensive prevention and control. In addition, the use of fog cannons may also be restricted by natural conditions such as terrain and wind direction, further affecting their prevention and control effects. Summary of the invention
