Technical Field

[0001] The invention relates to the technical field of agriculture, and in particular to automatic pesticide application equipment for preventing and controlling agricultural pests and diseases. Background Art

[0002] The prevention and control of pests and diseases is the most time-consuming and important task in orchard management. Different pesticides need to be sprayed at different stages of fruit trees to prevent and kill insects.

[0003] Different fruit trees have different trunk and crown specifications. When the crown needs to be fully sprayed, the spraying equipment rotates around the fruit tree to spray. The equipment as a whole occupies a large space, and the distance between adjacent fruit trees must be large enough to achieve the overall rotation of the equipment for spraying. The spraying efficiency is low and the time is long. At the same time, the existing equipment is large in size and is relatively space-constrained during use and storage. Summary of the invention
