Description

Technical Field

[0001] The utility model relates to the technical field of forestry protection, and more specifically, to a forestry tree trunk drilling device. Background Art

[0002] Pest control is an important part of forestry management work. The method of injecting drugs into the tree trunk for pest control is simple and effective, with the advantages of less pesticide consumption, less environmental pollution, and less harm to humans and livestock. Compared with the spraying method for pest control, a large amount of pesticides can be saved. For the method of injecting drugs into the tree trunk for pest control, the method of drilling holes first and then injecting drugs is adopted. Currently, most trees are drilled first and then drugs are injected. In the prior art, there is also a method of combining tree trunk drilling and liquid medicine injection by arranging an injection cylinder inside the drill bit to reduce the work intensity. However, this injection method also has deficiencies. During the process of drilling holes in the tree trunk, there are usually tree debris on the drill bit.
