Description

Technical Field

[0001] The utility model relates to a trunk drilling and medicine injection device for preventing and controlling forest diseases and insect pests, belonging to the technical field of forest prevention and control. Background Art

[0002] Pest and disease control is to reduce or prevent pathogenic microorganisms and pests from harming crops or humans and livestock by taking certain artificial means. It can generally be divided into chemical control using chemicals such as pesticides and physical control using physical energy such as light or rays or building barriers. Nowadays, the means of pest and disease control have been widely used. In order to enhance the defense capabilities of trees themselves, drilling holes and injecting medicines are used to effectively control pests inside them.

[0003] A common tree trunk drilling and injection device consists of a drill bit and an injection mechanism. When in use, the drill bit is driven by a motor to rotate to drill holes in the tree trunk. In order to facilitate injection, a through hole is opened on the surface of the drill bit. After the drill bit drills into the tree trunk, the injection mechanism is used to inject medicine into the interior, so that the medicine flows out from the through hole on the surface of the drill bit, thereby completing the injection.

[0004] However, this method generates a large amount of sawdust when the drill bit drills holes in the tree trunk, and the through holes opened for the convenience of injecting medicine are easily clogged by the sawdust, resulting in that the medicine cannot flow out smoothly during the subsequent injection, and the sawdust continuously enters the inside of the drill bit through the through holes and is inconvenient to clean, resulting in poor effect of drilling and injecting medicine, and cannot meet the working requirements of drilling and injecting medicine. Therefore, a tree trunk drilling and injecting device for forest pest control is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is as follows: in the prior art, a large amount of wood chips will be generated when a drill bit is drilling a tree trunk, and the through holes opened for the convenience of injecting medicine are easily clogged by the wood chips, resulting in that not only the medicine cannot flow out smoothly during the subsequent injection of medicine, but also the wood chips continue to enter the interior of the drill bit from the through holes and are inconvenient to clean, resulting in poor effect of drilling and injecting medicine, and failure to meet the working requirements of drilling and injecting medicine.

[0006] In order to solve the above technical problems, the utility model provides a trunk drilling and drug injection device for forest pest control, comprising:

[0007] A drilling gun body, wherein a rotating shaft is connected to the left side of the drilling gun body, a drill bit is coaxially mounted on the left end of the rotating shaft, the interior of the drill bit is a hollow structure, and a drug injection hole is circumferentially opened on the left side of the exterior of the drill bit;

[0008] A drug injection cartridge is installed at the rear of the drilling gun body, a hose is connected to the left end of the drug injection cartridge, and a liquid inlet pipe is installed on the right side of the top of the drill bit;

[0009] An inner rod is inserted into the drill bit, a sealing sheet is circumferentially connected to the outer left side of the inner rod, a stepped groove is provided on the inner left side of the drill bit, a sealing disk is coaxially mounted on the left end of the inner rod, and a first spring is connected to the left side of the sealing disk;
