[0002] Tree nematodes are common pests that severely impact tree growth and health. Traditional control methods primarily rely on chemical spraying, soil treatment, or trunk injection. However, these methods suffer from low pesticide utilization, environmental pollution, and difficulty in precise application. Trunk injections often use simple syringes with limited functionality and practicality. Therefore, there is a need to design a needle capable of precisely and efficiently injecting pesticides into the tree. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a needle for controlling tree nematodes, characterized in that it includes a bolt joint, a drug delivery tube, and a needle. One end of multiple drug delivery tubes is connected to the bolt joint, and the other end of the drug delivery tube is detachably connected to the needle. A disinfection tube is fixedly connected to the bolt joint. A disinfectant slow-release pack is provided on the disinfectant tube. Sodium hypochlorite is embedded in the disinfectant slow-release pack through gelatin microcapsules. A disinfection interface is provided on the drug delivery tube to cooperate with the disinfection tube. The needle includes an integrally formed connecting section, a needle tube section, and a conical section connected in sequence. The connecting section is detachably connected to the drug delivery tube. A spiral guide groove is formed along the axial direction in the needle tube section. Multiple injection holes are formed on the periphery of the conical section.

[0005] Preferably, the upper side wall of the disinfection tube is provided with a water inlet, the top of the disinfection tube is closed, the bottom of the disinfection tube is provided with a connector that mates with the disinfection interface, the disinfection interface is provided with an elastic sealing plug, the disinfectant slow-release pack is provided with an opening for replacing the disinfectant, and the disinfectant slow-release pack is provided with a sealing sleeve for sealing the opening, which facilitates the replacement of the disinfectant without leakage.

[0006] Preferably, the outlet end of the drug delivery tubing is fixedly connected to a threaded sleeve, the connecting section has an external thread that engages with the threaded sleeve, and the outer wall of the needle tube section has a scale line for observing the insertion depth into the tree trunk.

[0007] Preferably, the infusion tubing is equipped with a flow regulator for adjusting the flow rate, which is the same as the flow regulator used with an intravenous syringe. The flow rate is controlled by squeezing or releasing the flow channel size of the infusion tubing.

[0008] This utility model has the following advantages compared with the prior art: 1. This utility model has a scientific and reasonable structural design, strong practicality, and can simultaneously administer intravenous infusions to different points, effectively improving the efficiency of intravenous infusion prevention and treatment. The needle is detachable for easy replacement and maintenance, and the manufacturing cost is low, making it suitable for widespread use.

[0009] 2. This utility model disinfects and cleans each delivery hose by injecting water into the disinfection tube and releasing disinfectant through the disinfectant slow-release pack, which is convenient for repeated use and avoids cross-infection of trees.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0013] Explanation of reference numerals in the attached figures: Detailed Implementation

[0014] like Figure 1 and Figure 2 As shown, this utility model includes a bolted connector 1, a drug delivery tubing 2, and a needle 4. The bolted connector 1 is connected to a drug storage container. One end of each of the three drug delivery tubing 2 is connected to the bolted connector 1, and the other end of the drug delivery tubing 2 is detachably connected to the needle 4. A sterilization tube 5 is fixedly connected to the bolted connector 1. A disinfectant slow-release pack 8 is provided on the sterilization tube 5. Sodium hypochlorite is embedded in the disinfectant slow-release pack 8 through gelatin microcapsules. A sterilization interface 6 is provided on the drug delivery tubing 2 to cooperate with and connect to the sterilization tube 5. The needle 4 includes an integrally formed connecting section 4-1, a needle tube section 4-2, and a conical section 4-3 connected in sequence. The connecting section 4-1 is detachably connected to the drug delivery tubing 2. A spiral guide groove is formed along the axial direction in the needle tube section 4-2. Multiple injection holes 4-4 are formed on the periphery of the conical section 4-3.

[0015] In this embodiment, a water inlet 7 is provided on the upper side wall of the disinfection tube 5, the top of the disinfection tube 5 is closed, and a connector 9 that mates with the disinfection interface 6 is provided at the bottom of the disinfection tube 5. An elastic sealing plug is provided on the disinfection interface 6, and an opening for replacing the disinfectant is provided on the disinfectant slow-release pack 8. A sealing sleeve for sealing the opening is provided on the disinfectant slow-release pack 8, which facilitates the replacement of the disinfectant without leakage.

[0016] In this embodiment, the outlet end of the drug delivery tubing 2 is fixedly connected to a threaded sleeve 3, the connecting section 4-1 is provided with an external thread that is threadedly engaged with the threaded sleeve 3, and the outer wall of the needle tube section 4-2 is provided with a scale line 4-5 for observing the insertion depth into the tree trunk.

[0017] In this embodiment, the infusion tubing 2 is equipped with a flow regulator for adjusting the flow rate, which is the same as the flow regulator used with an intravenous syringe. The flow rate is controlled by squeezing or releasing the flow channel size of the infusion tubing 2.

[0018] In this embodiment, the spiral guide groove has a depth of 0.8 mm and a pitch of 2 mm, which causes the liquid medicine to swirl.

[0019] In use, secure the pesticide storage container to the tree trunk, connect the bolt connector 1, and insert the needle 4 diagonally downwards into the selected position on the trunk. Control the insertion depth of the needle 4 using the scale lines 4-5. Ensure the infusion tubing 2 hangs smoothly to guarantee gravity flow efficiency. Open the flow regulator to release the pesticide. As the pesticide passes through the spiral guide groove, it creates a swirling flow, promoting full contact between the pesticide and the tree trunk tissue, reducing leakage and waste, and ensuring smooth injection. Simultaneously, different flow regulators can be used to control the flow rate of different infusion tubing 2 to meet the pest control needs of different parts of the tree.

[0020] After the injection is completed, connect the disinfection interface 6 and the connector 9, and inject water into the disinfection tube 5 through the water inlet 7. The water flows through the disinfectant slow-release pack 8 to release sodium hypochlorite to clean and disinfect each infusion tubing 2 and needle 4. Inverting the infusion tubing 2 can also disinfect the bolt joint 1 for easy use next time.

[0021] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any simple modifications, alterations, and equivalent changes made to the above embodiments based on the technical essence of this utility model shall still fall within the protection scope of this utility model.
