Description

Technical Field

[0001] This utility model relates to the technical field of tree trunk pest control equipment, and in particular to a high-pressure tree trunk micro-hole injection needle. Background Technology

[0002] Tree trunk injection involves forcibly injecting insecticides, fungicides, micronutrients, etc., into the tree trunk using an injection gun. This allows the solution to directly enter the tree and be transported, thereby promoting growth, increasing yield, and improving quality.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] Existing injection needle designs have several shortcomings that limit their effectiveness in practical applications. Specifically, most existing injection needles are cylindrical structures with a diameter of 5mm-8mm. This relatively large diameter causes significant damage to trees, hindering the healing of wood fibers and increasing the difficulty of removal. Furthermore, they are only compatible with a specific drive mechanism; for example, they can only be used with high-pressure injection guns and are incompatible with other types of drive mechanisms such as electric hammers or manual cones, limiting the flexibility and applicability of the injection needles.

[0005] For example, application number CN202420550400.9 discloses a split-type needle for high-pressure injection of micropores in trees.

[0006] In view of the above, this utility model is hereby proposed. Utility Model Content

[0007] The purpose of this invention is to provide a high-pressure tree trunk micro-hole injection needle to solve the technical problems of existing injection needles, such as design defects that cause significant damage to trees, hinder the healing of wood fibers, and make removal difficult. The preferred technical solutions provided by this invention and their various technical effects are detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] This utility model provides a high-pressure tree trunk microporous injection needle, including a needle and a needle holder for mounting the needle. The diameter of the needle gradually decreases in the direction away from the needle holder, forming a conical structure, and its diameter is less than or equal to 3mm. The needle holder can be assembled with various driving devices.

[0010] Preferably, the diameter of the needle is 2.5mm-3mm.

[0011] Preferably, the tip of the needle has at least three inclined surfaces arranged circumferentially along the needle tip to form a tip structure.

[0012] Preferably, the tip of the needle has four inclined surfaces arranged circumferentially along the needle tip to form a pointed tip structure.

[0013] Preferably, the needle is 4 cm long.

[0014] Preferably, the needle has multiple drug dispensing holes, which are connected to the drug delivery channel of the needle.

[0015] Preferably, the needle holder is provided with an annular groove for quick assembly with a high-pressure injection gun.

[0016] Preferably, the needle holder is provided with an annular protrusion, which is located between the needle and the annular groove, for assembly with the assembly interface of an electric hammer or a manual cone.

[0017] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0018] This invention effectively avoids the design flaws of existing injection needles, which cause significant damage to trees, hinder wood fiber healing, and are difficult to remove. This invention provides a high-pressure trunk micro-injection needle, including a needle head and a needle holder for mounting the needle. The diameter of the needle head gradually decreases towards the direction away from the needle holder, forming a conical structure, and its diameter is less than or equal to 3mm. The needle holder can be assembled with various driving devices, including electric hammers, manual cones, or high-pressure injection guns. The conical structure of the needle, with a diameter less than or equal to 3mm, ensures effective drug injection while minimizing the wound area on the tree during insertion, promoting rapid wood fiber healing. Furthermore, the conical design, due to its gradually decreasing diameter, makes it easier to remove from the trunk, reducing resistance and additional damage to the tree during removal. In addition, the needle holder can be assembled with various driving devices, improving the flexibility and applicability of the injection needle. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-3 As shown, the present invention provides a high-pressure trunk micro-hole injection needle 1, including a needle 1 and a needle holder 2 for mounting the needle 1. The diameter of the needle 1 gradually decreases in the direction away from the needle holder 2, forming a conical structure, and its diameter is less than or equal to 3mm. The needle holder 2 can be assembled with various driving devices, including electric hammers, manual cones or high-pressure injection guns.

[0028] Compared to existing injection needles, which are mostly cylindrical with a diameter of 5mm-8mm, causing significant damage to the tree and hindering the healing of wood fibers, as well as increasing the difficulty of removal, the needle 1 of this invention is designed as a conical structure with a diameter of 3mm or less. This design ensures effective drug injection while minimizing the wound area on the tree during insertion, promoting rapid healing of wood fibers. Furthermore, the conical design, with its gradually decreasing diameter, makes it easier to remove from the trunk, reducing resistance and additional damage to the tree. In addition, the needle holder 2 can be assembled with various driving devices, improving the flexibility and applicability of the injection needle 1.

[0029] As an optional implementation, the diameter of the needle 1 is 2.5mm-3mm.

[0030] Compared with the cylindrical needle 1 with a diameter of 5mm-8mm in the existing technology, the needle 1 with a diameter of 2.5mm-3mm can form micropores on the tree trunk. While ensuring the effect of drug injection, it can greatly reduce the damage to wood fibers and facilitate the rapid recovery of trees.

[0031] As an optional implementation, the tip of the needle 1 has at least three inclined surfaces 11 arranged circumferentially along the needle 1 so that the tip of the needle 1 forms a tip structure.

[0032] This design enhances the penetrating power of needle 1, making it easier for needle 1 to penetrate the bark and phloem and enter the xylem when inserted into the tree trunk.

[0033] As an optional implementation, the tip of the needle 1 has four inclined surfaces 11 at its front end, which are arranged circumferentially along the needle 1 so that the tip of the needle 1 forms a tip structure.

[0034] Compared to the two opposing inclined surfaces 11 in the prior art, the needle 1 of this invention has four inclined surfaces 11 at its front end, forming a sharper tip structure, which allows the needle 1 to enter the tree trunk more smoothly, reducing resistance, improving the penetration ability of the needle 1, and reducing tearing of wood fibers.

[0035] As an alternative implementation, the needle 1 is 4 cm long, matching the depth of the wood in the tree.

[0036] This design allows the needle 1 to be inserted into the key parts of the tree that need to be injected with the medicine, while avoiding unnecessary damage to the tree caused by an excessively long needle 1.

[0037] As an optional implementation, the needle 1 is provided with a plurality of drug outlet holes 12, which are connected to the drug delivery channel 13 of the needle 1.

[0038] Furthermore, the number of dispensing holes 12 can be two, four, or six, and can be designed according to usage requirements.

[0039] As shown in the figure, this embodiment has four drug outlet holes 12, each of which is connected to the drug delivery channel 13. Two drug outlet holes 12 arranged opposite each other form a group, and the two groups are staggered along the axial direction.

[0040] Once the needle 1 is inserted into the tree trunk, the medicine enters the needle 1 through the drug delivery channel 13 and is evenly sprayed out from the four drug outlet holes 12, thus injecting the medicine.

[0041] It should be noted that this invention does not improve the drug delivery channel 13 of the needle 1 and needle seat 2, but adopts existing technology, which will not be elaborated here.

[0042] As an optional implementation, the needle holder 2 is provided with an annular groove 21 for quick interface assembly with a high-pressure injection gun.

[0043] The annular groove 21 is a standardized assembly point. After the needle holder 2 is inserted into the quick-connect interface of the high-pressure injection gun, the two will be tightly connected. At this time, the locking component of the quick-connect interface pops out and engages with the annular groove 21 to ensure a stable connection between the needle holder 2 and the high-pressure injection gun, so as to avoid relative movement between the needle holder 2 and the high-pressure injection gun during the high-pressure injection process.

[0044] As an optional implementation, the needle holder 2 is provided with an annular protrusion 22, which is located between the needle 1 and the annular groove 21, for assembly with the assembly interface of an electric hammer or a manual cone.

[0045] The annular protrusion 22 is also a standardized assembly point that mates with the assembly interface of an electric hammer or a manual cone.

[0046] When it is necessary to use an electric hammer or a manual awl to insert the needle 1 into the tree trunk, simply align its mounting interface with the annular protrusion 22 on the needle holder 2 and assemble it.

[0047] The design of the annular protrusion 22 and the annular groove 21 improves the compatibility between the needle holder 2 and different driving devices.
