Description

Technical Field

[0001] This utility model relates to the field of pine trunk injection technology, specifically a protective kit for trunk injection. Background Technology

[0002] Qujing is located in eastern Yunnan Province, China. It has a subtropical plateau monsoon climate with four distinct seasons and abundant vegetation. Common trees include Yunnan pine and Huashan pine. During their normal growth, pine trees are often invaded by scale insects, nymphs, mites, and mite eggs. If not treated in time, they can lead to poor growth or even death. Every year, local forest rangers inject lime sulfur into pine trees to reduce pests and diseases. When injecting the trunk of trees, especially tall trees like pine, the drilling position is 1.2 to 1.5 meters above the ground, at a 45° downward angle.

[0003] Since injecting pesticide into pine trees involves drilling downwards, the injection syringe needs to be secured. As disclosed in the specification of existing technology CN219803097U, paragraphs 0018-0019, "...when manually pushing the injection plunger to inject heated lime-sulfur mixture into the pine tree, the rotating impeller agitates the lime-sulfur mixture, allowing it to be heated more evenly...tightening the four threaded bolts brings them into contact with the pine tree, further improving the stability of the clamping and securing. The rubber block increases the friction between the threaded bolts and the trunk; simultaneously, as the trunk grows thicker, the rubber block gradually deforms, thus..." Provide sufficient growth space for the tree trunk under stable conditions. This disclosed the limitation of the injection syringe. However, as is well known, trees have a woody structure, which is different from the human body. Once a hole is drilled in a pine tree, it will not be closed in the short term. The inner diameter of the hole must be larger than the diameter of the injection needle. This results in a gap between the needle and the hole. Although the aforementioned technical solution can fix the syringe and thus fix the needle in the hole, the aforementioned technical solution cannot protect the gap between the hole and the needle. The hole gap will become a channel for the tree's moisture and odor to leak out. A considerable part of the injected medicine will evaporate from the gap, causing the loss of efficacy and reducing the treatment effect on the pine tree. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a protective kit for injecting medicine into tree trunks. This kit has advantages such as blocking the gap between the injection needle and the drilled hole in the tree trunk to prevent the medicine from evaporating, thus solving the aforementioned technical problems.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a protective kit for injecting medicine into tree trunks, comprising a rubber sleeve that contacts a drilled hole in the tree trunk, the inner side of the rubber sleeve wrapping an injection needle, forming a filler between the drilled hole in the tree trunk and the injection needle, multiple slits being opened at the bottom of the rubber sleeve, the multiple slits dividing the bottom of the rubber sleeve into multiple rubber strips, and a sealing structure being provided on the inner side of the rubber sleeve. Includes a sealing block, with a minimum of one sealing block, which is installed on the inner top or inner bottom of the rubber sleeve.

[0006] As a preferred technical solution of this utility model, both the rubber sleeve and the sealing block are made of natural rubber.

[0007] As a preferred technical solution of this utility model, the rubber sleeve is a hollow cylinder with four slits. The slits are equilateral triangles with a smaller top and a larger bottom. The slits divide the bottom of the rubber sleeve into four rubber strips. The rubber strips are isosceles trapezoids with a larger top and a smaller bottom. After the four rubber strips enter the drill hole, they gradually converge and shrink into a cone shape with a smaller front and a larger back.

[0008] As a preferred technical solution of this utility model, the sealing structure includes four sealing blocks, which are fixedly connected to the bottom of the inner wall of the rubber strip, i.e., the inner side of the rubber sleeve, by means of heat fusion connection.

[0009] As a preferred technical solution of this utility model, the sealing block is an isosceles triangle, and the four sealing blocks combine into a circle when the rubber strip contracts.

[0010] As a preferred technical solution of this utility model, the rubber sleeve is a hollow inverted cone shape with a smaller top and a larger bottom and open top and bottom. The number of slits is four. The slits are equilateral triangles with a smaller top and a larger bottom. The slits divide the bottom of the rubber sleeve into four rubber strips. The rubber strips are quadrilaterals with equal width at the top and bottom. The four rubber strips cover the surface of the tree trunk where the drilled holes are made.

[0011] As a preferred technical solution of this utility model, the sealing structure includes a sealing block, which is a cylinder and located at the top of the inner side of the rubber sleeve. The top surface of the sealing block is connected to a skin, which covers the opening on the top surface of the rubber sleeve and is fixedly connected with glue.

[0012] As a preferred technical solution of this utility model, the top surface of the skin is also provided with a notch for inserting the injection needle.

[0013] Compared with the prior art, this utility model provides a protective kit for trunk injection, which has the following beneficial effects: This invention involves inserting the bottom of a rubber sleeve into a drilled hole. At this point, four rubber strips initially contact the inside of the hole. Since the inner diameter of the drill hole is smaller than the diameter of the rubber sleeve, the four rubber strips begin to press against each other. Because of the slits, the four rubber strips converge into a cone shape, smaller at the front and larger at the back, within the drill hole. As the four rubber strips converge, the four sealing blocks are also pulled together, eventually forming a single unit. This combined state of the four sealing blocks seals the drill hole. The injection needle then passes through the four sealing blocks and continues to penetrate the drill hole until it reaches the base of the pine trunk at the bottom of the hole for injection. The seal formed by the four sealing blocks effectively seals and protects the liquid inside the drill hole, preventing the liquid from evaporating and blocking the gap between the injection needle and the drilled hole.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-7 A protective kit for injecting medicine into tree trunks includes a rubber sleeve 1 that contacts a drilled hole in the tree trunk. The inner side of the rubber sleeve 1 is wrapped with an injection needle, forming a filler between the drilled hole in the tree trunk and the injection needle. Multiple slits 101 are opened at the bottom of the rubber sleeve 1, which divide the bottom of the rubber sleeve 1 into multiple rubber strips 102. A sealing structure is also provided on the inner side of the rubber sleeve 1. Includes sealing block 2, the number of sealing blocks 2 is at least one, and sealing block 2 is installed on the inner top or inner bottom of rubber sleeve 1.

[0020] Furthermore, both the rubber sleeve 1 and the sealing block 2 are made of natural rubber.

[0021] Natural rubber has excellent elasticity. The rubber sleeve 1 and sealing block 2 made of natural rubber can adapt to different sizes of drill hole gaps. At the same time, natural rubber is an organic material that can be decomposed by the natural environment within six months, making it green and environmentally friendly.

[0022] Furthermore, the rubber sleeve 1 is a hollow cylinder with four slits 101. Each slit 101 is an equilateral triangle with a smaller top and a larger bottom. The slits 101 divide the bottom of the rubber sleeve 1 into four rubber strips 102. Each rubber strip 102 is an isosceles trapezoid with a larger top and a smaller bottom. After entering the drill hole, the four rubber strips 102 gradually converge and shrink into a cone shape with a smaller front and a larger back.

[0023] The equilateral triangular opening makes all four rubber strips 102 have a shape that is larger at the top and smaller at the bottom. As a result, when the four rubber strips 102 are brought together, they will inevitably form a cone shape that is smaller at the front and larger at the back. The cone shape corresponds to the fact that the front part can be inserted smoothly into the drill hole, while the back part gradually thickens. At this time, the injection needle penetrates the rubber sleeve 1, forming a volume larger than the inner diameter of the drill hole. However, because the rubber strips 102 are made of natural rubber and are flexible, they can be compressed, thus forming a jamming shape between them and the injection needle, completely blocking the drill hole.

[0024] A hollow cylinder is used as the rubber sleeve 1, and with four slits 101, its bottom is divided into four rubber strips 102, as shown in the instruction manual. Figure 1 As shown, four rubber strips 102 are staggered with the slits 101. When the bottom of the rubber sleeve 1 is inserted into the drill hole, the four rubber strips 102 first come into contact with the inside of the drill hole. At this time, the four rubber strips 102 enter the drill hole at the same time. Since the inner diameter of the drill hole is smaller than the diameter of the rubber sleeve 1, the four rubber strips 102 begin to squeeze each other. Because of the slits 101, the four rubber strips 102 move closer together to form a cone shape that is smaller in the front and larger in the back inside the drill hole. At the same time, the inner side of the four rubber strips 102 is also connected to the skeleton 3 by heat fusion. The skeleton 3 is a vertical rod and is embedded inside the rubber strips 102. The skeleton 3 is made of wood or bamboo. Embedding the skeleton 3 inside the rubber strips 102 makes it both soft and hard, ensuring that the rubber strips 102 maintain their hardness when inserted into the drill hole and will not twist between each other due to the small inner diameter of the drill hole.

[0025] Furthermore, the sealing structure includes four sealing blocks 2, which are fixedly connected to the bottom of the inner wall of the rubber strip 102, i.e., the inner side of the rubber sleeve 1, by means of heat fusion connection.

[0026] When the four rubber strips 102 are closed, the four sealing blocks 2 will also be driven to move closer together and eventually become a single piece, as shown in the instruction manual. Figure 2 As shown, the four sealing blocks 2 together form a seal for the drill hole. Then, the injection needle passes through the inside of the four sealing blocks 2 and continues to be inserted into the inside of the drill hole until it contacts the base of the pine trunk at the bottom of the inside of the drill hole to inject the medicine. At this time, the seal formed by the four sealing blocks 2 can seal the medicine at the bottom of the inside of the drill hole and prevent it from evaporating or volatilizing.

[0027] Furthermore, the sealing block 2 is an isosceles triangle, and the four sealing blocks 2 combine into a circle when the rubber strip 102 contracts.

[0028] As per the instruction manual Figure 3 As shown, the four sealing blocks 2 are divided into four equal parts of a complete circle. Each rubber strip 102 is bonded to one sealing block. When the rubber strip 102 closes, the corresponding sealing block 2 will also close. Furthermore, the rubber sleeve 1 is a hollow inverted cone shape with a smaller top and a larger bottom and openings at both the top and bottom. There are four slits 101, and the openings are equilateral triangles with a smaller top and a larger bottom. The openings divide the bottom of the rubber sleeve 1 into four rubber strips 102. The rubber strips 102 are quadrilaterals with equal width at the top and bottom. The four rubber strips 102 cover the surface of the tree trunk where the drilled holes are made.

[0029] Furthermore, the sealing structure includes a sealing block 2, which is a cylinder located at the top of the inner side of the rubber sleeve 1, and the top surface is connected to the skin 5. The skin 5 covers the opening on the top surface of the rubber sleeve 1 and is fixedly connected with glue.

[0030] Furthermore, a notch 501 is provided on the top surface of the skin 5, which is used for the insertion of the injection needle.

[0031] The injection needle is inserted directly into the skin 5 and then through the sealing block 2 to enter the borehole, eventually reaching the base of the pine trunk. At this point, the sealing block 2, made of natural rubber, directly contracts and closes the opening of the injection needle, forming a complete seal at the borehole opening to prevent the liquid from evaporating.

[0032] Example 1 In this embodiment, a hollow cylinder is used as the rubber sleeve 1, and with four slits 101, its bottom is divided into four rubber strips 102, as shown in the attached instruction manual. Figure 1 As shown, the four rubber strips 102 and the slits 101 are staggered.

[0033] In practical use, select a smooth, undamaged location on the pine trunk, 1.2-1.5 meters above the base of the trunk, free of insect holes. Use a 4-6 mm drill bit to drill a hole at a 45° downward angle to a depth of approximately 3-5 mm. cm, reaching the woody part, and then inserting the bottom of the rubber sleeve 1 into the drill hole. At this time, the four rubber strips 102 first come into contact with the inside of the drill hole. The four rubber strips 102 enter the drill hole at the same time. Since the inner diameter of the drill hole is smaller than the diameter of the rubber sleeve 1, the four rubber strips 102 begin to squeeze against each other. Because of the slit 101, the four rubber strips 102 move closer together to form a cone shape that is smaller at the front and larger at the back inside the drill hole. At the same time, the inner side of the four rubber strips 102 is also connected to the skeleton 3 by heat fusion. The skeleton 3 is a vertical rod and is embedded inside the rubber strips 102. The skeleton 3 is made of wood or bamboo. Embedding the skeleton 3 inside the rubber strips 102 makes it flexible yet rigid, ensuring that the rubber strips 102 maintain their rigidity when inserted into the drill hole and will not twist between the rubber strips 102 due to the small inner diameter of the drill hole. The four sealing blocks 2 will also be moved closer together when the four rubber strips 102 are closed, eventually becoming a whole piece, as shown in the instruction manual. Figure 2As shown, the four sealing blocks 2 together form a seal for the drill hole. Then, the injection needle passes through the inside of the four sealing blocks 2 and continues to be inserted into the inside of the drill hole until it contacts the base of the pine trunk at the bottom of the inside of the drill hole to inject the medicine. At this time, the seal formed by the four sealing blocks 2 can seal and protect the medicine at the bottom of the inside of the drill hole, preventing it from evaporating or volatilizing. Furthermore, the injection needle is connected to the injection syringe, and the corresponding injection syringe itself is fixed to the pine trunk by a fixing structure, as shown in the utility model CN219803097U printed in this application. After the injection is completed, the fixing structure is removed, and the syringe is pulled out along with the needle. Finally, the rubber strip 102 is grabbed and the entire rubber sleeve 1 is pulled out to complete the cleaning work. At this time, the rubber sleeve 1 can be reused or directly discarded in the natural environment to participate in decomposition and ultimately be harmlessly treated.

[0034] When in use, the bottom of the rubber sleeve 1 is inserted into the drill hole. At this time, the four rubber strips 102 first come into contact with the inside of the drill hole. The four rubber strips 102 enter the drill hole at the same time. Since the inner diameter of the drill hole is smaller than the diameter of the rubber sleeve 1, the four rubber strips 102 begin to squeeze each other. Because there is a slit 101, the four rubber strips 102 come together to form a cone shape that is smaller in the front and larger in the back inside the drill hole. When the four rubber strips 102 come together, the four sealing blocks 2 are also driven to come together and eventually become a whole piece. The four sealing blocks 2 form a seal for the drill hole. Then, the injection needle passes through the inside of the four sealing blocks 2 and continues to be inserted into the inside of the drill hole until it contacts the base of the pine trunk at the bottom of the inside of the drill hole to inject medicine. At this time, the sealing state formed by the four sealing blocks 2 can seal and protect the medicine at the bottom of the inside of the drill hole.

[0035] Example 2 In this embodiment, the rubber sleeve 1 is a hollow inverted cone shape with a smaller top and a larger bottom and openings at both the top and bottom. Together with the skin 5 at the top opening and the sealing block 2 below it, it forms a structure with an isosceles trapezoidal cross section, with the upper end sealed and the lower end slotted 101. In practical use, select a smooth, undamaged, and insect-free location on the trunk of a pine tree, 1.2-1.5 meters above the base of the trunk. Use a 4-6 mm drill bit to drill a hole at a 45° angle downwards to a depth of about 3-5 cm, reaching the xylem. Then, spread the rubber sleeve 1 around the drill hole. At this time, the four rectangular rubber strips 102 spread out in all directions, forming an octopus-like shape, exposing the sealing block 2 on the inner top. Insert the sealing block 2 into the drill hole. At this time, the opening of the drill hole is directly sealed by the sealing block 2. Then, insert the injection needle into the notch 501. The injection needle passes through the bark 5 through the notch 501 and pierces into the sealing block 2, and then passes through the sealing block into the drill hole. As the injection needle continues to be inserted, it eventually reaches the base of the pine trunk. At this time, the whole sealing block 2 made of natural rubber directly contracts and closes the wound of the injection needle, forming an overall seal at the opening of the drill hole to prevent the liquid from evaporating. Furthermore, in this embodiment, the sealing block 2 is directly inserted into the drill hole to form a plug, thus protecting the needle tip and the gap in the drill hole. Simultaneously, the injection needle is connected to the injection syringe, and the corresponding injection syringe itself is fixed to the pine trunk by a fixing structure, as shown in utility model CN219803097U printed in this application. Because the fixing structure positions the syringe during injection, the syringe cannot be retracted, which also presses down on the rubber strip 102, making it tightly adhere to the trunk surface. When the needle is removed after injection, the rubber strip 102 loses its pressure, as shown in the appendix to the instruction manual. Figure 5 As shown, simply grab the rubber strip 102 and pull out the entire rubber sleeve 1 to complete the cleaning work. At this point, the rubber sleeve 1 can be reused or directly discarded in the natural environment to participate in decomposition and ultimately be rendered harmless.

[0036] When in use, spread the rubber sleeve 1 around the trunk around the drill hole. At this time, the four rectangular rubber strips 102 spread out in all directions, forming an octopus-like shape, and exposing the sealing block 2 on the top of its inner side. Insert the sealing block 2 into the drill hole. At this time, the opening of the drill hole is blocked by the sealing block 2, and is directly sealed. Then, insert the injection needle into it through the notch 501. The injection needle passes through the skin 5 through the notch 501 and pierces into the sealing block 2, and then passes through the sealing block into the drill hole. As the injection needle continues to be inserted, it eventually penetrates into the base of the pine trunk. At this time, the whole sealing block 2 made of natural rubber directly contracts and closes the wound of the injection needle, and together with the plug at the opening of the drill hole, it forms an overall seal to prevent the liquid from evaporating.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
