Description

Technical Field

[0001] This utility model relates to the field of garden maintenance technology, and in particular to a device for treating blockages in tree injection holes. Background Technology

[0002] Garden plants, as an important component of urban greening, play an irreplaceable role in maintaining the ecological environment and beautifying the urban landscape. However, during their growth, garden plants often face threats from various biotic and abiotic factors, among which insect pests are particularly prominent. Insect pests not only directly affect the normal growth of plants but can also spread diseases and even lead to plant death.

[0003] Traditional canopy spraying methods for pest control easily lead to large amounts of pesticide solution diffusing into the air, dripping onto the ground, or polluting water sources. This not only wastes pesticides, pollutes the environment, damages the ecosystem, and affects biodiversity, but also poses a health risk to applicators and passersby through inhalation and contact. To address pest and disease control more scientifically and rationally, the perforation-injection technique has emerged. This technique, characterized by its labor-saving, time-saving, low-cost, and significant effects, has been widely used in the control of pests in garden plants, especially for trunk-boring and piercing-sucking pests that are difficult to control using conventional methods. The core operation of perforation-injection involves mechanically drilling holes at the base of the trunk to directly inject the pesticide into the tree. During this process, the pesticide can quickly penetrate and distribute evenly throughout the tree's tissues. Utilizing the tree's own transpiration, the pesticide solution is effectively transported to key areas such as newly emerging leaves, buds, and fruits. When pests feed on these parts, they ingest high concentrations of the pesticide, leading to poisoning and death.

[0004] While injection drilling brings significant pest control benefits, this procedure inevitably leaves injection holes at the base of the trunk, causing mechanical damage. If these holes are not properly treated, they can easily become new entry points for pests and diseases, leading to tree rot or dieback. Currently, the common approach is to fill the holes with soil to seal and protect them. However, this method does not provide an effective environment for wound healing and recovery; in fact, the microorganisms and moisture in the soil may exacerbate the risk of infection. Therefore, improving the treatment of injection holes is crucial for enhancing the overall effectiveness of injection drilling technology. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a device for treating blockages in tree injection holes, wherein a core rod is sleeved in the cavity of a syringe and its upper end extends a certain distance beyond the upper handle of the syringe; a stopper is sleeved in the syringe and abuts against the lower end of the syringe; a through hole is provided in the center of the stopper; both the lower ends of the syringe and the stopper are conical surfaces with multiple evenly distributed contraction slits; a tube clamp is provided in the middle of the conical surface at the lower end of the syringe; first rollers are symmetrically arranged on both sides of the syringe; a belt passes over the upper edge of the first rollers, with one end connected to the tube clamp and the other end connected to one end of the handle; push rods are symmetrically arranged on both sides of the core rod and are located above the connection point between the first roller and the end of the belt; and the healing agent is placed in the cavity of the syringe and the stopper.

[0007] In the preferred embodiment, the lower end of the syringe is provided with multiple first contraction slits, and the two ends extend to the starting point and the ending point of the conical surface, respectively. The first roller is rotatably connected to the handle through the first roller frame. A through hole is provided between the first roller on the handle and the connection point of the belt end. The lower end of the push rod passes through the through hole and abuts against the belt.

[0008] In the preferred embodiment, the second contraction slit at the lower end of the stopper is in an open state under natural conditions. After being squeezed and contracted, it abuts against the lower end of the inner wall of the syringe and forms a conical surface after contraction. The outer diameter of the cylindrical part at the upper end of the stopper is equal to the inner diameter of the syringe, and the total length of the stopper is not greater than the length of the conical surface of the syringe.

[0009] The stopper is made of wood.

[0010] In the preferred embodiment, the upper end of the core rod is provided with a push plate, and the lower end is provided with an isolation plug. The isolation plug is a series of conical surfaces that are stacked on top of each other, and its maximum outer diameter is equal to the inner diameter of the syringe.

[0011] In the preferred embodiment, the sum of the lengths of the core rod and the isolation plug is greater than the length of the cylindrical tube above the conical surface of the syringe.

[0012] In the preferred embodiment, the clamp consists of two semicircular rings, with two elastic elements symmetrically arranged inside. One end of the elastic element is connected to one end of one semicircular ring, and the other end is connected to one end of the other semicircular ring. The elastic element drives the clamp to press against the tapered surface at the lower end of the syringe.

[0017] This utility model provides a device for treating blocked tree injection holes. The device comprises a core rod and a stopper sleeve housed within a syringe cavity. The stopper sleeve rests against the lower end of the syringe, with a through hole at its center. Both the syringe and the stopper sleeve have tapered surfaces with multiple evenly distributed contraction slits at their lower ends. A clamp is located in the center of the tapered surface at the lower end of the syringe. First rollers are symmetrically positioned on both sides of the syringe. A belt passes over the upper edge of the first rollers, with one end connected to the clamp and the other end connected to one end of the handle. Push rods are symmetrically positioned on both sides of the core rod, located above the connection point between the first rollers and the belt end. A healing agent is placed within the cavity of the syringe and the stopper sleeve. After the core rod presses down to inject the healing agent, the push rod pushes the belt, causing the clamp to move upwards. Simultaneously, the core rod pushes the stopper sleeve out of the lower end of the syringe, securing it within the tree's injection hole. This device solves the problem of difficult-to-heal injection holes and the risk of infection. Attached Figure Description

Detailed Implementation

[0035] Example 1

[0036] like Figures 1-15 As shown, a device for treating blockages in tree injection holes includes a core rod 2 fitted inside the cavity of a syringe 1, with its upper end extending a distance beyond the upper handle 101 of the syringe 1. A stopper 3 is fitted inside the syringe 1 and rests against the lower end of the syringe 1. The stopper 3 has a through hole in its center. The lower ends of both the syringe 1 and the stopper 3 are conical surfaces with multiple evenly distributed contraction slits. A tube clamp 4 is provided in the middle of the conical surface at the lower end of the syringe 1. First rollers 5 are symmetrically arranged on both sides of the syringe 1. A belt 6 passes over the upper edge of the first rollers 5, with one end connected to the tube clamp 4 and the other end connected to one end of the handle 101. Push rods 7 are symmetrically arranged on both sides of the core rod 2 and are located above the connection point between the first rollers 5 and the end of the belt 6. A healing agent 8 is placed inside the cavity of the syringe 1 and the stopper 3.

[0037] In the preferred embodiment, the lower end of the syringe 1 is evenly provided with multiple first contraction slits 102, and both ends extend to the starting and ending points of the conical surface, respectively. The first roller 5 is rotatably connected to the handle 101 through the first wheel frame 501. A through hole 103 is provided between the connection point of the first roller 5 on the handle 101 and the end of the belt 6. The lower end of the push rod 7 passes through the through hole 103 and abuts against the belt 6. The first contraction slits 102 extend to the maximum diameter of the syringe 1, so that the stopper 3 can be completely removed from the inside of the syringe 1.

[0038] In the preferred embodiment, the second contraction slit 301 at the lower end of the stopper 3 is in an open state in its natural state. After being squeezed and contracted, it abuts against the lower end of the inner wall of the syringe 1 and forms a conical surface after contraction. The outer diameter of the cylindrical part at the upper end of the stopper 3 is equal to the inner diameter of the syringe 1, and the total length of the stopper 3 is not greater than the length of the conical surface of the syringe 1.

[0039] The stopper 3 is made of wood.

[0040] The stopper 3 can open automatically without being squeezed, so that it can be easily removed from the syringe 1 and stuck inside the injection hole of the tree. Its outer diameter is closely fitted with the inner diameter of the syringe to prevent the healing agent 8 from leaking out from between the syringe 1 and the stopper 3. The wood material facilitates the healing of the injection hole.

[0041] In the preferred embodiment, the upper end of the core rod 2 is provided with a push plate 201, and the lower end is provided with an isolation plug 202. The isolation plug 202 is a plurality of conical surfaces that are stacked on top of each other, and its maximum outer diameter is equal to the inner diameter of the syringe 1. This ensures the sealing of the inside of the syringe 1 and facilitates the dispensing of the medicine.

[0042] In the preferred embodiment, the sum of the lengths of the core rod 2 and the isolation plug 202 is greater than the length of the cylindrical tube above the conical surface of the syringe 1. This allows the core rod 2 to push the plug tube 3 out of the syringe 1.

[0043] In the preferred embodiment, the clamp 4 consists of two semicircular rings 401, with two elastic elements 402 symmetrically arranged inside. One end of the elastic element 402 is connected to one end of one semicircular ring 401, and the other end is connected to one end of the other semicircular ring 401. The elastic element 402 drives the clamp 4 to press against the tapered surface at the lower end of the syringe 1. This allows the clamp 4 to change its inner diameter when moving upward, facilitating the loosening of the first contraction joint 102.

[0044] In the preferred embodiment, ear plates 403 are provided on both sides of the pipe clamp 4, and one end of the belt 6 is connected to the pipe clamp 4 through the ear plates 403.

[0045] In the preferred embodiment, a second roller 701 is provided at the lower end of the push rod 7, and the second roller 701 is rotatably connected to the push rod 7 through a second wheel frame 702. This results in rolling friction between the push rod 7 and the belt 6, which requires less effort.

[0046] In the preferred embodiment, the length of both ends of the handle 101 is greater than that of the push plate 201. This provides space for finger gripping, making it convenient for workers to grip the handle 101 and the push plate 201 with one hand.

[0047] In the preferred embodiment, the lower end of the syringe 1 is also provided with an inclined surface 104 to facilitate insertion of the lower end of the syringe 1 into the injection port.

[0048] During application, the clamp 4 in the middle of the conical surface at the lower end of the syringe 1 drives the second contraction slit 301 of the stopper 3 to compress and contract, so that the conical surface abuts against the lower conical surface of the inner wall of the syringe 1. The core rod 2 pushes the healing agent 8 to flow out through the internal cavity of the syringe 1 and the stopper 3 and inject it into the tree injection hole for disinfection and sterilization. The core rod 2 continues to be pushed so that its lower end abuts against the upper end of the stopper 3. At the same time, the push rod 7 presses down the belt 6, drives the clamp 4 to move upward, the first contraction slit 102 opens, the stopper 3 pushes out of the syringe 1, and the second contraction slit 301 at the lower end of the stopper 3 opens, so that the stopper 3 is stuck in the tree injection hole.

[0049] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
