Technical Field

[0001] This utility model relates to the field of trunk-boring pest control technology, and in particular to a trunk injection device for forest tree trunk-boring pests. Background Technology

[0002] Tree borers are a type of pest that, in their larval or adult form, bore into the interior of tree branches and trunks, damaging the phloem and xylem, cutting off the flow of nutrients and water, leading to tree weakness or even death. Tree borers tend to attack trees that are weak or have poor resistance, thus accelerating their death.

[0003] To control borers, pesticides can be injected into the branches and trunks of trees. The pesticides are then transported throughout the entire tree via transpiration or the tree's transport system, thus controlling the borers. This process can also replenish nutrients or regulate the growth of the trees.

[0004] Generally, medicine is injected into the branches and trunks of trees using a syringe. However, the syringe has a limited capacity and requires frequent climbing up and down. When climbing or turning, the needle of the syringe is easily damaged by collision with the trees or may injure the user. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1:

[0022] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a trunk injection device for wood borers, including an injection cylinder 1, a needle 2 threadedly connected to the injection cylinder 1, and a protective component 3 threadedly connected to the injection cylinder 1. The protective component 3 includes a protective sleeve 301, which is threadedly connected to the syringe 1. An extension sleeve 302 is slidably connected to the protective sleeve 301. A baffle 303 is fixedly connected to the inner wall of the protective sleeve 301. A first spring 304 is coaxially arranged on the protective sleeve 301. One end of the first spring 304 is fixedly connected to the extension sleeve 302, and the other end of the first spring 304 is fixedly connected to the baffle 303.

[0023] The inner wall of the protective sleeve 301 is provided with a sliding groove 305, and the outer wall of the extension sleeve 302 is fixedly connected with a slider 306, which slides in cooperation with the sliding groove 305.

[0024] The protective sleeve 301 is connected to the auxiliary component 4; The auxiliary component 4 includes a support base 401, a pressing rod 402 slidably connected to the support base 401, a positioning groove 403 formed in the pressing rod 402, the protective sleeve 301 and the extension sleeve 302, the pressing rod 402 slidably engaging with the positioning groove 403, a base plate 404 fixedly connected to the pressing rod 402, a second spring 405 fixedly connected to the base plate 404, the second spring 405 fixedly connected to the support base 401, and the second spring 405 and the pressing rod 402 being coaxially arranged.

[0025] The press lever 402 is fishhook shaped. Example 2:

[0026] Reference Figures 1-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the syringe 1 is fixedly connected to the support sleeve 5, the support sleeve 5 is fixedly connected to the expansion sleeve 6, the syringe 1 and the expansion sleeve 6 are connected, the expansion sleeve 6 is connected to the liquid inlet pipe 7, and the liquid inlet pipe 7 is threadedly connected to the sealing cap 8.

[0027] The extension cylinder 6 is threaded with a screw 9. One end of the screw 9 is fixedly connected to a handle 10, and the other end of the screw 9 is fixedly connected to a push plate 11. The push plate 11 is fitted with a rubber sleeve 12.

[0028] When in use, the sealing cap 8 is removed from the liquid inlet pipe 7 by rotating it, and the liquid is added to the device through the liquid inlet pipe 7. After the liquid is added, the sealing cap 8 is reinstalled on the liquid inlet pipe 7.

[0029] When injecting the medicine, align the needle 2 with the hole drilled by the electric drill or pest drill on the branch, and then apply external force to the pressing rod 402, causing the pressing rod 402 to slide on the support base 401 according to the direction of the force, thereby separating the pressing rod 402 from the positioning groove 403. At this time, the second spring 405 is stretched and deformed. Then, the extension sleeve 302 is pressed against the branch and a pushing force is applied. The total length of the protective sleeve 301 and the extension sleeve 302 is shortened due to the pushing force, and the first spring 304 is compressed. When the device is separated from the branch, the first spring 304 drives the extension sleeve 302 to return to its original position, and the second spring 405 drives the pressing rod 402 to return to its original position.

[0030] Rotating the handle 10 causes the screw 9 to rotate. The screw 9 rotates due to its thread and drives the push plate 11 to move and squeeze the liquid medicine. The pressure generated by the rotation of the screw 9 on the liquid medicine is controllable, thereby avoiding the leakage of liquid medicine caused by uneven manual injection force.

[0031] The expansion tube 6 increases the storage capacity of the medicine, reducing the number of times one needs to climb.

[0032] When climbing or turning is required, the protective sleeve 301 and the extension sleeve 302 cooperate to cover the needle 2 in the non-working state, thereby providing protection for the needle 2. The pressing rod 402 is inserted into the positioning groove 403 to prevent the total length of the protective sleeve 301 and the extension sleeve 302 from changing.

[0033] The remaining structure is the same as that in Example 1.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
