Technical Field
[0001] This utility model relates to the technical field of red imported fire ant control devices, and more specifically to a red imported fire ant bait delivery device based on a tree trunk. Background Technology
[0002] Red imported fire ants (Solenopsis invicta), native to South America, are highly aggressive. In urban green spaces, they typically nest at the base of roadside and ornamental trees, frequently climbing the trunks to the canopy to forage. This not only exacerbates their spread but also seriously threatens the safety of pedestrians and nearby residents, easily causing bites and allergic reactions, posing a significant challenge to urban public safety. Among the many control measures for red imported fire ants, chemical control has become a key means of controlling their spread due to its high efficiency and rapid effectiveness. Chemical control methods mainly include baiting, powdering, and drenching the nest. Among these, baiting is the most common and effective method, saving time, labor, and effort. Baiting typically involves scattering bait in a dotted or circular pattern around the nest, utilizing the worker ants' tendency to feed each other to transfer the active ingredients in the bait throughout the nest, ultimately reaching the queen and achieving nest extermination.
[0003] For controlling red imported fire ants on tree trunks, the bait-trapping method faces significant challenges. Directly scattering bait on the trunk not only results in substantial waste and reduced control efficiency, but also causes long-term negative impacts on soil microorganisms and the ecosystem from fallen bait. Furthermore, due to the wide distribution range of the bait, it is easily ingested by non-target organisms, especially those with similar feeding habits to red imported fire ants. Additionally, the bait on the trunk is easily washed away by rain, significantly diminishing its palatability and odor, thus severely impacting its effectiveness in attracting red imported fire ants and reducing control efficiency. Some existing traps can be installed on tree trunks, with multiple evenly spaced attractant holes on the side wall of the baited trap to lure the target ants in. A rain cap is installed on top of the trap to prevent rainwater from entering. While the rain cap provides some protection, it does not offer complete protection; under wind conditions, rainwater can still easily enter the trap and wet the bait.
[0004] Therefore, there is an urgent need to develop a more efficient, interference-resistant, and easy-to-operate tool for controlling red imported fire ants. Utility Model Content
[0005] In view of this, the present invention aims to provide a tree trunk-based red imported fire ant bait delivery device to at least partially solve the problems in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A clamping assembly, one end of which is used to clamp onto a tree trunk;
[0008] A support frame is fixed to the other end of the clamping assembly;
[0009] The bait box includes a box body and a box lid. The box body is detachably mounted on the support frame, and a box lid placement entrance is provided at one end near the clamping assembly. The box lid is fitted into the inner cavity of the box body through the box lid placement entrance, and multiple red fire ant entrances communicating with the inner cavity of the box body are provided on the lid surface. The bait is placed in the inner cavity of the box body.
[0010] The beneficial effects that this invention can achieve are as follows: This device is clamped to the tree trunk, and the lid of the bait box is placed with the entrance facing the tree trunk. This not only allows the red imported fire ants on the tree trunk to enter the box smoothly, enhancing the attraction effect, but also reduces the amount of rainwater entering the box by utilizing the tree trunk as a shield. In addition, the lid is placed inside the box cavity, which can prevent the bait from falling out, enhance the effect of the bait's aroma, and prevent the lid itself from getting wet by rainwater. This also prevents rainwater from entering the box through the red imported fire ant entrance and wetting the bait, thus preventing it from affecting the attraction effect.
[0011] Furthermore, the clamping assembly includes a mounting base, multiple grippers, and locking bolts. The mounting base is fixed to one end of the support frame, and the multiple grippers are circumferentially spaced at the end of the mounting base away from the support frame to clamp onto the tree trunk. Each gripper is hinged to the mounting base along the direction from the center of the mounting base to its periphery to close or open, and can be fastened by locking bolts.
[0012] The beneficial effects that can be achieved by adopting the previous technical solution are: the grippers can be adjusted to hold the tree trunks of different thicknesses.
[0013] Furthermore, there is a gap between the box and the mounting base for the passage of red imported fire ants.
[0014] The beneficial effect of adopting the above technical solution is to prevent the entrance of red imported fire ants from being blocked by the mounting base after the box is installed.
[0015] Furthermore, a male plug is fixed to the middle of the outer side wall of the box, and a female plug that engages with the male plug is fixed on the support frame.
[0016] The beneficial effects of adopting the above technical solution are: easy assembly and disassembly of the bait box, and convenient cleaning and bait replacement.
[0017] Furthermore, it also includes a plurality of connecting components for connecting the lid and the box body. The connecting components are evenly spaced along the circumferential direction of the lid and one end is fixed to the lid, while the other end is detachably connected to the side wall of the box body corresponding to the side where the lid is placed.
[0018] The beneficial effects that can be achieved by adopting the above technical solution are: the lid is placed inside the box cavity to prevent the bait from falling out, and it reduces contact with rainwater, allowing the rainwater to be carried into the box.
[0019] Furthermore, the connecting assembly includes a first side plate, a U-shaped plate, and a second side plate. The first side plate is arranged along the axial direction of the box cover inlet and one end is fixed to the box cover. The opening of the U-shaped plate is arranged facing the box cover inlet and one end is fixed to the other end of the first side plate. The second side plate is arranged parallel to the first side plate and one end is fixed to the other end of the U-shaped plate. The other end forms a clamping cavity with the first side plate. The side wall of the box body corresponding to the box cover inlet can be clamped in the clamping cavity.
[0020] The beneficial effects that can be achieved by adopting the technical solution in the previous step are: convenient disassembly and assembly of the box lid.
[0021] Furthermore, the end of the second side plate away from the U-shaped plate is inclined in a direction away from the first side plate.
[0022] The beneficial effects of adopting the previous technical solution are: it makes the clamping cavity formed by the second side plate and the first side plate larger, which facilitates installation on the side wall of the box lid inlet.
[0023] Furthermore, the box body is a polygonal prism or a cylinder, and the box lid has the same shape as the inner cavity of the box.
[0024] The beneficial effects that can be achieved by adopting the above technical solution are: the lid can be smoothly slid into the inner cavity of the box, thereby blocking the bait and preventing the bait from falling out.
[0025] Furthermore, the box body is tilted upwards along the entry direction of the red imported fire ant.
[0026] The beneficial effects of adopting the previous technical solution are: the lid is tilted downwards at the entrance to prevent rainwater from entering the inner cavity of the box and wetting the bait.
[0027] Furthermore, the box is a transparent box.
[0028] The beneficial effects of adopting the above technical solution are: it allows for direct observation of bait feeding, thereby understanding the control effect of red imported fire ants.
[0029] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a red imported fire ant baiting device based on a tree trunk. It is installed on a tree trunk with the entrance of the bait box facing the side of the tree trunk. This not only allows the odor to be emitted in a directional manner, enabling the red imported fire ants on the tree trunk to enter the box smoothly and enhancing the attraction effect, but also reduces the amount of rainwater entering the box through the entrance of the lid by utilizing the tree trunk as a shield. In addition, the lid can prevent the bait from falling off, enhance the effect of the bait odor emission, and prevent the lid itself from getting wet by rainwater, thus preventing rainwater from entering the box through the entrance of the red imported fire ants and wetting the bait, and preventing it from affecting the attraction effect.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0039] Please see Figures 1-4 This utility model discloses a tree trunk-based red imported fire ant baiting device, comprising: a clamping component 1, a support frame 2, and a bait box 3. One end of the clamping component 1 is used to clamp onto the tree trunk; the support frame 2 is fixed to the other end of the clamping component 1; the bait box 3 includes a box body 31 and a box lid 32. The box body 31 is detachably mounted on the support frame 2, and a lid placement entrance is opened at the end near the clamping component 1. The box lid 32 is fitted into the inner cavity of the box body through the lid placement entrance, and its lid surface has multiple red imported fire ant entrances communicating with the inner cavity of the box body 31; the bait is placed in the inner cavity of the box body 31. In use, the box body 31 can be installed at any position on the top, bottom, or side wall of the support frame 2, but it must be ensured that the lid placement entrance faces the tree trunk. This allows the red imported fire ants on the tree trunk to smoothly enter the interior of the box body 31, enhancing the attraction effect. Moreover, the tree trunk can block rainwater from the lid placement entrance side, reducing the probability of rainwater entering the box body 31. Multiple red imported fire ant entrances are provided on the lid, allowing the bait's scent to escape while simultaneously preventing the bait from falling out. The lid is internally located within the box's cavity because rainwater tends to slide off smooth surfaces, but is less likely to fall off the porous lid. If the lid were external and in contact with the outside, rainwater would be more likely to cling to it, causing more rainwater to enter the box 31 through the red imported fire ant entrances, wetting the bait and affecting its attractant effect. The internal lid 32 avoids direct contact between the lid and rainwater, preventing rainwater from entering the box 31 through the lid 32.
[0040] In one specific embodiment, the clamping assembly 1 includes a mounting base 11, multiple grippers 12, and locking bolts 13. The mounting base 11 is fixed to one end of the support frame 2. The multiple grippers 12 are circumferentially spaced at the end of the mounting base 11 away from the support frame 2 to clamp onto the tree trunk. Each gripper 12 is hinged to the mounting base 11 along its center to its periphery to close or open, and can be secured by the locking bolts 13. The distance between the grippers can be adjusted by rotating the grippers 12 to clamp onto tree trunks of different sizes. The number of grippers 12 can be increased or decreased as needed, but is at least two. If there is an even number of grippers 12, the even number of grippers 12 are symmetrically distributed on both sides of the tree trunk; if there is an odd number of grippers 12, the grippers 12 on both sides of the tree trunk are staggered along the height direction of the tree trunk, that is, the gripper on one side of the tree trunk corresponds to the position between two adjacent grippers on the opposite side, in order to balance the clamping force on both sides and enhance stability.
[0041] In one specific embodiment, there is a gap between the box body 31 and the mounting base 11 for the passage of red imported fire ants. This gap can be in the vertical direction or in the horizontal direction. That is, after the box body 31 is installed, there is a horizontal gap between the entrance side of the box cover and the mounting base 11 to allow the red imported fire ants to pass through. Alternatively, the entrance side of the box cover can be arranged higher than the mounting base 11 to prevent the entrance of the red imported fire ants from being blocked by the mounting base 11 after the box body 31 is installed, so that the red imported fire ants cannot climb from the tree trunk into the box body 31.
[0042] In one specific embodiment, a male plug 41 is fixed to the middle of the outer wall of the box 31, and a female plug 42 that engages with the male plug 41 is fixed on the support frame 2. This facilitates the assembly and disassembly of the bait box 3, and makes it easy to clean and replace the bait. In one specific embodiment, the male plug 41 is a fixing post fixed to the outer wall of the box 31, and the female plug 42 is a slot formed on the support member, with the fixing post interference-fitted into the slot. In some other embodiments, the male plug 41 and the female plug 42 can be other connectors in the prior art that can achieve a secure snap-fit engagement.
[0043] In one specific embodiment, a plurality of connecting components 33 for connecting the lid 32 and the box body 31 are further included. The connecting components 33 are evenly spaced along the circumferential direction of the lid 32, with one end fixed to the lid 32 and the other end detachably connected to the side wall of the box body 31 corresponding to the side where the lid is placed. This facilitates the fixing of the lid 32.
[0044] In one specific embodiment, the connecting component 33 includes a first side plate 331, a U-shaped plate 332, and a second side plate 333. The first side plate 331 is arranged along the axial direction of the lid placement entrance and one end is fixed to the lid 32. The opening of the U-shaped plate 332 is arranged facing the lid placement entrance and one end is connected to the other end of the first side plate 331. The second side plate 333 is arranged parallel to the first side plate 331 and one end is fixed to the other end of the U-shaped plate 332. The other end forms a clamping cavity with the first side plate 331. The side wall of the box body 31 near the lid placement entrance can be clamped in the clamping cavity to facilitate the installation and removal of the lid.
[0045] In one specific embodiment, the end of the second side plate 333 away from the U-shaped plate 332 is inclined away from the first side plate 331, so that the clamping cavity formed by the second side plate 333 and the first side plate 331 has a larger opening, which makes it easier to clamp on the side wall of the box lid placement entrance.
[0046] In one specific embodiment, the box body 31 is a polygonal prism or cylinder, and the box cover 32 has the same shape as the inner cavity of the box body 31, so that the box cover 32 can smoothly and seal and slide in the inner cavity of the box body 31. This makes installation convenient and can completely block the bait, preventing the bait from falling from the gap between the box cover 32 and the inner wall of the box body 31 and polluting the soil around the tree trunk.
[0047] In one specific embodiment, the box body 31 is tilted upward along the entry direction of the red imported fire ant entrance, and the angle between it and the horizontal plane does not exceed 5°, so that the box lid of the box body 31 is slightly tilted downward, ensuring that the small particles of bait will not slide out of the red imported fire ant entrance and reducing the probability of rainwater falling into the box body 31. Even if a small amount of rainwater falls into the box lid entrance, it can slide out quickly and will not enter the inner cavity of the box body 31 and wet the bait.
[0048] In one specific embodiment, the box 31 is a transparent box, which allows for direct observation of the bait feeding situation, thereby understanding the baiting and killing effect of the red imported fire ants.
[0049] A method for controlling red imported fire ants includes the following steps:
[0050] Step 1, Prepare the bait:
[0051] According to the prevention and control needs, select appropriate bait, place the bait at the bottom of bait box 3, and then close the lid 2 to ensure that the bait does not fall out and that the red imported fire ants can enter and feed smoothly, so as to continuously attract red imported fire ants.
[0052] Step 2, Assemble the device:
[0053] Position the lid of bait box 3 so that the entrance faces the tree trunk, install bait box 3 on support frame 2, check that all parts are securely connected, and ensure that the device is ready for the next step.
[0054] Step 3, Fixing device:
[0055] Place or fix the assembled device in the target area, securing it 15cm from the base of the tree trunk. Ensure the device is firmly clamped to prevent slippage or displacement.
[0056] Step 4, Monitoring:
[0057] After the device is fixed in place, monitor it for a period of time to observe the feeding behavior of the bait.
[0058] Step 5, Clean up and reuse:
[0059] After use, clean all parts of the device, especially bait box 3, to ensure that there are no residual red imported fire ants or bait. After cleaning, the device can be used again. Replace the bait as needed and redeploy the device to a new control area.
[0060] By following the above steps, the control of red imported fire ants can be carried out efficiently, providing reliable support for the distribution survey and control of red imported fire ants.
[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments.
