Description

Technical Field

[0001] The present invention relates to the technical field of biological control, and in particular to a device for controlling red imported fire ants. Background Art

[0002] The red imported fire ant (RIFA) is a highly aggressive invasive species. Its nests are complex and can reach depths of tens of centimeters or more underground, containing multiple interconnected passages and egg-laying chambers. The spread of RIFA not only disrupts ecological balance but also poses a serious threat to crops, public facilities, and human health. Therefore, effective control of RIFA nests is crucial for prevention and control.

[0003] Currently, chemical treatment methods for red imported fire ant nests are widely used. The core of these methods is to precisely inject a anticide solution deep into the nest structure to completely kill the queen ant and the entire colony. In existing technologies, commonly used treatment devices typically use a rotating drill bit structure: the drill bit is driven to rotate and drill into the ant nest, while the drug solution is transported deep into the ant nest through the channel inside the drill bit. However, such devices have significant drawbacks in actual use:

[0004] On the one hand, the advancement of the drill bit not only relies on the cutting force generated by its rotation, but also relies on the staff to hold the entire red fire ant control device and apply pressure to advance it. When encountering obstacles such as hard soil, dense structures in anthills, or stones, it becomes even more laborious. Due to the large depth of anthills (usually needing to drill 20-50cm underground), manual continuous pressure application is not only labor-intensive, but also easily leads to arm fatigue and low efficiency due to long-term operation. On the other hand, after the drill bit completes the injection of the liquid medicine, it needs to be extracted from the anthill. The existing device lacks an active extraction mechanism and still requires manual reverse force to pull it up. Especially when the drill bit is stuck with the soil or the anthill structure, the extraction process is even more laborious. It may even cause the drill bit to deform or the anthill structure to be damaged due to forced pulling, affecting the uniform diffusion of the liquid medicine in the hole and reducing the control effect.

[0005] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the Invention

[0006] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a device for controlling red imported fire ants, which is designed to automatically propel a drill bit downward into an anthill.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] An apparatus for controlling red imported fire ants, comprising an enclosure structure, an outer shaft, an inner tube, a top seat, a tripod connected to the bottom of the top seat, and a bearing seat provided on the top seat. The outer shaft is disposed in the bearing seat and has an axially through hole with a polygonal cross-section. The inner tube is adaptively inserted into the axially through hole and extends downward to connect a drill bit. The top of the inner tube extends out of the outer shaft and is connected to a rotary joint. An electric push rod and a drill bit driving device for driving the outer shaft to rotate are provided on the top seat. The output end of the electric push rod is connected to the rotary joint through a transmission block. The rotary joint is connected to a medicine supply assembly through a conduit. The drill bit is provided with liquid spraying holes. The medicine supply assembly pumps ant-killing liquid medicine, so that the ant-killing liquid medicine sequentially passes through the conduit, the rotary joint, the inner tube and the drill bit and then sprays out from the liquid spraying holes. The enclosure structure is used to enclose an ant nest to form a space with an upward opening, and the drill bit can enter or leave the space from the opening.

[0009] As a further improvement of the above technical solution, the axially through hole is a square through hole, and the cross-section of the inner tube is square.

[0010] As a further improvement of the above technical solution, the drill bit driving device includes a motor provided on the top seat, a first gear provided on the output end of the motor, and a second gear sleeved on the outer shaft. The first gear and the second gear are meshed and driven.

[0011] As a further improvement of the above technical solution, a first switch for controlling the operation of the electric push rod and a second switch for controlling the operation of the drill bit driving device are provided on the top seat. The first switch, the second switch, the electric push rod and the motor are all connected to a control panel, and a power supply port is provided on the control panel.

[0012] As a further improvement of the above technical solution, the enclosure structure includes a plurality of enclosure panel assemblies. Each enclosure panel assembly includes a base, a support rod, a cross beam and a shielding cloth. The lower end of the support rod is hinged to the base. The cross beam is horizontally disposed at the upper end of the support rod. The cross beam and the support rod are fixedly connected. The upper side edge of the shielding cloth is fixedly connected to the cross beam, and the lower side edge of the shielding cloth is fixedly connected to the base. All the bases form a closed loop. In two adjacent enclosure panel assemblies, two adjacent shielding cloths are connected by magic tapes.

[0013] As a further improvement of the above technical solution, in each enclosure panel assembly, two support rods are provided. The lower ends of the two support rods are respectively hinged to the base. The cross beam is fixedly connected to the upper ends of the two support rods. A plurality of first straps are provided on the shielding cloth, and the first straps are used for binding to the support rods.

[0014] As a further improvement of the above technical solution, a plurality of nails for driving into the soil are provided on the bottom surface of the base.

[0015] As a further improvement of the above technical solution, two limit sleeves are provided on the base, and an elastic retaining piece is provided between two adjacent bases. The left and right sides of the elastic retaining piece extend out limit protrusions, and the limit protrusions on the left and right sides of the limit protrusions are respectively inserted into two adjacent limit sleeves on the corresponding two bases.

[0016] As a further improvement of the above technical solution, a blade is provided on each base, and the blade is arranged in the closed loop and is used for inserting into the soil.

[0017] As a further improvement of the above technical solution, a hand-held ear is provided on the top seat.

[0018] Advantages of the present invention: Compared with the prior art that requires manual continuous pressure to push the drill bit and needs to pull it back in the opposite direction when withdrawing, with high labor intensity and low efficiency, the red imported fire ant control device provided by the present invention provides the active power for axial advancement and withdrawal through an electric push rod, replacing manual force application, and significantly reducing the operation burden of the staff; at the same time, the stable thrust of the electric push rod and the rotary cutting force of the drill bit act together to cope with obstacles such as hard soil, dense ant nest structures or stones, improving the drilling efficiency. The enclosure structure forms a space with an upward opening by enclosing the ant nest, which can reduce the diffusion and loss of the liquid medicine outside the ant nest, concentrate the liquid medicine in the inner channels and the egg-laying chamber of the nest, improve the utilization rate of the liquid medicine, and at the same time reduce the pollution risk to the surrounding environment (such as soil, crops).

[0019] In addition, when withdrawing the drill bit of the existing red imported fire ant control device, it needs to be manually lifted, which is easy to cause the drill bit to deform or the ant nest structure to be damaged (such as the collapse of the inner channels in the nest) due to jamming, affecting the diffusion of the liquid medicine. The red imported fire ant control device provided by the present invention actively controls the withdrawal process through an electric push rod, can apply a uniform pulling force, and reduce the risk of jamming; even if encountering slight jamming, it can be relieved by adjusting the pulling speed of the electric push rod or cooperating with the micro-rotation of the drill bit (assisted by the driving device), avoiding structural damage caused by forced lifting, ensuring the uniform diffusion of the liquid medicine in the ant nest, and improving the ant control effect.

[0028] The present invention provides a device for controlling red imported fire ants. To make the objectives, technical solutions and effects of the present invention clearer and more definite, the following further elaborates on the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention

[0029] Please refer to Figures 1 to 7 , the present invention provides a device for controlling red imported fire ants, including an enclosure structure, an outer shaft 1, an inner tube 2, a top seat 3, a tripod 33 (such as a tripod 33) connected to the bottom of the top seat 3, and a bearing seat 31 provided on the top seat 3. The outer shaft 1 is disposed in the bearing seat 31 and is provided with an axial through hole 11 having a polygonal cross-section. The inner tube 2 is adapted to be inserted into the axial through hole 11 and extends downward to connect a drill bit 6. The top of the inner tube 2 extends out of the outer shaft 1 and is connected to a rotary joint 7. The top seat 3 is provided with an electric push rod 4 and a drill bit driving device for driving the outer shaft 1 to rotate. The output end of the electric push rod 4 is connected to the rotary joint 7 through a transmission block 41. The rotary joint 7 is connected to a medicine supply assembly through a conduit. The drill bit 6 is provided with a liquid spraying hole 61. The medicine supply assembly pumps ant-killing liquid medicine, so that the ant-killing liquid medicine sequentially passes through the conduit, the rotary joint 7, the inner tube 2 and the drill bit 6 and then sprays out from the liquid spraying hole 61. The enclosure structure is used to enclose an ant nest to form an upward-opening space 90, and the drill bit 6 can enter or leave the space 90 from the opening

[0030] During operation, cover the enclosure structure above the red imported fire ant nest. Enclose the ant nest with the enclosure structure to form a closed or semi-closed space with an upward opening, ensuring that the subsequent drilling and medicine injection processes are concentrated in the ant nest area. Start the drill drive device to drive the outer shaft 1 to rotate; since the axial through hole 11 of the outer shaft 1 is polygonal (such as hexagonal, quadrilateral), the inner tube 2 is circumferentially fixed to the outer shaft 1 through a matching polygonal cross-section. Therefore, when the outer shaft 1 rotates, it can synchronously drive the inner tube 2 and the drill bit 6 to rotate, providing the rotational power for cutting the soil / ant nest structure. At the same time, the electric push rod 4 is started and extended, and its output end pushes the rotary joint 7 downward through the transmission block 41. The rotary joint 7 drives the inner tube 2 to slide downward along the axial through hole 11 of the outer shaft 1, thereby continuously pressing the drill bit 6 into the deep layer of the ant nest (such as 20 - 50 cm). During this process, the rotational cutting and the axial thrust of the electric push rod 4 act together to achieve the efficient drilling of the drill bit 6. When the drill bit 6 reaches the target depth (such as the egg-laying chamber or the main passage of the ant nest), the medicine supply component (such as a liquid medicine pump) is started, and the ant-killing liquid medicine is transported to the inside of the drill bit 6 through the catheter, the rotary joint 7, and the inner tube 2, and is sprayed into the deep structure of the ant nest through the liquid spraying holes 61 on the drill bit 6, completing the precise injection of the liquid medicine. After the medicine injection is completed, the electric push rod 4 contracts, pulls the rotary joint 7 upward through the transmission block 41, and the rotary joint 7 drives the inner tube 2 and the drill bit 6 to slide upward along the axial through hole 11 of the outer shaft 1, actively pulling the drill bit 6 out of the ant nest to avoid manual lifting.

[0031] Compared with the prior art that requires manual continuous pressure to push the drill bit 6 forward and reverse lifting when pulling it out, with high labor intensity and low efficiency, the red imported fire ant control device provided by the present invention provides the active power for axial propulsion and extraction through the electric push rod 4, replacing manual force application, significantly reducing the operation burden of the staff; at the same time, the stable thrust of the electric push rod 4 and the rotational cutting force of the drill bit 6 act together to cope with obstacles such as hard soil, dense ant nest structures or stones, improving the drilling efficiency. The enclosure structure forms a space with an upward opening by enclosing the ant nest, which can reduce the diffusion and loss of the liquid medicine outside the ant nest, make the liquid medicine concentrate in the inner channels and the egg-laying chamber of the nest, improve the utilization rate of the liquid medicine, and at the same time reduce the pollution risk to the surrounding environment (such as soil, crops).

[0032] In addition, when pulling out the drill bit 6 of the existing red imported fire ant control device, manual lifting is required, which is likely to cause the deformation of the drill bit 6 or the damage of the ant nest structure (such as the collapse of the inner channels of the nest) due to jamming, affecting the diffusion of the liquid medicine. The red imported fire ant control device provided by the present invention actively controls the extraction process through the electric push rod 4, can apply a uniform pulling force, reducing the risk of jamming; even in case of slight jamming, it can be relieved by adjusting the pulling speed of the electric push rod 4 or cooperating with the micro-rotation of the drill bit 6 (assisted by the drive device), avoiding structural damage caused by forced lifting, ensuring the uniform diffusion of the liquid medicine in the ant nest, and improving the ant-killing effect.

[0033] In this embodiment, the axial through-hole 11 is a square through-hole, and the cross-section of the inner tube 2 is square. The four sides of the square are symmetrically distributed, and the torque generated by the rotation of the outer shaft 1 can be evenly transmitted to the inner tube 2 and the drill bit 6. When drilling in hard soil or a dense structure of an ant nest, the four sides are synchronously stressed, avoiding sliding or dislocation caused by local stress concentration, ensuring that the drill bit 6 obtains stable cutting power and improving the drilling efficiency. At the same time, compared with a circular through-hole that can only transmit torque through a keyway or spline, which has a complex structure and is prone to wear, the square cross-section does not require an additional key connection, simplifies the structure, and reduces the transmission loss.

[0034] When the electric push rod 4 drives the inner tube 2 to axially slide (advance or withdraw) along the outer shaft 1, the frictional forces on each contact surface are balanced, avoiding jamming or deflection caused by excessive unilateral friction. For example, during the drilling process, when the inner tube 2 slides downward, the four sides are synchronously in contact with the through-hole of the outer shaft 1, ensuring that the drill bit 6 advances vertically downward and avoiding jamming of the drill bit 6 with the soil / ant nest structure due to deflection. When withdrawing, the smoothness of the upward sliding of the inner tube 2 can also reduce the scraping of the drill bit 6 against the hole wall, further reducing the withdrawal resistance and improving the operation fluency.

[0035] Specifically, the drill bit driving device includes a motor 81 arranged on the top seat 3, a first gear 82 arranged on the output end of the motor 81, and a second gear 83 sleeved on the outer shaft 1. The first gear 82 and the second gear 83 are in meshing transmission. When the motor 81 starts to output torque, the first gear 82 on the output shaft of the motor 81 rotates synchronously with the motor 81. Since the first gear 82 meshes with the second gear 83 sleeved on the outer shaft 1, the rotation of the first gear 82 drives the second gear 83 to rotate through tooth surface contact, thereby transmitting the torque of the motor 81 to the outer shaft 1. The second gear 83 is fixedly sleeved on the outer shaft 1 (such as through key connection or interference fit), so the rotation of the second gear 83 directly drives the outer shaft 1 to rotate around its axis. An axial square through-hole 11 is formed inside the outer shaft 1, and the inner tube 2 is inserted into the through-hole with a square cross-section for adaptation. When the outer shaft 1 rotates, the inner tube 2 is synchronously driven to rotate through the circumferential limiting action (contact of the four sides) of the square cross-section; the drill bit 6 connected to the lower end of the inner tube 2 rotates accordingly, generating the rotational power for cutting the soil or the ant nest structure. While the drill bit 6 is rotating, the electric push rod 4 extends synchronously, and through the transmission block 41, it pushes the rotary joint 7 and the inner tube 2 to axially slide downward along the outer shaft 1, so that the rotating drill bit 6 continuously presses into the deep layer of the ant nest.

[0036] Preferably, a first switch 52 for controlling the operation of the electric push rod 4 and a second switch for controlling the operation of the drill driving device are provided on the top seat 3. The first switch 52, the second switch, the electric push rod 4 and the motor 81 are all connected to the control panel 51, and a power supply port is provided on the control panel 51. The power supply port (such as a DC interface, a USB-C interface or a battery compartment) is connected to an external power supply (such as a lithium battery, a mobile power supply or a mains adapter). The power supply does not need to be arranged on the top seat 3, which can reduce the overall weight. Through the independent control of the first switch 52 and the second switch by the staff, the staff only needs to use one hand or simply press to start / stop the electric push rod 4 (control the advancement / withdrawal) and the motor 81 (control the rotation of the drill bit 6), replacing the traditional manual force application operation mode and greatly reducing the labor intensity. At the same time, the telescopic speed of the electric push rod 4 can be preset through the control panel 51 (such as uniform advancement), avoiding the force fluctuation during manual pressure application and further improving the operation comfort.

[0037] The medicament supply component specifically includes a medicament barrel, an infusion pump and a catheter. After the ant-killing medicament is diluted in the medicament barrel, the infusion pump pumps the liquid medicine to the catheter.

[0038] Specifically, please refer to Figures 4 - 7 , the enclosure structure includes a plurality of enclosure panel components 9, and the number of components can be flexibly adjusted according to the size of the ant nest. Each enclosure panel component 9 includes a base 91, a support rod 92, a cross beam 94 and a shielding cloth 93. The lower end of the support rod 92 is hinged to the base 91, the cross beam 94 is horizontally arranged at the upper end of the support rod 92, the cross beam 94 and the support rod 92 are fixedly connected, the upper side edge of the shielding cloth 93 is fixedly connected to the cross beam 94, and the lower side edge of the shielding cloth 93 is fixedly connected to the base 91; all the bases 91 form a closed loop, and in two adjacent enclosure panel components 9, two adjacent shielding cloths 93 are connected by Velcro.

[0039] The hinge design of the support rod 92 and the base 91 enables the support rod 92 to rotate around the base 91 to adjust the angle (such as tilting forward / backward), so as to adapt to different terrains (such as uneven ground, slopes or protrusions around the ant nest). By adjusting the angles of the support rods 92 of each enclosure panel component 9, the shielding cloth 93 can be closely attached to the ground, reducing or even eliminating the gaps caused by uneven ground for traditional rigid enclosure panels (such as leakage gaps at the protrusions of stones and grass roots), ensuring that the ant nest is completely enclosed, preventing red imported fire ants from escaping through the gaps and attacking the operators after being disturbed, and at the same time avoiding the leakage of liquid medicine from the gaps and polluting the environment.

[0040] The adjacent shielding cloth 93 is connected by Velcro, featuring the characteristics of being instantly attachable and detachable. The staff can quickly unfold the enclosure assembly 9 (by rotating the support rod 92 to the upright state), lay the base 91 along the edge of the ant nest to form a closed loop, and then paste and close the adjacent shielding cloth 93 through Velcro to complete the construction of the enclosed space. After the treatment, only by tearing the Velcro and folding the support rod 92 can it be quickly stored, significantly shortening the device deployment and evacuation time. It is especially suitable for the continuous treatment of multiple ant nests in the wild, remarkably improving the operation efficiency.

[0041] In each of the enclosure assemblies 9, two support rods 92 are provided. The lower ends of the two support rods 92 are respectively hinged to the base 91, and the cross beam 94 is fixedly connected to the upper ends of the two support rods 92 to form a rigid frame with stronger lateral bending moment resistance. When the drill bit 6 vibrates during drilling (such as when contacting hard soil or rocks), or when the red imported fire ants are stimulated and hit the shielding cloth 93, the double support rods 92 can be synchronously stressed through the two side fulcrums, avoiding the inclination or toppling of the single support rod 92 caused by unilateral stress, ensuring the upright stability of the enclosure assembly 9 and maintaining the sealing of the enclosed space of the ant nest.

[0042] A plurality of first straps 933 are provided on the shielding cloth 93, and the first straps 933 are used to be tied to the support rod 92. The two support rods 92 serve as the left and right support points of the shielding cloth 93, and the straps are respectively fixed to the middle or upper part of the two side support rods 92, so that the shielding cloth 93 is evenly straightened along the height direction of the support rod 92 (from the base 91 to the cross beam 94), avoiding gaps caused by unilateral slack, ensuring that the ant nest is completely wrapped around, and preventing the escape of red imported fire ants or the leakage of liquid medicine. It can be understood that the straps are flexible fixing methods (such as nylon fastener tapes, elastic ropes), and the tension can be adjusted according to the angle of the support rod 92: when the support rod 92 is tilted to adapt to the terrain, by adjusting the binding position of the strap (such as moving the strap up or down), the shielding cloth 93 can be re-tightened to keep it in close contact with the ground / cross beam 94, further improving the enclosure effect.

[0043] Furthermore, a plurality of nails 911 for driving into the soil are provided on the bottom surface of the base 91. The sharp ends of the nails 911 can be driven into the soil (or the soft soil around the ant nest), tightly connecting the base 91 to the ground.

[0044] Further, two limiting sleeves 952 are provided on the base 91, and an elastic retaining piece 951 is provided between two adjacent bases 91. The left and right sides of the elastic retaining piece 951 extend out with limiting protrusions, and the limiting protrusions on the left and right sides of the limiting protrusions are respectively inserted into two adjacent limiting sleeves 952 on the corresponding two bases 91, so that the installation is very convenient. In addition, the lower side of the elastic retaining piece 951 can be lower than the bottom surface of the base 91, so that the lower side of the elastic retaining piece 951 can be inserted into the soil to improve the sealing performance between adjacent bases 91.

[0045] The contact between the traditional flat base 91 and the ground only relies on self-weight extrusion, and it is easy to generate gaps (such as 2 - 3 mm) due to the uneven ground. The red imported fire ants can drill out from the gaps or the liquid medicine can leak; for this reason, a blade 912 is provided on each base 91, and the blade 912 is arranged in the closed loop, and the blade 912 is used to insert into the soil. The thin blade structure of the blade 912 can be embedded into the tiny pores of the soil to fill the gap between the base 91 and the ground (even if there is a 1 - 2 mm undulation on the ground), forming an almost seamless sealing layer, completely blocking the escape path of the ant colony, and at the same time preventing the liquid medicine from penetrating along the edge of the base 91 to the peripheral soil, ensuring that the liquid medicine acts concentratedly inside the ant nest.

[0046] In some embodiments, the length of the shielding cloth 93 in the left - right direction is greater than the length of the base 91, and the vertical center line of the shielding cloth 93 is located at the vertical center line of the base 91. This structure is simple and convenient to set. Through the setting of this structure, the shielding cloth 93 and the base 91 can be centered, and in addition, it is convenient to connect adjacent shielding cloths 93.

[0047] In some embodiments, a hook surface 931 of a magic tape is provided on the front side of the left side of each shielding cloth 93, and a fluff surface 932 of the magic tape is provided on the back side of the right side of each shielding cloth 93. The difference between the length of the shielding cloth 93 in the left - right direction and the length of the base 91 in the left - right direction is a, and the widths of the hook surface 931 and the fluff surface 932 are both greater than a / 2. This structure is simple and convenient to set. Through the setting of this structure, the adjacent two shielding cloths 93 can be fixedly connected through the magic tape. For example, among two adjacent shielding cloths 93 on the left and right, the fluff surface 932 on the right side of the left shielding cloth 93 is attached to the hook surface 931 on the left side of the right shielding cloth 93.

[0048] In actual use, the front side of the shielding cloth 93 refers to the surface of the shielding cloth 93 facing away from the above - mentioned closed loop, and the back side of the shielding cloth 93 refers to the surface of the shielding cloth 93 facing the above - mentioned closed loop.

[0049] In some embodiments, a second strap 934 is provided on the shielding cloth 93, and the cross beam 94 and the shielding cloth 93 are fixedly connected through the second strap 934. Through the arrangement of the second strap 934, an operator can adjust the tightening degree according to actual requirements.

[0050] Preferably, a hand-held ear 32 is provided on the top seat 3. It is convenient for the staff to grasp the hand-held ear 32 and transfer the position of the red imported fire ant control device.
