Description

Technical Field

[0001] This utility model relates to the field of grain storage pest control technology, specifically a flying insect adhesive trap. Background Technology

[0002] The wheat moth and the Indian meal borer are global pests that damage stored grains, and are also significant grain pests in my country. Their main damaging stage is the larval stage, when the larvae bore into the grains, causing damage, with wheat, rice, and corn being the most severely affected. Currently, the main method for controlling the wheat moth and the Indian meal borer is phosphine fumigation. However, grain pests have developed widespread resistance to phosphine, and phosphine is a phase-out chemical used in grain storage. Therefore, there is an urgent need to find alternative methods for phosphine control.

[0003] Using insect traps to trap pests is an environmentally friendly and pollution-free method of pest control. Trapping directly attracts and kills pests, and it is a simple, convenient, practical, and economical device. Existing insect traps include the "Online Monitoring Device for Flying Insects" disclosed in Chinese Patent CN111903641A. This device includes a trapping apparatus and an outer cylinder. The trapping apparatus includes a tapered adhesive plate (smaller at the top, larger at the bottom) inside the outer cylinder. The outer conical surface of the adhesive plate is used to trap insects. The outer cylinder has an insect entrance for insects to fly in from the outside. The trapping apparatus also includes a hanging structure connected to the outer cylinder. The hanging structure includes hooks and at least three pins connected to the lower end of the hooks via hanging ropes. The outer cylinder has pin holes for the corresponding pins to pass through radially. One end of the pin on the outside of the outer cylinder is connected to the hanging rope, and the other end of the pin on the inside of the outer cylinder presses against the upper surface of the top cover.

[0004] In use, flying insects are attracted by the trapping device, entering the outer cylinder through the insect inlet and then being stuck to the outer conical surface of the adhesive plate. The adhesive plate's design, wider at the bottom than the top, ensures a sufficiently large trapping area for effective insect capture. However, existing traps have several drawbacks: with prolonged use, the adhesive plate becomes covered in flying insects, affecting the trapping of subsequent insects. Replacing the adhesive plate requires removing the entire device, pulling out the pin, removing the top cover, and then retrieving the adhesive plate from the top. This process is complex, and the small opening at the top of the trap makes removing the adhesive plate inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a flying insect adhesive trap, which aims to solve the problem that in the prior art, when it is necessary to replace the adhesive plate, it is necessary to remove the trapping device, pull out the pin, remove the top cover, and then take out the adhesive plate from the top of the trap for replacement.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0025] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0026] like Figure 1-5 As shown, a flying insect adhesive trap includes an outer tube 1, an adhesive plate 5 inside the outer tube 1, a snap-fit ​​edge 6 at the bottom of the adhesive plate 5, an external thread 3 at the bottom of the outer tube 1, and a bottom cover 2 threaded onto the outer tube 1 via the external thread 3. The bottom cover 2 is provided with at least two circumferentially spaced claw 7 assemblies, which are radially guided and mounted on the bottom cover 2. Each claw 7 assembly is connected to a spring 11 for forcing the claw 7 assembly to move in the axial direction of the bottom cover 2 so that the claw 7 assembly snaps onto the snap-fit ​​edge 6.

[0027] In this embodiment, the inner ring of the bottom cover 2 is provided with an internal thread 4 that matches the external thread 3. The bottom cover 2 is fixed to the bottom of the outer cylinder 1 of the trap by the engagement of the internal thread 4 and the external thread 3. The adhesive plate 5 can be conical or cylindrical. When the adhesive plate 5 is covered with flying insects, it needs to be replaced. People can manually rotate the bottom cover 2 to quickly remove it from the outer cylinder 1 of the trap and take out the adhesive plate 5 on the bottom cover 2. Then, by controlling the radial expansion of the claw 7 assembly, the adhesive plate 5 can be directly removed. At the same time, a new adhesive plate 5 can be placed on the bottom cover 2. When the claw 7 assembly resets, it fixes the adhesive plate 5 to complete the replacement. It is convenient and quick, and greatly reduces the difficulty of replacing the adhesive plate 5.

[0028] like Figure 3 As shown, the bottom cover 2 has at least one sliding groove 12, the claw 7 assembly includes two sets of claws 7 symmetrically arranged in the sliding groove 12, and the bottom cover 2 is provided with a pushing mechanism for pushing the two sets of claws 7 away from each other.

[0029] In this embodiment, the slide 12 guides and limits the claws 7. By setting the pushing mechanism, the claws 7 can be moved away from each other to facilitate the removal of the adhesive plate 5. At the same time, the reset structure can quickly reset the claws 7 to facilitate the clamping of the newly placed adhesive plate 5.

[0030] like Figure 5 As shown, a connecting rod 13 is provided on the claw 7. The end of the connecting rod 13 has an inclined surface. The pushing mechanism includes a conical block 16 disposed between the two connecting rods 13 and matching the inclined surface of the connecting rod 13. A push rod 17 is connected to the bottom of the conical block 16, and the lower end of the push rod 17 extends to the outside of the bottom cover 2.

[0031] In this embodiment, by setting the connecting rod 13, it is easy to contact the conical block 16. The inclined surface can drive the claws 7 to move away from each other. The push rod 17 is provided with anti-detachment rods 18 on both sides. The bottom cover 2 is provided with a through hole that matches the push rod 17. A relief groove is provided on both sides of the through hole to allow the anti-detachment rod 18 to slide up and down, which can prevent the push rod 17 from falling off.

[0032] like Figure 5 As shown, there are two springs 11, which are fixedly installed on both sides of the slide groove 12, and one end of each spring 11 is fixedly connected to one side of the claw 7.

[0033] In this embodiment, by setting a spring 11, when the conical block 16 moves down, the spring 11 pushes the two claws 7 to reset when it resets.

[0034] like Figure 4 As shown, the inner wall of the slide groove 12 is provided with a guide groove (not shown in the figure), and the connecting rod 13 is provided with guide strips 14 on both sides that slide in cooperation with the guide groove.

[0035] In this embodiment, the guide groove guides and limits the guide strip 14 on the connecting rod 13 to prevent the guide strip 14 from leaving the guide groove. The guide strip 14 is fixedly connected to the connecting rod 13, thereby preventing the connecting rod 13 from leaving the guide groove.

[0036] like Figure 2 As shown, the bottom of the adhesive plate 5 is provided with a decoy mounting plate 8, and the decoy mounting plate 8 is detachably mounted on the bottom cover 2 by bolts 10. A decoy 9 is provided on the decoy mounting plate 8, and a vent hole 19 is provided on the adhesive plate 5.

[0037] In this embodiment, the lure mounting plate 8 can be installed and removed by bolts 10 for easy replacement or maintenance, and the insect sex pheromone released by the lure 9 can be discharged through the ventilation hole 19 to attract flying insects to approach the adhesive plate 5 for capture.

[0038] like Figure 1 As shown, a pull rope 21 is fixedly installed on the outer cylinder 1 of the trap, and a hook 15 is fixedly connected to the outer cylinder 1 of the trap via the pull rope 21.

[0039] In this embodiment, the trapping device can be suspended in the area where flying insects gather by setting the hook 15.

[0040] like Figure 2 As shown, multiple extension plates 22 perpendicular to the outer wall of the adhesive plate 5 are arranged circumferentially on the adhesive plate 5, and each trap inlet 20 is located between two corresponding extension plates 22.

[0041] In this embodiment, by setting the extension plate 22, the empty area between the outer cylinder 1 of the trap and the adhesive plate 5 can be fully utilized, increasing the capture area for flying insects and improving the capture efficiency of flying insects. This not only effectively increases the number of flying insects captured, but also reduces the frequency of replacing the adhesive plate 5. The number of extension plates 22 is matched with the number of trap entrances 20 opened.

[0042] Working principle: The lure 9 releases insect sex pheromones or other attractants to attract flying insects. The insects enter the interior of the outer cylinder 1 of the trap through the trap inlet 20. The adhesive plate 5 is coated with a layer of sticky glue. When the flying insects come into contact with the adhesive plate 5, they will stick to it. When the adhesive plate 5 is full of flying insects, it needs to be replaced. The bottom cover 2 can be manually rotated to quickly remove it from the outer cylinder 1 of the trap, and the adhesive plate 5 on the bottom cover 2 will be removed. Then, by pressing the push rod 17, the push rod 17 is moved upward, which drives the conical block 16 to push the multiple connecting rods 13. Open, thereby causing the multiple claws 7 to move away from each other and move away from the locking edge 6 at the bottom of the adhesive plate 5. At this time, the adhesive plate 5 can be directly removed, and the new adhesive plate 5 can be placed on the bottom cover 2. Release the push rod 17, and the spring 11 pushes the claws 7 back to their original position. At this time, the claws 7 lock the locking edge 6 at the bottom of the adhesive plate 5, and fix the adhesive plate 5 to complete the replacement. When using this device, you only need to rotate the bottom cover 2 to directly remove the bottom cover 2, and press the push rod 17 to directly remove the old adhesive plate 5 and complete the replacement. It is convenient and quick, and greatly reduces the difficulty of replacing the adhesive plate 5.
