Description

Technical Field

[0001] This utility model relates to the field of agricultural pest and disease control technology, and in particular to a biodegradable pest and disease control trap. Background Technology

[0002] Pest and disease control is a key link in agricultural production to ensure crop yield and quality. By adopting physical, chemical, and biological methods, we can reduce the damage of pests to crops, reduce the spread of diseases, and thus maintain the stability of the agricultural ecosystem.

[0003] Traps are a commonly used physical control tool in pest and disease management. They work by using the physiological characteristics of pests, such as phototaxis and odor attraction, to attract pests by setting up a pheromone source, thereby capturing or killing them and reducing the number of pests.

[0004] The existing biodegradable pest and disease control trap has the following shortcomings:

[0005] Because the entrance structure is of a fixed size, the gap cannot be adjusted according to the number of pests entering, which makes it easy for pests to escape from the entrance in the opposite direction, affecting the trapping efficiency. At the same time, the existing device lacks a convenient disassembly and assembly design for the bait placement structure, making it cumbersome to replace the bait, and the bait is not securely fixed and is easily detached by external force, affecting the continuous use effect. Utility Model Content

[0006] This invention proposes a biodegradable pest and disease control trap that can achieve dynamic escape prevention, improve the escape prevention effect, and facilitate quick bait replacement to ensure stable use of the device, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a biodegradable pest and disease control trap, comprising a trapping cylinder, a suspension assembly slidably connected to the top center of the trapping cylinder, an insect-attracting channel provided at the bottom end of the trapping cylinder, three bait components arranged in a ring array on the upper surface of the trapping cylinder, a threaded cylinder opening provided at the bottom end of the outer surface of the trapping cylinder, and three through-holes arranged in a ring array on the upper surface of the trapping cylinder.

[0008] The suspension assembly includes a connecting slide rod, which is slidably connected to the middle of the top of the trapping cylinder. A hook is fixedly connected to the top of the connecting slide rod. A support plate is fixedly connected to the upper surface of the outer surface of the connecting slide rod. A tension spring is fixedly connected to the lower surface of the support plate. The bottom end of the tension spring is fixedly connected to the upper surface of the trapping cylinder.

[0009] The insect-attracting channel includes a threaded collar, which is threadedly connected to the outer surface of the threaded cylinder opening. A conical inlet is fixedly connected to the middle of the threaded collar, and the bottom end of the connecting slide rod extends through to the inner side of the conical inlet and is fixedly connected to a conical plug.

[0010] Preferably, the top of the conical inlet is fixedly connected with a number of barbs in an annular array, and the outer surface of the conical inlet is provided with a number of vertically penetrating vent holes in an annular array.

[0011] Preferably, the bait assembly includes a plug-in post, the outer surface of which is slidably connected to the inner surface of the plug-in hole, a limiting baffle is fixedly connected to the top of the plug-in post, the limiting baffle is disposed on the upper surface of the trapping cylinder, and the bottom end of the plug-in post penetrates into the interior of the trapping cylinder and is fixedly connected to liquid absorbent cotton.

[0012] Preferably, the liquid absorbent cotton for moth pests absorbs a slow-release pheromone solution, and the liquid absorbent cotton for flies absorbs a sugar-vinegar mixture.

[0013] Preferably, the top of the plug-in post is provided with a connecting groove, and the front and rear sides of the connecting sliding are slidably connected with connecting slide plates. A clamping spring is fixedly connected to the opposite surfaces of the two connecting slide plates, and a positioning block is fixedly connected to the bottom of the opposite surfaces of the two connecting slide plates. The end of the positioning block away from the connecting slide plate extends through to the outside of the plug-in post and is set on the upper surface of the inner wall of the trapping cylinder.

[0014] Preferably, pressing blocks are fixedly connected to the top of the opposite sides of the two connecting slides, and the end of the pressing block away from the connecting slide extends to the outside of the limiting baffle.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. In this utility model, through the cooperation of the conical inlet, the conical block, the connecting slide rod and the tension spring, the increased weight of the trapping cylinder after the pest enters overcomes the spring force and slides downward, so that the gap between the conical block and the conical inlet gradually narrows until it closes. Combined with the barbed structure, a double protection is formed, realizing the dynamic anti-escape function, solving the problem of easy escape with traditional fixed entrances, and greatly improving the trapping success rate.

[0017] 2. In this utility model, through the cooperation of the plug-in column, the connecting slide plate, the tightening spring and the positioning block, the tightening spring pushes the positioning block into the inner wall of the trapping cylinder to achieve fixation, and the pressing block drives the connecting slide plate to retract to disengage the positioning block, thereby realizing the quick assembly and disassembly of the bait assembly. Compared with the traditional structure, it is easier to replace the bait, and it is firmly fixed and not easy to fall off, ensuring the continuous and stable use of the device.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: it includes a trapping cylinder 1, a suspension assembly 2 slidably connected to the middle of the top of the trapping cylinder 1, an insect-attracting channel 3 provided at the bottom of the trapping cylinder 1, three bait assemblies 4 arranged in a circular array on the upper surface of the trapping cylinder 1, a threaded cylinder opening 11 provided at the bottom of the outer surface of the trapping cylinder 1, and three through-holes 12 arranged in a circular array on the upper surface of the trapping cylinder 1. The suspension assembly 2 includes a connecting slide rod 21, which is slidably connected to the middle of the top of the trapping cylinder 1. A hook 22 is fixedly connected to the top of the connecting slide rod 21, and a support plate 23 is fixedly connected above the outer surface of the connecting slide rod 21. The lower surface of the support plate 23... A tension spring 24 is fixedly connected to the surface of the trapping cylinder 1. The bottom end of the tension spring 24 is fixedly connected to the upper surface of the trapping cylinder 1. The insect-attracting channel 3 includes a threaded collar 31, which is threadedly connected to the outer surface of the threaded cylinder opening 11. A conical inlet 32 ​​is fixedly connected to the middle of the threaded collar 31. The bottom end of the connecting slide rod 21 passes through to the inner side of the conical inlet 32 ​​and is fixedly connected to a conical block 25. Several barbs 33 are fixedly connected to the top of the conical inlet 32 ​​in an annular array. Several vertically penetrating vent holes 34 are opened in an annular array on the outer surface of the conical inlet 32. The trapping cylinder 1 and the suspension assembly 2 are both made of polylactic acid biodegradable material, and the surface is coated with a weather-resistant coating.

[0026] The overall effect achieved by Embodiment 1 is as follows: the application of polylactic acid biodegradable materials allows the device to degrade naturally after its service life, reducing environmental pollution; the threaded connection structure between the threaded collar 31 and the threaded cylinder 11 facilitates the disassembly and cleaning of the insect-attracting channel 3, ensuring the cleanliness of the conical inlet 32 ​​to maintain the trapping effect; the setting of the vent 34 allows the bait scent to diffuse outward through the conical inlet 32, enhancing the attraction to pests, while the barbs 33 effectively prevent the entering pests from escaping upwards, and the dynamic gap adjustment structure greatly improves the escape prevention performance.

[0027] Example 2: As Figure 4As shown, this utility model provides a technical solution: the bait assembly 4 includes a plug-in post 41, the outer surface of the plug-in post 41 is slidably connected to the inner surface of the plug-in hole 12, a limiting baffle 42 is fixedly connected to the top of the plug-in post 41, the limiting baffle 42 is disposed on the upper surface of the trapping cylinder 1, the bottom end of the plug-in post 41 penetrates into the interior of the trapping cylinder 1 and is fixedly connected to a liquid absorbent cotton 43, the liquid absorbent cotton 43 absorbs pheromone slow-release liquid for moth pests, and absorbs a sugar-vinegar mixture for flies, the top of the plug-in post 41 has an opening There is a connecting groove, and connecting slide plates 44 are slidably connected to the front and rear sides of the connecting slide. A clamping spring 45 is fixedly connected to the opposite face of the two connecting slide plates 44. A positioning block 46 is fixedly connected to the bottom of the opposite face of the two connecting slide plates 44. The end of the positioning block 46 away from the connecting slide plate 44 extends through to the outside of the plug-in post 41 and is set on the upper surface of the inner wall of the trapping cylinder 1. A pressing block 47 is fixedly connected to the top of the opposite face of the two connecting slide plates 44. The end of the pressing block 47 away from the connecting slide plate 44 extends through to the outside of the limiting baffle 42.

[0028] The overall effect of Embodiment 2 is as follows: the adsorption of liquid bait by the liquid absorbent cotton 43 reduces liquid loss and prolongs the effective action time of the bait; specific baits are set for different pest species, which improves the targeting and efficiency of trapping; the cooperation of the clamping spring 45, the connecting slide plate 44 and the positioning block 46 realizes the quick assembly and disassembly of the bait component 4. Disassembly can be completed by simply pressing the pressing block 47, which is convenient to operate and the fixed structure is stable, which can effectively prevent the device from falling off due to external forces such as wind and rain, and ensure the continuous and stable operation of the device.

[0029] The working principle of the entire device is as follows: In use, the device is first suspended at a suitable location near the crop using hook 22. Depending on the target pest species, the corresponding bait is added to the liquid absorbent cotton 43. Then, the insertion post 41 of the bait assembly 4 is inserted into the insertion hole 12 of the trapping cylinder 1. At this time, the tightening spring 45 pushes the connecting slide plate 44 to open to both sides, causing the positioning block 46 to engage with the upper surface of the inner wall of the trapping cylinder 1. This, combined with the limiting baffle 42, secures the bait assembly 4. The scent emitted by the bait diffuses through the internal space of the trapping cylinder 1 and spreads outward through the ventilation holes 34 of the conical inlet 32, attracting pests. After being attracted, the pests enter the trapping cylinder 1 through the initial gap between the conical inlet 32 ​​and the conical block 25. Due to the obstruction of the barbs 33, the pests have difficulty flying out the other way around from the entrance. As the number of pests entering the trapping cylinder 1 increases, the trapping cylinder 1... As the overall weight gradually increases, when the weight exceeds the elastic force of the tension spring 24, the trapping cylinder 1 slides downward along the connecting slide rod 21, causing the conical inlet 32 ​​to move downward synchronously. This gradually narrows the gap between the conical inlet 32 ​​and the conical block 25 until they are completely closed, forming a physical barrier to further prevent pests from escaping. When it is necessary to replace the bait, press the pressing blocks 47 on both sides to drive the connecting slide plate 44 to compress the top spring 45 and move it towards the center, causing the positioning block 46 to retract into the connecting slide groove. The bait assembly 4 can then be pulled out from the insertion hole 12 for replacement. If it is necessary to clean the pests inside the trapping cylinder 1, the threaded collar 31 can be rotated to separate it from the threaded cylinder opening 11. After removing the insect-attracting channel 3, it can be cleaned. After cleaning, it can be reinstalled and used again. The whole process does not require complicated operation, and the device uses biodegradable materials, which is in line with the concept of green and environmentally friendly agricultural production.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
