Description

Technical Field

[0001] This utility model relates to the field of pest control in storage facilities, specifically to a device for trapping pests in tobacco storage. Background Technology

[0002] During the storage and aging process, tobacco is frequently damaged by storage pests, primarily the tobacco whitefly and the tobacco beetle. These pests excrete feces while feeding on tobacco leaves and use their silken threads to bind loose tobacco leaves together. After being eaten, the tobacco leaves develop irregular holes or notches, sometimes leaving only the veins, significantly reducing the yield of tobacco fibers and affecting its usability. Furthermore, the resulting insect carcasses, feces, and silken threads contaminate the tobacco leaves, severely impacting their taste and quality, leading to substantial economic losses. In the control of tobacco storage pests, the combination of tobacco beetle and tobacco whitefly sex pheromone attractants with sticky traps has been widely used. This technique effectively attracts adult tobacco storage pests and has no toxic side effects on humans or animals.

[0003] Chinese utility model patent CN217905915U discloses a prismatic mealybug trapping device, comprising a support column, which is hollow and has an air inlet; a trapping box, which is a regular polyhedral prism, installed at the top of the support column, and the support column is connected to the trapping box, with ventilation holes on the side of the trapping box; a fixing clamp installed on the side of the trapping box for holding the sticky plate; a fan installed inside the support column and located above the air inlet; and a trapping light installed inside the trapping box.

[0004] The aforementioned technologies have the following drawbacks: during the peak season for tobacco pests, especially when the insect population density is high, the sticky traps become covered with pests within a few days, greatly reducing the subsequent trapping effect, and frequent replacement of the sticky traps is time-consuming and labor-intensive.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] This utility model provides a tobacco storage pest trapping device, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a collection box 1, a funnel 2, and a trapping mechanism 3.

[0021] The collection box 1 contains a treatment liquid 11, and the bottom of the collection box 1 is provided with a drain hole 12, and a plug 13 is provided on the drain hole 12.

[0022] The funnel 2 is located on top of the collection box 1.

[0023] The trapping mechanism 3 is located at the bottom of the funnel 2, and the bottom of the funnel 2 is connected to the trapping mechanism 3. The trapping mechanism 3 is connected to the inside of the collection box 1, and the trapping mechanism 3 is slightly higher than the treatment liquid 11.

[0024] In use, the trapping mechanism 3 is located at the bottom of the funnel 2. It releases trapping signals by utilizing the chemotaxis and phototaxis of the tobacco pests, attracting surrounding pests to gather towards the trapping mechanism 3. Since the bottom of the funnel 2 is connected to the trapping mechanism 3, and the funnel 2 has a conical structure that is wider at the top and narrower at the bottom, it forms a natural guide channel, allowing the trapped pests to slide down the inner wall of the funnel 2 into the trapping mechanism 3. The trapping mechanism 3 is connected to the inside of the collection box 1 and is slightly higher than the treatment liquid 11 inside the collection box 1. After the trapped pests enter the trapping mechanism 3, they fall into the treatment liquid 11 inside the collection box 1 through the connecting channel under the action of their own crawling and gravity. The design of the trapping mechanism 3 being slightly higher than the treatment liquid 11 avoids the treatment liquid 11 from evaporating or overflowing and affecting the trapping effect, while ensuring that the pests fall accurately into the liquid, and at the same time preventing the treatment liquid 11 from contacting the trapping mechanism 3 and causing the trapping ingredients to become ineffective. The treatment liquid 11 in the collection box 1 treats pests through chemical killing or physical suffocation, and its liquid capacity is much greater than the capacity of a single sticky plate, allowing for the collection of a large number of pests at once. When a large number of pests accumulate in the collection box 1, there is no need to disassemble the device; simply open the plug 13 on the drain hole 12 to drain the insect-containing waste liquid through the drain hole 12, and then replenish the collection box 1 with new treatment liquid 11 through the funnel 2 to complete the maintenance.

[0025] In this invention, the treatment liquid 11 replaces the traditional sticky plate. Utilizing the large capacity of the liquid, it can hold several times the number of pests as the sticky plate. It can still work stably for several weeks during the peak period of tobacco pests, and the trapping effect is not diminished. The drainage hole 12 enables rapid maintenance of waste liquid discharge and new liquid replenishment, shortening the maintenance time per operation.

[0026] To enhance the adhesion of the treatment solution 11, please refer to... Figure 1 In a preferred embodiment, the treatment liquid 11 is a laundry detergent solution.

[0027] When used, laundry detergent solution has a certain degree of adhesion, which can stick to adult insects and prevent them from flying. In addition, the surfactants such as sodium alkylbenzene sulfonate in laundry detergent can destroy the waxy layer on the surface of the pests.

[0028] For easier assembly and disassembly of funnel 2, please refer to... Figure 1 In a preferred embodiment, the funnel 2 is threaded to the top of the collection box 1.

[0029] When in use, the threaded connection allows for quick disassembly and installation of the funnel 2 and the collection box 1, which can be done without tools or with just a simple wrench: when cleaning the remaining insect corpses and dirt in the collection box 1, the funnel 2 can be unscrewed directly to expose the inside of the collection box 1, making the cleaning more thorough and without dead corners.

[0030] To reduce the likelihood of pests adhering to the inner wall of funnel 2, please refer to... Figure 1 In a preferred embodiment, the trapping device further includes an anti-sticking layer disposed on the inner surface of the funnel 2.

[0031] When in use, the anti-stick layer is a silicone coating with a smooth surface, which can greatly reduce the friction between tobacco pests and the inner wall of funnel 2, and prevent pests from sticking to or getting stuck on the inner wall of funnel 2 when crawling.

[0032] To adjust the height of the trapping device inside the warehouse, please refer to... Figure 1 In a preferred embodiment, the trapping device further includes a hook 4, which is located on the top of the collection box 1 and is used to connect a hanging rope on the roof beam.

[0033] When in use, tobacco pests tend to congregate in the upper part of the tobacco stack. The hook 4 allows for precise suspension of the device at the optimal trapping height by adjusting the rope length, resulting in a higher success rate compared to floor-mounted devices. Simultaneously, it avoids the impact of damp ground and dust on the device, ensuring the stable effectiveness of the trapping mechanism 3 and the detergent solution.

[0034] To achieve odor diffusion in trapping mechanism 3, please refer to... Figure 1In a preferred embodiment, the trapping mechanism 3 includes a trapping tube 31, which contains a trapping agent 32 and has ventilation holes 33.

[0035] In use, the trapping tube 31 is filled with a special attractant 32 for tobacco pests. The evenly distributed ventilation holes 33 on the trapping tube 31 provide a stable channel for odor diffusion. The volatile components of the attractant 32 are slowly released through the ventilation holes 33, which not only avoids the rapid evaporation of the odor and the failure of the attractant 32, but also creates a continuous and uniform odor field. Tobacco pests will move towards the trapping tube 31 along the odor gradient. Since the trapping tube 31 is located at the bottom of the funnel 2, and the funnel 2 has a conical structure that is wider at the top and narrower at the bottom, it forms a natural aggregation channel. After the pests approach the trapping tube 31, driven by the attraction of the odor and their own crawling instinct, they will search for the source of the odor around the trapping tube 31, and finally move through the surface of the tube body around the ventilation holes 33 and the inner wall of the funnel 2 to the ventilation holes 33 below the trapping tube 31, and finally fall into the treatment liquid 11.

[0036] To improve the trapping effect, please refer to... Figure 1 In a preferred embodiment, the vent 33 is radial, with the larger end of the vent 33 located on the side closer to the funnel 2 and the smaller end of the vent 33 located on the side closer to the collection box 1.

[0037] When in use, pests are attracted by the high concentration of odor in the funnel 2 area and will approach the trap 31. Eventually, they will pass through the vent 33 and fall into the treatment liquid 11. The structure of the vent 33 with the large end in and the small end out prevents pests from escaping in the opposite direction and improves the trapping effect.

[0038] For easy replacement of the attractant 32 inside the cylinder 311, please refer to... Figure 1 In a preferred embodiment, the trapping tube 31 includes a tube body 311 and a tube cover 312, wherein the tube cover 312 is threadedly connected to the top of the tube body 311.

[0039] When in use, the cap 312 and the cylinder 311 are connected by threads, and can be opened and closed by rotating without the need for tools. When the attractant 32 in the trapping cylinder 31 evaporates or its effect diminishes, the cap 312 can be unscrewed directly to quickly replenish or replace the attractant 32, shortening the operation time. After replacement, tighten the cap 312. The self-locking nature of the threads ensures a firm connection and prevents the cap 312 from loosening due to vibration or collision.

[0040] To enable quick assembly and disassembly of the trapping tube 31, please refer to... Figure 2In a preferred embodiment, the trapping device further includes an ear plate 5, a positioning rod 51, and a nut 52. The positioning rod 51 is connected to the bottom of the funnel 2, the ear plate 5 is connected to the cylinder 311, the ear plate 5 is provided with a positioning hole 53 for the positioning rod 51 to pass through, and the nut 52 is threaded to the positioning rod 51 and abuts against the ear plate 5 so that the ear plate 5 abuts against the bottom of the funnel 2.

[0041] When in use, simply unscrew the nut 52 to quickly remove the trapping tube 31 for replenishing the bait 32, cleaning the tube body 311, or replacing parts. This shortens the maintenance time per operation. After maintenance, simply align the positioning rod 51 and insert it into the ear plate 5 to reset and lock it. The operation is simple and requires no professional tools, reducing labor costs.

[0042] To improve the stability of the trapping tube 31, please refer to... Figure 2 In a preferred embodiment, the trapping device further includes a pad 54, which is sleeved on the positioning rod 51 and located between the ear plate 5 and the nut 52.

[0043] When in use, the surface friction of the washer 54 is greater than that of the metal contact surfaces of the ear plate 5 and the nut 52. After tightening, it can form an anti-slip combination of the nut 52, washer 54 and ear plate 5, which can effectively resist the risk of loosening of threads caused by warehouse vibration and equipment shaking.

[0044] To better understand this utility model, the following is combined with... Figure 1 - Figure 2 The working principle of a tobacco storage pest trapping device according to the present invention is described in detail below: The trapping mechanism 3 is located at the bottom of the funnel 2. It releases trapping signals by utilizing the chemotaxis and phototaxis of tobacco storage pests, attracting surrounding pests to gather towards the trapping mechanism 3. Since the bottom of the funnel 2 is connected to the trapping mechanism 3, and the funnel 2 has a conical structure that is wider at the top and narrower at the bottom, it forms a natural guide channel, allowing the trapped pests to slide down the inner wall of the funnel 2 into the trapping mechanism 3. The trapping mechanism 3 is connected to the inside of the collection box 1 and is slightly higher than the treatment liquid 11 in the collection box 1. After the trapped pests enter the trapping mechanism 3, they fall into the treatment liquid 11 in the collection box 1 through the connecting channel under the action of their own crawling and gravity. The design of the trapping mechanism 3 being slightly higher than the treatment liquid 11 avoids the treatment liquid 11 from evaporating or overflowing and affecting the trapping effect, ensures that the pests can accurately fall into the liquid, and prevents the treatment liquid 11 from contacting the trapping mechanism 3 and causing the trapping components to become ineffective. The treatment liquid 11 in the collection box 1 treats pests through chemical killing or physical suffocation, and its liquid capacity is much greater than the capacity of a single sticky plate, allowing for the collection of a large number of pests at once. When a large number of pests accumulate in the collection box 1, there is no need to disassemble the device; simply open the plug 13 on the drain hole 12 to drain the insect-containing waste liquid through the drain hole 12, and then replenish the collection box 1 with new treatment liquid 11 through the funnel 2 to complete the maintenance.
