Description

Technical Field

[0001] This utility model relates to the field of pest control technology for grain storage, specifically an environmentally friendly and energy-saving grain pest trap. Background Technology

[0002] Grain is a fundamental material resource for human survival and development. It refers to crops such as grains, beans, and tubers that can be used as staple foods after being planted, harvested, and processed. Common examples include wheat, rice, corn, soybeans, and potatoes. Grain not only provides the human body with core nutrients such as carbohydrates and proteins, but also needs to be stored centrally in grain storage warehouses after harvest. These warehouses must have basic functions such as moisture protection, ventilation, and heat insulation. Some modern warehouses are also equipped with temperature and humidity monitoring systems to delay grain mold and aging by regulating the internal environment. Because grain is rich in nutrients, it is susceptible to storage pests such as corn weevils, rice moths, and grain borers during storage. These pests eat grains and excrete pollutants, leading to a decline in grain quality and quantity loss. Therefore, pest control is a key aspect of grain storage. Common methods include using pest traps to capture and collect pests, combined with regular grain condition inspections, to ensure safe grain storage.

[0003] A search revealed a Chinese patent (CN219146531U) disclosing an insect trapping device, comprising a trapping cone-shaped net and an insect collection tube. The trapping cone-shaped net has an insect inlet at its bottom and an insect outlet at its top. The diameter of the trapping cone-shaped net decreases from the insect inlet to the outlet. An attractant is placed inside the trapping cone-shaped net, which is placed inside the insect collection tube. A collection cavity for collecting insects is formed between the outer wall of the trapping cone-shaped net and the inner wall of the collection tube. The device also includes an insect-blowing fan, placed inside the trapping cone-shaped net, which blows insects entering through the inlet out through the outlet into the collection cavity. An infrared counting sensor is also included to monitor the number of insects entering the collection cavity; the infrared counting sensor is located at the insect outlet. This insect trapping device effectively prevents insects from crawling back and escaping by blowing insects entering the trapping cone-shaped net into the collection cavity through the insect-blowing fan, ensuring the trapping effect.

[0004] The aforementioned patent proposes that the trapping device and the buffer cover work together to allow the trapped pests to enter the collection tube. However, in actual use, the collection tubes are mostly closed, one-piece structures with only an entry channel and no convenient cleaning opening. This design prevents workers from directly contacting the pests collected inside the tube, making it difficult to regularly clean the accumulated insect carcasses and excrement, and also making it impossible to accurately count the number of live pests. Long-term use will not only block the entry channel, affecting the pest collection and monitoring effect, but may also cause secondary pollution of the surrounding grain storage environment due to the accumulation of pollutants inside the tube, weakening the effectiveness of the overall pest control system. Therefore, we propose an environmentally friendly and energy-saving grain pest trap. Utility Model Content

[0005] The technical problem this application aims to solve is that most insect collection cylinders are closed, one-piece structures with only an entry channel for insects and no convenient cleaning opening. This design prevents workers from directly contacting the pests collected inside the cylinder, making it difficult to regularly clean the accumulated insect carcasses and excrement, and also making it impossible to accurately count the number of live pests. Long-term use not only clogs the entry channel, affecting the effectiveness of insect collection and monitoring, but also may lead to bacterial growth due to the accumulation of contaminants inside the cylinder, causing secondary pollution to the surrounding grain storage environment and weakening the overall effectiveness of the pest control system. To address the aforementioned technical problems, this application provides an environmentally friendly and energy-saving grain pest trap, comprising a bottle body. Both ends of the bottle body are conical, with the diameter of the openings at both ends being smaller than that at the middle. Several insect inlet holes are provided on the surface of the bottle body near the upper opening, arranged in a rectangular array. An insect collection tube is provided at the bottom of the bottle body, and the insect collection tube is fitted onto the bottle body. An installation and splicing mechanism is provided between the bottle body and the insect collection tube, which is used to disassemble and connect the bottle body and the insect collection tube.

[0006] In some embodiments, the installation and splicing mechanism includes an upper fixing ring disposed on the surface of the bottle below the insect inlet hole. The outer wall of the upper fixing ring is provided with two upper buckles, which are symmetrically distributed. The surface of the upper fixing ring is provided with two upper fixing bosses, which are symmetrically distributed and arranged in a cross shape with the upper buckles.

[0007] In some embodiments, the installation splicing mechanism further includes a lower splicing mechanism, which includes a lower fixing ring. The outer wall of the lower fixing ring is provided with two lower buckles, which are symmetrically distributed and connected to the inner wall of the insect collection tube. The outer wall of the lower fixing ring is provided with two lower fixing protrusions, which are symmetrically distributed and arranged in a cross shape with the lower buckles.

[0008] In some embodiments, a protective mechanism is provided at the upper end of the bottle body. The protective mechanism includes a light-transmitting plate, a lower rubber ring at the bottom end of the light-transmitting plate, which is sealed to the bottle body, and an upper rubber ring at the top end of the light-transmitting plate, which is sealed to the bottle body. Multiple sets of light-transmitting holes are formed on the surface of the light-transmitting plate. Each set of light-transmitting holes is arranged in a hexagonal shape and is tapered. A fine mesh is provided between the light-transmitting plate and the upper rubber ring, and the fine mesh is pressed against the surface of the light-transmitting plate.

[0009] In some embodiments, the inner wall of the insect collecting tube is provided with a rubber pad, the rubber pad is made of rubber, and the inner wall of the rubber pad presses against the outer wall of the bottom end of the bottle.

[0010] In some embodiments, a stopper is provided at the top of the bottle, and the outer wall of the stopper fits against the inner wall of the bottle.

[0011] In some embodiments, a light source is provided at the bottom of the plug, and the light source is threadedly connected to the plug.

[0012] This utility model has at least the following beneficial effects: 1. In this utility model, the device is disassembled into two parts: a bottle and an insect collection tube. The bottle and the insect collection tube are then assembled using an installation and splicing mechanism. The installation and splicing mechanism consists of an upper fixing ring and a lower fixing ring, which are respectively fixed to the outer wall of the bottle and the inner wall of the insect collection tube. The assembly is completed by twisting the rings so that the upper fixing protrusion is engaged inside the lower buckle and the lower fixing protrusion is engaged inside the upper buckle.

[0013] 2. In this utility model, a protective mechanism is set inside the bottle body below the light source. The protective mechanism consists of a light-transmitting plate, a lower rubber ring, an upper rubber ring, a fine mesh, and light-transmitting holes. The surface of the light-transmitting plate has several light-transmitting holes. The diameter of the light-transmitting holes is smaller at one end near the light source and larger at the other end, which can expand and refract the optical fiber of the light source. A fine mesh is set on the side of the light-transmitting plate near the light source, which can prevent pests from entering and damaging the light source without blocking the light from passing through the light-transmitting plate.

[0016] 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.

[0017] Example 1: Please refer to Figures 1-7 This utility model provides a technical solution: an environmentally friendly and energy-saving grain pest trap, including a bottle body 1, both ends of which are conical, with the diameter of the openings at both ends of the bottle body 1 being smaller than that at the middle. Several insect inlet holes 11 are provided on the surface of the bottle body 1 near the upper opening, arranged in a rectangular array. An insect collection tube 2 is provided at the bottom of the bottle body 1, fitted onto the bottle body 1. An installation and splicing mechanism 3 is provided between the bottle body 1 and the insect collection tube 2, used to detach and connect the bottle body 1 and the insect collection tube 2. A rubber pad 21 is provided on the inner wall of the insect collection tube 2, the rubber pad 21 being made of rubber, and the inner wall of the rubber pad 21 pressing against the outer wall of the bottom end of the bottle body 1. A stopper 5 is provided at the top of the bottle body 1, the outer wall of the stopper 5 fitting against the inner wall of the bottle body 1. A light source 6 is provided at the bottom of the stopper 5, and the light source 6 is threadedly connected to the stopper 5.

[0018] The bottle body 1 has an overall shape that tapers at both ends. Both ends are tapered, and the diameter of the openings at both ends is smaller than the diameter of the middle part of the bottle body 1. This is to accommodate the installation and function of subsequent components. On the outer surface of the bottle body 1, near the opening at the top, there are several insect entry holes 11 for pests to enter. The insect entry holes 11 are distributed in a rectangular array to ensure that pests can enter the bottle body 1 from multiple directions. At the bottom of the bottle body 1, a collection tube 2 for collecting pests is provided. The collection tube 2 is cylindrical in shape and is installed on the outside of the bottom of the bottle body 1 by means of a sleeve, so that part of the bottom structure of the bottle body 1 is located inside the collection tube 2. In order to achieve a stable connection and easy disassembly between the bottle body 1 and the collection tube 2, an installation splicing mechanism 3 is provided between the bottle body 1 and the collection tube 2. The installation splicing mechanism 3 can detachably connect the bottle body 1 and the collection tube 2, which facilitates the subsequent cleaning of the pests collected inside the collection tube 2. A rubber pad 21 is fixedly installed on the inner wall of the insect collecting tube 2. The rubber pad 21 is made of rubber and has a certain elasticity and sealing properties. The inner wall of the rubber pad 21 is tightly pressed against the outer wall of the bottom end of the bottle body 1, which can fill the gap between the insect collecting tube 2 and the bottle body 1. This not only enhances the sealing of the connection between the two and prevents pests from escaping from the gap, but also plays a buffering and protective role during installation and disassembly, avoiding damage caused by hard friction between parts. At the top opening of the bottle body 1, a stopper 5 is provided for sealing the bottle mouth and fixing the light source; the outer wall of the stopper 5 fits tightly against the inner wall of the bottle body 1, which can achieve a seal at the top of the bottle body 1 to prevent external impurities from entering or internal light from leaking out; at the bottom of the stopper 5, a light source lamp 6 is installed to provide a light source; the light source lamp 6 is fixed to the stopper 5 by a threaded connection. This connection method not only facilitates the installation and removal of the light source lamp 6, making it convenient for subsequent maintenance or replacement, but also ensures the stability of the light source lamp 6 during use and avoids positional displacement due to shaking.

[0019] Example 2: Based on Example 1, such as Figures 1-7 As shown, the installation and splicing mechanism 3 includes an upper fixing ring 31 located on the surface of the bottle body 1 below the insect inlet hole 11. The outer wall of the upper fixing ring 31 is provided with two upper buckles 32, which are symmetrically distributed. The surface of the upper fixing ring 31 is provided with two upper fixing protrusions 33, which are symmetrically distributed and form a cross with the upper buckles 32. The installation and splicing mechanism 3 also includes a lower splicing mechanism 34, which includes a lower fixing ring 341. The outer wall of the lower fixing ring 341 is provided with two lower buckles 343, which are symmetrically distributed and connected to the inner wall of the insect collection tube 2. The outer wall of the lower fixing ring 341 is provided with two lower fixing protrusions 342, which are symmetrically distributed and form a cross with the lower buckles 343.

[0020] The installation and splicing mechanism 3 consists of two parts: an upper fixing component and a lower splicing mechanism 34. It is used to splice and disassemble the bottle body 1 and the insect collection tube 2. The upper fixing component includes an upper fixing ring 31 fixedly installed on the outer wall of the bottle body 1. The installation position of the upper fixing ring 31 is located directly below the insect inlet hole 11 on the surface of the bottle body 1, ensuring that it does not affect the function of the insect inlet hole 11 and can be adapted to the inner wall components of the insect collection tube 2. On the outer wall of the upper fixing ring 31, two upper buckles 32 are integrally formed. The two upper buckles 32 are symmetrically distributed along the center of the upper fixing ring 31. At the same time, two upper fixing bosses 33 are also protruding on the outer wall of the upper fixing ring 31. The two upper fixing bosses 33 are also symmetrically distributed along the center of the circle. The upper fixing bosses 33 and the upper buckles 32 are arranged in a cross shape in the circumferential direction to form a staggered layout. Another part of the splicing mechanism 3 is the lower splicing mechanism 34. The core component of the lower splicing mechanism 34 is the lower fixing ring 341. On the outer wall of the lower fixing ring 341, two lower buckles 343 are integrally formed. The two lower buckles 343 are symmetrically distributed along the center of the lower fixing ring 341, and both lower buckles 343 are fixed to the inner wall of the insect collecting tube 2, so that the lower fixing ring 341 is stably installed inside the insect collecting tube 2. At the same time, two lower fixing bosses 342 are also protruding from the outer wall of the lower fixing ring 341. The two lower fixing bosses 342 are symmetrically distributed along the center of the lower fixing ring 341, and the lower fixing bosses 342 and the lower buckles 343 are arranged in a cross shape in the circumferential direction, which matches the layout of the upper fixing bosses 33 and the upper buckles 32 on the upper fixing ring 31. When assembling the equipment, it is necessary to first disassemble the entire equipment into two independent parts: the bottle body 1 and the insect collection tube 2. The upper fixing ring 31 serves as the upper part of the installation and assembly mechanism 3 and is pre-fixed to the outer wall of the bottle body 1; the lower fixing ring 341 serves as the lower part of the installation and assembly mechanism 3 and is pre-fixed to the inner wall of the insect collection tube 2. The assembly operation is completed by twisting: align the bottom end of the bottle body 1 with the upper opening of the insect collection tube 2 and insert it, so that the upper fixing ring 31 and the lower fixing ring 341 are at the same level. Then, rotate the bottle body 1 counterclockwise, causing the upper fixing ring 31 to rotate synchronously until the upper fixing boss 33 on the upper fixing ring 31 is fully engaged with the lower buckle 343 on the lower fixing ring 341, and at the same time, the lower fixing boss 342 on the lower fixing ring 341 is fully engaged with the upper buckle 32 on the upper fixing ring 31, forming a two-way engagement structure, thereby completing the assembly and fixation of the bottle body 1 and the insect collecting tube 2; when disassembling, rotate the bottle body 1 in the opposite direction to separate the boss from the buckle, and the two parts can be separated.

[0021] Example 3: Based on Example 1, such as Figures 1-7 As shown, a protective mechanism 4 is provided at the upper end of the bottle body 1. The protective mechanism 4 includes a light-transmitting plate 41. A lower rubber ring 42 is provided at the bottom end of the light-transmitting plate 41, and the lower rubber ring 42 is sealed to the bottle body 1. An upper rubber ring 43 is provided at the top end of the light-transmitting plate 41, and the upper rubber ring 43 is sealed to the bottle body 1. Multiple sets of light-transmitting holes 45 are opened on the surface of the light-transmitting plate 41. Each set of light-transmitting holes 45 is arranged in a hexagonal shape and is tapered. A fine mesh 44 is provided between the light-transmitting plate 41 and the upper rubber ring 43, and the fine mesh 44 is pressed against the surface of the light-transmitting plate 41. Inside the bottle body 1, and directly below the light source lamp 6, a protective mechanism 4 is fixedly installed. The protective mechanism 4 includes a light-transmitting plate 41, a lower rubber ring 42, an upper rubber ring 43, and a fine mesh 44. The light-transmitting plate 41 is the core component with light transmission function, and its surface is evenly provided with several through-type light-transmitting holes 45 at a preset interval. The light-transmitting hole 45 has a conical structure. The end closer to the light source 6 is the light-inlet end, which has a smaller diameter. The end farther away from the light source 6 is the light-outlet end, which has a larger diameter. With this structural design, the light emitted by the light source 6 can be expanded and refracted along the conical hole wall after entering the light-transmitting hole 45, thereby achieving the effect of light diffusion and light spot enlargement. To achieve the sealing and fixing of the light-transmitting plate 41, a lower rubber ring 42 is installed on the upper end face of the light-transmitting plate 41, and an upper rubber ring 43 is installed on the lower end face. The lower rubber ring 42 and the upper rubber ring 43 can fill the gap between the light-transmitting plate 41 and the inner wall of the bottle body 1, and at the same time play the role of buffering and fixing the light-transmitting plate 41. In addition, a fine mesh 44 is tightly fitted on the surface of the light-transmitting plate 41 and on the side near the upper rubber ring 43. The fine mesh 44 is made of a mesh material with high light transmittance. Without blocking the light from penetrating the light-transmitting plate 41, it can form a physical barrier to prevent external pests from entering the bottle body 1 through the light-transmitting hole 45 or the gap between the light-transmitting plate 41 and other components, thus avoiding damage such as biting and contamination of the light source lamp 6 by pests.

[0022] Based on the above embodiments, the following is the complete working principle of the above embodiments: When in use, the equipment assembly operation must first be completed: First, install the protective mechanism 4 inside the bottle body 1, so that the light-transmitting plate 41 is in a suitable position at the upper end of the bottle body 1. Through the lower rubber ring 42 and the upper rubber ring 43 at the upper and lower ends of the light-transmitting plate 41, the light-transmitting plate 41 and the bottle body 1 are sealed and fixed. At the same time, ensure that the fine mesh 44 is tightly attached to the side of the light-transmitting plate 41 near the upper rubber ring 43. Then, install the light source lamp 6 at the bottom end of the stopper 5 through a threaded connection. Then, insert the stopper 5 into the top opening of the bottle body 1, so that the outer wall of the stopper 5 is tightly attached to the inner wall of the bottle body 1, and the upper end of the bottle body 1 is sealed and the light source lamp 6 is fixed. At this time, the light source lamp 6 is located directly above the light-transmitting plate 41. Next, the bottle body 1 and the insect collection tube 2 are spliced ​​together: the insect collection tube 2 is aligned with the bottom of the bottle body 1 and fitted onto it, so that the upper fixing ring 31 of the splicing mechanism 3 is fixed below the insect inlet hole 11 on the outer wall of the bottle body 1 and the lower fixing ring 341 is fixed on the inner wall of the insect collection tube 2 at the same horizontal height. The bottle body 1 is twisted counterclockwise, which drives the upper fixing ring 31 to rotate synchronously until the upper fixing boss 33 is inserted into the lower buckle 343 and the lower fixing boss 342 is inserted into the upper buckle 32, forming a two-way locking and fixing. At this time, the rubber pad 21 on the inner wall of the insect collection tube 2 is tightly pressed against the outer wall of the bottom of the bottle body 1, filling the gap between the two to prevent pests from escaping. After the equipment is assembled, the light source 6 is turned on. The light emitted by the light source 6 passes through the fine mesh 44 and enters the light-transmitting plate 41. Through the conical light-transmitting hole 45 on the light-transmitting plate 41, the light enters through a small diameter and exits through a large diameter, causing expansion and refraction, which makes the light evenly diffuse into the interior of the bottle 1 and radiate outward. Pests in the grain storage environment are attracted by the light and enter the interior of the bottle 1 through the rectangular array of insect-entry holes 11 on the surface of the bottle 1. They then move downward along the inner wall of the bottle 1 and finally fall into the insect-collecting tube 2 below. The fine mesh 44 can prevent pests that have entered the bottle 1 from climbing upward and contacting and damaging the light source 6 without blocking the light. When it is necessary to clean the pests, twist the bottle body 1 in the opposite direction to disengage the boss and buckle in the splicing mechanism 3, separate the bottle body 1 from the insect collection tube 2, and then clean the pests collected inside the insect collection tube 2. After cleaning, reassemble the equipment according to the splicing steps above, and it can continue to be used for trapping stored grain pests.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
