Abstract

This invention discloses a grain storage pest trapping device. The technical solution of this invention involves providing an inlet hole in the portion of the device inserted into the grain pile and an inlet opening in the portion exposed on the grain pile surface. This allows crawling pests living inside the grain pile to enter through the inlet hole, while crawling pests living on the grain surface and flying pests living on or above the grain surface can enter through the inlet opening.

Description

Technical Field

[0001] This invention relates to the field of pest control equipment technology, and in particular to a grain storage pest trapping device. Background Technology

[0002] In addition to preventing moisture, fire, and lightning strikes, pests must also be prevented during grain storage. There are various methods for controlling stored grain pests, one of which is physical pest control by placing pest traps in the grain warehouse.

[0003] Currently, over one hundred species of stored grain pests have been recorded in my country, belonging to several families within the orders Coleoptera, Lepidoptera, Blattodea, Pseudoratoides, Thysanura, and Arachnida. Major species include weevils, grain beetles, large flour beetles, saw-toothed flour beetles, long-horned flat flour beetles, red flour beetles, wheat moths, Indian meal borers, and carrion mites. In other words, crawling pests and flying pests usually coexist in the same grain pile; crawling pests typically live inside the grain pile, while flying pests typically live on the grain surface.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0055] This invention proposes a pest trapping device for grain storage.

[0056] In embodiments of the present invention, such as Figures 1 to 16 As shown, the grain storage pest trapping device 10 includes a housing 100, a mounting base 200, and a lighting module 300. The housing 100 has a receiving cavity 102 with an opening 101 on its top surface, and an insect inlet 103 communicating with the receiving cavity 102. The mounting base 200 is located above the housing 100 and is connected to the housing 100 at the opening 101. The mounting base 200 has an insect inlet 201 communicating with the receiving cavity 102. When the grain storage pest trapping device is inserted into a grain pile, the insect inlet 201 is exposed outside the grain pile. The lighting module 300 protrudes into the receiving cavity 102 through the mounting base.

[0057] The technical solution of this invention provides an inlet hole 103 in the portion of the grain pile into which the pest trapping device 10 is inserted, and an inlet 201 in the portion exposed on the surface of the grain pile. This allows crawling pests living inside the grain pile to enter through the inlet hole 103, while crawling pests living on the grain surface and flying pests living on or above the grain surface can enter through the inlet 201. Thus, the pest trapping device 10 provided by this invention can simultaneously trap both crawling and flying pests. Furthermore, the technical solution of this invention also optimizes the structure of the pest trapping device 10 by mounting a light module 300 on the mounting base 200, with one end of the light module 300 extending into the receiving cavity 102 and along the length of the housing 100. In this way, one light module 300 can simultaneously cover the trapping light needs of both the inlet 201 and the inlet hole 103.

[0058] The grain storage pest trapping device 10 can be inserted into the grain pile, meaning it can also be left uninserted. Understandably, in this embodiment, it is usually necessary to insert the grain storage pest trapping device 10 into the grain pile to simultaneously trap both crawling and flying pests.

[0059] Typically, the shell 100 forms a receiving cavity 102, and the shell 100 also has an opening 101, or the shell 100 is provided with an opening 101 on one side. The periphery of the shell 100 is provided with an insect inlet 103 communicating with the receiving cavity 102. Since the shell 100 is inserted into the grain pile, crawling pests such as weevils and grain borers can enter the receiving cavity through the insect inlet 103. In addition, the grain silo pest trapping device 10 also includes a mounting base 200, which is installed on the shell 100 at the opening 101. The mounting base 200 is provided with an insect inlet 201 communicating with the receiving cavity 102, and the insect inlet 201 is exposed on the surface of the grain pile, so that flying pests such as wheat moths and Indian meal borers can enter through the insect inlet 201. The shell 100 has many shapes, including regular shapes such as a cylinder 110, a cuboid, or a cube, as well as other irregular shapes. Preferably, in order to reduce manufacturing difficulty and facilitate subsequent cleaning, the housing 100 is arranged in a regular shape.

[0060] For ease of description, the following description uses a cylindrical shape (110) as an example.

[0061] To facilitate the insertion of the grain pest trapping device 10 into the grain pile, the bottom end of the housing 100 is tapered. That is, the housing 100 includes a cylinder 110 and a conical portion 120. The cylinder 110 and the conical portion 120 can be integrally formed or separate parts. For ease of processing, the cylinder 110 and the conical portion 120 are usually separate parts. Specifically, the cylinder 110 has an upper end and a lower end opposite to each other, and both the upper and lower end faces are provided with openings 101. Preferably, the openings 101 on the end faces of the upper and lower ends are open, which facilitates processing and simplifies the structure of the cylinder 110. The conical portion 120 closes the opening 101 on the lower end face of the cylinder 110, and the mounting base 200 is mounted on the upper end face of the cylinder 110.

[0062] The cone 120 and the cylinder 110 can be detachably connected or fixedly connected. A detachable connection between the cone 120 and the cylinder 110 is more effective when the grain pest trapping device 10 is not inserted into the grain pile; a fixed connection between the cone 120 and the cylinder 110 is more effective when the grain pest trapping device 10 is inserted into the grain pile. Understandably, the insect collection chamber 410 is usually located inside the housing 100 near the cone 120. When the grain pest trapping device 10 is not inserted into the grain pile, a detachable connection between the cone 120 and the cylinder 110 makes it easier to remove the insect collection chamber 410 to clean out the pests inside. In addition, in the scenario where the grain pest trapping device 10 is inserted into the grain pile, the frictional force at the connection between the cylinder 110 and the cone 120 is relatively large during the process of inserting the grain pest trapping device 10 into the grain pile. The fixed connection between the cone 120 and the cylinder 110 can enhance the strength of the connection between the cylinder 110 and the cone 120.

[0063] Furthermore, the insect inlet 103 and the insect inlet 201 can have many shapes. They can be one or more regular shapes such as circles, ovals, squares or triangles, or one or more irregular shapes. In order to reduce the difficulty of processing, one or more regular shapes are usually used.

[0064] Considering that the grains stored in granaries typically include rice, wheat, beans, and coarse grains, rice generally includes japonica rice, indica rice, glutinous rice, upland rice, and deep-water rice; wheat includes wheat, barley, highland barley, rye, and oats; beans include soybeans, red beans, mung beans, and kidney beans; and coarse grains include corn, sorghum, buckwheat, millet, and sorghum. These grains are diverse, with some similar in appearance and others quite different, and their sizes also vary.

[0065] Based on this, in a preferred embodiment, to improve the versatility of the grain storage pest trapping device 10, the insect inlet 103 includes a first insect inlet 103a and a second insect inlet 103b; the first insect inlet 103a is elongated, and the second insect inlet 103b is circular. Thus, by providing at least two shapes of insect inlet 103, including both elongated and circular shapes, the insect inlets on the cylinder 110 are not so easily blocked, thereby improving the versatility of the grain storage pest trapping device 10.

[0066] Understandably, the opening area of ​​the first insect hole 103a and the second insect hole 103b can be adjusted according to the size of the grain being used. For example, the opening area of ​​the insect hole 103 used in soybean trapping equipment is larger than that used in rice trapping equipment.

[0067] Based on the previous embodiment, the first wormhole 103a and the second wormhole 103b are arranged alternately along the length of the cylinder 110; and / or, the first wormhole 103a and the second wormhole 103b are arranged alternately along the circumference of the cylinder 110. That is, in this embodiment, there are three possible arrangements of the first wormhole 103a and the second wormhole 103b:

[0068] First, along the length of the cylinder 110, the first insect holes 103a and the second insect holes 103b are arranged alternately, while other arrangements are used along the circumference of the cylinder 110, with adjacent insect holes 103 spaced apart. Second, along the circumference of the cylinder 110, the first insect holes 103a and the second insect holes 103b are arranged alternately, while other arrangements are used along the length of the cylinder 110, with adjacent insect holes 103 spaced apart. Third, along both the length and circumference of the cylinder 110, the first insect holes 103a and the second insect holes 103b are arranged alternately. In this way, by alternating the first insect holes 103a and the second insect holes 103b, the insect holes 103 adapted to different grains are evenly distributed, thereby preventing local areas of the insect holes 103 from being blocked by grain, thus preventing pests from entering.

[0069] Please see Figure 7 , Figure 15 and Figure 16 In one embodiment, the mounting base 200 includes a base 210 and a support frame 220; the base 210 is connected to the housing 100 at the opening 101, and the support frame 220 is located above the base 210; the insect inlet 201 is provided on the support frame 220.

[0070] Based on the previous embodiment, the base 210 includes a first connecting cylinder 211, a second connecting cylinder 212, and a connecting part that connects the first connecting cylinder 211 and the second connecting cylinder 212; the first connecting cylinder 211, the connecting part, and the second connecting cylinder 212 form an annular groove 202; one end of the housing 100 with the opening 101 extends into the annular groove 202 and engages with the base 210.

[0071] Exemplarily, the base 210 includes a first connecting cylinder 211, a second connecting cylinder 212, a first connecting portion 213, and a connecting rib 214; the first connecting cylinder 211, the first connecting portion 213, and the second connecting cylinder 212 enclose an annular groove 202; the connecting rib 214 is disposed within the annular groove 202, and both ends of the connecting rib 214 are respectively connected to the first connecting cylinder 211 and the first connecting portion 213, and there is a gap between the connecting rib 214 and the first connecting portion 213, thereby forming the first slot 203. When the mounting base 200 is installed on the cylinder 110, the connecting rib 214 is engaged in the first mounting slot 112. In other embodiments, the cylinder 110 and the base 210 can be connected in other ways to facilitate the installation of the cylinder 110 and the base 210.

[0072] To improve the strength of the connecting rib 214, the base 210 further includes a reinforcing ring rib 216, which is disposed between the first connecting cylinder 211 and the second connecting cylinder 212 and connected to the first connecting portion 213. Preferably, the reinforcing ring rib 216 is coaxially arranged with the first connecting cylinder 211 and the second connecting cylinder 212. Additionally, to further enhance the overall strength of the base 210, the base 210 also includes a skirt 215, which is connected to the second connecting cylinder, or the skirt 215 is connected to the first connecting portion 213. The skirt 215 typically extends downwards at an angle from the first connecting portion 213 / second connecting cylinder 212.

[0073] In another embodiment, the support frame 220 includes a support portion 221 and a second top plate 222 disposed above the support portion 221. The support frame 220 includes a plurality of support portions 221, which are spaced apart circumferentially along the second top plate 222, forming the insect inlet 201 between adjacent support portions 221. Thus, the electrical control box 600 can be installed above the second top plate 222, and the lighting module 300 can be installed below the second top plate 222, thereby optimizing the overall structure of the grain storage pest trapping device 10 and making its internal arrangement more rational. In other embodiments, to reduce the number of openings in the second top plate 222 and thus increase its strength, the lighting module 300 can be installed on the first base plate 630. Preferably, the support portion 221 is thickened to strengthen the support frame 220.

[0074] In one embodiment, the grain storage pest trapping device 10 includes an electrical control box 600. To facilitate the installation and positioning of the electrical control box 600, the support portion 221 has an upwardly protruding fixing ring 223 formed on its top surface. The inner sidewall of the fixing ring 223 mates with the outer sidewall of the electrical control box 600. Alternatively, the inner sidewall of the fixing ring can be in clearance fit with the outer sidewall of the electrical control box 600, or the electrical control box 600 can be embedded within the fixing ring.

[0075] It is understood that the control box 600 is usually equipped with a control unit and a power interface for connecting to an external power source. In other embodiments, a battery may be installed inside the control box 600.

[0076] For example, please refer to Figure 3 The electrical control box 600 includes a first top plate 610, a first bottom plate 630, and a middle cylinder 620; the middle cylinder 620 connects the first top plate 610 and the first bottom plate 630, and the outer side wall of the middle cylinder 620 contacts the inner side wall of the fixing ring 223; the first bottom plate 630 is fixedly connected to the second top plate 222. This configuration allows the electrical control box 600 to be easily installed on the mounting base 200.

[0077] The middle cylinder 620, the first bottom plate 630, and the first top plate 610 are all made of flame-retardant or non-flammable materials to prevent the aftershocks from being confined to the sealed space of the control box 600 when the electrical components inside the control box 600 experience arcing or other malfunctions. This will prevent the control box 600 from igniting and thus prevent grain storage safety accidents, thereby improving the safety of the grain storage pest trapping device 10.

[0078] To ensure the structural strength and heat dissipation performance of the middle cylinder 620, the middle cylinder 620 is made of metal or alloy. In particular, to facilitate the production of the middle cylinder 620, the entire middle cylinder 620 is arranged in the shape of a hollow cylinder 110, and the first bottom plate 630 and the first top plate 610 are covered at opposite ends of the middle cylinder 620 to seal the accommodating space and form a sealed space.

[0079] In this embodiment, to facilitate the installation of the grain silo pest trapping device 10, the first bottom plate 630 and the first top plate 610 can be connected and fixed to the middle cylinder 620 by screws or other connectors 311. Of course, in other embodiments, the middle cylinder 620 can be pre-assembled by welding with the first bottom plate 630 and the first top plate 610, and then the entire explosion-proof structure can be fixed to the main body of the device before being placed in the grain silo. Of course, it is also feasible for the first top plate 610 and the middle cylinder 620 to be integrally formed, which is not limited here.

[0080] In a preferred embodiment, to facilitate the removal of the grain pest trapping device 10 from the grain pile, the grain pest trapping device 10 further includes a handle 800, which is installed on the upper part of the grain pest trapping device 10. Further, to facilitate the direct removal of components such as the insect collecting component 400, the electrical control box 600, and the camera component 500, which are mounted on the mounting base 200, the handle 800 is installed on the base 210, or the handle 800 is installed on the electrical control box 600. Preferably, the handle 800 is installed on the first top plate 610 and located above the first top plate 610. In other embodiments, the handle 800 may be installed in other locations; generally, it is located above the housing 100, as long as it facilitates the removal of the grain pest trapping device 10 from the grain pile.

[0081] In one embodiment, the lighting module 300 includes a heat dissipation component 310 and a light source component 320. One end of the heat dissipation component 310 is fixedly connected to the second top plate 222, and the other end extends into the receiving cavity 102. The light source component 320 is installed on the heat dissipation component 310 and extends along the length of the housing 100. Since the light source component 320 generates heat during continuous operation, failure to dissipate this heat could lead to safety accidents within the grain silo. Furthermore, the light source component 320 installed within the heat dissipation component 310 may be damaged due to overheating or result in low working efficiency. Therefore, in this embodiment, by using the heat dissipation component 310 as a connecting component, the structure for installing the light source component 320 is reduced, and the structure of the grain silo pest trapping device 10 is optimized. The heat dissipation component 310 has an installation position for the light source component 320. By integrating the light source component 320 into the heat dissipation component 310, the internal wiring of the grain silo pest trapping device 10 becomes simpler and more convenient, and it is less prone to accidents such as explosions, resulting in higher safety performance.

[0082] It should be noted that this invention is based on the phototaxis of pests to trap them. Typically, a specific light module 300 is installed on the grain warehouse pest trapping device 10. The light source component 320 on the light module 300 emits light that attracts target pests. By attracting the pests into the trapping device, and preferably, the trapping device can be equipped with devices that physically kill the pests, thereby improving the pest-killing efficiency. The wavelength of the light emitted by the light source component 320 is usually determined based on the application scenario or the light waves that the target insects are attracted to.

[0083] Based on the previous embodiment, the heat dissipation assembly 310 includes a connector 311 and a plurality of heat sink groups 312 disposed on the outer periphery of the connector 311; one end of the connector 311 is connected to the second top plate 222, and the other end extends into the receiving cavity 102; the plurality of heat sink groups 312 are arranged at intervals along the circumference of the connector 311 and extend along the length direction of the connector 311; a third mounting groove 301 is formed between two adjacent groups of heat sink groups 312, and the light source assembly 320 is disposed in the third mounting groove 301. Thus, by providing the third mounting groove 301, the light source assembly 320 can be directly inserted into the third mounting groove 301, reducing the number of mounting components for fixing the light source assembly 320.

[0084] The connector 311 can be cylindrical or rectangular, etc., and its shape is not limited here. In this embodiment, for ease of processing, the connector 311 is cylindrical. The connector 311 is mounted on the mounting base 200. Multiple heat dissipation fins are protruding on the outer peripheral wall of the connector 311. The multiple heat dissipation fins form a heat dissipation fin group 312. The heat dissipation fin group 312 increases the heat dissipation area of ​​the outer wall surface of the connector 311, thereby improving the heat dissipation efficiency of the connector 311. This allows for better heat dissipation performance of the light source assembly 320 or other heat-generating components mounted on the connector 311.

[0085] Furthermore, to enhance the heat dissipation performance of the connector 311, multiple heat dissipation fins extend vertically, meaning the gap between adjacent heat dissipation fins extends along the length of the cylinder 110, allowing heat to dissipate from the mounting base 200 and the installed insect inlet 103. Preferably, the connector 311 is made of metal or alloy.

[0086] Optionally, the connector 311 is supported by metal or alloy components, resulting in higher strength and better safety performance. Simultaneously, due to the good thermal conductivity of metal and alloy components, the heat generated by the light source assembly 320 can be quickly transferred away. Combined with the heat sink assembly 312 on the outer periphery of the connector 311, better heat dissipation can be achieved.

[0087] For example, such as Figure 7 , Figure 13 as well as Figure 14 As shown, the heat sink group 312 is a plurality of groups arranged at intervals, and a third mounting groove 301 is formed between two adjacent groups of heat sink groups 312. The third mounting groove 301 is used to install the light source assembly 320. The heat sink group 312 can be a single group, or it can be 2, 3, 4, 6, 8 or more groups arranged at intervals, depending on the volume of the connector 311.

[0088] In this embodiment, the light source assembly 320 is mounted on the outer peripheral wall of the connector 311, allowing it to contact the outside environment, thus enabling the heat from the light source assembly 320 to dissipate more quickly. In this embodiment, as... Figure 14 As shown, considering that the grain pest trapping device 10 inserted into the grain pile cannot be too large, taking the heat sink group 312 as an example of three sets arranged at intervals, the outer peripheral wall of the connector 311 has three spaced third mounting slots 301 for the installation and fixation of the light source assembly 320. This makes the installation of the mounting assembly more stable, and the heat emitted by the light source assembly 320 will be transferred to the adjacent heat sink group 312 in the first time, further improving its heat dissipation efficiency and avoiding damage to the light source assembly 320.

[0089] It should be noted that the light source assembly 320 includes a light module, a reflector, and a shockproof glass stacked sequentially. The mounting space between two adjacent heat sink groups 312 is defined as a third mounting groove 301. This third mounting groove 301 is used to mount and fix the light source assembly 320. The light module has a protruding positioning post corresponding to the positioning hole. The positioning post is inserted into the positioning hole to fix the entire light source assembly 320 within the third mounting groove 301. The light module is used to emit light in a specific phototropic wavelength band. The reflector covers the surface of the light module to improve light utilization, greatly increasing the efficiency of the light module and improving its working efficiency. The shockproof glass protects the light module and reflector from damage caused by external impact. Each adjacent heat sink fin of the two adjacent heat sink groups 312 has a correspondingly arranged recess to form a slot for the reflector and the shockproof glass to be inserted. Figure 14 As shown, the reflector and the explosion-proof glass are prevented from detaching from the third mounting slot 301 without the need for other fasteners to secure them. Optionally, to facilitate the production of the heat dissipation assembly 310, the entire connector 311 can be arranged in the shape of a hollow cylinder 110; of course, in other embodiments, it can also be other irregular shapes.

[0090] In one embodiment, to facilitate the removal of pests from the trapping device, the grain silo pest trapping device 10 includes an insect collecting component 400. The insect collecting component 400 includes an insect collecting chamber 410 and a mounting bracket 420, with the mounting bracket 420 disposed within the receiving cavity 102. The insect collecting chamber 410 is detachably connected to the mounting bracket 420. Thus, the mounting bracket 420 prevents direct connection between the insect collecting chamber 410 and the connector 311. Furthermore, this design allows for the replacement of different insect collecting chambers 410 by changing the mounting bracket 420, thereby improving the versatility of the insect collecting chamber 410's fixing structure. Additionally, by providing an independent insect collecting chamber 410 and detachably connecting it, pests in the insect collecting chamber 410 can be quickly removed, and cleaning of the insect collecting chamber 410 is convenient. The detachable connection can be a plug-in, snap-fit, or threaded connection; preferably, the insect collecting chamber 410 is snap-fitted to the mounting bracket 420.

[0091] Please see Figures 7 to 12 The mounting bracket 420 includes a bracket body, a plurality of third snap-fit ​​portions 423a and a plurality of second connecting portions 421a disposed on the bracket body; the third snap-fit ​​portions 423a and the second connecting portions 421a are respectively located at opposite ends of the bracket body; wherein, the plurality of second connecting portions 421a are used to connect with other components of the grain storage pest trapping device 10, thereby installing the insect collecting assembly 400 in the receiving cavity 102. For example, the plurality of second connecting portions 421a can be directly connected to the cylinder 110, or can be connected to the connector 311 of the light module 300, etc. The inlet of the insect collecting chamber 410 is connected to the mounting base 200, wherein either one end of the mounting bracket 420 provided with a guide portion extends into the insect collecting chamber 410, or the insect collecting chamber 410 extends into the mounting bracket 420.

[0092] The insect collection chamber 410 includes a chamber body 411. The chamber body 411 is provided with a second slot 412 near its inlet for the third locking part 423a to engage. The number of second slots 412 usually corresponds to the number of third locking parts 423a. The number of third locking parts 423a and second slots 412 can be two, three, four, or five, etc., as long as it is easy to disassemble and assemble and the connection between the insect collection chamber 410 and the mounting bracket 420 has sufficient strength. Of course, in terms of manufacturing process, the simpler the structure of the mounting bracket 420, the better. Therefore, it is optimal for the number of third locking parts 423a and second slots 412 to be three or four.

[0093] Preferably, the second connecting part 421a is a connector 311 that is directly or indirectly connected to the lighting module 300. This allows for a detachable connection between the insect collection chamber 410 and the housing 100, and facilitates easy detachment, enabling the insect collection chamber 410 to be removed without moving the housing 100. For ease of explanation, the following description will use the installation of the insect collection assembly 400 onto the lighting module 300 as an example.

[0094] For example, the support body includes a third connecting cylinder 421, a fourth connecting cylinder 422, and a fifth connecting cylinder 423 connected sequentially from top to bottom. The fifth connecting cylinder 423 is located near the insect collection chamber 410. The plurality of third snap-fit ​​portions 423a are located on the outer periphery of the fifth connecting cylinder 423 and are arranged at intervals along the circumference of the fifth connecting cylinder 423. The outer diameter of the third connecting cylinder 421 is relatively large, basically fitting with the inner diameter of the cylinder 110 with a clearance. The outer diameter of the third connecting cylinder 421 allows pests to fall into the insect collection chamber 410 as much as possible, facilitating pest removal. The axial length of the third connecting cylinder 421 is relatively short to improve the assembly and disassembly efficiency of the insect collection assembly 400. In addition, the second connecting portions 421a are located inside the third connecting cylinder 421 and are arranged at intervals along the circumference of the third connecting cylinder 421. The fourth connecting cylinder 422 connects the fifth connecting cylinder 423 and the third connecting cylinder 421, and the outer diameter gradually decreases from the third connecting cylinder 421 toward the fifth connecting cylinder 423, which makes it easier to extend the insect collection chamber 410 into the receiving cavity 102.

[0095] Furthermore, to further improve the assembly and disassembly efficiency of the insect collection chamber 410 and the mounting bracket 420, thereby increasing the efficiency of cleaning pests inside the trapping device, the insect collection chamber 410 also includes a guide protrusion 413. The third engaging portion 423a has a guide groove 423b that matches the guide protrusion 413. During the rotation of the insect collection chamber 410 relative to the mounting bracket 420, the guide protrusion 413 can engage with the guide groove 423b, and the third engaging portion 423a can embed itself into the second engaging slot 412. Thus, by providing the guide protrusion 413 and the guide groove 423b, the alignment speed of the insect collection chamber 410 and the mounting bracket 420 is improved during installation, thereby increasing the installation efficiency of the insect collection chamber 410.

[0096] Preferably, the outer periphery of the fourth connecting cylinder 422 is provided with positioning ribs 422a to prevent the fifth connecting cylinder 423 from extending too deeply into the insect collection chamber 410 during installation. The positioning ribs 422a can be integrally formed annular positioning ribs 422a, or they can be one or more non-annular positioning ribs 422a. In embodiments with multiple positioning ribs 422a, they are typically arranged at intervals along the outer periphery of the fourth connecting cylinder 422.

[0097] It should be noted that there is a large gap between the light module 300 and the cylinder 110 to facilitate the entry of pests from the insect inlet 201 and the insect inlet hole 103 into the insect collection chamber 410. Furthermore, although the mounting bracket 420 is located at the inlet of the insect collection chamber 410, the inlet of the insect collection chamber 410 must have sufficient opening area to allow pests to fall into the insect collection chamber 410.

[0098] In another embodiment, please refer to Figure 7 and Figure 8 The insect collection chamber 410 has a gripping part 414 at the bottom of the chamber body 411 so that the user can hold it when the insect collection chamber 410 is removed.

[0099] In one embodiment, in order to facilitate monitoring of the insect collection situation in the insect collection chamber 410 of the insect collection box, the grain warehouse pest trapping device 10 includes a camera component 500 for monitoring the insect collection situation in the insect collection chamber 410 of the insect collection component 400.

[0100] The camera assembly 500 includes a storage box 510 and a camera 520. The storage box 510 includes a second base plate 511 and an upper cover 512 covering the second base plate 511. The camera 520 is typically mounted on the second base plate 511 and then covered by the upper cover 512. The camera 520 is aimed at the entrance of the insect collection chamber 410 to capture photos of the inside of the chamber, either periodically or in real-time. The captured photos are then transmitted back to the backend for analysis, thereby monitoring the insect collection situation within the insect collection chamber 410. It is understood that the second base plate 511 is typically made of transparent material to allow the camera 520 to capture images of the inside of the chamber while preventing pests from sticking to the lens of the camera 520, thus protecting the camera 520 to a certain extent.

[0101] Furthermore, the storage box 510 is installed on the connector 311. Thus, by directly installing the storage box 510 on the connector 311, the heat generated by the camera 520 can be dissipated through the heat dissipation component 310. In addition, since the connector 311 is hollow, the connection point between the camera 520 and the control unit inside the control box 600 can be directly through the connector 311, thereby hiding the wiring of the camera 520 and the control unit, thus optimizing the internal structure of the grain warehouse pest trapping device 10 to a certain extent.

[0102] Furthermore, the mounting bracket 420 is connected to the storage box 510, meaning that the insect collecting component 400 is mounted on the heat dissipation component 310 via the storage box 510. In this embodiment, the mounting base 200 is detachably connected to the housing 100. The electrical control box 600 and the heat dissipation component 310 are mounted on the mounting base 200, and the camera component 500 and the insect collecting component 400 are both mounted on the heat dissipation component 310. Thus, in the scenario of inserting it into a grain pile, cleaning pests inside the insect collecting chamber 410, and maintaining the electrical control box 600, the light module 300, or the camera component 500, does not require removing the entire grain silo pest trapping device 10. This reduces the number of times the grain silo pest trapping device 10 needs to be inserted, thereby increasing the lifespan of the grain silo pest trapping device 10, simplifying the work steps for cleaning pests inside the trapping device, reducing the difficulty of cleaning pests inside the trapping device, and improving the work efficiency of cleaning pests inside the trapping device.

[0103] Please see 1 and Figure 3 In one embodiment, the housing 100 includes a cylinder 110 and a conical portion 120 mounted on the bottom of the cylinder 110; a receiving cavity 102 is enclosed between the cylinder 110 and the conical portion 120, and an opening 101 is formed on the top surface of the cylinder 110; a mounting base 200 is mounted on the cylinder 110, and an insect inlet 103 is located on the periphery of the cylinder 110. Thus, the conical portion 120 facilitates the insertion of the grain storage pest trapping device 10 into the grain pile.

[0104] The cone 120 and the cylinder 110 can be detachably connected or fixedly connected. In this embodiment, considering that the application scenario of the grain storage pest trapping device 10 is mainly to be inserted into the grain pile, the connection method of the cone 120 and the cylinder 110 has little impact on the main performance of the grain storage pest trapping device 10. Of course, when it is necessary to clean the entire grain storage pest trapping device 10, the cone 120 and the cylinder 110 can be detachably connected, which makes cleaning the shell 100 simpler.

[0105] To prevent the grain pest trapping device 10 from being inserted too deeply into the grain pile, which could cause grain to enter the receiving cavity 102 from the insect inlet 201 on the mounting base 200 and fill the receiving cavity 102, thus preventing the grain pest trapping device 10 from working properly, in a preferred embodiment, the grain pest trapping device 10 includes an isolation member 700. The isolation member 700 is fixedly connected to the cylinder 110 near the opening 101, and the isolation member 700 is located below the insect inlet 201.

[0106] Understandably, when the grain pest trapping device 10 is inserted into the grain pile, the upper surface and above of the isolation member 700 are exposed outside the grain pile, while the lower surface of the isolation member 700 is usually in contact with the grain surface. This allows the grain pest trapping device 10 to be inserted deep enough into the grain pile, thereby increasing the coverage depth range of the grain pest trapping device 10. Additionally, crawling pests on the grain surface can also crawl in through the inlet 201. Of course, the lower surface of the isolation member 700 may also not be in contact with the grain surface.

[0107] The spacer 700 can be a one-piece molded plate with a third mounting through hole in the middle. The cylinder 110 passes through the third mounting through hole, so that the spacer 700 is fitted around the outer periphery of the cylinder 110. Alternatively, the spacer 700 can also consist of multiple spacer plates surrounding the cylinder 110.

[0108] For example, please refer to Figures 4 to 6 The isolating member 700 includes an isolating body 710 and a protrusion 720, with the protrusion 720 located on the side of the isolating body 710 near the cylinder 110. A first mounting through hole 114 is provided on the circumference of the upper end of the cylinder 110, and a second mounting through hole 721 is provided on the protrusion 720 corresponding to the position of the first mounting through hole 114. A screw or other connecting member 311 passes through both the first mounting through hole 114 and the second mounting through hole 721 simultaneously, thereby fixing the isolating member 700 onto the cylinder 110.

[0109] Preferably, to facilitate the installation of the isolating element 700 on the cylinder 110, the isolating body 710 is provided with a positioning part 730, and the upper end of the cylinder 110 is provided with a second mounting groove 113 for the positioning part 730 to engage. When the positioning part 730 engages with the second mounting groove 113, the first mounting through hole 114 and the second mounting through hole 721 are aligned and connected, thereby facilitating the simultaneous passage of screws or other connecting parts 311. Thus, by providing the positioning part 730 on the isolating body 710 and the second mounting groove 113 on the cylinder 110, the positioning and installation of the isolating element 700 is facilitated.

[0110] In another exemplary embodiment, please refer to Figure 3 , Figure 15 and Figure 16The cylinder 110 is engaged with the base 210. The upper end face of the cylinder 110 is open, and a first engaging portion 111 and a first mounting through hole 114 are formed at the opening 101. The first mounting through hole 114 typically communicates with a second mounting through hole 721. The base 210 is provided with a first slot 203 for engaging the first engaging portion 111. When the mounting base 200 is installed on the cylinder 110, the first engaging portion 111 engages with the first slot 203.

[0111] Specifically, the base 210 includes a first connecting cylinder 211, a second connecting cylinder 212, a first connecting portion 213, and a connecting rib 214; the first connecting cylinder 211, the first connecting portion 213, and the second connecting cylinder 212 form an annular groove 202; the connecting rib 214 is disposed within the annular groove 202, and both ends of the connecting rib 214 are respectively connected to the first connecting cylinder 211 and the first connecting portion 213, and there is a gap between the connecting rib 214 and the first connecting portion 213, thereby forming the first slot 203. When the mounting base 200 is installed on the cylinder 110, the connecting rib 214 is engaged in the first mounting slot 112.

[0112] Furthermore, in order to reduce the stress at the connection between the cylinder 110 and the base 210, the top surface of the protrusion 720 is flush with the top surface of the cylinder 110. The protrusion 720 is provided with a second locking part 722 corresponding to the position of the first locking part 111. When the mounting base 200 is installed on the cylinder 110, the first locking part 111 and the second locking part 722 are simultaneously engaged in the first locking groove 203, so that the second locking part 722 shares part of the stress on the first locking part 111.

[0113] In one exemplary embodiment, please refer to Figure 3 and Figure 7 The grain storage pest trapping device 10 includes a shell 100, a mounting base 200, an electrical control box 600, a lighting module 300, a camera component 500, and an insect collection component 400. The shell 100 includes a shell body and a conical portion 120. Typically, to facilitate insertion of the grain storage pest trapping device 10 into the grain pile, the shell body is usually cylindrical 110. The following description uses a cylindrical shell body 110 as an example.

[0114] Both ends of the cylinder 110 are open, and the cone 120 seals the bottom end of the cylinder 110. The tip of the cone 120 is positioned away from the cylinder 110 so as to facilitate the insertion of the grain storage pest trapping device 10 into the grain pile.

[0115] The mounting base 200 includes a base 210 and a support frame 220 mounted on the base 210. The base 210 is detachably mounted to the cylinder 110 at the opening 101 at its upper end. The detachability includes insertion, snap-fit, or threaded connection, etc.; the detachable mounting method has been described in detail above and will not be elaborated further here. The support frame 220 is located above the base 210. The support frame 220 includes a support part 221 and a second top plate 222 disposed above the support part 221. The support part 221 has an upwardly protruding fixing ring 223 formed on its top surface. The inner sidewall of the fixing ring 223 cooperates with the outer sidewall of the electrical control box 600.

[0116] The lighting module 300 includes a heat dissipation assembly 310 and a light source assembly 320. One end of the heat dissipation assembly 310 is fixedly connected to the second top plate 222, and the other end extends into the receiving cavity 102. The light source assembly 320 is installed on the heat dissipation assembly 310 and extends along the length of the housing 100. In this case, the heat dissipation assembly 310 not only dissipates heat but also serves as a connecting component. The heat dissipation assembly 310 includes a connector 311 and multiple heat sink groups 312 disposed on the outer periphery of the connector 311. One end of the connector 311 is connected to the second top plate 222, and the other end extends into the receiving cavity 102. The multiple heat sink groups 312 are arranged at intervals along the circumference of the connector 311 and extend along the length of the connector 311. A third mounting groove 301 is formed between two adjacent heat sink groups 312, and the light source assembly 320 is disposed within the third mounting groove 301.

[0117] The camera assembly 500 includes a storage box 510 and a camera 520. The storage box 510 includes a second base plate 511 and an upper cover 512 covering the second base plate 511. The camera 520 is typically mounted on the second base plate 511 and then covered by the upper cover 512. The storage box 510 is mounted on the connector 311. Thus, the storage box 510 is directly mounted to the connector 311, and the heat generated by the camera 520 can be dissipated through the heat dissipation assembly 310. In addition, since the connector 311 is hollow, the connection point between the camera 520 and the control unit inside the electrical control box 600 can be directly through the connector 311, thereby hiding the wiring of the camera 520 and the control unit, thus optimizing the internal structure of the grain warehouse pest trapping device 10 to a certain extent.

[0118] The insect collection assembly 400 includes a mounting bracket 420 and an insect collection chamber 410 mounted on the mounting bracket 420. The mounting bracket 420 is connected to a storage box 510. The inlet of the insect collection chamber 410 is arranged facing upward so that the insect collection chamber 410 can receive pests entering through the insect inlet 201 or the insect inlet hole 103.

[0119] In this embodiment, by mounting the electrical control box 600, the light module 300, the camera component 500, and the insect collection component 400 on the mounting base 200, and the mounting base 200 being detachably connected to the housing 100, when the opening 101 at the upper end of the housing 100 is large, it is not necessary to remove the entire device from the grain pile when it is necessary to clean pests or when the electrical control box 600 and the camera 520 need to be repaired. This improves the efficiency of cleaning pests inside the trapping device and the maintenance efficiency of the electrical control box 600 and the camera 520.

[0120] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
