[0035] A device for monitoring and trapping pests inside a grain pile, which is suitable for being inserted into a grain pile to trap pests in the grain pile, such as Figures 1 to 9 As shown, it includes: an insect attractant rod 100, an insect attractant bin 200, a fixing assembly 300 and a camera device 410; the insect attractant rod 100 is provided with a cavity with openings at both ends, and more than two insect attractant holes 110 are provided on the outer wall, the insect attractant bin 200 and the fixing assembly 300 are respectively arranged at opposite ends of the insect attractant rod 100; the fixing assembly 300 is suitable for sealing the open end of the insect attractant rod 100; the interior of the cavity of the insect attractant bin 200 is suitable for placing insect attractants, and an isolation net 120 is provided at one end of the insect attractant bin 200 close to the insect attractant rod 100, and the internal cavity of the insect attractant bin 200 is connected with the internal cavity of the insect attractant rod 100 through the isolation net 120; a fixing ring 210 is provided at one end of the insect attractant bin 200 away from the insect attractant rod, and the camera device 410 is installed in the cavity of the insect attractant rod 100 through a fixing frame 411 and is located at one end close to the insect attractant bin 200.

[0036] It should be noted here that the insect trap rod 100 of the pest monitoring and trapping device inside the grain pile of the present application can be inserted into the grain pile to a depth of 1-10 meters and the fixing component 300 is located outside the grain pile, so that the part of the present application located inside the grain pile can be easily removed from or inserted into the grain pile; Figure 1 , Figure 2As shown, the insect attractant rod 100 is suitable for providing necessary structural support for the overall structure. The cavity design of the insect attractant rod 100 with openings at both ends is suitable for providing space for collecting pests. The insect attractant bin 200 and the fixing assembly 300 are detachably mounted at both ends of the insect attractant rod 100, thereby preventing the pests entering the insect attractant rod 100 from escaping from both ends, and also preventing the grain in the granary from entering the cavity of the insect attractant rod 100 from both ends of the insect attractant rod 100. The outer wall of the insect attractant rod 100 is provided with insect attractant holes that allow pests to enter the cavity of the insect attractant rod 100. 110, at the same time, the insect-attracting holes 110 help to maintain air circulation in the inner cavity of the insect-attracting rod 100, and the isolation net 120 allows the attractive odor released by the insect attractant to enter the cavity of the insect-attracting rod 100 through its mesh holes, but prevents pests from entering the cavity of the insect-attracting agent bin 200. After smelling the odor released by the insect attractant, the pests are attracted to enter the cavity of the insect-attracting rod 100 through the insect-attracting holes 110, but cannot contact the insect attractant, thereby preventing the insect attractant from being eaten or contaminated by pests, extending the use time of the insect attractant, and improving the insect-attracting effect. The fixing ring 210 is suitable for fixing the insect attractant bin 200 and the insect attractant rod in the position to be installed. The design of the fixing ring 210 allows the use of auxiliary devices (such as hooks, clips, etc.) to easily hook and fix the insect attractant bin 200, thereby conveniently inserting the entire device into the grain, improving the convenience and efficiency of operation.

[0037] like Figure 2 , Figure 6 As shown, the camera device 410 is suitable for monitoring the pests in the cavity of the insect attractant rod 100. By setting up the camera device 410, the behavior, type and quantity changes of the pests in the granary can be observed more directly. Compared with the traditional manual monitoring method, the camera device 410 reduces the dependence on manual labor, avoids monitoring errors caused by human factors, and improves monitoring efficiency and accuracy.

[0038] Further, such as Figure 6 , Figure 7 As shown, the main body of the fixing frame 411 is a rod-shaped structure, and more than two fixing frames 411 are provided, which are suitable for providing stable support for the camera device 410. The more than two fixing frames 411 are arranged equidistantly along the circumference of the insect attractant rod 100, and the two ends of each fixing frame 411 are fixedly connected to the camera device 410 and the inner side wall of the insect attractant rod 100, respectively, and the body length direction of the fixing frame 411 is perpendicular to the body length direction of the camera device 410.

[0039] In one possible implementation, Figures 1 to 3As shown, the insect attracting rod 100 is provided with a connecting portion 111; the connecting portion 111 is located between the insect attracting rod 100 and the insect attractant chamber 200, and the internal cavity of the connecting portion 111 is communicated with the internal cavity of the insect attracting rod 100, the main body of the connecting portion 111 is a tubular structure, the connecting portion 111 is provided with a cavity with two ends opened, and the camera device 410 is installed in the cavity of the connecting portion 111 through a fixing frame 411. By providing the connecting portion 111, when the camera device 410 needs to be maintained or replaced, the staff can easily disassemble or reinstall the connecting portion 111 without disassembling other components too much.

[0040] In one possible implementation, Figures 1 to 4 As shown, the apparatus further includes a pest collection chamber 130, which is disposed between the insect attractant chamber 200 and the insect attractant rod 100, and the inner cavity of the pest collection chamber 130 is communicated with the inner cavity of the insect attractant rod 100, and the pest collection chamber 130 is suitable for collecting pests that enter the insect attractant rod 100. By providing the pest collection chamber 130, it is prevented that pests move arbitrarily in the cavity of the insect attractant rod 100 and affect the monitoring results, thereby ensuring that the attracted pests are effectively collected and improving the monitoring efficiency.

[0041] Furthermore, the length of the pest collection chamber 130 ranges from 30 mm to 50 mm. Preferably, the length of the pest collection chamber 130 is 30 mm.

[0042] In summary, the insect attractant chamber 200, the pest collection chamber 130, the connecting portion 111 and the insect attractant rod 110 are connected in sequence. Figures 2 to 4 , Figure 8As shown, the insect attractant bin 200 is provided with a cavity with an opening at one end, the opening end of the insect attractant bin 200 is detachably connected to the pest collecting bin 130, the isolation net 120 is placed at the opening end of the insect attractant bin 200, and the inner wall of the pest collecting bin 130 is symmetrically provided with fixing bolts 131. When the insect attractant bin 200 is connected to the pest collecting bin 130, the fixing bolts 131 abut against the isolation net 120, and the fixing bolts 131 are located on the side of the isolation net 120 away from the insect attractant bin 200, thereby fixing the isolation net 120 at the opening of the insect attractant bin 200, ensuring that the isolation net 120 will not shift or fall off during the process of attracting and collecting pests. The insect attractant bin 200 is threadedly connected to the pest collecting bin 130, that is, a threaded structure is provided at the open end of the insect attractant bin, and an internal thread is provided on the inner wall of the pest collecting bin 130 away from the connecting portion 111. The threaded structure of the insect attractant bin 200 and the internal thread of the pest collecting bin 130 are engaged with each other to achieve a threaded connection between the two. The design of the threaded connection between the insect attractant bin 200 and the pest collecting bin 130 ensures that the insect attractant bin 200 is not easy to loosen or fall off during use. When the insect attractant needs to be replaced or filled, the insect attractant bin 200 can be separated from the insect attractant rod 100 and reinstalled by rotating it.

[0043] like Figure 3 As shown, the pest collecting bin 130 is threadedly connected to the connecting portion 111, that is, a threaded structure is provided at one end of the pest collecting bin 130 connected to the connecting portion 111, and correspondingly, an internal thread is provided on the inner side wall of the end of the connecting portion 111 away from the insect attractant rod 100, and the threaded structure of the pest collecting bin 130 and the internal thread of the end of the connecting portion 111 away from the insect attractant rod 100 are meshed with each other, so that the two can be tightly combined to prevent pests from escaping from the connection between the pest collecting bin 130 and the connecting portion 111 during the collection process. At the same time, the threaded connection also makes it easy to disassemble the pest collecting bin 130 when it needs to be cleaned.

[0044] Further, such as Figure 3 As shown, the insect attractant rod 100 is threadedly connected to the connecting portion 111, that is, one end of the insect attractant rod 100 connected to the connecting portion 111 is provided with a threaded structure, and correspondingly, a matching internal thread is provided on the inner side wall of the connecting portion 111. By rotating the connecting portion 111, the threaded structure of the insect attractant rod 100 and the internal thread on the inner side wall of the connecting portion 111 engage with each other, thereby achieving a fixed connection between the two. When the camera device 410 needs to be maintained or replaced, the staff can easily disassemble or reinstall the connecting portion 111 without disassembling other components too much.

[0045] In one possible implementation, Figure 4 , Figure 5 , Figure 8As shown, the main body of the insect attractant bin 200 is a conical structure, and the fixing ring 210 is arranged at the top of the conical structure. It should be noted here that the design of the conical structure can reduce the friction resistance between the insect attractant bin 200 and the food. Figure 4 , Figure 5 As shown, a fixing sealing hole 211 is opened at the top of the fixing ring 210, one end of the fixing ring 210 is inserted into the fixing sealing hole 211 from the top of the insect attractant chamber 200, and epoxy resin is poured into the fixing sealing hole 211 to fix the fixing ring 210 in the sealing fixing hole, thereby preventing the fixing ring 210 from falling off during use and preventing the insect attractant from leaking. Preferably, the fixing ring 210 is made of a 3MM steel wire rope crimped with an aluminum ring.

[0046] Furthermore, the insect attractants are mixed with solid particles, powders, and liquid insect attractants according to the types of grains.

[0047] In one possible implementation, the camera device 410 uses a JH-3000 full-color night vision high-definition camera model in the prior art.

[0048] In one possible implementation, Figure 1 As shown, more than two insect-attracting holes 110 are arranged in an array on the outer wall of the insect-attracting rod 100. It should be noted here that by arranging more than two insect-attracting holes 110 in an array on the outer wall of the insect-attracting rod 100, the coverage of the odor released by the insect attractant can be expanded, and the insect-attracting efficiency can be improved. The equidistantly arranged insect-attracting holes 110 help to achieve a balanced distribution of the insect attractant in the granary, avoiding the situation where the concentration of the insect attractant is too high in some areas and too low in other areas, thereby improving the overall insect-attracting effect.

[0049] Preferably, the diameter of the insect-attracting holes is 3 mm, and the distance between two adjacent insect-attracting holes is 20 mm.

[0050] In one possible implementation, Figure 2 , Fig. 9 As shown, a monitoring device is also included. The monitoring device is arranged inside the cavity of the insect attractant rod 100 and is suitable for monitoring the environment in the granary. By installing the monitoring device in the cavity of the insect attractant rod 100, it can be closer to the actual environment of grain storage, thereby obtaining more accurate environmental parameter data.

[0051] Furthermore, the detection device includes a temperature and humidity sensor 420, which is disposed inside the cavity of the insect attractant rod 100 and is suitable for detecting the temperature and humidity in the granary. The temperature and humidity sensor 420 monitors the temperature and humidity in the granary, and the management personnel can timely discover potential problems caused by abnormal temperature and humidity in the granary, reduce damage to grain, and improve storage safety.

[0052] Furthermore, the detection device includes a gas sensor 430, which is arranged inside the cavity of the insect attractant rod 100 and is suitable for detecting the gas concentration in the granary. By monitoring the oxygen content and carbon dioxide content of the air in the granary through the gas sensor 430, the management personnel can timely discover potential problems caused by insufficient oxygen or excessive carbon dioxide concentration in the granary, thereby improving the safety of storage.

[0053] By monitoring these key environmental parameters through the temperature and humidity sensor 420 and the gas sensor 430, managers can use the acquired monitoring data to guide the ventilation, temperature control, humidity control and other operations of the granary to optimize the storage environment and extend the shelf life of the grain.

[0054] Preferably, the temperature and humidity sensor 420 adopts the model sht30 in the prior art, and the gas sensor 430 adopts the model JH-Sen-O2 in the prior art.

[0055] In one possible implementation, a processor 440 is also included; one end of the processor 440 is inserted into the fixing assembly 300, and the other end of the processor 440 is inserted into the cavity of the insect attractant rod 100, and the temperature and humidity sensor 420 and the gas sensor 430 are both arranged at the end of the processor 440 that is inserted into the insect attractant rod 100; the signal output end of the camera device 410, the signal output end of the temperature and humidity sensor 420, and the signal output end of the gas sensor 430 are all electrically connected to the signal input end of the processor 440.

[0056] It should be noted here that if Figure 2 , Fig. 9 As shown, the temperature and humidity sensor 420 and the gas sensor 430 are integrated in one end of the processor 440 that is inserted into the cavity of the insect attracting rod 100. The signal output end of the camera device 410 is connected to the signal input end of the processor 440 through the transmission line 520. By integrating the monitoring device on the processor 440, the need for wiring between the monitoring device and the processor 440 is reduced, so that the overall structure is more compact and easy to install in a limited space. At the same time, the integrated design can reduce interference and attenuation in the signal transmission process, improve the accuracy and efficiency of data transmission, and the camera device 4 10. The temperature and humidity sensor 420 and the gas sensor 430 transmit the monitored data to the processor 440, and the processor 440 uploads the received monitoring data to the host computer, so that the staff can provide data support for subsequent comprehensive analysis and processing. The monitoring device and the camera device 410 are arranged in the cavity of the insect attractant rod 100 and are located at both ends of the insect attractant rod 100. This design method prevents interference between the monitoring device and the camera device 410, and can collect different data at the same time, thereby realizing multi-dimensional and all-round monitoring of the granary and improving the efficiency and accuracy of monitoring.

[0057] Furthermore, the processor 440 is provided with a network port 450, which is suitable for connecting the processor 440 to an external device, so that the processor 440 can efficiently and accurately transmit the received detection data to the external device through the network port, thereby improving the data transmission efficiency.

[0058] Preferably, the processor 440 adopts the existing technology model: mt7628n.

[0059] In a possible implementation, the fixing assembly 300 includes a fixing sleeve rod 310 and a hollow nut 320; the fixing sleeve rod 310 is provided with a cavity with two ends opened, and the two ends of the fixing sleeve rod 310 are respectively connected to the hollow nut 320 and the insect attractant rod 100.

[0060] It should be noted here that if Figure 2 , Fig. 9 As shown, one end of the processor 440 is arranged in the cavity of the fixed sleeve rod 310 and is provided with a monitoring device, one end of which probes into the cavity of the insect attracting rod 100. The outer side walls of both ends of the fixed sleeve rod 310 are provided with external threads, and the inner side wall of the insect attracting rod 100 is provided with internal threads matching the external threads. The fixed sleeve rod 310 is threadedly connected with the insect attracting rod 100 so that the end of the processor 440 provided with the monitoring device is installed in the cavity of the insect attracting rod 100. When the monitoring device needs maintenance or the external device is connected to the network port 450 on the processor 440, the staff can easily disassemble or reinstall the fixed sleeve rod 310 without excessively disassembling other parts. The inner side wall of the hollow nut 320 is provided with an internal thread matching the external thread of the fixed sleeve rod 310. The fixed sleeve rod 310 is threadedly connected with the hollow nut 320. The hollow nut 320 is suitable for providing a channel for the processor 440 in the fixed sleeve rod 310 to be physically connected to the external device.

[0061] Further, such as Figure 2 , Fig. 9 As shown, it also includes a transmission line protection tube 510, which passes through the hollow nut 320 and is inserted into the cavity of the fixed sleeve rod 310. The connecting wire of the processor 440 is suitable for passing through the inner cavity of the transmission line protection tube 510 to be electrically connected to the external device. The transmission line protection tube 510 provides a physical protection barrier for the connecting wire to prevent it from being directly impacted, worn or cut by the external environment, thereby extending the service life of the connecting wire. The processor 440 is connected to the external host computer through the connecting wire in the transmission line protection tube 510, thereby ensuring that the processor 440 can promptly send the received monitoring data to the host computer through the connecting wire, and the user can view the detailed environmental data and pest conditions in the granary through the host computer.

[0062] In one possible implementation, Fig. 9As shown, it also includes a gripping portion 330; the gripping portion 330 is arranged on the outer side wall of the fixed sleeve rod 310. It should be noted here that the main body of the gripping portion 330 is a U-shaped structure with an opening facing the fixed sleeve rod 310, and a fixing ear 340 is arranged on the outer side wall of the fixed sleeve rod 310. The two ends of the opening of the gripping portion 330 penetrate the fixing ear 340 and are fixedly connected to the limit block 350. When it is necessary to take the monitoring device out of the granary, the monitoring device can be taken out of the granary by simply pulling the gripping portion 330.
