Description

Technical Field

[0001] This utility model relates to the field of grain storage pest detection technology, specifically a novel pest detection box. Background Technology

[0002] Grain reserves are a crucial foundation for national development, making the safety of grain storage extremely important. During storage, grain needs to be sampled and tested regularly to determine its condition within the granary, enabling timely measures to be taken to ensure its safe storage.

[0003] During sampling and testing, it is necessary not only to determine whether the grain has become moldy, but also to detect pests. Pests not only affect the quality of grain, but also render large quantities of grain unusable. Every year, pests cause grain losses of 10% to 15% during storage.

[0004] Currently, after extracting grain samples, pest detection is usually carried out through manual screening, which is not only time-consuming and labor-intensive, but also inefficient and requires a lot of manpower. Utility Model Content

[0005] To address the technical problems existing in the background art described above, this utility model provides a novel insect detection box.

[0006] The technical solution of this utility model is as follows:

[0007] A novel insect detection box includes a box body and a box lid;

[0008] The box contains an insect-attracting box and a partition surrounding the insect-attracting box, with a distance between the partition and the insect-attracting box and the side wall of the box.

[0009] The insect-attracting box has an insect inlet hole on its side wall, an insect-attracting lamp on the inner side of its top wall, and a motor on its outer side. The motor output shaft extends upward and is connected to an umbrella-shaped insect filter plate. The insect filter plate has insect filter holes, and the outer edge of the insect filter plate is vertically aligned with the partition.

[0010] A photoelectric counter is installed inside the insect-attracting box at the position corresponding to the insect inlet hole;

[0011] The top wall of the box lid has a feed inlet above the filter plate. A conical feed baffle extends downward from the edge of the feed inlet. The inner conical surface of the baffle and the outer conical surface of the filter plate work together to form a feed channel for filtering insects. A feed hopper extends upward from the edge of the feed inlet.

[0012] In operation, the motor drives the filter plate to rotate, and the sample grain is poured into the feed hopper. The grain enters the filter channel, and due to the weight difference between the grain and the pests, different centrifugal forces are generated under the rotation of the filter plate, thus separating the grain and the pests. The grain falls along the filter channel to the outside of the partition, while the pests slide on the surface of the filter plate and fall through the filter holes to the inside of the partition. Attracted by the insect-attracting lamp, the pests enter the insect-attracting box through the inlet hole. The number of pests entering is recorded by a photoelectric counter.

[0013] The pest detection box of this application only requires pouring the sample grain into the grain hopper. The pest detection box automatically obtains the number of pests through operation, eliminating the need for manual screening, saving manpower, reducing the labor intensity of personnel, and multiple pest detection boxes can be used at the same time to improve detection efficiency.

[0014] To improve the smooth passage of grain through the filter insect channel, several circumferentially evenly arranged rotating grain strips are provided on the outer conical surface of the filter plate. The rotating grain strips extend downwards in an arc shape from the top of the filter plate, and the arc direction of several rotating grain strips is the same. When the filter plate rotates, the direction is opposite to the curvature direction of the rotating grain strips. Through the rotating and pushing action of the grain strips, the grain moves from top to bottom along the filter insect channel.

[0015] Furthermore, the filter holes are horizontal annular fine strip holes, and several of them are provided on the filter plate, arranged vertically, in order to improve the interception and filtration effect of pests.

[0016] Furthermore, the outer conical surface of the filter plate is provided with insect-blocking ridges at the lower edge of the filter holes, and the protrusion height of the insect-blocking ridges is less than that of the grain rotating strips. The insect-blocking ridges not only improve the interception effect of pests, but also cause the grain to bounce during movement, further improving the separation effect between the grain and pests.

[0017] Furthermore, the outer conical surface of the filter plate descends in a stepped manner. When the grain moves through the filter plate, the stepped design creates a drop in the outer conical surface, causing the grain to collide as it moves from one step to the next, further improving the separation effect between pests and grain.

[0018] Preferably, along the direction of the generatrix of the filter plate, the length of each step on the outer conical surface of the filter plate increases sequentially from top to bottom.

[0019] In some embodiments, a conical dust baffle is fixed to the top of the insect trap box. The center of the dust baffle is rotatably connected to the motor output shaft, and the outer edge extends out of the side wall of the insect trap box. This not only concentrates the filtered pests between the partition and the insect trap box, but also prevents pests and dust from blocking the insect inlet.

[0020] In some embodiments, a mounting groove is provided at the center of the bottom wall of the box, and the insect-attracting box is detachably fixed in the mounting groove to facilitate the removal of the insect-attracting box and the cleaning of the collected pests.

[0021] Preferably, the insect-attracting box is cup-shaped and inverted in the mounting groove, with the insect inlet hole flush with the top surface of the bottom wall of the box, which makes it easier for pests to enter the insect-attracting box. At the same time, the mounting groove has a certain depth, which is conducive to collecting pests and preventing pests from crawling out.

[0022] In some embodiments, the lid height is adjustable to adjust the gap between the grain baffle and the insect filter, thereby enabling the insect detection box to perform insect detection operations on grains of different sizes.

[0023] This utility model provides a novel insect detection box that separates and filters grain and pests in a sample using a rotating filter plate. Then, an insect-attracting lamp lures pests through an inlet hole, and a photoelectric counter records the number of pests that pass through. Combined with the sample weight, the insect infestation status of the grain in the granary is analyzed. This process eliminates the need for manual screening, reducing labor intensity. Furthermore, a single person can operate multiple detection boxes simultaneously to inspect multiple samples, saving manpower and improving detection efficiency. Attached Figure Description

[0033] Example 1

[0034] like Figure 1 As shown, this utility model embodiment provides a novel insect detection box, including a box body 1 and a box cover 2, with the box cover 2 fastened onto the box body 1.

[0035] The box 1 contains an insect-attracting box 3 and a partition 4 surrounding the insect-attracting box 3. The partition 4 is spaced apart from both the insect-attracting box 3 and the side wall of the box 1. The insect-attracting box 3 has an insect-entry hole 31 on its side wall and an insect-attracting lamp 32 on its inner top wall, with the light from the lamp shining through the insect-entry hole 31. A photoelectric counter 33 is located inside the insect-attracting box 3 corresponding to the position of the insect-entry hole 31.

[0036] The top wall of the insect-attracting box 3 is equipped with a motor 5. The output shaft of the motor 5 extends upward and is connected to an umbrella-shaped insect-filtering plate 6. The insect-filtering plate 6 has multiple insect-filtering holes 61, and the outer edge of the insect-filtering plate 6 is vertically aligned with the partition 4.

[0037] The top wall of the box cover 2 is provided with a grain inlet 21 above the filter plate 6. A conical grain baffle 22 extends downward from the edge of the grain inlet 21. Its inner conical surface cooperates with the outer conical surface of the filter plate 6 to form a grain filtering channel. A grain hopper 23 extends upward from the edge of the grain inlet 21.

[0038] In this embodiment, the insect detection box is used such that the motor 5 drives the filter plate 6 to rotate, and the sample grain is poured into the grain inlet hopper 23. The grain enters the insect filtering channel. Under the rotation of the filter plate 6, due to the different weights of the grain and the pests, they generate different centrifugal forces, thus separating the grain and the pests. The grain falls along the insect filtering channel to the outside of the partition 4, while the pests slide on the surface of the filter plate 6 and fall into the inside of the partition 4 through the filter holes 61. Attracted by the insect-attracting lamp 32, the pests enter the insect-attracting box 3 through the insect inlet 31. When the pests enter, the number of pests entering is recorded by the photoelectric counter 33. The quantity information obtained by the photoelectric counter can be sent to a terminal device (not shown in the figure) for display.

[0039] During the insect inspection process, only manual pouring of sample grains and starting of motor 5 are required, without any other operations. This reduces labor intensity and allows a single person to operate multiple insect inspection boxes to inspect multiple samples simultaneously, saving manpower and improving detection efficiency.

[0040] In detail, the insect-detecting box provided in this embodiment is preferably cylindrical, with the lid 2 threadedly connected to the box body 1, so that the height of the lid 2 is adjustable, thereby adjusting the gap between the grain baffle 22 and the insect filter plate 6, so that the insect-detecting box can perform insect detection operations on grains of different particle sizes, such as corn, soybeans, rice, etc.

[0041] The gap between the grain-blocking plate 22 and the insect-filtering plate 6 should ideally be 1-1.5 times the size of the grain particles.

[0042] The bottom wall of the box 1 has an installation groove at its center. The insect-attracting box 3 is inserted into the installation groove and is detachably fixed to the bottom wall of the box 1 to facilitate the removal of the insect-attracting box 3 and the cleaning of the collected pests.

[0043] In addition, the bottom wall of the box body 1 is provided with an annular groove corresponding to the position of the partition 4, which is inserted and matched with the partition 4 to fix the partition 4, and at the same time, the partition 4 can be removed to facilitate cleaning of the insect detection box.

[0044] The insect-attracting box 3 is preferably cup-shaped and inverted in the mounting groove, so that the bottom surface of the mounting groove serves as the bottom surface of the internal space of the insect-attracting box 3. The mounting groove has a certain depth, which is beneficial for collecting pests and preventing them from crawling out. In addition, the inner side wall of the insect-attracting box 3 can be machined into a smooth surface that prevents pests from climbing or coated with a smooth coating that prevents pests from climbing.

[0045] The partition 4 is preferably circular and coaxial with the insect-attracting box 3.

[0046] The insect inlet 31 of the insect-attracting box 3 is preferably positioned flush with the top surface of the bottom wall of the box body 1 to facilitate the entry of pests into the insect-attracting box 3. The width of the insect inlet 31 is preferably set to allow only a single pest to enter. There are multiple insect inlet 31s, evenly distributed along the circumference of the side wall of the insect-attracting box 3. Multiple photoelectric counters 33 are provided, corresponding one-to-one with the insect inlet 31s, and are positioned above the insect inlet 31s.

[0047] In addition to the insect-attracting lamp 32, a camera 34 is also installed on the inner side of the top wall of the insect-attracting box 3. A wireless terminal is installed outside the insect-attracting box, which communicates with the camera 34. The camera 34 captures images of the bottom of the insect-attracting box 3 and transmits them to the wireless terminal. The wireless terminal processes the images, analyzes the number of pests, checks and corrects them with the photoelectric counter 33, and analyzes the types of pests to more accurately analyze the condition of the grain stored in the grain warehouse, so as to carry out targeted pest control.

[0048] In addition to the motor 5, the top of the insect trap 3 is also fixed with a conical dust baffle 7. The dust baffle 7 covers the motor 5, and its center is rotatably connected to the output shaft of the motor 5. Its outer edge extends out of the side wall of the insect trap 3. It can not only concentrate the filtered pests between the partition 4 and the insect trap 3, but also prevent pests and dust from falling to the position near the insect inlet 31 and blocking the insect inlet 31.

[0049] Combined Figure 2 As shown, the outer conical surface of the filter plate 6 is provided with several circumferentially evenly arranged grain-rotating strips 62. The grain-rotating strips 62 extend downward in an arc shape from the top of the filter plate 6, and the arc direction of the several grain-rotating strips 62 is the same. When the filter plate 6 rotates, the direction is opposite to the curvature direction of the grain-rotating strips 62. Through the rotating and pushing action of the grain-rotating strips 62, the grain moves from top to bottom along the filter grain channel, thereby improving the smoothness of the grain passing through the filter grain channel and ensuring the grain intake, and avoiding blockage at the grain inlet 21.

[0050] The filter holes 61 are horizontal annular fine strip holes, and several are arranged vertically on the filter plate 6 to improve the interception and filtration effect of pests. The pore size of the filter holes 61 is smaller than the size of the sample grain particles but larger than the size of the pests.

[0051] The outer conical surface of the filter plate 6 is also provided with an insect-blocking ridge 63 at the lower edge of the filter hole 61, such as... Figure 1 As shown, the protrusion height of the insect-blocking ridge 63 is less than that of the grain-rotating strip 62, and less than 1 / 3 of the sample grain particle size. The insect-blocking ridge 63 not only improves the interception effect of pests, but also causes the grain to bounce during movement, further improving the separation effect between the grain and pests.

[0052] Furthermore, the outer conical surface of the filter plate 6 is configured to descend in a stepped manner, such as... Figure 1 As shown, when the grain moves in the insect-filtering channel, the stepped design creates a drop on the outer conical surface of the insect-filtering plate 6. When the grain moves from one step to the next, it will collide, further improving the separation effect between pests and grain.

[0053] Preferably, along the direction of the generatrix of the filter plate 6, the length of each step on the outer conical surface of the filter plate 6 increases sequentially from top to bottom, in order to address the problem that the grain moves faster closer to the outer edge of the filter plate 6.

[0054] Example 2

[0055] like Figure 3 and Figure 4As shown, the insect-detecting box provided in this embodiment has a structure basically the same as that in Embodiment 1. The difference is that a connecting part 64 extends downward from the center of the inner side of the filter plate 6. The connecting part 64 is provided with a spline groove (not shown in the figure), and the output shaft of the motor 5 is provided with a spline (not shown in the figure) that mates with the spline groove. The connecting part 64 and the output shaft of the motor 5 are axially slidably connected through the engagement of the spline and the spline groove. A first toothed disc 81 is fixed on the connecting part 64, and a second toothed disc 82 is fixed on the dust baffle plate 7. The two toothed discs are coaxial with the output shaft of the motor 5. Several teeth 83 that mate with each other are provided on the opposite surfaces of the two toothed discs. The teeth 83 are arranged in a ring evenly around the central axis of the toothed discs. The teeth 83 are ratchet-shaped, such as... Figure 5 As shown, when the two toothed discs are joined together, the inclined surfaces of their protruding teeth 83 abut against each other. When the filter plate 6 rotates, the first toothed disc 81 is first lifted by the second toothed disc 82 and then falls down instantly. This process repeats, causing the filter plate 6 to vibrate while rotating. This not only facilitates the entry of the sample grain into the filter grain channel but also helps to separate pests from the grain.

[0056] Example 3

[0057] like Figure 6 As shown, the insect-detecting box in this embodiment has a structure basically the same as that in Embodiment 2. The difference is that the lid 2 is fastened to the box body 1 and can slide vertically. The sliding surfaces between the lid 2 and the box body 1 are preferably not tightly fitted to ensure the sliding freedom of the lid 2. A tripod 231 is fixed in the grain inlet hopper 23. A push rod 65 protrudes upward from the top center of the insect-filtering plate 6. The top of the push rod 65 is rotatably connected to the center of the tripod 231. It is configured so that when the insect-filtering plate 6 vibrates up and down with the cooperation of the two toothed discs, the push rod 65 pushes the tripod 231, thereby causing the lid 2 to vibrate up and down, further improving the separation effect of grain and pests. At the same time, the vibration makes it easier for grain and pests to enter the insect-filtering channel and be filtered.

[0058] When the filter plate 6 rotates, the lid 2 will not rotate with it. To further ensure that the lid 2 will not rotate with the filter plate 6, a vertical groove (not shown in the figure) is provided on the outer side wall of the box body 1, and a sliding strip (not shown in the figure) is provided on the inner side wall of the lid 2 to slide in conjunction with the groove. This serves as a limit, restricting the lid 2 to slide vertically and not rotate.

[0059] In addition, to ensure the smooth up-and-down vibration of the lid 2, pressure equalization vents 24 are provided on the top wall of the lid 2 to prevent negative pressure from being generated inside the insect detection box, which would affect the vibration of the lid 2.

[0060] In this embodiment, the motor 5 can be a high-power motor 5, and the two toothed plates can be made of high-strength and wear-resistant materials such as steel to support the simultaneous vibration of the filter plate 6 and the box cover 2. Alternatively, the box cover 2 and the filter plate 6 can be made of materials such as low-density resin or polyethylene to reduce the load requirements on the motor 5 and the toothed plates.
