Description

Technical Field

[0001] The present invention relates to the technical field of insect detection and forecasting, and in particular to an insect trapping and photographing device and method. Background Art

[0002] At present, insect pests in my country's agricultural production process are relatively serious, causing significant economic losses every year. The Chinese government, forestry departments and farmers invest a lot of manpower, material resources and financial resources every year to prevent and control these pests. At present, the use of insect sex attractants combined with trap pots or trap bottles in the collection container plays an active role in the monitoring and prevention of pests. Therefore, trapping devices for trapping pests are usually placed in the field to trap pests.

[0003] The prior art discloses a Chinese patent with publication number CN 108770799 B: an insect trapping and photographing device, and discloses a photographing device and an insect killing device, which photographs and collects the external appearance of insects flying towards sexual attractants using a photographing device, and at the same time, kills the insects using an electrified metal wire mesh.

[0004] However, the above-mentioned prior art still has certain defects. That is, during use, a camera is used to photograph flying living insects, which may easily lead to misjudgment of the insect species due to incomplete collection of the insect's external morphology, affecting the subsequent targeted treatment of pests. At the same time, directly using an electrified metal wire mesh to kill insects may easily cause external damage to the insect's morphology, which is also not conducive to the subsequent analysis and judgment of the insect species.

[0026] The present invention also provides a method for trapping insects using the above-mentioned insect trapping and photographing device, which specifically includes the following operating steps:

[0027] S1. Attract insects: After installing the device and turning on the power supply, turn on the control switch of the lamp tube to make the lamp tube emit light to attract insects to approach.

[0028] S2. Freezing treatment: After the infrared detector detects that an insect has entered the capture area, start Motor 1 to drive the impeller to rotate, and let the wind blown by the rotating impeller pass through the orifice plate to blow the insects entering the capture area downward, so that the insects enter the inside of the exchange cylinder under the guidance of the guiding frame. Then, drive the exchange cylinder by Motor 2 to send the insects to the area where the semiconductor refrigeration sheet is located, and use the low-temperature environment at the cold end of the semiconductor refrigeration sheet to perform low-temperature treatment on the insects, so that the insects are no longer active but remain alive.

[0029] S. Insect cleaning: a. Use Motor 2 to drive the exchange cylinder to continue rotating, so that the insects after low-temperature treatment fall to the top of the swing plate and slide down along the swing plate to different areas at the high-position end of the top of the folding plate. Then, the corresponding Cylinder 1 pushes the insects that are no longer active after low-temperature treatment out of the area where they are located and falls through the leakage hole to the top of the receiving plate.

[0030] b. Use Motor 4 to drive the gear to rotate, and use the rotating gear to drive the arc-shaped tooth plate to rotate. At the same time, cooperate with Motor 3 to drive the limiting frame to rotate, and use the two cameras inside the arc-shaped tooth plate to take multi-angle photos of the insects on the receiving plate.

[0031] c. After the insects are photographed, use Motor 5 to drive the receiving plate to flip 180°, so that the photographed insects fall into the inside of the support, and the buckling state of the buckling mechanism is released irregularly to pour out the insects collected inside the support.

[0032] Advantages of the present invention:

[0033] 1. The present invention effectively avoids damaging the killed insects and affecting the relevant data analysis of subsequent trapped insects by using the airflow blown by the rotating impeller to send the insects entering the capture area into the freezing area and using the low-temperature environment created by the cold end of the semiconductor refrigeration sheet to perform low-temperature treatment on the insects entering this area, so that the insects are no longer active.

[0034] 2. The present invention drives the swing assembly by using the rotating exchange cylinder to make the swing plate swing downward, so that the low-position end of the swing plate in the initial state sinks downward, forming a pre-support area between the downward-swinging swing plate and the baffle. The insects are evenly distributed at the bottom end of the swing plate under the block of the baffle, and the reset swing plate lifts the evenly distributed insects upward, so that the evenly distributed insects fall into the small area at the corresponding position, which is convenient for subsequent taking photos of the insects after low-temperature treatment one by one.

[0035] 3. The present invention drives the arc-shaped tooth plate to rotate by using a rotating gear, and at the same time, the rotation of the limiting frame is assisted to achieve multi-directional shooting of insects that are no longer active after low-temperature treatment, so as to better judge the types of trapped insects, thereby laying a foundation for subsequent effective pest control.

[0036] 4. The present invention uses a fastening mechanism to dock and fasten the support base and the housing cover, without the need to operate with the aid of other external tools, and the disassembly and assembly are convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0053] The insect trapping and photographing device of the present invention belongs to a kind of graphic image output device and is a part of the Internet of Things technology. It is mainly used for insect forecasting, attracting insects, subjecting them to low-temperature treatment to make the insects inactive, and multi-directionally collecting the external forms of the insects that are inactive due to cold, providing a theoretical basis for subsequent pest control.

[0054] Example 1: Refer to the attached drawings of the specification Figures 1-4, an insect trapping and photographing device according to an embodiment of the present invention includes a housing cover 1, a lifting seat 2 and a support seat 3 respectively arranged at the top and bottom of the housing cover 1. A vertical rod 9 is fixedly connected between the lifting seat 2 and the housing cover 1. At the inner top end of the housing cover 1, a plurality of connecting bars 11 are fixedly arranged, and a lamp tube 10 is fixedly installed between the plurality of connecting bars 11. Among them, the insect attracting lamp (i.e., the lamp tube 10) can use a more broad-spectrum light than the insect situation forecasting lamps on the market to attract more types of insects, making insect forecasting more accurate. At the bottom of the lifting seat 2, an infrared detector 12 is fixedly installed;

[0055] Inside the housing cover 1, a freezing mechanism 5 for performing low-temperature treatment on the trapped insects is fixedly arranged, and inside the housing cover 1, below the freezing mechanism 5, there is an insect treatment part for treating the insects after low-temperature treatment. The insect treatment part is composed of a feeding mechanism 7 for successively lifting the insects after low-temperature treatment and an image acquisition mechanism 6 for performing multi-directional photographing on the insects that are no longer active after low-temperature treatment.

[0056] It should be noted that in the present invention, the freezing mechanism 5 is used to perform low-temperature treatment on the trapped insects to make the insects no longer active but still alive, so as to ensure that the trapped insects can enter the insect photographing station in a natural posture, and the image acquisition mechanism 6 is used to perform multi-directional photographing on the insects after freezing treatment to better judge the types of trapped insects, thereby laying a foundation for subsequent effective pest control.

[0057] Specifically, as Figures 3-4 and Figure 6 shown, the lifting seat 2 includes an upper arc seat and a lower arc seat which are integrally arranged. At the top of the upper arc seat, a hanging ring 21 is fixedly arranged. At the top of the lower arc seat, a cavity 22 is opened. And at the bottom end of the lower arc seat, a hole plate 23 facing the inner cavity of the housing cover 1 is fixedly installed through a locking screw. At the bottom end of the upper arc seat, a motor 1 is fixedly installed. The output shaft of the motor 1 extends to the end inside the cavity 22 and is fixedly connected with an impeller 25. At the outer top end of the lower arc seat, a plurality of air inlet grooves 26 communicating with the cavity 22 are opened. Among them, the bottom end surface of the upper arc seat can be set as an inward concave structure, and the air inlet grooves 26 are for air inlet in an inclined upward direction, and the air inlet grooves 26 at the lower end are higher than the horizontal plane where the lowest point of the bottom end of the upper arc seat is located, so as to cooperate with the outward convex arc surface structure on the outside of the lifting seat 2 to prevent the falling leaves from blocking the air inlet grooves 26. At the center position on the side of the hole plate 23 facing the impeller 25, a convex part 24 in a hemispherical structure is fixedly arranged, and the spherical surface structure of the convex part 24 can be used to guide the wind blown by the rotation of the impeller 25 to disperse around, so that the insects entering the capture area from all directions can be sent into the freezing station by the downward blowing wind.

[0058] It should be noted that during the use of the trapping and photographing device, it is connected to the hanging ring 21 by means of a rope or a hook, etc., then hung at the use position, and the power supply is turned on. After the lamp tube 10 is lit, the light emitted by the lamp tube 10 is used to attract phototactic insects to approach. Once the approaching insects enter the detection range of the infrared detector 12 (i.e., the area covered by the vertical air outlet of the orifice plate 23), the control terminal will start the motor one to drive the impeller 25 to rotate. The rotating impeller 25 is used to draw the outside air into the cavity 22 from the air inlet groove 26, and then under the guidance of the protrusion 24 of the hemispherical structure, it is dispersed to the periphery and blown vertically downward through the orifice plate 23, so that the insects entering the corresponding area of the orifice plate 23 are directly blown by the wind into the shell cover 1 and wait to enter the freezing area for low-temperature treatment.

[0059] Specifically, as Figures 3-5 , Figure 10 and Figure 13 shown, the freezing mechanism 5 includes a square column 51. Square ring plates 52 are fixedly connected between the outer sides of the top and bottom of the square column 51 and the inner side of the shell cover 1. A through groove 53 is formed in the middle of the square column 51. The through groove 53 is composed of a cylindrical groove arranged in the middle and two through grooves communicating with the cylindrical groove. Among them, the through groove located at the upper end of the cylindrical groove is set as an inverted frustum of a pyramid structure, and the through groove located at the lower end of the cylindrical groove fits the size of the reduced end of the upper through groove. A replacement cylinder 56 is rotatably installed inside the cylindrical groove, and an arc groove 54 is formed inside the inner side of the cylindrical groove. A semiconductor refrigeration sheet 57 is fixedly embedded in the arc groove 54. Among them, the semiconductor refrigeration sheet 57 is formed by connecting an N-type (Bi2Te3—Bi2Se3) semiconductor material and a P-type (Bi2Te3—Sb2Te3) semiconductor material into an electric couple. After the direct current is connected, energy transfer can occur. The joint where the current flows from the N-type element to the P-type element absorbs heat and becomes the cold end, while the joint where the current flows from the P-type element to the N-type element releases heat and becomes the hot end;

[0060] The replacement cylinder 56 is composed of a core shaft and hole discs fixedly arranged at both ends of the outer side of the core shaft. A plurality of partition plates evenly distributed in a ring shape are fixedly arranged between the opposite sides of the two hole discs. Among them, the number of partition plates is set to four (the specific number can be adjusted according to the actual situation), and the area corresponding to the semiconductor refrigeration sheet 57 is covered by the accommodation cavity formed between two adjacent partition plates, ensuring that every time the replacement cylinder 56 rotates 90°, the insects entering the accommodation cavity formed between two adjacent partition plates by the wind can completely enter the freezing station at one time. A U-shaped frame 55 is fixedly arranged at the position corresponding to the core shaft on the outer side of the square column 51, and a motor two for driving the core shaft to rotate is fixedly installed on the outer side of the U-shaped frame 55;

[0061] A guide frame 4 is fixedly provided at the top of the square column 51 for guiding the trapped insects into the through groove 53. The guide frame 4 is also set as an inverted quadrangular pyramid structure. Air inlet holes are provided on the outside of the guide frame 4 and on the top of the square ring plate 52 at the top of the square column 51. Exhaust holes are provided on the outside of the square column 51 and on the outside of the shell cover 1 at the position corresponding to the second motor. The area covered by the exhaust hole on the outside of the square column 51 is as follows: Figure 4 The position shown ensures that when the insects follow the downward airflow into the accommodating cavity formed between two adjacent dividing plates at the upper end, the airflow can be discharged through the exhaust holes of the perforated plate mechanism, thereby trapping the insects inside the accommodating cavity.

[0062] It should be noted that the freezing mechanism 5 mainly uses the semiconductor refrigeration sheet 57 to create a low temperature environment of 0-10°C (temperature is adjustable), so that after the trapped insects enter the freezing area, the insects are no longer active due to the cold in the low temperature environment, thereby maintaining a quiet natural state (lying still), which is conducive to the shooting of photos (that is, the back of the insect can be photographed, which is convenient for subsequent viewing of identification features). After the photos are taken, since the device is mainly used for detection and reporting, it is possible to choose to use a far-infrared heating mechanism or other killing mechanism to kill the collected insects, or to choose not to kill them and directly sweep them out of the device, because not killing the trapped insects can effectively avoid accidentally killing natural enemy insects (beneficial insects). In addition, the use of low temperature treatment to make the insects no longer active but still alive can solve the problem that the insect detection and reporting lamps on the market currently kill insects, resulting in abnormal postures of insects and the inability to capture morphological features for identification.

[0063] Among them, at the beginning, the accommodating cavity formed between two adjacent dividing plates on the exchange cylinder 56 is directly opposite to the bottom end of the traveling groove at the upper end of the cylindrical groove. In the process of the insects attracted by the light entering the freezing station with the downward airflow, the insects will first enter the guide frame 4 with the airflow, and slide to the corresponding accommodating cavity along the inclined surface stored in the guide frame 4, or the insects will directly enter the corresponding accommodating cavity with the airflow. During this period, a part of the airflow will pass through the guide frame 4 and the air inlet holes on the square ring plate 52 located at the top of the square column 51 in turn, and the other part of the airflow will enter the corresponding accommodating cavity and pass through the hole plate and the exhaust holes on the outside of the square column 51 in turn. Both parts of the airflow will enter the accommodating cavity surrounded by the two square ring plates 52 and the outside of the square column 51, and then be discharged through the exhaust holes on the shell cover 1. The design of this airflow discharge structure can not only reduce the damage to the insects entering the corresponding accommodating cavity, but also speed up the airflow discharge speed to prevent the rebounding airflow from driving the insects to fly out of the freezing station again.

[0064] After the air flow is discharged, the insects will be trapped inside the corresponding accommodation cavity. Then, the control terminal controls the second motor to drive the rotation of the switching cylinder 56 by 90°, so that the trapped insects enter the area corresponding to the semiconductor refrigerating sheet 57. The low-temperature environment created by the cold end of the semiconductor refrigerating sheet 57 keeps the insects entering this area inactive but still alive. When the insects intercepted in the next round enter the area corresponding to the semiconductor refrigerating sheet 57 for low-temperature treatment, the insects that have completed the low-temperature treatment in the previous sequence will enter the insect image acquisition station through the through slot at the lower end of the cylindrical groove.

[0065] Specifically, as Figures 3-5 and Figure 7 shown, the image acquisition mechanism 6 includes a bracket 61 fixed to the inner side of the housing cover 1 and a swing plate 62 hinged to the bottom of the corresponding square ring plate 52. A swing assembly for intermittently driving the swing plate 62 to swing is provided between the swing plate 62 and the corresponding square ring plate 52. The feeding mechanism 7 is installed on one side of the housing cover 1 away from the bracket 61. A photographing assembly 63 is provided on the side of the bracket 61 facing the feeding mechanism 7.

[0066] A broken line plate 64 is fixedly connected to the top of the bracket 61. A vertical plate 65 is fixedly provided at the high-position end of the top of the broken line plate 64. A plurality of partition plates 66 are fixedly provided on the side of the vertical plate 65 facing the swing plate 62. The feeding area at the high-position end of the top of the broken line plate 64 can be divided into multiple small areas by the plurality of partition plates 66, so that the insects sliding down along the swing plate 62 can enter different small areas, avoiding local accumulation and affecting subsequent photographing. A baffle 68 is fixedly connected between one ends of the plurality of partition plates 66 and is in contact with the corresponding end of the swing plate 62. The baffle 68 can be used to block the insects sliding down along the swing plate 62 in advance, enabling the sliding insects to be evenly distributed at the bottom end of the swing plate 62 that swings downward. Then, during the reset process of the swing plate 62, the insects are lifted and sent into the small areas at the corresponding positions. A first cylinder 67 is fixedly installed at the position between two adjacent partition plates 66 on the other side of the vertical plate 65. The end of the telescopic end of the first cylinder 67 is fixedly connected to a push plate. In addition, limit strips can be provided on both sides of the top of the swing plate 62 to prevent the falling insects from directly sliding off the swing plate 62 and unable to enter the feeding area at the high-position end of the top of the broken line plate 64.

[0067] A leakage hole 611 is opened at the low-position end of the top of the broken line plate 64, and a second side baffle 610 for partially enclosing the leakage hole 611 is fixedly provided at the low-position end of the top of the broken line plate 64. First side baffles 69 are fixedly provided on both sides of the inclined section at the top of the broken line plate 64.

[0068] It should be noted that in the initial state, the lower end of the top surface of the swing plate 62 is horizontally coplanar with the upper end surface of the baffle 68. When the insects treated with low temperature fall with the rotation of the exchange cylinder 56, the rotating exchange cylinder 56 will drive the swing assembly to make the swing plate 62 deflect downward, so that the lower end of the swing plate 62 in the initial state sinks downward, so that a pre-support area is formed between the swing plate 62 that deflects downward and the baffle 68, so that after the insects fall on the swing plate 62, they directly slide down into the pre-support area, and the insects are blocked by the baffle 68 and are flat on the bottom of the swing plate 62, and then as the exchange cylinder 56 continues to Rotate, the swing assembly releases the effect on the swing plate 62, allowing the swing plate 62 that automatically resets to lift the insects on the flat cloth upward, so that the insects on the flat cloth fall into the corresponding cell, and then the cylinder 1 67 of the cell is used to push the push plate to push the insects inside the corresponding cell, so that the insects slide down to the position of the leak hole 611 under the restriction of the side block 1 69 and the side block 2 610, and fall onto the material receiving mechanism 7 through the leak hole, and then use the shooting assembly 63 to perform multi-directional detection on the insects on the material receiving mechanism 7, so as to better determine the insect types in the planting area, and provide a theoretical basis for subsequent pest control;

[0069] In the above-mentioned process of insects falling, the present invention is explained on the basis that the number of insects entering each cell is single. In the actual trapping and shooting process, if the insects are small, there may be multiple insects, but the fallen insects will not form a pile, thus ensuring the accuracy of the shooting results.

[0070] Specifically, Figure 8 As shown, the swing assembly includes a guide groove 1 612 opened on both sides of the middle of the top of the swing plate 62 and a guide groove 2 613 opened on the square ring plate 52 at the bottom end of the square column 51 and corresponding to the guide groove 1 612. A guide groove 3 614 connected to both guide grooves 1 612 is opened on one side of the swing plate 62. A round rod 615 is inserted inside the guide groove 3 614. Round plates 616 are fixedly sleeved at the positions corresponding to the insides of the two guide grooves 1 612 on the outside of the round rod 615. The two round plates 616 are fixedly provided with movable through holes on the outside. Corresponding to the pointer bar 617 of the second guide groove 613, the swing assembly also includes a plurality of (the number here is set to correspond to the number of dividing plates on the exchange cylinder 56) cams 618 fixed on the outer side of the end of the core shaft away from the U-shaped frame 55, and an arc spring 619 fixedly connected between the swing plate 62 and the square ring plate 52, wherein, when the arc spring 619 is in a natural state, the low end of the top end surface of the swing plate 62 is horizontally coplanar with the upper end surface of the baffle 68, and the swing plate 62 in this state is intended to be the initial state.

[0071] It should be noted that during the process of using the swinging component to drive the swing plate 62 to swing downward, as the insects after cryogenic treatment gradually move out of the freezing area under the rotation of the replacement cylinder 56, the rotating replacement cylinder 56 will drive the cam 618 to rotate synchronously. Before the insects move out of the freezing area and fall onto the swing plate 62, the cam 618 rotating with the replacement cylinder 56 will press the pointer bar 617 downward. During this process, the pointer bar 617 moves vertically downward under the restriction of the corresponding guide groove two 613, and the circular plate 616 and the circular rod 615 that move synchronously with the pointer bar 617 are used to push the swing plate 62 to swing downward. At the same time, the stretching arc spring 619 is stretched to form a pre-support area between the downward-swinging swing plate 62 and the baffle 68. The setting of the guide groove three 614 can enable the circular plate 616 and the circular rod 615 to move along the guide groove three 614 during the swinging process of the swing plate 62, ensuring that the downward linear movement of the pointer bar 617 is unobstructed;

[0072] After a pre-support area is formed between the downward-swinging swing plate 62 and the baffle 68, as the replacement cylinder 56 continues to rotate, the insects that have moved out of the freezing area will fall onto the top of the swing plate 62. During the process of staying inside the pre-support area, the slipping insects are evenly distributed at the bottom end of the downward-swinging swing plate 62. When the cam 618 releases the extrusion of the pointer bar 617 as it rotates with the replacement cylinder 56, the swing plate 62 will reset under the restoring force of the arc spring 619, thereby lifting the insects evenly distributed inside the pre-support area upward, and then allowing the insects to automatically roll into the corresponding small area to wait for pushing.

[0073] Specifically, as Figures 3-4 and Figure 11 shown, the material receiving mechanism 7 includes a cross plate 72 fixed inside the housing 1 and a T-shaped groove 71 opened inside the housing 1. A T-shaped seat 73 is slidably installed inside the T-shaped groove 71. A cylinder two 74 is fixedly installed on the top of the cross plate 72, and the end of the telescopic end of the cylinder two 74 is fixedly connected to the T-shaped seat 73;

[0074] One end of the T-shaped seat 73 is fixedly installed with a motor five, and the end of the output shaft of the motor five is fixedly installed with a material receiving plate 76. Retaining rings 75 are fixedly provided at the positions corresponding to the leakage holes 611 at the top and bottom of the material receiving plate 76. Among them, both the material receiving plate 76 and the retaining rings 75 are made of transparent acrylic plates, which can prevent occlusion during the process of photographing insects and improve the photographing effect.

[0075] It should be noted that in the process of using cylinder 1 67 to push the push plate to push out the insects inside the corresponding cell, the control end will control cylinder 2 74 to pull the T-shaped seat 73 up, thereby driving the receiving plate 76 to approach the leak hole 611 on the folding plate 64, and automatically reset after catching the insect, and then use the shooting component 63 to shoot the insects in a natural state on the receiving plate 76. When a round of shooting is completed, the motor five will drive the receiving plate 76 to flip 180°, so that the insects that have completed the shooting can be separated from the receiving plate 76 and wait for the next round of receiving.

[0076] Specifically, Figures 7-9 As shown, the shooting component 63 includes a motor three fixedly mounted on the bracket 61, the output shaft end of the motor three is fixedly connected to a limiting frame 632, a partition bar 633 is fixedly provided on the inner side of the limiting frame 632, an arc-shaped tooth plate 635 and a gear 634 are meshed inside the limiting frame 632, and a motor four for driving the gear 634 to rotate is fixedly provided on the outer side of the limiting frame 632, a through slot 636 is penetrated on one side of the arc-shaped tooth plate 635, and the partition bar 633 is movably penetrated inside the through slot 636, and the partition bar 633 can be used to assist in limiting the arc-shaped tooth plate 635, and cameras 631 for taking pictures of trapped insects are installed at both ends of the inner side of the arc-shaped tooth plate 635.

[0077] It should be noted that in the process of using the shooting component 63 to shoot the insects on the feeding plate 76, the control end will be used to control the motor four drive gear 634 to rotate, and the rotating gear 634 will be used to drive the arc-shaped tooth plate 635 to rotate, so that the cameras 631 at the inner ends of the arc-shaped tooth plate 635 can be used to perform multi-point shooting of the upper and lower sides of the insects in their natural state. At the same time, the control end will also be used to control the motor three to drive the limiting frame 632 to rotate, so as to shoot the side of the insects in their natural state. In this way, multi-directional shooting of insects can be achieved, and then the collected insect images can be comprehensively analyzed by a computer to determine the type of insects and count them.

[0078] Example 2: Refer to the attached instructions Figure 2 and Figure 12 In one embodiment of the present invention, an insect trapping and photographing device is provided, wherein a buckle mechanism 8 is provided between the shell cover 1 and the bracket 3 for detachably mounting the bracket 3 on the bottom end of the shell cover 1, wherein the buckle mechanism 8 comprises a trapezoidal block 81 fixed to the bottom end of the outer side of the shell cover 1 and two side frames 82 fixed to the top end of the outer side of the bracket 3 and corresponding to the trapezoidal block 81, wherein a buckle plate 83 is rotatably mounted between the two side frames 82 via a rotating rod, wherein a straight spring 84 is fixedly connected between the inner side of one end of the buckle plate 83 away from the corresponding trapezoidal block 81 and the bracket 3, wherein when the straight spring 84 is in a natural state, the buckle plate 83 is just as Figure 12 In the state shown, the shell cover 1 and the bracket 3 are fastened and fixed;

[0079] The snap-fitting mechanism 8 also includes a truncated cone fixed on the bottom end surface of the shell cover 1 and a recessed groove opened on the top end surface of the bracket 3 and corresponding to the truncated cone. The truncated cone is movably inserted into the corresponding recessed groove. There are four truncated cones and recessed grooves, each of which is arranged in a cross shape. The inserted truncated cones and recessed grooves can be used to prevent the bracket 3 and the shell cover 1 from relative displacement after snapping together.

[0080] It should be noted that in the process of buckling the bracket 3 to the bottom of the shell cover 1, the groove on the bracket 3 is aligned with the cone on the shell cover 1, and then the bracket 3 is directly moved upward, and the trapezoidal block 81 is used to squeeze the upper end of the buckle plate 83 at the corresponding position, so that the upper end of the buckle plate 83 is deflected outward and the spring at the lower end is pressed down. After the buckle plate 83 is offset from the corresponding trapezoidal block 81, the buckle plate 83 will be reset under the action of the corresponding straight spring 84 to complete the buckling action. Conversely, the buckling state can be quickly released by pressing down the lower end of the buckle plate 83, and disassembly and assembly are convenient and quick.

[0081] In the above technical scheme, the infrared detector 12 mentioned is a pet-proof passive infrared detector for space protection with the model number PA-6412PI; the motor mentioned is a servo motor with the model number JSMA-PUC02D; the cylinder mentioned is a single-acting cylinder with the model number DSA25N200; the camera 631 mentioned uses a high-frequency infrared flash lamp with a flash frequency of up to 2000 times per second, which can provide high-frequency flashing when used at night, and play the role of fill light for taking pictures.

[0085] S3. Insect cleaning: a. Use the second motor to drive the replacement cylinder 56 to continue rotating, so that the insects after low-temperature treatment fall onto the top of the swing plate 62 and slide down along the swing plate 62 to different regions at the high-position end of the top of the folded line plate 64. Then, the first cylinder 67 corresponding to it pushes the inactive insects after low-temperature treatment out of the area where they are located, and they fall onto the top of the receiving plate 76 through the leakage holes 611;

[0086] b. Use the fourth motor to drive the gear 634 to rotate, and use the rotating gear 634 to drive the arc-shaped toothed plate 635 to rotate. At the same time, cooperate with the third motor to drive the limiting frame 632 to rotate, and use the two cameras 631 inside the arc-shaped toothed plate 635 to take multi-angle photos of the insects on the receiving plate 76;
