Description

Technical Field

[0001] The present invention relates to the technical field of separation and counting, and particularly relates to an intelligent separation and counting device for coleopteran saprophagous insects. Background Art

[0002] Coleopteran saprophagous insects are one of the common pests and diseases in farmland. When there are excessive coleopteran saprophagous insects in the soil of farmland, although coleopteran saprophagous insects mainly feed on decaying organic matter, during the foraging process of coleopteran saprophagous insects, they will also gnaw on the roots, stems and branches of crops, causing irreparable damage to the growth of crops. In addition, during the movement of coleopteran saprophagous insects, they will also transmit diseases, causing disease problems in crop production. Therefore, it is necessary to strictly ensure the proportion of coleopteran saprophagous insects in the soil to ensure the normal growth of crops.

[0003] In the existing agricultural production process, in order to judge the pest and disease situation in a certain farmland, agricultural inspectors need to take samples of the soil in the farmland and then perform screening operations on the soil samples. Because before coleopteran saprophagous insects move freely, they usually survive in the soil in the form of larvae. By screening out the coleopteran saprophagous larvae in the soil and calculating the number of coleopteran saprophagous larvae in the soil, it is possible to judge whether the proportion of coleopteran saprophagous insects in the farmland is normal.

[0004] When the existing technology screens the soil and insect larvae, most of them screen the soil, impurities and insect larvae according to the volume difference between the soil and the insect larvae. And many insect larvae have completed molting operations in the soil and are discharged from the soil. Therefore, there are generally two species, larval molts and insect larvae, with relatively close volumes in the soil samples collected by the existing technology. It is difficult for the separation and counting devices in the existing technology to separate the larval molts and insect larvae at one time, resulting in inaccurate judgment of the specific number of insect larvae in the soil sample by the subsequent counting device. Summary of the Invention

The receiving trough is moved into the bottom of the larvae discharge bucket, and the insect larvae and insect sloughs are discharged into the receiving trough. During the falling process of the larvae, air is blown toward the upper side of the outer arc surface of the arc-shaped piece through the nozzle. Due to the difference in mass between the larvae and the exuviae, the air flow can make the falling paths of the larvae and the exuviae different, so that the larvae and the exuviae are transported toward the larvae discharge slot and the exuviae discharge slot respectively, which is convenient for collecting the exuviae. After the larvae enter the sloped trough body, the receiving trough body is moved to the top of the conveyor belt conveyor, and the separated larvae are put into the conveyor belt conveyor in multiple times. During the conveyor belt conveyoring the larvae, the number of larvae is counted by the infrared counting device to judge the proportion of insects in the soil sample. Compared with the insect-soil separation equipment in the prior art, the present invention can effectively separate larvae and exuviae of similar size, which is convenient for the counting equipment to judge the actual number of larvae.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1 to 11, an intelligent separation and counting device for coleopteran saprophagous insects, including a conveyor belt conveyor 1. On one side of the conveyor belt conveyor 1, there is an infrared counting device 2. The conveyor belt conveyor 1 is a technical device in the prior art that drives an object to move horizontally, which is a well-known prior art device in the field. By dispersing and transporting the larvae separated from the soil in parallel on the conveyor belt conveyor 1, after the larvae pass through the bottom of the infrared counting device 2, the infrared counting device 2 takes pictures and counts the larvae. The infrared counting device 2 used in the present invention is also a well-known prior art device in the field. The specific working principle can refer to the cooperation method of the Raspberry Pi 4B single-board computer and the Raspberry Pi V2 high-definition camera to achieve the function of counting the larvae.

[0035] It further includes an installation frame 3 arranged on the other side of the conveyor belt conveyor 1. Inside the installation frame 3, there is a double-screening mechanism with impurity screening function and larva screening function. The double-screening mechanism first separates the impurities in the sample, and then separates the soil and larvae. The double-screening mechanism includes a receiving frame 8 and an installation groove frame 9. The receiving frame 8 is fixedly connected inside the installation frame 3. The installation groove frame 9 is located above the receiving frame 8. Between the installation groove frame 9 and the inner bottom wall of the receiving frame 8, there is a vibration spring seat 10. The installation groove frame 9 is fixedly connected with an upper separation plate 11 and a lower separation plate 12 in sequence from top to bottom. In the middle of the upper separation plate 11 and the lower separation plate 12, there is a discharge hopper body 13 for discharging the soil and impurities. The installation frame 3, the receiving frame 8, the installation groove frame 9, the upper separation plate 11, and the lower separation plate 12 are all inclined towards the conveyor belt conveyor 1. When separating a soil sample containing gravel impurities, insect larvae, insect molts, and soil, first add the soil sample to the upper separation plate 11. When the soil sample is discharged from the upper separation plate 11, separate the gravel, grass and wood chips and other impurities in the soil sample. Then continue to discharge the soil sample onto the lower separation plate 12 to continue separating the insect molts and larvae in the soil, so that the insect molts and larvae stay on the lower separation plate 12.

[0036] When the installation groove frame 9 is separating the soil, the installation groove frame 9 will vibrate between multiple vibration spring seats 10 in the receiving frame 8, which is convenient for the soil to be separated in the installation groove frame 9 and move along the upper separation plate 11 and the lower separation plate 12.

[0037] Installation grooves are provided on both sides of the upper separation plate 11. An impurity screening plate 14 is arranged in the installation groove. The soil sample that has not undergone separation operation is poured onto the surface of the upper separation plate 11. Since the upper separation plate 11 is inclined, during the movement of the soil sample on the impurity screening plate 14, the soil components, larvae, and insect molts in the soil sample will enter the lower separation plate 12, while impurities such as gravel and grass clippings in the soil sample will remain on the surface of the impurity screening plate 14. With the vibration of the installation groove frame 9, the gravel and grass clippings are moved into the discharge hopper body 13, and through the discharge hopper body 13 on the upper separation plate 11 and the lower separation plate 12, the gravel and grass clippings are conveyed to the bottom of the installation frame 3;

[0038] Installation grooves are also provided on both sides of the lower separation plate 12. A larva screening plate 15 and a larva discharge hopper 16 are arranged in the installation groove. After the soil sample undergoes the separation operation by the impurity screening plate 14, the soil sample will enter the surface of the larva screening plate 15. After the soil sample undergoes the separation operation by the larva screening plate 15, the larvae and insect molts in the soil sample will remain on the surface of the larva screening plate 15. The finally separated soil sample will be discharged to the bottom of the installation frame 3. During the vibration of the installation groove frame 9, the larvae and insect molts are discharged through the larva discharge hopper 16;

[0039] It should be added that the bottom of the installation frame 3 is set as an inclined surface. The separated soil sample and gravel impurities will fall onto the inner bottom wall of the installation frame 3. A discharge port 34 is provided at the bottom of the installation frame 3. The installation frame 3 is supported and fixed by two support frames 35. A support rod 36 for placing the collection tank body is arranged in the middle of the support frame 35 to realize the collection and discharge of the separated soil sample.

[0040] The top of the installation frame 3 is fixedly connected with parallel slide rails 17. A sample filling tank body 18 is slidably connected between the two parallel slide rails 17. Vibrators 19 are arranged on both sides of the sample filling tank body 18. The output ends of the vibrators 19 are in contact with the installation groove frame 9. When it is necessary to fill the unseparated soil sample onto the impurity screening plate 14, by adjusting the position of the sample filling tank body 18, the bottom of the sample filling tank body 18 is aligned with the top side of the impurity screening plate 14. Then, the soil sample to be separated is filled into the sample filling tank body 18, and the sample filling tank body 18 is driven to move horizontally between the two parallel slide rails 17, so that the sample filling tank body 18 moves from one side of the impurity screening plate 14 to the other side. The length of each impurity screening plate 14 can complete the separation treatment operation of a soil sample. When the sample filling tank body 18 discharges the soil sample, the vibrator 19 is in contact with the top of the installation groove frame 9, and the vibrator 19 is used to drive the installation groove frame 9 to vibrate quickly in a small range, so that the soil sample can be smoothly separated between the impurity screening plate 14 and the larva screening plate 15. In the present invention, two impurity screening plates 14 and larva screening plates 15 are respectively prepared. When the impurity screening plate 14 and the larva screening plate 15 on one side are not cleaned, in order to avoid the mixing of soil samples, the impurity screening plate 14 and the larva screening plate 15 on the other side can be used for the separation operation.

[0041] The material receiving trough body 4 is horizontally movably arranged in the installation frame 3, and the material receiving trough body 4 is located at the bottom of the double screening mechanism. A partition plate 5 is fixedly connected to the bottom of the material receiving trough body 4. Larva discharge openings and molt discharge openings are respectively communicated with both sides of the bottom of the partition plate 5. An arc-shaped piece 6 is fixedly connected to the middle of the top end of the partition plate 5. A plurality of air jet heads 7 are arranged on one side of the top of the material receiving trough body 4. An arc-shaped deflector 41 is arranged in the air outlet end of the air jet head 7. A diversion groove 42 is formed in the middle of one end of the arc-shaped piece 6 close to the air jet head 7. The diversion groove 42 corresponds to the air jet head 7 one by one. The arc-shaped deflector 41 divides the air flow discharged from the air jet head 7 into two directions. The blowing direction of one air flow is towards the upper side of the outer arc surface of the arc-shaped piece 6, so as to convey the larvae and molts into the larva discharge opening and the molt discharge opening respectively. The blowing direction of the other air flow is towards the diversion groove 42. After the air flow passes through the diversion groove 42, it is shunted to blow and disperse the larvae in the falling process. After the larva screening plate 15 screens out the larvae and molts, with the vibration of the installation trough frame 9, the larvae and molts move together towards the larva discharge hopper 16 and are discharged through the larva discharge hopper 16. In the process of the larvae and molts descending, gas is sprayed towards the upper side of the outer arc surface of the arc-shaped piece 6 through the air jet head 7. Due to the mass difference between the larvae and the molts, when encountering the air flow, both the larvae and the molts will tilt and fall in the same direction. However, due to the mass difference between the larvae and the molts, the tilting falling arc of the larvae is smaller, so that the larvae contact the outer arc surface of the arc-shaped piece 6, realizing the movement of the larvae and the molts into the larva discharge opening and the molt discharge opening respectively. The selected air jet head 7 with a large air flow coverage range but a small air flow driving force is used;

[0042] The bottom of the arc-shaped deflector 41 is arc-shaped. After the air flow discharged from the air jet head 7 is shunted by the arc-shaped deflector 41, the air flow located at the lower side, after being guided by the arc-shaped deflector 41, will blow into the diversion groove 42. The bottom of the arc-shaped deflector 41 is provided with a trough body with a flow collecting effect, so that after the air flow passes through the arc-shaped deflector 41, the air flow will not diffuse and directly blow into the diversion groove 42. The air flow directly starts to diffuse along the side wall of the diversion groove 42 in the diversion groove 42. For the larvae screened out by the arc-shaped piece 6, in the falling process, after the larvae are in direct contact with the air flow, the larvae continue to fall into the grid plate 28 after contacting the side wall of the diversion groove 42. After the larvae are in contact with the air flow diffused by the diversion groove 42, the larvae will change their original moving path under the thrust of the air flow in the opposite direction, so that the larvae are dispersed to other areas of the grid plate 28, which is convenient for the larvae to fall onto the conveyor belt 1 in batches subsequently.

[0043] A sliding chute body 20 is fixedly connected to the side wall of the installation frame 3. A sliding seat 21 is horizontally slidably connected in the sliding chute body 20. Connecting brackets 22 are fixedly connected to both the upper and lower sides of the sliding seat 21. The material receiving chute body 4 and the sample filling chute body 18 are respectively fixedly connected to the corresponding connecting brackets 22. A lead screw transmission assembly is arranged in the sliding chute body 20. The sliding seat 21 is threadedly connected to the lead screw transmission assembly. The lead screw transmission assembly includes a transmission lead screw 37. The transmission lead screw 37 is rotatably connected in the sliding chute body 20. The transmission lead screw 37 is threadedly connected to the sliding seat 21. A first drive motor 38 is arranged on the sliding chute body 20. The output end of the first drive motor 38 is fixedly connected to the transmission lead screw 37. When the first drive motor 38 is started to drive the transmission lead screw 37 to rotate, the sliding seat 21 moves horizontally in the sliding chute body 20. The sliding seat 21 and the connecting brackets 22 drive the sample filling chute body 18 and the material receiving chute body 4 to move horizontally together. After the sample filling chute body 18 discharges the soil sample completely, the sliding seat 21 is continuously moved to move the material receiving chute body 4 to the lower side of the larva discharge hopper 16.

[0044] An air storage cylinder body 23 is arranged at the inner top of the material receiving chute body 4. A plurality of air jet heads 7 are all communicated with the air storage cylinder body 23. A fan 24 is arranged on one side of the installation frame 3. An air delivery pipe 25 is communicated between the output end of the fan 24 and the air storage cylinder body 23. In order to supply air to the plurality of air jet heads 7, after the fan 24 is started to suck the gas in the external environment, it is then conveyed into the air storage cylinder body 23 through the air delivery pipe 25, and finally the air storage cylinder body 23 supplies air between the plurality of air jet heads 7.

[0045] A collection and discharge structure is connected to the bottom of the larva discharge notch, which can discharge larvae onto the conveyor belt conveyor 1 in batches. The collection and discharge structure includes a sloped trough body 26 and a rotating shaft 27. The sloped trough body 26 is connected to the bottom of the larva discharge notch. A discharge notch is formed at the bottom of the sloped trough body 26. A through groove is formed on the inclined surface of the sloped trough body 26. A checkered plate 28 is elastically arranged in the through groove. Rotating shafts 27 are rotatably arranged inside and outside the sloped trough body 26. A gear coupling 29 is arranged between the two rotating shafts 27. Among them, a plurality of material pusher pieces 30 are fixedly connected to the circumference of the rotating shaft 27 located inside the sloped trough body 26, and an eccentric knocking member 31 is arranged on the other rotating shaft 27. The eccentric knocking member 31 contacts the checkered plate 28. After the larvae pass through the larva discharge notch, they enter the sloped trough body 26. The larvae are scattered and fall onto the top of the checkered plate 28. A second driving motor 39 is arranged on the sloped trough body 26. The output end of the second driving motor 39 is in transmission cooperation with the gear coupling 29. By horizontally moving the docking trough body 4, the discharge notch is moved directly above the larva discharge channel 33. The second driving motor 39 is started, and the two rotating shafts 27 are driven to rotate through the gear coupling 29. First, the rotating shaft 27 arranged outside the sloped trough body 26 drives the eccentric knocking member 31 to knock on the checkered plate 28. During the vibration of the checkered plate 28, the larvae gradually move towards the discharge notch. The larvae will fall onto the surface of the material pusher pieces 30, and the rotating shaft 27 drives the plurality of material pusher pieces 30 to rotate around the center point of the rotating shaft 27, so that the larvae are discharged from the sloped trough body 26.

[0046] A collection trough body 32 is installed in the insect molt discharge notch, and the insect molts separated by the airflow will enter the collection trough body 32. After a certain amount of insect molts have accumulated, the user disassembles and cleans the collection trough body 32.

[0047] A larva discharge channel 33 is fixedly connected to one side of the conveyor belt conveyor 1 close to the installation frame 3. In order to avoid the problem of the larvae floating away during the falling process caused by the airflow in the external environment, after the larvae are directly discharged through the sloped trough body 26, the larvae will enter the larva discharge channel 33 and finally fall onto the conveyor belt conveyor 1.

[0048] A larva collection box 40 is arranged on one side of the conveyor belt conveyor 1 away from the larva discharge through groove. After the conveyor belt conveyor 1 drives the larvae through the infrared counting device 2, the larvae will be conveyed into the larva collection box 40 for centralized processing of the counted larvae.

[0049] The working principle or usage process of this intelligent separation and counting device for coleopteran saprophagous insects is as follows:

[0050] First, align the bottom of the sample filling tank 18 with the top side of the impurity screening plate 14. Then, pour the soil sample to be separated into the sample filling tank 18, and drive the sample filling tank 18 to move horizontally between the two parallel slide rails 17, so that the sample filling tank 18 moves from one side of the impurity screening plate 14 to the other side. When the sample filling tank 18 discharges the soil sample, the vibrator 19 contacts the top of the mounting groove frame 9, and the vibrator 19 is used to drive the mounting groove frame 9 to vibrate quickly in a small range, so that the soil sample smoothly falls onto the larva screening plate 15 after being separated by the impurity screening plate 14, and then the larva screening plate 15 is used to perform secondary separation on the soil sample, so that the larvae and the insect molts are retained on the surface of the larva screening plate 15;

[0051] After the larva screening plate 15 is used to screen out the larvae and the insect molts, with the vibration of the mounting groove frame 9, the larvae and the insect molts move together in the direction of the larva discharge hopper 16, and are discharged into the receiving tank 4 through the larva discharge hopper 16. During the downward movement of the larvae and the insect molts, gas is sprayed onto the upper side of the outer arc surface of the arc-shaped piece 6 through the air jet head 7. Due to the mass difference between the larvae and the insect molts, when encountering the air flow, both the larvae and the insect molts will tilt and fall in the same direction. However, due to the mass difference between the larvae and the insect molts, the larvae will have a smaller tilt fall arc, so that the larvae contact the outer arc surface of the arc-shaped piece 6, realizing the movement of the larvae and the insect molts into the larva discharge slot and the insect molt discharge slot respectively;

[0052] After passing through the larva discharge slot, the larvae enter the slope-shaped tank 26, and the larvae are scattered and fall onto the top of the grid plate 28. Start the second drive motor 39, and drive the two rotating shafts 27 to rotate through the gear coupling 29. First, the rotating shaft 27 arranged outside the slope-shaped tank 26 drives the eccentric knocking piece 31 to knock on the grid plate 28. During the vibration of the grid plate 28, the larvae gradually move in the direction of the discharge slot, and the larvae will fall onto the surface of the material pushing piece 30, so that the rotating shaft 27 drives the multiple material pushing pieces 30 to rotate around the center point of the rotating shaft 27, and the larvae are discharged from the slope-shaped tank 26;

[0053] After passing through the larva discharge channel 33, the larvae fall onto the conveyor belt 1, and the larvae separated from the soil are conveyed in parallel and dispersed on the conveyor belt 1, so that after passing through the bottom of the infrared counting device 2, the infrared counting device 2 takes pictures and counts the larvae, and then conveys the larvae into the larva collection box 40 for centralized processing of the counted larvae.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
