Description

Technical Field

[0001] This disclosure relates to the technical field of aflatoxin detection equipment, and in particular to a rapid detection device for aflatoxin in peanuts. Background Technology

[0002] In the process of processing peanuts, it is often necessary to test for aflatoxin in peanuts in order to ensure food safety. To improve the detection efficiency of aflatoxin in peanuts, optical sensing sorting technology is often used for online rapid detection of aflatoxin in peanuts. Patent application CN201811128179.3 discloses an aflatoxin residue detection device for a grain dryer. The device involves feeding grain to be tested onto a detection plate via a feeding pipe. The detection plate has detection holes, allowing the grain to fall evenly and directly into these holes. Excess grain is pushed out by a pusher plate and falls into a reuse bin. The grain is then tested again. If the grain in the detection hole contains aflatoxin, it will be excited by an ultraviolet lamp and emit blue or green fluorescence. This is detected by a color sensor, which transmits a data signal to a microcontroller. The microcontroller then controls a rotating motor to rotate the carrying column, causing the grain containing aflatoxin to fall directly into a recycling bin. Conversely, grain without aflatoxin will not be excited by the ultraviolet lamp and will remain in the detection hole. Subsequently, the grain is rotated by a rotating motor... The device moves the grains along with the overturned detection plate, causing them to fall into the storage box, thus enabling the detection of aflatoxin residues. Patent application CN201810724690.3 discloses an aflatoxin detection device and method. This device uses an absorption band made of montmorillonite to absorb aflatoxin in the sample solution and detects fluorescence under ultraviolet light to determine if the sample solution contains aflatoxin. This replaces the existing antibody-based aflatoxin capture method, is simple to operate, and is unaffected by the environment. By using the different angles between the emitted light and the absorption bands to create different fluorescence intensities, the device creates a curve of the fluorescence intensity of each absorption band and matches it with curves of various concentrations of standard aflatoxin in a database. The device finds the aflatoxin concentration corresponding to the curve that matches the original curve, thereby detecting the aflatoxin concentration in the sample solution. According to its publicly available technical solutions, existing aflatoxin detection equipment has several drawbacks. First, it cannot effectively and evenly distribute peanuts, leading to missed detections due to peanuts covering each other, which compromises the accuracy of the results. Second, during the detection and transport of peanuts, it cannot effectively remove fallen peanut skins and other impurities, which can further affect the accuracy of the results. Third, when filtering and cleaning peanut skins and other impurities, it cannot effectively switch between passive and driven cleaning based on the cleaning resistance. Summary of the Invention

[0012] Optionally, a support sleeve is bolted to the other end of the filter cartridge, the motor is bolted to the outer side of the support sleeve, a main shaft is mounted on the output shaft of the motor, one end of the main shaft passes through the support sleeve and extends to the inner side of the filter cartridge, a fan blade is bolted to one end of the main shaft, the outer side of the screw plate is clamped on the inner wall of the filter cartridge, and the screw plate is mounted on the outer side of the main shaft by a support rod.

[0013] Optionally, a protrusion is welded to the other end of the spindle. The protrusion is located inside the support sleeve. Buttons are bolted to the top and bottom of the support sleeve.

[0014] Optionally, a housing is bolted to the bottom of the other end of the filter cartridge, and an opening is provided at the bottom of the other end of the filter cartridge. The filter cartridge is connected to the housing through the opening, and a side door is installed on the housing.

[0015] The technical solution provided in this disclosure may include the following beneficial effects: Pour the peanuts into the inside of the hopper, then turn on motor one and the feeding valve. Motor one drives the belt via the rotating roller, which in turn drives the rotating rod and the chuck to rotate clockwise. The bottom of the chuck rotates clockwise due to friction with the sliding plate. The friction between the chuck and the rotating rod causes the rotating rod to rotate counterclockwise. The peanuts fall onto the sliding plate through the feeding valve and are then pushed to the right by the rotating rod. Simultaneously, the counterclockwise rotation of the rotating rod causes the peanuts to rotate clockwise on the sliding plate, preventing them from slipping between the rotating rod and the sliding plate. The shovel removes any excess peanuts. The system ensures that the peanuts move in a single layer on top of the slide plate. The shovel plate can move inside the inclined sleeve via a spring, preventing damage to the peanuts and ensuring their integrity and quality. Each peanut can roll from the bottom of the machine under the push of the rotating rod, allowing for effective and comprehensive inspection of each peanut by the detector. This avoids any omissions due to obstructions from the peanuts themselves or other materials, ensuring the effectiveness of the peanut inspection.

[0016] The fan in the lower ventilation duct blows air into the inside of the blower hood, and then blows it upwards through the air holes, causing the peanut skins and other impurities that have fallen off the peanuts to be blown upwards. The fan in the upper ventilation duct generates suction on the suction hood, sucking the peanut skins and other impurities into the inside of the upper ventilation duct, where they are then filtered out by the filter cartridge. A partition screen is used to prevent peanuts from being blown into the inside of the upper ventilation duct due to sudden increases in local airflow. When a large peanut skin gets stuck at the bottom of the partition screen, the second motor pushes the support block through the lead screw. The support block drives the roller to move back and forth at the bottom of the partition screen, and the protrusions break or push the peanut skins adsorbed at the bottom of the partition screen into the inside of the upper ventilation duct. Then, the airflow carries them to the inside of the filter cartridge for filtration. This effectively cleans the peanut skins and other impurities, while preventing the peanuts from being accidentally cleaned. It also prevents peanut skins with a diameter larger than the peanuts from clogging the partition screen, ensuring ventilation efficiency and thus ensuring the cleaning effect of peanut skins and other impurities. This prevents peanut skins and other impurities from interfering with the detection of peanuts and improves the quality of the peanuts.

[0017] Airflow disperses the rotating fan blades, which, via the main shaft, drive the screw plate to scrape and clean the peanut skins and other impurities filtered into the filter cartridge. This continues until the screw plate scrapes the peanut skins and other impurities through the opening to the inside of the housing, effectively cleaning the filter cartridge and preventing clogging. As the main shaft rotates, it continuously pushes the rollers through the protrusions. The rollers then press the button, causing air inside the button to be expelled through a one-way valve. After the protrusions lose their pressure on the rollers, the negative pressure created inside the button forces air to slowly enter through the gaps in the button, causing it to slowly reset. Before the button fully resets, it is again pressed by the protrusions and rollers. When the screw plate, main shaft, and other mechanisms experience excessive resistance from peanut skins and other impurities, or high mechanical friction, resulting in slow rotation or even complete stoppage, the protrusions cannot promptly press and push the rollers, thus resetting the button, energizing the motor, and driving the main shaft to rotate. The main shaft then drives the fan blades and screw plate to rotate, which improves suction power, ensuring effective absorption of peanut skins and other impurities, and also increases the cleaning speed of the screw plate, ensuring efficient cleaning of the filter cartridge. The system can automatically perform non-powered cleaning or switch to electric cleaning based on the resistance of the fan blades, screw plate, and main shaft, ensuring effective cleaning of the filter cartridge while saving energy.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a rapid detection device for aflatoxin in peanuts is characterized by comprising: a main unit, a feeding assembly, and a purification assembly. The main unit includes a body 1 and a casing 2. A detection assembly is mounted on the casing 2, comprising a detector 3 and a display 4. A feeding assembly is mounted on the body 1, comprising a material hopper 5 and a feeding valve 6. The feeding assembly includes a sliding plate 10 and a belt 9. A rotating rod 11 and a roller 12 are mounted on the belt 9. A conveying assembly is mounted on the belt 9, comprising a motor 8 and a rotating roller 7. The purification assembly... The system includes a lower air duct 16 and an upper air duct 20. A blowing assembly, comprising a blower shroud 17 and air vents 18, is mounted on the top of the lower air duct 16. The upper air duct 20 is equipped with a filter assembly, including a suction shroud 19 and a filter cartridge 22. An anti-clogging component, comprising a roller 25 and a second motor 24, is mounted on the suction shroud 19. A cleaning component, comprising a screw plate 32 and a third motor 29, is mounted on the top of the machine body 1 by bolts. The detector 3 is bolted to the inner part of the top of the machine body 2. On the wall, the display 4 is bolted to the outer side of the casing 2. The detector 3 is an ultraviolet detector. A processor is installed inside the display 4. The material box 5 is bolted to the top of one side of the machine body 1. The feeding valve 6 is installed at the bottom of the material box 5 and is located at the top of the machine body 1. The rotating roller 7 is mounted on both sides of the machine body 1 via bearings. The motor 8 is bolted to the outer side of the machine body 1. One end of the rotating roller 7 is keyed to the output shaft of the motor 8. The belt 9 is sleeved on the outer sides of both ends of the rotating roller 7. The slide plate 1... The rotating rod 11 is bolted to the inside of the machine body 1. Both ends of the rotating rod 11 are mounted to the inside of the belt 9 via rotating shafts. The chuck 12 is mounted to the inside of the belt 9 via rotating shafts. One side of the chuck 12 is clamped to the outside of the rotating rod 11. The other side of the chuck 12 passes through the belt 9 and is clamped to the top of the slide plate 10. The bottom of the other side of the material box 5 is bolted to a slanted sleeve 13. The inside of the slanted sleeve 13 is clamped to a shovel plate 14. The bottom of the shovel plate 14 extends to the top of the rotating rod 11. The top of the shovel plate 14 is connected to the inner wall of the slanted sleeve 13 via a spring 15.

[0022] Understandably, peanuts are poured into the inside of the feed hopper 5, and then the motor 8 and the discharge valve 6 are turned on. The motor 8 drives the belt 9 via the rotating roller 7, and the belt 9 drives the rotating rod 11 and the chuck 12 to rotate clockwise. The bottom of the chuck 12 rotates clockwise due to friction with the slide plate 10. The chuck 12, through friction with the rotating rod 11, drives the rotating rod 11 to rotate counterclockwise. The peanuts fall onto the slide plate 10 through the discharge valve 6 and are then pushed to the right by the rotating rod 11. At the same time, the counterclockwise rotation of the rotating rod 11 causes the peanuts to rotate clockwise on the slide plate 10, preventing the peanuts from getting stuck between the rotating rod 11 and the slide plate 10. The shovel 14 slides and removes excess peanuts, ensuring that the peanuts move in a single layer on top of the slide plate 10. The shovel 14 can move inside the inclined sleeve 13 via the spring 15, preventing the shovel 14 from damaging the peanuts and thus ensuring their integrity and quality. This allows each peanut to roll from the bottom of the housing 2 under the push of the rotating rod 11, enabling the detector 3 to effectively perform comprehensive testing on each peanut. This avoids any omissions due to peanuts being obstructed by themselves or other substances, ensuring the effectiveness of the peanut testing.

[0023] like Figure 4 , Figure 5 and Figure 6 As shown, the lower air duct 16 is bolted to the bottom of the machine body 1, and the top of the lower air duct 16 is clipped to the outer side of the bottom of the rotating rod 11. The top of the blower shroud 17 is welded to the bottom of the slide plate 10. The air hole 18 is opened on the inner side of the slide plate 10. The bottom of the blower shroud 17 is clipped to the outer side of the top of the rotating rod 11. The blower shroud 17 is connected to the top of the slide plate 10 through the air hole 18. The filter cartridge 22 is bolted to the top of the machine housing 2. The top of the upper air duct 20 is bolted to one end of the filter cartridge 22. The suction shroud 19 is bolted to the bottom of the upper air duct 20. The suction shroud 19 is located on top of the blower shroud 17. Fans 21 are bolted to the inner sides of both the duct 20 and the lower duct 16. A mesh 23 is bolted to the inner side of the suction hood 19. The second motor 24 is bolted to the other side of the suction hood 19. A lead screw 27 is mounted on the output shaft of the second motor 24. One end of the lead screw 27 is mounted on one side of the suction hood 19 via a rotating shaft. A support block 26 is sleeved on the outer side of the lead screw 27. Both ends of the roller 25 are mounted on the support block 26 via rotating shafts. The roller 25 is clamped at the bottom of the mesh 23. A protrusion is integrally formed on the roller 25. The protrusion passes through the mesh 23 and extends to the top of the mesh 23. The protrusion is evenly distributed on the roller 25.

[0024] Understandably, the fan 21 inside the lower air duct 16 blows air into the inside of the blower hood 17, and then blows it upwards through the air holes 18, causing the peanut skins and other impurities that have already fallen off the peanuts to be blown upwards. The fan 21 inside the upper air duct 20 generates suction on the suction hood 19, sucking the peanut skins and other impurities into the inside of the upper air duct 20, where they are then filtered out by the filter cartridge 22. The partition screen 23 prevents the peanuts from being blown into the inside of the upper air duct 20 due to a sudden increase in local airflow. When a large peanut skin gets stuck at the bottom of the partition screen 23, the motor 24 pushes the support block 26 through the lead screw 27. The roller 25 moves back and forth at the bottom of the mesh 23, and through the protrusions, it breaks or pushes the peanut skins adsorbed at the bottom of the mesh 23 into the inner side of the upper air duct 20. Then, it is carried by the airflow to the inner side of the filter cylinder 22 for filtration. This effectively cleans the peanut skins and other impurities, while preventing the peanut kernels from being accidentally cleaned. It also prevents peanut skins with a diameter larger than the peanut kernels from clogging the mesh 23, ensuring ventilation efficiency and thus ensuring the cleaning effect of peanut skins and other impurities. This avoids interference with the detection of peanut kernels and improves the quality of the peanut kernels.

[0025] like Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a support sleeve 28 is bolted to the other end of the filter cartridge 22. A motor 29 is bolted to the outer side of the support sleeve 28. A main shaft 30 is mounted on the output shaft of the motor 29. One end of the main shaft 30 passes through the support sleeve 28 and extends to the inner side of the filter cartridge 22. A fan blade 31 is bolted to one end of the main shaft 30. The outer side of the screw plate 32 is clamped onto the inner wall of the filter cartridge 22. The screw plate 32 is mounted on the outer side of the main shaft 30 via a support rod. A protrusion 33 is welded to the other end of the main shaft 30. The protrusion 33 is located inside the support sleeve 28. Buttons 34 are bolted to the top and bottom of the support sleeve 28. Rollers 35 are mounted on the buttons 34. One-way valves 36 are mounted on the buttons 34. The inside of the buttons 34 is connected to the outside of the buttons 34 in one direction through the one-way valves 36. A box 37 is bolted to the bottom of the other end of the filter cartridge 22. An opening is provided at the bottom of the other end of the filter cartridge 22. The filter cartridge 22 is connected to the box 37 through the opening. A side door is mounted on the box 37.

[0026] Understandably, the airflow causes the fan blades 31 to rotate. The fan blades 31, via the main shaft 30, drive the screw plate 32, scraping and cleaning the peanut skins and other impurities filtered into the filter cartridge 22. This continues until the screw plate 32 scrapes the peanut skins and other impurities through the opening to the inside of the housing 37, effectively cleaning the filter cartridge 22 and preventing clogging. As the main shaft 30 rotates, it continuously pushes the roller 35 through the protrusion 33. The roller 35 then presses the button 34, causing the air inside the button 34 to be discharged through the one-way valve 36. After the protrusion 33 loses its pressure on the roller 35, the negative pressure created inside the button 34 causes air to slowly enter the inside of the button 34 through the gaps, thus slowly resetting the button 34. Before the button 34 resets... The roller 35 is squeezed again by the protrusion 33. When the screw plate 32, main shaft 30 and other mechanisms are subjected to greater resistance or mechanical friction due to peanut skin and other impurities, resulting in slow rotation speed or even no rotation, the protrusion 33 cannot squeeze and push the roller 35 in time, thus causing the button 34 to reset, the motor 39 to be powered on and work, thereby driving the main shaft 30 to rotate. The main shaft 30 drives the fan blade 31 and screw plate 32 to rotate, which can not only improve the suction and ensure the absorption effect of peanut skin and other impurities, but also improve the cleaning speed of the screw plate 32 and ensure the cleaning efficiency of the filter cartridge 22. It can automatically perform non-powered cleaning work or switch to electric cleaning work according to the resistance of the fan blade 31, screw plate 32, main shaft 30 and other mechanisms, which can not only ensure the cleaning effect of the filter cartridge 22, but also save working energy.
