Technical Field

[0001] The utility model relates to the field of meat products, in particular to a Salmonella detection device based on a biosensor. Background Technique

[0002] Salmonella is a common foodborne pathogenic bacterium. The traditional methods for Salmonella identification mainly rely on morphological characteristics, cultural characteristics, physiological and biochemical characteristics, antigenic characteristics, phage characteristics, etc. In 1885, Salmonella et al. isolated Salmonella choleraesuis during a cholera epidemic, so it was named the genus Salmonella. Some species in the genus Salmonella are specifically pathogenic to humans, some are only pathogenic to animals, and some are pathogenic to both humans and animals.

[0003] Currently, Salmonella can be transmitted through two ways: vertical transmission and horizontal transmission. The transmission speed is fast and the range is wide, causing huge economic losses to the food industry. Due to problems such as antibiotic resistance and lack of vaccines, culling and purification are currently the main measures for preventing and controlling Salmonella. Rapid detection and discovery of Salmonella are becoming increasingly important for health issues. Therefore, the utility model proposes a Salmonella detection device based on a biosensor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0021] Referring toFigures 1-6 As shown in the figure, a Salmonella detection device based on a biosensor includes a box body 1. A partition 2 is fixedly installed on the inner wall of the box body 1. The partition 2 divides the interior of the box body 1 into a first chamber 3 and a second chamber 4. The first chamber 3 is located above the second chamber 4. A telescopic mechanism 5 is fixedly installed on the upper surface of the partition 2. The telescopic mechanism 5 drives the extracted sample into the first chamber 3 and pushes the sample to make the sample to be detected enter the second chamber 4. A sample storage mechanism 6 is arranged on the upper surface of the partition 2. The sample storage mechanism 6 stores the samples to be detected that have not been tested yet. A first lead screw 7 is rotatably installed on the upper surface of the partition 2 corresponding to the sample storage mechanism 6. A second fixture 8 is sleeved on the outer surface of the first lead screw 7. A slide rail 9 is fixedly installed at the bottom of the inner wall of the second chamber 4. A plurality of detectors 10 are slidably installed inside the slide rail 9. The plurality of detectors 10 are linearly distributed along the rail body of the slide rail 9. The sample that enters the second chamber 4 enters the detectors 10, and the detectors 10 detect the material.

[0022] As Figure 4 shown in the figure, a moving mechanism 11 is fixedly installed on the bottom surface of the box body 1. The moving mechanism 11 is of a crawler type, which helps to improve the stability during its driving process and reduce the risk of tipping over. A manipulator 12 is fixedly installed at the center of the upper surface of the box body 1. The manipulator 12 grabs the cotton swab and makes the cotton swab contact with the pork to be detected, thereby completing the extraction of the sample. A first through groove 13 corresponding to the telescopic mechanism 5 is penetrated through the upper surface of the box body 1 corresponding to the manipulator 12. A first fixture 14 is fixedly installed on the upper surface of the box body 1 corresponding to the first through groove 13. The first fixture 14 is used to clamp the detected sample after extraction. A placement plate 15 is fixedly installed on the upper surface of the box body 1. A plurality of placement grooves 16 are formed on the surface of the placement plate 15. The plurality of placement grooves 16 are linearly distributed along the length direction of the placement plate 15. A second through groove 17 corresponding to the sample storage mechanism 6 is penetrated through the upper surface of the box body 1 corresponding to the placement plate 15. A packaging disassembler 18 is fixedly installed on the upper surface of the box body 1 corresponding to the second through groove 17. The packaging disassembler 18 can closely fit a part of the packaging. When the vacuum pump is started, the air in the chamber will be quickly pumped out to form a negative pressure environment in the chamber, and the adsorption force is used to tear open the sealing part of the packaging, realizing the efficient and rapid completion of the unpacking process and preventing the staff from contacting the cotton swab.

[0023] As Figure 5As shown, the telescopic mechanism 5 includes a first baffle 19. A connection groove 20 is penetrated and opened inside the first baffle 19. The first baffle 19 is fixedly connected to the upper surface of the partition plate 2. Two first connecting plates 21 are fixedly installed on the outer surface of the first baffle 19. The two first connecting plates 21 are symmetrically distributed about the center line of the first baffle 19. Two first connecting rods 22 are hinge-mounted inside the first connecting plate 21, and the two first connecting rods 22 are rotatably connected to each other. The two ends of the two first connecting rods 22 away from the connecting rod are both hinge-mounted with second connecting rods 23, and the two second connecting rods 23 are hinge-connected to each other. The two ends of the two second connecting rods 23 away from the first connecting rods 22 are both fixedly installed with sliding rods 24. A second connecting plate 25 is sleeved on the outer surface of the sliding rod 24. A second baffle 26 corresponding to the first baffle 19 is fixedly installed on one side of the two second connecting plates 25 close to each other. The rotation of the two first connecting rods 22 causes the two second connecting rods 23 to rotate, and further causes the second baffle 26 to move. A top rod 27 corresponding to the connection groove 20 is fixedly installed on the bottom surface of the second baffle 26. After the sample to be detected enters the connection groove 20, the second baffle 26 moves downward, and the top rod 27 pushes the sample to be detected to move along the connection groove 20.

[0024] As Figure 5 shown, third connecting rods 28 are hinge-mounted in the middle of the two first connecting rods 22. The ends of the two third connecting rods 28 away from the first connecting rods 22 are connected by a support shaft 29. A telescopic driving rod 30 is fixedly installed at the end of the support shaft 29 away from the third connecting rod 28. The telescopic driving rod 30 controls the rotation of the third connecting rod 28 through telescoping. Since the third connecting rod 28 and the first connecting rod 22 form a rhombus quadrilateral, the first connecting rod 22 is rotated.

[0025] As Figure 6 shown, the sample storage mechanism 6 includes a fixing plate 31. A second lead screw 32 is rotatably installed on the upper surface of the fixing plate 31. A slide plate 33 is sleeved on the outer surface of the second lead screw 32. A plurality of memory devices 34 are arranged on the upper surface of the slide plate 33. The plurality of memory devices 34 are circumferentially distributed about the center line of the second lead screw 32. The memory devices 34 correspond to the second fixture 8. The second lead screw 32 rotates to make the slide plate 33 move along the axial direction of the second lead screw 32, and further makes the memory devices 34 move upward to store the sample rods that have not been collected. A sleeve 35 is sleeved on the outer surface of the second lead screw 32, and the sleeve 35 is rotatably connected to the fixing plate 31. A circular plate 36 is fixedly installed at the upper end of the sleeve 35. A guide rod 37 corresponding to the memory device 34 is fixedly installed on the upper surface of the circular plate 36. The guide rod 37 is slidably connected to the slide plate 33. When the second fixture 8 clamps the sample rod in the target memory device 34, the sleeve 35 rotates to drive the guide rod 37 on the circular plate 36 to drive the slide plate 33 to rotate, so that the target memory device 34 corresponds to the second fixture 8.

[0026] AsFigure 3 As shown, a conduit 38 corresponding to the connection groove 20 is fixedly installed on the bottom surface of the partition plate 2, and the conduit 38 communicates with the connection groove 20. The conduit 38 corresponds to the detector 10. The conduit 38 facilitates ensuring that the sample can enter the detection process smoothly and quickly, improving the detection efficiency. By transmitting the sample through the closed conduit 38, the contact between the sample and the external environment during transmission can be reduced, thereby reducing the risk of contamination.

[0027] Working principle: The packaging disassembler 18 opens the packaging bag containing the packaging bag and places the cotton swab in the placement groove 16. At the same time, the robotic arm and the second fixture 8 cooperate with each other to make the corresponding sample test rod enter the memory 34. After the moving mechanism 11 drives the device to move to a suitable position, the robotic arm grabs the cotton swab and contacts the cotton swab with the pork to be detected. After the extraction is completed, the sample is placed in the first baffle 19. The telescopic drive rod 30 controls the rotation of the third connecting rod 28 through telescoping. The third connecting rod 28 drives the first connecting rod 22 to rotate, so that the second connecting rod 23 drives the second baffle rod to move downward. The ejector rod 27 on the second baffle 26 pushes the sample to be detected along the conduit 38 into the detector 10, and the detector 10 detects the sample.
