Description

Technical Field

[0001] The present invention relates to the technical field of mercury content detection, and specifically to a detection device for mercury content in beef. Background Art

[0002] With the increasing demand for beef in life, the breeding and slaughter industries of beef cattle have developed rapidly. Due to the different scales of farmers and environmental pollution, the quality of meat products produced by slaughter enterprises is very unstable. Each meat product production enterprise is actively exploring and establishing its own detection system to ensure the safety of its products. In the national health standard for beef products, there are strict limits on mercury content. The mercury content in beef should not be greater than 0.05 mg / KG. Therefore, the detection of mercury content is particularly important.

[0003] At present, the detection method for mercury content in beef is to mix diphenylcarbazide ethyl ether solution and OP aqueous solution of emulsifier in proportion, impregnate medium-speed quantitative filter paper to make test paper. Take 1000 μg / mL standard mercury solution, adjust the pH to 6.0 with HCl solution, dilute with water to a solution with a mercury content of 0.5 μg / mL, put the test paper in it, develop color, take a photo, and form a paper standard color scale after processing. Weigh the beef sample, add 10% HCl after crushing, microwave digestion, centrifuge to take the supernatant, adjust the pH value to 6.0, concentrate under reduced pressure to 1 / 10 of the sample weight, put the test paper in it to develop color and take a photo. Compare the color development depth of the test paper with the standard color scale to judge whether the mercury content exceeds the standard.

[0004] In the above technical method, it is necessary to manually insert the processed beef sample solution into the test paper, and then perform colorimetry on the test paper to detect the mercury content. In this technology, it needs to be done one by one manually. When the number of samples is large, the manual processing efficiency is low, and when the number of samples is large, it is easy to get confused under manual operation, resulting in inaccurate detection of the mercury content of the samples.

[0019] 3. In the present invention, through the rotation of the screw, the cooperation between the first push plate and the screw can slowly push the collection tube in the conveying frame into the placement table. This process can be accompanied by the receiving of the merged collection tubes by the sending-out frame. Through the movement of the first push plate, the pull rope pulls the second push plate to move backward along the moving frame to limit the incoming collection tubes and keep them tightly arranged inside the sending-out frame.

[0020] 4. Compared with the prior art, in the present invention, through the cooperation of the merging component and the sealing component, the collection tubes of multiple groups of samples are inserted into the test strips one by one, sealed and waited, and then sent to the sending-out frame in a row, which is convenient for uniformly taking out the test strips from the collection tubes and comparing and photographing them with the colorimetric plate for collection.

The output end of the motor 21 is fixedly connected to the placement table 23. A plurality of groups of slots are equidistantly arranged on the outer edge of the placement table 23. An elastic rubber layer is arranged inside the slots of the placement table 23. A retaining frame 22 is wrapped around the outer edge of the placement table 23, and the retaining frame 22 is fixed on the surface of the detection table 1. An inlet 24 is arranged on the surface of the retaining frame 22 corresponding to the slots, and a delivery outlet 25 is arranged on one side of the retaining frame 22 where the inlet 24 is located. A conveying frame 3 is fixed at the position corresponding to the inlet 24 on the detection table 1, and a delivery frame 4 is fixed at the position corresponding to the delivery outlet 25 on the detection table 1. A collection tube 7 is placed inside the delivery frame 4, the conveying frame 3 and the slots of the placement table 23. A detection component 6 is arranged on the top of the delivery frame 4. The detection component 6 includes a camera 64. A camera 64 is arranged at the top of one side of the delivery frame 4, and a colorimetric plate 63 is arranged at the top of the other side of the delivery frame 4. A sealing component 5 is arranged on the top of the placement table 23. The sealing component 5 includes a connecting frame 55. Installation plates 51 are fixed at both ends of the connecting frame 55. A plurality of groups of cover plates 52 are symmetrically arranged on the surface of the installation plates 51 with the center of the circle, and the positions of the cover plates 52 correspond to the collection tubes 7. A spring clip 53 is fixed at the bottom of the cover plate 52, and a test strip 54 is clamped inside the spring clip 53. When using the device, the centrifuged beef sample solution is placed inside the collection tube 7. Different samples are placed in different collection tubes 7. They are sent into the inside of the placement table 23 through the conveying frame 3. Through the cooperation of the merging component 2 and the sealing component 5, a test strip 54 is inserted into each collection tube 7 and sealed and covered by the cover plate 52. Finally, they are sent into the delivery frame 4 one by one from the placement table 23. The test strip 54 is uniformly colorimetric and photographed by the detection component 6.

[0032] In this embodiment, a moving groove 32 is formed in the inner wall of the bottom of the conveying frame 3, and a screw rod 33 is installed in the moving groove 32 through a bearing and a motor. A first push plate 31 is threadedly sleeved on the surface of the screw rod 33. The first push plate 31 slides along the inside of the conveying frame 3, and the first push plate 31 is in pressing contact with the last collecting pipe 7. A second push plate 42 is slidably installed inside the sending frame 4. A pulling rope 41 is fixed to the bottom of the second push plate 42. The other end of the pulling rope 41 passes through the sending frame 4 and the conveying frame 3 and is fixedly connected to the first push plate 31. When the screw rod 33 rotates, the cooperation between the first push plate 31 and the screw rod 33 can slowly push the collecting pipe 7 in the conveying frame 3 into the placing table 23. This process can be accompanied by the sending frame 4 receiving the collected pipes 7 that have been combined. Through the movement of the first push plate 31, the pulling rope 41 pulls the second push plate 42 to move backward along the moving frame, limiting the incoming collecting pipes 7 and keeping them closely arranged inside the sending frame 4.

[0033] In this embodiment, the sealing assembly 5 further includes a spring telescopic rod 56. The bottom of the middle position of the connecting frame 55 is fixed with a spring telescopic rod 56, and the bottom of the spring telescopic rod 56 is rotatably installed on the outer surface of the retaining frame 22 through a bearing seat. The top of the center of the connecting frame 55 is rotatably installed with a fifth electric push rod 510 through a bearing, and a top plate 58 is fixed to the extending end of the fifth electric push rod 510. A top post 59 is fixed to the top plate 58 corresponding to the position of the upper cover plate 52 of the mounting plate 51. The fifth electric push rod 510 and the retaining frame 22 are fixedly connected through a telescopic connecting plate. The center of the placing table 23 is rotatably installed with a first electric push rod 29 through a bearing seat. An arc-shaped jack is opened at the top of the first electric push rod 29. An arc block 211 is fixed to the center of the bottom of the mounting plate 51. The two arc blocks 211 alternately insert from both sides of the jack of the first electric push rod 29. A first gear 26 is fixed to the bottom of the placing table 23. A second gear 27 is meshed with one side of the first gear 26. The second gear 27 is rotatably installed outside the retaining frame 22 through a bearing seat, and a cross-shaped socket 28 is fixed to the top of the second gear 27. A fourth electric push rod 57 is fixed to the bottom of the spring telescopic rod 56, and a cross-shaped plug is fixed to the extending end of the fourth electric push rod 57. The extending end of the fourth electric push rod 57 is slidably inserted into the socket 28. During the stage of feeding the collection tube 7, the extending end of the fourth electric push rod 57 is separated from the socket 28. Thus, the rotation of the motor 21 will not drive the rotation of the connecting frame 55. Align the slots on the placing table 23 with the inlets 24 one by one to receive new collection tubes 7. After the slots on the placing table 23 are filled with collection tubes 7, the extending end of the first electric push rod 29 is inserted into the arc block 211 at the bottom of a group of mounting plates 51 to pull it down, and the test strip 54 is inserted into the corresponding collection tube 7. During this process, the spring telescopic rod 56 contracts to keep the connecting frame 55 and the mounting plate 51 moving down together. After the cover plate 52 covers the collection tube 7, the connecting frame 55 is raised to its original position, and the extending end of the fourth electric push rod 57 is inserted into the socket 28. This insertion method is the common insertion method of a cross-shaped plug and a socket, which is not shown in the figure. When the motor 21 continues to drive the placing table 23 to rotate and send out the combined collection tubes 7 and the cover plate 52, the first gear 26 is meshed with the second gear 27, and the second gear 27 drives the entire combining assembly 2 to rotate to replace the positions of the two groups of mounting plates 51, and insert the arc block 211 of the other group of mounting plates 51 into the jack of the first electric push rod 29. The jack at the extending end of the first electric push rod 29 is semi-hollowed out, and the arc block 211 can pass through the jack or be inserted into the jack. When the first electric push rod 29 retracts, it drives the mounting plate 51 to descend together. Due to the semi-hollow structure of the jack, the two mounting plates 51 can rotate continuously until the placing table 23 stops, and surely an arc block 211 at the bottom of one group of mounting plates 51 will be inserted into the jack.

[0034] In this embodiment, the detection component 6 also includes an electric slide rail 61, the side of the delivery frame 4 is fixed with the electric slide rail 61, and a mobile frame 62 is slidably installed on the surface of the electric slide rail 61, the camera 64 and the colorimetric plate 63 are fixed on the top of the mobile frame 62, the surface of the connecting frame 55 is hollowed out, and magnet blocks 511 are fixed on both sides of the cover plate 52, the mounting plate 51 is provided with a metal groove at the position corresponding to the magnet block 511 of the cover plate 52, and the cover plate 52 is adsorbed on the mounting plate 51 through the magnet block 511, and the bottom of the cover plate 52 is located at the spring A rubber plug is provided on the periphery of the clamp 53, a push frame 44 is provided on the top of the delivery frame 4, and a third electric push rod 43 is fixed to the tail end of the delivery frame 4, and the extended end of the third electric push rod 43 is fixedly connected to the push frame 44, and the hollowing out of the surface of the connecting frame 55 will not affect the extrusion contact of the top column 59 on the cover plate 52, and the cover plate 52 is adsorbed and installed on the mounting plate 51 through the magnet block 511. After the mounting plate 51 covers the upper end of the collection tube 7 and the cover plate 52 is inserted into the pipe mouth of the collection tube 7 through the rubber plug, the top plate 58 and the top column 59 are driven to move by the fifth electric push rod 510. The cover plate 52 is pushed out of the mounting plate 51, plugged into the collecting tube 7 separately, and then sent out together. During the whole process, the sealing of the collecting tube 7 and the test paper 54 are kept inserted in the collecting tube 7. After the detection is completed, the cover plate 52 is uniformly recovered, and the test paper 54 can be replaced and continued to be used through the spring clip 53. After the combined collecting tube 7 enters the sending frame 4, the third electric push rod 43 drives the push frame 44 to move up. The push frame 44 is made of metal and is in adsorption contact with the magnet blocks 511 on both sides of the cover plate 52. Although there is a rubber plug at the bottom of the cover plate 52, it will not The collecting tube 7 has a strong squeezing force, so when the push frame 44 drives the cover plate 52 to move upward, it will not move upward together with the collecting tube 7. The test paper 54 is taken out of the collecting tube 7 and positioned between the camera 64 and the colorimetric plate 63 for colorimetric and photographic collection. Driven by the electric slide rail 61, the movable frame 62 moves horizontally along the electric slide rail 61, and the camera 64 and the colorimetric plate 63 move along the route of the delivery frame 4. All the test papers 54 are compared and photographed one by one in order to avoid confusion. The electric slide rail 61 can be driven by a common screw.

[0035] In this embodiment, a second electric push rod 210 is fixed transversely to the outer side of the first electric push rod 29 at a position corresponding to the delivery outlet 25, and the second electric push rod 210 is in squeeze contact with the collection tube 7 at the delivery outlet 25. When the test paper 54 is inserted, the cover plate 52 covers the collection tube 7 and rotates to the delivery outlet 25, the second electric push rod 210 pushes the collection tube 7 out of the slot of the placement table 23 and into the delivery frame 4, which is convenient for subsequent unified photography and color card comparison.

[0036] When using the device, place the centrifuged beef sample solution into the inside of the collection tube 7. Different samples are placed in different collection tubes 7. The screw 33 rotates, and the cooperation between the first push plate 31 and the screw 33 can slowly push the collection tube 7 in the conveying frame 3 into the placement table 23. During this process, the sending-out frame 4 can receive the combined collection tube 7. Through the movement of the first push plate 31, the pull rope 41 pulls the second push plate 42 to move backward along the moving frame, limiting the incoming collection tube 7 and keeping it closely arranged inside the sending-out frame 4. During the stage of feeding the collection tube 7, the extended end of the fourth electric push rod 57 is separated from the socket 28. Thus, the drive of the motor 21 will not drive the rotation of the connecting frame 55. Align the slots on the placement table 23 with the inlets 24 one by one to receive new collection tubes 7. After the slots on the placement table 23 are filled with collection tubes 7, the extended end of the first electric push rod 29 is inserted into the arc-shaped block 211 at the bottom of a group of mounting plates 51, pulling it down, and inserting the test paper 54 into the corresponding collection tube 7. During this process, the spring telescopic rod 56 contracts to keep the connecting frame 55 and the mounting plate 51 moving downward together. After the cover plate 52 covers the collection tube 7, raise the connecting frame 55 to its original position. The extended end of the fourth electric push rod 57 is inserted into the socket 28. This insertion method is the common insertion method of a cross-shaped plug and a slot, not shown in the figure. When the motor 21 continues to drive the placement table 23 to rotate and send out the combined collection tube 7 and the cover plate 52, the first gear 26 meshes with the second gear 27, and the second gear 27 drives the entire combining assembly 2 to rotate, replacing the positions of the two groups of mounting plates 51. Insert the arc-shaped block 211 of the other group of mounting plates 51 into the jack of the first electric push rod 29. After the mounting plate 51 covers the upper end of the collection tube 7 and the cover plate 52 is inserted into the tube orifice of the collection tube 7 through a rubber plug, drive the top plate 58 and the top column 59 to move through the fifth electric push rod 510, pushing the cover plate 52 out of the mounting plate 51 and inserting it separately into the collection tube 7, and then sending them out together. During the whole process, the collection tube 7 is kept sealed and the test paper 54 is inserted inside the collection tube 7. After the detection is completed, the cover plate 52 is recycled uniformly. The test paper 54 can be replaced through the spring clip 53 and used continuously. After the combined collection tube 7 enters the sending-out frame 4, the third electric push rod 43 drives the push frame 44 to move upward. The push frame 44 is made of metal and is adsorbed and contacted with the magnet blocks 511 on both sides of the cover plate 52. Although there is a rubber plug at the bottom of the cover plate 52 here, it will not have a strong extrusion force on the collection tube 7. Therefore, when the push frame 44 drives the cover plate 52 to move upward, it will not move the collection tube 7 upward together. Take out the test paper 54 from the collection tube 7 and place it between the camera 64 and the colorimetric plate 63 for color comparison and photo collection. Driven by the electric slide rail 61, the moving frame 62 moves horizontally along the electric slide rail 61, and the camera 64 and the colorimetric plate 63 move along the route of the sending-out frame 4 to compare and photograph all the test papers 54 one by one in order to avoid confusion.
