Description

Technical Field

[0001] The present invention relates to the technical field of meat quality detection, and more particularly, to a Jinhua pig meat quality detection device and a detection method thereof. Background Art

[0002] Jinhua pigs, also known as two - headed black pigs or Jinhua two - headed black pigs, are livestock and poultry animals of the genus Sus in the family Suidae and are local breeds of Chinese pigs. Jinhua pigs are native to Jinhua City, Zhejiang Province and are distributed in towns such as Huashui and Nanshi in Dongyang City, Shangxi in Yiwu City, and Meijiang in Lanxi City. Jinhua pigs are suitable for curing high - quality hams and have good combining ability and heterosis when crossed with foreign - breed boars.

[0003] The detection of Jinhua pig meat quality mainly involves the detection of muscle pH value and water - holding capacity. The muscle pH value directly affects the tenderness, color, and water - holding capacity of the muscle. After animal slaughter, glycogen glycolysis in the muscle causes the muscle pH value to decrease. Water - holding capacity refers to the ability of muscle to retain water when subjected to external forces such as pressure, heating, freezing, and chopping. Water - holding capacity directly affects the color, flavor, tenderness, and nutritional value of meat. When the water - holding capacity is high, the meat is juicy, tender, and has a dry surface; when the water - holding capacity is low, water seeps out from the meat surface, and soluble nutrients and flavors are severely lost, the muscle becomes dry and hard, and the meat quality deteriorates.

[0004] The pH value of normal pork is about 6.3 after 45 minutes of slaughter, and then slowly drops to 5.5 after 5 - 12 hours. The reason for the drop is that muscle glycogen is decomposed into lactic acid. After 24 hours, the pH value remains unchanged for a certain period of time, and the length of this period depends on whether the carcass is cooled, the degree of bacterial contamination, and storage conditions. Since the pH value and water - holding capacity of muscle change over time, it is necessary for testers to regularly and at fixed points detect the pH value and water - holding capacity of Jinhua pig muscle. Missing the detection time or operating errors will affect the final meat quality detection results, increasing the workload of testers. Therefore, there is a need to realize automatic detection of Jinhua pig meat quality.

[0005] Therefore, how to realize automatic detection of Jinhua pig meat quality is an urgent problem to be solved in this technical field. Summary of the Invention

[0022] Example 1: like Figure 1 - Figure 2 As shown, this embodiment provides a Jinhua pork quality detection device, comprising: Box 1, inside which there are arranged a refrigerating chamber 11, a normal-temperature chamber 12, a pH chamber 13, a water-holding capacity chamber 14 and a recovery chamber 15. The box 1 is hermetically connected with a closed cover plate 16. A refrigerating device 18 is arranged inside the refrigerating chamber 11. An electric airtight door 17 is arranged between the refrigerating chamber 11 and the normal-temperature chamber 12; Conveyor 2, which penetrates through the normal-temperature chamber 12, the pH chamber 13, the water-holding capacity chamber 14 and the recovery chamber 15. A plurality of clamping seats 21 are drivingly connected to the conveyor 2; Docking mechanism 3, which is arranged inside the normal-temperature chamber 12. The docking mechanism 3 is drivingly connected with a plurality of meat samples I 31, and the meat samples I 31 are engaged with the clamping seats 21; Transfer mechanism 4, which is arranged inside the refrigerating chamber 11. The transfer mechanism 4 is drivingly connected with a plurality of meat samples II 41, and the meat samples II 41 are engaged with the clamping seats 21. The transfer mechanism 4 is used for conveying the meat samples II 41 onto the docking mechanism 3; pH value detection mechanism 5, which is arranged inside the pH chamber 13; Water-holding capacity detection mechanism 6, which is arranged inside the water-holding capacity chamber 14; Disassembly mechanism 7, which is arranged inside the recovery chamber 15. The disassembly mechanism 7 is used for disassembling the meat samples I 31 or the meat samples II 41 from the clamping seats 21; Controller 8, which is arranged on the box 1. The controller 8 is communicatively connected with the refrigerating device 18, the electric airtight door 17, the conveyor 2, the docking mechanism 3, the transfer mechanism 4, the pH value detection mechanism 5, the water-holding capacity detection mechanism 6 and the disassembly mechanism 7.

[0023] It is understandable that when detecting the meat quality of Jinhua pigs, after the Jinhua pigs are slaughtered, record the slaughter time and the feeding situation before slaughter. A long period of fasting and muscle movement before slaughter will deplete glycogen in the muscles and hardly produce lactic acid, resulting in a relatively high pH value. Take the longissimus dorsi muscle of the Jinhua pig after slaughter to make multiple cube meat samples 9 of equal size; place the multiple cube meat samples 9 on multiple meat sample plates I 31 and multiple meat sample plates II 41 respectively, and place the multiple meat sample plates I 31 carrying the cube meat samples 9 on the docking mechanism 3, and place the multiple meat sample plates II 41 carrying the cube meat samples 9 on the transfer mechanism 4; seal the closed cover plate 16 with the box body 1, and then set the refrigeration temperature of the refrigeration device 18 through the controller 8; based on the slaughter time, set the first detection time, the second detection time and the third detection time through the controller 8, where the first detection time is 45 minutes after slaughter, the second detection time is 12 hours after slaughter, and the second detection time is 24 hours after slaughter; set the first thawing time based on the second detection time, the first thawing time is 0.5 hour to 1 hour before the second detection time, set the second thawing time based on the third detection time, and the second thawing time is 0.5 hour to 1 hour before the third detection time; then start the controller 8 to enter the working state. When the first detection time is reached, the docking mechanism 3 pushes the first meat sample plate I 31 to engage with the card seat 21, and the conveyor 2 conveys the first meat sample plate I 31 into the pH chamber 13. The pH value of the cube meat sample 9 on the first meat sample plate I 31 is detected by the pH value detection mechanism 5. Then, the conveyor 2 conveys the first meat sample plate I 31 into the water holding capacity chamber 14, and the water holding capacity of the cube meat sample 9 on the first meat sample plate I 31 is detected by the water holding capacity detection mechanism 6. After the water holding capacity detection is completed, the conveyor 2 conveys the first meat sample plate I 31 into the recovery chamber 15, and the disassembly mechanism 7 disassembles the connection between the first meat sample plate I 31 and the card seat 21. The first meat sample plate I 31 and the cube meat sample 9 placed on it are recovered into the recovery chamber 15, and the controller 8 obtains the pH value and water holding capacity of the cube meat sample 9 at the first detection time; then when the first thawing time is reached, the controller 8 controls the electric closed door 17 to open, and the transfer mechanism 4 pushes the first meat sample plate II 41 into the docking mechanism 3. Then the controller 8 controls the electric closed door 17 to close, and the cube meat sample 9 on the first meat sample plate II 41 is thawed in the normal temperature chamber 12.

[0024] When the second detection time is reached, the docking mechanism 3 respectively pushes the second meat sample plate I 31 and the first meat sample plate II 41 to engage with different card seats 21. The conveyor 2 conveys the second meat sample plate I 31 and the first meat sample plate II 41 into the pH chamber 13. The pH value detection mechanism 5 sequentially detects the pH values of the cube meat samples 9 on the second meat sample plate I 31 and the cube meat samples 9 on the first meat sample plate II 41. Subsequently, the conveyor 2 conveys the second meat sample plate I 31 and the first meat sample plate II 41 into the water holding capacity chamber 14. The water holding capacity detection mechanism 6 sequentially detects the water holding capacities of the cube meat samples 9 on the second meat sample plate I 31 and the cube meat samples 9 on the first meat sample plate II 41. After the water holding capacity detection is completed, the conveyor 2 conveys the second meat sample plate I 31 and the first meat sample plate II 41 into the recovery chamber 15. The disassembly mechanism 7 disassembles the connections between the second meat sample plate I 31, the first meat sample plate II 41 and the card seats 21. The second meat sample plate I 31 and the cube meat samples 9 placed thereon, the first meat sample plate II 41 and the cube meat samples 9 placed thereon are recovered into the recovery chamber 15. The controller 8 obtains the pH values and water holding capacities of the cube meat samples 9 at normal temperature and the pH values and water holding capacities of the cube meat samples 9 under refrigeration at the second detection time. Subsequently, when the second thawing time is reached, the controller 8 controls the electric closed door 17 to open. The transfer mechanism 4 pushes the second meat sample plate II 41 into the docking mechanism 3. Subsequently, the controller 8 controls the electric closed door 17 to close. The cube meat samples 9 on the second meat sample plate II 41 are thawed in the normal temperature chamber 12.

[0025] When the third detection time is reached, the docking mechanism 3 respectively pushes the third meat sample plate I 31 and the second meat sample plate II 41 to engage with different card seats 21. The conveyor 2 conveys the third meat sample plate I 31 and the second meat sample plate II 41 into the pH chamber 13. The pH value detection mechanism 5 sequentially detects the pH values of the cube meat samples 9 on the third meat sample plate I 31 and the cube meat samples 9 on the second meat sample plate II 41. Subsequently, the conveyor 2 conveys the third meat sample plate I 31 and the second meat sample plate II 41 into the water holding capacity chamber 14. The water holding capacity detection mechanism 6 sequentially detects the water holding capacities of the cube meat samples 9 on the third meat sample plate I 31 and the cube meat samples 9 on the second meat sample plate II 41. After the water holding capacity detection is completed, the conveyor 2 conveys the third meat sample plate I 31 and the second meat sample plate II 41 into the recovery chamber 15. The disassembly mechanism 7 disassembles the connections between the third meat sample plate I 31, the second meat sample plate II 41 and the card seats 21. The third meat sample plate I 31 and the cube meat samples 9 placed thereon, the second meat sample plate II 41 and the cube meat samples 9 placed thereon are recovered into the recovery chamber 15. The controller 8 obtains the pH value and water holding capacity of the cube meat sample 9 at room temperature at the third detection time, and the pH value and water holding capacity of the cube meat sample 9 under refrigeration at the third detection time. After the detection cycle ends, the tester obtains the detection results of multiple cube meat samples 9 at room temperature and the detection results of multiple cube meat samples 9 under refrigeration through the controller 8. Subsequently, the meat sample plate I 31, the meat sample plate II 41 and the cube meat samples 9 in the recovery chamber 15 are taken out, and the refrigeration chamber 11, the room temperature chamber 12, the pH chamber 13, the water holding capacity chamber 14 and the recovery chamber 15 are cleaned for reuse.

[0026] In the above technical solution, the controller 8 automatically controls the electric closed door 17, the conveyor 2, the docking mechanism 3, the transfer mechanism 4, the pH value detection mechanism 5, the water holding capacity detection mechanism 6, and the disassembly mechanism 7, so that after the tester only prepares the cube meat sample 9, places the multiple meat sample plates I 31 carrying the cube meat sample 9 on the docking mechanism 3, places the multiple meat sample plates II 41 carrying the cube meat sample 9 on the transfer mechanism 4, and sets the detection time and thawing time based on the slaughter time. After the detection cycle ends, the detection results at multiple detection times at room temperature and the detection results at multiple detection times under refrigeration can be obtained, realizing the automatic detection of the quality of Jinhua pork.

[0027] It should be noted that the controller 8 includes a processing module, a collection module, a storage module, a control panel, and a timing module. The control panel is used to input the set detection time and thawing time into the timing module, and the control panel sets the refrigeration temperature of the refrigeration device 18 through the processing module. The storage module is used to store the execution parameters of the electric closing door 17, the conveyor 2, the docking mechanism 3, the transfer mechanism 4, the pH value detection mechanism 5, the water holding capacity detection mechanism 6, and the disassembly mechanism 7. The collection module collects the data information detected by the pH value detection mechanism 5 and the water holding capacity detection mechanism 6, and after processing the data information, transmits it to the storage module for storage. The processing module is used to start the electric closing door 17, the conveyor 2, the docking mechanism 3, the transfer mechanism 4, the pH value detection mechanism 5, the water holding capacity detection mechanism 6, and the disassembly mechanism 7 to perform tasks according to the execution parameters when the timing module reaches the set detection time or thawing time.

[0028] It should be noted that a high-definition camera is also provided in the pH chamber 13. The high-definition camera is communicatively connected to the controller 8. The high-definition camera is used to take pictures of the cubic meat sample 9 on the meat sample plate I 31 and / or the thawed cubic meat sample 9 on the meat sample plate II 41 after the meat sample plate I 31 and / or the meat sample plate II 41 enter the pH chamber 13, so as to obtain the meat color and marbling information at multiple detection times under normal temperature conditions and / or the meat color and marbling information at multiple detection times under refrigerated conditions.

[0029] The conveyor 2 drives a plurality of card seats 21 to circulate and move in the normal temperature chamber 12, the pH chamber 13, the water holding capacity chamber 14, and the recovery chamber 15.

[0030] As Figure 3 shown, the docking mechanism 3 includes: A base 32, the base 32 is connected in the normal temperature chamber 12. A linear chute 33 and a T-shaped chute I 34 are respectively provided at the top of the base 32. The vertical section of the T-shaped chute I 34 corresponds to the electric closing door 17. The linear chute 33 is slidably connected to the meat sample plate I 31, and the T-shaped chute I 34 is slidably connected to the meat sample plate II 41; A first electric push rod 35, the first electric push rod 35 is connected to the base 32. The first electric push rod 35 is drivingly connected to a first slider. The first slider is integrally provided with a first push plate 36, and the first push plate 36 is slidably connected to the linear chute 33; A second electric push rod 37, the second electric push rod 37 is connected to the base 32. The second electric push rod 37 is drivingly connected to a second slider. The second slider is integrally provided with a second push plate 38, and the second push plate 38 is slidably connected to the horizontal section of the T-shaped chute I 34.

[0031] It can be understood that multiple meat sample plates Ⅰ 31 carrying the cubic meat sample 9 slide in the linear chute 33, and multiple meat sample plates Ⅱ 41 carrying the cubic meat sample 9 are placed on the transfer mechanism 4. When the thawing time set by the controller 8 is reached, the electric sealed door 17 opens, and the transfer mechanism 4 pushes the meat sample plate Ⅱ 41 carrying the cubic meat sample 9 from the vertical section of the T-shaped chute Ⅰ 34 and slides it into the horizontal section of the T-shaped chute Ⅰ 34; when the detection time set by the controller 8 is reached, the electric push rod Ⅰ 35 pushes the push plate Ⅰ 36 to slide a set length in the linear chute 33 through the slider. The pushing of the push plate Ⅰ 36 causes the meat sample plate Ⅰ 31 at the frontmost position in the linear chute 33 to slide out of the linear chute 33 and snap into the card seat 21. When the next detection time is reached, the electric push rod Ⅰ 35 continues to push the push plate Ⅰ 36 to slide the next set length in the linear chute 33 until all the meat sample plates Ⅰ 31 in the linear chute 33 are pushed out; and when the detection time set by the controller 8 is reached, the electric push rod Ⅱ 37 pushes the push plate Ⅱ 38 to slide into the horizontal section of the T-shaped chute Ⅰ 34. Through the pushing of the electric push rod Ⅱ 37, after the push plate Ⅱ 38 pushes the meat sample plate Ⅱ 41 to slide out of the horizontal section of the T-shaped chute Ⅰ 34, it snaps into the card seat 21, and then the electric push rod Ⅱ 37 resets to wait for pushing the next meat sample plate Ⅱ 41.

[0032] As Figure 4 shown, the transfer mechanism 4 includes: A bottom plate 42, the bottom plate 42 is erected in the refrigeration chamber 11, the top end of the bottom plate 42 is provided with a T-shaped chute Ⅱ 43, the T-shaped chute Ⅱ 43 corresponds to the electric sealed door 17, and the meat sample plate Ⅱ 41 is slidably connected to the T-shaped chute Ⅱ 43; An electric push rod Ⅲ 44, the electric push rod Ⅲ 44 is connected to the bottom plate 42, the electric push rod Ⅲ 44 is drivingly connected with a slider Ⅲ, and the slider Ⅲ is integrally provided with a push plate Ⅲ 45, and the push plate Ⅲ 45 is slidably connected to the vertical section of the T-shaped chute Ⅱ 43; An electric push rod Ⅳ 46, the electric push rod Ⅳ 46 is connected to the bottom plate 42, the electric push rod Ⅳ 46 is drivingly connected with a push plate Ⅳ 47, and the push plate Ⅳ 47 is slidably connected to the horizontal section of the T-shaped chute Ⅱ 43.

[0033] It can be understood that multiple meat sample plates II 41 carrying the cubic meat samples 9 slide and are placed in the vertical section of the T-shaped chute II 43. When the thawing time set by the controller 8 is reached, the electric sealed door 17 is opened, and the electric push rod III 44 drives the push plate III 45 to slide a set length in the vertical section of the T-shaped chute II 43, so that the meat sample plate II 41 at the forefront in the vertical section of the T-shaped chute II 43 enters the horizontal section of the T-shaped chute II 43. Subsequently, the electric push rod IV 46 pushes the meat sample plate II 41 to slide along the horizontal section of the T-shaped chute II 43 through the push plate IV 47. After the meat sample plate II 41 slides out of the horizontal section of the T-shaped chute II 43, it is pushed and slides from the vertical section of the T-shaped chute I 34 to the horizontal section of the T-shaped chute I 34. Subsequently, the electric push rod IV 46 resets and the electric sealed door 17 closes, and the meat sample plate II 41 carrying the cubic meat sample 9 enters the normal temperature chamber 12 for thawing; when the next thawing time set by the controller 8 is reached, the electric push rod III 44 continues to push the push plate III 45 to slide the next set length in the linear chute 33, and the electric push rod IV 46 cooperates with the push plate IV 47 to push another meat sample plate II 41 from the horizontal section of the T-shaped chute II 43 to the horizontal section of the T-shaped chute I 34.

[0034] As Figure 5 shown, the pH value detection mechanism 5 includes: A two-degree-of-freedom component 51, the two-degree-of-freedom component 51 is arranged in the pH chamber 13, and the two-degree-of-freedom component 51 is used for translational adjustment and lifting adjustment; A pH detection probe 52, the pH detection probe 52 is arranged on the two-degree-of-freedom component 51, and the pH detection probe 52 is used to detect the cubic meat sample 9 on the meat sample plate I 31 or the meat sample plate II 41; A cleaning component 53, the cleaning component 53 is arranged in the pH chamber 13, and the cleaning component 53 is used to clean the pH detection probe 52 after detection.

[0035] It can be understood that when detecting the pH value of the cubic meat sample 9 on the meat sample plate I 31 or the cubic meat sample 9 on the meat sample plate II 41, after the two-degree-of-freedom component 51 drives the pH detection probe 52 to slide forward, the two-degree-of-freedom component 51 drives the pH detection probe 52 to descend, so that the pH detection probe 52 detects the pH value of the cubic meat sample 9 on the meat sample plate I 31 or the cubic meat sample 9 on the meat sample plate II 41. After the pH detection probe 52 detects the pH value of the cubic meat sample 9 on the meat sample plate I 31 or the cubic meat sample 9 on the meat sample plate II 41, the two-degree-of-freedom component 51 drives the pH detection probe 52 to rise, and drives the pH detection probe 52 to slide backward and reset to the cleaning component 53. Subsequently, the two-degree-of-freedom component 51 drives the pH detection probe 52 to descend again, and the cleaning component 53 cleans the detected pH detection probe 52 for the pH detection probe 52 to detect again.

[0036] It should be noted that the two-degree-of-freedom component 51 includes an electric translation stage, the movable seat of which is connected to a lifting translation stage I, and the pH detection probe 52 is arranged on the movable seat of the lifting translation stage I. The electric translation stage and the lifting translation stage I are both communicatively connected to the processing module of the controller 8, and the pH detection probe 52 is communicatively connected to the acquisition module of the controller 8.

[0037] like Figure 6 As shown, the cleaning component 53 includes: A liquid storage tank 531 is provided in the pH chamber 13 and is used to store cleaning liquid; a micro water pump 532 , wherein an input end of the micro water pump 532 is connected to the liquid storage tank 531 ; A plurality of spray heads 533 are mounted in the pH chamber 13 and connected to the output end of the micro water pump 532 via a pipe. The spray heads 533 are used to rinse the pH detection probe 52; The liquid collecting dish 534 is engaged and disposed in the pH chamber 13 . The liquid collecting dish 534 is located below the spray head 533 . The liquid collecting dish 534 is used to collect the cleaning liquid after rinsing.

[0038] It can be understood that after the pH detection probe 52 completes the pH value detection of the cubic meat sample 9, the two-degree-of-freedom component 51 drives the pH detection probe 52 to slide backward and descend, and the controller 8 controls the micro water pump 532 to start the set time. The micro water pump 532 draws the cleaning liquid in the liquid storage tank 531 and flows to the multiple spray heads 533. The cleaning liquid is sprayed out by the multiple spray heads 533 to rinse the pH detection probe 52 after the detection. The cleaning liquid after rinsing the pH detection probe 52 enters the liquid collection dish 534 for collection. After the detection cycle is over, the cleaning liquid in the liquid collection dish 534 is processed.

[0039] like Figure 7 - Figure 8 As shown, the hydraulic detection mechanism 6 includes: A lifting device 61, the lifting device 61 is arranged in the hydraulic chamber 14; A sealing cover 62 is drivingly connected to the lifting device 61. An annular sealing gasket 63 is provided at the bottom end of the sealing cover 62, and the annular sealing gasket 63 abuts against the top of the meat sample plate I 31 or the meat sample plate II 41. A one-way valve 64 is connected to the top of the sealing cover 62. An air intake pipe 65 is provided on the sealing cover 62, and the air intake pipe 65 is provided with a solenoid valve 66. A vacuum pump 67 , which is disposed in the hydraulic chamber and is in communication with the one-way valve 64 ; An intake passage 141 is provided to penetrate through one side of the water retention chamber 14, and a screen 142 is arranged in the intake passage 141; An outlet passage 143 is provided to penetrate through the other side of the water retention chamber 14, and a fan 144 is arranged in the outlet passage 143; A weighing assembly 68 is arranged in the water retention chamber 14, and the weighing assembly 68 is used to weigh the weight of the cube meat sample 9 before and after vacuum treatment.

[0040] It can be understood that when performing water-holding capacity detection on the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41, the controller 8 controls the weighing assembly 68 to weigh the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41, and obtains the initial weight of the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41. Subsequently, the controller 8 controls the lifting device 61 to drive the sealing cover 62 to descend by a set height, and controls the solenoid valve 66 to close, so that the annular sealing gasket 63 provided at the bottom end of the sealing cover 62 abuts against the top end of the meat sample plate I 31 or the meat sample plate II 41, and the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41 is sealed in the sealing cover 62. Subsequently, the controller 8 controls the vacuum pump 67 to start, and performs vacuum pumping on the sealing cover 62. The gas in the sealing cover 62 is discharged after passing through the one-way flow valve 64. After the vacuum pump 67 starts for a set duration, it is closed. After the cube meat sample 9 reaches the set duration in the vacuum environment, the controller 8 controls the solenoid valve 66 to open, and air enters the sealing cover 62 from the air inlet pipe 65. Subsequently, the controller 8 controls the lifting device 61 to drive the sealing cover 62 to rise and reset. For the cube meat sample 9 after vacuum pumping, moisture oozes out to the surface of the cube meat sample 9 due to the coefficient of force. The fan 144 in the air outlet channel 143 is in a continuous startup state, accelerating the air to enter the water-holding capacity chamber 14 from the air inlet channel 141 and then be discharged from the air outlet channel 143. By accelerating the air flow, the cube meat sample 9 on the meat sample plate I 31 or / and the cube meat sample 9 on the meat sample plate II 41 after vacuum pumping in the water-holding capacity chamber 14 is air-dried. By air-drying, the moisture oozing out on the surface of the cube meat sample 9 is removed. After the cube meat sample 9 on the meat sample plate I 31 or / and the cube meat sample 9 on the meat sample plate II 41 is air-dried for a set duration, the controller 8 controls the weighing assembly 68 to weigh the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41 again, and obtains the weight of the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41 after moisture oozes out. The acquisition module of the controller 8 calculates the water-holding capacity of the cube meat sample 9 based on the initial weight and the weight after moisture oozes out of the same cube meat sample 9. The water-holding capacity calculation formula is: water-holding capacity = weight after moisture oozes out / initial weight × 100%. After weighing is completed, the controller 8 controls the conveyor 2 to convey the meat sample plate I 31 or / and the meat sample plate II 41 into the recovery chamber 15.

[0041] It should be noted that the lifting device 61 includes a lifting and translation table II, and the lifting and translation table II is communicatively connected to the processing module of the controller 8.

[0042] As Figure 7 - Figure 8 shown, the weighing assembly 68 includes: Electric cylinder Ⅰ 681, the electric cylinder Ⅰ 681 is installed in the water holding capacity chamber 14, the electric cylinder Ⅰ 681 is located on one side of the conveyor 2, the electric cylinder Ⅰ 681 is connected with a push rod Ⅰ 682, and the push rod Ⅰ 682 is used to push the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 out of the clamping seat 21; Connecting seat 683, the connecting seat 683 is connected in the water holding capacity chamber 14, the connecting seat 683 is located on the other side of the conveyor 2, a U-shaped guide plate 684 is arranged at the top of the connecting seat 683, the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is in clearance fit with the U-shaped guide plate 684, and an installation groove is opened at the top of the U-shaped guide plate 684, and the installation groove is located inside the U-shaped guide plate 684; Pressure sensor, the pressure sensor is arranged in the installation groove, the pressure sensor is connected with a weighing plate 685, and the top of the weighing plate 685 is arranged parallel to the top of the connecting seat 683; Electric cylinder Ⅱ 686, the electric cylinder Ⅱ 686 is connected to the connecting seat 683, the electric cylinder Ⅱ 686 is drivingly connected with a push plate Ⅴ 687, and the push plate Ⅴ 687 is arranged in the U-shaped guide plate 684 in clearance fit.

[0043] It can be understood that when weighing the weight after water seepage or the initial weight of the cubic meat sample 9 on the meat sample plate Ⅰ 31 or the cubic meat sample 9 on the meat sample plate Ⅱ 41, the controller 8 controls the electric cylinder Ⅰ 681 to extend. After the electric cylinder Ⅰ 681 extends, the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is pushed out of the clamping seat 21 by the push rod Ⅰ 682. Subsequently, the electric cylinder Ⅰ 681 retracts and returns to its original position. The meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is pushed out of the clamping seat 21 and enters the U-shaped guide plate 684, and the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is located on the weighing plate 685. The total weight of the meat sample plate Ⅰ 31 and the cubic meat sample 9 or the total weight of the meat sample plate Ⅱ 41 and the cubic meat sample 9 is measured by the pressure sensor. After the acquisition module of the controller 8 acquires the weight information, the controller 8 controls the electric cylinder Ⅱ 686 to extend. After the electric cylinder Ⅱ 686 extends, the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is pushed by the push plate Ⅴ 687, so that the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is pushed from the U-shaped guide plate 684 into the clamping seat 21. Subsequently, the electric cylinder Ⅱ 686 retracts and returns to its original position.

[0044] It should be noted that multiple meat sample plates Ⅰ 31 and multiple meat sample plates Ⅱ 41 are all standard parts, and the weights and shapes of multiple meat sample plates Ⅰ 31 and multiple meat sample plates Ⅱ 41 are the same. The weight information of the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41 is stored in the controller 8. After the acquisition module of the controller 8 acquires the data information of the pressure sensor, the initial weight or the weight after water seepage of the cubic meat sample 9 is obtained by subtracting the weight of the cubic meat sample 9 from the meat sample plate Ⅰ 31 or the meat sample plate Ⅱ 41.

[0045] As shown Figure 9 in the figure, the disassembly mechanism 7 includes: An electric cylinder III 71 is installed in the recovery chamber 15. The electric cylinder III 71 is arranged corresponding to the card seat 21. The electric cylinder III 71 is connected with a push rod II 72, and the push rod II 72 is used to push the meat sample plate I 31 or the meat sample plate II 41 out of the card seat 21; A recovery dish 73 is arranged in the recovery chamber 15, and the recovery dish 73 is used to collect the meat sample plate I 31, the meat sample plate II 41 and the cube meat sample 9.

[0046] It can be understood that when the controller 8 controls the conveyor 2 to drive the meat sample plate I 31 or the meat sample plate II 41 to enter the set position in the recovery chamber 15, the controller 8 controls the electric cylinder III 71 to extend. After the electric cylinder III 71 extends, the meat sample plate I 31 or the meat sample plate II 41 is pushed out of the card seat 21 by the push rod II 72. Then the electric cylinder III 71 retracts to its original position, and the meat sample plate I 31 or the meat sample plate II 41 and the cube meat sample 9 on the meat sample plate I 31 or the cube meat sample 9 on the meat sample plate II 41 fall into the recovery dish 73 for collection. After the detection period ends, the meat sample plate I 31, the meat sample plate II 41 and the cube meat sample 9 in the recovery dish 73 are processed.

[0047] As shown Figure 10 in the figure, a plurality of limiting columns 311 are integrally arranged at the top end of the meat sample plate I 31. The limiting columns 311 are used for fitting and engaging with the shape of the cube meat sample 9, so that the cube meat sample 9 is fixed at a specified position on the meat sample plate I 31. The meat sample plate II 41 has the same structure as the meat sample plate I 31.

[0048] It can be understood that during the automatic detection of the cube meat sample 9, in order to ensure the detection accuracy and detection effect, it is necessary to ensure that the position of the cube meat sample 9 on the meat sample plate I 31 or the meat sample plate II 41 is fixed and a large area of the cube meat sample 9 cannot be blocked; therefore, a plurality of limiting columns 311 are integrally arranged at the top end of the meat sample plate I 31, and the meat sample plate II 41 has the same structure as the meat sample plate I 31. The cube meat sample 9 is limited and fixed on the meat sample plate I 31 or the meat sample plate II 41 by the fitting and engagement of the plurality of limiting columns 311 with the shape of the cube meat sample 9, and at the same time, only the surface of the cube meat sample 9 is slightly blocked, so as to ensure the detection accuracy and detection effect.

[0049] Embodiment 2: The present application also discloses a detection method using the Jinhua pork quality detection device described in the above Embodiment 1, including the following steps: After the Jinhua pig is slaughtered, record the slaughter time as 9:00; Take multiple meat samples and conduct clenbuterol detection and virus detection through a clenbuterol detection device and a virus detection device respectively; During the clenbuterol detection and virus detection, take the longissimus dorsi muscle of Jinhua pigs after slaughter and make multiple cubic meat samples 9 of 3cm×3cm×3cm; Place multiple cubic meat samples 9 on multiple meat sample plates I 31 and multiple meat sample plates II 41 respectively, place the multiple meat sample plates I 31 carrying the cubic meat samples 9 on the docking mechanism 3, and place the multiple meat sample plates II 41 carrying the cubic meat samples 9 on the transfer mechanism 4; Seal the closed cover plate 16 with the box body 1, and then set the refrigeration temperature of the refrigeration device 18 to 0°C through the controller 8; Based on the slaughter time of 9:00, set the first detection time to 9:45, the second detection time to 21:00, and the third detection time to 9:00 the next day through the controller 8. Among them, the first detection time is 45 minutes after slaughter, the second detection time is 12 hours after slaughter, and the second detection time is 24 hours after slaughter; Set the first thawing time to 20:30 based on the second detection time of 21:00. The first thawing time is 0.5 to 1 hour before the second detection time. Set the second thawing time to 8:30 the next day based on the third detection time of 9:00 the next day. The second thawing time is 0.5 to 1 hour before the third detection time; Start the controller 8 to enter the working state. When the first thawing time of 20:30 or the second thawing time of 8:30 the next day is reached, the controller 8 controls the electric closed door 17 and the transfer mechanism 4 to operate. When the first detection time of 9:45, the second detection time of 21:00, or the third detection time of 9:00 the next day is reached, the controller 8 controls the conveyor 2, the docking mechanism 3, the pH value detection mechanism 5, the water holding capacity detection mechanism 6, and the disassembly mechanism 7 to operate; After the detection at the third detection time of 9:00 the next day is completed, read the detection results at multiple detection times under normal temperature conditions and the detection results at multiple detection times under refrigerated conditions through the controller 8 to obtain the meat quality detection results; If any one of the clenbuterol detection and virus detection fails, the meat quality detection result is invalid. If both the clenbuterol detection and virus detection are qualified, the meat quality detection result is valid.
