Description

Technical Field

[0001] This invention relates to the field of meat quality testing technology, and in particular to an intelligent sampling device for testing the quality of Uxin black beef. Background Technology

[0002] As a high-end beef cattle breed, the Uxin Black Cattle is a key breeding target in the beef cattle industry due to its high-grade marbled beef with uniform marbling. Currently, meat quality testing of Uxin Black Cattle needs to cover multiple dimensions, including genotyping, nutritional component analysis, and research on the patterns of meat quality in different parts of the cattle. The sampling process is the core prerequisite for determining the reliability of the test data. Existing sampling devices lack a precise positioning mechanism for the finely segmented parts of Uxin Black Cattle, resulting in large deviations in sampling points. Furthermore, the sampling depth and sample volume rely on manual control, leading to low standardization. This results in a lack of comparability between samples from different parts and individuals, making it difficult to support research goals such as formulating technical specifications for meat quality assessment and completing reports on the patterns of meat quality in different parts of the cattle.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: Existing meat quality testing sampling devices still have many shortcomings: impurities on the surface of beef are easily mixed into the sample, and cross-contamination is prone to occur when multiple samples are sampled, affecting the accuracy of gene detection and nutritional component analysis; the replacement of sampling tubes is cumbersome, lacks automated repositioning and sample collection functions, and has low sampling efficiency, which cannot meet the large-scale sampling needs of the core group of Uxin black cattle. The operation relies on professional technicians, and there are many manual intervention links, which not only increases labor costs, but also easily leads to sample damage or information confusion due to operational errors, which seriously restricts the efficient development of Uxin black beef quality testing and related research.

[0021] Reference Figure 1-7 As shown in this embodiment: the cleaning component 4 includes a driven rod 41 disposed on one side of the roller 3, and a spring 42 disposed on the outside of the driven rod 41. The spring 42 is connected to the cleaning cotton 43 to prevent impurities from mixing into the sample and affecting the detection accuracy.

[0022] The inner wall of the threaded shell 51 is provided with a groove 52, and four sets of grooves 52 are equally spaced. Each set of grooves 52 is provided with a connecting block 53. A rotating rod 54 is rotatably connected to one side of the connecting block 53. A spring 55 is provided between the rotating rod 54 and the connecting block 53.

[0027] A second motor 92 is installed on one side of the support plate 91. The output shaft of the second motor 92 is equipped with a lead screw 93. The lead screw 93 is threadedly connected to the moving block 94 to complete the lifting of the piston 83, thus avoiding sample leakage or contamination caused by manual operation.

[0028] Working principle: The user moves the roller 3 by grasping the handle on one side of the device body 1. The roller 3 drives the driven rod 41 on one side to rotate. A spring 42 is set on the outside of the driven rod 41, and a cleaning cotton 43 is set on one side of the spring 42. The cleaning cotton 43 cleans the impurities on the surface of the beef. The cleaning of the beef sampling area is completed simultaneously while the device is moved, so as to avoid impurities from entering the sample and affecting the accuracy of the test. In addition, the spring 42 can be adapted to beef surfaces with different flatness to ensure the consistency of the cleaning effect. The operator opens the hinged cover 2 at the top of the device body 1, and then places the sampling tubes 8 into the four sets of threaded grooves 64 evenly spaced on the surface of the turntable 63. Each threaded groove 64 has a threaded shell 51 inside, and each sampling tube 8 is inserted into the threaded shell 51. Four sets of inclined arc plates 57 are rotatably connected inside the threaded shell 51. The sampling tubes 8 are supported by the arc plates 57, which in turn drive the rotating block 56 to rotate. The rotating block 56 then drives the rotating rod 54 to rotate. The rotating rod 54 is rotatably connected to the connecting block 53. A spring 55 is provided between the rotating rod 54 and the connecting block 53 for resetting the rotating rod 54. The connecting block 53 is connected to the groove 52. The four sets of arc plates 57 fix the sampling tubes 8. Automatic clamping is achieved by the sampling tubes 8 supporting the arc plates 57, adapting to different specifications of sampling tubes 8. The spring 55 provides a resetting force to ensure clamping stability. The four sets of threaded grooves 64 can pre-load multiple sets of sampling tubes 8, reducing the time spent on frequent tube loading and improving sampling efficiency. Then, the motor 62 inside the device body 1 is activated. The motor 62 is fixed to the device body 1 via the support block 61 at the bottom. The motor 62 drives the output shaft turntable 63 to rotate one-quarter. The turntable 63 drives a set of sampling tubes 8, which are fixed inside a set of threaded grooves 64 via the fixing structure 5, to rotate to the position directly above the outlet 11. Then, the cylinder 72 inside the device body 1, which is fixed via the receiving block 71, is activated. The cylinder 72 drives the bottom receiving block 73 of the output shaft to move downward. The bottom receiving block 73 drives the housing 76 to move downward. A magnet 74 is provided on the inner side of the gear ring 79, and a magnet 75 is provided on the outer side of the threaded housing 51. The magnet 74 on the inner side of the gear ring 79 and the magnet 75 on the outer side of the threaded housing 51 are magnetically attracted and fixed, thereby driving the motor 77 inside the housing 76 to rotate forward. The motor 77 drives the gear 78 on the output shaft to rotate. The gear 78 meshes with the gear ring 79, which is slidably connected inside the housing 76. The gear ring 79 drives the magnetically fixed threaded shell 51 to rotate. The threaded shell 51 is threadedly connected to the threaded groove 64. The threaded shell 51 drives the fixed tube shell 81 to move downward. The needle 82 at the bottom of the tube shell 81 passes through the outlet 11 opened at the bottom of the device body 1, so that the needle 82 samples the beef. The camera 10 at the bottom of the device body 1 monitors the needle 82. Then, the cylinder 72 is started to drive the shell 76 to move upward. With the help of the reverse drive motor 77, the gear ring 79 drives the magnetically fixed threaded shell 51 to move upward in reverse. Thus, a set of needles 82 can sample one point of beef. The rotation angle of the turntable 63 is precisely controlled by the motor 62 to realize the rapid repositioning of the sampling tube 8. The magnetic attraction and threaded transmission ensure the stable transmission of rotational power and facilitate subsequent separation. The sampling depth is accurately controlled by the rotation stroke of the thread, avoiding inconsistent sampling depth caused by manual operation and improving the standardization of the samples. The continuous start of cylinder 72 drives the housing 76 to move upward, so that the upward force is greater than the magnetic attraction force. As a result, the first magnet 74 on the inner side of the toothed ring 79 disengages from the second magnet 75 on the outer side of the threaded shell 51. The motor 62 is then driven to rotate the turntable 63 by a quarter turn, thereby rotating a new set of sampling tubes 8 to a position directly above the outlet 11. Then, the device body 1 is pushed to the next sampling point of the beef. The magnetic attraction is automatically disengaged by the pulling force of cylinder 72, without the need for additional operation steps, thus improving tube changing efficiency. Continuous sampling at multiple sampling points can cover the meat quality testing needs of different parts of Uxin black cattle after cutting, supporting the study of the meat quality patterns of different parts. As the turntable 63 rotates, a set of sampling tubes 8 that have been sampled from beef rotates to one side of the lifting structure 9. Since the device body 1 is fixedly equipped with a frame plate 91, the motor 92 on one side of the frame plate 91 is started to rotate forward. The motor 92 drives the lead screw 93 to rotate. The lead screw 93 is threadedly connected to the outer moving block 94. The moving block 94 is slidably connected to the long rod 95. The moving block 94 drives the electric push rod 96 on one side downward to the position between the pull block 85 and the tube shell 81. Then, the electric push rod 96 drives the output shaft chuck 97 to move below the pull block 85. The chuck 97 is U-shaped and moves to the outside of the pull rod 84. Then, the motor 92 reverses and drives the lead screw 93 to rotate. 3. The screw connection with the moving block 94 moves upward. The moving block 94 drives the collet 97 of the output shaft of the electric push rod 96 to move upward. Thus, the collet 97 drives the pull rod 84 on one side of the pull block 85 to move upward. The pull rod 84 drives the piston 83 located inside the tube shell 81 to move upward. Thus, the piston 83 generates suction to adsorb the sample sampled inside the needle 82 into the cavity below the piston 83, which facilitates subsequent detection work. The piston 83 is automatically lifted by the mechanical structure, avoiding sample leakage or contamination caused by manual operation. The U-shaped collet 97 can stably fit the pull rod 84 to ensure the stability of the lifting process, so that the sample is completely retained in the tube shell 81, providing a high-quality sample without contamination for subsequent gene detection, nutrient component detection, etc.
