Description

Technical Field

[0001] The invention relates to the technical field of meat detection, in particular to a rapid sampler for meat quality traits of different parts of beef. Background Art

[0002] Traditional beef sampling methods rely on knife cutting, which is laborious for thicker cuts and difficult to sample internally, especially when large quantities of raw meat are piled high. Furthermore, the cuts are irregular in shape and may require secondary processing before testing or storage, making the process cumbersome and inefficient.

[0003] The patent with patent announcement number CN221078104U relates to the field of meat inspection technology, specifically a food inspection sampling device, including a sampling drill bit, a fixed rod fixedly connected to the top of the sampling drill bit, a support plate fixedly connected to the top of the sampling drill bit, a sampling triangular cutting blade is provided on the top of the sampling drill bit, and a pushing block located on the inner side of the sampling triangular cutting blade is provided on the top of the sampling drill bit. The above scheme first drives the support rod to drive the pushing ring to push the pushing block, and then the pushing block drives the connecting rod under the limit of the support plate to push the sampling triangular cutting blade to the outside of the sampling drill bit, and finally the pressing plate pushes the fixed rod and the sampling drill bit, so that the sampling drill bit drives the sampling triangular cutting blade to be inserted into the meat. After the sampling triangular cutting blade samples the meat, it is pressed against the elastic ring and pulled to reset, thereby having the advantage of facilitating sampling, replacing the method of rotating the handle when sampling meat in the existing technical solution, and improving the convenience of meat sampling for users.

[0004] In the above patent, the convenience of meat sampling for users is improved. However, if the sampler cannot automatically cut and mix the sample, the operator needs to manually take the sampled beef chunks out of the storage cylinder and then cut, mash or mix them with tools such as knives, further extending the processing time.

[0021] 3. Through the setting of the stabilizing device, the position of the hollow cylinder is fixed when the sleeve ring rotates to reach the sampling area. If the position of the hollow cylinder is frequently displaced, the operation time will be prolonged. After the position is fixed, the sampling can be completed in one go, which improves efficiency and is suitable for rapid sampling needs. After the position of the hollow cylinder is fixed, the limiting rod is inserted into the limiting ring by moving the limiting rod so that the moving range of the pull plate is limited to prevent the hollow cylinder from losing its fixation due to accidental external force, thereby causing deviation in the sampling area and affecting the efficiency of sampling.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 4, a rapid sampler for meat quality properties of different parts of beef, including a fixed frame 1, a hollow cylinder 2 is rotatably installed on the inner wall of the fixed frame 1, a discharge port 3 is provided on the inner wall of the hollow cylinder 2, and a sampling device 4, an auxiliary device 5 and a stabilizing device 6 are provided on the surface of the hollow cylinder 2; wherein, the sampling device 4 includes a cutting cylinder 40, a pressing seat 41, a rotating disk 42, a screw dragon 43, a round button 1 44, a scraper 45, a round button 2 46 and a stirring piece 47, the cutting cylinder 40 is slidably installed on the circumferential surface of the hollow cylinder 2, the pressing seat 41 is fixedly installed on the circumferential surface of the cutting cylinder 40, and the rotating disk 42 is rotatably installed on the circumferential surface of the cutting cylinder 40 At the top of the hollow cylinder 2, the auger 43 is set at the bottom of the rotating disk 42, the round button 1 44 is fixedly installed on the circumferential surface of the auger 43, and the scraper 45 is fixedly installed on the surface of the round button 1 44. The scraper 45 rotates to clean the beef adhering to the inner wall of the hollow cylinder 2. At the same time, the scraper 45 can also discharge the internal beef when the discharge port 3 is opened. The round button 2 46 is fixedly installed on the circumferential surface of the auger 43, and the stirring blade 47 is fixedly installed on the surface of the round button 2 46. The beef is cut and stirred by the stirring blade 47, which can ensure the uniformity of the sample and reduce subsequent secondary processing operations.

[0033] The circumferential surface of the hollow cylinder 2 is provided with a handle, the bottom of the cutting cylinder 40 is provided with a blade, the number of stirring blades 47 is set to two, and they are symmetrical with each other along the vertical center axis of the round button 44. The beef is cut by rotating the cutting cylinder 40.

[0034] The auger 43 contacts the inner wall of the hollow cylinder 2 , and the scraper 45 contacts the inner wall of the hollow cylinder 2 . There are two scrapers 45 , which are symmetrical to each other along the vertical center axis of the rotating disk 42 .

[0035] By aligning the cutting cylinder 40 with the sampling point of the beef, the pressing seat 41 is pressed downward to insert the cutting cylinder 40 into the beef, and then the pressing seat 41 is rotated left and right to allow the blade to cut the beef. The beef is then squeezed into the interior of the cutting cylinder 40, and then the rotating disk 42 is rotated. The rotation of the rotating disk 42 drives the auger 43 to rotate, and the rotation of the auger 43 causes the beef to be transported to the deep part of the hollow cylinder 2 for storage. When the auger 43 rotates, it drives the round button 44 to rotate. The rotation of the round button 44 drives the scraper 45 to rotate. The scraper 45 rotates to clean the beef adhering to the inner wall of the hollow cylinder 2, and the scraper 45 can also be used to clean the inner wall of the hollow cylinder 2 when the discharge port 3 is opened. When manually taking samples, the operator's hands and tools may touch the sample surface, thereby introducing bacteria, dust and other pollutants. In this way, the operator is prevented from contaminating the beef sample. When the auger 43 rotates, the round button 46 will be driven to rotate, and the rotation of the round button 46 will drive the stirring blade 47 to rotate. The stirring blade 47 cuts and stirs the beef, which can ensure the uniformity of the sample and reduce subsequent secondary processing operations. If the sampler cannot automatically cut and mix the sample, the operator needs to manually take the sampled beef block out of the storage tube, and then use tools such as knives to cut, mash or mix it. This process is time-consuming and labor-intensive, especially in batch sampling, which will significantly reduce the detection efficiency.

[0036] Reference Figures 1-8 , an auxiliary device 5 and a stabilizing device 6 are provided on the surface of the hollow cylinder 2.

[0037] The auxiliary device 5 includes a sampling ring 50, a support rod 51 and a sleeve ring 52. The sampling ring 50 is fixedly installed at the bottom of the fixing frame 1, the support rod 51 is fixedly installed at the bottom of the sampling ring 50, and the sleeve ring 52 is fixedly installed on the circumferential surface of the hollow cylinder 2 to prevent the sampling position from being offset due to hand force or the slippery surface of the beef, ensuring that samples from the designated part are collected.

[0038] A number of spikes are provided at the bottom of the support rod 51, and a card slot is provided on the surface of the sleeve ring 52 close to the fixing frame 1. The limit block 62 is inserted into the card slot by resetting through the No. 1 spring 63. At this time, the position of the hollow tube 2 is fixed. If the position of the hollow tube 2 is frequently shifted, the operation time will be prolonged. After the position is fixed, the sampling can be completed at one time, which improves efficiency and is suitable for fast sampling needs.

[0039] The auxiliary device 5 also includes an elastic telescopic rod 53 and a contact plate 54. The fixed end of the elastic telescopic rod 53 is fixedly mounted on the surface of the hollow cylinder 2, and the contact plate 54 is fixedly mounted on the movable end of the elastic telescopic rod 53. The number of the elastic telescopic rods 53 and the contact plates 54 is set to four, and they are arrayed along the center circumference of the hollow cylinder 2 to buffer the movement of the cutting cylinder 40 and prevent the blade of the cutting cylinder 40 from deformation or damage.

[0040] The stabilizing device 6 includes a slide rod 60 and a limit block 62. The slide rod 60 is slidably mounted on the inner wall of the fixing frame 1. The limit block 62 is fixedly mounted on the left side of the slide rod 60. The front side of the limit block 62 is set as an inclined surface. The number of the slide rod 60 and the limit block 62 is set to two, and they are symmetrical to each other along the vertical center axis of the hollow cylinder 2. The outer wall of the sleeve 52 will contact the inclined surface of the limit block 62, thereby causing the limit block 62 to move outward.

[0041] The stabilizing device 6 also includes a limit plate 61 and a No. 1 spring 63. The limit plate 61 is fixedly installed on the circumferential surface of the slide rod 60, and the No. 1 spring 63 is arranged between the limit plate 61 and the fixed frame 1. The limit plate 61 is driven to reset by the set No. 1 spring 63. The number of limit plates 61 and No. 1 spring 63 is set to two, and they are symmetrical to each other along the vertical center axis of the hollow cylinder 2. The movement of the limit block 62 drives the limit plate 61 and the slide rod 60 to move simultaneously, and the movement of the limit plate 61 will compress the No. 1 spring 63.

[0042] The stabilizing device 6 also includes a pull plate 64, a connecting plate 65 and a limiting rod 66. The pull plate 64 is fixedly installed on the right side of the slide rod 60, the connecting plate 65 is fixedly installed on the front side of the fixing frame 1, and the limiting rod 66 is slidably installed on the inner wall of the connecting plate 65. The number of the pull plate 64, the connecting plate 65 and the limiting rod 66 is set to two, and they are symmetrical to each other along the vertical center axis of the hollow tube 2 to prevent the hollow tube 2 from losing its fixation due to accidental external force, thereby causing deviation in the sampling area and affecting the efficiency of sampling.

[0043] A limiting ring is provided on one side of the pull plate 64 close to the limiting rod 66. After the position of the hollow cylinder 2 is fixed, the limiting rod 66 is moved and inserted into the limiting ring so that the limiting rod 66 limits the moving range of the pull plate 64. A No. 2 spring is provided between the limiting rod 66 and the connecting plate 65. The number of the limiting ring and the No. 2 spring is set to two, and they are symmetrical to each other along the vertical center axis of the hollow cylinder 2. The limiting rod 66 is reset by the provided No. 2 spring.

[0044] When the cutting cylinder 40 moves downward, it contacts the contact plate 54, causing the contact plate 54 to move downward and compress the movable end of the elastic telescopic rod 53, and the movement of the cutting cylinder 40 is buffered by the elastic telescopic rod 53 to prevent the blade of the cutting cylinder 40 from being deformed or damaged, thereby affecting subsequent sampling. When placing the sampler, the sampler is temporarily fixed by inserting the spike part of the support rod 51 into the beef sampling area, and then the hollow cylinder 2 is rotated to the sampling area, that is, the movement of the hollow cylinder 2 drives the sleeve ring 52 to move. The beef has a soft texture and may have texture differences. After the spike is inserted, the sampler can be firmly fixed in the target position to prevent the sampling position from being offset due to hand force or the slippery surface of the beef, ensuring that the sample at the designated part is collected. When the sleeve ring 52 rotates to reach the sampling area, the sleeve ring The outer wall of the connecting ring 52 will contact the inclined surface of the limit block 62, so that the limit block 62 moves outward. The movement of the limit block 62 drives the limit plate 61 and the slide rod 60 to move at the same time. The movement of the limit plate 61 will compress the No. 1 spring 63. When the slot of the connecting ring 52 overlaps with the limit block 62, the No. 1 spring 63 is reset to allow the limit block 62 to be inserted into the slot. At this time, the position of the hollow cylinder 2 is fixed. If the position of the hollow cylinder 2 is frequently shifted, the operation time will be extended. After the position is fixed, the sampling can be completed at one time, which improves efficiency and is suitable for fast sampling needs. After the position of the hollow cylinder 2 is fixed, the limiting rod 66 is inserted into the limiting ring by moving, so that the limiting rod 66 limits the moving range of the pull plate 64 to prevent the hollow cylinder 2 from losing its fixation due to accidental external force, thereby causing deviation in the sampling area and affecting the sampling efficiency.
