[0002] Sampling and testing of beef balls is a crucial step in ensuring food safety and product compliance, involving multi-dimensional testing of microbial safety, ingredient authenticity, and physicochemical indicators.

[0003] Chinese patent CN113720787B discloses a sampling and testing device for food safety, including a spectral detection module for collecting, analyzing, and detecting the surface spectrum of food, a storage tank for storing the food to be tested, a discharge side pipe for temporarily placing randomly sampled food with a through hole on the left side of the storage tank, a lifting column with a through hole for upper and lower limit sliding connection, a inclined block fixedly connected inside the storage tank, a lower part of the inclined block near the discharge side pipe, and the surface of the lifting column penetrating the inclined block and slidingly connected to the inclined block for upper and lower limit sliding connection.

[0004] In the aforementioned patents and prior art, sampling inspection of beef balls is usually carried out on the finished product. Furthermore, traditional inspection methods typically involve inspecting the beef balls as a whole or cutting them open and crushing them for inspection, which can lead to certain errors during the inspection process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sampling device and a sampling method for detecting beef balls.

[0006] A sampling device includes a support frame, a beef ball moving trough mounted on the top of the support frame, a dividing support platform mounted on the top of the beef ball moving trough, a random sampling mechanism mounted inside the beef ball moving trough, a squeezing and dividing mechanism mounted on the top of the dividing support platform, and a sample storage mechanism mounted on the top of the dividing support platform.

[0007] The random sampling mechanism is slidably installed inside the beef ball moving trough, and the top of the random sampling mechanism can pass through the dividing support platform and engage with the extrusion dividing mechanism.

[0008] The beef ball moving trough can be connected to the external inlet and outlet. The random sampling mechanism can randomly select beef balls passing through the beef ball moving trough. The random sampling mechanism can move the randomly selected beef balls to the top of the dividing support platform. The extrusion dividing mechanism can extrude and divide the beef balls on the random sampling mechanism into slices. When the extrusion dividing mechanism moves, it can move the beef balls inside to the sample storage mechanism. The sample storage mechanism can store the beef balls after they have been divided into slices.

[0009] Preferably, the random sampling mechanism includes a beef ball guide plate, which is fixedly installed inside the beef ball moving trough. A beef ball diversion plate is installed outside the beef ball guide plate, a beef ball lifting plate is installed inside the beef ball diversion plate, a transmission limiting frame is installed inside the beef ball lifting plate, a beef ball passage hole is opened inside the beef ball lifting plate, and a lifting telescopic rod is connected to the bottom of the transmission limiting frame.

[0010] Preferably, the top of the beef ball guide plate is an inclined slope, and the higher side of the beef ball guide plate contacts and is flush with the beef ball lifting plate. The beef ball guide plate and the beef ball diverting plate divide the movement trajectory of the beef balls inside the dividing support platform into two parts.

[0011] The beef ball guide plate and the beef ball diversion plate can guide the beef balls into the beef ball lifting plate, and the beef balls inside the beef ball lifting plate can pass through the beef ball passage hole opened inside the beef ball lifting plate.

[0012] Preferably, the bottom of the transmission limiting frame is slidably installed inside the beef ball lifting plate, the fixed end of the lifting telescopic rod is fixedly connected to the inside of the beef ball moving groove, the movable end of the lifting telescopic rod is fixedly connected to the transmission limiting frame, and the top of the transmission limiting frame passes through the dividing support platform and can be engaged with the extrusion dividing mechanism.

[0013] When the lifting telescopic rod extends or retracts, it can drive the transmission limiting frame to move up and down. When the transmission limiting frame moves up and down, the bottom of the random sampling mechanism can move to the middle of the beef ball lifting plate. When the transmission limiting frame rises, the bottom of the transmission limiting frame can separate the beef ball passage hole to prevent the beef ball from passing through. When the transmission limiting frame continues to rise, it can drive the beef ball lifting plate to move upward synchronously. When the beef ball lifting plate moves upward, it can drive the beef ball to move above the dividing support platform.

[0014] Preferably, the extrusion and segmentation mechanism includes a horizontal telescopic rod, which is fixedly installed on the top of the segmentation support platform. The movable end of the horizontal telescopic rod is connected to an extrusion transmission connecting plate. A connecting plate moving slide rail is installed on the top of the segmentation support platform. A sleeve connecting plate is slidably installed on the top of the connecting plate moving slide rail. Both ends of the sleeve connecting plate are connected to transmission mounting cylinders. A beef ball segmentation mechanism is installed inside the transmission mounting cylinder.

[0015] Preferably, the transmission mounting cylinder is installed on the top of the dividing support platform through a sliding connection between the sleeve connecting plate and the connecting plate sliding rail. The beef ball dividing mechanism is connected to the movable end of the horizontal telescopic rod through the extrusion transmission connecting plate. The outside of the transmission mounting cylinder can be engaged with the top of the transmission limiting frame.

[0016] When the horizontal telescopic rod extends or retracts, it can drive the beef ball dividing mechanism to move through the compression transmission connecting plate. When the beef ball dividing mechanism moves, it can drive the sleeve connecting plate to slide on the top of the connecting plate moving slide rail through the transmission mounting cylinder. When the sleeve connecting plate moves on the top of the connecting plate moving slide rail, it can drive the transmission mounting cylinder to engage with the top of the transmission limiting frame. The transmission limiting frame can limit the movement range of the transmission mounting cylinder.

[0017] Preferably, the beef ball cutting mechanism includes an outer connecting plate, a middle connecting plate, and an inner mounting plate. The extrusion transmission connecting plate passes through the side wall of the transmission mounting cylinder and is connected to the outside of the outer connecting plate. The inner mounting plate is slidably mounted on the inner side wall of the transmission mounting cylinder. The outer connecting plate and the inner mounting plate are slidably connected by a plurality of the middle connecting plates.

[0018] When the external connecting plate, the middle connecting plate, and the internal mounting plate move, they can all divide the beef balls into pieces. When the horizontal telescopic rod drives the external connecting plate to move through the extrusion transmission connecting plate, it can unfold the external connecting plate, the middle connecting plate, and the internal mounting plate. When the external connecting plate, the middle connecting plate, and the internal mounting plate unfold, they can move the beef balls divided into pieces inside to the sample storage mechanism.

[0019] Preferably, the sample storage mechanism includes a fixed storage rack placed on top of the dividing support platform. A fixed rack cover is installed inside the fixed storage rack. A sliding mounting column is fixedly installed inside the fixed storage rack. A movable storage rack is slidably installed outside the sliding mounting column. A movable rack cover is installed inside the movable storage rack. A fixed rack connecting plate, a storage connecting plate, and a movable rack connecting plate are slidably installed outside the movable storage rack.

[0020] Preferably, the fixed frame connecting plate is fixedly connected to the fixed storage frame, the movable frame connecting plate is fixedly connected to the movable storage frame, the movable frame connecting plate and the fixed frame connecting plate are slidably connected through a plurality of storage connecting plates, and the storage connecting plates are slidably connected to each other;

[0021] When the movable storage rack moves, it can cause the fixed rack connecting plate, the storage connecting plate and the movable rack connecting plate to unfold. When the fixed rack connecting plate, the storage connecting plate and the movable rack connecting plate unfold, they can collect the sliced ​​beef balls on the beef ball cutting mechanism. When the movable storage rack moves towards the fixed storage rack, it can cause the movable rack cover plate to splice with the fixed rack cover plate. When the movable rack cover plate splices with the fixed rack cover plate, it can seal the top of the fixed storage rack and the movable storage rack.

[0022] A sampling method for detecting beef balls uses the aforementioned sampling device.

[0023] Compared with the prior art, the present invention provides a sampling device and a sampling method for detecting beef balls, which has the following beneficial effects:

[0024] 1. In operation, this sampling device extends a horizontal telescopic rod, which drives a beef ball segmenting mechanism to move via a transmission connecting plate. As the beef ball segmenting mechanism moves, it drives a transmission mounting cylinder and a sleeve connecting plate to move along the outside of the connecting plate's sliding rail. During this movement, the beef ball segmenting mechanism compresses the beef balls on the beef ball lifting plate, segmenting them into pieces. When the horizontal telescopic rod drives the outer connecting plate via the transmission connecting plate, it unfolds the outer connecting plate, the middle connecting plate, and the inner mounting plate. This unfolding unfolds the segmented beef balls and moves them to the sample storage mechanism, allowing for subsequent testing of the beef ball's internal structure.

[0025] 2. This sampling device, when the movable storage rack moves towards the fixed storage rack, can drive the movable rack cover plate to assemble with the fixed rack cover plate. When the movable rack cover plate is assembled with the fixed rack cover plate, it can seal the top of both the fixed and movable storage racks. After the sample storage mechanism stores the beef balls, it can be removed from the dividing support platform for subsequent testing. During the storage process, the sample storage mechanism preserves the position and state of the beef balls, preventing damage to the internal beef balls during movement and thus avoiding deviations in the test results.

[0026] 3. This sampling device can control whether beef can pass through the inside of the beef ball passage hole by adjusting the height of the transmission limit frame through the lifting telescopic rod during operation. When necessary, the transmission limit frame can be moved upward to randomly extract the beef balls, which can effectively ensure the randomness of the beef ball extraction.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a sampling device and a sampling method for detecting beef balls.

[0042] Example 1

[0043] Please see Figure 1 - Figure 12 A sampling device includes a support frame 1, a beef ball moving trough 2 installed on the top of the support frame 1, a dividing support platform 3 installed on the top of the beef ball moving trough 2, a random sampling mechanism 4 installed inside the beef ball moving trough 2, a squeezing dividing mechanism 5 installed on the top of the dividing support platform 3, and a sample storage mechanism 6 installed on the top of the dividing support platform 3.

[0044] The random sampling mechanism 4 is slidably installed inside the beef ball moving tank 2, and the top of the random sampling mechanism 4 can pass through the dividing support platform 3 and engage with the extrusion dividing mechanism 5.

[0045] The beef ball moving trough 2 can be connected to the external inlet and outlet. The random sampling mechanism 4 can randomly select beef balls passing through the inside of the beef ball moving trough 2. The random sampling mechanism 4 can move the randomly selected beef balls to the top of the dividing support platform 3. The extrusion dividing mechanism 5 can extrude and divide the beef balls on the random sampling mechanism 4 into slices. When the extrusion dividing mechanism 5 moves, it can move the beef balls inside to the sample storage mechanism 6. The sample storage mechanism 6 can store the beef balls after they have been divided into slices.

[0046] During operation, the beef ball moving trough 2 can be connected to the external inlet and outlet. After the beef ball moving trough 2 is connected to the external inlet and outlet, the beef balls can pass through the inside of the beef ball moving trough 2. When the beef balls pass through the inside of the beef ball moving trough 2, the random sampling mechanism 4 can divert the beef balls and randomly extract the beef balls that have passed through the inside and drive the beef balls to rise and move to the top of the dividing support platform 3. When the extrusion dividing mechanism 5 moves at the top of the dividing support platform 3, it can extrude and divide the beef balls on the random sampling mechanism 4 into pieces. After the beef balls are divided into pieces, the extrusion dividing mechanism 5 continues to move and can drive the divided beef balls into pieces to the inside of the sample storage mechanism 6. After the beef balls are moved into the inside of the sample storage mechanism 6, the sample storage mechanism 6 can fix and store the divided beef balls. During the operation, the extrusion dividing mechanism 5 can divide the beef into pieces, and the sample storage mechanism 6 can fix and store the divided beef balls, so that the composition of each layer and position of the beef balls can be detected during the test.

[0047] Example 2

[0048] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The random sampling mechanism 4 includes a beef ball guide plate 41, which is fixedly installed inside the beef ball moving trough 2. A beef ball diversion plate 42 is installed on the outside of the beef ball guide plate 41. A beef ball lifting plate 43 is installed inside the beef ball diversion plate 42. A transmission limit frame 44 is installed inside the beef ball lifting plate 43. A beef ball passage hole 45 is opened inside the beef ball lifting plate 43. A lifting telescopic rod 46 is connected to the bottom of the transmission limit frame 44.

[0049] The top of the beef ball guide plate 41 is an inclined slope. The higher side of the beef ball guide plate 41 contacts the beef ball lifting plate 43 and is flush with the beef ball lifting plate 43. The beef ball guide plate 41 and the beef ball diverting plate 42 divide the movement trajectory of the beef balls inside the dividing support platform 3 into two parts.

[0050] The beef ball guide plate 41 and the beef ball diverter plate 42 can guide the beef balls into the beef ball lifting plate 43. The beef balls inside the beef ball lifting plate 43 can pass through the beef ball passage hole 45 opened inside the beef ball lifting plate 43.

[0051] The bottom of the transmission limit frame 44 is slidably installed inside the beef ball lifting plate 43. The fixed end of the lifting telescopic rod 46 is fixedly connected to the inside of the beef ball moving groove 2. The movable end of the lifting telescopic rod 46 is fixedly connected to the transmission limit frame 44. The top of the transmission limit frame 44 passes through the dividing support table 3 and can be engaged with the extrusion dividing mechanism 5.

[0052] When the lifting telescopic rod 46 extends or retracts, it can drive the transmission limit frame 44 to move up and down. When the transmission limit frame 44 moves up and down, the bottom of the random sampling mechanism 4 can move to the middle of the beef ball lifting plate 43. When the transmission limit frame 44 rises, the bottom of the transmission limit frame 44 can separate the beef ball passage hole 45 to prevent the beef ball from passing through. When the transmission limit frame 44 continues to rise, it can drive the beef ball lifting plate 43 to move upward synchronously. When the beef ball lifting plate 43 moves upward, it can drive the beef ball to move above the dividing support platform 3.

[0053] During operation, the beef ball guide plate 41 guides the beef into the beef ball lifting plate 43. While the guide plate 41 guides the beef balls, the diverter plate 42 diverts the flow of beef balls. After entering the lifting plate 43, the beef balls pass through the passage hole 45. When sampling is required, the lifting telescopic rod 46 moves the transmission limit frame 44 upward. As the transmission limit frame 44 moves upward, its bottom slides inside the lifting plate 43 and moves to the center of the passage hole 45. By separating the center of the passage hole 45 with the bottom of the transmission limit frame 44, the beef balls are prevented from continuing to pass through the passage hole 45. When the lifting telescopic rod 46 continues to extend, it can drive the beef ball lifting plate 43 to move upward through the transmission limit frame 44. When the beef ball lifting plate 43 moves upward, it can move the beef ball to the top of the dividing support platform 3. After the beef ball moves to the top of the dividing support platform 3, the extrusion dividing mechanism 5 can extrude the beef ball to divide it into pieces. Then, the lifting telescopic rod 46 shortens, driving the transmission limit frame 44 and the beef ball passage hole 45 to move downward, so that the bottom of the transmission limit frame 44 and the beef ball passage hole 45 are in contact with the inside of the beef ball moving groove 2. The height of the transmission limit frame 44 can be adjusted by the lifting telescopic rod 46 to control whether the beef can pass through the inside of the beef ball passage hole 45. When necessary, the transmission limit frame 44 can be moved upward to randomly extract the beef balls, which can effectively ensure the randomness of extracting the beef balls.

[0054] Example 3

[0055] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The extrusion and division mechanism 5 includes a horizontal telescopic rod 51, which is fixedly installed on the top of the division support platform 3. The movable end of the horizontal telescopic rod 51 is connected to an extrusion transmission connecting plate 52. A connecting plate moving slide rail 55 is installed on the top of the division support platform 3. A sleeve connecting plate 54 is slidably installed on the top of the connecting plate moving slide rail 55. Both ends of the sleeve connecting plate 54 are connected to transmission mounting cylinders 53. A beef ball division mechanism 56 is installed inside the transmission mounting cylinder 53.

[0056] The transmission mounting cylinder 53 is installed on the top of the dividing support platform 3 through the sliding connection between the sleeve connecting plate 54 and the connecting plate moving slide rail 55. The beef ball dividing mechanism 56 is connected to the movable end of the horizontal telescopic rod 51 through the extrusion transmission connecting plate 52. The outside of the transmission mounting cylinder 53 can be engaged with the top of the transmission limiting frame 44.

[0057] When the horizontal telescopic rod 51 extends or retracts, it can drive the beef ball dividing mechanism 56 to move through the compression transmission connecting plate 52. When the beef ball dividing mechanism 56 moves, it can drive the sleeve connecting plate 54 to slide on the top of the connecting plate moving slide rail 55 through the transmission mounting cylinder 53. When the sleeve connecting plate 54 moves on the top of the connecting plate moving slide rail 55, it can drive the transmission mounting cylinder 53 to engage with the top of the transmission limiting frame 44. The transmission limiting frame 44 can limit the movement range of the transmission mounting cylinder 53.

[0058] The beef ball splitting mechanism 56 includes an outer connecting plate 561, a middle connecting plate 562, and an inner mounting plate 563. The extrusion transmission connecting plate 52 passes through the side wall of the transmission mounting cylinder 53 and is connected to the outside of the outer connecting plate 561. The inner mounting plate 563 is slidably mounted on the inner side wall of the transmission mounting cylinder 53. The outer connecting plate 561 and the inner mounting plate 563 are slidably connected by multiple middle connecting plates 562.

[0059] When the outer connecting plate 561, the middle connecting plate 562, and the inner mounting plate 563 move, they can all divide the beef balls into pieces. When the horizontal telescopic rod 51 drives the outer connecting plate 561 to move through the extrusion transmission connecting plate 52, it can unfold the outer connecting plate 561, the middle connecting plate 562, and the inner mounting plate 563. When the outer connecting plate 561, the middle connecting plate 562, and the inner mounting plate 563 unfold, they can move the beef balls divided into pieces inside to the sample storage mechanism 6.

[0060] During operation, the horizontal telescopic rod 51 extends, which can drive the beef ball dividing mechanism 56 to move through the compression transmission connecting plate 52. When the beef ball dividing mechanism 56 moves, it can drive the transmission mounting cylinder 53 and the sleeve connecting plate 54 to move along the outside of the connecting plate moving slide rail 55. When the transmission mounting cylinder 53 and the beef ball dividing mechanism 56 move, the beef ball dividing mechanism 56 can compress the beef balls on the beef ball lifting plate 43 to divide them into pieces. Then, when the horizontal telescopic rod 51 continues to extend, the outside of the transmission mounting cylinder 53 is locked with the top of the transmission limit frame 44, and the transmission mounting cylinder 53 cannot move further. At this time, the extension of the horizontal telescopic rod 51 continues to drive the external connecting plate 561 to move through the compression transmission connecting plate 52. When rod 51 moves the outer connecting plate 561 via the extrusion transmission connecting plate 52, it can unfold the outer connecting plate 561, the middle connecting plate 562, and the inner mounting plate 563. When the outer connecting plate 561, the middle connecting plate 562, and the inner mounting plate 563 are unfolded, the sliced ​​beef balls inside can be moved to the sample storage mechanism 6. When the horizontal telescopic rod 51 retracts, it can retract the outer connecting plate 561, the middle connecting plate 562, and the inner mounting plate 563 into the transmission mounting cylinder 53. After the random sampling mechanism 4 has sampled the beef balls, the beef ball cutting mechanism 56 extrudes the beef balls to cut them into slices, so that the specific internal structure of the beef balls can be detected in subsequent tests.

[0061] Example 4

[0062] The difference from the above embodiments is that, please refer to [link / reference needed]. Figure 1 - Figure 12 The sample storage mechanism 6 includes a fixed storage rack 61, which is placed on top of the dividing support platform 3. A fixed rack cover plate 62 is installed inside the fixed storage rack 61. A sliding mounting column 63 is fixedly installed inside the fixed storage rack 61. A movable storage rack 64 is slidably installed outside the sliding mounting column 63. A movable rack cover plate 65 is installed inside the movable storage rack 64. A fixed rack connecting plate 66, a storage connecting plate 67, and a movable rack connecting plate 68 are slidably installed outside the movable storage rack 64.

[0063] The fixed frame connecting plate 66 is fixedly connected to the fixed storage frame 61, the movable frame connecting plate 68 is fixedly connected to the movable storage frame 64, the movable frame connecting plate 68 and the fixed frame connecting plate 66 are slidably connected through multiple storage connecting plates 67, and the storage connecting plates 67 are slidably connected to each other.

[0064] When the movable storage rack 64 moves, it can cause the fixed rack connecting plate 66, the storage connecting plate 67 and the movable rack connecting plate 68 to unfold. When the fixed rack connecting plate 66, the storage connecting plate 67 and the movable rack connecting plate 68 unfold, they can collect the sliced ​​beef balls on the beef ball dividing mechanism 56. When the movable storage rack 64 moves towards the fixed storage rack 61, it can cause the movable rack cover plate 65 to splice with the fixed rack cover plate 62. When the movable rack cover plate 65 splices with the fixed rack cover plate 62, it can seal the top of the fixed storage rack 61 and the movable storage rack 64.

[0065] When the horizontal telescopic rod 51 moves the beef ball dividing mechanism 56, it can place the sliced ​​beef balls inside onto the fixed frame connecting plate 66, the storage connecting plate 67, and the movable frame connecting plate 68 in one go. After the sliced ​​beef balls are placed onto the fixed frame connecting plate 66, the storage connecting plate 67, and the movable frame connecting plate 68, the beef ball dividing mechanism 56 retracts, moving the movable storage rack 64 towards the fixed storage rack 61. When the movable storage rack 64 moves towards the fixed storage rack 61, it can also drive the storage connecting plate 67 and the movable frame connecting plate 68 towards the fixed storage rack 61. When the movable storage rack 64 moves toward the fixed storage rack 61, it can drive the movable rack cover plate 65 to splice with the fixed rack cover plate 62. When the movable rack cover plate 65 splices with the fixed rack cover plate 62, it can seal the top of the fixed storage rack 61 and the movable storage rack 64. After the sample storage mechanism 6 stores the sliced ​​beef balls, it can be removed from the dividing support table 3 for subsequent testing. During the storage process, the sample storage mechanism 6 preserves the position and state of the beef balls to prevent damage to the internal beef balls during the movement of the sample storage mechanism 6, which would lead to deviations in the test results.

[0066] Example 5

[0067] A positioning method for machining a brake assembly, using a sampling device as described in Examples 1 to 4, includes the following steps:

[0068] During operation, the beef ball moving trough 2 is first connected to the external inlet and outlet.

[0069] Then, the random sampling mechanism 4 can randomly extract the beef balls that have passed through the interior and move the beef balls up to the top of the dividing support platform 3.

[0070] When the extrusion and segmentation mechanism 5 moves on top of the segmentation support platform 3, it can extrude and segment the beef balls on the random sampling mechanism 4 into slices.

[0071] After the beef balls are sliced, the extrusion and segmentation mechanism 5 continues to move, which can move the sliced ​​beef balls into the sample storage mechanism 6.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
