Description

Technical Field

[0001] This utility model relates to the technical field of food safety testing, specifically to a rapid detection device for veterinary drug residues in food. Background Technology

[0002] Veterinary drug residue detection is widely used in the detection of veterinary drug residues in livestock and poultry meat, eggs, milk and other food and agricultural products. In livestock and poultry meat, detectable veterinary drug residues include antibiotics, anthelmintics, growth promoters, etc. Pesticide residues refer to the total amount of pesticide parent material, derivatives, metabolites, degradation products and impurities that remain in the environment, organisms and food after pesticide use.

[0003] Existing rapid detection devices for veterinary drug residues in food typically only test one sample at a time, resulting in relatively low detection efficiency. They are unsuitable for testing large batches of samples. Furthermore, staff need to retrieve the samples after testing, increasing their workload and reducing the overall efficiency of the device.

[0004] Therefore, we propose a rapid detection device for veterinary drug residues in food to address the problems mentioned above. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The interaction between components such as the rack plate, movable gear, driving bevel gear, driven bevel gear, and synchronous belt facilitates the ejection of test tubes after testing, eliminating the need for manual handling. Furthermore, the interaction between components such as the worm gear, worm wheel, T-screw, threaded sleeve, L-shaped push rod, push plate, limit telescopic rod, and vertical plate allows the rack plate to move outward as the testing probe moves downward, thus pushing the tested test tube onto the receiving platform. This improves testing efficiency, effectively reduces the workload of staff, and enhances the overall effectiveness of the device.

[0016] 2. Through the cooperation of components such as the placement tray, limiting tray, rotating cylinder, driven gear, transmission gear, fixing frame, and drive motor, the placement tray can be rotated, thereby enabling the testing of large quantities of samples. This effectively shortens the testing time and simplifies the tedious process of repeatedly picking up and placing samples. In addition, through the cooperation of components such as the arc-shaped clamping plate, moving plate, side plate, sliding rod, and return spring, the test tubes can be clamped and positioned during placement, improving their stability and preventing them from shifting and falling due to centrifugal force during rotation, resulting in better performance.

A detection probe 20 is fixedly installed at the bottom of the movable plate 8 near the front side. The pusher assembly 6 can push the tested test tube 5 to the receiving platform 3. The transmission assembly 9 can provide power for the operation of the pusher assembly 6.

[0031] Specifically, a limiting plate 41 is rotatably mounted on the bottom of the placement tray 4, and a rotating cylinder 42 is movably mounted through the middle of the limiting plate 41. The top of the rotating cylinder 42 is fixedly mounted on the placement tray 4. A driven gear 43 is fixedly sleeved on the outer side of the rotating cylinder 42 near its end. A transmission gear 44 meshes with the right side of the driven gear 43. A fixing frame 45 is fixedly mounted on the bottom of the worktable 1 near its left side. A drive motor 46 is fixedly mounted on the top of the inner side of the fixing frame 45. The output end of the drive motor 46 extends movably through to the outer side of the worktable 1 and is fixedly mounted on the transmission gear 44, which can drive the placement tray 4 to rotate, thereby enabling the detection of a large number of samples and effectively shortening the detection time.

[0032] Specifically, a support rod is fixedly installed at the bottom of the limiting plate 41 near the left side, and the lower end of the support rod is fixedly installed on the worktable 1 to support the limiting plate 41.

[0033] Specifically, arc-shaped clamps 51 are attached to the two sides of the outer side of the test tube 5 near the middle. Movable plates 52 are fixedly installed at the middle of the top of the arc-shaped clamps 51. Side plates 53 are provided on the outer side of the movable plates 52. The bottom of the side plates 53 are fixedly installed on the placement tray 4. Sliding rods 54 are slidably installed on the side plates 53. The inner ends of the sliding rods 54 are fixedly installed on the adjacent movable plates 52, which serve to clamp and position the test tube 5.

[0034] Specifically, a return spring 55 is sleeved on the outer side of the sliding rod 54, and the two ends of the return spring 55 are fixedly installed on the adjacent moving plate 52 and side plate 53, which facilitates the movement and restoration of the sliding rod 54.

[0035] In this embodiment, the transmission assembly 9 includes a rack plate 91 fixedly installed at the bottom of the movable plate 8 near the rear side and a movable gear 92 meshing with the left side of the rack plate 91 near the bottom. A rotating rod is fixedly installed through the middle of the movable gear 92. An L-shaped limiting plate is movably installed at the rear end of the rotating rod, and the front side of the L-shaped limiting plate is fixedly installed on the L-shaped plate frame 7. A driving bevel gear 93 is fixedly installed at the front end of the rotating rod. A driven bevel gear 94 meshes with the bottom of the driving bevel gear 93. A movable shaft is fixedly installed at the bottom of the driven bevel gear 94, and the lower end of the movable shaft is movably installed on the L-shaped plate frame 7. A synchronous pulley A is fixedly sleeved on the outer side of the movable shaft near the bottom end.

The synchronous belt 95 can be rotated by the up and down movement of the movable plate 8.

[0036] In this embodiment: During use, the operator can place different food samples to be tested into several test tubes 5. After placement, the tubes are inserted into the inner cavities of adjacent placement slots. Simultaneously, the insertion compresses the adjacent arc-shaped clamps 51, which in turn compress the adjacent return springs 55. The rebound force of the return springs 55, through the arc-shaped clamps 51, clamps and fixes the test tubes 5. After the test tubes 5 are placed, the hydraulic cylinder 10 is activated, causing the movable plate 8 to move downwards. As the movable plate 8 moves downwards, it causes the detection probe 20 to move downwards and extend into the test tubes 5 to detect pesticide and veterinary drug residues in the samples, and the data is uploaded. Furthermore, the downward movement of the movable plate 8 also causes the rack plate 91 to move downwards. When the device moves, it drives the movable gear 92 to rotate. The rotation of the movable gear 92 drives the active bevel gear 93 to rotate via the rotating rod. The rotation of the active bevel gear 93 drives the movable shaft to rotate via the driven bevel gear 94. The rotation of the movable shaft drives the synchronous belt 95 to rotate via the synchronous pulley A. In addition, after the detection probe 20 moves downward and completes the detection, it can be reversed to move upward and return to its original position. At this time, the movable gear 92 will also rotate in the opposite direction via the rack plate 91. Then, the drive motor 46 will run. When the drive motor 46 runs, it drives the transmission gear 44 to rotate. The rotation of the transmission gear 44 drives the rotating cylinder 42 to rotate via the driven gear 43. The rotation of the rotating cylinder 42 drives the placement tray 4 to rotate, which can rotate the next test tube 5 to the position of the previous test tube 5, thereby improving the detection efficiency.

[0037] Example 2

[0038] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 , Figure 5 , Figure 8 and Figure 10 The feeding assembly 6 includes a worm 61 located in the middle of the circular opening and a worm wheel 62 meshing with the front side of the worm 61 near its top. The lower end of the worm 61 passes through the inner cavity of the rotating cylinder 42 and is movably mounted on the top of the workbench 1. The synchronous wheel B is fixedly sleeved on the outer side of the worm 61. A limit frame is movably mounted on the outer side of the worm 61 near its top via a bearing. The bottom of the limit frame passes through the inner cavity of the rotating cylinder 42 and is fixedly mounted on the top of the workbench 1. A T-shaped screw 63 is fixedly installed through the middle of the upper part of the worm wheel 62. A support frame is movably mounted on the left end of the T-shaped screw 63. The lower end of the support frame is fixedly mounted on the limit frame. A threaded sleeve 64 is threadedly installed on the outer side of the T-shaped screw 63 near its left end. An L-shaped push rod 65 is fixedly installed in the middle of the rear side of the threaded sleeve 64. A push plate 66 is fixedly installed on the right end of the L-shaped push rod 65, which can drive the push plate 66 to move back and forth left and right to push the test tube 5 without the need for staff to pick it up.

[0039] Specifically, a limiting telescopic rod 661 is fixedly installed on the left side of the push plate 66 near the rear side, and a vertical plate 662 is fixedly installed on the left end of the limiting telescopic rod 661. The bottom of the vertical plate 662 is fixedly installed on the limiting frame, which serves to guide and limit the movement of the push plate 66.

[0040] In this embodiment: when the synchronous belt 95 rotates, it drives the worm gear 61 to rotate. When the worm gear 61 rotates, it drives the T-shaped screw 63 to rotate through the worm wheel 62. When the T-shaped screw 63 rotates, it drives the threaded sleeve 64 to move to the right. When the threaded sleeve 64 moves to the right, it drives the push plate 66 to move to the right through the L-shaped push rod 65, which pushes the tested test tube 5 onto the receiving platform 3 for easy handling by staff.

[0041] Working principle: During use, the operator can place different food samples to be tested into several test tubes 5. After placement, the tubes are inserted into the inner cavities of adjacent placement slots. Simultaneously, the insertion compresses the adjacent arc-shaped clamps 51, which in turn compress the adjacent return springs 55. The rebound force of the return springs 55, through the arc-shaped clamps 51, clamps and fixes the test tubes 5. After the test tubes 5 are placed, the hydraulic cylinder 10 operates, causing the movable plate 8 to move downwards. As the movable plate 8 moves downwards, it causes the detection probe 20 to move downwards, extending into the test tubes 5 to detect pesticide and veterinary drug residues and upload the data. Furthermore, the downward movement of the movable plate 8 also causes the rack plate 91 to move downwards, which in turn causes the movable gear 92 to rotate. The rotation of the movable gear 92, in turn, drives the driving bevel gear 93 to rotate via a rotating rod. The rotation of the driving bevel gear 93, in turn, drives the movable shaft to rotate via a driven bevel gear 94. The rotation of the movable shaft, in turn, drives the synchronous pulley... A drives the synchronous belt 95 to rotate. Additionally, after the detection probe 20 moves downwards for detection, it can be reversed to move upwards to its original position. This also drives the movable gear 92 to rotate in the opposite direction via the rack plate 91. Then, the drive motor 46 runs, driving the transmission gear 44 to rotate. The rotation of the transmission gear 44 drives the rotating cylinder 42 to rotate via the driven gear 43. The rotation of the rotating cylinder 42 then drives the placement tray 4 to rotate, thus rotating the next test tube 5 to the position of the previous test tube 5, improving efficiency. The efficiency of the test is improved. When the synchronous belt 95 rotates, it drives the worm gear 61 to rotate. When the worm gear 61 rotates, it drives the T-shaped screw 63 to rotate through the worm wheel 62. When the T-shaped screw 63 rotates, it drives the threaded sleeve 64 to move to the right. When the threaded sleeve 64 moves to the right, it drives the push plate 66 to move to the right through the L-shaped push rod 65. This pushes the tested test tube 5 onto the receiving platform 3 for easy retrieval by the staff. When the test probe 20 moves upward to return to its original position, it drives the push plate 66 to move to the left to return to its original position, which is conducive to the next push operation.

[0042] The detection probe 20 involved in this application is a publicly available prior art, so it will not be described in detail here, and its detection of food samples in multiple test tubes 5 will not affect the detection data.

[0043] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
