Description

Technical Field

[0001] This invention relates to the field of veterinary drug detection technology, and more specifically, to a device for detecting antibiotic residues in veterinary drugs. Background Technology

[0002] A veterinary antibiotic residue detection device is used to detect whether there are excessive antibiotic residues in animal products such as meat, dairy products, and eggs. With the advancement of medical technology, various antibiotics are commonly used in animal husbandry to treat sick livestock. However, for some livestock that have not strictly adhered to the withdrawal period, excessive antibiotic residues may remain in their bodies. Frequent consumption of such animal products may lead to antibiotic resistance in human bacteria, affecting public health. Therefore, animal products usually require quantitative or qualitative analysis and detection through chromatography, mass spectrometry, enzyme-linked immunosorbent assay (ELISA), and immunosensors.

[0003] According to a veterinary antibiotic residue detection device with publication number CN113984923A, the device includes a main body box with an internal accommodating space and a strip-shaped opening at the top. A sample holder is installed in the accommodating space and extends from the opening. The sample holder has a fixing hole in which a test tube containing the test sample is placed. A cover is installed on top of the sample holder and is hinged to the edge of the sample holder. The cover is fixed to the upper end of the sample holder by a fixing buckle. The cover has a groove corresponding to the fixing hole. When the cover is closed, the groove presses against the upper end of the test tube to prevent the test tube from shaking. A base is connected to the bottom of the sample holder. The detection device designed in this invention can cut the sample into a solution and then perform shaking, centrifugation, concentration, and other treatments. This device can quickly prepare and detect test samples, avoiding the repeated use of multiple instruments, simplifying the operation process, and greatly improving work efficiency.

[0004] Since the samples inside the container are usually of a certain height, and the rotary cutter consists of multiple sets of blades in the vertical direction, when the sample is shredded by the rotary cutter, some samples between the two sets of blades may not be effectively processed due to the relatively weak flow between the layers. At the same time, for the upper layer of samples, they are easily thrown away by centrifugal force and adhere to the inner wall of the container when shredded by the rotary cutter. Therefore, this part of the sample may also not be effectively shredded. In summary, there are still some shortcomings in the shredding process of samples when preparing test samples for chemical analysis.

[0005] Based on this, the present invention discloses a veterinary antibiotic residue detection device. Summary of the Invention

[0006] To address the issues raised in the background art regarding uneven sample shredding and the tendency of upper-layer samples to drift away from the shredding area under centrifugal force, thus hindering effective processing, this invention provides a veterinary antibiotic residue detection device. The device includes a base, an antibiotic detector mounted at the front top of the base, an L-shaped frame fixedly connected to the rear top of the base, a driving mechanism located at the rear inside the L-shaped frame, a lifting mechanism at the bottom inside the L-shaped frame, a processing chamber at the top of the lifting mechanism, a differential pressure mechanism inside the lifting mechanism, a purging mechanism at the upper part of the processing chamber, and a processing cup at the bottom of the processing chamber. The drive mechanism includes a bracket, which is slidably connected to the rear end of an L-shaped frame. A servo motor is fixedly connected to the top of the bracket. The output end of the servo motor passes through the bracket and is fixedly connected to a rotating rod. A cutter is fixedly connected to the bottom outer side of the rotating rod. An impeller is fixedly connected to the upper outer side of the rotating rod. An air inlet chamber is rotatably connected to the outer side of the impeller. Multiple air inlet holes are opened at the bottom of the air inlet chamber. An air pipe is fixedly connected to the rear end of the air inlet chamber.

[0007] In this technical solution, since the sample has a certain height before being shredded, it is necessary to actively move the entire sample back and forth in order to ensure that each layer of the sample is within the shredding area. As a further improvement to this technical solution, the lifting mechanism includes an inner cylinder, the bottom end of which is fixedly connected to the bottom end of the L-shaped frame, the rear bottom of which is fixedly connected to the bottom end of the air pipe, and a pusher is slidably connected inside the inner cylinder, the top end of which penetrates the inner cylinder and is fixedly connected to the bottom end of the processing chamber.

[0008] Based on this, in order for the airflow to exert thrust on the jacking frame, it is necessary to ensure that the jacking frame is positioned above the connection point between the inner cylinder and the air pipe. As a further improvement to this technical solution, a support ring is fixedly connected to the bottom end of the inner cylinder, and the top end of the support ring abuts against the bottom end of the pusher frame.

[0009] Based on this, in order to prevent the jacking frame from directly colliding with the top surface of the inner cylinder during rapid upward movement, it is necessary to apply a flexible barrier to the jacking frame. As a further improvement to this technical solution, a spring is fixedly connected to the top of the inner cylinder, and an annular plate is fixedly connected to the bottom of the spring. The outer side of the annular plate is slidably connected to the upper part of the inner cylinder.

[0010] In addition, to ensure the impeller's performance and enhance the stability of the support frame, it is necessary to restrict the position of the air inlet chamber and increase the contact area between the support frame and the L-shaped bracket. As a further improvement to this technical solution, a reinforcing plate is fixedly connected to the middle of the bottom end of the bracket, the rear end of the reinforcing plate is slidably connected to the rear end of the L-shaped frame, and the top end of the air intake chamber is fixedly connected to the front of the bottom end of the bracket.

[0011] In another technical solution, for samples that have adhered to the inner wall of the processing cup due to centrifugal force, they need to be removed in order to be subjected to the cutting action again. As a further improvement to this technical solution, the purging mechanism includes an exhaust chamber, the outer side of which is fixedly connected to the upper part of the processing chamber, and the bottom end of the exhaust chamber is provided with multiple through holes. The exhaust chamber is connected to the inner cylinder through an air pipe.

[0012] Based on this, in order to make the rotating rod passing through the exhaust chamber more stable, it is necessary to impose restrictions on it. As a further improvement to this technical solution, a cross plate is fixedly connected to the middle of the exhaust chamber, and the middle of the cross plate is rotatably connected to the outside of the rotating rod.

[0013] In the third option, to ensure that the airflow below the inner cylinder can be discharged quickly, it is necessary to increase the pressure difference between the upper and lower sides of the jacking frame. As a further improvement to this technical solution, the differential pressure mechanism includes connecting blocks, and multiple connecting blocks are fixedly connected to the outer side of the inner cylinder on one side. A shaped block I penetrates the upper part of each of the multiple connecting blocks, and a shaped block II abuts against one side of each of the multiple shaped blocks I. The outer sides of the multiple shaped blocks II are slidably connected to the inside of the inner cylinder.

[0014] Secondly, in order to prevent the cutter from contacting the processing chamber and the processing cup during rotation, it is necessary to limit the horizontal displacement of the processing chamber and the processing cup. As a further improvement to this technical solution, a limiting ring is provided on the outside of the processing cup, and the bottom end of the limiting ring is fixedly connected to the bottom end of the processing chamber. As a further improvement to this technical solution, an outer cylinder is slidably connected to the outside of the processing chamber, and the bottom end of the outer cylinder is fixedly connected to the bottom end of the L-shaped frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this veterinary antibiotic residue detection device, the drive mechanism and lifting mechanism enable the entire sample to be shredded using only a single cutter during the preparation of the test sample. This effectively ensures the uniformity of the shredding effect of each layer of the sample and prevents large pieces of sample from not contacting the cutter due to their low fluidity. This avoids the impact of large pieces of sample on the chemical analysis efficiency of the subsequent antibiotic detector.

[0016] 2. In this veterinary antibiotic residue detection device, the airflow below the pusher can be guided to the top of the processing cup by the set purging mechanism, thereby purging the inner wall of the processing cup to prevent the upper sample from adhering to the inner wall of the processing cup due to centrifugal force after contacting the cutter. Then, the sample is removed so that it can be processed by the cutter again.

[0017] 3. In this veterinary antibiotic residue detection device, the differential pressure mechanism can increase the air pressure difference between the upper and lower parts of the pusher frame to prevent the pusher frame from failing to drive the processing chamber and the treatment cup to reciprocate after the airflow inside the inner cylinder reaches equilibrium. At the same time, the accumulated airflow can enhance the effect of the purging mechanism. Attached Figure Description

[0020] 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.

[0021] Existing veterinary antibiotic residue detection devices have uneven sample shredding effects in the preparation of test samples, and some upper-layer samples may fly off and adhere to the inner wall of the container due to centrifugal force during the shredding process.

[0022] Therefore, the present invention provides a veterinary drug antibiotic residue detection device, see [link to related document]. Figures 1-4 As shown, it includes a base 1, an antibiotic detector 2 is provided at the front top of the base 1, an L-shaped frame 3 is fixedly connected to the rear top of the base 1, a drive mechanism 4 is provided inside the rear side of the L-shaped frame 3, a lifting mechanism 5 is provided at the bottom inside the L-shaped frame 3, a processing chamber 6 is provided at the top of the lifting mechanism 5, a differential pressure mechanism 7 is provided inside the lifting mechanism 5, a purging mechanism 8 is provided at the upper part of the processing chamber 6, and a processing cup 9 is provided at the bottom inside the processing chamber 6. The drive mechanism 4 includes a bracket 401, which is slidably connected to the rear end of the L-shaped frame 3. A servo motor 402 is fixedly connected to the top of the bracket 401. The output end of the servo motor 402 passes through the bracket 401 and is fixedly connected to a rotating rod 403. A cutter 404 is fixedly connected to the bottom outer side of the rotating rod 403. An impeller 405 is fixedly connected to the upper outer side of the rotating rod 403. An air inlet chamber 406 is rotatably connected to the outer side of the impeller 405. Multiple air inlets 407 are opened at the bottom of the air inlet chamber 406. An air pipe 408 is fixedly connected to the rear end of the air inlet chamber 406.

[0023] During operation, the L-shaped frame 3 guides and limits the support 401, ensuring that the support 401 can simultaneously drive the servo motor 402, rotating rod 403, cutter 404, impeller 405, and air inlet 406 to move. Specifically, after opening the front arc-shaped door panel of the processing chamber 6 and moving the rotating rod 403, cutter 404, and related connecting parts upwards via the support 401, the processing cup 9 containing the sample to be chopped can be placed inside the processing chamber 6. Then, the support 401 is released, and the sample slides under the influence of gravity and the surface of the L-shaped frame 3. With the slot engaged, the cutter 404 can be positioned at the upper part of the processing cup 9 and contact the upper sample. Then, the servo motor 402 is activated, so that the rotating rod 403 can simultaneously drive the cutter 404 and the impeller 405 to rotate. When the cutter 404 rotates, it can first cut the upper sample. As the impeller 405 rotates, outside air can enter the air intake chamber 406 through several evenly distributed air intake holes 407 and be discharged along a sufficiently long air pipe 408, thereby providing power for the subsequent operation of the lifting mechanism 5 and the blowing mechanism 8.

[0024] Additionally, see Figure 3 As shown, a reinforcing plate 409 is fixedly connected to the middle of the bottom end of the bracket 401. The rear end of the reinforcing plate 409 is slidably connected to the rear end of the L-shaped frame 3. The top end of the air intake chamber 406 is fixedly connected to the front of the bottom end of the bracket 401.

[0025] During operation, the reinforcing plate 409 can support the bracket 401 when it moves synchronously with the bracket 401, so as to prevent the bracket 401 from breaking due to excessive force at the connection between the bracket 401 and the L-shaped frame 3. The bracket 401 can also fix the air intake chamber 406, thereby restricting the impeller 405 and the rotating rod 403 to improve the stability of the impeller 405 and the rotating rod 403 during movement.

[0026] Further, see Figure 4 and Figure 5 As shown, the lifting mechanism 5 includes an inner cylinder 501. The bottom end of the inner cylinder 501 is fixedly connected to the bottom end of the L-shaped frame 3. The bottom rear side of the inner cylinder 501 is fixedly connected to the bottom end of the air pipe 408. A pusher 502 is slidably connected inside the inner cylinder 501. The top end of the pusher 502 passes through the inner cylinder 501 and is fixedly connected to the bottom end of the processing chamber 6.

[0027] During operation, air leaving the air inlet chamber 406 continuously enters the inner cylinder 501 through a sufficiently long air pipe 408. With the continuous rotation of the rotating rod 403 and the impeller 405, the air pressure in the lower part of the inner cylinder 501 gradually increases, pushing the pusher 502 to move the processing chamber 6 upward. At this time, the processing cup 9 inside the processing chamber 6 can move the sample upward synchronously, so that when preparing the test sample, each layer of the sample from top to bottom can be uniformly shredded by the cutter 404. This prevents the presence of un-shredded layers due to poor flowability of each layer when shredding the sample with a single or multiple blades, thus preventing large pieces of sample from affecting the chemical analysis efficiency of the subsequent antibiotic detector 2. In addition, the use of a single cutter 404, in conjunction with the movement of the processing cup 9, can ensure the shredding effect and reduce the amount of cleaning required for subsequent components.

[0028] In addition, see Figure 8 and Figure 9 As shown, a support ring 503 is fixedly connected to the bottom of the inner cylinder 501, and the top of the support ring 503 abuts against the bottom of the pusher frame 502.

[0029] During operation, the support ring 503 can lift the pusher 502 to a certain height to prevent the bottom surface of the pusher 502 from being below the connection between the air pipe 408 and the inner cylinder 501. This prevents the airflow entering the inner cylinder 501 from the air pipe 408 from failing to contact the bottom surface of the pusher 502 and thus exerting an upward thrust on the pusher 502.

[0030] Secondly, see Figure 8 As shown, a spring 504 is fixedly connected to the top end of the inner cylinder 501, and an annular plate 505 is fixedly connected to the bottom end of the spring 504. The outer side of the annular plate 505 is slidably connected to the upper part of the inner cylinder 501.

[0031] During operation, the spring 504 can push the annular plate 505 down a certain distance along the inner cylinder 501. Conversely, when the pusher 502 moves up rapidly due to the large air pressure below it, the spring 504 can absorb part of the impact force to avoid the pusher 502 directly colliding with the top of the inner cylinder 501.

[0032] Further, see Figure 5 , Figure 7 and Figure 8 As shown, the purging mechanism 8 includes an exhaust chamber 801. The outer side of the exhaust chamber 801 is fixedly connected to the upper part of the processing chamber 6. Multiple through holes 802 are opened at the bottom of the exhaust chamber 801. The exhaust chamber 801 is connected to the inner cylinder 501 through the air pipe 803.

[0033] During operation, the upper space inside the inner cylinder 501 is connected to the exhaust chamber 801 via a sufficiently long air pipe 803. When the pusher 502 is pushed upwards rapidly by the air pressure below it, the air in the upper part of the inner cylinder 501, compressed by itself and the pusher 502, can be discharged along the air pipe 803 to the exhaust chamber 801, and then discharged to the outside through the evenly distributed through holes 802. When the bottom of the pusher 502 passes the connection between the inner cylinder 501 and the air pipe 803, the cutter 404 can cut the sample in the bottom area of ​​the processing cup 9. At this time, the relatively high-pressure airflow below the pusher 502 can also be discharged through the air pipe 803 and through holes 802. 2. Simultaneously, due to the strong impact force of the airflow at this time, the airflow can be used to blow away the sample that adheres to the inner wall of the processing cup 9 after contacting the cutter 404 and being subjected to centrifugal force, so that it is placed in the upper layer area of ​​the sample inside the processing cup 9 again. As the air pressure below the pusher 502 decreases rapidly, the processing chamber 6, processing cup 9, etc. can move down under their own weight. At this time, the cutter 404 can cut the upper layer area of ​​the sample again. In summary, as the air pressure below the pusher 502 increases and decreases cyclically, the sample adhering to the inner wall of the processing cup 9 can be effectively processed by the intermittently ejected airflow along the through hole 802 and the cutter 404.

[0034] Secondly, see Figure 5 As shown, a cross plate 804 is fixedly connected to the middle of the exhaust chamber 801, and the middle of the cross plate 804 is rotatably connected to the outside of the rotating rod 403.

[0035] During operation, the cross plate 804 can limit the rotation rod 403 to prevent it from shaking or tilting when rotating.

[0036] Further, see Figure 6 As shown, the differential pressure mechanism 7 includes a connecting block 701. Multiple connecting blocks 701 are fixedly connected to the outside of the inner cylinder 501 on one side of each other. A first irregular block 702 passes through the upper part of each connecting block 701. A second irregular block 703 abuts against the side of each first irregular block 702 on one side of each other. The outside of the second irregular block 703 is slidably connected to the inside of the inner cylinder 501.

[0037] During operation, the evenly distributed connecting blocks 701 ensure that each irregularly shaped block 702 can only move up and down. Furthermore, the inclined surfaces between irregularly shaped blocks 702 and 703, along with the weight of irregularly shaped blocks 702, allow the evenly distributed irregularly shaped blocks 703 to move closer together. At this point, the irregularly shaped blocks 703 temporarily block the upward movement of the pusher frame 502 and the processing chamber 6. As air pipe 408 continues to introduce air below the pusher frame 502, when the air pressure below the pusher frame 502 can overcome the weight of the processing chamber 6, the processing cup 9, and irregularly shaped blocks 702, the pusher frame 502 can apply a thrust to the irregularly shaped blocks 703, causing them to move upward. And when the pusher frame 502 completely passes through the area where the irregularly shaped blocks 703 are located, the air pressure below the pusher frame 502 exerts a force on it. The thrust is much greater than the weight of the processing chamber 6 and the processing cup 9, so the pusher 502 can move upward quickly until the bottom of the pusher 502 passes the air inlet at the bottom of the second air pipe 803. Then, the relatively high-pressure airflow at the bottom of the pusher 502 can be quickly discharged through the second air pipe 803. In summary, the difference between the gravity and the air pressure on the pusher 502 can be increased by the first irregular block 702 and the second irregular block 703. This prevents the gravity and air pressure on the pusher 502 from reaching a balance as the pusher 502 moves upward smoothly and always stays at the connection between the second air pipe 803 and the inner cylinder 501. This further prevents the pusher 502 from failing to drive the processing chamber 6 and the processing cup 9 to move up and down normally. In addition, after the pusher 502 passes through the area where the second irregular block 703 is located, the larger air pressure below the pusher 502 at this time can also be used to enhance the blowing effect on the inner wall of the processing cup 9.

[0038] Further, see Figure 9 As shown, a limiting ring 10 is provided on the outside of the processing cup 9, and the bottom end of the limiting ring 10 is fixedly connected to the bottom end of the processing chamber 6.

[0039] During operation, the limiting ring 10 can limit the processing cup 9 to prevent it from shaking and colliding with the cutter 404 when the processing chamber 6 moves.

[0040] Further, see Figure 5 and Figure 9 As shown, an outer cylinder 11 is slidably connected to the outside of the processing chamber 6, and the bottom end of the outer cylinder 11 is fixedly connected to the bottom end of the L-shaped frame 3.

[0041] During operation, the outer cylinder 11 can restrict the movement direction of the processing chamber 6, preventing the processing chamber 6 from shaking and causing excessive shearing force at its connection with the pusher frame 502.

[0042] Working principle: In use, with the help of the limiting ring 10, the processing cup 9 containing the sample to be chopped is placed into the processing chamber 6. Then, the servo motor 402 is started, which drives the cutter 404 and impeller 405 to rotate via the rotating rod 403. In turn, outside air is continuously injected into the bottom of the inner cylinder 501 through the air pipe 408. As the air pressure at the bottom of the inner cylinder 501 continues to increase, the pusher 502 can be forced to move the processing chamber 6, the processing cup 9, and the sample smoothly upward. When the pusher 502 contacts the second irregular block 703, it can temporarily stop moving upward. As the air pressure continues to increase, when it reaches a certain value, the pusher 502 can push each of the second irregular blocks 703 away from each other and pass through the area where the second irregular block 703 is located. Then, after the resistance from the first irregular block 702 is eliminated, the pusher 502 can drive the processing chamber 6 to move upward rapidly until its bottom passes the connection between the inner cylinder 501 and the second air pipe 803. At this time, the area below the pusher 502... A relatively high-pressure airflow can enter the exhaust chamber 801 through the air pipe 803 and exit through the evenly distributed through holes 802 to purge the sample adhering to the inner wall of the processing cup 9. This prevents some of the upper sample from being thrown to the inner wall of the processing cup 9 under centrifugal force when the cutter 404 comes into contact with the upper sample, thus preventing it from being fully shredded. At the same time, as the air pressure decreases, the pusher 502 and other components can move down again to the surface of the support ring 503 to wait for the air pressure to increase again. In summary, the reciprocating up and down movement of the pusher 502 ensures that each layer of the sample in the processing cup 9 is shredded by the cutter 404. At the same time, the high-pressure airflow discharged along the through holes 802 causes a small amount of sample adhering to the surface of the processing cup 9 to fall off and be shredded again by the cutter 404. Overall, this ensures the uniformity and sufficiency of sample shredding and prevents the presence of large monomers in the prepared test sample, which would affect the chemical analysis efficiency of the antibiotic detector 2.
