Abstract
Description
Technical Field
[0001] This utility model relates to the field of food testing technology, and in particular to a device for detecting antibiotic residues in livestock and poultry meat. Background Technology
[0002] Currently, most commercially available antibiotic residue testing equipment for livestock and poultry meat integrates sample processing and testing functions, aiming to achieve rapid and automated testing. However, in the sample processing mixing stage, existing equipment generally adopts the method of adding minced meat and extractant simultaneously. Due to the instantaneous large-scale mixing of minced meat and extractant, the two are difficult to fully contact in a short period of time, resulting in some minced meat failing to effectively combine with the extractant, leading to low extraction efficiency. At the same time, the concentrated addition of materials can easily cause excessive local concentration differences in the mixed system, requiring more time and energy to achieve uniform mixing during the stirring process. This not only reduces the overall testing efficiency but may also lead to deviations in the test results due to uneven mixing, failing to accurately reflect the antibiotic residue level in livestock and poultry meat. Utility Model Content
[0003] The purpose of this invention is to solve the problems in the prior art by proposing a device for detecting antibiotic residues in livestock and poultry meat.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An antibiotic residue detection device for livestock and poultry meat includes a detection chamber, which is divided into a detection area and a mixing area by a partition. The partition has an opening. A detection component is installed in the detection area, and a stirring component and a feeding component are installed in the mixing area. The stirring component includes a mixing chamber fixed inside the detection chamber, with a top cover on top of the mixing chamber. An electric push rod for raising and lowering the top cover is installed on the top of the detection chamber. The feeding component includes an extractant hopper fixed to the top of the top cover, with a liquid outlet pipe connected to the bottom of the extractant hopper. A meat scrap hopper is fixed to the top of the top cover, with a meat outlet pipe connected to the bottom of the meat scrap hopper. A sealing block slides inside the liquid outlet pipe, and a sealing plate is provided below the meat outlet pipe. The sealing plate has a meat leakage hole with a diameter larger than the diameter of the meat outlet pipe.
[0006] Preferably, the stirring assembly further includes a stirring rod rotatably connected to the top cover via a bearing, and a motor for driving the stirring rod to rotate is mounted on the top of the top cover.
[0007] Preferably, the feeding assembly further includes a sector gear fixed to the outer surface of the stirring rod, the outer surface of the sector gear meshing with a gear housing, the sealing block being fixed to the gear housing via a connecting rod, and the sealing plate being fixed to the gear housing.
[0008] Preferably, a limiting strip is fixed to the bottom of the top cover, and a limiting block is fixed to the gear housing, with the limiting block sliding on the outer surface of the limiting strip.
[0009] Preferably, the top of the top cover is provided with an impact assembly for vibrating the meat hopper. The impact assembly includes a cylinder fixed to the top of the top cover, an impact plate fixed to one end of the cylinder extension rod, and a rubber pad fixed on the impact plate.
[0010] Preferably, the detection assembly includes a mounting plate disposed in the detection area, an immunosensor mounted on the bottom of the mounting plate, an electric push rod mounted on the detection box for driving the mounting plate to rise and fall, an extraction box disposed below the mixing box, and an electric push rod mounted on the outer surface of the detection box for driving the extraction box to move below the immunosensor.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. By designing the feeding assembly, the rotating stirring rod drives the sector gear to rotate, which in turn causes the gear housing to move the sealing block and sealing plate. This enables the orderly addition of extractant and minced meat. The extractant or minced meat is added first, followed by the other material entering the mixing chamber. This avoids the problem of excessive local concentration differences caused by instantaneous large-scale mixing of the two materials. It allows the minced meat and extractant to come into more thorough contact, significantly improving the extraction efficiency. At the same time, it reduces the time and energy required for uniform mixing, ensuring the accuracy of the test results.
[0013] 2. Through the design of the impact component, the cylinder drives the impact plate to intermittently impact the meat scrap hopper. The cushioning effect of the rubber pad and the impact force can effectively prevent the meat scrap from clogging in the meat scrap hopper, ensuring that the meat scrap can smoothly pass through the meat outlet pipe into the mixing box. At the same time, the vibration generated by the impact can also make the meat scrap in the meat scrap hopper more evenly distributed, further improving the uniformity of the mixing of meat scrap and extractant, laying the foundation for the subsequent accurate detection of antibiotic residues in livestock and poultry meat.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Reference Figures 1-6 An antibiotic residue detection device for livestock and poultry meat includes a detection chamber 1, which is divided into a detection area and a mixing area by a partition 2. The partition 2 has an opening 3. The detection area is equipped with a detection component, and the mixing area is equipped with a stirring component and a feeding component. The stirring component includes a mixing box 51 fixed inside the detection chamber 1, and a top cover 52 is provided above the mixing box 51. An electric push rod for raising and lowering the top cover 52 is installed on the top of the detection chamber 1. The feeding component includes an extractant hopper 61 fixed to the top of the top cover 52. The bottom of the extractant hopper 61 is connected to a liquid outlet pipe 62. A meat scrap hopper 63 is fixed to the top of the top cover 52. The bottom of the meat scrap hopper 63 is connected to a meat outlet pipe 64. A sealing block 67 slides inside the liquid outlet pipe 62. A sealing plate 68 is provided below the meat outlet pipe 64. A meat leakage hole 69 is provided on the sealing plate 68. The diameter of the meat leakage hole 69 is larger than the diameter of the meat outlet pipe 64.
[0024] Furthermore, the stirring assembly also includes a stirring rod 53 rotatably connected to the top cover 52 via a bearing, and a motor for driving the stirring rod 53 to rotate is mounted on the top of the top cover 52.
[0025] Furthermore, the feeding assembly also includes a sector gear 65 fixed to the outer surface of the stirring rod 53, with a gear housing 66 meshing on the outer surface of the sector gear 65, a sealing block 67 fixed to the gear housing 66 by a connecting rod, and a sealing plate 68 fixed to the gear housing 66.
[0026] Furthermore, a limit strip 610 is fixed to the bottom of the top cover 52, and a limit block 611 is fixed to the gear housing 66. The limit block 611 slides on the outer surface of the limit strip 610.
[0027] Furthermore, the detection assembly includes a mounting plate 41 disposed in the detection area, an immunosensor 42 mounted on the bottom of the mounting plate 41, an electric push rod mounted on the detection chamber 1 for driving the mounting plate 41 to rise and fall, an extraction box 43 disposed below the mixing chamber 51, and an electric push rod mounted on the outer surface of the detection chamber 1 for driving the extraction box 43 to move below the immunosensor 42.
[0028] When testing for antibiotic residues in livestock and poultry meat, firstly, an electric push rod moves the top cover 52 down to the top of the mixing chamber 51. The motor is then started, driving the stirring rod 53 to rotate on the top cover 52 via bearings. Simultaneously, the sector gear 65 fixed to its outer surface rotates, meshing with the gear housing 66. This causes the gear housing 66 to slide linearly under the constraints of the limiting strip 610 and the limiting block 611. As the gear housing 66 moves, it causes the sealing block 67 to slide within the liquid outlet pipe 62, simultaneously moving the sealing plate 68. This structural design controls the feeding assembly. When the sealing block 67 moves away, the extractant in the extractant hopper 61 flows into the mixing chamber 51 through the liquid outlet pipe 62. When the meat leakage hole 69 of the sealing plate 68 aligns with the meat outlet pipe 64, the minced meat in the minced meat hopper 63 falls into the mixing chamber 51 through the meat outlet pipe 64 and the meat leakage hole 69. The movement sequence and timing of the gear housing 66 are controlled. The system enables the orderly addition of extractant and minced meat, avoiding instantaneous large-scale mixing. The stirring rod 53 continuously rotates to stir and mix the extractant and minced meat in the mixing box 51. After uniform mixing, the valve on the discharge pipe at the bottom of the mixing box 51 is activated, allowing the mixture to fall into the extraction box 43 below. At this time, the electric push rod on the outer surface of the detection box 1, which is used to move the extraction box 43, is activated, moving the extraction box 43 to the bottom of the mounting plate 41 below the immunosensor 42 in the detection area. Then, the electric push rod on the detection box 1, which is used to raise and lower the mounting plate 41, is activated, causing the mounting plate 41 to descend, bringing the immunosensor 42 close to the mixture in the extraction box 43, thereby detecting antibiotic residues in livestock and poultry meat. The immunosensor 42 is fixed with antibodies that specifically recognize antibiotics, which can specifically bind to antibiotics in the sample solution, generating electrical or optical signals, which are then transmitted to the display panel. This is existing technology and will not be described in detail here.
[0029] Based on Example 1, Example 2:
[0030] Reference Figures 1-6 ,
[0031] Furthermore, the top of the top cover 52 is provided with an impact assembly that vibrates the minced meat hopper 63. The impact assembly includes a cylinder 71 fixed to the top of the top cover 52, an impact disc 72 fixed to one end of the extension rod of the cylinder 71, and a rubber pad 73 fixed on the impact disc 72.
[0032] During the feeding process of minced meat, cylinder 71 is activated. The extension rod of cylinder 71 drives the impact plate 72 to intermittently impact the minced meat hopper 63. The rubber pad 73 on the impact plate 72 provides impact force while buffering, preventing minced meat from clogging in the minced meat hopper 63, allowing the minced meat to be fed smoothly, and the vibration makes the minced meat more evenly distributed in the minced meat hopper 63.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
