Description

Technical Field

[0001] This invention relates to the field of biomedical detection technology, specifically to a biomedical instrument and method for detecting Salmonella in livestock and poultry farming. Background Technology

[0002] Salmonella is a group of pathogenic bacteria that widely parasitizes livestock and poultry in their bodies and farming environments. Its transmission routes are extensive, spreading through contaminated feed, drinking water, and farming equipment, causing enteritis, septicemia, and other diseases in livestock and poultry, significantly reducing survival rates and severely impacting the economic benefits of the livestock and poultry farming industry. Simultaneously, Salmonella can enter the human body through livestock and poultry products (such as meat, eggs, and milk), inducing acute gastroenteritis, fever, and other symptoms, seriously threatening food safety and public health. Therefore, rapid and accurate detection of Salmonella throughout the entire livestock and poultry farming process is a crucial link in ensuring both farming efficiency and food safety.

[0003] However, existing Salmonella detection instruments and methods still have certain problems in use: A Chinese patent publication number CN202021722902.3 discloses a Salmonella detection device for meat and egg products, which belongs to the field of detection equipment technology. It includes a support base, a detection base, an incubation box, a handle, and a connecting rod. The support base is located below the detection base and is fixedly connected to the detection base.

[0004] Currently, batch testing for Salmonella requires placing petri dishes sequentially, which is relatively cumbersome and inefficient. Furthermore, frequent handling of the petri dishes can lead to accidental contact with the surface, causing stains and affecting the clarity of subsequent observations.

[0005] To address the aforementioned issues, an innovative design was developed based on existing biomedical-based instruments and methods for detecting Salmonella in livestock and poultry farming. Summary of the Invention

[0006] The purpose of this invention is to provide a biomedical-based Salmonella detection instrument and method for livestock and poultry farming, in order to solve the problems mentioned in the background art, such as low efficiency in batch detection of existing Salmonella detection devices, the need for frequent handling by operators, and cumbersome operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a biomedical-based Salmonella detection instrument for livestock and poultry farming, comprising a detection stage and an electron microscope mounted on its upper middle section. The upper end of the detection platform is provided with a conveying component for continuous feeding of the culture dish. The conveying component includes two sets of rotating rods connected to the detection platform. The upper end of the rotating rods is connected to a synchronous pulley, and a feeding belt is connected between the synchronous pulleys. A limiting component is connected to the outer wall of the feeding belt, and the limiting component can engage with the culture dish. A guide frame is provided on the rear side of the conveying component. A collection frame is connected to the left side of the guide frame, and a feeding component is connected to the right side of the guide frame. The feeding component includes a feeding frame, and a feeding tray is provided inside the feeding frame. The feeding tray is connected to the synchronous belt pulley on the right side. A cleaning component is located on the right side of the electron microscope, which is used to clean stains on the surface of the petri dish.

[0008] Preferably, the lower end of the rotating rod is rotatably connected to the testing platform, the bottom of the left rotating rod penetrates the testing platform, a first motor is installed at the lower left end of the testing platform, and the shaft end of the first motor is connected to the left rotating rod.

[0009] By adopting the above technical solution, the first motor provides stable and controllable power to the rotating rod, driving the left rotating rod to rotate. In turn, the synchronous pulley drives the feeding belt to rotate at a uniform speed, realizing the automated continuous feeding of petri dishes, replacing manual feeding operations, effectively improving feeding efficiency, and meeting the large-scale testing needs of large-scale livestock and poultry farming. At the same time, the rotating rod is rotatably connected to the detection platform, ensuring the stability of the rotating rod's operation and preventing the feeding belt from shaking and causing the petri dishes to shift or tip over. This provides a stable transport guarantee for subsequent accurate electron microscopy observation and reduces human operation errors.

[0010] Preferably, the limiting component includes a limiting frame, and two sets of limiting frames are provided, with the limiting frames conforming to the outer wall of the culture dish.

[0011] Using the above technical solution, the two sets of limiting frames fit into the outer wall of the culture dish, which can accurately limit the culture dish during the transportation process, firmly lock the culture dish, and prevent the culture dish from swaying, shifting or tipping over during transportation and testing. This ensures that the culture dish is always within the observation range of the electron microscope, guarantees the accuracy of the detection position, reduces detection errors caused by culture dish displacement, and improves the accuracy of Salmonella detection.

[0012] Preferably, the outer wall of the feeding belt is rotatably connected to a connecting rod, and the connecting rod is rotatably connected to the limiting frame.

[0013] With the above technical solution, the connecting rod, the feeding belt, and the limiting frame are all rotatably connected, giving the limiting frame flexible rotation adjustment capability. This allows it to adapt to culture dishes of different specifications and sizes, expanding the applicability of the equipment. There is no need to replace the limiting components with special ones for different sizes of culture dishes, reducing the cost of equipment use. At the same time, the rotatable connection reduces hard friction between the limiting frame and the outer wall of the culture dish, avoiding scratches on the surface of the culture dish, protecting the integrity of the culture dish and the internal culture sample, and preventing sample contamination from affecting the test results.

[0014] Preferably, the inner wall of the flow guide frame has a groove, and the flow guide rods are distributed in an equidistant array inside the groove. The flow guide rods are in contact with the outer wall of the culture dish. The two ends of the flow guide frame are designed with arcs, and the flow guide frame is adapted to the movement trajectory of the culture dish during detection.

[0015] Using the above technical solution, the guide rods are evenly distributed in an array and contact the outer wall of the culture dish, which can further assist in positioning during the transfer of the culture dish, avoid the culture dish from shifting, and ensure the stability of the transfer trajectory. The rounded design at both ends of the guide frame is adapted to the movement trajectory of the culture dish during detection, which can reduce the collision and wear between the culture dish and the end of the guide frame, and protect the culture dish. At the same time, the guide structure can guide the culture dish smoothly into the collection frame or subsequent processing stage, making the transfer and collection of the culture dish smoother and improving the continuity of the overall detection process.

[0016] Preferably, a feeding groove is provided on the outer wall of the feeding tray, which is adapted to the culture dish. A feeding pipe is fixed at the upper right end of the feeding frame, and the feeding pipe has an opening on the right side, with the inner wall of the feeding pipe adapted to the culture dish.

[0017] By adopting the above technical solution, the feeding tube is designed with an opening on the right side and its inner wall is adapted to the culture dish, which can realize the orderly feeding of culture dishes and avoid stacking and congestion caused by feeding multiple culture dishes at the same time. The feeding groove on the outer wall of the feeding tray is adapted to the culture dish, which can accurately receive the culture dish falling from the feeding tube, realize the precise feeding of a single culture dish at a time, ensure that the feeding rhythm is controllable, match the continuous conveying of the conveying component, avoid feeding chaos affecting the detection efficiency, and improve the accuracy of feeding, thus preparing for subsequent detection.

[0018] Preferably, the lower end of the feeding tray extends to the lower end of the testing table, the lower end of the feeding tray is connected to the driven pulley, the lower end of the rotating rod on the right side is connected to the driving pulley, and a transmission belt is connected between the driving pulley and the driven pulley.

[0019] By adopting the above technical solution, the feeding disc is synchronously driven by the power of the rotating rod in the conveying component through the cooperation of the active pulley, driven pulley and transmission belt. There is no need to set up an additional independent power source to drive the feeding disc, which simplifies the overall structure of the equipment and reduces the manufacturing cost and energy consumption. At the same time, it realizes the synchronous linkage between the feeding action and the conveying action, ensuring that the feeding rhythm is consistent with the conveying rhythm, avoiding problems such as conveying interruption and culture dish tipping caused by feeding delay or advance, and improving the integration level and operational stability of the equipment.

[0020] Preferably, the cleaning component includes a protective cover fixed to the guide frame, limiting rollers connected to both sides inside the protective cover, a guide roller connected to the bottom of the protective cover, and a non-woven fabric strip connected between the two sets of limiting rollers, with the non-woven fabric strip wrapped around the bottom of the guide roller.

[0021] Using the above technical solution, the non-woven fabric strip can quickly wipe away stains, dust, or residual samples on the surface of the petri dish, avoiding interference from residual stains on the imaging quality of the electron microscope, preventing misjudgment of detection results due to blurred imaging, and improving detection accuracy; the guide roller can limit and tension the non-woven fabric strip to ensure full contact between the non-woven fabric strip and the surface of the petri dish, ensuring uniform cleaning effect; the protective cover can prevent unused non-woven fabric strips from becoming contaminated.

[0022] Preferably, a second motor is installed on the right side of the protective cover, and the shaft end of the second motor is connected to the limiting roller on the right side. A guide tube is fixed inside the protective cover, and a liquid storage tank is connected to the upper end of the protective cover. The top of the guide tube is connected to the liquid storage tank. A limiting wheel is rotatably installed inside the guide tube. The outer wall of the limiting wheel is arrayed with feeding grooves. The limiting wheel is adapted to the inner wall of the guide tube. The lower end of the guide tube's drain port is attached to the non-woven fabric strip. The front end of the limiting wheel is connected to the first gear, and the front end of the limiting roller on the right side is connected to the second gear. The first gear and the second gear mesh. The right end of the protective cover is connected to an infrared sensor. The infrared sensor can detect the culture dish and start the second motor to rotate.

[0023] Using the above technical solution, the infrared sensor can automatically detect the position of the petri dish. When the petri dish reaches the cleaning position, the second motor is automatically started, realizing the automated triggering of the cleaning action without manual control, saving labor costs and improving the automation level of the detection process. While the second motor drives the limiting roller to rotate, the meshing of the first gear and the second gear drives the material limiting wheel to rotate, so that the feeding of the cleaning liquid and the rotation of the non-woven fabric strip are synchronized. The feeding groove on the material limiting wheel can accurately control the amount of cleaning liquid fed, avoiding waste of cleaning liquid, while ensuring that the cleaning liquid is evenly attached to the non-woven fabric strip, improving the cleaning effect, further ensuring clear electron microscope imaging, and ensuring accurate and reliable detection results. At the same time, the material limiting grooves opened in the array can realize the intermittent feeding of cleaning liquid, and the non-woven fabric is cleaned in dry and wet sections, which can wipe away the residual cleaning liquid stains during cleaning.

[0024] A biomedical-based method for detecting Salmonella used in livestock and poultry farming includes the following steps: Step 1: A continuous feeding structure consisting of a transport component and a feeding component is set below the electron microscope, which can transfer and transport the petri dish sample to the electron microscope detection area. Step 2: Manually load the culture dishes to be tested onto the continuous loading structure. The culture dishes are transferred sequentially through the continuous loading structure. When testing in batches, this avoids frequent manual loading and unloading, reducing the complexity of operation and the detection error caused by human intervention. Step 3: The conveyor component sets up a cleaning component to clean the surface of the petri dishes during the feeding process, removing stains left on the surface of the petri dishes during manual operation, and improving the accuracy of subsequent observation and judgment.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: This biomedical-based Salmonella detection instrument and method for livestock and poultry farming provides stable power to the conveying component through a first motor, and in conjunction with the transmission of the synchronous pulley and the feeding belt, realizes continuous automatic conveying of the culture dishes; the feeding component, through the linkage of the active pulley, the driven pulley and the transmission belt, uses the power of the conveying component to synchronously complete the precise feeding of a single culture dish, without the need for an additional power source, simplifying the structure while achieving the coordination and consistency of the feeding and conveying rhythm, effectively adapting to the large-scale Salmonella detection needs of large-scale livestock and poultry farming, completely replacing traditional manual feeding and transfer operations, and reducing operational errors caused by manual intervention.

[0026] 1. Two sets of limiting frames precisely fit the outer wall of the culture dish, and the rotating connection design of the connecting rod can not only achieve stable positioning of the culture dish during transportation, preventing it from shifting or tipping over; the guide rod and arc-shaped end design in the guide frame further assist in the precise transportation of the culture dish, reduce collision and wear, and ensure that the culture dish is always within the observation range of the electron microscope, providing a guarantee for the accurate detection of Salmonella, while avoiding problems such as scratches on the culture dish and sample contamination, thus improving the accuracy of the test results; 2. The cleaning component wipes the stains on the surface of the petri dish with non-woven fabric strips. With the limiting and tensioning effect of the limiting roller and guide roller, the cleaning effect is ensured to be uniform. The infrared sensor realizes the automatic triggering of the cleaning action. The second motor drives the limiting wheel to complete the precise and intermittent feeding of the cleaning liquid, which not only avoids the waste of cleaning liquid, but also eliminates water stains by cleaning the non-woven fabric in dry and wet sections, preventing the stains from interfering with the electron microscope imaging.

[0029] 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.

[0030] Example 1, please refer to Figure 1-10This invention provides a technical solution: a biomedical Salmonella detection instrument for livestock and poultry farming, comprising a detection stage 1 and an electron microscope 2 mounted on its upper middle part. A conveying assembly 3 is provided on the upper part of the detection stage 1 for continuous feeding of culture dishes. The conveying assembly 3 includes two sets of rotating rods 301 connected to the detection stage 1. Synchronous pulleys 302 are connected to the upper ends of the rotating rods 301, and a feeding belt 303 is connected between the synchronous pulleys 302. A limiting assembly is connected to the outer wall of the feeding belt 303. Component 4, the limiting component 4, can engage with the petri dish; the lower end of the rotating rod 301 is rotatably connected to the detection stage 1, the bottom of the left rotating rod 301 penetrates the detection stage 1, the lower left end of the detection stage 1 is equipped with a first motor 304, the shaft end of the first motor 304 is connected to the left rotating rod 301; the limiting component 4 includes a limiting frame 401, two sets of limiting frames 401 are provided, the limiting frame 401 fits into the outer wall of the petri dish; the outer wall of the feeding belt 303 is rotatably connected to the connecting rod 402, the connecting rod 402 is rotatably connected to the limiting frame 401. This equipment achieves the detection needs of large-scale Salmonella in livestock and poultry breeding through autonomous feeding, improving detection efficiency and ease of operation. In use, the petri dish is continuously fed through the conveying component 3, and the operator uses an electron microscope 2 to observe and determine whether the test sample carries Salmonella. The conveying assembly 3 is powered by a first motor 304, which drives the left rotating rod 301 to rotate. The two sets of rotating rods 301 are connected to the feeding belt 303 via a synchronous pulley 302 at their upper ends, ensuring synchronized rotation. Grooves and protrusions are correspondingly provided between the feeding belt 303 and the synchronous pulley 302 to maintain synchronized rotation and prevent slippage. During the rotation of the feeding belt 303, a connecting rod 402 drives a limiting frame 401 to follow. When the culture dish is engaged with the limiting frame 401, the limiting frame 401 can move the culture dish to feed the food, solving the tedious manual feeding problem during batch testing.

[0031] A guide frame 5 is installed on the rear side of the conveying component 3. The left side of the guide frame 5 is connected to the collection frame 6, and the right side of the guide frame 5 is connected to the feeding component 7. A groove is opened on the inner wall of the guide frame 5, and guide rods 8 are evenly distributed in an array inside the groove. The guide rods 8 contact the outer wall of the culture dish. The two ends of the guide frame 5 are designed with arcs to match the movement trajectory of the culture dish during detection. After the feeding component 7 feeds the culture dish, the feeding belt 303 drives the limiting frame 401 to rotate and engage with the culture dish. During continuous rotation, the guide frame 5 limits and guides the flow. The limiting frame 401 and the guide frame 5 limit the two sides of the culture dish, allowing the culture dish to move along a preset trajectory. When the culture dish moves to below the electron microscope 2, it stops moving for detection. After detection, it continues to move along the guide frame 5. When it moves to the end of the guide frame 5, the culture dish moves into the collection frame 6 for further processing. The guide rods 8 arranged in an array inside the guide frame 5 rotate with the petri dish as it moves, which can reduce wear during the movement of the petri dish and avoid wear on the outer wall caused by continuous friction between the petri dish and the inside of the guide frame 5 during the feeding process.

[0032] The feeding assembly 7 includes a feeding frame 701, inside which a feeding tray 703 is installed. The feeding tray 703 is connected to the right-side synchronous pulley 302. A feeding groove is formed on the outer wall of the feeding tray 703, which is adapted to the petri dish. A discharge pipe 702 is fixed to the upper right side of the feeding frame 701. The discharge pipe 702 has an opening on the right side, and its inner wall is adapted to the petri dish. The lower end of the feeding tray 703 extends to the lower end of the detection stage 1. The lower end of the feeding tray 703 is connected to a driven pulley 704, and the lower end of the right-side rotating rod 301 is connected to a driving pulley 706. A transmission connection is established between the driving pulley 706 and the driven pulley 704. The belt 705 and the feeding frame 701 are used for continuous feeding of the culture dishes and to ensure that the culture dishes can smoothly engage with the limiting frame 401. The culture dishes to be tested are placed inside the discharge tube 702. When the feeding belt 303 rotates, the drive pulley 706 connected to the lower end of the right rotating rod 301 rotates synchronously. The drive pulley 706 drives the driven pulley 704 and the feeding tray 703 to rotate synchronously through the transmission belt 705. The outer wall of the feeding tray 703 has a notch. When the notch rotates to below the discharge tube 702, the culture dish falls into the notch and is transferred as the feeding tray 703 continues to rotate. Because the feeding belt 303 and the feeding tray 703 are linked by a belt structure, it can be ensured that the culture dish can smoothly engage with the limiting frame 401 during the rotation of the feeding tray 703. After rotating a certain angle, the culture dish is guided by the guide frame 5 and enters the guide frame 5. The drive pulley 706, driven pulley 704 and drive belt 705 are provided with matching grooves and protrusions to maintain synchronous transmission and prevent slippage during transmission.

[0033] A cleaning component 9 is installed on the right side of the electron microscope 2. The cleaning component 9 is used to clean stains on the surface of the petri dish. The cleaning component 9 includes a protective cover 901 fixed to the flow guide frame 5. Limiting rollers 902 are connected to both sides inside the protective cover 901. A guide roller 903 is connected to the bottom of the protective cover 901. A non-woven fabric strip is connected between the two sets of limiting rollers 902. The non-woven fabric strip is wrapped around the bottom of the guide roller 903. A second motor 910 is installed on the right side of the protective cover 901. The shaft end of the second motor 910 is connected to the right-side limiting roller 902. A guide tube 905 is fixed inside the protective cover 901. The upper end of the protective cover 901 is connected to a liquid storage tank 908. The top of the guide tube 905 is connected to the liquid storage tank 908. A limiting wheel 906 is rotatably installed inside the guide tube 905. The outer wall of the limiting wheel 906 has arrayed feeding grooves 907. The limiting wheel 906 is adapted to the inner wall of the guide tube 905. The lower end of the guide tube 905 has a drain port that is in contact with a non-woven fabric strip. The front end of the limiting wheel 906 is connected to a first gear 909. The front end of the right-side limiting roller 902 is connected to a second gear 911. The first gear 909 and the second gear 911 mesh. An infrared sensor 904 is connected to the right end of the protective cover 901. When the infrared sensor 904 detects the culture dish, it starts the second motor 910 to rotate. To ensure clear imaging during observation and testing using the electron microscope 2, a cleaning structure is provided to clean the surface of the culture dish. When the limiting frame 401 drives the culture dish to move below the cleaning assembly 9, the infrared sensor 904 senses the culture dish and sends a signal to the control system. The control system controls the second motor 910 to rotate, driving the right limiting roller 902 to rotate. The right limiting roller 902 is used for non-woven fabric winding, and the left limiting roller 902 is used for non-woven fabric unwinding. The rotation of the limiting roller 902 achieves cleaning of the culture dish surface, and the guide roller 903 maintains effective contact between the non-woven fabric and the culture dish surface, and, in conjunction with the winding of the non-woven fabric, improves the cleaning effect. During the nonwoven fabric cleaning process, the right-side limiting roller 902 drives the second gear 911 to rotate. The second gear 911 then drives the first gear 909 and the limiting wheel 906 to rotate. When the limiting wheel 906 rotates, the cleaning liquid inside the storage tank 908 flows into the groove on the outer wall of the limiting wheel 906. After the groove rotates to the bottom, the internal cleaning liquid flows to the nonwoven fabric through the guide pipe 905. Wetting the nonwoven fabric improves the cleaning effect. The cleaning liquid used is sterile distilled water or a special biological detection cleaning liquid. To avoid residual water stains, the grooves are arranged in an array, which allows for dry and wet separation of the nonwoven fabric. The dry section can remove water stains, and the combination of dry and wet cleaning maintains high efficiency.

[0034] Example 2: The present invention provides a technical solution: The difference between this example and Example 1 is that a labeling mechanism is provided on the left side of the electron microscope 2. A small self-adhesive labeling machine is selected and installed on the surface of the detection stage 1 through a bracket or frame. The labeling machine is adjusted to a suitable position. Because the limiting components 4 connected to the outer wall of the feeding belt 303 are evenly distributed, when a culture dish is detected under the electron microscope 2, the position of the culture dish after the previous group of tests is constant. Adjusting the position of the labeling mechanism ensures that the culture dish after the previous group of labels can be successfully labeled. With the help of the manual control button, when Salmonella is detected, manual control is used to label the culture dish, which facilitates subsequent classification and processing and improves the ease of operation.

[0035] A biomedical-based method for detecting Salmonella used in livestock and poultry farming includes the following steps: Step 1: A continuous feeding structure consisting of a conveying component 3 and a feeding component 7 is set below the electron microscope 2, which can transfer and transport the petri dish sample to the electron microscope detection area. Step 2: Manually load the culture dishes to be tested onto the continuous loading structure. The culture dishes are transferred sequentially through the continuous loading structure. When testing in batches, this avoids frequent manual loading and unloading, reducing the complexity of operation and the detection error caused by human intervention. Step 3: The conveying component 3 sets up a cleaning component 9 to clean the surface of the petri dishes during the feeding process, removing any stains left on the surface of the petri dishes during manual operation, and improving the accuracy of subsequent observation and judgment.

A biomedical-based Salmonella detection instrument for livestock and poultry farming according to claim 8, characterized in that: A second motor (910) is installed on the right side of the protective cover (901). The shaft end of the second motor (910) is connected to the right-side limiting roller (902). A guide pipe (905) is fixed inside the protective cover (901). The upper end of the protective cover (901) is connected to a liquid storage tank (908). The top of the guide pipe (905) is connected to the liquid storage tank (908). A limiting wheel (906) is rotatably installed inside the guide pipe (905). The outer wall of the limiting wheel (906) is arrayed with a feeding groove (907). The limiting wheel (906) is adapted to the inner wall of the guide pipe (905). The lower end of the guide pipe (905) is attached to the non-woven fabric strip. The front end of the limiting wheel (906) is connected to the first gear (909), and the front end of the limiting roller (902) on the right side is connected to the second gear (911). The first gear (909) and the second gear (911) mesh. The right end of the protective cover (901) is connected to the infrared sensor (904). After the infrared sensor (904) detects the culture dish, it starts the second motor (910) to rotate.

10. The method for detecting Salmonella for livestock and poultry farming based on biomedicine, as described in claim 1, is characterized in that: Includes the following steps: Step 1: The electron microscope (2) is equipped with a continuous feeding structure consisting of a conveying component (3) and a feeding component (7), which can transfer and transport the petri dish sample to the electron microscope detection area; Step 2: Manually load the culture dishes to be tested onto the continuous loading structure. The culture dishes are transferred sequentially through the continuous loading structure. When testing in batches, this avoids frequent manual loading and unloading, reducing the complexity of operation and the detection error caused by human intervention. Step 3: Conveying component (3) Setting up cleaning component (9) Cleaning the surface of the petri dish during the feeding process, removing the stains left on the surface of the petri dish during manual operation, and improving the accuracy of subsequent observation and judgment.
