Description

Technical Field

[0001] This utility model relates to the field of rapid detection and sampling technology for pesticide and veterinary drug content, specifically a rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods. Background Technology

[0002] Pesticide residues are pesticides applied to crops. Some of these pesticides adhere to the crops, while others are dispersed in the soil, atmosphere, and water environment. Some of the pesticides remaining in the environment are absorbed by plants. Residual pesticides can directly reach livestock through plant fruits, water, or the atmosphere, or ultimately be passed on to humans and animals through the environment and the food chain. Therefore, it is necessary to sample and test the pesticide and veterinary drug content in food.

[0003] The prior art, disclosed in CN221100095U, provides a rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods. The device includes a workbench, a support column mounted on the top of the workbench, a hydraulic pump mounted on the bottom of the support column, a connecting platform connected to the bottom of the hydraulic pump, a support frame mounted on the top of the connecting platform, a movable column mounted on one end of the top of the support frame, a spring column mounted on the other end of the top of the movable column, and a sampling column mounted on the bottom of the connecting platform. This completes the food sampling process, reduces the overall operational steps, improves work efficiency, increases the convenience of the device, and reduces the burden on staff.

[0004] The aforementioned patent primarily utilizes a hydraulic pump to move a telescopic column at the output end, inserting a sampling column into the food to achieve sampling. However, due to the hollow structure of the sampling column, the food easily detaches from the column and falls after being cut. This falling food contaminates the water inside the washing tank, preventing the tank from effectively cleaning the sampling column and significantly reducing the practicality of the sampling device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods, comprising a device body divided into upper and lower layers. A rotating assembly is fixedly installed on the lower layer of the device body, and a controller and a sampling structure are fixedly installed on the upper layer. The sampling structure is used to sample food placed on the device body. The device body includes an outer shell with a drop hole at the center of its top for the sampled food to fall into. The rotating assembly includes a rotating turntable within the device body. A cleaning cylinder for cleaning the sampling structure is fixedly installed on the turntable. A support column is fixedly installed on the side of the turntable away from the cleaning cylinder. A receiving tray for collecting the sampled food is fixedly installed on the top of the support column. The larger diameter of the receiving tray allows food samples to fall directly onto it, significantly improving the efficiency of food collection in the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods.

[0007] Furthermore, the rotating assembly also includes a motor fixedly mounted at the bottom of the device body. A rotating shaft is fixedly mounted at the output end of the motor, and the turntable is fixedly mounted on the rotating shaft. The motor drives the rotation of the washing cylinder and the support column. This motor-driven rotation of the washing cylinder and support column enhances the integrated operation of the internal structure of the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods.

[0008] Furthermore, the sampling structure includes an electric actuator and a telescopic shaft fixedly installed on the top of the outer casing. A fixed plate is fixedly installed on the top of both the electric actuator and the telescopic shaft. Sampling components for cutting food are fixedly installed between multiple fixed plates. The fixed installation of sampling components for cutting food between multiple fixed plates makes the internal structure of the rapid detection sampling device for pesticide and veterinary drug content in animal-derived foods more robust and reliable, greatly improving the operational safety of the device.

[0009] Furthermore, a wire frame is fixedly installed on the top of the outer casing, and the controller is electrically connected to the electric actuator through the wire frame. This electrical connection allows the controller to directly control the electric actuator, enhancing the intelligence of the internal structure of the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods.

[0010] Furthermore, the sampling assembly includes connecting strips fixed on both sides to a fixed plate, with a hollow cylinder fixedly connected to the middle of the connecting strips. An inner groove is formed inside the hollow cylinder, and a pushing component is movably disposed within the inner groove. A removable top cover is fixedly installed on the top of the hollow cylinder. The removable top cover significantly improves the operability of the internal structure of the rapid detection sampling device for pesticide and veterinary drug content in animal-derived foods.

[0011] Furthermore, the pushing assembly includes a push cylinder located in the inner groove. A spring is fixedly installed at one end of the push cylinder near the top cover, and the end of the spring away from the push cylinder is fixedly installed on the top cover. A force-applying strip for the movable push cylinder is fixedly installed in the middle of the push cylinder. The force-applying strip in the middle of the push cylinder allows the user to directly squeeze the movable push cylinder using the force-applying strip, improving the ease of operation of the internal structure of the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods.

[0012] Furthermore, a food-cutting blade, which is ring-shaped, is fixedly connected to the end of the hollow cylinder furthest from the top cover. The ring shape of the blade allows for the cutting of food into cylindrical shapes, facilitating subsequent testing and enhancing the practicality of the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention makes the components of the cleaning and sampling device and the food sample collection device rotatable, so that after the cutting blade cuts off the food sample, the food sample will fall directly onto the food sample collection device instead of the cleaning and sampling device. This prevents the falling food sample from polluting the water source and greatly improves the practicality of the rapid detection sampling device for pesticide and veterinary drug content in animal-derived foods.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application provides a further detailed description. A rapid detection sampling device for pesticide and veterinary drug content in animal-derived food includes a device body 4, which has upper and lower layers. A rotating assembly 3 is fixedly installed on the lower layer of the device body 4, and a controller 1 and a sampling structure 2 are fixedly installed on the upper layer. The sampling structure 2 is used to sample food placed on the device body 4. The device body 4 includes an outer shell 43, with a drop hole 41 at the center of the top of the outer shell 43 for the sampled food to fall into. The rotating assembly 3 includes a turntable 32 that can rotate within the device body 4, and a sampling device is fixedly installed on the turntable 32. Structure 2 includes a cleaning cylinder 31, a turntable 32 with a support column 36 fixedly mounted on the side away from the cleaning cylinder 31, and a receiving tray 35 for collecting sampled food fixedly mounted on the top of the support column 36. The rotating assembly 3 also includes a motor 33 fixedly mounted on the bottom of the device body 4, with a rotating shaft 34 fixedly mounted on the output end of the motor 33. The turntable 32 is fixedly mounted on the rotating shaft 34. The motor 33 drives the rotation of the cleaning cylinder 31 and the support column 36. The sampling structure 2 includes an electric push rod 22 and a telescopic shaft 24 fixedly mounted on the top of the outer shell 43. 2. Fixed plates 21 are fixedly installed on the top of both the telescopic shaft 24 and the telescopic shaft 24. A sampling component 23 for cutting food is fixedly installed between multiple fixed plates 21. A wire frame 42 is fixedly installed on the top of the outer casing 43. The controller 1 is electrically connected to the electric push rod 22 through the wire frame 42. The sampling component 23 includes connecting strips 232 fixed on both sides of the fixed plates 21. A hollow cylinder 234 is fixedly connected to the middle of the connecting strips 232. An inner groove 236 is opened inside the hollow cylinder 234. A pushing component 233 is movably arranged in the inner groove 236 of the hollow cylinder 234. A removable top cover 231 is fixedly installed on the top of the cylinder 234. The pushing assembly 233 includes a push cylinder 2331 located in the inner groove 236. A spring 2332 is fixedly installed at one end of the push cylinder 2331 near the top cover 231. The end of the spring 2332 away from the push cylinder 2331 is fixedly installed on the top cover 231. A force strip 2333 for moving the push cylinder 2331 is fixedly installed in the middle position. A cutting blade 235 for cutting food is fixedly connected at one end of the hollow cylinder 234 away from the top cover 231. The cutting blade 235 is ring-shaped.

[0025] Since the hollow cylinder 234 is completely penetrated by the connecting strip 232 and is continuously hollow in the middle, one end of the spring 2332 is fixed to the top cover 231 and the other end is fixed to the push cylinder 2331. The push cylinder 2331 can move inside the push cylinder 2331. Therefore, when the user holds the force bar 2333 with both hands and applies downward force, the spring 2332 can be extended directly, and the push cylinder 2331 can move downward inside the push cylinder 2331, thereby pushing the food residue out of the hollow cylinder 234.

[0026] Since the cleaning cylinder 31 and the support column 36 rotate around the motor 33, and the rotation paths of the cleaning cylinder 31 and the support column 36 are both on the drop hole 41, the rotation of the motor 33 can make the cleaning cylinder 31 or the support column 36 located directly below the drop hole 41, thereby facilitating the cleaning of the hollow cylinder 234 and the collection of food samples.

[0027] The controller 1 contains a smart microcontroller control chip, which is electrically connected to the electric push rod 22 through the wire frame 42. Therefore, when the rapid detection sampling device for pesticide and veterinary drug content in animal-derived food needs to cut the food or clean the sampling component 23, the user can drive the electric push rod 22 through the controller 1 to make the sampling component 23 extend and retract accordingly.

[0028] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods are threaded. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. When using the rapid detection and sampling device for pesticide and veterinary drug content in animal-derived foods, the user places the food to be tested on the drop hole 41 of the outer shell 43. The user then drives the electric push rod 22 to retract via the controller 1. The retracted electric push rod 22 directly moves the sampling component 23 downwards until it reaches above the food. The food is then cut by the cutting blade 235, and the cut food falls through the drop hole 41 onto the receiving tray 35. At this time, the user applies downward force by holding the force bar 2333 with both hands, causing the push cylinder 2331 to move within the hollow cylinder 234, thereby partially removing the food sample. Food residue remaining in the hollow cylinder 234 is squeezed into the receiving tray 35 to collect food samples. The user then drives the motor 33 via the controller 1. The motor 33 swings the support column 36 outwards and aligns the washing cylinder 31 with the drop hole 41. The user can then remove the food residue from the receiving tray 35 for testing the pesticide and veterinary drug content in animal-derived foods. The user then drives the electric push rod 22 again, which directly inserts the sampling component 23 into the washing cylinder 31 and moves it up and down to clean the bottom of the sampling component 23. This structure ensures that food does not fall directly into the washing cylinder 31 during use, thus preventing contamination of the water inside the washing tank and greatly improving the practicality of the device.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
