Abstract
Description
Technical Field
[0001] This utility model relates to the field of rapid sampling technology for food testing, specifically a rapid sampling device for food testing. Background Technology
[0002] Sampling is a crucial step in food testing. Traditional food sampling methods often rely on manual operation with simple tools, which has many drawbacks. For example, sampling is inefficient for foods of different textures and shapes, making it difficult to quickly obtain sufficient and representative samples; it is also difficult to accurately control the sampling amount and depth during sampling, which can easily lead to sample bias and affect the accuracy of test results; moreover, the operation is cumbersome and labor-intensive, making it unsuitable for large-scale food testing.
[0003] When using existing rapid sampling devices for food testing,
[0004] (1) It is difficult to adapt to the food sampling needs at different heights and positions. When faced with food placed on high shelves or buried deep at the bottom of containers, the device is difficult to adjust the sampling position flexibly, which leads to inconvenience in sampling. Furthermore, the device or food may be damaged due to forced operation, affecting the accuracy and efficiency of sampling.
[0005] (2) The sample collection process is not convenient and efficient enough. When transferring the sample to the storage container after sampling, problems such as sample spillage, contamination, or sample loss due to cumbersome operation may occur, which reduces the integrity and reliability of the sample and thus affects the accuracy of subsequent test results.
[0006] To address the above problems, this utility model provides a rapid sampling device for food testing. Utility Model Content
[0007] The purpose of this invention is to provide a rapid sampling device for food testing. This invention can adapt to the food sampling needs at different heights and positions and can quickly collect samples, thereby solving the problems in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a rapid sampling device for food testing, comprising a control column, a sliding rod slidably connected to one end of the control column, a fixed box fixedly connected to one end of the sliding rod, a motor assembly fixedly connected to one end of the fixed box, a threaded rod fixedly connected to one end of the motor assembly, a sampling box threadedly connected to the surface of the threaded rod, and a collection component fixedly connected to the middle of the bottom end of the fixed box.
[0009] Furthermore, the motor assembly includes a motor box fixedly connected to one end of the fixed box, and a servo motor is fixedly connected inside the motor box. The output end of the servo motor is splinedly connected to a transmission rod, thereby providing precise power to the sampling box to achieve accurate sampling.
[0010] Furthermore, the collection assembly includes a fixed rod fixedly connected to the middle of the bottom of the fixed box, a rotating plate rotatably connected to the bottom end of the fixed rod, and a placement bag fixedly connected to one end of the rotating plate, thereby achieving the function of convenient and quick collection and storage of samples.
[0011] Furthermore, a bearing is fixedly connected to one end of the positive and negative threaded rod, and one end of the bearing is fixedly connected to the inner wall of the fixed box, which achieves the function of ensuring the stable rotation of the positive and negative threaded rod.
[0012] Furthermore, a limit rod is threadedly connected to one side of the top of the control column, and a limit hole is formed on the surface of the sliding rod, so as to fix the position of the sliding rod to adapt to sampling at different heights.
[0013] Furthermore, a connecting block is fixedly connected to the other end of the control column, and a hanging rope is fixedly connected to the surface of the connecting block, which facilitates the storage and retrieval of the device.
[0014] Furthermore, an anti-slip sleeve is fitted onto the other side of the top of the control column. The anti-slip sleeve is made of sponge, which enhances the stability of the operator's grip.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model provides a rapid sampling device for food testing.
[0017] (1) By setting up the control column and sliding rod, when the operator needs to sample food at different heights, the operator can easily adjust the position of the sliding rod on the control column. When sampling food on different layers of supermarket shelves, if the operator wants to sample food at a higher position on the top layer, the operator can first extend the sliding rod so that the sampling box can reach the corresponding height.
[0018] (2) By setting up the collection component, when the sampling box completes the sampling, the sample can fall directly into the placement bag of the collection component when the personnel operate the device. For example, when sampling powdered food such as flour, after the sampling box collects the flour, the placement bag is adjusted to a suitable angle by rotating the plate, and the flour will fall into the placement bag smoothly without spilling or contaminating other parts.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] To solve the problem of how to effectively position and adjust the technology, such as Figure 1-5 As shown, the following preferred technical solutions are provided:
[0027] A rapid sampling device for food testing includes a control column 1, with a sliding rod 2 slidably connected to one end of the control column 1. By configuring the control column 1 and the sliding rod 2, when personnel operate the device, they can easily adjust the position of the sliding rod 2 on the control column 1 to sample food at different heights. When sampling food from different shelves in a supermarket, if sampling is required from the top shelf, the sliding rod 2 can be extended to allow the sampling box 6 to reach the corresponding height. A fixing box 3 is fixedly connected to one end of the sliding rod 2, and a motor assembly 4 is fixedly connected to one end of the fixing box 3. One end of the motor assembly 4 is fixedly connected to a positive and negative threaded rod 5, and a sampling box 6 is threadedly connected to the surface of the positive and negative threaded rod 5. A collection component 7 is fixedly connected to the middle of the bottom end of the fixed box 3. With the setting of the collection component 7, when the sampling box 6 completes sampling, the sample can fall directly into the placement bag 703 of the collection component 7. For example, when sampling powdered food such as flour, after the sampling box 6 collects the flour, the placement bag 703 is adjusted to a suitable angle by the rotating plate 702, and the flour will fall smoothly into the placement bag 703 without spillage or contamination of other parts.
[0028] Specifically, when operating the device, the operator first adjusts the extension length of the sliding rod 2 on the control column 1 according to the height of the food to be sampled. The initial height position of the sampling box 6 is determined by screwing the limiting rod 9 into the corresponding limiting hole of the sliding rod 2. Then, according to the type of food and sampling requirements, the motor assembly 4 is started, so that the sampling box 6 moves to a suitable position on the positive and negative threaded rod 5 for sampling. After sampling, the sampling box 6 is moved above the collection assembly 7. The angle of the placement bag 703 is adjusted by rotating the rotating plate 702 so that the collected sample falls into it smoothly. During the operation, the operator can hold the control column 1 stably with the anti-slip sleeve 12. When the device is not in use, the device can be hung up and stored using the suspension rope 11 on the connecting block 10.
[0029] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0030] The motor assembly 4 includes a motor box 401 fixedly connected to one end of the fixed box 3. A servo motor 402 is fixedly connected inside the motor box 401. The output end of the servo motor 402 is splinedly connected to a transmission rod 403. The purpose of this design is to provide a precise and stable rotational power source for the positive and negative threaded rod 5, thereby accurately controlling the movement of the sampling box 6. The servo motor 402 can precisely drive the transmission rod 403 to rotate at a specific angle and speed according to a preset program or operator's instructions.
[0031] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:
[0032] The collection component 7 includes a fixed rod 701 fixedly connected to the middle of the bottom of the fixed box 3. A rotating plate 702 is rotatably connected to the bottom of the fixed rod 701. A placement bag 703 is fixedly connected to one end of the rotating plate 702. The purpose of this design is to achieve convenient and efficient sample collection and storage, while adapting to different sampling scenarios. The rotating plate 702 can rotate flexibly around the fixed rod 701, and the receiving angle of the placement bag 703 can be adjusted according to the position of the sampling box 6 and the characteristics of the food sample. For example, when sampling liquid food such as honey, the rotating plate 702 can be rotated to a suitable tilt angle so that the honey dripping from the sampling box 6 can flow smoothly into the placement bag 703, avoiding sample spillage and contamination.
[0033] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0034] One end of the threaded rod 5 is fixedly connected to a bearing 8, and one end of the bearing 8 is fixedly connected to the inner wall of the fixed box 3. The purpose of this design is to ensure the smoothness and stability of the rotation of the threaded rod 5, and to reduce frictional resistance and mechanical wear. The bearing 8 uses high-precision balls or needle rollers, and the rolling elements inside it can effectively reduce the coefficient of friction when the threaded rod 5 rotates, so that the threaded rod 5 can rotate smoothly and efficiently.
[0035] Furthermore, such as Figure 5 As shown, the following preferred technical solutions are provided:
[0036] A limit rod 9 is threadedly connected to one side of the top of the control column 1, and a limit hole is opened on the surface of the sliding rod 2. The purpose of this design is to achieve precise locking of the position of the sliding rod 2 to adapt to the food sampling needs at different heights. The sliding range of the sliding rod 2 on the control column 1 can be set according to the actual application scenario, within the extension range of 0 to 50 cm.
[0037] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0038] The other end of the control column 1 is fixedly connected to a connecting block 10, and a hanging rope 11 is fixedly connected to the surface of the connecting block 10. The purpose of this design is to facilitate the storage, handling and transfer of the device. The connecting block 10 and the control column 1 are integrally formed from a sturdy and lightweight material such as aluminum alloy to ensure the stability of the connection.
[0039] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0040] On the other side of the top of the control column 1, there is an anti-slip sleeve 12. The anti-slip sleeve 12 is made of sponge. The purpose of this design is to enhance the comfort and stability of the operator when holding the control column 1. The sponge has good elasticity and coefficient of friction, and the texture of its surface can further increase the friction with the hand.
[0041] Working principle: The servo motor 402 drives the transmission rod 403 to rotate according to the control signal, which in turn drives the positive and negative threaded rod 5 to rotate, so that the sampling box 6 moves linearly on the positive and negative threaded rod 5 according to the thread relationship, realizing accurate sampling of food. The sliding rod 2 can slide on the control column 1 and be fixed by the limit rod 9 to adjust the height position of the sampling box 6. The collection component 7 collects samples with the help of the rotating plate 702 and the placement bag 703. The bearing 8 ensures smooth rotation of the positive and negative threaded rod 5. The connecting block 10 and the suspension rope 11 are used for device storage. The anti-slip sleeve 12 helps the operator to hold the device stably. All components of the entire device work together to realize rapid and accurate sampling and sample collection of different types and heights of food, meet the diverse needs of food testing, and improve the overall efficiency and quality of food testing.
