Description

Technical Field

[0001] This utility model relates to the field of pesticide residue detection technology, and more specifically, to a sample separation device for pesticide residue detection. Background Technology

[0002] Pesticides are used in agricultural production to control pests and diseases and regulate plant growth, significantly improving crop yield and quality. However, improper use may lead to excessive pesticide residues. Pesticide residue testing is a key link in ensuring the quality and safety of agricultural products and food. It aims to use scientific methods to determine the content of pesticide residues and their metabolites and degradation products in food or the environment in order to assess whether they meet national or international safety standards. However, existing technologies have some problems: pesticide residue detection requires sample separation to reduce the impact of random errors on the results. Existing separation methods usually involve manual separation of individual samples. However, the separation process requires ensuring uniform sample distribution, which makes manual separation slow and cumbersome. Therefore, we propose a sample separation device for pesticide residue detection. Utility Model Content

[0003] One objective of this invention is to provide a new technology solution for a pesticide residue detection sample separation device.

[0004] According to a first aspect of this utility model, a sample separation device for pesticide residue detection is provided, comprising a housing, a groove on the housing, a support platform rotatably connected within the groove, a driving assembly inside the housing for driving the support platform to rotate, a support column fixedly connected to the support platform, a fixed platform movably connected to the support column, an adjusting assembly on the support column, multiple sets of fixing holes on the fixed platform, fixing clamps movably connected within the fixing holes, a liquid storage cylinder fixedly connected inside the housing, an injection pipe fixedly connected to one end of the liquid storage cylinder, a drain pipe fixedly connected to the other end of the liquid storage cylinder, a drain head fixedly connected to one end of the drain pipe, the drain head movably connected to the housing, and an electric valve fixedly connected to the drain head.

[0005] Optionally, the drive assembly includes a drive motor, which is fixedly connected inside the housing, and a dial is fixedly connected to the output end of the drive motor.

[0006] Optionally, a rotating shaft is fixedly connected to the fixed platform, the rotating shaft is rotatably connected to the outer casing, and a grooved wheel is fixedly connected to the rotating shaft, the grooved wheel engaging with the dial.

[0007] Optionally, the adjusting assembly includes a lead screw, a groove is provided on the support column, the fixed platform is slidably connected in the groove, the lead screw is rotatably connected in the groove, the lead screw is threadedly connected to the fixed platform, and a knob is fixedly connected to one end of the lead screw.

[0008] Optionally, the adjustment assembly further includes a fixing bolt, and the inner wall of the support column groove is provided with a threaded hole. The fixing bolt is threaded into the threaded hole and is used to fix the lead screw.

[0009] Optionally, a slide rail is provided on the inner wall of the fixing hole of the fixing platform, the fixing clamp is slidably connected in the slide rail, and a fixing spring is fixedly connected to one side of the fixing clamp, the fixing spring being fixedly connected to the inner wall of the slide rail.

[0010] Optionally, the outer casing is provided with an adjustment groove, a support rod is slidably connected in the adjustment groove, the drain head is fixedly connected to the support rod, a hydraulic rod is fixedly connected to the outer casing, and the support rod is fixedly connected to the movable end of the hydraulic rod.

[0011] According to one embodiment of this disclosure, when the operator is sorting pesticide residue test samples, first, the test tube is fixed in the fixing hole of the fixing platform. Then, the drive motor is started to make the dial drive the groove wheel to rotate. When the test tube rotates to the drain head, the electric valve opens to sort the sample into the test tube. At the same time, the operator can place another set of test tubes in other fixing holes of the fixing platform. After the sample sorting is completed, the dial rotates one more revolution to move another set of test tubes to the drain head for sorting. At the same time, the operator fixes another set of test tubes. Repeating the above operation can quickly sort the samples and speed up the sorting rate. At the same time, by controlling the speed of the drive motor and the opening time of the electric valve, the amount of sample sorted can be controlled, thereby improving the accuracy of the detection structure.

[0012] This invention features an adjustment mechanism. By loosening the fixing bolts and then rotating the knob to rotate the lead screw, the fixing platform slides within the groove of the support column under the threaded engagement of the lead screw. This changes the distance between the fixing platform and the support platform, allowing the device to accommodate test tubes of different heights. This prevents test tubes that are too short to be fixed in the fixing holes of the support and fixing platforms. Simultaneously, by controlling the extension and retraction of the hydraulic rod, the support rod slides within the adjustment groove of the outer shell, thereby adjusting the height of the support rod, which in turn adjusts the height of the drain head. This, in turn, changes the distance between the drain head and the test tube, allowing the device to accommodate test tubes of different heights and preventing sample leakage caused by the drain head being too far from the test tube.

[0013] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0017] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0018] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0019] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0020] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0021] like Figure 1-6 As shown, a pesticide residue detection sample separation device includes a shell 1, which is made of stainless steel. The main function of the shell 1 is to support the entire device and ensure that the device remains stable during operation.

[0022] Furthermore, a groove is provided on the outer shell 1, and a support platform 2 is rotatably connected in the groove. A drive assembly 3 is provided inside the outer shell 1, which is used to drive the support platform 2 to rotate.

[0023] Specifically, the drive assembly 3 includes a drive motor 31, which is fixedly connected inside the housing 1, and a dial 32 is fixedly connected to the output end of the drive motor 31.

[0024] Furthermore, a rotating shaft 33 is fixedly connected to the fixed platform 5. The rotating shaft 33 is rotatably connected to the outer casing 1. A grooved wheel 34 is fixedly connected to the rotating shaft 33, and the grooved wheel 34 meshes with the dial 32.

[0025] Specifically, by starting the drive motor 31, the dial 32 is driven to rotate. After the dial 32 rotates, the grooved wheel 34 rotates intermittently. After the grooved wheel 34 rotates, the rotating shaft 33 rotates, thereby driving the support platform 2 and the fixed platform 5 to rotate. This causes the test tube on the support platform 2 to rotate. At the same time, the groove spacing of the grooved wheel 34 in this application is sixty degrees, and the fixing hole of the fixed platform 5 corresponds to it. Therefore, when the dial 32 rotates one revolution, the grooved wheel 34 rotates sixty degrees, and the fixing hole on the fixed platform 5 moves one position accordingly.

[0026] More specifically, when the operator is sorting pesticide residue test samples, they first fix the test tubes in the fixing holes of the fixing platform 5, then start the drive motor 31 to make the dial 32 drive the groove wheel 34 to rotate. When the test tube rotates to the drain head 10, the electric valve 11 opens to sort the sample into the test tube. At the same time, the operator can place another set of test tubes in other fixing holes of the fixing platform 5. After the sample sorting is completed, the dial 32 rotates one more turn to move another set of test tubes to the drain head 10 for sorting. At the same time, the operator fixes another set of test tubes. Repeating the above operation can quickly sort the samples and speed up the sorting rate. At the same time, by controlling the speed of the drive motor 31 and the opening time of the electric valve 11, the amount of sample sorted can be controlled, improving the accuracy of the detection structure.

[0027] Furthermore, a support column 4 is fixedly connected to the support platform 2, a fixed platform 5 is movably connected to the support column 4, an adjustment component 6 is provided on the support column 4, the adjustment component 6 includes a lead screw 61, a sliding groove is provided on the support column 4, the fixed platform 5 is slidably connected in the sliding groove, the lead screw 61 is rotatably connected in the sliding groove, the lead screw 61 is threadedly connected to the fixed platform 5, and a knob 62 is fixedly connected to one end of the lead screw 61.

[0028] Furthermore, the adjusting assembly 6 also includes a fixing bolt 63. The inner wall of the slide groove of the support column 4 is provided with a threaded hole, and the fixing bolt 63 is threaded into the threaded hole. The fixing bolt 63 is used to fix the lead screw 61.

[0029] Specifically, by loosening the fixing bolt 63, and then turning the knob 62 to drive the lead screw 61 to rotate, the fixing platform 5 will slide in the groove of the support column 4 under the thread engagement with the lead screw 61, thereby changing the distance between the fixing platform 5 and the support platform 2, so that the device can adapt to test tubes of different heights and avoid the test tubes being too short to be fixed in the fixing holes of the support platform 2 and the fixing platform 5.

[0030] Furthermore, the fixing platform 5 has multiple sets of fixing holes, and fixing clips 7 are movably connected in the fixing holes. The inner wall of the fixing holes of the fixing platform 5 is provided with a slide rail, and the fixing clips 7 are slidably connected in the slide rail. A fixing spring 12 is fixedly connected to one side of the fixing clips 7, and the fixing spring 12 is fixedly connected to the inner wall of the slide rail.

[0031] Specifically, when fixing the test tube, the test tube is inserted into the fixing hole of the fixing platform 5. The fixing clamp 7 in the fixing hole will automatically fix the test tube and center it due to the elastic force of the fixing spring 12, thereby avoiding deviation between the drain head 10 and the test tube, which would cause sample leakage.

[0032] Furthermore, a liquid storage cylinder 8 is fixedly connected inside the outer shell 1. One end of the liquid storage cylinder 8 is fixedly connected to an injection pipe 13, and the other end of the liquid storage cylinder 8 is fixedly connected to a drain pipe 9. One end of the drain pipe 9 is fixedly connected to a drain head 10, which is movably connected to the outer shell 1. An electric valve 11 is fixedly connected to the drain head 10. By controlling the opening and closing of the electric valve 11, the drain head 10 can be controlled to discharge the sample.

[0033] Furthermore, an adjustment groove is provided on the outer casing 1, and a support rod 14 is slidably connected in the adjustment groove. The drain head 10 is fixedly connected to the support rod 14, and a hydraulic rod 15 is fixedly connected to the outer casing 1. The support rod 14 is fixedly connected to the movable end of the hydraulic rod 15.

[0034] Specifically, by controlling the extension and retraction of the hydraulic rod 15, the support rod 14 slides in the adjustment groove of the outer shell 1, thereby adjusting the height of the support rod 14, which is to say, adjusting the height of the drain head 10, thereby changing the distance between the drain head 10 and the test tube, so that the device can adapt to test tubes of different heights and avoid sample leakage caused by the drain head 10 being too far away from the test tube.

[0035] In the above-mentioned pesticide residue detection sample separation device, when the operator separates the pesticide residue detection samples, first fixes the test tube in the fixing hole of the fixing platform 5, then starts the drive motor 31 to make the dial 32 drive the groove wheel 34 to rotate. When the test tube rotates to the drain head 10, the electric valve 11 opens to separate the sample into the test tube. At the same time, the operator can place another set of test tubes in other fixing holes of the fixing platform 5. After the sample separation is completed, the dial 32 rotates one more turn to move another set of test tubes to the drain head 10 for separation. At the same time, the operator fixes another set of test tubes. Repeating the above operation can quickly separate the samples and speed up the separation rate. At the same time, by controlling the speed of the drive motor 31 and the opening time of the electric valve 11, the amount of sample separation can be controlled, thereby improving the accuracy of the detection structure.

[0036] This utility model is equipped with an adjustment component 6. By loosening the fixing bolt 63 and then rotating the knob 62 to drive the lead screw 61 to rotate, the fixing platform 5 will slide in the groove of the support column 4 under the thread engagement with the lead screw 61, thereby changing the distance between the fixing platform 5 and the support platform 2. This allows the device to adapt to test tubes of different heights, avoiding test tubes that are too short to be fixed in the fixing holes of the support platform 2 and the fixing platform 5. At the same time, by controlling the extension and retraction of the hydraulic rod 15, the support rod 14 slides in the adjustment groove of the outer shell 1, thereby adjusting the height of the support rod 14, that is, adjusting the height of the drain head 10, and thus changing the distance between the drain head 10 and the test tube. This allows the device to adapt to test tubes of different heights and avoids sample leakage caused by the drain head 10 being too far away from the test tube.
