Technical Field
[0001] This utility model relates to the field of pesticide residue detection technology, and in particular to a pesticide residue detection device. Background Technology
[0002] Pesticides are chemically synthesized substances or mixtures of substances derived from organisms, other natural products, or produced by the application of biotechnology, used to prevent, eliminate, or control diseases, insects, weeds, and other harmful organisms that endanger agriculture and forestry, as well as to purposefully regulate, control, and influence the metabolism, growth, development, and reproduction processes of plants and harmful organisms. In agricultural production, pesticides can protect and promote the growth of plants and crops, and have the functions of killing insects, fungi, and harmful animals (or weeds).
[0003] After pesticide research and development is completed, it is essential to ensure that the pesticide residue test results are qualified before it can be put into use. However, in the process of pesticide residue testing, it is necessary to randomly sample the fruits grown with pesticides, remove the tissue from the sample and place it in a test tube, add reagents and stir, and then measure it through a testing instrument. The whole process is mostly manual. However, the test tube holder of the existing testing instrument has drawbacks. It is difficult to stably hold test tubes of different diameters, which makes it easy for the test tubes to tip over during the testing process, affecting the accuracy of the test results. Therefore, a pesticide residue testing device is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a pesticide residue detection device to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pesticide residue detection device includes a base plate, a placement box fixedly installed on the top side of the base plate, elongated holes on both sides of the placement box, a fixing plate fixedly installed inside the placement box, a fixing clamp fixedly installed on one side of multiple fixing plates, multiple movable plates arranged inside the placement box, movable clamps fixedly installed on the side of multiple movable plates facing the fixing plate, protective pads arranged inside the multiple fixing clamps and multiple movable clamps, a fixing frame fixedly installed on the top side of the base plate, a drive assembly arranged on one side of the fixing frame, a support above the fixing frame, and a stirring assembly arranged below the support.
[0007] Preferably, the drive assembly includes a first electric push rod fixedly mounted on one side of a fixed frame, the output end of the first electric push rod passing through the fixed frame and fixedly connected to a connecting plate, the connecting plate being L-shaped.
[0008] Preferably, a connecting rod is fixedly installed on one side of each of the multiple movable plates, and the other side of each of the multiple connecting rods is fixedly connected to one side of the connecting plate. The multiple connecting rods slide within an elongated hole in the placement box, and a guide rod is fixedly installed within another elongated hole in the placement box. Multiple guide blocks are slidably sleeved on the outer side of the guide rods, and the other side of each of the multiple guide blocks is fixedly connected to one side of each of the multiple movable plates.
[0009] Preferably, the stirring assembly includes a third electric push rod fixedly mounted on the top side of the support, the output end of the third electric push rod passing through the support and fixedly connected to the mounting frame, multiple motors fixedly mounted on the bottom inner wall of the mounting frame, the output ends of the multiple motors rotating through the mounting frame, and multiple stirring rods fixedly connected to the outer sides of the output ends of the multiple motors.
[0010] Preferably, a second electric push rod is fixedly installed on one side of the fixed frame. The output end of the second electric push rod passes through the fixed frame and is fixedly connected to one side of the bracket. A guide groove is provided on the bottom inner wall of the fixed frame. A limit plate is slidably installed in the guide groove. The top side of the limit plate is fixedly connected to the bottom side of the bracket.
[0011] Preferably, multiple sponge pads are fixedly installed on the bottom inner wall of the placement box, and the multiple sponge pads are respectively located between multiple fixed clamps and multiple movable clamps, with test tubes arranged between the multiple fixed clamps and multiple movable clamps.
[0012] Preferably, a detector is fixedly installed on the top side of the base plate, and the detector is located on one side of the placement box.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The fixed and movable clamps inside the box are adjusted in distance by the first electric push rod, which can firmly clamp test tubes of different sizes. When a batch of smaller test tubes are placed in, the second electric push rod drives the support to move to the left, so that the stirring rod is aligned with the center of the test tube, preventing the stirring rod from shifting when it moves down. Multiple guide blocks are slidably sleeved on the guide rod, providing guidance and limiting for the displacement of the movable plate. This ensures that the test tubes can be stably clamped during the testing process, ensuring smooth stirring, improving testing efficiency and accuracy, and meeting the testing needs of test tubes of different sizes.
[0015] 2. The included sponge pads and protective pads effectively protect the test tubes. The sponge pads prevent the bottom of the test tubes from contacting the inner wall of the placement box, reducing collision and friction damage and extending the lifespan of the test tubes. Multiple test tubes can be used to test multiple tissues simultaneously, improving the testing speed. The third electric push rod moves the mounting bracket downwards, and the motor drives the stirring rod to mix the tissues and reagents in the test tubes, enabling parallel operation without interference. This improves testing efficiency and ensures the accuracy of test results, providing strong support for large-scale testing. Attached Figure Description

[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. 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.
[0022] Reference Figure 1-4A pesticide residue detection device includes a base plate 1, a placement box 2 fixedly installed on the top side of the base plate 1, elongated holes on both sides of the placement box 2, a fixing plate 3 fixedly installed inside the placement box 2, fixing clamps 4 fixedly installed on one side of each fixing plate 3, multiple movable plates 5 disposed inside the placement box 2, movable clamps 6 fixedly installed on the side of each movable plate 5 facing the fixing plate 3, protective pads 7 disposed inside each of the multiple fixing clamps 4 and multiple movable clamps 6, a fixing frame 12 fixedly installed on the top side of the base plate 1, a drive assembly disposed on one side of the fixing frame 12, and a [missing information - likely a device name or structure] disposed above the fixing frame 12. A support 15 is provided, and a stirring assembly is provided below the support 15. The driving assembly includes a first electric push rod 13 fixedly installed on one side of a fixed frame 12. The output end of the first electric push rod 13 passes through the fixed frame 12 and is fixedly connected to a connecting plate 9. The connecting plate 9 is L-shaped. A connecting rod 8 is fixedly installed on one side of each of the multiple movable plates 5. The other side of each of the multiple connecting rods 8 is fixedly connected to one side of the connecting plate 9. The multiple connecting rods 8 slide in one elongated hole of the placement box 2. A guide rod 10 is fixedly installed in another elongated hole of the placement box 2. Multiple guide blocks 11 are slidably sleeved on the outside of the guide rod 10. The other side of each of the multiple guide blocks 11 is fixedly connected to one side of each of the multiple movable plates 5. A first electric push rod 13 is provided. Before fixing the multiple test tubes 23, the multiple test tubes 23 are placed sequentially on the sponge pad 22. After placement, the first electric push rod 13 is activated, causing the connecting plate 9 to move backward. During this process, the connecting plate 9 synchronously moves the multiple connecting rods 8. Since the multiple connecting rods 8 are fixedly connected to one side of each of the multiple movable plates 5, the multiple movable plates 5 also move synchronously with the connecting rods 8. When the multiple movable plates 5 move backward, they interact with the multiple fixed... The fixed clamping plates 4 are installed in a fixed manner to securely hold multiple test tubes 23. The distance between the fixed clamping plates 4 and the multiple movable clamping plates 6 is adjusted by the first electric push rod 13. This allows the device to hold a batch of test tubes 23 of the same size. When facing another batch of test tubes 23 of different sizes, whether larger or smaller, it can be flexibly adjusted. Furthermore, by providing multiple guide blocks 11, which are slidably sleeved on the guide rod 10, the device can guide and limit the movement of the multiple movable plates 5.
[0023] Specifically, the stirring assembly includes a third electric actuator 16 fixedly mounted on the top side of the support 15. The output end of the third electric actuator 16 passes through the support 15 and is fixedly connected to a mounting frame 17. Multiple motors 18 are fixedly mounted on the bottom inner wall of the mounting frame 17. The output ends of the multiple motors 18 all rotate through the mounting frame 17. Multiple stirring rods 19 are fixedly connected to the outer sides of the output ends of the multiple motors 18. By setting multiple sets of stirring rods 19, after the multiple test tubes 23 are clamped and stabilized, reagents are poured into the test tubes 23 in sequence. Then, the third electric actuator 16 is started, and the operation of the third electric actuator 16 drives the mounting frame 17. The frame 17 moves downward, allowing multiple sets of stirring rods 19 to extend into multiple test tubes 23. When the bottom of the mounting frame 17 contacts the top side of the test tube 23, multiple motors 18 are started simultaneously, thereby driving the multiple sets of stirring rods 19 to mix and stir the tissues and reagents in the test tubes 23. This enables the simultaneous detection of multiple fruit tissues, greatly improving detection efficiency. During the detection process, in order to ensure the accuracy of the detection results, the stirring speed, time, and other parameters of the multiple motors 18 can be optimized to cope with the fact that different tissues may require different stirring speeds and times to ensure thorough mixing.
[0024] Specifically, a second electric push rod 14 is fixedly installed on one side of the fixed frame 12. The output end of the second electric push rod 14 passes through the fixed frame 12 and is fixedly connected to one side of the bracket 15. A guide groove is provided on the bottom inner wall of the fixed frame 12. A limit plate 20 is slidably installed in the guide groove. The top side of the limit plate 20 is fixedly connected to the bottom side of the bracket 15. By setting the second electric push rod 14, when replacing a batch of smaller test tubes 23 for clamping, since the multiple sets of stirring rods 19 are still in the position of the previous batch of test tubes 23, the second electric push rod 14 is started. It drives the bracket 15 to move to the left, so that the multiple sets of stirring rods 19 can be aligned with the center position of this batch of test tubes 23. In this way, the multiple sets of stirring rods 19 can avoid the situation of the multiple sets of stirring rods 19 shifting when moving downward. In addition, by setting the limit plate 20, the limit plate 20 can play a supporting and guiding role when moving between, so that it can move smoothly.
[0025] Specifically, multiple sponge pads 22 are fixedly installed on the inner wall of the bottom side of the placement box 2. The multiple sponge pads 22 are respectively located between multiple fixed clamps 4 and multiple movable clamps 6. Test tubes 23 are arranged between the multiple fixed clamps 4 and multiple movable clamps 6. A detector 21 is fixedly installed on the top side of the base plate 1. The detector 21 is located on one side of the placement box 2. By setting multiple sponge pads 22, the bottom of the test tubes 23 can be prevented from contacting the inner wall of the bottom side of the placement box 2 and being damaged. The sponge pads 22 not only provide a cushioning effect, but also reduce the damage to the test tubes 23 caused by collisions and friction, and extend the service life of the test tubes 23. By setting multiple test tubes 23, multiple test tubes 23 can simultaneously detect multiple tissues, thereby greatly improving the detection speed. Different tissues can be placed in different test tubes 23 at the same time and detected simultaneously. In this way, more samples can be processed per unit time, meeting the needs of large-scale detection. Moreover, multiple test tubes 23 can operate in parallel without interfering with each other, further improving detection efficiency.
[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
[0027] In use: A portion of tissue from different fruits is placed in test tube 23. Multiple test tubes 23 are then placed sequentially on sponge pad 22. After placement, the first electric push rod 13 is activated, causing the connecting plate 9 to move backward. As the connecting plate 9 moves backward, it simultaneously moves multiple connecting rods 8. Because the multiple connecting rods 8 are fixedly connected to one side of multiple movable plates 5, the multiple movable plates 5 also move synchronously with the connecting rods 8. During the backward movement of the multiple movable plates 5, in conjunction with the multiple fixed clamping plates 4, the multiple test tubes 23 are securely clamped. Since the distance between the multiple fixed clamping plates 4 and the multiple movable clamping plates 6 is adjusted by the first electric push rod 13, a batch of test tubes 23 of the same size can be clamped. Furthermore, when clamping another batch of test tubes 23 of different sizes, the distance can be freely adjusted. The multiple protective pads 7 prevent damage to the test tubes 23 during clamping. After the test tubes 23 are stably clamped, the reagents are poured into them sequentially, which activates the third electric push rod 16. The third electric push rod 16 moves the mounting frame 17 downward, allowing multiple stirring rods 19 to extend into the test tubes 23. When the bottom of the mounting frame 17 contacts the top of the test tubes 23, multiple motors 18 are activated simultaneously, driving the stirring rods 19 to mix the tissues and reagents in the test tubes 23. This allows for simultaneous testing of multiple fruit tissues, thus accelerating the testing efficiency and improving the accuracy of the results. After the testing is completed, the third electric push rod 16 moves the mounting frame 17 upward again, and the detector 21 can then sequentially test the tissues in the test tubes 23.
