[0024] 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.

[0025] Please see Figure 1-7 This utility model provides a technical solution: a pesticide residue detection device, including a base plate 1, a fixed seat 2 fixedly installed on the top of the base plate 1, a frame 3 fixedly installed on the top of the fixed seat 2, a lifting component 4 extending to the outside of the fixed seat 2, an installation component 7 extending to the inside of the frame 3, a detection component 8 extending to the bottom of the installation component 7, and a support base 9 fixedly installed at the bottom of the base plate 1 to enhance the stability of the device and prevent it from tipping over due to vibration or external force during the detection process.

The left and right sides of the threaded cylinder 47 are fixedly installed with limiting rods 49 that are slidably connected to the two limiting frames 48, respectively. After the servo motor 45 is started, it drives the threaded rod 46 to rotate. The threaded cylinder 47 is threadedly engaged with the threaded rod 46 and slidably connected to the limiting frame 48 through the limiting rods 49, converting the rotational motion into linear motion, driving the moving frame 42 to rise and fall vertically along the mounting hole 41. The support plates 44 on both sides of the moving frame 42 contact the fixed plate 43 to form a double support structure, preventing deviation or shaking during the lifting process, and ensuring that the tray 53 and the sample container are accurately positioned below the detection head 87, so as to facilitate the adjustment of the height of the sample to be tested as needed.

[0027] The support mechanism 5 includes a box body 51. The box body 51 is fixedly installed on the top left and right ends of the movable frame 42. A connecting plate 52 extending to the outside of the box body 51 is slidably installed on the inner side of the box body 51. A support plate 53 is fixedly installed between the two connecting plates 52. A limit seat 54 is fixedly installed on the top of the support plate 53. A connecting column 55 located on the front and rear sides of the limit seat 54 is fixedly installed on the top of the support plate 53. A top frame 56 is fixedly installed between the front and rear connecting columns 55. Vertical plates 57 are fixedly installed on the upper and lower sides of the connecting plate 52 located on the inner side of the box body 51. A support rod 58 penetrating the vertical plate 57 is fixedly installed between the left and right sides of the inner wall of the box body 51. A telescopic spring 59 fixedly connected to the inner wall of the box body 51 and sleeved on the outside of the support rod 58 is fixedly installed on one side of the top vertical plate 57.

[0029] Mounting assembly 7 includes an electric push rod 71, which is fixedly mounted on the top of the frame 3. The output end of the electric push rod 71 extends into the inner side of the frame 3, and a rectangular frame 72 is fixedly mounted on the output end of the electric push rod 71.

[0030] The detection component 8 includes a circular hole 81. A circular hole 81 is formed in the inner bottom wall of a rectangular frame 72. Two U-shaped frames 82 are fixedly installed on the inner bottom wall of the rectangular frame 72, located on the left and right sides of the circular hole 81 respectively. Baffles 83, which are fixedly connected to the inner bottom wall of the rectangular frame 72, are fixedly installed on opposite sides of the left and right U-shaped frames 82. A return spring 84 extending into the inner side of the rectangular frame 72 is fixedly installed on one side of the baffle 83. The elastic coefficient of the return spring 84 can be set according to requirements. A movable plate 85 extending to the top of the rectangular frame 72 is fixedly installed at one end of the return spring 84. A retaining ring 86 is fixedly installed at the bottom of the plate 85, which is slidably connected to the inner bottom wall of the rectangular frame 72 and extends to its outer side. A detection head 87 is movably installed between the two retaining rings 86, passing through the circular hole 81 and extending to the bottom of the rectangular frame 72. By pushing the moving plate 85, the return spring 84 is compressed, and the retaining ring 86 opens, allowing for quick installation or replacement of the detection head 87. After release, the return spring 84 pushes the moving plate 85 to reset, and the retaining ring 86 clamps the detection head 87. The six circular holes 81 correspond to the six detection heads 87, which can simultaneously detect multiple samples or different indicators of the same sample, greatly improving detection efficiency.

[0031] The inner top wall of the U-shaped frame 82 is provided with strip-shaped holes that are adapted to the moving trajectory of the moving plate 85, and there are six round holes 81.

[0032] When in use, connect the power supply and start the servo motor 45 to lower the tray 53 to the lowest position for easy placement of the sample container. Move the moving plate 85 to insert the detection head 87 into the round hole 81, ensuring that the bottom of the detection head contacts the liquid in the sample container. Release the moving plate 85 to fix the detection head with the retaining ring 86. Place the test tube containing the sample into the limiting seat 54 and the top frame 56 to ensure its stability. Set the detection height through the control panel. The servo motor 45 drives the moving frame 42 to rise, so that the tray 53 moves the sample container to accurately align with the detection head 87. Turn on the rotary motor 62, and the swing plate 63 drives the tray 53 to swing back and forth for 10-30 seconds to fully mix the sample and reagent. After mixing is complete, the rotary motor 62 stops, and the tray 53 returns to the horizontal position.

[0033] The electric push rod 71 pushes the rectangular frame 72 down, and the detection head 87 is immersed below the sample liquid surface, triggering the photoelectric sensor or spectrophotometer to start detection. The detection head 87 emits light of a specific wavelength to measure the absorbance or fluorescence intensity of the sample. The data is transmitted to the control system for analysis. The control system calculates the pesticide residue concentration according to a preset algorithm and displays the results on the screen or prints a report. After the detection is completed, the electric push rod 71 lifts the rectangular frame 72, the servo motor 45 lowers the support plate 53, the test tube is removed and the detection head 87 is cleaned, and the moving plate 85 is pushed to move and remove the detection head for maintenance.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] In summary, this pesticide residue detection device, through the setting of a support mechanism 5 and a drive mechanism 6, forms an enclosing structure with a limiting seat 54 and a top frame 56 to fix the sample container and prevent displacement during the detection process. Before detection, the drive mechanism 6 drives the support mechanism 5 to shake the sample, the rotary motor 62 drives the swing plate 63 to rotate, and the round rod 64 makes circular motion within the fixed frame 61. The left and right movement of the fixed frame 61 drives the tray 53 to swing back and forth. With the support of the connecting plate 52, the vertical plate 57 and the support rod 58, the stability of the movement of the tray 53 is ensured, simulating the effect of manual oscillation, so that the sample and reagent are fully mixed, improving the detection accuracy. It achieves the purpose of having a shaking structure to facilitate shaking the sample, and solves the problem that the fruit and vegetable samples to be tested still need to be shaken during the detection, but no corresponding shaking structure is set up, which affects the detection operation.
