Description
Technical Field
[0001] The present invention relates to the technical field of detection devices, in particular to a pesticide residue detection device used in food engineering. Background Art
[0002] With the continuous development of modern agricultural production methods, pesticides have been widely used in agricultural production as an important means to ensure crop yield and quality. However, during use, pesticide residues inevitably form on or within agricultural products. Long-term consumption of foods containing pesticide residues can pose potential health risks, such as affecting the nervous and endocrine systems and even inducing cancer. Therefore, the development of efficient, accurate, and rapid pesticide residue detection methods and devices is of great significance for ensuring food safety and protecting consumer rights.
[0003] The use of existing pesticide residue detection devices presents several practical problems that affect detection accuracy. First, many devices lack precise quantitative control when adding water samples, resulting in inconsistent sample amounts and an inability to effectively compare the sample with the test solution, thus affecting the accuracy of the final test results. Furthermore, during the test process, some drugs tend to adhere to the inner wall of the container, causing the detected results to be inconsistent with the actual results and making it difficult to thoroughly clean them. These residues may interfere with the next test, causing the measured data to deviate from the true value and affecting the reliability of the test. Based on this, the present invention designs a pesticide residue detection device for food engineering to address the above-mentioned problems. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0033] See also Figure 1-8 , the present invention provides a technical solution:
[0034] A pesticide residue detection device for food engineering includes a detection box 1, a quantitative mechanism and a rotating mechanism. The quantitative mechanism includes an electric telescopic rod 71, an expansion rod 72 is installed at the output shaft end of the electric telescopic rod 71, and a stopper 43 is installed at the bottom of the expansion rod 72. A first circular baffle 73 is provided with a plurality of first through grooves 74 inside, and a plurality of first circular filling plates 75 are symmetrically installed at the bottom of the first circular baffle 73. A movable rod 76 is symmetrically installed inside the first circular baffle 73, and a second circular baffle 77 is installed at the bottom of the movable rod 76. A second through groove 78 used in conjunction with the first circular filling plate 75 is provided inside the second circular baffle 77, and a second circular filling plate 79 used in conjunction with the first through groove 74 is installed on the top of the second circular baffle 77; the cooperation of the first through groove 74 and the second circular filling plate 79 stops the detection box 1 from being injected with water, so as to avoid the inconsistency of the amount of sample added due to the difficulty in quantitatively measuring the water added to the detection box 1, and the inability to effectively compare with the detection liquid, thereby affecting the accuracy of the final detection result.
[0035] The rotating mechanism includes a servo motor 51, with a rotating rod 52 mounted on the end of the output shaft of the servo motor 51. A first fixing ring 53 is fixedly mounted on the outside of the rotating rod 52, and a first L-shaped cleaning rod 54 is fixedly mounted on the outside of the first fixing ring 53. A second fixing ring 55 is mounted on the outside of the rotating rod 52 below the first fixing ring 53, and a second L-shaped cleaning rod 56 is fixedly mounted on the outside of the second fixing ring 55. The first L-shaped cleaning rod 54 and the second L-shaped cleaning rod 56 are used in conjunction with each other to clean pesticides adhered to the inner wall of the test box 1, preventing the pesticides from adhering to the inner wall of the test box 1, resulting in incomplete fusion with the test liquid and inaccurate test results.
[0036] A holder 57 is installed inside the test box 1. Several first stirring blades 58 and several second stirring blades 59 are symmetrically mounted on the outside of the rotating rod 52. The rotating rod 52 drives the first and second stirring blades 58 and 59 to stir the water inside the test box 1. A water inlet 21 is installed at the top of the test box 1, and a support rod 22 is installed outside the water inlet 21. A water pipe is connected to the water inlet 21 to add an appropriate amount of water to the interior of the test box 1.
[0037] A support plate 23 is mounted on top of the support rod 22, and a limit cylinder 24 is installed inside the detection box 1. An electric telescopic rod 71 is mounted on top of the support plate 23. A controller 31 is mounted on the outside of the detection box 1, and a protective plate 32 is installed inside the detection box 1. The material of the protective plate 32 is sintered metal mesh.
[0038] The top of the testing box 1 is equipped with a placement tube 6. Workers place vegetables into this placement tube 6 for testing. The placement tube 6 is made of porous stainless steel. Several support columns 41 are symmetrically mounted on the bottom of the testing box 1. Each support column 41 is equipped with a return spring 42, and each return spring 42 has a stopper 43 installed at its base. The return springs 42 and stopper 43 work together to dissipate stress generated during movement.
[0039] Bearings 44 are mounted at the bottom of each block 43, and an iron block 45 is mounted at the bottom of each bearing 44. Universal wheels 47 are rotated by means of block 43. Connecting rods 46 are mounted on both sides of iron block 45, and universal wheels 47 are mounted on the outside of connecting rods 46. The operator uses the coordinated use of several universal wheels 47 to move the test box 1.
[0040] When food needs to be tested for pesticide residues, the staff needs to move the test box 1. The staff moves the test box 1 by using a number of universal wheels 47. During the movement, the stress generated during the movement can be eliminated by using the return spring 42 and the block 43, avoiding damage to the device caused by the stress generated during the movement due to difficulty in eliminating the stress. After moving to the appropriate position, the staff stops moving and controls the device to work through the controller 31.
[0041] When the water in the test box 1 reaches the desired position, the staff member stops filling the test box 1 with water, and starts the electric telescopic rod 71. The electric telescopic rod 71 drives the expansion rod 72 to move up and down. During the lifting process, the expansion rod 72 drives the first circular baffle 73 to move up and down. After the first circular baffle 73 is lifted to the appropriate position, the electric telescopic rod 71 is closed. At this time, the water pipe is connected to the water inlet 21. The water inside the water pipe enters the water inlet 21 through the water inlet 21 and enters the test box 1 through the first through-groove 74 and the second through-groove 78. When the water inside the test box 1 reaches the moving height, the second circular baffle 77 is suspended by the water. When the water inside the test box 1 reaches the appropriate position, the first through-groove 74 and the second circular filling plate 79 are used in conjunction with each other to stop filling the test box 1 with water, so as to avoid the inconsistency of the amount of sample added due to the difficulty in quantifying the water added to the test box 1, and the inability to effectively compare with the test liquid, thereby affecting the accuracy of the final test result.
[0042] After adding an appropriate amount of water to the inside of the test box 1, the servo motor 51 is started. The servo motor 51 drives the rotating rod 52 to rotate. During the rotation process, the rotating rod 52 drives the first fixed ring 53 and the second fixed ring 55 to rotate. During the rotation process, the first fixed ring 53 and the second fixed ring 55 drive the first L-shaped cleaning rod 54 and the second L-shaped cleaning rod 56 to rotate. During the rotation process, the first L-shaped cleaning rod 54 and the second L-shaped cleaning rod 56 clean the pesticides attached to the inner wall of the test box 1 to prevent the pesticides from adhering to the inner wall of the test box 1, resulting in incomplete fusion with the test liquid and inaccurate final test results. During the rotation process, the rotating rod 52 drives the first stirring blade 58 and the second stirring blade 59 to stir the water inside the test box 1.
