Description

[0002] The development of agricultural industrialization has made the production of agricultural products increasingly dependent on exogenous substances such as pesticides, antibiotics and hormones. The use of veterinary drugs and pesticides in agricultural products continues to remain high. The irrational use of these substances will inevitably lead to excessive drug residues in agricultural products, affecting consumer food safety. In severe cases, it will cause consumers to become ill, develop abnormally, or even directly lead to poisoning and death. Therefore, it is necessary to detect drug residues in crops. In the existing technology, when testing for drug residues in crops, the test mixture needs to be shaken and mixed before being placed in the detection instrument for testing.
[0003] The treated sample is mixed with the solvent and fully mixed through mechanical vibration.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an agricultural product drug residue detection oscillation device, including a detection box 1, a placement box 2 is provided inside the detection box 1, a fixed component is provided inside the placement box 2, a fixed frame 3 is fixedly connected to the detection box 1, and an oscillation component is provided inside the fixed frame 3; the oscillation component includes a slide plate 4, the upper surface of the slide plate 4 is fixedly connected to the bottom of the placement box 2, the side wall of the slide plate 4 is slidably connected to the inside of the fixed frame 3, the side wall of the fixed frame 3 is rotatably connected to an elliptical plate 5, and the elliptical plate 5 is used to drive the overall shaking, the bottom of the placement box 2 is fixedly connected to a fixed plate 6, the side wall of the fixed plate 6 is slidably connected to the inside of the fixed frame 3, the side wall of the fixed plate 6 is rotatably connected to a connecting rod 7, the side wall of the connecting rod 7 is rotatably connected to the side wall of the elliptical plate 5, the inside of the fixed frame 3 is fixedly connected to a round rod 8, and the fixed plate 6 is slidably connected to the inside of the fixed frame Connected to the side wall of the round rod 8, the side wall of the round rod 8 is sleeved with a first spring 9, the first spring 9 is used for rebound reset, the side wall of the fixed frame 3 is provided with a motor 10, the output end of the motor 10 is connected to the elliptical plate 5, the side wall of the placement box 2 is fixedly connected with a fixing rod 11, the fixing rod 11 makes the placement box 2 shake more smoothly, a connecting plate 12 is provided inside the detection box 1, and a second spring 13 is provided inside the detection box 1, the second spring 13 is used for rebound reset, one end of the first spring 9 is fixedly connected to the inside of the fixed frame 3, the other end of the first spring 9 is fixedly connected to the side wall of the fixing plate 6, the side wall of the connecting plate 12 is fixedly connected to the side wall of the fixing rod 11, the fixing rod 11 is slidably connected to the inside of the detection box 1, one end of the second spring 13 is fixedly connected to the side wall of the connecting plate 12, and the other end of the second spring 13 is fixedly connected to the inside of the detection box 1;
[0034] In order to fully mix and extract the sample and ensure that the drug residue components in the sample are evenly distributed, the start of the motor 10 causes the elliptical plate 5 to start rotating, and the rotation of the elliptical plate 5 drives the connecting rod 7 to rotate together. The rotation of the connecting rod 7 causes the fixed plate 6 to slide on the side wall of the round rod 8, so that the first spring 9 is subjected to pressure to compress and stretch, and at the same time, the slide plate 4 slides inside the fixed frame 3. The slide plate 4 and the fixed plate 6 drive the placement box 2 to shake. The shaking of the placement box 2 causes the fixed rod 11 to slide inside the detection box 1. The movement of the fixed rod 11 pushes the connecting plate 12 to move inside the detection box 1. The movement of the connecting plate 12 causes the second spring 13 to be squeezed and compressed and stretched. The movement of the fixed rod 11 makes the shaking of the placement box 2 more stable. As the placement box 2 vibrates, the cell structure of the sample in the test tube is destroyed, and the drug residues are released from the cells into the solvent to form a uniform mixed solution.
[0035] Reference Figure 4 and Figure 5 The fixing component includes a sleeve 15, a placement slot 14 is opened inside the placement box 2, the placement slot 14 is used to place the test tube, the sleeve 15 is fixedly connected to the inside of the placement box 2, and a slider 16 is slidably connected inside the sleeve 15. The side wall of the slider 16 is fixedly connected to a fixed block 17, and the side wall of the fixed block 17 is fixedly connected to a splint 18. The side wall of the splint 18 is fixedly connected to a rubber pad 19. The rubber pad 19 is used to increase friction and prevent test tube wear. The side wall of the fixed block 17 is fixedly connected to an elastic band 20. A third spring 21 is provided inside the sleeve 15. The third spring 21 is used for rebound reset. One end of the third spring 21 is fixedly connected to the inside of the sleeve 15, and the other end of the third spring 21 is fixedly connected to the side wall of the slider 16;
[0036] After the sample to be tested is processed into a suitable state, the test tube is inserted into the placement slot 14. During the insertion of the test tube, the splint 18 will be squeezed to move it. The movement of the splint 18 causes the fixed block 17 to squeeze the slider 16. The slider 16 enters the sleeve 15 as it is squeezed. The movement of the slider 16 pressurizes the third spring 21 to cause it to deform. At the same time, as the test tube continues to move, the elastic band 20 fixed to the side wall of the splint 18 is stretched and deformed. When the test tube is inserted into the appropriate position and stops moving, the third spring 21 and the elastic band 20 are reset. The force generated by them will cause the splint 18 to restrict the test tube and fix it. At the same time, a rubber pad 19 is fixed to the side wall of the splint 18. The rubber pad 19 can prevent the splint 18 from being worn when the test tube moves and is fixed to it, and also increase the friction to make it more stable.
[0037] Working principle: In order to fully mix and extract the sample and ensure that the drug residues in the sample are evenly distributed, start the motor 10 to rotate the elliptical plate 5. The rotation of the elliptical plate 5 drives the connecting rod 7 to rotate. The rotation of the connecting rod 7 causes the fixed plate 6 to slide on the side wall of the round rod 8, so that the first spring 9 is compressed and stretched by pressure. At the same time, the shaking of the placement box 2 causes the fixed rod 11 to slide inside the detection box 1, squeezing the connecting plate 12, so that the second spring 13 is compressed and stretched by pressure, making the shaking of the placement box 2 more stable. The placement box 2 vibrates, so that the cell structure of the sample in the test tube is destroyed, and the drug residues are released from the cells into the solvent to form a uniform mixed liquid.
[0038] After the sample to be tested is processed into a suitable state, the test tube is inserted into the placement groove 14. The entry of the test tube causes the splint 18 to be squeezed and moved. The movement of the splint 18 causes the slider 16 to enter the sleeve 15, squeezing the third spring 21 to shrink it. At the same time, as the splint 18 moves, the elastic band 20 is stretched and deformed. When the test tube is inserted into the appropriate position, it stops moving. The third spring 21 and the elastic band 20 are reset. The force generated by them will limit the test tube and fix it. At the same time, a rubber pad 19 is fixed to the side wall of the splint 18. The rubber pad 19 prevents the splint 18 from being worn when the test tube moves and is fixed to it, and also increases the friction to make it more stable.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
