The sample container 14 has an inner circular structure and an outer square structure. The inner circular cavity can facilitate the stirring of the blade 12, and the outer square structure can facilitate the limiting of the limiting frame 13, thereby avoiding rotation.

[0028] The sample container 14 is provided with a liquid inlet 15 and a liquid outlet 16. The liquid inlet 15 is located above the liquid outlet 16. The input end of the liquid inlet peristaltic pump 3 is communicated with the extraction liquid storage tank 2 through an extraction liquid input pipe 17. The output end of the liquid inlet peristaltic pump 3 is communicated with the liquid inlet 15 through an extraction liquid output pipe 18. The input end of the liquid outlet peristaltic pump 4 is communicated with the liquid outlet 16 through a sample input pipe 19. The output end of the liquid outlet peristaltic pump 4 is connected with a sample output pipe 20. The positioning seat 6 is provided with a clamping groove 22 matched with a gold mark detection card 21. When the gold mark detection card 21 is located in the clamping groove 22, the output end of the sample output pipe 20 faces the detection area of the gold mark detection card 21. The output end of the sample output pipe 20 is fixed through a fixing frame 27, so as to fix the position and direction of the output end of the sample output pipe 20.

[0029] The lifting frame 9 is fixed with an arc-shaped baffle 23, which is used to close the liquid outlet 16. When the linear actuator 8 drives the lifting frame 9 to descend, the arc-shaped baffle 23 descends to the inside of the sample container 14 and is attached to the inner wall of the sample container 14, so as to roughly close the liquid outlet 16.

[0030] The circular baffle 24 is rotatably installed on the rotating shaft 11 through a bearing. The circular baffle 24 is provided with a notch 25 matched with the arc-shaped baffle 23. The arc-shaped baffle 23 is clamped with the notch 25. The circular baffle 24 is used for sliding connection with the sample container 14, so as to prevent the circular baffle 24 from rotating with the rotating shaft 11.

[0031] The linear actuator 8 can drive the lifting frame 9 to move to the first height position, the second height position and the third height position, the heights of the first height position, the second height position and the third height position are lowered in turn; when the lifting frame 9 is at the first height position, the blade 12 is above the constant-temperature ultrasonic cleaner 5, and the distance between the blade 12 and the constant-temperature ultrasonic cleaner 5 is greater than the height of the sample container 14; when the lifting frame 9 is at the second height position, the circular baffle 24 is above the liquid inlet 15, and the arc-shaped baffle 23 closes the liquid outlet 16; when the lifting frame 9 is at the third height position, the circular baffle 24 is between the liquid inlet 15 and the liquid outlet 16, and the arc-shaped baffle 23 closes the liquid outlet 16.

[0032] The limiting frame 13 is embedded with a magnet 26, the top end of the magnet 26 is flush with the top end of the limiting frame 13, the top end of the sample container 14 is provided with a handle 27, the handle 27 is overlapped with the limiting frame 13, and the handle 27 is magnetically attracted to the magnet 26. Through the magnetic attraction between the handle 27 and the magnet 26, the sample container 14 can be prevented from being lifted by the friction when the circular baffle 24 is lifted.

[0033] The end of the liquid outlet 16 away from the sample container 14 is inclined upward, which can prevent the agricultural product sample from entering the liquid outlet 16.

[0034] The height of the clamping groove 22 is less than the thickness of the gold standard detection card 21, the top of the gold standard detection card 21 extends out of the clamping groove 22, which can facilitate the taking out of the gold standard detection card 21. One end of the clamping groove 22 is open and the other end is closed, which can facilitate the positioning of the gold standard detection card 21 and facilitate the taking out of the gold standard detection card 21.

[0038] Subsequently, the linear actuator 8 drives the lifting frame 9 to descend, so that the lifting frame 9 descends from the second height position to the third height position, the arc-shaped baffle 23 continuously closes the liquid outlet 16, and the circular baffle 24 descends below the liquid inlet 15 to prevent the material from entering the liquid inlet 15 and the liquid outlet 16 during stirring;

[0039] Subsequently, the rotary power element 10 drives the rotating shaft 11 and the blade 12 to rotate, and the agricultural product material is cut and stirred, the high-frequency oscillation signal emitted by the ultrasonic generator of the constant-temperature ultrasonic cleaning machine 5 is converted into high-frequency mechanical oscillation by the transducer and transmitted to the sample, the sample vibrates under the action of the sound field, and the sample is stirred by the high-frequency sound wave of the ultrasonic wave, so that the residual veterinary drug and pesticide in the sample are dissolved in the extraction liquid; the constant-temperature ultrasonic cleaning machine 5 can heat the water and keep the water at a constant temperature, and the sample in the sample container 14 is heated to promote the dissolution of the residual veterinary drug and pesticide in the sample.

[0040] Finally, the linear actuator 8 drives the lifting frame 9 to rise to the first height position, and after standing and cooling for a period of time, the liquid outlet peristaltic pump 4 draws the upper liquid to be detected into the sample container 14 through the sample input pipe 19 and the liquid outlet 16, and the liquid outlet peristaltic pump 4 transports a certain amount of liquid to be detected to the detection area of the gold mark detection card 21 through the sample output pipe 20, and whether the agricultural veterinary drug residue is qualified is judged by observing the color of the quality control line of the display area of the gold mark detection card 21.

[0041] During the whole process, only the step of putting the sample container 14 into the limiting frame 13 needs to be operated by the operator, and the other steps can be automatically completed, which can avoid the introduction of other impurities and the pollution of the sample, and the accuracy of the detection result is higher;

[0042] After the detection is completed, the extraction liquid output pipe 18 is pulled out of the liquid inlet 15, the sample input pipe 19 is pulled out of the liquid outlet 16, the sample container 14 is pulled up through the handle 27 to overcome the magnetic attraction force between the magnet 26 and the handle 27, the sample container 14 is taken out, the sample container 14 is cleaned, and the blade 12, the rotating shaft 11, the arc-shaped baffle 23, the circular baffle 24 and the like are also cleaned, the input end of the sample input pipe 19 is connected to a distilled water source, the output end of the sample output pipe 20 is provided with a sewage collection container, the liquid outlet peristaltic pump 4 is started, the sample input pipe 19, the liquid outlet peristaltic pump 4 and the sample output pipe 20 are cleaned by distilled water, and the waste water enters the sewage collection container, so that the sample input pipe 19, the liquid outlet peristaltic pump 4 and the sample output pipe 20 are cleaned, and the next detection is facilitated.
