[0028] See Figures 1-4 This embodiment describes an integrated agricultural product pesticide residue crushing and extraction device. It integrates multiple functions such as crushing, stirring, heating, and centrifugal separation into one unit, achieving fully automated operation from agricultural product feeding to residue extraction and separation. This reduces the connection and transmission steps between multiple devices in traditional equipment, improving work efficiency and saving space. In this embodiment, it mainly includes an extraction cylinder 1, with a feed inlet 7 at the top side. Agricultural products are fed into the extraction cylinder 1 through the feed inlet 7. The interior of the extraction cylinder 1, from top to bottom, consists of a crushing chamber 2, a control chamber 3, and a stirring chamber 4. A first partition 8 is horizontally fixed inside the extraction cylinder 1 between the control chamber 3 and the crushing chamber 2. The first partition 8 has a bucket-shaped structure that is wider at the top and narrower at the bottom. Agricultural products enter the crushing chamber 2 above the first partition 8.
[0029] A rotating rod 9 is vertically rotatable at the center of the crushing chamber 2. At least one chopping blade 10 is horizontally and coaxially fixed on the rotating rod 9. A first motor 11, which drives the rotating rod 9, is fixedly installed at the top of the extraction cylinder 1. A second partition 12 is horizontally fixed inside the extraction cylinder 1 between the control chamber 3 and the stirring chamber 4. A connecting pipe 13 is vertically fixed at the center of the first partition 8 and the second partition 12. The two ends of the connecting pipe 13 are connected to the crushing chamber 2 and the stirring chamber 4, respectively. A solenoid valve 14 is installed on the connecting pipe 13. Controlling the solenoid valve 14 closes the passage of the connecting pipe 13, controls the first motor 11 to work, pours liquid into the crushing chamber 2 inside the extraction cylinder 1, drives the rotating rod 9 to rotate the chopping blade 10, and crushes the agricultural products. When the crushing reaches a certain degree, controlling the solenoid valve 14 opens the passage of the connecting pipe 13. At this time, the mixture enters the interior of the stirring chamber 4 through the connecting pipe 13.
[0030] To achieve the extraction of pesticide residues. See also Figure 2 , Figure 3 and Figure 4 In this embodiment, multiple metal rods 15 are arranged circumferentially around the center of the mixing chamber 4. A rotating roller 16 is fitted onto each metal rod 15, and at least one set of stirring paddles 17 is horizontally fixed on each rotating roller 16. Each set of stirring paddles 17 is arranged circumferentially around the metal rod 15, and at least three of them are arranged. A through groove 18 is formed along the length of each rotating roller 16, and at least one through groove 18 is provided. Multiple second motors 19 are fixedly installed inside the control chamber 3, and each second motor 19 drives the corresponding rotating roller 16 to rotate. An appropriate amount of extraction reagent is added to the extraction cylinder 1, and then the second motors 19 are controlled to operate, driving the rotating roller 16 to make the stirring paddles 17 rotate on the metal rods 15, thereby mixing the liquid, extraction reagent, and crushed agricultural products.
[0031] A heating unit 5, which cooperates with the stirring chamber 4, is fixedly installed on the extraction cylinder 1. The heating unit 5 includes a heating ring 51 sleeved on the outside of the extraction cylinder 1. The heating ring 51 is a hollow structure and is located outside the metal rod 15. An electromagnetic coil 52 is installed inside the heating ring 51. The electromagnetic coil 52 is a mature existing technology and will not be described in detail here. During the mixing process, the electromagnetic coil 52 is controlled to work, heating the metal rod 15 and bringing it into contact with the mixture through the through groove 18. This heating of the mixture in the stirring chamber 4 accelerates the mixing reaction of the solvent and the sample, improves the extraction efficiency, and shortens the experimental time.
[0032] A centrifuge 6 is installed on the side of the extraction cylinder 1, and the centrifuge 6 is connected to the bottom of the stirring chamber 4. A discharge port 20 is provided at the bottom of the stirring chamber 4, and a discharge pipe 21 is connected to the bottom of the discharge port 20. The discharge pipe 21 is connected to the inlet 7 of the centrifuge 6. A solenoid valve 14 is also installed on the discharge pipe 21 on the side of the discharge port 20. During stirring, the solenoid valve 14 is activated to close the discharge pipe 21. A discharge pipe 22 is connected to the discharge pipe 21 on the side of the centrifuge 6, and the solenoid valve 14 is also installed on the discharge pipe 22. After mixing, the solenoid valve 14 is activated to open the discharge pipe 21.

Afterwards, the solenoid valve 14 is activated to open the discharge pipe 22, and the remaining mixture is discharged from the discharge pipe 22.
[0033] The method of using the integrated agricultural product pesticide residue crushing and extraction equipment of this utility model is as follows: First, the agricultural product is fed into the extraction cylinder 1 through the feed inlet 7. The agricultural product enters the crushing chamber 2 above the first partition 8. The solenoid valve 14 is controlled to close the channel of the connecting pipe 13, and the first motor 11 is controlled to work, pouring liquid into the crushing chamber 2 in the extraction cylinder 1, driving the rotating rod 9 to drive the chopping blade 10 to rotate, crushing the agricultural product. When crushing to a certain extent, the solenoid valve 14 is controlled to work, opening the channel of the connecting pipe 13. At this time, the mixture enters the interior of the stirring chamber 4 through the connecting pipe 13. At this time, the corresponding solenoid valve 14 is controlled to work, closing the channel of the discharge pipe 21.
[0034] An appropriate amount of extraction reagent is added to the extraction cylinder 1. Then, the second motor 19 is controlled to operate, driving the rotating roller 16 to make the stirring paddle 17 rotate on the metal rod 15, thereby mixing the liquid, extraction reagent, and crushed agricultural products. During the mixing process, the electromagnetic coil 52 is controlled to operate, heating the metal rod 15 and making it contact the mixture through the through groove 18, thus heating the mixture in the stirring chamber 4, accelerating the mixing reaction between the solvent and the sample, improving the extraction efficiency, and shortening the experimental time. After mixing, the electromagnetic valve 14 is driven to open the channel of the discharge pipe 21. At this time, the channel of the discharge pipe 22 is closed under the action of the corresponding electromagnetic valve 14, and the mixture enters the centrifuge 6 for extraction. Afterwards, the electromagnetic valve 14 is controlled to open the channel of the discharge pipe 22, and the remaining mixture is discharged from the discharge pipe 22.
