[0032] The rotation of the driving motor 103 drives the separation disc 102 to rotate, producing stirring effect.

[0033] As a preferred scheme of the pesticide extraction device for pesticide detection, the diameter of the rotating shaft 203 is the same as the width of the inner cavity of the first limiting frame 201, the diameter of the rotating shaft 203 is greater than the sum of the diameters of the two guide columns 207, the curved surface of the guide column 207 is attached to the inner wall of the second limiting frame 206, and the second limiting frame 206 is vertically arranged between the first limiting frame 201.

[0034] As a preferred scheme of the pesticide extraction device for pesticide detection, the diameter of the rotating shaft 203 is the same as the width of the inner cavity of the first limiting frame 201, the diameter of the rotating shaft 203 is greater than the sum of the diameters of the two guide columns 207, the curved surface of the guide column 207 is attached to the inner wall of the second limiting frame 206, and the second limiting frame 206 is vertically arranged between the first limiting frame 201.

[0035] As a preferred scheme of the pesticide extraction device for pesticide detection, the diameter of the rotating shaft 203 is the same as the width of the inner cavity of the first limiting frame 201, the diameter of the rotating shaft 203 is greater than the sum of the diameters of the two guide columns 207, the curved surface of the guide column 207 is attached to the inner wall of the second limiting frame 206, and the second limiting frame 206 is vertically arranged between the first limiting frame 201.

[0036] Through the action force of the spring 210, the rotating shaft 203 is in the uppermost position, so that the two guide columns 207 are pushed away, so that the two sealing frames 204 are in the unfolded state when there is no external force, thereby facilitating the placement of crops.

Then, the rotating shaft 203 is pressed to move the rotating shaft 203 downward. During the process, the two guide posts 207 will gradually approach each other, thereby driving the two sealing frames 204 to gradually close, and finally confining the crops in the net bag 205. Then, the connecting frame 208 is rotated and the two guide posts 207 are covered, thereby fixing the guide posts 207 and the rotating shaft 203 to prevent the net bag 205 from being separated. It is opened, and then the separation disc 102 is driven to rotate by the rotation of the driving motor 103, so that the net bag 205 rotates with the crops in the isolation box 101. During the stirring process, the pesticide residues on the surface of the crops are washed and dissolved in the water, and when the separation disc 102 rotates, the base 202 also starts to rotate at the same time under the drive of the gear ring 212, so that the base 202 drives the crops to rotate, and the separation disc 102 drives the crops to revolve, thereby improving the stirring efficiency and shortening the pesticide residue extraction time.

[0040] By turning off the drive motor 103 and replacing the net bag 205 , the crops and residues can be quickly cleaned out, which reduces the difficulty of subsequent cleaning and allows for subsequent pesticide residue detection.
