[0031] Working principle: Before using this pretreatment device for detecting vegetable pesticide residues, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, a rotating assembly 2 is provided at the top and bottom of the cover plate 102. When preprocessing vegetables, the vegetables are placed inside the cup body 1, and then the cover plate 102 is covered. The drive motor 2011 inside the housing 201 is started to drive the rotating shaft 202 to rotate. After the rotating shaft 202 rotates, it drives the square rod 203 to rotate, so that the square sleeve 204 and the rotating blade 205 can rotate, and the vegetables can be crushed. While the rotating shaft 202 rotates, the engagement of the first bevel gear 206 and the second bevel gear 209 can drive the rotating rod 208 to rotate on the fixed frame 207, so that the turntable 210 rotates, and then the column block 211 rotates in a circle. The column block 211 can drive the movable frame 212 to move by sliding connection with the movable frame 212, so that the movable frame 212 moves reciprocally. While the movable frame 212 moves, it drives the fixed sleeve 213 to slide on the support rod 214 for positioning. Furthermore, the L-shaped rod 215 can be used to pull the mounting sleeve 216 to move up and down. While the square sleeve 204 rotates, the fixed ring 218 slides inside the annular groove 217. The up and down movement of the mounting sleeve 216 can drive the square sleeve 204 to move up and down, thereby expanding the rotation range of the rotating blade 205 and accelerating the crushing efficiency of the vegetables. Open the valve on the liquid outlet pipe 101 to discharge the juice generated by the crushing of the vegetables. By making the rotating shaft 202 rotate through the rotating assembly 2, the rotating blade 205 can rotate and move up and down, expanding the stirring range, saving the use cost and manufacturing cost, and improving the practicability;

[0032] A number of connecting components 3 are provided at the bottom of the cover plate 102. When positioning the cover plate 102, the cover plate 102 is covered on the top of the cup body 1, and then the movable rod 302 is pulled and the rotating sleeve 301 is rotated, so that the movement of the movable rod 302 stretches the telescopic spring 303. Then, the positioning block 306 on the mounting rod 304 is aligned with the positioning groove 307 on the fixed block 305, and the movable rod 302 can be released. Under the action of the telescopic spring 303, the positioning block 306 is engaged with the positioning groove 307, thereby limiting the cover plate 102. The connecting component 3 facilitates the removal and fixing of the cover plate 102, facilitates the cleaning of the cup body 1 and the filter cover 103, and facilitates the placement of vegetables, improving the practicability.
