The two sides of the lifting plate are symmetrically and fixedly installed with guiding sliders, and the guiding sliders are embedded in the guiding chute. A lead screw sleeve is fixedly installed in one of the guiding sliders, and the lead screw sleeve is matched with the lifting lead screw. As the lifting lead screw rotates, the lifting plate can be driven to move up and down along the guiding chute until the sealing ring is embedded in the sealing groove and the crushing and grinding knives enter the inner cavity of the grinding box. At this time, starting the driving motor to drive the crushing and grinding knives to rotate can crush and grind the solid food. After grinding is completed, the lifting plate drives the crushing and grinding knives to reset, and then the grinding box is rotated 180 degrees. At this time, the opening of the grinding box faces downwards, and the obtained food powder can be discharged into the collection box for subsequent food detection. For the powder partially adhered to the inner wall of the grinding box, the user can start the electric push rod through the control panel. Under the push of the electric push rod, the discharging scraper can be pushed to move along the inner wall of the grinding box to scrape and discharge the food material on the inner wall of the grinding box. Since the crushing and grinding knives are not in the inner cavity of the grinding box, the user can easily clean the inner cavity of the grinding box for the next use, and the practicability is stronger.

Finally, the mounting screws 16 are screwed into the first threaded holes 25 and the second threaded holes to realize the fixed installation of the crushing and grinding knife 8. When the crushing and grinding knife 8 needs to be cleaned or is severely worn, the mounting shaft 14 and a number of crushing and grinding knives 8 can be removed from the inner cavity of the grinding box 4, and then the mounting ring 26 together with the crushing and grinding knife 8 can be disassembled according to the above steps for easy cleaning or replacement, thus bringing convenience to the use and maintenance of a grinding machine for food detection pretreatment, with stronger practicability. In addition, the utility model is provided with a grinding box 4, a lifting plate 11 and a discharging scraper 7. During use, the grinding box 4 can be rotated with the opening facing upwards by using the bearing seat 21 and the rotating shaft 18. By pushing the push-pull sliding rod 6 sleeved in the sliding sleeve 22, the limit pin 23 is inserted into the limit hole 24 provided on the side wall of the grinding box 4, which can prevent the grinding box 4 from rotating during use. Then the user can place the solid food to be detected in the inner cavity of the grinding box 4, and then start the servo motor 10 installed on the top of the side plate 5 through the control panel. The servo motor 10 drives the lifting lead screw 9 installed in the guiding chute 13 to rotate. The guiding sliding blocks 19 are symmetrically and fixedly installed on both sides of the lifting plate 11, and the guiding sliding blocks 19 are embedded in the guiding chute 13. A lead screw sleeve 20 is fixedly installed in one of the guiding sliding blocks 19, and the lead screw sleeve 20 is matched with the lifting lead screw 9. As the lifting lead screw 9 rotates, the lifting plate 11 can be driven to lift along the guiding chute 13 until the sealing ring 15 is embedded in the sealing groove 17 and the crushing and grinding knife 8 enters the inner cavity of the grinding box 4. At this time, starting the driving motor 12 to drive the crushing and grinding knife 8 to rotate can crush and grind the solid food. After the grinding is completed, the lifting plate 11 drives the crushing and grinding knife 8 to reset, and then the grinding box 4 is rotated 180 degrees. At this time, the opening of the grinding box 4 faces downwards, and the obtained food powder can be discharged into the collection box 2 for subsequent food detection. For the powder partially adhered to the inner wall of the grinding box 4, the user can start the electric push rod 3 through the control panel. Under the push of the electric push rod 3, the discharging scraper 7 can be pushed to move along the inner wall of the grinding box 4, and the food materials on the inner wall of the grinding box 4 can be scraped and discharged. Since the crushing and grinding knife 8 is not in the inner cavity of the grinding box 4, the user can easily clean the inner cavity of the grinding box 4 for the next use, with stronger practicability.
