[0027] The specific implementation method is as follows: by setting up an impurity removal and cleaning component 9, the fixed motor 902 can drive the synchronous opening and closing of multiple flip plates 901 by rotating the gear plate 907 and the driving gear 906, ensuring that the bottom of the processing box 2 can be opened or sealed quickly and accurately. The synchronous movement design of the flip plate 901 avoids the problem of local jamming or poor sealing, ensuring that impurities such as hard stones are discharged smoothly. Through the closing and opening between multiple flip plates 901, the bottom of the processing box 2 can be quickly closed and opened, and the hard impurities can be quickly discharged and cleaned.

[0028] Working principle: When in use, the staff starts the driving motor 301, and the staff puts the soil sample into the processing box 2 through the sample feed hopper 1. The driving motor 301 drives the main shaft 304 to rotate, and the main shaft 304 drives the crushing whip 305 to rotate at high speed, thereby performing preliminary crushing processing on the large pieces of soil samples. Moreover, since the crushing whip 305 is made of flexible material, it will only crush the soil sample without affecting the hard stones mixed therein. The soil sample that has been preliminarily crushed falls onto the flip plate 901. During this process, the main shaft 304 drives the protective shell 308 to drive the conveying auger 306 and the grinding roller 307 to revolve through the driving shaft. In this process, the transmission gear 310 cooperates with the fixed gear ring 309 to drive the driving shaft to rotate, driving The shaft drives the grinding roller 307 and the conveying auger 306 to rotate. The grinding roller 307 cooperates with the flip plate 901 to refine and crush the soil sample. The conveying auger 306 drives the ground sample to move toward the outer peripheral side of the processing box 2, so that after the soil sample is screened by the filter plate 303, the qualified part passes through the filter plate 303 and enters the central hopper 4 through the connecting pipe 302, while the stone particles in the sample remain in the processing box 2. In this process, the grinding roller 307 drives the linkage gear 316 to revolve around the connecting gear disc 312 through the rotating shaft 315, so that the linkage gear 316 rotates. The linkage gear 316 drives the counterweight block 313 to rotate eccentrically through the rotating shaft 315 and the connecting rod 314, thereby generating eccentric vibration and transmitting the vibration to the grinding roller 307.

[0029] The ground soil sample enters the centralized hopper 4 through the connecting pipe 302 and is discharged through the discharge square pipe 7. At this time, the staff installs different numbers of receiving boxes 601 in the installation slot 610 according to the reduction requirements. The number of receiving boxes 601 can be 2, 4 or 8. After that, the staff starts the driving device 608, and the driving device 608 drives the rotating disc 609 to rotate. The rotating disc 609 drives the receiving box 601 to rotate through the installation slot 610, and the receiving box 601 drives the toggle plate 602 to rotate. During the rotation of the toggle plate 602, it can drive the rotating roller 603 and the connecting round rod 604 to move, and the connecting round rod 604 drives the sealing flap 605 to flip to one side, so that the discharge square tube 7 is opened, so that the soil sample can fall into the receiving box 601. When the toggle plate 602 is separated from the connecting round rod 604, the reset spring 607 drives the sealing flap 605 to reset and makes the sealing flap 605 seal the discharge square tube 7 again. When multiple receiving boxes 601 rotate, the above process is repeated to realize the reduction processing of soil samples.

[0030] After completing the processing of the soil sample, the staff starts the fixed motor 902, and the fixed motor 902 drives the rotating toothed disc 907 to rotate, and the rotating toothed disc 907 drives the driving gear 906 to rotate, and the driving gear 906 drives multiple flip plates 901 to rotate synchronously, so that the sealing disc formed by the flip plate 901 is opened, and the bottom of the processing box 2 is opened, and impurities such as hard stones previously retained in the processing box 2 can automatically fall through the opening. After completing the cleaning of impurities, the fixed motor 902 drives the rotating toothed disc 907 to rotate, and the rotating toothed disc 907 drives the flip plate 901 to reset synchronously through the driving gear 906. In addition, the fixed motor 902 is a self-locking motor, which can prevent the flip plate 901 from flipping and affecting the sealing state of the bottom of the processing box 2.
