A frame 9 is fixedly connected to the rear side of the main housing 1. A driving motor 10 is arranged at the rear side of the frame 9. A controller 13 is arranged on the right side of the main housing 1.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , The bottom of the table board 14 is fixedly connected to the main housing 1. A feeding pipe 16 is communicated with the bottom of the crushing box 15. The bottom end of the feeding pipe 16 penetrates through the table board 14 and is communicated with the main housing 1. Servo motors 17 are bolted to both sides of the crushing box 15. The output ends of the servo motors 17 all penetrate into the inner cavity of the crushing box 15 and are fixedly connected with crushing rollers 18. A feeding pipe is bolted to the top of the crushing box 15. Guide blocks are fixedly connected to the front and rear sides of the bottom of the inner cavity of the crushing box 15. By setting the guide blocks, an auxiliary effect is achieved, so that the flow rate of the crushed material can be accelerated, preventing it from accumulating inside the crushing box 15 and getting blocked. The output end of the controller 13 is unidirectionally electrically connected to the servo motors 17.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , The bottom ends of the guide rods 19 are all slidably connected through the main housing 1. Springs 21 are fixedly connected to the four corners of the bottom of the screening box 20. By setting the springs 21, an auxiliary effect is achieved, so that the shaking amplitude and stability of the screening box 20 during the screening process can be enhanced, enabling it to screen the sample material more efficiently. The bottom ends of the springs 21 are all fixedly connected to the main housing 1. A vibration motor 22 is arranged at the bottom of the screening box 20. Screening plates 23 are arranged at the top of both sides of the inner cavity of the screening box 20.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 。 The top of the partition plate 4 is fixedly connected through penetration with a discharge pipe 11. The output end of the driving motor 10 penetrates through the frame 9 and is fixedly connected with a pulley group 8. The number of grinding rollers 7 is three groups. Both sides of the main housing 1 are fixedly connected through penetration with heat dissipation fans 12. By setting the heat dissipation fans 12, an auxiliary effect is achieved, so that it can be started when necessary and the grinding plate 5 can be cooled, preventing the sample material from deteriorating due to excessive temperature. The output end of the controller 13 is unidirectionally electrically connected to the heat dissipation fans 12 and the driving motor 10 respectively.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 。 Dust-proof plates are fixedly connected to both sides of the main housing 1.

By setting the feet, an auxiliary effect is achieved, so that the wear on the bottom of the main housing 1 during use can be reduced, and the stability of the device can also be increased.

[0028] In use, first add the sample material into the crushing box 15 through the feeding pipe. At this time, the material needs to be crushed first. First, start the servo motor 17 through the controller 13. The servo motor 17 drives the crushing roller 18 to rotate. The two groups of crushing rollers 18 rotate relatively to simply crush the sample material, and finally flow into the main housing 1 through the material passing pipe 16. This mechanism can effectively perform pre-crushing treatment, thereby reducing the wear of the sample material on the grinding equipment and improving the efficiency of subsequent detection. Thus, the pre-crushing treatment is completed. After flowing into the main housing 1, start the driving motor 10 through the controller 13. The driving motor 10 runs to drive the three groups of grinding rollers 7 to rotate through the pulley group 8, and cooperate with the grinding plate 5 to grind the sample material. When necessary, the controller 13 can be used to start the cooling fan 12 to cool the grinding plate 5. The ground sample material flows into the screening assembly through the discharge pipe 11. At this time, screening is required. First, start the vibration motor 22 through the controller 13. The vibration motor 22 drives the screening box 20 to vibrate along the spring 21 and the guide rod 19. The internal screening plate 23 screens the ground sample material. The finer material will fall downward and be discharged through the first material pipe, and the coarser material will be discharged to the right through the second material pipe. This mechanism can effectively perform screening treatment, thereby selecting fine ground sample material and avoiding the influence of incompletely ground sample material on the detection results, and then ensuring the accuracy of the detection. Thus, the automatic screening treatment is completed.

[0029] In summary, the sample grinding device for food detection with a screening function solves the problems that the existing sample grinding device does not have pre-crushing treatment and automatic screening function during use through the cooperation of the table board 14, the crushing box 15, the material passing pipe 16, the servo motor 17, the crushing roller 18, the guide rod 19, the screening box 20, the spring 21, the vibration motor 22 and the screening plate 23.
