[0026] Two supporting legs are fixedly connected to both sides of the bottom of the grinding box 100, and the four supporting legs are used to support the entire device.

At the same time, the raw materials can be discharged by spiral conveying after grinding, reducing the risk of clogging of the discharge pipe 12.

[0027] Working principle: When in use, start the driving motor 4, then unscrew the plugging cover from the discharge pipe 12, and place a collecting box under the discharge pipe 12. The output shaft of the driving motor 4 drives the vertical rod 5 to rotate, and the vertical rod 5 drives the multiple crushing rods to rotate, and the raw materials to be ground are added into the feed pipe 1 through the conical feed hopper 2. The multiple crushing rods in rotation perform preliminary crushing operations on the incoming raw materials, and the crushed raw materials fall onto the two guide plates 16 in the first grinding hole 15. At the same time, the two first vibrators 17 are turned on, and the first vibrators 17 vibrate the corresponding guide plates 16 to vibrate the guide plates 16.

After the primary grinding, the raw material falls into the second grinding hole 10. The vertical rod 5 also drives the second grinding block 11 to rotate. The second grinding block 11 drives a plurality of grinding sharp blocks to rotate. While the plurality of grinding sharp blocks rotate, the raw material in the second grinding hole 10 is secondary ground. The ground raw material falls onto the bottom inner wall of the grinding box 100. By crushing the raw material and then grinding it, it is possible to effectively reduce the situation where larger pieces of raw material enter the first grinding hole 15 and cause the first grinding block 14 to get stuck. In addition, by setting up two grinding mechanisms, the raw material can be secondary ground to improve the grinding effect. While grinding, the four second vibrators 13 are turned on. The second vibrators 13 vibrate the corresponding support rods 6. Under the excitation force, the raw material that falls onto the support rods 6 can be effectively shaken off, thereby reducing the amount of raw material adhering to the support rods 6.

[0028] When the vertical rod 5 rotates, it also drives the spiral conveying blade 9 to rotate. When the spiral conveying blade 9 rotates, the raw materials that fall into the grinding box 100 are spirally conveyed downward to the discharge pipe 12, and discharged to the outside through the discharge pipe 12. By spirally conveying the raw materials downward to discharge them, the risk of clogging of the discharge pipe 12 during the discharge process can be effectively reduced, and the discharge stability can be improved. The single drive can simultaneously realize crushing, secondary grinding and feeding, which is energy-saving and convenient to operate.
