[0045] During the actual operation process, when this device is in use, the ear bracts are poured into the processing box 1 through the feeding bin 2. The motor 511 is started to operate, driving the front crushing roller 513 to rotate through the front rotating shaft 512. The front rotating shaft 512 drives the front gear 514 to rotate. The rear end of the front gear 514 meshes with the rear gear 515, and the rear gear 515 drives the rear rotating shaft 516 to rotate in the reverse direction. The rear rotating shaft 516 drives the rear crushing roller 517 to rotate in the reverse direction.

The transmission rod 538 is hinged to drive the movable plate 537 to lift and lower, and the movable plate 537 drives the sieve plate 535 to lift and lower. The sieve plate 535 lifting and lowering repeatedly drives the ear bracts to vibrate, enabling the chopping knife 524 to chop evenly and avoiding blockage of the sieve plate 535. The sieve plate 535 is supported by the support block 534, and the support spring 533 is used to buffer the downward movement of the sieve plate 535 to avoid damage to the sieve plate 535 caused by collision. At the same time, the limit block 6 is used to limit the upward reset of the sieve plate 535 to prevent the sieve plate 535 from contacting the chopping knife 524.
