The utility model has the advantages and positive effects that:

1. the centrifugal dedusting fan blade adopts the three-section type fan blade which is obliquely arranged, so that the centrifugal efficiency of the crushed straw is higher under the acceleration of the three-section type fan blade.

2. The utility model adopts a combination mode of crushing and soft silk crushing, so that the crushing efficiency of the straw is greatly improved on the basis of higher crushing degree of the crushed straw.

3. According to the utility model, the movable knife group is matched with the movable knife group to break up and crush the straws, so that the crushing capacity of the movable knife group section is increased, the crushing time can be reduced, and the crushing efficiency can be improved. The kneading disc is additionally arranged on the side of the soft silk hammer (flail knife), so that the crushing and silk softening time can be increased while the crushing and silk softening efficiency is higher.

4. According to the utility model, the guiding moving blades are additionally arranged on the feeding side and the discharging side, so that the efficiency of straw entering and the efficiency of straw crushing and discharging are higher, and the problem of straw clamping can be effectively solved.
