Meanwhile, the pulverizer also comprises a cutting assembly, and the cutting assembly is arranged in the pulverizer body 1 and is positioned between the feeding end 2 and the discharging end 3. Thus, in actual use, the branches enter from the infeed end 2 and pass through the cutting assembly to be shredded and then exit from the outfeed end 3.

Wherein the length of discharge end 3 compares with the discharge end 3 of contrast file in the background art, the utility model discloses a length is longer, has increased the length of a changeover portion promptly rather than directly going out from the 3 exports of discharge end. This is because the ejection of compact of discharge end 3 can present the orbit of parabola, and thus length is longer can have certain transition effect, and then can avoid the jam of export and be convenient for the clearance. Meanwhile, the length of one transition section is increased, so that the cutting assembly is prevented from being touched by a hand easily in cleaning, and accidents are avoided.

And the pulverizer also comprises a roller shaft 4, and the roller shaft 4 is rotatably arranged in the machine body 1 and is positioned between the feeding end 2 and the cutting assembly. Therefore in the in-service use process, when the branch comes in from feed end 2, can be earlier when passing through roller 4, and thereby accessible roller 4 transports the branch to cutting assembly, and then makes the branch can reach cutting assembly fast.

Furthermore, a plurality of pressing plates 7 with saw teeth 6 are arranged on the periphery of the roller shaft 4, and the branches are pressed through the pressing plates 7 so as to be compact and tidy. Therefore, the abrasion of the rotating cutter shaft 5 by disordered branches can be avoided; and because the existence of sawtooth 6 can increase friction to can carry out spacing to the branch when not cutting up, thereby avoid thin branch to slide away.

The pressing plate 7 and the roller shaft 4 can be integrally formed or the pressing plate 7 is welded on the roller shaft 4, and the section of the sawtooth 6 is triangular and can also be trapezoidal.

And the positional relationship of the pressing plate 7 and the roller shaft 4 is of two kinds: the first is that a plurality of pressing plates 7 are axially arranged on the circumference of the roller shaft 4, namely, the pressing plates 7 are parallel to the central line of the roller shaft 4. The second is that a plurality of pressing plates 7 are radially arranged on the circumference of the roller shaft 4, namely the pressing plates 7 are perpendicular to the central line of the roller shaft 4.
