Piece is made up of vane body with the cutter tooth for being located at vane body outline position, and the quantity of cutter tooth is 1-12, and multiple cutters tooth
It is distributed uniformly and circumferentially, each cutter tooth is constituted by rake face and rear knife face are intersecting, and rear knife face is used by Archimedes spiral
The curvilinear plane of formation, the anterior angle formed by rake face, the relief angle formed by rear knife face；In the vane body of each disk blade
Center is equipped with blade mounting holes, and blade mounting holes are made up of two symmetrical and concentric arc surfaces and two symmetrical planes, and first
The outer contour shape of the outer contour shape of cutter shaft and the second cutter shaft is consistent with the shape of blade mounting holes, and disk blade passes through knife
Piece mounting hole and corresponding cutter shaft formation being fixedly connected along the circumferential direction.
It is preferred that：The anterior angle is 45 °, and the relief angle is 3.78 °.
It is preferred that：Pass through disk blade center provided with one in the rake face of each cutter tooth and the intersection location of rear knife face
Section.
It is preferred that：Disk blade is made up of M42 steel, and grade of steel is W6Mo5Cr4V2Co8.
The utility model has the advantages and positive effects of：
1st, each cutter tooth of plate-like cutterhead is provided with anterior angle and relief angle, can so form sharp blade, sharp blade has
Beneficial to the broken of rubbish, so as to improve the crushing efficiency of rubbish.
2nd, rear knife face use by Archimedes spiral into curvilinear plane, blade has refacing property, and refaced in cutter
When, relief angle size will not be changed, the durability of cutter can be so improved.
3rd, blade is coordinated with corresponding cutter shaft by two symmetrical planes, to realize the transmission of moment of torsion, with mating surface
Few, assembling is not susceptible to the advantage of interference, and cutter shaft is simple to manufacture in addition, rigidity reinforced, can carry out strength broken.
