It is preferred that, the blade is by for chrome-moly steel material, and blade is leaned on and cutterhead is formed in one structure.

It is preferred that, the one side that the blade is leaned on is faces directly, and the another side that blade is leaned on is arcwall face.

It is preferred that, the part that the handle of a knife extends to inside grooves is fixed by fixing nut, and the thickness of fixing nut Less than the depth of groove.

It is preferred that, the internal diameter of the through hole is less than the internal diameter of groove, and the external diameter of the fixing nut of handle of a knife is equal to groove Internal diameter.

It is preferred that, the internal diameter of two perforation is all higher than the external diameter of screw mandrel.

This technology has the beneficial effect that：

1. being fixed on the first motor that movable knife disc is rotated on contiguous block, contiguous block can be by the second motor with being moved down on screw mandrel It is dynamic, cutterhead is moved up and down, timber is processed with the need for tackling different thicknesses size, improves the efficiency of wood chipping equipment.

2. each blade of cutterhead is installed with two fastening bolts, thrust is strong, blade is brought into close contact with cutterhead, and rigidity increases By force, reduce the blade caused by vibrations to be lost, cost is lower, and processing effect is more preferable.
