Specific embodiment
In order to be more clearly understood that technology contents of the invention, spy lifts following embodiment and is described in detail.
It is the embodiment for the crushing knife tool 1 that the present invention uses as shown in Fig. 1~2, wherein the crushing knife tool includes edge
The equally distributed several cutter tooth rows 2 of the circumferential surface of the crushing knife tool, each cutter tooth row are disposed relative to institute
The angled α of the axial direction for the crushing knife tool stated, in two neighboring cutter tooth row, the end cutter tooth and the second cutter tooth of the first cutter tooth row is arranged
Head end cutter tooth be arranged on the same straight line parallel with the axial direction of the crushing knife tool so that the crushing knife tool exists
During circumgyration incision material, the same time has and a cutter tooth 4 in only one cutter tooth row is in cutting state.
Crushing knife tool of the invention is arranged to have in the same time and a cutter tooth in only one cutter tooth row is in and cuts
Cut state, that is, during circumgyration incision, the end cutter tooth of upper slitter tooth row and the head end cutter tooth for cutting tooth row in adjacent cutter tooth row
Can mutually it be connected.
As shown in Figure 1, it is shown that the crushing knife tool includes three identical crushing cutter hubs 3, and each crushing cutter hub is equal
Along the axial direction setting of the crushing knife tool, cutter tooth distribution having the same on each crushings cutter hub, and from the axis of crushing cutter hub
Always it sees, each cutter tooth is distributed along oblique line, the oblique line and the angled α of axial direction for crushing cutter hub.To form whole crushing knife tool
Cutter tooth row, as shown in figure 3, three crushing cutter hubs are during installation, second crushing cutter hub is deflected relative to first crushing cutter hub
Angle beta installation, third crush cutter hub and install relative to second crushing cutter hub deflection angle β, i.e., each crushing knife
