Described hub disk is conical structure, and the middle part of described hub disk is provided with pivot pin connecting hole, bolt connecting hole, rotor shaft hatch, is provided with key link slot in described rotor shaft hatch.
Described shroud is loop configuration.
The quantity of described crushing knife is multiple, and described multiple crushing knife array distribution in the form of a ring centered by the center of circle of described shroud.
The retainer ring being positioned at described crushing knife front end is embedded in the rear end of described shroud, and the retainer ring being positioned at described crushing knife rear end is embedded in the front end of described hub disk.
Described set bolt is positioned at the inner side of described retainer ring.
The quantity of described pivot pin connecting hole, bolt connecting hole is 4, and described pivot pin connecting hole, bolt connecting hole all with the center of described rotor shaft hatch for center of circle array distribution in the form of a ring.
Described pivot pin connecting hole runs through described hub disk, and described bolt connecting hole is embedded in the front end of described hub disk.
The eddy mill rotor grating disk obtained by above-mentioned design of the present utility model, its beneficial effect is:
Combination is pulverized when the application of cutterhead makes crushing knife be subject to material impact more firm;
Cutterhead is pulverized in combination, can load and unload when damaging to specific crushing knife, reduces maintenance cost.
Whole crushing knife is broken multiple pulverizing shearing point, pulverizing speed is accelerated, improves labor productivity;
Material well can be sheared and promote the friction of material itself and mix greatly by the crushing knife that in rotor grating disk, each side stretches out, and forms 3 D stereo shear effect, greatly improves crushing effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural representation of eddy mill rotor grating disk described in the utility model; Fig. 2 is the side-looking structural representation of eddy mill rotor grating disk described in the utility model, as shown in Figure 1 and Figure 2, a kind of eddy mill rotor grating disk, comprise shroud 1, hub disk 2, crushing knife 3, described shroud 1 is connected by fastening bolt 4 with hub disk 2, described crushing knife 3, between described shroud 1 and hub disk 2, is undertaken connecting by retainer ring 5 between described crushing knife 3 and is fixed by set bolt 6.
Described crushing knife 3, in " work " shape structure, is all embedded with retainer ring 5 in two, the left and right groove of described crushing knife 3 " work " shape structure.
Described hub disk 2 is conical structure, and the middle part of described hub disk 2 is provided with pivot pin connecting hole 7, bolt connecting hole 8, rotor shaft hatch 9, is provided with key link slot 10 in described rotor shaft hatch 9.
Described shroud 1 is loop configuration.
The quantity of described crushing knife 3 is multiple, and described multiple crushing knife array distribution in the form of a ring centered by the center of circle of described shroud 1.
The retainer ring 5 being positioned at described crushing knife 3 front end is embedded in the rear end of described shroud 1, and the retainer ring 5 being positioned at described crushing knife 3 rear end is embedded in the front end of described hub disk 2.
Described set bolt 6 is positioned at the inner side of described retainer ring 5.
The quantity of described pivot pin connecting hole 7, bolt connecting hole 8 is 4, and described pivot pin connecting hole 7, bolt connecting hole 8 all with the center of described rotor shaft hatch 9 for center of circle array distribution in the form of a ring.
Described pivot pin connecting hole 7 runs through described hub disk 2, and described bolt connecting hole 8 is embedded in the front end of described hub disk 2.
Flow process changed by cutterhead:
Back out the nut be connected with described fastening bolt 4;
Take off described fastening bolt 4;
Back out the set bolt 6 of front end;
Take off shroud 1;
Take out the retainer ring 5 being positioned at front end;
