するようにして取付けられている。As an invention of this type, for example, there is a device described in Japanese Utility Model Laid-Open No. 4-131443 filed by the present applicant earlier. The cutting blade for a shredder of the present invention has a drive shaft 51 as shown in the plan view of the shearing type crusher shown in FIG. 6 and the front view showing the relationship between the cutting blade and the spacer of the shearing type crusher shown in FIG. A plurality of blade mounts 53 and spacers 54 are arranged side by side in the axial direction of the driven shaft 52, and the cutting blades 55 mounted on the blade mounts 53 are mounted in close contact with the adjacent spacers 54.

着してしまう場合がある。By the way, there are various miscellaneous objects to be crushed by this type of shear crusher,
If such an object to be crushed is crushed for a long time, the cutting blade 5
There is a case where the crushed object is adhered between 5 and the cutting blade 55 and the tool mount 53 are brought into close contact with each other due to rust or the like due to moisture in the crushed object.

い。On the other hand, the cutting blade 55 for shear crushing in this way
Crushes various objects to be crushed, such as plastic and wood, so that some of them may be damaged or worn in a short time.
When this cutting blade 55 wears, it wears from the tip and side corners, but if the amount of wear at the corners increases, the shear crushing ability will drop significantly, so cutting that is worn to maintain crushing ability The blade 55 must be replaced. Moreover, such replacement of the cutting blade 55 requires replacement of the cutting blade 55 even if a part of the rotary blade is damaged.

Is stuck to the tool mount 53 due to rust, etc.,
It is very difficult to remove the cutting blade 55 having the spacers 54 in close contact with both sides in the radial direction.
The replacement work requires a lot of time and labor. Moreover, if the rust or the like makes a strong contact, the shafts 51, 52
May have to be disassembled.

The number of cutting blades 9 provided is not limited. Further, the cutting blade 9 does not necessarily have to cover the periphery of the blade mounting base 10, and the cutting blade 9 is attached so as to be in close contact with the blade mounting base 10, and the axial movement of the cutting blade 9 is restricted. The same is applicable in some cases.
