The inverted T-block that can be slided up and down along the horizontal part of T-slot is provided on the downside of body；
Be provided with the gland for compressing mobile cutter hub on front side of the cutter hub, the gland by bolt with it is described
Cutter hub is fixedly connected, and the through-hole for accommodating the bolt being set in the T-block is slotted hole.
Further, it is respectively set positioned at the upper and lower both sides of the horizontal part of the T-block in the horizontal part of the T-slot
There are the second backing plate and the first backing plate.
Further, the cutting edge includes the positive alloy cutting edge being set on angle of attack face and is set on dorsal horn face
Negative alloy cutting edge, be provided with bar shaped alloy sword between the positive alloy cutting edge and negative alloy cutting edge.
Further, when the gland is installed on cutter hub, the leading flank of the gland and the leading flank of cutter hub are flat
Together.
Further, the height of the horizontal part of the T-slot is equal to the height of the T-block.
The utility model has the beneficial effects that：
1, by the way that mobile cutter hub moving up and down is arranged in the straight flange portion of cutter hub, to make the digging diameter of edge blade
It can be adjusted as needed, improve the flexibility of edge blade, application is more flexible, more adaptable.
2, mobile cutter hub is compressed by gland, and is not only and is simply connected by screw bolts, such edge blade is being opened
Dig diameter it is adjustable under the premise of, stable structure, securely.
3, easy to operate when being adjusted to digging diameter, it is convenient.
4, effective to be carried out to dorsal horn face by bearing alloy cutting edge in the dorsal horn face setting of cutter hub and mobile cutter hub
Protection avoids the abrasion of stream slag and rubble, extends service life, improve driving speed.

Specific implementation mode
For the convenience of description, it is as shown in Figure 1 now to define coordinate system.
As shown in Figure 1, Figure 2 and shown in Fig. 5, a kind of adjustable twolip edge blade of digging diameter includes cutter hub 1, the cutter hub 1
Top be provided with cutting edge.Inverted T-slot 11 is provided in the straight flange portion of the cutter hub 1, and the T-slot 11 is vertical
The cutter hub 1 is run through in part along the longitudinal direction, and the vertical portion of the T-slot 11 extends upward through the cutter hub 1.The T
It is in communication with the outside on front side of the horizontal component of type groove 11, the rear side of the horizontal component of the T-slot 11 separates with extraneous.
As shown in Figure 4 and Figure 5, mobile cutter hub 2, the top setting of the mobile cutter hub 2 are provided in the T-slot 11
There is cutting edge, inverted T-block 21, and the horizontal part of the T-block 21 and institute are provided on the lower face of the mobile cutter hub 2
The horizontal part for stating T-slot 11 matches, and can be slided up and down along the horizontal part of the T-slot 11, i.e. the edge or so of the T-block 21
The length in direction is equal to the length in left-right direction of the T-slot 11.
