The specific embodiment
To combine accompanying drawing that the embodiment of the invention is done to describe in detail further below.
Milled head of the present invention, its preferable specific embodiment is as shown in Figure 1:
The axis part of this milled head is provided with dismounting axis hole 2, and the inner of said dismounting axis hole 2 and outer end are respectively equipped with bearing 3,5; The outer face of said milled head is provided with the fixing threaded hole (not shown).
The diameter of the endoporus of the bearing 5 of said dismounting axis hole 2 outer ends is greater than the diameter of the endoporus of the bearing 3 of said dismounting axis hole 2 the inners.
The outer end of said dismounting axis hole 2 is provided with protective cover 4.
The diameter of this milled head is more than or equal to 400cm, and this milled head is a hollow-core construction.
The diameter of the roller 1 of this milled head is 30cm.
The special-purpose dismounting accessory of above-mentioned milled head of the present invention, its preferable specific embodiment is as shown in Figure 2:
Comprise dismounting axle 8, dismounting arm 9, the lower end of said dismounting arm 9 is fixedly connected with the rear end of said dismounting axle 8, and the endoporus of the bearing in the diameter of said dismounting axle 8 and the said dismounting axis hole adapts;
The rear portion of said dismounting axle 8 is provided with limiting plate 6, and the position corresponding to the fixing threaded hole on the outer face of said milled head on the said limiting plate 6 is provided with through hole.
Said dismounting axle 8 is the step axle, the diameter that said dismounting axle 8 is anterior and the diameter at rear portion respectively with the bearing of the bearing of said dismounting axis hole the inner and outer end to adaptation.
The rear portion of said dismounting axle 8 is provided with draw-in groove, and said limiting plate 6 is a two halves formula structure, and two halves limiting plate 6 snaps into respectively in the said draw-in groove.
