Fig. 1 is the schematic diagram of the utility model embodiment shield machine.
Fig. 2 is the schematic diagram of the utility model embodiment cutter.
Fig. 3 is the exploded view of the utility model embodiment shield cutter.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to Figure 3, the present embodiment shield machine comprises shield body 1 and cutterhead 2, and described shield body 1 is cylindrical, and described cutterhead 2 is arranged on shield body 1 front end, pulverizes earth when cutterhead 2 is for excavating.Described cutterhead 2 comprises top part 21, connecting portion 22 and edge part 23, and described top part 21 is arranged in the middle part of cutterhead 2, and described connecting portion 22 connects top part 21 and edge part 23 respectively.Described top part 21 is provided with drill bit 3, and drill bit 3 is arranged on top part 21 central authorities, and in the present embodiment, drill bit 3 is triangle.Hole can be formed in excavation place by drill bit 3.The side of described connecting portion 22 and edge part 23 is provided with scraper 4, and described edge part 23 surface is provided with cutter 5.Described edge part 23 surface is provided with holder 231, and cutter 5 is fixed on edge part 23 by holder 231.Described cutter 5 comprises main body 51 and multiple accommodation section, and described accommodation section is provided with cutting portion.Described main body 51 is provided with lug boss 52, and described accommodation section is arranged on lug boss 52 both sides respectively.By the cutting portion of main body 51 both sides, cutterhead both direction is rotated all can effectively excavate; In addition, protected by lug boss 52 pairs of main bodys 51, prevent its Fast Wearing.
As shown in Figure 1 to Figure 3, further, described accommodation section comprises horizontal holding part 53 and vertical holding part 54, and horizontal holding part 53 is orthogonal with vertical holding part 54, and described lug boss 52 both sides are relatively set with horizontal holding part 53 and vertical holding part 54 respectively.Described cutting portion comprises the first cutting portion 55 and the second cutting portion 56, first cutting portion 55 is arranged on horizontal holding part 53, and the second cutting portion 56 is arranged on vertical holding part 54, and described first cutting portion 55 is vertical with the second cutting portion 56.By arranging first, second cutting portion 55,56 in different azimuth, cutter 5 can be cut in multiple directions, thus be conducive to improving digging efficiency.In the present embodiment, described first cutting portion 55 is trapezoidal, and the second cutting portion 56 is strip.Described main body 51 comprises surface element 511 and side surface part 512, and described lug boss 52 extends to side surface part 512 by surface element 511, thus has wider protective effect to main body 51.
The shield machine of the present embodiment by cutter multiple cutting portion is set, cutterhead all effectively can be cut in different rotary direction, thus is conducive to accelerating digging operation; Meanwhile, cutter can be protected not by Fast Wearing by lug boss, be conducive to improving cutter life.
It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
