Hole hole line is longer, in the biggish situation of buried depth, and with shield machine construction more economical rationality, shield machine is be unable to do without in use
The use of cutterhead, but serrated knife of the existing cutterhead due to being only provided with single structure, cause the driving speed of shield machine slow, construct
Inefficiency does not meet enterprise's number one, for this purpose, it is proposed that a kind of small serrated knife of shield machine.
Utility model content
The purpose of this utility model is to provide a kind of small serrated knives of shield machine, have the high advantage of construction efficiency, solve
Serrated knife of the existing cutterhead due to being only provided with single structure, causes the driving speed of shield machine slow, construction efficiency is low, no
The problem of meeting enterprise's number one.
To achieve the above object, the utility model provides the following technical solutions: a kind of shield machine small serrated knife, including knife
Seat, the second mounting hole, preformed groove, card slot, the first mounting hole, the first serrated knife, the second serrated knife and third serrated knife, the tool apron left side
Middle-end offer preformed groove, and the inner surface of preformed groove offers card slot, the inner surface of the tool apron and is located at preformed groove
Outside offers the first mounting hole, the inner surface of the tool apron and bottom for being located at the first mounting hole offers the second mounting hole,
The right side of the tool apron is fixedly connected sequentially from top to bottom the first serrated knife, the second serrated knife and third serrated knife.
Preferably, the preformed groove is concave structure.
Preferably, the aperture of first mounting hole is two to three times of the second mounting hole aperture.
Preferably, first serrated knife is hemispherical dome structure, and the second serrated knife and third serrated knife are triangular structure, and the
The size of three serrated knives is one. two to one point 5 times of the second serrated knife size.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model the right side of tool apron be fixedly connected sequentially from top to bottom hemispherical dome structure the first serrated knife with
And the second serrated knife and third serrated knife of triangular structure, the stock-removing efficiency of this cutter can be effectively improved, solves existing cutterhead
Due to being only provided with the serrated knife of single structure, cause the driving speed of shield machine slow, construction efficiency is low, does not meet enterprise itself
The problem of interests.
2, middle-end of the utility model on the left of tool apron has opened up the preformed groove of concave structure, and passes through card slot, the first peace
The effect for filling hole and the second mounting hole, can be improved the fastness installed between this tool apron and cutterhead, bring pole for the use of people
Big convenience.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 tool apron, 2 second mounting holes, 3 preformed grooves, 4 card slots, 5 first mounting holes, 6 first serrated knives, 7 second serrated knives,
8 third serrated knives.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, a kind of small serrated knife of shield machine, including tool apron 1, the second mounting hole 2, preformed groove 3, card slot 4, first
The middle-end of mounting hole 5, the first serrated knife 6, the second serrated knife 7 and third serrated knife 8,1 left side of tool apron offers preformed groove 3, and preformed groove 3 is
Concave structure, and the inner surface of preformed groove 3 offers card slot 4, the inner surface of the tool apron 1 and outside for being located at preformed groove 3 offers
