Description
Technical field
A kind of continuous milling machine cutting teeth is the utility model is related to, more particularly to a kind of steel alloy continuous milling machine cutting teeth.
Background technology
The cutting teeth of continuous milling machine refers to the tooth of continuous milling machine cutting coal petrography, and the cutting teeth of continuous milling machine is cast by hard alloy
Form, because coal petrography hardness is larger, the abrasion to cutting teeth is more serious, and pit mining replacing cutting teeth is more difficult, although
Its cost is high（One about 1000 yuans of import cutting teeth）Pit mining can only also use the cutting teeth of this material.Lian Cai
Machine is used for after open pit slope shearer gearhead, and its working environment has occurred that essence changes, and changes cutting teeth and is revealing
Be relatively easy under its environment, thus the material for changing it make its cost reduce be present study the main themes.Together
When, feasible for casting technique, new hard alloy cutting tooth is not sharp enough, and size is also smaller, installation difficulty.
The content of the invention
The purpose of this utility model is to provide a kind of steel alloy continuous milling machine cutting teeth, enough sharp, the chis of steel alloy cutting teeth
It is very little big, easy for installation, low cost.
A kind of steel alloy continuous milling machine cutting teeth, including mounting hole, cylinder, cone, semi-circular groove, it is characterised in that：
The cylinder is the installation portion of cutting teeth, and in the annulus on cylinder insertion roller, one end of cylinder is fixedly mounted on
On the disk of cone, and the diameter of cylinder is less than the disk diameter of cone, and peace is provided with the top of cylinder
Fill hole；The cone is the main body of cutting teeth, is provided with semi-circular groove in the outer surface of cone, wherein semi-circular groove shares three
Bar groove, 120 ° are separated by between groove and groove, wherein the length of semi-circular groove is less than the height of cone, and semi-circular groove passes through circle
The disk of cone.
Further, the mounting hole is a through hole, and cylinder is fixed on to the annulus on roller by mounting hole
In.
Further, the cylinder and cone composition continuous milling machine cutting teeth, and continuous milling machine cutting teeth is cast member, its material
Expect for steel alloy.
The beneficial effects of the utility model are：The utility model is ingenious in design, rational in infrastructure, using steel alloy, to cast
Continuous milling machine cutting teeth is made, makes its cost very low, while the supply of cutting teeth material is not a problem；Cutting of the present utility model
Main body is cone, makes cutting teeth size bigger than original, three semi-circular grooves are provided with cone, make gas in coal seam with
Liquid is discharged by semi-circular groove, reduces resistance of the coal seam to cutting teeth, while also make cutting teeth more sharp；This practicality is new
Type make use of the mounting hole on installation portion cylinder, makes the easier for installation of cutting teeth, has saved the time.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, mounting hole 1, cylinder 2, cone 3, semi-circular groove 4.
Embodiment
It is better embodiment of the present utility model below, but does not therefore limit the scope of protection of the utility model.
As illustrated, a kind of steel alloy continuous milling machine cutting teeth, including mounting hole 1, cylinder 2, cone 3, semi-circular groove
4, it is characterised in that：The cylinder 2 is the installation portion of cutting teeth, and cylinder 2 is inserted in the annulus on roller, cylinder 2
One end be fixedly mounted on the disk of cone 3, and the diameter of cylinder 2 be less than cone 3 disk diameter,
The top of cylinder 2 is provided with mounting hole 1, and wherein mounting hole 1 is a through hole, and is fixed on cylinder 2 by mounting hole 1
In annulus on roller, wherein mounting hole 1 makes the easier for installation of cutting teeth；The cone 3 is the main body of cutting teeth, is increased
The size of big cutting teeth, and the vertex of a cone of cone 3, increase the sharpness of cutting teeth, semi-circular groove are provided with the outer surface of cone 3
4, wherein semi-circular groove 4 shares three bar grooves, and 120 ° are separated by between groove and groove, and the wherein length of semi-circular groove 4 is less than cone 3
Highly, and semi-circular groove 4 passes through the disk of cone 3, and the gas in coal seam and liquid are passed through half by wherein semi-circular groove 4
Circular trough 4 is discharged, and reduces resistance of the coal seam to cutting teeth, while also make cutting teeth more sharp；The cylinder 2 and circular cone
Body 3 forms continuous milling machine cutting teeth, and continuous milling machine cutting teeth is cast member, and its material is steel alloy, and cost is very low.
The utility model devises a kind of steel alloy continuous milling machine cutting teeth, and the utility model is ingenious in design, rational in infrastructure, adopts
With steel alloy, to cast continuous milling machine cutting teeth, make its cost very low, while the supply of cutting teeth material is not a problem；This
The cuts main body of utility model is cone, makes cutting teeth size bigger than original, three semi-circular grooves are provided with cone, are made
Gas and liquid in coal seam are discharged by semi-circular groove, reduce resistance of the coal seam to cutting teeth, while also make cutting teeth more
It is sharp；The utility model make use of the mounting hole on installation portion cylinder, make the easier for installation of cutting teeth, when having saved
Between.
It the above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of the art
Member for, on the premise of the utility model technical principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
