Description
Technical field
Coal production field is the utility model is related to, is specifically related to a kind of coal mining development machine pick.
Background technology
Development machine type is more：It is divided into common loom and rock tunnel(ling) machine by manipulating object；It is divided into open type by operating type
Development machine and shield formula development machine.
Existing development machine pick is mostly conical structure, and surface lacks the cataclasitlc structure of auxiliary, so crushing efficiency
It is not high, Shortcomings, while the sophisticated conehead of pick easily wears, and needs to change whole pick, very waste of materials after abrasion,
A kind of therefore, it is proposed that coal mining development machine pick.
Utility model content
The technical problems to be solved in the utility model is to overcome prior art pick crushing effect undesirable, easily causes wave
A kind of the defects of taking, there is provided coal mining development machine pick.
In order to solve the above technical problems, the utility model provides following technical scheme：A kind of coal mining is cut with development machine
Tooth, including cylinder, torus, frustum, helical edges, triangular prism, conehead and fastening bolt, the left end of the cylinder are coaxially set
There is torus, the left side of the torus is provided with frustum, and the cone of the frustum cuts to form plane, and the lateral wall disk of frustum
Helical edges are installed with, triangular prism, the lateral wall one of the triangular prism and frustum are interval between the helical edges and torus
Body connects, and center opens up circular hole in the cylinder to frustum, and the circular hole bottom is provided with erecting bed, the erecting bed and frustum
It is wholely set, through hole is provided among the erecting bed, runs through in the through hole and is provided with fastening bolt, the fastening bolt is by conehead
It is fixedly connected in the plane of frustum front end.
Further, the cylinder, torus, frustum, helical edges and triangular prism are that an integral material is process.
Further, the blade surface of the helical edges is set to arcwall face.
Further, the material of the conehead is Hardmetal materials.
The utility model has an advantageous effect in that compared with prior art：A kind of coal mining development machine pick,
Helical edges and triangular prism are set up in original pick surface, improve crushing efficiency, meanwhile, original pick tip is improved,
Conehead made of Hardmetal materials is arranged to, substantially increases the hardness and abrasion resistance of conehead, can be more after conehead abrasion
Change conehead, it is not necessary to change whole pick, greatly reduce waste, the utility model is simple in construction, low manufacture cost, using broken
Broken effect is good, practical.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Understood referring to figs. 1 to Fig. 3：A kind of coal mining development machine pick, including cylinder 1, torus 2, frustum 3,
Helical edges 4, triangular prism 5, conehead 8 and fastening bolt 9, the left end of the cylinder 1 are coaxially provided with torus 2, the torus 2
Left side be provided with frustum 3, the cone of the frustum 3 cuts to form plane, and the lateral wall of frustum 3 spirals provided with helical edges 4, institute
State and triangular prism 5 is interval between helical edges 4 and torus 2, the lateral wall integrally connected of the triangular prism 5 and frustum 3 is described
Cylinder 1 to center in frustum 3 opens up circular hole 6, and the bottom of circular hole 6 is provided with erecting bed 7, the erecting bed 7 and the one of frustum 3
Set, through hole is provided among the erecting bed 7, runs through in the through hole and is provided with fastening bolt 9, the fastening bolt 9 is by conehead 8
It is fixedly connected in the plane of the front end of frustum 3.
The cylinder 1, torus 2, frustum 3, helical edges 4 and triangular prism 5 are that an integral material is process, intensity
Height, service life length；The blade surface of the helical edges 4 is set to arcwall face, avoids rapid wear；The material of the conehead 8 is hard
Alloy material, hardness is high, and anti-wear performance is good.
Principle and advantage of the present utility model：During use, conehead 8, helical edges 4 and triangular prism 5 can be accelerated brokenly
Muck wall, after conehead 8 wears, pick is removed from destroyer, then fastening bolt 9 is turned with instrument, pulls down abrasion
Conehead 8, the conehead 8 more renewed, then rotational fastener bolt 9, conehead 8 are fixed in the plane of the front end of frustum 3, are cut in original
Tooth surface sets up helical edges 4 and triangular prism 5, greatly improves crushing efficiency, meanwhile, original pick tip is changed
Enter, be arranged to the conehead 8 of hard alloy material that can be changed, only need to change conehead 8 after the abrasion of conehead 8, be not required to
Pick is entirely changed, greatlys save material, the utility model is simple and reasonable, low manufacture cost, and crushing efficiency is high, fits
Conjunction is promoted the use of.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
