Abstract
The present invention relates to a kind of coal plough for underground coal mine thin seam mining, specifically a kind of offset cutter for planer head.Traditional planer head is during shearing, both sides cutter located horizontally from the emitter is back and forth planed in same level position to rib all the time, in toughness under the coal seam conditions of higher, bedded joint agensis, coal body pole is difficult avalanche, rib remains raised coal ridge, cause and need to overcome larger resistance and greater impact load, serious wear in planer head running.The present invention provides the handle of a knife center shifted relative of a kind of offset cutter for coal planer plough, including cutter hub, umbrella hat type pick and column type pick, pick center and cutter hub；Umbrella hat type pick top half is umbrella crown shape conical structure, and the latter half is that diameter is less than umbrella cylindrical structure diametrically.The present invention can effectively solve the problem that the problems such as planing caused by coal ridge residual is difficult, and shaping tool serious wear, pick come off, and improve the service life and shearing efficiency of shaping tool.
Description
Technical field
It is specifically a kind of for digging the present invention relates to be used for technical field of coal planers for mining thin coal layers in a coal mine
The offset cutter and coal plough of head.
Background technology
The coal plough of underground coal mine thin seam mining is higher to coal mining geological condition requirement, and the planer head of traditional coal plough is used
Cutter be symmetrical structure, during shearing, both sides shaping tool located horizontally from the emitter is past on same level position all the time
Plane again rib.Higher in toughness, under the coal seam conditions of bedded joint agensis, coal body pole is difficult avalanche, adjacent shaping tool it
Between rib remain raised coal ridge, cause and need to overcome larger resistance, shaping tool to bear larger in planer head running
Impact load, planing is difficult, and tool wear is serious, and pick comes off causes tool failure.Coal ridge can be solved by reducing intercept
Residue problem, but the intensity of shaping tool can be caused to decline, demand of the planing to tool strength can not be met again.
The content of the invention
It is an object of the invention to provide a kind of offset cutter for planer head, to solve planer head during rib of planing
The problems such as planing difficult, shaping tool serious wear, pick come off caused by the residual coal ridge of generation, improves making for shaping tool
With life-span and shearing efficiency.
The technical solution adopted by the present invention is：A kind of offset cutter for planer head, including cutter hub 1, umbrella hat type pick 2
With column type pick 3.
Cutter hub 1 is offset unsymmetric structure, cutter head body center P and cutter hub shank center M shifted relatives, upper surface N
Pick hole I, II are provided with, pick hole center overlaps with cutter head body center P；
Umbrella hat type pick 2 uses hard alloy material, and top half is symmetrical expression umbrella crown shape conical structure, and cone angle is α, umbrella
It is L along segment thickness3, the latter half is that diameter is less than umbrella cylindrical structure diametrically；
Described umbrella hat type pick 2 and column type pick 3 is embedded in pick hole I, II of the cutter hub 1 respectively, uses
Soldering is fixed.
Described offset or dish Ls of the head center P of cutter hub 1 with respect to cutter hub shank center M1It is cutter hub thickness L41/8~3/
8。
Described umbrella hat type pick (2) cone angle scope is 50 °~80 °, and umbrella is along thickness 1mm≤L3≤3mm。
The crown of the described column type pick 3 being embedded on cutter cutter hub 1 and the difference in height L of the crown of umbrella hat type pick 22
It is 2~5mm.
A kind of coal plough, including planer head, it is characterised in that also including on the An Zhuaned planer head described in as above any one
Offset cutter.
It is an advantage of the invention that：Cutter hub is offset dissymmetrical structure, in coal during the operation planing of coal plough uplink and downlink
The relative skew of plane line formed on wall, the shaping tool of planer head side is remained during the shearing of opposite side shaping tool all the time
Coal ridge position planed, cutter planing mode staggeredly cut, the stress feelings of shaping tool are changed into from original closing cut
Condition is improved well.Umbrella hat type cutting tooth structure increases cutter hub while ensure that the bonding area of pick and cutter hub
The outer wall thickness of pick hole I.Umbrella can preferably protect cutter hub along structure.Column type pick 3 is embedded in the pick of the upper surface of cutter hub 1
In the II of hole, the upper surface of cutter hub was both protected, cutter can bear bigger stress and impact load again during planing, reduced
The probability that alloy pick comes off, improves the service life and shearing efficiency of shaping tool.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is the structural side view of coal planer planning cutting knife tool of the present invention；
Fig. 2 is the structural front view of coal planer planning cutting knife tool of the present invention；
Fig. 3 is the structural front view of cutter hub in the present invention；
Fig. 4 is the front view of umbrella hat type pick in the present invention；
In figure：1. cutter hub, 2. umbrella hat type pick, 3. column type pick.
Specific embodiment
As shown in figures 1-4, including cutter hub 1, umbrella hat type pick 2 and column type pick 3；Cutter hub 1 is offset asymmetrical junction
Structure, cutter head body center P and cutter hub shank center M shifted relatives, upper surface N are provided with pick hole I, II, pick hole center and head
Portion center P overlaps, described offset or dish Ls of the head center P of cutter hub 1 with respect to cutter hub shank center M1It is cutter hub thickness L41/8
~3/8.
Umbrella hat type pick 2 and column type pick 3 are embedded in pick hole I, II of the setting of the cutter hub 1 respectively, using pricker
Solid welding is determined.Umbrella cap-like structure increases the outer wall thickness of cutter hub pick hole I while ensure that the bonding area of pick and cutter hub
Degree, effectively reduces the probability that alloy pick comes off, and the umbrella of the design of umbrella hat type pick 2 can preferably protect cutter hub along structure.
The crown of the column type pick 3 on the cutter hub 1 of described shaping tool and the difference in height L of the crown of umbrella hat type pick 22
It is 2~5mm.
Shaping tool provided by the present invention is arranged on planer head both sides, and the intercept of shaping tool does not change, and maintains original
There is intensity.But because the head of shaping tool is offset structure, submit the head of planer head both sides cutter located horizontally from the emitter
Mistake arrangement, and then make the relative skew of the plane line that the planing of coal plough uplink and downlink is formed on rib, the shaping tool of planer head side
All the time the coal ridge position for being remained during the shearing of opposite side shaping tool is planed, and cutter planes mode by original closing
Cut is changed into staggeredly cut.So rib is back and forth planed, planing difficulty, plane caused by coal ridge residual can be effectively solved
The problems such as cutting knife tool serious wear, pick come off, improves the service life and shearing efficiency of shaping tool.
A kind of coal plough, including planer head, it is characterised in that also including on the An Zhuaned planer head described in as above any one
Offset cutter.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.Here all of implementation method cannot be exhaustive.It is every to belong to this hair
Obvious change that bright technical scheme is extended out changes row still in protection scope of the present invention.
