Abstract
The invention relates to a coal plough for mining a thin coal layer under a coal mine, and in particular relates to an offset type cutter for a plough head. In the coal ploughing process of a conventional plough head, cutters at the same horizontal positions on two sides are used for performing reciprocating ploughing on coal walls at the same horizontal position all the time, so that under a condition that a coal layer is relatively high in toughness and is provided with non-developed layer joints, coal bodies are extremely unlikely to collapse, protruded coal ridges are retained on the coal walls, and further the plough head needs to overcome relatively high resistance and relatively high impact load and is severely abraded in the running process. The offset type cutter for the plough head of the coal plough comprises a cutter body, an umbrella cap type cutting pick and a cylindrical cutting pick, wherein the centers of the cutting picks and the center of a cutter shank of the cutter body are oppositely offset; the upper half part of the umbrella cap type cutting pick is of an umbrella cap type conical structure, and the lower half part of the umbrella cap type cutting pick is of a cylinder structure of which the diameter is smaller than that of an umbrella edge. According to the coal plough head, the difficulty in ploughing, caused by coal ridge residues, can be effectively solved and the problems of severe abrasion, cutting pick falling and the like of the ploughing cutter are solved; the service life of the ploughing cutter is prolonged, and the coal ploughing efficiency is improved.
Description
Technical field
The present invention relates to the coal plough technical field for thin seam mining under coal mine, specifically a kind of offset cutter and coal plough for planer head.
Background technology
Under coal mine, the coal plough of thin seam mining splits that to adopt Geological Condition Requirement higher, and the cutter that the planer head of traditional coal plough is used is symmetrical structure, and in shearing process, the both sides shaping tool of par position is reciprocal planing rib on same level position all the time.Higher in toughness, under the obsolete coal seam conditions of bedded joint, coal body is extremely difficult for avalanche, rib between adjacent shaping tool remains protruding coal ridge, cause in planer head running and need to overcome larger resistance, shaping tool bears larger impact load, planing difficulty, tool wear is serious, and pick comes off and causes tool failure.By reducing intercept, can solve coal ridge residue problem, but can cause the intensity of shaping tool to decline, can not meet again the demand of planing to cutter intensity.
Summary of the invention
The object of this invention is to provide a kind of offset cutter for planer head, the planing difficulty that the residual coal ridge producing in planing rib process with solution planer head causes, the problems such as shaping tool serious wear, pick come off, improve the application life of shaping tool and the efficiency of shearing.
The technical solution used in the present invention is: a kind of offset cutter for planer head, comprises cutter hub 1, umbrella hat type pick 2 and column type pick 3.
Cutter hub 1 is offset unsymmetric structure, cutter head body center P and relative biasing of cutter hub shank center M, and upper surface N is provided with pick hole I, II, and center, pick hole overlaps with cutter head body center P;
Umbrella hat type pick 2 adopts carbide alloy material, and the first half is symmetrical expression umbrella crown shape conical structure, and cone angle is α, and umbrella is L along segment thickness
3, the latter half is that diameter is less than umbrella along the column structure of diameter;
Described umbrella hat type pick 2 and column type pick 3 are embedded in respectively in pick hole I, the II of described cutter hub 1, adopt soldering to fix.
The offset or dish L of the described relative cutter hub shank center M of cutter hub 1 head center P
1for cutter hub thickness L
41/8～3/8.
Described umbrella hat type pick (2) cone angle scope is 50 °～80 °, and umbrella is along thickness 1mm≤L
3≤ 3mm.
The described crown that is embedded in the column type pick 3 on cutter cutter hub 1 and the difference in height L of umbrella hat type pick 2 crowns
2be 2～5mm.
A coal plough, comprises planer head, characterized by further comprising the offset cutter on the be arranged on planer head described in as above any one.
Advantage of the present invention is: cutter hub is offset dissymmetrical structure, in coal plough uplink and downlink operations planing process on rib formed plane line relativity shift, the shaping tool of planer head one side all the time in opposite side shaping tool shearing process residual coal ridge position plane, cutter planing mode becomes staggered cut from original sealing cut, and the stressing conditions of shaping tool is well improved.Umbrella hat type cutting tooth structure, when having guaranteed the bonding area of pick and cutter hub, has increased the outer wall thickness of cutter hub pick hole I.Umbrella can be protected cutter hub preferably along structure.Column type pick 3 is embedded in the pick hole II of cutter hub 1 upper surface; both protected the upper surface of cutter hub; in planing process, cutter can bear larger stress and impact load again, has reduced the probability that alloy pick comes off, and has improved application life and the shearing efficiency of shaping tool.

The specific embodiment
As shown in Fig. 1～4, comprise cutter hub 1, umbrella hat type pick 2 and column type pick 3; Cutter hub 1 is offset dissymmetrical structure, cutter head body center P and relative biasing of cutter hub shank center M, and upper surface N is provided with pick hole I, II, and center, pick hole overlaps with head center P, the offset or dish L of the described relative cutter hub shank center M of cutter hub 1 head center P
1for cutter hub thickness L
41/8～3/8.
Umbrella hat type pick 2 and column type pick 3 are embedded in respectively in pick hole I, the II of described cutter hub 1 setting, adopt soldering to fix.Umbrella cap-like structure, when having guaranteed the bonding area of pick and cutter hub, has increased the outer wall thickness of cutter hub pick hole I, has effectively reduced the probability that alloy pick comes off, and the umbrella of umbrella hat type pick 2 designs can be protected cutter hub preferably along structure.
The difference in height L of the crown of the column type pick 3 on the cutter hub 1 of described shaping tool and umbrella hat type pick 2 crowns
2be 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 has kept original intensity.But because the head of shaping tool is offset structure, make the head of planer head both sides par position knives be staggered, and then make coal plough uplink and downlink planings formed plane line relativity shift on rib, the shaping tool of planer head one side all the time in opposite side shaping tool shearing process residual coal ridge position plane, cutter planing mode becomes staggered cut from original sealing cut.Like this rib is back and forth planed, can effectively solve the problems such as coal ridge planing difficulty, shaping tool serious wear, pick residual and that cause come off, improved application life and the shearing efficiency of shaping tool.
A coal plough, comprises planer head, characterized by further comprising the offset cutter on the be arranged on planer head described in as above any one.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give all embodiments exhaustive.Every still row in protection scope of the present invention of apparent variation that technical scheme of the present invention extends out or change that belong to.
