Description
Technical field
The present invention relates to a kind of girdles to bore plane formula cutting coal method, and especially a kind of brill plane formula coalcutter planer head is especially suitable
Fast Algorithm for Mining for underground coal mine girdle.
Background technique
China's girdle rich reserves, are widely distributed.National coal mine girdle reserves have more than 60 hundred million tons, and yield is only
There is the 10.4% of total output.Over time, middle thick and high seam resource will peter out, and the exploitation of girdle will become
The trend of one certainty.
Currently, the equipment of domestic more common thin seam mining mainly includes coal plough and brill formula coalcutter.But it passes
The coal plough and coal drilling machine of system are chiefly used in that seam hardness is smaller, seam mining of developmental joint fissure.It is big for seam hardness, section
The seam mining of crack agensis is managed, the exploitation rate of coal plough is slower, and tool wear is serious；The exploitation speed of brill formula coalcutter
Rate is slow, and because of the lower easy bit freezing of revolving speed, it is also possible to drilling tool sideslip occurs.Various reasons all make the production efficiency of girdle
It substantially reduces.
Coal plough for underground coal mine thin seam mining is more demanding to coal mining geological condition, the plane of traditional coal plough
Head is bilateral symmetry, and for the intensity for guaranteeing shaping tool, intercept is wider.During shearing, located horizontally from the emitter two
For side planing cutting knife tool always in same plane planing coal wall, planing pattern is plane cutting, high in exploitation toughness, joint agensis
When coal seam, coal body is not easy avalanche, and raised coal ridge has been retained between adjacent kerf, and coal wall shows the kerf arrangement of W-shaped state, digging
During coal power blader cuts coal wall, planer head needs to overcome biggish ploughing resistance, shaping tool serious wear.
Existing is a kind of coal planer plough that reciprocating and staggered planing can be achieved, including plane body, shaping tool；It is symmetrical for digging body
Structure, the planing sword of shaping tool are bias structure, are mounted on the planing sword of the shaping tool in plane body two sides tool apron in staggeredly
Arrangement；Or plane body is unsymmetric structure, arranged on left and right sides tool apron interlaced arrangement.The technology is small with respect to intercept, the planing that planer head is subject to
Resistance is small, and the adaptability of the coals quality condition such as avalanche high to toughness, difficult, coal bed joints agensis is high.But in actual application process,
Since coal body is an entirety, intensity is very big, so ploughing resistance suffered by planer head is still larger, so as to cause shaping tool institute
The shearing force received is larger, and tool wear is still more serious；Also, since ploughing resistance is larger, lead to the traction power of coal plough
It is higher.Furthermore since ploughing resistance is larger, often there is haulage chain fracture, so the intensity requirement to haulage chain is higher.
Summary of the invention
In order to overcome the above-mentioned deficiency of the prior art, the present invention provides a kind of brill plane formula coalcutter planer head, and this method can
The production efficiency of girdle is greatly improved, can efficiently solve that seam hardness is big, thin seam mining problem of joint agensis,
It is applied widely.
The technical solution used to solve the technical problems of the present invention is that: including device of shearing, the shearing device includes plane
Cutting knife tool, tool apron and plane body, plane body are unsymmetric structure, and the tool apron interlaced arrangement of the left and right sides further includes boring device for coal, described
Bore device for coal include four flame-proof electric motors and four tapered burs, flame-proof electric motor be located at plane in vivo, output end directly with cone
Shape, which is bored, to be connected, tapered bur interlaced arrangement at left and right sides of plane body；Tapered bur is in tilted layout in the horizontal plane, keeps brill device for coal advanced
Device of shearing bores coal.
The utility model has the advantages that mainly there are two core points by the present invention: first, coal plough and brill formula coalcutter are combined by the present invention
One, realizes the innovation in structure；Second, bore device for coal shear in advance device bore coal, for shearing device provide more
The effective scope of freedom greatly reduces ploughing resistance suffered by ramming head, specifically has the beneficial effect that:
1. complete coal body is become broken body, coal strength greatly reduces；
2., to reduce shearing force suffered by shaping tool, reducing shaping tool since coal strength substantially reduces
Abrasion, extend the service life of shaping tool；
3. since coal strength substantially reduces, to reduce the power of coal plough；
4. the intensity requirement of pair haulage chain is lower, chain rupture is reduced, to improve whole coal cutting speed and efficiency；
5. improving the lump coal rate artificially controlled, economic benefit is greatly improved.
