Description
Technical field
Plane formula cutting coal method is bored the present invention relates to a kind of girdle, it is particularly a kind of to bore plane formula coal-winning machine planer head, especially fit
Fast Algorithm for Mining for underground coal mine girdle.
Background technology
China's girdle rich reserves, are widely distributed.National colliery girdle reserves have more than 60 hundred million tons, and yield is only
Have the 10.4% of total output.Over time, middle thick and high seam resource will peter out, and the exploitation of girdle will turn into
The trend of one certainty.
At present, the equipment of the domestic thin seam mining more commonly used mainly includes coal plough and bores formula coal-winning machine.But, pass
The coal plough and coal drilling machine of system are used for that seam hardness is smaller, developmental joint fissure seam mining.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 coal-winning machine
Rate is slow, and because of the relatively low easy bit freezing of rotating speed, it is also possible to there is drilling tool sideslip.Various reasons all cause the production efficiency of girdle
Substantially reduce.
Coal plough for underground coal mine thin seam mining requires coal mining geological condition the plane of higher, traditional coal plough
Head is bilateral symmetry, and to ensure the intensity of shaping tool, intercept is wider.During shearing, located horizontally from the emitter two
Side planing cutting knife tool is all the time in same plane planing rib, and planing pattern is plane cut, high in exploitation toughness, joint agensis
During coal seam, coal body is difficult avalanche, raised coal ridge has been retained between adjacent kerf, rib shows the kerf arrangement of W forms, in plane
Coal power blader is cut during rib, and planer head needs to overcome larger ploughing resistance, shaping tool serious wear.
Existing is a kind of coal planer plough that reciprocating and staggered planing can be achieved, including digs body, shaping tool；It is symmetrical to dig body
Structure, the planing sword of shaping tool is bias structure, and the planing sword of the shaping tool in the tool rest of plane body both sides is in staggeredly
Arrangement；Or plane body is unsymmetric structure, arranged on left and right sides tool rest 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 ature of coal condition such as high to toughness, difficult avalanche, coal bed joints agensis is high.But in actual application process,
Because coal body is an entirety, intensity is very big, so the 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, because ploughing resistance is larger, cause the traction power of coal plough
It is higher.Furthermore, because ploughing resistance is larger, often there is haulage chain fracture, so the intensity requirement to haulage chain is higher.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, the present invention provides a kind of brill plane formula coal-winning machine planer head, and this method can
The production efficiency of girdle is greatly improved, can efficiently solve that seam hardness is big, the thin seam mining problem of joint agensis,
It is applied widely.
The present invention solve its technical problem use technical scheme be：Including shearing device, the shearing device includes plane
Cutting knife tool, tool rest and plane body, plane body be unsymmetric structure, the tool rest interlaced arrangement of the left and right sides, in addition to brill device for coal, it is described
Boring device for coal includes four flame-proof electric motors and four tapered burs, and it is internal that flame-proof electric motor is located at plane, its output end directly with cone
Shape, which is bored, to be connected, and tapered bur is in plane body left and right sides interlaced arrangement；Tapered bur is in tilted layout in the horizontal plane, makes brill device for coal advanced
Device of shearing bores coal.
Beneficial effect：The present invention mainly has two core points：First, coal plough and brill formula coal-winning machine are combined into 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 it is more
The effective scope of freedom, greatly reduces the ploughing resistance suffered by ramming head, specifically has the beneficial effect that：
1. complete coal body is become into broken body, coal strength greatly reduces；
2. because coal strength is substantially reduced, so as to reduce the shearing force suffered by shaping tool, reduce shaping tool
Abrasion, extend the service life of shaping tool；
3. because coal strength is substantially reduced, so as to reduce the power of coal plough；
4. the intensity requirement of pair haulage chain is relatively low, chain rupture is reduced, so as to improve overall coal cutting speed and efficiency；
5. improving the lump coal rate of manual control, economic benefit is greatly improved.
