Description
Technical field
The present invention relates to a kind of coalcutters that underground coal mine founds layer coal working face.
Background technology
Existing coalcutter is divided by walking manner rides conveyer coalcutter and off pan shearer, by the single rolling of roller number point
Cylinder, two kinds of twin-roll.The cutting mechanism of coalcutter be mounted on fuselage close coal wall one side, direction of propulsion be also along bottom plate to
The direction of coal wall promotes, and coalcutter and conveyer are all along being in tilted layout, and personnel station operates on bottom plate, and the width of cutting mechanism is
The theory of coalcutter is cut deep.In high_dipping face, the anti-fall problem of coalcutter is difficult to solve.Simultaneously as inclination angle is too
Greatly, upper concordant direction tends to have coal cinder and tumbles, and the downward concordant direction of coal cinder the more is rolled the more fast, irresistible, once operating personnel are pounded,
Consequence is serious, either dead or wounded；And operating personnel station operates on the slope of such high inclination-angle, and it is in itself and extremely dangerous, one
Denier is slipped landing, is tumbled than it from hundred meters of high steps more much serious, and consequence is hardly imaginable.So in high-dipping coal
Mechanical mining is realized in layer, is a great problem for perplexing coal-getter author's decades.
Since high_dipping face coal mining is dangerous too big, so half-edge coal seam is arranged that setting up layer works by some places
Face is exploited in a manner that vertical layer is mined, i.e. in operating personnel both sides, coal wall is pushed down in operating personnel underfooting top, bottom plate
Into the mode of coal mining.So the life security of worker is centainly ensured.
But in vertical layer coal working face, coal wall is in the lower section of the foot of coal work personnel, these existing coalcutters
It can not all use.Thus in decades can only big gun adopt coal breakage, there is very big security risk in this, while complete in gas protrusion mine
It manually shovels coal shipment, so labor strength is big, production efficiency is very low, so never a wide range of promote is opened.Some
Colliery also avoids blowing out and causes gas accident to keep high yield, still emits life danger along the high-dipping being in tilted layout
It is mined in working face using traditional coalcutter.
The content of the invention
It not only can be to avoid the working at height under high inclination-angle, but also can realize the technical problem to be solved in the present invention is to provide one kind
The coalcutter that can be used for vertical layer coal working face of mechanical mining.To solve the above-mentioned problems, the present invention includes cutting machine
Structure, fuselage, walking mechanism, it is characterized in that the cutting mechanism of the coalcutter is separately positioned on the close top plate one side of fuselage and close
Bottom plate one side, the close top plate one side and the left and right sides that fuselage length direction is namely arranged on close to bottom plate one side.
A kind of coalcutter as described above, it is characterized in that one cutting mechanism is installed close to the one side of top plate in fuselage,
A cutting mechanism is installed in the one side of the close bottom plate of fuselage, the two cutting mechanisms are separately positioned on the both ends of fuselage.
A kind of coalcutter as described above, it is characterized in that fuselage installs two cutting mechanisms close to top plate one side, the two
Cutting mechanism is separately positioned on the both ends of fuselage；Two cutting mechanisms are installed in the one side of the close bottom plate of fuselage, the two cut
Cutting mill structure is separately positioned on the both ends of fuselage.
A kind of coalcutter as described above, matches somebody with somebody it is characterized in that being equipped on fuselage with the drag conveyor on coal wall
Cover the running gear used.
A kind of coalcutter as described above, it is characterized in that fuselage is equipped with the supporting surface directly slided on coal wall.
A kind of coalcutter as described above, it is characterized in that the cutting mechanism includes rocking arm and roller, in fuselage and cut
The device of rotation axis and coal wall angle between mechanism equipped with adjustable rollers.
A kind of coalcutter as described above, it is characterized in that there is the dress of adjustable cutting mechanism and coal wall angle on coalcutter
It puts.
After such structure, penetraction depth is determined by planted agent's amount, the coal breakage position of coalcutter is become by the one side of fuselage
For the bilateral of fuselage.As fuselage is moved in pseudo- tilted direction, the roller of fuselage both sides cuts the coal wall below coalcutter
Go out twice ditch, and the coal cut is fitted into conveyer by two oppositely oriented rollers and is transported.In the working face of no conveyer
In, slip transporting coal certainly by pseudo- angle of internal friction.Conveyer is promoted a step pitch to top plate direction, coalcutter is close to the roller in top plate direction
Coal cutting.One knife of a knife is continuously cut near top plate like this, and then another one knife of knife cuts bottom plate with the roller of opposite side.In nothing
In the working face of conveyer, it can be oriented to the guide rail separately set to coalcutter, coal breakage method is same as described above.In this way, coal mining scope
Full coal wall can be covered, so that vertical layer working face machine is adopted and be possibly realized.This eliminates vertical layer working face big gun and adopts coal breakage, people
A series of dangerous hidden danger that work is shoveled coal, greatly reduce labor strength, substantially increase yield.
