Abstract
The invention relates to a coal mining machine with double-power rollers. An air gate roller motor is horizontally arranged in a horizontal air gate, a machine gate roller motor is horizontally arranged in a horizontal machine gate below an air gate, the output end of the air gate roller motor is connected with a first rotation rod by a flexible connection structure, the output end of the machinegate roller motor is connected with a second rotation rod by the flexible connection structure, the first rotation rod and the second rotation rod are respectively fixed in the air gate and the machine gate by a movable bracket, a plurality of rollers are connected between the first rotation rod and the second rotation rod by the flexible connection structure, and a coal crushing knife which is spirally arranged in an axial direction along the rollers is fixed on the rollers and is pressed on a recovery working face between the air gate and the machine gate. In the invention, the air gate roller motor and the machine gate roller motor run simultaneously and drive the rollers to rotate, the coal crushing knife crushes coal, the passing positions of the rollers form slots, and coal walls automatically collapse under the function of mine pressure by combining the vibration of the rollers, thereby the work efficiency is high, and the recovery ratio is high.
Description
Technical field
The present invention relates to a kind of coal-winning machine, particularly a kind of coal mining machine with double-power rollers.
Background technology
Present steeply-inclined seam mining method is the coal saw coal-mining method, the coal saw of work plane generally is made up of the broken coal cutter of two-way coal cutting, 0.5 one group of broken coal cutter of～1.0m, coal saw is connected with haulage cable, and wire rope is walked around directive wheel and linked to each other with winch in the tunnel, makes the saw rope compress rib by winch, do back and forth movement, pull out groove, rib collapses under action of underground voluntarily, then by transporting work plane from slipping.The work plane of coal saw coal-mining method is unmanned, and labor strength is low, but efficient is lower, and the above seam mining difficulty of 1.2m is big, and wire rope is broken easily, and is not easy to repair, and whenever cuts one section coal jewel hole again forward, and to keep coal column, the rate of extraction is low.
Summary of the invention
For addressing the above problem, the invention provides a kind of high efficiency, coal mining machine with double-power rollers that the rate of extraction is high.
Coal mining machine with double-power rollers of the present invention; Wherein: the air way Rolling motor is horizontally disposed in the air way of level; In the machine lane of the horizontally disposed level below air way of machine lane Rolling motor; The output of described air way Rolling motor is connected with first by flexible connecting structure and rotates bar; The output of described machine lane Rolling motor is connected with second by flexible connecting structure and rotates bar; Described first rotate bar and described second rotate bar be fixed in the described air way by movable support respectively and described machine lane in
Be connected with some cylinders by flexible connecting structure between described first dwang and described second dwang, be fixed with on the described cylinder along the broken coal cutter of described drum shaft to screw arrangement, described broken coal cutter is pressed on the stope between described air way and the described machine lane.
Coal mining machine with double-power rollers of the present invention, wherein: described drum length is 0.5～10m.
Coal mining machine with double-power rollers of the present invention, wherein: described flexible connecting structure is universal drive shaft or cross coupler.
Coal mining machine with double-power rollers air way Rolling motor of the present invention and machine lane Rolling motor turn round simultaneously, drive the cylinder rotation, and the broken coal cutter breaks coal, cylinder institute forms groove through the position, and rib is under the effect of mine pressure, in conjunction with the vibrations of cylinder, collapse voluntarily, so high efficiency, rate of extraction height.
Description of drawings
Fig. 1 is the schematic diagram of coal mining machine with double-power rollers of the present invention.
The specific embodiment
Below in conjunction with Figure of description coal mining machine with double-power rollers of the present invention is described further.
Referring to Fig. 1, coal mining machine with double-power rollers of the present invention, wherein: air way Rolling motor 2 horizontal arrangement are in the air way 11 of level, in the machine lane 12 of the level of machine lane Rolling motor 4 horizontal arrangement below air way, air way Rolling motor 2 starts with machine lane Rolling motor 4 closes synchronously, switched in opposite, rotating speed is identical.
The output of air way Rolling motor 2 is connected with first dwang 21 by flexible connecting structure such as universal drive shaft, cross couplers, the output of machine lane Rolling motor 4 is connected with second dwang 41 by flexible connecting structure such as universal drive shaft, cross couplers, first dwang 21 and second dwang 41 are fixed in the air way 11 by travel(l)ing rest 14,15 respectively and in the machine lane 12, travel(l)ing rest is used to adjust first dwang 21 and second dwang, 41 height and horizontal levels.
Be connected with some cylinders 6 by flexible connecting structure such as universal drive shaft, cross couplers between first dwang 21 and second dwang 41, be fixed with the broken coal cutter of arranging along cylinder 6 axial screw 61 on the cylinder 6, broken coal cutter 61 is pressed on the stope 13 between air way 11 and the machine lane 12.Each cylinder 6 length is 0.5～10m.
The course of work of coal mining machine with double-power rollers of the present invention is as follows: air way Rolling motor 2 turns round simultaneously with machine lane Rolling motor 4, drive first dwang 21, second dwang 41, cylinder 6 rotations, broken coal cutter 61 broken coals, cylinder 6 form groove through the position, rib is under the effect of mine pressure, in conjunction with the vibrations of cylinder 6, collapse voluntarily, transport work plane by coal from slipping then, by machine lane conveyer coal is transported again, finish back production.The goaf supporting is same as the prior art, adopts gas to pile up neatly 5 supports, and gas buttress traction electric machine 3 is used for mobile gas buttress 5.
Above embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
