Abstract
The utility model relates to a double-power roller coal mining machine, wherein a wind road roller motor is horizontally arranged in a horizontal wind road; a machine road roller motor is horizontally arranged in a horizontal machine road under the wind road; the output end of the wind road roller motor is connected with a first rotating rod through a flexible connecting structure, and the output end of the machine road roller motor is connected with a second rotating rod through the flexible connecting structure; the first rotating rod and the second rotating rod are respectively fixed in the wind road and the machine road through movable supports; a plurality of rollers are connected between the first and the second rotating rods through the flexible connecting structures; coal cutters which are distributed spirally along the axial direction of the rollers are fixed on the rollers; and the coal cutters are pressed on a coal mining surface between the wind road and the machine road. In the machine, the wind road roller motor and the machine road roller motor work simultaneously to drive the rollers to rotate, the coal cutters cut the coal, slots are formed at positions through which the rollers pass, the coal wall self-collapses because of the vibration of the rollers under the pressure of a mine, so that working efficiency is high and the recovery rate is high.
Description
Technical field
The utility model 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.
The utility model content
For addressing the above problem, the utility model provides a kind of high efficiency, coal mining machine with double-power rollers that the rate of extraction is high.
The utility model coal mining machine with double-power rollers; 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 dwang by flexible connecting structure; The output of described machine lane Rolling motor is connected with second dwang by flexible connecting structure; Described first dwang and described second dwang be fixed in the described air way by travel(l)ing rest 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.
The utility model coal mining machine with double-power rollers, wherein: described drum length is 0.5～10m.
The utility model coal mining machine with double-power rollers, wherein: described flexible connecting structure is universal drive shaft or cross coupler.
The utility model coal mining machine with double-power rollers air way Rolling motor and machine lane Rolling motor turn round simultaneously, the rotation of drive cylinder, the broken coal cutter breaks coal, cylinder institute forms groove through the position, 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 the utility model coal mining machine with double-power rollers.
The specific embodiment
Below in conjunction with Figure of description the utility model coal mining machine with double-power rollers is described further.
Referring to Fig. 1, the utility model coal mining machine with double-power rollers, 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 the utility model coal mining machine with double-power rollers 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 utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
