Abstract
The utility model relates to a steeply sloping seam coal mining machine which belongs to coal mining machines conducting mechanized coal mining. The steeply sloping seam coal mining machine comprises a track running mechanism which is provided with an electric control chamber on a frame and is driven by a power machine; a rotor plate which is arranged on the frame and is driven by a motor; a rocking arm which is hinged on the frame fixedly connected with the rotor plate and is provided with a telescopic cylinder; a cutter head which is arranged at the head part of the rotor plate and is driven by the motor; two symmetric rocking arm lifting cylinders which are arranged on the two sides of the rocking arm respectively; a conveying mechanism which is arranged below the inner-side frame of symmetric running tracks; a scraper bucket is arranged in the front of the running tracks; and a left and a right pawls which are symmetrically arranged on the surface of the scraper bucket and are driven by the motor. The outlet end of the scraper bucket is connected with the feed end of the conveying mechanism. The steeply sloping seam coal mining machine realizes steeply sloping seam mechanized coal mining, improves working environment, realizes safe production, and improves the single production yield and recovery ratio of the working face.
Description
Technical field
The utility model belongs to the coal-winning machine of mechanical coal mining, particularly steep seam mining machinery.
Background technology
At present, what the use of mining was more is double-ended shearer, is made up of cutting units, tractive unit, servicing unit and electric fixtures.Cutting units is for to be provided with front roll and back roll respectively at the two ends of frame.During double-ended shearer work, the cylinder in motion the place ahead cuts the top coal, and back roll cuts floor coal.Coal-winning machine is then opposite " to climb base plate ", and its front roll cuts floor coal, and back roll cuts the top coal.After having cut the work plane total length, need the upper-lower position of transposing cylinder, and, carry out rightabout coal cutting stroke then 180 ° of spillplate upsets.This coal-winning machine once advances a cutter along the work plane traction, and the coal cutting mode of advancing a cutter when returning again is called two-way coal cutting.But all coal-winning machines that use both at home and abroad all are that side direction is mined at present.The coal-winning machine traffic direction is vertical with the advance of the face direction during coal mining.And ride over the coal-winning machine of working on the conveyer, when seam inclination just has the danger of downslide during greater than 15 °.Particularly during the up work of chain hauled shearer, in case the major accident that chain rupture will cause machine to glide.If utilize existing coal-winning machine exploitation half-edge coal seam, cutting units will become the fulcrum of coal-winning machine gravity, the coal-winning machine coal mining of can't walking.
Owing to be not applicable to the coal-winning machine of half-edge coal seam, make the mechanization degree of exploitation half-edge coal seam low, single face output is low, and the rate of extraction is low, work under bad environment, vicious behaviour accident pilosity can not guarantee safety in production.
Summary of the invention
The purpose of this utility model is to provide a kind of steep seam mining machinery, can realize the mechanical mining of half-edge coal seam, improves working environment, realizes safety in production, improves the single face output rate and the rate of extraction.
The purpose of this utility model is achieved in that a kind of steep seam mining machinery, be included in the creeper undercarriage that electrical control panel is installed on the support and drives by engine, electric motor driven rotating disk is being set on support, affixed frame on rotating disk, the articulated rocking arm that has telescopic oil cylinder on frame, head at rocking arm is installed with by electric motor driven cutterhead, the rocking arm hoist cylinder of symmetry is installed respectively in the rocking arm both sides; the afterbody of rocking arm hoist cylinder is hinged on the frame; its piston rod end is hinged on the rocking arm respectively; the below that is positioned at the inboard support of traveling crawler of symmetry is installed with conveying mechanism; the place ahead at traveling crawler is installed with scraper bowl; the left side of electric motor driven symmetry is installed; right rake claw on scraper bowl, and the scraper bowl rear portion is connected with the feed end of conveying mechanism.
The utility model coal-winning machine cutterhead is realized feed by telescopic oil cylinder, realize that by the rocking arm hoist cylinder rocking arm drives the upper and lower mobile coal mining of coal-winning machine cutterhead, drive rocking arm by rotating disk, realize that rocking arm swings and rear portion start nest (during the triangle coal mining of top) is mined.Realize along the pseudo-tiltedly upper and lower walking of (26-30 °) work plane by creeper undercarriage.Adopt the coal body that falls and shoveled, harrow into conveying mechanism by left and right rake pawl and be transported to the coal-winning machine rear portion, be transported to the coal body at coal-winning machine rear portion, slip to milling coal hole, in the entrucking outward transport of transportation lane along chute by scraper bowl.Work plane arranges that by pseudo-tiltedly 26-30 ° of angle exploitation band height is 0.8m, and wide is coal seam thickness.Working section recovery can reach more than 80%, and single face output can reach more than the 500kt/a.The utility model has been realized the half-edge coal seam mechanical mining, has improved working environment, has realized safety in production, has improved the single face output rate and the rate of extraction.
Description of drawings
