Abstract
The invention discloses a lump coal cutter capable of mining lump coal under the condition that coal in a coal bed is the lump coal. Both the upper cutting part and the lower cutting part of the lump coal cutter are connected with a motor and a speed reducer, and the speed reducer is connected with rollers. The lateral cutting part of the lump coal cutter is connected with a motor and a speed reducer, the speed reducer is connected with a cutting disk, and a thrust disk is connected with the end of the speed reducer. When the cutting parts of the lump coal cutter cut the coal bed, (1) the roller of the upper cutting part of the lump coal cutter cuts the upside (namely coal mining working face) of the coal bed; (2) the roller of the lower cutting part of the lump coal cutter cuts the underside (namely coal mining working face) of the coal bed; (3) the cutting disk of the lateral cutting part of the lump coal cutter cuts the inner lateral surface (namely coal mining working face) of the coal bed; and meanwhile, the thrust disk on the end face of the speed reducer generates an outward (namely coal mining working face) thrust, the outward thrust is acted on the middle uncut coal bed (only one surface of the middle uncut coal bed is connected with the coal bed at the moment), and the coal bed drops.
Description
One, technical field: the present invention relates to the cutting means in coal seam, especially: when the coal seam is bulk, cut goes out the lump coal tapping machine of lump coal.
Two, background technology: 1, present, domestic coal seam cut mainly is that coal-winning machine carries out, coal-winning machine branch: four kinds of sawing formula, planing pattern, drilling formula and milling formulas: 1. sawing formula coal-winning machine, it is coalcutter, go deep into the rib coal cutting by the pick on the cutter chain that is installed in shuttling movement, cut produces coal and is broken coal; 2. the planing pattern coal-winning machine breaks coal by the reciprocating motion planing of planing tool, breaks to cut to produce coal to be broken coal; 3. drilling formula coal-winning machine leans on the cutter tooth of drill margin to pierce coal body, and the coal body fragmentation of the broken coal cutter tooth at drill bit middle part with the middle part arranged, and the coal that drilling goes out is a broken coal; 4. milling formula coal-winning machine, the cutting units of milling formula coal-winning machine: the combined mechanism that is exactly motor, planetary reducer, cylinder.Motor and planetary reducer connection, planetary reducer and cylinder connect.Motor rotation, rotating speed are after planetary reducer slows down, and planetary reducer drives the cylinder rotation, and the cylinder rotation drives pick rotation milling, cut coal, the broken coal on the cylinder.Milling formula coal-winning machine, it is wide, applied widely to distribute at home.Pick rotation milling on the cutting units cylinder of coal-winning machine, cut coal, broken coal, the coal of extraction is broken coal.Because of the cutting units cylinder of coal-winning machine when the cut coal seam: be all cut face cuts, broken coal, the coal in the coal seam is under the block situation, behind this cut, is broken coal.So coal-winning machine can't extraction lump coal.
2, energy consumption height, because of the cutting units diameter of cylinder of coal-winning machine is big, when the cut coal seam, the cut area big (because of the cutting units diameter of cylinder is big, during consistent length.), so load is big, cutting resistance is big, thus the power consumption height, the energy consumption height.
Three, summary of the invention: 1, can't the fast coal of extraction in order to overcome coal-winning machine, the invention provides a kind of lump coal tapping machine, this lump coal tapping machine can not only be mined, and the lump coal tapping machine at the coal in the coal seam is under the block situation, can extraction lump coal.
The technical solution adopted for the present invention to solve the technical problems is: the last cutting units of lump coal tapping machine: the combined mechanism that is exactly motor, reductor, cylinder.Motor and reductor connection, reductor and cylinder connect.The following cutting units of lump coal tapping machine: the combined mechanism that is exactly motor, reductor, cylinder.Motor and reductor connection, reductor and cylinder connect.The side cutting units of lump coal tapping machine: the combined mechanism that is exactly motor, reductor, cutting disc, thrust disc.Motor and reductor connection, reductor and cutting disc connect, and thrust disc and reductor end connect.The cutting units of lump coal tapping machine is when the cut coal seam: the 1. last cutting units of lump coal tapping machine: motor rotation, rotating speed are after reductor slows down, reductor drives the cylinder rotation, and the cylinder rotation drives the pick rotation on the cylinder, top (the referring to coal-face) in cut coal seam; 2. the following cutting units of lump coal tapping machine: motor rotation, rotating speed are after reductor slows down, and reductor drives the cylinder rotation, and the cylinder rotation drives the pick rotation on the cylinder, following (the referring to coal-face) in cut coal seam; 3. the side cutting units of lump coal tapping machine: motor rotation, rotating speed are after reductor slows down, and reductor drives the cutting disc rotation, and the cutting disc rotation drives the pick rotation on the cutting disc, the medial surface (referring to coal-face) in cut coal seam; 4. the side cutting units cutting disc of lump coal tapping machine, the medial surface in the cut coal seam thrust disc when (referring to coal-face), on the reductor end face produce outside (referring to coal-face) thrust, an outward thrust act in the middle of not on the coal seam of cut (in the middle of this moment not the coal seam of cut have only simultaneously be connected) with the coal seam, the coal seam comes off.Coal in the coal seam is under the block situation, and behind this cut, the middle not coal seam of cut all remains fast shape.So lump coal is tapped function extraction lump coal.
2, the beneficial effect of lump coal tapping machine of the present invention is:
1. energy consumption is low, the upper and lower cutting units diameter of cylinder of lump coal tapping machine little (during consistent length), when the cut coal seam, above and below the cut area little, so load is little, cutting resistance is little, so power consumption is little, energy consumption is low.When (referring to coal-face), though the big cutting disc thin thickness of cutting disc diameter, so the cut area is little, load is little at the medial surface in cut coal seam for the side cutting units cutting disc of lump coal tapping machine, and cutting resistance is little, and power consumption is little, and energy consumption is low.Because upper and lower, the interior survey face in coal seam is cut all, middle coal seam not cut partly has only one side to be connected with the coal seam, only need little outside (referring to coal-face) thrust (outward thrust acts on the coal seam of middle not cut), the coal seam of middle cut part is promptly not tear-away.Comprehensive what time above, energy consumption is low.
2. economic benefit height, domestic industry and common people's wilderness demand lumped coal are about 2 times of broken coal prices in lumped coal price on the market at present, economic benefit is huge.
