Description
Technical field
The utility model relates to a kind of four-drill auger miner, is particularly useful for the ultra-thin coal seam of 0～25 ° of minimum thickness 0.45m, inclination angle and the exploitation in liberation layer coal seam.
Background technology
Thin, the ultra-thin coal seam of China distributes extensively, reserves are big, and proved reserves account for 20% more than of coal gross reserves, and output only accounts for about 8% of total output, far below the shared ratio of its reserves.Each big mineral bureau of the whole nation all is faced with thin, extremely rich seam mining problem, special along with old mining area thick and medium-thickness seam reserves exhausted day by day, thin, the ultra-thin coal seam mining problem is more outstanding.Take a broad view of national Present of Coal Exploitation, thin, ultra-thin coal seam exploitation has been a problem demanding prompt solution of overall importance.
Technology modes such as the exploitation thin, ultra-thin coal seam of China has at present adopted successively that big gun is adopted, coalcutter cooperates that big gun is adopted, standard machinery coal mining and comprehensive mechanical coal mining, but for the ultra-thin coal seam of thickness less than 0.8m, mechanical mining is very difficult, the exploitation in this part coal seam was once abandoned in some collieries, had caused the huge waste of coal resources.
For these reasons, eighties of last century the nineties China has introduced three drill auger miners from Ukraine.Compare with drum shearer with traditional thin seam mining equipment such as coal plough, three drill auger miners have unique advantage in application.At first, make the ultra-thin coal seam that can't exploit with traditional mining equipment obtain effective exploitation, realized manless working face exploitation truly, greatly improved workman's condition of labor and working environment, safety in production is effectively ensured; Secondly, with the broken coal of traditional process for stoping, coaling, transport five big operations such as coal, supporting and processing and merge, all finished by the drilling tool of the formula of boring coal-winning machine, simplified process for stoping greatly, and work plane chooses and lack, work efficiency height, economic results in society are very remarkable; The 3rd, strong to geological structure compliance, when running into tomography, only need rig is moved to new place, reorientate and get final product drilling; This unit can be used safely in the mine that gas outburst danger, coal dust explosion hazard are arranged simultaneously, has realized the new technology that coal mining, ventilation, water spray carry out simultaneously.But three drill auger miners exist that cut efficient is low, effect of loading coal is poor, connect the time-consuming drawback of drilling rod; And bit diameter is less in the middle of three drill auger miners, the defeated relatively poor and chute blockage of coal effect, and its three drill bits are different, poor, the inconvenient maintenance of interchangeability.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of rational in infrastructure, and cut efficient height, effect of loading coal are good, and interchangeability is strong, four-drill auger miner for ease of maintenaince.
For achieving the above object, four-drill auger miner of the present utility model, comprise that symmetry is located at the fire-proof motor at frame rear portion, fluid-flywheel clutch that links to each other with fire-proof motor and the reducer that connects with the fluid-flywheel clutch flange, fluid-flywheel clutch is provided with the fine setting oil cylinder, reducer is provided with micromatic setting, the front portion of frame is provided with fixed case, the middle part of fixed case is provided with the air duct that links to each other with airduct, be respectively equipped with left-handed drilling rod and dextrorotation drilling rod between fixed case and the symmetrically arranged reducer, be arranged with four drill bits that rotation direction is opposite on the fixed case, four drill bits divide dextrorotation drill bit and left-handed drill bit to be provided with in pairs; Be arranged with one of the transmission that links to each other with the dextrorotation drilling rod and two of the transmissions that links to each other with left-handed drilling rod in the fixed case, transmission one beam warp gear connects the idler shaft that cuts one and left side respectively, connects through the gear of the idler shaft in left side and cuts two; Transmission two beam warp gears connect the idler shaft that cuts four and right side respectively, connect through the gear of the idler shaft on right side and cut three; The gear number of teeth, modulus in the described fixed case on each power transmission shaft are all identical.
Beneficial effect: four-drill auger miner of the present utility model, drill bit are symmetrically arranged, direction of rotation is opposite, drive drill bit movement by gears engaged, finish cut.Cutting mechanism stress balance during coal-winning machine work, complete machine stability is strong.Except that the advantage with three drill auger miners, its specific energy of cutting has reduced nearly 30% than three drill auger miners, and it is nearly 20% that coal capacity has improved, and improved the defeated coal effect in drill bit place, reached and cut effect of loading coal preferably.For exploitation ultra-thin coal seam, liberation layer coal seam provide a kind of coal-winning machine efficiently, can be used in combination with blasting process, open a tunnel less, reduced cost of winning, improve cut efficient, defeated coal effect, coal capacity and be convenient to more bit change, be applicable to the ultra-thin coal seam of 0～25 ° of minimum thickness 0.45m, inclination angle and the exploitation in liberation layer coal seam.Its compact conformation is reasonable, operates steadily, and interchangeability is strong, for ease of maintenaince, has practicality widely.
