2) relatively poor, the geologic structure relative complex of girdle mine coal seam occurrence condition, existing equipment is difficult to exercise one's ability, and even hinders and produces;
3), because operating environment is narrow and small, cause the supporting complexity of existing equipment, repair and maintenance difficulty;
4) supporting existing equipment disposablely has high input, output is few, and comprehensive benefit is poor.
Coal-winning machine is be accompanied by the popularization of mechanical coal mining and progressively grow up.From common mechanicalization mine develop into generally adopt, high-grade conventional mining, combine adopt, to the high-yield and high-efficiency mine construction of today, along with the minimizing day by day of resource, have to develop low seam mining machinery, the progress of every one-phase is all closely related with the update of coal-winning machine technology.Therefore we need to rely on current existing coal-winning machine technology, develop light and flexible, applicability is strong, production efficiency is high, supporting convenience, power consumption are little, the novel low seam mining machinery of high safety, solve middle-size and small-size mine with this and lack equipment support, be difficult to carry out the pressing problem of High-efficient Production.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned problems of the prior art, and a kind of twin-roll low seam mining machinery is provided, thereby promotes that coal production is safe and efficient carries out smoothly.
The utility model is achieved by the following technical solution:
A kind of twin-roll low seam mining machinery, comprises scrapper conveyor, drive division, cutting part and driving-chain; Drive division is arranged on respectively head and the tail place of scrapper conveyor, drive division comprises driving chain sprocket, shaft coupling, reducer, adapter sleeve, magneto and connection cover, driving chain sprocket is rotatably installed on the lateral wall of scrapper conveyor, driving chain sprocket outer end is connected with reducer by shaft coupling, driving chain sprocket, reducer are supported on the base of scrapper conveyor, connect cover and be arranged on reducer outside, shield, magneto is located at and is connected in cover and be connected with reducer by adapter sleeve; Driving-chain is connected with a joggle on two driving chain sprockets; Cutting part comprises left cutting arm, right cutting arm and skid, left cutting arm right-hand member end and right cutting arm left end end are hinged by bearing pin, bearing pin is articulated with on skid again, skid is slidably mounted on (being that skid can horizontally slip on scrapper conveyor) on scrapper conveyor, and skid is connected (be driving-chain can traction slide frame horizontally slip on scrapper conveyor) with driving-chain; Between left cutting arm right-hand member and right cutting arm left end, two oil cylinders are installed, wherein, first oil cylinder one end is hinged on left cutting arm, the other end is hinged on skid, and second oil cylinder one end is hinged on left cutting arm, the other end is hinged on right cutting arm.
In the time that coal-winning machine starts to mine, the piston rod of the second oil cylinder stretches, and the height that makes right cutting arm be raised to coal mining stops, left cutting arm level, and driving-chain drives skid to move, and starts to mine thereby drive left and right cutting arm to move; In exploitation process, the second cylinder piston rod is motionless, regards a fixed bar as, the piston rod of the first oil cylinder stretches, and makes right cutting arm slowly drop to level, and left cutting arm is raised to the height of mining, driving-chain drives skid to move, thereby drives left and right cutting arm to move beginning back production.
The utility model device has changed electric traction and hydraulic haulage mode in the past, directly drives with magneto, and reducer and drive unit are combined as a whole, and in minimum volume and space, arrange.Also the advantage of the strong point of chain haulage and flitting is combined simultaneously, save numerous and diverse control system, make low seam mining machinery under rugged environment, maintenance is easy, failure rate is low.The utility model device also adopts magneto frame head and tail mode of traction, solves small space Layout Problem.
The utlity model has following beneficial effect:
1) drum drive motor is magneto, and structure is little, and power is large, and frequency conversion system can be placed on scrapper conveyor frame head and tail, and equipment failure rate is low;
2) fuselage is the shortest, and compact conformation is crossed coal space high, adapts to the different base plate fluctuations of thin seam working surface;
3) coal-winning machine automatic monitoring and control technology, guarantees staff's safety.
