In such scheme, said bottom jib is by cover plate up and down and be arranged on that both sides constitute with the panel that constitutes die cavity between the cover plate, bottom jib can rotate 180 degree to realize coal cutting operating mechanism around output main shaft left-right rotation in the coal cutting work plane under the drive of directive wheel.In order to regulate the tightness of chain, bottom jib is provided with the governor motion of regulating the chain degree of tightness.Governor motion can adopt the bolt governor motion, and is arranged in the die cavity of bottom jib.Be fixed on the sprocket in the cut coal seam on the chain, the sprocket direction is positioned at the chain traffic direction and spends to the cross section of hanging down positive and negative 60.
In such scheme, said coal cutting variable transmission mechanism is the gear graduation transmission mechanism that contains the clutch pair.
In such scheme, said walking haulage gear is by rope sheave, fleet wheel, and an end is fixed in the steel cable that rope sheave, the other end be fixed on the pile of operation the place ahead and constitutes.
In such scheme, said traction variable transmission mechanism is the worm and gear traction variable transmission mechanism that contains the friction plate transmission.
In such scheme, said actuating unit has cooling dustproof motor for design, and walking haulage gear and coal cutting operating mechanism are provided with motor in both sides by same motor-driven.
The utility model has also been taked some other approximate measure.
The coalcutter that the utility model discloses in use, need excavate out in the coal seam and can hold the long trough passage that coalcutter is walked within it, and a column is fixed apart from initialization face a distance in the place ahead of coalcutter walking in passage, and steel cable one end that coalcutter is drawn walking mechanism is fastened and put on stanchion.After coalcutter started, chain drove sprocket and cuts at work plane, and simultaneously, coalcutter advances along the coal seam in passage under the effect of traction walking mechanism, thereby realized the cutting automatically continuously to the coal seam, greatly reduced miner's labour intensity working environment.
The coalcutter that the utility model discloses, walking traction walking mechanism and coal cutting operating mechanism provide power by same motor, and are provided with the cooling dust prevention system in the motor, so coalcutter is simple and reliable for structure, prolong motor application life, reduced the generation of fault.The traction variable transmission mechanism is owing to contain the friction plate transmission; and the engagement that can manually control friction plate with unclamp; this has not only reduced the motor frequent starting; and when service load is excessive; frictional drive is secondary because the transmission failure of skidding mutually between the friction plate; coalcutter can not continue the cutting of walking forward, so just can carry out overload protection to motor.So dependable performance, fault rate is low, has significantly reduced maintenance load.The handle of traction element operated just can drive complete machine motion, simple to operation.The coal cutting running part adopts the chain type cutting, and security reliability is good.Bottom jib can rotate in 180 ° of scopes around main shaft, and the mobile tuning of coalcutter is very convenient and safe, increases the coal mining cycling rate for the short distance work plane and has created advantage.
