Or return the mixed coal stepped on and reprint onto subordinate's belt feeder.Tunnel operating mode when, flexible train be reduced to it is most short, with to it is broken reprinting unit after
Face, with driving unit（Including crushing elevating conveyor）Drilling depth and extend, general extension elongation is the drilling depth of two diggings class（200
Rice）When efficiency highest.Extend operating mode：It is motionless that steel truss train firmly grasps ground, the unmanned steering mechanism's steel wire rope of afterbody freely it is short with
Broken elevating conveyor midpoint connection, when driving unit advances, pulls the navigation steel wire rope being connected with broken elevating conveyor, touches speed and passes
Sensor, material feeding navigation tractor live axle is received to be started after this signal, rearwardly direction running, at this moment, conveyor belt tension
Increase, after conveyor belt tension is more than range of set value, constant tension winch reversion into pump work state, discharges steel wire rope, moved about
Dolly is retracted by adhesive tape, is travelled to heading, adhesive tape is discharged, flexible train is elongated.Until flexible train and driving
Unit is synchronous, and when flexible train is very fast, during more than driving unit speed, velocity sensor contact is inverted, material feeding navigation tractor
Live axle is received to slow down after this signal, until flexible train is synchronous with driving unit.Adhesive tape in cassette holder is stored up all to stretch out
When, first carrying roller car touches limit switch, material feeding navigation tractor live axle power-off parking, brake locking.Conveyor belt tension

Flexible train be reduced to it is most short, into maintenance crew.Shorten operating mode：It is fixed that steel truss train oil cylinder holds out against ground, afterbody nobody
The steel wire rope free end of steering mechanism is connected with automatic pulverizing elevating conveyor midpoint, when automatic pulverizing elevating conveyor is moved forward, steel wire
Relaxation of restricting is automatic to be shortened, and velocity sensor is perceived after this signal, controls material feeding navigation tractor drive device to heading
Traveling, until, while promotion stretch train shortening synchronous with automatic pulverizing elevating conveyor,（Flexible train itself has guide function）,
Now adhesive tape is relaxed, and conveyor belt tension is less than setting value, and constant tension winch is rotated forward（Operation status of motor）, travelling car is drawn to tail
Direction running, adhesive tape is stored in cassette holder；When flexible train is very fast, during more than automatic pulverizing elevating conveyor speed, speed is passed
Sensor contact invert, material feeding navigation tractor drive device receive after this signal slow down, until with automatic pulverizing elevating conveyor
It is synchronous.When adhesive tape storage is full in storage cassette holder, last carrying roller car touching limit switch, material feeding navigation tractor drive device is disconnected
Electricity parking locking, conveyor belt tension increases to setting value, constant tension winch stall.Now complete all to shorten operating mode, into maintenance
Automatic telescopic belt conveyer, it is necessary to be adjusted to most long operating mode, into next circulation by class.Extend operating mode：First by subordinate's belt feeder
Shorten, ground grading.Automatic telescopic belt conveyer afterbody is motionless, and steel truss train oil cylinder is packed up, unmanned steering mechanism's steel wire rope connection
Subordinate's belt machine tail part midpoint is connect, into walking operating mode, to subordinate's belt feeder direction running, the flexible train shortened is stretched, this
When conveyor belt tension be more than setting value, constant tension winch reversion, into pump work state, travelling car pulls to heading by adhesive tape,
Carrying roller car is drawn close automatically, storage cassette holder release adhesive tape, and adhesive tape is moved to most long when all discharging, the touching of first carrying roller car is spacing to open
Close, the power-off of steel truss train, locking of stopping, adhesive tape is all discharged in storage cassette holder, and conveyor belt tension is reduced to setting therewith
Value, constant tension winch stall.Its head has stopped with subordinate's belt feeder tail overlap joint, steel truss train, stretches out oil cylinder and holds out against ground
Face, wheel lift, leveling steel truss, into shortening operating mode.So far automatic telescopic belt conveyer completes once automatic shorten and automatic
Return to back and step on operating mode.Go round and begin again, until exploiting field completion.
This elongation operating mode is automatic telescopic belt conveyer by most short status elongation to most long status, and complete machine is moved to heading
