Description
Technical field：
The present invention relates to coal mine fully-mechanized mining drag conveyor field, it is a kind of adjustable coarse coal with precrushing function
Breaker and drag conveyor.
Background technology：
With the continuous exploitation of medium-thickness seam, the wall caving of fully-mechanized mining working rib and roof fall phenomenon are more and more frequent, sometimes
The very big coal cinder of granularity can be produced, these coarse coals easily produce swipe at the head unloading of drag conveyor, coal is miscarried
Raw blocking and the effect being detained, also can increase running resistance simultaneously, and ultimately result in equipment downtime it is therefore desirable to coarse coal exists
It is broken for moderate granularity, the normal operation of guarantee coal stream in time at drag conveyor unloading.Published at present such
Breaker, generally fixed or impact type, adjustable scope is less, especially the crushing operation of ultra large coal cash is fitted
Answering property is poor, or even also can produce new inhibition it is still necessary to carry out to coarse coal because of self structure to ultra large coal cash
Hand breaking, high labor intensive, security is poor, is therefore badly in need of one kind safely and effectively coarse coal breaker.

Include base 1, the first bearing pin 2, hoist cylinder 3, right angle seat 4, the second bearing pin 5, the 3rd bearing pin 6, telescopic oil cylinder 7, the 4th bearing pin 8,
Telescopic stand 9, drive division 10, breaker roll 11, guard shield 12, base 1 is arranged on support baseboard outside the mined out side of lead-over groove spillplate 16
On, hoist cylinder 3 one end is hinged with base 1 by the first bearing pin 2, and the other end is hinged with right angle seat 4 by the second bearing pin 5, stretches
Contracting oil cylinder 7 one end is hinged with right angle seat 4 by the 3rd bearing pin 6, and the other end is hinged with telescopic stand 9 by the 4th bearing pin 8, lifting oil
Cylinder 3 is vertical with telescopic oil cylinder 7, and drive division 10 is coupled with telescopic stand 9 and breaker roll 11 respectively, and drives breaker roll 11 to rotate, shield
Cover 12 is coupled with drive division 10.
Further：In the presence of hoist cylinder 3 and telescopic oil cylinder 7, achievable high and low position lifts described breaker roll 11
The linear motion stretching with front and back position, and can lock optional position at the volley；When breaker roll needs to be preferably minimized position
When putting, the bolt on the gusset piece 17 fixing with spillplate 16 can be unclamped, pull down moveable splash board 18, now coal after crushing
Block granularity disclosure satisfy that normal conveying requires, and the flexible broken scope being formed of breaker roll can cover the width of lead-over groove.
Further：Described base 1 and telescopic stand 9 groove all with symmetrical configuration, the relevant position of right angle seat 4 carries knot
The symmetrical guide pad of structure, the groove of base 1 and telescopic stand 9 is socketed with the guide pad of right angle seat 4 respectively, and right angle seat 4 can be along base 1
Straight line lifts, and telescopic stand 9 can be along right angle seat 4 linear telescopic, and base 1, telescopic stand 9 no relatively rotate respectively and right angle seat 4 between.
Further：Carry crushing teeth uniform side by side on the excircle of described breaker roll 11, can rotate along coal stream direction,
Simultaneous with dismountable guard shield 12, all do not send out with hydraulic support top beam 13, coal mining machine roller 14 and conveyer pin rail 15 position
Raw interference, does not affect the normal operation of hydraulic support and coal-winning machine.
Further：The adjustable coarse coal that described drag conveyor is provided with content as described in any of the above-described crushes dress
Put.
The present invention is arranged on the mined out side of transition groove for scraper conveyor spillplate 16, and spillplate 16 carries gusset piece 17, can
Fixed with bolt with moveable splash board 18, conveyer pin rail 15 is located at the rib side of lead-over groove spillplate 16, as coal-winning machine walking
Engagement track, coal mining machine roller 14 carries out circumgyration incision rib, and hydraulic support is coupled with conveyer, and hydraulic support top beam 13 is used for
Support the rib at the top of conveyer.
After said structure, the broken granularity according to needed for coarse coal of attendant, can extremely close remote control breaker roll
Right position is put and is rotated, and carries out crushing operation to coarse coal, after crushing operation terminates or during without crushing operation, can be by breaker roll
Shut down and be retracted to initial correct position.
Advantages of the present invention：1) adaptability is good, larger to the crushed scope of coarse coal, and the upper height limit of breaker roll is liquid
Pressure set cap lower edge, height lower limit is edge on scraper chain, and the flexible broken scope being formed of breaker roll can cover lead-over groove
Width；2) security is good, and breaker roll is arranged on outside the mined out side of spillplate of lead-over groove, its rotation, lifting and flexible by
Electrohydraulic system remote control completes, and need not manually carry out high intensity and dangerous crushing operation, and spillplate and guard shield all can hinder
The cinder splashing after gear is broken；3) compact conformation, Maintenance and Repair are convenient, take conveyer transition slot space less, with pin rail position
Put and do not interfere, do not affect the normal operation of coal-winning machine and hydraulic support, in the case of without crushing operation, can will crush
Roller is retracted to initial correct position, does not affect the normal operation of coal stream.
