Description
Technical field
The present invention relates to a kind of coal-cutting machinery, specially a kind of hydraulic open-air coalcutter.
Background technique
Drum-type open coalcutter is a kind of large-scale strip mining transformation for integrating the functions such as exploitation, broken, shipment
Equipment has certain advantage compared with traditional coal excavation apparatus, but as its complete machine power constantly increases, is having it not
Use in standby electricity condition or the insufficient coal mine of power conditions is restricted, at the same time, centre of the drum according to circular arc cutting,
For " coal piling " phenomenon than more serious, there is " residual coal " in roller forward type opencast stope ruins.
Chinese invention patent (201410761003.7 applying date 2014.12.13 of application number) discloses a kind of opencut
With caterpillar track travelling double-ended shearer.Outdoor mining caterpillar track travelling double-ended shearer, including creeper undercarriage, centre
Drag conveyor, rotary supporting device, driver's cabin, two or so rocker arm cutting means, electrical system and hydraulic and cooling spray
System, creeper undercarriage top pass through rotary supporting device and connect intermediate drag conveyor, the side of intermediate drag conveyor
Equipped with driver's cabin, left and right rocker arm cutting means, electrical system and hydraulic and cooling spray system, two or so rocker arm cutting means
Positioned at front and back end, middle part is electrical system, hydraulic and cooling spray system, driver's cabin, and left and right rocker arm cutting means has shovel
Plate, shovel board are equipped with scraping plate transmission mechanism；Scraping plate transmission mechanism two sides are equipped with star-wheel, and scraping plate transmission mechanism and intermediate scraper plate are defeated
Send machine vertically adjacent to.
Chinese invention patent (201510667978.8 applying date 2015.10.16 of application number) discloses a kind of side-mounted
Twin-roll opencast stope ruins, including crawler type walking mechanism, mainframe, operating room, hydraulic system, electrical system, spiral rolling
Cylinder cutting mechanism, drag conveyor and leather belt reshipment machine.
Summary of the invention
After main pump starting, drum-type cutting units big arm cylinder and oil cylinder of small arm it is common drive under along linear track to
On move to mining height setting value, then start belt elevating conveyor, drag conveyor, star-wheel loading machine and cutting motor, roller
Formula cutting units cutting coal seam in a rotative pattern under the driving of cutting motor, while drum-type cutting units is in big arm cylinder and forearm oil
It is moved downward under the common driving of cylinder along linear track, the even-grained ore body to be got off by cutting passes through coalcutter front
After star-wheel loading mechanism is collected, go on the drag conveyor in the middle part of coalcutter, ore body is transported to coalcutter rear portion by conveyer
Then it is unloaded on belt elevating conveyor, ore body is loaded on haulage vehicle by belt elevating conveyor.Transferring mechanism by lifting cylinder and
Angling cylinder driving, can be adjusted with vertical direction, by a small margin in the horizontal direction to meet the needs of haulage vehicle.When roller is cut
Cut after planted agent measures setting value, cutting units again under large arm oil group and the collective effect of oil cylinder of small arm, move along a straight line to
Mining height setting value after completing a cutting action, drives opencast stope ruins movement by running motor, reaches next operating point
Afterwards, running motor stop motion, cutting units are gradually reduced, and carry out cutting to coal seam, to realize that the circulation coal cutting of coalcutter is dynamic
Make.For existing equipment and the deficiency of technology, the present invention has both with repeatable accuracy height, two-way crawl, grasp force perseverance can be achieved
The features such as workpiece is convenient, flexible, is carried in fixed and vacuum chuck sticking, disengagement, transmitting etc..
The technical solution adopted by the present invention to solve the technical problems is:
A kind of hydraulic open-air coalcutter, which is combined by operating mechanism, loader mechanism, conveying mechanism, mainly by leading
Rack, operating mechanism, star-wheel loading mechanism, scratch board conveyor, belt elevating conveyor, walking mechanism, diesel powered system, hydraulic pressure system
The composition such as system, electric-control system and centralized lubricating system；The hydraulic open-air coalcutter operating mechanism is by large arm, forearm and two
The composition such as a cutting units；The hydraulic open-air coalcutter loader mechanism includes star wheel type and crab claw type；The conveyer
Structure refers to hydraulic motor and loop chain；The cutting units is made of cutting motor, retarder, cutting drum, casing mechanism etc..
As a preferred solution of the present invention, the hydraulic open-air coalcutter loader mechanism includes star wheel type and crab
Claw.
As a preferred solution of the present invention, the hydraulic open-air coalcutter operating mechanism by large arm, forearm and
The composition such as two cutting units.
As a preferred solution of the present invention, the conveying mechanism refers to hydraulic motor and loop chain.
As a preferred solution of the present invention, the cutting units is by cutting motor, retarder, cutting drum, machine
The composition such as shell mechanism.
The invention has the advantages that the present invention can remove perforated blasting from, the coal particle size of extraction is smaller, and uniformly, saves
Primary fragmentation link；Reduction production cost is adopted to open coal mine Jian, energy-saving and environmental protection improve the rate of recovery and play positive effect.
