Description
Technical field
The present invention relates to a kind of digging equipment field, especially a kind of coal petrography cutting operating mechanism.
Background technology
In coal industry programmatic document《About several opinions for promoting coal industry to develop in a healthy way》In, in national coal
In industrial science technology conference and in the coal industry the policy of construction adjustment of National Development and Reform Committee's appearance, it is large-scale to be directed to development
The contents such as coal underground performing comprehensive coal mining equipment.The speedy drivage of coal mine roadway is the key technology that coal mine ensures mine stable high yield
Measure.Efficient mechanicalization driving is to ensure that mine realizes the hair of one of necessary condition of high-yield and high-efficiency and tunnelling technology
Open up direction.Most important road heading machinery is boom-type roadheader in China's coal road high efficient driving mode.Boom-type roadheader is collection
The functions such as cutting, shipment, walking, operation are mainly used for the Rock in Well, coal or half coal petrography of cutting arbitrary shape section in one
Tunnel.Now domestic development machine design can meet the needs of domestic substantially, but with a certain distance from also having from international advanced technology.And
Still based on drilling and blasting method, driving of the heavy boom-type roadheader for large rock-gateway is in domestic construction of rock gangway at present in China
Experimental stage.Big gun digs technology, and that there are safeties is low, tunnel it is secondary destroy, dust is big, driving speed is slow, the length of service is short, repair
The problems such as costly.Boom-type roadheader therefore, it is possible to be competent at cutting hard rock is badly in need of technological innovation.Cutterhead is development machine
Execution unit, performance is good and bad, directly determines the economic benefit of coal mining.In order to accelerate the production domesticization of high efficient driving equipment
Process improves coal petrography cutting efficiency, and it is imperative to carry out structure design to cutterhead.
Overhang portion section boring machine is mainly used for coal road and alternate heading driving, the arm-type partial cut-away driving of front overhang
The operating mechanism of machine uses the cutterhead of more picks configuration, from Cutting Performance, it is difficult to meet cutting wellf>8 or more it is complete
Rock gangway, not only tool wear is extremely serious, and the big energy consumption of Dust Capacity obviously increases, and therefore, develops the cantilever suitable for total rock tunnel
Formula partial-size tunneling machine operating mechanism, very urgently.
Invention content
Patent of the present invention is designed to provide a kind of coal petrography cutting operating mechanism, realizes mechanical cutting and high-pressure water jet
Compound coal petrography cutting is distributed multiple cutters tooth on cutting cutterhead, and cutting cutterhead can rotate freely, and reduces cutter tooth abrasion, improves
Coal petrography cutting efficiency.

A kind of coal petrography cutting operating mechanism, the coal petrography crushing mechanism include cutter head shaft, cutterhead mounting disc, cutting knife
Disk, cutterhead mounting disc fixation end cap, cutterhead mounting disc positioning jump ring, cutterhead positioning jump ring, cutterhead are fixed end cap, are cut
Cut a mounting disc attachment screw, cutterhead shaft end ring, cutterhead mounting disc and cutting cutterhead sealing shroud, cutterhead mounting disc with
Cutting cutterhead sealing ring, cutterhead mounting disc and cutter head shaft sealing shroud, cutterhead mounting disc and cutter head shaft sealing ring.
Further, there are several cavernous structures one on the cutter head shaft, the axially bored line is parallel with cutter head shaft axis,
There are several cavernous structures two simultaneously on cutter head shaft, the axially bored line is vertical with cutter head shaft axis, cavernous structure and poroid knot
Structure is used for leading to high pressure water.
Further, there are several tooth-shape structures, inside to install several nozzles, have circle in nozzle on the cutting cutterhead
Post holes, taper hole and spray holes ensure that the high pressure water ejected from nozzle has atomizing effect.
Further, the nozzle is connected with water outlet, and water outlet is located among two tooth-shape structures, nozzle fixed plug
For installing fixed nozzle, nozzle fixed plug is hollow-core construction, and outer surface has helicitic texture.
Advantageous effect of the present invention：
Coal petrography cutting operating mechanism of the present invention has：1, coal petrography cutting operating mechanism of the present invention realizes
Mechanical cutting and water jet assisted machining composite breaking, the more existing coal petrography cutting operating mechanism of cutting efficiency improve 60%.2, this hair
The bright coal petrography cutting operating mechanism, connection is reliable, and convenient for safeguarding, cutting cutterhead can freely be revolved around itself axis of rotation
Turn, cutting cutter life improves 40% or more.3, coal petrography cutting operating mechanism of the present invention is auxiliary due to the use of water jet
Cutting is helped, the dust in the course of work is greatly reduced, improves working environment.4, coal petrography cutting working machine of the present invention
Structure, mechanical structure are simple, reliable.
