Technical field
Coal Mining Technology field is the utility model is related to, specially a kind of Coal Exploitation mining drill bit.
Background technology
Colliery is the mankind in the region of the mining area exploitation coal resources rich in coal, is generally divided into underground mine and outdoor coal
Ore deposit.When coal seam is remote from earth's surface, it is typically chosen to underground and digs tunnel digging coal, this is underground mine.When coal seam is away from earth's surface
Distance it is close when, be typically chosen directly peel off surface soil layer excavate coal, this is open coal mine.China overwhelming majority colliery belongs to
In underground mine.Colliery scope includes above and below ground and the very big region of related facility.Colliery is the mankind in digging rich in having
The proportional space excavated during the geological stratification of coal, generally include tunnel, well cave and face etc..Coal is most important solid
Fuel, it is one kind of kaustobilite.It is the plant in great numbers grown by certain geological epoch, in suitable geological environment
In, thick-layer is gradually piled into, and be buried in water-bed or silt, formed by very long geochronic geochronic natural incoalation
's.It is most with producing coal in the stratum in the Carboniferous Period, the Permian Period, Jurassic Period and the Tertiary Period in the world in Various Geolcgical Ages, it is important
Coal-forming age.The phosphorus content of coal is generally 46~97%, brown to black, has dim to metallic luster.According to coalification
The difference of degree, coal can be divided into peat, lignite, bituminous coal and the class of anthracite four.
In process of coal mining, traditional drill bit structure in use, can produce substantial amounts of dust, and stone
Splashing can be produced in boring procedure, easily accidentally injures personnel, there is certain limitation.
Utility model content
The purpose of this utility model is to provide a kind of Coal Exploitation mining drill bit, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of Coal Exploitation mining drill bit, including this

Road both sides are provided with the groove that produces coal, and described body side surface is further opened with cutting notch.
Preferably, the neck offers material spilling hole in both sides up and down, and material spilling hole is provided with plunger.
Preferably, polishing nail circular array on body is distributed, and the polishing nail is provided with six groups.
Preferably, it is equipped with external screw thread on the outside of the drilling rod and connector.
Preferably, opening is set on the left of the neck, and the neck left end is provided with rubber blanket.
Preferably, circular arc chamfering is offered on the right side of the drilling rod and on the right side of connector.
Compared with prior art, the beneficial effects of the utility model are：A kind of Coal Exploitation mining drill bit of the utility model, knot
Structure is novel, and easy to operate, coal cinder is ground to duff by nail of polishing, and by producing coal, groove can be ejected easily, by boring
Bar part is threaded with neck, in boring procedure, can effectively stop the stone or dust from flying of splashing, avoids pair
Staff causes to damage, and has certain protective effect, while mini fan can be quickly by after caused adsorbing powder dust
It is unified to be discharged at one, avoid dust from flying upward everywhere, there is very high practicality, greatly improve a kind of Coal Exploitation mining drill
The use feature of head, ensures its using effect and utilization benefit, is adapted to be widely popularized.
