Technical field:
The present invention relates to a kind of coal mining rounding machine cutter, block production is adopted in especially a kind of coal mining machine bit, realization, and improves life
Produce efficiency.
Background technique:
Coal is one of main energy in China, is played an important role to the national economic development, and demand is huge, China's coal-mine
Exploitation career development is swift and violent, to also bring the great development for equipment of mining, wherein coalcutter is exactly a key equipment, is adopted at present
Coal press proof formula is various, is typically driven by the mechanical drive cutter, carries out drilling to coal seam, so that coal cinder removing is fallen off, realizes
Seam mining, so cutter plays a crucial role production efficiency, the existing big portion of cutter is all directly to carry out to coal seam
Hardness cutting, separation need power big, and drill bit is easy to wear, and coal dust, dust are more, still solves up for technological transformation.
Summary of the invention:
To solve the above-mentioned problems, the present invention provides a kind of coal mining machine bit.
The technical solution adopted by the present invention is that: a kind of coal mining machine bit, including transmission case and drill bit, it is characterised in that bore
Head is connected to transmission case front, and transmission case is connected with power transferring arm by transmission, and the transmission case back side is equipped with coaxial with transmission shaft
Transmission case axle housing, power transferring arm be equipped with the transmission arm axle housing coaxial with transmission shaft, transmission arm axle housing outer end passes through bearing
It is connected to inside transmission case axle housing, transmission shaft is connected in transmission arm axle housing by bearing；Transmission arm is equipped with single-revolution motor,
The output shaft of turning motor is connected with single-revolution driving gear, is equipped with a coaxial revolution driven tooth outside transmission case axle housing
Wheel, revolution driven gear are engaged with revolution driving gear；A hydraulic fluid tank is connected on transmission case, hydraulic fluid tank front is arranged equipped with array
The nozzle of cloth, the spray hydraulic fluid tank back side are connected with hydraulic tube.
Further, the drill bit is 1 to 3.
Further, the injector configuration width is greater than or equal to drill bit width.
Further, the injector spacing is 3 to 10 centimetres.
When the present invention is run, the highly pressurised liquid for first passing through nozzle ejection carries out parallel wire type cutting to coal seam, then uses again
Drill bit is removed, and coal seam is blocking to fall off, and separation needs power small, and bit wear is slow, and coal dust, dust are few, while the liquid sprayed
Body can be with dust elimination, and reciprocal walking need to only drive transmission case revolution with turning motor, and hydraulic fluid tank is made to be located at transmission case always
The front of direction of travel, efficiency is high, and structure is simple, wide market.
