Description
Technical field
The invention belongs to the digging field, be specifically related to a kind of water cutter digger.
Background technology
Existing coal-mining method has mechanical coal-mining method, hydraulic mining method, blasting coal mining method etc.Modern mechanical coal-mining method be can't use under some utmost points inclinations or unsettled coal seam conditions, hydraulic mining method or blasting coal mining method often adopted.Present hydraulic mining method is to adopt hydraulic giant fixed point jet impulse coal breakage, the hydraulic giant range has determined the coal mining distance, adopt this coal winning technology, required hydraulic pressure is large, the water yield is more, and hydraulic giant is larger with the coal dropping point distance, adopts in process as occurring rushing, the buttress inside ceiling panel is caving or alters cash in advance, block monitoring, punching is adopted in advance finish, the rate of extraction is low.
The blasting coal mining method is that employing method of drilling and blasting on rib is mined, and coal mining efficient is low, dangerous large, is more original a kind of coal-mining method.
In condition coal seam preferably, widely used is mechanical coal-mining method, and the coal excavation apparatus that mechanical coal-mining method mainly adopts is drum shearer or coal plough.Drum shearer productivity ratio is high, but lump coal rate is low, dust is large; The coal plough lump coal rate is higher, dust is little, but production efficiency is low, the coal seam bad adaptability.
Current widely used mining excavation equipment is mainly boom-type roadheader.Its operating principle is drilling formula driving, this has just determined that this driving method grinding ratio of reduction is larger, particularly grind fragmentation under compressive stress state, consume mass energy, reduced driving productivity ratio, the propelling of drill bit is completed by the walking of fuselage, in order to make the quick drilling of drill bit, the thrust of accelerating driving progress fuselage continues to increase, and because rib or crag are in larger compressive stress state, causes the damage of fuselage and drill bit larger.
Its reciprocating impact device drill hammer of reciprocating impact drilling machine, impact when making bit, but the kinetic energy of percussion mechanism is by the drill bit transmission, and is excessive because of the drill bit volume weight, the kinetic energy of reciprocating impact absorbed consumption very large, therefore consume energy excessive, practical acting is little, again because drill bit is to slide in front and back, therefore in the process of bit, forward propulsion weakens, a part of spinning movement is alleviated the effect of material, cause that in the backhaul of reciprocating impact action, bit drills pick power reduces.
Impact type tunnel boring machine is in order to destroy the compressive stress of crag rib, strengthen drivage efficiency, added vibrator at brill pick head, vibrator is the cam vibrator, but its impact amplitude to the crag rib only has 4mm, can only play the minimum destruction of crag rib bearing stress, therefore milling the formula development machine with original brill does not have large difference, and efficient is basic identical.
The problem that exists in order to solve above-mentioned technology and equipment, when the present invention proposes the compressive stress such as a kind of water cutter degree of depth cutting damage rib, crag, cut the destroyed rib of rear compressive stress, crag etc. by impact, improve the water cutter cutting of digging efficient and impact digger.
