Description
Technical field
The present invention relates to mine excavation field, be specifically related to a kind of one-shot and complete coal breakage and method and the enforcement of face clearly simultaneouslyThe excavating impulsion shovel of the method.
Background technology
Current widely used Prospects for mining equipment development is flitting. Its operation principle is milling type blanking, and this has just determined thisPlant the mining method ratio of reduction larger, particularly under compressive stress state, carry out fragmentation, consumed mass energy, reduced productivity ratioWith piece material rate, meanwhile, shattering process produces a large amount of dust, has caused problem and the potential safety hazards such as digging environment is severe. To sum up instituteState, in use mainly there is following defect in conventional drum shearer at present: (1) piece material rate is low; (2) dust is many,Pollute environment; (3) material under cutting units milling is more broken, and power consumption is larger, exists ample resources waste, and cost is high.
The invention that the patent No. is 200910309903.7 provides a kind of coal-mining method and has implemented the coal excavation apparatus of the method, and this is establishedStandby coal mining head comprises plow-shape plate, and the blanking sawtooth of plow-shape front edge of board and the distance of sphenoid front end are 300-800mm, therefore it fallsMaterial is divided into two parts and step with clear face, can only be split up after avalanche coal at sphenoid plow-shape plate, base plate cleaning mechanism, top boardThe sawtooth of cleaning mechanism just can be cleared up the face of producing coal, and the sawtooth of plow-shape plate formed line cutting, and resistance is large, power consumption is large, meritHeterodyne, lose time, before and after the blanking part of equipment and clear face portion, separate and increased complete machine length, the part-structure that makes to mine is strongDegree reduces, the shock-resistant and resistance to folding poor performance of breaking, and the life-span is short, and device structure is huge, and going slick property is poor.
The patent No. is that the impact head of 200620137402.7 utility model patent and striking arm do not impact after coal breakage coal faceCleaning structure, its multiple striking arms are that multiple spot is connected with the connected mode of headstock, the fixing side of multiple impact heads and striking armFormula complexity, causes the loaded down with trivial details rapid wear of operating structure, multiple impact heads and striking arm is not combined on a fixed part, utilizesFixed part is simplified, and impact-absorbing head, the reaction force of striking arm to fuselage and headstock simultaneously makes equipment be difficult to use.
The patent No. is the patent of invention fragmentation that 201020274464.9 utility model crushing heads and the patent No. are 201010238402.7Head, does not all impact the cleaning structure to coal face after coal breakage, therefore it is smooth to clear up the coal-winning machine of sening as an envoy to after its impact grinding ribThe coal face moving ahead, cannot make coal-winning machine advance continuously, and the utility model patent shortcoming that is 200620137402.7 with the patent No. is identical.
Therefore, be badly in need of at present that brief, scientific and reasonable, the compact practical action of a kind of structure completes coal breakage and clear face simultaneouslyDigging head, raises the efficiency when taking lump coal to realize.
Summary of the invention
The object of the present invention is to provide one-shot to complete the method for coal breakage and clear face simultaneously and implement the excavating impulsion of the methodShovel.
