Abstract
The invention relates to the field of mine excavation, and specifically relates to a method used for simultaneously achieving coal breaking and surface cleaning with one time of impulsion, and an excavating impulsion shovel used for realizing the method. The excavating impulsion shovel comprises an impulse-cutting coal breaking and surface cleaning section and a fixing section. The impulse-cutting coal breaking and surface cleaning section comprises shovel teeth which are arranged on fixing components. The shovel teeth are positioned at the front part of the excavating impulsion shovel. The shovel teeth and the height of the coal seam requiring excavating form an I shape, a J shape and/or a ] shape. Coal breaking and surface cleaning are simultaneously achieved with one time of impulsion. With the arrangement of the cutting edges of the shovel teeth, a plane relative to a coal mining machine walking direction can be cleared. The pressure on the top of the excavating impulsion shovel is concentrated, such that a large impact force can be generated in a moment, and the coal seam can be broken under compressive stress. With the shapes and the arrangement of the shovel teeth fixed on the fixing components, coal breaking and surface cleaning can be simultaneously achieved with one movement. Therefore, with the excavating impulsion shovel, coal mining efficiency can be improved in respects of structure configuration, time utilization and impact force utilization. Energy and time can be utilized and saved to a maximal extent, and an equipment structure is optimized and simplified.
Description
Technical field
The present invention relates to the mine excavation field, be specifically related to a kind of one-shot and complete simultaneously coal breakage and the method for clear face and the excavating impulsion shovel of implementing the method.
Background technology
Current widely used Prospects for mining equipment development is flitting.Its operating principle is the milling type blanking, this has just determined that this kind mining method ratio of reduction is larger, particularly carry out fragmentation under compressive stress state, consumed mass energy, productivity ratio and piece material rate have been reduced, simultaneously, shattering process produces a large amount of dust, has caused problem and the potential safety hazards such as the digging environment is abominable.In sum, in use mainly there is following defective in the drum shearer of commonly using at present: (1) piece material rate is low; (2) dust is many, has polluted environment; (3) material under the cutting units milling is more broken, and power consumption is larger, exists the ample resources waste, and cost is high.
the patent No. provides the coal excavation apparatus of a kind of coal-mining method and enforcement the method for 200910309903.7 invention, the coal mining head of this equipment comprises the plow-shape plate, the blanking sawtooth of plow-shape front edge of board and the distance of sphenoid front end are 300-800mm, therefore its blanking is divided into two parts and step with clear face, can only be after sphenoid be split up the avalanche coal, the plow-shape plate, the base plate cleaning mechanism, the sawtooth of top board cleaning mechanism just can be cleared up the face of producing coal, and the sawtooth of plow-shape plate has formed the line cutting, resistance is large, power consumption is large, effect is poor, lose time, separate before and after the blanking of equipment part and clear face portion and increased complete machine length, make coal mining part-structure strength decreased, shock-resistant and the anti-folding poor performance of breaking off with the fingers and thumb, life-span is short, device structure is huge, 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 the cleaning structure to coal face, its a plurality of striking arms are that multiple spot is connected with the connected mode of headstock, the fixed form of a plurality of impact heads and striking arm is complicated, cause the loaded down with trivial details rapid wear of operating structure, a plurality of impact heads and striking arm are not combined on a fixed part, utilize fixed part to simplify, simultaneously impact-absorbing head, the striking arm reaction force to fuselage and headstock, make equipment be difficult to use.
The patent No. is that 201020274464.9 utility model crushing heads and the patent No. are 201010238402.7 patent of invention crushing head, all do not impact after coal breakage the cleaning structure to coal face, therefore can not clear up the coal face that the coal-winning machine of sening as an envoy to moves ahead smoothly after its impact grinding rib, coal-winning machine is advanced continuously, is that 200620137402.7 utility model patent shortcoming is identical with the patent No..

Front end at teeth is provided with dismountable impact head, and impact head is the front end that a kind of boots head is embedded in teeth.Impact head is made by carbide alloy, and Cemented Carbide Hardness is high, and is wear-resisting, long service life, and the shovel body that liquidates has played effective protection, has greatly improved the life-span of excavating impulsion shovel.
Described impact head can also be made by hard materials such as tool steel, alloy steels.
Described impact head also can be integral structure with teeth itself.
The other the same as in Example 1.
