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 section and a fixing section. The impulse cutting 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 the digging that a kind of one-shot accomplishes the method for coal breakage and clear face simultaneously and implement this method and dash shovel.
Background technology
Current widely used mine excavation equipment is flitting.Its operating principle is a milling formula blanking; This has just determined that this kind digging mode ratio of reduction is bigger, particularly under compressive stress state, carries out fragmentation, has 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 potential safety hazards such as the digging environment is abominable.In sum, in use mainly there is following defective in drum shearer commonly used 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 bigger, exists the ample resources waste, and cost is high.
The patent No. is the coal excavation apparatus that 200910309903.7 invention provides a kind of coal-mining method and implemented this method; 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; So its blanking is divided into two steps with clear face, can only sphenoid rise split the avalanche coal after, the sawtooth of plow-shape plate, base plate cleaning mechanism, 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, and resistance is big, effect is poor, lose time.
Therefore, be badly in need of the digging head that an a kind of action rational in infrastructure, compact is accomplished coal breakage and clear face simultaneously at present, raise the efficiency when taking lump coal with realization.
Summary of the invention
