Itisone ofthe important facilities for the mechanization and modernization ofcoal-mining production. Hence ithas important effects onthe improvement ofexcavation efficiency. Presently the design technologies ofsheares have developed relatively perfect. paring with abroad, however, the technology ofthis area isstill behindhand. Basing onassimilating the experience ofpeople has worked inthis area, this design, schemes out High-power sheare which issuitable for medium thickness seam. Itdoes innovatory design onthe cutting unit ofshears by resorting todisposal symmetry ofMightiness Worn Roller, which improves the cutting effect and longevity. Atthe same time itreduces the wastage of truncation straight and customers ’cost. AstoMachine driven system, its transmission resorts tospur gear and ary wheel. Hence the transmission efficiency isimproved and its installation and maintenance are easier. Two ofthe departments ofcrop are driven bytwo separate 250kw- electromotors. The modulation range ofelectromotors ’capacity inthe departments ofcrop islarge, which isranging from 150kw to300kw. Through the modulation of the electromotors ’capacity, the one machine-multi-type style can becarried out. The departments ofcrop resort toglobe certificate floating structure, whose carrying capacity islarge and reducing the structure measure. The applications ofply rockerarm increase the coal ’stransit space and improve the coal ’sload effect
