:巖(yan)(yan)石開鑿機是(shi)(shi)開采(cai)巖(yan)(yan)石的一(yi)種(zhong)機器(qi)。目前(qian),是(shi)(shi)用電(dian)(dian)鉆、風鉆打眼再用爆破的方法開采(cai)巖(yan)(yan)石,這樣不僅勞動(dong)強度大,而且(qie)效(xiao)率低。本(ben)實用新型是(shi)(shi)設計一(yi)種(zhong)新型機器(qi),其特征是(shi)(shi)通過用電(dian)(dian)加熱兩個炭電(dian)(dian)極產生電(dian)(dian)弧,在電(dian)(dian)極中間通過氮氣(qi),氮氣(qi)在高溫下電(dian)(dian)離火(huo)焰達(da)5000℃,使巖(yan)(yan)石受熱破裂,層層剝(bo)皮,以(yi)達(da)到開采(cai)之目的。。
