凿岩机 利用钢钎的冲击和旋转作用在岩石上钻凿孔眼的石料开采机械。主要用于开采石料或拆除废弃建筑物。凿岩机分风动式、电动式、内燃式和液压式四类。风动式以压缩空气驱使活塞在气缸中向前冲击，使钢钎凿击岩石，应用最广。电动式由电动机通过曲柄连杆机构带动锤头冲击钢钎，凿击岩石。内燃式利用内燃机原理，通过柴油的燃爆力驱使活塞冲击钢钎，凿击岩石。适用于无电源、无气源的施工场地。液压式依靠液压通过惰性气体和冲击体冲击钢钎，凿击岩石。这些凿岩机的冲击机构在回程时，由转钎机构强迫钢钎转动角度，使钎头改变位置继续凿击岩石。如此不断地冲击和旋转，并利用排粉机构排出石屑，即可凿成炮孔。 参考书目 陈玉凡：《矿山机械》,冶金工业出版社，北京,1981。
