ZFI型气腿式凿岩机是上海风动工具厂、铜川矿务局和上海煤炭机械研究所组成的以工人为主体的三结合小组设计的新产品。该机由上海风动工具厂试制。曾在北京大安山煤矿和安徽铜陵铜矿进行了工业试验。1975年进行了小批生产,在大屯矿、张家洼,开滦煤矿使用。本机主要用于金属矿山巷道掘进、采矿,进行凿孔作业;也是铁路、水利建设和国防建设等各种石方工程中的重要工具。与ZFIU型注油器和ZFIJ型气腿配套,可对中硬和坚硬岩石进行显式凿岩,钻凿水平和倾斜炮孔。
ZFI type air leg rock drill is a new product designed by the combination of workers as the main body which is composed of Shanghai Fengdong Power Tools Factory, Tongchuan Mining Bureau and Shanghai Coal Machinery Research Institute. The aircraft by the Shanghai pneumatic tools factory trial. In Beijing Da’an Coal Mine and Tongling Copper Mine in Anhui conducted an industrial test. Small batch production took place in 1975 and was used at Datun Mine, Zhangjiawa and Kailuan Coal Mine. This machine is mainly used for metal mine roadway excavation, mining, drilling operations; also railways, water conservancy construction and national defense construction and other stone tools in an important tool. Combined with the ZFIU type oil injector and ZFIJ type air leg, it is possible to drill moderately hard and hard rock, drill horizontally and tilt the hole.
