我院四队的革命职工,在毛主席的无产阶级革命路线指引下,抓革命、促生产,为解决冬季冻土地区勘测工作中因打桩困难而影响测量进度的问题,于75年5月开始研制冻土打桩开孔钻机,样机现已试制成功,经实践使用效果良好(见图)。该机由汽油机、离合器、减速器、主轴等四部分组成。汽油机为风冷单缸二冲程1.6马力,耗油量300~450克/小时;减速器为两级斜齿轮变速,由4000转/分变为2000转/分;离
The revolutionary staff of the fourth team of our institute grasped the revolution and promoted production under the guidance of Chairman Mao’s proletarian revolutionary route. It began in May of the year 75 to solve the problem of the measurement progress caused by difficult piling in survey work in the frozen ground in winter. Developed a perforated soil drilling and drilling rig, and the prototype has been successfully trial-produced and has been used in practice with good results (see figure). The machine consists of four parts: gasoline engine, clutch, reducer, and spindle. Gasoline engine for the air-cooled single-cylinder two-stroke 1.6 hp, fuel consumption of 300 ~ 450 g / h; reducer for two-stage helical gears, from 4000 rpm to 2000 rev / min; from
