我专山区地质复杂情况,利用平原打机井工具不能充分发挥应有的作用,我们在1958年试制了人力冲击凿井机,经过一年来各地推广使用,已打成机井261眼,问题是使用劳力较多,进度不快。为此我局农田水利科全体同志在党的领导与大力支持和承德市农具厂、石油学院、机械厂、新生机械厂等大力协助下,大鼓革命干劲,苦钻60天,于1959年9月底,创造了简易动力凿井机(见23页附图)。这部机器装有两个齿轮,其中一个是整齿轮,另一个是半周齿轮,半周齿轮是主动轮,整齿轮是从动 I mountain area complex geological conditions, the use of plains hit the well tool can not give full play to its due role, we piloted in 1958 manpower impact drilling equipment, after a year to promote the use of all over, has been labeled as 261 wells, the problem is the use of labor More, not fast progress. Therefore, all the comrades of the farmland irrigation and water conservancy branch of our bureau under the leadership and support of the party and the strong support of Chengde Farm Tools Factory, Petroleum Institute, Machinery Factory and Xinsheng Machinery Factory made the Drum Revolution revolutionary. After 60 days, at the end of September 1959 , Created a simple power drilling machine (see Figure 23 on the map). This machine is equipped with two gears, one is the whole gear, the other is a half-cycle gear, half-cycle gear is the driving wheel, the entire gear is driven
