摘　　要：根据松软煤层螺旋钻进时对钻机给进机构的需求,分析了常用的钻机给进机构的特点,提出了一种组合油缸给进机构。该给进机构具有结构尺寸小、给进行程大、起拔力强等优点,满足了螺旋钻进施工的需求。According to the requirements of drilling rig feeding mechanism in screw drilling in soft coal seam, analyzed the characteristics of common drilling rig feeding mechanism, and put forward a combined oil cylinder feeding mechanism. The feeding mechanism has the advantages of small structure size, large feeding range and strong pulling force, which meets the requirements of screw drilling construction.
