目前地质岩芯钻机使用的给进机构型式多样，但主要型式有四种：一是手把式的给进机构（有的已改成手轮式的）；二是制动器自动给进调节器，又称钢绳减压给进机构；三是油缸油压给进式；四是全液压钻机中采用的液压马达直接驱动的封闭链式的给进机构。一、手把式的给进机构。由于各人的体力与精力关系以及操作熟练程度的不同，压力控制是无法均匀的，也就无法满足金刚石钻进工艺要求，不可能做到均匀连续的给进，因此不适应金刚石钻进。
At present, there are many types of feeding mechanism for geological core drilling rigs, but there are four main types: one is the handlebar type feeding mechanism (some of which have been changed into a handwheel type); the other is the brake is automatically fed into the regulator, Also known as rope decompression feed institutions; third hydraulic cylinder into; fourth hydraulic hydraulic rig used in the direct drive of the closed chain into the body. First, the hand-type into the body. Due to the different physical and mental strength and proficiency of operation, the pressure control is not uniform, which can not meet the diamond drilling technology requirements, it is impossible to achieve uniform and continuous feed, so do not meet the diamond drilling.
