HQD70型电动潜孔钻机
HQD70型电动潜孔钻机是一种新型高效适用性较广的凿岩设备，广泛地适用于中小型矿山及交通、国防、水利、石方等工程，尤其适用于其他钻车无法正常作业的凹凸的崎岖地势。该机结构简单、操作方便、价格低廉、节约能源，同时还具有钻凿垂直和水平爆破孔的功能，特别是该机重心低可拆性好，搬迁运输极为方便。
主要特点
● 结构简单、操作方便、价格低廉；
● 重心低可拆性好，搬迁运输方便，特别适合在凹凸的崎岖地势或原始地貌；
● 冲击器耗气量低，配套所需空压机排气量小，节能经济；
● 回转减速器扭矩大，在强振动、高负荷的工作条件下，可靠性好。
● 电器系统具有过载保护和缺相保护功能，使钻机运行稳定可靠。
● 推进系统配置了减压阀，可根据不同的岩石条件下调整推进力，以获得最佳的凿岩效果。
