| 中文摘要:冲击钻进取样是支撑生态地质调查中松散地层优质高效、原状无污染取样的有效手段，但目前常见的便携式冲击取样钻机采用汽油机驱动，不能较好地适应安全生产与绿色勘查的发展要求。鉴于此，本文研制了一种以锂电池作为动力源的便携式电动冲击取样钻机及配套工具，详细介绍了钻机的电动冲击器、控制器、锂电池动力源及配套的取样器、锂电池液压起拔器的设计选型过程，并开展了钻机取样试验。实践证明该钻机及配套工具轻便可靠，可以实现5 m以浅松散地层的安全、高效、零碳排取样，是践行绿色勘查理念、推动浅层钻探装备电动化升级的有益尝试。 |

| Abstract:Impact sampling is an effective means to get high-quality， efficient， undisturbed and pollution-free sample from unconsolidated formation in eco-geological survey. However， the common portable impact sampling drill is driven by gasoline engine， which cannot somehow meet the development requirements of safe production and green exploration. Therefore， a portable electric impact sampling drill driven by lithium battery and its complete accessories were developed. The design and selection process of the electric hammer， the controller， the lithium battery power source of the drill is introduced in detail together with the matching sampler and the hydraulic puller driven by the same lithium battery. The sampling test of the drill has been carried out. Field results proved that the portable electric impact sampling rig and its complete accessories are portable and reliable， and can get high quality samples from unconsolidated formation within 5m safely and efficiently without carbon emissions， demonstrating a beneficial attempt to implement green exploration and promote the electric upgrading of shallow drilling equipment. |
