Development of the lithium battery-driven impact sampling drill and complete accessories

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.
