CORE SAMPLING DEVICE
PROBLEM TO BE SOLVED: To provide a core sampling device which can cool a bit, and which can achieve reduction in costs required for a boring device and boring work and miniaturization of the boring device.SOLUTION: A core sampling device includes: an outer pipe which has a bit at a lower end; an inner pipe which is arranged coaxially with the axis of the outer pipe, within the outer pipe; a fluid container which is arranged in the inner pipe, which has a storage space for accommodating a fluid, and which can be contracted in the axial direction of the inner pipe; and a fluid passage that is a fluid passage communicating with the bit. The storage space of the fluid container communicates with the fluid passage.
【課題】ビットを冷却することができるコア採取装置であって、ボーリング装置やボーリング作業にかかるコストを低減し、ボーリング装置の小型化を図ることができるコア採取装置を提供する。【解決手段】コア採取装置は、下端にビットを有する外管と、外管内において外管の軸と同軸に配される内管と、内管内に配され、流体が収容される収容空間を有し、内管の軸方向に収縮可能な流体容器と、ビットに通ずる流体の通路である流体通路と、を備え、流体容器の収容空間が流体通路に通じている。【選択図】 図１
