Description

Technical Field

[0001] The utility model relates to the technical field of paleomagnetism, in particular to a core sampler. Background Art

[0002] Paleomagnetism, also known as natural remanent magnetism, refers to the geomagnetic field in human prehistory and history. Rocks in various geological eras often have a certain magnetism, indicating the direction of the magnetic poles during their formation. They are magnetized by the geomagnetic field during the cooling or sedimentation process, and record the direction and intensity of the geomagnetic field during the rock formation period. Therefore, in the study of geomagnetic activity, it is necessary to use corresponding samplers and conduct targeted tests to explore more secrets about geomagnetism.

[0003] According to a core sampler disclosed in patent search announcement number CN206655671U, its beneficial effects are: after sampling, the core tube can be opened and split into multiple hollow tubes, and the core can be directly taken out from the hollow tubes without the need to use mud to flush the inside of the core sampler, so it will not cause contamination to the core. At the same time, coring is simple and convenient.

[0004] When drilling cores and taking samples, the rocks are not restrained or fixed during the drilling process, which causes the rocks to slide irregularly, resulting in failure of core sampling and possible damage to the drill rod used for sampling. Utility Model Content
