[0002] In areas where rock fracture structures are developed in mines, the degree of rock fragmentation is high, and the cores are usually muddy, sandy, and clastic. At present, mining geological drilling requires that all cores be taken out. Since the current core box is usually a structure with a closed bottom and surroundings and an open top, such as a core box for counting core sizes for geological exploration disclosed in Chinese utility model patent 202320577823.5. Core boxes of this structure make it difficult for operators to sample muddy, sandy, and clastic cores, and they often need to use tools to dig them out of the core box. In this way, the samples remaining on the tools will contaminate each other, causing inaccurate test data, and the core sampling will be inefficient with the help of tools. Furthermore, geologists often need to use tools such as tape measures to measure during the cataloging and sampling process, which affects work efficiency. If you forget to bring a ruler, it will also directly affect the accuracy of cataloging and sampling. In addition, existing core boxes are often easy to pinch your palms when transporting, posing a safety hazard. Utility Model Content
