Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as Figure 1~5 , a simple ultra-large-diameter coring drill core sample extraction device, including a core tube 1, the core tube 1 of this embodiment is a hollow cylindrical structure with upper and lower ends open, and the upper end is threadedly connected to the drill pipe 2 through a connector The lower end is equipped with a cutting tooth block 3, and the rock core is cut by the tooth block 3 to realize sampling.
[0025] In this embodiment, the side wall of the core tube 1 is provided with multiple sets of limiting structures, and the multiple sets of limiting structures are arranged at intervals along the circumference of the core tube 1. In this embodiment, there are two groups, and the two sets of limiting structures are symmetrically arranged. Such as Figure 1~4 As shown, the side wall of the core tube 1 in th...
