Description

Technical Field

[0001] This utility model relates to the field of core tube technology, specifically a core tube suitable for deep well drilling. Background Technology

[0002] In mineral resource exploration, such as searching for metallic minerals (copper, iron, gold, etc.) and non-metallic minerals (such as phosphate rock, gypsum, etc.), core samples obtained from core tubes can help geologists determine important information such as the location, thickness, and grade of ore layers. For example, in some metallic mineral exploration projects in western my country, core samples obtained from core tubes have played a decisive role in determining the boundaries of ore bodies and the quality of ore.

[0003] Currently, when using core tubes, soil samples taken from inside the tube are difficult to extract due to the accumulation and compression of the samples, making sampling inconvenient. Therefore, improvements are needed. Utility Model Content

A first spring 10 is installed inside the inner tube 3. One end of the first spring 10 is fixedly connected to the inner tube 3, and the other end of the first spring 10 is fixedly connected to the guide block 8. By designing the first spring 10, the force of the first spring 10 can be applied to the guide block 8. A rotating seat 11 is rotatably connected to the inside of the outer tube 1 through a bearing. The rotating seat 11 is rotatably connected to the inner tube 3. Two symmetrically distributed rotating rods 12 are fixedly connected to the bottom plate of the rotating seat 11. A connecting mechanism 9 is installed on the rotating seat 11.

[0023] Please see Figure 1 , Figure 2 , Figure 4The connecting mechanism 9 includes a ball bearing 91. The ball bearing 91 is movably fitted inside the rotating seat 11 and is movably connected to the inner tube 3. A groove 92 is formed inside the inner tube 3, and the ball bearing 91 is movably fitted inside the groove 92. The groove 92 is designed so that the ball bearing 91 can roll within it. A slider 93 is movably fitted to the outside of the ball bearing 91. A spring block 94 is fixedly connected to the end of the slider 93 away from the ball bearing 91. The spring block 94 is cylindrical and made of high-elasticity rubber. The spring block 94 is designed so that the ball bearing 91 can roll within it.

The rotating rod 12 drives the rotating seat 11 to rotate, and the rotating seat 11 drives the ball 91 to rotate. The ball 91 will roll along the arc surface of the groove 92 and be squeezed into the rotating seat 11. The ball 91 will drive the slider 93 to move. The slider 93 squeezes the spring block 94. At the same time, the slider 93 drives the guide rod 95 to move and squeezes the second spring 96, which can separate the ball 91 from the groove 92. Then the restriction on the inner tube 3 can be released, and the inner tube 3 can slide along the inside of the outer tube 1. At the same time, the inner tube 3 drives the connecting block 4 to slide along the connecting groove 5, so that the inner tube 3 can be removed, which can facilitate the cleaning and maintenance of the internal structure of the core tube.
