[0002] The drilling sampling device is a kind of equipment specially used in the fields of geological exploration, mineral resource exploration, etc. Its core function is to obtain samples of underground rocks, soil or lava through drilling for subsequent geological analysis, mineral evaluation or radiochemical analysis and other research uses.

[0003] The drilling sampling device used for mining geological exploration usually includes a drill, a drill rod and a lifting mechanism. During the drilling process, the drill drives the drill rod to rotate, and the lifting mechanism drives the drill to descend so that the drill rod can drill downward. During the drilling process, the rock or soil is gradually cut and falls into the sampler inside the drill rod. When the predetermined drilling depth or sampling volume is reached, the drilling is stopped and the drill is driven to rise by the lifting mechanism, so that the drill rod and the sampler inside the drill rod are taken out, and the rock or soil in the sampler is analyzed to complete the exploration of mining geology.

[0004] The lifting mechanism for lifting the drilling rig usually uses a vertically arranged linear module to directly drive the motor. During the process of removing the drill rod after drilling, the drill rod is prone to fall off or breakage due to stress concentration, which is inconvenient and difficult to ensure the safety and stability of the drill rod when it is removed.

The two groups of fixing rods 16 are respectively located on the side close to the first ring body 151 and the second ring body 152. In the embodiment of the present application, three fixing rods 16 are evenly distributed around the axis of the fixing ring 15.

[0050] Subsequently, the fixed driving ring 26 is driven to rotate by the fixed motor 25, thereby driving each fixed rod 16 to move toward the axial direction of the fixed ring 15 so that each fixed rod 16 can achieve a tight fixation on the drill rod 1, and then cooperate with the second linear module 13 to drive the movement segmentation of its own slider to pull the drill rod 1 out of the drilling area, thereby finally realizing the removal of the drill rod 1 as a whole; each fixed rod 16 clamps the drill rod 1 and then removes the drill rod 1 through multiple vertical movements, which helps to reduce the shaking and deviation of the drill rod 1 during the removal process, thereby improving the drilling efficiency and ensuring the stability and accuracy of the drill rod 1 during the removal process. In addition, by clamping different parts of the drill rod 1 multiple times, it can better adapt to the changes in different strata and rock types, ensure the smooth progress of the drilling process, and reduce drilling accidents and losses caused by changes in geological conditions.
