[0002] The geological test sampling device is an indispensable and important tool in the field of geological exploration. It undertakes the key tasks of obtaining underground rock samples, analyzing geological structures and the distribution of mineral resources. In the process of geological exploration, it is very important to understand the composition and structure of underground rock formations and the distribution of mineral resources. This information not only helps to reveal the internal structure of the earth, but also provides a scientific basis for mineral resource development and earthquake prediction. The geological test sampling device can monitor the changes in underground rock formations in real time and quickly analyze the collected samples.

[0003] For example, the Chinese authorized patent "A Sampling Device for Geological Experimental Testing" with announcement number CN219142272U includes a top frame, a first hydraulic lifting mechanism is installed at the middle position of the lower end of the top frame, a fixed platform is installed at the lower end of the first hydraulic lifting mechanism, a driving motor is installed at the lower end of the fixed platform, a driving rod is installed at the output end of the driving motor, a drill bit is installed at the lower end of the driving rod, and four vertical poles evenly distributed along a ring are installed at the upper end of the drill bit.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model adopts a flexible drill bit replacement structure. Before installation, ensure that the arc-shaped plug plate is located in the sliding groove, align the arc-shaped mounting block on the upper end face of the drill bit with the mounting groove at the bottom of the sampling tube, and plug the two together to ensure that the arc-shaped mounting block is fully extended to the inside of the mounting groove. At this time, the arc-shaped plug plate corresponds to the arc-shaped slot in the arc-shaped mounting block. Then the user pulls the adjusting head one by one to make the adjusting head drive the arc-shaped plug plate to move to the inside of the arc-shaped slot, thereby fixing the arc-shaped mounting block and ensuring its stability in this position. Similarly, in terms of disassembly, it is only necessary to pull the adjusting head in another direction to realize the withdrawal of the arc-shaped plug plate from the arc-shaped slot, and pull the drill bit downward to complete the disassembly work between the sampling tube and the sampling tube. The installation structure is convenient and easy to operate, and effectively improves the installation firmness while ensuring flexibility.

[0017] 2. The utility model uses a high-speed rotating and liftable sampling head in the sampling structure. Through the hydraulic lifting device, the drill bit can be fitted with the ground to be sampled. At this time, the reduction motor and the motor inside the driving seat are turned on, and the output shaft of the reduction motor drives the stud to rotate. Under the friction with the screw hole in the lifting column, the inner cavity of the adjustment seat guides the lifting column to drive the sampling tube to move slowly downward. At the same time, the motor in the driving seat drives the sampling tube to rotate at high speed, and the downward pressure provided by the lifting column is cooperated to make the drill bit cut the ground. As the sampling tube continues to move downward, the soil layer continuously enters the interior of the sampling tube, thereby completing the geological sampling work. The sampling device can quickly form an extension into the soil layer, which is convenient for sampling the soil layer in different environments and brings convenience to the sampling work.
