[0060] Furthermore, the liquid sampling mechanism 5 also includes a third elastic member 52, which is located in the second annular cavity 412 and is sleeved on the outer periphery of the piston rod. The upper end of the third elastic member 52 is connected to the second slip ring 44, and the lower end of the third elastic member 52 is connected to the bottom of the second annular cavity 412.

[0061] In this embodiment, the liquid collection chamber 225 is provided in plurality, and the plurality of liquid collection chambers 225 are arranged at intervals along the circumference of the sampling tube 22 . Accordingly, the collection port and the piston assembly 51 are both provided in plurality.

[0062] In order to better understand the present invention, the following Figures 1 to 13 The technical solution of the present invention is described in detail: When in use, the mobile vehicle 1 is moved to the desired location for investigation, and then the drill rod 21 and the sampling barrel 22 are assembled, and the suction pipe 33 is connected to the suction end of the suction pump. The first motor 242 drives the screw rod 241 to rotate and drive the mounting seat 23, the drill rod 21 and the sampling barrel 22 to move downward. When the mounting seat 23 moves downward, the second motor 251 drives the drill rod 21 and the sampling barrel 22 to rotate, so that the drill bit 221 drills into the ground, and the soil and gravel enter the sampling barrel. 22, the drill bit 223 and the drill bit 221 can break up the soil and gravel, start the suction pump, and generate negative pressure in the waste box 31 through the suction pipe 33. The negative pressure generated in the waste box 31 can be sucked into the waste box 31 through the air inlet pipe 32 and the channel 211. The excess soil in the drilling process is processed through the waste box 31. When the sampling tube 22 is probed to the required sampling depth, the first motor 242 drives the screw rod 241 to reverse. The second annular cavity 412 is rotated in the direction of rotation, thereby driving the mounting seat 23 to move upward and taking out the sampling tube 22. At the same time, the valve is opened, and the suction pump extracts the air in the second annular cavity 412 through the channel 211 and the connecting pipe 48, so that the second annular cavity 412 is in a negative pressure ring, thereby driving the second slip ring 44 to move downward, and the second slip ring 44 drives the first slip ring 42 downward through the connecting pipe 45, thereby pressing the liquid into the elastic clamping sleeve 43. As the liquid is injected, the elastic clamping sleeve 43 expands inwardly, thereby clamping the sample to prevent the sample from accidentally falling. Then the negative pressure component is closed, and the second slip ring 44 moves upward under the drive of the first elastic member 46 to return to the initial position to complete the sampling work. When the second slip ring 44 moves downward, it drives the piston assembly 51 to move downward, so that the space between the piston assembly 51 and the top of the liquid collection chamber 225 forms a negative pressure, thereby sucking the liquid on the periphery of the sampling tube 22 into the liquid collection chamber 225 through the collection port, thereby completing the liquid sampling.

[0063] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
