[0038] See also Figure 6-7 , and on the basis of the first embodiment, a sampling mechanism 6 is further obtained.

[0039] The sampling mechanism 6 includes a fixed frame 61, which is fixedly connected to the left side of the top of the base 1.

[0042] In actual operation, when the device is used, the device is moved to a designated position and the rock is started to be drilled. During the drilling process, the dust suction pump is started. The dust suction pump sucks the dust generated by the drill bit 613 drilling the rock into the box 515, and the gas is discharged from the outlet pipe 517. The filter 518 in the outlet pipe 517 blocks the particulate impurities in the gas.

Then the second motor 69 is started to rotate the internal threaded tube 611, the sampling tube 612 and the drill bit 613. Then the first motor 63 is started to rotate the second screw 62. The rotation of the second screw 62 will move the screw block 64 downward, thereby moving the fixed block 68 downward, further driving the drill bit 613 to drill the rock. After drilling is completed, the second motor 69 is stopped, and the sampling tube 612 is moved upward by the operation of the first motor 63. The drilled core will be in the sampling tube 612, and then the sampling tube 612 will be taken out from the internal threaded tube 611.
