[0062] A method for using a geological survey sampling device comprises the following steps:

[0063] S1: Installation of sampling mechanism 5:

[0064] S1, 1: Assemble the sampling part 7 with a drill barrel B61:

[0065] Insert the triangular pyramid Y66 into the triangular slide groove A718 to provide a guiding effect, so that the slide rod Y65 slides into the triangular slide groove A718, and rotate the drill barrel B61 so that the internal thread ring groove B67 and the external thread ring A716 are threadedly connected to form a fixed connection;

[0066] S1, 2: According to the depth of geological exploration sampling, adjust the total length of the drill rod part 6 and the sampling part 7, assemble and fix multiple drill barrels B61 with reference to step S1, 1, and install the drill barrel B61 at the top on the rotating mechanism 3. At this time, the sampling part 7 is in a pre-drilled state;

[0067] S2: Pre-drilling for geological survey sampling:

[0068] The output shaft of the motor A32 is controlled to rotate by an external control mechanism to drive the rotating rod 37, the rotating column X35 and the sleeve ring 34 to rotate, and the eccentric end of the plug rod 343 rotates relative to the rotating cavity. The lifting mechanism 2 is controlled to descend by the external control mechanism, so that the sampling mechanism 5 can drill holes, and the geological materials of the drilling group are introduced from the gaps between the several screw cutters A72 to the gaps between the several screw cutters B62 and then led out of the ground until the sampling part 7 is drilled to an appropriate depth;

[0069] S3: Sampling for geological survey:

[0070] S3, 1: Adjustment of the adjustment mechanism 4:

[0071] The output shaft of the motor B49 is controlled to rotate by an external control mechanism, and the rotation of the worm 48 drives the worm ring 45 to rotate, so that the movable ring block 47 moves on the inclined guide groove 46, so that the slide bar 43 slides to the eccentric end of the centripetal groove 42. The output shaft of the motor A32 is controlled to rotate by an external control mechanism to drive the rotating rod 37, the rotating column X35 and the collar 34 to rotate. When the eccentric end of the plug rod 343 rotates to the position of the centripetal groove 42 relative to the inner edge surface of the lower ring 41, the plug rod 343 is inserted into the centripetal groove 42. At this time, the output shaft of the motor A32 continues to rotate to drive the rotating rod 37 and the rotating column X35, while the collar 34 cannot rotate; thereby, the screw rod 734 rotates relative to the movable column 731, so that the slider 735 slides upward along the limiting slide groove 714, and the movable rod 736 moves upward relative to the movable straight groove 749. At this time, the closing component 74 remains in the open state until the slider 735 slides to the top of the limiting slide groove 714, as shown in 16, and the gap between the drill bit component 73 and the drill barrel A71 forms a sampling chamber;

[0072] S3,2: Drilling samples:

[0073] When the output shaft of the motor B49 is controlled to rotate by an external control mechanism, the worm 48 rotates to drive the worm ring 45 to rotate, causing the movable ring block 47 to move on the inclined guide groove 46, and the slide bar 43 slides on the centripetal groove 42. When the slide bar 43 slides to the centripetal end of the centripetal groove 42, the centripetal end of the slide bar 43 and the inner edge surface of the lower ring 41 form a rotating cavity. At this time, a plurality of plug holes 351 are plugged with a plurality of plug rods 343, and the plug rods 343 cannot be inserted into the centripetal groove 42. The output shaft of the motor A32 is controlled to rotate by an external control mechanism to drive the rotating rod 37, the rotating column X35 and the sleeve ring 34 to rotate, so that the sampling mechanism 5 rotates as a whole. The lifting mechanism 2 is controlled to descend by the external control mechanism, and part of the geological material located on the outside is led out of the ground, and the geological material located below the sampling cavity enters the sampling cavity;

[0074] S4: By adjusting, the plug rod 343 is inserted into the centripetal groove 42, and the screw rod 734 is rotated, so that the movable column 731 rotates and drives the slider 735 to rotate along the arc-shaped slide groove 715, so that the movable rod 736 drives the vertical rod 748 to rotate with the screw rod 734 as the rotation axis, so that the top ring 743 rotates, causing the gap position between the inclined groove 744 and the centripetal guide groove 742 to change, so that the guide column 747 slides along the centripetal end of the centripetal guide groove 742, driving the connecting plate 746 and the closed plate 745 to move, and the plurality of closed plates 745 rotate relative to the plurality of guide columns 747 under the interaction force, until the guide column 747 slides to the centripetal end of the centripetal guide groove 742, and the closed component 74 is constructed as follows Fig.17 The closed anti-pollution form shown prevents the sample in the sampling cavity from falling and prevents the external geological materials from contaminating the sample in the sampling cavity.

[0075] S5: The external control mechanism controls the lifting mechanism 2 to rise, bringing the sample in the sampling chamber out of the ground, adjusting so that the closing component 74 remains in an open state, adjusting so that the sampling part 7 is in a pre-drilling state, and the functional drill bit 732 pushes out the sample adhered to the sampling chamber. During this process, the worker collects geological exploration samples.
