[0026] The sampler includes two adjustment seats 4, a movable seat 9 is provided between the two adjustment seats 4, a core-taking tube 10 is provided at the upper end of the movable seat 9, and a translation driving member for pushing the core-taking tube 10 toward the wall is provided between the two adjustment seats 4;

[0027] A pair of fixed seats 6 are provided on each side of the adjustment seat 4, and the fixed seats 6 are fixedly connected to the adjustment seat 4. A horizontal guide mechanism for limiting the translation of the core barrel 10 is provided between the two adjacent fixed seats 6 in front and behind, and a first rubber suction cup 7 is provided on the side of the fixed seat 6 away from the guide rod 8.

[0028] Next, the sampling steps and the advantages of the main technical solutions are described:

[0029] When the mobile frame moves to the front of the wall marked for sampling, the first rubber suction cup 7 on the fixed seat 6 will be against the smooth wall, and the first rubber suction cup 7 will be firmly attached to the wall by squeezing out the air in the first rubber suction cup 7, and the translation drive member pushes the coring tube 10 to move closer to the wall to coring the marked point. The first rubber suction cup 7 cooperates with the positioning component to limit the mobile frame, so that the sampler can stably coring without the need for hand support and fixation, with high flexibility and saving manpower and material resources.

[0030] More specifically, a rotating shaft 14 is provided at one end of the coring barrel 10, and the rotating shaft 14 is rotatably connected to one side of the movable seat 9, and a driving assembly for controlling the rotation of the coring barrel 10 is provided on the other side of the movable seat 9. The coring barrel 10 is arranged on the side of the movable seat 9 facing the wall, that is, directly in front of the movable seat 9. When coring, the driving assembly controls the rotation of the coring barrel 10, and the coring barrel 10 grinds on the wall to open a hole for coring.

[0031] For the specific structure of the drive component, please refer to the following description.

[0032] The driving assembly includes a first gear 15, a second gear 16 and a first motor 12. The first gear 15 is sleeved on the outside of the rotating shaft 14 and is fixedly connected to the rotating shaft 14. The second gear 16 is placed under the first gear 15 and meshes with the first gear 15. The first motor 12 is installed on the side of the movable seat 9 away from the core barrel 10, and the output end of the first motor 12 is fixedly connected to the second gear 16.

[0033] comprehensive Figure 3 , the specific working mode of the driver component is:

[0034] When coring, the first motor 12 drives the second gear 16 to rotate, and the second gear 16 drives the first gear 15 to rotate by meshing with the first gear 15. Since the first gear 15 is fixed to the rotating shaft 14, and the rotating shaft 14 is fixed to the coring barrel 10, when the first gear 15 rotates, the rotating shaft 14 and the coring barrel 10 will also rotate.

[0035] For the specific structure of the translation drive member, please refer to the following description.

[0036] The translation drive component includes a screw rod 5 and a second motor 13. The screw rod 5 is placed between two adjustment seats 4. Both ends of the screw rod 5 are rotatably connected to the adjustment seats 4. The screw rod 5 passes through the movable seat 9. The screw rod 5 is threadedly connected to the movable seat 9. The second motor 13 is installed on the outside of one of the adjustment seats 4. The output end of the second motor 13 is fixedly connected to the screw rod 5.

[0037] comprehensive Figure 3 , the specific working mode of the translation drive is:

[0038] The translational drive component is a common screw transmission mechanism, which is driven by the second motor 13 to rotate the screw 5. The screw 5 is threadedly engaged with the movable seat 9 during rotation, driving the movable seat 9 to move along the rod body of the screw 5 between the two adjustment seats 4. Since the screw 5 will generate a rotational force on the movable seat 9 when cooperating with the movable seat 9, it is also necessary to use a horizontal guide mechanism to limit the translation of the movable seat 9.

[0039] For the specific structure of the horizontal guide mechanism, please refer to the following description.

[0040] The horizontal guide mechanism includes a guide rod 8 and a sliding sleeve 11. The sliding sleeve 11 is fixedly connected to both sides of the movable seat 9. The guide rod 8 is placed between two adjacent front and rear fixed seats 6. The two ends of the guide rod 8 are respectively fixedly connected to the two fixed seats 6. The sliding sleeve 11 is sleeved on the outside of the guide rod 8 and is slidably connected to the guide rod 8.

[0041] comprehensive Figure 2 and Figure 3 , the specific working mode of the horizontal guide mechanism is:

[0042] When the translation drive drives the movable seat 9 to move between the two adjustment seats 4, the sliding sleeves 11 fixed on both sides of the movable seat 9 will also move. There are four sliding sleeves 11 on both sides of the movable seat 9. The four sliding sleeves 11 are respectively sleeved on the outside of the four guide rods 8. When the movable seat 9 moves, the sliding sleeves 11 will also move. The guide rods 8 guide the movable seat 9 by cooperating with the sliding sleeves 11.

[0043] comprehensive Figure 4 , the specific structure of the mobile frame is:

[0044] The mobile frame includes a base 1, a bracket 2 is provided at the upper end of the base 1, the bracket 2 is fixedly connected to the base 1, the upper end of the bracket 2 is fixedly connected to the lower end of the adjustment seat 4, a plurality of pulleys 18 are provided at the lower end of the base 1, and an armrest 21 is provided at the upper end of the bracket 2. The armrest 21 is fixedly connected to one side of the bracket 2, and when the staff pushes the mobile frame to move, they just need to hold the armrest 21 to push the base 1.

[0045] The positioning mechanism is used to limit the movement of the base 1 to ensure that the base 1 and the bracket 2 will not shake when the coring barrel 10 is coring, thereby improving the stability of the coring work.

[0046] The specific structure of the positioning mechanism is described below.

[0047] The positioning mechanism includes bolt plates 3 arranged on both sides of the base 1, the bolt plates 3 are fixedly connected to the base 1, and the bolt plates 3 are equipped with adjustment bolts 20, which pass through the bolt plates 3 and are fixedly connected to the second rubber suction cup 19 arranged below the bolt plates 3, and the adjustment bolts 20 are threadedly connected to the bolt plates 3. When the base 1 stops moving, the adjustment bolts 20 on the bolt plates 3 are rotated downward, and the adjustment bolts 20 will push the second rubber suction cup 19 to fall, and make the core barrel 10 contact the ground, and the second rubber suction cup 19 supports the base 1, thereby limiting the base 1 from moving further.

[0048] In a better embodiment, the bracket 2 includes a plurality of columns, and two adjacent column brackets are provided with ribs 17, which are fixedly connected to the upper end of the base 1, and the two ends of the ribs 17 are fixedly connected to the columns. The ribs 17 are arranged at the upper end of the base 1, which can not only enhance the structural strength of the bracket 2, but also cooperate with the columns to enclose a placement space at the upper end of the base 1, so that the tools placed at the upper end of the base 1 will not fall when the base 1 moves.

[0049] How this application works:

[0050] When the mobile frame moves to the front of the wall marked for sampling, the first rubber suction cup 7 on the fixed seat 6 will rest against the smooth wall, and by squeezing out the air in the first rubber suction cup 7, the first rubber suction cup 7 is firmly adsorbed to the wall, and the translation drive member pushes the coring tube 10 toward the wall to coring the marked point.
