[0017] In one embodiment of the present invention, the movable rod 13, the vertical rod 14 and the double-headed rod 15 are arranged in the same number. Figure 1 The figure shows one group. In addition to the group shown in the figure, multiple groups can be selected to be evenly distributed on the outside of the sampling tube 9, thereby improving the floating adjustment effect when the sampling tube 9 is working.

[0018] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the depth adjustment mechanism 100 includes a longitudinal slot 2, a horizontal rod 3, a driving screw 4 and a workbench 5; The horizontal rod 3 is arranged on the bracket 1, and the horizontal rod 3 is slidably connected to the longitudinal groove 2 opened on the bracket 1, and a workbench 5 is also installed at the end of the horizontal rod 3; The horizontal rod 3 is driven by a driving screw 4 installed in the bracket 1, and the bottom end of the driving screw 4 is connected to the driving motor 6 through a coupling.

[0019] In one example of the present invention, when the sampling depth of the sampling tube 9 needs to be adjusted, the drive motor 6 drives the drive screw 4 to rotate in the bracket 1. The drive screw 4 can push the horizontal rod 3 to slide along the longitudinal groove 2 during rotation, and the depth adjustment process can be changed by adjusting the direction of the drive motor 6. At the same time, the workbench 5 rises and falls synchronously with the horizontal rod 3.

[0020] like Figure 1 As shown, as another preferred embodiment of the present invention, the sampling mechanism 200 includes a driving shaft 7, a limiting groove 8, a sampling barrel 9 and a rotating motor 10; The driving shaft 7 is rotatably mounted on the workbench 5, and a sampling tube 9 is mounted on the bottom end of the driving shaft 7, and the sampling tube 9 is slidably connected with a limiting groove 8 provided on the driving shaft 7; The driving shaft 7 is driven by a rotating motor 10 installed on the workbench 5 to facilitate sampling.

[0021] In one example of the present invention, when the sampling barrel 9 is raised or lowered, the rotating motor 10 drives the drive shaft 7 and the sampling barrel 9 to rise or fall synchronously, so that the sampling barrel 9 can sample geology at different depths. In addition, when the sampling barrel 9 is subjected to force, it can also slide axially along the drive shaft 7.

[0022] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the gear drive mechanism 300 includes an L-shaped rod 11, a spur plate 12, a movable rod 13, a vertical rod 14, a double-headed rod 15, a support 16 and a gear shaft 17; The L-shaped rod 11 is fixedly mounted on the top of the bracket 1, and a straight tooth plate 12 is mounted on the inner side of the L-shaped rod 11; The movable rod 13 is arranged on the side of the workbench 5, and a vertical rod 14 is installed at the bottom end of the movable rod 13, and a double-headed rod 15 is installed at the bottom end of the vertical rod 14; A support 16 is fixedly mounted on the double-headed rod 15 , and a gear shaft 17 meshing with the spur plate 12 is rotatably mounted on the support 16 .

[0023] In one example of the present invention, when the workbench 5 is lifted or lowered, the workbench 5 also drives the side movable rod 13, the vertical rod 14 and the double-headed rod 15 to move synchronously. The double-headed rod 15 pulls the support 16 and the gear shaft 17 to move synchronously during the movement. Since the spur plate 12 is in a meshing state with the gear shaft 17, it can rotate along the support 16 when the gear shaft 17 is lifted or lowered.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the synchronous transmission unit includes a striking shaft 18, a pulley 19 and a synchronous belt 20; The striking shaft 18 is rotatably mounted on the double-headed rod 15 , and pulleys 19 are mounted on the shaft ends of the striking shaft 18 and the gear shaft 17 , and adjacent pulleys 19 are connected by a synchronous belt 20 .

[0025] In one embodiment of the present invention, when the gear shaft 17 rotates along the support 16 , the gear shaft 17 drives the side pulley 19 to rotate synchronously, and also drives the pulley 19 and the striking shaft 18 to rotate along the double-headed rod 15 through the provided synchronous belt 20 .

[0026] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the floating adjustment mechanism 400 includes a striking rod 21, a groove 22 and a movable ring 23; The movable ring 23 is slidably mounted on the end of the double-headed rod 15, and the movable ring 23 is also rotatably connected to the sampling tube 9; The striking rod 21 is fixedly mounted on the striking shaft 18, and a groove 22 for the striking rod 21 to move is provided in the double-headed rod 15; The end of the striking rod 21 is made of rubber material.

[0027] In one embodiment of the present invention, the striking rod 21 is made of rubber material and can be elastically deformed when in contact with the movable ring 23 to avoid motion interference. When the striking shaft 18 rotates along the double-headed rod 15, it also drives the striking rod 21 on the inner side of the double-headed rod 15 to rotate along the synchronous belt 20. The striking rod 21 continuously strikes the movable ring 23 while rotating with the striking shaft 18.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the floating adjustment mechanism 400 further includes a top ring 24, a bottom ring 25, a guide rod 26 and an elastic member 27; The top ring 24 is rotatably mounted on the bottom of the workbench 5, and the bottom ring 25 is fixedly mounted on the top of the sampling tube 9; A guide rod 26 is installed at the bottom end of the top ring 24, and an elastic member 27 is sleeved on the guide rod 26 to prevent the sampling tube 9 from being damaged during operation.

[0029] In one example of the present invention, when the movable ring 23 is subjected to force and transmitted to the sampling barrel 9, the sampling barrel 9 moves in the height direction, and the sampling barrel 9 also drives the bottom ring 25 to slide along the guide rod 26. During this process, the elastic member 27 is subjected to force and elastically deforms to avoid continuous collision between the sampling barrel 9 and the hard sample. In addition, when the sampling barrel 9 is rotating, the sampling barrel 9 also drives the bottom ring 25, the guide rod 26 and the top ring 24 to rotate synchronously along the workbench 5, thereby achieving the purpose of improving stability.

[0030] In summary, the rotating motor 10 drives the driving shaft 7 and the sampling tube 9 to rise and fall synchronously, so that the sampling tube 9 can sample the geology at different depths. The sampling tube 9 also drives the bottom ring 25, the guide rod 26 and the top ring 24 to rotate synchronously along the workbench 5. When the sampling depth of the sampling tube 9 needs to be adjusted, the driving motor 6 drives the driving screw 4 to rotate in the bracket 1. The driving screw 4 can push the horizontal rod 3 to slide along the longitudinal groove 2 during rotation, and the depth adjustment process can be changed by adjusting the direction of the driving motor 6. At the same time, the workbench 5 is synchronously lifted and lowered with the horizontal rod 3, and the workbench 5 also drives the side movable rod 13, the vertical rod 14 and the double-headed rod 15 to move synchronously. The double-headed rod 15 pulls the support 16 and the gear shaft 17 to move synchronously during the movement, and because the spur plate 12 is in a meshing state with the gear shaft 17, it can rotate along the support 16 when the gear shaft 17 is lifted and lowered. When the gear shaft 17 rotates along the support 16, the gear shaft 17 drives the side pulley 19 to rotate synchronously, and also drives the pulley 1 through the set synchronous belt 20 9 and the striking shaft 18 rotate along the double-headed rod 15. The striking rod 21 is made of rubber material and can be elastically deformed when in contact with the movable ring 23 to avoid motion interference. When the striking shaft 18 rotates along the double-headed rod 15, it also drives the striking rod 21 inside the double-headed rod 15 to rotate along the synchronous belt 20. The striking rod 21 continuously strikes the movable ring 23 while rotating with the striking shaft 18. When the movable ring 23 is subjected to force and transmitted to the sampling tube 9, the sampling tube 9 moves in the height direction. The sampling tube 9 also drives the bottom ring 25 along the guide The rod 26 slides, and during this process the elastic member 27 is stressed and elastically deformed to avoid continuous collision between the sampling tube 9 and the hard sample. The surface sampling and analysis equipment for mineral exploration provided by the present invention can not only adjust the sampling depth during operation, but also realize the force unloading work for the sampling tube 9, to avoid continuous direct collision between the sampling tube 9 and the hard geology due to the impact force when the sampling tube 9 is vertically drilled. Local fine adjustment can be performed when the sampling tube 9 is subjected to a large impact force during drilling, thereby achieving the purpose of protecting the bottom end of the sampling tube 9 from damage during drilling.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
