[0031] Reference Figure 1-Figure 7 As shown, a sampling device suitable for mountain exploration includes a rotating handle 1, and a plurality of sections of assembleable drill rods are arranged at the bottom of the rotating handle 1. For the convenience of description, two sections are taken as an example, namely a first drill rod 2 and a second drill rod 3. The structures of the two drill rods are basically the same. A drill bit 4 is arranged at the bottom of the drill rod, and the first drill rod 2 and the second drill rod 3 are installed by fixing bolts 7, and the second drill rod 3 and the drill bit 4 are also installed by fixing bolts 7. A spiral blade 5 for excavation is arranged on the side wall of the drill rod, and the excavation direction here adopts counterclockwise rotation. It also includes:

[0032] A plurality of sampling boxes 6 are provided on each section of the drill rod, and the opening direction of the sampling boxes 6 is opposite to the screwing direction of the drill bit 4;

[0033] The sealing plate 8 is movably arranged at the opening of the sampling box 6 and is used for opening and closing the sampling box 6. A fixing frame 61 is also arranged on the top of the sampling box 6 and is used for accommodating the sealing plate 8. After the sealing plate 8 moves upward, it will enter the fixing frame 61.

[0034] The driving components are respectively arranged in the first drill rod 2 and the second drill rod 3, and are used to control the movement of the sealing plate 8. The driving components are snap-connected with each other. The driving component can be movably connected to the bottom of the rotating handle 1, mainly to allow the driving component to move up and down synchronously in the drill rod.

[0035] In one embodiment, the driving assembly includes a movable rod 21 located inside the first drill rod 2 and the second drill rod 3, the movable rods 21 can be connected by snapping, a support plate 22 is fixedly provided on the top of the movable rod 21, a connecting assembly is provided on the top of the support plate 22, and the support plate 22 is connected to the rotating handle 1 through the connecting assembly, mainly the supporting plate 22 can be moved up and down on the rotating handle 1 through the connecting assembly;

[0036] A plurality of lifting rings 81 are sleeved on the movable rod 21, and the lifting rings 81 are connected to each other through a first connecting rod 80. A second connecting rod 82 is provided on one side of the lifting ring 81, and one end of the second connecting rod 82 away from the lifting ring 81 is connected to the sealing plate 8. A clamping assembly 23 is also provided on the top of the movable rod 21, and the clamping assembly 23 is clamped on the lifting ring 81.

[0037] Initially, the sealing plate 8 is in a closed state. When sampling is required, the sealing plate 8 needs to be opened. At this time, the movable rod 21 can be moved upward, and the movable rod 21 drives the lifting ring 81 to move upward through the clamping assembly 23. At this time, the sealing plate 8 will be opened under the drive of the lifting ring 81; when it needs to be closed, the movable rod 21 is moved downward, and the movable rod 21 drives the sealing plate 8 to close downward through the lifting ring 81.

[0038] In one embodiment, a fixed sleeve 25 is provided at the bottom end of the movable rod 21, a slot is provided at the bottom of the fixed sleeve 25, a connector 31 is provided on the movable rod 21 located in the second drill rod 3, an insertion rod 32 inserted into the fixed sleeve 25 is provided on the connector 31, a limiting assembly 33 is provided on the insertion rod 32, and the insertion rod 32 is connected to the fixed sleeve 25 through the limiting assembly 33;

[0039] A groove is formed on the insert rod 32, and the limiting assembly 33 includes a limiting rod 331 movable in the groove. The top of the limiting rod 331 is arc-shaped, and the bottom is flat. One end of the limiting rod 331 is provided with a limiting spring 332 located in the groove, and the side wall of the fixed sleeve 25 is provided with a limiting hole matched with the limiting rod 331.

[0040] When installing multiple sections of drill rods, especially the installation after the second drill rod 3, the insertion rod 32 on the second drill rod 3 is inserted into the fixed sleeve 25 of the previous drill rod, and the limiting rod 331 will be squeezed by the side wall of the fixed sleeve 25 and shrink inward until it is inserted into the limiting hole, completing the fixation between the movable rods 21, so that all the movable rods 21 can be assembled into one, which is convenient for synchronous movement.

[0041] In one embodiment, a first baffle 20 is provided on the inner side wall of the first drill rod 2, and the first baffle 20 is used to block the upward movement of the lifting ring 81. A second baffle 26 is provided on the top of the inner cavity of the first drill rod 2, and the second baffle 26 is used to push the driving ring 231 to move downward. A third baffle 27 is provided on the inner wall of the movable rod 21 and the bottom of the lifting ring 81, and the third baffle 27 is used to squeeze the limiting rod 331 to make it shrink inward. A second movable groove is provided on the side wall of the movable rod 21 and the bottom of the lifting ring 81, and a second sliding rod 213 is provided in the second movable groove. The lifting ring 81 is sleeved on the second sliding rod 213, and a first return spring 214 sleeved on the second sliding rod 213 is provided at the bottom end of the lifting ring 81;

[0042] Since the movable rod 21 is installed inside, it can only be disassembled by internal means when it is disassembled. After the sealing plate 8 is fully opened, the movable rod 21 can continue to move upward. At this time, the lifting ring 81 just moves to the bottom of the first baffle 20 and is blocked, and the second baffle 26 contacts the clamping assembly 23 and is ready to open, and the limit rod 331 moves to the bottom of the third baffle 27;

[0043] Continue to move the movable rod 21 upward, the second baffle 26 starts the clamping assembly 23 to disengage the lifting ring 81, and the lifting ring 81 remains motionless under the obstruction of the first baffle 20, thereby preventing the sealing plate 8 from continuing to move upward, and the limiting rod 331 moves upward and is blocked by the third baffle 27. The third baffle 27 will squeeze the limiting rod 331 along the arc surface of the limiting rod 331 to shrink inward, thereby opening the buckles between the drill rods. At this time, the drill rods can be directly separated by loosening the fixing bolts 7.

[0044] In one embodiment, a vertical rod 211 is provided at the top of the movable rod 21, and the clamping assembly 23 includes a driving ring 231 sleeved on the vertical rod 211. A first movable groove is provided on the side wall of the movable rod 21, and a first sliding rod 212 is provided in the first movable groove.

A clamping block 233 is rotatably provided at one end of the driving rod 232 away from the driving ring 231, and a second return spring 234 sleeved on the vertical rod 211 is provided at the bottom end of the driving ring 231;

[0045] When the second baffle plate 26 pushes the driving ring 231 downward, the driving ring 231 moves downward and drives the driving rod 232 to deflect outward, thereby pushing the clamping block 233 outward, so that the clamping block 233 disengages from the lifting ring 81, and the lifting ring 81 can slide relative to the movable rod 21. Two return springs are provided to ensure that when the movable rod 21 moves downward, the driving ring 231 will remain tightly attached to the first baffle plate 20 under the elastic force of the second return spring 234 and remain motionless. At the same time, the driving ring 231 will also move upward under the elastic force of the first return spring 214, so that the driving rod 232 deflects inward, allowing the clamping block 233 to be clamped on the lifting ring 81, so that the lifting ring 81 can move together with the movable rod 21.

[0046] In one embodiment, a mounting frame 235 is fixedly provided at the bottom end of the lifting ring 81, a guide rod 236 is provided on the mounting frame 235, and a limiting slider 237 which is sleeved on the guide rod 236 is provided at the bottom end of the clamping block 233, mainly for limiting the moving direction of the clamping block 233, ensuring that the clamping block 233 can only slide in the horizontal direction, thereby detaching from the lifting ring 81.

[0047] In one embodiment, the connecting assembly includes a support rod 24 fixed on the support plate 22, and the end of the support rod 24 away from the support plate 22 passes through the first drill rod 2 and is connected to a connecting sleeve 28. A positioning rod 29 is inserted into the connecting sleeve 28, and a positioning hole matching the positioning rod 29 is opened on the rotating handle 1. By pulling the connecting sleeve 28 up and down, the connecting sleeve 28 drives all the movable rods 21 to slide through the support rod 24. After moving to the desired position, the positioning rod 29 can be inserted inward to complete the fixation.

[0048] 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.
