Its main function is to collect representative samples from ore bodies, rock formations or mineralized zones. Through the analysis and detection of samples (such as chemical composition, physical properties, structural structure, etc.), it provides key basis for judging the type, grade, reserves, distribution range and occurrence status of mineral resources. It is the basis for mineral resource evaluation, exploration planning and subsequent mining design. Drilling sampling is the main means of deep exploration. It drills deep into underground rock formations to obtain samples such as rock cores and ore cores.

[0008] An adjusting member is arranged inside the lifting frame;

[0009] Among them, after the three compression rods are rotated under force, one end thereof is embedded in the interior of the fixing groove to fix the base and the support tube.

[0010] As a preferred embodiment, the connecting piece further includes:

[0011] A mounting tube fixedly connected to the upper surface of the base;

[0036] As a preferred embodiment, the adjusting member includes:

[0037] The mounting groove is provided on the inner wall surface of the lifting frame;

[0038] A push plate is embedded in the installation groove;

[0039] The knob bolt is threadedly connected to the outer surface of the lifting frame, and one end is rotatably connected to one side of the push plate through a bearing.

[0053] Compared with the prior art, the utility model has the advantages and positive effects that:

[0054] When the base needs to be fixed to the support tube, the limit plate is pushed upward through the through hole on the lower surface of the base, driving the adjusting rod to slide along the bracket. The second spring is compressed, and the hemisphere at the upper end of the adjusting rod moves upward, pushing the support plate to slide to both sides, and the support plate drives the top plate to squeeze the spring one. When the hemisphere moves above the support plate, the spring one pushes the support plate to reset, engaging the adjusting rod to fix it. At the same time, the adjusting rod moves upward to drive the pressure rod to rotate, so that one end of it is embedded in the fixing groove on the inner wall of the support tube to achieve fixation. The limiting column outside the installation tube cooperates with the positioning groove on the inner wall of the support tube to prevent relative rotation. When releasing the fixation, the support plate is pulled away from the hemisphere, and the second spring pushes the limit plate downward, and the adjusting rod slides down to drive the pressure rod out of the fixing groove. The operation is simple, no tools are required, and the installation and disassembly efficiency is improved.

[0055] 2. According to the utility model, when the height of the lifting frame needs to be adjusted, the knob bolt is rotated to drive the push plate to move away from the support tube, and the block on the push plate is disengaged from the slot on the outer surface of the support tube. At this time, the lifting frame can move up and down along the support tube, and the limit slider on its inner wall slides along the limit slot on the outer surface of the support tube to ensure the accuracy of the moving direction. When the lifting frame moves to the appropriate height, the knob bolt is rotated in the opposite direction to push the push plate to move closer to the support tube, so that the block is embedded in the corresponding slot to fix the lifting frame. The structure has high stability and can freely adjust the height to meet different sampling needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0093] When the base 1 needs to be fixed with the support pipe 2, the external tool is inserted through the through hole 19 on the lower surface of the base 1, the limiting plate 23 is pushed upward, the limiting plate 23 drives the adjusting rod 13 to slide upward along the support 12, at this time, the spring 25 is compressed, the hemispherical body 18 at the upper end of the adjusting rod 13 moves upward, the arc surface thereof is in contact with the arc groove 26 at one end of the support plate 4 and pushes the support plate 4 to slide to both sides, the support plate 4 drives the top plate 20 to press the spring 21, so that the spring 21 accumulates elastic potential energy, until the hemispherical body 18 moves above the two support plates 4, the spring 21 pushes the two support plates 4 to reset through the top plate 20, so that the arc groove 26 at one end of the two support plates 4 is clamped on the outer surface of the adjusting rod 13, the hemispherical body 18 is fixed together with the adjusting rod 13, at the same time, when the adjusting rod 13 moves upward, the pressing rod 14 is driven to rotate about the support column 17 as the fulcrum, the connecting groove 15 on the pressing rod 14 slides along the support column 17, one end of the pressing rod 14 gradually embeds into the fixing groove 22 on the inner wall of the support pipe 2, so that the base 1 is fixed with the support pipe 2, and the limiting column 10 on the outer surface of the mounting pipe 9 is embedded into the positioning groove 11 on the inner wall of the support pipe 2, so that the relative rotation between the mounting pipe 9 and the support pipe 2 is prevented, when the fixing needs to be released, the two support plates 4 are pulled outward, the two support plates 4 are away from the hemispherical body 18, the spring 25 restores the deformation and pushes the limiting plate 23 to move downward, the adjusting rod 13 slides downward, the spring 21 restores the deformation and drives the support plate 4 and the top plate 20 to reset, at the same time, the adjusting rod 13 moves downward, the pressing rod 14 is driven to rotate reversely about the rotating shaft, so that one end of the pressing rod 14 is separated from the fixing groove 22, the fixing state of the base 1 with the support pipe 2 is released, the operation is simple, no tool is needed, and the efficiency during installation and disassembly is effectively improved.

[0094] Embodiment 2:

[0095] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , on the basis of embodiment 1, the embodiment further provides an adjusting piece arranged in the interior of the lifting stand 5, which comprises: a mounting groove 29, a push plate 30, a knob bolt 32, a clamping groove 27, a clamping block 31, a limiting sliding groove 3 and a limiting sliding block 28.

[0096] The arrangement mode of each component is as follows:

[0097] The mounting groove 29 for accommodating the push plate 30 is arranged on the inner wall surface of the lifting stand 5, which provides space for the sliding of the push plate 30.

[0098] The push plate 30 for driving the clamping block 31 to move is embedded in the interior of the mounting groove 29 and can slide along the inner wall of the mounting groove 29.

[0099] The knob bolt 32 for driving the push plate 30 to move is threadedly connected to the outer surface of the lifting frame 5, and one end is rotatably connected to one side of the push plate 30 through a bearing. By rotating the knob bolt 32, the push plate 30 can be pushed to slide in the installation groove 29.

[0100] There are multiple clamping grooves 27 for cooperating with the clamping block 31 to achieve positioning. The grooves 27 are opened on the outer surface of the support tube 2 and are evenly distributed to provide embedding positions for the clamping block 31.

[0101] There are three clamping blocks 31 for embedding in the card slot 27 to achieve fixation. They are fixedly connected to one side surface of the push plate 30 and adapted to the card slot 27. They can be embedded in or out of the card slot 27 as the push plate 30 moves.

[0102] The limiting sliding groove 3 , which is used to provide a sliding path for the limiting sliding block 28 , is formed on the outer surface of the support tube 2 and extends along the length direction of the support tube 2 .

[0103] The limiting slider 28 for limiting the moving direction of the lifting frame 5 is fixedly connected to the inner wall surface of the lifting frame 5, and its outer surface is embedded in the inner wall surface of the limiting slide groove 3. It can slide along the limiting slide groove 3 to prevent the lifting frame 5 from rotating during movement.

[0104] In this embodiment, when the height of the lifting frame 5 needs to be adjusted, the knob bolt 32 is rotated, causing it to move the push plate 30 away from the support tube 2. The block 31 on the push plate 30 then disengages from the slot 27 on the outer surface of the support tube 2. At this point, the lifting frame 5 can move up and down along the support tube 2. The limiting slider 28 on the inner wall of the lifting frame 5 slides along the limiting groove 3 on the outer surface of the support tube 2, ensuring the accuracy of the movement direction of the lifting frame 5. When the lifting frame 5 reaches the desired height, the knob bolt 32 is rotated in the opposite direction, pushing the push plate 30 toward the support tube 2, causing the block 31 to engage with the corresponding slot 27, thereby securing the lifting frame 5 on the support tube 2. This provides a high degree of structural stability and allows the height of the lifting frame 5 to be freely adjusted to meet different sampling requirements.

[0105] In addition, a battery pack can also be provided in the present application to provide electrical energy to the core drilling rig 7. The circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0106] Working principle: When it is necessary to fix the base 1 and the support tube 2, an external tool is inserted through the through hole 19 on the lower surface of the base 1 to push the limit plate 23 upward. The limit plate 23 drives the adjusting rod 13 to slide upward along the bracket 12. At this time, the spring 25 is compressed, and the hemisphere 18 at the upper end of the adjusting rod 13 moves upward accordingly. Its arc surface contacts the arc groove 26 at one end of the support plate 4 and pushes the support plate 4 to slide to both sides. The support plate 4 drives the top plate 20 to squeeze the spring 1 21, so that the spring 1 21 accumulates elastic potential energy until the hemisphere 18 moves to the top of the two support plates 4. The spring 1 21 pushes the two support plates 4 to reset through the top plate 20, so that the arc groove 26 opened at one end of the two support plates 4 is engaged with the outer surface of the adjusting rod 13, fixing the hemisphere 18 together with the adjusting rod 13. At the same time, when the adjusting rod 13 moves upward, the rotating shaft The pressure rod 14 is driven to rotate with the support column 17 as the fulcrum, and the connecting groove 15 on the pressure rod 14 slides along the support column 17. One end of the pressure rod 14 is gradually embedded in the fixing groove 22 of the inner wall of the support tube 2 to fix the base 1 and the support tube 2, and the limit column 10 on the outer surface of the mounting tube 9 is embedded in the positioning groove 11 on the inner wall of the support tube 2 to prevent the mounting tube 9 and the support tube 2 from rotating relative to each other. When the fixation needs to be released, the two support plates 4 are pulled outward, and the two support plates 4 are away from the hemisphere 18. The spring 25 restores the deformation and pushes the limit plate 23 to move downward, and the adjusting rod 13 slides down accordingly. The spring 1 21 restores the deformation and drives the support plate 4 and the top plate 20 to return to their original position. While the adjusting rod 13 moves downward, the pressure rod 14 is driven to rotate in the opposite direction through the rotating shaft, so that one end of it is disengaged from the fixing groove 22, and the fixed state of the base 1 and the support tube 2 is released.

[0107] To adjust the height of the lifting frame 5, rotate the knob bolt 32, causing it to move the push plate 30 away from the support tube 2. The block 31 on the push plate 30 then disengages from the slot 27 on the outer surface of the support tube 2. At this point, the lifting frame 5 can move up and down along the support tube 2. The limiting slider 28 on the inner wall of the lifting frame 5 slides along the limiting groove 3 on the outer surface of the support tube 2, ensuring the accurate movement direction of the lifting frame 5. When the lifting frame 5 reaches the desired height, rotate the knob bolt 32 in the opposite direction, pushing the push plate 30 toward the support tube 2, causing the block 31 to engage with the corresponding slot 27, thus securing the lifting frame 5 on the support tube 2.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
