Description

Technical Field

[0001] The invention belongs to the technical field of sampling equipment, and in particular relates to a stalagmite sampling and coring drill in a cave and a use method thereof. Background Art

[0002] Stalagmites are a common secondary carbonate deposit formed by calcium carbonate precipitated from dripping water rich in calcium bicarbonate and deposited at the bottom of caves. High-precision uranium-thorium dating and carbon and oxygen isotope analysis of calcium carbonate using stalagmites can help us understand climate change in Earth's history. Paleoclimate reconstruction using stalagmites is of great significance for past global changes and Quaternary geology, providing a wealth of reference data for predicting the response of the climate system to future global warming. Therefore, it is particularly important to collect precious stalagmite samples in caves for laboratory analysis.

[0003] However, in the existing technology, the sampling of fixed stalagmites in the cave is mainly divided into two methods: manual sampling with a geological hammer and cutting with a diesel engine. Among these methods, the manual technology is not convenient for sampling large stalagmites, or the diesel engine can cause great harm to the human body in a closed cave, and is also very destructive to the stalagmites and stalactites in the cave, which is not conducive to the later tourism development of cave resources or the construction of geological parks. Therefore, there is an urgent need to develop clean and convenient stalagmite sampling and coring equipment. Summary of the Invention

[0016] A method for using a stalagmite sampling and coring drill in a cave comprises the following steps:

[0017] S1. Structural adjustment: by increasing or decreasing the number of extension rods used, the spliced ​​extension rods, top tube, sliding rod and bottom tube can support the top ring higher than the top of the stalagmite to be sampled. At this time, the position of the movable seat is moved so that the moved movable seat can cooperate with the extension rod, top tube, sliding rod and bottom tube to form a temporary support point. Then, after each connecting rope is wrapped around the stalagmite to be sampled, one end of the connecting rope can be hooked with itself through the hook. Then, by rotating the anti-tube, the anti-tube can gradually squeeze the hooked hook close to the stalagmite to be sampled, and then the rope loop formed by the hooked connecting rope can be tightly fitted on the outer surface of the stalagmite to be sampled. At this time, under the support of the anti-tube, the support limit of the bottom end of the bottom tube can be relatively stable, so that the supporting mechanism can be stably placed on the stalagmite to be sampled. Then, the power mechanism is inserted between the four sliding frames through the bottom frame, and the existing iron bolt is inserted into the positioning hole at a certain height. The cam is moved in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation so that the cam can move in a direction of rotation

[0018] S2. Drilling adjustment: by squeezing the bolt, the bolt can squeeze the starting switch of the drill rig body, so that the drill rig body can start normally. At this time, the card block is inserted into the outer surface of the card block, and then under the squeezing of the starting switch of the drill rig body, the card block can be tightly inserted between the card bolt and the outer wall of the top frame, thereby ensuring that the drill rig body can continue to operate. The started drill rig body drives the transfer tube to rotate, and then under the position limit of the connecting block and the card slot, the transfer tube can drive the sampling tube to rotate, and then the rotating sampling tube can drive the drill bit to rotate, so that the rotating drill bit can cut the stalagmite to be sampled. At this time, the downward movement speed of the drill bit can be conveniently controlled by controlling the force of pulling down the grip. In the process of the drill bit moving down, under the position limit of the recessed part, the bottom end of the slider can limit the drill bit to maintain its original position, and the stalagmite to be sampled at the center of the drill bit is gradually cut to form a columnar structure. At the same time, the top of the columnar stalagmite gradually sticks to the extrusion strip. The drill bit is then pulled back to its original position, and the start switch of the drill rig body is pulled out to press the latch bolt back to its original position, and the drill rig body stops running. At this time, the handle is pulled in the opposite direction, and the drill bit can be gradually pulled up and out of the cutting hole. In the process of the drill bit moving up, the clamping strips gradually move towards the bottom of the anti-ring under the action of their own gravity and the friction of the anti-ring. In this process, the gap between the clamping strips is gradually reduced under the pressure of the anti-ring internal space, until the outer surface of the anti-ring is squeezed. As the drill bit continues to move up, the force of the clamping strips squeezing the outer surface of the anti-ring is gradually increased, until the clamping strips cut off the bottom end of the anti-ring, and the cut anti-ring can be temporarily stored in the sampling tube and pulled out of the cutting hole together.

[0019] S3. Auxiliary adjustment: The sealing frame is connected to the existing delivery pipeline, so that water resources can be continuously injected into the sealing frame through the existing delivery pipeline, and then the water resources can be injected into the sampling tube through the liquid injection port, and then injected into the drill bit through the liquid guide port on the top of the slider, so that the water resources can continuously flow to the rotating cutting position of the drill bit. After the columnar stalagmite is taken out through the sampling tube, the rotating limit ring is moved away from the connecting tube, and the sampling tube is lifted and rotated so that the connecting block can move along the inside of the card slot to the outside of the connecting tube. At this time, the top end of the sampling tube cooperates with the pressing piece to squeeze the limit spring, so that the sampling tube and the connecting tube can be easily separated. The sampling tube is then inverted to increase the gap between the clamping strips, and the drill bit is removed, and the columnar stalagmite can be easily taken out.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) In the present invention, when in use, the number of extension rods used is increased or decreased so that the spliced ​​extension rods, top tubes, sliding rods and bottom tubes can support the top ring higher than the top of the stalagmite to be sampled. At this time, the position of the movable seat is moved so that the movable seat after movement can cooperate with the extension rods, top tubes, sliding rods and bottom tubes to form a temporary support point. Then, after each connecting rope is wrapped around the stalagmite to be sampled, one end of the connecting rope can be hooked with itself through a hook, and then, by rotating the anti-tube, the anti-tube can gradually squeeze the hooked hook close to the stalagmite to be sampled, and then the rope loop formed by the hooked connecting rope can be tightly fitted on the outer surface of the stalagmite to be sampled. At this time, under the support of the anti-tube, the support limit of the bottom end position of the bottom tube can be relatively stable, so that the supporting mechanism can be stably placed on the stalagmite to be sampled. Then, the power mechanism is inserted between the four sliding frames through the bottom frame, and at the same time, the existing iron bolt is inserted into the positioning hole of a certain height, so that the existing iron bolt The bolt can support the bottom of the bottom frame, so that the power mechanism can temporarily stay in the sliding frame, and then by rotating the adjustment limit worm, the rotating limit worm cooperates with the limit worm gear to drive the limit gear to rotate, and then the rotating limit gear cooperates with the bottom tube and the rack to move the extension length of the adjustment slide rod, and then by adjusting the extension length of the three slide rods, while observing the state of the circular bubble level, and then adjust the slide frame to a vertical state, at this time observe the falling position of the bottom of the slider, and then hammer out a slight depression in the falling position, so that after the existing iron bolt is pulled out, the falling power mechanism can drive the sampling mechanism so that the bottom of the slider can be inserted into the depression, at this time, the power mechanism can carry the sampling mechanism and conveniently erect it on the top of stalagmites of different specifications to be sampled, and at the same time, under the position limit of the slide frame, the height of the sampling mechanism can be conveniently adjusted by lifting and releasing the handle, which is convenient for drilling operation and enables the equipment to efficiently perform its functions.

[0022] (2) In the present invention, by squeezing the bolt, the bolt can squeeze the starting switch of the drill body, so that the drill body can start normally. At this time, the card block is inserted into the outer surface of the bolt, and then under the squeezing of the starting switch of the drill body, the card block can be tightly inserted between the bolt and the outer wall of the top frame, thereby ensuring that the drill body can continue to operate. The started drill body drives the transfer tube to rotate, and then under the position limit of the connecting block and the card slot, the transfer tube can drive the sampling tube to rotate, and then the rotating sampling tube can drive the drill bit to rotate, so that the rotating drill bit can cut the stalagmite to be sampled. At this time, the downward movement speed of the drill bit can be conveniently controlled by controlling the force of pulling down the handle. During the downward movement of the drill bit, under the position limit of the recess, the bottom end of the slider can limit the drill bit to maintain its original position, thereby making it easier for the drill bit to cut into the inside of the stalagmite to be sampled, effectively preventing the drill bit from sliding when it contacts the top of the stalagmite to be sampled, ensuring the accuracy and safety of the cutting, and the stalagmite to be sampled at the center of the drill bit is gradually cut to form a columnar structure. At the same time, the top of the columnar stalagmite will squeeze the clamping strip gradually close to the top surface of the drill bit, and then under the action of the internal space of the anvil, the gap between the clamping strips will gradually increase, so that the top of the columnar stalagmite can smoothly pass through the gap between the anvil and the clamping strip and enter the sampling tube until the drill bit moves down to the specified depth. At this time, the block is pulled out, so that the starting switch of the drill body can squeeze the clamping bolt to return to its original position, and the drill body stops running. At this time, the handle is pulled in the opposite direction, so that the drill bit can be gradually pulled upward to cut the hole. In the process of the drill bit moving up, The clamping strips gradually move toward the bottom of the abutment ring under the action of their own gravity and the friction of the columnar stalagmite. During this process, the gaps between the clamping strips gradually shrink under the compression of the internal space of the abutment ring until the outer surface of the columnar stalagmite is squeezed. As the drill bit height continues to rise, the force with which the clamping strips squeeze the outer surface of the columnar stalagmite gradually increases until the clamping strips cut off the bottom end of the columnar stalagmite. The cut columnar stalagmite can then be temporarily stored in the sampling tube and pulled out of the cutting hole together, so that the equipment can efficiently perform core sampling of the stalagmite to be sampled.

[0023] (3) In the present invention, the sealing frame is connected to the existing conveying pipe, and water resources can be continuously injected into the sealing frame through the existing conveying pipe, and then the water resources can be injected into the sampling tube through the liquid injection port, and then injected into the drill bit through the liquid guide port on the top of the slider, so that the water resources can continuously flow to the rotating cutting part of the drill bit, and then the cutting part can be cooled efficiently. At the same time, the cutting dust can be diluted, and the damage to the columnar stalagmite caused by the residual gravel inside the drill bit can be reduced. After the columnar stalagmite is taken out through the sampling tube, the rotating limit ring is away from the connecting tube, and then the sampling tube is lifted and rotated, so that the connecting block can move along the inside of the card slot to the outside of the connecting tube. At this time The top of the sampling tube cooperates with the pressing piece to squeeze the limit spring, so that the sampling tube can be easily separated from the connecting tube, and then the sampling tube is inverted to increase the gap between the clamping strips, and then the drill bit can be removed, and then the columnar stalagmite can be easily taken out, so that the equipment can efficiently perform stone core sampling and processing. At the same time, in addition to the sampling work, the adjusting rod can be rotated so that the adjusting rod can move the moving block, so that the moving block can drive the pressure rod away from the top of the drill rig body. At this time, the pressure rod can be easily pulled out of the moving block, so that the drill rig body can be easily pulled out from above the top frame, and then it can be used by directly holding the drill rig body, effectively preventing idle waste of equipment and improving the wide range of actual use of the equipment.

By increasing or decreasing the number of extension rods 107 used, the spliced ​​extension rods 107, the top tube 106, the sliding rod 108 and the bottom tube 110 can support the top ring 101 above the top of the stalagmite to be sampled. At this time, the position of the moving seat 104 is moved so that the moved The movable seat 104 cooperates with the extension rod 107, the top tube 106, the sliding rod 108 and the bottom tube 110 to form a temporary support point.

The level 103 is in the state, and then the slide frame 102 is adjusted to the vertical state. At this time, the falling position of the bottom of the slider 307 is observed, and then a slight depression is made at the falling position by hammering. After the existing iron bolt is pulled out, the falling power mechanism 2 can drive the sampling mechanism 3 so that the bottom of the slider 307 can be inserted into the inside of the depression. At this time, the power mechanism 2 can carry the sampling mechanism 3 and conveniently stand it on the top of the stalagmites of different sizes to be sampled. At the same time, within the position limit of the slide frame 102, the height of the sampling mechanism 3 can be conveniently adjusted by lifting and releasing the handle 202, which facilitates the drilling operation.

Under the position restriction of the card slot 206, the transfer tube 205 can drive the sampling tube 301 to rotate, and then the rotating sampling tube 301 can drive the drill bit 308 to rotate. At the same time, outside the sampling work, the adjusting rod 209 can be rotated so that the adjusting rod 209 can move the moving block 210, so that the moving block 210 can drive the pressure rod 211 away from the top of the drilling rig body 204. At this time, the pressure rod 211 can be easily pulled out of the moving block 210, so that the drilling rig body 204 can be easily pulled out from above the top frame 203, and then the drilling rig body 204 can be directly held for use, effectively preventing the idle waste of the equipment and improving the wide range of practical use of the equipment;

[0048] See also Figures 14-18The sampling mechanism 3 is arranged on the connecting component. The sampling mechanism 3 includes a sampling tube 301, a sealing frame 309, a drill bit 308 and a slider 307. The outer surface of the sampling tube 301 is threadedly connected to the limiting ring 302. The outer surface of the sampling tube 301 is equidistantly provided with a plurality of liquid injection ports. The outer surface of the sampling tube 301 is fixedly connected with a connecting block 303. The sealing frame 309 is rotatably connected to the outer surface of the sampling tube 301. The interior of the sealing frame 309 is connected to the interior of the sampling tube 301 through the liquid injection port. The drill bit 308 is threadedly connected to the bottom end of the sampling tube 301. A collar 305 is embedded in the drill bit 308. A plurality of clamping strips 306 are slidably inserted into the collar 305. The slider 307 is slidably inserted into the collar 305. A plurality of liquid guide ports are equidistantly provided on the top of the slider 307. The inner surface wall of the sampling tube 301 is provided with two first placement grooves, and a push strip 304 is slidably inserted in the interior of each first placement groove. A plurality of jacks are equidistantly provided on the inner surface wall of each first placement groove, and the interior of each jack is connected to the outside of the sampling tube 301. By controlling the force of the pull-down handle 202, the downward movement speed of the drill bit 308 can be conveniently controlled. In the process of the drill bit 308 moving downward, the bottom end of the slider 307 can limit the drill bit 308 to maintain its original position under the position restriction of the recess, so that the drill bit 308 can more easily cut into the interior of the stalagmite to be sampled, effectively preventing the drill bit 308 from sliding when contacting the top of the stalagmite to be sampled, ensuring the accuracy and safety of the cutting, and the stalagmite to be sampled at the center of the drill bit 308 is gradually cut into a columnar structure. At the same time, the columnar structure The top of the stalagmite will squeeze the clamping strip 306 gradually close to the top surface of the drill bit 308, and then under the action of the internal space of the anvil 305, the gap between the clamping strips 306 will gradually increase, so that the top of the columnar stalagmite can smoothly pass through the gap between the anvil 305 and the clamping strip 306 to enter the interior of the sampling tube 301, until the drill bit 308 moves down to the specified depth. At this time, the clamping block 208 is pulled out, so that the starting switch of the drill rig body 204 can squeeze the clamping bolt 207 to return to its original position, and the drill rig body 204 stops running. At this time, the handle 202 is pulled in the opposite direction, so that the drill bit 308 can be gradually pulled upward to cut the hole. In the process of the drill bit 308 moving upward, the clamping strip 306 gradually moves to the bottom of the anvil 305 under the action of its own gravity and the friction of the columnar stalagmite. During the drilling process, the gap between the clamping strips 306 is gradually reduced under the pressure of the internal space of the collar 305 until the outer surface of the columnar stalagmite is squeezed. As the drill bit 308 is continuously moved upward, the force of the clamping strips 306 squeezing the outer surface of the columnar stalagmite is gradually increased until the clamping strips 306 cut off the bottom end of the columnar stalagmite, and the cut columnar stalagmite can be temporarily stored in the sampling tube 301 and extracted together with the cutting hole, so that the equipment can efficiently perform the core sampling of the stalagmite to be sampled. The sealing frame 309 is connected to the existing delivery pipeline, and water resources can be continuously injected into the sealing frame 309 through the existing delivery pipeline, and then the water resources can be injected into the sampling tube 301 through the liquid injection port, and then injected into the drill bit 308 through the liquid guide port on the top of the slider 307.This allows water to continuously flow to the rotating cutting area of ​​the drill bit 308, effectively cooling the cutting area and diluting the cutting dust, thereby reducing the damage to the columnar stalagmites caused by the residual gravel inside the drill bit 308. After the columnar stalagmite is taken out through the sampling tube 301, the rotating limit ring 302 is away from the connecting tube, and the sampling tube 301 is lifted and rotated, so that the connecting block 303 can move along the inside of the card slot 206 toward the outside of the connecting tube. At this time, the top of the sampling tube 301 cooperates with the pressing piece 212 to squeeze the limit spring 213, so that the sampling tube 301 can be easily separated from the connecting tube. The sampling tube 301 is then inverted to increase the gap between the clamping strips 306, and the drill bit 308 is removed. The columnar stalagmite can then be easily taken out, so that the equipment can efficiently perform rock core sampling.

[0049] The following is a detailed description of a method for using a stalagmite sampling and coring drill in a cave provided by an embodiment of the present invention, and the method includes the following steps:

[0050] Step 1: Structural adjustment: by increasing or decreasing the number of extension rods 107, the extension rods 107, top tube 106, slide rod 108 and bottom tube 110 after splicing can support the top ring 101 higher than the top of the stalagmite to be sampled. At this time, the position of the movable seat 104 is moved so that the movable seat 104 after moving cooperates with the extension rods 107, top tube 106, slide rod 108 and bottom tube 110 to form a temporary support point. Then, each connecting rope 115 is wrapped around the stalagmite to be sampled once, so that one end of the connecting rope 115 can be hooked with itself through the hook 116. The anti-tube 114 is connected, and then by rotating the anti-tube 114, the anti-tube 114 can gradually squeeze the hooked hook 116 close to the stalagmite to be sampled, and then the rope loop formed by the hooked connecting rope 115 can be tightly sleeved on the outer surface of the stalagmite to be sampled. At this time, under the support of the anti-tube 114, the support limit of the bottom end position of the bottom tube 110 can be relatively stable, so that the support mechanism 1 can be stably placed on the stalagmite to be sampled, and then the power mechanism 2 is inserted between the four sliding frames 102 through the bottom frame 201, and the existing iron bolt is inserted into the positioning hole at a certain height. Inside, the existing iron bolt can support the bottom of the bottom frame 201, so that the power mechanism 2 can temporarily stay in the slide frame 102, and then by rotating the limit worm 112, the rotating limit worm 112 can cooperate with the limit worm wheel to drive the limit gear 111 to rotate, and then the rotating limit gear 111 can cooperate with the bottom tube 110 and the rack 109 to move the extension length of the adjustment slide rod 108, and then by adjusting the extension length of the three slide rods 108, while observing the state of the circular bubble level 103, the slide frame 10 2 is adjusted to a vertical state. At this time, the falling position of the bottom of the slider 307 is observed, and a slight depression is then hammered at the falling position. After the existing iron bolt is pulled out, the falling power mechanism 2 can drive the sampling mechanism 3 so that the bottom of the slider 307 can be inserted into the depression. At this time, the power mechanism 2 can carry the sampling mechanism 3 and conveniently stand it on the top of stalagmites of different sizes to be sampled. At the same time, within the position limit of the sliding frame 102, the height of the sampling mechanism 3 can be conveniently adjusted by lifting and releasing the handle 202, which facilitates the drilling operation and enables the equipment to efficiently perform its functions.

[0051] Step 2: Drilling adjustment: By squeezing the bolt 207, the bolt 207 can squeeze the starting switch of the drill body 204, so that the drill body 204 can start normally. At this time, the clamping block 208 is inserted and sleeved on the outer surface of the bolt 207, and then under the squeezing of the starting switch of the drill body 204, the clamping block 208 can be tightly inserted between the bolt 207 and the outer wall of the top frame 203, thereby ensuring that the drill body 204 can continue to operate. The started drill body 204 drives the transfer tube 205 to rotate, and then under the position restriction of the connecting block 303 and the card slot 206, the transfer tube 205 can drive the sampling tube 301 to rotate. , and then the rotating sampling tube 301 can drive the drill bit 308 to rotate, so that the rotating drill bit 308 can cut the stalagmite to be sampled. At this time, the downward movement speed of the drill bit 308 can be conveniently controlled by controlling the force of the pull-down handle 202. In the process of the drill bit 308 moving downward, under the position restriction of the recessed part, the bottom end of the slider 307 can restrict the drill bit 308 to maintain its original position, so that the drill bit 308 can more easily cut into the interior of the stalagmite to be sampled, effectively preventing the drill bit 308 from sliding when contacting the top of the stalagmite to be sampled, ensuring the accuracy and safety of the cutting, and the stalagmite to be sampled at the center of the drill bit 308 gradually The cutting forms a columnar structure, and at the same time, the top of the columnar stalagmite squeezes the clamping strip 306 gradually close to the inner top surface of the drill bit 308, and then, under the action of the internal space of the anvil 305, the gap between the clamping strips 306 gradually increases, so that the top of the columnar stalagmite can smoothly pass through the gap between the anvil 305 and the clamping strip 306 and enter the interior of the sampling tube 301 until the drill bit 308 moves down to the specified depth. At this time, the block 208 is pulled out, so that the starting switch of the drill body 204 can squeeze the clamping bolt 207 to return to its original position, and then the drill body 204 stops running. At this time, the handle 202 is pulled back, and the drill bit 308 can be gradually pulled upward to remove the cut hole. During the upward movement of the drill bit 308, the clamping strips 306 gradually move toward the bottom of the anvil ring 305 under the action of their own gravity and the friction of the columnar stalagmite. During this process, the gaps between the clamping strips 306 are gradually reduced under the pressure of the internal space of the anvil ring 305 until the outer surface of the columnar stalagmite is squeezed. As the drill bit 308 continues to move upward, the force with which the clamping strips 306 squeeze the outer surface of the columnar stalagmite gradually increases until the clamping strips 306 cut off the bottom end of the columnar stalagmite, and then the cut columnar stalagmite can be temporarily stored in the sampling tube 301 and extracted together with the cutting hole, so that the equipment can efficiently perform core sampling of the stalagmite to be sampled.

[0052] Step 3, auxiliary adjustment: The sealing frame 309 is connected to the existing delivery pipeline, and water resources can be continuously injected into the sealing frame 309 through the existing delivery pipeline, and then the water resources can be injected into the sampling tube 301 through the liquid injection port, and then injected into the drill bit 308 through the liquid guide port on the top of the slider 307, so that the water resources can continuously flow to the rotating cutting part of the drill bit 308, and then the cutting part can be cooled efficiently. At the same time, the cutting dust can be diluted, reducing the damage to the columnar stalagmites caused by the residual gravel inside the drill bit 308. After the columnar stalagmite is taken out through the sampling tube 301, the limiting ring 302 is rotated away from the connecting tube, and then the sampling tube 301 is lifted and rotated, so that the connecting block 303 can move along the inside of the card slot 206 toward the outside of the connecting tube. At this time, the top end of the sampling tube 301 cooperates with the pressing piece 212 to squeeze the limiting spring 213, so that the sampling tube 301 can be easily separated from the connecting tube, and then the sampling tube 301 is inverted to increase the gap between the clamping strips 306, and then the drill bit 308 is removed, and then the columnar stalagmite can be easily taken out, so that the equipment can efficiently perform stone core sampling processing.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

At this time, the position of the movable seat (104) is moved so that the movable seat (104) after being moved can form a temporary support point with the extension rods (107), top tubes (106), slide rods (108) and bottom tubes (110). After each connecting rope (115) is wrapped around the stalagmite to be sampled, one end of the connecting rope (115) can be passed through the hanging hole. The hook (116) is connected to itself, and then by rotating the anti-tube (114), the anti-tube (114) can gradually squeeze the hooked hook (116) close to the stalagmite to be sampled, and then the rope loop formed by the hooked connecting rope (115) can be tightly sleeved on the outer surface of the stalagmite to be sampled.

At this time, the falling position of the bottom of the slider (307) is observed, and then a slight depression is made in the falling position by hammering, so that after the existing iron bolt is pulled out, the falling power mechanism (2) can drive the sampling mechanism (3) so that the bottom of the slider (307) can be inserted into the inside of the depression. At this time, the power mechanism (2) can carry the sampling mechanism (3) and conveniently stand it on the top of the stalagmite to be sampled of different specifications. At the same time, under the position limit of the slide frame (102), the height of the sampling mechanism (3) can be conveniently adjusted by lifting and releasing the handle (202), so as to facilitate the drilling operation; S2, drilling adjustment: by squeezing the bolt (207), the bolt (207) can squeeze the start switch of the drilling rig body (204), so that the drilling rig body (204) can start normally, at this time, the card block (208) is inserted into the outer surface of the bolt (207), and then under the squeezing of the start switch of the drilling rig body (204), the card block (208) can be tightly inserted between the bolt (207) and the outer wall of the top frame (203), thereby ensuring that the drilling rig body (204) can continue to operate, and the started drilling rig body (204) drives the transfer tube (205) to rotate, and then the connection block (303) and the card slot (206) are connected. Under the position restriction, the transfer tube (205) can drive the sampling tube (301) to rotate, and then the rotating sampling tube (301) can drive the drill bit (308) to rotate, so that the rotating drill bit (308) can cut the stalagmite to be sampled. At this time, the downward movement speed of the drill bit (308) can be conveniently controlled by controlling the force of the pull-down handle (202). During the downward movement of the drill bit (308), under the position restriction of the recess, the bottom end of the slider (307) can limit the drill bit (308) to maintain its original position, and the stalagmite to be sampled at the center of the drill bit (308) is gradually cut to form a columnar structure, and at the same time, the top of the columnar stalagmite is The clamping strip (306) is squeezed and gradually approaches the inner top surface of the drill bit (308), and then under the action of the internal space of the collar (305), the gap between the clamping strips (306) is gradually increased, so that the top of the columnar stalagmite can smoothly pass through the gap between the collar (305) and the clamping strip (306) to enter the interior of the sampling tube (301), until the drill bit (308) moves down to the specified depth. At this time, the card block (208) is pulled out, so that the start switch of the drill body (204) can squeeze the card bolt (207) to return to its original position, and the drill body (204) stops running.
