Description

Technical Field

[0001] The present invention belongs to the technical field of sampling equipment, and particularly relates to a core sampling drill for stalagmites in a karst cave and a using method thereof. Background Art

[0002] A stalagmite is a common secondary carbonate deposit formed by the precipitation of calcium carbonate from dripping water containing calcium bicarbonate and deposited at the bottom of a karst cave. By using stalagmites for high-precision uranium-thorium dating and the analysis of calcium carbonate carbon-oxygen isotopes, the climate change in the history of the earth can be understood. Using stalagmites for paleoclimate reconstruction is of great significance for past global changes and Quaternary geology, which provides a large amount of reference materials for predicting the response of the climate system under the background of future global warming. Therefore, it is particularly important to collect precious stalagmite samples in karst caves for laboratory analysis.

[0003] However, in the prior art, the sampling of stalagmites in a karst cave mainly includes methods such as manually knocking samples with a geological hammer and cutting with a diesel engine. In these methods, manual techniques are inconvenient for sampling large stalagmites, or diesel engines will cause great harm to the human body in a closed karst cave, and the damage to landscapes such as stalagmites and stalactites in the karst cave is relatively large, which is not conducive to the later tourism development of karst cave resources or the construction of geological parks.

A clamping groove is formed on the outer surface of the rotating connecting pipe. The top end of the sampling pipe is slidably inserted into the rotating connecting pipe. One end of the connecting block extends into the clamping groove.

[0014] A method for using a stalagmite sampling and core drilling rig in a karst cave includes the following steps: S1. Structure adjustment: By increasing or decreasing the number of extension rods used, the spliced extension rods, top pipes, sliding rods and bottom pipes can support the top ring higher than the top of the stalagmite to be sampled. At this time, move the position of the moving seat so that the moved moving seat can cooperate with the extension rods, top pipes, sliding rods and bottom pipes to form a temporary support point. Then, wind each connecting rope around the stalagmite to be sampled, and make one end of the connecting rope able to be hooked to itself through the hook. Then, by rotating the abutting pipe, the abutting pipe can gradually squeeze the hooked hook close to the stalagmite to be sampled, and then the rope loop formed by the connected connecting rope can be tightly sleeved on the outer surface of the stalagmite to be sampled. At this time, under the support of the abutting pipe, the support of the bottom end position of the bottom pipe can be restricted more stably, and then the support mechanism can be stably placed at the stalagmite to be sampled. Then, insert the power mechanism into the four sliding frames through the bottom frame, and at the same time insert the existing iron bolt into the positioning hole at a certain height so that the existing iron bolt can support the bottom of the bottom frame, and then the power mechanism can be temporarily stopped in the sliding frame. Then, by rotating and adjusting the limiting worm, the rotating limiting worm can drive the limiting gear to rotate in cooperation with the limiting worm wheel, and then the rotating limiting gear can cooperate with the bottom pipe and the rack to move and adjust the extension length of the sliding rod. Then, by adjusting the extension lengths of the three sliding rods and observing the state of the circular bubble level, the sliding frame can be adjusted to the vertical state. At this time, observe the falling position of the bottom of the slider, and then chisel out a slight depression at the falling position. 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 stand conveniently on the top of stalagmites to be sampled with different specifications. At the same time, under the position limitation of the sliding frame, the height of the sampling mechanism can be conveniently adjusted by lifting and lowering the grip, which is convenient for drilling operation; S2. Drilling adjustment: By squeezing the bolt, the bolt can squeeze the start switch of the drill body, enabling the drill body to start normally. At this time, insert the clamping block sleeved on the outer surface of the bolt. Then, under the extrusion of the start switch of the drill body, the clamping 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 rotary connection pipe to rotate. Then, under the position limitation of the connection block and the card slot, the rotary connection pipe can drive the sampling pipe to rotate. Subsequently, the rotating sampling pipe can drive the drill bit to rotate, enabling the rotating drill bit to cut the stalagmite to be sampled. At this time, by controlling the pulling force of the downward grip, the downward movement speed of the drill bit can be conveniently controlled. During the downward movement of the drill bit, under the position limitation of the concave part, the bottom end of the slider can limit the drill bit to maintain its original position. The stalagmite to be sampled at the center of the drill bit is gradually cut into a columnar structure. At the same time, the top end of the columnar stalagmite will squeeze the clamping strip to gradually approach the inner top surface of the drill bit. Then, under the action of the internal space of the retaining ring, the gap between the clamping strips gradually increases, enabling the top end of the columnar stalagmite to smoothly pass through the gap between the retaining ring and the clamping strip and enter the internal of the sampling pipe until the drill bit moves down to the specified depth. At this time, pull out the clamping block, so that the start switch of the drill body can squeeze the bolt to return to its original position, and then the drill body stops running. At this time, pull the grip in the reverse direction, and then the drill bit can be gradually pulled out of the cutting hole upward. During the upward movement of the drill bit, under the action of its own gravity and the friction of the columnar stalagmite, the clamping strip gradually moves towards the bottom of the retaining ring. During this process, the gap between the clamping strips gradually shrinks under the extrusion of the internal space of the retaining ring until it squeezes the outer surface of the columnar stalagmite. As the height of the drill bit continues to rise, the force of the clamping strip squeezing the outer surface of the columnar stalagmite gradually increases until the clamping strip breaks off the bottom end position of the columnar stalagmite, enabling the broken columnar stalagmite to be temporarily stored in the sampling pipe and taken out of the cutting hole together; S3. Auxiliary adjustment: Connect the sealing frame to the existing conveying pipeline, and then water resources can be continuously injected into the sealing frame through the existing conveying pipeline. Subsequently, the water resources can be injected into the sampling pipe through the liquid injection port, and then into the drill bit through the liquid guiding port at the top of the slider. Thus, the water resources can continuously flow to the rotary cutting part of the drill bit. After taking out the columnar stalagmite through the sampling pipe, rotate the limit ring away from the connecting pipe, then lift and rotate the sampling pipe, enabling the connection block to move along the inside of the card slot to the outside of the connecting pipe. At this time, the top end of the sampling pipe cooperates with the pressing piece to squeeze the limit spring, and then the sampling pipe can be conveniently separated from the connecting pipe. Then, invert the sampling pipe to increase the gap between the clamping strips, and then remove the drill bit, and then the columnar stalagmite can be conveniently taken out.

[0015] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are: (1) In the present invention, during use, by increasing or decreasing the number of extension rods used, the spliced extension rods, top pipes, sliding rods, and bottom pipes can support the top ring above the top of the stalagmite to be sampled. At this time, move the position of the moving seat so that the moved moving seat, in cooperation with the extension rods, top pipes, sliding rods, and bottom pipes, can form a temporary support point. Then, after winding each connecting rope around the stalagmite to be sampled, one end of the connecting rope can be hooked to itself through a hook. Furthermore, by rotating the abutting pipe, the abutting pipe can gradually squeeze the hooked hook closer to the stalagmite to be sampled, and then the rope loop formed by the hooked connecting rope can be tightly sleeved on the outer surface of the stalagmite to be sampled. At this time, with the support of the abutting pipe, the support limit at the bottom end of the bottom pipe can be relatively stable, and then the support mechanism can be stably placed at the stalagmite to be sampled. Then, insert the power mechanism into the four sliding frames through the bottom frame, and at the same time insert the existing iron bolt into the positioning hole at a certain height so that the existing iron bolt can support the bottom of the bottom frame, and then the power mechanism can temporarily stay in the sliding frame. Then, by rotating the adjusting limit worm, the rotating limit worm, in cooperation with the limit worm wheel, can drive the limit gear to rotate. Furthermore, the rotating limit gear, in cooperation with the bottom pipe and the rack, can move to adjust the extension length of the sliding rod. Then, by adjusting the extension lengths of the three sliding rods and observing the state of the circular bubble level, the sliding frame can be adjusted to the vertical state. At this time, observe the falling position of the bottom of the slider, and then chisel out a slight depression at the falling position. After removing the existing iron bolt, 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 stand conveniently on the top of stalagmites to be sampled with different specifications. At the same time, under the position limitation of the sliding frame, the height of the sampling mechanism can be conveniently adjusted by lifting and lowering the grip, which is convenient for drilling operations, and the device can efficiently realize its due functions.

[0016] (2) In the present invention, by squeezing the bolt, the bolt can squeeze the start switch of the drill body, enabling the drill body to start normally. At this time, the block is inserted and sleeved on the outer surface of the bolt. Then, under the extrusion of the start switch of the drill body, the 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 rotary adapter tube to rotate. Then, under the position limitation of the connecting block and the card slot, the rotary adapter tube can drive the sampling tube to rotate. Subsequently, the rotating sampling tube can drive the drill bit to rotate, enabling the rotating drill bit to cut the stalagmite to be sampled. At this time, by controlling the pulling force of the pull grip, the downward movement speed of the drill bit can be conveniently controlled. During the downward movement of the drill bit, under the position limitation of the depression, the bottom end of the slider can limit the drill bit to maintain its original position, making it easier for the drill bit to cut into the stalagmite to be sampled. This effectively prevents the drill bit from sliding when it contacts the top of the stalagmite to be sampled, ensuring the accuracy and safety of the cutting. A columnar structure is gradually cut from the stalagmite to be sampled at the center of the drill bit. At the same time, the top of the columnar stalagmite will gradually press the clamping strip closer to the inner top surface of the drill bit. Then, under the action of the internal space of the retaining ring, the gap between the clamping strips gradually increases, enabling the top of the columnar stalagmite to smoothly pass through the gap between the retaining ring and the clamping strips and enter the sampling tube. When the drill bit moves down to the specified depth, the block is removed, allowing the start switch of the drill body to squeeze the bolt back to its original position, and then the drill body stops running. At this time, the grip is pulled in the reverse direction, and the drill bit can be gradually pulled out of the cutting hole upward. During the upward movement of the drill bit, under the action of its own gravity and the friction of the columnar stalagmite, the clamping strip gradually moves towards the bottom of the retaining ring. During this process, the gap between the clamping strips gradually shrinks under the extrusion of the internal space of the retaining ring until it presses against the outer surface of the columnar stalagmite. As the height of the drill bit continues to increase, the force exerted by the clamping strip on the outer surface of the columnar stalagmite gradually increases until the clamping strip breaks off the bottom end of the columnar stalagmite. Then, the broken columnar stalagmite can be temporarily stored in the sampling tube and withdrawn from the cutting hole together, enabling the device to efficiently perform the core sampling process of the stalagmite to be sampled.

[0017] (3) In the present invention, by connecting the sealing frame with the existing conveying pipeline, it is possible to continuously inject water resources into the interior of the sealing frame through the existing conveying pipeline. Subsequently, the water resources can be injected into the sampling pipe through the liquid injection port, and then into the drill bit through the liquid guiding port at the top of the slider. As a result, the water resources can continuously flow towards the rotating cutting part of the drill bit, enabling efficient cooling of the cutting part. At the same time, it can dilute the cutting dust and reduce the damage caused by the residual crushed stones inside the drill bit to the columnar stalagmite. After the columnar stalagmite is taken out through the sampling pipe, the rotating limit ring moves away from the connecting pipe. Then, the sampling pipe is lifted and rotated, causing the connecting block to move outward along the inside of the clamping groove. At this time, the top of the sampling pipe cooperates with the pressing piece to squeeze the limit spring, enabling convenient separation of the sampling pipe from the connecting pipe. Then, the sampling pipe is inverted to increase the gap between the clamping strips, and the drill bit is removed. Subsequently, the columnar stalagmite can be conveniently taken out, enabling the device to efficiently perform the sampling process of the core. At the same time, outside the sampling work, by rotating the adjusting rod, the adjusting rod can move the moving block, causing the moving block to drive the pressing rod away from the top of the drilling rig body. At this time, the pressing rod can be conveniently pulled out of the moving block, enabling the drilling rig body to be conveniently withdrawn from above the top frame. Furthermore, it can be directly held to use the drilling rig body, effectively preventing the idle waste of the device and improving the wide application of the device in actual use.

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] Embodiment. Please refer to Figures 1 - 3 , a stalagmite sampling and coring drill in a karst cave, which is composed of a support mechanism 1, a power mechanism 2 and a sampling mechanism 3.

[0022] Specifically described as follows: Please refer to Figures 4 - 7, the support mechanism 1 includes a top ring 101, a sliding frame 102, a support component, and a limiting component. There are four sliding frames 102 in total, and the four sliding frames 102 are fixedly connected to the inner surface of the top ring 101. Four moving seats 104 are slidably sleeved on the outer surface of the top ring 101. One side of each moving seat 104 is rotatably connected to a top pipe 106. The support component is arranged on the top ring 101, and the limiting component is arranged on the support component. A positioning bolt 105 is threadedly connected to the top of each moving seat 104, and the bottom end of each positioning bolt 105 is in contact with the top of the top ring 101. A plurality of positioning holes are equidistantly formed on the outer surface of one side of each sliding frame 102, and a circular bubble level 103 is fixedly connected to the outer surface of one side of each sliding frame 102. There are three groups of support components in total. Each group of support components includes an extension rod 107, a sliding rod 108, and a bottom pipe 110. The extension rod 107 is threadedly connected to the bottom end of the corresponding top pipe 106. The sliding rod 108 is threadedly connected to the bottom end of the extension rod 107. The bottom pipe 110 is slidably sleeved on the outer surface of the sliding rod 108. A placement groove is formed on the outer surface of each sliding rod 108, and a rack 109 is inserted into each placement groove. A limiting gear 111 is rotatably connected to the outer surface of each bottom pipe 110. One end of each limiting gear 111 extends into the corresponding bottom pipe 110. Each limiting gear 111 is meshed with the corresponding rack 109. A limiting worm gear is fixedly connected to the outer surface of one side of each limiting gear 111. A limiting worm 112 is rotatably connected to the outer surface of each bottom pipe 110. Each limiting worm 112 is meshed with the corresponding limiting worm gear. There are three groups of limiting components in total. Each group of limiting components includes a resisting block 113, a connecting rope 115, a resisting pipe 114, and a hook 116. The resisting block 113 is rotatably connected to the bottom end of the corresponding bottom pipe 110. The resisting pipe 114 is threadedly connected to the outer surface of one side of the resisting block 113. The connecting rope 115 is fixedly connected to the outer surface of the resisting block 113, and one end of the connecting rope 115 slidably penetrates through the resisting pipe 114. The hook 116 is fixedly connected to one end of the connecting rope 115. By increasing or decreasing the number of extension rods 107 used, the spliced extension rods 107, top pipes 106, sliding rods 108, and bottom pipes 110 can support the top ring 101 above the top of the stalagmite to be sampled. At this time, move the position of the moving seat 104 so that the moved moving seat 104, in cooperation with the extension rod 107, top pipe 106, sliding rod 108, and bottom pipe 110, can form a temporary support point. Then, after winding each connecting rope 115 around the stalagmite to be sampled once, one end of the connecting rope 115 can be hooked to itself through the hook 116. Then, by rotating the resisting pipe 114, the resisting pipe 114 can gradually squeeze the hooked hook 116 closer to the stalagmite to be sampled, so that 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, with the support of the resisting pipe 114, the support and limitation of the position of the bottom end of the bottom pipe 110 can be relatively stable, so that the support mechanism 1 can be stably placed at the stalagmite to be sampled. Then, insert the power mechanism 2 into the four sliding frames 102 through the bottom frame 201, and at the same time insert the existing iron bolt into the positioning hole at a certain height.Enable the existing iron bolt to support the bottom of the bottom frame 201, so that the power mechanism 2 can temporarily stay in the sliding frame 102. Then, by rotating and adjusting the limit worm 112, the rotating limit worm 112 can cooperate with the limit worm wheel to drive the limit gear 111 to rotate. Further, the rotating limit gear 111 can cooperate with the bottom tube 110 and the rack 109 to move and adjust the extension length of the sliding rod 108. Then, by adjusting the extension lengths of the three sliding rods 108 and observing the state of the circular bubble level 103, the sliding frame 102 is adjusted to the vertical state. At this time, observe the falling position of the bottom of the slider 307, and then chisel out a slight depression at the falling position. After the existing iron bolt is removed, 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 stand conveniently on the tops of stalagmites of different specifications to be sampled. At the same time, under the position limitation of the sliding frame 102, the height of the sampling mechanism 3 can be conveniently adjusted by lifting and lowering the grip 202, which is convenient for drilling operations; Please refer to Figures 8 - 13, the power mechanism 2 includes a bottom frame 201, a top frame 203, a drill rig body 204, a positioning component, and a connecting component. The bottom frame 201 is slidably inserted between the interiors of four sliding frames 102. A plurality of grips 202 are fixedly connected to the bottom of the bottom frame 201. The top frame 203 is threadedly connected to the top of the bottom frame 201. The drill rig body 204 is slidably inserted into the interior of the top frame 203, and the bottom end of the drill rig body 204 slidably penetrates the bottom frame 201. The positioning component is arranged on the top frame 203, and the connecting component is arranged on the drill rig body 204. The positioning component includes a bolt 207, a clamping block 208, an adjusting rod 209, a moving block 210, and a pressing rod 211. The bolt 207 slidably penetrates the outer surface of the top frame 203. The clamping block 208 is slidably sleeved on the outer surface of the bolt 207. The adjusting rod 209 is rotatably connected to the outer surface of one side of the top frame 203. The moving block 210 is threadedly connected to the outer surface of the adjusting rod 209. The pressing rod 211 is slidably inserted into the outer surface of one side of the moving block 210, and the bottom of the pressing rod 211 is in contact with the top of the drill rig body 204. The connecting component includes a rotating connection pipe 205, a pressing piece 212, and a limiting spring 213. The rotating connection pipe 205 is fixedly connected to the output end of the drill rig body 204. The pressing piece 212 is slidably inserted into the interior of the rotating connection pipe 205. The bottom of the pressing piece 212 is in contact with the top of the sampling pipe 301. The limiting spring 213 is arranged in the interior of the rotating connection pipe 205. A clamping groove 206 is formed on the outer surface of the rotating connection pipe 205. The top end of the sampling pipe 301 is slidably inserted into the interior of the rotating connection pipe 205. One end of the connecting block 303 extends into the interior of the clamping groove 206. By squeezing the bolt 207, the bolt 207 can squeeze the start switch of the drill rig body 204, so that the drill rig body 204 can be normally started. At this time, the clamping block 208 is inserted and sleeved on the outer surface of the bolt 207. Further, under the squeezing of the start switch of the drill rig 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 rig body 204 can continuously operate. The started drill rig body 204 drives the rotating connection pipe 205 to rotate. Further, under the position limitation of the connecting block 303 and the clamping groove 206, the rotating connection pipe 205 can drive the sampling pipe 301 to rotate, and then the rotating sampling pipe 301 can drive the drill bit 308 to rotate. At the same time, in addition to the sampling work, by rotating the adjusting rod 209, the adjusting rod 209 can move the moving block 210, so that the moving block 210 can drive the pressing rod 211 away from the top of the drill rig body 204. At this time, the pressing rod 211 can be conveniently pulled out of the moving block 210, so that the drill rig body 204 can be conveniently pulled out from above the top frame 203, and then the drill rig body 204 can be directly held for use, effectively preventing the idle waste of the equipment and improving the universality of the actual use of the equipment; Please refer to Figures 14 - 18, the 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. A limiting ring 302 is threadedly connected to the outer surface of the sampling tube 301. A plurality of liquid injection ports are equidistantly arranged on the outer surface of the sampling tube 301. A connecting block 303 is fixedly connected to the outer surface of the sampling tube 301. The sealing frame 309 is rotatably connected to the outer surface of the sampling tube 301. The inside of the sealing frame 309 is communicated with the inside of the sampling tube 301 through the liquid injection ports. The drill bit 308 is threadedly connected to the bottom end of the sampling tube 301. An abutting ring 305 is embedded in the drill bit 308. A plurality of clamping bars 306 are slidably inserted into the abutting ring 305. The slider 307 is slidably inserted into the abutting ring 305. A plurality of liquid guiding ports are equidistantly arranged at the top of the slider 307. Two placing grooves are arranged on the inner wall of the sampling tube 301. A pushing bar 304 is slidably inserted into each placing groove. A plurality of jacks are equidistantly arranged on the inner wall of each placing groove. The inside of each jack is communicated with the outside of the sampling tube 301. By controlling the force of pulling down the grip 202, the downward movement speed of the drill bit 308 can be conveniently controlled. During the downward movement of the drill bit 308, under the limitation of the position of the depression, the bottom end of the slider 307 can limit the drill bit 308 to maintain its original position, so that the drill bit 308 can cut into the stalagmite to be sampled more easily, effectively preventing the drill bit 308 from sliding when it contacts the top of the stalagmite to be sampled, ensuring the accuracy and safety of cutting. A columnar structure is gradually cut from the stalagmite to be sampled at the center of the drill bit 308. At the same time, the top of the columnar stalagmite will squeeze the clamping bars 306 to gradually approach the inner top surface of the drill bit 308. Then, under the action of the inner space of the abutting ring 305, the gap between the clamping bars 306 gradually increases, so that the top of the columnar stalagmite can smoothly pass through the gap between the abutting ring 305 and the clamping bars 306 and enter 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 start switch of the drilling rig body 204 can squeeze the bolt 207 to return to its original position, and then the drilling rig body 204 stops running. At this time, the grip 202 is pulled upward in the reverse direction, and then the drill bit 308 can be gradually pulled out of the cutting hole. During the upward movement of the drill bit 308, the clamping bars 306 gradually move towards the bottom of the abutting ring 305 under the action of their own gravity and the friction of the columnar stalagmite. During this process, the gap between the clamping bars 306 gradually shrinks under the extrusion of the inner space of the abutting ring 305 until it extrudes the outer surface of the columnar stalagmite. As the height of the drill bit 308 continues to rise, the force of the clamping bars 306 extruding the outer surface of the columnar stalagmite gradually increases until the clamping bars 306 cut off the bottom end position of the columnar stalagmite, so that the cut columnar stalagmite can be temporarily stored in the sampling tube 301 and taken out of the cutting hole together, enabling the equipment to efficiently perform the core sampling process of the stalagmite to be sampled. By connecting the sealing frame 309 with the existing conveying pipeline, water resources can be continuously injected into the sealing frame 309 through the existing conveying pipeline, and then the water resources can be injected into the sampling tube 301 through the liquid injection ports, and then injected into the drill bit 308 through the liquid guiding ports at the top of the slider 307.Furthermore, it enables water resources to continuously flow to the rotary cutting area of the drill bit 308, and then can efficiently cool the cutting area. At the same time, it can dilute the cutting dust, reduce the damage to the columnar stalagmite caused by the residual crushed stones inside the drill bit 308. After the columnar stalagmite is taken out through the sampling pipe 301, the rotary limiting ring 302 moves away from the connecting pipe. Then, the sampling pipe 301 is lifted and rotated, so that the connecting block 303 can move along the inside of the card slot 206 to the outside of the connecting pipe. At this time, the top of the sampling pipe 301 cooperates with the pressing piece 212 to squeeze the limiting spring 213, and then the sampling pipe 301 can be conveniently separated from the connecting pipe. Then, the sampling pipe 301 is inverted to increase the gap between the clamping strips 306, and then the drill bit 308 is removed. Then, the columnar stalagmite can be conveniently taken out, enabling the device to efficiently sample the stone core.,

[0023] The following will detail the usage method of a stalagmite sampling and core drilling machine in a karst cave provided by an embodiment of the present invention. The usage method includes the following steps: Step 1. Structure adjustment: By increasing or decreasing the number of extension rods 107 used, the spliced extension rods 107, top pipes 106, sliding rods 108, and bottom pipes 110 can support the top ring 101 to be higher than the top of the stalagmite to be sampled. At this time, move the position of the moving seat 104 so that the moved moving seat 104 can cooperate with the extension rods 107, top pipes 106, sliding rods 108, and bottom pipes 110 to form a temporary support point. Then, wind each connecting rope 115 around the stalagmite to be sampled, and make one end of the connecting rope 115 able to hook itself through the hook 116. Then, by rotating the abutting pipe 114, the abutting pipe 114 can gradually squeeze the hooked hook 116 closer 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 abutting pipe 114, the support at the bottom end position of the bottom pipe 110 can be restricted more stably, so that the support mechanism 1 can be stably placed at the stalagmite to be sampled. Then, insert the power mechanism 2 into the four sliding frames 102 through the bottom frame 201, and at the same time insert the existing iron bolt into the positioning hole at a certain height so that the existing iron bolt can support the bottom of the bottom frame 201, so that the power mechanism 2 can be temporarily stopped in the sliding frame 102. Then, by rotating and adjusting the limit worm 112, the rotating limit worm 112 can drive the limit gear 111 to rotate in cooperation with the limit worm gear, and then the rotating limit gear 111 can move and adjust the extension length of the sliding rod 108 in cooperation with the bottom pipe 110 and the rack 109. Then, by adjusting the extension lengths of the three sliding rods 108 and observing the state of the circular bubble level 103, the sliding frame 102 is adjusted to the vertical state. At this time, observe the falling position of the bottom of the slider 307, and then chisel out a slight depression 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 to stand conveniently on the tops of stalagmites to be sampled with different specifications. At the same time, under the position restriction of the sliding frame 102, the height of the sampling mechanism 3 can be conveniently adjusted by lifting and lowering the grip 202, which is convenient for drilling operations, so that the equipment can efficiently realize its due functions; Step 2. Drilling adjustment: By squeezing the bolt 207, the bolt 207 can squeeze the start switch of the drill body 204 so that the drill body 204 can be started normally. At this time, the clamping block 208 is inserted and sleeved on the outer surface of the bolt 207. Then, under the extrusion of the start 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, thus ensuring that the drill body 204 can continue to operate. The started drill body 204 drives the rotary connection pipe 205 to rotate. Then, under the position limitation of the connection block 303 and the card slot 206, the rotary connection pipe 205 can drive the sampling pipe 301 to rotate. Then, the rotating sampling pipe 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, by controlling the force of the downward pull grip 202, the downward movement speed of the drill bit 308 can be conveniently controlled. During the downward movement of the drill bit 308, under the position limitation of the depression, the bottom end of the slider 307 can limit the drill bit 308 to maintain its original position, so that the drill bit 308 can more easily cut into 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 cutting. A columnar structure is gradually cut from the stalagmite to be sampled at the center of the drill bit 308. At the same time, the top of the columnar stalagmite will gradually squeeze the clamping strip 306 closer to the inner top surface of the drill bit 308. Then, under the action of the internal space of the retaining ring 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 retaining ring 305 and the clamping strip 306 and enter the internal part of the sampling pipe 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 start switch of the drill body 204 can squeeze the bolt 207 to return to its original position, and then the drill body 204 stops operating. At this time, the grip 202 is pulled upward in the reverse direction, and then the drill bit 308 can be gradually pulled out of the cutting hole upward. During the upward movement of the drill bit 308, the clamping strip 306 gradually moves toward the bottom of the retaining ring 305 under the action of its own gravity and the friction of the columnar stalagmite. During this process, the gap between the clamping strips 306 gradually decreases under the extrusion of the internal space of the retaining ring 305 until it squeezes the outer surface of the columnar stalagmite. As the height of the drill bit 308 continues to rise, the force of the clamping strip 306 squeezing the outer surface of the columnar stalagmite gradually increases until the clamping strip 306 breaks off the bottom position of the columnar stalagmite, so that the broken columnar stalagmite can be temporarily stored in the sampling pipe 301 and taken out of the cutting hole together, enabling the device to efficiently perform the core sampling process of the stalagmite to be sampled; Step 3. Auxiliary adjustment: Connect with the existing conveying pipeline through the sealing frame 309, so that water resources can be continuously injected into the inside of the sealing frame 309 through the existing conveying pipeline. Then, the water resources can be injected into the sampling pipe 301 through the liquid injection port, and then into the inside of the drill bit 308 through the liquid guiding port at the top of the slider 307. Thus, the water resources can continuously flow to the rotary cutting part of the drill bit 308, and then the temperature of the cutting part can be efficiently reduced. At the same time, the cutting dust can be diluted, and the damage to the columnar stalagmite caused by the residual crushed stones inside the drill bit 308 can be reduced. After the columnar stalagmite is taken out through the sampling pipe 301, the rotary limiting ring 302 is separated from the connecting pipe. Then, the sampling pipe 301 is lifted and rotated, so that the connecting block 303 can move outward along the inside of the clamping groove 206 to the outside of the connecting pipe. At this time, the top of the sampling pipe 301 cooperates with the pressing piece 212 to squeeze the limiting spring 213, so that the sampling pipe 301 can be conveniently separated from the connecting pipe. Then, the sampling pipe 301 is inverted to increase the gap between the clamping strips 306, and then the drill bit 308 is removed. Thus, the columnar stalagmite can be conveniently taken out, and the device can efficiently perform the sampling process of the rock core.

[0024] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

10. A method for using a core drill for stalagmite sampling in a karst cave, characterized in that, Applied to the stalagmite sampling and core drilling rig in the karst cave described in claim 9, it includes the following steps: S1. Structure adjustment: By increasing or decreasing the number of extension rods (107) used, the spliced extension rods (107), top pipes (106), sliding rods (108), and bottom pipes (110) can support the top ring (101) above the top of the stalagmite to be sampled. At this time, move the position of the moving seat (104) so that the moved moving seat (104) can cooperate with the extension rods (107), top pipes (106), sliding rods (108), and bottom pipes (110) to form a temporary support point. Then, wind each connecting rope (115) around the stalagmite to be sampled, and make one end of the connecting rope (115) able to hook itself through the hook (116). Then, by rotating the abutting pipe (114), the abutting pipe (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 abutting pipe (114), the support of the bottom end position of the bottom pipe (110) can be restricted more stably, so that the support mechanism (1) can be stably placed at the stalagmite to be sampled. Then, insert the power mechanism (2) into the four sliding frames (102) through the bottom frame (201). At the same time, insert the existing iron bolt into the positioning hole at a certain height so that the existing iron bolt can support the bottom of the bottom frame (201), so that the power mechanism (2) can be temporarily stopped in the sliding frame (102). Then, by rotating the adjustment limit worm (112), the rotating limit worm (112) can drive the limit gear (111) to rotate in cooperation with the limit worm wheel, and then the rotating limit gear (111) can move and adjust the extension length of the sliding rod (108) in cooperation with the bottom pipe (110) and the rack (109). Then, by adjusting the extension lengths of the three sliding rods (108) and observing the state of the circular bubble level (103), the sliding frame (102) is adjusted to the vertical state. At this time, observe the falling position of the bottom of the slider (307), and then chisel out a slight depression at the falling position. After the existing iron bolt is withdrawn, 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) to be conveniently erected on the tops of stalagmites to be sampled with different specifications. At the same time, under the position restriction of the sliding frame (102), the height of the sampling mechanism (3) can be conveniently adjusted by lifting and lowering the grip (202), which is convenient for drilling operations; S2. Drilling adjustment: By squeezing the bolt (207), the bolt (207) can squeeze the start switch of the drill body (204) so that the drill body (204) can start normally. At this time, insert the clamping block (208) sleeved outside the bolt (207). Then, under the extrusion of the start 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 rotary connection pipe (205) to rotate. Then, under the position limitation of the connecting block (303) and the card slot (206), the rotary connection pipe (205) can drive the sampling pipe (301) to rotate. Then, the rotating sampling pipe (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, by controlling the force of the downward pull grip (202), the downward movement speed of the drill bit (308) can be conveniently controlled. During the downward movement of the drill bit (308), under the position limitation of the concave part, the bottom end of the slider (307) can limit the drill bit (308) to maintain its original position. 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 top end of the columnar stalagmite will squeeze the clamping strip (306) to gradually approach the inner top surface of the drill bit (308). Then, under the action of the internal space of the retaining ring (305), the gap between the clamping strips (306) gradually increases, so that the top end of the columnar stalagmite can smoothly pass through the gap between the retaining ring (305) and the clamping strip (306) and enter the inside of the sampling pipe (301). Until the drill bit (308) moves down to the specified depth, at this time, pull out the clamping block (208) so that the start switch of the drill body (204) can squeeze the bolt (207) to return to its original position. Then, the drill body (204) stops running. At this time, pull the grip (202) in the reverse direction, and then the drill bit (308) can be gradually pulled out of the cutting hole upward. During the upward movement of the drill bit (308), the clamping strip (306) gradually moves towards the bottom of the retaining ring (305) under the action of its own gravity and the friction of the columnar stalagmite. During this process, the gap between the clamping strips (306) gradually shrinks under the extrusion of the internal space of the retaining ring (305) until it squeezes the outer surface of the columnar stalagmite. As the height of the drill bit (308) continues to rise, the force of the clamping strip (306) squeezing the outer surface of the columnar stalagmite gradually increases until the clamping strip (306) breaks off the bottom end position of the columnar stalagmite. Then, the broken columnar stalagmite can be temporarily stored in the sampling pipe (301) and taken out of the cutting hole together; S3. Auxiliary adjustment: Connect with the existing conveying pipeline through the sealing frame (309), so that water resources can be continuously injected into the inside of the sealing frame (309) through the existing conveying pipeline. Then, the water resources can be injected into the sampling pipe (301) through the liquid injection port, and then injected into the inside of the drill bit (308) through the liquid guiding port at the top of the slider (307). Thus, the water resources can continuously flow to the rotary cutting part of the drill bit (308). After taking out the columnar stalagmite through the sampling pipe (301), rotate the limit ring (302) away from the connecting pipe, and then lift and rotate the sampling pipe (301) so that the connecting block (303) can move outside the connecting pipe along the inside of the clamping groove (206). At this time, the top of the sampling pipe (301) cooperates with the pressing piece (212) to squeeze the limit spring (213), so that the sampling pipe (301) can be conveniently separated from the connecting pipe. Then, invert the sampling pipe (301) to increase the gap between the clamping strips (306), and then remove the drill bit (308), and then the columnar stalagmite can be conveniently taken out.
