Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a geological exploration device for mining areas and its usage method. Background Technology

[0002] Geological exploration involves investigating and exploring geology using various means and methods. It is the discovery of industrially significant mineral deposits during mineral prospecting, and the provision of mineral reserves and geological data necessary for mine construction design to ascertain the quality and quantity of minerals and the technical conditions for their exploitation. During the geological exploration process, sampling and analysis of geological strata are required. The ultimate goal of geological exploration is to provide the necessary geological data, such as mineral resources / reserves and mining technology conditions, for mine construction design, in order to reduce development risks and obtain maximum economic benefits.

[0003] In geological exploration, it is necessary to sample and analyze underground soil. Most existing geological exploration equipment samples soil by drilling into the ground. However, when the drill bit encounters hard rocks, it is easily damaged due to the lack of a buffer zone, which affects the lifespan of the drill bit. At the same time, most existing geological exploration equipment can only perform single sampling, and cannot sample and store soil at different depths separately. This makes the sampling relatively limited and may affect the accuracy of geological exploration. Improvements are needed. Summary of the Invention

[0011] As a further preferred embodiment of this technical solution: the rotating disk has a toothed groove on its side wall, and a tooth is movably installed on one side wall of the inner sleeve. A spring is connected to one side of the tooth, and the spring is fixedly connected to the inner wall of the inner sleeve. The tooth matches the toothed groove.

[0012] As a further preferred embodiment of this technical solution: the spraying mechanism includes water storage tanks fixedly installed on both sides of the upper surface of the base, piston cylinders are installed on both sides of the lower surface of the lifting seat, a piston plate is provided inside the piston cylinder, a piston rod is fixedly installed on the lower surface of the piston plate, a push-pull plate is fixedly connected to the bottom end of the piston rod, an annular seat is sleeved on the side wall of the outer cylinder, and the push-pull plate is rotatably connected to the annular seat.

[0013] As a further preferred embodiment of this technical solution: both the input and output ends of the piston cylinder are equipped with one-way valves; the input end of the piston cylinder is connected to a water suction pipe, one end of which is connected to the inside of the water storage tank; the output end of the piston cylinder is connected to a drain pipe, one end of which is connected to a nozzle, which faces the side wall of the outer cylinder.

[0014] A method for using a geological exploration device for mining areas includes the following steps:

[0015] Step 1: Using the casters at the bottom of the base, move the entire device to the location where sampling is required. Use the first drive motor to drive the rotating shaft to rotate in the forward direction, so that the rotating shaft drives the inner sleeve and outer cylinder to rotate in the forward direction synchronously, and the drill bit to rotate synchronously. At the same time, start the second drive motor to drive the transmission screw to rotate, the screw nut moves down and drives the lifting seat to move down synchronously, so that the sampling cylinder and the drill bit rotate and move down synchronously and drill into the ground below the surface.

[0016] Step 2: As the shaft rotates, the first spherical protrusion repeatedly abuts against the second spherical protrusion, which can perform short-distance reciprocating up-and-down shaking while the drill bit rotates and moves downward, providing buffer protection for the drill bit;

[0017] Step 3: During the rotation of the outer cylinder, the piston rod is pushed and pulled back and forth by the push-pull plate. Water from the water tank is drawn into the piston cylinder through the suction pipe. When the push-pull plate pushes the piston rod upward, the water is squeezed out and sprayed onto the outer wall of the outer cylinder through the nozzle, so that it flows to the drill bit to cool and lubricate it.

[0018] Step 4: When a certain depth is reached and sampling is required, the second drive motor stops working, and the first drive motor rotates in the opposite direction and drives the inner sleeve to rotate in the opposite direction through the rotating shaft; at the same time, the teeth engage with the tooth groove, and the teeth push the rotating disk to rotate in the opposite direction. When the inner sleeve rotates in the opposite direction by 45 degrees, the rotating disk rotates in the opposite direction by 45 degrees simultaneously, so that any sample cup is located at the second opening. At this time, the outer arc surface of the arc-shaped soil-pulling plate abuts against the abutting block, and one end of the arc-shaped soil-pulling plate contacts the inner wall of the borehole. During the continuous reverse rotation, soil-pulling and sampling work is carried out, and the extracted soil sample is sent into the inner sleeve through the second opening and into the corresponding sample cup.

[0019] Step 5: After sampling, the first drive motor rotates forward again, while the second drive motor continues to work, and the drill bit continues to move downward. When the inner sleeve and outer cylinder rotate forward synchronously, the teeth separate from the tooth groove, and the rotating disk is stationary relative to the outer and inner cylinders. When the drill bit descends to a certain depth and sampling is required again, the operation of step 4 is repeated.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention, by setting up a reciprocating shaking mechanism, allows the inner sleeve to rotate forward using a drive motor, which in turn drives the outer sleeve to rotate synchronously. Simultaneously, the first and second spherical protrusions abut against each other, and the compression spring is compressed, causing the inner sleeve and outer sleeve to move downwards, while the drill bit moves downwards synchronously. When the first and second spherical protrusions separate, the compression spring pushes the inner sleeve upwards, while the outer sleeve and drill bit move upwards synchronously. This reciprocating up-and-down shaking action provides buffer protection for the drill bit, preventing it from being unable to perform buffered drilling when encountering hard rocks, thus avoiding drill bit damage and effectively extending the service life of the drill bit.

[0022] 2. This invention, by setting up a spraying mechanism, allows the outer cylinder and inner sleeve to reciprocate up and down synchronously. The ring seat drives the push-pull plate to move up and down synchronously. As the push-pull plate moves up and down, it also drives the piston plate and piston rod to reciprocate up and down. This allows water in the water storage tank to be absorbed through the suction pipe and sent into the piston cylinder. The water is then sprayed onto the side wall of the outer cylinder through the drain pipe and nozzle, and flows down to cool and lubricate the drill bit. This effectively protects the drill bit and extends its service life.

[0023] 3. This invention uses an arc-shaped soil-removing plate connected to the outer cylinder via a torsion spring shaft. When the outer cylinder rotates synchronously with the inner sleeve in the forward direction, the outer arc surface of the arc-shaped soil-removing plate contacts and is compressed against the inner wall of the borehole. When the outer cylinder rotates in the reverse direction with the inner sleeve, one side of the arc-shaped soil-removing plate abuts against the abutting block, and one end of the arc-shaped soil-removing plate contacts the inner wall of the borehole to perform soil removal and sampling. The sampled soil is then fed into the inner sleeve through the second opening.

[0024] 4. This invention, through the setting of a sample storage mechanism, when the inner sleeve rotates in the reverse direction, the inner sleeve rotates 45 degrees in the reverse direction, and the toothed teeth engage with the toothed groove, pushing the rotating disk to rotate 45 degrees in the reverse direction, so that any one of the sample storage cups is located at the second opening, which facilitates the collection of soil samples; when the inner sleeve rotates in the forward direction, the toothed teeth separate from the toothed groove, and the sample storage cup and the rotating disk do not rotate. When the inner sleeve rotates 45 degrees in the reverse direction again, the sample storage cup and the rotating disk also rotate 45 degrees, at which point another empty sample storage cup is located at the second opening for sample storage. This process can be repeated to separate and store soil samples collected at different depths, which can improve the sampling accuracy. Attached Figure Description

[0035] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0036] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, a geological exploration device for a mining area includes a base 1. A support column is fixedly installed on one side of the upper surface of the base 1, and a transmission screw 3 is rotatably installed on the other side of the upper surface of the base 1. A screw nut 20 is provided on the transmission screw 3. A lifting seat 2 is provided above the base 1, and the lifting seat 2 is slidably sleeved on the support column. The screw nut 20 passes through the lifting seat 2 and is fixedly connected to the lifting seat 2. A second drive motor 7 is provided on the base 1. A drive gear 9 is fixedly connected to the output shaft of the second drive motor 7. A driven gear 8 is meshed on one side of the drive gear 9, and the driven gear 8 is fixedly sleeved on the transmission screw. 3. The lifting seat 2 is equipped with a first drive motor 6. A sampling cylinder is rotatably installed below the lifting seat 2. The sampling cylinder includes an outer cylinder 5 and an inner sleeve 19. The top of the outer cylinder 5 is rotatably connected to the lower surface of the lifting seat 2. A drill bit 4 is fixedly installed at the bottom of the outer cylinder 5. The output shaft of the first drive motor 6 is fixedly connected to a rotating shaft 16. One end of the rotating shaft 16 extends into the inner sleeve 19 and is slidably connected to the inner sleeve 19. A reciprocating shaking mechanism is provided between the inner sleeve 19 and the lifting seat 2. A sample storage mechanism is provided inside the inner sleeve 19. A spraying mechanism for cooling the drill bit 4 is provided below the lifting seat 2.

[0039] The reciprocating vibration mechanism includes a first spherical protrusion 24 fixedly installed at the top of the inner sleeve 19, a second spherical protrusion 25 fixedly installed on the lower surface of the lifting seat 2, the first spherical protrusion 24 and the second spherical protrusion 25 intermittently abutting, a sleeve 32 fixedly connected to the middle of the top of the inner sleeve 19, a slider 30 fixedly installed on the inner wall of the sleeve 32, a groove 31 matching the slider 30 opened on the side wall of the rotating shaft 16, a fixing plate 28 fixedly installed on the rotating shaft 16, and a compression spring 29 installed between the fixing plate 28 and the bottom end of the sleeve 32;

[0040] An upper annular stop 27 and a lower annular stop 37 are fixedly installed on the inner wall of the outer cylinder 5. The upper annular stop 27 and the lower annular stop 37 are respectively in contact with the top and bottom of the inner sleeve 19. A fixed ring seat 12 is fixedly installed on the lower surface of the lifting seat 2. An annular slide 26 is slidably installed inside the fixed ring seat 12. The top of the outer cylinder 5 is rotatably connected to the annular slide 26.

[0041] During operation, the entire device can be moved to the sampling location using the casters at the bottom of the base 1. Then, the first drive motor 6 drives the rotating shaft 16 to rotate forward, causing the inner sleeve 19 to rotate synchronously in the forward direction. At this time, the first stop block 22 and the second stop block 23 abut against each other, allowing the inner sleeve 19 to drive the outer cylinder 5 to rotate synchronously in the forward direction, and causing the drill bit 4 to rotate synchronously. Simultaneously, the second drive motor 7 is started to drive the drive gear 9 to rotate. The drive gear 9 meshes with the driven gear 8, causing the transmission screw 3 to rotate, and causing the screw nut 20 to move downward. At the same time, the downward movement of the screw nut 20 drives the lifting seat 2 to move downward synchronously, allowing the sampling cylinder and the drill bit 4 to rotate and move downward synchronously and drill into the ground. Simultaneously, the first drive motor 6 drives the outer cylinder 5 to rotate synchronously in the forward direction, causing the drill bit 4 to rotate. A spherical protrusion 24 reciprocates against a second spherical protrusion 25. When the first spherical protrusion 24 and the second spherical protrusion 25 are in contact, the inner sleeve 19 moves down along the slide groove 31 via the slider 30. At the same time, the compression spring 29 is compressed and contracted, and the inner sleeve 19 drives the outer cylinder 5 to move down synchronously, thereby causing the drill bit 4 to move down. When the first spherical protrusion 24 and the second spherical protrusion 25 separate, the compression spring 29 pushes the inner sleeve 19 to move up and reset, thereby causing the outer cylinder 5 and the drill bit 4 to move up and reset synchronously. Therefore, while the drill bit 4 rotates and moves down, it can perform short-distance reciprocating up and down shaking, providing buffer protection for the drill bit 4 and preventing the drill bit 4 from being unable to perform buffer drilling when encountering hard rocks, thus avoiding the phenomenon of the drill bit 4 being damaged. This effectively extends the service life of the drill bit 4.

[0042] Example 2

[0043] like Figure 2 , Figure 4 , Figure 5 and Figure 9The outer cylinder 5 has a second opening 17 on one side wall, and the inner sleeve 19 has a first opening 15 on one side wall. The first opening 15 and the second opening 17 are staggered. Two first blocks 22 are fixedly installed at the top of the inner sleeve 19. The two first blocks 22 are located on the two sides above the first opening 15. Two second blocks 23 are protruding on the inner wall of the outer cylinder 5. The two second blocks 23 are located on the two sides above the second opening 17. The first blocks 22 and the second blocks 23 are in contact. An arc-shaped soil-removing plate 39 is provided on the side wall of the outer cylinder 5. The arc-shaped soil-removing plate 39 is located on one side of the second opening 17. The arc-shaped soil-removing plate 39 is movably connected to the outer cylinder 5 through a torsion spring shaft. An abutment block 40 is provided on one side of the arc-shaped soil-removing plate 39. The abutment block 40 is fixedly installed on the side wall of the outer cylinder 5 and is in contact with the outer arc surface of the arc-shaped soil-removing plate 39.

[0044] During operation, when the outer cylinder 5 rotates synchronously with the inner sleeve 19 in the forward direction, the outer arc surface of the arc-shaped soil-removing plate 39 contacts and is squeezed against the inner wall of the borehole. When the inner sleeve 19 rotates in the reverse direction, the first stop 22 and the second stop 23 separate. When the inner sleeve 19 rotates 45 degrees in the reverse direction, the second opening 17 connects with the first opening 15. At this time, the other first stop 22 abuts against the second stop 23. The outer cylinder 5 rotates synchronously with the inner sleeve 19. At this time, the outer arc surface of the arc-shaped soil-removing plate 39 abuts against the abutting block 40. One end of the arc-shaped soil-removing plate 39 contacts the inner wall of the borehole. During the continuous reverse rotation, soil sampling is carried out, and the sampled soil is sent into the inner sleeve 19 through the second opening 17.

[0045] Example 3

[0046] like Figure 2 , Figure 6 , Figure 7 and Figure 9 As shown, the sample storage mechanism includes a rotating disk 38, with a fixed column 36 fixedly installed at the bottom of the rotating disk 38. The fixed column 36 is rotatably connected to the bottom of the inner cylinder 5 via a bearing. Multiple sample cups 18 are arranged in a fan shape on the rotating disk 38. The side wall of the rotating disk 38 is provided with a toothed groove 35. A toothed tooth 34 is movably installed on one side wall of the inner sleeve 19. A spring piece 33 is connected to one side of the toothed tooth 34. The spring piece 33 is fixedly connected to the inner wall of the inner sleeve 19. The toothed tooth 34 matches the toothed groove 35.

[0047] During operation, when the inner sleeve 19 begins to rotate in the reverse direction, the first stop 22 and the second stop 23 first separate. Simultaneously, the tooth 34 engages with the tooth groove 35, pushing the rotating disk 38 to rotate in the reverse direction. When the inner sleeve 19 rotates 45 degrees in the reverse direction, the rotating disk 38 rotates 45 degrees in the reverse direction synchronously, so that any sample cup 18 is located at the second opening 17, which is connected to the first opening 15. At this time, the other first stop 22 abuts against the second stop 23, and the outer cylinder 5 rotates in the reverse direction synchronously with the inner sleeve 19. The rotating disk 38 then moves synchronously with both the outer and inner cylinders. Therefore, the rotating disk 38 is relatively... When the outer cylinder 5 and the inner cylinder are stationary, when the inner sleeve 19 and the outer cylinder 5 rotate synchronously in the forward direction, the tooth 34 separates from the tooth groove 35, and the rotating disk 38 moves synchronously with the outer cylinder 5 and the inner cylinder. Therefore, the rotating disk 38 is stationary relative to the outer cylinder 5 and the inner cylinder. When the inner sleeve 19 rotates 45 degrees in the reverse direction again, the rotating disk 38 rotates 45 degrees in the reverse direction synchronously and is stationary relative to the outer cylinder 5 and the inner cylinder. At this time, another empty sample cup 18 is located at the second opening 17 to store the sample. This process can be repeated to separate and store soil samples collected at different depths, which is convenient for improving the sampling accuracy.

[0048] Example 4

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the spraying mechanism includes water storage tanks 10 fixedly installed on both sides of the upper surface of the base 1, piston cylinders 13 installed on both sides of the lower surface of the lifting seat 2, piston plates are provided inside the piston cylinders 13, piston rods are fixedly installed on the lower surface of the piston plates, and push-pull plates 21 are fixedly connected to the bottom end of the piston rods. An annular seat 11 is fitted on the side wall of the outer cylinder 5, and the push-pull plate 21 is rotatably connected to the annular seat 11. One-way valves are provided at both the input and output ends of the piston cylinders 13. A water suction pipe 14 is connected to the input end of the piston cylinders 13, one end of which is connected to the inside of the water storage tank 10. A drain pipe is connected to the output end of the piston cylinders 13, and a nozzle is connected to one end of the drain pipe, with the nozzle facing the side wall of the outer cylinder 5.

[0050] During operation, when the outer cylinder 5 rotates and vibrates up and down, when the outer cylinder 5 moves downward, it will drive the piston rod downward through the push-pull plate 21, thereby creating a negative pressure inside the piston cylinder 13. Water from the water storage tank 10 will be drawn into the piston cylinder 13 through the water suction pipe 14. When the outer cylinder 5 moves upward, the push-pull plate 21 will push the piston rod upward, squeezing out the water inside the piston cylinder 13. The squeezed water will be sprayed onto the outer wall of the outer cylinder 5 through the nozzle, allowing it to flow onto the drill bit 4, cooling and lubricating the drill bit 4 and increasing its service life.

[0051] Example 5

[0052] A method for using a geological exploration device for mining areas includes the following steps:

[0053] Step 1: Using the casters at the bottom of the base 1, move the entire device to the location where sampling is required. Use the first drive motor 6 to drive the rotating shaft 16 to rotate in the forward direction, so that the rotating shaft 16 drives the inner sleeve 19 and the outer cylinder 5 to rotate in the forward direction synchronously, and the drill bit 4 to rotate synchronously. At the same time, start the second drive motor 7 to drive the transmission screw 3 to rotate, the screw nut 20 moves down and drives the lifting seat 2 to move down synchronously, so that the sampling cylinder and the drill bit 4 rotate and move down synchronously and drill into the ground below the surface.

[0054] Step 2: As the shaft 16 rotates, the first spherical protrusion 24 reciprocates against the second spherical protrusion 25, which can perform short-distance reciprocating up-and-down shaking while the drill bit 4 rotates and moves down, providing buffer protection for the drill bit 4;

[0055] Step 3: When the outer cylinder 5 rotates and shakes up and down, the piston rod will be pushed and pulled back and forth by the push-pull plate 21. The piston cylinder 13 draws water from the water storage tank 10 into the piston cylinder 13 through the water suction pipe 14. When the push-pull plate 21 pushes the piston rod up, the water is squeezed out and sprayed onto the outer wall of the outer cylinder 5 through the nozzle, so that it flows to the drill bit 4 to cool and lubricate the drill bit 4.

[0056] Step 4: When a certain depth is reached and sampling is required, the second drive motor 7 stops working, the first drive motor 6 rotates in the opposite direction and drives the inner sleeve 19 to rotate in the opposite direction through the rotating shaft 16; at the same time, the tooth 34 engages with the tooth groove 35, and the tooth 34 pushes the rotating disk 38 to rotate in the opposite direction. When the inner sleeve 19 rotates in the opposite direction by 45 degrees, the rotating disk 38 rotates in the opposite direction by 45 degrees, so that any sample cup 18 is located at the second opening 17. At this time, the outer arc surface of the arc-shaped soil-pulling plate 39 abuts against the abutment block 40, and one end of the arc-shaped soil-pulling plate 39 contacts the inner wall of the borehole. During the continuous reverse rotation, soil-pulling and sampling work is carried out, and the sampled soil is sent into the inner sleeve 19 through the second opening 17 and into the corresponding sample cup 18.

[0057] Step 5: After sampling, the first drive motor 6 rotates forward again, while the second drive motor 7 continues to work, and the drill bit 4 continues to move downward. When the inner sleeve 19 and the outer cylinder 5 rotate forward synchronously, the tooth 34 separates from the tooth groove 35, and the rotating disk 38 is stationary relative to the outer cylinder 5 and the inner cylinder. When the drill bit 4 descends to a certain depth and needs to be sampled again, the operation of step 4 is repeated.

[0058] Working principle: The entire device can be moved to the sampling location using the casters at the bottom of the base 1. Then, the first drive motor 6 drives the rotating shaft 16 to rotate forward, which in turn drives the inner sleeve 19 to rotate forward synchronously. At this time, the first stop block 22 and the second stop block 23 abut against each other, which allows the inner sleeve 19 to drive the outer cylinder 5 to rotate forward synchronously, and the drill bit 4 to rotate synchronously. Simultaneously, the second drive motor 7 is started to drive the drive gear 9 to rotate. The drive gear 9 meshes with the driven gear 8 to rotate, which causes the transmission screw 3 to rotate and the screw nut 20 to move downward. At the same time, the screw nut 20 moves downward, which drives the lifting seat 2 to move downward synchronously. This allows the sampling cylinder and the drill bit 4 to rotate and move downward synchronously and drill into the ground. While rotating, the first drive motor 6 drives the inner sleeve 19 to rotate forward, and the drill bit 4 to rotate downward synchronously, and the drill bit 4 to rotate downward synchronously. A spherical protrusion 24 reciprocates against a second spherical protrusion 25. When the first spherical protrusion 24 and the second spherical protrusion 25 are in contact, the inner sleeve 19 moves down along the slide groove 31 via the slider 30. At the same time, the compression spring 29 is compressed and contracted, and the inner sleeve 19 drives the outer cylinder 5 to move down synchronously, thereby causing the drill bit 4 to move down. When the first spherical protrusion 24 and the second spherical protrusion 25 separate, the compression spring 29 pushes the inner sleeve 19 to move up and reset, thereby causing the outer cylinder 5 and the drill bit 4 to move up and reset synchronously. Therefore, while the drill bit 4 rotates and moves down, it can perform short-distance reciprocating up and down shaking, providing buffer protection for the drill bit 4 and preventing the drill bit 4 from being unable to perform buffer drilling when encountering hard rocks, thus avoiding the phenomenon of the drill bit 4 being damaged and effectively extending the service life of the drill bit 4.

[0059] When the outer cylinder 5 rotates and vibrates up and down, when the outer cylinder 5 moves down, it will drive the piston rod to move down through the push-pull plate 21, thereby creating a negative pressure inside the piston cylinder 13. Water from the water storage tank 10 will be drawn into the piston cylinder 13 through the suction pipe 14. When the outer cylinder 5 moves up, it will push the piston rod up through the push-pull plate 21, squeezing out the water inside the piston cylinder 13. The squeezed water will be sprayed onto the outer wall of the outer cylinder 5 through the nozzle, so that it flows down to the drill bit 4 to cool and lubricate the drill bit 4 and increase its service life.

[0060] When a certain depth is reached and sampling is required, the second drive motor 7 stops working, and the first drive motor 6 rotates in the opposite direction and drives the inner sleeve 19 to rotate in the opposite direction through the rotating shaft 16.

[0061] When the inner sleeve 19 starts to rotate in the reverse direction, the first stop 22 and the second stop 23 separate. At the same time, the tooth 34 engages with the tooth groove 35. The tooth 34 pushes the rotating disk 38 to rotate in the reverse direction. When the inner sleeve 19 rotates 45 degrees in the reverse direction, the rotating disk 38 rotates 45 degrees in the reverse direction synchronously, so that any one of the sample cups 18 is located at the second opening 17. The second opening 17 is connected to the first opening 15. At this time, the other first stop 22 abuts against the second stop 23. The outer cylinder 5 rotates in the reverse direction synchronously with the inner sleeve 19. At this time, the outer arc surface of the arc-shaped soil-pulling plate 39 abuts against the abutting block 40. One side of the arc-shaped soil-pulling plate 39 contacts the inner wall of the borehole. Soil-pulling and sampling work is carried out during the continuous reverse rotation. At this time, the rotating disk 38 moves synchronously with the outer cylinder 5 and the inner cylinder. Therefore, the rotating disk 38 is stationary relative to the outer cylinder 5 and the inner cylinder. The sample soil can be sent into the inner sleeve 19 through the second opening 17 and into the corresponding sample cup 18.

[0062] After sampling, the first drive motor 6 rotates forward again, while the second drive motor 7 continues to work and the drill bit 4 continues to move downward. When the inner sleeve 19 and the outer cylinder 5 rotate forward synchronously, the tooth 34 separates from the tooth groove 35, and the rotating disk 38 moves synchronously with the outer cylinder 5 and the inner cylinder. Therefore, the rotating disk 38 is stationary relative to the outer cylinder 5 and the inner cylinder.

[0063] When the drill bit 4 descends to a certain depth and needs to be sampled again, the second drive motor 7 stops working, the first drive motor 6 rotates in the opposite direction, and when the inner sleeve 19 rotates in the opposite direction by 45 degrees again, the rotating disk 38 rotates in the opposite direction by 45 degrees in sync and is stationary relative to the outer cylinder 5 and the inner cylinder. At this time, another empty sample cup 18 is located at the second opening 17 to store the sample. This process can be repeated to separate and store soil samples collected at different depths, which is convenient for storing soil samples collected at different depths and has high sampling accuracy.

9. A method of using a geological exploration device for mining areas based on any one of claims 1-8, characterized in that, Includes the following steps: Step 1: Using the movable wheels at the bottom of the base (1), move the entire device to the place where sampling is required. Use the first drive motor (6) to drive the rotating shaft (16) to rotate in the forward direction, so that the rotating shaft (16) drives the inner sleeve (19) and the outer cylinder (5) to rotate in the forward direction synchronously, and the drill bit (4) to rotate synchronously. At the same time, start the second drive motor (7) to drive the transmission screw (3) to rotate, the screw nut (20) moves down and drives the lifting seat (2) to move down synchronously, so that the sampling cylinder and the drill bit (4) rotate down synchronously and drill into the ground below the surface. Step 2: While the shaft (16) rotates, the first spherical protrusion (24) repeatedly abuts against the second spherical protrusion (25). As the drill bit (4) rotates and moves down, it performs short-distance reciprocating up and down shaking to provide buffer protection for the drill bit (4). Step 3: When the outer cylinder (5) vibrates up and down during rotation, the piston rod will be pushed and pulled back and forth by the push-pull plate (21). The piston cylinder (13) will draw water from the water tank (10) into the piston cylinder (13) through the water suction pipe (14). When the push-pull plate (21) pushes the piston rod up, the water will be squeezed out and sprayed onto the outer wall of the outer cylinder (5) through the nozzle, so that it flows down to the drill bit (4) to cool and lubricate the drill bit (4). Step 4: When a certain depth is reached and sampling is required, the second drive motor (7) stops working, the first drive motor (6) rotates in the opposite direction and drives the inner sleeve (19) to rotate in the opposite direction through the rotating shaft (16); at the same time, the tooth (34) engages with the tooth groove (35), and the tooth (34) pushes the rotating disk (38) to rotate in the opposite direction. When the inner sleeve (19) rotates in the opposite direction by 45 degrees, the rotating disk (38) rotates in the opposite direction by 45 degrees, so that any sample cup (18) is located at the second opening (17). At this time, the outer arc surface of the arc-shaped soil-pulling plate (39) abuts against the abutting block (40), and one side end of the arc-shaped soil-pulling plate (39) contacts the inner wall of the borehole. During the continuous reversal process, soil-pulling and sampling work is carried out, and the sampled soil is sent into the inner sleeve (19) through the second opening (17) and enters the corresponding sample cup (18). Step 5: After sampling, the first drive motor (6) rotates forward again, while the second drive motor (7) continues to work and the drill bit (4) continues to move down. When the inner sleeve (19) and the outer cylinder (5) rotate forward synchronously, the tooth (34) separates from the tooth groove (35), and the rotating disk (38) is stationary relative to the outer cylinder (5) and the inner cylinder. When the drill bit (4) descends to a certain depth and needs to be sampled again, the operation of step 4 is repeated.
