[0002] Currently, most sampling devices used in engineering geological exploration employ fixed-angle drilling, which suffers from limitations such as a single sampling angle and difficulty in adapting to complex geological conditions.

[0015] Compared with the prior art, the present invention provides a rapid sampling device for engineering geological exploration, which has the following beneficial effects: 1. This invention uses an angle-adjusting component to precisely adjust and fix the sampling angle of the sampling tube. This not only enables multiple precise samplings under the same conditions at the same sampling angle, but also allows for diverse precise samplings at different sampling angles, thereby meeting the precise sampling requirements under different geological conditions.

[0016] 2. The present invention uses an anti-jamming component to drive the drive cylinder and sampling cylinder to rotate and cut into the ground. When the resistance of the sampling cylinder increases, the anti-jamming component can buffer the increased resistance, avoid the drive motor from being subjected to large instantaneous torque, avoid causing excessive load on the drive motor, and thus ensure the stable operation of the drive motor.

[0017] 3. This invention prevents the drive motor from completely jamming and losing driving force by using an anti-jamming component. When the sampling cylinder jams, the drive motor will drive the drive push block to rotate inside the drive cylinder and drive the anti-jamming component to generate a high-frequency impact on the soil layer at the lower end of the sampling cylinder. The crushing impact pin will strike and crush the hard soil layer to reduce sampling resistance, help the sampling cylinder to get out of trouble and get a sample smoothly, so that the sampling device is not easy to jam and is easy to get out of trouble.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides, for example Figures 1-11The diagram illustrates a rapid sampling device for engineering geological exploration, comprising a positioning base 1. Two longitudinal rotating seats 2 are symmetrically arranged on the upper end of the positioning base 1, and a sampling cylinder 3 is disposed between the two longitudinal rotating seats 2, penetrating inside the positioning base 1. The lower end of the sampling cylinder 3 is provided with multiple cutting teeth, and a drive cylinder 4 is connected to the upper end of the sampling cylinder 3. A drive motor 5 is connected to the upper end of the drive cylinder 4. An angle adjustment component is provided between the longitudinal rotating seats 2 and the sampling cylinder 3, allowing adjustment and limitation of the sampling angle of the sampling cylinder 3. An anti-jamming component is connected between the drive cylinder 4 and the drive motor 5. The drive motor 5 can drive the sampling cylinder 3 and the drive cylinder 4 through the anti-jamming component, and can buffer and release the sampling cylinder 3 from jamming. During the engineering geological exploration, the sampling cylinder 3 is drilled into the ground to collect samples. At this time, the drive motor 5 is electrically connected to the external power supply through the wiring harness. After the drive motor 5 is started, the drive motor 5 drives the drive cylinder 4 to rotate through the output shaft and the anti-jamming component, and drives the sampling cylinder 3 to rotate through the drive cylinder 4. The lower end of the sampling cylinder 3 cuts into the ground through multiple cutting teeth and rapid rotation, and the sample is introduced into the sampling cylinder 3 for extraction.

[0032] The sampling tube 3 can be positioned at the bottom by the positioning base 1, and the drilling angle can be adjusted and fixed by the angle adjustment component between the positioning base 1 and the sampling tube 3, so that the sampling tube 3 can be accurately and quickly fixed at the angle where sampling is required, ensuring the accuracy and diversity of sampling.

[0033] In addition, the drive motor 5 can be connected to the drive cylinder 4 through the anti-jamming component, and can buffer the resistance when the sampling cylinder 3 is subjected to resistance, so as to avoid the resistance causing a large instantaneous load on the drive motor 5, reduce the heat generation of the drive motor 5, and ensure the stable operation of the drive motor 5. When the sampling cylinder 3 jams, the drive motor 5 can avoid jamming through the anti-jamming component. At the same time, the drive anti-jamming component generates a downward high-frequency impact to break the sample at the lower end of the sampling cylinder 3, reduce the resistance on the sampling cylinder 3, and make the sampling cylinder 3 rotate again, ensuring the smooth sampling of the sampling cylinder 3.

[0034] like Figures 1-3As shown, the angle adjustment assembly includes a longitudinal angle adjustment frame 6. The longitudinal angle adjustment frame 6 is rotatably connected between two longitudinal rotating seats 2. A first rotating shaft is provided between each of the two longitudinal rotating seats 2 and the longitudinal angle adjustment frame 6, and the longitudinal angle adjustment frame 6 can be fixed by the first rotating shaft and bolts. A transverse angle adjustment cylinder 7 is rotatably connected to the middle of the interior of the longitudinal angle adjustment frame 6, and the rotation axis of the transverse angle adjustment cylinder 7 is perpendicular to the rotation axis of the longitudinal angle adjustment frame 6. Second rotating shafts are provided at both ends of the transverse angle adjustment cylinder 7 where it connects to the longitudinal angle adjustment frame 6, and the transverse angle adjustment cylinder 7 can be fixed by the second rotating shaft and bolts. Two limiting slide rods 8 are symmetrically connected to the upper outer surface of the transverse angle adjustment cylinder 7, and the two limiting slide rods 8 are sleeved with… The limiting slide 9 is connected to the outer side of the lower end of the drive motor 5. Both limiting slides 9 are connected to cutting handles 10 perpendicular to the limiting slide rods 8. During the process of adjusting and fixing the sampling angle of the sampling tube 3, the sampling tube 3 is inserted into the transverse angle adjusting tube 7, and the two limiting slide rods 8 are inserted into the limiting slides 9 at both ends of the drive motor 5 to position the sampling tube 3 inside the transverse angle adjusting tube 7. At this time, the longitudinal angle adjusting frame 6 is rotated according to the longitudinal angle of sampling. The longitudinal angle adjusting frame 6 rotates longitudinally between the two longitudinal rotating seats 2 through the first rotating shaft, and the longitudinal sampling angle is precisely adjusted by the angle scale on the outer wall of the longitudinal rotating seat 2 and the indicator scale on the outer wall of the first rotating shaft.

[0035] Similarly, the horizontal angle adjusting cylinder 7 is rotated according to the horizontal angle of the sampling, and the horizontal sampling angle is precisely adjusted by the scale on the outer wall of the vertical angle adjusting frame 6 and the indicator scale on the outer wall of the second rotating shaft. Finally, the vertical and horizontal sampling angles are fixed by bolts, thereby completing the adjustment and fixing of the sampling angle of the sampling cylinder 3. This allows the sampling cylinder 3 to perform multiple precise samplings under the same conditions at the same sampling angle, and also to perform diverse precise samplings at different sampling angles. Finally, the drive motor 5 is started, and the sampling cylinder 3 and the drive motor 5 are pressed down by the cutting handles 10 on both sides, so that the sampling cylinder 3 cuts downward into the ground.

[0036] like Figures 4-7As shown, the anti-jamming assembly includes a drive cavity 11. The drive cylinder 4 has a drive cavity 11 inside, and a drive rotating seat 12 is rotatably connected to the upper end of the drive cavity 11. The upper end of the drive rotating seat 12 extends to the outside of the drive cylinder 4 and is connected to the drive motor 5 via an output shaft. A limiting support column 13, which fits against the inner wall of the lower end of the drive cavity 11, is connected to the center of the lower end of the drive rotating seat 12. Two drive push blocks 14, rotatably connected inside the drive cavity 11, are symmetrically connected at the connection between the drive rotating seat 12 and the limiting support column 13. The intersection of one end of the two drive push blocks 14 in the rotation direction and the lower end is arranged in an arc shape. Multiple rotating pairs are formed on the inner wall of the cylindrical drive cavity 11. The system includes multiple connecting chutes 15, each externally connected to an arc-shaped compression chute 16. An arc-shaped exhaust pipe 17, located on the same arc line, is connected to the center of the inner wall of the end of the compression chute 16 furthest from the connecting chutes 15. An arc-shaped outer sealing pipe 18, also located on the same arc line, is slidably connected to the inner wall of the side of the compression chute 16 furthest from the exhaust pipe 17. The outer sealing pipe 18 is located outside the exhaust pipe 17, and its end near the exhaust pipe 17 is always inserted into the inner wall of the compression chute 16 furthest from the connecting chutes 15. A rubber sealing ring is provided between the outer sealing pipe 18 and the compression chute 16. The center of the inner wall of the end of the outer sealing pipe 18 furthest from the exhaust pipe 17 is connected to an arc-shaped exhaust pipe 17 located on the same arc line. The inner sealing tube 19 is always sleeved on the outside of the exhaust pipe 17, and a rubber sealing ring is provided between the inner sealing tube 19 and the exhaust pipe 17. A drive spring 20 located inside the outer sealing tube 18 is sleeved on the outside of the exhaust pipe 17 and the inner sealing tube 19. Multiple first exhaust grooves 21 are opened at the connection between the inner sealing tube 19 and the outer sealing tube 18. Multiple second exhaust grooves 22 are opened on the arc-shaped outer wall of the exhaust pipe 17 near the outer sealing tube 18. A limit connecting seat 23 is connected to the side of the outer sealing tube 18 near the connecting slide 15 and away from the exhaust pipe 17. The limit connecting seat 23 is completely located inside the connecting slide 15 and is slidably connected to the connecting slide 15. Inside the drive chamber 11, the end of the limiting connecting seat 23 away from the outer sealing tube 18 is rotatably connected to a drive push rod 24 that is attached to one end of the drive push block 14 in the direction of rotation. The lower end of the drive push rod 24 is provided with a release groove 25 that is inclinedly opened on the inner wall of the lower end of the connecting slide groove 15 near the exhaust pipe 17. During the process of the drive motor 5 driving the sampling cylinder 3 to rotate at high speed, the drive motor 5 drives the drive rotating seat 12 and the limiting support column 13 to rotate inside the drive chamber 11 through the output shaft, and drives the two drive push blocks 14 at the connection between the drive rotating seat 12 and the limiting support column 13 to rotate inside the drive chamber 11, so that the drive motor 5 drives the drive cylinder 4 to rotate through the drive push blocks 14.

[0037] At this time, since the outer sealing tube 18 is slidably connected inside the compression groove 16 and sealed with the end of the compression groove 16 near the exhaust pipe 17 by a rubber sealing ring, and the inner sealing tube 19 is sleeved on the outside of the exhaust pipe 17 and sealed by a rubber sealing ring, the compression groove 16 and the outer sealing tube 18 can form a closed space, i.e., a compression cavity, when the first exhaust groove 21 and the second exhaust groove 22 are not connected.

[0038] Furthermore, when the drive push block 14 rotates to fit against the drive push rod 24, the drive push block 14 can drive the limiting connecting seat 23 to slide together inside the connecting groove 15 through the drive push rod 24, and drive the outer sealing tube 18 to slide towards the exhaust pipe 17 side inside the compression groove 16, compressing the space of the compression cavity and the drive spring 20, increasing the air pressure inside the compression cavity formed by the compression groove 16 and the outer sealing tube 18. At the same time, the compressed drive spring 20 increases the elastic force of the outer sealing tube 18 and the drive cylinder 4. Since the drive spring 20 is located between the inner wall of the compression groove 16 and the inner wall of the outer sealing tube 18, the drive spring 20 can push the drive cylinder 4 through the compression groove 16 and rebound the outer sealing tube 18, so that the outer sealing tube 18 can drive the drive cylinder 4 through the air pressure thrust in the compression cavity and the elastic force of the drive spring 20, so that the drive motor 5 can drive the drive cylinder 4 through the drive push block 14 and the outer sealing tube 18.

[0039] Since the outer sealing tube 18 can be limited by the sliding of the limiting connecting seat 23 inside the connecting groove 15, the outer sealing tube 18 can only slide along the common arc with the compression groove 16, and drive the inner sealing tube 19 to slide outside the exhaust pipe 17, so as to avoid the compression groove 16 and the outer sealing tube 18 and the exhaust pipe 17 and the inner sealing tube 19 getting stuck, ensuring that the outer sealing tube 18 can slide smoothly inside the compression groove 16 and that the inner sealing tube 19 can slide smoothly outside the exhaust pipe 17.

[0040] Furthermore, when the drive push block 14 drives the outer sealing tube 18 to slide inside the compression groove 16 through the limit connecting seat 23 and the drive push rod 24, and the first exhaust groove 21 and the second exhaust groove 22 are not connected, the outer sealing tube 18 drives the drive cylinder 4 to rotate through the air pressure thrust in the compression cavity and the elastic force of the drive spring 20, and drives the sampling cylinder 3 to rotate through the drive cylinder 4. When the resistance received by the sampling cylinder 3 is balanced with the air pressure thrust in the compression cavity and the elastic force of the drive spring 20, the outer sealing tube 18 stops sliding inside the compression groove 16, allowing the drive push block 14 to drive the sampling cylinder 3 and the drive cylinder 4 to rotate at the same speed through the air pressure thrust in the compression cavity and the elastic force of the drive spring 20, so that the lower end of the sampling cylinder 3 can smoothly and steadily cut into the ground for sampling through the cutting teeth.

[0041] Furthermore, when the first exhaust groove 21 and the second exhaust groove 22 do not slide into communication, the drive push rod 24 does not slide out of the inclined groove 25.

[0042] like Figure 5 , Figure 10 and Figure 11 As shown, the lower ends of multiple exhaust pipes 17 are connected to telescopic sliding holes 32 on the side away from the outer sealing pipe 18, and the lower ends of multiple telescopic sliding holes 32 are axially inserted into the inner wall of the sampling cylinder 3. Impact sliding rods 33 are slidably connected to the lower ends of multiple telescopic sliding holes 32, and rubber sealing rings are provided between the impact sliding rods 33 and their top ends. The lower ends of multiple telescopic sliding holes 32 are connected to first spring holes 34, and the lower ends of multiple first spring holes 34 are connected to annular grooves 35. The lower ends of annular grooves 35 are connected to multiple second spring holes 36 opened inside the cutting teeth. A first spring retaining ring 37 located inside the first spring hole 34 is connected to the lower outer side of the impact sliding rod 33, and a first return spring 38 located inside the first spring hole 34 is provided at the lower end of the first spring retaining ring 37. An annular impact ring 39 is slidably connected inside the annular groove 35, and the lower end of the impact ring 39... Multiple crushing impact pins 40 are connected through the second spring hole 36. Each of the multiple crushing impact pins 40 is connected to a second spring retaining ring 41 located inside the second spring hole 36. The lower end of each of the multiple second spring retaining rings 41 is provided with a second return spring 42 located inside the second spring hole 36. The upper side of the multiple telescopic sliding holes 32 is connected to an exhaust hole 43 opened on the outer wall of the sampling cylinder 3. The multiple exhaust holes 43 are located below the top of the impact sliding rod 33. During the sampling process of the sampling cylinder 3, when the resistance of the sampling cylinder 3 increases, the drive push block 14 will drive the outer sealing tube 18 to slide again inside the compression groove 16 towards the exhaust pipe 17 through the limit connecting seat 23 and the drive push rod 24. The outer sealing tube 18 will then squeeze the compression cavity and the drive spring 20 again, increasing the air pressure in the compression cavity and the elastic force of the drive spring 20.

[0043] At this time, when the first exhaust groove 21 has not slid to the position where it connects with the second exhaust groove 22, the outer sealing tube 18 can once again balance the increased resistance of the sampling cylinder 3 by the increased air pressure thrust and the elastic force of the drive spring 20, thereby driving the sampling cylinder 3 and the drive cylinder 4 to rotate at the same speed again.

[0044] During this process, since the drive push block 14 is elastically connected to the drive cylinder 4 through the compression cavity and the drive spring 20 and drives the drive cylinder 4, the compression cavity and the drive spring 20 can buffer the increased resistance of the sampling cylinder 3, so that the increased resistance is smoothly transmitted to the drive push block 14, avoiding the drive push block 14 from bearing a large reverse torque, thereby avoiding the drive motor 5 from bearing a large instantaneous load, reducing the heat generation of the drive motor 5, and ensuring the stable operation of the drive motor 5.

[0045] Furthermore, when the sampling cylinder 3 is jammed, the drive push block 14 will drive the outer sealing tube 18 to slide towards the exhaust pipe 17 inside the compression groove 16 through the limiting connecting seat 23 and the drive push rod 24, and drive the first exhaust groove 21 to slide to communicate with the second exhaust groove 22. At this time, the high pressure gas inside the compressed cavity can be introduced into the exhaust pipe 17 through the first exhaust groove 21 and the second exhaust groove 22, and then into the telescopic sliding hole 32 through the exhaust pipe 17. At the same time, the drive push rod 24 slides to the position of disengaging from the inclined groove 25, and rotates downward along the inclined inner wall of the lower end of the disengaging inclined groove 25 and the arc surface where the end of the drive push block 14 in the rotation direction intersects with the lower end inside the limiting connecting seat 23, until the drive push rod 24 completely slides to the lower end of the drive push block 14, so that the drive push block 14 disengages from the drive push rod 24 that has rotated into the disengaging inclined groove 25, and continues to rotate inside the drive cavity 11 until it is in contact with the next drive push rod 24 and pushes the next drive push rod 24.

[0046] Furthermore, when the drive push block 14 disengages from the previous drive push rod 24 and engages with the next drive push rod 24, the drive push block 14 can drive the drive cylinder 4 again through the next drive push rod 24. This not only prevents the drive motor 5 from being completely jammed inside the drive cavity 11, but also ensures that the drive motor 5 always maintains driving force on the drive cylinder 4. Moreover, as long as the sampling cylinder 3 does not overcome the jamming resistance, the drive push block 14 will continue to repeat the above steps of disengaging from the drive push rod 24 and engaging with the next drive push rod 24.

[0047] Furthermore, when the high-pressure gas inside the compressed cavity is introduced into the telescopic sliding hole 32 through the exhaust pipe 17, the high-pressure gas will push the impact sliding rod 33 inside the telescopic sliding hole 32 to slide downward quickly, and overcome the elastic force of the first return spring 38 to strike the upper end of the impact ring 39. Under the impact of the impact sliding rod 33, the impact ring 39 slides downward in the annular sliding groove 35, and drives the breaking impact pin 40 to overcome the elastic force of the second return spring 42 and quickly pop out from the lower end of the cutting tooth, thereby rapidly striking the soil layer at the lower end of the cutting tooth to break the hard soil layer, reduce the cutting resistance of the sampling cylinder 3, and enable the sampling cylinder 3 to overcome the cutting resistance and rotate again, so as to successfully sample. This can improve the sampling efficiency and reduce the risk of the sampling cylinder 3 getting stuck.

[0048] Each disengagement and engagement between the drive push block 14 and the multiple drive push rods 24 causes the outer sealing tube 18 to compress the air inside the compression cavity. The compressed air is then introduced into the exhaust pipe 17 and the telescopic sliding hole 32 through the first exhaust groove 21 and the second exhaust groove 22. This allows the multiple impact sliding rods 33 to strike the impact ring 39 in turn and at a high frequency. It also causes the multiple breaking impact pins 40 to pop out from the lower end of the cutting teeth in turn and at a high frequency to quickly strike the soil layer, thereby continuously and at a high frequency breaking the soil layer so that the sampling cylinder 3 can quickly get out of trouble and start rotating again.

[0049] Furthermore, when the upper end of the impact slide bar 33 slides to the position of the exhaust port 43, the high-pressure gas inside the telescopic slide hole 32 can be discharged and depressurized through the exhaust port 43, allowing the impact slide bar 33 to rebound to its original position under the action of the first spring retaining ring 37 and the first return spring 38 in preparation for the next gas impact. The impact ring 39 and the breaking impact pin 40 can return to their original positions under the action of the second spring retaining ring 41 and the second return spring 42 in preparation for the next impact of the impact slide bar 33. At the same time, the outer sealing tube 18 returns to its original position under the action of the drive spring 20 in preparation for the next contact and push of the drive push block 14.

[0050] like Figures 6-9 As shown, an external air guide hole 26 is provided on the outer wall of the end of the outer sealing pipe 18 away from the exhaust pipe 17, and an inner air guide hole 27 communicating with the external air guide hole 26 is provided on the inner wall of the end of the outer sealing pipe 18 away from the exhaust pipe 17. A spring plate 28 is provided inside the external air guide hole 26, and a sealing plate 29 is provided inside the inner air guide hole 27. A connecting slide rod 31 with an air guide groove on its outer wall is connected between the spring plate 28 and the sealing plate 29. A sealing spring 30 is sleeved on the outside of the connecting slide rod 31, located at the end of the spring plate 28 near the sealing plate 29, and the sealing spring 30 is located inside the external air guide hole 26. When the outer sealing pipe 18 returns to its original position... During the process, since the gas inside the compressed cavity has been discharged from the exhaust port 43, and the volume of the compressed cavity will gradually increase as the outer sealing tube 18 returns to its original position, the compressed cavity will generate negative pressure. This negative pressure will overcome the elasticity of the sealing spring 30 and draw the sealing plate 29 from inside the inner air guide hole 27 into the compressed cavity. This allows the outer air guide hole 26 and the inner air guide hole 27 to be connected through the air guide groove opened on the outer wall of the connecting slide rod 31. This allows the compressed cavity to draw in air through the outer air guide hole 26, the inner air guide hole 27, and the air guide groove opened on the outer wall of the connecting slide rod 31, ensuring that the outer sealing tube 18 can return to its original position smoothly and quickly.

[0051] The sealing plate 29 can be tightly fitted inside the inner air guide hole 27 to seal the cavity under the action of the high-pressure gas inside when the compressed cavity is squeezed, and under the action of the sealing spring 30.
