[0019] Step 2: Adjust the sampling angle by sliding the angle adjustment slide, and determine the precise angle of adjustment by the angle adjustment pointer indicating the angle adjustment scale;

[0020] Step 3: Install the drilling pipe at the lower end of the connecting seat by means of bolts, then hold the two handles at the rear end of the lifting and pressing cross bar, and control the sampling motor to rotate forward to drive the drilling pipe downward into the formation structure, and press the connecting clamp shaft into the square inside of the lower side of the conversion slide slot to lock it with the driving gear shaft, press the upper locking column (44) downward to lock it with the lower locking column, let the vibrator vibrate, and the drilling pipe rotate, so that the drilling pipe vibrates and rotates during the process of being pressed into the formation structure;

[0022] Step 5: After the drilling tube is completely pulled out, continue to control the sampling motor to reverse, and while the drilling tube continues to rise, the connecting clamp shaft slides into the square interior of the lower side of the conversion chute again under the action of multiple damping springs on the upper side and locks with the driving gear shaft, so that the sample inside the drilling tube can be shaken out, thereby obtaining the sample;

[0023] Step 6: Collect and number the samples taken out and finally send them for inspection.

[0024] Compared with the prior art, the present invention provides a water conservancy and environmental geological survey sampling structure and sampling method, which has the following beneficial effects:

[0025] 1. The present invention can adjust the angle between the support frame and the limit support very accurately through the cooperation of the rotating seat, the angle adjustment slide, the angle adjustment side rod, the angle adjustment scale and the pointer, ensure that the drilling angle meets the survey requirements, and improve the accuracy and reliability of the survey data.

[0026] 2. In the drilling stage of the drilling pipe, the present invention drives the pressure-lifting cross bar downward through the sampling motor, and drives the vibrator to vibrate by inserting the connecting card shaft into the lower square interior of the conversion slide slot, and drives the drilling pipe to rotate through the locking between the upper locking column and the lower locking column, so that the drilling pipe can effectively destroy the formation structure through the compound action and is more easily inserted into the formation, which greatly improves the drilling efficiency and reduces the drilling time and labor costs.

[0027] 3. In the drilling pipe lifting stage, the present invention drives the lifting and pressing cross bar upward through the sampling motor, and drives the vibrator to vibrate by sliding the connecting card shaft out of the square inside of the lower side of the conversion slide slot, and drives the drilling pipe to rotate through the separation stop between the upper locking column and the lower locking column, so that the vibration and rotation of the drilling pipe are prevented from falling off during the lifting process of the drilling pipe, thereby ensuring the success rate of sampling and the integrity of the sample.

[0028] 4. In the present invention, after the drilling pipe is completely pulled out of the formation, the connecting card shaft is inserted into the square interior of the lower side of the conversion slot again through multiple shock-absorbing springs on the upper side to drive the vibrator to vibrate, so as to shake the sample out from the lower end of the drilling pipe, thereby facilitating the removal of the sample, significantly improving the sampling efficiency, and reducing the complexity of the operation.

[0029] 5. The combined design of the active bevel gear, the driven bevel gear and the eccentric wheel inside the vibrator of the present invention can produce a stable and efficient vibration effect, thereby increasing the drilling speed of the drilling pipe. At the same time, through structures such as shock-absorbing springs and connecting slide rods, the impact of vibration on the pressure-lifting cross bar can be effectively absorbed and reduced, thereby ensuring the stability and durability of the entire structure.

[0030] 6. When the drilling pipe contacts the ground and starts drilling, the present invention realizes locking, ensuring the effective transmission of downward pressure, vibration and rotation actions, thereby improving the drilling efficiency. When the drilling pipe is pulled out, the device is unlocked in time, and only moves upward without vibration and rotation, thereby ensuring the integrity of sampling. When the drilling pipe is completely pulled out, the connecting card shaft and the driving gear shaft are locked again, and only moves upward and vibrates without rotation, thereby improving the sampling efficiency and allowing the sampling mechanism to automatically switch functions according to different stages of drilling without human intervention.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The present invention provides Figure 1-Figure 12The shown hydraulic and environmental geological survey sampling structure and sampling method include a limit support 1, and the left and right sides of the upper end of the limit support 1 are connected to a rotating seat 2, and the two rotating seats 2 are located at the front side of the upper end of the limit support 1, and the front side of the upper end of the limit support 1 is rotatably connected to a support frame 3 through two rotating seats 2, and the upper ends of the two rotating seats 2 are respectively connected to the left and right sides of the lower end of the support frame 3, and a lifting and pressing cross bar 4 is clamped inside the upper end of the support frame 3, and handles are provided on the left and right sides of the rear end of the lifting and pressing cross bar 4, and a sampling motor 5 is fixedly connected to the center of the upper end of the lifting and pressing cross bar 4, and the sampling motor 5 is electrically connected to an external power supply through a power cord, and the sampling motor 5 can realize forward and reverse rotation, and the sampling motor 5 can adopt an existing known motor, and the forward and reverse rotation of the motor is an existing known public technology, so This will not be described in detail in this technical document. The lower end of the pressure-lifting crossbar 4 is connected to a vibrator 6, and the lower end of the vibrator 6 is connected to a connecting seat 7. The lower end of the connecting seat 7 is sleeved with a drilling pipe 8 with an opening downward, and is fixedly connected by bolts, and the lower end of the drilling pipe 8 is provided with cutting teeth. In the process of sampling for hydraulic and environmental geological exploration, the stratum structure of a specified depth is drilled at the sampling point through the sampling mechanism, and the stratum structure is sent to the laboratory for testing, so as to understand the nature of the stratum structure and provide basic geological data for engineering construction. After cleaning up the upper debris of the sampling point, the sampling structure is stably placed on the upper end of the sampling point through the limiting support 1, the drilling pipe 8 is sleeved on the lower end of the connecting seat 7, and then fixed by bolts, and then the support frame 3 is rotated by the rotating seat 2 to adjust the drilling After adjusting the drilling angle, hold the two handles at the rear end of the pressure-lifting cross bar 4, and control the sampling motor 5 to rotate forward. When the sampling motor 5 rotates forward, the sampling motor 5 can drive the pressure-lifting cross bar 4 to move downward, and squeeze the vibrator 6, the connecting seat 7 and the drilling pipe 8 to move downward together, so that the drilling pipe 8 can be smoothly inserted into the formation mechanism. While the drilling pipe 8 is inserted into the formation mechanism, the sampling motor 5 can drive the vibrator 6 to vibrate, so that the vibrator 6 hits the drilling pipe 8 through vibration, and drives the connecting seat 7 and the drilling pipe 8 to rotate, so that the drilling pipe 8 can cut the formation structure through the cutting teeth at the lower end, so that the drilling pipe 8 can vibrate and rotate while being pressed down, and can be inserted into the formation mechanism more easily, thereby improving the drilling efficiency. 8 After drilling to the specified depth, the sampling motor 5 is controlled to reverse.

Since the two driven bevel gears 35 are fixedly connected to the eccentric wheel 36 on the inner side of the left end and the eccentric wheel 36 on the outer side of the right end through the driven gear shaft 40, and the two eccentric wheels 36 on the inner side are connected to the two interlocking gears 39 through the rear connecting shaft 37, and the two eccentric wheels 36 on the outer side are connected to the two interlocking gears 39 through the front connecting shaft 38, the two eccentric wheels 36 on the inner side and the two eccentric wheels 36 on the outer side can rotate oppositely inside the vibration machine 6 through the four vibration chambers 34.

[0050] Preferably, Figure 8 As shown, shaft holes and gear grooves are respectively provided inside the vibration machine 6 corresponding to the rear connecting shaft 37, the front connecting shaft 38 and the linkage gear 39, so that the rear connecting shaft 37 and the front connecting shaft 38 can rotate smoothly inside the vibration machine 6 without deviation, and bearings can be optionally provided inside the shaft holes, thereby reducing the friction between the rotating rear connecting shaft 37, the front connecting shaft 38 and the shaft holes.

[0051] Preferably, since the lower sides of the outer ends of the four eccentric wheels 36 are fixedly connected with eccentric blocks, when the eccentric blocks of the four eccentric wheels 36 rotate to the uppermost side at the same time, the centrifugal force generated by the eccentric blocks of the four eccentric wheels 36 will drive the vibrator 6 to vibrate upward, and when the eccentric blocks of the four eccentric wheels 36 rotate to the lowermost side at the same time, the centrifugal force generated by the eccentric blocks of the four eccentric wheels 36 will drive the vibrator 6 to vibrate downward, and when the eccentric blocks of the two inner eccentric wheels 36 and the eccentric blocks of the two outer eccentric wheels 36 have not rotated to the uppermost side and the lowermost side, the inner two eccentric wheels 36 and the outer two eccentric wheels 36 are not rotated to the uppermost side and the lowermost side, the centrifugal force generated by the eccentric blocks of the four eccentric wheels 36 will drive the vibrator 6 to vibrate downward. 36 rotates in opposite directions, so the centrifugal forces generated by the eccentric masses of the two inner eccentric wheels 36 and the eccentric masses of the two outer eccentric wheels 36 will cancel each other out, so that the vibrator 6 can vibrate in the up and down directions, thereby striking the connecting seat 7 and the drilling pipe 8, thereby improving the efficiency of inserting the drilling pipe 8 into the formation and improving the drilling efficiency. The vibrator 6 can slide on the two connecting plates 25 through the four connecting slide bars 26, and the elastic absorption of the multiple shock-absorbing springs 28 on the upper and lower sides reduces the impact of vibration on the pressure-lifting cross bar 4, reduces the vibration of the pressure-lifting cross bar 4, and ensures the stability of the sampling mechanism.

[0052] Preferably, the lower end of the driving gear shaft 30 is fixedly connected with a telescopic shaft 41, and the telescopic shaft 41 is clamped on the outside of the lower end of the vibrator 6 and passes through the upper end of the connecting seat 7. A locking chamber 42 is opened inside the connecting seat 7. The upper side of the locking chamber 42 is cylindrical, and the lower side of the locking chamber 42 is square. An upper pre-rotation ring 43 is rotatably connected to the upper end of the locking chamber 42, and the upper pre-rotation ring 43 is fixedly connected to the lower end of the telescopic shaft 41. A cylindrical upper locking column 44 is fixedly connected to the lower end of the upper pre-rotation ring 43. A plurality of lifting balls 45 are rollingly connected to the inner outside of the upper end of the upper pre-rotation ring 43, and the upper ends of the plurality of lifting balls 45 are attached to the The locking column 44 is provided with a locking tooth groove 49 at the lower end, and a locking tooth tooth 50 is provided at the upper end of the lower locking column 46. When the upper locking column 44 contacts the lower locking column 46, the locking tooth groove 49 can be engaged with the locking tooth tooth 50. When the drilling pipe 8 is drilled into the bottom mechanism, since a limit ring is arranged on the outside of the driving gear shaft 30 and the limit ring is located at the upper end of the vibrator 6, the driving gear shaft 30 can limit the position between the driving gear shaft 30 and the vibrator 6 through the limit ring and the telescopic shaft 41. The lifting and pressing cross bar 4 presses down the vibrator 6 through the connecting plate 25 and the multiple damping springs 28 on the lower side. The vibrator 6 drives the connecting seat 7 and the drilling pipe 8 to move downward through the driving gear shaft 30 and the telescopic shaft 41. When the drilling pipe 8 contacts the ground, the drilling pipe 8 stops moving downward. The telescopic shaft 41 slides into the inside of the connecting seat 7 under the downward pressure of the vibrator 6, and drives the upper pre-rotation ring 43 and the upper The locking column 44 slides downward inside the locking chamber 42. At this time, the upper locking column 44 is inserted into the upper end of the lower pre-rotation ring 47, so that the outer side of the lower end of the upper pre-rotation ring 43 is first in contact with the inner side of the upper end of the lower pre-rotation ring 47, and then the upper locking column 44 is in contact with the lower locking column 46, and the locking tooth grooves 49 and the locking teeth 50 on the upper and lower sides are engaged with each other, so as to lock the telescopic shaft 41 and the connecting seat 7, so that the telescopic shaft 41 can drive the connecting seat 7 to rotate through the upper locking column 44 and the lower locking column 46, and drive the drilling pipe 8 to rotate through the connecting seat 7, so as to realize the downward pressure, vibration and rotation of the drilling pipe 8 at the same time.

[0053] Preferably, during the process of the upper pre-rotation ring 43 and the lower pre-rotation ring 47 being fitted and pressed downward, the lower pre-rotation ring 47 can gradually increase the friction between itself and the upper pre-rotation ring 43 through the pre-compression spring 48, so that the upper pre-rotation ring 43 can drive the lower pre-rotation ring 47 and the connecting seat 7 to pre-rotate through the increase in friction, thereby reducing the speed difference between the upper locking column 44 and the lower locking column 46, allowing the upper locking column 44 to fit more stably with the lower locking column 46, and the locking tooth groove 49 and the locking tooth teeth 50 to engage more stably, which can not only make the telescopic shaft 41 and the connecting seat 7 more smoothly connected, but also reduce the wear between the locking tooth groove 49 and the locking tooth teeth 50.

[0054] Preferably, when the sampling motor 5 is controlled to reverse, the sampling motor 5 drives the internal threaded rotating shaft 20 to reverse, and the internal threaded rotating shaft 20 moves upward outside the pressure-lifting screw 16 through the thread, and drives the pressure-lifting cross bar 4 to move upward, and the pressure-lifting cross bar 4 pulls up the four connecting slide bars 26 through the connecting plate 25 and the multiple shock-absorbing springs 28 on the upper side and the multiple spring limiting rings 27 on the upper side, and pulls up the vibrator 6 through the four connecting slide bars 26, and the vibrator 6 then pulls up the connecting seat 7 and the drilling pipe 8 through the telescopic shaft 41. At this time, there is a large friction between the drilling pipe 8 and the formation, and the connecting clamping shaft 29 slides upward inside the conversion slide groove 31 under the pulling of the pressure-lifting cross bar 4, and slides into the cylindrical interior on the upper side of the conversion slide groove 31. Since the connecting clamping shaft 29 can rotate inside the cylindrical interior of the conversion slide groove 31, The lock between the connecting card shaft 29 and the conversion slide groove 31 is released, so that the driving gear shaft 30 stops rotating and no longer drives the four eccentric wheels 36 inside the vibrator 6 to rotate, so that the vibrator 6 stops vibrating. At the same time, the telescopic shaft 41 drives the upper pre-rotation ring 43 and the upper locking column 44 to slide upward in the locking chamber 42 under the lifting of the vibrator 6, so that the upper pre-rotation ring 43 is separated from the lower pre-rotation ring 47, and the upper locking column 44 is separated from the lower locking column 46, so that the lock between the telescopic shaft 41 and the connecting seat 7 is released, and the multiple lifting balls 45 inside the upper end of the upper pre-rotation ring 43 are rotated in the locking chamber 42, and the connecting seat 7 is lifted at the same time, so that the drilling pipe 8 is no longer vibrated and rotated during the lifting process, so as to prevent the sample from falling off from the drilling pipe 8 when the drilling pipe 8 is not pulled out from the formation structure.

[0055] Preferably, when the drilling pipe 8 is completely pulled out from the inside of the stratum structure, since the drilling pipe 8 is no longer constrained by the stratum structure, the weight of the drilling pipe 8 and the geological sample taken out cannot overcome the elastic deformation force generated when the shock-absorbing spring 28 is pulled upward. Therefore, the vibrator 6, the connecting seat 7 and the drilling pipe 8 move upward under the action of the multiple shock-absorbing springs 28 on the upper side, and the vibrator 6 drives the driving gear shaft 30 to move upward. Since the lower end of the connecting card shaft 29 is conical, and the cylindrical inner wall on the upper side of the conversion slide 31 and the square inner wall on the lower side are connected, the vibration machine 6, the connecting seat 7 and the drilling pipe 8 move upward. The connection is smooth, so the connecting card shaft 29 can smoothly slide to the square inside of the lower side of the conversion slide groove 31 during the upward movement of the driving gear shaft 30, and the connecting card shaft 29 and the conversion slide groove 31 are locked again, so that the sampling motor 5 on the lifting and pressing cross bar 4 can drive the driving gear shaft 30 to rotate again through the connecting card shaft 29, so that the vibrator 6 vibrates again, thereby shaking the sample out from the lower end of the drilling pipe 8, making it more convenient to take out the sample and improving the sampling efficiency. When the lifting and pressing cross bar 4 moves to the uppermost side, the sampling motor 5 is turned off and the geological sample is taken out.
