[0020] The present invention provides a survey sampling device, which includes a sampling piece, a cutting assembly and a driving assembly. A sampling cavity is provided inside the sampling piece and is arranged to penetrate along a first direction.

When the driving member is in the unlocked state, the other end of the driving member can push the extension member out of the sampling member. As the sampling member rotates around the first direction, the extension member outside the sampling member will generate friction with the surrounding strata or rocks.

Through the above settings, the survey sampling device of the present application can ensure that the columnar rock and soil samples are separated from the rock formation, and sampling is more convenient and quick.

[0035] like Figure 1-Figure 8 As shown, this embodiment provides a survey sampling device, which includes a sampling member 1, a cutting assembly 2 and a driving assembly 3. The sampling member 1 is provided with a sampling cavity 11 which is arranged through along a first direction, the cutting assembly 2 includes a cutting member 21 and a protruding member 22, the sampling cavity 11 is provided with a receiving groove 111 along its own circumference, the cutting member 21 is arranged in the receiving groove 111, the protruding member 22 is connected to the sampling member 1, and the driving assembly 3 includes a driving member 31, the driving member 31 is slidably connected to the sampling member 1, when the driving member 31 is in a locked state, one end of the driving member 31 can abut against the protruding member 22 to limit the cutting member 21 in the sampling member 1, when the driving member 31 is in an unlocked state, the other end of the driving member 31 can push the protruding member 22 out of the sampling member 1, the protruding member 22 can pull the cutting member 21 out of the sampling cavity 11, and cut the sample in the sampling cavity 11 along a second direction, and the second direction is arranged at an angle to the first direction.

[0036] In this embodiment, a sampling cavity 11 is provided inside the sampling member 1 and is arranged to penetrate along a first direction. The sampling member 1 rotates around the first direction on the formation or rock, so that the sampling cavity 11 can collect the corresponding sample, and the integrity and original state of the sample are maintained. The cutting assembly 2 includes a cutting member 21 and a protruding member 22. A receiving groove 111 is provided inside the sampling cavity 11 along its own circumference. The cutting member 21 is arranged in the receiving groove 111 to avoid interfering with the normal drilling process. The driving assembly 3 includes a driving member 31, which is slidably connected to the sampling member 1, so that the driving member 31 slides relative to the sampling member 1, thereby switching the unlocking and locking states of the driving member 31. When the driving member 31 is in the locked state, one end of the driving member 31 can abut against the protruding member 22 to limit the cutting member 21 in the sampling member 1, ensuring that the cutting member 21 can stably stay in the sampling member 1 when sampling is not required, and the cutting action will not be accidentally triggered, thereby protecting the drilling equipment and the obtained samples. When the driving member 31 is in the unlocked state, the other end of the driving member 31 can push the extension member 22 out of the sampling member 1. As the sampling member 1 rotates in the first direction, the extension member 22 outside the sampling member 1 will generate friction with the surrounding strata or rocks. Since the extension member 22 is connected to the sampling member 1, the extension member 22 will pull the cutting member 21 out of the sampling cavity 11 under the action of friction and cut the sample in the sampling cavity 11 along the second direction, thereby effectively solving the problem that the columnar rock and soil samples are not easy to separate from the rock formation. Through the above settings, the survey sampling device of this embodiment can ensure that the columnar rock and soil samples are separated from the rock formation, and sampling is more convenient and quick.

[0037] It is understandable that in this embodiment, the first direction is the vertical direction and the second direction is the horizontal direction, so as to facilitate drilling sampling. In other embodiments, the first direction and the second direction can be adjusted according to specific drilling sampling, and no further limitation is made here.

[0038] Specifically, in this embodiment, the sampling member 1 is a through-type cylindrical structure to ensure that the sampling member 1 can obtain a columnar rock and soil sample during drilling sampling. In other embodiments, the sampling member 1 is an octagonal column, that is, the specific structure of the sampling member 1 is not limited, as long as it can achieve the above-mentioned functions.

[0039] Specifically, Figure 1 and Figure 2 As shown, a cutting tooth 12 is provided at one end of the sampling member 1 along the first direction, so that the survey sampling device can better penetrate the stratum or rock, especially when encountering a relatively hard or difficult-to-penetrate medium, the cutting tooth 12 can provide additional cutting force to help the sampling member 1 smoothly enter and collect samples. In detail, the cutting tooth 12 includes a plurality of staggered tooth portions, and the plurality of tooth portions are arranged at intervals along the circumference of the sampling member 1 to improve the sampling efficiency.

[0040] Specifically, Figure 1-Figure 4 As shown, a connection hole 13 is provided on the sampling piece 1, and the receiving groove 111 is connected to the outside through the connection hole 13. The cutting piece 21 is arranged along the extension direction of the receiving groove 111, so that when the sampling piece 1 drills the sample, the cutting piece 21 can be sleeved on the outer wall of the sample and perform cutting operations. One end of the cutting piece 21 is fixedly connected to the sampling piece 1, and the other end passes through the connection hole 13 and is connected to the protruding piece 22. When the sampling piece 1 rotates in a first direction, the protruding piece 22 located outside the sampling piece 1 will generate friction with the surrounding strata or rocks. Since the protruding piece 22 is connected to the sampling piece 1, the protruding piece 22 will pull the cutting piece 21 out of the sampling cavity 11 under the action of friction, which not only ensures that the cutting piece 21 can be smoothly extended for cutting, but also enables the force generated during the cutting process to be effectively transmitted and dispersed. As shown in FIG. Figure 1-Figure 4 As shown, when there is no need to cut the sample, the protruding piece 22 can abut against the inner wall of the connecting hole 13. Since the length of the protruding piece 22 is greater than the height of the accommodating groove 111 and less than the height of the connecting hole 13, the protruding piece 22 is vertically received inside the connecting hole 13, so that the protruding piece 22 will not fall into the sampling cavity 11 due to external force.

[0041] It should be noted that the cutting piece 21 includes structures such as alloy steel, tungsten steel and metal ceramics, so as to facilitate the extraction of the cutting piece 21 and the cutting of the columnar rock mass. The specific structure of the cutting piece 21 will not be described in detail herein.

[0042] Specifically, Figure 1-Figure 5As shown, the surveying and sampling device also includes a locking assembly 4, which includes a locking piece 41. The driving piece 31 is provided with a first locking hole 311. When the locking piece 41 is inserted into the first locking hole 311, the driving piece 31 is located in the first orientation. At this time, the position of the driving piece 31 relative to the sampling piece 1 is fixed, which is equivalent to locking the driving piece 31 on the sampling piece 1, so that one end of the driving piece 31 can abut the protruding piece 22 against the sampling piece 1, and the protruding piece 22 is located in the connecting hole 13 at the lower limit of the abutting action of the driving piece 31, so that the protruding piece 22 will not fall out accidentally and affect the normal drilling sampling operation.

[0043] Specifically, Figure 4 and Figure 5 As shown, the locking assembly 4 also includes an elastic member 42, a limiting groove 14 is provided in the sampling member 1, the extension direction of the limiting groove 14 is perpendicular to the sliding direction of the driving member 31, the locking member 41 is slidably arranged in the limiting groove 14, the two ends of the elastic member 42 are respectively abutted against the locking member 41 and the bottom of the limiting groove 14, and the locking member 41 extends into the first lock hole 311 under the support of the elastic member 42, realizing the automatic reset and buffering and shock absorbing functions of the locking member 41, and also ensuring the reliability and stability of the locking operation. Among them, the elastic member 42 includes a compression spring or a tension spring, which is not limited too much here.

[0044] Specifically, Figure 1-Figure 5 As shown, the locking assembly 4 also includes an unlocking driver 43, the output end of which is connected to the locking member 41, and can drive the locking member 41 to be pulled out from the first lock hole 311. When the driving member 31 needs to be unlocked, the unlocking driver 43 can drive the locking member 41 to be pulled out from the first lock hole 311, without the need for manual operation, thereby improving the efficiency and reliability of unlocking.

[0045] More specifically, in this embodiment, the unlocking driver 43 includes an air pump and an air inlet pipe. The air outlet of the air pump is connected to one end of the limiting groove 14 near the locking member 41 through the air inlet pipe. When the gas pumped out by the air pump enters the limiting groove 14 through the air inlet pipe, the locking member 41 moves toward the bottom of the limiting groove 14 under the action of the gas pressure and compresses the elastic member 42 until the locking member 41 is withdrawn from the first locking hole 311 to unlock the driving member 31, so that the driving member 31 can slide relative to the sampling member 1 again. When the other end of the driving member 31 pushes the extension member 22 out of the sampling member 1, in order to prevent the driving member 31 from detaching from the sampling member 1, a second locking hole is provided on one end of the driving member 31. The locking member 41 can extend into the second locking hole under the support of the elastic member 42. At this time, the driving member 31 is in the second direction, and the second direction is set at an angle to the first direction.

[0046] More specifically, in other embodiments, the unlocking driver 43 includes an electric push rod, the output end of which is connected to the locking member 41, and can pull the locking member 41 out of the first lock hole 311. It can be understood that the specific structure of the unlocking driver 43 is not limited, as long as the above-mentioned functions can be achieved.

[0047] Specifically, the sampling member 1 is provided with an arc-shaped chute 15, and the driving member 31 is slidably disposed in the arc-shaped chute 15. One end of the arc-shaped chute 15 is connected to the outside through the connecting hole 13, so that one end of the driving member 31 can extend from the arc-shaped chute 15 and abut the extending member 22 against the inner wall of the connecting hole 13, thereby realizing the limiting effect of the extending member 22. In addition, when the driving member 31 slides in the arc-shaped chute 15, the other end of the driving member 31 can extend from one end of the arc-shaped chute 15 and abut the extending member 22, thereby pushing the extending member 22 out of the connecting hole 13 to the outside of the sampling member 1. When the sampling member 1 rotates around the first direction, the extending member 22 will generate friction with the surrounding strata or rocks, and then the cutting member 21 will be pulled out of the sampling cavity 11 under the action of the friction force, ensuring that the cutting member 21 can be smoothly drawn out and cut the sample.

[0048] Specifically, the driving component 3 also includes a push-pull driver, the output end of which is connected to the driving member 31, which can drive the driving member 31 to slide in the arc-shaped slide groove 15, thereby facilitating the state switching of the driving member 31 without manual adjustment, thereby improving work efficiency.

[0049] More specifically, if Figure 1-Figure 6 As shown, in this embodiment, the push driver includes an air pump, an air inlet passage 16 is provided in the sampling member 1, and the air outlet end of the air pump is connected to the arc-shaped slide groove 15 through the air inlet passage 16. The driving member 31 is sealed and slidably arranged in the arc-shaped slide groove 15, thereby ensuring the relative sealing of the arc-shaped slide groove 15, so that the driving member 31 can slide more smoothly under the driving action of air pressure, and the driving member 31 is provided with a plurality of driving grooves 312 at intervals along its own extension direction. The gas pumped out by the air pump pushes the driving grooves 312 through the air inlet passage 16, and can drive the driving member 31 to slide in the arc-shaped slide groove 15. Moreover, the arc-shaped slide groove 15 is provided with an expanded end near the other end of the driving member 31, so that the sealing effect between the driving member 31 and the arc-shaped slide groove 15 is released when the driving member 31 slides to the expanded end, so as to ensure that the other end of the driving member 31 can push the extension member 22 out more smoothly.

[0050] It should be noted that the air pump for the unlocking drive 43 and the air pump for the pushing drive can be the same air pump to save operating costs. The air intake passage 16 is connected to the air intake pipe. The gas pumped out by the air pump can reach the limit groove 14 and the arc-shaped slide groove 15 respectively through the air intake pipe and the air intake passage 16. Among them, the gas reaches the limit groove 14 before the arc-shaped slide groove 15 to ensure that the driving member 31 can be unlocked first, and then slide to push the protruding member 22.

[0051] In other embodiments, the push-pull drive includes a motor and a gear. The output shaft of the motor is connected to the gear, which can drive the gear to rotate around its own axis. The driving member 31 is provided with a toothed portion meshing with the gear, and the driving member 31 is driven to slide in the arc-shaped groove 15 through the rotation of the gear. That is, the specific structure of the push-pull drive is not limited, as long as the above-mentioned functional effects can be achieved.

[0052] Specifically, the driving member 31 extends in an arc shape, the central angle of the driving member 31 is greater than 180 degrees, and the cross-sectional structure of the arc-shaped slide groove 15 along the first direction is roughly three-quarters of a ring, so that the driving member 31 can slide in the arc-shaped slide groove 15 relative to the sampling member 1, thereby achieving the limiting and pushing effect on the protruding member 22, so as to improve the convenience of operation.

[0053] The specific working process of this device is described below:

[0054] After the sampling member 1 drills toward the rock or stratum to a predetermined depth, the air pump is turned on. When the gas pumped out by the air pump enters the limiting groove 14 through the air inlet pipe, the locking member 41 moves toward the bottom of the limiting groove 14 under the action of the gas pressure and compresses the elastic member 42 until the locking member 41 is withdrawn from the first lock hole 311 to unlock the driving member 31, so that the driving member 31 can slide relative to the sampling member 1. After the driving member 31 is unlocked, the gas of the air pump will enter the arcuate slide groove 15 through the air inlet passage 16. Since the driving member 31 is provided with a plurality of driving grooves 312 at intervals along its own extension direction, the gas in the arcuate slide groove When the sampling member 1 is in a relatively sealed state, the driving groove 312 will be pushed against, thereby driving the driving member 31 to slide in the arc-shaped slide groove 15 until the other end of the driving member 31 can push the protruding member 22 out of the sampling member 1. As the sampling member 1 rotates around the first direction, the protruding member 22 outside the sampling member 1 will generate friction with the surrounding strata or rocks. Since the protruding member 22 is connected to the sampling member 1, the protruding member 22 will pull the cutting member 21 out of the sampling cavity 11 under the action of the friction force, and cut the sample in the sampling cavity 11 along the second direction, thereby effectively solving the problem that the columnar rock and soil sample is not easy to separate from the rock formation.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
