[0012] Preferably, a plurality of limiting holes are provided on the inner wall of the sampling rack, and the plurality of limiting holes are respectively located on both sides of the slide slot, and the type and specification of the limiting holes are consistent with those of the limiting columns.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. By placing the device on the sampling point, the person holds the handle with his hand and steps on the foot pedal with his foot. At this time, the hydraulic cylinder and the drive motor are started at the same time. The hydraulic cylinder drives the sampling tube to move up and down, and the drive motor drives the sampling tube to rotate. In the process of the sampling tube moving downward, the drill bit is used to break the hard rock layer. At the same time, the high-speed rotating external threaded drill barrel will drill into the interior of the rock layer and place the sample inside the external threaded drill barrel. At this time, the external threaded drill barrel is pulled out of the rock layer to complete the sampling of the rock and soil. At this time, the person presses the handle to drive the push column to move inside the sampling tube, and the rock and soil samples inside the external threaded drill barrel are completely ejected through the push column. The rock and soil samples themselves are not affected during the removal process, which ensures the integrity of the samples and helps to improve the accuracy of the rock and soil sample detection results.
[0015] 2. By setting a limit block, before the rock and soil sampling operation, the position of the limit block can be slid in the slide groove as required. When the limit block is moved to a specified height, the pull plate is manually released. At this time, the tension of the spring is applied to the pull plate, driving the limit column to move inside the limit block, and making one end of the limit column inserted into the limit hole at the corresponding position, so that the limit column and the limit hole are engaged, thereby fixing the position of the limit block. During the sampling operation, since the limit sleeve and the sampling tube move up and down synchronously, the protrusion slides inside the slide groove during the up and down movement of the sampling tube. When the protrusion moves to the top of the limit block, it cannot continue to move downward, thereby realizing the limitation of the sampling depth of the external threaded drill tube, realizing the demand for accurate sampling depth, and solving the problem that the existing device cannot accurately limit its sampling depth.

[0023] Among them, a slot is opened at the bottom of the sampling frame 1 for the external threaded drill barrel 13 to pass through. After holding the handle 3 by hand and stepping on the foot pedal 2 with the foot, the hydraulic cylinder 4 and the drive motor 6 are started at the same time. The hydraulic cylinder 4 drives the sampling barrel 12 to move up and down, and the drive motor 6 drives the sampling barrel 12 to rotate. In the process of the sampling barrel 12 moving downward, the drill bit 14 is used to break the hard rock formation. At the same time, the high-speed rotating external threaded drill barrel 13 will drill into the interior of the rock formation and place the sample inside the external threaded drill barrel 13. At this time, the external threaded drill barrel 13 is pulled out of the rock formation to complete the sampling of the rock and soil.
[0024] Among them, a push column 16 is slidably inserted inside the sampling tube 12, and a handle 17 is fixedly connected to the bottom end of the push column 16. A through groove 15 is opened on the side wall of the sampling tube 12, and the handle 17 is slidably engaged with the through groove 15. The push handle 17 is pressed by hand to drive the push column 16 to move inside the sampling tube 12. The rock and soil samples inside the externally threaded drill tube 13 are completely ejected through the push column 16, and the layers of the rock and soil samples themselves are not affected during the removal process, thereby ensuring the integrity of the samples.
[0025] Among them, the surface of the clamping block 7 is rotatably clamped with the limiting ring 8, and the two sides of the limiting ring 8 are fixedly connected with protrusions 9. The inner wall of the sampling frame 1 is provided with a sliding groove 10, and the sliding groove 10 is slidably clamped with the protrusion 9 to improve the stability of the sampling tube 12 during sampling.
[0026] Among them, the internal sliding card of the slide groove 10 is connected with the limit block 18, and the two ends of the limit block 18 are slidably inserted with the limit column 19, one end of the limit column 19 is fixedly connected with the pull plate 20, and the surface of the limit column 19 is movably sleeved with a spring 21, one end of the spring 21 is fixedly connected to the limit block 18, and the other end of the spring 21 is fixedly connected to the pull plate 20. The inner wall of the sampling rack 1 is provided with a plurality of limit holes 11, and the plurality of limit holes 11 are respectively located on both sides of the slide groove 10. The model specifications of the limit holes 11 and the limit column 19 are consistent. When the limit block 18 is moved to a specified height, the pull plate 20 is released manually, and the spring 21 is then The pulling force of 21 is applied to the pull plate 20, driving the limit column 19 to move inside the limit block 18, and making one end of the limit column 19 inserted into the limit hole 11 at the corresponding position, so that the limit column 19 is engaged with the limit hole 11, thereby fixing the position of the limit block 18. During the sampling operation, since the limit collar 8 and the sampling tube 12 move up and down synchronously, the protrusion 9 slides inside the slide groove 10 during the up and down movement of the sampling tube 12. When the protrusion 9 moves to the top of the limit block 18, it cannot continue to move downward, thereby limiting the sampling depth of the external threaded drill tube 13.
[0027] Working principle: when the device is in use, a person holds the handle 3 by hand and steps on the foot pedal 2 with his foot. At this time, the hydraulic cylinder 4 and the drive motor 6 are started at the same time. The hydraulic cylinder 4 drives the sampling tube 12 to move up and down, and the drive motor 6 drives the sampling tube 12 to rotate. In the process of the sampling tube 12 moving downward, the drill bit 14 is used to break the hard rock layer. At the same time, the high-speed rotating external threaded drill barrel 13 will drill into the interior of the rock layer and place the sample inside the external threaded drill barrel 13. At this time, the external threaded drill barrel 13 is pulled out of the rock layer to complete the sampling of the rock and soil. At this time, the person presses the pull handle 17 by hand to drive the push column 16 to move inside the sampling tube 12, and the rock and soil samples inside the external threaded drill barrel 13 are completely ejected through the push column 16. In the process of taking out, the rock and soil samples themselves are not affected, thereby ensuring the integrity of the samples. The limit block 18 can be slid into the position in the slide groove 10 according to the requirements before the soil sampling operation. When the limit block 18 is moved to the specified height, the pull plate 20 is manually released. At this time, the tension of the spring 21 is applied to the pull plate 20, driving the limit column 19 to move inside the limit block 18, and making one end of the limit column 19 inserted into the limit hole 11 at the corresponding position, so that the limit column 19 is engaged with the limit hole 11, thereby fixing the position of the limit block 18. During the sampling operation, since the limit collar 8 and the sampling tube 12 move up and down synchronously, the protrusion 9 slides inside the slide groove 10 during the up and down movement of the sampling tube 12. When the protrusion 9 moves to the top of the limit block 18, it cannot continue to move downward, thereby realizing the limitation of the sampling depth of the external threaded drill tube 13.
