[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] Embodiment 1:

[0033] like Figure 1-3 As shown, a geological detection sampling device includes a telescopic rod 1 and a hollow disk 2 arranged outside the telescopic rod 1.

[0034] A sampling assembly 3 is arranged inside the hollow disk 2, and the sampling assembly 3 includes a sampling tube 7 and a limiting groove 8 opened on the outer wall of the sampling tube 7. The sampling tube 7 is limited by the limiting groove 8 and cooperates with a limiting column 6. The limiting column 6 is fixedly connected to the inner wall of the hollow disk 2. One end of the sampling tube 7 and the inner wall are respectively fixedly connected with a plurality of radially arranged drilling plates 4 and separation plates 5.

[0035] When the sampling tube 7 is pushed outward, the drilling plate 4 at its end can be used to drill into the soil more easily. During the movement of the sampling tube 7, with the cooperation of the limiting column 6 and the limiting groove 8, the sampling tube 7 first moves horizontally so that the soil sample can enter the interior of the sampling tube 7. After the sampling tube 7 moves a certain distance, the limiting column 6 and the limiting groove 8 drive the sampling tube 7 to rotate, so that relative movement occurs between the separation plate 5 and the soil, thereby separating the soil and ensuring effective sampling.

[0036] The device is provided with a separation plate 5, a limiting column 6 and a limiting groove 8. With the cooperation of the limiting column 6 and the limiting groove 8, when the sampling tube 7 is pushed, the sampling tube 7 will first move horizontally along the inner wall of the hollow disk 2 and then rotate, so that after the soil enters the sampling tube 7, the separation plate 5 and the soil can move relative to each other by rotation, thereby separating the soil, ensuring effective sampling, and improving the reliability of the device.

[0037] like Figure 3-5 As shown, the outer wall of the sampling tube 7 away from the drilling plate 4 is provided with an annular groove 16, the inner wall of the annular groove 16 is movably fitted with an L-shaped rod 10, the inner wall of the sampling tube 7 is slidably fitted with a push plate 9, and the side wall of the push plate 9 is fixedly connected with an L-shaped rod 11.

[0038] The lower surface of the top of the hollow disk 2 is rotatably connected to a turntable 12 through a telescopic rod 1, and a cam groove 14 and a cam groove 2 15 are opened on the inner wall of the turntable 12. The L-shaped rod 10 and the L-shaped rod 2 11 are respectively rollingly matched with the inner walls of the cam groove 14 and the cam groove 2 15 through the balls 13 arranged at the ends.

[0039] The cam groove 1 14 and the cam groove 2 15 are respectively provided with cam groove 1 14a, cam groove 1 14b and cam groove 2 15a, cam groove 2 15b, the cam groove 1 14a has a smaller protrusion amplitude than the cam groove 2 15a, and the cam groove 1 14b has the same protrusion amplitude as the cam groove 2 15b.

[0040] The telescopic rod 1 is used to drive the turntable 12 to rotate, and the ball 13 moves along the cam groove 14 and the cam groove 2 15. When it moves to the cam groove 14b and the cam groove 2 15b, the L-shaped rod 10 and the L-shaped rod 2 11 simultaneously push the sampling tube 7 and the push plate 9 to move to the outside of the hollow disk 2 for sampling. After the sampling is completed, the turntable 12 is rotated again so that the sampling tube 7 and the push plate 9 can be simultaneously retracted into the hollow disk 2; when the soil sample needs to be taken out of the sampling tube 7, the turntable 12 is rotated so that the ball 13 moves to the cam groove 14a and the cam groove 2 15b. Since the protrusion amplitude of the cam groove 14a is smaller than the protrusion amplitude of the cam groove 2 15a, the moving speed of the push plate 9 and the L-shaped rod 2 11 is greater than the moving speed of the sampling tube 7 and the L-shaped rod 10, so that the soil can be pushed out by the push plate 9.

[0041] The device is provided with a turntable 12, a cam groove 14 and a cam groove 2 15, and utilizes the cooperation of the ball 13 and the cam groove 14 and the cam groove 2 15, so that the sampling tube 7 and the push plate 9 can be extended and recovered at the same time, and the sampling tube 7 and the push plate 9 can be extended at different speeds only by rotating the turntable 12, and the sampling tube 7 can be rotated in the process of extending with the cooperation of the limit column 6 and the limit groove 8, thereby realizing simple operation to realize multiple motion forms, simplifying the operation steps, and improving the linkage and convenience of use of the device.

[0042] like Figure 3 As shown, a plurality of pins are fixedly connected to the bottom of the hollow disk 2. The pins are arranged so that after the hollow disk 2 reaches the bottom of the sampling hole drilled in advance, the bottom soil can be inserted, thereby ensuring the stability of the hollow disk 2 when the telescopic rod 1 and the rotating disk 12 are rotated.

[0043] In this embodiment: when in use, first use a drilling tool to drill a hole, then insert the hollow disk 2 into the opened sampling hole, until the pin at the bottom of the hollow disk 2 reaches the bottom of the sampling hole and is inserted into the soil, thereby completing the fixation of the hollow disk 2, and then use the telescopic rod 1 to drive the turntable 12 to rotate. When the ball 13 moves to the cam groove 1 14b and the cam groove 2 15b in the cam groove 1 14 and the cam groove 2 15, the L-shaped rod 10 and the L-shaped rod 2 11 respectively drive the sampling tube 7 and the push plate 9 to move synchronously to the outside of the hollow disk 2. During the movement of the sampling tube 7, it is affected by the limit column 6 and the limit groove 8, so that the sampling tube 7 will rotate after moving horizontally for a distance. When the sampling tube 7 moves horizontally, it can collect soil into it. When the sampling tube 7 rotates, There is a relative movement between the separation plate 5 and the soil, so that the separation plate 5 can be used to separate the soil, thereby ensuring that an appropriate amount of soil can be effectively collected in the sampling tube 7. After the sampling is completed, the telescopic rod 1 and the turntable 12 continue to be rotated, so that with the cooperation of the ball 13 and the cam groove 14 and the cam groove 2, the sampling tube 7 and the push plate 9 can be synchronously recovered into the hollow disk 2; when it is necessary to take the soil out of the sampling tube 7, the telescopic rod 1 and the turntable 12 are rotated until the ball 13 moves to the cam groove 14a and the cam groove 2 15a. Since the protrusion amplitude of the cam groove 14a is smaller than the protrusion amplitude of the cam groove 2 15a, the moving speed of the push plate 9 and the L-shaped rod 2 11 is greater than the moving speed of the sampling tube 7 and the L-shaped rod 10, so that the soil can be smoothly pushed out by the push plate 9.

[0044] Embodiment 2:

[0045] A geological detection sampling device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 6 As shown:

[0046] The telescopic rod 1 includes a moving rod 18 and a rod sleeve 22 . The moving rod 18 can only be slidably matched with the inner wall of the rod sleeve 22 . One end of the rod sleeve 22 passes through and is fixedly connected to the top of the rotating disk 12 .

[0047] The top of the movable rod 18 is fixedly connected with a handle 17, the outer wall of the movable rod 18 is provided with a slide groove 21, the inner wall of the rod sleeve 22 is threadedly connected with a threaded rod 20, the threaded rod 20 is slidably fitted in the inner wall of the slide groove 21, and the two ends of the threaded rod 20 are respectively fixedly connected with a knob 19 and an anti-slip pad.

[0048] In this embodiment: when the nail is inserted into the soil and the hollow disk 2 is fixed, the handle 17 is turned to drive the moving rod 18, the rod sleeve 22 and the turntable 12 to rotate; when the length of the telescopic rod 1 needs to be adjusted, the knob 19 is rotated to drive the threaded rod 20 and the anti-skid pad to break away from the restriction of the slide groove 21, so that the moving rod 18 can slide along the inner wall of the rod sleeve 22, thereby adjusting the extension length of the moving rod 18. After the adjustment is completed, the knob 19 is rotated again to drive the threaded rod 20 and the anti-skid pad to move toward the slide groove 21 until the anti-skid pad fits into the slide groove 21 and maintains a certain pressure, thereby completing the fixation between the moving rod 18 and the rod sleeve 22.

[0049] By providing the moving rod 18 and the rod sleeve 22, the device can adjust the extension length of the moving rod 18 according to sampling needs, so that the device can sample soils at different depths, thereby improving the flexibility of the device.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
