The existing geotechnical sampling device usually adopts a triangular support for support. However, in the actual working environment, the ground is often uneven. The height of the traditional triangular support leg is fixed, or only the overall height can be adjusted, and the height of a certain leg cannot be adjusted individually. This results in difficulty in leveling the triangular support on uneven ground, which affects the stability of the sampling mechanism and the accuracy of sampling, reduces the work efficiency, and increases the sampling error.

[0019] Embodiment 1

[0020] As shown in the figure. Figures 1-5

[0021] A rock-soil sampling device in geotechnical engineering.

[0022] In the embodiment: to solve the technical problems existing in the prior art, as disclosed in the background art above, "the existing rock-soil sampling device usually adopts a triangular support for support, however, in the actual working environment, the ground is often uneven. The height of the traditional triangular support leg is fixed, or only the overall height can be adjusted, and it cannot be adjusted individually for a certain leg. This leads to the difficulty of leveling the triangular support on uneven ground, thereby affecting the stability of the sampling mechanism and the accuracy of sampling, reducing the work efficiency and increasing the sampling error", in combination with the actual use, this problem is obviously a real problem and is relatively difficult to solve. Therefore, to solve this technical problem, a rock-soil sampling device in geotechnical engineering is provided on this basis.

[0023] As shown in the figure. Figures 1-5

[0024] In combination with the above content, including a triangular support 1 and a sampling mechanism 2 arranged on the triangular support 1, triangular bottom ends of the triangular support 1 are provided with bolts 4 through height adjusting mechanisms 3, the height adjusting mechanisms 3 include rectangular supports 31 fixed at bottom ends of the triangular support 1, limiting sliding holes 32 are formed in the rectangular supports 31, the bolts 4 slide up and down inside the limiting sliding holes 32, driven gears 33 and driving gears 34 are movably arranged on the rectangular supports 31 through bearings, threaded holes 35 are formed at centers of the driven gears 33, screw rods 36 are arranged inside the threaded holes 35, bottom ends of the screw rods 36 are fixedly connected with top ends of the bolts 4, and rotating handles 37 are arranged on one side of the driving gears 34 through support rods.

[0025] ​​The triangular support 1 is composed of three telescopic supporting rods, which include an inner rod and an outer rod sleeved outside the inner rod, and a locking mechanism is arranged between the inner rod and the outer rod.

[0026] The driven gear 33 is in mesh with a driving gear 34, and the diameter of the driving gear 34 is larger than that of the driven gear 33.

[0027] The bottom end of the plug 4 is conical.

[0028] The surface of the rotating handle 37 is provided with an anti-skid rubber sleeve, and the surface of the anti-skid rubber sleeve is provided with a plurality of protruding anti-skid particles.

[0029] The plug 4 is limited in the limiting sliding hole 32 and slides up and down in the limiting sliding hole 32.

[0030] The top of the triangular support 1 is provided with a level.

[0031] When the device is used, first, the device is moved to the sampling site. The level at the top of the triangular support is observed. If the level shows that the triangular support is not horizontal, the rotating handle corresponding to the supporting leg that needs to be adjusted in height is rotated according to the indication of the level.

[0032] For example, if the left supporting leg of the triangular support is lower, causing the device to tilt to the left, the rotating handle at the left supporting leg is held and rotated clockwise (determined according to the direction of gear transmission, which is only an example here), the driving gear drives the driven gear to rotate, and the driven gear drives the screw rod to move downward through the cooperation of the threaded hole and the screw rod, so that the plug moves downward and the height of the left supporting leg is increased.

[0033] During the adjustment process, the level is continuously observed until the level shows that the triangular support is in a horizontal state. If it is necessary to adjust the overall height of the triangular support, the locking mechanism on the supporting rod is loosened, the telescopic length of the inner rod in the outer rod is adjusted, and after the adjustment is completed, the locking mechanism is locked again.

[0034] When the triangular support is leveled and the height is appropriate, the rock-soil sampling work can be carried out through the sampling mechanism. After the sampling is completed, the rotating handle is counterclockwise rotated, the plug is pulled out of the ground, and the device is collected for next use.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
