Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a soil and rock sampling device for water conservancy engineering testing. Background Technology
[0002] During the construction of water conservancy projects, it is necessary to conduct testing and investigation of the foundation rocks, and to investigate the basic characteristics and spatial distribution of the soil and rock mass, groundwater and adverse geological processes below the surface, so as to ensure the smooth progress of subsequent work. Sampling is to take soil and rock and groundwater samples that meet various specific quality requirements during the on-site exploration process using certain technical means.
[0003] According to Chinese Patent Publication No. CN219870352U, a soil and rock sampling device for water conservancy engineering testing is disclosed. This device, through a sampling mechanism and a screw-slider threaded connection, allows the slider to slide within a transmission groove, effectively ensuring the stability of the sampling device during operation and preventing deviation during drilling, thus improving drilling efficiency. The indicator plate and scale allow for accurate measurement of the drilling depth into the soil and rock. However, in this technical solution, the entire sampling device is fixed to the ground using ground nails. This necessitates removing the ground nails and moving the entire sampling device when sampling soil and rock at different locations, resulting in cumbersome operation, wasted manpower, and significantly impacting sampling efficiency. Therefore, we propose a soil and rock sampling device for water conservancy engineering testing. Utility Model Content

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a soil and rock sampling device for water conservancy engineering testing, including a support plate 1 and a sampling cylinder 10. A support leg 22 is fixedly installed at the bottom end of the support plate 1, and a caster wheel 23 is installed at the bottom end of the support leg 22. An anchor rod 24 is movably connected through the support plate 1. A fixed frame 2 is fixedly installed at the top end of the support plate 1.

A movable block 4 is slidably connected to the inner wall of the movable frame 3. A hydraulic cylinder 5 is fixedly installed at the top end of the movable block 4. The piston rod of the hydraulic cylinder 5 movably passes through the... The piston rod of the moving block 4 and the hydraulic cylinder 5 is fixedly mounted with a connecting frame 6. The inner wall of the connecting frame 6 is fixedly mounted with a motor 7. The output end of the motor 7 is fixedly mounted with a rotating shaft 8. The rotating shaft 8 movably passes through the bottom end of the connecting frame 6. The outer wall of the rotating shaft 8 is fixedly mounted with a spiral blade 9. The sampling cylinder 10 is set outside the spiral blade 9 and is fixedly mounted on the outer wall of the rotating shaft. The inner wall of the moving frame 3 is rotatably connected to a screw 20 through a bearing seat. The moving block 4 is threaded onto the outer wall of the screw 20. The top of the moving frame 3 is equipped with a motor 15. The screw 20 is connected to the motor 15 for transmission.
[0025] Furthermore, a support groove 12 is provided on the inner wall of the adjustment port 21, and support slide plates 11 are fixedly installed on both sides of the moving frame 3. The support slide plates 11 are slidably connected to the inner wall of the support groove 12.
[0026] By setting the support slide plate 11 and the support slide groove 12, the moving frame 3 can be supported and limited, so that the moving frame 3 can be fixed and slid on the fixed frame 2.
[0027] Furthermore, an electric slide rail 13 is fixedly installed on the inner wall of the support slide 12, and the support slide plate 11 is slidably connected to the electric slide rail 13.
[0028] Among them, by setting up an electric slide rail 13, the electric slide rail 13 can drive the moving frame 3 to move through the supporting slide plate 11.
[0029] Furthermore, a limiting slide plate 25 is fixedly installed on the outer wall of the movable block 4, and a limiting slide groove 26 is opened on the inner wall of the movable frame 3. The limiting slide plate 25 is slidably connected to the limiting slide groove 26, and a sampling port 27 is opened on the support plate 1.
[0030] The limiting slide plate 25 and the limiting slide groove 26 can limit the movement block 4, so that the movement block 4 can slide in a fixed position on the moving frame 3.

[0034] Specifically, in the above technical solution, when using the soil and rock sampling device for water conservancy engineering testing, the device is moved to the location where sampling is required, and then fixed to the ground by anchor bolts 24. Then, hydraulic cylinder 5 and motor 7 are activated. Motor 7 drives the sampling cylinder 10 and spiral blade 9 to rotate via a rotating shaft. Hydraulic cylinder 5 drives motor 7 downwards via connecting frame 6. Connecting frame 6 drives sampling cylinder 10 and spiral blade 9 downwards via support rods and rotating shaft, allowing sampling cylinder 10 to pass through sampling port 27 and ultimately insert into the soil and rock. The spiral blade 9 then... The sample is conveyed to the sampling cylinder 10. After the soil and rock are conveyed, the hydraulic cylinder 5 is activated to move the connecting frame 6 upward, causing the sampling cylinder 10 to detach from the soil and rock surface. The motor 7 is then activated to rotate, causing the spiral blade 9 to discharge the soil and rock sample from the sampling cylinder 10, thus completing the sampling at that location. When continuous sampling is required at different locations, the electric slide rail 13 can be activated, causing the electric slide rail 13 to move the moving frame 3 forward or backward via the support slide plate 11. The motor 15 is then activated, causing the motor 15 to drive the synchronous pulley 17 to rotate via the rotating shaft 16. The synchronous pulley 17... The synchronous belt 19 drives the synchronous pulley 18 to rotate, which in turn drives the screw 20 to rotate. The screw 20 can then move the moving block 4 laterally. By rotating the motor 15 in both directions, the moving block 4 can be moved left or right, thus allowing direct adjustment of the sampling position of the sampling cylinder 10 above the soil and rock. After adjustment, the initial sampling steps are repeated to complete the sampling. This structure allows for easy adjustment of the sampling position when multiple samples are needed for testing and verification, eliminating the need for personnel to move the entire device and greatly improving sampling efficiency. This invention improves efficiency and saves manpower. It solves the problem that in existing technical solutions, the entire sampling device is fixed to the ground by ground nails, which requires personnel to remove the ground nails and move the entire sampling device when sampling soil and rock at different locations. This operation is cumbersome, wastes manpower, and greatly affects sampling efficiency. By setting a support rod, the sampling cylinder 10 can be supported and limited. Furthermore, by setting ball bearings, the friction between the support rod and the connecting frame 6 can be reduced, ensuring the flexibility of the sampling cylinder 10 during rotation. The structure is simple and highly practical.
