[0023] In this embodiment, Figure 3As shown, the sampling tube assembly 4 is composed of a sampling tube 401, a fixed collar 402, a telescopic rod 403 and a connecting sleeve rod 404, wherein one end of the connecting sleeve rod 404 is sleeved on the outer wall of the rotating bolt 3, and the other end is sleeved on the top of the telescopic rod 403, and the fixing collar 402 is also inserted at the bottom end of the telescopic rod 403, and the sampling tube 401 is clamped on the inner wall of the fixing collar 402; it should be noted that when the operator lifts the obtained water and soil samples upward to the discharge pipe 1102 through the hydraulic cylinder 9 and the sampling block 10, at the same time, the operator can manually rotate the rotating bolt 3 first, and drive the empty sampling tube 401 to rotate to the discharge pipe 1102 through the connecting sleeve rod 404.

After completing a sampling, the operator can then manually rotate the rotating bolt 3 to rotate the other empty sampling tubes 401 to the outlet of the discharge pipe 1102, and complete continuous sampling at one time.

[0024] In this embodiment, Figure 2 and Figure 4 As shown, the hydraulic cylinder 9 and the sampling block 10 arranged at its bottom together constitute a sampling mechanism; it should be noted that before performing the sampling operation, the operator needs to start the hydraulic cylinder 9 first, so that its driving end pushes the sampling block 10 connected thereto to descend to a position flush with the sampling port 1101 just above the sampling port, and then after starting the driving motor 7 to drive the threaded drill barrel 11 to rotate and penetrate deep into the soil, the soil will enter the threaded drill barrel 11 through the sampling port 1101 opened at the bottom end of the threaded drill barrel 11. At the same time, the soil will be squeezed through the sampling ports 1101 opened on the surfaces of the top block 1002 and the bottom block 1003. The gap enters into the threaded drill barrel 11 just above the rotating stop block 1006 and is collected. After reaching a certain amount of sample, the operator can start the micro motor 1004 to drive the rotating stop block 1006 to rotate, so that the rotating stop block 1006 seals and blocks the gaps opened on the surfaces of the top block 1002 and the bottom block 1003, and then drives the hydraulic cylinder 9 to cause its driving end to begin to retract to its original position. During this process, the closed sampling stop block 10 will push the water and soil samples placed on its top to be lifted to the discharge pipe 1102 of the threaded drill barrel 11, and fall into the sampling test tube 401 along the mouth of the discharge pipe 1102 to complete the sampling.

[0025] In this embodiment, Figure 4 and Figure 5 As shown, the sampling block 10 is composed of a fixed ring 1001, a top block 1002, a bottom block 1003, a micro motor 1004, a rotating shaft 1005, and a rotating block 1006. The inner wall of the fixed ring 1001 is sleeved on the outer walls of the top block 1002 and the bottom block 1003, and the micro motor 1004 is provided at the bottom center of the top block 1002. The output end of the micro motor 1004 is also plugged with the rotating shaft 1005. At the same time, the bottom end of the rotating shaft 1005 is rotatably connected to the top of the bottom block 1003, and during the rotation, the micro motor 1004 is rotated to rotate. The outer wall of the shaft 1005 is also provided with a rotating stopper 1006, and both the top block 1002 and the bottom block 1003 are provided with a notch that is the same as the depression of the rotating stopper 1006; it should be noted that before performing the sampling operation, the operator needs to start the hydraulic cylinder 9 first, so that its driving end pushes the sampling stopper 10 down to a position flush with the sampling port 1101, and then start the micro motor 1004 to make its output end start to rotate and drive the rotating shaft 1005 connected thereto to start rotating. At the same time, the sleeve The rotating block 1006 on the outer wall of the rotating shaft 1005 will be driven to rotate in contact with the annular inner wall of the fixed ring 1001 until the depression of the rotating block 1006 coincides with the gaps provided in the top block 1002 and the bottom block 1003, and the gaps are exposed. At the same time, the operator can start the driving motor 7 to drive the threaded drill barrel 11 to penetrate into the soil for sampling. At this time, the soil will enter from the sampling port 1101 and then be pressed into the threaded drill barrel 11 directly above the rotating block 1006 through the gap. After reaching a certain amount of sample, the operator can start the micro motor 1004 again to drive the rotating block 1006 to rotate back to its original position, seal the gaps opened on the surfaces of the top block 1002 and the bottom block 1003, and then start the hydraulic cylinder 9 to make its driving end begin to retract to its original position. During this period, the closed sampling block 10 will push the water and soil samples placed on its top to the discharge pipe 1102 of the threaded drill barrel 11, and fall into the sampling tube 401 along the mouth of the discharge pipe 1102 to complete the sampling.

[0026] In this embodiment, Figure 2 and Figure 4As shown, a sampling port 1101 is provided at the bottom end of the threaded drill barrel 11, and a discharge pipe 1102 is inserted into the outer wall of one side of the threaded drill barrel 11; it should be noted that after the operator firmly fixes the entire sampling device at the sampling location through the gripping mechanism 1, the operator can start the hydraulic cylinder 9 to push the sampling stop block 10 down to the top of the sampling port 1101, and start the micro motor 1004 to drive the rotating stop block 1006 to rotate, and expose the gap formed by the top block 1002 and the bottom block 1003. At the same time, the operator can start the driving motor 7 to make its output end start to rotate and drive the threaded drill barrel 11 to spirally penetrate into the soil through the connecting rotating rod 8 for sampling. In this process, as the threaded drill barrel 11 continues to penetrate into the soil, the crushed soil will be squeezed into the interior of the sampling port 1101 and passed through the top block 10 02 and the gap opened by the bottom block 1003 are pressed into the threaded drill barrel 11 just above the rotating stop block 1006. After reaching a certain amount of sample, the operator can start the micro motor 1004 again to drive the rotating stop block 1006 to rotate back to its original position, seal the gap opened on the surface of the top block 1002 and the bottom block 1003, and then start the hydraulic cylinder 9 to make its driving end begin to retract to its original position, thereby driving the water and soil samples placed on the top of the sampling stop block 10 to be lifted to the discharge pipe 1102 of the threaded drill barrel 11, and fall into the sampling tube 401 along the mouth of the discharge pipe 1102 to complete the sampling. After completing a sampling operation, the operator can manually turn the rotating bolt 3 to drive other empty sampling tubes 401 to rotate to the outlet of the discharge pipe 1102 through the connecting sleeve rod 404 for continuous sampling.

At the same time, the operator can start the driving motor 7 to drive the threaded drill tube 11 to penetrate into the soil for sampling. At this time, the soil will flow along the sampling port 1101. 101 enters the interior of the threaded drill barrel 11 and is pressed into the threaded drill barrel 11 just above the rotating stop block 1006 through the gap. After reaching a certain amount of sample, the operator can start the micro motor 1004 again to drive the rotating stop block 1006 to rotate back to its original position to seal the gap. At the same time, start the telescopic rod 403 to push multiple sampling tubes 401 down together until the mouth of one of the sampling tubes 401 drops to the outlet of the discharge pipe 1102. At this time, the hydraulic cylinder 9 can be restarted, and the closed sampling stop block 10 will drive the water and soil samples placed on the top of it to be lifted to the discharge pipe 1102 of the threaded drill barrel 11, and fall into the sampling tube 401 along the mouth of the discharge pipe 1102 to complete the sampling.
