The sampling tube 40 is inserted into the outer sleeve assembly 20, a cavity 25 is formed by surrounding the outer side wall of the sampling tube 40, the inner side wall of the outer sleeve 21, the bottom surface of the first mounting cylinder 13 and the top surface of the positioning ring 24, and the cavity 25 is communicated with the vent hole 231. The outer sidewall of the upper portion of the sampling tube 40 is provided with a first external thread that mates with a first internal thread. The upper portion of the sampling tube 40 is further provided with a mounting block 43, and the mounting block 43 is provided with a pointer (not shown) and a mounting hole 431 penetrating up and down.

The bottom plate assembly 65 includes a floating plate 651, a sinking plate 652 and a guide rod 653, the floating plate 651 is fixedly connected with the bottom of the first water suction pipe 61, an inlet of the water suction pipe 64 is located at the side of the floating plate 651, an outlet of the water suction pipe 64 is communicated with an inner cavity of the first water suction pipe 61, the sinking plate 652 is located below the floating plate 651 and is connected with the bottom of the guide rod 653, the guide rod 653 longitudinally penetrates through the floating plate 651, and a limiting portion 654 is arranged at the upper end of the guide rod 653, therefore, the guide rod 653 and the sinking plate 652 can move up and down relative to the floating plate 651, and the guide rod 653 can be limited to move downwards to be separated from the floating plate 651. The longitudinal projection of the bottom plate assembly 65 coincides with the longitudinal projection of the lumen of the sampling tube 40, and the longitudinal projection areas of both the floating plate 651 and the sinking plate 652 are smaller than the longitudinal projection area of the lumen of the sampling tube 40.
As one way, when the bottom surface of the sinking plate 652 is flush with the bottom edge of the sampling tube 40 and the floating plate 651 moves down to abut against the sinking plate 652, the value of the scale bar indicated by the pointer is a reference value, and the position of the scale bar can be designed so that the reference value is zero. When the bottom plate assembly 65 and the first suction pipe 61 are put in water, the sinking plate 652 will sink into the water due to its high density; the floating plate 651 has a smaller density and can float on water, and the buoyancy provided by the water to the floating plate 651 can support the first suction pipe 61 and the sinking plate 652, prevent the floating plate 651 from sinking below the water surface, and enable the inlet of the water guide pipe 64 to be located below the water surface.
In the above manner, in operation, the first bracket 11 is fixed on the shore or the ship, the bolt 70 is inserted into the outer sleeve 21 and the sampling tube 40, and the bottom edge of the sampling tube 40 may be flush with the bottom edge of the conical head 22; the rotating member 51 operates to drive the outer jacket assembly 20 and the sampling tube 40 downward through the water layer until inserted into the soil, the floating plate 651 floats on the water, and the first suction tube 61 moves upward relative to the sampling tube 40; the water pump 62 is operated to pump out the water in the sampling tube 40 through the water guide tube 64 and the first suction tube 61, and the floating plate 651 and the first suction tube 61 gradually move downward as the water level of the sampling tube 40 is lowered; when the sinking plate 652 falls onto the soil layer and the floating plate 651 moves down to abut against the sinking plate 652, the first suction pipe 61 moves down to the bottom, the water in the sampling pipe 40 is evacuated, and at this time, the difference between the numerical value of the scale bar indicated by the pointer and the aforementioned reference value is the depth of the sampling pipe 40 inserted into the soil layer; if the depth of the sampling tube 40 inserted into the soil layer reaches the set value, the latch 70 is pulled out to rotate the sampling tube 40 upwards, and if the depth of the sampling tube 40 inserted into the soil layer does not reach the set value, the rotating member 51 continues to operate to enable the sampling tube 40 to continue to move downwards, and then the latch 70 is pulled out to rotate the sampling tube 40 upwards. After sampling tube 40 is removed from housing assembly 20, first barrel 61 may be depressed to push out the soil within sampling tube 40 through bottom plate assembly 65.
Through the structure, water in the sampling pipe 40 can be discharged, the influence on the operator to take out the soil in the sampling pipe 40 is avoided, the depth of the sampling pipe 40 inserted into the soil layer can be determined through the numerical value indicated by the pointer, the soil with proper depth is not required to be collected in a multi-time probing mode, and the sampling operation of the operator is simplified.

In the process of rotating and moving up the sampling tube 40, the bottom edge of the sampling tube 40 sequentially passes through the conical head 22, the sealing ring 30 and the positioning ring 24: after the bottom edge of the sampling tube 40 passes through the positioning ring 24, the cavity 25 is communicated with the space below the sampling tube 40, and the outside air enters the space below the sampling tube 40 through the vent hole 231 and the cavity 25, so that the air pressure can be balanced, the negative pressure formed below the sampling tube 40 is avoided to influence the upward movement of the sampling tube 40, and the resistance of the upward movement of the sampling tube 40 is reduced. By providing the sealing ring 30, water is prevented from entering the cavity 25 between the sampling tube 40 and the outer housing assembly 20 during insertion of the outer housing assembly 20 into the water; during the upward movement of the sampling tube 40, the outer sleeve assembly 20 may block water from entering the inside thereof and contacting the outside wall of the sampling tube 40. Thus, through the structure, the soil at the bottom of the inner cavity of the sampling tube 40 can be prevented from contacting water, the soil at the bottom of the inner cavity of the sampling tube 40 is prevented from falling apart from the sampling tube 40 due to water absorption, the loss of a soil sample is avoided, and the analysis error of the water content of the soil can be reduced.
The depth of insertion of the sheathing member 20 into the soil layer is generally 20cm or more, and when the surface of the soil layer is silt, the depth of insertion is appropriately increased so that the bottom edge of the sheathing member 20 is positioned under the silt layer. The outer side wall of the housing assembly 20 contacts the soil and forms a seal with the soil to prevent water from penetrating down the sampling tube 40 along the outer side wall of the housing assembly 20 and between the soil.
