Technical Field
[0001] This utility model relates to the technical field of soil sampling, and more specifically, to a series-connected soil sampling device with geotextile ring cutters. Background Technology
[0002] Geotechnical sampling refers to the technical operation of obtaining samples for geotechnical testing. Identification soil samples or disturbed soil samples must retain their solid components for classification tests and stratigraphic identification. Disturbed soil samples are soil samples obtained from the ground using a shovel or drill; their shape and density differ from the original soil, and they are suitable for some soil physical tests.
[0003] Traditional geosampling methods often employ manual digging or simple mechanical drilling, which are not only inefficient but also fail to guarantee the integrity and representativeness of the samples. To address these issues, we provide a tandem soil sampling device with geotextile ring cutters.
[0004] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0008] By adopting the above technical solution, geotechnical samples can be collected quickly and easily, and stratified sampling is also possible. When used in the laboratory, geotechnical sampling can be completed relatively quickly.
[0009] Preferably, the inside of the arc-shaped cylinder is provided with multiple placement slots, and the ring cutter is arranged in the placement slots.
[0010] By adopting the above technical solution, the ring cutter can be easily placed inside the arc-shaped cylinder, and the ring cutter can be prevented from moving up and down inside the arc-shaped cylinder.
[0011] Preferably, the placement slots are arranged at equal intervals.
[0012] By adopting the above technical solution, the maximum number of ring cutters assembled inside the arc-shaped cylinder can be guaranteed.
[0013] Preferably, both of the arc-shaped cylinders are provided with insert covers at their bottoms.
[0014] By adopting the above technical solution and setting the insert cover, the arc-shaped cylinder can be easily inserted into the lower sleeve.
[0015] Preferably, the bottom of the lower sleeve is chamfered.
[0016] Preferably, the bottom of the ring cutter is chamfered.
[0017] Preferably, the top of the upper sleeve has a threaded groove for connecting an external drive component.
[0018] Preferably, the driving component is a hydraulic cylinder.
[0019] In summary, this utility model has the following beneficial technical effects:

Then, the lower sleeve is aligned with the soil to be sampled, and the arc-shaped cylinder is driven into the soil by pushing down the upper sleeve. Soil can be retained in each ring cutter. The soil is then removed from the sampling device, and the upper and lower sleeves are disassembled. The two arc-shaped cylinders are opened, and each ring cutter is removed in turn to complete the soil sampling. This structural design facilitates the rapid collection of geotechnical samples and allows for layered sampling. When used in the laboratory, geotechnical sampling can be completed quickly.
[0021] Furthermore, the soil sample is encased in a ring cutter, which prevents the soil sample from being contaminated and ensures the integrity of the soil.

[0031] This utility model discloses a series-connected soil sampling device with a geotextile ring cutter. (Refer to...) Figures 1 to 4 A series soil sampling device with geotechnical ring cutters includes an upper sleeve 1, a lower sleeve 2, two arc-shaped cylinders 3 and several ring cutters 4; each ring cutter 4 is arranged in series between the two arc-shaped cylinders 3, the upper sleeve 1 is located at the top of the two arc-shaped cylinders 3 and the lower sleeve 2 is located at the bottom of the two arc-shaped cylinders 3.
[0032] In this embodiment, the sampling device is installed by placing each ring cutter 4 inside two arc-shaped cylinders 3, and then connecting the upper sleeve 1 and the lower sleeve 2 to the top and bottom of the two arc-shaped cylinders 3 respectively. Next, the lower sleeve 2 is aligned with the soil to be sampled, and the arc-shaped cylinder 3 is driven into the soil by pushing down the upper sleeve 1. Soil can be retained inside each ring cutter 4. Then, the soil is removed from the sampling device, and the upper sleeve 1 and the lower sleeve 2 are disassembled. The two arc-shaped cylinders 3 are opened, and each ring cutter 4 is removed in turn to complete the soil sampling. This structural design facilitates the rapid collection of soil samples and allows for layered sampling. When used in the laboratory, soil sampling can be completed quickly, and the soil sample is enclosed by the ring cutter 4, which can prevent soil contamination.
[0033] like Figure 3 As shown, the inside of the arc-shaped cylinder 3 is provided with multiple placement slots 5, and the ring cutter 4 is arranged in the placement slots 5.
[0034] Specifically, this design allows the ring cutter 4 to be placed inside the arc-shaped cylinder 3, and prevents the ring cutter 4 from moving up and down inside the arc-shaped cylinder 3.
[0035] like Figure 3 As shown, the placement slots 5 are arranged at equal intervals.
[0036] Specifically, this design ensures that the number of inner ring cutters 4 in the arc-shaped cylinder 3 is maximized.
[0037] like Figure 3 As shown, both arc-shaped cylinders 3 have insert covers 6 at their bottoms.
[0038] Specifically, by setting the insert cover 6, the arc-shaped cylinder 3 can be easily inserted into the lower sleeve 2.
[0039] like Figure 3 As shown, the bottom of the lower sleeve 2 is beveled.
[0040] like Figure 4 As shown, the bottom of the ring cutter 4 is chamfered.
[0041] Example 2
[0042] This embodiment is a further optimization based on the above embodiments. The parts that are the same as those in the foregoing technical solutions will not be repeated here. Figure 1 As shown, in order to better realize this utility model, the following setting method is adopted: In this embodiment, the top of the upper sleeve 1 is provided with a threaded groove 7 for connecting an external driving component.
[0043] Specifically, the driving component is a hydraulic cylinder.
[0044] By opening a threaded groove 7 at the top of the upper sleeve 1 and connecting it to an external drive unit, the sampling device can be moved up and down by the drive unit to perform soil sampling.

The machinery, parts and equipment adopt conventional models in the existing technology, which will not be described in detail here.
[0046] The implementation principle of a series-connected soil sampling device with geotechnical ring cutters according to this utility model embodiment is as follows: By placing each ring cutter 4 inside two arc-shaped cylinders 3, and then connecting the upper sleeve 1 and the lower sleeve 2 to the top and bottom of the two arc-shaped cylinders 3 respectively, the sampling device is installed. Then, the lower sleeve 2 is aligned with the soil to be sampled, and the upper sleeve 1 is pushed down to insert the arc-shaped cylinder 3 into the soil, so that soil can be retained in each ring cutter 4. Then, the soil is removed from the sampling device, and the upper sleeve 1 and the lower sleeve 2 are disassembled. The two arc-shaped cylinders 3 are opened, and each ring cutter 4 is removed in turn, thus completing the soil sampling. Through this structural design, it is convenient to quickly collect geotechnical samples, and it can sample in layers. When used in the laboratory, geotechnical sampling can be completed quickly.
[0047] Alternatively, a threaded groove 7 can be opened at the top of the upper sleeve 1 and connected to an external drive unit, thereby driving the sampling device to move up and down to perform soil sampling.
