Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling and relates to a soil sampling device before water conservancy construction. Background Art

[0002] During the survey of water conservancy projects, in order to meet the requirements of full-layer, equal-amount and convenient soil sampling, people use soil samplers to conduct soil sampling research.

[0003] The existing Chinese patent application number is CN216247321U, and the name is a patent for a soil sampling device for water conservancy projects. The background technology of the patent clearly records that "when the common sampling devices on the market are used in water conservancy projects, the soil around the water conservancy projects is often relatively soft, and the device cannot be well contacted and fixed with the ground, resulting in poor overall stability of the device during sampling." This technical solution solves this problem through specific technical means. However, in this technology, when the staff completes the sampling, it is difficult to remove the soil sample from the sampling device, which is easy to damage the soil sample. The soil sample taken out is often not formed, resulting in the mixing of samples from each soil layer, reducing the accuracy of subsequent detection; and in the process of removing the soil sample, it is easy to cause contamination to the soil sample, which will also reduce the accuracy of subsequent detection.

[0027] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0028] The utility model discloses a soil sampling device before water conservancy construction, such as Figure 1 As shown, including:

[0032] The sampling tube 8 also includes a sample barrel 13, which is arranged inside the driving tube 9; a top plate 14 is embedded in the sample barrel 13, and the top plate 14 is in the shape of a disc, and its size is adapted to the inside of the driving tube 9, and it can slide inside the driving tube 9.

In this process, the staff will not directly contact the soil sample, which can avoid contamination of the soil sample.

[0033] Furthermore, the top plate 14 is clearance-matched with the sample tube 13, so that the top plate 14 can be moved more easily in the sample tube 13, thereby improving the efficiency of taking out soil samples.

[0043] Then the connecting rod 3 is adjusted to a suitable length, and the frame is further fixed by the positioning pin 5 in the fixing ring 4. Then the soil sampling device 6 is started, and the soil sampling device 6 drives the driving pipe 9 to drill into the ground to sample the soil.
