Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for soil detection. Background Art

[0002] Sampling involves extracting a representative portion of material from the entire batch of materials whose quality is to be determined in order to test the quality or determine the properties of the batch. Proper quality evaluation requires material that is representative of the entire sample, and obtaining representative material requires a standardized sampling system. Sampling is key to conducting a correct quality evaluation and is also an important step in obtaining reliable analytical results. Sampling methods vary depending on the state of the material.

[0003] For the sampling device for soil testing, it is not just about sampling the surface of the soil. Soil of different depths should be sampled at the same place to improve the accuracy of soil testing. At the same time, deep soil sampling requires a sampling device that can penetrate into the bottom of the soil layer. For this purpose, this scheme proposes a sampling device for soil testing. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sampling device for soil testing includes a base plate and a sampling block. A limiting column is provided on the base plate. Three groups of first limiting holes are provided on the limiting column. A group of triangular protrusions are provided on the first limiting hole. A second limiting hole is provided on the limiting column. A sampling plate is matched with the second limiting hole. A sampling groove is provided on the sampling plate. An inclined surface is provided at one end of the sampling plate. A third limiting hole is provided on the sampling plate. A top plate is provided on the sampling plate. A first right-angle plate is provided on the top plate. The sampling block is matched with the first limiting hole. A right-angle handle is provided on the sampling block. One end of the right-angle handle is curved. An anti-slip groove is provided on the sampling block, and a group of protrusions are provided on the sampling block.

[0007] Preferably, a vertical plate is provided on the bottom plate, a first hydraulic telescopic cylinder is provided on the vertical plate, and one end of the first hydraulic telescopic cylinder is in contact with the first right-angle plate.

[0008] Preferably, a second hydraulic telescopic cylinder is provided on the bottom plate, a fixed block is provided on the second hydraulic telescopic cylinder, and a limit plate is provided on the fixed block.

[0009] Preferably, a rectangular hole is opened on the fixing block, a limiting block is fitted in the hole, a pulling plate is provided on the limiting block, and the pulling plate is in contact with the limiting plate.

[0010] Preferably, the limiting block is fitted on the third limiting hole.

[0011] The utility model has the following beneficial effects:

[0012] The sampling plate is inserted into the soil layer, thereby filling the sampling groove with soil, and then the sampling plate is taken out, and finally the sampling block is inserted into the first limiting hole on the limiting column. Under the action of the triangular protruding block, the inner sides of the side plates on both sides are offset during the inward movement of the sampling block, so that the soil of a certain layer of the sampling groove is embedded in the sampling block. Under the action of the anti-slip groove and the protruding block, the soil of a certain layer of the sampling groove can be taken out, thereby facilitating the inspection of each layer of soil. By unfolding the first hydraulic telescopic cylinder, the first right-angle plate, the top plate and the sampling plate are driven to move downward, so that the sampling plate is probed deep into the soil layer, thereby facilitating sampling. By pushing and pulling the plate, the limiting block is inserted into the third limiting hole on the sampling plate, and then the second hydraulic telescopic cylinder is unfolded to drive the fixed block and the sampling plate to move upward, thereby facilitating sampling.
