The bottom plate 1 can be used once (matched with the transparent sealing cover for soil sample display) or repeatedly according to actual use requirements.

[0049] The working process is as follows:

[0050] First separate the upper frame 3 from the cover 2, then separate the upper frame 3 from the lower frame 4, hold the handle 45, place the sawtooth end against the soil profile, and then hit the flexible layer with a hammer so that the sawtooth end draws a rectangular sampling range (i.e., soil sample) in the soil profile.

[0051] Then use external tools to dig out the position outside the sampling range to protrude the soil sample.

[0052] The upper frame 3 and the lower frame 4 are fixed by two first connecting bolts 11, and the handle 45 is held to put the protruding sampling range into the sampling space.

[0053] The protruding soil sample is then cut off by a saw blade or metal wire so that the soil sample is within the sampling range.

[0054] Finally, the staff pushes the metal wire 61 to slide through the two push rods 63 to trim the soil sample again to ensure the flatness of the soil sample, and then fixes the cover body 2 and the upper frame body 3 with two second connecting bolts 22 to complete the collection of the entire soil sample.
