FIG. 2
[0001] This invention relates to the technical field of undisturbed soil sampling, in
particular to a fast sampling apparatus for surface undisturbed soil.
[0002] Undisturbed soil refers to a soil sample that retains the original structure of the
soil during the sampling process; undisturbed soil plays an important role in carrying
out soil erosion tests, soil aggregate tests, and soil nutrient analysis; soil sampling
device refers to tools used to obtain soil samples; commonly used are soil drills and
shovel.
[0003] The shape of the cutter head of the current soil extractor in the prior art is
mostly circular, and most of the soil samples collected are of cylindrical structure;
said type of soil extractor is mainly used to collect deep soil samples; said sampling
methods mostly use manual or mechanical power to rotate the handle to damage the
soil structure by rotating and cutting; said method can basically guarantee the original
condition of the soil sample; however, due to said rotation method, while cutting the
root system in the soil, if it cannot be cut immediately, the root system will be dragged,
thereby destroying the original structure of the soil;
[0004] On the other hand, although the existing soil sampling devices on the market
have been widely used for soil analysis sampling and geotechnical test sampling,
there are still some devices for tests such as topsoil stripping, aggregate analysis,
water erosion or wind erosion tests that still require rectangular undisturbed soil; if
said circular soil extractor is used to take soil, there will be large gap between the soil
sample and the test device.
[0005] Meanwhile, some tests have higher requirements for root structure in
undisturbed soil; it is necessary to preserve the original structure of vegetation-surface
soil-root system at the same time; said traditional rotating cylindrical soil sampling
device cannot meet the above requirements; therefore, it is needed to design a surface
soil sampling device with simple structure, reasonable size and convenient sampling.
[0006] Purpose of this invention is to solve the defects in the prior art, and proposes a
fast sampling apparatus for surface undisturbed soil.
[0007] This invention adopts the following technical solutions to achieve the

plate; said positioning mechanism includes sleeve fixed on the outer wall of the
movable side plate; said slider is slidably provided in the sleeve; one end of said slider
that is away from the sleeve is slidingly fitted with said vertical chute; diameter of
said slider is slightly smaller than the aperture of the positioning concave hole; said
shaft is fixed at the other end of the slider; said shaft slides through to the outside of
the sleeve; said sleeve is provided with spring wound on said shaft.
