Description
Technical field
The utility model relates to a kind of collecting soil sample field more particularly to a kind of thin solum undisturbed samplers.
Background technique
Existing soil sampler type is more, can be divided mainly into two class of mechanical sampling device and hand sampling device.Wherein machine
Tool sampler is mainly made of units such as sampling head, connecting rod and power drive units, and manually operated earth boring auger style is also very much,
There is the short handle earth boring auger of acquisition shallow-layer soil sample, observe the screw terminal earth boring auger of 1 meter or so soil layer interior profile feature, the latter's dynamic soil is adopted
Sample device is laborsaving into soil, is particularly suitable for observation WATER LEVEL CHANGES, but it is small to acquire soil sample amount.Acquisition is for chemical analysis or is not required to original
When the soil sample of the physical analysis of shape soil, with open type earth boring auger；Acquisition does not destroy the undisturbed soil sample of soil texture or shape, with set
Cartridge type earth boring auger.
Existing undisturbed machinery is adopted earth boring auger and is usually driven by motor, and drill body is made to enter the soil of certain depth, then will
Earth pillar is put on, and observation is laid flat, as needed cutting sampling.Earth pillar diameter can be controlled with the drill body of different-diameter, such as 5 centimetres, 10
Centimetre or it is thicker.Power auger is high-efficient, can save manpower, but flexible, light not as good as hand drill.Such as existing undisturbed sampling
Device Geoprobe, the equipment volume is larger, has higher requirement to landform and operating environment, is not suitable for complicated landform and interior
Sampling operation.
Existing hand-operated soil sampler simple structure, is easy to carry about with one and carries, but sampling process expends a large amount of manpowers, especially
It is the acquisition for deep soil sample, needs hand excavation ground to cooperate, has some limitations.In addition, because
The promotion of testing requirements at present proposes harsh undisturbed sampling request to the measurement of soil volatile materials, general
Hand sampling equipment is unable to reach the requirement.
