As the utility model further scheme：The soil sample barrel and shoe bottom are equipped with the sword of introversion
Mouthful.
Compared with prior art, the beneficial effects of the utility model are：
Sampling efficiency is high, and speed is fast.Since the utility model can disposably take four samples, and without transporting experiment back
Room carries out machining, avoids the destruction of working angles the time it takes and soil sample, substantially increases the efficiency contracting of sampling
The process of short experiment.
The suffered disturbance of sample is small, as far as possible maintaining the original state property.Since soil sample barrel and shoe bottom are equipped with the sword of introversion
Mouthful, so drilling machine force is small when soil sampler is pressed into the soil body, the pressure suffered by the soil body is smaller, reduces caused by soil is pressurized
Disturbance.
In outer tube and shoe rotary course, internal structure is slided by sliding block in groove to keep internal structure
And the soil body does not rotate, and maintains the original state of the soil body.Outer tube can make the convex body movement of retainer end together with the rotation of shoe
To slide, it can make valve block cutting soil under the spring force effect during soil sampler lifting, traditional pull-type is avoided to lead
Cause the fracture and disturbance of weak soil.
After soil sample barrel is screwed off from casing, fixation is screwed with nut at the both ends screw thread of soil sample barrel immediately, is being transported
Influence of the vibrations to sample can be reduced in the process.Soil sample barrel is the structure of semi-open type, can directly take out sample, then by sample
Top removes one layer with lower part, leaves the high aliquot of original state degree.
It is simple in structure, it is easy to maintain.The utility model many places are fixed using thread connecting mode, are readily disassembled assembling
And cleaning.
