Above-mentioned a kind of undisturbed soil sampler, it is characterized in that: described gear force transmission shaft is designed to the gear bar coincide with the tooth sector of above-mentioned force application part, gear force transmission shaft lower end is designed to the cylindrical sleeve equal with hollow bushing inside diameter, produces rock for preventing gear force transmission shaft in active procedure.
Above-mentioned a kind of undisturbed soil sampler, is characterized in that: described thin-wall sampler is cylindric, and its bottom is offered as cutting edge shape, when sampling, first lubricant being applied in soil sample barrel cutting edge and inwall, guaranteeing that in sampling process, soil sample barrel within keeps comparatively slight drag.
The utility model compared with prior art has the following advantages:
1, simple, the reasonable in design and processing and fabricating of the sampling equipment structure adopted and easy accessibility, light small and exquisite, technique are simple and easy to produce.
2, the bottom sampling a kind of undisturbed soil sampler used is blade-like, and sampling mode fast and flexible, degree of stability are high.
3, when the soil body is steadily pushed sample aluminium box from soil sample barrel, perturbation is little, work efficiency is high, soil sample is by force representative.
In sum, the utility model discloses that a kind of structure is simple, processing and fabricating and easy accessibility, use is easy to operate and result of use good, test result accurately, easyly can realize cutting of undisturbed soil sample, and the soil body steadily can be pushed the device of sample aluminium box from soil sample barrel.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
