The soil sampler has the beneficial effects of simple structure, simple equipment operation, easiness for processing and manufacturing, convenience in carrying and successful soil insertion; the operation for digging the section of soil is eliminated; furthermore, undisturbed soil structures at different depths can be sampled at a time, and the original structure of the soil is not damaged; and the soil sampler is large in sampling amount.
Description
Technical field
The present invention relates to soil sampling and determination techniques field, relate in particular to a kind of soil sample barrel.
Background technology
At present, in soil sampling and determination techniques field, accurately and reliably whether soil test result, key issue can be scientifically described, most important is exactly to be the accuracy of sampling and the processing of sample, and the collecting work of pedotheque is crucial, the whether accurate mensuration of soil and the accuracy of result thereof of being directly connected to of sampling, and to conveniently get the deep layer undisturbed soil that approaches natural structure, key is to use comparatively advanced soil soil sample barrel.
China is one of country that desertification is serious, and relevant findings of the survey show: 262.37 ten thousand square kilometres of national Desertification Soil areas, 173.11 ten thousand square kilometres of sandy land areas, account for respectively 27.33% and 18.03% of territory total area.Field sampling work is more, most of field sampling is all had inconvenient traffic, trudge, this just requires our soil sample barrel to sample accurately, simultaneously easy to carry, is convenient to installation and removal, reduce the needs of resource to external world as far as possible, such as needs electricity consumption or by water-driven etc., very inconvenience of field water detection, power taking is particularly more difficult in sand field sampling.
And soil sample barrel in existing technology all exists certain problem, for example the soil sample barrel in patent documentation CN102879222A just exists secondary to deposit, and can not get the problem of undisturbed soil; And soil sample barrel in patent documentation CN103389226A is steel nail during floor is hammered into soil by pricker hole, soil sample barrel is fixed on to earth's surface, when stopple coupon being pressed in soil by the downward acting force of handle when fetching earth, reacting force is easy to steel nail to extract ground, can affect the accuracy of the degree of depth that fetches earth; And soil sample barrel in patent documentation CN103063467 not mentioned layering and undisturbed soil such as deposit at the problem too, once only can get the undisturbed soil of a degree of depth, more fetching earth of deep layer needs to change the pipe that fetches earth, and may cause the former position veneer of soil that fetches earth to cave in, and levels soil mixes; Meanwhile, the structure relative complex of the soil sample barrel in above three patent documentations, to operating personnel technical require high.
Summary of the invention
The object of this invention is to provide a kind of soil sample barrel, to overcome current soil sample barrel, once only obtaining a kind of deficiency of undisturbed soil of the degree of depth.
