Abstract
The present invention discloses a kind of soil layered sampler, including cylindric sampling cavity, the lower end of sampling cavity are provided with sample tap, and the upper end of sampling cavity is provided with nesting port, and the sample tap extends downwardly out the bootstrap block of a del；The sampling cavity side is provided with that an insertion sampling cavity is inside and outside, bar hole along sampling cavity axial direction.Sampler is inserted in soil, sample enters sampling cavity from sample tap, and fills up sampling cavity.After the completion of sampling, extruded from sample tap to nesting port, sample can discharge from nesting port complete, well arrangedly.
Description
Technical field
The present invention relates to a kind of soil sample collector, and in particular to soil layered sampler.
Background technology
In agriculture and forestry production, it is often necessary to the soil regime of planting site is monitored, to adjust crop in time
Planting conditions.The instruments such as the typically logical scoop of existing soil sample directly take soil, and the sample level obtained mixes, it is impossible to
Accurate nutrition, the insect pest situation for testing out soil layer.The sampler of existing a kind of tubular, by the way that tube shape metal piece is inserted in soil
Extract again, obtain well-bedded pedotheque.But this kind of sampler only has front opening, it is difficult to by sample it is complete, do not crush
Take out on ground.And there is no grasp force to soil, it is difficult to sample intactly from soil body separation, taking-up.
The content of the invention
In view of this, the present invention provides a kind of sampler that can extract stratified soil sample.
The purpose of the present invention is realized by following technology：A kind of soil layered sampler, including cylindric sampling cavity, take
The lower end of sample chamber is provided with sample tap, and the upper end of sampling cavity is provided with nesting port, and the sample tap extends downwardly out a del
Bootstrap block；The sampling cavity side is provided with that an insertion sampling cavity is inside and outside, bar hole along sampling cavity axial direction.
The operation principle of the present invention is as follows：Sampler is inserted in soil, sample enters sampling cavity from sample tap, and fills up
Sampling cavity.After the completion of sampling, extruded from sample tap to nesting port, sample can discharge from nesting port complete, well arrangedly.This
Outside, the present invention sets the bootstrap block of del also especially at sample tap, can not only reduce the resistance that sampling cavity enters soil
Power, being extracted when sampler makes, and can also increase its contact area with sample, increase and the resistance of sample, avoids sample disintegration, falls
Fall.Bar hole is then easy to observe the sample situation in sampling cavity under conditions of sample is not taken out.In addition, after the completion of sampling, also
Small spoon can be inserted into sampling cavity from bar hole, to take out the sample of specific level.
Further, it is convex along it to be axially arranged with multiple annular detentions concentric with sampling cavity for the inwall of the sampling cavity
Platform；Described its cross section of detention boss is right angled triangle, and one of right-angle side is affixed with sampling cavity wall, another right angle
While towards nesting port.
The present invention sets detention boss especially in sampling cavity, and extracting soil in sampler makes, and detention boss can be to taking
The sample of sample intracavitary provides larger crawl, support force, to keep taking out the integrity degree of sample.And detention boss also makes sampling cavity
Interior local constriction, pressure of the sampling cavity wall to sample radially is added, helps further to support sample.Detention boss can
To be integrally formed by metal working process and sampling cavity.
Further, described its top surface of detention boss is provided with multiple annular grooves concentric with sampling cavity.
Annular groove can further increase the contact area of detention boss and sample, crawl of the lifting sampling cavity to sample
Power.
Preferably, in addition to top cover, top cover include grip part of the radius more than the column of sampling cavity inside radius and by holding
Choking portion that the portion bottom surface of holding is extended, with the isometrical matching of nesting port；Choking portion is filled in the nesting port；The bar hole
Bottom opening, sealing strip is installed in bar hole；The side of sealing strip is provided with sealed groove, the edge wedging institute of the bar hole
State in sealed groove.
After sample is full of sampling cavity, top cover is filled in, the condition that negative pressure is produced in sampling cavity can be made, with pipette samples, carried
Height, which extracts sampling cavity, makes the in stable condition degree of sample.After the completion of sampling, sealing strip can be slided out of bar hole, taken out.
Preferably, the scale area of indicated depth is provided with the outside of the bar hole.
