Abstract

The invention provides a standard sample divider. The standard sample divider comprises a shell (100), a funnel (101), at least three sample division rings (121), a first sample receiving hopper (300) and a second sample receiving hopper (400), wherein the bottom of the shell is connected with the ground through a support, the funnel is located on the top of the shell (100), and the sample division rings are located on the lower portion of the funnel (101). Samples are mixed once by means of the three sample division rings sequentially arranged on the standard sample divider from top to bottom, and then the mixed samples are equally divided into two parts by means of a through hole in the sample division ring on the lowest side and a drainage plate beside the through hole, so that components and the number of the samples in the first sample receiving hopper and the second sample receiving hopper are basically consistent.

Description

Standard sample riffle sampler

Technical field

The present invention relates to a kind of experiment appliance, particularly relate to a kind of riffle sampler dividing sample for sample.

Background technology

When quality restriction is carried out to grains, oil plant, in addition to skewer takes a number of representative sample, right Whether sample is carried out is sufficiently mixed, uniformly, division goes out required representative test sample, is affect one that grain oil plant detects Key factor.Standard sample riffle sampler is exactly that the grains oil plant sample taking skewer carries out being sufficiently mixed uniform point and goes bail for and stay Sample, testing sample, the instrument of sample survey.

In riffle sampler method in GB5491-85 grain, oil plant inspection sample, point sample method, need with riffle sampler will in, granule Raw grain and oil plant divide sample.That is, from sack sample, division goes out two or more same sample and tests, and whether tests it Qualified, preferably deposit and processing quality etc..

For ensure sampling uniformly need the sample selected is carried out being sufficiently mixed and sole, every with ensure to be separated out The physical characteristic of part sample and chemical characteristic are close.It is divided into two parts accordingly, it would be desirable to be sufficiently mixed with riffle sampler again.

Riffle sampler is by funnel, point sample lattice and connects the parts such as sample bucket and forms.When dividing sample, the riffle sampler of cleaning is put surely, close Funnel switch, puts well and connects sample bucket, pours in funnel by sample, strikes off sample, open funnel and open at higher than bell mouth about 5cm Close, after sample flows to end, pat riffle sampler shell, close funnel switch, then two samples connecing in sample bucket are poured into leakage simultaneously In bucket, continue to repeat to mix twice according to upper method.

Thus by funnel twice and connect the cooperation of sample bucket by sample mix twice, and third time mix after can directly by The sample that two connect in sample bucket takes out, and is used for testing.

But, traditional riffle sampler needs to repeat aforesaid operations, causes point sample efficiency low, and experiment is time-consuming long, and sample is easy Lose.Therefore, a kind of point of sample efficiency height, protection sample integrity, the uniformity improving divided sample and representativeness are needed at present badly Riffle sampler.
