Description

A kind of grain inspection sampler

Technical field

This utility model belongs to grain instruments of inspection field, and in particular to a kind of grain inspection sampler.

Background technology

Grain inspection work is significant, just so-called state's Putting common first, and bread is the staff of life, and grain is that the people is most basic The means of livelihood, and grain inspection work is the important leverage of grain security, is all that grain is carried out in the form of inspecting sample by random samples at present Food inspection, using sample is obtained in sampling sharp-pointed tube insertion grain sack, the sample that existing sampling sharp-pointed tube is obtained all is proximate to the sample of insertion point This, it is representative not strong, and also sampling amount is less, it is difficult to and the quality of whole bag grain is verified, is easily sought loopholes by bad retailer, than Such as in the bottom subpackage grain in storage for years of sack, in the new grain of top subpackage of sack, there is hidden danger in grain security.

The content of the invention

The purpose of this utility model is to solve the problems referred to above that existing sampling sharp-pointed tube is present, there is provided a kind of grain inspection Test and use sampler, its technical scheme is as follows：

A kind of grain inspection sampler, it includes outer skewer pipe, interior skewer pipe and skewer core, and the lower end of outer skewer pipe is provided with cone Head, outer skewer pipe and interior skewer pipe upper end are open end, and the external diameter of interior skewer pipe is coincide with the internal diameter of outer skewer pipe, and interior skewer pipe is planted In outer skewer pipe, the length of interior skewer pipe is not less than the length of outer skewer pipe, and it is right to be provided with the side wall of outer skewer pipe and interior skewer pipe The notch answered, the width of rebate on outer skewer pipe and interior skewer pipe are respectively less than or equal to a quarter of itself girth, outer skewer pipe and interior Skewer pipe is rotated against and can be blocked mutual notch, is formed the space of closing, is respectively provided with the upper end of outer skewer pipe and interior skewer pipe There is a flanging, the flanging diameter of the flanging of outer skewer pipe upper end with diameter greater than interior skewer pipe upper end, in outer skewer pipe and interior skewer pipe A handle is respectively arranged with flanging, is convenient for rotating against；Skewer core is cylindrical, the diameter of skewer core and interior skewer pipe Internal diameter coincide, skewer core is plugged in interior skewer pipe, the length of the length of skewer core not less than interior skewer pipe, is arranged in the upper surface of skewer core The surfaces externally and internally for having handle, outer skewer pipe, interior skewer pipe and skewer core is smooth surface.

The beneficial effects of the utility model are：Sample position is uniform, and sample closer to the distance with insertion point or farther out can Obtain, it is representative strong, and also sampling amount is larger, is easy to verify the quality of whole bag grain, prevents grain security hidden danger；According to grain The height of bag selects the sampler being adapted using length, is inserted vertically into grain sack, and in insertion process, grain will not enter device It is interior, it is to avoid the sample for obtaining all is proximate to the sample of insertion point, first skewer core is extracted out after insertion, when extracting skewer core out in interior skewer pipe Negative pressure is formed, grain sample rapidly enters interior skewer pipe, then rotates against outer skewer pipe and interior skewer pipe, mutual notch is sealed It is stifled, then the interior skewer pipe of outer skewer pipe is extracted out simultaneously, in extraction in space of the sample in closing, so the sample size for obtaining It is larger.
