On the other hand, because the clean level of soil sample to equipment is less demanding, piston is therefore adopted to be released by soil proper.If but the sampling of cheese still adopts piston that sample is released cylindrical shell, then the gap location that piston coordinates with cylindrical shell is easily sheltered evil people and countenance evil practices breed bacteria, and is unfavorable for very much cleaning.
Summary of the invention
The technical problem to be solved in the present invention is unfavorable clean, the complex structure of the sampling equipment in order to overcome prior art and the defect causing sampling precision low because of cheese crimp, provides a kind of not yielding, structure to be simply beneficial to clean easy cheese sampling equipment.
The present invention solves above-mentioned technical matters by following technical proposals:
A kind of easy cheese sampling equipment, its feature is, it includes at least two sampler barrels;
Described sampler barrel one end is the columnar neck of mono-disperse, described neck one end open, and the other end extends to form the cylindrical shell that a diameter becomes large flaring opening gradually;
The side of described cylindrical shell and the side of described neck are 165 ° ~ 175 ° angles;
Identical and the clearance fit of the shape of described cylindrical shell mutually nested.
Cheese, after entering sampler barrel, can continue the friction being subject to sampler barrel madial wall, and the cheese entering sampler barrel after in sampling process can be pressed tighter.If therefore a part for sampler barrel is arranged to diameter to become large tubaeform gradually, the cheese be introduced into less contacts the inwall of sampler barrel, then sampled cheese various piece can be more even, therefore can keep cylindrical shape but not circular platform type after disengaging sampler barrel.
In addition, during sampler barrel operation, by neck toward being pushed down in bulk cheese, then sampler barrel entirety is extracted, and then the neck of last sampler barrel is stretched into the neck of another sampler barrel, due to can mutually nested formation clearance fit between each sampler barrel, the cheese in the sampler barrel of large size can eject by therefore small size sampler barrel smoothly.
Preferably, the opening of described neck is extended the jagged cutting part of a circle.
That is, be provided with cutting part and be more conducive to sampler barrel sampling, if the resistance that vertical depression enters cheese is excessive, can rotate sampler barrel, such cutting part can cut cheese easily.
Preferably, the length of described neck is 5% ~ 40% of described sampler barrel total length.
Preferably, the length of described neck is 25% of described sampler barrel total length.
Herein, the ratio of neck length has certain being particular about, if neck accounts for overall length, ratio is excessive, then still likely occur that sampled cheese heterogeneity causes sampling the change of shape, if proportion is too small, then it is cylindrical that the cheese sampled also is difficult to formation.
Preferably, the periphery, one end of described cartridge openings is provided with flange.
Herein, owing to can arrange multiple sampler barrel, each sampler barrel can be stacking by flange when mutually nested, is more conducive to deposit.And when carrying out sampling operation, also need by hand on flange, can lifting surface area be increased, more convenient operation.
Preferably, the friction factor of the inwall of described cylindrical shell and described neck is less than 0.1.
Preferably, the friction factor of the inwall of described cylindrical shell and described neck is less than 0.05.
Positive progressive effect of the present invention is: smooth inwall reduces friction factor, and flaring cylindrical shell reduces frictional distance and friction force, thus reduces crimp; By arranging the mutually nested release sample of multiple sampler barrel, simultaneously sampler barrel self comprises flaring cylindrical shell and circle tube neck part, makes keep cheese homogeneous in sampling process and then ensure that sample precision, and structure more easy, be easier to clean.
