Embodiment
For a better understanding of the present invention, embodiments of the present invention are explained in detail below in conjunction with the accompanying drawings.
As shown in accompanying drawing 1 to accompanying drawing 3, including sampling cabinet and at least two sample bottles 8, multiple sample bottles 8 can avoid because
Sample bottle 8 occurs pollution and can not prepare detection, and sampling cabinet includes case lid 1 and casing 2, and case lid 1 is connected with casing 2 by pulling buckle 3
Connect (pulling buckle be existing matured product, be no longer described in detail herein), and handle 11 be provided with the upper end of case lid 1, facilitate it is portable, turn
Move, at least two fixes sleeves 4 corresponding with sample bottle 8 are provided with the bottom side of casing 2, the material of fixes sleeve 4 is iron, and
In inner side provided with heat conductive rubber layer, sample bottle 8, which is placed in fixes sleeve 4, can avoid because being rocked in carry process and fixed cover
The friction of cylinder 4 is excessive to cause bottle damaged, is provided with division board 5 in the bottom middle position of casing 2, and be provided with backman in opposite side
Has case 6, each fixes sleeve 4 is highly both less than the height of sample bottle 8, facilitates taking for sample bottle 8.
In order to carry out cooling processing to sample, ice cube can be placed around fixes sleeve 4, it is in no ice cube or not square
Just in the case of increase weight, it can be cooled in the following manner：
The refrigerator pipes 7 being distributed around fixes sleeve 4 provided with curl, refrigerator pipes 7 pass through connecting tube and on-board air conditioner
The port of export be connected, the inlet end 71 of refrigerator pipes 7 is located at the lower end of sampling cabinet side wall, and outlet side is located in fixes sleeve 4
At side position, cold air is top-down to cool to sample cell, and in order to improve cooling-down effect, refrigerator pipes 7 are entirely around institute
There is the spiral of fixes sleeve 4 upwards, the application of air-conditioning cold air or refrigerator cold air is very easy to sample and cooled this mistake
Journey, solve traditional ice block cooling also need to pour out in the water of thawing, the unabiding problem of cooling-down effect.
Provided with package seal checker, self-stick notes, sampling registration form and strip of paper used for sealing in auxiliary tool box 6, by sample collection when institute
Need instrument all to put together, add flexibility, after the completion of sample collection, pass through the important information marks such as self-stick notes progress time
Note and be attached to the outside of 8 place fixes sleeve of sample bottle 4, reduce and be attached to the problem of influenceing observation on sample bottle 8.
Each sample bottle 8 is tubbiness vial, and glass is good by property, convenient observation, and is not reacted with milk,
Will not contaminated samples, be designed with each upper end of sample bottle 8 for milk sample entrance/outflow probe tube 81 and sealing detection
Device, in order to avoid because milk storage tank exit is contaminated and caused by the contaminated problem of sample, be provided with probe tube 81
Three-way connection 83, milk collector of the end of three-way connection 83 3 respectively with milk storage tank, sample bottle 8 and producer is corresponding, and three
Pass joint 83 is provided with the first valve 84, by the control to the first valve 84, realizes to the time being sampled and sample position
The control put.
Package seal checker includes surge pipe 821 and piston 822, when gathering sample, can play adjustment sample
The effect of intraductal atmospheric pressure.When collecting sample, milk storage pressure inside the tank is big, can be compressed the air in sample bottle 8, enter
And piston 822 is increased, and collection work is smoothed out, scale is marked with the lateral wall of surge pipe 821, it is convenient to sample
Sample volume is positioned in bottle 8, in order to which the air-tightness to surge pipe 821 is detected, package seal checker also includes inflating
Cylinder, the outlet side of inflator is engaged with the upper end of surge pipe 821, before collection sample, is beaten by inflator into sample bottle 8
Press, and inflator is not pulled down, and is marked the now corresponding scale of piston 822, is observed the position of piston 822, two after a period of time again
Individual scale compares, and judges whether surge pipe 821 leaks.
In order to avoid the chronic leak that piston 822 may occur, the second valve 85, second are additionally provided with surge pipe 821
Valve 85 is located at the downside of piston 822, plays a part of auxiliary and keeps sealing.
In order to whole equipment carry out air-leakage test, package seal checker also include air-tightness leak detector, first pass through by
The pressure in the increase sample bottle 8 of piston 822 is pressed, promoting the circulation of qi is then entered to probe tube 81 and surge pipe 821 by air-tightness leak detector
Close detection, increases detection range, it is ensured that the accuracy of milk quality testing.
The course of work of the present invention：First equipment is integrally sterilized, after milk storage tank interface end opens a period of time,
The first valve 84 and the second valve 85 are opened, fresh milk sample is flowed into sample bottle 8, sample capacity is observed by scale,
Reach and the first valve 84 is closed after scheduled volume, complete sample collection.The corresponding scale of piston 822 is recorded, observes and carves after a period of time
Whether degree changes, and such as scale changes, then this bottle of sample has polluted, it is impossible to carry out quality testing.Ensure to the full extent
The freshness of sample.
Although above-mentioned the embodiment of invention is described with reference to accompanying drawing, not to the scope of the present invention
Limitation, on the basis of technical scheme, those skilled in the art need not pay creative work and can make
