Description
Technical field
The present invention relates to a kind of sampler, more specifically a kind of viscous samples for the rotten forms such as shape or semi-solid
Sample injector.
Technical background
When weighing the sample of the sticky character of meat gruel, puree etc., typically uses spoon and take sample and be added to weighing and hold
In device.But since such sample is more sticky, often it is sticked on spoon and causes to pick and place difficulty, repeated multiple times need to could weighs
To required quality, waste time very much.When needing to weigh a large amount of samples, this method has seriously affected working efficiency.
The present invention provides one kind can quick, accurate sample injector and loading methods method, can be used for various sticky samples
The weighing of product or quantitative sample-adding.
Invention content
The present invention aiming at the deficiencies in the prior art, provide it is a kind of and simple in structure, easy to operate, at low cost, fit
In the viscous samples sample injector and its application method of wide popularization and application.
The present invention is achieved by the following technical solutions：
A kind of viscous samples sample injector, including push-pull rod, piston, sample cylinder, feed head；The piston is arranged in sample cylinder,
The end of the push-pull rod is connect with piston, and the feed head is removably arranged in sample cylinder front end, the sample-adding cephalic par
Equipped with outlet.
Further, above-mentioned feed head by screw thread or is snapped connection with sample cylinder.
Further, the other end of above-mentioned push-pull rod is equipped with push handle.
Further, above-mentioned outlet is flat mouth or angle.
Further, above-mentioned outlet is connected with out sample tube.
As another goal of the invention of the present invention, the application method of above-mentioned a kind of viscous samples sample injector, including such as
Lower step：（1）Remove feed head；（2）Push-pull rod is pulled, piston is made to be moved to sample tube rear end；（3）Sample cylinder front end is inserted into
In sample, sample cylinder is extracted after sample enters sample cylinder；（4）Feed head is connect with sample cylinder, outlet is aligned and is weighed
Utensil, pushes push-pull rod, sample to inject in weighing container, stops pushing away when the registration of balance, which is shown to, weighs required quality
Pull rod, sample-adding are weighed and are finished.
Compared with prior art, the advantages and positive effects of the present invention are：Due to viscous samples enter will not after sample cylinder
Quickly outflow, therefore feed head is installed rapidly after extracting sample cylinder, should sample flow not be had in the process and gone out, can easily will very much
Sample is packed into cylinder, and sample is made uniformly to be squeezed out in outlet under stress, can in time be stopped when close to aim parameter is weighed；This
Invention can just make of any materials such as metal, plastics, glass as needed, can also be fabricated to disposable product, cost
It is cheap；It is used when sample weighings a large amount of present invention is particularly suitable for application in units such as testing agency, scientific research institutions, avoids sample
Pollution, substantially increases weighing efficiency.
