The sampling apparatus for root soil solution of shape.
Utility model content
The purpose of this utility model is the deficiency for existing soil liquid sampling apparatus, provides a kind of length and changes just
Victory is suitable for different sampling occasions, and sampling head intensity is high, the on-deformable sampling apparatus for root soil solution.
The utility model provides following technical solution:
A kind of sampling apparatus for root soil solution including connected sampling mechanism and extends mechanism, the sampling
Mechanism includes sampling tube body, the sampling head set on described sampling tube body one end and the connector set on the sampling tube body other end,
Several support columns are equipped in the sampling head, be equipped in the connector first through hole for accommodating the sampling tube body and with it is described
The cavity that first through hole is connected；The mechanism that extends includes extending tube body, set on the transit joint for extending tube body one end
With the connector for being set to the extension tube body other end, the transit joint is interior to be equipped with perforative second through-hole, the sampling tube body
End be inserted into second through-hole.
Preferably, the connector is equipped with the plunger hole with the first through hole vertical connection, is equipped with column in the plunger hole
Plug, plunger is filled in, and can be played the role of pressure to sampling tube body or extension tube body, be prevented its dislocation；Plunger is extracted, it is changeable to take
Sample tube body and the length for extending tube body stretching connector.
Preferably, the plunger top is connected with drawstring, and the drawstring is connected with fixed block, and the fixed block connects with described
Head is an integral molding structure, and is lost after preventing plunger from extracting.
Preferably, the outer surface of the sampling head is equipped with anti-skid chequer, improves the frictional force between sampling head and root soil, prevents
Only sampling head falls off from root soil.
Preferably, the connector is equipped with sealing column close to one end of the first through hole, and the leakproofness of connector can be improved.
The beneficial effects of the utility model are:
(1) it is equipped with several support columns in the sampling head of the utility model, the intensity of sampling head can be enhanced, prevent sampling head
It is bent when insertion root soil or culture medium, is conducive to the service life for smoothly sampling and extending sampling head.
(2) the utility model is equipped with sampling mechanism and extends mechanism, and when short distance sampling, can be used alone sampler
Syringe is connected to connector and is sampled by structure；When long range samples, the end of probe tube can be inserted into transit joint, be made
It is sampled with sampling mechanism plus several forms for extending mechanism, therefore is suitable for different sampling occasions.
