The rubber ring of rubber pad, the feed liquor guard for sampling bottom of the tube are provided with sealing ring around pumping rod circumference, with upward in liquid
Entered in sampling pipe by negative pressure in liquid when pull pumping rod, pumping rod bottom end is provided with enters sampling pipe for limiting the end
The limited block of inner cavity.
Preferably, the filter opening diameter of the feed liquor guard is not less than 3mm.
Preferably, the pumping rod is located on the body of rod in sampling pipe and pumping rod is located at sampling pipe top or more
The body of rod on be wrapped with rubber pad, directly recline sealing between the pumping rod bottom body of rod and sealing ring, so that rubber pad is always
On the upside of feed liquor guard.
Preferably, the pumping rod top is pierced by the top of sampling pipe is provided with a lifting plate after sealed end, it is described to carry
Trepanning is offered on pulling plate.
Compared with prior art, the utility model has the advantages that：
Sampler described in the utility model, it is simple in structure, on the one hand, the rubber pad set convenient for sealing is wrapped up on pumping rod,
It coordinates the rubber ring and gasket on sampling pipe top and bottom end, forms elastic packing between pumping rod and connect, sealing effect
Fruit is good, and when below sampling pipe bottom end merging liquid level, the feed liquor guard of bottom forms fluid-tight, and pull pumping rod can adopted at this time
Negative pressure is formed in sample pipe, and then liquid is made to enter in sampling pipe, on the other hand, by feed liquor guard when liquid enters sampling pipe,
It can prevent large granular impurity in liquid from entering in sampling pipe, avoid doping bulky grain miscellaneous in the case where not influencing sample liquid
Matter avoids damaging sampling pipe.
Description of the drawings
