The other side of the bottom sampler is set there are two connecting pin and a tie point, two connecting pins respectively with sampling
The two sides of bar are connected, the lower end connection of the tie point and thief rod；
The connecting pin is connecting plate, i.e., the two sides of thief rod pass through connecting plate respectively and the other side of bottom sampler is affixed,
The lower end of the thief rod and the other side of the bottom sampler are affixed；
The lower end of the thief rod is fixed in the upper surface of the bottom sampler other side, and the screen area and bottom sampler are another
The opening area of side is equal；Alternatively, the lower end of the thief rod is fixed in the lower surface of the bottom sampler other side, the sampling
The two sides of bar and another side opening intersection of the bottom sampler are equipped with sieve；
The end face of the bottom sampler is trapezoidal；
The upper end of the thief rod is convenient for hand-held arc；
The upper surface of the bottom sampler is parallel with lower surface, and maintains an equal level in sampling process with ground；
The thief rod and bottom sampler inclination connect.
The advantages of the utility model and good effect are as follows:
The utility model is applicable to intertidal zone by the way that telescopic thief rod, and the bottom sampler being used cooperatively is arranged
The acquisition of set depth and set amount surface sediment samples, operation letter are realized in surface deposit sampling location complicated and changeable
Single, sampling quality is high；It is easy to carry simultaneously, it is easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment one；
Fig. 2 is the structural schematic diagram of the utility model embodiment two；
Wherein: 1 is thief rod, and 2 be scalable latch closure, and 3 be connecting plate, and 4 be bottom sampler, and 5 be sieve, and 6 be tie point, 7
For injection port.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Embodiment one
As shown in Figure 1, the utility model includes thief rod 1, bottom sampler 4 and sieve 5, wherein bottom sampler 4 is inner hollow
Container, side be injection port 7, the other side is outlet, convenient for bottom sampler 4 inside water discharge, and outlet be equipped with sieve
Net 5.The bottom edge of injection port 7 extends outwardly compared with top margin, i.e., injection port 7 is inclined-plane, is from top to bottom inclined outwardly；The present embodiment is adopted
The end face of mud device 4 is trapezoidal, and the upper surface convenient for the acquisition of sediment sample, i.e. bottom sampler 4 is parallel with lower surface, injection port 7
It is two trapezoidal waists with outlet.Thief rod 1 is telescopic rod, and the thief rod 1 of the present embodiment is real by the way that scalable latch closure 2 is arranged
Now stretch, can transformed samples bar 1 as needed at any time length；The lower end of thief rod 1 is connected with the other side of bottom sampler 4, on
End is handheld terminal；For the ease of hand-held, carrying, camber is designed in the upper end of the present embodiment thief rod 1.Thief rod 1 and bottom sampler 4
