Preferably, the first end of the shell is arranged to tip ends.
Preferably, the first end of the shell has the gradually smaller region of internal diameter of the second end relative to shell.
Preferably, the side opening is arranged to extend to the second end of shell, and the side from the first end of shell
Opening is disposed through the first end of the shell.
Preferably, the handle mechanism includes flexible handle, the partition being connected with flexible handle and will be described
The connecting rod that flexible handle is connected with partition, the connecting rod are arranged in the interior of shell by the second end of the shell
In portion space, and the partition is set in the inner space of shell.
Preferably, the bottom sampler further includes supporting mechanism, the supporting mechanism includes fixed handle and sleeve, institute
The one end for the sleeve stated is connected with the fixed handle, the second end phase of the other end of the sleeve and the shell
Connection, and the connecting rod is arranged in the sleeve.
Preferably, the side opening is oblong openings.
Using the bottom sampler for intertidal zone zoobenthos of the utility model, in the bed mud of different niches, bottom is acquired
It dwells sample, it is not only time saving and energy saving, reduce error, and preferably protect the external structure of zoobenthos.

Specific embodiment
In order to more clearly describe the technology contents of the utility model, come combined with specific embodiments below further
Description.
It is a kind of bottom sampler for intertidal zone zoobenthos provided by the utility model, wherein institute as shown in Fig. 1~2
The bottom sampler stated include there is shell 2 adopt mud cylinder 1, the shell includes first end 3, second end 4 and positioned at described
Inner space 5 between first end and second end, the first end are open end, and the second end is connected with handle mechanism
It connects, the shell is provided with axially distributed side opening 6.
Wherein, adopting mud cylinder can be set into the cylinder of an interior hollow cross-section diameter 10cm, side length 20cm.Upper end with
Main shaft is connected, and there is hole in upper-center part, and interlocking lever is allowed to pass through, and there is tip gap in lower end.Side opening is preferably set to one
Oblong openings, diameter of section 2cm, side length 17cm.
It can be by seeing adopting in mud cylinder whether be full of by soil at side opening, if needing to resurvey there are gap
Soil sample, it is ensured that the accuracy of experiment；Soil in certain habitats is really up to the mark, can make soil pressure by external force by opening
Out.
In a kind of preferably embodiment, the first end of the shell is arranged to tip ends.First end is gap
Tip is polished herein, and leading edge is ellipticity.Because in certain habitats, if reed belt, scirpus triqueter band, Spartina alterniflora are in soil
There are many rhizome, tip polishing reduces forced area, increases pressure, cut off the plant roots and stems of surrounding, and pushing when conveniently adopting mud makes
Bottom sampler enters depth of soils, can take out complete soil sample.
In a kind of preferably embodiment, the first end of the shell has the internal diameter of the second end relative to shell
Gradually smaller region.
In a kind of preferably embodiment, the side opening is arranged to extend to the of shell from the first end of shell
Two ends, and the side opening is disposed through the first end of the shell.
In a kind of preferably embodiment, the handle mechanism includes flexible handle 7, is connected with flexible handle
Partition 8 and the connecting rod 9 that the flexible handle is connected with partition, the connecting rod pass through the shell the
Two ends are arranged in the inner space of shell, and the partition is set in the inner space of shell.
Wherein, flexible handle can be set to solid column irony construction, and long 14.5cm, cylindrical cross-section diameter 1cm are living
The center of fixed handle is detachably connected or is welded to connect with connecting rod；Connecting rod can be set to the stick-like knot that solid-iron texture is made
Structure connects pole length 90cm；Partition diameter is slightly smaller than the interior hollow cross-section diameter for adopting mud cylinder, can be set to 8cm, makes it can
It is slided up and down adopting in mud barrel structure, the upper end is connected with connecting rod, convenient for extruding soil from bottom sampler.
In a kind of preferably embodiment, the bottom sampler further includes supporting mechanism, and the supporting mechanism includes
Fixed handle 10 and sleeve 11, one end of the sleeve are connected with the fixed handle, the other end of the sleeve
It is connected with the second end of the shell, and the connecting rod is arranged in the sleeve.
Wherein, the length of fixed handle can be set to 30cm, the solid stick-like structure of irony quality, diameter of section 2.5cm,
There is a hole in the center of handle, connecting rod is allowed to pass through；The length of sleeve can be set to the open column shape irony construction of 70cm,
Cross-sectional internal hollow diameters 2cm, diameter of section 4cm.
It is first that floor vegetation is clear when acquiring the soil sample of different niches when using the bottom sampler of the utility model
Reason is clean, chooses a small pieces vacant lot, is drawn the partition of connecting rod connection to top layer using flexible handle, by pressing fixed hand
Handle slowly rotates bottom sampler, and tip is made to enter soil soil layer, if soil is too hard, makes it into deeper depth using external force,
After to required experiment depth, loosen the soil sample around bottom sampler by rotating fixed handle, then inclination is extracted, by pressing
Flexible handle is pressed, partition is pushed to release soil from adopting in mud cylinder.If, can be by rectangular when the bad extrusion really up to the mark of soil sample
Soil is forced out by external force at shape side opening.
Using the bottom sampler for intertidal zone zoobenthos of the utility model, in the bed mud of different niches, bottom is acquired
It dwells sample, it is not only time saving and energy saving, reduce error, and preferably protect the external structure of zoobenthos.
In this description, the utility model is described with reference to its specific embodiment.But it is clear that still may be used
With the spirit and scope that various modification can be adapted and converts without departing from the utility model.Therefore, the description and the appended drawings should be considered
It is illustrative and be not restrictive.
