Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of device for the sampling of wetland soil, easy to carry, is easy to take out pedotheque and energy
The original state of soil is preserved very well, is improved working efficiency, can be acquired and store the pedotheque of different location different type wetland.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
As shown in Figs. 1-3, the present embodiment provides a kind of devices for the sampling of wetland soil, including sampler and sampling pipe
3, sampler includes sampler head cover 1, sampler cylinder 2 and capping 6, is from top to bottom provided with successively in sampler cylinder 2
Venting cavity 7, the capping of connection install room 8 and sampler inner cavity 9, and the through-hole being in communication with the outside is provided on 7 side wall of venting cavity
10, capping 6 is installed in capping installation room 8, passes through moving up and down in achievable venting cavity 7 and sampler for capping 6
Connection between chamber 9 or closing, sampler head cover 1 are fixed on the upper end of sampler cylinder 2, sampling pipe 3 and sampler cylinder 2
Lower end forms and is detachably connected.
As shown in Fig. 2, capping 6 includes conus portion 61, cylindrical portion 62 and the bottom plate 63 from top to bottom set gradually, circular cone
Portion 61 and cylindrical portion 62 are an integral structure, and are formed and are detachably connected between cylindrical portion 62 and bottom plate 63, capping is installed room 8 and wrapped
Include connection for limiting the conical cavity and the base plate chamber moved upwards for limiting bottom plate 63 that conus portion 61 moves downward, circular cone
Chamber is more than the diameter of cylindrical portion 62 with the diameter of the circular hole of base plate chamber junction.
In this specific embodiment, the inner wall of 7 upper end of venting cavity is provided with screw thread, and sampler head cover 1 is threadedly connected to logical
In air cavity 7.In another embodiment, sampler head cover 1 is sheathed in venting cavity 7, by trip bolt by the side wall of venting cavity 7
It is fixedly connected with sampler head cover 1.
For the ease of carrying out rotating down pressing to sampler when sampling, it is provided with handle 4 on sampler head cover 1, handle 4 is worn
Oversampler head cover 1 and 4 both ends of handle stretching sampler head cover 1.
Sampler cylinder 2 includes that from top to bottom sequentially connected first cylinder and the second cylinder, the outer diameter of the first cylinder are big
In the outer diameter of the second cylinder, the first cylinder and the second cylinder are an integral structure.
Further include hose clamp 5 in order to which sampling pipe 3 is fixed, hose clamp 5 is used to sampling pipe 3 being fixed on the second cylinder.
In order to enable intake process and exhaust process are more uniform, through-hole 10 is set as four and is uniformly distributed in venting cavity
On 7 side wall.
It is inserted into wetland and easily facilitates operator's use in order to be conducive to sampling pipe 3,3 bottom end of sampling pipe is circumferentially provided with more
A opening.
Specifically used process is：First sampler is assembled, capping 6 is installed in capping installation room 8, so
Sampler head cover 1 is fixedly connected with sampler cylinder 2 afterwards, then sampling pipe 3 is mounted on second of 2 lower end of sampler cylinder
External side is simultaneously fixed with hose clamp 5.
When sampling so that then sampler is pressed downward together by the lower end of sampler sampling pipe 3 and ground perpendicular contact
When along (or counterclockwise) direction rotating handles 4 clockwise, and then rotation is carried out to entire sampler and helps sampler quick
Reach desired depth.When needing to take out sampler outward, firmly handle 4, soil is slowly proposed by entire sampler, this
When due to negative pressure in sampler inner cavity 9 effect, sample 11 can be retained in inside the sampling pipe of lower end.
As shown in figure 4, when sampler is in the original state before sampling, capping 6 slides in conical cavity simultaneously naturally
By the circular hole closing between conical cavity and base plate chamber.As shown in figure 5, when arrow direction pushes sampler along figure,
Initial gas pressure inside and outside sampler inner cavity 9 is identical, and 9 chamber air of sampler inner cavity by lower part due to being come in sampling process
Sample 11 be pressed through open-top capping 6 and be discharged by the through-hole 10 of venting cavity 7.As shown in fig. 6, after stopping pushing, sampling
Air pressure inside and outside device inner cavity 9 restores consistent, and it is interior and by the circle between conical cavity and base plate chamber that capping 6 falls back to conical cavity naturally
It closes in hole.As shown in fig. 7, when arrow direction above carries sampler along figure, since sample 11 is under its gravity
Downwards slide certain distance, in the process in sampler inner cavity 9 volume of gas become larger so that sampler inner cavity 9 in pressure
Reduce, capping 6 is squeezed the circular hole closed between conical cavity and base plate chamber by atmospheric pressure, in 9 cavity of sampler inner cavity
Negative pressuren zone is formed, suction-operated is generated to sample 11 so that the sample 11 of lower part can smoothly take out.
It can be laid flat after entire sampler is proposed soil, in the flowing of the water on 11 surface layer of sample during being laid flat
Capping 6 is opened under percussion so that sampler inner cavity 9 is connected to venting cavity 7, by the water on surface layer by the through-hole of venting cavity 7
10 release.
Sampling pipe 3 and sampler cylinder 2 can be detached, and then sample 11 is handled, sample by unclamping hose clamp 5
11 directly can carry away the whole preservation of progress by closing 3 both ends of sampling pipe, can also as former state slowly fall it from sampling pipe 3
Go out to carry out in-situ treatment.It such as needs to carry out sampling work next time, it is only necessary to repeat another sampling pipe 3 being mounted on sampler
The lower end of cylinder 2 is used in combination hose clamp 5 to be fixed, and carries out sampling operation.
It can be seen that the device for the sampling of wetland soil of the present embodiment, achievable by moving up and down for capping 6
Connection between venting cavity 7 and sampler inner cavity 9 or closing, capping 6 moves upwards so that venting cavity 7 during sampling pushes
It is connected to sampler inner cavity 9 so that sample 11 is smoothly acquired, and when being lifted up sampler, sampler inner cavity 9 forms negative
Capping 6 is pressed in capping installation room 8 by pressure area, atmospheric pressure, and negative pressuren zone generates suction-operated to sample 11 so that sample
11 take out from underground intactly.The lower end of sampling pipe 3 and sampler cylinder 2, which is formed, to be detachably connected, different by replacing
The sampling pipe 3 of length can be acquired the sample 11 of different depth, by the way that interchangeable sampling pipe 3 is arranged, can improve
Working efficiency, the pedotheque of acquisition and storage different location different type wetland.
Specific case is applied in this specification, and principle and implementation of the present invention are described, above example
Explanation be merely used to help understand the present invention method and its core concept；Meanwhile for those of ordinary skill in the art,
According to the thought of the present invention, there will be changes in the specific implementation manner and application range.In conclusion in this specification
Appearance should not be construed as limiting the invention.
