Technical field
The utility model is related to soil sampling fields, more particularly to a kind of soil sampling anti-cross-contamination control panel.
Background technology
In the natural environment, when acquiring the pedotheque of designated depth using the drill bit that fetches earth, the sample production between different depth
The risk of raw cross contamination is higher, and especially below ground second layer pedotheque is easiest to be sampled the surface soil on hole periphery
Pollution (i.e. surface soil falls into sampling hole and generates pollution).It is dirty in order to avoid intersecting when acquiring designated depth pedotheque
Dye, generally by fetching earth drill bit and realizing for lengthening is used, the drill bit that will disposably fetch earth first is drilled into specified existing technology
Depth of soil, drill bit is extracted from soil then, is taken out after the soil in drill bit is finally divided into multistage, different depths are obtained
The pedotheque of degree.Method in the prior art has the following disadvantages：(1) use is fetched earth drill bit acquisition pedotheque, general to bore
Head in earth pillar length have it is a degree of compressed, compression degree is related with the quality of adopted soil and water content, fetches earth
Drill bit longer its earth pillar compression it is more severe, the drill bit of lengthening can significantly increase compression, after the earth pillar in drill bit is compressed,
It is difficult the relationship for determining earth pillar length and actual grade, it is not necessarily designated depth to lead to the sample obtained, more hole samplings
Collimation also is difficult to ensure；(2) length of the conventional drill bit that fetches earth is generally 10-20cm, and the drill bit that fetches earth of lengthening is all to need spy
System, and drill bit can be also limited with increased length, therefore, it is difficult to meet the requirements the deeper sample requirement of sampling depth；
(3) drill bit that fetches earth of lengthening is drilled into specified depth of soil and one has more highly difficult operation.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of soil sampling anti-cross-contamination control panel so that accurate
The really pedotheque of acquisition designated depth, without the special drill bit that fetches earth, the depth of collecting soil sample is not by the length for the drill bit that fetches earth
Degree limitation.
To achieve the above object, the utility model provides following scheme：
The utility model provides a kind of soil sampling anti-cross-contamination control panel, including tablet and column tube, the cylindricality
Pipe is hollow-core construction, and through-hole is provided on the tablet, and the column tube is set to below the tablet, the column tube and institute
Through-hole is stated to communicate.
Further, the through-hole is set to the plate center.
Further, the through-hole both sides are symmetrical arranged there are two mounting hole.
Further, the other both sides of the through-hole are symmetrical arranged there are two portable draw ring.
Further, the column tube is cylindrical tube.
Further, the through-hole is circular hole.
Further, the cylinder bore is identical as the Circularhole diameter.
Further, the tablet forms the control panel of integral structure with the column tube.
Further, the column tube is fixedly connected with the tablet.
The utility model achieves following technique effect compared with the existing technology：
1) the soil sampling anti-cross-contamination control panel of the utility model, easy to use, easy to operate, upper layer of soil sample
After acquisition, control panel is put into sampling hole, avoids the soil fallen by upper layer of soil sampling hole periphery when acquisition lower soil
Pollution, thus achieve the purpose that anti-cross-contamination, due to using segmentation directly acquire designated depth soil, the sample of acquisition and
The matching for planning sampling depth is very high, accurately collects the pedotheque of designated depth, ensures the parallel of more hole samplings
Property.
2) the soil sampling anti-cross-contamination control panel of the utility model is versatile, can reduce sampling cost, soil-like
The depth of product acquisition is not necessarily to the special drill bit that fetches earth not by the length limitation for the drill bit that fetches earth, and can be reached using conventional bit and be kept away
Exempt from the effect of pedotheque cross contamination.

A little attached drawings obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model soil sampling anti-cross-contamination control panel.
Reference sign：1, tablet；2, column tube；3, through-hole；4, mounting hole；5, portable draw ring.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings and have
Body embodiment is described in further detail the utility model.
As shown in Figure 1, the present embodiment provides a kind of soil sampling anti-cross-contamination control panel, including tablet 1 and column tube
2, column tube 2 is hollow-core construction, and through-hole 3 is provided on tablet 1, and column tube 2 is set to 1 lower section of tablet, column tube 2 and through-hole 3
It communicates.
Through-hole 3 is set to 1 center of tablet, and for the ease of control panel is fixed, two are symmetrical arranged in 3 both sides of through-hole
Mounting hole 4.For the ease of taking and placing control panel, two portable draw rings 5 are symmetrical arranged in the other both sides of through-hole 3.
In this specific embodiment, column tube 2 is cylindrical tube, and through-hole 3 is circular hole, cylinder bore and Circularhole diameter phase
Together, tablet 1 forms the control panel of integral structure with column tube 2.In another implementation, column tube 2 is fixedly connected with tablet 1,
Column tube 2 forms detachable split structure with tablet 1.
Cylinder length of tube is identical as the depth of first layer pedotheque of plan acquisition in the present embodiment, the outer diameter of cylindrical tube
Less than the internal diameter of the drill bit that fetches earth used in acquisition first layer pedotheque, the internal diameter of cylindrical tube is more than the acquisition second layer and following soil
The outer diameter of the drill bit that fetches earth used in earth sample.
The present embodiment also provides a kind of method of sampling using soil sampling anti-cross-contamination control panel, including following step
Suddenly：
1) it is first sampled using the drill bit that fetches earth of acquisition first layer pedotheque；
2) it and then by soil sampling anti-cross-contamination control panel is put into the middle position in sampling hole, is inserted into ground in mounting hole
The soil sampling anti-cross-contamination control panel is fixed in nail；
