Embodiment
Structure of the present utility model is carried out below in conjunction with the accompanying drawings explanation is explained in detail.
As shown in Figure 1, the utility model provides a kind of soil eluviation liquid sampler, and the device includes being integrally formed
Inner cylinder 1 and outer barrel 2, be disposed with earth pillar rest area 3, filter mesh layer 4, quartz sand layer 5, Multi-hole steel from top to bottom in inner cylinder 1
Plate 6, funnel 7, receiving flask 8, are inserted with probe tube 9 in receiving flask 8, and the other end of probe tube 9 is through the sky between inner cylinder 1 and outer barrel 2
Gap is connected with negative pressure pump 10 and liquid sampling bottle 11.
The utility model earth pillar rest area 3 is used to place earth pillar soil, under conditions of rainwater or irrigation, the leaching in soil
Molten thing migrates downward into through root system, and by the filtering of filtering meshes 4 and quartz sand layer 5, leaching liquor passes through stephanoporate steel plate 6, funnel
7 enter in receiving flask 8, extract leaching liquor into liquid sampling bottle 11 from receiving flask 8 using negative pressure sampling apparatus, Multi-hole steel
Plate 6 mainly plays a supportive role, and the setting of funnel 7 causes soil eluviation liquid completely into receiving flask 8.
Soil eluviation liquid sampler of the present utility model connects root soil when in use, by periphery vegetation and dug out, and places
Aside, then successively excavate to 30cm, be fitted into after earth pillar is taken out in earth pillar rest area 3, soil eluviation liquid sampler buries
