Simply, it is easy to use, it is easy to promote.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is described in detail below with reference to accompanying drawing：
As shown in Figure 1：
A kind of device of field measuring litter water-holding capacity, including the outer tube 1 of a upper end open lower end closed, the outer tube
1 outside bottom surface is provided with acupuncture part 2；The upper end of 1 inwall of the outer tube is fixedly connected with collection hyponome 3, the collection hyponome 3
Enlarging is upward；Water permeating board 4 is stamped in the enlarging of collection hyponome 3, the water permeating board 4 is provided with multiple water seepage holes 5, the infiltration
The side wall of outer tube 1 is divided into upper vertical plate 11 and lower riser 12 by plate 4；Open up near the position of upper limb on the top of 11 side wall of upper vertical plate
There are multiple anti-overflow holes 6, the anti-overflow hole 6 extends to 1 interior of outer tube, and extends downwardly along C-shaped, and the other end is by lower riser 12
Side wall pass and positioned at collection hyponome 3 lower section；1 side-wall outer side of the outer tube is also fixed with handle 7, in the handle 7
End is removably connected with dust-collecting bucket 8, and the second collection hyponome 9 is provided with the dust-collecting bucket 8, and described second collects hyponome 9
Enlarging is upward.
So, when in use, the device is positioned over the sylvan life for needing measurement, and underground is inserted by acupuncture part 2, improved
The stability of device, the litter are will fall off on water permeating board 4, accumulation over time, the litter fallen in outer tube 1 and sylvan life
The coverage density of the litter is consistent, more conforms to the technical specification of in site measurement；When rainy, rainwater falls
In the litter on water plate 4, and flowed in collection hyponome 3 by water seepage hole 5, and then flowed in outer tube 1, during this, part
Moisture is cut by the litter and holds and preserve, when precipitation is excessive, as the infiltration rate of the litter is limited and reaches saturation shape
During state, for rainwater can be entered by the anti-overflow hole 6 on 1 side wall top of outer tube, the passage of Jing C-shapeds is flowed in outer tube 1, prevents outer
Water in precipitation area shared by cylinder 1 overflows to outside and affects accuracy of detection；As a comparison, it is also equipped with catchmenting on the outside of outer tube
Bucket 8, while rainwater is dropped in outer tube 1, identical unit rain also falls within dust-collecting bucket 8, by dust-collecting bucket 8 and outer tube 1
In liquid level contrast, you can draw the water-holding capacity of the litter；The setting of the second collection hyponome 9 can be very good to prevent moisture from steaming
Send out, improve accuracy of detection；And outer tube 1 and the handle 7 being connected of dust-collecting bucket 8, easily can be captured and be turned to the device
Move, it is convenient and practical.
The outer tube 1 is Square barrel or round tank.The section of rule can convenient unit of account area the litter water holding
Amount.
The outer tube 1 and dust-collecting bucket 8 are transparent material and make.Testing staff can be so facilitated to save bit by bit internal moisture
Degree and stopping state are observed, and are easy to safeguard.
Drainage screen is additionally provided with the water seepage hole 5, the upper surface of the drainage screen is concordant with the end face of water permeating board 4.Due to
Decomposition of leaf litter can produce many tiny residues after rotting, and it is frangible to soften, and drainage screen can be very good to prevent water seepage hole 5
It is blocked and has influence on water permeable ability.
The height of the upper vertical plate 11 is determined according to different regions maximum rainfall.Due to various places maximum precipitation difference,
If making upper vertical plate 11 too high, although water conservation preferably, but structure is not compact enough, also it is not necessary that, such improvement can
The height of upper vertical plate 11 is determined with according to the maximum rainfall in test area, rationally using anti-overflow hole 6, and reduce structure
Product, improves portability.
The water inlet in the anti-overflow hole 6 also is provided with drainage screen.Can so prevent anti-overflow hole 6 from blocking, affect to use.
The dust-collecting bucket 8 is threaded connection the end for being fixed on handle 7, and the axis of dust-collecting bucket 8 and handle 7 in bottom
Axis perpendicular.
The upper surface of the dust-collecting bucket 8 is concordant with the upper surface of outer tube 1.The drop of outer tube 1 and dust-collecting bucket 8 is can ensure that so
Water condition is consistent, reduces the oblique rainfall due to windage and the not high influence degree of caused certainty of measurement.
Scale is equipped with the side wall of the outer tube 1 and dust-collecting bucket 8.Testing staff is so facilitated to unite testing result
Meter record.
The beneficial effects of the utility model：By an outer tube that can be fixed on sylvan life and the dust-collecting bucket on outer tube,
And litter raking part is provided with outer tube so that rainwater part in descent is cut by the litter and is held, and part flows into outer
Cylinder is internal, then by the liquid level difference in matched dust-collecting bucket, you can the water-holding capacity of the litter is drawn, the apparatus structure
Simply, it is easy to use, it is easy to promote.
Above example is only unrestricted to illustrate the technical solution of the utility model, although with reference to preferred embodiment pair
This utility model has been described in detail, it will be understood by those within the art that, can be to technology of the present utility model
Scheme is modified or equivalent, and without deviating from the objective and scope of technical solutions of the utility model, which all should be covered
In the middle of right of the present utility model.
