Grassland soil infiltration appearance includes water supply part and water receiving part, its characterized in that: the water supply part by graduated flask, graduated flask scale, limbers, valve and panel board constitute, valve and limbers link to each other for water in the control graduated flask, have the panel board on the water supply parts, but the used time and the water yield in the precision measurement process of osmosis. The water receiving part is by detaining mouth, rubber seal, cutting ring and cutting ring scale, have in the cutting ring rubber seal, sealing performance is good, can prevent the edge leakage at the measurement process normal water, the cutting ring has outward the cutting ring scale can quantify the degree of depth that the soil body was implanted to the cutting ring. The water supply part with the water receiving part is connected with fixed through detaining mouth and rubber seal, forms grassland soil infiltration appearance. This infiltration appearance simple structure, the preparation of being convenient for, it is little to receive and keep area, is fit for field work, and accuracy of measurement is high.
Description
Technical field
The utility model relates to mensuration and the teaching aid field of soil permeability, particularly relates to a kind of grassland soil permeameter.
Background technology
Infiltration coefficient, also known as hydraulic conductivity, is the specific discharge under specific potential gradient in isotropic medium, represents the complexity of fluid by pore framework.The common method of current mensuration soil permeability coefficient is site test and experimental determination.The former need drop into a large amount of manpowers, equipment, and the process of mensuration is complicated, is unsuitable for large-area soil investigation.Soil sample is fetched laboratory to analyze by the latter, and due to destructible soil structures in sampling process, result is difficult to represent the actual perviousness of soil.
Utility model content
In order to solve the problems of the technologies described above or defect, the utility model provides a kind of grassland soil permeameter.This permeameter has the advantages such as volume is little, lightweight, simple to operate, easy to carry, cheap, can measure grassland soil infiltration coefficient exactly.
The purpose of this utility model is to provide a kind of grassland soil permeameter, comprises water supply component and water receiving parts, it is characterized in that:
Described water supply component is made up of graduated cylinder, cylinder scale, limbers, valve and panel board; Described water receiving parts are by detaining mouth, rubber seal, cutting ring and cutting ring scale;
Described water supply component is undertaken being connected with described water receiving parts by detaining mouth and rubber seal and fixes, and forms grassland soil permeameter.
Grassland soil permeameter as above, comprises further:
Described valve switch is connected with limbers, for controlling the water in graduated cylinder;
With panel board on described water supply component, can accurately measure the time used in process of osmosis.
Grassland soil permeameter as above, comprises further:
With described rubber seal in described cutting ring, favorable sealing property, can prevent the side leakage of water in measuring process;
Described cutting ring has described cutting ring scale in addition, can quantize the degree of depth that the soil body implanted by cutting ring.
The beneficial effects of the utility model are: this permeameter structure is simple, and be convenient to make, harvesting floor area is little, is applicable to field work.In use cutting ring is implanted the soil body, operation can be carried out in the domatic landform of difference, and water dispersing in meadow epidermis surrounding can be avoided.Adopt panel board to measure the water yield used and time in process of osmosis, can reduce the error of field trial reading, measuring accuracy is high.

Embodiment
Below in conjunction with drawings and Examples the utility model made and further illustrating.
In FIG, described water supply component is made up of described graduated cylinder 1, cylinder scale 2, limbers 3, valve 4 and panel board 5; Described valve 4 is connected with limbers 3, for controlling the water in graduated cylinder; With panel board 5 on described water supply component, can accurately measure time used in process of osmosis and the water yield.In fig. 2, described water receiving parts are formed by detaining mouth 6, rubber seal 7, cutting ring 8 and cutting ring scale 9; With described rubber seal 7 in described cutting ring 8, favorable sealing property, can prevent the side leakage of water in measuring process; Described cutting ring 8 has described cutting ring scale 9 in addition, can quantize the degree of depth that the soil body implanted by cutting ring.Described water supply component is undertaken being connected with described water receiving parts by detaining mouth 6 and rubber seal 7 and fixes, and forms grassland soil permeameter.
In specific implementation process, first the cutting ring 8 in water receiving parts is implanted meadow, the degree of depth of implantation is pressed shown in cutting ring scale 9.By button mouth 6, water supply component is connected with water receiving parts, due to the effect of rubber seal 7, can the side leakage of anti-sealing.After completing above-mentioned work, appropriate water is added in graduated cylinder 1, open valve 4, when water is full of cutting ring space, open panel board 5, start to record time used and the water yield.I.e. a kind of grassland soil permeameter.
Following improvement can also be made for above-mentioned a kind of grassland soil permeameter:
Panel board 5 can use electronics dial plate, thus can computing time clearly, may be used for the accurate measure water yield, directly draw the hydraulic conductivity in the unit interval after adding calculating system.
Cutting ring 8 knife face adopts level and smooth arc, can reduce friction, and is convenient to insert soil, and simultaneously knife face adopts tempered glass, the transparent materials such as organic glass, can so that whether experimenter's observation water fills up cutting ring 8, thus opens valve 4 and start timing.
It should be noted that: the only unrestricted the technical solution of the utility model in order to explanation above, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and do not depart from any modification or partial replacement of spirit and scope of the present utility model, all should be encompassed in the middle of right of the present utility model.
