Abstract
The utility model relates to a simple soil water content indicator which comprises a cavity. The utility model is mainly characterized in that at least one surface of the cavity is a water permeation layer; the inner side of the water permeation layer is provided with a water-absorbing expansion layer; a telescopic film without water permeation is arranged at the inner side of the water-absorbing expansion layer; indicating liquid is filled in a liquid cavity of the inner side of the water-absorbing expansion layer; a graded tube is arranged on the cavity; the inner part of the graded tube is communicated with the liquid cavity, and the top end of the graded tube is provided with an air cavity. When the utility model is used, the water-absorbing expansion layer is expanded after the water-absorbing expansion layer absorbs the moisture in the soil; thus, the indicating liquid in the liquid cavity is pressed to enter the graded tube, and the water content of the soil can be known by the level display of the indicating liquid on the graded tube; thereby, the utility model is convenient for people to control the water content of the soil when the people plant or care plants, so the planting success rate and the care success rate are improved. The utility model has the advantages of small volume, portability, low cost and easy operation, and is suitable for agriculture planting, floriculture cultivation and care, etc.
Description
Technical field
The utility model relates to a kind of simple and easy soil moisture content indicating device.
Background technology
In the agricultural planting field, the required moisture of each kind of plant, the soil moisture in each soil plot all have bigger difference.Present most of people waters by rule of thumb, pours water, and the soil humidity is wayward, causes plantation, maintenance failure easily, especially when the maintenance of home flower, potted landscape, causes the situation of maintenance failure just often to take place because of the humidity of soil is unreasonable.Therefore, when plantation, maintenance, be necessary to grasp exactly the water cut situation of soil, people adopt some soil basis determining instrument to come the water cut of measured soil mostly at present, these instruments generally are to produce different induction currents by wet sensitive detection head under different humidity, by computer chip this current signal are converted into the different numerical value of soil moisture content then.These Instrument measuring precision height are applicable to agri-scientific research unit more, establishing in large scale etc., but its volume is big, complex structure, cost an arm and a leg, and carrying, use inconvenience, applicable surface is narrower.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides the simple and easy soil moisture content indicating device that a kind of volume is small and exquisite, easy to carry, operation is simple and easy, with low cost.
The purpose of this utility model realizes as follows: a kind of simple and easy soil moisture content indicating device, comprise cavity, the one side at least that is characterized in cavity is pervious bed, the pervious bed inboard is provided with the imbibition layer, imbibition layer inboard is provided with fluid-tight scalable film, dress indicator solution in the sap cavity of scalable film inboard, and cavity is provided with graduated tube, communicate with sap cavity in the graduated tube, the graduated tube top is provided with air cavity.
Graduated tube of the present utility model is provided with upper limit mark, lower limit mark.
Imbibition layer of the present utility model can adopt synthetic high polymer super absorbent resin or natural polymer super absorbent resin or super absorbent resin compound to make.
Pervious bed of the present utility model adopts porous structural material to make.
Because pervious bed has good permeable, conduction moisture characteristic, when the cavity with this device is embedded in the soil, the imbibition layer just can fully absorb the moisture in the soil, imbibition layer suction after expansion is pressed to the indicator solution in the sap cavity in the graduated tube, can understand the water cut situation of soil easily by the scale on the graduated tube.Compared with prior art, have advantages such as volume is small and exquisite, easy to carry, operation is simple and easy, with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cut-open view of Fig. 1.
Among the figure: 1 expression pervious bed; 2 expression cavitys; 3 expression lower limit marks; 4 expression graduated tubes; 5 expression scales; 6 expression upper limit marks; 7 expression air cavitys; 8 expression imbibition layers; The scalable film of 9 expressions; 10 expression sap cavities.
Embodiment
The utility model will be further described below with reference to accompanying drawing and by embodiment.
As shown in Figure 1 and Figure 2, simple and easy soil moisture content indicating device has a cavity 2, the one side of cavity 2 is a pervious bed 1, pervious bed 1 adopts the good hard microporous stupalith of water permeability to make, pervious bed 1 inboard is equipped with the imbibition layer 8 that adopts polyacrylamide to make, imbibition layer 8 inboard are equipped with fluid-tight scalable film 9, in the sap cavity 10 of scalable film 9 inboards indicator solution is housed, one graduated tube 4 that indicates scale 5 is arranged on the cavity 2, communicate with sap cavity 10 in the graduated tube 4, there is an air cavity 7 on graduated tube 4 tops; Because the solable matter content difference of different soils, the imbibition degree of imbibition layer 8 is also just different, be provided with movably upper limit mark 6 and lower limit mark 3 on the graduated tube 4, the height that indicator solution reached of this device when being used to refer in same soil water saturation respectively and when dry is so that people contrast reference when operation.When using this device to indicate the water cut of soil, in only cavity 2 need being placed into the soil, graduated tube 4 exposes native face, this moment, pervious bed 1 lateral surface closely contacted with soil, moisture in the soil can see through pervious bed 1 and be absorbed by imbibition layer 8, imbibition layer 8 absorbs the moisture after expansion, indicator solution in the compressing sap cavity 10 enters graduated tube 4, water cut is high more in the soil, 8 suction of imbibition layer are just many more, its degrees of expansion is just big more, and the indicator solution that enters graduated tube 4 is also just many more, and the liquid level of indicator solution is also just high more; Otherwise water cut is few more in the soil, and 8 suction of imbibition layer are just few, and its degrees of expansion is just more little, and the indicator solution that enters graduated tube 4 is also just few more, and the liquid level of indicator solution is also just low more.This device just shows the height of water cut in the soil by the liquid level in the graduated tube 4, also can read the concrete numerical value of water cut by scale 5, and with reference to predefined upper limit mark 6, lower limit mark 3, in time understand the water cut situation of soil, so that people control the humidity of soil exactly when plantation, maintenance, improve the success ratio of plantation, maintenance.
The utility model volume is small and exquisite, easy to carry, with low cost, operation is simple and easy, can be positioned in all size flowerpot and common field, and can be placed in the soil in use always, so that grasp the water cut situation of soil whenever and wherever possible.
