Abstract
The utility model discloses a soil moisture measuring device. The measuring device comprises a measuring barrel body (2) with scale marks (1), and at least two soil moisture sensors (4) with probes (3) are arranged on the wall of the measuring barrel body (2) from top to bottom. The soil moisture measuring device has the advantages of being simple in structure, convenient to operate and low in cost, and can quickly and conveniently measure the soil moisture under different depth. The accuracy of measurement results can be ensured, and the service life of the device can be prolonged.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of soil humidity measuring device.
Background technology
At present, varied for the measuring method of soil moisture, still, the shortcoming that the existence more or less of these methods is certain.For example sampling drying weight method, exist length consuming time, expense high, there is the shortcomings such as destructive; , there is apparatus expensive in NEUTRON METHOD, and must strictly observe the shortcoming of radiation method; The conductivity method, be subject to the impact of type and the salinity of material, has the shortcomings such as result is accurate not.The most simply and accurately method is " otdr measurement ", and measurement result can obtain immediately, and without destructiveness, but sensor need be imbedded to the soil of different depth when measuring different depth soil moisture in, larger soil moisture has seriously shortened its life-span.
Summary of the invention
The purpose of this utility model a kind ofly can be carried out to the soil of different depth the soil humidity measuring device of moisture measurement with regard to being to provide.
The purpose of this utility model is to realize by such technical scheme, a kind of soil humidity measuring device, described measurement mechanism comprises the measurement cylindrical shell with scale mark, is provided with at least two soil humidity sensors with probe on the barrel of described measurement cylindrical shell from top to bottom.
Further, described each soil humidity sensor is with at least two probes, and the probe of described each soil humidity sensor all is positioned on the same level line.
Wherein, described each probe stretches out barrel 3-5cm by the aperture on barrel.
Owing to having adopted technique scheme, the utlity model has advantage simple in structure, easy to operate, with low cost, adopt it conveniently to be measured the soil moisture of different depth, not only guaranteed the accuracy of measurement result, and extended the serviceable life of instrument.
The accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
The vertical view that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of soil humidity measuring device, described measurement mechanism comprises the measurement cylindrical shell 2 with scale mark 1, is provided with at least two soil humidity sensors with probe 34 on the barrel of described measurement cylindrical shell 2 from top to bottom.
Wherein, described each soil humidity sensor 4 is with at least two probes 3, and the probe 3 of described each soil humidity sensor 4 all is positioned on the same level line.So just can record on the same level line, the humidity of the soil of diverse location, more can obtain measuring numerical value accurately.
In order to guarantee the accuracy of measuring, described each probe 3 stretches out barrel 3-5cm by the aperture on barrel.
The utility model is to use like this: when needs are measured soil moisture, in only the utility model vertically need to being placed into the soil, probe 3 can be measured with the soil close contact.By measuring the scale mark 1 on cylindrical shell 2, can determine the distributed depth of soil sensor, by measuring cylindrical shell 2, can not damaged by higher levels of humidity and other by soil protection humidity sensor 4, increase the service life.
In the utility model, the position of probe 3 and quantity can arrange voluntarily according to actual conditions.Probe 3 can arrange two, also can arrange three, four, can also arrange a plurality of.
Claims (3)
1. a soil humidity measuring device, it is characterized in that: described measurement mechanism comprises the measurement cylindrical shell (2) with scale mark (1), is provided with at least two soil humidity sensors with probe (3) (4) on the barrel of described measurement cylindrical shell (2) from top to bottom.
2. soil humidity measuring device as claimed in claim 1, it is characterized in that: described each soil humidity sensor (4) is with at least two probes (3), and the probe (3) of described each soil humidity sensor (4) all is positioned on the same level line.
