Description
Technical field
The present invention relates to field planting environmental monitoring, particularly to a kind of sensor of the measurement soil weight.
Background technology
The soil weight refers to the weight of solid in unit volume soil, is the important physical character of reflection soil density and porosity status.Crop root being distributed and its absorption to water and nutrient, the motion of the activity of soil microorganism, soil moisture and gas and exchange process, soil by machines performance in soil(Including contractility, tilth and aggregate stability etc.), migration in soil for the pollutant and conversion and soil runoff and erosion process etc. all have close relationship with the soil weight.The technology measuring the soil weight is more, and the method for the traditional measurement soil weight has core cutter method, wax coating method etc., simple and easy to do and precision is higher.But the Spatial Variability due to soil characteristic, needs the sample of greater number can obtain representative observation.Meanwhile, Field sampling is wasted time and energy, serious to soil fail, and sampling and measuring not reproducible to same place is it is difficult to realize location observation.
The probe of current Thermo-TDR probe is thinner, diameter only has 1.3 millimeters, spacing is less, it is about 6 millimeters, and length is 40 millimeters, research shows, in heat capacity of volume measurement, the error of probe spacing (r) is the key factor of impact thermal pulse technology measurement result, is also the source of error place that this sensor measures the soil weight.When probe insertion soil, the distance between two probes often changes a lot, and leads to reality(r)Value changes and then brings the evaluated error of unit weight.
Content of the invention
In order to solve the above problems, the present invention provide one kind can convenient and swift regulation probe spacing from reducing evaluated error, structure is simple, the convenient measurement soil weight sensor making.
For realizing the object of the invention, there is provided technical scheme below:A kind of measurement soil weight sensor,Including probe、The handle of fixing probe、Cable tester、Cable、Data collecting instrument and DC source,Probe includes heated probe、Temperature probe,It is characterized in that handle includes fixed platform and clamping set,Fixed platform center is longitudinally spaced apart and is provided with strip draw-in groove,Clamping set reciprocatingly slide can with strip draw-in groove clamping and along strip draw-in groove,Strip draw-in groove both sides are provided with and are provided with threaded plastic card article,Clamping set outer wall is provided with auricle,Bail is provided with auricle,The bail hole clipping that open up corresponding with threaded plastic card article connects and fixes,Probe is inserted in clamping set,Described tips of probes is helical form syringe needle,It is filled with high conductive material in probe,Probe includes a heated probe、Two temperature probes,Two temperature probes are divided into positioned at heated probe both sides,Described heated probe is internally provided with insulation resistance and thermocouple,It is provided only with thermocouple inside temperature probe,The center copper wire welding of cable is in heated probe upper-end part of driving,The reticulated conductive layer of cable periphery is divided into two strands of equivalent,It is respectively welded at two temperature probe upper ends,Cable is connected to cable tester,Insulation resistance connects DC source,Thermocouple is connected with data collecting instrument.
Preferably, handle material is epoxy resin.
Preferably, clamping set endoporus is provided with Memorability block rubber, probe inserts in fixing on Memorability block rubber.
