Moisture is the principal element of decision soil dielectric constant.The specific inductive capacity of measured soil can directly stably react the true moisture of various soil.Soil moisture is the important component part of soil, and the growth of crop, water-saving irrigation etc. are had important effect.Grasp the distribution situation of the moisture (soil moisture content) of soil by system, irritate the foundation that science generally is provided for the water saving of differentiation, simultaneously accurate water supply also helps improving the yield and quality of crop.
The utility model content
At above shortcomings part in the prior art, the technical problems to be solved in the utility model provides a kind of measurement mechanism that is used for the soil permeability parameter.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The measurement mechanism of a kind of soil permeability parameter of the utility model, have earth-containing groove and water box, wherein earth-containing groove is located on the water box, for the antiseep periphery connects by sealing gasket, the earth-containing groove bottom land is provided with the infiltration hole, the earth-containing groove sidewall is provided with a plurality of instrument probe hole, and a plurality of TDR soil moisture sensors place the soil of earth-containing groove by the instrument probe hole, and the detection signal of TDR soil moisture sensor is connected to supervisory control comuter by single-chip microcomputer and converter.
Described water box top opening is provided with the load-bearing band; Described water box bottom is provided with water drain valve; Described water box bottom is equipped with instrument stand.
The utlity model has following beneficial effect and advantage:
1. installation and maintenance are easy and simple to handle.The utility model adopts earth-containing groove and the removable structure of water box, and earth-containing groove is provided with the instrument probe hole, is easy to install and safeguard.
2. long service life.Water box of the present utility model is that organic glass is made, and instrument stand adopts epoxy resin as propping material, and water box top opening is provided with the load-bearing band, and intensity and life-span are guaranteed.

Fig. 2 is the utility model split structural representation.
Embodiment
As Fig. 1, shown in 2, the measurement mechanism of a kind of soil permeability parameter of the utility model, have earth-containing groove 1 that organic glass makes and water box 2 wherein earth-containing groove 1 be located on the water box 2, water box 2 is supported by instrument stand 6 (present embodiment employing epoxy resin), the contact periphery at position of earth-containing groove 1 and water box 2 tightens up connection by sealing gasket 3 via screw 7, earth-containing groove 1 bottom land is provided with infiltration hole 4, earth-containing groove 1 sidewall is provided with instrument probe hole 8, a plurality of TDR soil moisture sensors 9 place the soil 10 (present embodiment adopts 10 TDR soil moisture sensors 9) of earth-containing groove 1 respectively by different instrument probe holes 8, the detection signal of TDR soil moisture sensor 9 is connected to supervisory control comuter 14 by single-chip microcomputer 12 and converter 13; Water box 2 top openings are provided with load-bearing band 15.Described water box 2 bottoms are provided with water drain valve 5.
The operating voltage of TDR soil moisture sensor 9 is DC12v, the signal of output 4～20mA, the live part length of measured soil〉600mm, length＜100mm near cable section, TDR soil moisture sensor 9 must contact closely with soil, guarantee the soil fill sensor, the distance between the sensor is approximately 100mm, keeping parallelism.An optional method is that the mud of making of local soil is in advance injected along the instrument probe hole 8 of TDR soil moisture sensor 9, inserts sensor then.These mud are with the gap between fill sensor and the soil.Horizon sensor will be installed in the earth-containing groove, with fluid sealant mouth be sealed then.
During use, by external water controller 11, according to required soil permeability parameter, time and consumption artificial water application, after water enters soil in the earth-containing groove 1, promptly begin soil permeability, should stop to supply water when soil moisture content reaches capacity, water flows in the water box 2 through infiltration hole 4 by soil at this moment, is equipped with survey after water drain valve 5 flows out.This model adopts the structure of sealing gasket 3 and fixed screw 7, and sealing effectiveness is better.Measuring system is finished by TDR soil moisture sensor 9, and measuring-signal is transported to supervisory control comuter 14 through single-chip microcomputer 12 converters 13.
Moisture is the principal element of the specific inductive capacity of decision soil.The specific inductive capacity of TDR soil moisture sensor measured soil, the direct true moisture of stably measuring various soil.Aspect agricultural, the output of the signal of sensor can be used for directly controlling irrigating.For example: during antecedent soil moisture, caution signal can sound reminds people should irrigate that time is up automatically.Automatic control system energy switch water pump and valve etc.Cooperate some additional sensors, may can calculate soil water evaporation amount and the required water parameters of crops.But the percent by volume of TDR measured soil moisture is irrelevant with the mechanism of soil own.
