Abstract
The utility model relates to a soil water content tester. The soil water content tester comprises a contained soil mixing and agitating device, an electronic weighing device, an alcohol injection and ignition device, a display control panel and a charging battery, wherein the contained soil mixing and agitating device comprises three soil containers with the same size; an agitating blade is mounted at the lower middle part of each soil container and is fixedly arranged on a transmission shaft; each transmission shaft passes through a hole in the bottom of the corresponding soil container 2 and is driven by a motor. The agitating blades on the transmission shafts are used for agitating and mixing a soil sample, and the soil sample and alcohol can be sufficiently mixed for combustion, so that the combustion time is shortened and the measurement error is reduced; the determination time can be shortened to the greatest extent; operations of weighing, mixing, liquid injection, ignition and the like can be automatically carried out in a full process, so that the testing efficiency is improved greatly and personal errors are eliminated.
Description
Technical field
The utility model relates to a kind of geotechnological surveying instrument, relates in particular to a kind of soil basis determining instrument.
Background technology
At present, the assay method of soil moisture content mainly comprises gravimetric method, Neutron probe method, electric-resistivity method, gamma-rays transmission beam method, TDR method and FDR method etc.Wherein, gravimetric method refers to by free state water in soil moisture is all lost with vapor form, then weighs, thereby obtains the method for soil water content.Gravimetric method is a kind of the most frequently used method of current mensuration soil moisture content, and it is simple, has enough precision, is the basic skills of determining soil moisture, is also the basis of inspection additive method and its contrast.Gravimetric method mainly comprises oven drying method, alcohol combustion method, fried dry method, infrared method, the roasting method of stove etc.
Alcohol combustion method is applicable to the water percentage of fast simple mensuration fine grained soil, is also the rapid assay methods that building-site is conventional.Its ultimate principle is to utilize alcohol repeatedly in soil sample, to burn, and makes in soil sample moisture evaporation, by soil sample dry rear mensuration dry before and after the quality of soil sample, obtain this soil sample water cut.
For ensureing whole evaporations of moisture in soil sample, testing requirements soil sample can not be too large, and little soil sample often makes measurement result representativeness weaken; In process of the test, by knocking weighing box, alcohol and soil sample are fully mixed, but for the poor soil sample of perviousness, mixed effect is poor, thereby the error of measurement result also can be larger; In addition, test need to be carried out the replicate determination of 2～3 times, has greatly increased minute, and manual operation has also increased the possibility that personal error occurs greatly.
Summary of the invention
In order to overcome the deficiency of existing alcohol burning Methods for Measuring Soil Water Content: A, the utility model provides a kind of alcohol burning soil basis determining instrument.
The technical solution of the utility model is: a kind of soil basis determining instrument, comprise and contain native mixed stirring device, electron mass meausring apparatus, alcohol injects and portfire, display control panel and rechargeable battery, contain the soil filling device that native mixed stirring device comprises three same sizes, soil filling device is put into analyzer base by limiting chute, stirring vane is equipped with in each soil filling device bottom, stirring vane is fixed on hollow drive shaft, hollow drive shaft is driven by motor through the hole of soil filling device bottom, by the stirring vane on hollow drive shaft, soil sample is uniformly mixed, electron mass meausring apparatus comprises electronic scales and push rod, alcohol injects with portfire and comprises alcohol liquid reserve tank, connecting pipe and nozzle, alcohol liquid reserve tank is connected with the hollow drive shaft of soil filling device bottom by connecting pipe, alcohol flows out from the nozzle at hollow drive shaft top, between liquid reserve tank and connecting pipe, by-pass valve control is installed, the installation position of alcohol liquid reserve tank will be higher than nozzle, and display control panel is connected with storage calculating control circuit plate, and measurement data is stored, calculated and shows.
The beneficial effects of the utility model: can make the abundant mix burning of soil sample and alcohol, shorten burning time, reduce measuring error; Replicate determination is carried out simultaneously, shortens to greatest extent minute; The operations such as overall process automatically weighs, mixes and stirs, fluid injection, igniting, have improved the efficiency of measuring greatly, have eliminated the generation of personal error.
