Drying rack of soil drying box for measuring water content of soil

Abstract

The invention relates to the technical field of soil detection, and discloses a soil drying box drying rack for soil water content determination, the soil drying box drying rack comprises a drying box shell, one side of the drying box shell is fixedly connected with an air inlet, and the two sides of the interior of the drying box shell are fixedly connected with partition plates; a heater is fixedly mounted at the bottom end of the partition plate close to one side of the air inlet, a rotating shaft is fixedly mounted in the middle of the partition plate on the other side, a drying frame is movably connected through the rotating shaft, a filter screen is fixedly mounted at the bottom end of the partition plate on the other side, and a motor is fixedly mounted at the bottom end of the other side of the drying box shell; and fan blades are fixedly mounted at one end of the motor. By means of self-adjustment of the wind plate, heat loss in the initial starting stage is small, after the temperature rises to the set temperature, the piston of the main adjusting rod is pushed by expansion gas to move upwards, the drying frame is pushed to incline right opposite to the direct blowing face of circulating wind, and therefore the contact area between circulating hot air and soil is increased, and the soil drying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil drying oven rack for measuring soil water content. Background technique [0002] Soil testing is to measure the representative values ​​of soil components and factors affecting soil environmental quality, so as to determine the soil environmental quality and its change trend. The steps generally include point sampling, sample preparation, analysis method, result characterization, data statistics and quality evaluation, etc. Technical content, during the sample preparation process, the sampled soil needs to be dried. Generally, the water content of the collected soil sample is between air-dried and water-saturated. It will affect the test results, so the soil samples need to be dried, and the commonly used equipment is the soil drying box. [0003] However, the drying racks of the existing soil drying boxes are all fixed structures, and the installation of the dryin...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing soil drying oven rack proposed in the background technology, the present invention provides a soil drying oven rack for soil moisture content measurement, which has the advantages of flexible and adjustable angle of the drying rack, and the convective air volume can be adjusted at any time. The advantages of automatic control due to changes in soil moisture content solve the technical problems of fixed drying racks, low contact efficiency of hot air and complicated regulation of circulating air volume proposed in the above background technology
