Abstract

The invention relates to the technical field of soil mechanical composition analysis, in particular to an automatic soil mechanical composition measuring device. The device comprises a settling vat, a gravitometer, a laser displacement sensor and a master control system, wherein the laser displacement sensor is arranged over the settling vat, the gravitometer is arranged in the settling vat, a laser reflection device is arranged at the top end of the gravitometer, a laser emission direction of the laser displacement sensor faces the right lower portion, and the main control system comprises a displacement acquisition module and a reading determination module; the displacement acquisition module is used for acquiring a displacement value, detected by the laser displacement sensor, of the gravitometer; and the reading determination module is used for determining the reading of the gravitometer according to a preset relation equation between the displacement value and the reading of the gravitometer. The soil mechanical composition can be accurately measured by adopting the automatic soil mechanical composition measuring device.

Description

Technical field [0001] The present invention relates to compositions Field soil mechanical analysis, particularly relates to an automatic measuring device consisting of mechanical soil. Background technique [0002] Natural soil is composed of soil particles of different sizes, including sand, powder (sand) and particles cosmid. Each share of grain size in the soil or relative proportions of mass fraction, referred to the soil mechanical composition. Soil mechanical composition not only an important diagnostic indicator of soil classification, but also affect soil water, fertilizer, gas, thermal state, material transport and transformation process research and an important factor in the degradation of soil, the soil is also the geographical research, and agricultural production related to soil improvement, an important research area of ​​civil engineering and water cycle processes. [0003] The method of analyzing the composition of a conventional mechanical soil There are two ma...
