Baseline measuring instrument for geochemical test

Abstract

The invention provides a baseline measuring instrument for geochemical testing, and relates to the technical field of measuring equipment, the baseline measuring instrument comprises a main body, the top of the main body is provided with two slots, and the top of the main body is provided with a discharge assembly; the discharging assembly comprises supports and a second vertical rod, the supports are installed on the two sides of the top of the main body, a motor is installed on the top of the outer side of one support, a bevel gear is installed at the output end of the motor, a threaded rod is installed on the side face of the top of the other support, and the second vertical rod is of a cylindrical structure and installed on the outer side of the corresponding support through a bearing seat. And the swinging assembly is mounted at the top of the main body. And the volumes of the storage tanks are the same, and the dosage of the added measurement volume is the same when the rotating rod rotates for one circle, so that the problem that in the measurement process, the dripping dosage is observed through visual inspection, so that the measurement result has an error due to slight difference of the measurement solution is solved.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a measuring instrument used for the baseline of geochemical testing. Background technique [0002] Geochemical baseline refers to the natural changes in the concentration of chemical elements in the earth's surface materials, and is an important reference to distinguish between natural and man-made environmental impacts. Use a measuring instrument to confirm the lithium, sodium, magnesium, aluminum, and silicon in soil samples by titration. Baseline values ​​of other elements. [0003] However, when the existing measuring instrument is used, the sample particles in the soil sample are different, which makes the fusion efficiency of the sample and the measurement solution different, resulting in certain errors in the measurement results. Inject the measurement solution, and observe the dripped dose by visual inspection, so that there is a slight difference in the meas...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing measuring instrument is used, the sample particles in the soil sample are different, which makes the efficiency of the fusion of the sample and the measurement solution different, resulting in the measurement result There is a certain error, and in the process of measurement, by manually dropping the measurement solution and visually observing the dropped dose, there is a slight difference in the measurement solution, and the different dosage of the measurement solution leads to errors in the measurement results
