Problems solved by technology

For example, if quantitative funnel or quantitative cup is directly used for sample quantification, there are often operational errors, and the latter two quantitative devices have relatively high requirements on the fluidity of the quantified substance, so it is very important to develop a sample quantitative sampling device for soil thermoluminescence measurement. necessary

The quantitative sampling device comprises a funnel disc (1), a quantitative disc (2) and a quantitative platform (3), wherein the funnel disc (1) is fixedly connected with the quantitative platform (3) through a connecting shaft (15), and the quantitative disc (2) is arranged between the funnel disc (1) and the quantitative platform (3); the quantitative disc (2) is connected with the connecting shaft (15) through a shaft hole in a swinging manner, the funnel disc (1) is provided with a discharge abdication port (9), the quantitative disc (2) is provided with a revolution abdication port (10), and a limiting bolt (7) is arranged in the revolution abdication port (10) and is connected with the funnel disc (1) or and the quantitative platform (3); one side of the revolution abdication port (10) is connected with the limiting bolt (7) in a limiting manner, the outlet of a funnel (8) is corresponding to the inlet position of the quantitative guide hole (11), and the other side of the revolution abdication port (10) is connected with the limiting bolt (7) in the limiting manner; and the outlet of the quantitative guide hole (11) is corresponding to the inlet position of the discharge guide hole (14), and the inlet position of the quantitative guide hole (11) is arranged in the discharge abdication port (9). The sampling device provided by the invention ensures the sample to be quantitative and the operation to be simple and rapid.

Description

technical field [0001] The invention belongs to the technical field of metering, and relates to a quantitative sampling device, in particular to a quantitative sampling device for soil thermoluminescence measurement samples. Background technique [0002] In soil thermoluminescence measurement, it is necessary to quantify the samples in order to ensure the comparability of the measured data. However, the number of the same quantitative samples required for each sample measurement is as many as several hundred to one thousand. If a balance is simply used to weigh and determine the samples, not only a highly sensitive balance is required, but also multiple weight adjustments are required. The speed is time-consuming and labor-intensive. Existing quantification techniques usually directly use quantitative funnel or quantitative cup for sample quantification, or combine quantitative funnel (cup) for design, such as application number CN200820156029.9, title "A High-precision Qua...
