Problems solved by technology

However, the accuracy of this kind of experiment is not high due to manual operation, and the operation is designed to be automated, and it is difficult to control the height of the liquid sucked by the liquid collector. In practice, no sampling device that will measure the dosage of lime or cement in stabilized soil has been found. Designed as a precedent for automated sampling

no. 1 example

[0037] The first embodiment: as Figure 1-2 , as shown in 7-10,

[0038] The sampling device for determining the dosage of lime or cement in stabilized soil includes a sampling support 1 and a sample container 2, wherein the sampling support 1 is fixed with an agitator 3, and the lower end of the agitator 3 extends into the sample container 2 and Submerged below the liquid level of the sample container 2, a liquid extractor 4 is provided on the sampling support 1, and the liquid extractor 4 is arranged above the sample container 2 in a liftable manner. When the liquid extractor 4 is lowered, the lower end of the liquid extractor 4 is submerged The liquid surface of the sample container 2 is below.

[0039] In the embodiment, the stirrer 3 is provided with a motor 31 , and the liquid extractor 4 is placed vertically and controlled by the lifting frame 5 .

[0040] In the embodiment, the sample container 2 is placed on the support base 11 of the sampling support 1 , the suppor...

no. 2 example

[0053] The second embodiment: as Figure 3-4 , as shown in 7-10,

[0054] The difference between the second embodiment and the first embodiment is that the mark rod 51 is not used to indicate the depth below the liquid surface of the sample container 2 where the liquid extractor 4 is inserted, and the scale is directly engraved on the liquid extractor 4 to indicate the liquid extractor 4 Insert sample container 2 to a depth below the liquid level.

[0055] In the embodiment, the liquid taker 4 is provided with a scale for marking the depth of the liquid taker inserted into the sample container 2 below the liquid surface, and the sample container 2 is a transparent container.

[0056] A sampling method for a sampling device for measuring lime or cement dosage in stabilized soil, wherein, comprising the following steps:

[0057] Step 1. Take 1000g of medium and coarse-grained soil samples and add them to the sample container 2;

[0058] Step 2, pour into the ammonium chloride...

[0064] The third embodiment: as Figure 5-10 as shown,

[0065] The present embodiment has adopted a kind of novel liquid taker 4, and this liquid taker has its unique structure and usage.

[0066] In the embodiment, the liquid taker 4 includes a liquid taker straw 41 and a liquid overflow container 42, the upper end of the liquid taker straw 41 is inserted into the overflow container 42 and the lumen volume of the liquid taker straw 41 is equal to the target liquid volume value. Adaptation, the overflow container 42 is provided with a negative pressure generating device 43 that can generate negative pressure in the overflow container 42 and a pressure relief port 44 that makes the negative pressure in the overflow container 42 disappear. The overflow container 42 The lower part is provided with a liquid discharge port 45 .

[0067] In this embodiment, a high-precision liquid extraction is realized through a liquid-taking device straw 41 adapted to the target liquid-taking v...

Abstract

The invention discloses a sampling device for measuring dosage of lime or cement in stabilized soil and relates to the technical field of measurement devices. The sampling device comprises a sampling bracket and a sample container, wherein a stirrer is fixed on the sampling bracket; the lower end of the stirrer stretches into the sample container and sinks to be under a liquid level of the sample container; a liquid extractor is arranged on the sampling bracket; the liquid extractor is arranged above the sample container in a liftable manner; when the liquid extractor falls, the lower end of the liquid extractor sinks to be under the liquid level of the sample container. The sampling device has the advantages of simple structure, low cost, high automation degree and high liquid extraction accuracy.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to soil composition measurement, in particular to a sampling device and a sampling method for measuring the dosage of lime or cement in stabilized soil. Background technique [0002] Composition testing is mainly to detect the known components of the product, and to perform qualitative and quantitative analysis on the known components. In order to verify whether it is produced in strict accordance with the provided formula and requirements. Composition detection (including composition detection and composition test items) is a technical method for analyzing unknown components through spectra. The content of soil components is generally determined by laboratory analysis. However, the existing soil composition measurement, especially in engineering The measurement of the dosage of lime or cement in commonly used lime or cement-stabilized soil is all purely manual operation,...
