Embodiment Construction

[0052] The following is attached Figure 1-7 The application is described in further detail.

[0053] In the related art, when carrying out the determination test of the limit moisture content, it is generally necessary to prepare three kinds of humidity soil samples according to the requirements, which are respectively low-humidity soil samples, medium-humidity soil samples and high-humidity soil samples, and put the three kinds of soil samples respectively The liquid-plastic limit tester generally includes a base, a conical drop weight located above the base, and a reading device for measuring the insertion depth of the conical drop weight into the soil sample. Generally speaking, the reading device adopts the method of image acquisition, and the image of the conical drop hammer inserted into the soil sample is directly projected onto the light-transmitting reading plate to realize the reading. With the development of science and technology, infrared distance measurement is ...

Abstract

The application relates to a laboratory soil sample preparation line, which relates to the field of soil sample preparation, which includes a crushing device, a screening device, a material distribution device, a mixing device and a sample preparation device. The application has the effect of reducing the manpower input of manual sample preparation in the soil test process. The present application also relates to a soil sample preparation method of a laboratory soil sample preparation line, including a crushing step, a sieving step, a material dividing step, a stirring step, a standing step and a sample preparation step.

Description

technical field [0001] The present application relates to the field of soil sample preparation, in particular to a laboratory soil sample preparation line and a soil sample preparation method thereof. Background technique [0002] At present, in the process of soil testing in the laboratory, it is often necessary to prepare different soil samples according to different requirements of the test. Among them, the preparation process of soil samples is generally completed manually. [0003] In the related technology, in the determination test of the limit moisture content, it is generally necessary to crush, sieve, add water and mix the retrieved soil sample, let it stand, prepare the test soil sample and other steps, and finally put the prepared solid soil sample into the The liquid-plastic limit tester is used for detection and relevant values ​​are obtained. According to the test requirements, three kinds of soil samples with different humidity need to be prepared in one tes...
