Abstract

The invention provides a stirrer and a liquid plastic limit testing device, and relates to the technical field of soil measuring equipment. The stirrer comprises a stirring shaft and a stirring unit,wherein the stirring shaft is connected with one end of the stirring unit; the other end of the stirring unit is arranged in a way of being opposite to a soil sample to be tested in a sample cup; thestirring shaft can move and rotate in the vertical direction so that the soil sample can be stirred or sheared by the stirring unit; the other end of the stirring unit and the horizontal plane are arranged in a way of forming an inclination angle theta; the other end of the stirring unit is in smooth arrangement. The technical problems that in the prior art, the testing device requires the manualoperation on the cone falling during titration, artificial interference exists, the calibration result is influenced, the errors are great are solved. The stirring unit and the horizontal plane are arranged in the way for forming the inclination angle theta; the accuracy of the test result is ensured; the problem that the cone surface cleanness cannot be ensured during the manual cone falling operation can be avoided.

Description

technical field [0001] The invention relates to the technical field of soil measuring equipment, in particular to a stirrer and a liquid-plastic limit measuring device. Background technique [0002] Fine-grained soil is in a fluid state, a plastic state, a semi-solid state and a solid state due to the difference in water content. The liquid limit is the upper limit moisture content of the fine-grained soil in a plastic state, and the plastic limit is the lower limit moisture content of the fine-grained soil in a plastic state. The liquid-plastic limit index of fine-grained soil is the most basic index for its classification and naming. In geotechnical engineering, the accuracy of the liquid-plastic limit index involves the correctness of soil naming, and at the same time affects the determination of the state of the soil sample, which in turn affects The determination of the bearing capacity of the soil and the correct determination of the liquid-plastic limit index of the ...
