Soil liquid-plastic limit combined tester for water conservancy project

Abstract

The invention discloses soil liquid-plastic limit combined tester for a water conservancy project. The tester comprises a base, two ends of a lower surface of the base both are provided with support legs, one end of an upper surface of the base is provided with a tester main body, the tester main body and the base are structurally integrated, one end of a front surface of the base is provided witha protective cover, a connection part between the protective cover and the base is provided with a hinge, and the protective cover is rotationally connected with the base through the hinge. With a hollow column designed on the upper surface of the base, influence on a measurement result caused by instability of a sample cup placed on the upper surface of a lifting platform in use is avoided, rotation of a hand wheel can be started after a handle is hold by one hand, rotation of the hand wheel droves a connection rod to rotate at the inside of the hollow column, thus, an end part of the connection rod is connected with the inside of a clamp board through screwing, the clamp board and an external surface of the sample cup are fixed closely, and a problem of influence on the measurement result caused by instability of the sample cup is solved.

Description

technical field [0001] The invention belongs to the technical field of soil liquid measurement, and in particular relates to a combined measuring instrument for soil liquid plastic limit used in water conservancy projects. Background technique [0002] The existing combined soil liquid-plastic limit measuring instrument for water conservancy projects adopts technologies such as digital display, and can self-time, measure and display. It has the characteristics of stable performance, reliable data, high measurement accuracy, intuitive and clear readings, simple and convenient operation, and high work efficiency. When the liquid-plastic limit combined tester is used, the sample cup is placed on the upper surface of the lifting platform, which is unstable, which affects the measurement results. After use, the sample cup needs to be placed in a separate storage box, which is inconvenient to organize. For this reason, we propose a combined soil liquid-plastic limit tester for wa...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a combined soil liquid-plastic limit tester for water conservancy projects, to solve the above-mentioned background technology. The combined tester for soil liquid-plastic limit for water conservancy projects puts the sample cup on the upper surface of the lifting platform during use. It is unstable when used, which affects the measurement results. After use, the sample cup needs to be placed in a separate storage box, which is inconvenient to organize.
