Angle of repose measuring device

Abstract

The present invention discloses an angle of repose measuring device, and belongs to the field of geotechnical test equipment. The angle of repose measuring device comprises a base, a mounting plate arranged on the base, a mounting groove arranged in the mounting plate, and a measuring scale which is arranged in the mounting groove and is rotatably connected with the mounting plate; the upper surface of the base is arranged parallel to the lower surface of the base; the measuring scale is provided with a scale; the open side of the mounting groove is arranged in the same plane as the side of the base; the longitudinal section of the mounting groove is a quarter of a circle; the center axis of the mounting groove is arranged on the rotation axis of the measuring scale; and the base is provided with a level bubble. According to the angle of repose measuring device provided by the present invention, the function of measuring the angle of repose of solid particles is realized, the error generated in the measurement of the angle of repose of solid particles is reduced, the measurement accuracy is improved, the operation is convenient and rapid, and the measurement efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of geotechnical test equipment, in particular to an angle of repose measuring device. Background technique [0002] The angle of repose refers to the maximum angle between the natural slope formed by the solid particle material and the horizontal plane when the solid particle is piled up in a loose state under the action of the gravity field, which reflects the frictional properties of the original solid particle itself, also known as accumulation angle or angle of static friction. The fluidity of solid particles cannot be expressed by a single specific value, but the size of the angle of repose can reflect the friction properties of the solid particles themselves, so the angle of repose is often used to express the fluidity of solid particles. Solid particles with good fluidity cannot maintain balance on a slope with a small slope, so the angle of repose formed is small, and solid particles with poor fluidity can fo...

Problems solved by technology

At present, the structure of the equipment for measuring the angle of repose in geotechnical tests is relatively simple. It is judged whether the measured angle is the angle of repose through the line of sight. Due to the error of line of sight judgment, there is a large error between the measured angle and the real angle of repose, which seriously affects the test results, and the operation is not easy. Convenience, great impact on work efficiency
