The invention discloses a device for rapidly testing a repose angle of a granular material. A rectangular transparent bucket (4) is arranged on a chassis (2) with a flatting and height-adjusting device (1) through a hinge device (12); an incompletely sealed baffle (6) is arranged inside the rectangular transparent bucket (4); a movable sealing cover plate (7) is arranged at the top part of the rectangular transparent bucket (4); a forked tail-type sliding groove (9) is arranged outside the front wall and the rear wall of the rectangular transparent bucket (4) in the vertical direction; a measuring plate (10) with angle lines is installed inside the sliding groove (9); and a channel (13) of the measuring plate (10) is formed in the chassis (2). Compared with the prior art, not only is the repose angle of the granular material under natural atmosphere tested, but also the repose angle of the granular material in artificial pressure state can be tested, and the repose angle of the granular material with large moisture content, particularly saturated moisture content or even in over-saturated state, can be tested, and moreover the testing speed is high.
Description
technical field [0001] The invention relates to an instrument for measuring the angle of repose of granular materials, in particular to a device for rapidly measuring the angle of repose of granular materials. Background technique [0002] At present, the existing measuring devices can only measure the angle of repose of granular materials under natural atmospheric pressure; they cannot measure the angle of repose of granular materials under artificial pressure; they cannot measure particles with a large water content, especially when the water content is saturated or even supersaturated Angle of repose of the material, and the measurement speed is slow. Therefore, it is necessary to design a rapid determination of the angle of repose of granular materials that can not only measure the angle of repose of granular materials under natural atmospheric pressure, but also can measure the angle of repose of granular materials under artificial pressure. Device is a technical prob...
