A kind of preferred as the utility model Repose angle gauge, the first inclined-plane of described charging hopper is glass surface; The second inclined-plane of described charging hopper is metal covering; Described charging hopper front and back sides is glass surface; The first inclined-plane and front and back sidewall adopt glass to reduce sidewall friction, and the accumulation body angle of repose problem less than normal that causes is impacted in the particle tenesmus when having avoided the funnel method to survey the angle of repose.
Another kind as the utility model Repose angle gauge is preferred, and described charging hopper bottom incline and base are hinged; Thereby make rotation more convenient.
Another kind of preferred as the utility model Repose angle gauge also comprises dismountable baffle plate, and described baffle plate is located in the charging hopper, with the first side, the second side or front and back sides is movable is connected; By using baffle plate to form certain space in the charging hopper bottom, test materials thereby reduce.
Another kind as the utility model Repose angle gauge is preferred, also comprises height gauge, on described height gauge is located on charging hopper the first inclined-plane; The preferred 2-5 of described height gauge, and equidistant be located on charging hopper the first inclined-plane on; The setting of a plurality of height gauges can be piled up the position from difference and be measured the angle of repose, improves measuring accuracy.
Another kind as the utility model Repose angle gauge is preferred, also comprises vertical scale, and described vertical scale is located at base top; Can measure the angle of repose of charging hopper testing material at an arbitrary position the time.
Another kind as the utility model Repose angle gauge is preferred, and described jacking gear is comprised of hand runner and lifting screw, makes lifting screw control the angle of charging hopper and surface level, more convenient operation by hand runner.
Another kind as the utility model Repose angle gauge is preferred, also comprises and revolves pin, and the described pin that revolves is located at the base bottom, is used for the adjusting gear level, guarantees that measurement result is accurate.
During use, the charging hopper top is transferred to level, charging is also adjusted the material surface level; Slowly rotate charging hopper by jacking gear, when material will slide, read the reading on height gauge and the vertical scale, can calculate static angle of repose.
Beneficial effect: a kind of Repose angle gauge that the utility model provides is simple in structure, easy to operate, antijamming capability is strong, measuring accuracy is high, is specially adapted to the mensuration at cohesiveless soil angle of repose.
This analyzer can obtain the angle of repose of cohesiveless soil easily and accurately, has avoided the disturbance in the material formation stockpile process when measuring the angle of repose, is convenient to not slide between control test earth material surfacing and earth material and charging hopper base plate the measuring accuracy height.
