Description
Technical field
The present invention relates to a kind of test apparatus, in particular to one kind is stopped angle measuring instrument.
Background technique
It will form a cone when granular solids material natural packing, the angle of cone generatrices and bottom surface, which is called, to stop
Angle, what is indicated is the frictional property of raw material inherence itself, also known as angle of static friction or stocking angle.The material of good fluidity
Grain will be tumbled in the gradient of very little, can be only formed very short cone, therefore angle of repose is small.And the material meeting that mobility is bad
Very high cone is formed, angle of repose is larger.The angle of repose of material is the important indicator for evaluating material fluidity.Meanwhile it is same
When combustion is close, the angle of repose of material accumulation should also be as be it is close, when material itself pass through naked eyes be difficult to judge when,
Can whether consistent close to the type for carrying out auxiliary judgment material by the angle of repose of material accumulation.The object of use for laboratory at present
Material heap product angle of repose measuring instrument be usually used it is static after natural packing after, prevent angle measurement equipment in material cone side,
Manual measurement reading, this number reading method influenced by sight angle it is big, if every time reading when sight angle there are deviation,
Then reading will have deviation, and especially for the material that cone stacks, error in reading is bigger.Also have to irradiate using light and throw
Shadow assists reading, and this mode is high to the stability requirement of light source, if light source position changes, will also result in projection and become
Shape, in addition, the projection that light irradiation material cone generates, in the edge effect easy to form of taper profile line, the module of boundary of projection
Paste, causes measurement error.
