As, it is necessary to the voidage of strict control bituminous pavement；In concrete proportioning design, voidage can be used as control aggregate
Gradation and the foundation for calculating sand factor；The quality and density for usually requiring measurement accumulation bulk granular material, could obtain material
Voidage, but the measurement of quality of material need to be measured by container, and measurement method is relatively complicated, and human factor is more, influences
Measurement result；And if the measurement of apparent density encounters scleroid bulk granular material, such as sand, stone, need to wear into fine powder measurement
Its apparent density, time-consuming, effort generally measure its density approximation instead of its apparent density in application process, cause larger mistake
Difference.It is therefore proposed that a kind of realization device of determining accumulation bulk granular material voidage, may be implemented to be precisely calculated accumulation and dissipates
The voidage of granular material, and be generalized to apply in various industries and be of great significance.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of device of determining accumulation bulk granular material voidage, energy
Enough solving the prior art, that there are measurement methods is relatively complicated, and time-consuming, effort, human factor is more, be easy to cause large error shadow
The problems such as ringing measurement result.
The present invention is implemented as follows:
A kind of device of determining accumulation bulk granular material voidage, described device includes: fixed frame, laser measuring apparatus, biography
Band, water tank, water level display and liquid level sensor are sent, a cross bar is provided on the fixed frame, the laser measuring apparatus is solid

Sensor electrical connection.
Further, the laser measuring apparatus is line laser measuring instrument or two dimensional laser scanning measuring instrument.
The present invention has the advantage that
The present invention is not necessarily to carry out the measurement and calculating of quality of material, density, and structure is simple, and convenient for operation, it is accurate to realize
The voidage for calculating accumulation bulk granular material, improves work efficiency, and saves human resources.
[Detailed description of the invention]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a kind of structural schematic diagram of the device of determining accumulation bulk granular material voidage of the present invention.
Fig. 2 is the coordinate schematic diagram of present invention acquisition material natural packing volume
