Background technology:
Fine aggregate is the aggregate that a kind of diameter is relatively little, is the building materials relative with coarse aggregate, specifically refers to the aggregate of particle diameter at below 4.75mm, plays the granular loose material of skeleton or filling effect in concrete.In traditional idea, the understanding of people to fine aggregate has prejudice more, mostly thinks that the effect of fine aggregate in concrete is insignificant, as long as think that ropy fine aggregate is added cement and can be made up its inferior position; But from the analysis of modern concrete idea and facts have proved, the cement consumption in concrete increases, not only with high costs, and cause concrete to heat up, distortion even reduces elastic modulus, causes concrete permanance seriously to reduce.Therefore, the effect of fine aggregate in concrete is extremely important, it not only plays skeleton function, stress can be transmitted, support load-carrying, and there is the function suppressing to shrink, prevent cracking, the concrete of proper use of fine aggregate is conducive between aggregate, the combination of aggregate and cement, more can reduce porosity, reduce cement consumption, such that concrete density is large, impervious, good frost resistance.
Therefore, the appearance features of fine aggregate has important meaning to improving concrete performance, but traditional measuring method can not obtain about the too many characteristic information of fine aggregate, and then along with the development of science and technology, image analysis technology (DIP technology) is applied in building materials analysis, DIP technology is by obtaining aggregate picture, with professional software, the aggregate in picture is analyzed again, then by professional software, two-dimension analysis is carried out to draw the technology of related data to the fine aggregate in picture.But, for the image acquisition of building materials aspect, normally carry out under plane, static state, if but fine aggregate for building is by traditional image analysis method, on the one hand, tiny fine aggregate particle is not easy to be disperseed, and is difficult to the particle image be separated completely; On the other hand, the length and width size a two-dimensional surface can only be obtained from the fine aggregate of plane shooting, more multi-section dimension information cannot be obtained; If imagination can be taken the process that fine aggregate falls in the air from height, fine aggregate more comprehensively form parameter will be obtained, yet there are no in currently available technology and utilize aggregate to fall or upthrow carries out device or the method for shooting, collecting parameter, therefore the utility model works out a kind of image diversion harvester, is specially adapted to for describing the appearance features of fine aggregate.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that prior art exists, and seeks to design a kind of image diversion harvester for fine aggregate, and while can disperseing fine aggregate, shooting, collecting is to distributed image clearly.
To achieve these goals, the image diversion harvester agent structure for fine aggregate of the utility model design comprises No. I fixed mount, No. II fixed mount, No. I support, No. II support, flow chamber, light source, picture pick-up device, funnel and measuring chamber, No. I fixed mount that structure is identical and No. II fixed mount are separately positioned on the left and right sides of flow chamber, the upper end of No. I fixed mount is provided with No. I support of Collapsible structure for fixed support light source, the upper end of No. II fixed mount is provided with No. II support of Collapsible structure for fixed support picture pick-up device, light source and picture pick-up device are fixedly mounted on the upper end of No. I support and No. II support respectively, the top and bottom of the flow chamber of hollow type spatial structure are the trapezoidal groove of hollow structure, funnel installation by adhering in the trapezoidal groove of flow chamber upper end for toppling over fine aggregate, the inside middle installation by adhering of flow chamber has the measuring chamber of flat rectangular structure, dilute solution is equipped with for collecting, dispersion fine aggregate in measuring chamber inside, so that picture pick-up device gathers image.
Preferably, No. I fixed mount, No. II fixed mount and flow chamber are positioned on same level line; No. I support and No. II support symmetrically formula structure, the light source that it is installed respectively and picture pick-up device are all corresponding with measuring chamber.
Preferably, the trapezoidal groove area of flow chamber upper end is less than the trapezoidal groove area of lower end, to ensure the stability of flow chamber entirety; Dilute solution is the solution that density is less than fine aggregate bulk density, comprises tap water, seawater, massfraction be the sodium-chloride water solution of 3-10%; Funnel is the hollow rectangular parallelepiped of flat, and its volume is less than flow chamber intermediate volume.
The utility model compared with prior art, utilize the dilute solution in measuring chamber not only to limit the region but also disperse fine aggregate of falling of fine aggregate, coordinate fixing light source and picture pick-up device to carry out shooting continuously with the particle complete image collecting fine aggregate simultaneously; Distinctive solution designs solves fine aggregate because of excessive velocities under placement in height, disperse everywhere, causes the picture taken to take off shadow phenomenon; Single unit system is Demountable, is convenient to dismounting cleaning; Its structure is simple, and design science is easy and simple to handle.
