By adopting the integral design, the asphalt mixture measuring instrument has simple structure and convenient application and operation, can realize the real-tine and rapid measurement of the quality variability of the asphalt mixture in a laboratory, a mixing plant and the construction site, is mainly used for detecting the variation of the target proportion and the variation degree of the asphalt mixture during the construction process, and also can be used for detecting whether the asphalt mixture is isolated.
Description
Technical field
The utility model belongs to road engineering material design and construction field control technical field, is specifically related to a kind of asphalt analyzer.
Background technology
At present, the early damage phenomenon of bituminous pavement is very general, and in fact, all there is water destruct in various degree in the highway of use more than 1 year, and difference is that part highway breakoff phenomenon is serious, and the partial destruction phenomenon is lighter.The relevant expert thinks that asphalt mixture segregation is to cause the basic reason of road surface local damage when analyzing bituminous pavement early damage phenomenon.At present, adopt the extracting instrument that compound is carried out the mensuration of grading analysis and bitumen content usually, perhaps adopt firing method that compound is carried out grading analysis.These the two kinds problems that all exist test period relatively to grow to detection method of bituminous mixture, the result comes out by the time, and the making highway section is compaction moulding, can't correct undesirable making highway section; Simultaneously, measure the temperature of asphalt by the technician, judge whether temperature meets the requirements, the index that lacks a science goes to judge whether these compounds meet the demands, also lack field quick detection equipment, cause in time to adopt the means of science to pinpoint the problems and deal with problems.In a word, traditional detection method is not easy to operate, and detection time is long, can not play the effect of real-time control asphalt work progress quality.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of asphalt analyzer is provided, this asphalt analyzer is simple in structure, use easy to operate, production cost is low, can realize in real time, the quality of the asphalt of measure field apace, judge whether morph by testing result.If morph, then according to the size that makes a variation, take the corresponding technical measures punishment, thereby effectively prevent the road surface early disease that asphalt mixture segregation causes, prolong the serviceable life of bituminous pavement, social benefit and economic benefit are widely arranged, can save a large amount of engineering maintenance costs simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of asphalt analyzer, comprise the chassis, it is characterized in that: be fixed with portal trestle on the described chassis, the portal trestle upper end is equipped with the hopper holder, is placed with hopper in the hopper holder, feed hopper bottom one side is hinged with baffle plate, the baffle plate below is provided with the hopper switch that is used to control baffle plate, is positioned at the portal trestle inboard on the described chassis and is provided with outer disc and disk, the central lines of chassis, outer disc and interior disk.
The utility model compared with prior art has the following advantages:
(1) simple in structure, use easy to operate.
(2) production cost is low, reduces investment.
(3) can realize in real time, the quality of the asphalt of measure field apace.
(4) integrated design, volume are less, easy to carry.
(5) to the test site no requirement (NR).
(6) applied widely, the compound that is not only applicable to the working-yard is taken a sample, and also is applicable to the compound sampling of testing laboratory and batching plant.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment
A kind of asphalt analyzer as depicted in figs. 1 and 2, comprise chassis 1, be fixed with portal trestle 2 on the described chassis 1, portal trestle 2 upper ends are equipped with hopper holder 3, be placed with hopper 4 in the hopper holder 3, hopper 4 bottoms one side is hinged with baffle plate 5, and baffle plate 5 belows are provided with the hopper switch 6 that is used to control baffle plate 5, be positioned at portal trestle 2 inboards on the described chassis 1 and be provided with outer disc 8 and disk 9, the central lines of chassis 1, outer disc 8 and interior disk 9.
Spiral distributor 7 is installed in the hopper 4.Spiral distributor 7 can make asphalt in hopper 4 during landing speed reduce, thereby it is more even that asphalt is scattered on outer disc 8 and interior disk 9, measurement result is more accurate.
The round heart in hopper 4 bottom surfaces is positioned at directly over 1 center of circle, chassis.The round heart in hopper 4 bottom surfaces is the asphalt center of being scattered, 1 center of circle, chassis is the center of outer disc 8 and interior disk 9, the round heart in hopper 4 bottom surfaces is positioned at directly over 1 center of circle, chassis, be asphalt be scattered the center that is centered close to outer disc 8 and interior disk 9 directly over, making asphalt that one side does not take place in the process of being scattered during work is scattered many, one side few situation of being scattered, thus the accuracy of measurement result do not influenced.
1 center, chassis is provided with columnar projections 10, and outer disc 8 and interior disk 9 centers are provided with the aperture that matches with described columnar projections 10.When placing outer disc 8 and interior disk 9, the aperture of outer disc 8 and interior disk 9 directly is placed on the columnar projections 10 of 1 center, chassis, can be easy to make the center of outer disc 8 and interior disk 9 to overlap like this with 1 center, chassis.
The course of work of the present utility model is: asphalt is put into hopper 4, open hopper switch 6, asphalt falls in The One On The Chassis outer disc 8 and the interior disk 9 after slowing down through spiral distributor 7.With balance the asphalt that falls in outer disc 8 and the interior disk 9 is weighed respectively, calculate the quality of asphalt in the outer disc 8 and the number percent of regulation sample mass, this ratio is called the segregation index, judges the size that asphalt morphs by this ratio.
When if the number percent of the quality of asphalt and regulation sample mass is big in the outer disc 8, show that this asphalt emanates easily, the asphalt of this grating type has bigger kinetic energy, work progress, the asphalt particle rolls easily, and therefore mixture segregation just takes place easily; If the number percent of the quality of asphalts and regulation sample mass hour in the outer disc 8, show that this asphalt is difficult for emanating, the asphalt of this grating type has less kinetic energy, work progress, the asphalt particle is difficult for rolling, and therefore just is difficult for taking place mixture segregation.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
