Problems solved by technology

[0003] At present, most people only conduct experiments on mix ratio design, durability demonstration, trial paving of test road sections, and adjustment and optimization of paving machinery. The control is different, and the combination ratio of the optimal aggregate particle size and the optimal cement dosage in accordance with the local area cannot be obtained according to the different conditions of each area, so it is impossible to truly improve the skeleton compactness of the cement-stabilized gravel base Excellent fatigue resistance and crack resistance;

Embodiment 1

[0044] Embodiment 1, this embodiment provides an intelligent aggregate proportioning platform scale, refer to the attached figure 1 As shown, a mounting base 1 is included and a collecting tube 2 is fixedly arranged on the mounting base 1. It is characterized in that a screening cavity 3 is installed on the upper end of the collecting tube 2, and the collecting tube 2 is located below the screening cavity 3 to rotate. A loading plate 4 is installed and a number of storage boxes 5 are fixedly installed at intervals on the loading plate 4. The screening chamber 3 can be used to screen aggregates of different particle sizes mixed together and aggregate the aggregates in our required particle size range. The material is stored in the corresponding material storage box 5, and the bottom of the screening chamber 3 is provided with a leak hole 51, and a discharge device is installed at intervals below the leak hole 51 in the collection cylinder 2, and the discharge device will dischar...

Embodiment 2

[0050] Embodiment 2, on the basis of embodiment 1, with reference to appended image 3 As shown, the unloading device is a unloading roller 13 coaxially rotated and installed in the storage box 5, and the bottom of the unloading roller 13 is threaded with the tapered valve 7, and the unloading roller 13 is fixed by Driven by the blanking motor 14 on the top of the material storage box 5 (in this scheme, the motor controller of each blanking motor 14 is electrically connected with the micro-control processor, when the belt scale 9 detects that the material storage box 5 is discharged When the aggregate reaches the set value, the micro-control processor controls the corresponding working blanking motor 14 to reverse), and when the blanking motor 14 drives the blanking roller 13 to rotate, the aggregate in the storage box 5 is The trend of downward movement, see attached Figure 6 As shown, there are vertically extending chutes 15 on both sides of the inner axis of the lower mat...

Embodiment 3

[0051] Embodiment 3, on the basis of embodiment 2, with reference to appended Figure 4 , 7 As shown, the coaxial center of the lower material barrel 6 is provided with an annular cavity 19 that communicates with the chute 15 and is rotatably fitted with the annular ring 8. The vertical length of 15 is set in steps (that is, the top heights of chute 15 in different lower barrels 6 are the same, but the heights of the bottom ends of chute 15 in different lower barrels 6 are different, so the circular rings in different lower barrels 6 circle 8 is located at different heights), refer to the attached Figure 5 , 7 As shown, the axial sides of the annular ring 8 are provided with limit holes 20 matched with the chute 15, and the tapered valve 7 drives the slide rod 16 fixedly connected with it to move to the limit hole 20 under the drive of the blanking motor 14. At the upper end face, the annular ring 8 is in the positioning state under the action of the positioning block 21 a...

Abstract

The invention relates to an intelligent aggregate proportioning platform scale, which effectively solves the problem that the existing aggregate proportioning platform scale cannot automate the proportioning test for the optimum particle size aggregate and the optimum cement dosage according to needs; The technical scheme includes: the intelligent aggregate proportioning platform scale can complete the proportioning between aggregates of different particle sizes and the corresponding cement dosage, and carry out the compression test on the test pieces made under the corresponding proportioning, and finally get the final result. The mixing ratio of the best aggregate particle size and the best cement dosage, and under the action of the mixing platform scale, the whole test mixing process is highly automated, which provides greater convenience for the work of the test personnel and greatly reduces the Reduced the labor intensity of the test personnel.

Description

technical field [0001] The invention relates to the technical field of aggregate proportioning, in particular to an intelligent aggregate proportioning platform scale. Background technique [0002] With the continuous increase of traffic volume, large-scale vehicles, and the phenomenon of overloaded transportation becoming more and more serious, the requirements for road performance are getting higher and higher, and the role of the pavement base is gradually highlighted. The performance and regional characteristics are gradually improving, but the construction technology level in each region is different, and there are different cognitions on the mix ratio construction control of the skeleton-dense cement-stabilized macadam base. It is necessary to further obtain the mix ratio requirements that meet the local area according to its own requirements and characteristics. ; [0003] At present, most people only conduct experiments on mix ratio design, durability demonstration,...
