Description

Technical Field

[0001] The utility model relates to the technical field of cement-stabilized crushed stone, in particular to a regenerated cement-stabilized crushed stone structure. Background Art

[0002] Cement-stabilized crushed stone is a mixture with graded crushed stone as aggregate, a certain amount of cementitious materials and sufficient mortar volume to fill the gaps in the aggregate, and mainly relies on the interlocking principle between crushed stone and crushed stone to form a mixture with certain mechanical strength and density. Because of the effect of cement, it has high strength at the beginning, and with the increase of age, the strength increases and forms a whole. Because of its high strength and rigidity, it is widely used in highway base construction. Cement-stabilized crushed stone has good plate properties, and its water stability and frost resistance are better than lime-stabilized soil. In order to improve the processing efficiency of water-stabilized crushed stone, a recycled cement-stabilized crushed stone structure is needed, but the existing recycled cement-stabilized crushed stone structure still has the following shortcomings:

[0003] For example, the utility model with application number 201720790341.2 discloses a uniform water adding device for recycled cement-stabilized gravel mixture. The utility model has a simple structure and is easy to use. It is easy to disassemble and install, can quickly deal with internal blockage and damage of the nozzle, and has the effect of fixed plug-in position to achieve the effect of uniform water spraying, thereby effectively improving work efficiency. However, similar to the comparative documents of the above-mentioned application, when the existing cement-stabilized gravel structure is used, since most cement-stabilized gravel structures are not easy to add asphalt mixtures and other waste materials to the cement-stabilized gravel, the road performance of the cement-stabilized gravel is poor, resulting in the problem of reduced practicality and reduced use efficiency of the cement-stabilized gravel structure.

[0004] Therefore, in view of this, the existing structure and defects were studied and improved, and a recycled cement stabilized gravel structure was proposed. Utility Model Content

[0013] Furthermore, there are two scraper plates, and the outer sides of the scraper plates are tightly fitted to the inner wall of the mixing tank.

[0014] The utility model provides a recycled cement stabilized gravel structure, which has the following beneficial effects:

[0015] 1. The utility model can, through the arrangement of a mixing component, avoid the problem that most cement-stabilized gravel structures are not easy to add asphalt mixture and other waste materials into cement-stabilized gravel when the recycled cement-stabilized gravel structure is used by utilizing the mixing component arranged at the lower end of the mixing tank, resulting in poor road performance of the cement-stabilized gravel and the problem of reduced practicality of the cement-stabilized gravel structure. The mixing box is fixedly installed at the lower end of the mixing tank, and the mixture of cement, gravel and water in the mixing tank enters the mixing box through the discharge port. The output shaft of the servo motor installed in the middle part of the lower end of the mixing box is connected to the support rod through a coupling.

The output shaft of the motor installed in the middle of the upper end of the mixing tank is connected to the sun gear through a coupling. The operation of the motor drives the sun gear to make the stirring rod rotate inside the mixing tank. The mounting frame is fixedly installed at the front end of the stirring rod through the fastening bolts, and the scraper plate is fixedly installed on the outside of the mounting frame with the fastening bolts. Then, when the stirring rod rotates, the mounting frame and the scraper plate are driven to rotate. Mixing water is injected into the mixing tank through the water inlet opened at the upper right end of the mixing tank, and a sufficient amount of cement is added into the mixing tank. At the same time, the outer side of the scraper plate is tightly fitted with the inner wall of the mixing tank, thereby preventing the mixture from adhering to the inner wall of the mixing tank, thereby increasing the use efficiency of the cement-stabilized gravel structure.
