Description

Technical Field

[0002] Asphalt concrete is a mixture of steel slag, mineral materials, gravel and other materials with road asphalt materials. Currently, asphalt concrete is mostly used for road construction and road repair. With the development of urban road construction, the demand for asphalt concrete is increasing.

[0003] After searching, it was found that the asphalt concrete mixing device in the prior art, such as announcement number CN221000442U, includes a base plate, a mixing drum is fixedly installed on the right side of the upper end of the base plate, and a support block is fixedly installed on the left side of the upper end of the base plate. The utility model pours aggregate into a feeding box, and the grinding roller crushes the aggregate into small pieces and drops them into the cylindrical block. The spiral blade rotates to push the crushed materials upward. When the crushed materials reach the top, they fall through the feed pipe into the mixing drum, and the stirring rod drives the stirring paddle to stir. After the stirring is completed, the valve is opened to discharge the material. The device crushes the aggregate into crushed materials by the grinding roller, which can improve the quality of the finished asphalt mixture. The feeding mechanism effectively allows the crushed materials to enter the mixing drum, saving labor. The mixing drum is equipped with stirring blades with different inclination angles to push the asphalt concrete, making it more thoroughly mixed and improving efficiency. The temperature generated by the heating plate is conducive to the mixing of asphalt and aggregate, and will not cause the asphalt to stick to the stirring paddle, which is conducive to the discharge of asphalt concrete.

[0004] In summary, the existing asphalt concrete mixing device can improve the quality of the finished asphalt mixture, but the existing asphalt concrete mixing device is prone to stratification and uneven mixing. Therefore, an asphalt concrete heating and stirring device is proposed. Utility Model Content
