Problems solved by technology

However, in traditional asphalt mixing, the three cannot be efficiently mixed to form an optimal stable structure.
There are three main defects: one is that the asphalt is poured into the mineral material in a relatively concentrated manner, resulting in uneven thickness of the asphalt layer on the surface of the mineral material, and even the phenomenon of "blocking"
The second is that the addition of mineral powder to the asphalt mineral mixture is uneven, and the phenomenon of "agglomeration" of mineral powder and asphalt is easy to occur. The third is that the moveme

Abstract

The invention relates to a stirring device for an asphalt mixture. The stirring device for the asphalt mixture comprises a primary stirring bin and a secondary stirring bin, wherein a blast type mineral powder spraying device and an air pressure type asphalt spraying device are arranged in the primary stirring bin, and a half bin type rotating stirring device is positioned at the lower part of theprimary stirring bin; a double horizontal shaft paddle stirring device is arranged in the secondary stirring bin, and a discharge port is formed on the lower end of the secondary stirring bin; the primary stirring bin is supported above the secondary stirring bin by a frustum-shaped sliding vertical support device. For the engineering problems in the prior art, the stirring device for the asphaltmixture aims at realizing efficient mixing of aggregate, asphalt and mineral powder. Through changing the mixing form of the asphalt mixture, the free movement state and effective spraying area of the mineral powder are increased, the spraying uniformity of the asphalt and the mineral powder is increased, the full range coverage of a discrete mineral powder region is realized, and the mixing quality and the mixing efficiency of the asphalt mixture are improved.
