Abstract
The invention discloses a mobile regenerated asphalt mixture cold mixing device which comprises a mobile semi-trailer unit and a fixed external suspended unit, wherein, the semi-trailer unit comprises a semi-trailer chassis, a hopper, a single aggregate hopper, double aggregate hoppers and an impeller feeding machine which are mounted at the top part of the chassis, a screw conveyor, an aggregatefeeding conveyor, a mixing cylinder mounted at the lower part of the chassis, an emulsified asphalt spraying system and a water supply system; the fixed external suspended unit comprises an unloadingconveyor, a small hopper, a loading screw conveyor, a powder silo, an asphalt supply system and a control chamber; and the control chamber and the asphalt supply system are respectively arranged on the outer sides of the mobile semi-trailer unit. The mobile regenerated asphalt mixture cold mixing device has the advantages of reasonable layout and full functions, the external suspended unit has fewer devices, and the disassembly and the assembly are simple and convenient, thereby facilitating the movement operation of highway construction units. The mobile regenerated asphalt mixture cold mixing device is used for paving a basic layer of a highway after full mixing by adding raw materials of emulsified asphalt, cement, mineral powder and the like, and the manufacturing cost and the using cost are much lower than those of the prior asphalt stirring device.
Description
Mobile recycled asphalt mixture cold mixing equipment technical field The invention relates to a mixing equipment for recycled asphalt mixture used for paving base layers of road surfaces, in particular to a mobile operation equipment capable of mixing and cold mixing waste asphalt scraps without heating, and belongs to the technical field of road construction machinery. Background technique Asphalt mixing equipment is used to process the waste asphalt scraps milled from the old road surface so that they can be reused. The existing recycled asphalt mixing equipment usually heats the waste asphalt scraps to 160°C to 200°C. °C, blended into the new material at a ratio of not more than 50%, and the asphalt mixture can be paved on the road again by heating and stirring. This equipment solves the problem of recycling waste asphalt fragments milled out in asphalt pavement maintenance, and is beneficial to environmental protection. However, the cost of this asphalt waste recycli...
