Description

High-solid-content emulsified asphalt full-reclaimed asphalt mixture paver Technical Field The invention belongs to the field of highway equipment, and particularly relates to a high-solid-content emulsified asphalt full-reclaimed asphalt mixture paver. Background The full-reclaimed asphalt with high solid content is a full-deep cold reclaimed pavement technology which uses high solid content emulsified asphalt as a core reclaimed binder to perform cold mixing and on-site paving and rolling on old asphalt pavement milling materials (RAP), does not need to heat mixed materials in the whole process, relies on the cohesiveness and stability of the high solid content emulsified asphalt, realizes 100% recycling of the old materials, and is one of the main stream technologies in the field of asphalt pavement reclamation. The water content in the high-solid-content emulsified asphalt fully-recycled asphalt mixture is from the water phase of the emulsified asphalt and the added water, the water content has the function of ensuring the workability of the emulsified asphalt before demulsification and facilitating paving, but too much water can delay demulsification and strength development, too little water can lead to the early demulsification of the emulsified asphalt, and the mixture is hard and loose. The optimal water content is generally controlled to be 3% -5% (adjusted according to the water content of the old materials and the ambient temperature), and the judgment standard is that the mixture is agglomerated by hand, scattered when falling to the ground and free water is not obvious on the surface. The existing road paving mainly depends on a paver to pave, when paving, materials are conveyed into a hopper of the paver through a material conveying vehicle, mixed materials are conveyed into a distributing groove at the rear of a host machine through a scraper conveyer at the bottom of the hopper, the mixed materials are uniformly distributed along the paving width by a spiral distributor, the problem of water content reduction is caused due to weather and other reasons in the process of conveying the mixed materials, and thus the phenomenon of napping is caused, water is hardly added into the hopper or the distributing groove to ensure the uniformity of water, and the local water delays demulsification and strength development, so that the problem of supplementing certain water in the paving process is the problem which needs to be solved at present. Disclosure of Invention Aiming at the technical problems existing in the prior art when the high-solid-content emulsified asphalt full-reclaimed asphalt mixture is paved, the invention provides the high-solid-content emulsified asphalt full-reclaimed asphalt mixture paver which has the advantages of reasonable design, simple structure, convenient processing and capability of effectively improving the water content. In order to achieve the aim, the technical scheme includes that the high-solid-content emulsified asphalt full-regeneration asphalt mixture paver comprises a frame and a scraper conveyor rotatably arranged on the frame, wherein the scraper conveyor comprises a left conveyor and a right conveyor which are arranged left and right, a protective cover is further arranged on the frame, the protective cover is arranged between the left conveyor and the right conveyor, a main frame is further arranged at one end of the frame, a material dividing pipe is arranged on the frame, the material dividing pipes are arranged on two sides of the frame, an auxiliary material dividing pipe is arranged on the protective cover, the material dividing pipe and the auxiliary material dividing pipe are arranged below the main frame, the material dividing pipe and the auxiliary material dividing pipe are arranged at intervals along the moving direction of the scraper conveyor, the material dividing pipe and the auxiliary material dividing pipe are arranged above the scraper conveyor, the material dividing pipe and the auxiliary material dividing pipe are arranged in a triangular prism shape, one side of the material dividing pipe and the auxiliary material dividing pipe, which is far away from the moving direction of the mixture, and an atomizing nozzle is arranged on one side of the material dividing pipe and the auxiliary material dividing pipe.
