More than be the main composition and the operating principle of present asphalt pavement maintanance truck, shortcoming is to dry and mix and stir to be intermittent operation, and each finished product material discharging time is longer, and production efficiency is low, and operation is interior because the loss of waste heat causes oil consumption to be increased interval, and cost of production increases.
Summary of the invention
Goal of the invention of the present utility model is to overcome above-mentioned deficiency, and a kind of production efficiency height, asphalt pavement maintanance truck that cost of production is low are provided.
For achieving the above object, the utility model asphalt pavement maintanance truck comprises chassis, power set, dram, mixing cylinder, power set drive dram, mixing cylinder rotates, building stones are sent building stones into mixing cylinder and are mixed and stirred the discharge of formation bituminous concrete with the pitch that sprays into after the dram oven dry.
Asphalt pavement maintanance truck of the present utility model adopts the double-barrel structure of dram, mixing cylinder, with former operation program: charging-dry-mix and stir-discharge is divided into the mode that two stages finish by a tube, change the mode that dram, mixing cylinder are uninterruptedly finished continuously into, thereby shortened the finished product material greatly, be the discharging time of bituminous concrete, improved the production efficiency of bituminous concrete; In addition, the intermittent operation of working continuously than the monotubular structure of dram has reduced heat-energy losses, has reduced the consumption of oven dry fuel oil, has reduced the cost of production of bituminous concrete.
