青混凝土摊铺机规格型号较多，各类型的摊铺机结构也不尽相同，但其结构一般由机架、 动力系统（含发动机、液压传动系统）、行走系 统、电控系统、收料输料系统（含前推辊、收料 斗、刮板输料器、螺旋分料器）、调平系统、熨平装置等组成。上述结构中，除了熨平装置以外，均属于主机的主要组成部分。
There are many specifications and models of green concrete pavers, and the structure of each type of paver is also different. However, its structure is generally composed of a frame, power system (including engine and hydraulic transmission system), walking system, electric control system, material receiving and conveying system (including front push roller, material receiving hopper, scraper conveyor, screw distributor), leveling system, ironing device, etc. In the above structures, except for the ironing device, they all belong to the main components of the host machine.
主机的主要功能包括以下 4 个方面：一是牵引摊铺机整体行走，并为摊铺机各个系统提供动力；二是通过主机前部的推辊推动运料自卸车行进，使其完成向收料斗卸料作业；三是通过刮板输送器和螺旋分料器将收料斗接收的混合料输送到摊铺宽度范围以内；四是连接并支撑熨平装置，为其液压回路提供动力，并可调整熨平板位置高度和作业角度。
The main functions of the host include the following four aspects: firstly, it pulls the overall travel of the paver and provides power for each system of the paver; The second is to push the material unloading truck forward through the push roller at the front of the host, so that it can complete the unloading operation to the receiving hopper; The third is to transport the mixture received by the receiving hopper to the paving width range through a scraper conveyor and a spiral distributor; The fourth is to connect and support the ironing device, provide power for its hydraulic circuit, and adjust the position, height, and working angle of the ironing plate.
Structure and working principle of ironing device
The ironing device is the main working device of the asphalt concrete paver, which is hinged to the main machine through the lifting cylinders and large arms on both sides of the main machine. The fully functional ironing device consists of a box body, a main ironing plate (main board), a secondary ironing plate (auxiliary board), a widened ironing plate (extended section), a scraper guard plate, an end plate, a vibrating mechanism, a vibrating mechanism, a thickness regulator, a camber adjustment mechanism, a heating system, etc.
摊铺机主机后部及熨平装置前部均设有护板，熨平装置两端设有端面挡板，由此在熨平装置前部形成 1 个储存沥青混凝土的摊铺材料室。其中端面挡板可使摊铺层获得较平整的边缘，可调高度的熨平板把混合料刮到预铺高度。沥青混凝土经振捣夯锤振实后，在熨平板底面和振动器的共同作用下，形成具有一定密实度的沥青路面摊铺层。
The rear of the paver host and the front of the ironing device are equipped with protective plates, and the two ends of the ironing device are equipped with end face baffles, forming a paving material room for storing asphalt concrete in the front of the ironing device. The end face baffle can provide a smoother edge for the paving layer, and the adjustable height iron plate scrapes the mixture to the pre laid height. After being compacted by a vibrating hammer, asphalt concrete forms a dense asphalt pavement layer under the joint action of the bottom surface of the screed and the vibrator.
