The invention discloses an environment-friendly coal-loading and smoke-guiding integrated vehicle and an operation method thereof. The environment-friendly coal-loading and smoke-guiding integrated vehicle comprises a steel structure platform, a walking device, a coal hopper device, a weighing system, a spiral feeding device, a cab, an electrical chamber, a hydraulic chamber, a lubricating system,a hydraulic system, a U-shaped tube device I, a cover uncovering device, a furnace seat cleaning device, a furnace cover cleaning device, a cover uncovering device, a guide sleeve device, a water supply system, a gate plate device, a U-shaped tube device II, an air conditioning system, a sliding contactor device and an electrical system. Generally, characteristics of a top-loading and tamping dual-purpose coke oven are combined, and the novel technology of the environment-friendly coal-loading and smoke-guiding integrated vehicle is developed, and two functions of a top-loading coke oven coalloading vehicle and a tamping coke oven gas guiding vehicle can be achieved. A production process of coke can be timely adjusted according to the change of the coke market and coking coal resources,and rapid switching of the two functions can be realized. The environment-friendly coal-loading and smoke-guiding integrated vehicle not only can be used for loading coal in a top loading process, butalso can be used for guiding smoke in a tamping process, smokeless coal loading can be realized, and production efficiency and economic benefits of enterprises can be improved.
