A swing arm control mechanism 7 that can drive the swing arm 704 to rise and fall and swing is provided on the vehicle body 101, and a cleaning device 8 and a suction nozzle device 10 are provided on the lower side of the outer end of the swing arm 704. The suction nozzle device 10 is located at the rear side of the cleaning device 8, and the suction nozzle device 10 is connected to the suction device. During operation, the collection vehicle travels to the side of a train cargo compartment 11. The swing arm control mechanism 7 controls the swing arm 704 to raise and swing, placing the cleaning device 8 and the suction nozzle assembly 10 into the train cargo compartment 11. The cleaning device 8 collects the remaining material on both sides of the train cargo compartment 11 toward the center after unloading. As the collection vehicle moves forward, the suction nozzle assembly 10 and the air suction device collect the remaining material into the trash bin 5. Preferably, the swing arm 704 is tubular, with its outer end curved downward to form an outer boom 7041. The cleaning device 8 and the suction nozzle assembly 10 are mounted at the lower end of the outer boom 7041. The lower end of the outer boom 7041 is connected to the suction nozzle assembly 10, and the inner end of the swing arm 704 is connected to the trash bin 5 via a flexible suction pipe docking device 6. The tubular swing arm 704 also serves as a suction duct, significantly reducing its weight and the workload of the collection vehicle and the swing arm control mechanism 7. It also reduces the number of additional pipes on the swing arm 704, simplifying the structure of the collection vehicle.

[0029] like Figure 1 、 Figure 4 、 Figure 7 and Figure 8As shown, the elastic docking device 6 of the suction pipe is arranged between the trash bin 5 and the swing arm control mechanism 7, and is used to ensure the sealed connection of the air duct during the cleaning operation, including a curved suction pipe 604, the top of the curved suction pipe 604 is opened upward and is provided with a sealing device 601, the sealing device 601 can be a sealing ring or a sealing gasket provided at the top opening of the curved suction pipe 604, the bottom end of the curved suction pipe 604 is sealed with a soft suction pipe 603, the soft suction pipe 603 is sealed with a steel suction pipe 602, the steel suction pipe 602 is connected to the trash bin 5, and the inner end of the swing arm 704 is provided with an inner boom extending downward. 7042, the inner arm 7042 is also tubular, and the cavity within the inner arm 7042 communicates with the cavity within the swing arm 704.
