Milling machine dust falling equipment for old road disease repairing construction

The invention relates to milling machine dust falling equipment for old road disease repairing construction, and belongs to the field of milling machines. The equipment comprises an arc-shaped material guide barrel connected with the end part of a conveyor belt device, a dust baffle device connected with the material guide barrel, arranged above a hopper of a transport vehicle and used for reducing the diffusion of waste dust or fine particles, and a water mist spraying mechanism used for spraying water mist into the hopper so as to accelerate the precipitation of the waste dust or the fine particles. The dust baffle device comprises a dust baffle above the hopper, a pair of side dustproof mechanisms used for connecting the dust baffle with the left side wall and the right side wall of thehopper, a first end dust blocking mechanism arranged at the end, away from a vehicle head, of the hopper, and a second end dust blocking mechanism arranged at the end, close to the vehicle head, of the dust baffle.
