The invention relates to the technical field of road administration construction, in particular to an environment-friendly integrated vehicle with
powder spreading and mixing functions, which comprises a spreading vehicle, a feeding mechanism, a spreading mechanism, a
protection mechanism and a competition mechanism, and the feeding mechanism, the spreading mechanism and the competition mechanism are mounted on the spreading vehicle. A water spraying mechanism is mounted on the
material scattering vehicle, and an adjusting mechanism is connected to the water spraying mechanism; under the action of the feeding mechanism and the
material scattering mechanism, materials can be conveniently placed into the
material scattering vehicle to be stored, automatic closing protection is achieved, meanwhile, the materials can be conveniently guided out to be scattered, under the action of the
protection mechanism, material guiding of the material scattering mechanism is facilitated, blockage caused when the materials are scattered is prevented, and the service life of the material scattering vehicle is prolonged. And meanwhile, under the action of a
locking mechanism, the
protection mechanism is conveniently stored, under the action of a water spraying mechanism, water spraying and dust removal can be conveniently conducted on the
road surface, the water spraying direction can be conveniently adjusted and controlled, and operation is more convenient.
