The utility model relates to the technical field of environmental protection equipment, and discloses a fog gun machine barrel, a fog gun machine and a dust suppression vehicle, the fog gun machine barrel comprises an outer barrel and an inner barrel, the outer barrel is internally provided with a cavity, the inner barrel is arranged in the outer barrel, the inner barrel is internally provided with a cavity and is suitable for installing a fan, the inner wall of the inner barrel is provided with a concave-convex corrugated structure in the axial direction, and an opening in one side of the inner barrel is an air outlet. The concave-convex corrugated structure is arranged on the inner wall of the inner cylinder in the axial direction, so that the area of the inner wall of the inner cylinder can be increased, more refracting surfaces are formed, when the fan works in the inner cylinder, generated noise can be reflected and refracted on the concave-convex corrugated structure, part of the noise is absorbed, and
