[0002] During the snow season, snow accumulation will affect people's travel and production. At present, the adverse effects of snow accumulation are usually reduced or eliminated by cleaning. At present, the more convenient way to clean is to use a snowplow for cleaning operations. Snowplows usually remove snow by rotating a roller-shaped brush. The surface of the roller brush is covered with brush blades. Since the brush blades are in direct contact with the ground to remove the snow, the brush blades are severely worn. When the brush blade wear seriously affects the cleaning efficiency, the roller brush needs to be replaced. However, due to the space limitations of the snowplow, the entire roller brush is usually removed from the snowplow for replacement. The existing method of removing the roller brush is to lift the roller brush for replacement by multiple people. The weight of the roller brush is usually around 500-600 kilograms, and due to the large size of the roller brush itself, the operation process of replacing the roller brush is not only time-consuming and labor-intensive, but also poses a great safety risk.
