covering and flattening the protective material on the sweeping surface of the support plate;
rotating and extending the support plates so that the plurality of support plates form an umbrella-shaped support for the protective material;
the protective material preferentially contacts the top surface of the surrounding rock, and the supporting plate swings;
and scraping the protective materials gradually from the middle to the two sides through the sweeping surface to ensure that the protective materials are attached to the surrounding rock.
