The front end of the slope cover plate 4 is penetrated and embedded with a filter screen 5 at the lateral end surface. The mesh diameter of the filter screen 5 is one millimeter. The outer surface of the filter screen 5 is treated with anti-corrosion. A side triangular covering strip 6 is provided on the front side of the slope cover plate 4. The side triangular covering strip 6 is fixedly connected to the front end of the slope cover plate 4 by welding. A partition strip 12 is provided at the bottom end of the side triangular covering strip 6 at the front edge. The partition strip 12 is connected to the bottom end of the side triangular covering strip 6 by adhesive. The partition strips 12 are arranged at equal intervals, and the partition strips 12 do not change in shape due to the influence of airflow.
