The cleaning component includes a steel strand 1, the number of which is 23, and the length of each strand is 60 cm. The material of the steel strand 1 is easy to obtain, and the effect of cleaning loose slag is good. Steel plates 2 are fixed above and below the steel strand 1. The size of the steel plate 2 is 80 cm long, 24 cm wide, and 1.6 cm thick. The steel plate 2 is used to fix the steel strand 1.

[0025] There are two steel plates 2, and the upper and lower steel plates 2 sandwich the steel strand 1 in the middle to form a broom head. There are 14 φ20 holes on the steel plate 2. On the long side of the steel plate 2, 38mm away from the edge of the long side, starting from one short side, drill a φ20 hole at 30mm, 133mm, 158mm, 160mmm, 158mm, and 133mm respectively; drill a φ20 hole at the center of the short distance of 30mm from the edge of the short side on both sides; a total of 14 φ20 holes are used to pass bolts. The steel plate 2 and the steel strand 1 are fixed by a bolt group 3, which includes bolts and nuts. The number of bolt groups 3 is 14 sets, and the pitch is M20. The bolt connection method of the bolt group 3 can be easily disassembled. The bolts and nuts can be disassembled using a wrench or a torque wrench, which is convenient for maintenance and replacement.
