The inner side of the brush 412 is attached to the outer surface of the steel bar, and the brush 412 is mainly used for cleaning burrs on the outer surface of the steel bar; bristles in the general brush 412 are densely distributed, and when burrs enter the brush 412, the burrs are difficult to clean due to layer-by-layer blocking, so that the burrs are more and more after the bristles grow for a long time, and meanwhile, a plurality of burrs are remained on the upper surface of the steel bar at the left end of the brush 412 and cannot be cleaned at the first time, so that the outer surface of the steel bar is scratched; according to the invention, the bristles are arranged in a spiral shape, and a gap is reserved in the middle, so that when the bristles 412 brush down burrs, the burrs inside the bristles are blown to the outside of the bristles 412 by blowing of the air bag 414, thereby solving the problem of residues inside the bristles 412, and meanwhile, when the bristles are brushed out by the spiral bristles 412, the bristles can give a rotating force to the burrs to spirally fall, thereby preventing the bristles from being remained on the upper surface of the reinforcing steel bar and rolling into the bristles 412 again to scrape the outer surface of the reinforcing steel bar along with the advancement of the reinforcing steel bar.

The specific working process is as follows:

when the device works, the extruded reinforcing steel bar moves to the right and passes through the metal flexible shaft 31, the foam ring 32 fixes the reinforcing steel bar, along with the movement of the reinforcing steel bar, the first bevel gear 402 starts to rotate, the first bevel gear 402 rotates to drive the second bevel gear 403 to rotate, the second bevel gear 403 rotates to drive the third bevel gear 405 to rotate, namely, the rotating rod 406 rotates, the first straight gear 409 rotates to drive the second straight gear 410 to rotate, the brush 412 rotates around the reinforcing steel bar to clean burrs of the reinforcing steel bar, the bristles are spirally arranged, a rotating force is added when the burrs are cleaned, the bristles fall below the upper surface of the reinforcing steel bar to avoid being stopped to damage, because the second straight gear 410 is wider than the first straight gear 409 and the burrs on the surface of the reinforcing steel bar are different in size, the second straight gear 410 moves left and right along the first straight gear 409 while rotating, and when the second straight gear 410 moves to the right, the extrusion ring 413 is forced to extrude the air bag 414, the air bag 414 is extruded to discharge the internal air through the lower end air pipe to blow out and drop the burrs brushed by the brush 412, the internal air falls into the outside through the through hole at the lower end of the protective frame 401 to be convenient for centralized treatment, the reinforcing steel bars after primary treatment of the burrs continuously move rightwards to meet the supporting power conveying mechanism 1, because the rotating speed of the rotating disc 11 of the supporting power conveying mechanism 1 is faster than the moving speed of the reinforcing steel bars, the string rubber strips 15 do back and forth friction motion on the lower surfaces of the reinforcing steel bars, the reinforcing steel bars can rapidly dissipate heat, meanwhile, the burrs on the lower surfaces of the reinforcing steel bars can be rapidly cleaned, when the string rubber strips 15 are fully attached to the lower surfaces of the reinforcing steel bars, the burrs on the lower surfaces of the reinforcing steel bars can be rapidly scraped off by the oblique angles of the absorption grooves 5 arranged in the string rubber strips, namely, the air pressure groove 7 is fully stretched, instantly collapses and straightens due to the elastic action of the rubber at the moment of separation, and the air in the air pressure groove 7 is compressed, so that high-pressure air is sprayed out along the air holes 6 to clean the adhered burrs in the absorption groove 5.
