Rapid discharging device of metallurgical cooling bed

The utility model relates to the technical field of metallurgical cooling bed equipment, in particular to a quick blanking device of a metallurgical cooling bed, which comprises two groups of supporting legs, two vertical plates are fixedly connected onto the two groups of supporting legs, a driving motor is arranged on one side of one vertical plate, the output end of the driving motor is connected with a driving gear, and the output end of the driving gear is connected with a driving motor. And a connecting rod is arranged between the two vertical plates. When a rolled product is placed on the conveying belt, the motor drives the fan blades to rotate at a high speed, the fan blades drive air vortex in the dust collection box and generate certain negative pressure so as to generate suction force, and therefore residues and waste materials attached to the rolled product can finally enter the dust collection box through the dust collection cover and the dust collection pipeline. Metal residues mixed in the was
