Cooling device for nodular cast iron pipe production

The utility model provides a cooling device for nodular cast iron pipe production, and relates to the technical field of cooling devices, the cooling device comprises a box body, a conveyor belt, a limiting block and a supporting rod, a spraying mechanism is arranged at the upper part in the box body, and a rolling mechanism is arranged at the right side in the box body; the conveyor belt drives the nodular cast iron pipe to move from left to right through the limiting block, the water pump is matched with the first pipe to convey water at the bottom of the box body into the spray head to automatically spray the water to the nodular cast iron pipe for cooling, the water stops moving when moving to the area of the rolling mechanism, and the motor, the gear and the linkage shaft are matched to drive the two rotating rollers to rotate in the same direction. The nodular cast iron pipe is continuously driven by the conveying belt to fall into the position between the two rotating rollers, the rotating rollers can
