The utility model discloses a molten iron sampler. The molten iron sampler comprises a device body, according to the device, the connecting block is in threaded connection with the screw rod, meanwhile, the bottom of the device body is connected with the connecting
pipe through the first threaded groove, then the connecting
pipe is placed in molten iron, meanwhile, the telescopic rod in the clamping groove rotationally stretches out, auxiliary supporting is conducted on the device body through the telescopic rod, and therefore the operation difficulty of operators is reduced; meanwhile, the
rotating disc is rotated, the
rotating disc drives the molten iron through the connecting block and the screw rod, then the molten iron is discharged through the discharging opening, and the screw rod and the connecting
pipe with different lengths are replaced, so that the molten iron with different depths can be conveniently sampled, an operator can conveniently operate with one hand, the operation is simple, the operation range is small, and labor is saved; and meanwhile, the other hand of the operator can be vacated to improve the safety of the operator, and the practicability is high.
