The utility model provides a package child vibrating device of ladle and steel ladle, belongs to the resistant material layer pouring equipment technical field of packet child for the package child is in the stable vibration of resistant material pouring in -process. Its technical scheme is: motor and package child fixed connection, the principal oscillation axle assembles and assembles difference fixed connection on packet child from the vibration axle, motor output shaft and the assembly of principal oscillation axle are connected through belt pulley and driving belt, the assembly of principal oscillation axle is connected with the transmission shaft through the shaft coupling, the transmission shaft is connected with the assembly of follow vibration axle through the shaft coupling, through adjusting the assembly of principal oscillation axle, the eccentric block of installation in assembling from the vibration axle can change the vibration amplitude of packet child, the vibration frequency of packet child can be changed through the accommodate motor rotational speed. The utility model discloses rational in infrastructure, the action is stable, the vibration of package child can realize the frequency conversion rate, become the amplitude vibration, guarantees normally knoing of steel ladle, ladle, guarantees that ladle, the resistant material layer of steel ladle are whole even, fine and close, stable, has apparent economic benefits.
