ABSTRACT:
A vibration device for a silo for bulk material having a funnel-shaped delivery outlet comprises an elastically suspended support carrying a jolting motor and provided with downwardly extending guide wings in the configuration of a rosette of blades extending into the outlet passage and a cage surrounding the guide wings and formed with downwardly converging walls parallel to the walls of the delivery funnel. The cage may be provided with an array of downwardly extending rods and is supported against the sides or walls of the funnel by elastic members or buffers, the entire assembly being elastically suspended in the funnel, e.g. by tension springs. Between the jolting motor and the cage, there are provided longitudinally and torsionally elastic spring elements so that the assembly comprises two independently vibrating masses set into vibration by the jolting motor.
