VIBRATORY CONVEYOR

摘要

A vibratory conveying apparatus (10) for moving materials, comprising: a base (12) ; a conveying member (18) supported from the base by at least one resilient support (34) ; a drive (38) arranged to excite said conveying member into vibration; and an absorbing mass (40) supported from the base by at least one resilient support (42) such that movement of the absorbing mass is substantially parallel to that of the conveying member, and that a line passing through the absorbing mass' centre of gravity (44) and the conveying member's centre of gravity (36) is substantially perpendicular to the at least one resilient conveying member support, wherein the natural frequency of the absorbing mass is arranged to be substantially equal to the natural frequency of the conveying member, or a multiple thereof, whereby when the conveying member is excited into vibration by the drive, the absorbing mass vibrates substantially in phase opposition to the conveying member, resulting in the absorption of energy from the base .
