Abstract
A vibratory conveying device comprise an elongated trough for transporting materials, and a base underlying the trough. A plurality of elongated leaf springs support the trough on the base, with a vibratory drive system operatively connected to the base for effecting vibratory movement of the trough. Economical manufacture and efficient maintenance are facilitated by configuring the base so that it comprises a pair of sheet-like base side members, with a laterally extending drive support member extending therebetween. In the preferred form, the drive support member is detachably connected to the base side members with suitable mechanical fasteners. In turn, a pair of rotary vibratory drives of the drive system are removably mounted on respective opposite sides of the drive support member by a plurality of threaded mechanical fasteners.
