    • According to the invention, a vibratory apparatus is provided having a deck resiliently mounted relative to a surface bearing the vibratory apparatus, a clamp support for a casting on the deck, and a piston freely movably mounted relative to the deck. Vibration imparting structure vibrates the deck to shake out and to loosen foreign matter adhered to the casting supported on the deck and simultaneously reciprocates and ricochets the piston relative to the deck to further shake out and loosen foreign matter on the casting. A hammer plate is provided on the deck in the path of the piston. As the vibration imparting structure is operated, the piston is intermittently forcibly driven against the hammer plate to set up a different frequency of vibration than the frequency of the primary vibratory apparatus which enhances the shake out and cleaning function of the structure.
    • 根据本发明,提供了一种振动装置,其具有相对于承载振动装置的表面弹性安装的甲板,用于在甲板上铸造的夹具支撑件和相对于甲板自由移动地安装的活塞。 振动赋予结构使甲板振动摇晃,松动附着在甲板上的铸件上的异物,同时使活塞相对于甲板往复运动并使活塞进一步摆动并松动铸件上的异物。 在活塞的路径上的甲板上设置锤板。 当振动赋予结构被操作时,活塞被间歇地强制地驱动抵靠锤板,以建立与主振动装置的频率不同的振动频率,这增强了振动和结构的清洁功能。
