VIBRATING-DEVICE-HAVING HOPPER

摘要

PROBLEM TO BE SOLVED: To provide a vibrating-device-having hopper capable of preventing the hopper from being clogged with raw material by efficiently vibrating a hopper body. SOLUTION: The vibrating-device-having hopper 1 comprises a hopper body 2 capable of storing a raw material therein and having a discharging opening in its lower part for the raw material, and a vibrating device 3 capable of vibrating walls forming the hopper body 2. The vibrating device 3 vibrates the walls by slightly shaking it at resonance frequency that causes the walls 21 of the hopper body 2 to resonate. COPYRIGHT: (C)2008,JPO&INPIT
