Resonance conveyor for hopper discharge - has counterweight and eccentric weight coupled by rubber springs to which excitation force is delivered from both sides

摘要

The resonance conveyor system is particularly for discharging material from hoppers. It has an elastically-suspended conveyor trough and a counter-weight with rotating unbalanced weight coupled together via rubber springs. The excitation force is directed into the rubber springs (1) from the outside on both sides, and then outwards from their centre again. The excitation force can be delivered to the springs, which are preferably rectangular, at an acute angle to their lengthwise axis. The ratio between excitation and working weights can be between 0.5:1 and 1:1, preferably nearly 0.7:1. The size of the rotary unbalanced weight can be adjustable to suit the load.
