Multi-directional vibration system for fruit harvester - has synchronised eccentric weight generators producing resultant very close to trunk axis

摘要

The multi-directional vibrator mechanism is partic. for harvesting from fruit trees. It comprises a number of vibration generators, synchronised and so arranged that the resultant of the forces they generate is very close to the axis of the trunk etc. The wts. forming each of the generators can be driven by a simple mechanism comprising one or more belts and four pulleys, only one of which is driven from an external source. They can be rotated about the same axes in opposite directions at different speeds very close to each other.
