Vibratory grape-harvesting machine - has passage formed by bars whose supports reciprocating with amplitude increasing upwards from zero at ground level

摘要

The vibratory grape-harvesting machine has two horizontal parallel bars positioned on opposite sides of the vines, and secured to vertical supports at one end. The supports (2, 3) reciprocate with zero amplitude at ground level, the amplitude increasing towards the top so that they interleave as the vine bends sideways. The bars (10, 11) can be adjustable for angle on their supports, so that their free ends form an envelope around the vine.
