Shaker mechanism for grape harvester - has vertically spaced horizontal flexible blades which are reciprocated in vertical plane by crank mechanism

摘要

The machine has assemblies of flexible blades which are arranged one above the other. They move in a vertical plane such that they move upwards when nearest the vines and lower when furthest from the vines. The assemblies are carried by symmetrical housings on eith side of the vines. The blades are carried by supports which can pivot rearwardly against springs due to resistance.
