Abstract
Shaker with adjustable stiffness for harvesting machines, especially grape harvesters, includes two berry detaching assemblies, facing each other. Each assembly includes a plurality of vertically spaced out flexible shakers, having the general shape of a hairpin and two branches connected through a curved portion. The end of one of these branches, the activation branch, connects to an actuation system while the end of the other branches connects to a fixed support. The activation branch is equipped with a mechanism to modify the degree of stiffness or flexibility of the branches over at least a portion of length, and thereby, to adjust the degree of stiffness or flexibility of the shaker assembly.
