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.
Claims16
A shaker apparatus for harvesting machine comprising:
- a pair of berry detaching assemblies facing each other, each of said pair of berry detaching assemblies comprising:
- a plurality of vertically-spaced shakers each having a hairpin shape, each of said plurality of vertically-spaced shakers having a pair of branches connected through a curved portion, each of said pair of branches having a first end suitable for connection to an actuation system and a second end suitable for connection to a fixed support, said second end being an active part of the shaker, each of said pair of branches having a means for modifying a degree of stiffness or flexibility of the branch over at least a portion of a length of the branch.
