Patent ID: 8479482

Claim:
A harvesting module comprising: i) twin parallel rotating shafts, each shaft having impact rods configured to rotate in opposite directions in ascending spiral; ii) each of the shafts having a plurality of rings disposed along the shaft to fix the impact rods to the shaft; and iii) said shafts sloped in a way that ends on one side of the twin parallel rotating shafts are closer to the ground than opposite ends of the twin parallel rotating shafts, wherein the impact rods are fixed to the plurality of rings by being pressed by adjacent rings of the plurality of rings; wherein the twin parallel rotating shafts each comprises: an internal cylinder; the rings turning in unison with the internal cylinder; an independent semi-flexible cords fitted to the rings and forming the impact rods; and the internal cylinder having an easily removed end fitting in order to release contact pressure of the adjacent rings and to remove the independent cords; wherein each of the rings comprises: semicircular recessions to fit the impact rods to the sides of the said ring; and projections and second recessions mating one ring to another and preventing separate rotation; and the independent and insertable cords, each one fitted to a semicircular recession and forming a pair of the impact rods.
