Dispositions introduced to rotating shaft, impact rod harvester

Abstract

Provided is a harvesting module including twin parallel rotating shafts. The rotating shafts each have impact rods that are configured to rotation in opposite directions. The shafts are sloped so that one end of the shafts is closer to the ground than another end of the shafts. The rods are fixed to the shafts in a spiral formation using a series of self locking rings fitted over the shafts.

1 . Harvesting module comprising:
 i) twin parallel rotating shafts ( 1 ) having impact rods rotating in opposite directions in descending spiral;   ii) said shafts are sloped in a way that their rearmost ends are closer to the ground than their forward ends; and   (iii) the existence of a semicircular metal casing preventing contact of the threshed plant stalks with the shafts along the final half of the said thresher shafts, linked to the two air conveyor ducts.   
     
     
         2 . Harvesting module ( 27 ) according to  claim 1 , further comprising a grain transport and cleaning system comprising a blower ( 2 ) and an air duct ( 12 ) located under the plane of the thresh shafts ( 1 ), duct for conveying grains and chaff ( 9 ) and inertial chamber ( 4 ). 
     
     
         3 . Harvesting module ( 27 ) according to  claim 1 , further comprising a pneumatic system preventing loss of grains with ascending airflow at the inferior end of the twin shafts ( 1 ). 
     
     
         4 . Harvesting module ( 27 ) according to  claim 1 , wherein the rotation of the twin shafts ( 1 ) are driven by an electric motor ( 7 ). 
     
     
         5 . Harvesting module ( 27 ) according to  claim 1 , having a power source provided by an electric generator ( 33 ) coupled to a regular farm tractor's power take-off (PTO) shaft. 
     
     
         6 . A harvesting module according to  claim 1 , wherein the twin parallel rotating shafts each comprises:
 an internal cylinder, having a plurality of rings disposed along its extension;   the rings turning in unison with the internal cylinder;   the independent semi-flexible cords fitted to the rings and forming the impact rods; and   said internal cylinder having an easily removed end fitting in order to release contact pressure of the adjacent rings and to remove the independent cords.   
     
     
         7 . A harvesting module according to  claim 1 , wherein each of the rings comprises:
 semicircular recessions to fit the impact rods to the sides of the said ring;   projections and seconds recessions mating one ring to another and preventing separate rotation; and   independent and insertable semi-flexible cords, each one fitted to a semicircular recession and forming a pair of impact rods.
