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.

Claims (43)

1. 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.

2. The harvesting module ( 27 ) according to claim 1 , wherein the rotation of the twin shafts ( 1 ) are driven by an electric motor ( 7 ).

3. The harvesting module 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.

4. The harvesting module according to claim 1 , wherein forward ends of the twin parallel rotating shafts are configured to be lower to the ground than rearmost ends, in a travel direction.

5. The harvesting module according to claim 1 , further comprising:

a grain transport and cleaning system comprising a blower and an air duct located under the plane of the shafts, a duct for conveying grains and chaff, and an inertial chamber.

6. The harvesting module according to claim 1 , further comprising:

a pneumatic system preventing loss of grains with applying an airflow at the ends of the twin parallel rotating shafts closer to the ground.

7. The harvesting module according to claim 4 , further comprising:

a pneumatic system preventing loss of grains by applying an airflow at the ends of the twin parallel rotating shafts closer to the ground.

8. The harvesting module according to claim 1 , further comprising:

a defoliant system mounted in front of the harvesting module.

9. 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 fitted to each ring and kept in place 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

said internal cylinder having an easily removed end fitting in order to release contact pressure of the adjacent the 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.
