Abstract

A shaker mechanism used in an agricultural machine, such as sugarcane harvesters and sweet sorghum harvesters. The shaker mechanism is configured for removing mud, dirt and plant remains accumulated in a lower protective tarpaulin of a mounting chassis of conveyor rollers and choppers of the agricultural machine. The shaker mechanism includes at least a bar having ends which are fastened on rotary support bearings. The bar is configured to stand at least partially out from an edge of the bearings forming at least a spare surface for contact with a protective tarpaulin positioned on the chassis of the machine.

First claim

The invention claimed is:

1. A shaker mechanism for an agricultural machine, comprising:
at least two rotary support bearings each having an edge; and
a bar having ends which are fastened to respective ones of the at least two rotary support bearings, the bar fastened to the rotary support bearings so as to stand at least partially out from the edges of the rotary support bearings, the bar forming at least a spare surface for contact with a protective tarpaulin positioned in a chassis of the machine, the protective tarpaulin positioned between the spare surface and a roller of a chassis.

2. The shaker mechanism of claim 1 , wherein the chassis of the agricultural machine comprises a front portion and a rear portion, and wherein the rotary support bearings are configured to be installed in respective openings in the rear portion.

3. The shaker mechanism of claim 1 , wherein the bar is cylindrically shaped and is installed on the rotary support bearings in an eccentric and misaligned condition in relation to a centerline of the rotary support bearings.

4. The shaker mechanism of claim 1 , wherein the bar has an arch shape having a central portion comprising the spare surface for contact with the protective tarpaulin.

5. The shaker mechanism of claim 1 , further comprising a further bar, wherein each bar has an arch shape, wherein the arch shape of each bar is opposite each other, and wherein each bar comprises a central portion forming the spare surface for contact with the protective tarpaulin.

6. The shaker mechanism of claim 1 , wherein the bar has a shape of a sine wave, a triangular segment, or a rectangular segment.

7. The shaker mechanism of claim 1 , further comprising a driver coupled to at least one of the rotary support bearings for driving the at least one of the rotary support bearings.

8. The shaker mechanism of claim 7 , wherein the driver is a hydraulic or electric engine.

9. The shaker mechanism of claim 7 , wherein the driver executes continuous movement of the bar.

10. The shaker mechanism of claim 7 , wherein the driver executes alternate movement of the bar.

11. The shaker mechanism of claim 1 , wherein each of the at least two rotary support bearing comprises rollers.

12. A harvesting machine for harvesting tall and stalky plants, the harvesting machine comprising:
a chassis mounted on tracks or wheels, the chassis comprising an initial section and a final section;
a drive engine;
a cabin for operation and control;
line dividers;
knock-down rollers;
base cutter disks;
a primary cleaning extractor system;
a secondary cleaning extractor system;
an elevator interconnecting the primary and secondary extractor systems;
a plurality of conveyor rollers disposed in the initial and final sections of the chassis;
at least one set of chopper rollers disposed in the final section of the chassis;
a protective tarpaulin disposed below at least one of the plurality of conveyor rollers in the final section of the chassis;
a shaker mechanism disposed beneath the protective tarpaulin, the shaker mechanism comprising:
at least two rotary support bearings each having an edge; and
a bar having ends which are fastened to respective ones of the at least two rotary support bearings, the bar fastened to the rotary support bearings so as to stand at least partially out from the edges of the rotary support bearings, the bar forming at least a spare surface for contact with a protective tarpaulin positioned in a chassis of the machine.

13. The harvesting machine of claim 12 , wherein the chassis, in the final section, comprises respective openings in which the rotary support bearings are installed.

14. The harvesting machine of claim 12 , wherein the bar is cylindrically shaped and is installed on the rotary support bearings in an eccentric and misaligned condition in relation to a centerline of the rotary support bearings.

15. The harvesting machine of claim 12 , wherein the bar has an arch shape having a central portion comprising the spare surface for contact with the protective tarpaulin.

16. The harvesting machine of claim 12 , wherein the shaker mechanism further comprises a further bar, wherein each bar has an arch shape, wherein the arch shape of each bar is opposite each other, and wherein each bar comprises a central portion forming the spare surface for contact with the protective tarpaulin.

17. The harvesting machine of claim 12 , further comprising a driver coupled to at least one of the rotary support bearings for driving the at least one of the rotary support bearings.

18. The harvesting machine of claim 17 , wherein the driver is a hydraulic or electric engine.

19. The harvesting machine of claim 17 , wherein the driver executes continuous or alternate movement of the bar.

20. A harvesting machine for harvesting tall and stalky plants, the harvesting machine comprising:
a chassis mounted on tracks or wheels, the chassis comprising an initial section and a final section;
a plurality of conveyor rollers disposed in the initial and final sections of the chassis;
a protective tarpaulin disposed below at least one of the plurality of conveyor rollers in the final section of the chassis;
a shaker mechanism disposed beneath the protective tarpaulin, the shaker mechanism comprising:
at least two rotary support bearings; and
a bar having ends which are fastened to respective ones of the at least two rotary support bearings and positioned vertically below the protective tarpaulin, wherein the bar is configured to contact the protective tarpaulin during rotation of the bar.
