Abstract

A harvesting machine having a rotary crop processing unit supported between a pair of spaced side sheets with openings for access to the crop processing unit and a cleaning system therebelow. Molded plastic cover panels extend from the lower edge of the access openings on the side sheet to the crop processing unit to close the access openings. Multiple cover panels are used in each opening to minimize the size of each cover panel for ease in handling and the cover panels are retained by hand manipulated pins or fasteners to remove and install the panels without the use of tools.

Claims

1. A harvesting machine comprising:

a pair of side sheets;

an elongated crop processing unit extending in a fore and aft axial direction between the side sheets and being mounted thereto, the crop processing unit including a housing with a rotor therein to process crop material passing between the housing and the rotor, a lower portion of the housing having openings therein for grain to pass through out of the housing;

a cleaning system between the side sheets and below the housing for receiving and cleaning grain falling from the housing;

one side sheet having an opening therein above the cleaning system to provide access to the housing; and

at least one cover panel removable mounted to and extending from a lower edge of the opening in the side sheet to the housing at a location above the openings in the lower portion of the housing to close the opening.

2. The harvesting machine as defined by claim 1 wherein the at least one cover panel is removably mounted with hand manipulated fasteners whereby the cover panel is removable without the use of tools.

3. The harvesting machine as defined by claim 1 comprising multiple cover panels to close the opening in the side sheet.

4. The harvesting machine as defined by claim 3 wherein the multiple cover panels on the side sheet are identical to one another.

5. The harvesting machine as defined by claim 3 wherein the multiple cover panels are positioned axially adjacent one another and overlap one another at joints between adjacent cover panels.

6. The harvesting machine as defined by claim 1 wherein the cover panel is molded of plastic.

7. The harvesting machine as defined by claim 6 wherein the cover panel has a double wall construction.

8. The harvesting machine as defined by claim 1 wherein both side sheet fame members have at least one said opening therein and at least one said cover panel is provided to close each opening.

9. The harvesting machine as defined by claim 8 wherein multiple cover panels are provided on each side of the harvesting machine with all the cover panels on one side of the harvesting machine being identical to the other cover panels on the one side of the harvesting machine.

10. The harvesting machine as defined by claim 1 wherein the crop processing unit has a threshing section and a separating section and the side sheets have one opening along the threshing section and another opening along the separating section and further comprising multiple cover panels for each opening in each side sheet.

11. A harvesting machine comprising:

a pair of side sheets;

an elongated crop processing unit extending in a fore and aft axial direction between the side sheets and being mounted thereto, the crop processing unit including a housing with a rotor therein to process crop material passing between the housing and the rotor, a lower portion of the housing having openings therein for grain to pass through out of the housing;

a cleaning system between the side sheets and below the housing for receiving and cleaning grain falling from the housing;

one side sheet having an opening therein above the cleaning system to provide access to the lower portion of the housing; and

multiple cover panels removably mounted in the opening to close the opening to prevent access to the lower portion of the housing and the cleaning system, the multiple panels extending from a lower edge of the opening in the side sheet to the housing at a location above the openings in the lower portion of the housing.

12. The harvesting machine as defined by claim 11 further comprising one said opening in both side sheets and multiple cover panels in each opening.

13. The harvesting machine as defined by claim 12 further comprising two of the openings in each of the side sheets and multiple cover panels in each of the openings.

14. The harvesting machine as defined by claim 13 wherein the cover panels in the openings in one side sheet are identical.

15. The harvesting machine as defined by claim 11 wherein the multiple cover panels are positioned axially adjacent one another and overlap one another at joints between adjacent cover panels.

16. The harvesting machine as defined by claim 11 wherein the multiple cover panels are removably mounted with hand manipulated fasteners whereby the cover panels are removable without the use of tools.

17. The harvesting machine as defined by claim 11 wherein the cover panels are molded of plastic.

18. The harvesting machine as defined by claim 17 wherein the cover panels have a double wall construction.

19. A harvesting machine comprising:

a pair of side sheets;

an elongated crop processing unit extending in a fore and aft axial direction between the side sheets and mounted thereto, the crop processing unit including a rotor housing with a rotor therein to process crop material passing between the housing and the rotor, the housing having threshing section and a separating section rearward of the threshing section;

the housing being mounted to the side sheets through a front bulkhead at a forward end of the threshing section, an intermediate bulkhead between the threshing and separating sections and a rear bulkhead rearward of the separating section;

a cleaning system between the side sheets and below the housing for receiving and cleaning grain falling from the housing;

the side sheets having an access opening to the threshing section of the housing extending between the front and intermediate bulkheads and an access opening to the separating section extending between the intermediate and rear bulkheads; and

multiple cover panels removably mounted in the access openings to close the openings and prevent access to the crop processing unit therethrough, the multiple cover panels extending from a lower edge of the opening in the side sheet to the housing at a location above the openings in the lower portion of the housing.
