Abstract

A scraper for mounting to a tool bar of a farm implement having at least one rotating disk for tilling soil, including a support mounted to the tool bar and a shaft pivotally attached to and extending from the support where the shaft has a central axis. A scraper blade is rotatably attached to an end of the shaft and the scraper blade comprises a perimeter wherein the shaft pivots to rotatably engage a side surface of the rotating disk to prevent soil from accumulating on the side surface and prevents debris from accumulating between the side surface and the scraper blade.

Claims

1. A scraper for mounting to a tool bar of a farm implement having a rotating disk for tilling soil, the scraper comprising:

a support mounted to the tool bar, the support comprising a shank having a first end and a second end and an upper stop and a lower stop in communication with the shank, the shank being non-movably attachable to the tool bar proximate a first end of the shank;

a shaft extending from the shank and having a central axis, a first end and a second end, the shaft pivotally attached to the shank proximate the second end of the shank wherein the shaft is positioned between the upper stop and the lower stop such that the upper stop and the lower stop limit the pivotal movement of the shaft; and

a scraper blade rotatably attached to the shaft proximate the second end of the shaft and wherein the scraper blade comprises a perimeter and wherein the shaft pivotally moves while the rotating disk is rotating to rotatably engage the perimeter of the scraper blade with a side surface of the rotating disk to remove soil and debris that accumulates on the side surface.

2. The scraper of claim 1 and wherein the support further comprises:

left and right plates attached to opposite sides of the shank proximate the second end of the shank wherein the left and right plates define a slot there between.

3. The scraper of claim 2 and wherein the shaft is positioned within the slot.

4. The scraper of claim 3 and wherein the shaft comprises an aperture proximate the first end that aligns with a first set of apertures in the left and right plates such that a securing mechanism is positioned through the apertures to pivotally attach the shaft to the shank.

5. The scraper of claim 3 and further comprising the upper stop and the lower stop positioned within the slot.

6. The scraper of claim 1 and wherein a position of the upper stop is adjustable.

7. The scraper of claim 1 and further comprising a bearing attached to the second end of the shaft for rotating the scraper blade about the shaft.

8. The scraper of claim 1 and wherein the scraper blade comprises a circular perimeter and wherein the scraper blade rotates clockwise or counterclockwise in the path of least resistance when contacting the rotating disk.

9. The scraper of claim 1 and wherein the support further comprises a mounting bracket secured to the shank wherein the mounting bracket attaches to the tool bar.

10. A farm implement comprising:

at least one rotating disk for tilling soil;

a tool bar proximate the at least one rotating disk; and

at least one scraper attached to the tool bar, the scraper comprising;

a support mounted to the tool bar, the support comprising a shank having a first end and a second end and an upper stop and a lower stop in communication with the shank, the shank being non-movably attached to the tool bar proximate a first end of the shank;

a shaft extending from the support and having a central axis, a first end and a second end, the shaft pivotally attached to the shank proximate the second end of the shank wherein the shaft is positioned between the upper stop and the lower stop such that the upper stop and the lower stop limit the pivotal movement of the shaft; and

a scraper blade rotatably attached to the shaft proximate the second end of the shaft and wherein the scraper blade comprises a perimeter and wherein the shaft pivotally moves while the rotating disk is rotating to rotatably engage the perimeter of the scraper blade with a side surface of the rotating disk to remove soil and debris that accumulates on the side surface.

11. The farm implement of claim 10 and wherein the support further comprises:

left and right plates attached to opposite sides of the shank proximate the second end of the shank wherein the left and right plates define a slot there between.

12. The farm implement of claim 11 and wherein the shaft is positioned within the slot.

13. The farm implement of claim 11 and wherein the shaft comprises an aperture proximate the first end that aligns with a first set of apertures in the left and right plates such that a securing mechanism is positioned through the apertures to pivotally attach the shaft to the support.

14. The farm implement of claim 12 and further comprising the upper stop and the lower stop positioned within the slot.

15. The farm implement of claim 14 and wherein a position of the upper stop is adjustable.

16. The farm implement of claim 10 and further comprising a bearing attached to the second end of the shaft and the scraper blade for rotating the scraper blade about the shaft.

17. The farm implement of claim 10 and wherein the scraper blade comprises a circular perimeter and wherein the scraper blade rotates clockwise or counterclockwise in the path of least resistance when contacting the rotating disk.

18. The farm implement of claim 10 and wherein the support comprises a mounting bracket secured to the shank wherein the mounting bracket attaches to the tool bar.

19. The farm implement of claim 10 and wherein the at least one disk includes a concave side surface.

20. A scraper for mounting to a tool bar of a farm implement having a rotating disk for tilling soil, the scraper comprising:

a support mounted to the tool bar, the support comprising;

a shank having a first end and a second end wherein the shank is non-movably attachable to the tool bar proximate the first end of the shank;

a plate attached to the shank proximate the second end of the shank; and

an upper stop attached to the plate and a lower stop attached to the plate;

a shaft extending from the shank and having a central axis, a first end and a second end, the shaft pivotally attached to the shank proximate the second end of the shank wherein the shaft is positioned between the upper stop and the lower stop such that the upper stop and the lower stop limit the pivotal movement of the shaft; and

a scraper blade rotatably attached to the shaft proximate the second end of the shaft and wherein the scraper blade comprises a perimeter and wherein the shaft pivotally moves while the rotating disk is rotating to rotatably engage the perimeter of the scraper blade with a side surface of the rotating disk to remove soil and debris that accumulates on the side surface.
