Abstract

A ground opening disc scraper assembly comprising: a scraper arm having a proximal end and a distal end, wherein the proximal end is configured for mounting to a support structure; a scraper blade; and a tensioning clip for yieldably mounting the scraper blade to the distal end of the scraper arm.

Claims

1. A ground opening disc scraper assembly comprising:

a scraper arm having a proximal end and a distal end, wherein the proximal end is configured for mounting to a support structure;

a scraper blade; and

a tensioning clip or yieldably mounting the scraper blade to the distal end of the scraper arm.

2. A ground opening disc scraper assembly according to claim 1 wherein the support structure comprises the hub of an opening disc.

3. A ground opening disc scraper assembly according to claim 1 wherein the support structure comprises the frame of a farm implement.

4. A ground opening disc scraper assembly according to claim 1 wherein the scraper arm has a stepped profile, with a transition zone disposed between the proximal end of the scraper arm and the distal end of the scraper arm.

5. A ground opening disc scraper assembly according to claim 1 wherein the scraper arm is rigid.

6. A ground opening disc scraper assembly according to claim 1 wherein the scraper arm is flexible.

7. A ground opening disc scraper assembly according to claim 1 wherein the scraper blade comprises a substantially flat proximal portion and a substantially flat distal portion, wherein the substantially flat proximal portion and the substantially flat distal portion are set at an angle to one another.

8. A ground opening disc scraper assembly according to claim 7 wherein the distal portion of the scraper blade comprises an edge for scraping soil, mud and debris from the surface of an opening disc.

9. A ground opening disc scraper assembly according to claim 1 wherein the scraper blade is rigid.

10. A ground opening disc scraper assembly according to claim 1 wherein the scraper blade is flexible.

11. A ground opening disc scraper assembly according to claim 1 wherein the resilient tensioning clip comprises an elongated flexible body defining an elongated opening and terminating in a pair of ends, wherein the elongated opening is sized to receive a portion of the scraper blade therein.

12. A ground opening disc scraper assembly according to claim 11 wherein the scraper arm comprises a pair of through-holes, and further wherein the ends of the resilient tensioning clip are configured to be received in the pair of through-holes.

13. A ground opening disc scraper assembly according to claim 1 wherein the scraper arm is rigid, the scraper blade is rigid, and the flexing of the scraper blade away from the opening disc is accommodated entirely by the resilient tensioning clip.

14. A ground opening disc scraper assembly according to claim 1 wherein at least one of the scraper arm and the scraper blade is flexible, and the flexing of the scraper blade away from the opening disc is accommodated by the resilient tensioning clip and by one or both of the scraper arm and the scraper blade.

15. A ground opening disc scraper assembly according to claim 14 wherein the majority of the flexing of the scraper blade away from the opening disc is accommodated by resilient tensioning clip.

16. A ground opening disc scraper assembly according to claim 1 wherein the scraper blade is hinged and the resilient tensioning clip is a tension spring.

17. A ground opening disc scraper assembly according to claim 1 further comprising a stop for limiting movement of the scraper blade relative to the scraper arm.

18. A method for removing soil and debris from a ground opening disc, the method comprising:

providing a ground opening disc and a ground opening disc scraper assembly, the ground opening disc scraper assembly comprising;

a scraper arm having a proximal end and a distal end, wherein the proximal end is configured for mounting to a support structure;

a scraper blade; and

a tensioning clip for yieldably mounting the scraper blade to the distal end of the scraper arm; and

positioning the ground opening disc scraper assembly adjacent to the ground opening disc so that the scraper blade yieldably engages the ground opening disc.

19. A ground opening disc scraper assembly comprising:

a scraper arm having a proximal end and a distal end, wherein the proximal end is configured for mounting to a support structure;

a hinged scraper blade mounted to the distal end of the scraper arm; and

a tensioning clip for yieldably biasing the hinged scraper blade against the opening disc.

20. A method for removing soil and debris from a ground opening disc, the method comprising:

providing a ground opening disc and a ground opening disc scraper assembly, the ground opening disc scraper assembly comprising;

a scraper arm having a proximal end and a distal end, wherein the proximal end is configured for mounting to a support structure;

a hinged scraper blade mounted to the distal end of the scraper arm; and

a tensioning clip for yieldably biasing the hinged scraper blade against the opening disc; and

positioning the ground opening disc scraper assembly adjacent to the ground opening disc so that the scraper blade yieldably engages the ground opening disc.
