Abstract

A universal scraper for use with an opening disc, the universal scraper comprising an elongated body having a first end and a second end, the first end being adapted to mount to an axle, and the second end being adapted to receive a scraper blade, wherein the elongated body is sized and shaped so that when the first end of the elongated body is attached to an axle and a scraper blade is mounted to the second end of the elongated body, the scraper blade is presented in scraping disposition to the opening disc.

Claims

1. A universal scraper for scraping an opening disc, wherein the opening disc rotates around an axle having a longitudinal axis, the universal scraper comprising:

an elongated body having a first end and a second end, wherein the first end is mounted to the axle of the opening disc, and the second end receives a scraper blade for engagement against the opening disc, wherein the first end of the elongated body is adjustably lockable to the axle of the opening disc at a selected angle to the longitudinal axis of the axle of the opening disc, and further wherein the elongated body holds the scraper blade so as to be fixed against rotation relative to the opening disc during operation of the scraper blade.

2. A universal scraper according to claim 1 wherein the first end of the elongated body is adapted to mount to an axle supporting the opening disc.

3. A universal scraper according to claim 1 wherein the first end of the elongated body is adapted to mount to an axle supporting a gauge wheel.

4. A universal scraper according to claim 1 wherein the first end of the elongated body is mounted to an adapter secured to the axle of the opening disc.

5. A universal scraper according to claim 4 wherein the first end of the elongated body is clamped to the adapter.

6. A universal scraper according to claim 4 wherein the first end of the elongated body comprises two segments separated by a gap, and further wherein the two segments are adjustably movable relative to one another so as to clamp the elongated body to the adapter.

7. A universal scraper according to claim 1 wherein the axle of the opening disc comprises a threaded stud extending from a frame, and further wherein the adapter is secured to the threaded stud with a nut.

8. A universal scraper according to claim 1 wherein the axle comprises an axle bolt secured in a hole in a frame, and further wherein the adapter is secured to the axle by the head of the axle bolt.

9. A universal scraper according to claim 1 wherein the elongated body is fixed in length.

10. A universal scraper according to claim 1 wherein the elongated body is adjustable in length.

11. A universal scraper according to claim 1 further comprising a spanning body having a first end and a second end, the first end of the spanning body mounted to the elongated body, and the second end of the spanning body receiving a second scraper blade.

12. A universal scraper according to claim 11 wherein the spanning body spans a width of the opening disc so that the scraper blade and the second scraper blade scrape opposing sides of the same opening disc.

13. A universal scraper according to claim 12 wherein the spanning body comprises one of a J-shaped configuration and a U-shaped configuration.

14. A universal scraper according to claim 13 wherein the first end of the spanning body is mounted to the elongated body by inserting the first end of the spanning body into a hole.

15. A universal scraper according to claim 14 wherein the hole is formed in the elongated body.

16. A universal scraper according to claim 14 wherein the hole is formed in a member which is attached to the elongated body.

17. Apparatus for opening ground, the apparatus comprising:

a frame;

an opening disc rotatably mounted to the frame on an axle having a longitudinal axis; and

a universal scraper for scraping the opening disc, the universal scraper comprising;

an elongated body having a first end and a second end, wherein the first end is mounted to the axle of the opening disc, and the second end receives a scraper blade for engagement against the opening disc, wherein the first end of the elongated body is adjustably lockable to the axle of the opening disc at a selected angle to the longitudinal axis of the axle of the opening disc, and further wherein the elongated body holds the scraper blade so as to be fixed against rotation relative to the opening disc during operation of the scraper blade.

18. A method for opening ground, the method comprising:

providing a frame, an opening disc rotatably mounted to the frame on an axle having a longitudinal axis, and a universal scraper for scraping the opening disc, the universal scraper comprising an elongated body having a first end and a second end, wherein the first end is mounted to the axle of the opening disc, and the second end receives a scraper blade for engagement against the opening disc, wherein the first end of the elongated body is adjustably lockable to the axle of the opening disc at a selected angle to the longitudinal axis of the axle of the opening disc, and further wherein the elongated body holds the scraper blade so as to be fixed against rotation relative to the opening disc during operation of the scraper blade; and

moving the opening disc through the ground.

19. A universal scraper for scraping an opening disc, wherein the opening disc rotates around an axle having a longitudinal axis, the universal scraper comprising:

an elongated body having a first end and a second end, wherein the first end is mounted to the axle of the opening disc, and the second end receives a scraper blade, and further wherein the scraper blade is presented in fixed, scraping disposition to the opening disc during operation of the scraper blade; and

a spanning body having a first end and a second end, the first end of the spanning body mounted to the elongated body, and the second end of the spanning body receiving a second scraper blade;

wherein the spanning body spans a width of the opening disc so that the scraper blade and the second scraper blade scrape opposing sides of the same opening disc;

wherein the spanning body comprises one of a J-shaped configuration and a U-shaped configuration;

wherein the first end of the spanning body is mounted to the elongated body by inserting the first end of the spanning body into a hole;

wherein the hole is formed in the elongated body.
