Abstract

An agricultural tillage implement has a disk frame assembly connected to a pull hitch extending in a travel direction with frame members extending generally laterally with respect to the travel direction. At least one disk blade is connected to and supported by the frame members to till soil over which the agricultural tillage implement traverses. A disk scraper mounting member is connected to at least one frame member. A channel shaped disk scraper is connected to the disk scraper mounting member using a bolted joint connection. The channel shaped disk scraper has a square mounting end adjoining an inner perpendicular surface of the disk scraper mounting member. The channel shaped disk scraper is operable to scrape residue from the at least one disk blade and deflect it away from the travel direction.

First claim

What is claimed is:

1. A disk scraper assembly for an agricultural tillage implement, said agricultural tillage implement having a disk frame assembly connected to a pull hitch extending in a travel direction, the disk frame assembly having at least one frame member extending generally laterally with respect to the travel direction, the disk assembly comprising:
at least one pair of disk blades connected to and supported by the at least one frame member, each disk blade operably connected to and supported by the at least one frame member so that the at least one pair of disk blades are positioned to till soil over which the agricultural tillage implement traverses;
at least one disk scraper mounting member connected to the at least one frame member; and
at least one disk scraper connected to the at least one disk scraper mounting member using a bolted joint connection, the at least one disk scraper having a mounting end connected to a surface of the at least one disk scraper mounting member, the at least one disk scraper positioned and extending between the at least one pair of disk blades, the at least one disk scraper operable to simultaneously scrape residue from one surface of each disk blade of the at least one pair of disk blades and deflect the residue away from the travel direction, wherein a scraping end of the at least one disk scraper is configured to extend no lower than a central shaft which extends through each disk blade,
wherein the at least one disk scraper includes a flat portion extending from the mounting end to the scraping end which is formed in a flat plane,
wherein the at least one disk scraper mounting member is adjustable to adjust an angle of the at least one disk scraper, and
wherein the at least one disk scraper includes two spaced-apart side wails connected to the at least one disk scraper at the mounting end, the two spaced-apart side walls formed to extend along the at least one disk scraper to taper and end near the scraping end such that the scraping end extends therebeyond in the flat plane.

2. The disk scraper assembly of claim 1 , wherein:
each disk blade includes a convex surface near an edge on one side, and a concave surface near the edge on and opposite side, and the at least one disk scraper is positioned near the convex surface of one disk blade and near the concave surface of the other disk blade to scrape residue extending therefrom.

3. The disk scraper assembly of claim 1 , wherein:
the at least one disk scraper mounting member is connected to the at least one frame member through at least one disk blade bearing hanger assembly, the at least one disk blade bearing hanger assembly further functioning to rotatably connect the at least one pair of disk blades to the at least one frame member.

4. The disk scraper assembly of claim 1 , wherein:
the at least one disk scraper mounting member is connected to the at least one frame member so that the at least one disk scraper is adjustable relative to the at least one pair of disk blades.

5. The disk scraper assembly of claim 4 , wherein:
the mounting end of the at least one disk scraper is connected to an adjoining inner perpendicular surface of the at least one disk scraper mounting member.

6. The disk scraper assembly of claim 1 , wherein:
the at least one pair of disk blades further comprises at least two gangs, each gang including at least one pair of disk blades, and
wherein the at least one disk scraper mounting member further comprises a disk scraper mounting member associated with each pair of disk blades on each gang.

7. The disk scraper assembly of claim 1 , wherein:
the at least one frame member further comprises at least two frame members; and
the at least one disk scraper mounting member further comprises a disk scraper mounting member associated with each of the at least two frame members.

8. The disk scraper assembly of claim 1 , wherein:
the agricultural tillage implement is one of a multi-section field disk ripper, a disk harrow, a disk ripper, an in-line ripper, a strip-till, and a vertical tillage implement using disk blades.

9. The disk scraper assembly of claim 1 , wherein the scraping end of the at last one disk scraper is positioned to contact the residue when the implement is traveling in the travel direction, and wherein the at least one disk scraper is configured to be positioned such that the scraping end is positioned near a central shaft which extends through each disk blade in order to move residue away from the central shaft.
