Abstract
A scraper system for an agricultural machine includes a frame, an opener disc coupled to the frame, a gauge wheel positioned adjacent the opener disc and configured to rotate relative to the frame, and a scraper configured to rotate with the gauge wheel to remove soil or debris from the opener disc. The scraper is ring-shaped, directly coupled to the gauge wheel, and spaced apart from the frame.
Claims19
A scraper system for an agricultural machine comprising:
- an opener disc coupled to a frame;
- a gauge wheel positioned adjacent the opener disc and configured to rotate relative to the frame;
- a scraper configured to rotate with the gauge wheel to remove soil or debris from the opener disc;
- wherein the scraper includes a laterally inwardly facing surface configured to contact the opener disc during forward travel of the agricultural machine;
- wherein the scraper includes a plurality of teeth and each tooth of the plurality of teeth includes two or more radially outwardly facing surfaces facing radially outwardly away from a center of the gauge wheel;
- wherein at least one radially outwardly facing surface of the two or more radially outwardly facing surfaces is concave and another at least one radially outwardly facing surface of the two or more radially outwardly facing surfaces is a convex;
- wherein the at least one radially outwardly facing surface that is concave extends away from the laterally inwardly facing surface.
