Abstract
An adjustable scraper structure is attached to a press wheel arm and suspends an adjustable scraper above the press wheel for removing mud buildup above the treads on the tire. The scraper is rotatably adjustable about the rotational axis of the press wheel and the blade pitch is rotatably adjustable about an axis parallel to and removed from the press wheel axis. The pitch or tilt of the scraper blade may be radially aligned with the blade extending perpendicular to a wheel periphery tangent line or the press wheel scraper blade may be inclined somewhat in either direction
Claims14
An adjustable support assembly for an agricultural planter row unit press wheel scraper, comprising;
- a press wheel support arm extending toward the rear of the row unit;
- a press wheel having an axle fixed to the support arm and determining the press wheel axis of rotation;
- an elongated scraper arm pivotably fastened near one scraper arm end for rotation about the press wheel axis of rotation;
- a scraper blade bracket pivotably fastened near another scraper arm end for rotation about an axis displaced from and generally parallel to the press wheel axis of rotation;
- a scraper blade fixed to the scraper blade bracket for removing mud from the press wheel periphery;
- a first fastening mechanism for securing the scraper arm at a preferred angular orientation relative to the press wheel;
- and
- a second fastening mechanism for securing the scraper blade bracket at a preferred angular orientation relative to the scraper arm.
An adjustment arrangement for determining the angular location and orientation of a scraper relative to the outer periphery of a press wheel, comprising:
- a scraper arm pivotably supported near one end on the press wheel axle for limited rotation about the press wheel axle axis;
- a first fastener for fixing the angular position of the scraper arm about the press wheel axis at a selected position;
- a scraper blade pivotably attached to the scraper arm near the other scraper arm end for limited rotation relative to the scraper arm;
- and
- a second fastener for fixing the angular orientation of the scraper blade relative to the scraper arm.
An agricultural planter row unit, comprising:
- a furrow closing arrangement located rearward of furrow opening and seed depositing arrangements for moving soil into a furrow to cover the deposited seeds;
- and
- a soil compacting assembly located rearward of the furrow closing arrangement, including:
- a press wheel support arm extending toward the rear of the row unit;
- a press wheel having an axle fixed to the support arm and determining the press wheel axis of rotation;
- an elongated scraper arm pivotably fastened near one support arm end for rotation about the press wheel axis of rotation;
- a scraper blade bracket pivotably fastened near another scraper arm end for rotation about an axis displaced from and generally parallel to the press wheel axis of rotation;
- a scraper blade fixed to the scraper blade bracket for removing mud from the press wheel periphery;
- a first fastening mechanism for securing the scraper arm at a preferred angular orientation relative to the press wheel;
- and
- a second fastening mechanism for securing the scraper blade bracket at a preferred angular orientation relative to the scraper arm.
