Ground opener with disc scraper mounting
First Claim
1. A scraper assembly for a disc opener comprising:
- a scraper plate defining a scraper edge for contacting and scraping a disc, said scraper plate defining a mounting region remote from said edge;
a scraper plate mount adjacent said mounting region;
a resilient component interposed between said mounting region and said plate mount; and
a spaced pair of fasteners extending through said mounting region to secure said scraper plate and resilient component to said scraper plate mount, said pair of fasteners being located in selected positions in said mounting region relative to said resilient component such that said scraper plate is capable of being tilted or rocked relative to said scraper plate mount in response to forces applied to said scraper plate;
wherein said fasteners are capable of being independently tightened and loosened to vary the degree of compression of said resilient pad, the tightening of both of said fasteners tending to rock said scraper plate about a first axis extending generally parallel to a line extending between said fasteners and to increase the force applied to a disc surface via said scraper edge while differential tightening of said fasteners tends to rock said scraper plate about a second axis so as to affect alignment between said scraper edge and said disc surface.

Abstract
A ground opener unit for a seeding or planting unit includes an arm attachable to an implement frame and a disc rotatably mounted to the arm for forming a furrow in the ground. A scraper assembly includes a scraper plate defining a scraper edge for contacting and scraping a surface of the disc. The scraper plate defines a mounting region remote from the edge. A scraper plate mount secures the scraper plate adjacent the disc and a resilient pad of material is interposed between the plate mounting region and the scraper plate mount. A spaced pair of fasteners extend through the mounting region to secure the scraper plate and resilient pad to the scraper plate mount. The fasteners are located in selected positions in the mounting region relative to the resilient pad such that the scraper plate is capable of being tilted or rocked when said scraper edge encounters irregularities thus assisting the scraper edge to follow the disc surface during use.

6. A ground opener unit for an agricultural planter comprising:
-
an arm attachable to an implement frame;
a disc rotatably mounted to said arm for forming a furrow in the ground;
a scraper assembly including a scraper plate defining a scraper edge for contacting and scraping a surface of said disc, said scraper plate defining a mounting region remote from said edge;
a scraper plate mount for securing said scraper plate adjacent said disc;
a seed tube adjacent said surface of said disc for discharging seeds into a furrow formed by said disc, said seed tube being supported from said arm via a bracket, and said scraper plate mount being fixed to said seed tube;
a resilient component interposed between said mounting region and said scraper plate mount; and
first and second spaced-apart fasteners extending through said mounting region to secure said scraper plate and resilient component to said scraper plate mount, said pair of fasteners being located in selected positions in said mounting region relative to said resilient component such that said scraper plate is capable of being moved relative to said scraper plate mount in response to forces applied to said scraper plate. - View Dependent Claims (7, 8, 9, 10, 11, 12)
