Adjustable scraper assembly for planter gauge wheels
First Claim
1. An adjustable scraper assembly for planter gauge wheels, comprising:
- a support rod having a first end attached to a planter and a second end spaced from said first end;
a first clamp structure clamped to said second end of the support rod, said first clamp structure allowing a sliding adjustment along said second end of said support rod and a pivotal adjustment about a first axis of rotation comprising an axis of said second end of said support rod;
a protrusion member protruding from said first clamp structure in a nonparallel direction relative to said second end of said support rod;
a second clamp structure attached to said first clamp structure, said second clamp structure allowing a pivotal adjustment about a second axis of rotation comprising an axis of said protrusion member; and
a scraper blade attached to said second clamp structure, said scraper blade being attached to said second clamp structure with a threaded fastener that allows pivotal adjustment about a third axis of rotation comprising an axis of the threaded fastener;
said first, second and third axes of rotation are nonparallel with each other and allow adjustment of said scraper blade about three nonparallel axes of rotation.

Abstract
An adjustable scraper assembly for clearing mud and trash from the gauge wheel tires of an agricultural planter includes a support rod connected to the planter, a clamp assembly attached to the support rod, and a scraper blade attached to the clamp assembly. The clamp assembly has first and second clamping blocks that function together to allow pivotal adjustment of the scraper blade relative to the support rod about three nonparallel axes of rotation and sliding adjustment along at least one linear direction relative to the support rod. The support rod is attached to the planter using a third clamping block clamped to the hub of a gauge wheel arm. The third clamping block can be used to provide an additional adjustment of the support rod relative to the gauge wheel arm.

8. An adjustable scraper assembly for planter gauge wheels, comprising:
-
a support structure adapted to be attached to a planter; a clamp assembly attached to said support structure; and a scraper blade attached to said clamp assembly for scraping an outer surface of a planter gauge wheel tire; said clamp assembly comprising means for pivotally adjusting the scraper blade about three nonparallel axes of rotation and for slidably adjusting the scraper blade in at least one linear direction relative to said support structure; wherein said support structure comprises a support rod having a first end adapted to be attached to a planter and a second end spaced from said first end; and wherein said means for adjusting the scraper blade comprises a first clamp structure clamped to said second end of the support rod for allowing sliding adjustment along said support rod and pivotal adjustment about said support rod, a second clamp structure attached to said first clamp structure for allowing pivotal adjustment about an axis extending in a nonparallel direction relative to the second end of said support rod, and said scraper blade attached to said second clamp structure with a threaded fastener that allows pivotal adjustment about an axis of the threaded fastener. - View Dependent Claims (9, 10, 11, 12)
