Scraper blade assembly for planter gauge wheels

摘要

A scraper assembly for removing mud and moist soil from the gauge wheels of an agricultural planter includes a support rod attached to a hub of a gauge wheel arm, a clamp structure attached to an end portion of the support rod, and a scraper blade attached to the clamp structure. An axis of the end portion of the support rod is approximately perpendicular to and intersects with an axis of rotation of the gauge wheel. The scraper blade is mounted approximately perpendicular to the outer surface of the gauge wheel and is angled approximately 45 degrees from the sides of the gauge wheel. The scraper blade has a curved profile along its length that substantially matches an outer profile of the outer surface of the gauge wheel when the scraper blade is properly adjusted.

主权项

1. A scraper assembly in combination with a planter gauge wheel having an axis of rotation and an outer circumferential surface for engaging the ground, the scraper assembly comprising:
a mounting bracket; a support rod having a first end portion attached to said mounting bracket and a second end portion having an axis that is approximately perpendicular to and intersects with the axis of rotation of the gauge wheel; a clamp structure attached to said second end portion of said support rod, said clamp structure having a tightened condition in which said clamp structure is fixed to said second end portion of said support rod and an adjustment condition in which said clamp structure is adjustable linearly along and rotatably about said second end portion of said support rod; and a scraper blade attached to said clamp structure by a fastener that allows pivotal adjustment about an axis of the fastener, said scraper blade having a scraping edge positioned close to or against the outer surface of the gauge wheel.
