| 摘要 | A scraper employs a support arm for mounting to a frame of an agricultural implement and a frustoconically bowl-shaped scraper member rotatably supported on the support arm in a position facing the open end of the bowl toward a ground-engaging wheel or disc. Different embodiments disclose unique mounting arrangements, including embodiments where a bearing has its outer race affixed to a closed end wall of the bowl, a bushing is fastened between the inner race of the bearing and a support arm situated outside the bowl to support the bowl in a manner rotatable about the bushing at an axial distance from the support arm, and a separate outer sleeve is disposed around the bushing in a freely rotatable manner to prevent wrapped straw accumulation between the bowl and the support arm during rotating use of the scraper. | ||||||
