Cleaner for tined wheels
DCFirst Claim
1. A cleaning device for removing debris from the teeth of a wheel having a plurality of spaced apart teeth on the periphery, the wheel mounted on a framework on an axis to permit rotation of said wheel during forward movement of said framework so that the teeth penetrate the soil as the wheel rotates comprising:
- a flat unitary plate member of wear-resistant material having a first portion;
said axis of said wheel extending through said first portion of said member so that said member is rotatably and adjustably mounted at a distance from said wheel about the axis of said wheel, said members secured in a predetermined circumferential relationship with said wheel;
a generally rectangular second portion of said member angled from said first portion in the axial direction toward the adjacent face of said wheel, said second portion adjacent said teeth on said wheel; and
said second portion including an edge of one side of said second portion positioned on a chord of said wheel, whereby as said wheel rotates said second portion and said edge of said second portion will eject material collected between said teeth.

Abstract
This invention provides an improved apparatus for maintaining tooth rotating wheels, which are used to penetrate the soil either as a cultivating apparatus, a row cleaning apparatus, or as closing apparatus for row planters free of mulch, trash, dirt and/or rocks. By removing the debris from the space between the teeth on the wheel, the wheel can penetrate the soil to a controlled or desired depth as set by the operator. Debris between the wheels can limit the depth of penetration by the formation of a solid or semi-solid mass generally resembling of variable rim diameter. The wheels may be driven by a power mechanism or may be rotated by the penetration in the ground and the forward motion of a propulsion unit.
The toothed wheel is kept clean of debris, thereby allowing accurate depth penetration as determined by conditions and requirements.
