Abstract
Rake wheels for a raking apparatus for gathering crop material into a windrow. The rake wheel may include a center hub and a plurality of tines that extend outward from the center hub. In some embodiments, the rake wheel includes support members such as disks for securing and limiting circumferential and/or axial movement of the tines of the rake wheel.
Claims13
A rake wheel for gathering crop material into a windrow, the rake wheel comprising:
- a center hub having a rotational axis about which the rake wheel rotates;
- a plurality of tines that extend outward from the center hub, the tines defining an outer circumference for engaging a surface over which the rake wheel rotates;
- a first set of fasteners for securing the plurality of tines in the center hub;
- a first disk having an outer surface and an inner surface, the outer and inner surfaces extending radially toward the outer circumference of the tines;
- a second disk having an outer surface and an inner surface, the outer and inner surfaces extending radially toward the outer circumference of the tines;
- and
- a second set of fasteners that extend between the first and second disks that clamp the tines between the inner surface of the first disk and the inner surface of the second disk, wherein the disks limit displacement of the tines in the axial direction relative to the rotational axis and permit the tines to move circumferentially between the disks.
