Abstract
An improved paddle design for use on the beater mechanism of a manure spreader enables the spreader to satisfactoriloy handle a broader range of manure consistencies and to distribute the same over a more uniform and wide spread pattern. The paddle has a dished or cupped shape, is substantially symmetrical about its centerline, and includes a curved main body portion and integrally formed upper engaging and lower mounting portions. The upper portion has a curved shape similar to the main body portion and is inclined inwardly toward the axis of curvature of the main body portion, thus providing a concave working surface. The lower portion presents a planar surface for mounting the paddle on a beater shaft. The paddle, being symmetrical, can be used on either the left or right sides of a spreader.
Claims9
A material engaging and distributing paddle, comprising an inwardly curved main body portion and an inwardly curved upper peripheral edge portion integrally formed with the main body portion and curved inwardly along the same axis of curvature as said main body portion, said upper edge portion further being inclined toward said axis of curvature of said main body portion, said paddle having a centerline about which said main body and upper edge portions are substantially symmetrical.
A material engaging and distributing paddle comprising a curved main body portion having a first predetermined radius of curvature, a curved upper edge portion having a second predetermined radius of curvature and integrally formed with the main body portion, and a lower planar generally rectangular shaped mounting portion integrally formed with the main body portion for detachably mounting said paddle on a mounting shaft, said upper edge portion being inclined inwardly toward the axis of curvature of said main body portion.
A symmetrically shaped material engaging and distributing paddle comprising a curved main body portion and an upper peripheral edge portion integrally formed with the main body portion and curved inwardly along the axis of curvature of said main body portion, said upper peripheral edge portion and said main body portion forming an arcuate shaped crease at their integral connection, said upper edge portion being inclined inwardly along said crease.
