Abstract
A disk reclaimer, having spring mounted harrow and carrier teeth, is described. The spring loaded teeth are less subject to binding or breakage when reclaiming highly cohesive bulk materials such as phosphate shales.
Claims4
In a disk reclaimer, a tooth and mounting rack for improved reclaiming of cohesive bulk materials comprising:
- a. harrow and carrier teeth of flat spring steel formed into a "J" shape,
- b. a horizontal tubular support member having upper and lower open slots along its length, said slots adopted for insertion of a short limb of the "J" shaped harrow and carrier teeth wherein a long limb of the teeth is disposed downwardly from the tubular support member parallel to the short limb and substantially perpendicular to the plane of the reclaimer disk, a flat side of the spring "J" teeth facing in the direction of rotation of the reclaimer disk,
- c. means for removably attaching the "J" teeth to tubular support member, it being provided that the spring rate of the "J" teeth is high enough to permit normal reclaiming action but sufficiently resilient whereby on encountering zones of high resistance in the cohesive bulk material the "J" teeth deflect opposite in direction to the imposed force and returns to their original position after traversing the zone of high resistance.
