Abstract
In such fields as road milling, mining and trenching it is often desirable to engage and degrade tough materials such as asphalt, concrete and rock. To do so, degradation picks comprising hardened tips may be secured to an exterior of a rotatable drum so as to be repeatedly brought into contact with a surface of a material to be degraded. To secure such degradation picks to the rotatable drum, a toroidal body comprising an interior surface rigidly attachable to the rotatable body and an exterior surface comprising a plurality of bore holes disposed there around may receive a plurality of degradation picks secured within the bore holes.
Claims17
A degradation pick support, comprising:
- a toroidal body comprising an interior surface and an exterior surface;
- a rotatable body comprising a generally helical flange disposed around an exterior surface of the rotatable body, wherein:
- the helical flange is a same height off the exterior surface of the rotatable body as the toroidal body is off the exterior surface of the rotatable body, measured in a direction normal to the exterior surface of the rotatable body;
- and
- the rotatable body is rigidly secured to the toroidal body, with the interior surface of the toroidal body being rigidly secured to the rotatable body;
- and
- a plurality of bore holes disposed around the exterior surface of the toroidal body.
