Universal Pick Adapter

Abstract

An adapter may allow for non-rotating degradation tips to be secured to holders traditionally used for accepting rotatable bits. Such an adapter may comprise a body comprising an interface on one surface and a seat on an opposing surface. The interface may comprise a form complementary to an end of a holder and the seat may comprise a form for accepting a hardened tip.

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This patent application claims priority to U.S. Provisional Pat. App. No. 62 / 026,345 entitled “Universal Pick Adapter” and filed Jul. 18, 2014, which is incorporated herein by reference for all that it contains.BACKGROUND OF THE INVENTION

[0002] Degradation picks are known to be used in such fields as road milling, mining and trenching to engage and degrade tough materials such as asphalt, concrete and rock. Such degradation picks may be secured to an exterior of a rotating drum or continuous chain so as to be repeatedly brought into contact with a surface of a material to be degraded. Each degradation pick may comprise a hardened tip designed for repeated impact with a tough material. Such repeated impact may break up the tough material into aggregate pieces that may be removed. To secure such degradation picks to a rotating drum or continuous chain, a generally cylindrical shank opposite the hardened tip may be disposed within a bore with...

DETAILED DESCRIPTION OF THE DRAWINGS

[0015]FIG. 1 shows an embodiment of a road milling machine 100 of the type commonly used to engage and degrade asphalt or concrete to construct or resurface roads and other large surfaces. The road milling machine 100 may be supported and transported by continuous tracks 150, wheels or other means known in the art. A rotatable drum 110 may be secured to an underside of the road milling machine 100 with a plurality of degradation picks attached to an exterior thereof. As the rotatable drum 110 is rotated, the degradation picks may repeatedly engage a surface upon which the road milling machine 100 is traveling.

[0016]FIG. 2 shows an embodiment of a mining machine 200 of the type commonly used to engage and degrade rock and other subterranean formations to extract valuable materials from the earth. The mining machine 200 may comprise a continuous chain 210 with a plurality of degradation picks 220 (shown in magnified view) secured thereto. Each of th...
