    摘要: In one aspect of the present invention, a pick assembly is configured that comprises a pick shank configured to be press fit directly within a bore of a block. The pick shank comprises an inside and outside surface. The pick comprises a pick head opposite the shank. The shank comprises at least one longitudinal recess extending towards the pick head along the shank from a distal end of the shank. The recess allows the shank to resiliently collapse upon insertion into the bore while maintaining a press fit between the bore and the shank.

    摘要: A degradation assembly, comprising a platform comprising a surface. A plurality of picks each comprising a hard tip and a shank may be mounted on the surface. A plurality of sensors may also be disposed within the platform such that they can measure impacts on at least one of the picks. The sensors may be in communication with a processor. The degradation assembly may be capable of detecting and determining the location of a selected pick measuring impacts on at least one pick with at least one sensor, detecting a variation on the at least one pick with the at least one sensor, and determining a location of the at least one pick with more than one of the sensors.

    摘要: In one aspect of the invention, a degradation pick comprises a bolster disposed intermediate a shank and an impact tip. The shank comprises an outer diameter and first and second ends. The shank is coupled to the bolster through the first end and the second end is adapted for insertion into a central bore of a holder attached to a driving mechanism. The shank comprises a hollow portion disposed within the outer diameter and between the first and second ends. The hollow portion may comprise an opening that is disposed in the second end. In some embodiments the hollow portion may comprise a length that is at least as great as the outer diameter.

    摘要: In one aspect of the invention, a pick assembly comprises a pick shank press fitted within a bore of a pick holder. The pick comprises a pick head opposite the shank. The shank also comprises at least one longitudinal slot extending towards the pick head along the shank from a distal end of the shank. The slot allows the shank to resiliently collapse upon insertion into the bore while still allowing the shank to maintain a press fit while within the bore.
