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.

摘要: In one aspect of the invention, an aggregate removal system includes a self propelled vehicle with a frame and a conveyor. The conveyor has an intake end and an output end. A milling drum is connected to an underside of the frame and is enclosed within a milling chamber, which is defined by a front plate, side plates, and a moldboard. The drum is configured to drop aggregate within the milling chamber onto the intake end of the conveyor that protrudes into the milling chamber. The conveyor is configured to remove the aggregate from the milling chamber, and the conveyor also has at least one dust suppressant nozzle configured to apply a dust suppressant to aggregate carried by the conveyor.

摘要: A degradation assembly comprises a rotating portion and a fixed portion. The rotating portion comprises a wear resistant tip bonded to a carbide bolster. The bolster is attached to a shaft adapted for a rotatable connection within a bore of the fixed portion. The fixed portion is adapted for a rigid connection to a driving mechanism. The fixed portion includes an O-ring slot formed within its bore and with an O-ring being disposed therein. The O-ring is at least 15 percent compressed such that the O-ring resists rotation of the shaft.
