摘要： A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.

摘要： A method of making a strike construction for a pick tool, a strike construction for a pick tool and a pick tool. The strike construction comprises a strike tip (2) and a support body (20), in which respective attachment ends (10,22) of each of the strike tip and support body are joined to each other, the attachment end of the strike tip is coterminous with cemented carbide material comprised in the strike tip, and the attachment end of the support body is coterminous with cemented carbide material comprised in an end portion of the support body, the end portion being configured such that sides of the support body depend divergently from its attachment end. The method includes providing the strike tip (2) and a precursor body (28) for the support body, in which a proximate end (25) of the precursor body is coterminous with cemented carbide material comprised in an end portion of the precursor body, the end portion of the precursor body being configured such that sides of the precursor body depend divergently from its proximate end, the area of which is less than the area of the attachment end of the support body (20). The method further including processing the end portion of the precursor body to increase the area of the proximate end to that of the attachment end of the support body; and joining the respective attachment ends of the strike tip and the support body to provide the strike construction.

摘要： A pick assembly is provided, comprising a bit assembly and a holder assembly; the bit assembly comprising a bit support body, a fastener mechanism and a deflectable member, cooperatively configured such the deflectable member can be deflected responsive to the progressive coupling of the bit support body to the fastener mechanism. The holder assembly comprises a holder body and is configured for accommodating and retaining the bit assembly by interference means. The holder assembly and bit assembly are cooperatively configured such that the retention of the bit assembly by the holder assembly by interference means can be progressively increased responsive to the progressive coupling of the bit support body with the fastener mechanism when the bit assembly is accommodated by the holder assembly, operative to prevent substantial movement of the bit support body relative to the holder body in use.
