摘要： Mineral bits (10, 100) and associated mounts (30, 116, 200) for use during excavation and mining operations are disclosed. An exemplary bit (10) has a front region (12) and an opposite rear region (14) and comprises a head portion (16) and a mounting portion (18) secured to the head portion (16). The mounting portion (18) can be configured to be releasably retained by a mount (30). A rounded transition (22) disposed in the front region (12) of the bit between the head portion (16) and the mounting portion (18) provides a clearance (C) between the head portion (16) and the mount (16). Mineral bits (10, 100) disclosed can be inserted into and withdrawn from mounts (30, 116, 200) by linear and/or rotational movement.

摘要： A cutter bit adapted to be fixed onto a working surface of a rotating drum of a milling, planing, mining or reclaiming machine is provided. The body of the cutter bit is generally formed of a hardened steel, the cutting surface may be a diamond composition fixed in a step in the upper end of the cutter bit. The cutter bit includes a cutting surface, and the cutting surface may include non-parallel side edges and an upper cutting edge parallel to a lower edge. The lower edge may be any length sufficient to inhibit unintended angular displacement of the cutting surface during operation of the working surface. Alternatively or in addition, the cutting surface may be defined by three edges to allow the cutting surface to be removed and repositioned in at least a second orientation.

摘要： The subject matter of the invention is a bit holder for an earth working machine, in particular a road milling machine, having a support member onto which an insertion projection is indirectly or directly attached on an insertion projection side, the insertion projection comprising at least one convex abutment surface and one pressure surface. In a bit holder of this kind, working forces can be dissipated in stress-optimized fashion into an attached base part when provision is made that the insertion projection comprises two convex abutment surfaces that are arranged at a distance from one another.

摘要： The invention relates to a bit holder for an earth working machine, in particular a road milling machine, that comprises a bit receptacle in the region of a working side of a support member and that indirectly or directly carries an insertion projection on an insertion projection side of the support member, the support member comprising two stripping surfaces [first or second stripping surfaces] that form a stripping surface pair and are at an angle to one another. In order to achieve a stable and long-lived configuration with such a bit holder, provision is made according to the present invention that the support member comprises at least one further stripping surface that is at an angle to the two stripping surfaces of the stripping surface pair.

摘要： A cutter bit includes a wear resistant element replaceably mounted to a front surface immediately below the cutting surface of the cutter bit. The body of the cutter bit is generally formed of a hardened steel, the cutting surface can be a diamond composition fixed in a step in the upper end of the cutter bit including side edges that taper laterally outwardly toward a lower edge of the cutting surface situated adjacent to the wear resistant element and the wear resistant element is preferably formed of a carbide composition or a sintered diamond composition. The wear resistant element can have an upper edge that closely conforms to the shape of an adjacent lower edge of the cutting surface, and can be coupled to a front end of a stem passing through an opening in the cutter bit immediately below the cutting surface, the opening being perpendicular to at least a portion of the back surface of the cutter bit.

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.
