The cutter bit may also include a plurality of circumferentially-spaced ribs projecting radially outwardly from an outer peripheral surface of at least one of the leading end, conical-shaped tip portion, the rearward, frustoconical-shaped tip portion, or the frustoconical-shaped body portion.

This disclosure relates to a disk cutter (100) for a cutting assembly of a rock excavation machine. The disk cutter comprising a cutter body (102) including at least one light-weighting aperture (110).

A system for monitoring wear on ground engaging tools of an agricultural implement includes a ground engaging tool supported relative to a frame of the agricultural implement, the ground engaging tool configured to rotate with engagement of the ground during operation of the agricultural implement, a non-contact sensor configured to detect a parameter indicative of wear on the ground engaging tool, and a controller communicatively coupled to the non-contact sensor. The controller is configured to determine a status of the wear on the ground engaging tool based on sensor data received from the non-contact sensor.

A cutter bit for a work tool on a machine includes a leading end, conical-shaped tip portion, a rearward, frustoconical-shaped tip portion extending axially rearwardly from the leading end, conical-shaped tip portion, an annular ledge extending radially outwardly from a trailing edge of the rearward, frustoconical-shaped tip portion, a frustoconical-shaped body portion extending axially rearwardly from an outer circumferential edge of the annular ledge, a cylindrical collar portion extending axially rearwardly from a trailing edge of the frustoconical-shaped body portion, and a trailing end, cylindrical-shaped shank portion extending axially rearwardly from the cylindrical collar portion. The cutter bit may also include a plurality of circumferentially-spaced ribs projecting radially outwardly from an outer peripheral surface of at least one of the leading end, conical-shaped tip portion, the rearward, frustoconical-shaped tip portion, or the frustoconical-shaped body portion.

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.

A cutting device for engaging a rock face includes a disc body supported for rotation about an axis of rotation, and a plurality of peripheral portions removably secured to the disc body. Each of the peripheral portions including a plurality of cutting bits positioned on a peripheral edge. The peripheral edge of each peripheral portion is aligned with the peripheral edges of adjacent peripheral portions.

The present disclosure relates generally to systems and methods for sensing wear in machines designed to reduce or break-down material. More particularly, the present disclosure relates to systems and methods for sensing wear of reducing elements used by excavation machines such as surface excavation machines. The present disclosure relates to a wear sensing system including a multi-level wear sensor protection system. The multi-level wear sensor protection system includes a first level of protection, a second level of protection, and a third level of protection.

A tooth for a cutter head includes a tooth body portion for connecting to an adapter; and a pick point portion comprising an end portion with a substantially planar surface, sides extending in an outward direction from the end portion to the tooth body, and a front and/or back with curvature which expands in thickness from the end portion to the tooth body portion. The tooth body portion and the pick point portion have a rounded cross-section comprising a central beam with a bottom base extending perpendicular from the beam at a lower end of the beam and a top shoulder on an upper end of the beam.

A tool holder insertion device includes a frame extending from a proximal end to a distal end, the frame including first and second longitudinal arms extending between the distal end and the proximal end. The frame also includes a distal transverse arm connected to respective distal ends of the first and second longitudinal arms, a proximal transverse arm opposite the distal transverse arm, and an internal space extending from the distal transverse arm, the internal space forming an insertion opening. The tool holder insertion device also includes a drive assembly fixed to the frame, the drive assembly including a pushing surface that is movable within the internal space toward the distal end of the frame.
