摘要： A cutting bit assembly includes a block, a bit sleeve, and a seal. The block includes a first bore and a fluid passage. The fluid passage includes a first portion and a second portion in fluid communication with the first portion. The first portion is oriented obliquely with respect to the first bore, and the second portion extends at least partially around the perimeter of the first bore. The bit sleeve includes a shank, a flange, and a second bore extending through the shank and the flange. The shank is positioned within the first bore of the block such that a surface of the flange engages a first end surface of the block. The seal is positioned between the second portion of the fluid passage and the shank to prevent contact between a fluid in the fluid passage and the outer surface of the shank.

摘要： A crawler track includes a link and is driven in a direction of travel by a sprocket having a plurality of teeth. The link includes a pad, a first grouser, and a second grouser. The pad defines a first surface, a second surface opposite the first surface, a first end, and a second end spaced apart from the first end along the direction of travel. The pad defines at least one opening extending through the pad between the first surface and the second surface, and the opening is operable to receive a sprocket tooth. The first grouser is positioned on the first surface proximate the first end of the pad, while the second grouser is positioned on the first surface proximate the second end of the pad. The first grouser and the second grouser extend in a direction substantially perpendicular to the direction of travel of the track.

摘要： A conveyor flight for a chain comprising at least two spaced apart links, and two side plates that connect the links, with each side plate including two spaced apart extension pins extending from the side plate. The flight comprises a metal support, and the metal support includes two spaced apart cylindrical portions adapted to receive the two spaced apart extension pins. The flight also includes a flexible casing surrounding the metal support.

摘要： A chain driven by two sprockets spaced a short distance apart along their common axial centerline. The chain includes elongated pins that extend beyond the outer surfaces of the chain link plates, on both sides, by a distance about equal to the width of the spaced apart sprockets. The chain is aligned midway between the sprockets, and the sprocket teeth drive on the extended portion of the chain pins. Where a flight is attached to the chain links, the pins are extended still further, to fit into the indentations or holes in the flights. This provides an exposed length of each pin in alignment with the sprocket on each side for driving purposes. The chain has a piece extending between the plates to reduce the likelihood of a pin extending further outside of one side plate or the other. A shoulder on the pin further reduces the likelihood of this happening.

摘要： A continuous miner includes a mining portion, a support frame connected to the mining portion, and a discharge portion pivotally attached to the support frame. The discharge portion swings laterally relative to the support frame about a pivot axis. The continuous miner also includes a conveyor extending across the support frame and discharge portion. The conveyor moves mined material from the mining portion to the discharge portion. The conveyor includes a conveyor chain, a rear roller, and a front roller. The continuous miner also includes a conveyor drive system for driving the conveyor chain. The conveyor drive system is located on a bottom surface of the continuous miner and between the rear roller and the front roller.

摘要： Methods, systems, and computer-readable medium storing instructions for turning a cutting drum of a mining machine at a maintenance speed. One method includes receiving, at a controller, input signals from an operator interface, the input signals including a signal to initiate turning of the cutting drum at the maintenance speed, and transmitting, in response to the input signals, control signals from the controller to a cutting drum turning mechanism included in the mining machine, the control signals instructing a switch included in the cutting drum turning mechanism to electrically couple a cutter motor and a variable frequency drive.
