摘要： A mining machine includes a boom, a cutter head, a valve, and an actuator. The boom defines an internal chamber and includes a first end coupled to a frame, a second end, and an opening in fluid communication with the internal chamber. The cutter head includes a plurality of cutting bits and is supported on the second end of the boom. The valve is coupled to the boom and is movable between a closed position in which the opening is covered and an open position in which the opening is at least partially uncovered. The actuator is coupled to the valve to selectively move the valve between the closed position and the opened position.

摘要： Systems and methods for operating a mining machine. One system includes a controller, a stationary object, and a radar device. The radar device transmits radio waves toward the stationary object and detects reflections of the radio waves. The controller obtains timing information regarding the radio waves and the reflections. Based on the timing information, the controller is configured to determine a first distance between the radar device and the stationary object before sumping the mining machine into material and a second distance between the radar device and the stationary object after sumping the mining machine into the material. The controller is also configured to determine a sump depth of the mining machine based on the first distance and the second distance, compare the determined sump depth to a predetermined sump depth, and perform at least one automatic action when the determined sump depth does not satisfy the predetermined sump depth.

摘要： A cutter head for a longwall shearer includes a drum, a vane, and a plurality of cutting bits. The drum includes a first end and a second end and defines an axis of rotation extending therebetween. The vane is connected to the drum and extends in a helical manner along at least a portion of the axis. The vane defines an edge surface extending along an outer perimeter of the vane. The cutting bits are secured to the vane edge surface. Each cutting bit includes a block and a bit coupled to the block. The block is secured to the edge surface and extends beyond the outer perimeter of the vane.

摘要： A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.
