ABSTRACT:
A hopper and hood combination for muck transfer in a tunneling machine, and a tunneling machine having the same, in which a muck collar is mounted to a cutterhead support and projects into a rotatable cutterhead. A muck chute on the muck collar feeds earth to an earth conveyer when the muck collar and muck chute are in a hopper orientation. The muck chute and muck collar are rotatable relative to the earth conveyor to a hood orientation in which the muck chute restricts earth flow to the earth conveyor. Rotation of the hopper/hood from one orientation to the other is by brief interconnection thereof to the cutterhead without any necessity for any disassembly or reconstruction of the tunneling machine.
