Patent ID: 8104400

Claim:
A husking-roll driving device in a hull remover, provided with a pair of husking-rolls which are driven and rotated by first and second motors, a first drive system, a second drive system, a first belt clutch mechanism, and a second belt clutch mechanism, wherein the pair of husking-rolls rotated in the internal direction, and at different rotation numbers from each other, the first drive system includes: a first large-diameter pulley fixed to one rotation axis of a pair of husking-rolls; a first small-diameter pulley fixed to the other rotation axis; and a first no-end belt which is wound among the first large-diameter pulley, the first small-diameter pulley, and the drive pulley of the first motor, to connects the pulleys, the second drive system includes components of: a second small-diameter pulley which is fixed to the one rotation axis fixing the first large-diameter pulley, a second large-diameter pulley fixed to the other rotation axis fixing the first small-diameter pulley, and a second no-end belt which is wound among the second small-diameter pulley, the second large-diameter pulley, and the drive pulley of the second motor and connects the components, a first belt clutch mechanism inputting power transmission to the first large-diameter pulley, is further provided in the first drive system, a second belt clutch mechanism inputting power transmission to the second large-diameter pulley, is further provided in the second drive system, the first belt clutch mechanism includes a first arm member which is extended in the radius direction around one rotation axis, and which is rotated in such a way that a first rotation track is drawn over the outer periphery of the first large-diameter pulley, a first tension clutch pulley installed at a point portion of the first arm member, and a first actuator rotating a first arm member, the first actuator can switch a position at which the first no-end belt in the first drive system is wound on the first large-diameter pulley for power transmission and a position at which winding is avoided, the second belt clutch mechanism includes a second arm member which is extended in the radius direction around the other rotation axis, and is rotated in such a way that a second rotation track is drawn over the outer periphery of the second large-diameter pulley, a second tension clutch pulley installed at the point portion of the second arm member, and a second actuator rotating a second arm member, and the second actuator can switch between a position at which a second no-end belt in the second drive system is wound on the second large-diameter pulley for power transmission and a position at which winding is avoided.
