Title:
樹木粉砕機
Document Type and Number:
Japanese Patent JP6905660
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tree crusher which controls the feed of a crushing object by a feed roller to reduce the crushing overload of a crushing rotor in a mechanically simple structure without computer control.SOLUTION: A tree crusher has: a crushing rotor that rotates in accordance with torque from the prime rotor shaft; a feed roller that transports a crushing object to the crushing rotor side at the time of normal rotation; an intermediate shaft that rotates by interlocking with a feed roller; a centrifugal clutch that, when the rotor shaft of the crushing rotor has a regulated revolution speed or more, keeps a connected state for transmitting torque from the rotor shaft of the crushing rotor to the intermediate shaft and, when the rotor shaft of the crushing rotor has a revolution speed less than regulated, keeps the connection between the rotor shaft and the intermediate shaft in a cut-off state; and a spring type energization part that, when the centrifugal clutch is in a connected state, accumulates, as spring energization force, the energy of a part of torque transmitted from the rotor shaft of the crushing rotor to the intermediate shaft and, when the centrifugal clutch is in a cut-off state, reversely rotates the intermediate shaft and the feed roller by means of the accumulated spring energization force.SELECTED DRAWING: Figure 3
