<p><P>PROBLEM TO BE SOLVED: To provide a rotation apparatus for an extended leveling plate that surely brings down an extended leveling plate to a working position side or a storage position side when an interlocking arm is rotated in a state in which a first leveling plate is raised. <P>SOLUTION: The rotation apparatus 40 for an extended leveling plate that is mounted on a soil puddling working machine 1 equipped with a shield cover for covering the upper part of a rotatably supported plowing rotor 23, a second leveling plate (left) 29L which is arranged rotatably in the vertical direction behind the shield cover and levels cultivated soil plowed by the plowing rotor 23 and an extended leveling plate (left) 30L rotatably supported around a shaft part 31 extended in the cross direction at an end part in the right and left directions relative to the progress direction of the second leveling plate (left). The apparatus includes: a motor for forward and reverse rotation arranged at the upper part of the shield cover; the interlocking arm 53 which is extended in an approximately vertical direction, connected to a spindle 51 receiving power from the motor and rotated, and is turned; and a connected body 60 for connecting the tip end part of the interlocking arm to the extended leveling plate (left) 30L. The base end part of the interlocking arm 53 is connected to the spindle 51 in a state in which the rotary central shaft line of the base end part is inclined to the front side in the progress direction. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
