<P>PROBLEM TO BE SOLVED: To provide a rotation apparatus for an extended leveling plate of an agricultural working machine that has no risk of damage even if an interlocking arm is brought into contact with obstacles, etc., when the agricultural working machine is moved in a state in which the extended leveling plate is developed. <P>SOLUTION: The rotation apparatus 40 for an extended leveling plate includes: a motor 43 for forward and reverse rotations that is arranged at the upper side of the plowing rotor of a soil puddling working machine 1; a power transmission mechanism part 47 that is connected to the revolving shaft of the motor and transmits the rotating power of the motor; the interlocking arm 53 that is connected to the output shaft of the power transmission mechanism part and is rotated together with the output shaft; and a connected body 60 that is connected to between the interlocking arm 53 and an extended leveling plate (left) 30L and rotates the extended leveling plate (left) 30L following the rotation of the interlocking arm 53. The interlocking arm 53 has an arm body part 56 and an arm support part 55 that is fixed on the base of the arm body part, is connected to the output shaft of the power transmission mechanism part 47 and is rotated together with the output shaft. The arm body part 56 has its base side rotatably connected to the arm support part 55 and is fixed on the arm support part 55 through a shear pin 57. <P>COPYRIGHT: (C)2013,JPO&INPIT |
