SEEDLING TRANSPLANTER ELEVATING/LOWERING MECHANISM FOR RIDING TYPE RICE TRANSPLANTER

摘要

PROBLEM TO BE SOLVED: To surely keep a seedling transplanting device to a prescribed height position such as a carrying height position, a transplanting height position. ;SOLUTION: Behind a self-traveling machine body 1, the rear tips of upper and lower links 13 and 15 freely rotatably connected to the periphery of respective first and third right/left facing axial cores P1 and P3 are freely rotatably connected to the periphery of second and fourth right/left facing axial cores P2 and P4 at a vertical link for fixing the seedling transplanting device to constitute a quadruple link mechanism 11. Then, the mechanism 11 is provided with a wire body for regulating lowering 30 which bends for permitting the shortening operation of a hydraulic cylinder 12, which is connected to a pull-up member 24 pivotaly connected to a spindle constituting the axial core P4, raises the mechanism 11 by shortening operation and lowers the mechanism 11 by prolonging operation, and stretches for regulating the prolonging operation length of the cylinder 12 to be a set length.;COPYRIGHT: (C)1998,JPO
