OPERATING FORCE-TRANSMITTING MECHANISM IN PADDY FIELD WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To protect a hydraulic pressure detecting operation system and a planting clutch operating system from external force and surely carry out the on-off of the planting clutch. ;SOLUTION: A planting part 10 is liftably supported through a lifting and lowering link mechanism 8 by a hydraulic cylinder apparatus. A hydraulic control valve for controlling the hydraulic cylinder apparatus is connected through a hydraulic pressure detecting operation system to a float 14 and the hydraulic pressure control valve is controlled by vertical transfer of the float 14. A hydraulic and planting lever is connected through a planting clutch operating system to a planting clutch and when the hydraulic and planting lever is operated to a prescribed position, the on-off operation of the planting clutch is carried out. Each operating system is protected from external force and deformation, etc., of each operating system is prevented by arranging the hydraulic pressure detecting operation system and the planting clutch operating system along each lower link 8b and a machine frame.;COPYRIGHT: (C)1999,JPO
