機における植付部自動上昇装置。[Scope of Claim for Utility Model Registration] A planting section that can be raised and lowered by hydraulic operation is supported at the rear of a traveling aircraft that changes direction by pressing left and right steering pedals, and a transmission section to the planting section is supported. In a riding rice transplanter, in which a planter lever for intermittent operation and a hydraulic lever for controlling hydraulic pressure are connected in a detachable manner so that power is transmitted to the planting section when the planting section is raised or lowered, A movable rod that can be freely rotated and engaged with the hydraulic lever and disengaged from the hydraulic lever is provided near the base of the hydraulic lever and the planter lever, and the floating rod is arranged to always return to a fixed posture corresponding to the lowering setting position of the hydraulic lever. In the vicinity of the floating rod,
An operating rod is provided that can be engaged with and separated from the floating rod and can be swung in one direction, and the operating rod is interlocked and connected to a steering pedal, and as the steering pedal is depressed, either the operating rod or the floating rod is pressed. and move the hydraulic lever to the raised position of the planting section and the blunter lever to the off position/At this time, the floating rod is disengaged from the operating rod and the hydraulic lever, and corresponds to the lowered setting position of the hydraulic lever. In addition to being configured to return to the original position, the hydraulic lever is provided with an automatic neutral return mechanism that automatically returns the hydraulic lever from the raised position to the neutral position when the planting part reaches its lifting limit. An automatic planting section lifting device in a riding rice transplanter characterized by:
