PROBLEM TO BE SOLVED: To provide a fertilizer applicator of a riding rice transplanter comprising an inexpensive and simple metering mechanism which is integrally mounted in the fertilizer applicator, and readily mounting and demounting the fertilizer applicator having the metering mechanism mounted in a traveling part of the riding rice transplanter.SOLUTION: The riding rice transplanter includes the fertilizer applicator 40 disposed at the rear of a machine body. The fertilizer applicator 40 is provided with: a fertilizer hopper 42 for housing a fertilizer a delivering part 43 disposed under the fertilizer hopper 42, and for delivering the fertilizer by a prescribed amount a fertilizing and transporting part for guiding the fertilizer delivered from the delivering part 43 to the vicinity of a fertilizing part and an air blasting part 45 for sending a carrier wind to the fertilizing and transporting part. In the riding rice transplanter, power is transmitted from a PTO (power take-off) output shaft of a traveling transmission case of the riding rice transplanter through a power transmission mechanism to the delivering part, and a friction disk type transmission is installed in the course of the transmission route of the power transmission mechanism. Furthermore, the friction disk type transmission is erected from the rear of the machine body of the riding rice transplanter and mounted in a fertilizer applicator frame for supporting the fertilizer applicator 40.COPYRIGHT: (C)2010,JPO&INPIT【課題】調量機構は安価で簡単な構成として、施肥機に一体的に取り付けられる構成とし、乗用田植機の走行部に対して調量機構を取り付けた施肥機を容易に着脱できる、乗用田植機の施肥機を提供する。【解決手段】肥料を収容する肥料ホッパー42と、該肥料ホッパー42の下部に配設され、肥料を所定量ずつ繰出す繰出し部43と、該繰出し部43より繰出される肥料を施肥部近傍まで案内する施肥搬送部と、該施肥搬送部に搬送風を送る送風部45と、を備えた施肥機40を機体後部に配設する乗用田植機において、前記乗用田植機の走行ミッションケースのPTO出力軸より動力伝達機構を介して繰出し部に動力を伝達し、該動力伝達機構の伝達経路途中に摩擦円板式変速装置を設け、該摩擦円板式変速装置を、乗用田植機の機体後部より立設して施肥機40を支持する施肥機フレームに取り付けた。【選択図】図3
