Zusammenfassung:PROBLEM TO BE SOLVED: To provide a spraying amount regulating system for a fertilizer spreader in which a spraying amount can be properly regulated on the basis of the PTO rotational speed.SOLUTION: A spraying amount regulating system for a fertilizer spreader is provided for regulating a spraying amount of a spray material by controlling an actuator 130 provided in a fertilizer spreader 100 installed in a tractor 1. The spraying amount regulating system has a hopper 110 for storing the spray material, a shutter 152 for regulating an opening degree to discharge the spray material from the hopper 110 in conjunction with an actuator 130, a spreader mechanism for spraying the spray material using a PTO rotation of the tractor 1, and a calculation unit 22. The calculation unit 22 calculates a spraying width from the PTO rotational speed of the tractor 1 and calculates an opening degree of the shutter 152 using the calculated spraying width.SELECTED DRAWING: Figure 1 【課題】PTO回転数をふまえて散布量の調整を適切に行うことができる肥料散布機用散布量調整システムを提供することを目的とする。【解決手段】トラクタ1に装着する肥料散布機100に備えるアクチュエータ130を制御して散布物の散布量を調整する肥料散布機用散布量調整システムにおいて、散布物を収納するホッパー110と、アクチュエータ130と連動してホッパー110から散布物を排出するための開度を調整するシャッター152と、トラクタ1のPTO回転を用いて散布物を散布する散布機構と、演算部22とを有し、演算部22は、トラクタ1のPTO回転数から散布幅を計算して、計算した散布幅を用いてシャッター152の開度を算出する。【選択図】図1
