Description
そして、前記制御装置14のマイクロコンピュータは、前記演算結果に基づき目標散布量が実現されるように、例えば、前記調量弁14bの調量値を連続的に自動制御する。その結果、前記余水管路15を介して前記ポンプ2から前記タンク4へと戻される余水の量が変化するので、前記液体分配筐7へと送られる散布液Lの流量、すなわち、前記各稼働ノズルnからの実散布量も、自動的に調節される。よって、前記散布幅Wと移動速度Vのいずれが変化しても、単位面積当たりの目標散布量q通りの散布が可能となる。前記吐出管路6における散布液流量は、前記制御装置14へと連続的に出力されているので、計算通りの均一量散布が行われているか否かが、常に前記制御装置14でチェックされ、信頼性が向上する。

Claims (1)
- 散布幅(W)と移動速度(V)のいずれが変化しても単位面積当たりの目標散布量(q)通りの散布が可能とされている液体散布装置(1)であって、実際に散布される散布液(L)の流量を検知する第一のセンサとしての散布流量センサ(11)と、同一の散布ノズルを有する伸縮式ブームの伸縮操作により変化する散布幅を知るために必要な要素を検知する第二のセンサとしての前記散布流量センサ(11)の下流側に設けた散布圧力センサ(12c)と、液体散布装置移動速度センサ(13)と、これらのセンサ(11,12c,13)の検知結果に基づく前記散布幅(W)と移動速度(V)と目標散布量(q)との乗算により該目標散布量(q)を実現するに必要な単位時間当たりの液体流量(Q)を演算するとともに該液体流量(Q)が実現されるように制御する制御装置(14,14a,14b)と、を備えている、液体散布装置。
