【発明の属する技術分野】
本発明は育苗箱がコンベア上で順次移動する間に、土入れ及び播種及び覆土などの播種作業を自動的に行う播種施設に関する。
【０００２】
【発明が解決しようとする課題】
従来、育苗箱を搬送する播種コンベヤに播種機を取付け、育苗箱に連続的に播種する技術があるが、育苗箱の床土上面に播種する催芽籾を播種機の播種ホッパーに作業者が運んで投入していたから、労力の軽減及び省力化などを容易に行い得ず、播種コストの低減などを容易に図り得ない等の問題がある。
【０００３】
【課題を解決するための手段】
請求項１に係る発明によれば、複数の育苗箱に連続的に播種するための播種機を設置した播種コンベヤと、種籾貯蔵部の催芽籾を前記播種機に空気搬送させるための搬送ホースとを備えてなる播種施設において、複数列の前記播種コンベヤにそれぞれ配置する前記播種機には、切換部材を介して前記搬送ホースの出口側を連結させ、前記各播種機の籾量を満量センサにて検出して、前記切換部材を作動させるように構成したものであるから、前記各播種機に対して前記搬送ホースなどを兼用して、催芽籾の搬送構造の簡略化及び低コスト化を容易にでき、前記各播種機の籾量を作業者が確認する手間を省き、適量の催芽籾を前記播種機に自動的に供給できるものである。
【０００４】
【０００５】
請求項２に係る発明によれば、前記搬送ホースの入口側には、詰センサと振動部材とを設け、前記搬送ホースの入口側の籾詰りを前記詰センサにて検出して、前記振動部材を作動させるものであるから、催芽籾が前記搬送ホースの入口側で詰る不具合をなくし、略一定量の催芽籾を搬送ホースに連続的に供給でき、催芽籾の搬送効率を向上でき、前記搬送ホースの途中での籾詰りを防止できるものである。
【０００６】
請求項３に係る発明によれば、前記各播種機には、前記切換部材を介して前記搬送ホースの出口側を連結させると共に、前記切換部材を作動させるための選択部材を備えたものであるから、特定の播種コンベヤだけを用いて播種作業を行う場合、該播種コンベヤの播種機にだけ催芽籾を供給でき、催芽籾の消費量を低減でき、催芽籾の損傷を防止できるものである。
【０００７】
請求項４に係る発明によれば、前記切換部材にて分岐された搬送方向下流側の各搬送ホースの出口には、前記各播種機に対応させるサイクロンをそれぞれ設け、前記各サイクロンでは催芽籾を搬送空気から分離して、その分離した催芽籾を前記播種機に送出させるように構成したものであるから、前記搬送ホースの出口と前記播種機との間の連結部から、催芽籾が外部に漏出するのを防止でき、前記搬送ホースの出口では、催芽籾が空気搬送力にて損傷するのを防止でき、前記搬送ホースの出口と前記播種機の連結部の構造を簡略化でき、前記連結部での籾詰りを防止できるものである。
