ところが、上記施肥装置では、施肥作業にペースト状の肥料を使用した場合に 、ペースト状肥料が肥料タンク、各パイプ、施肥ポンプ、及び肥料タンク、及び 施肥ノズル中に固着し、次に使用する際に、肥料が各構成部内を流通しなくなっ て、施肥作業が行なえなくなるという問題があった。 However, in the above fertilizer application, when paste-like fertilizer is used for fertilization work, the paste-like fertilizer adheres to the fertilizer tank, each pipe, the fertilizer pump, the fertilizer tank, and the fertilizer nozzle, and is used next time. Moreover, there was a problem that fertilizer could not be fertilized because the fertilizer could not be distributed in each component.
【０００４】 そのために、施肥作業終了後は、各構成部内を水洗いするようにしているが、 ペースト状の肥料を完全に抜きとるのに手間を要していた。Therefore, after the fertilization work is finished, the inside of each component is washed with water, but it takes time to completely remove the paste-like fertilizer.
【０００５】[0005]
そこで、本考案では、植付爪を駆動する植付ケースに施肥ポンプを連動連結し 、同施肥ポンプの吸入口に肥料タンクを肥料吸入パイプを介して連通連結すると 共に、同施肥ポンプの吐出口に施肥ノズルを肥料吐出パイプを介して連通連結し た施肥装置において、肥料タンクと肥料吸入パイプの中途部とを洗浄水供給パイ プを介して連通連結し、同洗浄水供給パイプの中途部に水源連結パイプを流路切 換バルブを介して連通連結して、同流路切換バルブの切換操作により肥料タンク 側又は施肥ポンプ側の少なくとも一方に洗浄水供給パイプ中を通して洗浄水を供 給可能としたことを特徴とする施肥装置を提供せんとするものである。 Therefore, in the present invention, the fertilizer pump is interlockingly connected to the planting case that drives the planting claw, and the fertilizer tank is connected to the inlet port of the fertilizer pump through the fertilizer inlet pipe, and the outlet port of the fertilizer pump is also connected. In the fertilizer application, in which the fertilizer nozzles are connected to each other via the fertilizer discharge pipe, the fertilizer tank and the middle part of the fertilizer suction pipe are connected to each other via the wash water supply pipe to connect to the middle part of the wash water supply pipe. By connecting the water source connection pipes through the flow path switching valve, the cleaning water can be supplied to at least one of the fertilizer tank side and the fertilizer pump side through the cleaning water supply pipe by the switching operation of the flow path switching valve. It is intended to provide a fertilizer application characterized by the above.
