It can be.

前記施肥装置７においては、各繰出ケース３７の下側の施肥パイプ４１に繰出された肥料は、ブロワ６１から送風パイプ５４を経て送られる圧風を受けて各施用ホース１８へ噴送されて、苗植装置１７の各フロート２３、２４で均平される苗植付土壌面へ施用される。又、施肥作用後に繰出室４５やホッパ２等に残留した肥料を機外へ取出回収するときは、排出弁４６を開いて、更には繰出ケース３７をホッパ２と共に傾斜回動軸５１の周りに後側へ回動させて傾斜させる。このときブロワ６１からの送風は切替弁６２で回収パイプ４７側へ切替えられて、この回収パイプ４７内を肥料が風圧搬送されて機外へ回収される。このようなホッパ２の傾斜回動に連動して、ブロア６１の回転数を高くするように構成して、残留肥料の回収作用を速かに行わせることができる。このブロワ６１の連動には、ブロア６１を駆動するエンジンの回転数や、伝動機構の切替え等を行う形態とする。又、前記送風パイプ５４にあっては、これに配設される特定の詰り個所の施用パイプ４１の分岐部における風速を高めることができるように、この施用パイプ４１への送風案内を行う堰板を送風パイプ５４内数個所に設けることができる。又、この堰板は送風パイプ５４内へ差込調節可能に設けたり、送風パイプ５４内に沿って移動調節可能にして詰り個所の風圧を高めるように設けることができる。更には、各施用パイプ４１への分岐部を開閉調節するシャッタ等との関連調節によって、各施用パイプ４１への粉粒体肥料の均等分配施用を行う形態とすることができる。 In the fertilizer 7, the fertilizer fed to the lower fertilization pipe 41 of each feeding case 37 receives the compressed air sent from the blower 61 through the blower pipe 54 and is jetted to each application hose 18. It is applied to the seedling planting soil surface that is leveled by the floats 23 and 24 of the seedling planting device 17. Further, when the fertilizer remaining in the feeding chamber 45, the hopper 2 or the like after the fertilization operation is taken out and collected outside the machine, the discharge valve 46 is opened, and the feeding case 37 is moved together with the hopper 2 around the inclined rotation shaft 51. Rotate to the rear and tilt. At this time, the air blown from the blower 61 is switched to the recovery pipe 47 side by the switching valve 62, and the fertilizer is conveyed by wind pressure through the recovery pipe 47 and recovered outside the apparatus. In conjunction with such tilt rotation of the hopper 2, it is possible to increase the rotational speed of the blower 61 so that the residual fertilizer can be collected quickly. In conjunction with the blower 61, the engine speed for driving the blower 61, the transmission mechanism, and the like are switched. Further, in the blowing pipe 54, a weir plate for guiding the blowing to the application pipe 41 so as to increase the wind speed at the branching portion of the application pipe 41 at a specific clogging portion disposed therein. Can be provided at several locations in the blower pipe 54. Further, the barrier plate can be provided so as to be adjustable in insertion into the blower pipe 54, or can be provided so as to be adjustable in movement along the blower pipe 54 so as to increase the wind pressure at the clogging portion. Furthermore, it can be set as the form which distributes and distributes the granular material fertilizer to each application pipe 41 equally by related adjustment with the shutter etc. which adjust opening and closing of the branch part to each application pipe 41.

前記ステアリングハンドル１０には、図９〜図１１のように中央部に操作部７０を設け、又、ダッシュボード９上の計器盤７１前縁には表示部７２を設けて、肥料の比重や、繰出量の設定可能に構成する。又、これら操作部７０と計器盤７１との間は、手動操作可能の施肥切替レバー７３を設ける。該操作部７０には、比重と施肥モードとに切替える施肥設定スイッチ７４と、増、減スイッチ７５、７６と、累計リセットスイッチ７７と、可変スイッチ７８等を配置する。可変スイッチ７４や施肥設定スイッチ７４等で比重モード、施設モードの切替えを行いながら、増、減スイッチ７５、７６の操作でこれら比重や、施肥量を変更調節して設定する構成としている。又、表示部７２には、これら比重や施肥量等を表示する液晶表示パネル７９や、これら切替表示させる表示切替スイッチ８０等が設けられる。前記施肥切替レバー７３は、ステアリングポスト８０上の上下前後のレバーガイド８１、８２に案内させて操作することができ、上下方向のレバーガイド８１に操作すれば前記比重や施肥量を増、減することができ、前後方向のレバーガイド８２に操作すれば比重変更と施肥量変更とのモード切替可能の構成とし、前記操作部７０における各スイッチ７４、７５、７６、７８等による操作と略同様の操作を行うことができる。このような施肥切替レバー７３は、ハンドル１０を把持したまま、走行しながらの運転姿勢で操作されるため、操作性、作業性を高めることができる。   The steering handle 10 is provided with an operation unit 70 at the center as shown in FIGS. 9 to 11, and a display unit 72 is provided at the front edge of the instrument panel 71 on the dashboard 9, The feed amount can be set. Further, a fertilization switching lever 73 that can be manually operated is provided between the operation unit 70 and the instrument panel 71. The operation unit 70 is provided with a fertilization setting switch 74 for switching between specific gravity and fertilization mode, increase / decrease switches 75 and 76, a cumulative reset switch 77, a variable switch 78, and the like. While the specific gravity mode and the facility mode are switched with the variable switch 74, the fertilizer setting switch 74, etc., the specific gravity and the fertilizer amount are changed and set by operating the increase / decrease switches 75 and 76. Further, the display unit 72 is provided with a liquid crystal display panel 79 that displays the specific gravity, fertilizer application amount, and the like, and a display changeover switch 80 that switches these displays. The fertilization switching lever 73 can be operated by being guided by the upper and lower lever guides 81, 82 on the steering post 80. When the vertical lever guide 81 is operated, the specific gravity and fertilization amount are increased or decreased. If the lever guide 82 in the front-rear direction is operated, the mode can be switched between a change in specific gravity and a change in fertilizer amount. The operation unit 70 has substantially the same operation as the switches 74, 75, 76, 78, etc. The operation can be performed. Since such a fertilization switching lever 73 is operated in a driving posture while traveling while holding the handle 10, operability and workability can be improved.

次に主として図１２に基づいて、前記ダッシュボード９の計器盤７１部に、前記表示部７２と共に操作部７０を配置して、ステアリングハンドル１０の内周部から見易くする構成としている。又、前記施肥切替レバー７３によって、苗植装置１７を昇降したり、植付爪２２を伝動する油圧、植付の作動を切替え可能とする構成とし、操作性を向上することができる。この施肥切替レバー７３は、フィンガレバーの操作形態とし、上側位置では施肥量と比重を切替える切替位置にし、下側位置では苗植装置１７を油圧昇降と、植付作動位置に切替可能な操作を電気的連動構成とする。   Next, mainly based on FIG. 12, the operation unit 70 is arranged together with the display unit 72 on the instrument panel 71 of the dashboard 9 so that it can be easily seen from the inner periphery of the steering handle 10. Further, the fertilizer switching lever 73 can be used to raise and lower the seedling planting device 17 and to switch between the hydraulic pressure for transmitting the planting claws 22 and the planting operation, thereby improving operability.
