【0006】
従って、請求項1記載の発明は、車体3の前後に左右一対の前輪4及び後輪5を設け、車体3の上前部に操作ボックス6及びステアリングハンドル7を有する操縦装置を設け、該操縦装置の後側に操縦席9を設け、車体3の後方部で操縦席9より後側に位置して昇降可能な苗植付部8を設け、該苗植付部8の前側には肥料を圃場に散布する施肥装置1の左右の肥料収容ホッパー14と肥料繰出部15と肥料の搬送を案内する案内管16と該案内管16に圧風を送給する施肥エアチャンバー17と該施肥エアチャンバー17に圧風を送給するブロワー18とを設け、肥料繰出部15を肥料収容ホッパー14の下側に設け、肥料繰出部15の繰出ロール15aが回転することにより粒状肥料を繰出口15bを介して案内管16に供給し、案内管16に供給された粒状肥料が施肥エアチャンバー17からの圧風により案内管16及び肥料移送管19を介して該肥料移送管19終端に設けられた施肥部20へ搬送されて圃場に散布される構成としたので、施肥装置1の肥料繰出部15は、肥料収容ホッパー14の下側に設けられ、繰出ロール15aが回転することにより粒状肥料が繰出口15bを介して案内管16に供給される。そして、案内管16に供給された粒状肥料は、施肥エアチャンバー17からの圧風により該案内管16及び肥料移送管19を介して該肥料移送管19終端に設けられた施肥部20へ搬送されて圃場に散布される。

また、繰出ロール15aの前側に肥料収容ホッパー14の粒状肥料を回収する肥料回収管23への肥料取出口37を設け、切替レバー39の操作により軸39a回りに揺動して先端が繰出ロール15aの外周面に接触及び退避するブラシ38を設け、該ブラシ38の先端が繰出ロール15aの外周面に接触したときは肥料収容ホッパー14の肥料を繰出ロール15aの回転により繰出口15bへ繰り出す繰出状態(ロ)になり、ブラシ38の先端が繰出ロール15aの外周面から退避したときは肥料収容ホッパー14の肥料を繰出ロール15aを介さずに下方に落下させる排出状態(イ)になる構成とし、繰出ロール15aの肥料排出側には、前記排出状態(イ)のとき、肥料が繰出側に落下しないよう阻止する隔壁41を繰出ロール15aの外周面に接するように設け、該隔壁41に排出時の肥料を流下案内させる流下案内壁42を連設し、該流下案内壁42と隔壁41とを樹脂材にて一体成型し、隔壁41の上端側基部に切込部41aを設け、該切込部41aを支点として該隔壁41の先端側が前後方向に揺動変位する構成とし、前記ブラシ38の一側部には隔壁41の上端を押圧する押圧突子40をブラシと一体的に揺動するよう設けて、ブラシ38を繰出状態(ロ)に切り替えると、押圧突子40が隔壁41の上端を押圧して、隔壁41は切込部41aを支点として繰出ロール15aから離間する方向に揺動変位し、ブラシ38を排出状態(イ)に切り替えると、押圧突子40による押圧が解除されて、隔壁41は切込部41aを支点としてロール周面に接触する方向に揺動復帰する。
【0007】
請求項2記載の発明は、左右の肥料収容ホッパー14間に該左右の肥料収容ホッパー14に通じる肥料予備タンク33を設け、左右の肥料収容ホッパー14及び肥料予備タンク33の上部には蝶番34を介して揺動開閉する開閉カバー35,36を設けたことを特徴とする請求項1記載の施肥装置付苗植機とした。
【0008】
従って、請求項1記載の発明の作用に加えて、左右の肥料収容ホッパー14間に該左右の肥料収容ホッパー14に通じる肥料予備タンク33を設け、左右の肥料収容ホッパー14及び肥料予備タンク33の上部には蝶番34を介して揺動開閉する開閉カバー35,36を設けたので、肥料予備タンク33内に収容される予備肥料を隣接の左右のホッパー14内へ掻き寄せ供給することができる。
【0009】
【発明の効果】
請求項1記載の発明は、車体3の前後に左右一対の前輪4及び後輪5を設け、車体3の上前部に操作ボックス6及びステアリングハンドル7を有する操縦装置を設け、該操縦装置の後側に操縦席9を設け、車体3の後方部で操縦席9より後側に位置して昇降可能な苗植付部8を設け、該苗植付部8の前側には肥料を圃場に散布する施肥装置1の左右の肥料収容ホッパー14と肥料繰出部15と肥料の搬送を案内する案内管16と該案内管16に圧風を送給する施肥エアチャンバー17と該施肥エアチャンバー17に圧風を送給するブロワー18とを設け、肥料繰出部15を肥料収容ホッパー14の下側に設け、肥料繰出部15の繰出ロール15aが回転することにより粒状肥料を繰出口15bを介して案内管16に供給し、案内管16に供給された粒状肥料が施肥エアチャンバー17からの圧風により案内管16及び肥料移送管19を介して該肥料移送管19終端に設けられた施肥部20へ搬送されて圃場に散布される構成としたので、施肥装置1の肥料繰出部15は、肥料収容ホッパー14の下側に設けられ、繰出ロール15aが回転することにより粒状肥料が繰出口15bを介して案内管16に供給される。そして、案内管16に供給された粒状肥料は、施肥エアチャンバー17からの圧風により該案内管16及び肥料移送管19を介して該肥料移送管19終端に設けられた施肥部20へ搬送されて圃場に散布される。
また、肥料収容ホッパー14内の残留肥料を回収する肥料回収管23を前記施肥エアチャンバー17と一体的に構成し、該肥料回収管23の始端側をブロワー18の吐出口とエア切替部24を介して接続し、肥料回収管23の終端側に下方に屈曲した屈曲管25を接続して揺動開閉自在な開閉蓋28を設けた下向きの肥料回収口26を設けたので、該肥料回収口26から出てくる粒状肥料を袋や容器で受けて肥料を回収する。
また、エア切替部24に施肥エアチャンバー17側と肥料回収管23側とにブロワー18の圧風を切替可能なエア切替弁27を設け、該エア切替弁27を操作するエア切替操作レバー29の操作により、圧風を施肥エアチャンバー17へ送給するようにエア切替弁27を操作すると前記開閉蓋28を閉じ、圧風を肥料回収管23へ送給するようにエア切替弁27を操作すると前記開閉蓋28を開く操作連動機構30を設けたので、エア切替操作レバー29によりエア切替弁27を操作して、通常の施肥作業時には圧風を施肥エアチャンバー17へ送給し、作業終了時等肥料収容ホッパー14内の残留肥料を回収する時には、圧風を肥料回収管23へ送給する。このエア切替操作レバー29の操作により、操作連動機構30を介して圧風を施肥エアチャンバー17へ送給するようにエア切替弁27を操作すると前記開閉蓋28を閉じ、圧風を肥料回収管23へ送給するようにエア切替弁27を操作すると前記開閉蓋28を開き、互いに施肥装置1の左右反対側にあるエア切替弁27と開閉蓋28との切替操作を容易に行える。
また、繰出ロール15aの前側に肥料収容ホッパー14の粒状肥料を回収する肥料回収管23への肥料取出口37を設け、切替レバー39の操作により軸39a回りに揺動して先端が繰出ロール15aの外周面に接触及び退避するブラシ38を設け、該ブラシ38の先端が繰出ロール15aの外周面に接触したときは肥料収容ホッパー14の肥料を繰出ロール15aの回転により繰出口15bへ繰り出す繰出状態(ロ)になり、ブラシ38の先端が繰出ロール15aの外周面から退避したときは肥料収容ホッパー14の肥料を繰出ロール15aを介さずに下方に落下させる排出状態(イ)になる構成とし、繰出ロール15aの肥料排出側には、前記排出状態(イ)のとき、肥料が繰出側に落下しないよう阻止する隔壁41を繰出ロール15aの外周面に接するように設け、該隔壁41に排出時の肥料を流下案内させる流下案内壁42を連設し、該流下案内壁42と隔壁41とを樹脂材にて一体成型し、隔壁41の上端側基部に切込部41aを設け、該切込部41aを支点として該隔壁41の先端側が前後方向に揺動変位する構成とし、前記ブラシ38の一側部には隔壁41の上端を押圧する押圧突子40をブラシと一体的に揺動するよう設けて、ブラシ38を繰出状態(ロ)に切り替えると、押圧突子40が隔壁41の上端を押圧して、隔壁41は切込部41aを支点として繰出ロール15aから離間する方向に揺動変位し、ブラシ38を排出状態(イ)に切り替えると、押圧突子40による押圧が解除されて、隔壁41は切込部41aを支点としてロール周面に接触する方向に揺動復帰する。
【0010】
従って、作業終了時等に肥料収容ホッパー内の残留肥料を回収するときに、操作が容易に行えるようにした施肥装置付苗植機を提供することができ、適切に課題を解消することができる。
【0011】
請求項2記載の発明は、請求項1記載の発明の効果に加えて、左右の肥料収容ホッパー14間に該左右の肥料収容ホッパー14に通じる肥料予備タンク33を設け、左右の肥料収容ホッパー14及び肥料予備タンク33の上部には蝶番34を介して揺動開閉する開閉カバー35,36を設けたので、肥料予備タンク33内に収容される予備肥料を隣接の左右のホッパー14内へ掻き寄せ供給することができ、肥料予備タンクから左右の肥料収容ホッパーへの肥料供給が容易に行える。
【0012】
【発明の実施の形態】
この発明の実施例を図面に基づき説明する。
図1及び図2は、乗用型の田植機に粒状の肥料を圃場に散布する施肥装置1が装着された施肥装置付乗用型田植機2を示すものであり、この乗用型田植機2は、車体3の前後に走行車輪としての左右一対の前輪4,4及び後輪5,5が架設されている。車体上前部に操作ボックス6及びステアリングハンドル7等を有する操縦装置が設置され、車体後方部には昇降可能な苗植付部8が装備されている。
【0013】
操縦装置の後側に操縦席9が設置され、操縦席の下側に田植機の各部に動力を伝達するエンジン10が搭載されている。
苗植付部8は、左右に往復動する苗載タンク11、1株分の苗を切取って土中に植込む4条分の苗植付装置12、苗植付面を整地するフロート13等からなる。
【0014】
施肥装置1は、苗植付部8の前方に設けられていて、圃場に散布する粒状肥料を収容する肥料収容ホッパー14と各条毎の肥料繰出部15…と肥料の搬送を案内する各条毎の案内管16…と該案内管16…に圧風を送給する施肥エアチャンバー17と該施肥エアチャンバー17に圧風を送給するブロワー18等からなる構成である。
【0015】
肥料繰出部15…は、肥料収容ホッパー14の下側に設けられ、繰出ロール15a…が回転することにより所定量毎に肥料を各条の繰出口15bを介して前記案内管16…に供給されるようになっている。
各案内管16…に供給された粒状肥料は、施肥エアチャンバー17からの圧風により該案内管16…、肥料移送管19…を介して該肥料移送管19…終端に設けられた施肥部20…へ搬送されて圃場に散布される。
【0016】
施肥部20…は、作溝器21を備えて構成され、前記肥料移送管19…とブーツ22…により接続され、苗植付部8による各条の圃場の苗植付位置の側部であって作溝された溝内に肥料が供給されるようになっている。
ホッパー14内の残留肥料を回収する肥料回収管23が前記施肥エアチャンバー17と一体的に構成して設けられている。
【0017】
肥料回収管23は、始端側がブロワー18の吐出口とエア切替部24を介して接続され、ブロワー18からの圧風を該肥料回収管23に送給可能に構成している。回収管23の終端側には下方に屈曲した屈曲管25を接続して下向きの肥料回収口26を設け、該回収口26から出てくる粒状肥料を袋や容器等で受けて肥料を回収するようになっている。
【0018】
前記エア切替部24には、施肥エアチャンバー17側と肥料回収管23側とにエア切替可能なエア切替弁27を備えている。要するに、通常作業時にはエア切替弁27を肥料回収管23側に回動させて圧風を施肥エアチャンバー17へ送給するようにし、作業終了時等肥料収容ホッパー14内の残留肥料を回収するときには、エア切替弁27を施肥エアチャンバー17側に回動させて圧風を肥料回収管23へ送給するようにしている。
【0019】
前記肥料回収管23の回収口26には軸28a周りに揺動開閉自在な開閉蓋28が設けられている。開閉蓋28は、残留肥料回収時は開けておき、そして、この回収作業が終わると閉めておくものである。また、この開閉蓋28は、エア切替弁27を切替操作するためのエア切替操作レバー29の操作により、操作アーム30a、ワイヤー30b、揺動アーム30c等からなる操作連動機構30を介して開閉できるように関連構成している。従来はエア切替弁と開閉蓋とを別個に操作しなければならず、互いに施肥装置の左右反対側にあるエア切替弁と開閉蓋とを操作するのが煩わしいものとなっていたが、本実施例の構成によりこの切替操作を容易に行える。なお、31は肥料流下案内体を示す。
【0020】
図2及び特に図3の平面図で示すように、前記肥料収容ホッパー14及び肥料繰出部15は、機体の後部で操縦席9と苗植付部8との間にあって左右に分離して配設した構成としている。そして、この左右の肥料収容ホッパー14L1,14L2及び14R3,14R4は、前端が操縦席9の後端9cより前側で、該肥料収容ホッパー14L2,14R3の左右方向内側端が操縦席9の左右方向の外側端9a,9bより内側に位置するよう配置している。
【0021】
従って、かかる配置構成によれば、機体全長を短くでき、全幅もコンパクトになり、しかも、軽量化及びコストダウンが可能となる。
また、特に図3に示す実施例では、前記操縦席9と苗植付部との間で、且つ、前記左右の肥料収容ホッパー14(14L2),14(14R3)間の空間内において作業ステップ32を設けた構成としている。従って、作業者はこの作業ステップ32の位置から各苗載タンク12内への苗補給ができるので、作業性が極めて良くなり、能率も向上することになる。
【0022】
更に、図4に示す実施例では、この左右の肥料収容ホッパー14,14は、少なくとも、苗植付部最下降時において該ホッパー上端が側面視で前傾姿勢にある苗載タンク11の傾斜延長線S上より下方に位置するように配置してある。これにより、苗補給時には、ホッパー上端が邪魔にならず、苗載タンク11上へ苗をスムースに滑り込ませることができる。
【0023】
図5及び図6に示す実施例では、左右の肥料収容ホッパー14,14間には、該左右のホッパー14,14に通じる肥料予備タンク33を配設した構成としている。肥料予備タンク33内に収容される予備肥料は隣接の左右ホッパー14,14内へ掻き寄せ供給することができる。ホッパー14,14内の肥料が所定量以下に減少すると、予備タンク内の肥料を、例えば螺旋体等で自動的に送り込み供給するようにすることもできる。なお、前記肥料収容ホッパー14,14及び肥料予備タンク33の上部には、蝶番34を介して揺動開閉する開閉カバー35,36が設けられている。
【0024】
前記繰出ロール15aの前側には作業終了後等にホッパー14及び肥料繰出部15に残留する粒状肥料を取り出し回収するための肥料回収管23への肥料取出口37を設けている。
繰出ロール15aの外周面には、回転方向の一定角度毎に繰出溝Q…が設けられてあり、その繰出溝Q…にホッパー14から落下供給される肥料を溜めて該繰出ロール15aを駆動回転することによって繰出口15bへ繰り出される構成となっている。そして、この繰出ロール15aの外周側近傍にはホッパー14からの肥料を繰出ロール15aを介さずに下方に落下させる排出状態(排出側経路(イ))と繰出ロール15aの回転により下方に繰り出す繰出状態(繰出側経路(ロ))とに切り替えるブラシ38が設けられている。このブラシ38は、切替レバー39の回動操作により軸39a回りに揺動可能な構成になっている。要するに、切替レバー39の回動操作により該ブラシの先端が繰出ロールの外周面に接触したり、ロールの外周面から退避したりする構成としている。また、ブラシ38の一側部には後記する隔壁41の繰出ロールに対する接触抵抗度合を調整するための押圧突子40が該ブラシと一体的に揺動するよう設けられている。
【0025】
繰出ロール15aの肥料排出側には、繰出ロール15aを介さずに肥料を落下させるとき、肥料が繰出側に落下しないよう阻止するための隔壁41が繰出ロール15aの外周面に接するように設けられている。隔壁41には排出時の肥料を流下案内させるための流下案内壁42が連設され、この流下案内壁42と隔壁41とは樹脂材によって一体成型された構成としている。そして、前記隔壁41は、この隔壁の上端側基部(流下案内壁42の上端部)に切込部41aが設けられ、この切込部41aを支点として該隔壁41の先端(下端)側が前後方向に揺動変位するようにして、前記繰出ロール15aに対する接触抵抗度合を変化させる構成としている。
【0026】
従って、前記ブラシ38を繰出状態(ロ)側に切り替える(図8参照)と、押圧突子40が隔壁41の上端を押圧することになるので、隔壁41は切込部41aを支点としてロールから離間する方向に揺動変位し繰出ロール15aに対する接触抵抗度合が小さくなる。
【0027】
また、ブラシ38を排出状態(イ)側に切り替える(図9参照)と、押圧突子40による押圧状態が解除されるので、隔壁41は切込部41aを支点としてロール周面に接触する方向に揺動復帰し繰出ロール15aに対する接触抵抗度合が大きくなる。
【0028】
図10に示す実施例では、ブラシ38と隔壁41を、リンク43,44及びロッド45等からなるリンク連動機構を介して関連作動させるべく構成している。すなわち、切替レバー39でもってブラシ38を繰出状態側に切り替える(実線状態)と、隔壁41は、リンク43、ロッド45、リンク44を介して支点軸46回りにロール15aから離間する方向に揺動変位(実線状態)する。また、ブラシ38を排出状態側に切り替える(仮想線状態)と、隔壁41は、リンク連動機構43、45、44を介して支点軸46回りに揺動復帰しロール周面に接触する状態(仮想線状態)となる。従来はブラシと隔壁とを別個に操作しなければならず、この操作が煩わしいものとなっていたが、本実施例の構成によると切替レバー39によりブラシ38と隔壁41とを共に操作できるので、このブラシ38と隔壁41との切替操作を容易に行える。

  On the fertilizer discharge side of the feeding roll 15a, when the fertilizer is dropped without going through the feeding roll 15a, a partition wall 41 for preventing the fertilizer from falling on the feeding side is provided so as to contact the outer peripheral surface of the feeding roll 15a. ing. The partition wall 41 is provided with a flow guide wall 42 for guiding the flow of fertilizer during discharge. The flow guide wall 42 and the partition wall 41 are integrally formed of a resin material. The partition wall 41 is provided with a cut portion 41a at the upper end side base portion (upper end portion of the flow guide wall 42) of the partition wall, and the front end (lower end) side of the partition wall 41 is a front-rear direction with the cut portion 41a as a fulcrum. The degree of contact resistance with respect to the feeding roll 15a is changed so as to swing and displace.
[0026]
  Therefore, when the brush 38 is switched to the extended state (b) side (see FIG. 8), the pressing protrusion 40 presses the upper end of the partition wall 41, so that the partition wall 41 is removed from the roll with the notch 41a as a fulcrum. It swings and displaces in the direction to separate, and the contact resistance degree with respect to the supply roll 15a becomes small.
[0027]
  Further, when the brush 38 is switched to the discharge state (a) side (see FIG. 9), the pressing state by the pressing protrusion 40 is released, so that the partition wall 41 comes into contact with the roll peripheral surface with the notch 41a as a fulcrum. And the degree of contact resistance with respect to the feeding roll 15a increases.
[0028]
  In the embodiment shown in FIG. 10, the brush 38 and the partition wall 41 are configured to be related to each other via a link interlocking mechanism including links 43 and 44, a rod 45, and the like. That is, when the brush 38 is switched to the extended state with the switching lever 39 (solid line state), the partition wall 41 swings around the fulcrum shaft 46 in a direction away from the roll 15a via the link 43, the rod 45, and the link 44. Displace (solid line state). Further, when the brush 38 is switched to the discharge state side (virtual line state), the partition wall 41 returns to swing around the fulcrum shaft 46 via the link interlocking mechanisms 43, 45, and 44 (virtual line state). Line state). Conventionally, the brush and the partition must be operated separately, and this operation has been troublesome, but according to the configuration of the present embodiment, the brush 38 and the partition 41 can be operated together by the switching lever 39. Switching operation between the brush 38 and the partition wall 41 can be easily performed.
[0029]
  Another embodiment shown in FIGS. 11 to 14 will be described.
  The fertilizer application device 1 shown in FIGS. 11 and 12 includes a fertilizer storage hopper 14 for storing granular fertilizers to be dispersed in a field, a fertilizer feed unit 15 for each strip, and a guide tube 16 for each strip for guiding the transport of the fertilizer. The fertilizer air chamber 17 feeds compressed air to the guide pipes 16 and the blower 18 feeds pressurized air to the fertilized air chamber 17.
[0030]
  As shown in the figure, when the blower 18 is directly connected to the engine 10 via the belt transmission 47, the mechanism is simple and suitable for weight reduction, but on the other hand, the air volume is extremely high depending on the engine speed. There are changing problems.
  The amount of air necessary for fertilization can be sufficiently secured by the number of revolutions at idling, so it is necessary to suppress changes in the blower air amount due to changes in engine speed. Therefore, in this embodiment, the fertilizer air chamber 17 is provided with a pressure valve (pressure reducing valve) 48 or a pressure valve 49 or both pressure valves 48 and 49 that open when the air volume exceeds a certain level and allows excess air to escape. It is configured. The pressure valve 48 shown in FIG. 13 is configured to open and close the weight by wind pressure, and the pressure valve 49 shown in FIG. 14 is configured to swing and open the weight by wind pressure. Thereby, an appropriate wind pressure can be obtained in the fertilization air chamber 17 without being greatly affected by the engine speed.
