【発明の属する技術分野】
この発明は、多条施肥機、又は多条播種機における施肥残留物、又は播種残留物を回収する残留物回収装置に関する。多条苗植機の施肥装置にも利用される。
【0002】
【発明が解決しようとする課題】
4条植形態の苗植機に同条基数の肥料繰出装置を横並びにして設け、各繰出装置の開口部に回収シャッタを設け、この回収シャッタを肥料搬送用の送風切替シャッタと連動させて、回収シャッタを開いて残量肥料を回収するときは、送風切替シャッタを回収側の回収管側へ送風するように切替連動する構成としている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開平9ー140229号公報(第1頁、図1)
【0004】
【課題を解決するための課題】
苗植機に装着する施肥装置等では、苗植装置の5〜6条植を越えた、7〜8条植形態以上の多条植形態に伴って、同条数の多条施肥形態の施肥装置が装着されることが多い。このような多条施肥形態、又は多条播種形態の施肥播種では、各繰出装置における回収シャッタを単一操作具で同時に開く形態にすると、回収される肥料等が回収管等の搬送経路内に詰り易くなる。又、繰出装置の数基の回収シャッタ毎に分割して操作しうるように複数の操作具を設ける形態では、施肥播種装置の横幅が広いため作業者の横移動による操作が面倒であり、部分的な操作忘れを生ずることも多い。
【0005】
【課題を解決するための手段】
請求項1に記載の発明は、肥料乃至種子を繰出す繰出装置1を横方向に多数基並設すると共に、各繰出装置1部には残留物を機外へ回収排出させる回収シャッタ2付きの回収口3を有して多条施肥又は多条播種する施肥播種機において、これら多数基のうち一部の回収シャッタ2Aと、全部の回収シャッタ2Bとに切替えて開閉操作する操作具4を設けたことを特徴とする残留物回収装置の構成とする。繰出装置1は機体の進行方向に対して横方向に多数基設されて、機体の進行に伴って各繰出装置1における肥料又は種子の繰出が行われると、多条施肥、又は多条播種が行われる。作業が終ると各繰出装置1に残留している残留物を機外へ取出して回収する。このとき各繰出装置1の回収シャッタ2を開くことによって各回収口3から残留物が回収される。この回収シャッタ2の操作として、操作具4によって各繰出装置1のうち一部の回収シャッタ2Aを同時に開閉したり、又、全部の回収シャッタ2Bを同時に開閉することができる。この操作具4の操作は、一部の回収シャッタ2Aと全部の回収シャッタ2Bとに切替えて開閉操作することができる。一部の繰出装置1に詰りを生じている場合や、各繰出装置1における残留量が多い場合等では、一部の回収シャッタ2A毎に開閉操作することができ、各繰出装置1の残留量が少い場合は、全部の回収シャッタ2Bを開閉操作できる。
【0006】
請求項2に記載の発明は、前記操作具4は、単一として一部の回収シャッタ2Aと、全部の回収シャッタ2Bとに切替えて開閉操作可能で、該繰出装置1並びの一側端部に設けたことを特徴とするものである。前記のような回収シャッタ2の開閉操作において、この操作具4の操作は全繰出装置1の横側端部において行われ、単一の操作具4を一部の回収シャッタ2A側と、全部の回収シャッタ2B側とに選択し切替え操作することができる。
【0007】
【発明の効果】
請求項1に記載の発明は、一部の回収シャッタ2Aと全部の回収シャッタ2Bとを切替選択して開閉する操作具4により、部分的な回収シャッタ2Aを開閉できるため回収中の肥料や種子等の詰りをなくすることができる。
【0008】
請求項2に記載の発明は、操作具4が繰出装置1並びの一側端部に設けられるため、多条広幅の作業装置に拘らず操作者が移動することなく一箇所で操作することができ、迅速、的確、容易である。また、一部の回収シャッタ2Aと全部の回収シャッタ2Bとは、同一操作具4によって切替操作されるものであるから、構成、及び操作は簡単であり、操作忘れも少くなり一層的確である。
【0009】
【発明の実施の形態】
この発明の実施例を図面に基づいて説明する。この施肥播種機は、図例では苗植機に施肥装置を装着して、多条苗植と多条施肥を行う形態としている。このように施肥は単独で行う形態か、又は苗植機や播種機と共に一体的に装着されて同時施肥を行いうる形態とするが、播種では単独で行う形態か、又は播種機と共に一体的に装着して同時作業を行う形態とする。この多条植苗植機の後部に施肥繰出装置1を搭載して、多条植形態の各苗植付土壌面部に施肥するものである。苗植機は、ハンドル5によって操作可能な前車輪6と後車輪7を有して、運転席8下のエンジン9によって伝動駆動して走行される四輪駆動走行形態のトラクタ10車体11を有し、この車体11の後側に昇降自在の平行リンク形態の昇降リンク12を有し、この昇降リンク10の後側に苗植装置13の苗植フレーム14部が連結される。この苗植装置13は、苗植フレーム14の下側部に土壌面を滑走しながら均平支持するフロート15と、マット状に育苗されたマット苗を収容して後下方へ繰出供給する横並形態の苗タンク16と、各苗タンク16から繰出されるマット苗を分離保持して下方の均平土壌面に植付ける苗植付爪17と等を配置して構成され、10条の多条植形態の苗植機を構成する。前記エンジン9を収容するエンジンルーム58を覆うエンジンカバー59の外周部には、操縦フロア60が設けられる。
【0010】
施肥装置は、車体11後部の運転席8後側に配置されて、肥料を収容するホッパー18と、この肥料を繰出す繰出装置1と、この繰出装置1の繰出ロール19の回転によって繰出された肥料を案内して土壌の施肥溝部へ搬送する施肥ホース20と、この各施肥ホース20部へ送風する送風ファン21、及び送風パイプ22と等からなり、車体11上の取付フレーム41に装着される。これら各ホッパー18、繰出装置1、繰出ロール19、及び送風パイプ22等は横方向に並設されて、多条植形態の苗植装置13の並び列に沿うように構成される。これら繰出装置1の並び列の横端部の送風パイプ22へ送風しうる送風ファン21を設けている。この送風パイプ22は繰出装置1の前側下部に沿うように設けられ、この繰出装置1の回収口3から排出される残留物(肥料)を受けて横方向へ搬送する回収パイプ23が、後側下部に沿って設けられ、送風ファン21側とは反対の側端部に回収ホース24が連結される。この回収ホース24は残留物回収時には回収袋や、コンテナ等にのぞませる。この回収パイプ23は前記送風パイプ22と共に送風ファン21に連通されて、これらの文岐部に設けられる切替弁25によって、施肥時は送風パイプ22側へ送風案内し、回収時は回収パイプ23側へ送風案内するように切替えるように構成している。
【0011】
前記各ホッパー18は、後側下部の開閉軸26の周りに回動させて、この下端のホッパ口27を繰出装置1上の繰出室28上にのぞませたり、開放することができる。シャッタ29はこのホッパ27部に設けられる。繰出ロール19はこの各ホッパ口27の直下に設けられて、ロール軸30によって軸装回転され、各繰出ロール19周面の繰出穴31に肥料を嵌合させながら直下の繰出口32へ繰出すことができる。33はこの回転周面に摺接する升切ブラシである。前記回収口3は各繰出室28の後側下部に設けられて、シャッタ軸34の周りに回動されて開閉される回収シャッタ2が設けられ、この回収シャッタ2を閉鎖状態では繰出室28内の肥料は繰出ロール19の回転によって繰出口32側へ繰出されるが、この回収シャッタ2を開くことによって繰出室28内の肥料を回収口3から回収パイプ23へ排出させる。
【0012】
このように繰出室28に残留する肥料を回収口3から回収パイプ23へ取出すには、この回収シャッタ2を開く。この回収シャッタ2の操作は一側端部の操作具4によって操作可能とする。各回収シャッタ2のシャッタ軸34にはピニオン35を有し、このピニオン35は横方向の操作具36に配置したピニオン37に噛合させる。この操作軸36の一端部を直接に、又は、操作軸39を介して横端部の操作盤38に軸受けして、レバー形態の操作具4で回動操作できる。操作軸39は36との間にピニオン40を噛合させて連動させる。
【0013】
ここで、多条施肥の繰出装置1のうち進行方向に向って左側略半分の繰出装置1の回収シャッタ2を2Aとし、右側略半分の繰出装置1の回収シャッタ2を2Bとして、各々略同じ軸芯上の操作軸36で同時にまとめて一体的に開閉操作できる形態としている。このため、操作盤38から遠い側の左側回収シャッタ2Aは操作軸36をそのまま操作盤38側延長でき難いため、ピニオン40と操作軸39を介して操作盤38側へ延長させている。しかも、これら左側回収シャッタ2Aの操作軸39には操作レバー4Aを設け、右側回収シャッタ2Bの操作軸36には操作レバー4Bを設けて、各々操作盤38に回動案内させて、回収口3を開閉に切替えることができる。
【0014】
これら各操作レバー4A,4Bは、回収シャッタ2A,2Bと共に前記送風ファン21の切替弁25をも切替連動する(図1、図6)。操作レバー4A,4Bには、リンクロッド42、ベルクランク43、及び切替ロッド44等を介して切替弁25と連動して、操作レバー4A,4Bによって回収シャッタ2A,2Bを開いて、残留物を回収パイプ23に排出案内させることにより、この切替弁25を送風パイプ22側から回収パイプ23側へ切替えるように構成している。又、この連動は、操作レバー4A,4Bの操作によって、先ず切替弁25を回収パイプ23側へ切替えて、この回収パイプ23内に送風させてから、回収シャッタ2A,2Bを開いて残留物を排出、円滑な回収搬送させるように構成することもできる。
【0015】
前記各繰出装置1の伝動構成は、ロール軸30の後側部を横方向に沿って設けられる駆動軸45にスプロケット46を有して、下方の車体11側のPTO軸からチエン連動される。この駆動軸45の外周には回転自在の筒軸47が配置されて、クラッチ48を介して一体回転される。各筒軸47にはギヤ49が配置されて、対向する繰出装置1のロール軸30のギヤ50と噛合連動する。筒軸47及びクラッチ48は繰出装置1の二基毎に設けられ、畦際作業のように一部の苗植条数の植付と共に繰出装置1の施肥を停止する場合は、この横端側のクラッチ48を切りにして、施肥条数幅を選定することができる。
【0016】
このような繰出装置1は、各回収口3の回収シャッタ2を閉鎖状態において、苗植装置13の苗植作業時に駆動されて、各繰出ロール19の回転とシャッタ29の開きによって、ホッパー18内の肥料が施肥ホース20に繰出されて、送風ファン21による送風が切替弁25によって送風パイプ22から各施肥ホース20へ案内され、苗植付部近くの土壌面へ施肥される。このような施肥作用後に各繰出装置1内に残留している肥料を取出掃除するときは、機体横端の操作盤38部において左右いずれか一方の操作レバー4Aを先ず操作して、左回収シャッタ2Aを開き、その後に右側の操作レバー4Bを操作して、右回収シャッタ2Bを開く。このため、左回収シャッタ2Aの開きと同時に切替弁25が回収パイプ23側へ送するように切替えられているため、この左側の各繰出室28の残留物は各回収口3から回収パイプ23内へ送出されて、該送風によってこの右側端の回収ホース24へ搬送される。このような回収作用中、又は回収作用後に右シャッタ2Bの開きによって、この右側の各繰出室28の残留物が同回収パイプ23内へ送出されて、回収ホース24側へ搬送される。
【0017】
このような多条施肥の繰出装置1の残留物の回収において、単一の送風ファン21や回収パイプ23を用いて回収搬送させることができ、構成、及び操作を簡単化できる。しかも、この回収操作は、多条全条を同時に回収搬送させないで一部毎に分けて、乃至一部毎にタイミングをずらせて搬送させるため、搬送開始時に残留物が一度にまとまって回収パイプ23に繰り出されることがなく、従ってこの回収パイプ23内に詰るようなことが少く、円滑で的確な回収を行うことができる。又、このような各部分的な回収操作は機体の左側、又は右側の一側端部において行うことができるため、作業者が多条の幅広い施肥土壌面を左右に移動することが少く、操作性を高めることができる。更には、この操作具4が回収パイプ23の終端の回収ホース24側に設けられるため、残留物の回収状況を見ながら回収作業できるため、操作性を高めることができる。
【0018】
次に、主として図9、図10に基づいて上例と異なる点は、前記左右の回収シャッタ2A,2Bを切替えて操作する操作具4を単一の操作レバー4C形態として、構成、操作を簡単化するものである。操作盤38には操作レバー4Cを案内するレバーガイドを、頭部のファンスイッチ部51と、二又分岐の全条回収部52と、右条回収部53とにより略h字形に形成する。繰出装置1及び回収シャッタ2等は左条回収部は5条で、右条回収部は3条で、合計全条回収部は8条の施肥形態としている。従って、各繰出装置1の回収シャッタ2を回動するための左右各操作軸36上のピニオン37も5箇、3箇の計8箇所に設けられる。左右の操作軸36間にはばね54で押圧されるドッグクラッチ形態の切替クラッチ55が設けられる。この切替クラッチ55は、操作レバー4Cの左右回動により入り切りされる。操作軸36の中芯部には芯軸56が軸方向に沿って移動自在に設けられ、この芯軸56の一端を操作レバー4Cに連結して押し引きでき、他端に切替クラッチ55の片側を回転自在に設けてこの操作レバー4Cをばね54に抗して右条回収部53側に操作するときは、この切替クラッチ55を切りにして右条回収シャッタ2Bのみを開くことができ、左条回収部52側へ操作するときは、この切替クラッチ55を入りにして全条回収シャッタ2A,2Bを略同時に開くことができる。57は操作レバー4Cの基部を支持案内する案内溝で、操作レバー4Cは、該芯軸56の周りに前後回動できると共に、この案内溝57の周りに左右回動される。又、この操作レバー4Cは、レバーガイドのファンスイッチ51を回動されることによって送風ファン21のモータスイッチをONして駆動するものであり、続く回動によって前記のように全条回収部52又は右条回収部53へ回動操作して回収形態を切替え選択する。
【0019】
次に、主として図11に基づいて上例と異なる点は、前記回収シャッタ2を操作する操作具4を、前記繰出装置1の後側部で、ホッパー18の後側反転位置Dと、この下方の回収パイプ23との間の間隔部Eに対向して設けることにより、狭い間隔部Eにこれら回収操作機構を配置してコンパクト化できる。操作具4は操作軸36周りに上下に回動可能で、最上位置では施肥位置Fとして、回収シャッタ2を閉鎖するが、下動操作して部分回収位置Gにすると一部分の回収シャッタ2のみ開き更に最下位置Hでは全部の回収シャッタ2を開いて回収させる。
【0020】
次に、図12、図13に基づてい上例と異なる点は、前記車体11の操縦フロア60の下側に、前記エンジンルーム58と送風ファン21の吸気口61との間を連結する吸気ダクト62を構成する。63は吸気ダクト62と吸気口61との間を連結する連結ダクトである。操縦フロア60は硬質の樹脂製加工されるが、吸気ダクト62はこの操縦フロア60の下面に同樹脂材によって一体的成形することができる。又、吸気ダクト62を独立成形して操縦フロア60の下面に取付けることもできる。この吸気ダクト62の操縦フロア60端から突出部分は連結ダクト63として、吸気ダクト62に連結する。このような構成によって、送風ファン21の吸気としてエンジンルーム58内の熱風を吸引して、エンジン9の冷却効率を高め、吸気ダクト62の構成を簡潔にすることができる。
【0021】
次に、主として図14に基づいて、上例と異なる点は、前記繰出装置1の繰出口32から繰出される肥料を受けて搬送させる施肥ホース20への送風部である送風パイプ22を、ゴム製の弾性ホース形態として、この送風パイプ22の各施肥ホース20への分岐口64と対向する分岐対向部65を、押当具66で押圧変形させて、この送風パイプ22内を流れる風向きや流速等を変化させることにより、各分岐口64へ分岐される風量を調節するものである。押当具66は前記取付フレーム41の一部に対して前後移動調節可能とするブラケット67によって取付けられる。このように送風パイプ22の弾性を利用して外周分から変形させて、各施肥ホース20への分岐風量を均一に調節するため、構成、調節が簡単であり、安価な構成とすることができる。

Each of the hoppers 18 can be rotated around an opening / closing shaft 26 at the lower rear side so that the hopper port 27 at the lower end can be viewed or opened on a feeding chamber 28 on the feeding device 1. The shutter 29 is provided in the hopper 27. The feeding rolls 19 are provided directly below the hopper ports 27, and are rotated by a roll shaft 30 to feed the fertilizer to the feeding outlets 32 immediately below while fitting the fertilizer into the feeding holes 31 on the peripheral surface of the respective feeding rolls 19. be able to. Reference numeral 33 denotes a cutting brush that slides on the rotating peripheral surface. The collecting port 3 is provided at the lower rear side of each feeding chamber 28, and is provided with a collecting shutter 2 which is rotated around a shutter shaft 34 and opened / closed. Is fed to the outlet 32 by the rotation of the feed roll 19. By opening the collection shutter 2, the fertilizer in the feeding chamber 28 is discharged from the collection port 3 to the collection pipe 23.
[0012]
In order to take out the fertilizer remaining in the feeding chamber 28 from the collection port 3 to the collection pipe 23, the collection shutter 2 is opened. The operation of the collection shutter 2 can be operated by the operation tool 4 at one end. The shutter shaft 34 of each recovery shutter 2 has a pinion 35, and this pinion 35 is engaged with a pinion 37 arranged on a lateral operation tool 36. One end of the operation shaft 36 can be directly or directly supported on the operation panel 38 at the lateral end via the operation shaft 39, and can be rotated by the lever-shaped operation tool 4. The operation shaft 39 is interlocked with the pin 36 by meshing the pinion 40 therewith.
[0013]
Here, in the feeding device 1 for multi-row fertilizer application, the collection shutter 2 of the feeding device 1 on the substantially left half in the traveling direction is set to 2A, and the collection shutter 2 of the feeding device 1 on the right half is set to 2B. The opening and closing operation can be performed simultaneously and integrally by the operation shaft 36 on the shaft core. For this reason, since it is difficult to extend the operation shaft 36 to the left recovery shutter 2A on the far side from the operation panel 38 as it is, it is extended to the operation panel 38 via the pinion 40 and the operation shaft 39. Moreover, an operation lever 4A is provided on the operation shaft 39 of the left recovery shutter 2A, and an operation lever 4B is provided on the operation shaft 36 of the right recovery shutter 2B. Can be switched between open and closed.
[0014]
These operating levers 4A and 4B switch the switching valve 25 of the blower fan 21 together with the collecting shutters 2A and 2B (FIGS. 1 and 6). The operation levers 4A and 4B are linked with the switching valve 25 via a link rod 42, a bell crank 43, a switching rod 44, and the like to open the collection shutters 2A and 2B with the operation levers 4A and 4B to remove the residue. By causing the recovery pipe 23 to guide the discharge, the switching valve 25 is configured to be switched from the blower pipe 22 side to the recovery pipe 23 side. In addition, the interlocking is performed by first switching the switching valve 25 to the collection pipe 23 side by operating the operation levers 4A and 4B to blow air into the collection pipe 23, and then opening the collection shutters 2A and 2B to remove the residue. It can also be configured to discharge and smoothly carry and convey.
[0015]
The transmission structure of each of the feeding devices 1 has a sprocket 46 on a drive shaft 45 provided on the rear side of the roll shaft 30 along the lateral direction, and is chain-coupled from a PTO shaft on the lower vehicle body 11 side. A rotatable cylinder shaft 47 is disposed on the outer periphery of the drive shaft 45, and is integrally rotated via a clutch 48. A gear 49 is disposed on each of the cylinder shafts 47 and meshes with the gear 50 of the roll shaft 30 of the feeding device 1 facing the gear 49. The cylinder shaft 47 and the clutch 48 are provided for every two units of the feeding device 1, and when the fertilization of the feeding device 1 is stopped together with the planting of a part of the number of seedlings as in the ridge work, the lateral end side is used. By disengaging the clutch 48, the width of the number of fertilizer application strips can be selected.
[0016]
Such a feeding device 1 is driven during the seedling operation of the seedling plant 13 with the collection shutter 2 of each collection port 3 closed, and the rotation of each feeding roll 19 and the opening of the shutter 29 causes the inside of the hopper 18 to move. Is fed to the fertilizer hose 20, and the air blown by the blower fan 21 is guided to each fertilizer hose 20 from the blower pipe 22 by the switching valve 25, and is fertilized on the soil surface near the seedling planting portion. To remove and clean the fertilizer remaining in each feeding device 1 after such a fertilizing operation, the left recovery shutter is first operated by operating one of the left and right operation levers 4A on the operation panel 38 at the lateral end of the machine body. 2A, and then operate the right operation lever 4B to open the right recovery shutter 2B. For this reason, since the switching valve 25 is switched so as to be sent to the collection pipe 23 simultaneously with the opening of the left collection shutter 2 </ b> A, the residue in each delivery chamber 28 on the left side passes from each collection port 3 to the inside of the collection pipe 23. And is conveyed to the collection hose 24 at the right end by the blowing. During or after the recovery operation, the right shutter 2B is opened, and the residue in each of the right delivery chambers 28 is sent out into the recovery pipe 23 and is conveyed to the recovery hose 24 side.
[0017]
In the collection of the residue of the multi-row fertilizer feeding device 1, the single blower fan 21 and the collection pipe 23 can be used to collect and convey the residue, thereby simplifying the configuration and operation. In addition, in this collection operation, since the multi-story is not collected and conveyed at the same time, but is divided into parts, or conveyed at a different timing for each part, the residue is collected at once at the start of conveyance, and the collection pipe 23 is collected. Therefore, the collection pipe 23 is less likely to be clogged, and smooth and accurate collection can be performed. In addition, since such a partial recovery operation can be performed at one end of the left side or the right side of the machine, the operator is less likely to move left and right over a wide variety of fertilized soil surfaces. Can be enhanced. Furthermore, since the operating tool 4 is provided on the side of the collecting hose 24 at the end of the collecting pipe 23, the collecting operation can be performed while monitoring the collecting state of the residue, so that the operability can be improved.
[0018]
Next, a point different from the above example mainly based on FIGS. 9 and 10 is that the operation tool 4 for switching and operating the left and right recovery shutters 2A and 2B is configured as a single operation lever 4C to simplify the configuration and operation. It becomes something. On the operation panel 38, a lever guide for guiding the operation lever 4C is formed in a substantially h-shape by a fan switch portion 51 on the head, a bifurcated all-stroke recovery portion 52, and a right-stripe recovery portion 53. The feeding device 1 and the collecting shutter 2 have a left strip collecting section of 5 strips and a right strip collecting section of 3 strips. Therefore, pinions 37 on each of the left and right operation shafts 36 for rotating the collection shutter 2 of each feeding device 1 are also provided at five and three pins, for a total of eight locations. A dog clutch type switching clutch 55 pressed by a spring 54 is provided between the left and right operation shafts 36. The switching clutch 55 is turned on and off by turning the operation lever 4C left and right. A core shaft 56 is provided at the center of the operation shaft 36 so as to be movable in the axial direction. One end of the core shaft 56 can be connected to the operation lever 4C and pushed and pulled. When the operating lever 4C is operated to the right-hand collecting portion 53 side against the spring 54, the switching clutch 55 is disengaged to open only the right-hand collecting shutter 2B. When the operation is performed toward the strip collecting section 52, the switching clutch 55 is engaged so that all the strip collecting shutters 2A and 2B can be opened substantially simultaneously. Reference numeral 57 denotes a guide groove for supporting and guiding the base of the operation lever 4C. The operation lever 4C can rotate back and forth around the core shaft 56, and can also turn left and right around the guide groove 57. The operation lever 4C is driven by turning on the motor switch of the blower fan 21 by turning the fan switch 51 of the lever guide, and by rotating the fan switch 51 subsequently, the whole-row collection unit 52 is rotated as described above. Alternatively, the collection mode is switched and selected by rotating the right collection section 53.
[0019]
Next, the point different from the above example mainly based on FIG. 11 is that the operating tool 4 for operating the recovery shutter 2 is located at the rear side of the feeding device 1 at the rear inversion position D of the hopper 18 and at the lower side. The collection operation mechanism is disposed in the narrow space E so that it can be made compact. The operation tool 4 can be turned up and down around the operation shaft 36. At the uppermost position, the collection shutter 2 is closed at the fertilization position F. However, when the lowering operation is performed to the partial collection position G, only a part of the collection shutter 2 is opened. Further, at the lowermost position H, all the collection shutters 2 are opened and collected.
[0020]
Next, the difference from the above example based on FIGS. 12 and 13 is that the intake air connecting the engine room 58 and the intake port 61 of the blower fan 21 is located below the control floor 60 of the vehicle body 11. The duct 62 is constituted. 63 is a connection duct that connects between the intake duct 62 and the intake port 61. Although the control floor 60 is made of hard resin, the intake duct 62 can be integrally formed on the lower surface of the control floor 60 with the same resin material. Further, the intake duct 62 can be formed independently and attached to the lower surface of the control floor 60. A portion of the intake duct 62 protruding from the control floor 60 end is connected to the intake duct 62 as a connection duct 63. With such a configuration, the hot air in the engine room 58 is sucked as the intake air of the blower fan 21, the cooling efficiency of the engine 9 is increased, and the configuration of the intake duct 62 can be simplified.
[0021]
Next, based mainly on FIG. 14, the point different from the above example is that the blowing pipe 22 which is a blowing section to the fertilizing hose 20 for receiving and transporting the fertilizer fed from the feeding port 32 of the feeding device 1 is made of rubber. And a branch opposing portion 65 of the blow pipe 22 facing the branch port 64 to each fertilizing hose 20 is pressed and deformed by a pressing tool 66 so that the wind direction and the flow rate flowing through the blow pipe 22 are changed. The amount of air to be branched to each branch port 64 is adjusted by changing the above. The pressing tool 66 is attached to a part of the attachment frame 41 by a bracket 67 that can be adjusted to move back and forth. As described above, since the air blowing pipe 22 is elastically deformed from the outer periphery and the amount of branch air to each fertilizing hose 20 is uniformly adjusted, the configuration and adjustment are simple, and a low-cost configuration can be achieved.
