従来、この種の乗用型田植機では、ホッパに入った農用粉粒体を繰り出し部から作溝器へ供給するホースが周辺の部材(例えば後輪)と干渉しないようにするため、ホースの配管経路の規制するホース支持部材が備えられている。例えば、特許文献1におけるホースガイドフレーム(137),挟持バンド(138),支持アーム(140)のように植付装置に固定された部材でホースを植付装置に係止したり、同じく特許文献1におけるホース連結体(141)や左右係止部(142)のように隣接するホースの特定位置においてそれぞれを結束部材により相互連結したりしているものがある。
特開2000−152706号公報(図20)
Conventionally, in this type of riding type rice transplanter, the hose for supplying the agricultural granular material contained in the hopper to the grooving device from the feeding portion is prevented from interfering with surrounding members (for example, rear wheels). A hose support member that regulates the path is provided. For example, the hose is locked to the planting device with members fixed to the planting device such as the hose guide frame (137), the holding band (138), and the support arm (140) in Patent Document 1, 1 and the like, such as the hose coupling body (141) and the left and right locking portions (142) in FIG.
JP 2000-152706 A (FIG. 20)

ところが、上記特許文献1のような構成であると、ホースは複数の箇所で固定部材により支持されるようになっており、ホースの配管経路を規制するホース支持部材を植付装置に多数設ける必要があり、植付装置の構造が複雑になってしまうという問題があった。   However, with the configuration as in Patent Document 1, the hose is supported by the fixing member at a plurality of locations, and it is necessary to provide a large number of hose support members for regulating the piping path of the hose in the planting device. There is a problem that the structure of the planting device becomes complicated.

(Constitution)
The first feature of the present invention is that a planting device is connected to the traveling machine body so as to be movable up and down, and a hopper for putting the agricultural powder particles into the traveling machine body, and a multi-row feeding for feeding the agricultural powder particles in the hopper. A planting device, a planting device, and a hose for connecting the feeding unit and the groove-growing device, including a seedling stage and a groove-growing device for forming a groove for supplying the agricultural granular material to the surface. In the riding type rice transplanter having
A support member that supports the hose is provided in a planting device, and the support member is configured to be urged in a lateral direction along the back surface of the seedling stage,
When the planting device is raised and the hose sag, the support member is configured to include a piping path changing mechanism that changes the piping path of the hose by displacing the hose in the lateral direction along the back surface of the seedling mount. It is.

(作用)
本発明の第1特徴によると、植付装置を上昇させて、ホースがたるむと、ホースを苗載台の裏面に沿った横方向に変位させて、ホースの配管経路を変更する配管経路変更機構を備えて構成してあるので、以下のような作用が生じる。
植付装置が非上昇位置にあれば、ホースはたるまないので、繰り出し部と作溝器とを連結するホースは通常の配管経路を維持しており、周辺の部材(例えば後輪)とは干渉しない。植付装置を上昇させたときは、繰り出し部と作溝器とが接近することでホースにたるみが生じる。たるんだホースが配管経路変更機構により苗載台の裏面に沿った横方向に変位することで、正面視或いは平面視で変位前の配管経路とは異なり、たるんだホースは重力により下方に垂れ下がった配管経路をとることはなく、周辺の部材(例えば後輪)と干
渉しないような配管経路に変更される。このように、ホースを固定支持するための部材を植付装置に多数設けなくても、配管経路変更機構を設けることによりホースと周辺の部材(例えば後輪)との干渉が防止でき、適切な配管経路を構造簡単に構成できる。
ホースを支持する支持部材を植付装置に備えて、支持部材が苗載台の裏面に沿った横方向に付勢されるように構成してあるので、植付装置が上昇しホースにたるみが生じると、ホースを支持している支持部材の支持位置が付勢により横方向に変位し、ホースの配管経路が変更される。また、植付装置が下降し、繰り出し部と作溝器との距離が長くなると、繰り出し部と作溝器とを連結するホースの張力は増大し、横方向に変位していた支持位置は、増大したホースの張力により、付勢に抗して変位前の位置に戻されるように操作され、ホースの配管経路が元の状態に戻る
このように、植付装置の昇降に応じて、ホースの支持位置の横方向への移動が付勢或いはホース自体の張力により行われるので、ホースのたるみに応じて支持位置を移動操作するための別の機構は必要なく、支持部材単体でホースのたるみに応じた配管経路変更を行うことができる。
(Function)
According to the first feature of the present invention, when the planting device is raised and the hose sag, the piping path changing mechanism for changing the hose piping path by displacing the hose laterally along the back surface of the seedling platform. Therefore, the following effects are produced.
If the planting device is in the non-lifted position, the hose will not sag, so the hose connecting the feeding section and the groover maintains a normal piping path and interferes with surrounding members (for example, rear wheels). do not do. When the planting device is raised, sagging occurs in the hose due to the close-up of the feeding portion and the groove generator. The sagging hose hangs down due to gravity, unlike the piping path before displacement in front view or plan view, as the sagging hose is displaced laterally along the back of the seedling platform by the piping path changing mechanism. The piping route is not taken, and the piping route is changed so as not to interfere with surrounding members (for example, rear wheels). Thus, without providing a large number of members for fixing and supporting the hose in the planting device, interference between the hose and surrounding members (for example, rear wheels) can be prevented by providing a piping path changing mechanism, Piping path can be constructed with simple structure.
Since the planting device is provided with a support member that supports the hose, and the support member is configured to be urged in the lateral direction along the back surface of the seedling table, the planting device is raised and sagging in the hose When this occurs, the support position of the support member supporting the hose is displaced laterally by the bias, and the piping path of the hose is changed. Also, when the planting device is lowered and the distance between the feeding part and the groove producing device becomes longer, the tension of the hose connecting the feeding part and the groove producing device increases, and the support position that has been displaced laterally is Due to the increased tension of the hose, it is operated so as to return to the position before the displacement against the bias, and the piping path of the hose returns to the original state .
Thus, as the planting device moves up and down, the hose support position is moved laterally by urging or tension of the hose itself, so that the support position is moved according to the slack of the hose. A separate mechanism is not required, and the piping route can be changed according to the slack of the hose with the support member alone.

(効果)
本発明の第1特徴によると、適切な配管経路を構造簡単に構成できるので、乗用型田植機の部品点数が抑制され、部材コスト低減が図られるとともに、外観が良くなるといった効果が期待できる。
また、ホースのたるみに応じて支持位置を移動操作するための別の機構は必要なく、支持部材単体でホースのたるみに応じた配管経路変更を行うことができるので、配管経路変更機構を簡単に構成することができ、乗用型田植機の部品点数が抑制され、部材コスト低減が図られるとともに、外観が良くなるという効果が期待できる。
(effect)
According to the first feature of the present invention, since an appropriate piping path can be configured with a simple structure, the number of parts of the riding rice transplanter can be suppressed, the member cost can be reduced, and the appearance can be improved.
Also, there is no need for a separate mechanism for moving the support position according to the slack of the hose, and it is possible to change the piping path according to the slack of the hose with a single support member. It can be configured, and the number of parts of the riding type rice transplanter can be suppressed, the cost of the member can be reduced, and the appearance can be improved.

図1には乗用型田植機の全体側面が、図2にはその全体平面が示されており、この乗用型田植機は、乗用型の走行機体1の後部に、油圧シリンダ2の作動で昇降揺動するリンク機構3を介して苗植付装置4を連結し、かつ、施肥装置5を搭載することによってミッドマウント施肥仕様に構成されている。   FIG. 1 shows an overall side view of the riding type rice transplanter, and FIG. 2 shows an overall plan view thereof. This riding type rice transplanter is moved up and down by the operation of a hydraulic cylinder 2 at the rear of the riding type traveling machine body 1. By connecting the seedling planting device 4 via the swinging link mechanism 3 and mounting the fertilizer application device 5, it is configured to have a mid-mount fertilization specification.

図1及び図2に示すように、走行機体1は、その前部に搭載されたエンジン6からの動力を、ベルト式伝動装置7及び静油圧式無段変速装置8を介してギヤ式伝動装置9に伝達し、そのギヤ式伝動装置9からの走行用動力を左右の前輪10及び後輪11に伝達する四
輪駆動形式に構成され、その後部側には、左右の前輪10を操向操作するステアリングホイール12や運転座席13などを備えた搭乗運転部14が形成されている。
As shown in FIGS. 1 and 2, the traveling machine body 1 transmits power from an engine 6 mounted on the front thereof via a belt-type transmission device 7 and a hydrostatic continuously variable transmission 8. 9 and is configured to be a four-wheel drive type that transmits the driving power from the gear type transmission device 9 to the left and right front wheels 10 and the rear wheels 11, and on the rear side, the left and right front wheels 10 are steered. A boarding operation unit 14 including a steering wheel 12 and a driver seat 13 is formed.

苗植付装置4は、機体の走行に伴って整地フロート15が苗植え付け箇所を前もって整地する一方で、ギヤ式伝動装置9からの作業用動力が動力分配機構16(図3及び図4参照)に伝達され、その動力分配機構16からの分配動力で、苗載台17が左右方向に一定ストロークで往復駆動されるとともに、左右方向に所定間隔を隔てて並設されたロータリ式の各植付機構18が、苗載台17の下端から苗を所定量ずつ取り出して圃場に植え付ける植え付け作動を行うように構成されている。   In the seedling planting device 4, the ground leveling float 15 levels the seedling planting site in advance as the aircraft travels, while the working power from the gear type transmission device 9 is the power distribution mechanism 16 (see FIGS. 3 and 4). The seedling stage 17 is reciprocated with a constant stroke in the left-right direction with the distributed power from the power distribution mechanism 16, and each of the rotary type plantings arranged side by side at a predetermined interval in the left-right direction. The mechanism 18 is configured to perform a planting operation in which a predetermined amount of seedlings are taken out from the lower end of the seedling mount 17 and planted in the field.

施肥装置5は、機体の走行に伴って各植え付け条に対応するように整地フロート15に装備された作溝器19が施肥溝を形成する一方で、各繰出し装置20がギヤ式伝動装置9からの作業用動力で肥料ホッパ21内の肥料を所定量ずつ繰り出し、送風装置22の作動で各繰出し装置20において繰り出された肥料を施肥ホース23を介して対応する作溝器19に向けて圧送することで、圃場における植え付け苗の横側方箇所に肥料を埋没させるように構成されている。以下に機体中央より左側の構成部品で説明するが、右側部分いついても同様に構成されている。   In the fertilizer application 5, the grooving device 19 provided in the leveling float 15 forms a fertilization groove so as to correspond to each planting line as the machine travels, while each feeding device 20 is connected to the gear transmission 9. The fertilizer in the fertilizer hopper 21 is fed out by a predetermined amount with the working power, and the fertilizer fed out in each feeding device 20 by the operation of the blower 22 is pumped toward the corresponding groove forming device 19 through the fertilizing hose 23. Thus, the fertilizer is configured to be buried in the lateral side portion of the planted seedling in the field. In the following description, the left side component from the center of the fuselage will be described, but the right side portion is configured in the same manner.

図3及び図4に示すように、施肥ホース23内での風圧が所定以上に強くなると開弁してエア抜き可能なリリーフ弁24が、苗載台17の裏面側における施肥ホース23の途中部位に設けてある。苗植付装置4の裏面側の下部で左右に亘って架設された植付部フレーム25の左右端部には、一対の苗載台サポート26が苗載台17の上方側に向かって延出するように設けられており、苗載台サポート26には、ブラケット27を介して植付部フレーム25と平行に取付ステー28が設けられている。リリーフ弁24には係止部24aが設けてあり、係止部24aにおいて取付ステー28がリリーフ弁24にボルト連結されている。   As shown in FIG. 3 and FIG. 4, a relief valve 24 that can be opened and vented when the wind pressure in the fertilizer hose 23 becomes stronger than a predetermined value is located in the middle of the fertilizer hose 23 on the back side of the seedling platform 17. Is provided. A pair of seedling support 26 extends toward the upper side of the seedling support 17 at the left and right ends of the planting part frame 25 erected across the left and right in the lower part on the back side of the seedling planting device 4. The seedling support 26 is provided with a mounting stay 28 in parallel with the planting part frame 25 via a bracket 27. The relief valve 24 is provided with a locking portion 24a, and the mounting stay 28 is bolted to the relief valve 24 at the locking portion 24a.

図6に示すように、リリーフ弁24は、施肥ホース23を外嵌接続する筒本体24bから、上斜め横に枝分かれした分岐路24cを突設するとともに、自重下降付勢されたキャップ24dを分岐路24cの先端に被せて構成してある。係止部24aは、筒本体24bに一体成形にされた互いに平行な対向面を有した一対のフランジ24eにより形成されている。両フランジ24eの間にホースガイド29(本発明の支持部材に相当)の根元側が位置しており、ホースガイド29とリリーフ弁24がボルト30により取付ステー28に共締め固定されている。   As shown in FIG. 6, the relief valve 24 projects from the cylinder body 24 b that externally connects the fertilizer hose 23, a branch path 24 c that branches obliquely upward and laterally, and branches a cap 24 d that is biased downward by its own weight. It is constructed so as to cover the end of the path 24c. The locking portion 24a is formed by a pair of flanges 24e that are formed integrally with the cylinder main body 24b and have opposing surfaces parallel to each other. The root side of the hose guide 29 (corresponding to the support member of the present invention) is located between the flanges 24e, and the hose guide 29 and the relief valve 24 are fastened to the mounting stay 28 together with bolts 30.

そして、ホースガイド29は施肥ホース23におけるリリーフ弁24よりも繰出し装置20側に向かって延出するように、取付ステー28に取付けてある。即ち、図6,図7及び図8に示すように、バネ線材を屈曲形成して長さの長いホースガイド29を構成してあり、その根元側を取付ステー28にボルト止めするとともに、施肥ホース23を係止して案内するループ部29aを先端に形成してある。ループ部29aは、平面視で機体外方側に開放口を有しており、略半円形の形状をしている。ホースガイド29は外力の作用しない自然状態においては、取付ステー28の取付面に対して斜め外側方向に向いている(図6参照)が、ループ部29aを施肥ホース23に係止させると、ホースガイド29が有する弾性力がループ部29aを機体横方向外側へ戻そうとする力と、施肥ホース23の張力がループ部29aを機体内側へ引く力とが釣り合う状態でループ部29aが位置決めされる。このように、施肥ホース23の張力とホースガイド29の弾性力とが平衡する状態で、施肥ホース23の配管経路が決定される。   The hose guide 29 is attached to the attachment stay 28 so as to extend toward the feeding device 20 side from the relief valve 24 in the fertilization hose 23. That is, as shown in FIGS. 6, 7 and 8, a long hose guide 29 is formed by bending a spring wire, and the base side is bolted to the mounting stay 28, and the fertilizer hose The loop part 29a which latches and guides 23 is formed in the front-end | tip. The loop portion 29a has an open port on the outer side of the machine body in a plan view, and has a substantially semicircular shape. In a natural state where no external force acts, the hose guide 29 faces obliquely outward with respect to the mounting surface of the mounting stay 28 (see FIG. 6). However, when the loop portion 29a is locked to the fertilizer hose 23, the hose guide 29 The loop part 29a is positioned in a state where the elastic force of the guide 29 balances the force of returning the loop part 29a outward in the lateral direction of the machine body and the force of the fertilizer hose 23 pulling the loop part 29a inward of the machine body. . In this way, the piping path of the fertilizer hose 23 is determined in a state where the tension of the fertilizer hose 23 and the elastic force of the hose guide 29 are balanced.

具体的には、苗植付装置4を下降位置にすると、繰出し装置20と作溝器19との距離が延びるので、両者を連結する施肥ホース23は平面視で直線状の配管経路をとり、ホー
スガイド29は弾性力を蓄えた状態で、施肥ホース23を係止保持することになる。苗植付装置4を上昇位置にすると、繰出し装置20と作溝器19との距離が縮むので、両者を連結する施肥ホース23に、たるみが生じる。このとき、弾性力を蓄えたホースガイド29が自然状態に戻ろうとするので、ホースガイド29のループ部29aの揺動によって、ループ部29aで係止されている施肥ホース23は平面視或いは正面視で迂回した配管経路をとる。したがって、苗植付装置4の上昇時に生じるたるみが配管経路の左右方向への変更により吸収されるので、周辺の部材との干渉を防止できる。
Specifically, when the seedling planting device 4 is in the lowered position, the distance between the feeding device 20 and the groove producing device 19 extends, so the fertilizer hose 23 that connects both takes a straight piping path in plan view, The hose guide 29 holds and holds the fertilizer hose 23 in a state where the elastic force is stored. When the seedling planting device 4 is set to the raised position, the distance between the feeding device 20 and the grooving device 19 is reduced, so that sagging occurs in the fertilizer hose 23 that connects the two. At this time, since the hose guide 29 storing the elastic force tends to return to a natural state, the fertilizer hose 23 locked by the loop portion 29a is swung in a plan view or a front view by the swinging of the loop portion 29a of the hose guide 29. Take a bypassed piping route. Therefore, the slack produced when the seedling planting device 4 is lifted is absorbed by the change of the piping path in the left-right direction, so that interference with surrounding members can be prevented.

このように、支持部材であるホースガイド29で施肥ホース23をガイドすることにより、苗植付装置4の昇降に伴なう施肥ホース23のたるみを吸収することができ、苗載台17の裏面に配備された植付装置のローリング対策用のバネ(図示せず)や後輪11との干渉を防止できる。また、他の機械装置類用のケーブル類のガイドとして使用可能であるとか、構成が簡潔であるので、外観が良くなるといった効果も期待できる。   Thus, by guiding the fertilization hose 23 with the hose guide 29 which is a support member, the slack of the fertilization hose 23 accompanying the raising and lowering of the seedling planting device 4 can be absorbed, and the back surface of the seedling mounting platform 17 It is possible to prevent interference with a spring (not shown) for preventing rolling of the planting device provided in the rear wheel 11 and the rear wheel 11. In addition, it can be used as a guide for cables for other mechanical devices, and since the configuration is simple, an effect of improving the appearance can be expected.

施肥ホース23を介して対応する作溝器19に向けて肥料を圧送するための風圧を生み出す送風装置22について説明する。図1,図2及び図9,図10に示すように、送風装置22は、ブロワ31及びこのブロワ31を駆動する電動モータ32が備えられている送風機33と、各繰出し装置20の下端部の前側に連結している送風ダクト34と、送風機33のブロワ31の吸気口31aから車体前方側に延出して延出端側がエンジン6及びエンジン排気マフラ36を有する原動部に開口している吸気ダクト35とを備えて構成してある。   The air blower 22 which produces the wind pressure for pumping the fertilizer toward the corresponding groove producing device 19 through the fertilizer hose 23 will be described. As shown in FIGS. 1, 2, 9, and 10, the blower 22 includes a blower 31 and a blower 33 provided with an electric motor 32 that drives the blower 31, and a lower end portion of each feeding device 20. A blower duct 34 connected to the front side, and an intake duct extending from the intake port 31a of the blower 31 of the blower 33 to the front side of the vehicle body and having an extended end side opened to a driving part having the engine 6 and the engine exhaust muffler 36. 35.

送風ダクト34は、複数の繰出し装置20のそれぞれの下端部の後面側に構成された肥料排出口39に対して、車体前後方向に一直線状に並んで連通するようにして設けてある風取入れ口40に対して接続している車体横向きの丸パイプ形状の分配ダクト部41と、この分配ダクト部41の車体横方向での中央部に位置する部分41aから車体下方向きで、かつ、やや前方向きに延出しているとともに中央部分41aとの単一部品になるようにこの中央部分41aに一体成形してある導入ダクト部42とによって構成してある。送風ダクト34の導入ダクト部42は、運転座席13の後方の車体左右方向での中央部に、車体フレームの後部の上方を覆っている車体カバー43を貫通している状態に配置してあり、導入ダクト部42の導入口42aは、車体カバー43の下方でブロワ31の吹出し口31bに対して接続してある。   The air duct 34 is provided so as to communicate with the fertilizer discharge port 39 formed on the rear side of the lower end of each of the plurality of feeding devices 20 in a straight line in the longitudinal direction of the vehicle body. The horizontal pipe-shaped distribution duct portion 41 that is connected to the vehicle body 40 and the portion 41a that is located at the center of the distribution duct portion 41 in the vehicle body lateral direction is directed downward from the vehicle body and slightly forward. And an introduction duct portion 42 formed integrally with the central portion 41a so as to be a single part with the central portion 41a. The introduction duct portion 42 of the air duct 34 is arranged in a state of passing through the vehicle body cover 43 covering the upper portion of the rear portion of the vehicle body frame at the center portion in the left-right direction of the vehicle body behind the driver seat 13. The introduction port 42 a of the introduction duct portion 42 is connected to the outlet 31 b of the blower 31 below the vehicle body cover 43.

つまり、送風装置22は、エンジン6を有する原動部の内部で加熱されて温度上昇した空気を、電動モータ32によって駆動されるブロワ31によって吸気ダクト35を介して吸引して温度の高い肥料搬送風を発生させ、この肥料搬送風を吹出し口31bから送風ダクト34の導入ダクト部42を通して分配ダクト部41に送り込み、この分配ダクト部41によって複数個の繰出し装置20に分配して各繰出し装置20の風取入れ口から肥料排出口39に供給する。   In other words, the air blower 22 sucks the air heated inside the prime mover having the engine 6 and having a temperature rise through the intake duct 35 by the blower 31 driven by the electric motor 32, so that the high-temperature fertilizer conveying wind is supplied. The fertilizer conveying wind is sent from the outlet 31b to the distribution duct portion 41 through the introduction duct portion 42 of the blower duct 34, and is distributed to the plurality of feeding devices 20 by the distribution duct portion 41. The fertilizer discharge port 39 is supplied from the wind intake port.

また、図10に示すように、ブロワ31の吸気口31aの下端の位置H1は、モータ32の外周下端の位置H2よりも、高さ方向で低くなるように構成されている。このように構成してあると、ブロワ31の内部に繰出し装置20側から水が浸入して、H1の高さに達した場合には、吸気ダクト35を介して機外へ水が排出される。したがって、ブロワ31内に大量に水が浸入しても、モータ32は浸水することがなく、モータ32の故障のおそれが少なくなる。   As shown in FIG. 10, the lower end position H <b> 1 of the air inlet 31 a of the blower 31 is configured to be lower in the height direction than the lower end position H <b> 2 of the outer periphery of the motor 32. With this configuration, when water enters the blower 31 from the feeding device 20 side and reaches the height of H1, the water is discharged to the outside through the intake duct 35. . Therefore, even if a large amount of water enters the blower 31, the motor 32 does not enter the water, and the possibility of failure of the motor 32 is reduced.
