Description

【0001】
【発明の属する技術分野】
本発明は、移植機等の走行作業機に装着される施肥装置の施肥ノズル操作構造に関する。
【0002】
【従来の技術】
従来、マット苗と植付爪で掻取って圃場に植付ける植付装置(作業機)を走行機体に装着し、作業機フレームに施肥装置の施肥ノズルを設けて苗の植付と施肥を同時に行なう移植機は既に知られている。
【0003】
一方、植付位置近傍に施肥を行う装置において、施肥ノズルをフロート側に設けた場合は、このノズルに対する圃場の抵抗によってフロートの姿勢が変わってしまい、フロートの均平性能や油圧感知に悪影響を与えるので、この影響を排除する意味で機体側にノズルを設ける構造を採用する必要がある。また、この構造の場合はフロートの上下調節によって植付深さを調節するに当たってノズルの深さ、即ち、施肥深さを調節する必要が発生する。
【0004】
また、施肥ノズルの回動支点を前側に設けることによって、吐出口を植付け位置に近づけて施肥の開始位置と終了位置を、植付開始位置と終了位置に近づけることができる上に施肥ノズルへの抵抗を少なくし、更にノズルへ稲わら等が引っかることを防止できるので、なるべく穏やかな傾斜で施肥ノズルを設けることが好ましく、このような技術上の問題点を解決するための施肥同時移植機は既に提案されている(例えば、特許文献1参照)。
【0005】
【特許文献1】
特開2000−209916号公報
【0006】
【発明が解決しようとする課題】
上記特許文献1に示されている水田作業機における施肥ノズルの調節機構は、作業機フレームに回動可能に設けた施肥ノズルを、リンク片及びロッドを介して後方側に向けて引き操作してプレート(ガイド部材)に位置決めすることにより回動させ、これによりフロートに対するノズル先端位置を調節することによって施肥深さ調節するようにしている。また施肥時に施肥ノズルが大きな土塊や石等の障害物に接当した場合に、その接当負荷を緩衝するためのスプリングは上記ロッドに嵌挿されている。
【0007】
従って、ロッド及びスプリング等が後方に長くなって施肥ノズル操作構造が大きくなるので、これらと植付爪との接当を回避するために植付部を後方に位置させる必要があり、そのため作業機フレームとして機能させている植付部伝動ケースが長大化する等の欠点がある。
【0008】
特に、特許文献1の図3及び図5に示されている植付伝動ケース19とその下方に設けたフロート10との間は図7に示すように複雑なリンク機構で連結され、しかもこのフロート10の前部に油圧式の感知機構を設けてフロート10の前部の上下動を感知して作業機2の田面追従を行うようにしている。従って、フロートの前部と植付部伝動ケースの下部との間に形成される狭い前部の空間に、植付深さ調節機構などを効果的に配置することが困難であった。
【0009】
また、ロッドに嵌挿したスプリングの荷重(接当負荷を緩衝する弾性力)を、ナットを調節して行なうスプリング荷重の設定操作は、作業勝手が後方になるため植付具に邪魔されて煩雑になる等の問題がある。
【0010】
本発明は前記従来技術の問題点である、植付伝動ケースとその下方で上下運動するフロートとの間の、しかもフロートの前側に形成される狭い空間に位置する部材を極力少なくして、施肥ノズルと施肥深さ調節機構と植付深さ調節の連動機構を、フロートの上部で、且つ伝動ケースの一側面に効果的に配置することによって施肥深さの調節を容易に、しかも正確に行うことができる装置を提供することを目的とするものである。
【0011】
【課題を解決するための手段】
上記目的を達成するための本発明に係る施肥同時移植機は、走行機体53の後部に、植付部2を備えた植付伝動ケース6とフロート3とを有する移植装置1をリンク機構54で連結し、前記走行機体側に対してフロート3を平行に上下させることによって植付深さ調節を行い、フロート前部の上下動の感知によって移植装置1を田面に追従して昇降させる施肥同時移植機において、前記植付伝動ケース6の前部に施肥ノズル回動軸16を設けると共に、この施肥ノズル回動軸16の後方に操作具回動軸10aを設け、操作具21と施肥ノズル4との間を緩衝部材22を介して連結し、操作具21とフロート3との間を連結部材9で連結したことを特徴としている。
【0012】
また、操作具21の回動支点をノズル回動支点の後方、且つ上方に配置し、緩衝部材22を縦方向に配置したことを特徴としている。
【0013】
【発明の実施の形態】
以下図面を参照しながら本発明の実施形態について説明する。
【0014】
図5は、6条植の乗用田植機(施肥作業機)の全体側面図、そして図6は乗用田植機の施肥装置の構成を示す平面図であり、先ず施肥同時移植機の全体構成を説明する。
【0015】
本発明に係る施肥同時移植機50の一例である乗用田植機は、前輪51と後輪52にて所定の地上高に支持された走行機体53と、この走行機体53の後部で油圧シリンダ及びリンク等からなる昇降機構54(リンク機構)によって昇降動作される植付装置1を設けている。
【0016】
この植付装置1は従来の装置と同様な構成によって、3体のフロート3を接地させた状態で、その両側に配置した植付部(ロータリ型植付爪)7cによって苗載台57上のマット苗を掻取って6条分の苗を田面に植付ける。
【0017】
そして、走行機体53の機体フレーム53aは前部にエンジン58を搭載し、後部にハンドル59、運転席ステップ60及び運転席シート61からなる操縦部62が配置されている。更にエンジン58の下方にはミッションケース63が配置されており、このミッションケース63から後方に向けて2本の角パイプからなるメインフレーム65を延設し、その外側にサブフレーム65aを延設し、これらは横枠によって前後の数カ所を連結して機体フレーム53aを剛体枠構造に構成している。
【0018】
また、運転席シート61を支持する運転席フレーム61aは側部フレームを前後に立設し、その上部を横枠で連結して内部を側条施肥用変速装置67と深層施肥用変速装置68等からなる施肥変速装置等の設置空間部となるように形成し、これらの変速装置によってそれぞれ対応する側条肥料繰出装置69と深層肥料繰出装置69aを伝動するようにしている。
【0019】
一方、走行機体53の前部にはエンジン58の両側に肥料タンク70を配置しており、このタンク70の上をオペレータが移動できるようにステップによって覆っている。
【0020】
上記肥料タンク70は供給管71を介して側条肥料繰出装置69と深層肥料繰り出装置69aに供給可能に連結している。上記肥料タンク70は比較的高い位置に配置しているので二つの肥料繰り出し装置69、69aに円滑に移送することができる。
【0021】
この施肥同時移植機50は、肥料タンク70内に収容されたペースト状の肥料を、側条用変速装置によって変速駆動される側条肥料繰出装置69と深層肥料繰出装置69aでそれぞれ施肥条別に後方に向けて繰出し、繰出された肥料を肥料送り管72及びインジケータ73を介して、フロート3の両側に設けた側条用ノズル4と深層用ノズル4aから地中に向けて施肥するようになっている。
【0022】
次に本発明に適用する施肥装置の施肥ノズルの操作構造について説明する。
【0023】
図1は、図5に記載された施肥同時移植機の走行作業機に装着される植付装置1を苗載台等を省略し、植付部2、フロート3及び施肥装置の側条用施肥ノズル4等の構成を示す側面図であり、また、図2は図1の植付部2を省略して示す平面図である。
【0024】
同図において5と6は植付装置1の作業機フレームを構成する横枠と植付部伝動ケースであり、横枠5は植付装置1の前部で機体中に横設され、植付部伝動ケース6は横枠5に所定の植付間隔を有し、後方に向けて平行して複数本を固定している。
【0025】
そして各植付部伝動ケース6は前部側に駆動軸7を挿通し、後部側に設けた植付部2の回転軸7aを一連に回転させるようにしている。植付部2は回転軸7aに設けた植付ケース7bの両端側に植付爪7c(植付具)を従来のものと同様な構成によって設けることにより苗載台上のマット苗を1株分ずつ掻取って圃場に植付けるようになっている。
【0026】
次に、フロート3について説明する。
【0027】
このフロート3は平面視でT字型に形成されており、後部の両側に近接した位置に前記植付部2を配置し、前後及び巾の中央部に取付座8を立設している。そしてこの取付座8の上下に設けた支軸9a,9bと、植付部伝動ケース6の前部側に設けた上下の支軸10a(操作具回動軸),10bは各植付部伝動ケース6にわたって積設されており、植付深さ調節レバー12の操作によって各フロート3を一体的に上下させるようになっている。また、支持杆11a、11b(リンク部材)と取付座8と深さ調節レバー12とで4つ棒平行リンクを形成するように連結している。
【0028】
この構成において支軸10bはその一側に植付深さ調節レバー12(操作具)を設けているとともに、他側に前記支持杆11bを一体的に設けている。この構成により植付深さ調節レバー12を前後方向に回動操作すると、フロート3は略平行状に上下され、このフロート3から下方への植付爪7cの植付軌跡の突出量を変えて植付深さ調節を行なうことができる。なお、図1は標準植付深さ状態を示し、図3は浅植付深さ状態を示す。また上記支軸10aと支軸9bには後述する施肥深さ操作レバー21の位置を設定するため板状のガイド部材9(連結部材)を遊嵌連結している。
【0029】
次に、施肥ノズル4の支持及び操作構造について説明する。
【0030】
この施肥ノズル4はパイプの基部側に図5及び図6に示した施肥タンク及び施肥ポンプから延設した施肥パイプ15(図2)と接続する支持管16(ノズル回動軸)を設け、中途部をフロート3に開口した開口部17から差し込み先端側をフロート3の裏側に沿わせて後方に延出し、そのノズル孔から例えばペースト状の肥料を植付爪7cによる植付条間の中程位置において地中に所定深さで施肥するようにしている。
【0031】
そして、上記支持管16の両側は植付部伝動ケース6の前部に固定された平面視コ字状のブラケット19に回動可能に支持し、支持管16の一側に取付けた、操作具回動軸10bをう回するようにへ字状に形成した作動片20を後方に向けて延設し、その後端を施肥深さ操作レバー21(操作具)と緩衝部材22を介して連結し、植付深さ調節レバー12を前後に回動させることにより施肥ノズル4を回動させるようにしている。
【0032】
即ち、施肥深さ操作レバー21は、その前端を施肥ノズル4の回動支点となる支持管16より後方で、しかも上方に別回動支点として位置する前記支軸10aに遊嵌支持している。そしてその中途部に設けた軸支部23と作動片20の後端に設けた連結ピン24を緩衝部材22(図4)によって連結している。
【0033】
そして施肥深さ操作レバー21はその後部に係止具25(図1、2)を突設し、この係止具25をガイド部材9(連結部材)に複数形成した凹突状の係止部26に選択的に係合させるようにしている。
【0034】
この構成により施肥深さ操作レバー21を図示例の最浅施肥深さ位置から下方の係止部26に係止させると、緩衝部材22及び作動片20を介して支持管16を支点として施肥ノズル4を下方に回動して施肥深さ調節を簡単に行なうことができ、ノズル孔から肥料を地中の所定深さ位置に施肥することができる。
【0035】
また、緩衝部材22は、図4に示すように連結ピン24に連結軸30の端部のリング材と嵌合枢支し、この連結軸30のネジ部側を支持部23にスライド可能に挿通させた状態で、連結ピン24と支持部23間に張りスプリング31を介装し、ネジ部に調節ナット32を螺挿している。
【0036】
この構成により植付装置1を上昇位置から「施肥植付同時作業」を行なう作業位置に下降させたとき、施肥ノズル4と地面との接地衝撃をスプリング31を縮めて緩衝する。そして施肥中に硬い土塊や石等の障害物と接当すると施肥ノズル4はスプリンク31に抗して上方に退動し、この障害物を乗り越えた後は元位置に復帰し施肥作業を円滑に行なう。
【0037】
また緩衝部材22は縦方向に設けて調節ナット32を上方側に位置させておくので、この調節ナット32によるスプリング31のスプリング荷重設定操作の作業勝手は上方側となり植付け具等に支障されることなく能率よく簡単に行なうことができる。
【0038】
以上のように構成された施肥ノズル操作構造を備えた施肥同時移植機は、施肥深さ操作レバー21を操作して施肥深さを調節して施肥ノズル4を圃場の諸条件に適応させた適正施肥深さ位置に設定した状態、及び植付深さ調節レバー12の適正植付深さ位置にフロート3を設定した状態で施肥植付同時作業を行なうと、植付爪7cはフロート3の両側で苗を適正深さに植付けるとともに、施肥ノズル4はその植付条間の適正位置に施肥する。
【0039】
また、フロート3の上下動とともにガイド部材9(連結部材)が回動し、このガイド部材9に係止された施肥深さ操作レバー21が上下回動し、緩衝部材22で作動片20を介してフロート3と一体的に施肥ノズル4を上下動させることができる。
【0040】
そして作業機フレーム6に施肥ノズル4と施肥深さ操作レバー21を別回動支点で回動可能に設けるとともに、施肥ノズル4を支持管16に緩衝部材22で連結したので、施肥深さ調節機構及び施肥深さ調節における連動機構をフロート3の中央上方の植付け伝動ケース6の側方に各部材を集中させて、フロート3の前部上方に配置される部材を極力少なくできる。
【0041】
また、施肥深さ操作レバー21を充分な長さに形成しているが、それ程後方側に延長することなく操作を行ない易くするとともに、緩衝部材22を施肥深さ操作レバー21と作動片20との間において縦方向に設置しており、この構成から従来の装置のように緩衝部材22を前後方向に長くしないから植付部2を施肥装置の施肥ノズル操作構造側に可及的に近接させて付部伝動ケース6の長さを長大化させることがない。
【0042】
また、施肥装置の施肥ノズル操作構造を植付部伝動ケース6の側方にコンパクトにまとめることができる。
【0043】
【発明の効果】
上記の説明から明らかなように、本発明にかかる施肥同時植付機は、走行機体53の後部に、植付部2を備えた植付伝動ケース6とフロート3とを有する移植装置1をリンク機構54で連結し、前記走行機体側に対してフロート3を平行に上下させることによって植付深さ調節を行い、フロート前部の上下動の感知によって移植装置1を田面に追従して昇降させる施肥同時移植機において、前記植付伝動ケース6の前部に施肥ノズル回動軸16を設けると共に、この施肥ノズル回動軸16の後方に操作具回動軸10aを設け、操作具21と施肥ノズル4との間を緩衝部材22を介して連結し、操作具21とフロート3との間を連結部材9で連結したことを特徴としている。
【0044】
従って施肥ノズルの深さ調節機構及び植付け深さ調節との連動機構を極力フロートの中央上部で、且つ植付け伝動ケースの一側方に形成されている比較的広い空間に極力集中配置することで、フロートの上下動や油圧感知機構の配置の妨げにならず、また、容易に着脱が可能で、施肥ノズルの操作を容易に行うことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fertilizer application nozzle operation structure of a fertilizer device mounted on a traveling work machine such as a transplanter.
[0002]
[Prior art]
Conventionally, a planting device (working machine) that scrapes with a mat seedling and planting nails and plant it in the field is mounted on the traveling machine, and a fertilizing nozzle of a fertilizer is installed on the working machine frame to plant and seed the seedling simultaneously. Performing transplanters are already known.
[0003]
On the other hand, in a device that performs fertilization near the planting position, when a fertilizer application nozzle is provided on the float side, the attitude of the float changes due to the resistance of the field to the nozzle, which adversely affects the float leveling performance and oil pressure sensing. Therefore, it is necessary to adopt a structure in which a nozzle is provided on the fuselage side to eliminate this effect. Further, in the case of this structure, it is necessary to adjust the depth of the nozzle, that is, the fertilization depth when adjusting the planting depth by adjusting the float vertically.
[0004]
In addition, by providing the rotation fulcrum of the fertilizer nozzle on the front side, the discharge port can be brought closer to the planting position, and the start and end positions of fertilizer can be closer to the planting start position and the end position, and the The fertilizer application nozzle is preferably provided with a gentle inclination as much as possible because it can reduce the resistance and prevent the rice straw and the like from being caught on the nozzle, and a simultaneous fertilizer application transplanter for solving such technical problems Has already been proposed (for example, see Patent Document 1).
[0005]
[Patent Document 1]
JP 2000-209916 A
[Problems to be solved by the invention]
The adjusting mechanism of the fertilizing nozzle in the paddy field working machine disclosed in Patent Document 1 described above pulls the fertilizing nozzle rotatably provided on the working machine frame toward the rear side via a link piece and a rod. The fertilizer is rotated by positioning it on a plate (guide member), and thereby the depth of fertilization is adjusted by adjusting the position of the nozzle tip with respect to the float. Further, when the fertilizing nozzle comes into contact with an obstacle such as a large earth mass or a stone during fertilization, a spring for buffering the contact load is fitted to the rod.
[0007]
Therefore, since the rod, the spring, and the like become longer and the fertilizing nozzle operating structure becomes larger, it is necessary to position the planting portion rearward to avoid contact with these and the planting claw. There are drawbacks such as the planting part transmission case functioning as a frame being lengthened.
[0008]
In particular, the planting transmission case 19 shown in FIGS. 3 and 5 of Patent Document 1 and the float 10 provided thereunder are connected by a complicated link mechanism as shown in FIG. A hydraulic sensing mechanism is provided at the front of the float 10 to sense the vertical movement of the front of the float 10 so that the work machine 2 follows the rice field. Therefore, it has been difficult to effectively arrange a planting depth adjustment mechanism or the like in a narrow front space formed between the front part of the float and the lower part of the planting part transmission case.
[0009]
Also, the spring load setting operation performed by adjusting the nut to adjust the load of the spring inserted into the rod (the elastic force for buffering the contact load) is complicated because the operation is rearward and is hindered by the planting tool. Problem.
[0010]
The present invention provides a fertilizer application method which minimizes the number of members located in a narrow space formed between a planting transmission case and a float that moves up and down below the planting transmission case and that is a front side of the float. The nozzle, fertilization depth adjustment mechanism, and interlocking mechanism of planting depth adjustment are effectively arranged on the upper part of the float and on one side of the transmission case to easily and accurately adjust the fertilization depth. It is an object of the present invention to provide a device capable of performing such operations.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the simultaneous fertilizer application transplanter according to the present invention uses the link mechanism 54 to connect the transplantation apparatus 1 having the planting transmission case 6 having the planting section 2 and the float 3 to the rear of the traveling machine body 53. Simultaneous fertilization fertilization in which the planting depth is adjusted by connecting and moving the float 3 up and down in parallel with the traveling body side, and the transplanting device 1 is moved up and down following the rice paddle by sensing the vertical movement of the float front. In the machine, a fertilizing nozzle rotation shaft 16 is provided at a front portion of the planting transmission case 6, and an operation tool rotation shaft 10 a is provided behind the fertilization nozzle rotation shaft 16 so that the operation tool 21, the fertilization nozzle 4, Are connected via a buffer member 22, and the operating tool 21 and the float 3 are connected by a connecting member 9.
[0012]
Further, the rotation fulcrum of the operating tool 21 is arranged behind and above the nozzle rotation fulcrum, and the buffer member 22 is arranged in the vertical direction.
[0013]

The float 3 is formed in a T-shape in plan view. The planting portion 2 is arranged at a position close to both sides of a rear portion, and a mounting seat 8 is erected at the center of the front, rear, and width. The support shafts 9a and 9b provided above and below the mounting seat 8 and the upper and lower support shafts 10a (operating tool rotation shafts) and 10b provided on the front side of the planting portion transmission case 6 are connected to the respective planting portion transmissions. The floats 3 are stacked over the case 6, and each float 3 is moved up and down integrally by operating the planting depth adjusting lever 12. Further, the supporting rods 11a and 11b (link members), the mounting seat 8 and the depth adjusting lever 12 are connected so as to form a four-bar parallel link.
[0028]
In this configuration, the support shaft 10b is provided with a planting depth adjusting lever 12 (operating tool) on one side, and the support rod 11b is integrally provided on the other side. When the planting depth adjusting lever 12 is rotated in the front-rear direction by this configuration, the float 3 is moved up and down in a substantially parallel shape, and the projecting amount of the planting claw 7c projected downward from the float 3 is changed. The planting depth can be adjusted. FIG. 1 shows a standard planting depth state, and FIG. 3 shows a shallow planting depth state. A plate-like guide member 9 (connection member) is loosely connected to the support shaft 10a and the support shaft 9b for setting the position of a fertilization depth operation lever 21 described later.
[0029]
Next, the support and operation structure of the fertilizer application nozzle 4 will be described.
[0030]
The fertilizing nozzle 4 is provided with a support pipe 16 (nozzle rotating shaft) connected to a fertilizing pipe 15 (FIG. 2) extending from the fertilizing tank and the fertilizing pump shown in FIGS. 5 and 6 at the base side of the pipe. The part is inserted from the opening 17 opened to the float 3 and the front end side extends rearward along the back side of the float 3, and for example, paste-like fertilizer is injected from the nozzle hole in the middle of the planting line by the planting claw 7 c. Fertilizer is applied at a predetermined depth in the ground at the location.
[0031]
An operating tool mounted on one side of the support tube 16 is rotatably supported on both sides of the support tube 16 by a bracket 19 having a U-shape in a plan view and fixed to a front portion of the planting portion transmission case 6. An operating piece 20 formed in a U-shape so as to rotate around the rotating shaft 10b is extended rearward, and its rear end is connected to a fertilization depth operating lever 21 (operating tool) via a buffer member 22. By turning the planting depth adjusting lever 12 back and forth, the fertilizing nozzle 4 is turned.
[0032]
That is, the fertilization depth operation lever 21 has its front end loosely supported by the support shaft 10a located behind and above the support pipe 16 serving as the rotation fulcrum of the fertilization nozzle 4 as another rotation fulcrum. . The shaft support 23 provided in the middle thereof and a connection pin 24 provided at the rear end of the operation piece 20 are connected by a buffer member 22 (FIG. 4).
[0033]
The fertilization depth operation lever 21 has a locking member 25 (FIGS. 1 and 2) protruding from the rear portion thereof, and a plurality of locking members 25 formed on the guide member 9 (connection member). 26 is selectively engaged.
[0034]
With this configuration, when the fertilization depth operation lever 21 is locked to the locking portion 26 below the shallow fertilization depth position in the illustrated example, the fertilization nozzle is supported by the support pipe 16 via the buffer member 22 and the operating piece 20 as a fulcrum. 4 can be turned downward to easily adjust the fertilization depth, and the fertilizer can be applied from the nozzle hole to a predetermined depth position in the ground.
[0035]
As shown in FIG. 4, the buffer member 22 is pivotally fitted to the connection pin 24 with the ring member at the end of the connection shaft 30, and the screw side of the connection shaft 30 is slidably inserted into the support portion 23. In this state, a tension spring 31 is interposed between the connecting pin 24 and the support portion 23, and an adjusting nut 32 is screwed into the screw portion.
[0036]
With this configuration, when the planting device 1 is lowered from the ascending position to the work position where the “simultaneous fertilization and planting work” is performed, the spring 31 contracts and cushions the ground contact impact between the fertilization nozzle 4 and the ground. And when it comes into contact with obstacles such as hard lumps and stones during fertilization, the fertilization nozzle 4 retreats upward against the sprinkles 31 and returns to its original position after overcoming this obstacle, facilitating fertilization work. Do.
[0037]
In addition, since the cushioning member 22 is provided in the vertical direction and the adjusting nut 32 is positioned on the upper side, the workability of the spring load setting operation of the spring 31 by the adjusting nut 32 is on the upper side, so that the planting tool and the like may be disturbed. Can be performed efficiently and easily.
[0038]
The fertilizer simultaneous transplanter having the fertilizer nozzle operating structure configured as described above operates the fertilizer depth operating lever 21 to adjust the fertilizer depth and adjusts the fertilizer nozzle 4 to various conditions in the field. When the fertilizer application is performed simultaneously with the fertilizer application position set at the fertilization depth position and the float 3 set at the appropriate planting depth position of the planting depth adjusting lever 12, the planting claws 7c are moved to both sides of the float 3. At the same time, the seedlings are planted to an appropriate depth, and the fertilizing nozzle 4 applies fertilizer to an appropriate position between the planting strips.
[0039]
In addition, the guide member 9 (connecting member) rotates with the up and down movement of the float 3, and the fertilization depth operation lever 21 locked by the guide member 9 rotates up and down. The fertilizer application nozzle 4 can be moved up and down integrally with the float 3.
[0040]
The fertilizer application nozzle 4 and the fertilizer application depth operating lever 21 are rotatably provided at a separate fulcrum on the work machine frame 6 and the fertilizer application nozzle 4 is connected to the support pipe 16 by the buffer member 22. In addition, the interlocking mechanism for adjusting the fertilization depth is such that each member is concentrated on the side of the planting transmission case 6 above the center of the float 3 and the members arranged above the front part of the float 3 can be reduced as much as possible.
[0041]
Further, although the fertilization depth operation lever 21 is formed to have a sufficient length, it is easy to perform the operation without extending so much rearward, and the buffering member 22 is connected to the fertilization depth operation lever 21 and the operating piece 20. In this configuration, the buffer member 22 is not lengthened in the front-rear direction as in the conventional device, so that the planting unit 2 is brought as close as possible to the fertilizing nozzle operation structure side of the fertilizing device. The length of the attachment transmission case 6 is not increased.
[0042]
Further, the structure for operating the fertilizer nozzle of the fertilizer applicator can be compactly arranged on the side of the planting part transmission case 6.
[0043]
【The invention's effect】
