When the term “right” or “left” is used, the right hand side is referred to as the right and the left hand side is referred to as the left when viewed from the operator standing at the front of the aircraft at the front of the aircraft.

苗移植機は走行装置1と操縦ハンドル2を備えた機体に昇降駆動するリンク機構3と連結して昇降動作する開閉可能なくちばし状の苗植付具4aを備えた苗植付装置4を設けた構成としている。
走行装置1は図示例では、エンジン5と該エンジン5の動力が伝達されて駆動回転する左右一対の後輪7,7と転動自在に支持した左右一対の前輪6,6とを備えたものとしている。
The seedling transplanter is provided with a seedling planting device 4 having a beak-shaped seedling planting tool 4a that can be opened and closed by connecting to a link mechanism 3 that is driven to move up and down to a machine body that includes a traveling device 1 and a steering handle 2. It has a configuration.
In the illustrated example, the traveling device 1 includes an engine 5, a pair of left and right rear wheels 7 that are driven and rotated by transmission of the power of the engine 5, and a pair of left and right front wheels 6 and 6 that are rotatably supported. It is said.

エンジン5の後部には、ミッションケース8を配置し、そのミッションケース8は、その左側部からエンジン5の左側方に延びるケース部分を有し、これがエンジン5の左側部と連結している。このケース部分にエンジン5の出力軸が入り込んでミッションケース8内の伝動機構に動力が伝達する構成となっている。ミッションケース8の左右両側部に伝動ケース9,9を回動自在に取り付け、この伝動ケース9,9の回動中心にミッションケース8から左右両外側方に延出させた車輪駆動軸9Aの先端が入り込んで伝動ケース9,9内の伝動機構に走行用の動力を伝達している。そして、走行用の動力は伝動ケース9,9内の伝動機構を介して、機体後方側に延びてその後端側側方に突出する後輪駆動軸10,10に伝動され、後輪7,7が駆動回転するようになっている。   A mission case 8 is disposed at the rear of the engine 5, and the mission case 8 has a case portion extending from the left side of the engine 5 to the left side of the engine 5, and this is connected to the left side of the engine 5. The output shaft of the engine 5 enters the case portion and the power is transmitted to the transmission mechanism in the transmission case 8. The transmission case 9, 9 is rotatably attached to the left and right side portions of the transmission case 8, and the tip of the wheel drive shaft 9A is extended from the transmission case 8 to the left and right outer sides at the rotation center of the transmission case 9, 9. Enters the transmission case 9, 9 to transmit power for traveling. Then, the driving power is transmitted to the rear wheel drive shafts 10 and 10 that extend to the rear side of the machine body and project to the rear end side through the transmission mechanism in the transmission cases 9 and 9. Is driven to rotate.

また、伝動ケース9,9のミッションケース8への取付部には、上方に延びるアーム9B,9Bを一体的に取り付けていて、該アーム9B,9Bに各々昇降用油圧シリンダ15が回動自在に連結している。昇降用油圧シリンダ15のピストンロッド15a(図2)の先端には機体に固着された横杆13が取り付けられている。
また、機体の水平制御をハンドル2に設けた手動レバー23により操作して機体の自動水平制御時に生じやすいハンチングを防止する。
Also, upwardly extending arms 9B and 9B are integrally attached to the attachment portions of the transmission cases 9 and 9 to the transmission case 8, and the lifting and lowering hydraulic cylinders 15 are rotatable on the arms 9B and 9B, respectively. It is connected. At the tip of the piston rod 15a (FIG. 2) of the lifting hydraulic cylinder 15, a horizontal rod 13 fixed to the machine body is attached.
Further, hunting that is likely to occur during automatic horizontal control of the aircraft is prevented by operating the horizontal control of the aircraft by a manual lever 23 provided on the handle 2.

また、昇降用油圧シリンダ15が作動してそのピストンロッド15aが収縮すると、これに伴い伝動ケース9,9が下方に回動して、機体が上昇する。
反対に、昇降用油圧シリンダ15のピストンロッド15aが突出すると、左右の前記アーム9B,9Bは前方に回動し、これに伴い伝動ケース9,9が上方に回動して、機体が下降する。この昇降用油圧シリンダ15は、機体に対する圃場面高さを検出するセンサS0の検出結果に基づいて機体を圃場面に対して設定高さになるよう作動するよう構成しており、また、操縦ハンドル2近傍に配置した操作具の人為操作によって機体を上昇或は下降させるよう作動する構成ともしている。
Further, when the elevating hydraulic cylinder 15 is actuated and the piston rod 15a is contracted, the transmission cases 9 and 9 are rotated downward and the airframe is raised.
On the other hand, when the piston rod 15a of the lifting hydraulic cylinder 15 protrudes, the left and right arms 9B, 9B rotate forward, and accordingly, the transmission cases 9, 9 rotate upward, and the fuselage descends. . The lifting / lowering hydraulic cylinder 15 is configured to actuate the aircraft to a set height with respect to the farm scene based on the detection result of the sensor S0 that detects the height of the farm scene relative to the aircraft. It is also configured to operate so as to raise or lower the fuselage by manipulating an operation tool disposed in the vicinity of 2.

さらに、前輪面がフラットになっている前輪6が溝の床面と接して溝の床面を平らにする。平らになった後の溝床面高さをセンサS0がセンシングするので、センサS0が適切に溝床面高さを検出するので、該検出結果に基づいて機体を溝の床面高さに対して設定高さになるよう作動させることができる。従って、苗の植付深さの制御にも用いることができる。なお、溝床面に植付溝を作るための突起S0aをセンサS0の底面の中央部に設けた。このため苗の植付位置での苗植付具4aの先端の溝床面に対する差し込みが容易になる。   Further, the front wheel 6 having a flat front wheel surface is in contact with the floor surface of the groove to flatten the floor surface of the groove. Since the sensor S0 senses the height of the groove floor after being flattened, the sensor S0 appropriately detects the height of the groove floor, so that the airframe is adjusted relative to the height of the groove floor based on the detection result. Can be operated to set height. Therefore, it can also be used to control the seedling planting depth. In addition, protrusion S0a for making a planting groove | channel on a groove floor surface was provided in the center part of the bottom face of sensor S0. For this reason, it is easy to insert the tip of the seedling planting tool 4a at the seedling planting position into the groove floor surface.

また、機体の左右水平制御ができる前記油圧シリンダ15が互いに異なる位置に伸縮作動すると、左右の伝動ケース9,9を互い違いに上下動させ機体を左右に傾斜させる。この左右水平制御用油圧シリンダ15は、手動レバー23の操作に基づいて機体を所望の左右傾斜姿勢になるように作動する構成にしている。
一対の前輪6,6は、車体に支持された左右一対の前輪支持フレーム16に取り付けられ前輪駆動軸17に回転自在に取り付けられている。
Further, when the hydraulic cylinder 15 capable of horizontal control of the aircraft is extended and retracted to different positions, the left and right transmission cases 9 and 9 are moved up and down alternately to incline the aircraft left and right. The left / right horizontal control hydraulic cylinder 15 is configured to operate so that the airframe is in a desired left / right inclined posture based on the operation of the manual lever 23.
The pair of front wheels 6, 6 are attached to a pair of left and right front wheel support frames 16 supported by the vehicle body and are rotatably attached to a front wheel drive shaft 17.

操縦ハンドル2は、ミッションケース8に前端部を固定した機体フレーム14の後端部に取り付けられている。機体フレーム14は、機体の左右中央から右側に偏った位置に配置されて後方に延び、また、前後中間部から斜め後上方に延びている。操縦ハンドル2は、機体フレーム14の後端部から左右に後方に延びてその各後端部を操縦ハンドル2のグリップ部2a,2aとしている。操縦ハンドル2の左右のグリップ部2a,2aは、作業者がそのグリップ部2a,2aを楽に手で握れるように適宜高さに設定する。なお、図例ではグリップ部2a,2aを左右に分かれた構成としているが、操縦ハンドル2の左右の後端部を互いに左右に連結してその連結部分をグリップ部2a,2aとしても良い。   The steering handle 2 is attached to the rear end portion of the body frame 14 whose front end portion is fixed to the mission case 8. The body frame 14 is disposed at a position deviated from the right and left center of the body to the right side and extends rearward, and extends obliquely rearward and upward from the front and rear intermediate portion. The steering handle 2 extends rearward from the rear end portion of the body frame 14 to the left and right, and the rear end portions thereof serve as grip portions 2 a and 2 a of the steering handle 2. The left and right grip portions 2a, 2a of the steering handle 2 are set to an appropriate height so that the operator can easily grip the grip portions 2a, 2a with hands. In the illustrated example, the grip portions 2a and 2a are divided into left and right. However, the left and right rear end portions of the steering handle 2 may be connected to each other left and right, and the connecting portions may be used as the grip portions 2a and 2a.

リンク機構3は、ミッションケース8内から苗植付具駆動用の動力を受けて伝動する伝動機構を内装する植付伝動ケース18に装着している。図例のように植付伝動ケース18は、その前部がミッションケース8の後部に連結し、そこから後斜め上方に延びる第一ケース部18aと、この第一ケース部18aの上部左側部に固定され、左側方に延びる第二ケース部18bと、その第二ケース部18bの左端部に固定され、後斜め下方に伸びる第三ケース部18cと、その第三ケース部18cの下端部外側部に固定され、左側方に伸びる第四ケース部18dと、その第四ケース部18dの左端部に固定され後方水平状に伸びる第五ケース部18eを有するものとしている。これら第一ケース部18a〜第五ケース部18e内にリンク機構3を昇降駆動するための動力を伝達する伝動機構を内装している。   The link mechanism 3 is attached to a planting transmission case 18 that includes a transmission mechanism that receives power for driving a seedling planting tool from the mission case 8 and transmits it. As shown in the figure, the planting transmission case 18 has a front portion connected to the rear portion of the mission case 8, a first case portion 18a extending rearward and obliquely upward therefrom, and an upper left portion of the first case portion 18a. A second case portion 18b that is fixed and extends to the left side, a third case portion 18c that is fixed to the left end portion of the second case portion 18b and that extends rearward and obliquely downward, and an outer lower end portion of the third case portion 18c. A fourth case portion 18d that is fixed to the left side and extends to the left side, and a fifth case portion 18e that is fixed to the left end portion of the fourth case portion 18d and extends horizontally rearward. The first case portion 18a to the fifth case portion 18e have a transmission mechanism that transmits power for driving the link mechanism 3 up and down.

なお、第一ケース部18a内に内装した伝動機構には、リンク機構3及び苗植付装置4をその昇降動最上位の位置で、又はその近傍位置で設定時間停止させる間欠駆動機構と、リンク機構3及び苗植付装置4の昇降動を停止させるクラッチ機構とを備えている。間欠駆動機構によって停止する時間は、該間欠駆動機構が備える変速機構によって調節され、この調節によって苗植付装置4による苗植付株間が変更調節されるようになっている。   The transmission mechanism built in the first case portion 18a includes an intermittent drive mechanism that stops the link mechanism 3 and the seedling planting device 4 at the uppermost position of the raising / lowering movement or at a position in the vicinity thereof, and a link. And a clutch mechanism for stopping the lifting and lowering of the mechanism 3 and the seedling planting device 4. The time for stopping by the intermittent drive mechanism is adjusted by a speed change mechanism provided in the intermittent drive mechanism, and the adjustment between the seedling planting stocks by the seedling planting device 4 is adjusted by this adjustment.

そして、リンク機構3は、苗植付装置4の前側に設けた左右方向の軸19の左右中間部に回動自在に連結する第一昇降アーム20と、苗植付装置4の後側に設けた左右方向の軸21の左側部に回動自在に連結する第二昇降アーム22とを備えている。
詳細は省略するが、第一昇降アーム20と第二昇降アーム22とが揺動しながら昇降動し、その結果、苗植付装置4の下端部が側面視で上下に長い略楕円形状の圃場に苗を植え付けるような軌跡で昇降動する。
The link mechanism 3 is provided on the rear side of the seedling planting device 4 and the first lifting arm 20 that is rotatably connected to the left and right intermediate portion of the left and right shaft 19 provided on the front side of the seedling planting device 4. And a second lifting arm 22 rotatably connected to the left side of the left and right shaft 21.
Although the details are omitted, the first lifting arm 20 and the second lifting arm 22 are moved up and down while swinging, and as a result, the lower end of the seedling planting device 4 has a substantially elliptical shape that is long in the vertical direction in a side view. It moves up and down with a trajectory like planting seedlings.

図4(a)の苗植付装置4の左右くちばし部4aL,4aRの背面図と図4(b)の左側面図と図4(c)の図4(b)のA−A線矢視断面図に示すように、苗植付装置4には、中央に設けた仕切板4aCを挟んで下方に向かって伸びる左側くちばし部4aLと右側くちばし部4aRを設けている。そして、苗供給装置40から落下してくる苗をそれぞれ仕切板4aCと左側くちばし部4aLの間及び仕切板4aCと右側くちばし部4aRの間に収納した苗植付装置4aはリンク機構3によって、側面視で上下に長い略楕円形状の軌跡Tに従って下降して圃場内に挿入され、左側くちばし部4aLと右側くちばし部4aRが機体左右方向に開放すると苗が圃場に植え付けられ、その後に苗植付装置4aが上昇する。   A rear view of the left and right beak parts 4aL and 4aR of the seedling planting device 4 in FIG. 4 (a), a left side view in FIG. 4 (b), and an AA line view in FIG. 4 (b) in FIG. 4 (c). As shown in the cross-sectional view, the seedling planting device 4 is provided with a left beak portion 4aL and a right beak portion 4aR that extend downward with a partition plate 4aC provided at the center therebetween. The seedling planting device 4a storing the seedlings falling from the seedling supply device 40 between the partition plate 4aC and the left beak portion 4aL and between the partition plate 4aC and the right beak portion 4aR is provided by the link mechanism 3 to the side surface. When the left and right beak parts 4aL and 4aR are opened in the horizontal direction of the machine body, the seedlings are planted in the field, and then the seedling planting device. 4a goes up.

苗植付装置4の下端部が左側方から見て反時計回りに略楕円形状の圃場に苗を植え付けるような軌跡Tで昇降回動する。従って、作業走行しながら苗植付装置4が上記回転方向で前記軌跡を描くように昇降回動すると、その軌跡の下端部で苗植付装置4の下端部が圃場の土壌中に苗を植付け、くちばし状の苗植付具4aを備えた苗植付装置4は、機体左右方向に開いて苗植付装置4内の苗を土壌に放出する。そのため、苗植付装置4で苗の左右方向の土が再度苗の周辺に流入し易くなり、より鎮圧輪38,38で覆土し易くなる。また、機体左右方向に開くことで、苗を溝部の土壌中に植え付けて挿して上昇するときに植え付けた苗に苗植付装置4が当たって苗の植付姿勢を乱すことを防止することができる。   The lower end portion of the seedling planting device 4 rotates up and down along a trajectory T in which a seedling is planted in a substantially elliptical field when viewed from the left side in a counterclockwise direction. Accordingly, when the seedling planting device 4 is moved up and down so as to draw the locus in the above rotation direction while traveling, the lower end of the seedling planting device 4 plantes the seedling in the soil of the field at the lower end of the locus. The seedling planting device 4 provided with the beak-shaped seedling planting tool 4a opens in the left-right direction of the machine body and releases the seedlings in the seedling planting device 4 to the soil. Therefore, the seedling planting device 4 makes it easier for the soil in the left-right direction of the seedling to flow again around the seedling and to cover the soil with the pressure-reducing wheels 38, 38 more easily. Moreover, it can prevent disturbing the planting posture of the seedling by the seedling planting device 4 hitting the seedling planted when the seedling is planted in the soil of the groove and inserted and raised by opening in the left-right direction of the aircraft. it can.

また、左側くちばし部4aLと右側くちばし部4aRの一部外周に泥寄せ部4bL、4bRを設け、該泥寄せ部4bL、4bRを多少柔軟性のある材料で構成すると、その外周部に設けた締め付け部材4cにより左右のくちばし部4aL,4aRへの取り付け上下方向に高さ位置が調節可能となり、さらに取外し可能にしている。   In addition, when the mud sucking portions 4bL and 4bR are provided on the outer periphery of the left beak portion 4aL and the right beak portion 4aR, and the mud sucking portions 4bL and 4bR are made of a slightly flexible material, the tightening provided on the outer peripheral portion thereof. The height position can be adjusted in the vertical direction of attachment to the left and right beak parts 4aL and 4aR by the member 4c, and further, it can be removed.

泥寄せ部4bL、4bRの高さ位置の調節は植え付ける苗丈(首元の長さ)に応じて行い、また泥寄せ部4bL、4bRの取り付けと取り外しの切替は、通常、植付時には取り外し、溝切り時には取り付けるためである。   Adjustment of the height position of the mud gathering parts 4bL, 4bR is performed according to the seedling height (the length of the neck) to be planted, and the switching of the attachment and removal of the mud gathering parts 4bL, 4bR is usually removed at the time of planting, This is for mounting at the time of grooving.

また、左右のくちばし部4aL,4aRに取り付ける泥寄せ部4bL、4bRの形状を変えることで、それぞれの形成される溝の形状を変えることができる。このように泥寄せ部4bL、4bRの形状を変えることで、溝の幅や深さを変えることができる。また、泥寄せ部4bL、4bRの前後方向の幅を植え付ける苗の隣接間隔(株間)より長くなる構成にすると、土壌に溝が形成されていない部分が無くなるので好都合である。   Moreover, the shape of each formed groove | channel can be changed by changing the shape of the mud gathering parts 4bL and 4bR attached to the right and left beak parts 4aL and 4aR. Thus, the width and depth of the groove can be changed by changing the shape of the mud collecting portions 4bL and 4bR. Moreover, when the width | variety of the front-back direction of mud gathering part 4bL, 4bR becomes longer than the adjacent space | interval (between strains) of the seedling to plant, since the part in which the groove | channel is not formed in soil is lost, it is convenient.

また、図4(b)と図4(c)に示すように泥寄せ部部4bL、4bRは、側面視において左右のくちばし部4aL,4aRより既に植え付けた苗から離れた位置で作溝することになるように前方側にずらしているので既に植え付けた苗を乱すことがない。   Also, as shown in FIGS. 4 (b) and 4 (c), the mud gathering portions 4bL, 4bR are grooved at positions farther from the seedlings already planted than the left and right beak portions 4aL, 4aR in a side view. Because it is shifted to the front side so as to become, will not disturb the already planted seedlings.

鎮圧輪38は支持部材34の先端に回動軸38aを持ち、該支持部材34の他端がフレーム33(第一フレーム33a,第二フレーム33b)に支持され、該第二フレーム33bの前端部は後輪駆動軸10に揺動自在に支持され、その後端部は機体フレーム14の操縦ハンドル2との接続部付近から垂下したスプリング35付きの第一フレーム33aと回動自在に接続している。また、第二フレーム33bの鎮圧輪38の支持部の近傍に作溝体36が支持ロッド37を介して支持されている。   The pressure reducing wheel 38 has a rotation shaft 38a at the tip of the support member 34, the other end of the support member 34 is supported by the frame 33 (first frame 33a, second frame 33b), and the front end portion of the second frame 33b. Is supported by the rear wheel drive shaft 10 in a swingable manner, and its rear end portion is rotatably connected to a first frame 33a with a spring 35 suspended from the vicinity of the connection portion with the steering handle 2 of the body frame 14. . Further, the groove forming body 36 is supported via a support rod 37 in the vicinity of the support portion of the pressure-reducing wheel 38 of the second frame 33b.

スプリング35で鎮圧輪38と作溝体36はフレーム33等を介して常に土壌面を押圧しているので、それぞれ土壌面に対して鎮圧効果と作溝効果が得られる。また、作溝体36は支持ロッドのフレーム33の取り付け位置を変更可能になっているので、作溝体36の圃場面からの高さを変えることができ、作物に応じて作溝深さを変更調節できる。   Since the pressure reducing wheel 38 and the groove forming body 36 always press the soil surface via the frame 33 and the like by the spring 35, a pressure reducing effect and a groove forming effect are obtained on the soil surface, respectively. Further, since the groove forming body 36 can change the mounting position of the frame 33 of the support rod, the height of the groove forming body 36 from the field can be changed, and the groove forming depth can be changed according to the crop. Can change and adjust.

図3(a)に苗移植機の鎮圧輪38と作溝体36の設置部分の背面図を、図3(b)に作溝体36の平面図に示す。
図3(a)に示すように鎮圧作業時には、鎮圧輪38は機体に支柱37で支持された作溝体36の圃場への侵入する側壁の傾斜角度の延長線上に同様の傾斜角度で作溝体が配置され、作溝体36の側方で土壌の溝の側方の土壌面に接地しているので、土壌面の溝後の鎮圧が効果的に行える。
FIG. 3A shows a rear view of the installation part of the pressure-reducing wheel 38 and the groove body 36 of the seedling transplanter, and FIG. 3B shows a plan view of the groove body 36.
As shown in FIG. 3 (a), during the pressure-reducing operation, the pressure-reducing wheel 38 is formed at a similar inclination angle on the extension line of the inclination angle of the side wall where the groove formation body 36 supported by the support body 37 by the support 37 enters the field. Since the body is arranged and is in contact with the soil surface on the side of the soil groove on the side of the groove body 36, the soil surface can be effectively suppressed after the groove.

また、図1に示すスプリング35付きの第一フレーム33aの機体フレーム14側の接続部も上下に揺動自在である。
従って、支持部材34が矢印A方向に揺動することで第一フレーム33aが収縮し、同時に鎮圧輪38と作溝体36が上昇する。最上昇位置に上げた鎮圧輪38と作溝体36は第一フレーム33aによりロック可能である。
Further, the connecting portion on the side of the body frame 14 of the first frame 33a with the spring 35 shown in FIG.
Therefore, when the support member 34 swings in the direction of arrow A, the first frame 33a contracts, and at the same time, the pressure reducing wheel 38 and the groove forming body 36 rise. The pressure-reducing wheel 38 and the grooved body 36 raised to the highest position can be locked by the first frame 33a.

なお、本実施例の苗植付機では苗植付具4aより機体後方に作溝体36が配置されているので、作溝体36による作溝は苗を植え付けないときに行う。また、図1で作溝体36の対地高さを高くするために作溝体36を上昇させたときには点線で示すように天地逆にに付け替える。   In the seedling planting machine of the present embodiment, the groove forming body 36 is arranged behind the seedling planting tool 4a, so that the groove formation by the groove forming body 36 is performed when a seedling is not planted. In addition, when the groove forming body 36 is raised in order to increase the ground height of the groove forming body 36 in FIG. 1, it is changed to the upside down as shown by the dotted line.

また図5(a)には作溝体36’と鎮圧輪38’の機体への取り付け構造の他の実施例の要部側面図を示し、図5(b)には図5(a)の作溝体36と鎮圧輪38’の接続構造を示す平面図であり、図5(c)は別の実施例の作溝体36”と鎮圧輪38”の接続関係を示す平面図である。   FIG. 5 (a) shows a side view of an essential part of another embodiment of the structure for attaching the groove forming body 36 ′ and the pressure reducing wheel 38 ′ to the airframe, and FIG. 5 (b) shows a side view of FIG. 5 (a). FIG. 5C is a plan view showing a connection structure between the groove forming body 36 ″ and the pressure reducing wheel 38 ″ according to another embodiment.

図5(a)と図5(b)に示す構成は、作溝体36に鎮圧輪38’を設け、土壌面をセンシングしながら溝切りを行うことができる。機体フレーム14に支持された支持フレーム50に上下方向に長いロッド33’を設け、該ロッド33’に接地輪38’が支持されている。該ロッド33’が遊嵌した支持フレーム55と一体の筒部55aに上端を支持されたスプリング35’がロッド33’を貫通して設けられ、該ロッド33’の下端に接地輪38’が支持されている。そのため接地輪38’が土壌面に凹凸に対応して上下してもスプリング33’でその上下動を吸収し、作溝体36’は接地輪38’に連動しながら土壌が凹凸状態であっても、確実に接地して溝を形成する。   The configuration shown in FIGS. 5A and 5B can provide a pressure-reducing wheel 38 ′ in the groove producing body 36 and can perform grooving while sensing the soil surface. The support frame 50 supported by the machine body frame 14 is provided with a rod 33 ′ that is long in the vertical direction, and a ground ring 38 ′ is supported by the rod 33 ′. A spring 35 ′ having an upper end supported by a cylindrical portion 55 a integrated with the support frame 55 in which the rod 33 ′ is loosely fitted is provided through the rod 33 ′, and a ground ring 38 ′ is supported at the lower end of the rod 33 ′. Has been. Therefore, even if the ground ring 38 'moves up and down corresponding to the unevenness on the soil surface, the vertical movement is absorbed by the spring 33', and the groove forming body 36 'is interlocked with the ground ring 38' and the soil is uneven. Also, the ground is surely grounded to form a groove.

また、図5(b)と図5(c)の平面図に示すように接地輪38’、38”の回転軸に作溝体36’、36”の支持ロッド33’、33”を取り付け、該ロッド33’、33”に作溝体36’、36”を高さ位置調節可能に取り付けているので、苗丈に応じて作溝体36’、36”の高さが調節可能となるので、溝深さの調節ができる。   Further, as shown in the plan views of FIGS. 5B and 5C, the support rods 33 ′ and 33 ″ of the groove forming bodies 36 ′ and 36 ″ are attached to the rotating shafts of the ground rings 38 ′ and 38 ″, Since the groove forming bodies 36 ', 36 "are attached to the rods 33', 33" so that the height position can be adjusted, the height of the groove forming bodies 36 ', 36 "can be adjusted according to the seedling height. Can adjust the groove depth.

図5(b)に示す構成では2つの接地輪38’に共通する回転軸38a’の中央部に作溝体36’を取り付けているので2輪の接地輪38’で土壌への沈み込みを防ぐことができる。また、図5(c)に示す構成では1つの幅広の接地輪38”の後方に作溝体36’を取り付けているので接地輪38”が一つですみコストダウン効果がある。   In the configuration shown in FIG. 5B, since the groove forming body 36 ′ is attached to the central portion of the rotation shaft 38a ′ common to the two grounding wheels 38 ′, the two grounding wheels 38 ′ can sink into the soil. Can be prevented. Further, in the configuration shown in FIG. 5 (c), since the groove forming body 36 'is attached to the rear side of one wide grounding ring 38 ", only one grounding ring 38" is required, and the cost can be reduced.

次に苗供給装置40関係の説明をする。
スプロケット51,51の一方の回転軸51aと第一ケース部18aとを伝動軸53を介して連結することでエンジン5からの動力を伝動して左右のスプロケット51,51を回転駆動させて苗供給カップ41を周回移動させる構成としている。
Next, the seedling supply device 40 will be described.
By connecting one rotating shaft 51a of the sprocket 51, 51 and the first case portion 18a via the transmission shaft 53, the power from the engine 5 is transmitted to rotate the left and right sprockets 51, 51 to supply seedlings. The cup 41 is configured to move around.

苗供給装置40の上方には、多数の苗供給カップ41が等間隔で連結され、苗供給カップ41の周回移動軌跡に沿う移動を案内するガイド体42,42を苗供給カップ41…の周回移動軌跡の内側と外側とにそれぞれ設けている。これにより、苗供給カップ41…の周回移動が適確且つ円滑に行われる。   A large number of seedling supply cups 41 are connected at equal intervals above the seedling supply device 40, and guide bodies 42, 42 that guide the movement of the seedling supply cup 41 along the circular movement trajectory are moved around the seedling supply cups 41. Provided inside and outside the trajectory, respectively. Thereby, the revolving movement of the seedling supply cups 41 is performed accurately and smoothly.

そして苗植付装置4は左右一対の前輪6,6の接地箇所より機体左右方向内側、すなわち、前輪6,6で走行していない土壌の部分に苗を植え付ける。
このような構成にすることで、一対の前輪6,6で踏み固められていない箇所に苗を植え付けることができる。
Then, the seedling planting device 4 plants seedlings on the inner side in the left-right direction of the machine body, that is, the portion of the soil that is not traveling on the front wheels 6, 6 from the ground contact point of the pair of left and right front wheels 6, 6.
By adopting such a configuration, seedlings can be planted in a place where the pair of front wheels 6 and 6 are not stepped on.

また、肥料、薬剤、土及び水などの副資材を貯留した副資材タンク44が植付伝動ケース18上に取り付けられており、該副資材タンク44から苗植付体4a内に所定量の副資材が繰り出し部44aにより供給される。   Further, a secondary material tank 44 storing secondary materials such as fertilizer, chemicals, soil and water is attached on the planting transmission case 18, and a predetermined amount of secondary material tank 44 is transferred from the secondary material tank 44 into the seedling planting body 4a. The material is supplied by the feeding unit 44a.

図6(a)に苗供給装置40と苗植付装置4との背面図に示すように苗供給カップ41から苗植付装置4の上端部にあるガイドパイプ4a1への苗引き継ぎの確実性向上のため、苗供給装置40に苗供給カップ41の苗外れ防止材43を設けた。該苗外れ防止材43として塩化ビニール樹脂などの弾性材を用いると、ガイドパイプ4a1と干渉しても変形しない。、また図6(b)に図6(a)の矢印A方向からの矢視図に示すように苗外れ防止材43はガイドパイプ4a1より外側に有り、ガイドパイプ4a1の切欠き部4a1a(苗植付装置4が上昇時に苗外れ防止材43と干渉しないようにするための空間部)より大きな面積を有する構成とする。   As shown in the rear view of the seedling supply device 40 and the seedling planting device 4 in FIG. 6A, the reliability improvement of the seedling transfer from the seedling supply cup 41 to the guide pipe 4a1 at the upper end of the seedling planting device 4 is improved. Therefore, a seedling removal prevention material 43 for the seedling supply cup 41 is provided in the seedling supply device 40. When an elastic material such as vinyl chloride resin is used as the seedling removal prevention material 43, it does not deform even if it interferes with the guide pipe 4a1. In addition, as shown in the arrow A direction of FIG. 6A from the direction of arrow A in FIG. 6B, the seedling removal prevention material 43 is located outside the guide pipe 4a1, and the notch 4a1a (the seedling) of the guide pipe 4a1 is provided. It is set as the structure which has a larger area than the space part for the planting apparatus 4 not to interfere with the seedling removal prevention material 43 at the time of raising.

また図6(c)に図6(a)の変形例の一部背面図を示すように苗外れ防止材43をガイドパイプ4a1の内側に収まる形状とすることもできる。
図7に苗供給装置40の平面図と図8(a)に苗供給装置40の苗供給カップ41部分の側面図と図8(b)に図8(a)のA−A線断面矢視図に示すように、苗供給装置40は、上下に開口する苗供給カップ41…と該苗供給カップ41…の下側の開口部…を開閉する底蓋41a…とを有し互いにループ状に連結する複数の苗供給カップ41…と、該苗供給カップ41…を前記苗植付装置4…の上方近傍を通過する状態で機体平面視前後に長い長円形状のループ状の軌跡で周回動させる移動機構(図示せず)と、前記苗供給カップ41…の底蓋41a…を苗植付装置4…の上方位置で開放する開放プレート57を設けた構成である。また移動機構の周回動軌跡のほぼ中央部に沿った形状で、一部前記底蓋41aの開放領域となる部分を除いてループ状のアーム58が設けられ、該アーム58が底蓋41aを開放しないように常時底蓋41aを下側から支持している。
Further, as shown in FIG. 6C, a partial rear view of the modified example of FIG. 6A, the seedling removal prevention material 43 can be shaped to fit inside the guide pipe 4a1.
7 is a plan view of the seedling supply device 40, FIG. 8A is a side view of the seedling supply cup 41 portion of the seedling supply device 40, and FIG. 8B is a cross-sectional view taken along line AA in FIG. As shown in the figure, the seedling supply device 40 has a seedling supply cup 41 that opens up and down, and a bottom lid 41a that opens and closes a lower opening of the seedling supply cup 41 and so on. A plurality of seedling supply cups 41 to be connected, and the seedling supply cups 41 are rotated around a long oval loop trajectory before and after the plane of the machine body in a state of passing above the seedling planting device 4. And a release plate 57 that opens the bottom lids 41a of the seedling supply cups 41 at a position above the seedling planting device 4. Further, a loop-shaped arm 58 is provided except for a portion that becomes an open area of the bottom cover 41a, and has a shape along the substantially central part of the circumferential rotation locus of the moving mechanism, and the arm 58 opens the bottom cover 41a. The bottom cover 41a is always supported from the lower side so as not to occur.

苗供給装置40は、前記苗供給カップ41…の外周に円筒外周部を形成し、該円筒外周部に外側から回動自在に係合する係合部(丸孔)を有して二つの苗供給カップ41,41を連結する連結体49を複数設け、該連結体49…の係合部を苗供給カップ41…の円筒外周部に回動自在に係合し該円筒外周部を回動軸として隣の苗供給カップ41…が回動自在に連結する状態として複数の苗供給カップ41…を互いに連結した構成としている。即ち、苗供給カップ41…と連結体49…とで無端チェーンのように連結した構成である。これにより、苗供給カップ41…は、直線的に移動する部分でも円弧状に移動する部分でも隣接する苗供給カップ41…との間隔が変わらないので、苗供給カップ41から苗植付装置4に苗を供給する個所で苗供給カップ41が苗植付装置4に対して位置ズレが生じにくくなり苗供給が適正に行われて、この苗移植機は適確な苗の移植ができる。   The seedling supply device 40 forms a cylindrical outer peripheral portion on the outer periphery of the seedling supply cup 41... And has an engagement portion (round hole) that engages the cylindrical outer peripheral portion so as to be rotatable from the outside. A plurality of connecting bodies 49 for connecting the supply cups 41, 41 are provided, the engaging portions of the connecting bodies 49 are rotatably engaged with the cylindrical outer peripheral portion of the seedling supply cups 41, and the cylindrical outer peripheral portion is rotated. As a state where the adjacent seedling supply cups 41 are rotatably connected, a plurality of seedling supply cups 41 are connected to each other. That is, the seedling supply cups 41 and the connecting bodies 49 are connected like an endless chain. Thereby, since the space | interval with the seedling supply cup 41 ... which the seedling supply cup 41 ... linearly moves or the part which moves circularly does not change, the seedling supply cup 41 is transferred to the seedling planting device 4. The seedling supply cup 41 is less likely to be misaligned with respect to the seedling planting device 4 at the location where the seedling is supplied, and the seedling transplanting machine can appropriately transplant the seedling.

上記苗供給装置40の苗供給カップ41の底蓋41aは該底蓋41aの下側に苗供給カップ41の移動する長い長円形状のループ状の軌跡に沿った形状のアーム58が配置されていて底蓋41aは開かないが、苗供給カップ41内の苗を苗植付装置4に落下させる領域ではアーム58がないので底蓋41aが開くようになっている。しかも、前記苗を苗植付装置4に苗を落下させる領域の微調整を開放プレート57で行うことができる。すなわち、開放プレート57のロッド57aに底蓋41aの突起部41a1が接当している状態では底蓋41aは開かないが、開放プレート57をスライド調整して、開放プレート57の閉じ用のロッド57aに底蓋41aの突起部41a1が接当しないようにすることで底蓋41aが開く構造である。   The bottom lid 41a of the seedling supply cup 41 of the seedling supply device 40 is provided with an arm 58 having a shape along a long oval loop trajectory in which the seedling supply cup 41 moves under the bottom lid 41a. Although the bottom lid 41a is not opened, the bottom lid 41a is opened because there is no arm 58 in the region where the seedling in the seedling supply cup 41 is dropped onto the seedling planting device 4. Moreover, fine adjustment of the area where the seedling is dropped onto the seedling planting device 4 can be performed with the open plate 57. That is, the bottom lid 41a does not open when the projection 57a1 of the bottom lid 41a is in contact with the rod 57a of the release plate 57, but the release plate 57 is slid to adjust the release rod 57 to close the release plate 57a. The bottom lid 41a is opened by preventing the projection 41a1 of the bottom lid 41a from coming into contact with the bottom lid 41a.

すなわち、底蓋41aの突起部41a1がアーム58と開放プレート57ののロッド57aから外れるとヒンジ41bを中心に底蓋41aが下方に開き、カップ41内の苗が苗植付装置4に落下する。次いで、その苗供給カップ41が移動してループ状アーム58に当たると再び底蓋41aが閉じる。   That is, when the protrusion 41a1 of the bottom lid 41a is disengaged from the arm 58 and the rod 57a of the opening plate 57, the bottom lid 41a opens downward around the hinge 41b, and the seedling in the cup 41 falls to the seedling planting device 4. . Next, when the seedling supply cup 41 moves and hits the loop arm 58, the bottom cover 41a is closed again.

しかし、底蓋41aが開いた後に、該蓋41aがアーム58に当たる前に隣接する底蓋41aの上側に入って、当該底蓋41aを挟んで隣接の底蓋41aを閉じることがある。そこで底蓋41aのヒンジ41bの端部に底蓋41aの平面に対して直交する方向に隣接する苗供給カップ41の突起片41cに接触する位置に面ファスナーなどを貼り付けた接触片41b1を一体的に取り付けておき、一旦、開いた底蓋41aが不用意に回動しないように、面ファスナーなどを貼り付けた接触片41b1を隣接する苗供給カップ41の突起片41a1に密着させて底蓋41aを、その開いた位置に保持させる。   However, after the bottom lid 41a is opened, the lid 41a may enter the upper side of the adjacent bottom lid 41a before hitting the arm 58, and the adjacent bottom lid 41a may be closed with the bottom lid 41a interposed therebetween. Therefore, a contact piece 41b1 having a surface fastener or the like attached to the end of the hinge 41b of the bottom cover 41a at a position in contact with the protruding piece 41c of the seedling supply cup 41 adjacent in the direction orthogonal to the plane of the bottom cover 41a is integrated. In order to prevent the opened bottom cover 41a from rotating carelessly, the contact piece 41b1 attached with a hook-and-loop fastener or the like is brought into close contact with the protruding piece 41a1 of the adjacent seedling supply cup 41 so that the bottom cover 41a is held in its open position.

また、図7に示すように前記底蓋41aの開放プレート57に設けた底蓋閉じ用のロッド57a、57aを一体化しておき、しかもこの開放プレート57をスライド可能にしておくと、底蓋41aの開放位置を調整可能となり、当該底蓋41aを挟んで隣接の底蓋41aが閉じるのを防ぐことができる。   As shown in FIG. 7, when the bottom cover closing rods 57a and 57a provided on the open plate 57 of the bottom cover 41a are integrated and the open plate 57 is slidable, the bottom cover 41a Can be adjusted, and the adjacent bottom lid 41a can be prevented from closing across the bottom lid 41a.

チェン式の苗供給カップ41と同軸上に該カップ41を移動されるためにスプロケット51,51(図2)間に張った駆動チェン(図示していない)を設けているが、チェン式の苗供給カップ41の軸間よりも駆動チェンの軸間の方が長くなるような構成にするとチェン式の苗供給カップ41にたるみが出ない。したがってカップ41が傾くおそれもなくなる。このとき駆動チェンにできる弛みはチェンを張る適宜のテンションを設けて吸収することができる。さらに底蓋41aの突起部41a1に接当させる開放プレート57の形状を根元は幅広く、先端の底蓋41aの突起部41a1が当接する部分を幅狭くすると、底蓋41aが開放してはいけない位置で、開放プレート57の幅広部分が底蓋41aに接当せず、底蓋41aが開くおそれが無くなる。   In order to move the cup 41 coaxially with the chain-type seedling supply cup 41, a drive chain (not shown) stretched between the sprockets 51, 51 (FIG. 2) is provided. If the configuration is such that the axis of the drive chain is longer than the axis of the supply cup 41, the chain-type seedling supply cup 41 does not sag. Therefore, there is no possibility that the cup 41 tilts. At this time, slack that can be generated in the drive chain can be absorbed by providing an appropriate tension for tensioning the chain. Further, when the shape of the opening plate 57 to be in contact with the protrusion 41a1 of the bottom lid 41a is wide at the base, and the portion where the protrusion 41a1 of the bottom lid 41a at the front end is narrowed, the bottom lid 41a should not be opened. Thus, the wide portion of the opening plate 57 does not contact the bottom lid 41a, and there is no possibility that the bottom lid 41a opens.
