Description

本発明は、田植機等の移植機に関する。   The present invention relates to a transplanter such as a rice transplanter.

従来圃場に苗を植え付ける植付部と、回転駆動されて圃場を掻き整地（代掻き）する代掻きロータとを備え、該代掻きロータを植付部の前方に横設した植付作業機が公知となっており、該植付作業機を走行機体に連結し、予め代掻きを行うことなく、代掻きと同時に植え付けを行う代掻同時移植機が知られている（例えば特許文献１参照）。
特許第３０７５６６１号公報 2. Description of the Related Art Conventionally, a planting work machine having a planting unit for planting seedlings in a farm field and a scraping rotor that is driven to rotate and scrapes the field (scraping), and in which the scraping rotor is installed in front of the planting part has become known. In addition, there is known a bone graft simultaneous transplanting machine in which the planting work machine is connected to a traveling machine body, and planting is performed at the same time as the blanking without performing the blanking in advance (see, for example, Patent Document 1).
Japanese Patent No. 3075661

しかし一般的には、植え付け作業とは別に予め代掻き作業を行い、その後田植え機等で植え付け作業を行う農家も多く、この場合植え付け作業時に走行機体の車輪で圃場を荒らすことがあり、車輪等で荒れた部分のみを整地することができる簡単な装置が望まれていた。   However, in general, there are many farmers who perform cutting work in advance separately from planting work and then planting work with a rice planting machine, etc.In this case, the farm field may be roughened with the wheels of the traveling machine body at the time of planting work. A simple device capable of leveling only a rough part has been desired.

上記課題を解決するための本発明の移植機は、走行機体３に連結され、圃場に苗を植え付ける植付部１２を備え、植付部１２の前方に、代掻き後の植付作業時に圃場の表面から植付け深さまでの圃場表層の整地作業を行う整地ロータ１３を設け、整地ロータ１３を、回転に伴って圃場面を掻く複数の整地部材３７と、該整地部材３７を連結して全体として篭型を形成せしめる連結部材３８とから構成し、各整地部材３７のランニング軌跡が、所定の整地部材３７ａのランニング軌跡αと、該整地部材３７ａに対する回転方向の１つ前の整地部材３７ｂのランニング軌跡βとが、側面視で圃場表面近傍で交差するように、整地ロータ１３を走行機体３の走行速度に連動して駆動するにあたり、整地部材３７が圃場面を押え付けるように倒伏しながら圃場表層に入るとともに起立しながら圃場表層を抜け出ることを特徴としている。 The transplanter of the present invention for solving the above-mentioned problems is provided with a planting unit 12 that is connected to the traveling machine body 3 and plants seedlings in the field, and is placed in front of the planting unit 12 at the time of planting work after cutting. A leveling rotor 13 that performs leveling work on the surface of the field from the surface to the planting depth is provided , and the leveling rotor 13 is connected to a plurality of leveling members 37 that scratch the field scene with rotation and the leveling member 37 is connected as a whole. The running track of each leveling member 37 includes a running track α of a predetermined leveling member 37a and a running track of a leveling member 37b immediately before the rotational direction with respect to the leveling member 37a. When driving the leveling rotor 13 in conjunction with the traveling speed of the traveling machine body 3 so that β intersects the field surface vicinity in a side view, the leveling member 37 does not fall down so as to press the field scene. It is a feature that exit the field surface while standing with entering Luo field surface.

以上のように構成される本発明の構造によると、整地ロータによって、圃場表層の整地作業を行うことができるため、代掻き後の圃場で植え付け作業を行う場合、上記整地ロータによって走行機体の車輪跡等を整地し、安定した植え付け作業を円滑に行うことができるという効果がある。そして本整地ロータは圃場の表面から植付け深さまでという従来の代掻き田植え機より浅い圃場の極表層側を整地するのみでよいため、整地ロータの駆動力が比較的小さくて済み、さらに整地ロータ自体に大きな強度が必要ないため、樹脂等の比較的軽量な材質で形成することができるという効果もある。   According to the structure of the present invention configured as described above, since the leveling work on the surface of the field can be performed by the leveling rotor, when performing planting work in the field after scraping, the wheel mark of the traveling machine body is set by the leveling rotor. It has the effect of leveling the ground and the like and performing a stable planting operation smoothly. And since this leveling rotor only needs to level the pole surface of the field shallower than the conventional paddy rice planting machine from the surface of the field to the planting depth, the driving force of the leveling rotor can be relatively small, and the leveling rotor itself Since large strength is not required, there is an effect that it can be formed of a relatively light material such as resin.

また整地ロータを、各整地部材のランニング軌跡が、所定の整地部材と、該整地部材に対する回転方向の１つ前の整地部材のランニング軌跡とが、側面視で圃場表面近傍で交差するように、整地ロータを走行機体の走行速度に連動して駆動することによって、走行速度の変化に伴い整地ロータの駆動速度が変更され、各整地部材による整地作業（圃場を掻く作業）は、圃場の表面より内部でのオーバラップが概ね無く、代掻き後の圃場を必要以上に掻くことが無いため、代掻き過ぎによる苗の生育悪化等を防止することができるという効果がある。   Further, the leveling rotor is configured so that the running trajectory of each leveling member intersects the predetermined leveling member and the running trajectory of the leveling member immediately before the leveling member in the rotation direction with respect to the leveling member near the field surface in a side view. By driving the leveling rotor in conjunction with the traveling speed of the traveling machine body, the driving speed of the leveling rotor is changed as the traveling speed changes, and the leveling work (work for scratching the field) by each leveling member is performed from the surface of the field. Since there is almost no internal overlap and the field after scraping is not scratched more than necessary, it is possible to prevent the deterioration of seedling growth due to excessive scraping.

次に本発明の１実施形態を図面に基づいて説明する。図１は本発明の整地ロータを備えた移植機である乗用田植機の側面図であり、該乗用田植機は従来同様、前後輪１，２に支持された走行機体３の後方に、植付作業機４が昇降リンク６を介して昇降自在、且つローリング可能に連結された構造となっている。   Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a riding rice transplanter that is a transplanter equipped with a leveling rotor according to the present invention. The riding rice transplanter is planted behind a traveling machine body 3 supported by front and rear wheels 1 and 2 as in the prior art. The work machine 4 is connected via a lifting link 6 so as to be movable up and down and rollable.

上記植付作業機４における苗載せ台７の正面（裏面）側には、図１，図２に示されるように、縦方向の縦フレーム８と、該縦フレーム８に一体的に固定され、縦フレーム８の下方に左右方向に横設されている横フレーム９とが設けられている。そして上記横フレーム９側に、複数のプランタケース１１が取り付けられており、該プランタケース１１に苗の植付け用のビーク１２が設けられている。   As shown in FIGS. 1 and 2, on the front (back surface) side of the seedling platform 7 in the planting work machine 4, the vertical frame 8 in the vertical direction and the vertical frame 8 are fixed integrally. A horizontal frame 9 is provided below the vertical frame 8 in a horizontal direction. A plurality of planter cases 11 are attached to the side of the horizontal frame 9, and beaks 12 for planting seedlings are provided on the planter case 11.

またプランタケース１１の下方には、左右方向に複数のフロート１０が設けられており、本乗用田植機は、フロート１０が圃場面に接地するように植付作業機４を下降させ、走行機体３を走行させながらビーク１２を回転駆動することによって、ビーク１２が苗載せ台７上の苗を掻きとって圃場に植え付ける構造となっている。なお本乗用田植機は代掻同時移植機ではないため、代掻き後の圃場への苗の植付作業を行う。   A plurality of floats 10 are provided below the planter case 11 in the left-right direction. The riding rice transplanter lowers the planting work machine 4 so that the float 10 contacts the field scene, and the traveling machine body 3 By rotating the beak 12 while traveling, the beak 12 scrapes off the seedlings on the seedling mount 7 and plantes them in the field. In addition, since this riding rice transplanter is not a simultaneous skin grafting machine, seedlings are transplanted to the field after the ground scraping.

さらに植付作業機４側には、ビーク１２の前方且つ後輪２の後方に、ビーク１２と後輪２との間に位置するように、植付作業機４の略全幅にわたって複数の整地ロータ１３が支点軸（ロータ軸）１４に回転駆動自在に軸支されて設けられており、該整地ロータ１３を圃場内に挿入して回転駆動することにより、上記植付け作業時に走行機体３の旋回等により荒れた代掻き後の圃場の枕地等の整地を行い、整地後の圃場に苗を植え付けることが可能となっている。   Further, on the planting work machine 4 side, a plurality of leveling rotors are disposed over substantially the entire width of the planting work machine 4 so as to be positioned between the beak 12 and the rear wheel 2 in front of the beak 12 and behind the rear wheel 2. 13 is pivotally supported by a fulcrum shaft (rotor shaft) 14 and is provided so as to be rotatably driven. The ground leveling rotor 13 is inserted into the field and rotated to thereby rotate the traveling machine body 3 during the planting operation. It is possible to perform leveling such as a headland in a field after rough scraping and to plant seedlings in the field after leveling.

次に上記整地ロータ１３の支持構造について説明する。上記両縦フレーム８の上方側間には、左右方向の軸１６が回動自在に軸支されており、該軸１６の左右両側には上アーム１７が突設されている。また左右の各縦フレーム８の下方側には、下アーム２０が揺動自在に軸支されている。   Next, the support structure for the leveling rotor 13 will be described. Between the upper sides of the vertical frames 8, left and right shafts 16 are rotatably supported, and upper arms 17 project from left and right sides of the shafts 16. A lower arm 20 is pivotally supported on the lower side of the left and right vertical frames 8 so as to be swingable.

そして左右の各上アーム１７の先端側と左右の各下アーム２０の先端側との間に、それぞれ縦アーム１８が軸支されており、左右の各縦アーム１８の下端側間に、ロータ軸１４を介して整地ロータ１３が左右方向に複数軸支されている。なお整地ロータ１３は、左右方向の略中央に設けられるギヤケース１５からの駆動力によって回転駆動される。   A vertical arm 18 is pivotally supported between the distal end side of each of the left and right upper arms 17 and the distal end side of each of the left and right lower arms 20, and a rotor shaft is interposed between the lower end sides of each of the left and right vertical arms 18. A plurality of leveling rotors 13 are supported in the left-right direction via 14. The leveling rotor 13 is rotationally driven by the driving force from the gear case 15 provided at the approximate center in the left-right direction.

このとき軸１６にはレバー２３が突設されており、該レバー２３は縦フレーム８に固定されたレバーガイド２４に挿通されている。このためレバー２３の揺動によって軸１６を回動させると、アーム１７，ロッド１８を介して整地ロータ１３が昇降して高さが調節され、レバー２３をレバーガイド２４に設けられた複数の段部のいずれかに係止することによって整地ロータ１３の高さが段階的に位置決め調節される。   At this time, a lever 23 protrudes from the shaft 16, and the lever 23 is inserted into a lever guide 24 fixed to the vertical frame 8. Therefore, when the shaft 16 is rotated by swinging the lever 23, the leveling rotor 13 is moved up and down via the arm 17 and the rod 18 to adjust the height, and the lever 23 is provided with a plurality of steps provided on the lever guide 24. The height of the leveling rotor 13 is adjusted in stages by engaging with any of the sections.

上記各整地ロータ１３は、図３（ａ），（ｂ）に示されるように、ロータ軸１４を挟んで対称に２分割されており、２つの同一形状の分割片３６，３６の組み合わせによって構成され、全体として側面視で正６角形となる篭型をなしている。そして各分割片３６は回転に伴って圃場面を掻く複数の板状の整地部材３７と、該整地部材３７を左右両側において連結する連結部材３８とから構成されている。なお両分割片３６は、それぞれ整地部材３７と連結部材３８とが樹脂によって一体成形されている。   As shown in FIGS. 3A and 3B, each leveling rotor 13 is divided into two symmetrically with the rotor shaft 14 in between, and is constituted by a combination of two pieces 36 and 36 having the same shape. As a whole, it has a saddle shape that is a regular hexagon in a side view. Each divided piece 36 is composed of a plurality of plate-shaped leveling members 37 that scratch the field scene as it rotates, and connecting members 38 that connect the leveling members 37 on both the left and right sides. In each of the divided pieces 36, a leveling member 37 and a connecting member 38 are integrally formed of resin.

そして連結部材３８の支点軸１４を挟んだ両側には、２つの分割片３６を固定するボルト４２を取り付けるためのボルト座４３と、ナット４４を収容するためのナット孔４６が形成されている。また各連結部材３８にはロータ軸１４を挿通させる半円状の切欠部が形成されている。   A bolt seat 43 for attaching a bolt 42 for fixing two divided pieces 36 and a nut hole 46 for receiving a nut 44 are formed on both sides of the fulcrum shaft 14 of the connecting member 38. Each connecting member 38 is formed with a semicircular cutout portion through which the rotor shaft 14 is inserted.

これにより一方の分割片３６のボルト座４３と他方の分割片３６のナット孔４６とを対向させ、且つ切欠部でロータ軸１４を挟持するように、両分割片３６をロータ軸１４の周面側から取り付け、この際ロータ軸１４に直交してピン４９を挿入し、さらに該ピン４９の両端を各分割片３６側に挿入し、両分割片３６をボルト４２及びナット４４で固定することによって、整地用ロータ１３がロータ軸１４に一体的回転するように取り付けられる。なおボルト４２及びナット４４による固定を解除することによって、両分割片３６をロータ軸１４の周面側から取り外す（整地用ロータ１３を分解する）ことができる。   Thus, the two split pieces 36 are arranged on the peripheral surface of the rotor shaft 14 so that the bolt seat 43 of one split piece 36 and the nut hole 46 of the other split piece 36 face each other and the rotor shaft 14 is held between the notches. At this time, by inserting pins 49 perpendicular to the rotor shaft 14, inserting both ends of the pins 49 into the respective divided pieces 36, and fixing both divided pieces 36 with bolts 42 and nuts 44. The leveling rotor 13 is attached to the rotor shaft 14 so as to rotate integrally. By releasing the fixing by the bolts 42 and the nuts 44, the two split pieces 36 can be removed from the peripheral surface side of the rotor shaft 14 (the ground leveling rotor 13 is disassembled).

一方上記整地ロータ１３は、前述のようにレバー２３によって高さ調節が行われ、フロート１０の下面より下方に突出させられると、フロート１０からの突出量分圃場に挿入され、整地作業を行うことが可能となる。ただし本整地ロータ１３の高さは、整地ロータ１３の圃場に挿入される最深深さが、植付け深さＺ未満（植付深さＺより表面側）となる範囲（図４参照）での調節が可能となっており、これにより整地ロータ１３は圃場の植付深さＺより浅い表層部分Ｙ（図４参照）のみを整地するものとなっている。なお本実施形態において整地ロータ１３は、フロート１０の下面からの突出量が概ね１０〜４０ｍｍの範囲で調節が可能であり、上記植付作業時の植付深さＺより浅い表層部分Ｙの整地を可能としている。   On the other hand, when the height of the leveling rotor 13 is adjusted by the lever 23 as described above and protrudes downward from the lower surface of the float 10, it is inserted into the field by the amount of protrusion from the float 10 to perform leveling work. Is possible. However, the height of the leveling rotor 13 is adjusted in a range (see FIG. 4) in which the deepest depth inserted into the field of the leveling rotor 13 is less than the planting depth Z (surface side from the planting depth Z). As a result, the leveling rotor 13 leveles only the surface layer portion Y (see FIG. 4) shallower than the planting depth Z of the field. In the present embodiment, the leveling rotor 13 can be adjusted in a range where the protruding amount from the lower surface of the float 10 is approximately 10 to 40 mm, and the leveling of the surface layer portion Y shallower than the planting depth Z at the time of the planting operation. Is possible.

これにより植付深さ（従来同様変更可能）に合わせて整地ロータ１３の高さを調節し、整地ロータ１３を圃場に挿入して回転駆動することによって、整地ロータ１３が圃場の植付深さＺより浅い表層部分Ｙのみを整地し、前述のように植付け作業時に走行機体３の旋回等により走行機体３の車輪跡等で荒れた代掻き後の圃場、特に枕地等の整地を行い、整地後の圃場に対して苗の安定した植え付け作業を円滑に行うことができる。   Thereby, the height of the leveling rotor 13 is adjusted according to the planting depth (which can be changed as in the prior art), and the leveling rotor 13 is inserted into the field and driven to rotate, whereby the leveling rotor 13 is planted in the field. Only the surface portion Y shallower than Z is leveled, and as described above, leveling of the field after the scraping, especially the headland, which has been roughed by the wheel marks of the traveling machine 3 due to turning of the traveling machine 3 during the planting operation, etc. A stable planting operation of the seedling can be smoothly performed on the subsequent farm field.

一方代掻き後の圃場は再度代掻き又は代掻きと同様の整地を行うと、代掻き過ぎの状態となり、苗の生育悪化等の不都合が発生することが知られている。そして本整地ロータ１３は代掻き後の圃場への植付け作業時に使用するものであり、本整地ロータ１３を使用することによって代掻き過ぎとなることを防止するように、図４に示されるように、各整地部材３７のランニング軌跡が、所定の整地部材３７ａのランニング軌跡αと、該整地部材３７ａに対する回転方向の１つ前の整地部材３７ｂのランニング軌跡βとが、側面視で圃場表面近傍のＡ部分で交差するように回転速度が設定されている。なお図４は、走行機体３の走行に伴う２つの整地部材３７ａ，３７ｂの位置を１６段階で時系列的に示したものである。   On the other hand, it is known that when the field after the pricking is performed again, the plowing or the same leveling as the pricking is performed, the state becomes excessively pricked and inconveniences such as deterioration of seedling growth occur. And this leveling rotor 13 is used at the time of planting work in the field after cutting, and as shown in FIG. 4, as shown in FIG. The running trajectory of the leveling member 37 includes a running trajectory α of a predetermined leveling member 37a and a running trajectory β of the leveling member 37b immediately before the leveling member 37a in the rotational direction. The rotation speed is set so as to intersect at. FIG. 4 shows the positions of the two leveling members 37a and 37b accompanying the traveling of the traveling machine body 3 in a time series in 16 stages.

また図１に示されるように、整地ロータ１３用のギヤケース１５には、後輪２のトランスミッション２５から駆動力が伝動されており、走行速度を変更すると、走行速度に追従して整地ロータ１３の回転速度が変更され、走行速度が変更された場合も、常に上記のように所定の整地部材３７ａのランニング軌跡αと、該整地部材３７ａに対する回転方向の１つ前の整地部材３７ｂのランニング軌跡βとが、側面視で圃場表面近傍で交差する。   Further, as shown in FIG. 1, the driving force is transmitted from the transmission 25 of the rear wheel 2 to the gear case 15 for the leveling rotor 13, and when the traveling speed is changed, the grounding rotor 13 follows the traveling speed. Even when the rotational speed is changed and the traveling speed is changed, the running trajectory α of the predetermined leveling member 37a and the running trajectory β of the leveling member 37b immediately before in the rotational direction with respect to the leveling member 37a as described above. Crosses near the field surface in a side view.

これにより整地ロータ１３の各整地部材３７による整地作業（圃場を掻く作業）は、どのような走行速度であっても、圃場の表面ではオーバラップし、圃場の表面より内部でのオーバラップがほとんど無い。すなわち圃場表面においては掻き残しを発生させずに全面の整地を行い、圃場内部には掻き残しを発生させるように粗く整地作業を行う。   Thereby, the leveling work (work for scratching the field) by each leveling member 37 of the leveling rotor 13 overlaps on the surface of the field at any traveling speed, and there is almost no overlap inside the surface of the field. No. That is, the entire surface of the field is leveled without generating scraping, and the leveling operation is roughly performed so as to generate scraping within the field.

このため代掻き後の圃場を必要以上に掻くことが無く、代掻き過ぎによる苗の生育悪化等が防止されるとともに、圃場表面においては掻き残しを発生させずに植付作業機３の略全幅に亘って整地するため、代掻き後に圃場に落ちた雑草の種や雑草を土中に掻き込むことで、除草効果を奏する。そして整地作業が植付深さＺに達しないため、苗の根の部分の土壌が軟らかくなり過ぎることは無く、苗の植え付け姿勢が安定し、苗が起立し、苗の倒伏が少ない。   For this reason, the field after scraping is not scratched more than necessary, the deterioration of seedling growth due to excessive scraping is prevented, and the entire surface of the planting work machine 3 is not generated on the surface of the field without causing scraping. In order to level the ground, weeding seeds and weeds that have fallen into the field after scraping are effective for weeding. And since the leveling work does not reach the planting depth Z, the soil of the root part of the seedling does not become too soft, the planting posture of the seedling is stabilized, the seedling stands up, and there is little lodging of the seedling.

また整地ロータ１３の回転速度が走行機体３の走行速度に連動することによって圃場面上の泥土や泥水を一定の速度で後方に移動させることができ、フロート１０の前方への泥土や泥水溜まりや、整地ロータ１３前方への泥土や泥水溜まりを防止し、泥土や泥水による植付不良も防止する。このために整地ロータ１３の周速度は走行機体３の車速に対して１．５〜２．５倍、すなわち走行速度１m/sに対して1.5〜2.5m/sに設定されている。   Further, the rotational speed of the leveling rotor 13 is linked to the traveling speed of the traveling machine body 3 so that mud and mud on the farm scene can be moved backward at a constant speed, and mud and mud pool in front of the float 10 Further, mud and mud pool in the front of the leveling rotor 13 are prevented, and planting defects due to mud and mud are also prevented. For this reason, the circumferential speed of the leveling rotor 13 is set to 1.5 to 2.5 times the vehicle speed of the traveling machine body 3, that is, 1.5 to 2.5 m / s with respect to the traveling speed 1 m / s.

そして上記整地ロータ１３は前述のように圃場の極表層側を整地するのみであるため、整地ロータ１３の駆動力が比較的小さくて済み、このため前述のように他のトランスミッション（本実施形態においては後輪２の駆動用のトランスミッション２５）から駆動力を分岐して取り出すことができ、整地ロータ１３の駆動機構を簡単に構成することができる。   Since the leveling rotor 13 only leveles the pole surface side of the field as described above, the driving force of the leveling rotor 13 may be relatively small. Therefore, as described above, another transmission (in this embodiment) Can branch out the driving force from the transmission 25) for driving the rear wheel 2, and the drive mechanism of the leveling rotor 13 can be simply configured.

また整地部分が前述のように圃場の極浅い表層であるため、整地ロータ１３自体に大きな強度が必要ないため、本実施形態のように樹脂や樹脂等の比較的軽量な材質で形成することができ、整地ロータ１３の構造を簡単にすることができる他、軽量であるため駆動力をより小さくすることができ、さらに整地ロータ１３を持たない乗用田植機等に簡単にオプションとして取り付けることができる。   In addition, since the leveling portion is an extremely shallow surface layer of the field as described above, the leveling rotor 13 itself does not need to have a large strength. Therefore, as in this embodiment, the leveling portion can be formed of a relatively light material such as resin or resin. In addition to simplifying the structure of the leveling rotor 13, it is light in weight so that the driving force can be further reduced, and can be easily attached as an option to a riding rice transplanter or the like that does not have the leveling rotor 13. .
