本発明は、田植機において、稚苗、中成苗、成
苗などの植付苗の種類、あるいは、植付苗の条間
や株間の程度に合わせて、植付苗の取り量調節を
行うための植付装置の苗取り量調節装置の改良に
関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a rice transplanter to control the types of seedlings to be planted, such as young seedlings, mid-grown seedlings, and adult seedlings, or the distance between rows and plants of the planted seedlings. The present invention relates to an improvement in a device for adjusting the amount of seedlings taken out of a planting device for adjusting the amount of seedlings to be planted depending on the level of seedlings.

昭56−32909号公報参照）。
Conventionally, as a seedling removal amount adjusting device of this type of planting device, when adjusting the amount of seedling removal by changing the movement locus of the planting claw of the planting device, the connection point between the planting claw and the fixed part is used. The position of the swinging fulcrum in is changed manually by rotating the screw shaft or pushing and pulling in the direction of the screw shaft axis, and the movement trajectory of the tip of the planting claw is adjusted relative to the seedling outlet of the seedling stand. The position was changed back and forth in the direction of sending out the seedlings (see, for example, Japanese Patent Application Laid-Open No. 56-32909).
しかしながら、上記従来の調節手段では、目測
と手動により苗取り量を予め植付作業前に調節し
ておく構成でしかないため、次のような問題があ
つた。
However, with the above-mentioned conventional adjustment means, the amount of seedlings to be removed can only be adjusted in advance by visual measurement and manually before the planting operation, and therefore the following problems occurred.
すなわち、植付爪による苗の分割は、苗のせ台
に載置されているマツト苗の床土部分に対して、
その端縁から所定寸法だけ苗送り出し方向の上手
側に植付爪を突入させ、その苗床土部分を植付爪

あると、所定量ずつ正確に苗分割を行つても、そ
のバラツキの程度によつて、植付爪が苗の植わつ
ていない床上部分を分割して、欠株を生じる虞が
あつた。 In other words, when dividing seedlings using the planting claw, the soil part of the pine seedlings placed on the seedling stand is divided into two parts.
This is done by inserting a planting claw into the upper side of the seedling feeding direction by a predetermined distance from the edge of the seedling, and scraping off the seedbed soil with the planting claw. No matter how accurately you set the position of the planting claw from the edge of the seedbed soil, if there are variations in the planting spacing of the seedlings on the seedbed soil, it will be difficult to accurately divide the seedlings by a predetermined amount. However, depending on the degree of variation, there was a risk that the planting claws would divide the upper part of the bed where no seedlings were planted, resulting in missing plants.
また、植付爪の揺動支点位置を螺軸の回動操作
などで調節するものであるため、前記植付爪の作
動毎に苗取り量を調節することは不可能であり、
苗の植付け間隔の変化に応じてその都度調節する
ことができないものであつた。 In addition, since the swinging fulcrum position of the planting claw is adjusted by rotating the screw shaft, it is impossible to adjust the amount of seedlings taken each time the planting claw is operated.
It was not possible to adjust each time according to changes in the planting interval of seedlings.
本発明の目的は、苗供給装置より供給される苗

先端移動軌跡を調節可能な田植機の苗取り量調節
装置を提供することにある。 An object of the present invention is to automatically detect seedling positions even if there are variations in the planting interval of seedlings supplied from a seedling supply device, and to avoid the effects of changes in the seedling positions caused by sending out the seedlings. An object of the present invention is to provide a seedling removal amount adjusting device for a rice transplanter capable of adjusting the moving locus of the tip of a planting claw so as to reliably divide and take out the upper part of the bed where the seedlings are located.
上記目的を達成するために講じた本発明の技術
手段は、植付爪先端の移動軌跡を苗供給装置に対

断すべく構成したことである。
The technical means of the present invention taken to achieve the above object includes providing a planting claw trajectory adjusting device that can adjust the movement trajectory of the tip of the planting claw in the direction of distance with respect to the seedling supply device, and A seedling position detection sensor is provided to detect the position of the seedlings supplied from the seedling, and the trajectory adjustment device is controlled based on the seedling position detection result of the sensor, so that the tip movement trajectory of the planting claw is automatically adjusted. Further, a switch is provided to detect a state in which the seedling feeding device is located at the end of its movement, and the control of the trajectory adjusting device is suspended while the switch detects the state. That's true.
上記の技術手段を講じたことによる作用は次の
通りである。
The effects of taking the above technical measures are as follows.
即ち、マツト苗の苗床土部分の端縁を基準とし
て爪突入位置を決定するのではなく、マツト苗上
で苗が植わつている部分を検出するセンサーを設
けて、そのセンサーにより、常に実際の苗の存在
位置を検出し、これを基準として爪の突入位置を
設定するものであるから、苗供給装置より供給さ
れる苗の植付け間隔にバラツキがあつても、これ
に自動的に対応させて爪突入位置を調節すること
ができる。 In other words, instead of determining the nail entry position based on the edge of the soil in the nursery bed for pine seedlings, a sensor is installed to detect the part of the pine seedling where the seedling is planted, and the sensor always determines the actual position. Since the position of the seedlings is detected and the plunge position of the claw is set based on this, even if there are variations in the planting interval of the seedlings supplied by the seedling supply device, this can be automatically adjusted. The claw entry position can be adjusted.
しかも、前記苗供給装置がその移動終端部に位
置している状態を検出するスイツチを設けて、こ
のスイツチが前記の移動終端部に位置している状
態を検出している間は、前記軌跡調節装置の制御
を中断するようにしてあるので、この苗供給装置
が移動終端に位置して苗の送り出しが行われてい
る状態での、苗位置の検出結果に基づく植付爪軌
跡の変更は回避できる。 Moreover, a switch is provided for detecting a state in which the seedling feeding device is located at the end of its movement, and while this switch detects a state in which it is located at the end of its movement, the trajectory is adjusted. Since the control of the device is interrupted, it is avoided to change the planting claw trajectory based on the detection result of the seedling position when the seedling feeding device is located at the end of its movement and sending out the seedlings. can.
従つて、苗供給装置より供給される苗の植付け
間隔にバラツキがあつても、そのバラツキによる
影響を受けることなく、確実に苗の存在する状態
で一株分の植付苗を分割でき、欠株の生じる虞の
少ない苗植え付けを行える利点がある。
Therefore, even if there are variations in the planting interval of the seedlings supplied by the seedling supply device, one planted seedling can be reliably divided with the seedlings still present without being affected by the variation, and the seedlings can be divided without any defects. There is an advantage that seedlings can be planted with less risk of seedlings forming.
また、苗供給装置の移動方向転換時における苗
の送り出し途中での軌跡調節装置の制御を回避し
て、植付爪軌跡が不適切な苗位置検出情報に基づ
いて不適切な範囲に調節されるということを避け
易い。 In addition, the control of the trajectory adjustment device during sending out of seedlings when changing the moving direction of the seedling feeding device is avoided, and the planting claw trajectory is adjusted to an inappropriate range based on inappropriate seedling position detection information. It's easy to avoid that.
