【考案の属する技術分野】[Technical field to which the invention belongs]

本考案は刈取部及び脱穀部を備え、連続的に穀稈を刈取って脱穀するコンバイ ンに関する。 The present invention relates to a combiner having a mowing part and a threshing part, for continuously mowing and threshing grain culms.

【0002】[0002]

【従来の技術】[Prior art]

従来、扱深調節アーム及びロッドを設け、穀稈搬送チェンに扱深調節ロッドを 連結させると共に、扱深モータによって扱深調節アームを揺動させ、前記搬送チ ェンを揺動変位させて扱深調節を行う技術があった。 Conventionally, a handling depth adjusting arm and a rod are provided, and the handling depth adjusting rod is connected to the grain transfer chain, and the handling depth adjusting arm is swung to swing and displace the transport chain. There was a technique to make deep adjustments.

【考案が解決しようとする課題】[Problems to be solved by the device]

前記従来技術は、扱深調節アームの揺動範囲を設定するリミットスイッチの移 動、並びに扱深調節ロッドの連結長さの変更により、前記搬送チェンの扱深調節 範囲を変化させる微調節を行っていたが、極短稈または極長稈のように扱深調節 範囲を大幅に変更させる必要があるとき、穀稈搬送チェンの位置設定を容易に行 い得ないと共に、短稈または長稈限度位置に設定しているときにはそれ以上の微 調節が行い得ない等の問題があった。 In the above-mentioned prior art, fine adjustment is performed to change the handling depth adjustment range of the transfer chain by moving a limit switch that sets the swinging range of the handling depth adjustment arm and changing the connection length of the handling depth adjustment rod. However, when it is necessary to change the handling depth adjustment range drastically like extremely short culm or extremely long culm, it is not possible to easily set the position of the grain culm transport chain and the short culm or long culm limit is set. There was a problem such as not being able to perform further fine adjustment when set to the position.

A handle depth adjusting rod whose one end is rotatably connected to the tip of the depth adjusting arm, a shaft body whose one end is connected to the chain guide rail of the grain transfer chain, and a joint which is rotatably attached to the other end of the shaft body are provided. The tip end of the handle depth adjusting rod is screwed to the joint at a position deviated from the center of rotation, and the handle depth adjusting range is finely adjusted by changing the connection length of the handle depth adjusting rod to the joint. By reversing, the connecting position with the handling depth adjustment rod is moved toward and away from the pivot axis of the grain culm transport chain, and the handling depth adjustment range is greatly changed to the extremely short culm side and the extremely long culm side. It is possible to obtain two types of handling depth adjustment ranges, namely, an extremely short culm handling depth adjustment range and an extremely long culling handling depth adjustment range corresponding to culms and extremely long culms, and it is possible to easily change the handling depth adjustment range drastically. However, fine adjustment of the handling depth adjustment range at the change destination can be properly performed, and the adaptive culm length of the handling depth adjustment can be greatly expanded compared to the conventional one.

1. A combine depth adjusting arm for swinging by a handle depth motor and a handle depth adjustment in a combine for adjusting the handle depth of a grain culm by rotatively displacing a grain culm transport chain about a fulcrum shaft by a handle depth motor. The handle depth adjusting rod whose one end is rotatably connected to the arm tip, the shaft body whose one end is connected to the chain guide rail of the grain transfer chain, and the joint which is rotatably attached to the other end of the shaft body are provided. The tip of the depth adjusting rod is screwed to the joint at a position off this center of rotation, and the handling depth adjusting range is finely adjusted by changing the connecting length of the handling depth adjusting rod to the joint.
By reversing the joint, the connection position with the handling depth adjusting rod is brought into contact with and separated from the rotation fulcrum axis of the grain culm transport chain, and the handling depth adjustment range can be changed significantly to the extremely short culm side and the extremely long culm side. Characteristic combine.
