Description

本発明は、刈取装置の分草された穀稈を引起こす引起装置等に電動モータの出力回転を伝動して駆動するコンバインに関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine which is driven by transmitting the output rotation of an electric motor to a pulling device or the like of a reaping device for pulling up divided grain culms.

従来のコンバインにおいて、刈取装置の引起装置等にエンジンの出力回転を伝動して駆動する技術が知られていた。（特許文献１参照） In a conventional combine harvester, a technique is known in which the output rotation of an engine is transmitted to a triggering device of a harvesting device to drive the harvester. (See Patent Document 1)

特開２０１４－００７９８５号公報JP 2014-007985 A

しかし、特許文献１の技術では、エンジンの出力回転を引起装置等に伝動する前後方向に延在する回転軸のたわみ等を防止するために、この回転軸が内装される刈取装置の主枠を形成して刈取装置を昇降させる伝動筒の肉厚を厚くして剛性を高める必要がある。これにより、伝動筒自体の重量が重くなるので刈取装置の昇降に大きな操作力が必要になるという問題が有った。 However, in the technique disclosed in Patent Document 1, in order to prevent deflection of the rotating shaft extending in the front-rear direction that transmits the output rotation of the engine to the triggering device, etc., the main frame of the reaper in which the rotating shaft is installed is installed. It is necessary to increase the rigidity by increasing the thickness of the transmission cylinder that is formed to move the reaper up and down. As a result, the weight of the transmission tube itself becomes heavy, and there is a problem that a large operating force is required to move the reaper up and down.

そこで、本発明の主たる課題は、エンジンの出力回転が伝動される回転軸に加わる負荷を削減して回転軸のたわみ等を抑制して、伝動筒自体の重量を軽くして刈取装置の昇降を小さな操作力で容易に行うことができるコンバインを提供することにある。 Therefore, the main object of the present invention is to reduce the load applied to the rotating shaft to which the output rotation of the engine is transmitted, suppress the bending of the rotating shaft, etc., reduce the weight of the transmission cylinder itself, and raise and lower the reaper. To provide a combine that can be easily operated with a small operating force.
