していた。(b) Prior Art Conventionally, a combine harvester in which the grain culm harvested by a reaping device is fed to a threshing device using a vertical conveying device that also controls the handling depth for threshing processing was developed in 1973-
This combine harvester is already known from Publication No. 17795, etc., and this combine is provided with a grain culm lifting section at the front of the threshing device, and the grain culm transferred from the end of the vertical conveying device to the grain culm lifting section is transferred. , held by a guide rod pivoted above the starting end of the grain culm clamping conveyor attached to the threshing device,
The terminal end of the guide rod was inserted between the starting end of the feed chain and the clamping rail that constituted the grain culm clamping and conveying body.
また、刈取穀稈を脱穀する時は前記ガイド杆を
上方へ退避回動させて穀稈挟持搬送体の始端部上
方で係止していた。 Further, when threshing the harvested grain culm, the guide rod is retracted and rotated upward and is locked above the starting end of the grain culm clamping and conveying body.
更に、前記縦搬送装置の後部に穀稈揚送部に指
向するガイド杆を付設することも既に知られてい
る。 Furthermore, it is already known to equip the rear part of the longitudinal conveying device with a guide rod pointing toward the grain lifting section.
(ハ) 考案が解決しようとする問題点
前記既知のコンバインにおけるガイド杆は脱穀
装置の穀稈挟持搬送体の形状に規制されて作動が
不円滑で、穀稈が詰つたり、それによりガイド杆

の受継が不確実で稈漏れや稈詰りを生じた。(c) Problems to be solved by the invention The guide rod in the known combine harvester is restricted by the shape of the grain culm holding conveyor of the threshing device, and its operation is not smooth. In addition, although the end of the vertical conveying device moves up and down when adjusting the handling depth, the guide rod only rotates around the top depending on the amount of culm. As a result, the inheritance of grain culms from the vertical conveyance device was uncertain, resulting in culm leakage and culm clogging.
また、ガイド杆の係止位置が脱穀装置の穀稈挟
持搬送体の上方にあつたので、係脱操作位置が高
くなり操作が困難であつた。 Furthermore, since the locking position of the guide rod was above the grain culm clamping and conveying body of the threshing device, the locking/unlocking operation position was high and the operation was difficult.
更に、ガイド杆を縦搬送装置の後部に付設した
ものは縦搬送装置が傾動すると、ガイド杆と一体
的に傾動して穀稈揚送部に対する位置及び角度が
変化するため穀稈の受継が不円滑であつた。 Furthermore, if the guide rod is attached to the rear of the vertical conveyance device, when the vertical conveyance device tilts, the guide rod and the guide rod will tilt together, changing the position and angle with respect to the grain culm lifting section, making it impossible to inherit the grain culm. It was smooth and warm.

題を解決した。(d) Means for solving the problem The present invention provides a grain culm lifting section in front of the supply port of the threshing device, a guide rod is attached to the conveying surface of the grain culm lifting section, and the guide rod The base of the guide rod is rotatably supported back and forth at a position corresponding to or in the vicinity of the horizontal axis, which is the tilting center of the vertical conveyance device, in side view, and the tip of the guide rod is positioned near the starting end of the grain culm clamping conveyance body. Although a locking device is provided to releasably lock the guide rod and the guide rod rotates according to the amount of culm to be lifted, ensuring reliable lifting, the vertical conveying device does not have enough handling depth. When the guide rod is moved up and down to adjust the grain height, the base of the guide rod is rotated near the center of tilt of the vertical conveying device, and the relative position with the grain culm lifting section is kept approximately constant, thereby ensuring the inheritance of the grain culm. In addition, the above-mentioned problems are solved by making it possible to engage and disengage the guide lever easily by operating the guide lever.
(ホ) 作用
刈取装置で刈取つた穀稈は縦搬送装置により後
送され、その搬送終端から穀稈揚送部を経て脱穀
装置の穀稈挟持搬送体に受継され、挟持搬送され
る間に脱穀装置により脱穀処理される。(E) Effect Grain culm harvested by the reaping device is transported later by a vertical conveyance device, and from the end of the conveyance, it is passed through the grain culm lifting section to the grain culm clamping conveyance body of the threshing device. The grain is threshed using a device.
そして、前記穀稈受継時にガイド杆は下部を中
心として稈量に順応して回動するので、前記穀稈
挟持搬送体の形状の影響を受けることがなく、ま
た、扱深さ調節を行なうべく、縦搬送装置を上下
傾動させた時、ガイド杆の基部は縦搬送装置の傾
動中心になる横軸の近傍を回動中心として回動す
るので、穀稈揚送部に対する関係位置が殆ど変化
せず、確実な穀稈受継を行なうことができる。 When the grain culm is transferred, the guide rod rotates around the lower part according to the amount of culm, so it is not affected by the shape of the grain culm holding conveyance body, and the handling depth can be adjusted. When the vertical conveyance device is tilted up and down, the base of the guide rod rotates around the horizontal axis, which is the center of tilt of the vertical conveyance device, so its relative position with respect to the grain culm lifting section hardly changes. Therefore, it is possible to ensure grain culm inheritance.
また、手刈穀稈を脱穀すべく、ガイド杆の上部
を係止位置に係脱する時、ガイド杆の操作により
低い位置で容易に係脱することができる。 Further, when the upper part of the guide rod is engaged and disengaged from the locking position in order to thresh the hand-cut grain culm, the upper part of the guide rod can be easily engaged and disengaged from a lower position by operating the guide rod.
