Description

【０００１】
【発明の属する技術分野】
刈取部で刈取った稲、麦、豆類など穀物をフィーダハウスを介し脱穀部に全量投入して脱穀処理する普通形コンバインに関する。
【０００２】
【発明が解決しようとする課題】
扱室の前後であって、機体の進行方向に対し軸芯を直交させるスクリュ形扱胴を前後に２つ並設する脱穀構造において、スクリュにより扱胴の軸芯方向に穀物の横送り中に脱穀を行う手段にあっては、第１扱胴の横送り終端で第２扱胴の横送り始端に穀物を受継ぎさせる場合には横送り方向と受継ぎ方向が直交するため、穀物のスムーズな受継ぎが困難となってこの受継ぎ部で穀物の詰まり手段など発生する不都合がある。このため扱室底部の第１扱胴の横送り終端と第２扱胴の横送り始端間に連通樋を介設して、穀物の受継ぎを助長させる手段があるが、連通樋を第１及び第２扱胴の扱室より外側に配設した場合脱穀巾がその分拡大する不都合がある。
【０００３】
また、第１及び第２扱胴の受網に連通樋をラップさせて一体的に設けた場合には受網の取外し時などには連通樋までも取外しを必要とする手間の煩わしさがある。
【０００４】
さらに、網枠の溶接歪やバラツキで扱胴と受網の隙間の調整を必要とする場合にも、網枠の取付位置を調節するなど容易には行えないという問題があった。
【０００５】
またさらに、第１及び第２扱胴の横送り終端に設ける排稈羽根を捩りコイルバネに抗し傾動する可動式とする場合、穀物の詰まり時の排稈羽根などの変形防止などが図れるが、穀物の充分なる投出力の確保が行えないという不都合があった。
【０００６】
【課題を解決するための手段】
したがって本発明は、扱室の前後であって、機体の進行方向に対し軸芯を直交させる２つのスクリュ形第１及び第２扱胴を備えた普通形コンバインにおいて、第１及び第２扱胴の扱室間を連通する連通樋の前後端部を分割して第１及び第２扱胴の案内樋に形成して、第１及び第２扱胴の受網の網枠に案内樋を一体的に設けて、連通樋を扱室内に残したままで受網及び網枠の容易な一体取出しを可能とさせて、受網を脱着させての保守点検作業などの能率を向上させるものである。
【０００７】
また、第１及び第２扱胴を内設する扱室幅内に連通樋を配置させて、連通樋を脱穀部内にコンパクトに組込んで、コンバイン機体の小型化を図るものである。
【０００８】
さらに、第１扱胴の案内樋・連通樋・第２扱胴の案内樋の順に落差を設けて、複数の樋を連結させた組合構造においても、稈の流れを阻害させることなく各樋上をスムーズに稈を移動させて、第１扱胴から第２扱胴への稈の受継ぎを良好とさせるものである。
【０００９】
またさらに、第１扱胴の案内樋・連通樋・第２扱胴の案内樋の順にこれら側壁に横巾を大とさせる段差を設けて、各樋上を稈の移動時各樋の側壁で稈の流れを阻害させることなくスムーズに稈を案内して稈の受継ぎを良好とさせるものである。
【００１０】
また、網枠を支持する枠ガイドレールを脱穀側板に設けると共に、ガイドレールを扱胴の中心半径方向に移動調節可能に設けて、網枠の溶接歪やバラツキなどで扱胴と受網間の隙間を調整する必要がある場合にも、ガイドレールの移動調節によって隙間を容易に適正に保って、脱穀精度を安定維持させるものである。
【００１１】
さらに、連通樋に対応する第１扱胴の送り終端外周に一定の逃げ角を有する排稈羽根を固設させると共に、第２扱胴の送り終端外周に逃げ角０の排稈羽根を固設させて、第１及び第２扱胴の横送り終端における後方への稈の投出力を向上させて、第２扱胴への受継性及び第２扱胴からの排稈性を向上させるものである。
【００１２】

【００１９】
また、第１扱胴軸（２７）とビータ軸（３２）とを連動連結するベルト（５８）にベルトテンション式刈取クラッチ（５９）を設けて、第１扱胴（５）で詰まり事故が発生した場合などにクラッチ（５９）を切とすることによって、ビータ（２９）からの穀稈供給を停止させるように構成している。
【００２０】
さらに、前記フィーダハウス（２１）の左外側に突出させる刈取入力軸である供給チェンコンベア（２５）の駆動軸（６０）にスプロケット（６１）（６２）及びチェン（６３）を介しビータ軸（３２）を連動連結させて、コンベア（２５）と駆動軸（６０）を介する刈取部（１８）の駆動を行うように構成している。
【００２１】
またさらに、第１及び第２扱胴（５）（６）間下方の脱穀左側板（４ａ）外側に走行用カウンタ軸（６４）を設け、エンジン出力軸（４９）にプーリ（６５）（６６）及びベルト（６７）を介し前記カウンタ軸（６４）を連動連結させると共に、機台（１）前側に配備させる走行ミッションケース（６８）の入力軸（６９）にプーリ（７０）（７１）及びベルト（７２）を介し前記カウンタ軸（６４）を連動連結させて、ミッションケース（６８）の出力軸（７３）の走行出力でもって走行クローラ（２）を駆動するように構成している。
【００２２】

BACKGROUND OF THE INVENTION
The present invention relates to a general combine that threshes rice, wheat, beans, and other grains harvested by a harvesting unit through a feeder house and then threshs the whole.
[0002]
[Problems to be solved by the invention]
Before and after the handling room, make the axis perpendicular to the traveling direction of the aircraft In the threshing structure in which two screw-type handling cylinders are arranged side by side, in the means for performing threshing while the grain is being fed in the axial direction of the handling cylinder by a screw, the first at the transverse feed end of the first handling cylinder. 2 When transferring grain to the feed end of the barrel, the transverse direction and the direction of inheritance are perpendicular to each other, making it difficult to smoothly transfer the grain and causing clogging of the grain at this joint. There is an inconvenience. For this reason, there is a means for promoting grain inheritance by providing a communication rod between the lateral feed end of the first barrel at the bottom of the chamber and the lateral feed start end of the second barrel. And when it arrange | positions outside the handling chamber of a 2nd handling cylinder, there exists a problem that the threshing width expands that much.
[0003]
Further, when the communication rods are integrally provided by wrapping the receiving rods of the first and second handling cylinders, there is an inconvenience that it is necessary to remove even the communication rods when removing the receiving rods. .
[0004]
Further, even when it is necessary to adjust the gap between the handling cylinder and the receiving net due to welding distortion or variation of the net frame, there is a problem that it cannot be easily performed by adjusting the attachment position of the net frame.
[0005]
Furthermore, when the waste blade provided at the end of the lateral feed of the first and second handling cylinders is movable so that it tilts against the torsion coil spring, it is possible to prevent deformation of the waste blade when the grain is clogged, etc. There was an inconvenience that it was not possible to secure a sufficient output of grain.
[0006]
[Means for Solving the Problems]
Therefore, the present invention Before and after the handling room, make the axis perpendicular to the traveling direction of the aircraft In a normal combine having two screw-type first and second handling cylinders, the first and second handling cylinders are obtained by dividing the front and rear ends of a communication rod communicating between the handling chambers of the first and second handling cylinders. The guide rod is integrally provided on the mesh frame of the receiving net of the first and second handling cylinders, and the receiving net and the net frame can be easily removed while leaving the communication rod in the handling chamber. This makes it possible to improve the efficiency of maintenance and inspection work with the receiving network removed.
[0007]
Moreover, a communicating rod is arrange | positioned in the width of the chamber which installs a 1st and 2nd handling cylinder, and a communicating rod is integrated in a threshing part compactly, and size reduction of a combine machine body is achieved.
[0008]
Furthermore, even in a combined structure in which a plurality of scissors are connected by providing a drop in the order of the guide scissors of the first handling cylinder, the communication scissors, and the guide scissors of the second handling cylinder, the top of each scissor is not disturbed. By smoothly moving the heel, it is possible to improve the inheritance of the heel from the first handling cylinder to the second handling cylinder.
[0009]
Furthermore, a step for increasing the lateral width is provided on the side walls in the order of the guide rod of the first handling cylinder, the communication rod of the first handling cylinder, and the guide rod of the second handling cylinder. The hull is smoothly guided without hindering the flow of the hull so as to improve the hull inheritance.
[0010]
In addition, a frame guide rail that supports the net frame is provided on the threshing side plate, and the guide rail is provided so as to be movable and adjustable in the center radial direction of the handle cylinder. Even when it is necessary to adjust the gap, the gap is easily maintained appropriately by adjusting the movement of the guide rail, and the threshing accuracy is stably maintained.
[0011]
Further, a discharge vane having a certain clearance angle is fixed to the outer periphery of the feed end of the first barrel corresponding to the communication rod, and a discharge blade having a clearance angle of 0 is fixed to the outer periphery of the feed end of the second barrel. In this way, the throwing power of the rear hook at the lateral feed end of the first and second handling cylinders is improved, and the transferability to the second handling cylinder and the rejectability from the second handling cylinder are improved. is there.
