以下、この発明の実施例を、図面に基づいて具体的に説明する。
まず、コンバイン15は、図4に示すように、クローラ16,16を装備した走行フレーム1上に、穀稈供給口17を前側に位置させて脱穀装置18を搭載し、その前側に刈取搬送装置19を配置して構成している。そして、刈取搬送装置19は、図面に示すように、基部を走行フレーム1の前部に設けられた懸架台20に、横軸で上下回動自在に懸架し、前方の斜め下方に向けて延長された刈取後フレーム2と、該刈取後フレーム2の先端部に、横方向に向けて配置した伝動ケース3とを一体に連結して略T字型に形成された刈取フレーム4に各装置を支持して構成している。なお、上記刈取フレーム4には、刈取後フレーム2に内装された刈取伝動軸21(図4参照)を介して先端部に連結した前記伝動ケース3内の伝動軸22(図5、及び図6参照)に回転動力が伝動される構成となっている。14は刈取昇降油圧シリンダーを示している。
Embodiments of the present invention will be specifically described below with reference to the drawings.
First, as shown in FIG. 4, the combine 15 is mounted with a threshing device 18 on the traveling frame 1 equipped with the crawlers 16, 16 with the cereal supply port 17 positioned on the front side, and a cutting and conveying device on the front side. 19 is arranged. Then, as shown in the drawing, the cutting and conveying device 19 suspends a base portion on a suspension base 20 provided at the front portion of the traveling frame 1 so as to be pivotable up and down on a horizontal axis, and extends obliquely downward toward the front. Each device is attached to a cutting frame 4 formed in a substantially T shape by integrally connecting a post-cutting frame 2 and a transmission case 3 arranged in the lateral direction to the tip of the post-cutting frame 2. It is configured with support. The cutting frame 4 has a transmission shaft 22 (FIGS. 5 and 6) in the transmission case 3 connected to the tip portion via a cutting transmission shaft 21 (see FIG. 4) housed in the frame 2 after cutting. (See)). Reference numeral 14 denotes a cutting lift hydraulic cylinder.

そして、刈取フレーム4を構成する前記伝動ケース3は、図1に示すように、中央部(刈取後フレーム2が連結された部位)をセンター筒部3aとして、この右側にスペーサ筒23を連結し、更に、このスペーサ筒23の右端に右側筒24を連結して側方に延長した構成とし、前記センター筒部3aの左側には、左側筒25を連結して側方に延長して構成している。そして、上記伝動ケース3は、実施例の場合、刈取後フレーム2を連結したセンター筒部3aより右側が、左側に比較して若干長くなっており、その長い側に、後述する振れ止め装置13が設けられ走行フレーム1の右側前部に連結して走行中の揺れを阻止する構成となっている。   As shown in FIG. 1, the transmission case 3 constituting the cutting frame 4 has a central portion (a portion where the post-cutting frame 2 is connected) as a center tube portion 3a and a spacer tube 23 connected to the right side thereof. Further, a right cylinder 24 is connected to the right end of the spacer cylinder 23 and extended to the side, and a left cylinder 25 is connected to the left side of the center cylinder portion 3a to extend to the side. ing. In the embodiment, the right side of the transmission case 3 is slightly longer than the left side of the center tube portion 3a to which the post-cutting frame 2 is connected. Is provided and is connected to the right front portion of the traveling frame 1 to prevent shaking during traveling.

このように、伝動ケース3は、センター筒部3aの右側にスペーサ筒23を連結して構成するが、このスペーサ筒23の長さを、図5に示した北海道仕様と、図6に示した内地仕様とでは、長さを異にした2型式を選択できる構成にしている。具体的には、実施例の場合、図6に示した内地仕様は、図5に示した北海道仕様に比較してスペーサ筒23を短く構成して、伝動ケース3の全長を短くした構成を採っている。   In this way, the transmission case 3 is configured by connecting the spacer cylinder 23 to the right side of the center cylinder portion 3a. The length of the spacer cylinder 23 is shown in the Hokkaido specification shown in FIG. 5 and FIG. With the inland specifications, it is configured so that two types with different lengths can be selected. Specifically, in the case of the embodiment, the inland specification shown in FIG. 6 adopts a configuration in which the spacer cylinder 23 is configured shorter than the Hokkaido specification shown in FIG. ing.

なお、伝動ケース3の上方に配置して、該伝動ケース3の左側から上方に延長した伝動支持筒26によって支持した各穀稈引起し装置9の伝動装置28は、図5に示すように、北海道仕様と内地仕様との区別をしないで同一の寸法に構成している。   In addition, as shown in FIG. 5, the transmission device 28 of each grain raising device 9 disposed above the transmission case 3 and supported by a transmission support cylinder 26 extending upward from the left side of the transmission case 3, It has the same dimensions without distinguishing between Hokkaido specifications and inland specifications.

このように構成することによって、図6に示した内地仕様のコンバイン15は、北海道仕様に比較して、刈取フレーム4の横幅(伝動ケース3の長さ)がスペーサ筒23を短く構成した分だけ狭くなっているから、トラックへの積み込み時の積載幅が狭くなって有利になった特徴がある。   By configuring in this way, the combine 15 of the inland specification shown in FIG. 6 is equivalent to the configuration in which the width of the cutting frame 4 (the length of the transmission case 3) is shorter than that of the Hokkaido specification. Since it is narrow, it has the advantage that the loading width at the time of loading on the truck is narrowed.

つぎに、刈取装置6は、図1に示すように、前記伝動ケース3の左右両側から前方に向けて支持杆29,29を出して刈取支持フレーム7を連結して支持し、この刈取支持フレーム7の前側に沿わせて左右に2つの往復動刈刃を取り付けて構成している。そして、刈取装置6は、実施例の場合、図1に示すように、伝動ケース3の左右に刈取駆動部12を設けて左右往復運動を伝動できる構成としている。なお、刈取駆動部12は、従来から知られているように、回転運動を左右往復運動に変換して伝動する機構である。   Next, as shown in FIG. 1, the reaping device 6 supports the reaping support frame 7 by connecting the reaping support frames 7 by protruding support rods 29 and 29 from the left and right sides of the transmission case 3 toward the front. 7, two reciprocating cutting blades are attached to the left and right along the front side. In the case of the embodiment, the reaping device 6 is configured such that a reaping drive unit 12 is provided on the left and right sides of the transmission case 3 to transmit the left and right reciprocating motion as shown in FIG. In addition, the cutting drive part 12 is a mechanism which converts a rotational motion into a left-right reciprocating motion and is transmitted as conventionally known.

It is set to the back of 80, and it is set as the structure which extended to the upper side to the height which does not become an obstruction | occlusion of a conveyance grain candy, and supported the said inherited rubber guide board 85 from the lower side by the upper edge.

以上の如き構成であるから、リヤ穂先搬送ラグ81と供給チェン80とは、供給穀稈層を搬送する最終工程で,穀稈と共に送られる藁屑類が入力伝動ケース91の上方に溜まり、入口漏斗84側へ持ち込もうとするが、前記壁板90が脱穀装置18側への移動、落下を止めて、これらを前側の藁屑等流下案内板86上に落下させ、下方の地面側に流下、排出する。この場合、前記壁板90は、既に説明したように、その上縁で前記受継ぎゴムガイド板85を下側から支えた構成としているから、両者の隙間から藁屑や穀粒が後方に抜け落ちることはほとんどなくなり、前側の藁屑等流下案内板86上に落下させることができる。そして、受継ぎゴムガイド板85は、前記壁板90によって下側から支えられ、安定した状態で穀稈を案内し入り口漏斗84に受け継がせることができる。   Because of the above-described configuration, the rear tip transport lug 81 and the supply chain 80 are the final process of transporting the supply cereal layer, and swarf sent together with the cereal accumulates above the input transmission case 91, Although it tries to bring it into the funnel 84 side, the wall plate 90 stops moving and dropping to the threshing device 18 side, and these are dropped on the flow guide plate 86 such as sawdust on the front side, and flow down to the lower ground side. Discharge. In this case, as described above, the wall plate 90 is configured to support the joint rubber guide plate 85 from the lower side with the upper edge thereof, so that sawdust and grains fall backward from the gap between them. There is almost nothing, and it can be dropped on the flow guide plate 86 such as the sawdust on the front side. The inherited rubber guide plate 85 is supported from the lower side by the wall plate 90 and can guide the cereal cake in a stable state and allow the entrance funnel 84 to inherit it.
