As can be seen in Japanese Patent No. 17, the second cutting blade is installed in the running part,
The cutting edge position is positioned between the mowing section composed of the first cutting blade and the traveling section, and the first and second cutting blades have the same cutting width, and the uncut blade side on the left side in the machine traveling direction. The edge and the edge of the already-cut blade on the right side in the traveling direction of the machine body are aligned with each other.

（実施例） 以下、図面に示す実施例について説明する。(Example) Hereinafter, the Example shown in drawing is described.
先ず、従来の二段刈刃式コンバインから説明する。First, a conventional two-stage cutting blade combine will be described.
穀稈は掻込リール（１）で掻きこまれて刈刃（２）で刈
り取られ、刈り取られた穀稈は掻込オーガ（３）からフ
ィーダーハウス（４）のチェーンコンベア（５）で扱室
（６）に運ばれスクリュー式扱胴（７）で脱穀される。The grain culm is scraped by the scraping reel (1) and cut by the cutting blade (2). The cut grain culm is handled from the scraping auger (3) to the chain conveyor (5) of the feeder house (4). It is carried to (6) and threshed by the screw type handling cylinder (7).
脱穀されたものは受網（８）から回動オーガ（９）上に
落下し、回転するオーガ（９）によりその終端部に向け
移動すると共に藁は排稈口（6a）から排出される。The threshed ones drop from the net (8) onto the rotating auger (9), move toward the terminal end of the rotating auger (9), and the straw is discharged from the outlet (6a).
この搬送過程で穀類と細かい藁屑はオーガ（９）の受樋
部分に張設された受網（10）から下方に落下し、長藁の
み排稈口（11）方向に運ばれる。During this transportation process, grains and fine straw debris fall downward from the net (10) stretched over the gutter of the auger (9), and only the long straws are carried toward the outlet (11).

扱室（６）に還元される。Leakage material containing grains that have fallen from the net (10) is carried in the most gutter direction by the conveyor (12), and the sorting wind from the end of the conveyor (12) is blown by a blower fan (13) such as Karato. Received the grains fell on the first gutter (15) and the second one fell on the second gutter (14),
The grain dropped to the first gutter (15) is carried to the paddy tank (20) via the lifting cylinder (17), and the second one is returned to the handling room (6) by the return conveyor (18).

(24) is the driver's seat.
そして、株元部を刈り倒す第２刈刃は走行部に配置して
ある。And the 2nd cutting blade which cuts down the root part is arrange | positioned at the traveling part.
すなわち、第３図に示すように（25）は走行部の主フレ
ームであり、これに刈刃フレーム（26）の基部が取付け
られており、その位置が脱穀部前面にあたる。That is, as shown in FIG. 3, (25) is the main frame of the running part, to which the base of the cutting blade frame (26) is attached, and its position corresponds to the front of the threshing part.
又、トラックフレーム（27）の左右の継ぎパイプ（28）
には油圧シリンダー（29）が設けられ、 これによって刈刃フレーム（26）を軸（30）を中心とし
て揺動させ刈刃を昇降するようになっている。Also, the left and right joint pipes (28) of the truck frame (27)
A hydraulic cylinder (29) is provided on the blade, and the cutting blade frame (26) is swung about the shaft (30) to move the cutting blade up and down.
そして、軸（30）に取付けられたクランク板（31）の偏
心位置（32）にロッド（33）の取付金具（34）が取付け

5）の他方のアーム（35b）に刈刃（37）の駆動アーム
（36）が枢支されている。（38）はベルクランク（35）
の枢支部である。Then, the mounting bracket (34) for the rod (33) is mounted at the eccentric position (32) of the crank plate (31) mounted on the shaft (30), and the tip of the rod (33) is located at the bell crank (35).
Pivoted to one arm (35a) of the bell crank (3
The drive arm (36) of the cutting blade (37) is pivotally supported by the other arm (35b) of 5). (38) is the bell crank (35)
Is the pivotal branch of.
以上のような構造からクランク板（31）が図示しない駆
動装置を介して駆動されるとロッド（33）が上下動し、
ベルクランク（35）を揺動させるので刈刃（37）の移動
刃が固定刃に対して左右動するものである。With the above structure, when the crank plate (31) is driven by a driving device (not shown), the rod (33) moves up and down,
Since the bell crank (35) is swung, the moving blade of the cutting blade (37) moves left and right with respect to the fixed blade.
以上の如く走行部に取付けられた第２の刈刃（37）を具
えているので走行部と共に昇降し、地面との相対位置が
刈取部の刈高さが変わっても常時一定に株元を刈り倒し
て行くことができるのである。Since it has the second cutting blade (37) attached to the running part as described above, it moves up and down together with the running part, and the relative position with respect to the ground is always constant even if the cutting height of the cutting part changes. You can cut down and go.
本発明は以上のようなコンバインにおいて、第４図に示
す如く後方刈刃（37）の機体進行方向左側における未刈
側側縁（ａ）が前方刈刃（２）の機体進行方向左側にお
ける未刈側側縁（ｂ）よりもｘだけ機体内方にずらせて
設けたものである。In the combine as described above, according to the present invention, as shown in FIG. 4, the uncut side edge (a) of the rear cutting blade (37) on the left side of the machine moving direction is not formed on the left side of the front cutting blade (2) on the left side of the machine moving direction. It is provided so as to be shifted toward the inside of the body by x from the side edge (b) on the cutting side.
そして、図示のものでは中割作業時に後方刈刃によって
右側穀稈を刈倒して圃場に散逸させないよう右側側縁
（ｃ）（ｄ）は前後一致させてある。In the illustrated case, the right side edges (c) and (d) are aligned front and back so that the right cutting culms are not cut down by the rear cutting blade and scattered to the field during the splitting operation.
以上の如く構成してあると、後方刈刃の巾（ｙ）内の穀
稈は株元がきれいに刈揃えられる。With the above-described structure, the grain culms within the width (y) of the rear cutting blade can be neatly trimmed at the roots.
又、巾ｘに位置する穀稈は高刈りのままにあるので、第
４図の如く次工程で既刈側にｘだけオーバーラップさせ
て刈れば巾ｘ内の穀稈の株元も刈揃えられ、穀稈が圃場
に散逸することもない。Moreover, since the grain culm located in the width x is still in high cutting, if the grain is overlapped by x in the next step as shown in Fig. 4, the grain culms within the width x are also trimmed. Therefore, the culms are not scattered in the field.
したがって、刈取作業能率は低下しない。Therefore, the reaping work efficiency does not decrease.
なお、本発明のものは図示のような全量投入タイプのコ
ンバインのみならず、自脱型のコンバインにも適用可能
である。The present invention can be applied not only to the total amount input type combine as shown in the drawing but also to a self-removing type combine.
