している。(Prior Art) Conventionally, in a two-stage cutting blade type combine having a first cutting blade for cutting grain and a second cutting blade for stock alignment, Japanese Patent Application Laid-Open No. 60-2442
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.

In the case where most of them are wrapped around each other, the uncut side edge of the rear cutting blade on the left side of the machine moving direction is provided so as to be displaced toward the inside of the machine more than the uncut side edge of the front cutting blade on the left side of the machine moving direction. At the same time, the already-cut side edge of the rear cutting blade on the right side in the direction of travel of the machine body extends outward of the machine body than that of the front cutting blade.

とはない。(Effects of the Invention) According to this technical means, the uncut side extension of the rear cutting blade on the left side in the machine traveling direction is provided so as to be shifted toward the inside of the machine from that of the front cutting blade. Even if the machine is turned to the uncut side for alignment, the rear cutting blade does not cut down the uncut side culm on the left side of the machine direction and disperse it to the field.
又、後方刈刃の機体進行方向右側における既刈側側縁は
前方刈刃のそれよりも機体外方に延設してあるので次工
程の刈取の際株元が刈揃えられ、刈取工程に無駄がなく
作業能率をアップできる。In addition, the already-cut side edge of the rear cutting blade on the right side in the machine traveling direction is extended outward of the machine rather than that of the front cutting blade, so the stocks are cut and aligned during the next step of cutting. You can improve work efficiency without waste.
（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

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）

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, which allows the cutting blade frame (26) to swing 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

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.

体外方にx2だけ延設したものである。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 by being shifted toward the inside of the machine by x 1 from the cutting side edge (b), and the already-cut side edge (c) on the right side of the rear cutting blade (27) in the machine traveling direction is the front cutting blade (2). It is extended by x 2 outside the fuselage.
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（x1）に位置する穀稈は高刈りのままにあるが、
次工程刈取時に後方刈刃（27）の（x1）延長部分が位置
することとなり、これによって株元が刈揃えられること
になる。Also, although the grain culm located in the width (x 1 ) is still high-cut,
The (x 1 ) extension of the rear cutting blade (27) will be located at the time of cutting in the next step, and the stocks will be cut and aligned accordingly.
なお、このとき前方刈刃（２）は前工程とラップさせな
くてよいので刈取工程に無駄がない。At this time, since the front cutting blade (2) does not need to be wrapped with the previous step, the cutting step is not wasted.
又、右側デバイダ（23）をx2の巾を覆うように第２図
（23′）の如く斜めに突出させておくと、中割作業時に

逸させることがない。In addition, if the right divider (23) is made to project diagonally as shown in Fig. 2 (23 ') so as to cover the width of x 2 , it is possible to perform splitting work.
The grain culm located at the x 2 part will not be shattered by the rear cutting blade and scattered to the field.
更に又、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。Furthermore, the present invention can be applied not only to the total amount input type combine as shown, but also to a self-removing type combine.
