〔産業上の利用分野〕
本発明は、刈取機において、植立茎稈を刈取り
対象茎稈と非刈取り対象茎稈とに分けたり、刈取
り対象茎稈の一対の茎稈引起こし経路の一方と他
方とに分けるための分草具に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a reaping machine to divide a planted stem culm into a stem culm to be harvested and a stem culm not to be harvested, or to separate a pair of stems of a stalk culm to be harvested. The present invention relates to a weed cutting tool for dividing a culm raising path into one side and the other side.

Conventionally, as a weeding tool for a reaper,
- As shown in Publication No. 61714, the weeding tool is attached so that it can be switched between a usage position where the tip faces forward of the aircraft and a storage position where the tip enters the stem culm introduction path and faces sideways.

たもの。(b) For example, as shown in Japanese Utility Model Application Publication No. 50-122520, the tip of the weeding tool faces forward of the aircraft by rotating around the axis of the forward-upward tilted position of the weeding tool at its intermediate position. It is installed so that it can be switched freely between the usage position and the storage position with the tip facing upwards and backwards.

を前記格納姿勢に切換え、分草具に対するカバー
やバンパーを用いなくとも、分草具の比較的鋭い
先端の前向き露出を避けた安全な状態を確保でき
るようにしたものがあつた。It is well known that when driving on the road, etc., the weeding tool can be switched to the retracted position, and the relatively sharp tip of the weeding tool can be safely avoided from being exposed forward without using a cover or bumper for the weeding tool. There was something that made it possible to ensure a safe state.

However, in the conventional structure (a) above,
If you forget to change the weeding tool to the working position when you start working after switching the weeding tool to the stored position, the weeding tool in the retracted position will enter the stem culm introduction path sideways. The weeding tools sometimes caused problems in pushing down the planted stem culms.

する等の不具合があつた。 On the other hand, with the method described in (b) above, although it is possible to prevent the tip of the weeding tool from entering the stem culm introduction path, when the weeding tool is in its retracted position, the widening part of the weeding tool reaches the stem culm. Since the plant is in an overhanging position at the base of the plant, there have been problems such as the stem culm coming into contact with the widening part of the weeding tool and being knocked down if the user forgets to set it in the usage position.

を特徴構成とする。[Means for Solving the Problems] In order to achieve the above-mentioned object, the weeding tool of the reaper according to the present invention divides the weeding tool that acts on the planted stem culm into two parts into the front and back, and The front end portion of the weeding tool is stored in a working position in which the tip of the weeding tool faces forward of the machine, and in a position where the tip points upward and backward above the weeding tool support frame located on the lateral outside of the stem culm introduction path. The present invention is characterized in that the weeding tool is attached to the rear end portion of the weeding tool so as to be able to freely switch between the posture and the posture by swinging around the horizontal axis.
かかる特徴構成による作用及び効果は次の通り
である。 The functions and effects of this characteristic configuration are as follows.

In other words, by swinging the front end of the weeding tool around the horizontal axis, it can be placed in a retracted position that faces upward and backward, and in this retracted position, the sharp end of the weeding tool does not protrude forward. This prevents the sharp portion from colliding with other objects. In addition, even if you start reaping in the retracted position, the weeding performance will be poor, but the structure is designed to suppress the lateral overhang of the reaped stem culm, which would push down the base of the plant. It is also easy to avoid pushing down.
従つて、単に分草具の前端側部分を横軸芯周り
で揺動操作するだけの簡単な操作で分草具先端部

押し倒すことも回避でき、刈取作業を良好に行う
ことができるに至つた。
Therefore, the simple operation of simply swinging the front end of the weeding tool around the horizontal axis is sufficient to avoid problems such as the tip of the weeding tool coming into contact with other objects. Even if the user forgets to change the posture of the tip during reaping work, it is possible to avoid pressing down the stem culm by improperly contacting the base of the stem culm, and the reaping work can be performed satisfactorily.

Separating the grass on both sides with the weeding tool 2 and introducing it into the stem culm introduction paths 3, 3 on both sides,
Then, the stem culms that have entered the stem culm introduction path 3 are raised by the raising device 4 and harvested by the reaping device 5, and the cut stem culms are conveyed to the rear of the machine by the conveying device 6 and supplied to the starting end of the threshing section 7. The reaping pre-processing section configured as shown in FIG.
A combine harvester is constructed by equipping the front part of a crawler-type traveling machine body with such equipment.

The front end portion 13 is pivotally mounted to swing vertically around a horizontal axis P. When the front end portion 13 is lowered until the base comes into contact with the lower end side of the rear end portion 12, the tip F will face forward of the aircraft, and the surface of the rear end portion will be lower than the rear end portion 12. When it reaches the usage position where it connects to the surface and lifts until the tip side touches the upper end side of the rear end side part 12, the tip F is located above the weeding tool support frame 9 and the machine is in the storage position facing upward and backward. It is configured to be. That is, by changing the posture of only the front end portions 13 of the weeding tools 1 and 2, the tips F are housed inside the body.
