【発明の詳細な説明】 本発明は、バインダー、コンバイン等の刈取収穫機に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to reaping and harvesting machines such as binders and combines.

この種の刈取収穫機では、自動化を推進させるべく、例

茎稈がなくなる一行程終端等において、自動的に機体を
停止させることが行なわれている。In order to promote automation, this type of reaping/harvesting machine is provided with, for example, a traveling direction regulating guide that is guided in contact with the planted stem culms and follows the machine body along the stem culm row.
An automatic travel stop operation mechanism is provided that automatically stops the aircraft traveling in conjunction with the detection of the presence or absence of a planted stalk culm by the plant culm presence/absence detection mechanism.
The machine is not automatically advanced along the row of planted stems, but is automatically stopped at the end of one stroke when the planted stems run out.

また、上記自動刈取収穫作業は、主として、茎稈が列条

は人為的に行なわれることになる。In addition, the automatic reaping and harvesting work described above is mainly performed when the stem culms are planted in rows in an orderly manner, and when the stem culms are planted in an irregular manner, the automatic reaping and harvesting work is performed when the stem culms are planted in an irregular manner. The work is difficult, and steering and stopping of the aircraft must be done manually.

って機体の走行操作が思うようにいかない欠点があった
。Conventionally, in order to switch the automatic stop operation mechanism and the traveling direction restriction guide into an operating state and a non-operating state, respectively,
This was done separately and independently, but in this case, not only was the operation cumbersome because it was done separately, but for example, if the stem culm was misaligned, only the automatic stop operation mechanism could be deactivated. If one forgets to switch the traveling direction regulating guide to a non-operating state, the traveling direction regulating guide may hit the planted stem culm, making it difficult to operate the machine as expected.

にある。The reaping and harvesting machine of the present invention is characterized by an umbrella-shaped advancing direction regulating mechanism in the front part of the machine body that contacts the base of the stem culm and causes the machine body to follow the stem culm row; a detection mechanism for detecting the presence or absence of a planted stem culm on one side, a running latch for turning on and off the traveling device of the aircraft body, and an operation lever linked to the traveling direction regulating mechanism and the presence/absence detection mechanism of a planted stem culm; In the reaping/harvesting machine, the operating lever can be operated around the pivot axis of the operating lever and in a direction perpendicular thereto, and the operating lever can be operated unstable around the pivot axis around the switching fulcrum. A first switch which is configured to be switchable and which transmits the movement of the operating lever to the moving latch is attached to the pivot shaft portions on both sides of the operating lever.
When the engaging piece and the operating lever are operated toward the latch entry side, the umbrella-shaped advancing direction regulating mechanism is opened, and when the operating lever is operated toward the latch disengagement side, the umbrella-shaped advancing direction is opened. A second engaging piece for closing the direction regulating mechanism is provided, and the operation lever is moved between the first engaging piece and the first engaging piece by operating the operating lever in the direction of the thin pivot axis of the operating lever. The latch is configured to be selectively engageable with both the joint piece and the second engaging piece, and the second engaging piece has a latch that runs based on the detection of the presence of a stem culm by the planted stem culm presence/absence detection mechanism. While maintaining the position of the operation lever in the closed state and in the state where the latch is biased toward the closed side, the latch is moved based on the detection of the absence of a stem culm by the planted stem culm presence/absence detection mechanism. An engaging protrusion of the locking mechanism is provided for releasing the holding position of the operating lever which is in the latch state and is biased toward the running latch-off side.

すなわち、走行自動停止操作機構と進行方向規制機構と

きるから、両者を夫々別個に切換え操作するに較べて、
操作が簡単になるとともに両者を一挙に作動状態と非作
動状態とに切換え得る故に、不測な操作ミス等を起す虞
れもなくなりもって、扱い易く、安全、良好な刈取作業
を行ない得る刈取収穫機を得るに至ったのである。That is, since the automatic traveling stop operation mechanism and the traveling direction regulating mechanism can be simultaneously switched between the operating state and the non-operating state, compared to switching the two separately,
To provide a reaping harvester that is easy to operate and can perform safe and good reaping work, eliminating the risk of unexpected operational errors because both can be switched between the operating state and the non-operating state at once. I was able to obtain this.

。In order to control the machine to follow along the row of planted stem culms, a guide tool is used to control the direction of movement of the machine by touching the base of the planted stem culm and swinging the machine directly. For example, by providing a contact sensor that contacts the planted stem culm and detecting the displacement of the swing angle of the contact sensor, the signal is transmitted to the electromagnetic clutch of the traveling device to control the aircraft. This has the advantage that the steering control device can be constructed from a simple and inexpensive device compared to a case where the steering direction is controlled electrically.
