b. The operation of the horizontal sensor 51 is delayed by a certain period of time in the above state.

The operation of the C0 horizontal sensor 51 becomes slow in the above state.

Since the structure is as follows, the reaping section 4 can be operated at high speed,
Even when the traveling speed becomes high and the reaping section 4 vibrates, it can operate properly and prevent erroneous operation in which the reaping section 4 rolls even though the reaping section 4 is not inclined.

(Effects) Conventionally, it has been known to automatically roll the reaping section of a combine harvester using a horizontal sensor provided in the reaping section.

Since the above-mentioned known device is equipped with a "horizontal sensor" in the raising case of the reaping section, when the machine traveling speed increases or the reaping speed of the reaping section increases, the vibration of the clipper of the reaping section and the raising There was a problem in which the horizontal sensor malfunctioned due to vibrations in the case, causing the mouth/rings to not operate properly.In addition, the reaping part rolled more than necessary, causing workers to feel uneasy, making it difficult to work with the combine. There was also the problem of high fatigue.

However, in the present invention, the reaping section 4 of the combine is automatically rolled by a horizontal sensor 51, and the horizontal sensor 51 is configured to automatically roll the reaping section 4 of the combine when the traveling speed of the machine increases or the reaping speed of the reaping section 4 increases. This is because the reaping section rolling device in the combine has been adapted to delay the rolling timing, reduce the sensitivity of the sensor, or slow down the operation of the reaping section 4 accordingly. Even if the reaping section 4 vibrates at high speed, it can operate properly and prevent erroneous operation of rolling the reaping section 4 even though the reaping section 4 is not inclined.

Currently, in cold and high temperatures, the expansion and contraction speed of the cylinder changes as the oil temperature changes, so in order to keep this constant, a sensitivity yt node switch is incorporated. By combining this sensitivity adjustment switch with a reaping speed switch, the present invention can be easily implemented.
