つて的確な稈長検出を行うことができる。 With this configuration, the present invention provides the following effects. In other words, the sensing element hangs down from above and comes into contact with the ears of the grain being transported, so it is sensitively activated by a small pressing force from the ears. It is extremely rare for the sensor to malfunction, and accurate culm length detection can be performed over a long period of time even under adverse working conditions.

When the machine moves forward and starts reaping and threshing work, the standing grain culms in the field are divided into the inside and outside of the machine body by the weeding device 4, and the grain culms located inside the machine body are separated by the grain culm lifting device. 5, the grain culm is raised to an upright state, and the raised grain culm is cut off at its base by a reaping device 3, and is engaged with a grain culm conveying device 6 to gradually change from an upright state to a horizontal state. The grains are transported backward while being positioned and fed into the automatic grain feed chain 8. Then, while being subjected to a threshing process, the grain culm is conveyed from the grain culm supply port side to the grain culm discharge port side by the grain culm automatic feeding chain 8 and discharged outside the machine.
このような場合において、脱穀装置７に供給さ
れる穀稈の長さは種々雑多であり、それに応じて
扱ぎ深さを調節しなければ扱ぎ残りを生じたり、
或は、脱穀部に多量の藁屑を発生して選別処理を
悪化ならしめる。 In such cases, the lengths of the grain culms supplied to the threshing device 7 vary widely, and if the handling depth is not adjusted accordingly, unhandled grain may be left.
Alternatively, a large amount of straw waste is generated in the threshing section, which impairs the sorting process.
このような欠陥を克服するためには、該感知体
１０の感知作用によつて稈長を検出し、脱穀機に
対する穀稈の扱ぎ深さを自動的に一定にしなけれ
ばならない。 In order to overcome this drawback, the culm length must be detected by the sensing action of the sensor 10, and the depth of handling of the grain culm with respect to the threshing machine must be automatically made constant.

用する。 Therefore, when the grain culm harvested by the reaping device 3 passes under the sensing body 10, if the grain culm is tall, it will hit the sensing body 10.
by rotating the hydraulic cylinder 1 from the hydraulic mechanism 14.
5, the hydraulic cylinder 15 is extended, and the front end of the rotating frame 12 is lifted upward about the shaft 13. When the front end of the rotating frame 12 moves upward, the reaping device 3 and grain culm conveying device 6 attached to it move upward, and therefore, the standing grain culm is cut at a high position.
In the end, even tall grain culms are cut to a certain length and transported, so that there is no need for heavy handling. In the case of short grain culms, the effect is opposite to the above.
