りする問題があつた。 Conventionally, in this type of combine harvester, long and short culm detection sensors are installed, for example, at the entrance of the handling chamber of the threshing device, but this handling chamber entrance corresponds to the position where grain culms are transferred from the vertical conveyance device to the feed chain. in,
Grain culm stagnation and grain culm tips are easily transported,
When the tip of a grain culm gets entangled with the detection sensor, for example, when the tip of a grain culm gets entangled with the long culm detection sensor, a long culm detection signal is continuously output to the handling depth adjustment device. If the handling depth adjustment device is adjusted to the shallow handling side more than necessary, causing grain culms to be left unhandled due to shallow handling, or if the tip of the grain culm becomes entangled with the short culm detection sensor, the handling depth adjustment device In order to continuously output short culm detection signals, there was a problem that the handling depth adjustment device was moved to the deeper handling side than necessary, resulting in an increase in cut ears due to deep handling. .

During grain culm reaping and threshing, the solenoids SOL 1 and SOL 2 are driven and controlled by the manual switches SW 2 and SW 3 or detection signals from the long and short culm detection sensors 8 and 9, and based on this, the handling depth adjustment device 5 The handling depth of the grain culm is adjusted to the appropriate condition by adjusting and moving the grain culm.
For example, if the manual switch SW 2 is operated with the key switch SW turned on, the solenoid SOL 1 is connected to the power supply E, the solenoid SOL 1 is energized, and the handling depth adjustment device 5 is adjusted and moved to the shallow handling side. let me,
If you operate manual switch SW 3 , the solenoid
SOL 2 is connected to the power source E, and the solenoid SOL 2 is energized to adjust and move the handling depth adjusting device 5 to the deep handling side. In addition, if the key switch SW and automatic switch SW 3 are turned on, the handling depth of grain culms is automatically adjusted. The sensor 10 operates and turns on its normally open contact SW L -a, and the short culm detection sensor 9 comes into contact with the grain culm, turning on its normally open contact SW M -a and turns on its normally closed contact SW M -. b is turned off, and the long culm detection sensor 8
did not come into contact with the grain culm, its normally open contact SW H -a remained off, no output was made to each solenoid SOL 1 and SOL 2 , and the handling depth adjustment device 5 stopped at the proper position. It remains as it is. When the long culm is transported and supplied in such a state, the detection sensor 8 comes into contact with the long culm, turns on its normally open contact SW H -a, and outputs a long culm detection signal to the solenoid SOL 1. When the handling depth adjustment device 5 is adjusted to the shallow handling side and the short culm is transported and supplied, the short culm no longer comes into contact with the detection sensor 9, and its normally closed contact SW M -
b is turned back on, a short culm detection signal is output to the solenoid SOL 2 , and the handling depth adjustment device 5 is adjusted and moved to the deep handling side.

Long and short culm detection signals are output to SOL 1 and SOL 2. In such a case, the handling depth adjusting device 5 is used to operate the limiters 11 and 12, and their respective normally closed contacts LS 1 -b, LS 2 -b is turned off, and the long and short culm detection signal solenoid SOL 1 ,
This cuts off the output to SOL 2 .

の接続回路を閉成して、警報装置１３を作動し、
操縦者に警報を発するのである。 If the tip of the grain culm gets entangled with the detection sensors 8 and 9 in this way, the grain culm will be erroneously detected.
For example, when the tip of a grain culm gets entangled with the long culm detection sensor 8, its normally open contact SW H -a turns on and outputs the same detection signal to the solenoid SOL 1 as when detecting a long culm. In this case, the switching circuit 14 is turned on based on the output of the detection signal to the solenoid SOL 1 , and the connection circuit to the power supply E of the alarm device 13 is closed, and the alarm device 13 is activated.
It issues a warning to the pilot.

る。 That is, when the detection signal is output to the solenoid SOL 1 , this detection signal is output to each input terminal of the AND gate 15. , the other input terminal is outputted via a second delay 19, and this first delay 17 causes the output to be output to the other input terminal only when the output to the solenoid SOL 1 continues for a certain period of time or more. An output is made from the gate 15 to the switching circuit 14, and the alarm device 13 is activated.
従つて長稈検出時と、検出センサー８への穀稈
穂先部の絡み付きによる穀稈の誤検出時とが同一
の検出信号をソレノイドSOL1に出力するも、こ
の誤検出時にのみ警報が行なわれ、長稈検出時に
警報を発するようなことがない。 Therefore, even though the same detection signal is output to solenoid SOL 1 when a long culm is detected and when a grain culm is erroneously detected due to entanglement of the grain culm tip to the detection sensor 8, an alarm is issued only when this erroneous detection occurs. , no alarm is issued when long culms are detected.
また前記の如く第２デイレー１９を介装するこ
とにより、リミツター１１の作動後一定時間を置
いて前記アンドゲート１５への出力がなくなり、
所謂警報装置１３の作動が停止するのである。 Furthermore, by interposing the second delay 19 as described above, the output to the AND gate 15 disappears after a certain period of time after the limiter 11 is activated.
The so-called alarm device 13 stops operating.
従つて極長稈の脱穀時、長稈検出信号が継続し
てソレノイドSOL1に出力されるも、この脱穀中
警報装置１３の作動が継続するようなことがな
い。 Therefore, even though the long culm detection signal is continuously output to the solenoid SOL 1 during threshing of extremely long culms, the operation of the alarm device 13 during threshing does not continue.
尚短稈検出センサー９に穀稈の穂先部が絡み付
いた場合も、前記と同様の動作を行なつて、警報
装置１３の作動とその停止とが行なわれるもので
ある。 Furthermore, even when the tip of the grain culm becomes entangled with the short culm detection sensor 9, the same operation as described above is performed to activate and stop the alarm device 13.

が生じる。 The delay time of the first delays 17 and 18 may be set as long as the amount of movement of the handling depth adjusting device 5 between the movement limit positions, that is, the time required to move 1/2 of the total stroke. That is, when a long culm or a short culm is conveyed and supplied from a state in which a grain culm of an appropriate length is being conveyed and fed and the handling depth adjustment device 5 moves, its movable amount is 1/2 of the total stroke. During normal threshing, the time required for the handling depth adjustment device 5 to move 1/2 of its total stroke may be set. However, if the change in grain culm length is large, it is necessary to set the time required for the handling depth adjusting device 5 to move its entire stroke. If this set time is short, there will be a problem that an alarm will be issued when a long culm is detected.
また前記第２デイレー１９，２０の遅延時間設

る。 As explained above, the combine harvester according to the present invention is
If the tip of a grain culm gets entangled with the long or short culm detection sensor, causing false detection of the grain culm, and if the detection signal continues to be output for a certain period of time,
Since the alarm device is activated to issue an alarm only when a false detection occurs, it is possible to eliminate false detection of grain culms and an increase in the number of cut ears. Since the alarm device is deactivated and the alarm is stopped after a certain period of time after the activation of the alarm device, when threshing an extremely long culm or an extremely short culm, This eliminates the problem of the limiter operating continuously until the culm is completely threshed, and the alarm device does not stop operating immediately after the limiter is activated, but instead stops after a certain period of time. It is possible to know whether a very long culm or a very short culm is being threshed continuously, and if the grain culm changes to a normal length while the alarm device is operating, the warning device can be stopped. It is also possible to confirm that the adjustment to the side of deep treatment has been made correctly.
