Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a combine harvester equipped with a culm handling depth adjustment device, more specifically, a handling depth adjustment device, and the adjustment device is connected to a culm conveyance detection sensor, a long and short culm detection sensor. The present invention relates to a combine harvester that is automatically controlled by a sensor (forming an automatic control circuit) and in which the control circuit is provided with an automatic switch for switching the circuit to a non-operating state.

Generally, this type of combine harvester includes a reaping section and a threshing section,
A shell culm conveying device is provided between the reaping section and the threshing section, and the shell culm harvested by the reaping section is conveyed and supplied to the threshing section by the conveying device, and is threshed in the threshing section. There is.

The handling depth adjusting device is interlocked and connected to the conveying device, and the adjusting device enables the conveying device to swing toward and away from the foot chain of the threshing section. The handling depth of the shell culm by the threshing section can be adjusted by changing and adjusting the delivery position of the shell culm to the foot chewer.

Further, the adjustment device is connected to the automatic control circuit mentioned above, and the circuit is operated by an automatic switch of this control circuit to automatically control the adjustment of the handling depth of grain culms by the conveyance device. A manual switch for operating the conveying device to the deep handling side and the cross-cutting side is connected to the adjustment device, and the conveying device can also be operated manually via this switch.

By the way, when the combine harvester is running for work, the automatic control circuit may be opened by an automatic switch, and the culm conveying device may be adjusted to be moved to the deepest handling side or the shallowest handling side using a manual switch to perform the work. For example, when threshing headland husks in a careless manner, or when moving a combine harvester between fields, move the conveyor device to the deepest handling side inside the machine. However, after moving the conveyance device to the deepest or shallowest handling side and performing the specified work, he forgot to close the automatic control circuit and started the reaping and threshing work. Then, the conveying device remains moved to the deepest or shallowest handling side, resulting in unhandled grain culms and clogging of the husk in the threshing section.

The present invention was developed in view of the above-mentioned problem. After moving the shell culm conveying device to the deepest or shallowest handling side and performing a prescribed work, the user forgets to close the automatic control circuit. , When reaping and threshing work is performed with the circuit turned off, an alarm should be issued for a certain period of time to notify the operator of an abnormality. This is to prevent clogging.

More specifically, an operating circuit is formed that continuously outputs an output for a certain period of time in response to human power, and when the automatic control circuit is switched to a non-operating state by the automatic switch, the circuit is connected to the conveyance detection sensor and the long and short culms. A detection sensor is connected to the output side of both sensors to be activated by both outputs, and this activation circuit is connected to an alarm device to operate the alarm device for a certain period of time, and an alarm is output from the activation circuit. Each time one of the outputs from the two sensors to the operating circuit is cut off according to the output to the device.

As a level, each of the above AND circuits (23), (23)
This is to stop the output from the alarm and stop the operation of the alarm device (26).

In short, the R-8-F-P circuit (27) and the switching circuit (29) are connected from the operating circuit (21) to the alarm device (2).
6) and when the alarm device (26) is activated, the input to the activation circuit (21) is cut off after a certain period of time rather than allowing the alarm device (26) to continue operating. This is used to stop the alarm device (26).

This is because with the automatic control circuit (9) open, the handling depth adjustment device (8) is manually operated to move and adjust the culm conveyance device (5) to the shallowest or deepest rear side. If the operator forgets to close the control circuit (9) after performing the work and continues the combine harvesting/threshing work, the operator can activate the warning device (26) for a short time. You will notice it right away, and when the combine harvester reaps and threshes, there are cases where the harvesting and threshing is done manually over a very short or very long distance, and if the alarm device (26) continues to operate in this case, the noise will be loud. Rather, it causes inconvenience, and therefore, the R-8-F.7 circuit (27) and the switching circuit (29) are used to operate the alarm device (26) for a certain period of time.

A switching circuit (29) connected to the R-8-7-IP circuit (27) may be provided on the input side of the actuation circuit (21).

The combine harvester of the present invention is configured as described above, and during reaping and threshing work, the handling depth adjustment device (8) of the culm conveying device (5) is controlled by the automatic control circuit (9) or the manual switch (1).
0a) and (10b), and this transport device (5
) is swung toward and away from the foot chain (61) of the threshing section (3), thereby adjusting the depth of handling of the husk by the threshing section (6).

However, when the combine harvester is used to harvest and thresh, when threshing the headland husks or when moving between fields, the automatic control 4 circuit (9) can be switched to the automatic switch (18). (18) in the open state, the manual switch (10a), (101
This is done by moving the shell culm conveying device (5) to the deepest point or the most planing side using the culm transfer device (5). forget,
When the reaping and threshing work starts, the operating circuit (21) connected to the control circuit (9) is activated, and the alarm device (26) issues an alarm to notify the operator. , it only operates for a certain period of time, so even if the alarm device (26) is activated, it will not be a hindrance when reaping and threshing ultra-short or ultra-long culms while manually adjusting the handling depth.

As explained above, in the combine harvester of the present invention, with the automatic control circuit of the handling depth adjustment device open, the culm conveying device is moved to the deepest position or the most boarding side, and after performing a predetermined work, When the operator forgot to close the control circuit and performed reaping and threshing work with the circuit turned off, the alarm device was designed to issue an alarm for a certain period of time, so this alarm caused the operator to operate the machine in an abnormal state. The operator immediately closes the automatic control circuit and
It is possible to return to the normal state, and it is possible to prevent unhandled husks and clogging of grain culms due to continued operation in an abnormal state.

In addition, since the alarm device is only activated for a certain period of time, even if the alarm device is activated during normal combine harvester operation, when harvesting and threshing is done while manually adjusting the handling depth over very short or long distances, The alarm from the alarm device does not become a noise or become a nuisance.
