DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for continuously cutting and threshing grain culms and extracting grains from a threshing unit into a grain tank.

[0002]

Conventionally, a grain discharge auger is provided rotatably with respect to the machine body, and a turning position detecting means for detecting a turning position of the discharge auger with respect to the machine body is provided. A control means for auger movement for automatically moving the discharge auger to the storage position based on the detection result of the turning position detection means, an auger clutch for performing an on / off operation of driving the discharge auger, and the control means In response to this, there is a technique in which manual operation means for instructing rotation of the discharge auger is provided.

[0003] The above-mentioned prior art has a problem that even when the discharge auger is in a region where the kernel cannot be discharged, such as the storage position of the machine body, the kernel is discharged by the engagement of the auger clutch. Further, when the discharge auger is automatically moved to the storage position of the machine body, there is a problem that the discharge auger turns while discharging the grains due to the engagement of the auger clutch. In addition, after the power supply voltage is no longer in the energized state required for automatic control, restarting the power supply restarts the automatic control without resetting, for example, the discharge auger turns and the grains are discharged. There is a malfunction such as malfunction.

[0004]

According to the present invention, a grain discharge auger is provided so as to be capable of turning with respect to the machine body, and a turning position detecting means for detecting a turning position of the discharge auger with respect to the machine body is provided. An auger movement control means for automatically moving the discharge auger to the storage position in accordance with a command from the command means is provided, an auger clutch for performing an on / off operation of driving the discharge auger is provided, and the discharge auger is provided to the control means. In the combine provided with manual operation means for instructing rotation of the auger, when the discharge auger is located in the storage position or in a non-dischargeable area near the storage position, the clutch operation means is operated so as to operate the auger clutch in a disengaged state. By detecting that the discharge auger reaches the vicinity of the storage position and is located in the area where the grain cannot be discharged, Is kept off the auger clutch are those obtained without the problem of grain is discharged by the entry of the auger clutch, for example, grain from the discharge auger toward the machine body can be prevented from scattering.

Also, a clutch operating means for automatically operating the auger clutch in a disengaged state based on a command of the automatic turning command means is provided. By automatically moving the discharge auger in the direction of the storage position of the machine body, Disconnecting the auger clutch can prevent the grains from being discharged from the discharge auger, and can eliminate the problem of discharging the grains while the discharge auger moves to the storage position of the machine body, for example.

Further, the control state is reset by detecting an abnormal decrease in the automatic control voltage, stopping the automatic control of the control means, turning off the power switch of the control means and turning it on again. For example, the automatic control of the control means is stopped even if the disconnection state (power off state) is reached, and the control state is reset by restarting the power switch, so that the control means is self-held using, for example, a relay. The control operation is released, and a malfunction in which a malfunction such as turning of the discharge auger or discharge of grain is performed by turning on the power switch can be eliminated.

In the combine provided with manual operation means (50) and (51) for instructing the turn of 8), when the discharge auger (18) is located in the storage position or in the non-dischargeable area near the storage position, the auger clutch (41) is used. ) Is configured to operate the clutch in a disengaged state, and it is detected that the discharge auger (18) has reached the vicinity of the storage position and is located in the area where the grain cannot be discharged. As a result, the auger clutch (41) is maintained in the disengaged state,
It is possible to eliminate the problem that the grains are discharged by the insertion of the auger clutch (41). For example, it is possible to prevent the grains from scattering from the discharge auger (18) toward the machine body.

A clutch operating means (42) for automatically operating the auger clutch (41) in a disengaged state on the basis of a command from the automatic turning command means (46) is provided. By automatically moving (18), it is possible to prevent the kernel from being discharged from the discharge auger (18) due to the disengagement of the auger clutch (41). For example, the discharge auger (18) is moved to the storage position of the machine body. However, it is possible to eliminate the problem of discharging grains.

The control state is reset by detecting the abnormal decrease of the automatic control voltage, stopping the automatic control of the control means (58), turning off the power switch of the control means (58) and turning it on again. The automatic control of the control means (58) is stopped even if a disconnection state (power-off state) occurs, and the control state is reset by restarting the power switch.
For example, the control operation that was held by using a relay or the like is released, and it is possible to eliminate a malfunction in which a malfunction such as turning of the discharge auger (18) or discharging of grains is performed by turning on a power switch. .
