Description

  The present invention relates to a combine technique, and more particularly to a technique for operating a discharge auger that discharges grains in a grain tank by wireless communication using a remote control device.

  Conventionally, a combiner that stores grain after threshing selection in a glen tank, conveys the stored grain with an operable discharge auger, and can discharge it to the outside from the discharge port at the tip of the discharge auger. It is publicly known. Among such combiners, there is one that performs a grain discharging operation by operating a discharge auger remotely by wireless communication using a wireless operation device (remote operation device) (for example, see Patent Document 1). ).

  In the technique disclosed in Patent Document 1, a switch for operating a discharge auger and performing a grain discharge operation is provided in a wireless operation device. Thus, the operator operates the switch of the wireless operation device even from a location away from the machine body, so that the operation signal is transmitted from the wireless operation device to the combine control unit, and the operation signal is received. The discharge auger is operated by the control means, and the grain discharge operation can be performed.

  At the time of grain discharge work, after moving the discharge auger to the desired discharge location for discharging the grain, the operator operates the switch for starting grain discharge provided in the wireless operation device, and An operation signal is transmitted from the wireless operation device to the combine control means. If it does so, discharge | emission of the grain will be started from a discharge auger by the control means which received the operation signal. On the other hand, in order to stop the grain discharge operation, the operator operates a switch for stopping grain discharge provided in the wireless operation device, and sends the operation signal from the wireless operation device to the combiner. Transmit to control means. If it does so, discharge of the grain from a discharge auger will be stopped by the control means which received the operation signal.

  Monitoring from the start of grain discharge to the stop of discharge, that is, after the switch for starting grain discharge provided in the wireless operation device is operated until the switch for stopping discharge is operated The operation signal is continuously transmitted from the wireless operation device to the control means. If the control means cannot receive the monitoring signal while discharging the grain from the discharge auger according to the operation of the switch for starting the grain discharge, it is provided in the wireless operation device. Even if it does not receive the operation signal of the switch for stopping the discharge of the kernel, it is configured to stop the discharge of the kernel from the discharge auger.

JP 2006-94728 A

  However, in the technique disclosed in Patent Document 1, during the grain discharging operation by the discharging auger, the control means changes in the usage state of the remote control device (such as the wireless connection is lost), and the monitoring signal Even if the operator cannot temporarily receive the image for a short period of time, the worker uses the remote control device to stop the grain discharge by the discharge auger each time the worker does not intend. The grain discharge had to be resumed. Further, since the monitoring signal is continuously transmitted from the wireless operation device while the discharge auger is operating, the power consumption of the battery of the wireless operation device is remarkable. Therefore, the remaining amount of power of the battery is insufficient, and the monitoring signal is not transmitted from the wireless operation device, so that the control means is relatively likely to stop the operation of the discharge auger.

  The present invention has been made in view of such current problems, and when operating the discharge auger by a remote control device, avoiding unintentionally stopping the operation of the discharge auger as much as possible to improve workability. An object of the present invention is to provide a combine that can suppress a decrease in the amount of heat.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

  That is, in claim 1, an operable discharge auger that discharges the grain in the grain tank to the outside, an operation actuator that operates the discharge auger, a control unit that drives and controls the operation actuator, A remote control unit having an operation start operation unit for starting the operation of the discharge auger by the control unit and transmitting an operation signal of the operation start operation unit to the control unit using wireless communication by power supply from a battery; The remote control device intermittently transmits an operation confirmation signal to the control means when the operation start operation means is operated, and the control means If the confirmation signal is not received beyond the first set time, the actuator for driving is controlled to stop the operation of the discharge auger. That.

  According to a second aspect of the present invention, the remote operation device stops transmission of the operation confirmation signal after the second set time has elapsed after the operation start operation means is operated.

  In claim 3, when the operation of the discharge auger started by the operation of the operation start operation means is completed, the control means transmits an end confirmation signal to the remote operation device. When the end confirmation signal is received, transmission of the operation confirmation signal to the control means is stopped.

  As effects of the present invention, the following effects can be obtained.

In claim 1, the control means receives the operation confirmation signal once after operating the operation start operation means of the remote control device, and then discharges the operation confirmation signal if the operation confirmation signal can be received before the first set time elapses. Stops auger operation. That is, even if the control means cannot continuously receive the operation confirmation signal, if the time when the control cannot be received is within the first set time, the operation of the discharge auger is not stopped.
In addition, since the operation confirmation signal is intermittently transmitted from the remote operation device, the power consumption of the remote operation device can be suppressed and the battery life can be extended. Therefore, during the operation of the discharge auger, the remaining power of the battery of the remote control device is insufficient, and the operation confirmation signal is not transmitted from the remote control device, which may cause the control means to stop the operation of the discharge auger. Can be reduced.
Therefore, when operating the discharge auger with the remote control device, it is possible to avoid as much as possible that the operation of the discharge auger stops unintentionally and to suppress the deterioration of workability.

  According to the second aspect of the present invention, it is possible to prevent the remote control device from continuously transmitting the operation confirmation signal. Therefore, it is possible to extend the battery life by suppressing the power consumption of the remote control device. Therefore, during the operation of the discharge auger, the remaining power of the battery of the remote control device is insufficient, and the operation confirmation signal is not transmitted from the remote control device, which may cause the control means to stop the operation of the discharge auger. Can be reduced.

  According to the third aspect, since the transmission of the operation confirmation signal from the transmission unit of the remote operation device can be stopped when the operation of the discharge auger is finished, the remote operation device continues to transmit the operation confirmation signal in vain. This can be prevented. Therefore, it is possible to extend the battery life by suppressing the power consumption of the remote control device. Therefore, during the operation of the discharge auger, the remaining power of the battery of the remote control device is insufficient, and the operation confirmation signal is not transmitted from the remote control device, which may cause the control means to stop the operation of the discharge auger. Can be reduced.

While the auger raising button 70e or the auger lowering button 70f is being pressed, the control means 60 drives the raising / lowering actuator 37 based on the received operation signal. When the pushing operation of the auger raising button 70e or the auger lowering button 70f is released, the control means 60 stops the raising / lowering actuator 37. As a result, the discharge auger 32 is raised or lowered in response to the pushing operation of the auger raising button 70e or the auger lowering button 70f, and is not raised or lowered when the pushing auger 32 is not pushed. Stop.

  The auger left turn button 70g and the auger right turn button 70h are for turning the discharge auger 32 left and right, respectively. While the auger left turn button 70g or the auger right turn button 70h is being pressed, the control means 60 drives the turning actuator 35 based on the received operation signal. When the pushing operation of the auger left turning button 70g or the auger right turning button 70h is released, the control means 60 stops the turning actuator 35. As a result, when the auger left turn button 70g or the auger right turn button 70h is pushed, the discharge auger 32 turns left or right according to the push operation and is not pushed. Stop without turning.

  The cylinder front rotation button 70i and the cylinder rear rotation button 70j are for rotating the grain discharge cylinder 40 forward and backward, respectively. While the cylinder front rotation button 70i or the cylinder rear rotation button 70j is being pressed, the control means 60 drives the cylinder rotation actuator 41 based on the received operation signal. When the push operation of the cylinder front rotation button 70 i or the cylinder rear rotation button 70 j is released, the control means 60 stops the cylinder rotation actuator 41. As a result, when the cylinder front turning button 70i or the cylinder rear turning button 70j is pushed, the grain discharge cylinder 40 turns forward or backward in response to the pushing operation. When the push operation is not performed, it stops without rotating.

  The machine-side operation device 70 is an example of the machine-side operation device, and is not limited to this. Moreover, the various buttons of this machine side operation apparatus 70 are examples of an operation means, and are not limited to this.

  Next, the configuration of the remote control device 80 will be described with reference to FIGS. 5 and 7.

  The remote control device 80 is a member for operating the discharge auger 32 using wireless communication. The remote control device 80 is detachably supported by a support holder provided in the vicinity of the grain discharge port of the operation unit 9 and the discharge auger 32, and is configured to be carried by an operator. The remote operation device 80 includes operation means related to the operation of the discharge auger 32, a transmission unit 81, a battery 82, and a power button 83.

  The transmitting unit 81 is connected to the various buttons, and while the various buttons are being pressed, wirelessly transmits an operation signal corresponding to the pressing operation to the control unit 60 (more specifically, the receiving unit 61 of the control unit 60). To send in. The battery 82 supplies power to the transmission unit 81. The power button 83 can turn on and off the power supply from the battery 82 to the transmission unit 81. When the power button 83 is set to “OFF”, power consumption in a state where the remote operation device 80 is not used is suppressed, and the operation of the discharge auger 32 is forcibly stopped. It is possible to prevent the discharge auger 32 from operating unintentionally and to appropriately respond to changes in the surrounding situation.

  The operation means includes an operation start operation means and other operation means. The operation start operation means is a short press operation, and once the short press operation is performed, the control means 60 that receives the operation signal causes the control of the discharge auger 32 to be started. The other operating means is a long press operation, and during the long press operation, the operation signal is transmitted to the control means 60 and the discharge auger 32 is operated by the control means 60 that has received the operation signal. It is an operation means to be made.

  The operation means is composed of a plurality of buttons in the present embodiment. Among these buttons, an automatic right set / return button (“set / return” display button) 80a is provided as an operation start operation means. Other operating means include an auger clutch button (“clutch” display button) 80d, an auger up button (“up” display button) 80e, an auger down button (“down” display button) 80f, and an auger left turn button ("Left" display button) 80g, auger right turn button ("right" display button) 80h, cylinder front rotation button ("front shooter" display button) 80i, cylinder rear rotation button ("shooter" A “post” display button) 80j.

  The automatic right set / return button 80a automatically and alternately moves the lifting auger 32 to a predetermined position during use or a storage position when not in use (position placed on the auger rest 21). For turning). When the automatic right set / return button 80a is pressed for a short time while the horizontal discharge auger (hereinafter simply referred to as the discharge auger 32) is placed on the auger rest 21, the control means 60 causes the turning actuator 35 and the lifting / lowering to move up and down. The actuator 37 is driven based on the received operation signal. As a result, the discharge auger 32 moves up and down and turns and automatically moves to a predetermined position so that the grain discharge cylinder 40 (grain discharge port) is located on the right side of the machine body. When the automatic right set / return button 80a is pressed for a short time when the discharge auger 32 is not placed on the auger rest 21, the control means 60 is based on the operation signals received by the turning actuator 35 and the lifting actuator 37. Drive. As a result, the discharge auger 32 moves up and down and pivots automatically to the storage position when not in use. As described above, the automatic right set / return button 80a has the function of two buttons, that is, the automatic right set button 70a and the automatic return button 70c in the apparatus-side operation device 70 with one button.

  The auger clutch button 80d is for turning the auger clutch 33 on and off. While the auger clutch button 80d is being pressed, the control means 60 turns the auger clutch 33 "ON". When the pushing operation of the auger clutch button 80d is released, the control means 60 turns off the auger clutch 33. As a result, the discharge auger 32 discharges the grain to the outside only when the auger clutch button 80d is pressed. However, when the horizontal discharge auger cylinder 36 is placed on the auger rest 21 or when the opening on the front end side of the grain discharge cylinder 40 is arranged in the horizontal direction, the auger clutch button 80d is Even if it is pushed, the control means 60 does not “turn on” the auger clutch 33. Thereby, the discharge | emission of the grain by erroneous operation can be prevented.

  The auger up button 80e and the auger down button 80f are for raising and lowering the discharge auger 32, respectively. While the auger up button 80e or the auger down button 80f is being pressed, the control means 60 drives the lifting actuator 37 based on the received operation signal. When the pushing operation of the auger up button 80e or the auger down button 80f is released, the control means 60 stops the lifting actuator 37. As a result, the discharge auger 32 moves up or down in response to the pushing operation of the auger raising button 80e or the auger lowering button 80f, and does not move up or down when the pushing auger 32 is not pushed. Stop.

  The auger left turn button 80g and the auger right turn button 80h are for turning the discharge auger 32 left and right, respectively. While the auger left turn button 80g or the auger right turn button 80h is being pressed, the control means 60 drives the turning actuator 35 based on the received operation signal. When the pushing operation of the auger left turning button 80g or the auger right turning button 80h is released, the control means 60 stops the turning actuator 35. As a result, when the auger left turn button 80g or the auger right turn button 80h is pushed, the discharge auger 32 turns left or right according to the push operation, and when it is not pushed. Stop without turning.

  The cylinder front rotation button 80i and the cylinder rear rotation button 80j are for rotating the grain discharge cylinder 40 forward and backward, respectively. While the cylinder front rotation button 80i or the cylinder rear rotation button 80j is being pressed, the control means 60 drives the cylinder rotation actuator 41 based on the received operation signal. When the push operation of the cylinder front rotation button 80i or the cylinder rear rotation button 80j is released, the control means 60 stops the cylinder rotation actuator 41. As a result, when the cylinder front turning button 80i or the cylinder rear turning button 80j is pushed, the grain discharge cylinder 40 turns forward or backward in response to the pushing operation. When the push operation is not performed, it stops without rotating.

  The remote operation device 80 is an example of the remote operation device according to the present invention, and is not limited to this. The various buttons of the remote operation device 80 are an example of operation means of the remote operation device 80, and are not limited thereto.

The operation starting operation means is not limited to the automatic right set / return button 80a.
For example, instead of the auger clutch button 80d as the other operation means, a remote control device includes an “ON” button for setting the auger clutch 33 to “ON” and a “OFF” button for setting the auger clutch 33 to “OFF”. When the “ON” button is short-pressed, the control means 60 that has received the operation signal starts the operation of the discharge auger 32 (grain discharge), and then the “OFF” button is short-pressed. Then, when the operation of the discharge auger 32 (the discharge of the grain) is stopped by the control means 60 that has received the operation signal, the “ON” button becomes the operation start operation means.
Further, instead of the auger ascending button 80e which is the other operation means, the remote operation device is provided with an ascending start / stop button for starting or stopping the ascending of the discharge auger 32, and the ascending start / stop button is operated once for a short time. Then, when the control means 60 that has received the operation signal starts to raise the discharge auger 32, and then the lift start / stop button is pressed again for a short time, the control means 60 that has received the operation signal causes the discharge auger 32 to rise. In the case where the ascent of 32 is configured to stop, the ascending start / stop button becomes the operation starting operation means.

When the automatic right set / return button 80a, which is an operation start operation means, is pressed once for a short time, the remote operation device 80 transmits an operation confirmation signal of the remote operation device 80 from the transmitter 81 of the remote operation device 80 to the control means. 60 to be transmitted intermittently.
Hereinafter, the operation confirmation signal of the remote control device 80 will be described in detail.

The operation confirmation signal transmitted from the remote operation device 80 to the control means 60 is a signal for informing the control means 60 that the button of the remote operation device 80 has been pressed. That is, it is a signal for notifying the control means 60 that the remote operation device 80 is operating the discharge auger 32 by pushing a button.
Transmission from the operation confirmation signal to the control means 60 is started and continued with the short press operation of the automatic right set / return button 80a, which is the operation start operation means. That is, when the automatic right set / return button 80a is pressed, two types of signals, that is, an operation signal for the automatic right set / return button 80a and an operation confirmation signal are transmitted from the remote control device 80. Become. However, the operation confirmation signal in this case may be the same signal as the operation signal of the automatic right set / return button 80a.
While the operation confirmation signal is transmitted from the remote operation device 80, the control means 60 operates the actuators 35... So as to operate the discharge auger 32 corresponding to the operation signals of various buttons of the remote operation device 80. 37 and 41 are driven. That is, the operation signal of the operated button is transmitted from the remote operation device 80 to the control means 60, and the discharge auger 32 is in operation. On the other hand, the control means 60 controls the control means 60 from the remote operation device 80 because the operation confirmation signal is, for example, insufficient power of the battery 82, a failure of the transmission unit 81, or a change in the usage status of the remote operation device (such as the radio cannot be received). If not, the operation of the discharge auger 32 is stopped.

The operation confirmation signal is intermittently transmitted from the remote operation device 80. That is, the operation confirmation signal is transmitted intermittently, that is, with an interval, when the automatic right set / return button 80a is pressed. The interval may be a constant interval or an irregular interval. Since the operation confirmation signal is intermittently transmitted, the control means 60 intermittently receives the operation confirmation signal from the remote operation device 80, and operates the discharge auger 32 during that time. Then, after the control means 60 receives the operation confirmation signal (and the operation signals of the various buttons) once and can receive the next operation confirmation signal without exceeding the first set time, the control means 60 is provided with the remote operation device. 80 operation confirmation signals are continuously received. That is, even if the operation confirmation signal cannot be continuously received, the control means 60 can move the discharge auger that moves toward the predetermined position or the storage position if the time when the operation confirmation signal cannot be received is within the first set time. The operation (lifting or turning) 32 is not stopped (the operation is continued).
The first set time is set in advance and stored in the storage device 63 of the control means 60.

  If the operation confirmation signal from the remote operation device 80 cannot be received beyond the first set time, the control means 60 drives the actuators 35 and 37 corresponding to the operation signal of the automatic right set / return button 80a. It stops, and it is comprised so that raising / lowering and turning of the discharge auger 32 which moves toward the said predetermined position or a storage position may be stopped on the way. That is, the operation confirmation signal is intermittently transmitted from the remote control device 80 to the control means 60, and the control means 60 receives the operation confirmation signal once and then continues to the next time even if the first set time elapses. If the operation confirmation signal cannot be received, the operation (elevating or turning) of the discharge auger 32 is stopped because the continuous reception of the operation confirmation signal is interrupted.

Moreover, as shown in FIG. 5, the combine 1 can be set as the structure which provides the 1st setting time change means 91 which can change said 1st setting time arbitrarily.
The first set time changing means 91 is composed of a rotary dial, a switch, or the like, and is disposed in at least one of the machine side operation device 70, the remote operation device 80, the driving unit 9, and the like. The first set time changing unit 91 is connected to the control unit 60. Then, when the first set time changing means 91 is operated, the setting time currently set by the control means 60 is changed arbitrarily long or short based on the operation.
By providing the first set time changing means 91 in this way, the operator can arbitrarily change the setting of the first set time, and the workability can be improved. Further, the power consumption can be suppressed by increasing the interval.

  Next, control to the discharge auger 32 when the automatic right set / return button 80a is operated will be described with reference to the flowchart of FIG.

When various buttons of the remote operation device 80 are pressed, the operation signals are transmitted from the transmission unit 81 to the reception unit 61 of the control means 60. The control means 60 inputs the operation signal received by the receiving unit 61 to the arithmetic processing device 62.
First, in step 101, the control means 60 determines whether or not any of the various buttons of the remote operation device 80 has been pressed.

As a result, when one of the various buttons of the remote operation device 80 is pressed and the control unit 60 inputs an operation signal from the receiving unit 61 to the arithmetic processing unit 62, the control unit 60 performs the step. To step 102.
On the other hand, when none of the various buttons of the remote control device 80 is pressed and the receiving unit 61 does not receive the operation signal, the control unit 60 shifts the step to step 101 again. .

  In step 102, the control means 60 determines whether or not the operation signal input to the arithmetic processing unit 62 is an operation signal for the automatic right set / return button 80a, that is, the automatic right set / return button 80a (operation start operation means). It is determined whether or not is pressed.

As a result, when the operation signal input to the arithmetic processing unit 62 by the control means 60 is not the operation signal of the automatic right set / return button 80a, that is, the automatic right set / return button 80a (operation start operation means) is pushed. If not, the control unit 60 shifts the step to step 103.
On the other hand, when the operation signal input to the arithmetic processing unit 62 by the control means 60 is an operation signal for the automatic right set / return button 80a, that is, the automatic right set / return button 80a (operation start operation means) is pushed. In that case, the control means 60 shifts the step to step 106.

  In step 103, the control means 60 starts driving the actuators 35, 37, and 41 corresponding to the pressing operations of various buttons of the remote control device 80 that have been pressed, that is, various buttons other than the automatic right set / return button 80 a. Then, the discharge auger 32 is moved up and down and turned or the rotation of the grain discharge cylinder 40 of the discharge auger 32 is started. Then, the control unit 60 shifts the step to step 104.

  In step 104, the control means 60 determines whether or not the operation signal transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing unit 62 via the reception unit 61, that is, the operation of pressing various buttons. It is determined whether it has continued from the start.

As a result, when the operation signal transmitted from the transmission unit 81 of the remote operation device 80 is not input to the arithmetic processing device 62 via the reception unit 61, that is, when the pressing operation of various buttons is released, The control unit 60 shifts the step to step 105.
On the other hand, when the operation signal transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing unit 62 via the reception unit 61, that is, when the pressing operation of various buttons is continued from the start. The control means 60 shifts the step to step 104 again. In this case, the control means 60 continues the operation of the discharge auger 32.

  In step 105, the control means 60 stops the driving of the actuators 35 and 37 corresponding to the pressing operation of various buttons of the remote operation device 80 and stops the operation of the discharge auger 32.

  In step 106, the control means 60 starts driving the actuators 35 and 37 corresponding to the pressing operation of the automatic right set / return button 80 a of the remote control device 80, and starts the operation of the discharge auger 32. Then, the control means 60 shifts the step to step 107.

  In step 107, the control means 60 determines whether any one of the various buttons of the remote operation device 80 is pressed and the operation signal received by the receiving unit 61 is input to the arithmetic processing device 62. .

As a result, when one of the various buttons of the remote operation device 80 is pressed and the control unit 60 inputs an operation signal from the receiving unit 61 to the arithmetic processing unit 62, the control unit 60 performs the step. To step 102.
On the other hand, when none of the various buttons of the remote control device 80 is pressed and the receiving unit 61 does not receive an operation signal, the control unit 60 shifts the step to step 108.

  In step 108, the control means 60 sends the operation confirmation signal of the remote operation device 80 intermittently transmitted from the transmission unit 81 of the remote operation device 80 to the arithmetic processing device 62 of the control means 60 via the reception unit 61. It is determined whether or not the input has been made within the set time.

As a result, the operation confirmation signal of the remote operation device 80 intermittently transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing unit 62 of the control means 60 within the first set time via the reception unit 61. If yes, the control means 60 shifts the step to step 109.
On the other hand, the operation confirmation signal of the remote operation device 80 intermittently transmitted from the transmission unit 81 of the remote operation device 80 is input to the arithmetic processing unit 62 of the control means 60 within the first set time via the reception unit 61. If not, the control means 60 shifts the step to step 110.

  In step 109, the control means 60 determines whether the driving of the actuators 35 and 37 corresponding to the pressing operation of the automatic right set / return button 80a of the remote control device 80 is completed and the raising and lowering and turning of the discharge auger 32 are completed. Determine whether or not.

As a result, when the driving of the actuators 35 and 37 corresponding to the pressing operation of the automatic right set / return button 80a of the remote operation device 80 is completed and the raising and lowering and turning of the discharge auger 32 are completed, the control means 60 Terminates control of the discharge auger 32.
On the other hand, when the driving of the actuators 35 and 37 corresponding to the pressing operation of the automatic right set / return button 80a of the remote control device 80 is not completed, and the raising and lowering and turning of the discharge auger 32 are not completed, The control means 60 shifts the step to step 107.

  Further, in step 110, the control means 60 stops the driving of the actuators 35 and 37 corresponding to the pressing operation of the automatic right set / return button 80a of the remote control device 80, and stops the raising and lowering and turning of the discharge auger 32. . Then, the control means 60 ends the control to the discharge auger 32.

  As described above, the combine 1 includes the operable discharge auger 32 that discharges the grains in the grain tank 17 to the outside, the actuators 35 and 37 that operate the discharge auger 32, and the actuators. 35/37 (actuator for operation) has a control means 60 for driving and an automatic right set / return button 80a (operation start operation means) for starting the operation of the discharge auger 32 by the control means 60; A remote operation device 80 that transmits an operation signal of an automatic right set / return button 80a (operation start operation means) to the control means 60 using wireless communication by supplying power from a battery 82. The remote control device 80 is operated by an automatic right set / return button 80a (operation start operation means). If the operation confirmation signal is intermittently transmitted to the control means 60 and the control means 60 does not receive the operation confirmation signal beyond the first set time, the actuators 35 and 37 (actuation actuators) ) Is controlled to stop the operation of the discharge auger 32.

With such a configuration, the control means 60 receives the operation confirmation signal once after the operation of the automatic right set / return button 80a (operation start operation means) of the remote operation device 80, and then receives the operation confirmation signal as the first. If it can be received before the set time has elapsed, the operation of the discharge auger 32 is not stopped. That is, even if the operation confirmation signal cannot be received continuously, the control unit 60 does not stop (continue) the operation of the discharge auger 32 if the time when the operation confirmation signal cannot be received is within the first set time.
Further, since the operation confirmation signal is intermittently transmitted from the remote operation device 80, the power consumption of the remote operation device 80 can be suppressed and the life of the battery 82 can be extended. Therefore, during the operation of the discharge auger 32, the remaining power of the battery 82 of the remote operation device 80 is insufficient, and the operation confirmation signal is not transmitted from the remote operation device 80, whereby the control means 60 operates the discharge auger 32. Can be reduced.
Therefore, when operating the discharge auger 32 by the remote control device 80, it is possible to avoid unintentionally stopping the operation of the discharge auger 32 as much as possible, and to suppress a decrease in workability.

  And the operation confirmation signal transmitted intermittently from the remote control device 80 to the control means 60 can be configured to be transmitted only during the second set time. That is, after the operation start operation means is operated, the transmission of the operation confirmation signal can be stopped after the second set time has elapsed.

The second set time is the time when the remote operation device 80 has transmitted the operation confirmation signal for the first time triggered by the short press operation of the automatic right set / return button 80a as the operation start operation means. This is the time until the last operation confirmation signal is transmitted. The second set time is set in advance and stored in the storage device 63 of the control means 60.
In the present embodiment, since the operation start operation means is the automatic right set / return button 80a, the second set time is moved from an arbitrary position when the discharge auger 32 is used to a storage position when not used. It may be set in consideration of the maximum travel time required to do this. That is, since the discharge auger 32 stops when it reaches the storage position when not in use from the arbitrary position during use, the operation confirmation signal of the remote control device 80 is not required after the discharge auger 32 is lifted and stopped. This is because it is not necessary to confirm that the discharge auger 32 can be operated by pressing various buttons of the remote control device 80.
Further, as described above, when the operation start operation means is an “ON” button for setting the auger clutch 33 to “ON”, the Glen tank 17 is operated by the operation of the discharge auger 32 during the second set time. What is necessary is just to set in consideration of the time required from the full state to the empty state. That is, if the Glen tank 17 becomes empty, it is useless even if the discharge auger 32 is operated, and the operation confirmation signal of the remote operation device 80 is unnecessary.

  As described above, the remote control device 80 stops transmission of the operation confirmation signal after the second set time has elapsed after the automatic right set / return button 80a (operation start operation means) is operated. .

  With such a configuration, it is possible to prevent the remote operation device 80 from continuing to transmit the operation confirmation signal in vain. Therefore, the power consumption of the remote operation device 80 can be suppressed and the life of the battery 82 can be extended. Accordingly, during operation of the discharge auger 32, the remaining power of the battery 82 of the remote control device 80 is insufficient, and an operation confirmation signal is not transmitted from the remote control device 80, whereby the control means 60 operates the discharge auger 32. Can be reduced.

Moreover, as shown in FIG. 5, the combine 1 can be set as the structure which provides the 2nd setting time change means 92 which can change said 2nd setting time.
The second set time changing means 92 is composed of a rotary dial or switch or the like, and is disposed in at least one of the machine side operation device 70, the remote operation device 80, the driving unit 9, and the like. The second set time changing unit 92 is connected to the control unit 60. Then, by operating the second set time changing means 92, the control means 60 changes the set time currently set to be arbitrarily long or short based on the operation. The second set time changing means 92 is an example of the set time changing means according to the present invention, and is not limited to this.
By providing the second set time changing unit 92 in this way, the second set time can be arbitrarily changed by the operator, so that workability can be improved.

Next, the structure of the combine 1 which concerns on another embodiment of this invention is demonstrated using FIG.
In addition, in FIG. 9, about the member of the structure same as the said combine 1 which concerns on one Embodiment of this invention, the detailed description is abbreviate | omitted by attaching | subjecting the code | symbol used in another drawing.

In the combine 1 which concerns on another embodiment of this invention, while being provided with the transmission part 161 in the control means 60, it can be set as the structure which provides the receiving part 181 in the remote control apparatus 80. FIG.
When the operation of the discharge auger 32 is completed, the transmission unit 161 of the control means 60 transmits the completion of the operation to the remote operation device 80 (more specifically, the reception unit 181 of the remote operation device 80) by radio. Is. The receiving unit 181 of the remote operation device 80 receives a signal transmitted wirelessly from the transmitting unit 161 of the control means 60 of the combine 1.
The “operation of the discharge auger 32” is assumed to be the operation of the discharge auger 32 started by the pressing operation of the operation start operation means among the operation means of the remote operation device 80. Specifically, when the automatic right set / return button 80a, which is the operation starting operation means in this embodiment, is pressed, the discharge auger 32 is automatically operated by the control means 60, and when it reaches a predetermined position, the operation is started. (Raising and lowering and turning) are stopped (finished). When the operation of the discharge auger 32 ends, the control means 60 sends a signal indicating that the operation of the discharge auger 32 has ended (hereinafter referred to as an end confirmation signal) from the transmission unit 161 of the control means 60 to the remote control device 80. The data is transmitted to the receiving unit 181 wirelessly.
When receiving the end confirmation signal by the receiving unit 181, the remote operation device 80 receives the end of the automatic right set / return button 80 a (from the pressing operation of the automatic right set / return button 80 a) from the transmission unit 81 of the remote operation device 80. The transmission of the operation confirmation signal of the remote operation device 80 that is intermittently transmitted to the receiving unit 61 is stopped.

  As described above, when the operation of the discharge auger 32 started by the operation of the operation start operation means ends, the control means 60 transmits an end confirmation signal to the remote operation device 80, and the remote operation device 80 receives the end confirmation signal and stops transmitting the operation confirmation signal to the control means 60.

  With such a configuration, when the operation of the discharge auger 32 is finished, the transmission of the operation confirmation signal from the transmission unit 81 of the remote operation device 80 can be stopped, so the remote operation device 80 wastes the operation confirmation signal. It is possible to prevent the data from continuing to be transmitted. Therefore, the power consumption of the remote operation device 80 can be suppressed and the life of the battery 82 can be extended. Accordingly, during operation of the discharge auger 32, the remaining power of the battery 82 of the remote control device 80 is insufficient, and an operation confirmation signal is not transmitted from the remote control device 80, whereby the control means 60 operates the discharge auger 32. Can be reduced.
