Description

According to the present invention, a work machine main body is provided with an operated part and machine-side control means for controlling the operation of the operated part, and a plurality of types of operation commands regarding the operation of the operated part are controlled by the machine-side control. Manual operation type radio command means for commanding by means of a radio signal is provided, and the radio command means is configured to command the plurality of types of operation commands, and the command operation means to perform the plurality of types of command commands. It is configured to be switchable between an operating state in which a corresponding wireless signal is output when an operation command is issued, and a pause state in which the corresponding wireless signal is not output even when the plurality of types of operation commands are instructed by the command operation means. The present invention relates to a wireless operating device for a working machine that is configured to include output control means and an operation state switching means for switching the output control means between the operating state and the resting state.

  The wireless operating device for the working machine is located at a position away from the working machine main body, for example, when the operating part of the working machine is operated or when the operating part is stopped. It is used when operating the operation. The wireless command means commands the operation command for the operation of the operated part by radio signal, so that the operator can carry it to a position where it is easy to check the work status, While grasping, the operation of the operated portion of the work machine can be appropriately operated.

  For example, when a movable actuating part is provided as the operated part, the movable part is operated according to the work situation to appropriately perform work using the work implement, or the driving control part as the operated part. If the notification means is provided, the notification means is activated according to the work situation, and the driver on the work machine body can be called to perform joint work smoothly. It can be done.

  Also, when the operator decides not to use the wireless command means for a while and carries it in a pocket, etc., the command operation means of the wireless command means is erroneously operated due to some momentum, and the work machine body is covered. In order to prevent the operation of the operation unit from being operated unexpectedly, even if the command operation means of the wireless command means is erroneously operated by switching the output control means from the operating state to the sleep state by the operation state switching means, The output control means can be configured not to output a radio signal.

  As a conventional example of a wireless operating device for such a working machine, there is one in which the operation state switching means is constituted by a power switch that switches between supplying and not supplying power to the output control means of the wireless command means. (For example, refer to Patent Document 1).

  When the power supply switch is turned off, the output control means is not supplied with power when the power switch is turned off. Therefore, the output control means receives an operation command from the command operation means of the wireless command means. Even if commanded, the corresponding wireless signal is not output, that is, the sleep state is entered. Therefore, when the operator determines that the wireless command means is not used for a while, the command operation means of the wireless command means is erroneously operated by turning off the power switch of the wireless command means. In addition, it is possible to prevent the operated portion of the work machine body from operating unexpectedly.

JP 2003-325032 A

  However, with the above-described conventional configuration, once the output control unit is in a dormant state, even if the operation command is issued by operating the command operation unit of the wireless command unit, as long as the power switch is not turned on, it is possible to respond. No radio signal is output. For this reason, when the operation of the operated part needs to be operated urgently after the output control means has been switched to the sleep state, an operation command is issued without realizing that the operation has been switched to the sleep state. When the command operating means is operated as soon as possible, there is a problem that the operation of the operated part cannot be operated.

  For example, when it is necessary to stop the operation of the operation unit while the movable operation unit as the operated unit is in operation, the operator carrying the wireless command unit is in the dormant state. Without knowing that it has been switched to, when the command operation means is operated to command the stop command, the output control means is in a pause state, so the radio signal corresponding to the stop command is not output and the operation is The operation of the part cannot be stopped.

  Moreover, even if it responds calmly, after the power switch is turned on, a two-step operation such as instructing a stop command by the command operation means is necessary, and the operating unit cannot be stopped quickly. For this reason, if the operation of the operation unit is to automatically move the auger as the operation unit included in the combiner as the work machine to the storage position, foreseeing contact with the obstacle during the movement of the auger. When an operation for urgently stopping the operation of the operating part is performed, such as an emergency stop, it may take time until the stop command is issued, and there may be a problem that the operation part cannot be stopped in time. There was something.

  Further, for example, when it is urgently necessary to call a worker who operates the work implement body, the worker carrying the wireless command means commands a notification start command for starting the notification operation of the notification means. When the command operating means is operated, if the power switch has already been turned off and the output control means has been switched to the hibernation state, the radio signal corresponding to the notification start command is not output, and the notification means is activated. I can not. Therefore, in order to call an operator who operates the work implement main body, the power switch of the wireless command means is turned on to switch the output control means to the operating state, and then a notification start command is commanded by the command operation means. There is a disadvantage that two-step operation is required, and it is impossible to promptly call an operator on the work machine main body side.

  As described above, the conventional wireless operation device for a work machine is inconvenient when the operation command for the operated portion is issued. In other words, in the conventional wireless operating device of the work machine, it is possible to prevent unexpected operation of the operated part due to erroneous operation of the wireless command means, but considering the operability when operating the operated part urgently There was room for improvement in the operability of the wireless command means.

  The present invention has been made in view of the above circumstances, and its purpose is to prevent an erroneous operation of the operated part due to an erroneous operation of the wireless command means, while operating the operated part. It is in the point which provides the wireless operating device of the working machine which can aim at the improvement of property.

  A wireless operating device for a working machine according to the present invention includes a work machine main body including an operated part and machine body side control means for controlling the operation of the operated part. Manual operation type wireless command means for commanding various operation commands to the airframe side control means by radio signals is provided, and the wireless command means is command operation means for commanding the plurality of types of operation commands; An operating state in which a corresponding radio signal is output when the command operation means is commanded by the plurality of types of operation commands, and a corresponding radio signal is not output even if the command operation means is commanded by the plurality of types of operation commands. A wireless operating device for a working machine comprising output control means configured to be switchable between a resting state and an operation state switching means for switching the output control means between the operating state and the resting state. The first feature configuration is that the operation state switching means is a specific specific operation command among the plurality of types of operation commands by the command operation means when the output control means is in the pause state. Is instructed to switch the output control means to the operating state.

  According to the first characteristic configuration of the present invention, when the specific operation command is instructed by the command operation unit when the output control unit is in the pause state, the operation state switching unit switches the output control unit to the operating state. Even if the control means is in a resting state, if a specific operation command is commanded by the command operation means, a radio signal corresponding to the specific operation command is output.

  Therefore, if the output control means is in the pause state and the operation command is issued by the command operation means unless the operation control is switched, the operation is commanded by the specific operation command when the corresponding radio signal is not output. When it becomes necessary to operate the operated part urgently, the operation of the operated part is operated only by the operation of instructing the specific operation command without performing a separate operation for switching the output control means to the operating state. be able to.

  That is, even if the output control means is switched to the pause state so that the operated part is not operated unexpectedly due to an erroneous operation of the command operation means, the worker is the same as when the operation command is issued in the operating state. Since the operation of the operated part operated by the specific operation command can be operated by the operation, it is necessary to perform a different operation depending on the operation state of the output control means when operating the operated part. In other words, it is only necessary to perform an operation for instructing the specific operation command without being aware of the operation state of the output control means.

  As described above, according to the first characteristic configuration of the present invention, it is possible to prevent an erroneous operation of the operated portion due to an erroneous operation of the wireless command means, and to improve operability when operating the operated portion. It came to obtain the wireless operating device of the work machine which can be done.

  According to a second characteristic configuration of the present invention, in the first characteristic configuration of the present invention, the operation state switching means switches between the operation state and the hibernation state by intermittently supplying power to the output control means. There is in point.

  According to the second characteristic configuration of the present invention, when the output control unit is switched to the hibernation state by the operation state switching unit, power is not supplied to the output control unit, so when the output control unit is in the hibernation state, The power consumption of the wireless command means is reduced. Therefore, when the wireless command means is not used, switching the output control means to the hibernation state can reduce wasteful power consumption, and the power source for operating the wireless command means (for example, a dry battery or a rechargeable battery). Battery, etc.) can last longer.

  Thus, according to the second characteristic configuration of the present invention, it is possible to prevent an erroneous operation of the operated part due to an erroneous operation of the wireless command means, and to improve operability when operating the operated part. In addition, it has resulted in a wireless operating device for a work machine having good maintainability in that it is possible to perform work such as battery replacement and rechargeable battery charging as much as possible.

  According to a third characteristic configuration of the present invention, in the second characteristic configuration of the present invention, the wireless command means is a manual operation for commanding an operation command for setting the output control means to the operating state and a pause command for setting the hibernation state. The operation state switching means is configured to provide the output control means with the operating state and the operation command based on the operation command and the pause command instructed by the on / off command device. When the output control means is switched to the resting state, and the operation command of the output control means is not continuously commanded for a set time, the output control means is automatically put into the resting state. It is in the point which is comprised so that it may switch to.

  According to the third characteristic configuration of the present invention, the operator can put the output control means in a paused state by operating the on / off command means to give a pause command. Further, when the operator does not continuously issue the control command and stop command by the command operating means for a set time, the output control means is automatically switched to the resting state by the operation state switching means. Therefore, not only when the operator consciously operates the on / off command means, but also when the operator does not operate the on / off command means, the erroneous operation of the operated part due to the erroneous operation of the command operation means is prevented or wasted. Power consumption can be reduced.

  Then, when the output control means is in a resting state, when the operator commands a specific operation command, the output control means returns to the operating state, and a radio signal corresponding to the specific operation command is output from the wireless command means. Therefore, even if the output control means is automatically switched to the hibernation state by the operation state switching means and the operator does not recognize that the output control means is in the hibernation state, the operation of the operated portion is performed. When it becomes necessary to operate the operation unit, the operation of the operated part can be operated by operating the command operation means to command a specific operation command.

  As described above, according to the third characteristic configuration of the present invention, it is possible to prevent an erroneous operation of the operated portion due to an erroneous operation of the wireless command means, and to improve the operability when operating the operated portion. In addition, even when the output control means is automatically switched to the hibernation state in order to prevent erroneous operation of the wireless command means and to save power, the specific operation command is not conscious of the operating state of the output control means. As a result, a wireless operating device for work machines that can accurately and quickly be commanded has been obtained.

  According to a fourth characteristic configuration of the present invention, in any one of the first to third characteristic configurations of the present invention, a movable actuating portion is provided as the operated portion, and the command operating means of the wireless command means is A command for controlling the operation of the operation unit and a stop command for stopping the operation of the operation unit, the operation state switching unit of the wireless command unit, and the output control unit being in the inactive state. When the stop command as the specific operation command is instructed by the command operation means, the output control means is switched to the operating state.

  According to the fourth characteristic configuration of the present invention, when the stop command is commanded by the command operating means when the output control means is in the pause state, the operation state switching means switches the output control means to the operating state. Even if the means is in a resting state, if a stop command is issued by the command operation means, a radio signal corresponding to the stop command is output.

  Therefore, it is necessary to urgently stop the operation of the operating unit in a state where the output control means is in a pause state and the corresponding radio signal is not output even if the command operation means is commanded unless the operation is switched to the operation state. If this occurs, it is possible to stop the operation of the operating portion only by an operation of instructing a stop command without performing a separate operation of switching the output control means to the operating state.

  In other words, even if the output control means is switched to the resting state in order to prevent the operating part from operating unexpectedly due to an erroneous operation of the command operating means, the worker is similar to the case where the stop command is instructed in the operating state. Since the operation of the operation unit can be stopped by the operation, when the operation of the operation unit is stopped, it is not necessary to perform a different operation depending on the operation state of the output control means, and the operation state of the output control means is conscious. It is sufficient to perform an operation only to issue a stop command without performing the operation.

  As described above, according to the fourth characteristic configuration of the present invention, it is possible to prevent malfunction of the operating unit due to erroneous operation of the wireless command means, and to improve operability when stopping the operation of the operating unit. It came to obtain the wireless operating device of the work machine which can be done.

  According to a fifth characteristic configuration of the present invention, in any one of the first to third characteristic configurations of the present invention, a calling notification means provided in a driving control unit of the work implement main body is provided as the operated portion. The command operation means of the wireless command means is configured to command a notification start command for starting the notification operation of the notification means and a notification stop command for stopping the notification operation of the notification means, and the wireless command When the notification start command as the specific operation command is instructed by the command operation means when the output control means is in the pause state, the operation state switching means of the means is activated. It is in the point comprised so that it may switch to a state.

  According to the fifth characteristic configuration of the present invention, when the notification operation command is instructed by the command operation unit when the output control unit is in the pause state, the operation state switching unit switches the output control unit to the operating state. Even when the control means is in a resting state, when a command start command is commanded by the command operating unit, a radio signal corresponding to the report start command is output.

  Therefore, in the state where the output control means is in a dormant state and the operation command is instructed by the command operation means unless it is switched to the operating state, the notification operation of the notification means is urgently started. When the necessity arises, the notifying operation of the notifying means can be started only by the operation of instructing the notifying start command without performing a separate operation for switching the output control means to the operating state.

  In other words, even if the output control means is switched to the pause state in order to prevent the notification means from being inadvertently activated due to an erroneous operation of the command operation means, the operator may issue a notification start instruction in the operating state. Since the notification operation of the notification means can be started by a similar operation, when the notification operation of the notification means is started, there is no need to perform a different operation depending on the operation state of the output control means. What is necessary is just to perform operation only to instruct | indicate an alerting | reporting start command, without being conscious of an operation state.

  As described above, according to the fifth characteristic configuration of the present invention, it is possible to prevent malfunction of the notifying means due to erroneous operation of the wireless command means, but to improve operability when the notifying operation of the notifying means is started. It came to obtain the wireless operation device of the work machine which can be.

  According to a sixth feature of the present invention, in any one of the first to third feature configurations of the present invention, the operated part is equipped as a movable operating part and a driving control part of the work implement body. Calling notification means is provided, and the command operation means of the wireless command means is configured to control the operation of the operation unit, a stop command to stop the operation of the operation unit, and a notification operation of the notification unit. A command to start notification and a notification stop command to stop the notification operation of the notification means, the operation state switching means of the wireless command means, the output control means is in the pause state In this case, when the stop command or the notification start command as the specific operation command is instructed by the command operation unit, the output control unit is configured to switch to the operation state. Located in.

  According to the sixth feature of the present invention, when the output control means is in the pause state, the operation state switching means switches the output control means to the operating state when the command operation means issues a stop command or a notification start command. Therefore, even when the output control means is in a pause state, if a stop command or a notification start command is commanded by the command operation means, a radio signal corresponding to the stop command or the notification start command is output.

  Therefore, it is necessary to urgently stop the operation of the operating unit in a state where the output control means is in a pause state and the corresponding radio signal is not output even if the command operation means is commanded unless the operation is switched to the operation state. If there is a need to start the notification operation of the notification means urgently, an operation for instructing a stop command or a notification start command without performing a separate operation for switching the output control means to the operating state. Only the operation of the operating part can be stopped, or the notification operation of the notification means can be started.

  In other words, even if the output control means is switched to the pause state in order to prevent the operating section and the notification means from being unexpectedly operated due to an erroneous operation of the command operation means, the operator can stop the command or start the notification in the operation state. The operation of the operating unit can be stopped or the notification operation of the notification unit can be started by the same operation as in the case of instructing the operation, so that the operation of the operation unit is stopped or the notification unit starts the notification operation. In this case, it is not necessary to perform a different operation depending on the operation state of the output control means, and it is sufficient to perform an operation only for instructing a stop command or a notification start command without being aware of the operation state of the output control means.

  As described above, according to the sixth characteristic configuration of the present invention, it is possible to prevent malfunction of the operating unit and the notification unit due to erroneous operation of the wireless command unit, and operability and notification when stopping the operation of the operating unit. It came to obtain the wireless operating device of the working machine which can aim at the improvement of operativity in the case of starting the alerting | reporting operation | movement of a means.

  According to a seventh feature configuration of the present invention, in any one of the fourth to sixth feature configurations of the present invention, the work machine main body includes the control command for the operation of the operation unit and the operation of the operation unit. A body-side command means for commanding the stop command to stop the aircraft, and the body-side control means is configured such that the stop command is commanded by one of the wireless command means and the machine-side command means and the other When the control command is issued, the operation unit is stopped with priority given to the stop command.

  According to the seventh characteristic configuration of the present invention, when a stop command is commanded by one of the wireless command means and the command means on the airframe side and a control command is commanded by the other, the stop command is given priority. Since the operation is stopped, when the operator who operates the wireless command means and the operator who operates the command means on the aircraft side jointly handle the work machine, the operator who operates the command means on the aircraft side When careless operation of the operating part is performed due to carelessness, an operator carrying the wireless command means that has noticed it operates the command operation means of the wireless command means to issue a stop command. Thus, inappropriate operation of the operating unit can be stopped.

  Even if the output control unit of the wireless command means is in a resting state or in an operating state, it is possible to issue a stop command simply by operating the command operating means and issuing a stop command. Because the work situation has not been used for a while, even if the output control means is automatically switched to the sleep state based on the pause command that the operator has previously commanded by the on / off command means or An appropriate stop command can be commanded to stop an inappropriate operation of the operating unit.

  On the other hand, when the operating part is inappropriately operated due to the carelessness of the operator who operates the wireless command means, the operator who operates the command means on the aircraft side operates the command means on the aircraft side. Then, by issuing a stop command, inappropriate operation of the operating unit can be stopped.

  As described above, according to the seventh characteristic configuration of the present invention, it is possible to prevent malfunction of the operating part due to erroneous operation of the wireless command means, but it is possible to stop the operation of the operating part at any time by a simple operation, In the case where the work machine main body is provided with the control means for operating the operating section and the command means on the airframe side for instructing the stop command to stop the operation of the operating section, the command means on the airframe side is provided. When the operating part is improperly operated by the carelessness of either the operator operating the wireless command means or the operator operating the wireless command means, the other operator commands the stop command to operate the operating part. As a result, the wireless operating device of the working machine that can prevent the occurrence of an unexpected situation due to an operation error of the operating unit has been obtained.

  According to an eighth feature of the present invention, in the seventh feature of the present invention, when the aircraft-side control means is instructed by the control command from both the wireless command means and the aircraft-side command means, It is the point which is comprised so that the operation | movement of the said action | operation part may be controlled giving priority to the said control instruction | command of a radio | wireless instruction | command means.

A switch for switching between the grain discharge state and the discharge stop state, wherein the fuselage-side control means swings and raises and lowers the grain discharge auger. The wireless command means and the command means on the airframe side are configured to control, as the control command, a command for turning and raising / lowering the grain discharge auger and at least the grain from the discharge stop state. This is in that a command for switching to the grain discharge state is commanded.

  According to the ninth characteristic configuration of the present invention, as a control command by the wireless command means, a command for turning and raising / lowering the grain discharge auger and a command for switching from the discharge stop state to the grain discharge state are commanded by radio signals. Based on the control command received by the airframe side control means, the operation of the turning up / down drive means and the discharge drive means is controlled. Therefore, the grain discharge auger can be turned and moved up and down by instructing a control command by the wireless command means.

  When the output control means of the wireless command means is in a paused state, when the command operation means issues a stop command to stop the operation of the grain discharge auger, the operation state switching means causes the output control means to operate. Therefore, even if the output control means is in the pause state before the stop command is issued by the command operating means, if the stop command is issued, the output control means is switched to the operating state and the stop command is issued. Commanded by radio signal. Then, based on the stop command received by the fuselage-side control means, the operation of the swivel raising / lowering drive means is stopped to stop the turning action and the raising / lowering action of the grain discharging auger, and the grain discharging auger is switched to the discharging stop state. Controls the operation of the discharge drive means. Therefore, even if the operation state of the output control means before the stop command is instructed by the command operating means is in the pause state or in the operating state, the stop instruction is instructed by the command operating means of the wireless command means. By doing so, the turning up and down operation and the grain discharging operation of the grain discharging auger can be stopped.

  Thus, for example, as a control command, a movement command for turning and raising / lowering the grain discharge auger to automatically move it to the storage position is instructed, and the turning / lifting operation is performed so that the grain discharge auger moves to the storage position. When the operator carrying the wireless command means finds an obstacle etc. at the destination of the grain discharge auger and immediately stops the operation of the grain discharge auger to avoid contact with this, Whether the output control means of the wireless command means is in a resting state or in an operating state, the turning operation and the raising / lowering operation of the grain discharge auger can be quickly stopped by only one operation for instructing the stop instruction. .

  In addition, as a control command, a command to switch the grain discharge auger from the discharge stop state to the grain discharge state is commanded, and when the grain is discharged to the loading platform of the grain transport vehicle by the grain discharge auger, When the operator carrying the wireless command means discovers that the discharge continues beyond the allowable discharge amount and immediately stops the grain discharge, the output control means of the wireless command means Regardless of whether it is in a resting state or in an operating state, the grain discharging auger can be switched to the discharging stopped state by only one operation for instructing a stop command, and the grain discharging operation can be quickly stopped.

  As described above, according to the ninth characteristic configuration of the present invention, the malfunction of the grain discharge auger due to the erroneous operation of the wireless command means can be prevented, but the operability when the operation of the grain discharge auger is stopped is improved. It came to obtain the combine type radio | wireless operating device which can aim at.

Further, in the state where the operation lever 20A is returned to the center position, commands for turning operation and raising / lowering operation of the auger 9 are not instructed. It is possible to return to the center position by releasing the finger from the position and stop the ascending command, descending command, left turn command, and right turn command.

  As shown in FIGS. 2 and 5, an automatic switch 21 for instructing a movement command for automatically moving the auger 9 to the storage position or the target discharge position is provided near the operation unit 20, and the movement A stop switch 22 for instructing a movement stop command for stopping the auger 9 therein, a discharge position setting volume 23 for setting the target discharge position, and a grain for instructing the start of the grain discharge operation of the auger 9 A clutch on / off switch 24 composed of a two-position switching toggle switch for instructing a discharge command or a discharge stop command for commanding stop of the grain discharge operation of the auger 9 is provided.

  When the clutch on / off switch 24 is located at the off position, the discharge clutch 13 is turned off, and when the clutch on / off switch 24 is located at the on position, the discharge clutch 13 can be turned on. Therefore, a grain discharge command is commanded by switching the clutch on / off switch 24 from the off position to the on position, and a discharge stop command is commanded by switching the clutch on / off switch 24 from the on position to the off position.

  The combine main body is provided with a microcomputer-based control device H as a machine-side control means, and the control device H includes the turning position detection sensor Ry, the upper limit switch 14, and the command switches S1, S2 of the operation unit 20. , S3, S4, the automatic switch 21, the stop switch 22, the discharge position setting volume 23, and the clutch on / off switch 24 are input through wires, and control corresponding to the operation of the command switches is executed. Is configured to do.

  That is, the control device H raises the lifting hydraulic cylinder 15 to raise the auger 9 when the raising command switch S1 is turned on by the operation lever 20A being tilted forward and the raising command is commanded. When the lowering command switch S2 is turned on and the lowering command is commanded when the operation lever 20A is tilted rearward, the lifting hydraulic cylinder 15 is lowered to lower the auger 9. When the operation lever 20A is tilted to the left side and the right turn command switch S3 is turned on to issue a right turn command, the turning motor M2 is turned to the right in order to turn the auger 9 to the right. When the operation lever 20A is tilted to the right side and the left turn command switch S4 is turned on to issue a left turn command, the auger 9 is turned to turn left. Actuating the over data M2 to the left turning side.

  Further, when the movement command is instructed, the control device H determines whether or not the auger 9 is located at the storage position based on detection information from the turning position detection sensor Ry and the like, and according to the position of the auger 9. Thus, in order to automatically move the auger 9 to the retracted position or the target discharge position, the operations of the lifting hydraulic cylinder 15 and the swing motor M2 are controlled.

  That is, when the automatic switch 21 is pushed and a movement command is issued, the control device H, when the auger 9 is located at the retracted position, moves the lifting hydraulic cylinder to move the auger 9 to the target discharge position. 15 and the swing motor M2 are operated, and when the auger 9 is located at the discharge position, the lifting hydraulic cylinder 15 and the swing motor M2 are operated to move the auger 9 to the retracted position.

  Further, the control device H is configured to turn the auger 9 into a grain discharge state when a grain discharge command is commanded, and to set the auger 9 into a discharge stop state when a discharge stop command is commanded. It is configured to control the operation of the motor M1.

  That is, when the clutch on / off switch 24 is switched from the off position to the on position and a grain discharge command is issued, the control device H rotates the clutch motor M1 in a forward direction so that the auger 9 is in a grain discharge state. When the clutch on / off switch 24 is switched from the on position to the off position and a discharge stop command is instructed, the clutch motor M1 is driven in the reverse direction so that the auger 9 is in the discharge stop state.

  Thus, the main body of this combine is a stop command such as an auger 9 lift command, a descend command, a left turn command, a right turn command, a move command and a grain discharge command, and a stop command and a discharge stop command. As a command means on the airframe side for instructing a command, an operation lever 20A, an automatic switch 21, a stop switch 22, and a clutch on / off switch 24 are provided. It is comprised so that the command which switches to a grain discharge | emission state may be commanded.

  In this combine, a manually operated radio that commands a control command for the turning up / down operation and the grain discharging operation of the auger 9 and a stop command for stopping the turning up / down operation and the grain discharging operation of the auger 9 by radio signals. A wireless remote controller 42 is provided as a formula command means. The wireless remote controller 42 is mainly used when an operator in the vicinity of the grain transporting vehicle N operates when performing a grain discharging operation to the grain transporting vehicle N.

  More specifically, as shown in FIG. 6 and FIG. 7, the wireless remote controller 42 is configured as a small and lightweight device so that the operator can easily carry it. It is configured to transmit as a radio signal corresponding to each of a control command and a stop command as a plurality of operation commands commanded by a switch.

  The wireless remote controller 42 includes an ascending command switch 43 that commands an ascending command to raise the auger 9, a descending command switch 44 that commands a descending command that lowers the auger 9, and a left turn that activates the auger 9 to turn left. A left turn command switch 45 for instructing a command, a right turn command switch 46 for instructing a right turn command for causing the auger 9 to turn right, and a movement command for automatically moving the auger 9 to the storage position or the target discharge position. An automatic switch 47 for commanding, a call switch 48 for commanding a call command for ringing the call alarm 16 provided in the control unit 2 of the combine body, and a discharge switch for commanding a grain discharge command for starting the grain discharging operation of the auger 9 49, Stop for instructing a remote stop command for stopping the turning up and down operation of the auger 9 and stopping the grain discharging operation of the auger 9 Switch 50, a power switch 51 for switching the on-off of power supply are provided respectively.

  Each of these switches is configured to be urged to return to an off state so that it is turned on when a finger is pressed and turned off when the finger is released. The power switch 51 is provided with a pilot lamp 52 that lights up when the power is on.

  The wireless remote controller 42 oscillates a signal having a specific frequency that is set differently for each switch when the switch is turned on in response to the operation of each switch for command. A signal transmitter 53 is provided as output control means for transmitting a signal as a radio wave having a constant output via the transmission antenna 54, and a battery 55 for supplying power to them.

  That is, when the lift command switch 43 is pressed and turned on, a lift command is issued by transmitting a radio signal having a frequency corresponding to the lift command, and when the finger is released from the lift command switch 43, the lift command switch 43 is lifted. The transmission of the radio signal having the frequency corresponding to the command is completed, and the ascending command is stopped.

  When the lowering command switch 44 is pressed and turned on, a lowering command is issued by transmitting a radio signal having a frequency corresponding to the lowering command, and when the finger is released from the lowering command switch 44, the lowering command switch 44 is turned off. The transmission of the radio signal of the corresponding frequency is finished, and the descending command is stopped.

  When the left turn command switch 45 is turned on by pushing it with a finger, a left turn command is instructed by transmitting a radio signal having a frequency corresponding to the left turn command, and when the left turn command switch 45 is released and turned off. Then, the transmission of the radio signal having the frequency corresponding to the left turn command is finished, and the left turn command is stopped.

  When the right turn command switch 46 is pressed and turned on with a finger, a right turn command is commanded by transmitting a radio signal having a frequency corresponding to the right turn command, and the right turn command switch 45 When it is turned off, the transmission of the radio signal having the frequency corresponding to the right turn command is finished, and the right turn command is stopped.

  The left turn command switch 45 is provided on the right side facing the front of the wireless remote controller 42, and the right turn command switch 46 is provided on the left side facing the front of the wireless remote control 42, and is displayed on both command switches. The contents of each are opposite to the installation position of each command switch. This is because the turning direction in the right turning operation and the left turning operation is defined based on a reference in which the forward direction of the combine is the 12 o'clock direction, and the turning direction that is turned by each command switch is based on the definition of the turning direction. On the other hand, when the operator who uses the wireless remote controller 42 commands the turning operation of the auger 9 from the front end side of the auger 9 at a position away from the combine main body, the switch is arranged at a position that is easily grasped intuitively. This is because each command switch is arranged so that a turning operation can be commanded by operating.

  When the automatic switch 47 is pressed and turned on, a movement command is issued by transmitting a radio signal having a frequency corresponding to the movement command. When the automatic switch 47 is released and turned off, the movement command is handled. The transmission of the frequency radio signal ends and the movement command stops.

  When the call switch 48 is pressed and turned on, a call command is issued by transmitting a radio signal having a frequency corresponding to the call command. When the call switch 48 is released and turned off, the call command is supported. The transmission of the radio signal with the frequency ends and the calling command is stopped.

  When the discharge switch 49 is pressed and turned on, a radio signal having a frequency corresponding to the grain discharge command is transmitted to instruct the grain discharge command. When the finger is released from the discharge switch 49 and turned off, Transmission of a radio signal having a frequency corresponding to the grain discharge command is terminated, and the grain discharge command is stopped.

  When the stop switch 50 is pressed and turned on, a radio signal having a frequency corresponding to the remote stop command is transmitted to instruct a remote stop command. When the stop switch 50 is released and turned off, the remote stop command is issued. The transmission of the radio signal having the frequency corresponding to the above is terminated and the remote stop command is stopped.

  Thus, the wireless remote controller 42 commands the ascending command, the descending command, the left turn command, the right turn command, the movement command and the grain discharge command as a control command, and the remote stop command as a stop command. As operating means, an ascending command switch 43, a descending command switch 44, a left turn command switch 45, a right turn command switch 46, an automatic switch 47, a discharge switch 49, and a stop switch 50 are provided. A command for turning and raising / lowering 9 and a command for switching from at least the discharge stop state to the grain discharge state are instructed.

  The above commands as the control command and the stop command correspond to a plurality of operation commands of the present invention. Moreover, although mentioned later in detail, in this embodiment, a remote stop command is corresponded to the specific operation command of this invention among these several operation commands.

  The battery 55 and the signal transmitter 53 are connected via a power supply control circuit 56. When the power supply control circuit 56 is in a power supply state, power is supplied from the battery 55 to the signal transmitter 53, and the signal transmitter. 53 is in an operating state and can output a radio signal. However, if the power control circuit 56 is in a power cutoff state, power is not supplied from the battery 55 to the signal transmitter 53, and the signal transmitter 53 is suspended. It will be in a state which cannot output a radio signal. That is, the power supply control circuit 56 functions as an operation state switching unit that switches between an operating state and a hibernation state by intermittently supplying power to the signal transmitter 53.

  As described above, the wireless remote controller 42 includes the signal transmitter 53 as output control means and the power supply control circuit 56 as operation state switching means.

  The power supply control circuit 56 is switched between the power supply state and the power cut-off state by operating the power switch 51 to turn on and off, and issuing an operation command and a pause command. Specifically, when the power control circuit 56 is in the power cut-off state, if the power switch 51 is pressed and held for 0.5 [seconds] or longer, the power control circuit 56 switches to the power supply state, and the power control When the circuit 56 is in the power supply state, if the power switch 51 is pressed and held for 0.5 [seconds] or longer, the power control circuit 56 switches to the power cut-off state. The pilot lamp 52 provided with the power switch 51 is controlled to be turned on and off by the power supply control circuit 56 so that it is turned on when the power is supplied.

  As described above, an operation command and a pause command are commanded by turning on / off the power switch 51, and the power control circuit 56 is configured to switch the signal transmitter 53 between the running state and the sleep mode based on these commands. Has been. Therefore, the power switch 51 functions as an on / off command means.

  Further, the power supply control circuit 56 operates in the operating state of the signal transmitter 53, the ascending command switch 43, the descending command switch 44, the left turn command switch 45, the right turn command switch 46, the automatic switch 47, the call switch 48, and the discharge switch 49. Any of the ascending command, the descending command, the left turn command, the right turn command, the movement command, the grain discharge command, and the remote stop command by entering the no-operation state where none of the stop switches 50 are operated. When the state where no command is issued continues for a set time, the signal transmitter 53 is automatically switched to a sleep state.

  In other words, the signal transmitter 53 executes the no-operation time monitoring process in the operating state, and the above-described no-operation state continues based on the above-described control command and stop command, that is, the presence / absence of the operation command. If the non-operation state continues for the set time (3 minutes in this embodiment), it is determined that the wireless remote controller 42 is not being used, and the power control circuit 56 is turned off. By instructing the power source control circuit 56 to switch to the state, the power source control circuit 56 can switch to the hibernation state based on the command commanded by itself.

  According to the configuration as described above, the signal transmitter is automatically generated even when the operator consciously turns off the power switch 51 and also when no operation state is operated for 3 minutes without any operation switch being operated. 53 can be switched to a dormant state, and when the wireless remote controller 42 is not operated, the auger 9 can be prevented from operating unexpectedly due to an erroneous operation, and power saving of the wireless remote controller 42 can be achieved. it can.

  In addition, when the stop switch 50 is pressed, the wireless remote controller 42 is configured to output a control signal for switching to the power supply state to the power supply control circuit 56 in addition to the control signal for the signal transmitter 53. Yes. As a result, the power supply control circuit 56 switches to the power supply state when the stop switch 50 is pushed and operated without turning on the power switch 51 in the power cut-off state.

  In other words, when the power transmitter circuit 56 is in the power cut-off state and the signal transmitter 53 is in the inactive state, when the remote stop command is commanded by the stop switch 50, the power source control circuit 56 is switched to the power supply state. Instead, the signal transmitter 53 is switched to the operating state. In this way, the power supply control circuit 56 of the wireless remote controller 42 switches the signal transmitter 53 to the operating state when a remote stop command is commanded by the stop switch 50 when the signal transmitter 53 is in the inactive state. It is configured. Therefore, the remote stop command corresponds to the specific operation command of the present invention.

  With this configuration, it is necessary to urgently stop the operation of the auger 9 after the power switch 51 is turned off or there is no operation time of 3 minutes and the power control circuit 56 is in a power cut-off state. In this case, the radio signal corresponding to the remote stop command is operated by suddenly operating the stop switch 50 without performing a troublesome operation such as instructing the remote stop command with the stop switch 50 after the power switch 51 is turned on. Can be output.

  As shown in FIG. 1 and FIG. 2, a receiving antenna 57 and a receiver 58 for receiving a radio signal by radio waves transmitted from the radio remote controller 42 are provided in the vicinity of the operation unit 20 of the combine main body. A signal processing device 59 (see FIG. 5) is provided for discriminating which command information the received signal is according to the reception frequency and converting it into a control signal corresponding to the command information.

  And the command information transmitted from the wireless remote controller 42 is input to the control device H of the combine main body via the signal processing device 59, and the control device H is supplied from the operation unit 20 of the combine main body. In addition to the command, based on the command from the wireless remote controller 42, the operation of the lifting hydraulic cylinder 15, the swing motor M2, the clutch motor M1, and the calling alarm 16 is controlled.

  That is, when an ascending command is commanded by the ascending command switch 43, the control device H operates the ascending / descending hydraulic cylinder 15 to the ascending side and operates the descending command switch 44 for the descending command. When commanded, the raising / lowering hydraulic cylinder 15 is actuated downward in order to lower the auger 9, and when the left turning command is commanded by the left turning command switch 45, the auger 9 is turned left. When the turning motor M2 is operated to the left turning side and the right turning command is commanded by the right turning command switch 46, the turning motor M2 is operated to the right turning side in order to operate the auger 9 to turn right. .

  Further, when the movement command is instructed by the automatic switch 47, the control device H determines whether or not the auger 9 is located at the storage position based on detection information such as the turning position detection sensor Ry. When the remote stop command is instructed by the stop switch 50 in order to automatically move the auger 9 to the storage position or the target discharge position according to the position of 9, the turning operation and the various operations of the auger 9 are stopped. Accordingly, the operation of the lifting hydraulic cylinder 15 and the swing motor M2 is controlled.

  That is, when the automatic switch 47 is pushed and a movement command is issued, the control device H, when the auger 9 is in the storage position, moves the lifting hydraulic cylinder to move the auger 9 to the target discharge position. 15 and the swing motor M2 are operated, and when the auger 9 is located at the discharge position, the lifting hydraulic cylinder 15 and the swing motor M2 are operated and the stop switch 50 is pushed to move the auger 9 to the retracted position. When the remote stop command is issued, the lifting hydraulic cylinder 15 and the swing motor M2 are stopped to stop the swing operation and the lift operation of the auger 9.

  Further, the control device H is configured to turn the auger 9 into a grain discharge state when a grain discharge command is commanded, and to set the auger 9 into a discharge stop state when a remote stop command is commanded. It is configured to control the operation of the motor M1.

  That is, when the discharge switch 49 is pushed and a grain discharge command is instructed, the control device H drives the clutch motor M1 in the forward rotation direction to bring the auger 9 into the grain discharge state, and the stop switch 50. Is pressed and a discharge stop command is issued, the clutch motor M1 is driven in the reverse direction to put the auger 9 in the discharge stop state.

  Furthermore, the control device H is configured to control the operation of the call alarm 16 so as to sound the call alarm 16 when a call command is issued. That is, the control device H sounds the call alarm 16 when a call command is instructed by the call switch 48.

  As described above, the wireless operation device includes the wireless remote controller 42 and the command means on the combine body side including the operation lever 20A, the automatic switch 21, the stop switch 22, and the clutch on / off switch 24. In addition, since a control command and a stop command can be commanded from the command means on the combine body side, when two or more workers work together using the combine, the command from the wireless remote controller 42 and the combine body side In some cases, a command from the command means is simultaneously commanded to the control device H. In such a case, as will be described below, the control device H basically processes the command from the wireless remote controller 42 with priority, and from the command means on the combine body side, the movement stop command and the discharge stop command. When the command is issued, the command from the command means on the airframe side is preferentially processed.

  In other words, when the stop command is instructed by one of the wireless remote controller 42 or the command means on the combine body side and the control command is instructed by the other, the control device H gives priority to the stop command and turns the auger 9 up and down. And when the control command is instructed from both the wireless remote controller 42 and the command means on the combine body side, the operation of the auger 9 is given priority over the control command of the wireless remote controller 42. Is configured to control.

  The control of the turning up and down operation of the auger 9 by the control device H configured as described above will be described with a specific example.

  When the auger 9 is swung up and down by various swivel lift commands commanded by tilting the operation lever 20A on the combine body side, the ascending command switch 43, the descent command switch 44, the left swivel command of the wireless remote controller 42 are operated. When a turning up / down command different from that commanded from the combine main body side is commanded by the switch 45 and the right turn command switch 46, the auger 9 is in a state where the turning up / down command is commanded from the wireless remote controller 42. However, when the turning up / down command is interrupted according to the turning up / down command from the wireless remote controller 42, the turning up / down operation is performed according to the turning up / down command from the combine body side. If the turning up / down command from the combine main body is not issued until the turning up / down command from the wireless remote control 42 is interrupted, the turning up / down operation of the auger 9 is performed when the turning up / down command from the wireless remote control 42 is stopped. Stops.

  Then, when the auger 9 is swung up and down by various swivel lifting commands commanded by tilting the operation lever 20A on the combine body side, a remote stop command is commanded by the stop switch 50 of the wireless remote controller 42. Then, the turning up / down operation of the auger 9 is stopped while the remote stop command is instructed, and when the remote stop command is interrupted, the turning up / down operation of the auger 9 is resumed. Similarly, when the auger 9 is turning up and down by various turning up / down commands issued by the ascending command switch 43, the down command switch 44, the left turn command switch 45, and the right turn command switch 46 of the wireless remote controller 42. In addition, when a movement stop command is instructed by the stop switch 22 on the combine body side, the turning up and down operation of the auger 9 is stopped while the movement stop command is instructed, and when the movement stop command is interrupted, The revolving motion is resumed. In the former case, if the turning up / down command from the combine main body is no longer commanded before the remote stop command from the wireless remote controller 42 is interrupted, the auger is stopped even if the remote stop command from the wireless remote controller 42 is interrupted. Naturally, 9 remains stopped. The same applies to the latter.

  Further, when the auger 9 is turning up and down by various turning up and down commands commanded by the ascending command switch 43, the descending command switch 44, the left turn command switch 45, and the right turn command switch 46 of the wireless remote controller 42. Even if a turning up / down command different from that commanded from the wireless remote controller 42 is instructed by the tilting operation of the operation lever 20A on the combine body side, the auger 9 performs the turning up / down operation according to the turning up / down command from the wireless remote control 42. Continue.

  In addition, when the clutch on / off switch 24 on the combine body side is switched from the off position to the on position, the grain discharge command is instructed and the radio remote controller 42 is stopped after the auger 9 enters the grain discharge state. When the remote stop command is instructed by the switch 50, the auger 9 is switched to the discharge stop state, and the auger 9 is in the discharge stop state even when the clutch on / off switch 24 on the combine body side is in the on position. Then, a new grain discharge command is issued by returning the clutch on / off switch 24 on the combine body side to the OFF position and switching it back to the ON position, or by pressing the discharge switch 49 of the wireless remote controller 42. Unless this is done, the auger 9 is maintained in the discharge stopped state.

  When a movement command is commanded by the automatic switch 21 on the combine body side and the auger 9 is automatically moved to the storage position or the target discharge position, a remote stop command is issued by the stop switch 50 of the wireless remote controller 42. Is stopped, the movement of the auger 9 to the storage position or the target discharge position is stopped, and the swivel raising / lowering operation of the auger 9 is stopped unless a new control command is issued from the combine main body side or the wireless remote controller 42. Similarly, when a movement command is instructed by the automatic switch 47 of the wireless remote controller 42 and the auger 9 is automatically moved to the storage position or the target discharge position, the movement is stopped by the stop switch 22 on the combine body side. When the command is commanded, the movement of the auger 9 to the storage position or the target discharge position is stopped, and the turning up and down operation of the auger 9 is stopped until a new control command is commanded from the combine main body side or the wireless remote controller 42.
