Description

  In the present invention, the combine main body is provided with a grain discharging auger and a control means for controlling the operation of the grain discharging auger, and an operation command for the grain discharging auger is commanded to the control means by a radio signal. The present invention relates to a wireless operating device for a grain discharging auger in a combine equipped with a manually operated wireless command means.

  The combine having such a configuration can perform the grain discharging operation of discharging the grain harvested by the harvesting operation in the field to the loading platform of a transport vehicle located on the ridge by the grain discharging auger, for example. However, when performing such a grain discharging operation, an operator who performs a steering operation for traveling at the control unit of the aircraft is in a position for discharging the aircraft from the cutting work location. After moving to, while commanding by the wireless command means of the wireless operation device of the grain discharge auger and operating the turning actuator and the lifting actuator, while turning and lifting the grain discharging auger, The grain outlet at the tip is moved onto the loading platform of the transport vehicle, and the grain is discharged by switching to the grain discharging state by the discharging actuator.

  And, when performing the grain discharge work by the grain discharge auger, for example, in order to level the amount of stored grain inside the loading platform of the transport vehicle, the discharge position of the grain discharge port on the auger tip side There is a case where a fine adjustment operation is performed to move a little by little. In addition, at the start or end of the grain discharging operation, the posture is changed to the discharging posture in which the turning posture of the grain discharging auger is set in advance, or to the retracted posture that is the posture at the time of cutting or running In order to do this, a turning start command is instructed by the wireless command means, the grain discharging auger is automatically turned, and the turning operation is automatically performed to the target position.

  As a conventional technique of the wireless operation device for the grain discharging auger having the above-described configuration, for example, as described in Patent Document 1, an operation command instructed by a wireless signal by a manually operated wireless command means Rotating and turning operation of the grain discharging auger, switching operation between the grain discharging state and the discharging stop state, starting operation of the automatic turning operation to the target position of the grain discharging auger, and arbitrary during the automatic turning operation There is a wireless operating device for a grain discharging auger configured to perform various operations of the grain discharging auger such as a stop operation.

  The wireless operating device for the grain discharging auger described in Patent Literature 1 is for the grain discharging by the wireless command means turning on the command operating tool that is biased back to the OFF state by manual operation. An operation command for the auger is input, and a radio signal having a frequency corresponding to the input operation command is transmitted. A radio signal wirelessly transmitted from the wireless command unit is received and transmitted to the control unit. For this purpose, a receiving antenna is provided on the main unit side of the combine.

  However, for the device that outputs a radio signal, the power of the radio signal that can be output is restricted by the regulations of the Radio Law, so the power of the output radio signal is also limited in the wireless command means of Patent Document 1. It is kept within range. Accordingly, when the distance between the receiving antenna and the wireless command means becomes long, or when an obstacle occurs in the space between the receiving antenna and the wireless command means, the wireless command means outputs the wireless In some cases, the signal cannot be properly received by the receiving antenna, and the wireless command means and the control means cannot communicate. When the wireless command means and the control means cannot communicate with each other, the operation command input by the wireless command means is not transmitted to the control means, and the operator thinks about various operations of the grain discharging auger. It will not be possible.

  As described above, the operation of the auger for grain discharge by the wireless command means includes the up / down turning operation, the switching operation between the grain discharging state and the discharging stop state, and the automatic turning operation to the target position of the grain discharging auger. Start operation, and arbitrary stop operation during automatic turning operation, etc., of these, the up / down turning operation is continuously performed while the up / down turning command is commanded by the wireless command means And a turning actuator is operated to move the grain discharging auger up and down. Then, the switching operation between the grain discharging state and the discharging stop state and the starting operation of the automatic turning operation to the target position of the grain discharging auger are once instructed. Even if the operation is not continued, the corresponding actuator is automatically continuously operated until the discharge state switching operation and the automatic turning operation to the target position are completed.

  Therefore, during the grain discharging operation, when the wireless command means and the control means become incapable of communication as described above, the wireless command means is switched to switch the kernel discharging auger in the discharging state to the discharging stop state. Even if a discharge stop command is issued, the command is not transmitted to the control means, and the grain discharge auger may remain in the discharged state. As a result, when the stored amount of the grain inside the loading platform of the transport vehicle reaches the upper loading limit due to the grain discharged from the discharged grain auger, the grain discharge is temporarily stopped. However, there is a possibility that the inconvenience that the grain discharging auger cannot be switched to the discharging stop state may occur.

  In addition, since the operation command input by the wireless command means is not transmitted to the control means, a turning stop command is issued to stop the grain discharging auger during the automatic turning operation of the grain discharging auger. Even if the command is issued, the grain discharging auger still continues the turning operation, and there is a concern that the grain discharging auger during the automatic turning operation cannot be stopped.

  Therefore, in view of the above circumstances, the present invention has the disadvantage that the grain discharge auger cannot be switched to the discharge stop state when the wireless command means and the control means become incapable of communication, and the grain during the automatic turning operation. An object of the present invention is to provide a wireless operating device for a grain discharging auger in a combine that can avoid the inconvenience that the grain discharging auger cannot be stopped.

The operation command codes are a plurality of types of command codes that are set differently for each switch when the switch is turned on in response to the operation of each switch for operation commands. The transmission permission command is a control command for permitting the transmission unit 53s to transmit a radio signal, and the transmission prohibition command is a control command for prohibiting the transmission unit 53s from transmitting a radio signal. Although the turning completion information will be described in detail later, when the auger 9 that performs the automatic turning operation by the automatic turning command reaches the target position, the turning operation of the auger 9 automatically stops, or a turning stop command is commanded. Thus, when the turning operation is stopped based on the operator's intention, the control device H on the machine body transmits information as discharge position movement completion information. The transmission unit 53s transmits the carrier wave as a constant-output radio wave when a transmission permission command is issued from the control unit 53c, and modulates the carrier wave based on this when the control unit 53c outputs an operation command code. The modulated wave is transmitted. The receiving unit 53r receives a radio signal transmitted from the control device H on the airframe side.

  Hereinafter, the operation of the wireless operation device 42 after the power switch 56 is turned on will be specifically described based on the flowchart of the control program of the wireless operation device processed in the control unit 53c shown in FIG.

  When the power switch 56 is turned on to supply power to the wireless operation device 42, the control program of the wireless operation device 42 is repeatedly executed at predetermined operation cycles in the control unit 53 c of the signal transmission / reception circuit 53. In the control unit 53c immediately after power is supplied to the wireless operation device 42, a transmission permission command for the transmission unit 53s is written to the input / output port I / O (step # 1), and an operation command code is written. In this state, input / output of the port is performed as it is, and a carrier wave that is not modulated is transmitted from the transmission unit 53 c as a radio signal via the transmission / reception antenna 54. Accordingly, a carrier wave is output immediately after the power switch 56 of the wireless operation device 42 is turned on.

  Thereafter, when an operation command is issued (step # 2), an operation command code corresponding to each operation command is written to the input / output port I / O (step # 3) and output to the transmission unit 53s (step #). 9). When the operation command is issued, the count of the timer for non-operation state timing is cleared (step # 4). Thereafter, if the non-operation state does not continue for the set time (3 minutes in this embodiment) (step # 5), the timer count is incremented (step # 10).

  When the non-operation state continues for the set time (step # 5), that is, when no operation command is transmitted for the set time, the discharge state flag is checked (step # 6) and the automatic turning flag is checked (step #) 7) If neither flag is set, the transmission permission command written in step # 1 held by the input / output port I / O is overwritten and changed to the transmission prohibition command (step # 8). Information held by the port I / O is output to the transmission unit 53s (step # 9).

  The discharge state flag is set in step # 3 when a discharge start command is commanded, and is cleared in step # 3 when a discharge stop command is commanded. Therefore, the discharge state flag is set until the discharge stop command is issued after the discharge start command is issued. The automatic turning flag is set in step # 3 when an automatic turning command is commanded, and is cleared in step # 3 when a movement stop command is commanded. Further, the automatic turning flag is also cleared when the receiving unit 53r receives turning completion information from the control device H on the airframe side. Therefore, the automatic turning flag is set until the movement stop command is issued or the turning completion information is received after the automatic turning command is issued.

  As described above, unless a discharge start command or an automatic turning command is transmitted, if a state in which the operation command is not transmitted continues for a predetermined time after the operation command is transmitted, the transmission of the carrier wave is stopped. Power consumption is reduced and consumption of the battery 55 is reduced.

  The specific operation of the wireless operation device 42 described above will be described by applying each switch. When the discharge switch 49 is pressed and turned on with a finger, a discharge start command modulation wave corresponding to the discharge start command is transmitted, so that a discharge operation is commanded. Thus, the transmission of the modulated wave for the discharge start command ends. Thereby, the auger 9 can be made into a grain discharge state. Then, after a modulated wave corresponding to the discharge start command is transmitted, an unmodulated carrier wave as a monitoring radio signal is transmitted.

  When the discharge stop switch 50 is turned on by pushing it with a finger, a modulation wave for a discharge stop command corresponding to the discharge stop command is transmitted, a discharge stop operation is commanded, and when the finger is released from the discharge stop switch 50, it is turned off. Thus, the transmission of the modulation wave for the discharge stop command ends. As a result, the auger 9 can be brought into a discharge stop state. Then, after the modulated wave corresponding to the discharge stop command is transmitted, the unmodulated carrier wave is transmitted again, and when the non-operation state continues for the set time as described above, the carrier wave transmission is stopped.

  When the automatic switch 47 is pressed and turned on, a modulated wave for automatic turning command corresponding to the automatic turning command is transmitted, and an automatic turning operation is commanded. When the automatic switch 47 is released and turned off, the automatic switch 47 is turned off. Then, the transmission of the modulated wave for the automatic turning command ends. Then, after the modulated wave corresponding to the automatic turning command is transmitted, an unmodulated carrier wave as a monitoring radio signal is transmitted.

  When the turning stop switch 48 is pressed and turned on with a finger, a turning stop command modulation wave corresponding to the turning stop command is transmitted to instruct a turning stop operation, and the turning stop switch 48 is released. When turned off, the transmission of the modulation wave for turning stop command ends. Then, after the modulated wave corresponding to the turning stop command is transmitted, the unmodulated carrier wave is transmitted again, and when the non-operation state continues for the set time as described above, the transmission of the carrier wave is stopped.

  When the auger 9 completes the movement to the target position without commanding the turning stop command, discharge position movement completion information indicating that the movement is completed is transmitted from the control device H described later, Based on this, the carrier wave as the monitoring radio signal that has been transmitted until then is not transmitted. Therefore, the carrier wave as the monitoring radio signal is not generated until the pushing operation of the turning stop switch 48 is started after the pushing operation of the automatic switch 47 is completed or until the discharge position movement completion information described later is received. It will be transmitted continuously.

When the lift command switch 43 is turned on by pushing it with a finger, the start of the lift operation is commanded by transmitting a modulation wave for the lift command corresponding to the lift command, and when the finger is released from the lift command switch 43 and turned off. Then, the transmission of the modulation wave for the ascending command is completed, and the stop of the ascending operation is commanded.
When the descent command switch 44 is pressed and turned on, a modulation wave for a descent command corresponding to the descent command is transmitted to command the start of the descent operation. When the descent command switch 44 is released and turned off, the descent command switch 44 is lowered. The transmission of the command modulation wave is finished, and the stop of the lowering operation is commanded.

When the left turn command switch 45 is pressed and turned on with a finger, a left turn command modulation wave corresponding to the left turn command is transmitted to instruct the start of the left turn operation. When the button is released and turned off, the transmission of the modulation signal for the left turn command is completed, and the stop of the left turn operation is commanded.
When the right turn command switch 46 is pressed and turned on with a finger, a right turn command modulation wave corresponding to the right turn command is transmitted to start the right turn operation, and the right turn command switch When the finger is released from 46 and turned off, the transmission of the modulated wave for the right turn command is terminated and the stop of the right turn operation is commanded.

When the extension command switch 51 is pressed and turned on, a decompression command modulation wave corresponding to the extension command is transmitted to instruct the start of the extension operation, and when the extension command switch 51 is released and turned off. Then, the transmission of the modulation wave for the extension command is finished, and the stop of the extension operation is instructed.
When the shortening command switch 52 is pressed and turned on, a shortening command modulation wave corresponding to the shortening command is transmitted to start the shortening operation. When the shortening command switch 52 is released and turned off, the shortening command switch 52 is shortened. The transmission of the command modulation wave is finished, and the stop of the shortening operation is commanded.

  As shown in FIGS. 1 and 2, the airframe is provided with a transmitting / receiving antenna 57 and a transmitter / receiver 58, and can receive a radio signal by radio waves transmitted from the wireless operation device 42. The control device H can transmit information to the wireless operation device 42 by a wireless signal. A signal processing device 59 is provided between the transceiver 58 and the control device H. The signal processing device 59 demodulates the signal received by the transceiver 58 to obtain an operation command from the received signal, and the operation command Is converted into a corresponding control signal and output to the control device H, and a signal indicating turning completion information as discharge position movement completion information transmitted from the control device H to the wireless operation device 42 is acquired from the control device. A signal corresponding to this is output to the transceiver 58.

  As shown in FIG. 9, a control device H using a microcomputer is used. The control device H includes a turning position detection sensor Ry, an upper limit switch 14, and command switches SU <b> 1 of the operation unit 20 on the airframe side. Each signal of SD1, SL1, SR1, automatic switch 21, stop switch 22, discharge position setting volume 23, and clutch on / off switch 24 is input through an electric wire, and is configured to execute control corresponding to the operation of each command switch. Has been.

  The control device H is configured to receive an operation command transmitted from the wireless operation device 42 via the signal processing device 59. Hereinafter, the operation of the control device H regarding the turning operation, the raising / lowering operation, the telescopic operation, the switching operation of the discharge clutch 13, the automatic turning operation, and the automatic turning stop operation based on the operation command from the wireless operation device 42 will be specifically described. To do.

  The control device H executes an operation corresponding to each operation command based on the operation command commanded from each switch. That is, when the operation command is commanded by the ascending command switch 43, the descending command switch 44, the right turn command switch 46, the left turn command switch 45, the extension command switch 51, and the shortening command switch 52, the period during which the operation is on In the meantime, the controller H continuously operates the actuator corresponding to each operation so as to continue the operation corresponding to each operation command.

  That is, when the lift command switch 43 is turned on and a lift command is commanded, the lift operation of the auger 9 is executed by the lift hydraulic cylinder 15, and when the lift command switch 43 is turned off and the lift command is not commanded. When the lifting operation by the lifting hydraulic cylinder 15 is stopped and the lowering command switch 44 is turned on and the lowering command is commanded, the lowering operation switch 44 performs the lowering operation of the auger 9 and the lowering command switch 44 is turned off. When operated and no lowering command is issued, the lowering operation by the lifting hydraulic cylinder 15 is stopped.

  When the right turn command switch 46 is turned on and the right turn command is issued, the right turn command of the auger by the turning motor M3 is executed, and the right turn command switch 46 is turned off and the right turn command is issued. Is no longer commanded, the right turning operation by the turning motor M3 is stopped, and when the left turning command switch 45 is turned on and the left turning command is issued, the left turning operation of the auger by the turning motor M3 is executed. When the turn command switch 45 is turned off and no left turn command is issued, the left turn operation by the turn motor M3 is stopped.

  When the extension command switch 51 is turned on and the extension command is instructed, the extension operation of the auger 9 is executed by the extension motor M1, and when the extension command switch 51 is turned off and the extension command is not instructed, the extension motor M1 When the shortening command switch 52 is turned on and the shortening command is instructed, the shortening operation of the auger 9 is executed by the telescopic motor M1, and the shortening command switch 52 is turned off and the shortening command is instructed. When it disappears, the shortening operation by the extension motor M1 is stopped.

  When an operation command is instructed by the automatic switch 47, the turning stop switch 48, the discharge switch 49, and the discharge stop switch 50, each of these switches functions as a trigger switch. The control device H controls the actuator corresponding to each operation so as to perform the operation corresponding to.

  That is, when the discharge switch 49 is turned on and a grain discharge command is issued, the clutch motor M2 performs an operation for switching the discharge clutch 13 to the engaged state, and the auger 9 is switched to the grain discharge state. When the discharge stop switch 50 is turned on and a discharge stop command is issued, the switching operation of the discharge clutch 13 to the disengagement state by the clutch motor M2 is executed, and the auger 9 is switched to the discharge stop state. When the automatic switch 47 is turned on and an automatic turning command is issued, the turning operation to the target position of the auger 9 by the turning motor M3 is executed, and the turning operation of the auger 9 is continued. When the turning stop switch 48 is turned on and a turning stop command is issued, the turning operation of the auger 9 to the target position by the turning motor M3 is stopped, and the turning operation of the auger 9 is stopped.

  Further, the control device H communicates with the wireless operation device 42 when an operation command is commanded by the discharge switch 49 and the automatic switch 47, that is, when a discharge start command and an automatic turning command are commanded. Configured to monitor status.

  When the discharge start command is instructed by the discharge switch 49, the control device H is instructed until the discharge stop command is instructed by the discharge stop switch 50, or when the automatic turning command is instructed by the automatic switch 47. Until the turning stop command is instructed by the turning stop switch 48 or until the auger 9 moves to the target position, the communication state with the wireless operation device is monitored, and the monitoring is transmitted from the wireless operation device 42. If a state in which a carrier wave as a radio signal cannot be received continues for a predetermined time or longer, it is determined that communication is impossible, and even if a discharge stop command or a turn stop command from the wireless operation device 42 is not commanded, a discharge stop operation or a turn stop Perform the operation.

  The operation of the control device H will be described below based on the flowchart of the auger operation control program executed in the control device H. As shown in FIGS. 11 and 12, when it is determined at step # 1 that the operation command has been issued, the control device H determines the commanded operation command at steps # 2 to # 10. If it is determined that the operation command commanded in step # 2 is a discharge start command, the clutch motor M2 is operated for a predetermined time to switch the operating auger 9 to the grain discharge state (step # 11), and the discharge state flag Is set (step # 12). If it is determined that the operation command instructed in step # 3 is an automatic turning command, the turning motor M3 is operated to automatically turn the auger 9 (step # 13), and the automatic turning flag is set (step #). 14). If it is determined that the operation command instructed in step 4 is the discharge stop command, the clutch motor M2 is operated for a predetermined time to switch the auger 9 to the discharge stop state (step # 15), and the discharge state flag is cleared. (Step # 16). If it is determined that the operation command instructed in Step # 5 is a turning stop command, the turning motor M3 is stopped (Step # 17), the automatic turning operation of the auger 9 is stopped, and the automatic turning flag is cleared ( Step # 18). If it is determined that the operation command instructed in step # 6 is a lift command, the lifting hydraulic cylinder 15 is operated to lift the auger 9 (step # 19). If it is determined that the operation command instructed in step # 7 is a lowering command, the lifting hydraulic cylinder 15 is operated to lower the auger 9 (step # 20). If it is determined that the operation command instructed in step # 8 is a left turn command, the turn motor M3 is operated to turn the auger 9 left (step # 21). If it is determined that the operation command instructed in step # 9 is a right turn command, the turn motor M3 is operated to turn the auger 9 to the right (step # 22). If it is determined that the operation command instructed in step # 10 is an expansion / contraction command, the expansion motor M1 is operated to expand / contract the auger 9 (step # 23). If the commanded operation command is a shortening command, the telescopic motor M1 is actuated to shorten the auger 9 (step # 24).

  Then, when the operation command is not operated, the control device H determines whether or not the automatic turning is being performed and whether or not the grain is being discharged based on the discharge state flag and the automatic turn flag, respectively (step #). 25, step # 26), if none of them applies, the operation of the lifting hydraulic cylinder 15, the turning motor M3, and the telescopic motor M1 is stopped (step # 27). If automatic turning is in progress, the drive of the turning motor is continued (step # 28), and the presence or absence of a carrier wave is checked until the auger 9 moves to the target position (step # 29, step # 30). If it is in the discharge state, the presence or absence of a carrier wave is checked as it is (step # 26, step # 30).

  The carrier wave to be checked here is transmitted from the wireless operation device 42 as a monitoring radio signal. Depending on the radio wave condition, the carrier wave may be momentarily interrupted, but the control device H is in a state where the carrier wave is interrupted. The configuration is such that the forced operation of the operation of the auger 9 is performed when it continues for a set time (500 [ms] in this embodiment) or longer. That is, if it is determined in step # 31 that the carrier wave cannot be received for a set time, if the auger 9 is turning (determined in step # 32 by the automatic turning flag as described above), the auger 9 The same processing as that executed when the turn to the target position is completed is executed. That is, the turning motor M3 is stopped (step # 37), turning completion information is transmitted to the wireless operation device 42 (step # 38), and the automatic turning flag is cleared (step # 39). If it is in the grain discharge state, it is switched to the discharge stop state (step # 33), and the grain discharge flag is cleared (step # 34).

  As described above, when the grain discharge auger 9 is in the grain discharge state and in the automatic turning operation, if the state in which the carrier wave as the monitoring radio signal is not received continues for a predetermined time, the grain discharge state Is switched to the discharge stop state, and when the automatic turning operation is being performed, the automatic turning operation is stopped. Therefore, communication between the wireless operation device 42 and the control device H on the machine body becomes impossible, and the auger 9 in the grain discharge state cannot be switched to the discharge stop state, or the auger 9 during automatic turning is stopped halfway. It is possible to prevent inconvenience caused by the fact that it cannot be performed.
