The right ramp 14R in the front and rear middle part is a right middle turn signal arranged on the right side of the traveling body 2. The middle right turn signal is formed on the right side of the traveling machine body 2 and is adjacent to the engine cover 19 covering the right side of the engine room accommodating the engine on the left and right sides.

  The left and right lamps 16L and 16R on the rear side are a left rear turn signal disposed on a left side portion of a rear end portion of an upper surface of the traveling body 3 and a right rear turn signal disposed on a right side portion.

  In the present combine, the exhaust gas discharged from the engine is discharged backward from the rear end of the traveling body 2 or upward or obliquely upward from the rear position of the control section 7 of the traveling body 2. This exhaust gas contains particulates (fine solids) such as soot. DPF (registered trademark), which is a capture filter for removing the particulates from the exhaust gas, is provided in the middle of the exhaust gas discharge path.

  The DPF has a case and a filter main body provided inside the case. The exhaust gas is introduced into the case, and the particulates are captured by the filter body, and are led out of the case in a clean state. If a large amount of deposits such as particulates adhere to the filter body, clogging occurs and various problems occur, including a decrease in the supplemental function.

  For this reason, the combine is provided with a regenerating means for heating and removing the deposits attached to the DPF (specifically, the filter body) by the exhaust gas from the engine. Specifically, the regenerating means is constituted by an engine control microcomputer 21 (see FIG. 6) which precisely performs various operations of the engine. More specifically, the engine control microcomputer 21 operates the engine so as to discharge high-temperature exhaust gas, thereby performing regeneration control for burning the deposits attached to the filter body of the DPF.

  Incidentally, the combine is configured to be able to execute an automatic regeneration control for automatically performing the regeneration control under a predetermined condition and a manual regeneration control for executing the regeneration control by a manual operation of an operator under a predetermined condition. Have been.

  While the automatic regeneration control is being executed, the regeneration control is performed under the condition that the amount of deposits adhering to the filter main body is equal to or greater than a predetermined value, and the traveling is performed while cutting and threshing work. Automatically executed.

  FIG. 5 is a plan view showing the configuration of the control unit. The control section 7 is formed at a low position between the seat 22 on which the operator sits, a front operation panel 23 disposed in front of the operator sitting on the seat 22, and the seat 22 and the front operation panel 23. It includes a floor step 24 and a side operation panel 26 arranged beside an operator sitting on the seat.

  The front operation panel 23 is provided with a multi-lever 27 and a display panel 28 for displaying various information. The multi-lever 27 performs a steering operation of the traveling machine body 2 by swinging left and right, and performs a lifting operation of the pre-processing unit 3 by swinging back and forth. The display panel 28 includes a speed meter 28a that indicates the traveling speed of the traveling machine body 2, a fir storage amount display lamp 28b that is a storage amount display unit that displays the storage amount of grains (mainly paddy) in the Glen tank 6, A DPF indicator lamp 28c which is a status display unit for displaying the status of the DPF.

  The side operation panel 26 includes a main shift lever 29 as a shift operation tool for performing a traveling shift operation, a DPF manual regeneration switch 31 as a manual operation tool for performing a manual operation for starting the execution of the regeneration control, and a DPF regeneration control. A notification execution switch 32, which is a switching operation tool for switching whether or not to notify that the process is being executed, an engine rotation dial 33, and a cutting / de-powering clutch switch 34 are provided.

  The DPF manual regeneration switch 31 is configured to be capable of an on / off operation. The manual regeneration control is repeatedly executed after the engine is started or after the power is turned on. However, during the execution of the manual regeneration control, the DPF manual regeneration switch 31 must be turned on under predetermined conditions described later. Thus, the reproduction control is started.

  The notification execution switch 32 is configured to be able to be turned on and off.

  The engine rotation dial 33 performs an ON / OFF operation of automatic rotation speed control for automatically controlling the rotation speed of the engine, and performs a manual setting operation of the engine rotation speed when the automatic rotation speed control is OFF.

  The mowing / de-powering clutch switch 34 is a seesaw switch that can be switched between three postures: a posture inclined to one end side, a horizontal posture along the surface of the side operation panel 26, and a posture inclined to the other end side. is there. By switching the three positions of the cutting / de-powering clutch switch 34, a stop state in which the work clutch and the cutting clutch are disconnected, a threshing state in which the working clutch is connected and the cutting clutch is disconnected, and a work clutch And a cutting state in which the cutting clutch is connected.

  In the stop state, the driving of the preprocessing unit 3 and the threshing device 4 is stopped. In the threshing state, the driving of the pre-processing unit 3 is stopped and the threshing device 4 is driven. During the mowing operation, the pre-processing unit 3 and the threshing device 4 are driven. In other words, the mowing / de-powering clutch switch 34 functions as a mowing drive detecting means for detecting whether the pre-processing unit 3 is driven, and also functions as a threshing drive detecting means for detecting whether the threshing device 4 is driven. .

  The automatic regeneration control and the manual regeneration control are performed by a control unit 36 (see FIG. 6) composed of a main microcomputer connected to the engine control microcomputer 21 via a network such as CAN so as to be able to input and output. It is configured to be executable.

  FIG. 6 is a block diagram showing the configuration of the control unit. On the input side of the control unit 36 of the control unit 36, the presence / absence and traveling speed of the traveling body 2 are detected by detecting the operating positions of the DPF pressure sensor 37, the engine rotation dial 33, and the main shift lever 29. Of the main shift lever potentiometer 38, which is a traveling detecting means, the cutting / de-powering clutch switch 34, the DPF manual regeneration switch 31, the notification execution switch 32, and the grain (mainly paddy) in the Glen tank 6. A direction indicator (fir storage amount sensor 39) which is a storage amount detection means for detecting the storage amount in a stepless manner or in one or more stages, and a direction instructing device for performing a direction instructing operation by left and right turn signals 13L, 13R, 14L, 14R, 16L, 16R ( (Not shown) is connected to a turn signal switch 40, which is a direction indication detecting means for detecting the operation of the user.

  The DPF pressure sensor 37 detects the pressure difference between the introduction side and the discharge side of the exhaust gas of the DPF, or detects the pressure on the introduction side, thereby detecting the state of the DPF (specifically, adhering to the filter body). This is a state detecting means for detecting the amount of deposited foreign matter). Incidentally, the state of the DPF can be displayed on the DPF indicator lamp 28c by a predetermined operation.

  The state of the DPF may be set in a plurality of stages depending on the amount of deposits. For example, a state in which the amount of deposits on the filter body is 0 or a minimum is defined as a regeneration unnecessary level at which regeneration control is unnecessary. Further, a state in which the amount of deposits on the filter main body becomes larger than the regeneration unnecessary level is defined as an automatic regeneration enabled level at which the regeneration control can be automatically executed by the automatic regeneration control. In addition, a state in which the amount of deposits on the filter body becomes larger than the automatic regeneration enabled level is defined as a manual regeneration enabled level at which regeneration control can be executed by manual regeneration control. Further, a state in which the amount of deposits on the filter main body becomes larger than the manual regeneration enabled level is defined as a manual regeneration required level at which it is necessary to execute regeneration control by manual regeneration control. Further, the state in which the amount of deposits deposited on the filter body is the maximum is defined as a non-regeneration level at which regeneration control cannot be performed and DPF needs to be replaced.

  On the output side of the control unit 36 of the control unit 36, the DPF indicator lamp 28c, the six lamps 13L, 13R, 14L, 14R, 16L, 16R installed around the traveling body 2, and the fir storage amount The display lamp 28b is connected to a buzzer 41 which is a notifying means for notifying a person or an operator around the present combine by sound.

  The control unit 36 can execute the automatic regeneration control and the manual regeneration control by the engine control microcomputer 21 as described above, and also controls the lamps 13L, 13R, 14L, 14R, 16L, 16R, which are surrounding notification means. The used well-known notification control can also be executed.

  FIG. 7 is a flowchart showing the processing content of the manual regeneration control. The control unit 36 starts the process from step S1 when the power is turned on or when the engine is started and the process is started. In step S1, it is checked whether or not the manual regeneration flag set to 0 in the initial setting is 0. If it is 0, the process proceeds to step S2.

  In step S2, the state of the DPF is detected by the DPF pressure sensor 37, and if the level is the manual regeneration enabled level or the level required for manual regeneration, the process proceeds to step S3. In step S3, the DPF indicator lamp 28c is turned on and off and the buzzer 41 is sounded to notify the operator that regeneration control is necessary, and the process proceeds to step S4.

  In step S4, it is determined whether a manual regeneration condition, which is a predetermined condition for determining whether the regeneration control may be executed during the execution of the manual regeneration control, is satisfied. On the other hand, if not established, the process returns to step S1.

  Incidentally, in the present embodiment, in order to satisfy the manual regeneration condition, it is necessary to confirm that the automatic rotation speed control is OFF by the engine rotation dial 33, and to operate the engine at a low speed by the engine rotation dial 33 (specifically, That the traveling speed of the traveling machine body 2 is stopped by the main transmission lever potentiometer, and that the cutting / depowering power clutch switch 34 controls the operation of the preprocessing unit 3 and the threshing device 4. It is necessary that all of the above four conditions, that is, drive stop is confirmed, are satisfied.

  In step S5, the on / off state of the DPF manual regeneration switch 31 is checked. If the on / off operation has been performed, the process proceeds to step S6 in order to start execution of the regeneration control. The process returns to S1. In step S6, the manual regeneration flag is set to 1, and the process returns to step S1.

  If the manual regeneration flag is other than 0 in step S1, the process proceeds to step S7. In step S7, it is confirmed whether or not the manual regeneration flag is 1, and if it is 1, the process proceeds to step S8. In step S8, the state of the DPF is confirmed by the DPF pressure sensor 37, and if the state of the DPF is other than the unnecessary regeneration level, the process proceeds to step S9. In step S9, reproduction control is performed, and the process proceeds to step S10. In step S10, the DPF indicator lamp 28c is turned on to notify the operator that a series of processes from the regeneration control is being executed, and the process returns to step S1.

  If the state of the DPF has reached the regeneration unnecessary level in step S9, there is no point in continuing the execution of the regeneration control, and the process proceeds to step S11. That is, during the execution of the manual regeneration control, after the execution of the regeneration control is started once and until the state of the DPF becomes the regeneration unnecessary level, step S1 → step S7 → step S8 → step S9 → step S10 → step The process is repeated from S1 to..., And while the execution of the regeneration control is continued, when the state of the DPF becomes the regeneration unnecessary level, the process proceeds from step S8 to step S11, and the execution of the regeneration control ends. In step S11, the manual regeneration flag is set to 2, and the process returns to step S1.

  If the manual regeneration flag is 2 in step S7, the process proceeds to step S12. In step S12, it is checked whether or not a cool-down time, which is a predetermined time, has elapsed since the start of the cool-down control described below. If the cool-down control has not been executed yet, If the cool down time has not elapsed since the start of execution, the process proceeds to step S13.

  In step S13, after executing the regeneration control, cool down control for cooling down the engine and the like is executed, and the process proceeds to step S14. In step S14, the DPF indicator lamp 28c is turned on to notify the operator that a series of processes from the regeneration control is being executed, and the process returns to step S1.

  If the execution of the cool-down control is started in step S12 and it is confirmed that the cool-down time has elapsed since the start, the process proceeds to step S15. That is, during the period from the start of the execution of the cool-down control to the elapse of the cool-down time, the processing is repeated in the order of step S 1 → step S 7 → step S 12 → step S 13 → step S 14 → step S 1 →. The execution of the down control is continued, and when the cool down time has elapsed, the process proceeds from step S12 to step S15, and the execution of the cool down control ends. In step S15, the manual regeneration flag is reset to 0, and the process returns to step S1.

  FIG. 8 is a flowchart showing the processing content of the well-known notification control. The control unit 36 starts the process from step S21 when the power is turned on or the engine is started and the process is started. In step S21, the direction indicating operation is detected by the turn signal switch 40, and if the direction indicating leftward operation is detected, the process proceeds to step S22. In step S22, the left three turn signals 13L, 14L, and 16L are all turned on and off to indicate that the traveling body 2 is turning to the left or is turning, and the process returns to step S21.

  When a right direction instruction operation is detected in step S21, the process proceeds to step S23. In step S23, all the three right turn signals 13R, 14R, 16R are blinked to indicate that the traveling body 2 is turning to the right or is turning, and the process returns to step S21.

  In step S21, if it is confirmed that the direction indicating operation to either the left or right is not detected by the turn signal switch 40 and the vehicle is in the neutral state, the process proceeds to step S24. In step S24, the on / off state of the notification execution switch 32 is confirmed, and if it is in the on-operation state, it is made known to persons around (the main combine) of the traveling machine body 2 using the above-mentioned various surrounding notification means. While the process proceeds to step S25 for the purpose, in the case of the cutting operation state, such publicity is unnecessary, and the process returns to step S21.

  In step S25, the presence or absence of driving of the pre-processing unit 3 and the threshing device 4 is confirmed by the mowing / threshing power clutch switch 34. If the pre-processing unit 3 and the threshing device 4 are in a stopped state, step S26 is performed. Proceed to. In step S26, the state of the manual regeneration flag is checked, and if the manual regeneration flag is set to 1 or 2, notification of the regeneration control or the cool-down control to be executed thereafter is given to the surrounding persons. If the manual regeneration flag is reset to 0, the regeneration control and the subsequent cool-down control are not executed and no notification is required. Return to processing.

  In step S27, a subroutine of DPF manual regeneration notification control is executed, and the process returns to step S21.

  In step S25, when it is confirmed that the pre-processing unit 3 and the threshing device 4 are driven and the harvesting operation is being performed, the process proceeds to step S28. In step S28, a subroutine for fir-full notification control is executed, and the process returns to step S21.

  That is, in the surroundings notification control configured by the processing of steps S21 to S28, the processing of the direction instruction by the direction instruction operation is preferentially executed, and when the direction instruction is not performed, the DPF manual regeneration notification control or Fir-full notification control is executed. Incidentally, the fir-full notification control is executed prior to the DPF manual regeneration notification control.

  FIG. 9 is a flowchart showing the processing contents of the subroutine of the DPF manual regeneration notification control. The processing of this subroutine starts from step S31. In step S31, the state of the manual regeneration flag is checked. If the manual regeneration flag is 1, the process proceeds to step S32, and if the manual regeneration flag is 2, the process proceeds to step S33.

  In step S32, since the reproduction control is being executed, a reproduction notification process for notifying the surrounding person of the reproduction control is executed, and the process returns to the main routine shown in FIG. In the reproduction notification process, the notification to the surrounding persons is performed by using a reproduction notification pattern that is a notification pattern for rapidly blinking the six lamps 13L, 13R, 14L, 14R, 16L, and 16R.

  In step S32, since the cool-down control started after the reproduction control is being executed, an extension notification process for notifying the surrounding person of the execution is executed, and the process returns to the main routine shown in FIG. In the extension notification process, the same six lamps 13L, 13R, 14L, 14R, 16L, and 16R are used, and notification to the surrounding persons is performed using an extension notification pattern that is different from the reproduction notification pattern. Specifically, in the extension notification process, the notification is performed using the extension notification pattern in which the six lamps 13L, 13R, 14L, 14R, 16L, and 16R blink at a lower speed than the reproduction notification pattern.

  The reproduction notification pattern and the extension notification pattern may be the same, and the lamps 13L, 13R, 14L, 14R, 16L, and 16R may blink at the same intervals.

  FIG. 10 is a flowchart showing the contents of a subroutine for fir-full notification control. The processing of this subroutine starts from step S41. In step S41, the fir storage amount sensor 39 confirms whether or not the grain (mainly paddy) is stored in the Glen tank 6 in an amount equal to or more than a predetermined amount that is full or close to the full amount. If the kernels are stored in the main routine, the process proceeds to step S42; otherwise, the process returns to the main routine shown in FIG.

  In step S42, a storage notification process is performed to notify the well-known person that grains (mainly paddy) are stored in the Glen tank 6 in an amount equal to or greater than the notification amount, and the main routine shown in FIG. Reverse processing. In the storage notification process, the same six lamps 13L, 13R, 14L, 14R, 16L, 16R as those used in the reproduction notification process and the extension notification process are used, and they are all turned on and off.

  Incidentally, the storage notification process is executed prior to the control notification process and the extension notification process depending on the processing content of the surrounding notification control. In other words, the storage notification process is performed in a state where the control notification process and the extension notification process are not performed. More specifically, the control notification process, the extension notification process, and the storage notification process are executed exclusively, and the storage notification process is executed prior to the control notification process or the extension notification process.

  According to the present combiner configured as described above, it is possible to appropriately perform various notifications to the well-known person using the six lamps 13L, 13R, 14L, 14R, 16L, and 16R. In particular, when the traveling body 2 has stopped traveling due to the manual regeneration condition in step S4, the manual regeneration control is executed, and at this time, the regeneration notification process is executed. Quickly understand the situation.

  Note that the buzzer 41 may be used as the well-known notifying means. The interval of the intermittent sounding of the buzzer 41 is made to correspond to the interval of blinking of the lamps 13L, 13R, 14L, 14R, 16L, 16R, and the continuous buzzer 41 is output. By making the blowing sound correspond to the lighting of the lamps 13L, 13R, 14L, 14R, 16L, 16R, it is possible to perform notification based on the same concept.

  Also, the presence or absence of driving of the pre-processing unit 3 is determined not by the power clutch switch 34 but by a rotation sensor for detecting the rotation of the transmission shaft of the pre-processing unit 3 or a detection switch for detecting the intermittent operation or intermittent operation of the reaping clutch. In this case, the rotation sensor and the detection switch function as the mowing drive detecting means. Whether or not the threshing device 4 is driven is detected not by the power clutch switch 34 but by a rotation sensor that detects rotation of the transmission shaft of the threshing device 4 or a detection switch that detects intermittent operation or intermittent operation of the work clutch. Is also good. In this case, the rotation sensor and the detection switch function as the threshing drive detection unit.

  Also, the presence or absence and traveling speed of the traveling machine body 3 are provided not on the main transmission lever potentiometer 38 but on the transmission shaft of a traveling transmission that transmits power by shifting the power from the engine to the left and right crawler traveling devices 1L and 1R. It may be detected by a rotation sensor or the like. In this case, the rotation sensor functions as the traveling detection means.

  Further, the manual regeneration conditions are not limited to the above four conditions, and may be appropriately determined in consideration of an environment in which the regeneration control may be performed during the manual regeneration control.
