When the operation of the first work lever 43 to the neutral position is detected on the basis of the output of the first lever sensor 67, the lift valve 71 is stopped to stop the oil supply to the lift cylinder 2 And stops the operation of the elevating cylinder 2 by switching to the steerable / non-steerable stop state to perform the elevation stop control for stopping the seedling machine 4 at the height position at that time.

That is, by the control operation of the elevation control means 66A based on the output of the first lever sensor 67, the submersible device 4 can be moved up and down to an arbitrary height position.

When the operation of the first work lever 43 to the automatic position is detected on the basis of the output of the first lever sensor 67, the elevation control means 66A outputs the output of the second lever sensor 68 The operation of the lift valve 71 is controlled.

For example, when the downward operation of the second work lever 44 is detected based on the output of the second lever sensor 68, the center float 28 is grounded and the output of the float sensor 69 Up valve 71 is discharged during a period of time until the state of the preset center float 28 corresponding to the control target angle (the output of the float sensor 69 falls within the dead band width of the control target angle) The ascending and descending valve 71 is shifted to the stopping position in accordance with the output of the float sensor 69 coinciding with the control target angle. And stops the extension operation of the lifting cylinder 2 to automatically stop the submersible device 4 at a predetermined ground height position (work height position) corresponding to the control target angle. Thereafter, the operation of the lifting cylinder 71 is controlled so that the output of the float sensor 69 coincides with the control target angle to switch the operating state of the lifting cylinder 2, Up and down control for automatically elevating and lowering the submersible device 4 in a state in which the submersible device 4 maintains the predetermined ground height position regardless of the pitch of the running vehicle body 1.

Specifically, based on the output of the first lever sensor 67, after the operation of the first work lever 43 from the neutral position to the lowered position is detected, the center float The blower relay 77 is energized to switch the blower relay 77 from the battery 76 to the closed state allowing the energization of the blower 35 to start the blower 35 And performs blower start control. Thereafter, when the operation of the first work lever 43 to the food position is detected based on the output of the first lever sensor 67, the food portion clutch 23 and the friction portion 74 are turned off On control for controlling the operation of the aseptic clutch motor (73) and the specific clutch motor (75) so as to be switched to the state shown in Fig. As a result, the seed drill 4 and the fertilizer 6 are switched from the stopped state to the operating state.

It is also possible to detect the operation of the first work lever 43 from the food portion position to the lowered position based on the output of the first lever sensor 67 in the operating state of the seeder 4 and the fertilizer 6 The blower relay 77 is stopped to stop the blower 35 by switching the blower relay 77 from the battery 76 to the open state in which energization of the blower 35 is stopped, Control is performed.

As shown in Figs. 2, 12 and 13, a meter panel 81 is disposed at a position in front of and below the steering wheel 39 in the boarding operation section 38. Fig. The meter panel 81 is provided with a liquid crystal display 82, a display electronic control unit (hereinafter abbreviated as display ECU) 83, and the like. The liquid crystal display 82 is provided with a fuel remaining amount display portion 82A for graphically displaying the remaining amount of fuel, a water temperature display portion 82B for graphically displaying the temperature of the engine cooling water, and a total of the engine 7 serving as an index of maintenance, An auxiliary display section (an example of the notification means and display means) 82C for displaying the operation time and the like, and the like.

While the operation of the engine 7 is being detected based on the output of the engine sensor 86 composed of the rotation sensor of the electromagnetic pickup type that detects the output revolution number of the engine 7, (Not shown) provided in the display ECU 83 performs the operation time measurement process for measuring the operation time of the engine 7 and performs the operation time measurement process performed every time the engine 7 is operated, 7) to calculate the total operation time of the engine 7 (an example of the integration operation time).

14, the ECU 66 and the display ECU 83 are connected to the main switch 87 of the key operation type provided in the boarding operation section 38, (76). When the power supply from the battery 76 is cut off by the operation from the ON position to the OFF position of the main switch 87, the energized state is maintained by the self-holding circuit (not shown) provided therein, After storing various information such as the total operation time of the engine 7 at the stage where the energization from the battery 76 is disconnected, the energization by the self-holding circuit is stopped and the operation is stopped. The main switch 87 is connected to an engine starting starter 89 via a brake switch 88 formed of a limit switch.

Although not shown, the brake switch 88 is switched from the open state to the closed state as the brake pedal 42 reaches the stepping limit position, and is released from the stepping limit position of the brake pedal 42 So as to be switched from the closed state to the open state.

That is, only when the operation from the ON position to the START position of the main switch 87 is performed in the braking state of the brake 25 in which the brake pedal 42 is stepped to the stepping limit position, The battery 76 is allowed to energize the starter 89 so that the engine 7 can be started by the operation of the starter 89 based on the operation of the main switch 87. [

As shown in Figs. 5, 6, 8, 12 and 14, the ECU 66 is provided with a guide plate 55 for detecting the operation of the peripheral speed lever 40 to the engine stop position 55d A starter relay 91 provided in parallel with the main switch 87 between the battery 76 and the brake switch 88 based on the output of the provided stop sensor 90 or the like, And an engine control means 66D for controlling the operation of the igniter relay 93 for interrupting energization of the igniter 92 of the engine 7 to switch the engine 7 between the active state and the stopped state . Further, a limit switch is employed for the stop sensor 90.

The engine control means 66D detects the interruption of the grafting operation based on the output of the stop sensor 90 by the operation of the peripheral speed lever 40 in the engine stop position 55d during the operation of the engine 7 And performs the engine start control when the restart of the grafting operation is detected by the departure of the peripheral speed lever 40 after the engine stop by the engine stop control from the engine stop position 55d .

15, in the engine stop control, the engine control means 66D detects the stop of the grafting operation by the operation of the peripheral speed lever 40 to the engine stop position 55d, The information about the ascending and descent of the submergible machine 4 held by the control means 66A, the information about the interruption of the work power held by the work operation control means 66B, ), And stores them in the EEPROM (step # 1).

Next, it is determined whether or not a condition for stopping the engine is established (steps # 2 to 4).

Specifically, based on the output of the engine sensor 86, it is determined whether or not the number of output rotations of the engine 7 is equal to or less than the set number of rotations (for example, the number of idling rotations) It is determined whether or not the voltage of the battery 76 is equal to or higher than the set value based on the output of the voltage detector 94 (see FIG. 12) for detecting the voltage of the water temperature sensor 85 It is determined based on whether or not the temperature of the engine coolant is equal to or higher than a set value (for example, 55 ° C) (Step # 4). It is determined that the condition for stopping the engine is satisfied only when the number of output rotations of the engine 7 is equal to or lower than the set rotation speed and the voltage of the battery 76 is equal to or higher than the set value and the temperature of the engine cooling water is equal to or higher than the set value, In the other cases, it is determined that the condition for stopping the engine is not established.

On the basis of the various types of information read in step # 1, when the conditions for the engine stop are satisfied, the state immediately before the start of the engine stop control is determined to be the operating state in which the seed drill 4 and the fertilizer 6 are operated [Step # 5].

In the case of the work state, the blower stop control and the execution of the clutch off control are instructed to the work operation control means 66B to stop the blower 35 and simultaneously turn off the food portion clutch 23 and the friction portion 74 (Steps # 6 and # 7). Further, the stop control of the work control operation such as automatic elevation control or horizontal control executed immediately before the engine stop control is started is commanded to the elevation control means 66A, the rolling control means 66C, and the like to stop the work control operation [Step # 8]. Thereafter, the igniter relay 93 is energized to switch the igniter relay 93 from the battery 76 to the open state in which energization to the igniter 92 is stopped, thereby stopping the engine 7 and ending the engine stop control [Step # 9].

On the other hand, if the engine is not in the work state, the process directly shifts to step # 9 to stop the engine 7 and end the engine stop control.

If the conditions for stopping the engine are not established in steps # 2 to # 4, based on the output of the stop sensor 90, it is determined whether or not the peripheral speed lever 40 is the engine stop position 55d, Step # 10] and the engine stop position 55d, the process returns to Step # 2 to determine whether or not the engine stop condition is satisfied. If it is not the engine stop position 55d, it is determined that the releasing operation from the engine stop position 55d of the peripheral speed lever 40 has been performed, and the engine stop control is terminated.

That is, in the case of stopping the grafting operation for, for example, clogging of the tray 26, dispensing of fertilizer to the hopper 34, or elimination of clogging of the fertilizer, the operation of the peripheral speed lever 40, By moving the peripheral speed lever 40 to the neutral path 55a by a stepping operation of the engine 7 to the stepping limit position of the engine speed sensor 42 and then operating the peripheral speed lever 40 to the engine stop position 55d, Unnecessary fuel consumption due to the operation of the engine 7 can be prevented even during the auxiliary operation such as drainage, fertilizer supply or clogging of the fertilizer, .

When the engine 7 is automatically stopped by the engine stop control in the working state, the blower 35 is stopped during the stop of the engine 7 because the submersible device 4 and the fertilizer device 6 are also automatically stopped. It is possible to prevent the occurrence of problems such as battery exhaustion caused by operation of the battery.

In addition, even if the peripheral speed lever 40 is operated at the engine stop position 55d, the engine 7 is not automatically stopped when the engine stop condition is not satisfied, so that the voltage of the battery 76 It is possible to prevent a problem such as that it takes time to restart the engine 7 due to automatic stop of the engine 7 when the temperature of the engine 7 is lower than the set value or when the temperature of the engine coolant is lower than the set value.

16, in the engine start control, the engine control means 66D detects the restart of the grafting operation by departing from the engine stop position 55d of the peripheral speed lever 40, (Step # 1). [Step # 1] The CPU judges whether or not the state immediately before the engine stop control is started based on the read various information (Step # 2).

Then, in the case of the work state, first, the blower 35 is operated by instructing the work operation control means 66B to execute the above-described blower start control, and then the work operation control means 66B (Step # 4) to instruct the execution of the above-described clutch-on control to turn the food-portion clutch 23 and the friction clutch 74 on. In addition, for example, the restarting of the control operations for the work such as the automatic elevation control and the horizontal control executed just before the start of the engine stop control is commanded to the elevation control means 66A, the rolling control means 66C, [Step # 5].

Next, the energization to the igniter relay 93 is stopped and the igniter relay 93 is switched from the battery 76 to the energized state to allow the engine 7 to start, thereby allowing the start of the engine 7 The main switch 87 is switched to the closed state in which the starter relay 91 is energized and the starter relay 91 is energized from the battery 76 to the starter 89 during the set time for starting the engine, The starter 89 is actuated by the energization of the starter 89 from the battery 76 bypassing the starter 89 to start the engine 7 (steps # 7 to # 9). Then, it is determined whether or not the number of output rotations of the engine 7 is equal to or greater than the set rotational speed based on the output of the engine sensor 86 (step # 10) The engine start control is terminated. It is determined that the engine 7 has not been started, and the process returns to the step # 7, where the starter 89 is again operated to start the engine 7. [

On the other hand, if it is not in the working state in step # 2, the process directly shifts to step # 6 to perform the control operations in steps # 6 to # 10 to start the engine 7 and then finish the engine startup control.

That is, when a restart operation is performed to move the peripheral speed lever 40 from the engine stop position 55d to the neutral path 55a to restart the engine 7 after the engine stop by the engine stop control, The operation state of the seed plant 4 and the fertilizer 6 can be automatically reproduced in the same state as the operation state before the engine stop in accordance with the restart operation when the state before the engine stop is in the work state, Thus, by operating the peripheral speed lever 40 from the neutral path 55a to the forward speed change path 55b after the engine 7 is restarted, the planting work can be restarted in the same operating state as before the engine stop.

As described above, since the starter relay 91 is provided in parallel with the main switch 87 between the battery 76 and the brake switch 88, the brake pedal 42 is moved to the stepping limit position Only the starter relay 89 is moved from the battery 76 via the starter relay 91 to the starter 89 only when the operation of releasing the peripheral speed lever 40 from the engine stop position 55d is performed in the braking state of the stepped brake 25. [ It is possible to start the engine 7 by the operation of the starter 89 based on the operation of the peripheral speed lever 40. [

Even when the starting operation of the engine 7 due to the energization of the starter 89 can not be performed from the battery 76 via the starter relay 91 due to the failure of the starter relay 91 or the like, The starting operation of the engine 7 is enabled by the energization of the starter 89 from the battery 76 based on the operation of the switch 87. Therefore, the engine 7 is started by the operation of the main switch 87 .

The engine control means 66D always monitors the output of the water temperature sensor 85 after the engine stop by the engine stop control and detects the temperature of the engine cooling water based on the output of the water temperature sensor 85 to the set upper limit temperature For example, 110 DEG C), even if the peripheral speed lever 40 is located at the engine stop position 55d, the engine start control described above is performed and the engine 7 is forcibly restarted, And a cooling fan (not shown) operated by power from the engine 7 is operated to cool the engine 7 and engine cooling water.

12, the display ECU 83 is provided with a stop time accumulating means 83C for accumulating the stop time of the engine 7 by the engine stop control, and a total operation time calculating means (Accumulation time summing means) 83D as a control program. A reset switch 95 composed of a momentary switch for outputting a reset command to the operation time integrating means 83B and the like of the display ECU 83 every time the pressing operation is performed is provided in the vicinity of the meter panel 81, And a display changeover switch 96 composed of a momentary switch for outputting a display changeover command to the display control means 83A of the display ECU 83 every time an operation is performed.

The running time accumulating means 83B accumulates the running time of the engine 7 obtained in the running time measuring process after receiving the reset command from the reset switch 95 in parallel with the above total running time accumulating process And the post-reset operation time integrating process for obtaining the engine operation time (an example of the cumulative operation time) after the reset is performed.

While the stopping time accumulating means 83C detects the stopping of the engine 7 by the engine stop control based on the outputs of the engine sensor 86 and the stop sensor 90, Stop time measurement process for measuring the stop time of the engine 7 and integrates the stop time of the engine 7 obtained in the stop time measurement process performed every time the engine 7 stops by the engine stop control, A total stop time integration process for obtaining the total stop time (an example of the integration stop time) of the engine 7 is performed. In addition to the total stop time accumulation processing, the stop time of the engine 7 obtained in the stop time measurement processing after receiving the reset command from the reset switch 95 is integrated to obtain the engine stop time And a post-reset stop time accumulating process for obtaining a post-reset stop time.

The total operation time calculating means 83D calculates the total operation time of the engine 7 obtained by the operation time integrating means 83B as the main operation time required for the main operation such as the planting work performed in a state in which the engine 7 is operated And the total stopping time of the engine 7 by the engine stop control calculated by the stop time accumulating means 83C is set to be the assistant necessary for the auxiliary operation such as the stopping of the main operation and the removal of the clogging of fertilizer, (An example of the total accumulated time) in consideration of the auxiliary work time required for the auxiliary work performed during the engine stop by the engine stop control, which can not be obtained by employing the engine stop control, The total operation time calculation processing is performed. In parallel with the total operation time accumulation process, the sum of the engine operation time after reset calculated by the operation time integration means 83B and the engine stop time after reset, which is obtained by the stop time integration means 83C, An example of the integration time) is obtained.

The display control means 83A is based on the outputs of the engine sensor 86 and the stop sensor 90 as the display ECU 83 starts operating from the OFF position to the ON position of the main switch 87 To switch the display state of the auxiliary display section 82C based on the display switching command from the display changeover switch 96. The manual display switching control section 96 is configured to switch the display state of the auxiliary display section 82C automatically, And performs display switching control.

As shown in Fig. 17, in the automatic display switching control, the display control means 83A firstly displays the automatic display switching control for a predetermined period of time (for example, 2 seconds) , The display state of the auxiliary display section 82C is maintained in the total operation time display state indicating the total operation time of the engine 7 obtained by the operation time integration means 83B (Steps # 1 and # 2). Thereafter, when the set time has elapsed, it is determined whether or not a condition for stopping the engine is established (step # 3). The condition for stopping the engine here is the same as the condition for stopping the engine in the engine stop control, and therefore, it is simply described as a condition for stopping the engine.

When the condition for stopping the engine is established, the display state of the auxiliary display section 82C is switched from the total operation time display state to the ECO display state in which the characters "ECO" It notifies the driver that execution of the engine stop control based on the operation to the engine stop position 55d is possible (Step # 4). When the condition for stopping the engine is not established, the display state of the auxiliary display section 82C is maintained in the total operation time display state until the engine stop condition is satisfied, and the engine stop position 55d To the driver that the engine stop control based on the operation of the engine stop control can not be executed.

After switching to the ECO display state, it is determined based on the output of the stop sensor 90 whether or not the operation position of the peripheral speed lever 40 is the engine stop position 55d (step # 5) The display state of the auxiliary display section 82C is set to the set stop time of the engine 7 obtained by the character of "ECO" in the ECO display state and the stop time accumulating section 83C by the set time (Step # 6), the engine stop control is switched to the ECO stop time display mode for switching display every time the engine is stopped . If the condition for stopping the engine is satisfied, it is determined whether or not the condition for stopping the engine is established again (step # 7). If the condition for stopping the engine is established, the display state of the auxiliary display section 82C Is returned to the step # 5 while maintaining the ECO display state, and the control operation after the step # 5 is performed. When the condition for stopping the engine is not established, the display state of the auxiliary display section 82C is switched from the ECO display state to the total operation time display state, and based on the operation of the peripheral speed lever 40 to the engine stop position 55d The engine stop control can not be executed. [Step # 8] After that, the process returns to Step # 3 to perform the control operation of Step # 3 and thereafter.

After switching to the ECO stop time display state, it is determined whether or not the engine 7 is started based on the output of the engine sensor 86 (step # 9). If the engine 7 is started, It is determined whether or not the stop condition is satisfied (step # 10). If the engine stop condition is satisfied, the process proceeds to step # 4 to display the display state of the auxiliary display section 82C in the ECO stop time display state ECO display state to notify the driver that the engine 7 is in the operating state and that execution of the engine stop control based on the operation of the peripheral speed lever 40 to the engine stop position 55d is possible, The control operation after step # 5 is performed. If the condition for stopping the engine is not established, the process proceeds to step # 8 to change the display state of the auxiliary display section 82C from the ECO stop time display state to the total operation time display state. After the driver is notified that execution of the engine stop control based on the operation of the peripheral speed lever 40 to the engine stop position 55d is not possible, the control operation from step # 3 onward is performed.

When the engine 7 is not started in step # 9, the display state of the auxiliary display section 82C is maintained in the ECO stop time display state.

While the automatic display switching control is being executed, the outputs of the main switch 87 and the display changeover switch 96 are always monitored, and the main switch 87 is turned on based on the output of the main switch 87, When the operation to the OFF position is detected, the automatic display switching control is terminated, and when the pressing operation of the display changeover switch 96 is detected based on the output of the display changeover switch 96, Control.

When the depressing operation of the display changeover switch 96 is detected in the stop time display state, the display state of the auxiliary display section 82C is switched to the state of "RECO" indicating that the display content in the auxiliary display section 82C is the engine stop time after reset The engine stop time after reset is switched to the post-reset stop time display state in which the character and stop time accumulating means 83C switchably display the engine stop time after reset for each set time (for example, 2 seconds), and notifies the driver of the engine stop time after reset .

When the pressing operation of the display changeover switch 96 is detected in the post-reset stop time display state, the display state of the auxiliary display section 82C is switched to the state of "W" indicating that the display content in the auxiliary display section 82C is the total operation time The total operation time obtained by the character and total operation time calculation means 83D is switched to the total operation time display state for switching display every set time (for example, 2 seconds), and the total operation time Notify the driver.

When the pressing operation of the display changeover switch 96 is detected in the total operation time display state, the display state of the auxiliary display section 82C is set to "RW" indicating that the display contents in the auxiliary display section 82C is the total operation time after resetting. And the total operation time after reset, which is obtained by the total operation time calculation means 83D, is switched to a reset operation time display state in which the display is switched for each set time (for example, 2 seconds) And the total operation time after resetting to the driver.

When the pressing operation of the display changeover switch 96 is detected in the total operation time display state after the resetting, the display state of the auxiliary display section 82C is set to the set state of the character "AUTO" indicating the return to the automatic display changeover control, And then switches to the display state in accordance with the control operation of the automatic display switching control, thereby notifying the driver that the display on the auxiliary display portion 82C is based on the automatic display switching control.
