Specifically, when the operation to the raised position of the first work lever 43 is detected based on the output of the first lever sensor 67, the lifting valve 71 is supplied with oil to the lifting cylinder 2. By switching to the supply state, the lift cylinder 2 is contracted and lift control for raising the planting device 4 is performed. When the operation to the lowered position of the first work lever 43 is detected based on the output of the first lever sensor 67, the lift valve 71 is discharged to discharge oil from the lift cylinder 2. By switching, the lowering control which extends the lifting cylinder 2, and lowers the planting apparatus 4 is performed. When the operation to the neutral position of the first work lever 43 is detected on the basis of the output of the first lever sensor 67, the supply / lowering valve 71 stops supply / discharge of oil to the lifting cylinder 2. The lifting stop control is performed to stop the operation of the lifting cylinder 2 by switching to the sudden discharge stop state, and to stop the seedling plant 4 at the height position at that time.

For example, when the operation to the lower side of the second work lever 44 is detected on the basis of the output of the second lever sensor 68, the center float 28 is grounded to output the float sensor 69. The lifting and lowering valve 71 is discharged until a state that matches the control target angle of the preset center float 28 (the output of the float sensor 69 falls within the deadband width of the control target angle) is obtained. The seedling device 4 is lowered by switching to the state and extending the lifting cylinder 2, and as a result, the output of the float sensor 69 coincides with the control target angle, thereby rapidly stopping the lifting valve 71. By switching to the state and stopping the extension operation of the elevating cylinder 2, an automatic lowering control is performed to automatically stop the seedling device 4 at a predetermined ground height position (work height position) corresponding to the control target angle. Thereafter, by controlling the operation of the lifting valve 71 so as to maintain the state in which the output of the float sensor 69 coincides with the control target angle, the operating state of the lifting cylinder 2 is switched, thereby resulting from the ups and downs of the wrapping surface. Regardless of the pitching of the traveling vehicle body 1, the automatic raising / lowering control which automatically raises and lowers the planting device 4 in the state which the planting device 4 maintains a predetermined | prescribed ground height position is performed. And when the operation to the upper direction of the 2nd work lever 44 is detected based on the output of the 2nd lever sensor 68, the output of the link sensor 70 controls the link mechanism 3 preset. Until the state corresponding to the upper limit angle (the output of the link sensor 70 falls within the deadband width of the control upper limit angle) is obtained, the elevating valve 71 is switched to the supply state to raise the elevating cylinder 2. The raising and lowering of the raising and lowering cylinder 2 is carried out by raising and lowering the planting device 4 by the contraction operation, and as the output of the link sensor 70 coincides with the control upper limit angle by the raising, By stopping the contraction operation, automatic raising control is performed to automatically stop the planting apparatus 4 at a predetermined upper limit position corresponding to the control upper limit angle.

Blow start control is performed. Then, when the operation to the planting position of the first work lever 43 is detected based on the output of the first lever sensor 67, the planting clutch 23 and the fertilizing clutch 74 are turned on in the off state. The clutch on control which controls the operation of the planting clutch motor 73 and the fertilizing clutch motor 75 is performed so that it may switch to a state. Thereby, the planting apparatus 4 and the fertilizing apparatus 6 are switched to a working state from a stationary state.

In addition, in the operating state of the said seedling apparatus 4 and the fertilizing apparatus 6, operation | movement from the planting position of the 1st work lever 43 to a falling position is detected based on the output of the 1st lever sensor 67. Moreover, as shown in FIG. In one case, blower stop which stops blower 35 by stopping energization to blower relay 77 and switching blower relay 77 to the open state which interrupts electricity supply to blower 35 from battery 76 is stopped. Control is performed. Further, clutch off control is performed to control the operation of the planting clutch motor 73 and the fertilizing clutch motor 75 so that the planting clutch 23 and the fertilizing clutch 74 are switched from the on state to the off state.

Thereby, the planting apparatus 4 and the fertilizing apparatus 6 are switched from an operating state to a stationary state.

The rolling control means 66C is based on the output of the rolling sensor 78 mounted on the planting device 4 so as to detect the rolling angle of the planting device 4 with the support shaft 5 in the front-rear direction as a supporting point. In the front-rear direction such that the output of the rolling sensor 78 coincides with the control target angle of the pre-set planting device 4 (the output of the rolling sensor 78 falls within the deadband width of the control target angle) is maintained. The operation of the electric rolling motor 79 provided in the rolling mechanism (not shown) which changes the rolling angle of the planting apparatus 4 with respect to the traveling vehicle body 1 which made the support shaft 5 the support point is controlled.

The control target angle of the planting apparatus 4 can be set and changed to arbitrary angles by operating the rolling angle setter 80 with which the boarding drive part 38 was equipped.

And when the operation position of the rolling angle setter 80 is a reference position, the rolling control means 66C will match the output of the rolling sensor 78 with the output at the reference position of the rolling angle setter 80. By controlling the operation of the rolling motor 79 so as to perform the horizontal control to hold the planting apparatus 4 in a horizontal position irrespective of the rolling of the traveling vehicle body 1 due to ups and downs and the like.

In addition, when the operation position of the rolling angle setter 80 is changed and changed to an arbitrary operation position according to the inclination of the halfway from the reference position, the output of the rolling sensor 78 sets the rolling angle after a setting change. By controlling the operation of the rolling motor 79 to coincide with the output of the machine 80, rolling of the planting device 4 arbitrarily set other than the horizontal posture irrespective of the rolling of the traveling vehicle body 1 due to the undulation of light and the like. It is comprised so that the inclination control of holding in a posture may be performed.

In addition, the rolling sensor 78 is equipped with an inclination angle sensor and an angular velocity sensor in order to detect the rolling angle of the planting device 4 with high accuracy and responsiveness. The rolling potentiometer 80 employs a rotary potentiometer.

Although illustration is abbreviate | omitted, the seedling apparatus 4 has three auxiliary clutches for planting which clamps down the transmission with respect to the planting mechanism 27 in two sets, and the transmission to the longitudinal feed mechanism 29 in one set of two sets.

Specifically, the auxiliary clutch control means assists so that when the signals from all three assistant selection switches are not output, the entire coarse work state in which all the auxiliary clutches for planting, longitudinal conveyance and time cost are turned on is obtained. Control the operation of the clutch motor. When the signal from the tide selector switch for the left two sets is output, the right four sets for the two sets of the left side for the seedling, the longitudinal feed and the auxiliary cost are turned off, and the remaining two auxiliary clutches are turned on. The operation of the auxiliary clutch motor is controlled to obtain a working state. When the signal from the tide selector switch for the left two sets and the center two sets is output, the auxiliary clutches for the four sets of the left and for the longitudinal feeding and the seaweed are turned off, and the remaining auxiliary clutches are turned on. The operation of the auxiliary clutch motor is controlled so that the right two-piece working state is obtained. When the signal from the tide selector switch for the right two sets is outputted, the left four sets for the two sets of the right side for the seeding, longitudinal feeding and the auxiliary cost are turned off, and the remaining four sets for the other auxiliary clutches are turned on. The operation of the auxiliary clutch motor is controlled to obtain a working state. When the signal from the tide selector switch for the right two sets and the center two sets is output, the respective auxiliary clutches for the four sets of the right side for the planting, the longitudinal feed and the cost are turned off, and the remaining auxiliary clutches are in the on state. The operation of the auxiliary clutch motor is controlled so that the left two-piece working state is obtained.

From the above configuration, the ECU 66 can grasp the work assistant changed according to the work situation based on the output of each assistant selection switch. In addition to the work assistants, various kinds of information such as work time, vehicle speed, the amount of hair drawn by each planting mechanism 27, and the gear shift stage of the weekly transmission device 22 in each work assistant are acquired. You can find the working area and the amount of hair used.

As shown in FIG. 2, FIG. 12, and FIG. 13, the meter panel 81 is arrange | positioned in the position below the front of the steering wheel 39 in the boarding driver 38. As shown in FIG. The meter panel 81 includes a liquid crystal display 82, a display electronic control unit (hereinafter abbreviated as display ECU) 83, and the like. The liquid crystal display 82 includes a fuel remaining amount display portion 82A for graphically displaying a residual amount of fuel, a water temperature display portion 82B for graphically displaying a temperature of engine cooling water, and an engine 7 serving as an index of maintenance such as oil change. 82 C of auxiliary display parts (an example of a notification means and a display means) etc. which display a running time etc. are displayed. The display ECU 83 is configured using a microcomputer having a CPU, an EEPROM, or the like, and is connected to the ECU 66 so as to be able to communicate with each other by in-vehicle communication such as CAN communication. The display ECU 83 accumulates the operating time of the display control means (an example of the notification control means) 83A and the engine 7 for controlling the display operation of the fuel remaining amount display portion 82A, the water temperature display portion 82B, and the like. The operation time integration means 83B and the like are provided as a control program.

The display control means 83A changes the display of the fuel remaining amount display unit 82A based on the output of the fuel sensor 84 that detects the remaining amount of fuel stored in the fuel tank (not shown). The auxiliary display unit 82C based on the water temperature display change processing for changing the display on the water temperature display unit 82B based on the output of the water temperature sensor 85 that detects the temperature of the engine cooling water, the output of the operation time integration means 83B, and the like. Is configured to perform an auxiliary display change process or the like for changing the display.

While the operation time integration means 83B detects the operation of the engine 7 on the basis of the output of the engine sensor 86 composed of an electromagnetic pickup type rotation sensor that detects the output rotation speed of the engine 7, The engine obtained by the operation time measurement process performed by the timer (not shown) provided in the display ECU 83 to perform the operation time measurement process which measures the operation time of the engine 7, and is performed every time the engine 7 operates ( The total running time integration process of calculating the total running time (an example of integrated running time) of the engine 7 by integrating the running time of 7) is performed.

As shown in FIG. 14, the ECU 66 and the display ECU 83 are batteries obtained by the operation from the OFF position to the ON position of the key operated main switch 87 included in the boarding driver 38. It starts by energizing from 76. In addition, if the electricity 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 electricity supply state is maintained by a self-holding circuit (not shown) provided therein, After storing various information such as the total operating time of the engine 7 at the stage where power supply from the battery 76 is cut off in the EEPROM, the power supply by the self holding circuit is stopped and the operation is stopped. The main switch 87 is connected to the engine starter 89 via a brake switch 88 composed of a limit switch.

Although not shown, the brake switch 88 is switched from the open state to the closed state with the arrival of the brake pedal 42 to the stepping limit position, and is accompanied by the departure of the brake pedal 42 from the stepping limit position. It is configured to switch from the closed state to the open state.

That is, only when the operation from the ON position of the main switch 87 to the START position is performed in the braking state of the brake 25 in which the brake pedal 42 has been stepped to the stepping limit position, the brake pedal 42 passes through the main switch 87. It is configured to permit the energization of the starter 89 from the battery 76, and to start the engine 7 by the operation of the starter 89 based on the operation of the main switch 87.

5, 6, 8, 12, and 14, the ECU 66 includes a guide plate 55 to detect the operation of the main gear lever 40 to the engine stop position 55d. Based on the output of the provided stop sensor 90 and the like, the starter relay 91 provided in parallel with the main switch 87 between the battery 76 and the brake switch 88, and the engine 76 from the engine 76 An engine control means 66D is provided as a control program for controlling the operation of the igniter relay 93 for interrupting the energization of the igniter 92 of 7) to switch the engine 7 to an operating state and a stopped state. . In addition, a limit switch is used for the stop sensor 90.

When the engine control means 66D detects the interruption of the transplant operation by the operation of the main gear lever 40 to the engine stop position 55d during the operation of the engine 7 based on the output of the stop sensor 90. The engine start control is performed, and the engine start control is performed when resuming of the transplantation operation is detected by the deviation from the engine stop position 55d of the main gear lever 40 after the engine stop control by the engine stop control. .

As shown in FIG. 15, in the engine stop control, the engine control means 66D first moves up and down by detecting the interruption of the transplant operation by the operation of the main gear lever 40 to the engine stop position 55d. Information about the lifting and lowering of the planting device 4 held by the control means 66A, information about the interruption of the work power held by the work operation control means 66B, and the engine 7 obtained by the operation time integration means 83B. Various types of information such as the total operating time are read out and stored in the EEPROM (Step # 1).

Next, it is determined whether the engine stop condition is satisfied (steps # 2 to 4).

Specifically, based on the output of the engine sensor 86, it is determined whether the output rotational speed of the engine 7 is less than or equal to the set rotational speed (for example, idling rotational speed) (step # 2), and the battery 76 On the basis of the output of the voltage detector 94 (see FIG. 12) for detecting the voltage of the battery, it is determined whether or not the voltage of the battery 76 is equal to or higher than the set value (step # 3), and the output of the water temperature sensor 85 is determined. On the basis of this, it is determined whether or not the temperature of the engine cooling water is equal to or higher than the set value (for example, 55 ° C) (step # 4). And it is judged that the conditions for engine stop are satisfied only when the output rotation speed of the engine 7 is below a preset rotation speed, the voltage of the battery 76 is more than a setting value, and the temperature of engine cooling water is more than a setting value, In other cases, it is determined that the conditions for stopping the engine do not hold.

When the condition for stopping the engine is satisfied, it is determined whether the state immediately before the start of engine stop control is a working state in which the planting device 4 and the fertilizing device 6 are operated based on the various information read in step # 1. It is determined whether or not it is [Step # 5].

In the working state, the blow stop control and the clutch off control are executed to the operation operation control means 66B to stop the blower 35 and turn off the planting clutch 23 and the fertilizing clutch 74. Switch to the state (steps # 6, # 7). In addition, the operation control operation is stopped by instructing the lift control means 66A, the rolling control means 66C, or the like to stop the operation control operation such as, for example, the automatic lift control or the horizontal control, which was executed immediately before the engine stop control started. [Step # 8]. Thereafter, the igniter relay 93 is energized and the igniter relay 93 is switched to an open state in which the energization of the igniter 92 from the battery 76 is stopped, thereby stopping the engine 7 and ending the engine stop control. [Step # 9].

On the other hand, if it is not in the working state, the engine 7 is stopped by immediately moving to step # 9 to end the engine stop control.

If the engine stop condition is not satisfied in steps # 2 to # 4, it is determined whether or not the main gear lever 40 is at the engine stop position 55d based on the output of the stop sensor 90 [ Step # 10], in the case of the engine stop position 55d, the process returns to Step # 2 to determine whether the engine stop condition is satisfied. If it is not the engine stop position 55d, it is determined that the detachment operation from the engine stop position 55d of the main gear lever 40 has been performed, and the engine stop control ends.

That is, when the transplanting operation is interrupted, for example, for the seeding to the mother loading table 26, the fertilizer supply to the hopper 34, or the removal of the fertilizer clogging, the operation of the main gear lever 40 and the brake pedal are stopped. After the main gear lever 40 is moved to the neutral path 55a by the stepping operation to the stepping limit position of 42, the engine 7 is operated by operating the main gear lever 40 to the engine stop position 55d. It is possible to automatically stop the engine, thereby avoiding unnecessary fuel consumption due to the operation of the engine 7 even while performing auxiliary work such as collection of planting, fertilizer supply, or elimination of fertilizer clogging, thereby improving fuel economy. Can be planned.

In addition, when the engine 7 is automatically stopped by the engine stop control in the working state, the planting device 4 and the fertilizer 6 are also automatically stopped, so that the blower 35 is stopped while the engine 7 is stopped. The occurrence of a problem such as the battery running out due to the operation can be prevented.

Furthermore, even if the main gear lever 40 is operated at the engine stop position 55d, the engine 7 is not automatically stopped when the above-described engine stop condition is not satisfied. Therefore, the voltage of the battery 76 is increased. When the temperature is lower than the set value or when the temperature of the engine coolant is lower than the set value, it is possible to avoid the possibility that a problem such as a long time is required to restart the engine 7 due to the automatic stop of the engine 7.

As shown in FIG. 16, in engine start control, the engine control means 66D detects the resumption of the transplantation operation by deviating from the engine stop position 55d of the main gear lever 40, and thus stops the engine. Various kinds of information stored in the EEPROM immediately before the start of control are read out (step # 1), and whether or not the state immediately before the start of engine stop control is a working state is determined based on the various kinds of information read out (step # 2).

Then, in the working state, first, the blower 35 is operated by instructing the job operation control means 66B to execute the blower start control described above (step # 3), and then the job operation control means 66B. ), The planting clutch 23 and fertilizing clutch 74 are switched to the on state (step # 4). In addition, the control operation for the operation is executed by instructing the lift control means 66A or the rolling control means 66C to resume the control operation for work such as automatic lift control or horizontal control, which was executed immediately before the engine stop control started. Resume (step # 5).

Next, the engine 7 is started by stopping the energization of the igniter relay 93 and switching the igniter relay 93 from the battery 76 to the closed state which energizes the igniter 92 (step # 6). ], After that, during the set time for starting the engine, the main switch 87 is energized by switching the starter relay 91 to the closed state through which the starter relay 91 is energized from the battery 76 to the starter 89. The engine 7 is started by operating the starter 89 by energizing the starter 89 from the battery 76 bypassing the above (steps # 7 to # 9). Then, based on the output of the engine sensor 86, it is determined whether or not the output rotational speed of the engine 7 is equal to or greater than the set rotational speed [step # 10]. The engine start control is terminated when it is determined that it is. When it is not more than the set rotation speed, it is determined that the engine 7 is not started, and the flow returns to step # 7, and the starter 89 is operated again to start the engine 7.

On the other hand, when it was not in the work state in step # 2, it shifts to step # 6 immediately, and performs engine control control of step # 6-# 10, starts engine 7, and completes engine start control.

That is, after stopping the engine by the engine stop control, if the main gear lever 40 is moved from the engine stop position 55d to the neutral path 55a to restart the engine 7, restarting the engine 7 is performed. When the state before the engine stop is the working state, with the restart operation, the operating states of the planting apparatus 4 and the fertilizing apparatus 6 can be automatically reproduced in the same state as the operating state before the engine stop, Thereby, by operating the main gear lever 40 from the neutral path 55a to the forward shift path 55b after restarting the engine 7, it is possible to resume the seeding operation in the same operating state as before the engine stop.

As described above, since the starter relay 91 is mounted in parallel to the main switch 87 between the battery 76 and the brake switch 88, the brake pedal 42 is moved to the stepping limit position. The starter 89 is operated from the battery 76 via the starter relay 91 only when the operation of removing the main gear lever 40 from the engine stop position 55d in the braking state of the stepped brake 25 is performed. The energization of the engine 7 is allowed, and the start operation of the engine 7 by the operation of the starter 89 based on the operation of the main gear lever 40 is possible.

In addition, even when the start operation of the engine 7 cannot be performed by energization of the starter 89 from the battery 76 via the starter relay 91 due to a failure of the starter relay 91 or the like. Since the operation of starting the engine 7 by the energization of the starter 89 from the battery 76 based on the operation of the switch 87 is possible, the operation of the main switch 87 causes the engine 7 to be started. Can be.

In addition, 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 the temperature of the engine coolant is set to an upper limit temperature (based on the output of the water temperature sensor 85). For example, when it detects that it exceeds 110 degreeC, even if the main gear lever 40 is located in the engine stop position 55d, by performing the above-mentioned engine start control and forcibly restarting the engine 7, It is configured to operate a cooling fan (not shown) that operates with power from the engine 7 to cool the engine 7 and the engine coolant.

As shown in FIG. 12, in the display ECU 83, the stop time integration means 83C which integrates the stop time of the engine 7 by engine stop control, and the total work time calculation means which calculates the total work time. 83D of integration time addition means are provided as a control program. In addition, in the vicinity of the meter panel 81, the reset switch 95 which consists of a momentary switch which outputs a reset command etc. to the operation time integrating means 83B of the display ECU 83, and pressing each time a press operation is performed, and pressurization. The display changeover switch 96 which consists of a momentary switch which outputs a display changeover command to the display control means 83A of the display ECU 83 is arrange | positioned every time operation is performed.

The running time integration means 83B accumulates the running time of the engine 7 obtained in the running time measurement process after receiving the reset command from the reset switch 95 in parallel with the above-described total running time integration processing. The reset operation time integration process is performed to find the engine operation time (an example of integration operation time) after the reset.

While the stop time integration means 83C detects the stop of the engine 7 by the engine stop control based on the outputs of the engine sensor 86 and the stop sensor 90, the engine by the engine stop control with a timer. A stop time measurement process for measuring the stop time of (7) is performed, and the stop time of the engine 7 obtained in the stop time measurement process performed each time the engine 7 is stopped by the engine stop control is integrated to the engine stop control. The total stop time integration process is performed to find the total stop time (an example of the integration stop time) of the engine 7. In addition, in parallel with the total stop time integration process, the engine stop time (integration stop time) after reset is accumulated by integrating the stop time of the engine 7 obtained in the stop time measurement process after receiving the reset command from the reset switch 95. The stop time integration process is performed after the reset to obtain an example of?

The total work time calculating means 83D is the main work time required for the main work such as the seeding work performed in the state in which the engine 7 is operated with the total operating time of the engine 7 determined by the uptime integration means 83B. The total stop time of the engine 7 by the engine stop control determined by the stop time integration means 83C is a subsidiary work necessary for assisting operations such as gathering, dispensing fertilizer, or eliminating fertilizer clogging, which are performed by stopping the main work. The total working time (an example of the total integration time) in consideration of the auxiliary working time required for the auxiliary work performed during the engine stop by the engine stop control that could not be obtained by adopting the engine stop control by summing these working hours as the working time. The total work time calculation process is performed. In addition, in parallel with the total work time integration process, the total engine operation time after reset is calculated by summing the engine operation time after reset determined by the operation time integration means 83B and the engine stop time after reset determined by the stop time integration means 83C. The total work time calculation process is performed after the reset to obtain an example of integration time.

The display control means 83A is based on the outputs of the engine sensor 86, the stop sensor 90, and the like, as the display ECU 83 is started by the operation from the OFF position to the ON position of the main switch 87. To start the automatic display switching control for automatically switching the display state of the auxiliary display unit 82C, and to switch the display state of the auxiliary display unit 82C based on the display switching command from the display switching switch 96. It is configured to perform display switching control.

As shown in FIG. 17, in the automatic display switching control, the display control means 83A firstly runs from the start of the automatic display switching control until a predetermined set time (for example, 2 seconds) elapses. The display state of the auxiliary display unit 82C is maintained in the total operation time display state indicating the total operation time of the engine 7 determined by the operation time integration means 83B (steps # 1, # 2). After that, when the set time has elapsed, it is determined whether the engine stop condition is satisfied (step # 3). In addition, since the conditions for engine stop here are the same as the conditions for engine stop in engine stop control, it describes simply as the conditions for engine stop.

When the condition for stopping the engine is satisfied, the display state of the auxiliary display portion 82C is switched to the ECO display state in which the letter "ECO" is displayed in the total operation time display state, and the main gear lever 40 The driver is notified that the engine stop control based on the operation to the engine stop position 55d can be executed (step # 4). If the engine stop condition is not satisfied, the display state of the auxiliary display unit 82C is maintained in the total operating time display state until the condition for engine stop is established, and the engine stop position 55d of the main gear lever 40 is maintained. The driver is notified that the engine stop control based on the operation in () is impossible.

After switching to the ECO display state, it is determined whether the operation position of the main gear lever 40 is the engine stop position 55d based on the output of the stop sensor 90 (step # 5), and the engine stop position. In the case of 55d, the display state of the auxiliary display unit 82C is set, and the total stop time of the engine 7 obtained by the character " ECO " For example, the display is switched to the ECO stop time display state to be switched and displayed every two seconds, and the driver is notified of the engine stop state by the engine stop control and the total stop time of the engine 7 by the engine stop control [Step # 6]. . If the engine stop position is not 55d, it is again determined whether the engine stop condition is satisfied [Step # 7], and if the engine stop condition is satisfied, the display state of the auxiliary display unit 82C is satisfied. Is returned to step # 5 while maintaining the ECO display state, and the control operation after step # 5 is performed. When the engine stop condition is not satisfied, the display state of the auxiliary display portion 82C is switched from the ECO display state to the total operating time display state, and is based on the operation of the main gear lever 40 to the engine stop position 55d. The driver is notified that the engine stop control cannot be executed (Step # 8). After that, the process returns to Step # 3 and the control operation after Step # 3 is performed.
