Description

Start control device and method of passenger rice transplanter, and passenger rice transplanter including start control device {Engine go-stop auto control system and methods of Saddle type rice transplanter and Rice transplanter containing the same}

The present invention relates to a start control device and method for a passenger rice transplanter, and more particularly, when the simulation is necessary to further supply during rice transplanting operation, the engine is automatically turned off by a simple operation other than a start key operation. The present invention relates to a starter control device and method for turning on the starter in a safe gas operation state without the risk of a safety accident such as a sudden start, and a passenger turner including a starter control device.

As a farming tool for transplanting seedlings grown in nails or seedling boxes into rice paddies, a rice seeding machine called a rice transplanter is widely used. Rice transplanters are divided into wheel type and float type according to the type of traveling device. The wheel type includes a moving rice transplanter having a structure in which a driver can ride, and the float type may be a walking rice transplanter for driving a rice transplanter while the worker walks upright.

Among these, the rice transplanter includes a self-propelled type driving gas, and a planting device connected to the rear of the driving gas so as to be lifted and lifted, and implanted into a planting target surface. The driving body is provided with a cockpit in which an engine is mounted, a driving wheel, a seat and steering wheel, and the planting device includes a mother table, a planting mechanism, and a float to stop the planting target surface.

Passenger rice transplanters are frequently shifted from low speed to high speed or from high speed to low speed, and the forward / reverse movement direction is changed. Accordingly, in order to increase the efficiency of shift operation during operation or driving, and also to increase the efficiency of gas operation, a hydrostatic transmission (HST) is generally adopted as a transmission.

Generally, the HST is composed of a variable displacement hydraulic pump that sucks hydraulic oil at a rotational force output by the engine and discharges the oil at a predetermined pressure, and a fixed displacement hydraulic motor that rotates with the hydraulic oil discharged by the hydraulic pump and outputs substantial driving power. By adjusting the inclined plate angle of the variable displacement hydraulic pump, it is possible to change the rotational speed (driving speed) and the rotational direction (forward / backward switching) of the fixed displacement hydraulic motor.

The output control of the HST, that is, continuously variable speed control in relation to the speed and the driving direction can be performed through the operation of the peripheral speed lever around the cockpit, and the stepping pedal is added to the footrest of the cockpit so as to be interlocked with the peripheral speed lever. The function considering the convenience of operation is realized to implement the speed and the forward and reverse shift by selecting and operating the main gear lever or the shift pedal according to the work situation.

The engine speed of the HST passenger rice transplanter can be set by pulling or pushing the hand axle lever disposed around the steering wheel, so that the peripheral speed is operated while the speed lever is operated at a desired speed setting position during the rice transplanting operation. The lever or shift pedal can be manipulated to change the speed and direction of the aircraft to suit your driving or working situation.

On the other hand, if additional simulation is required during the transplanting operation, the aircraft is moved to the center of the paddy field or at the edge of the paddy field, and then the start key is operated to additionally supply the seedling with the starter off, or the hand axel lever is It is common to supplement the hair while the engine is set in the idle state by operating in the idle position.

However, if you supply the hat with the ignition off with the ignition turned off, there is a hassle of turning on the ignition again by operating the key while the brake is in the brake state. In addition to the problem of exhaustion, there is a problem that unpleasant engine noise in the engine idle driving state increases worker fatigue.

In addition, when the engine is idle and the subsidiary lever is on the pavement, if the driver accidentally presses the shift pedal while moving out of the driver's seat to replenish the hair, the aircraft will suddenly move forward to inertia. There is a risk that the driver may be dislodged or fallen over the aircraft. This is because the shifting pedal and the fuel control system of the engine are connected by wires due to the rice transplanter structure.

In addition, the start control apparatus according to an aspect of the present invention includes an automatic start button for inputting an execution command for restarting the engine in a state in which the engine is stopped by the automatic engine stop control, and for restarting the engine through the automatic start button. It is determined whether the gas state at the time when the signal is input satisfies the auto start condition, and if the auto start condition is satisfied, control for restarting the engine may be executed by the controller.

In this case, the auto-start condition may be a case where the engine is stopped and the engine speed lever is operated at an idle speed (Idle rpm) position so that the idle state detection switch is switched on.

The auto start condition can also be set to the sleep mode by turning off the power supply to the electronics if the start is not resumed even after the set time (T2) has elapsed since the engine stopped by the engine auto stop control. It may further include a state.

In addition, when the engine speed lever moves out of the idle rpm position and the idle state detection switch is switched off by the driver's shift pedal at a time when an execution command for restarting the engine is input through the automatic start button. The controller may determine that the automatic start condition is not satisfied and stop the execution for restarting the engine, and display the result through the instrument panel so that the driver recognizes the reason for stopping the engine restart.

According to another aspect of the present invention, there is provided a passenger rice transplanter comprising a start control device according to the above aspect.

Also according to another aspect of the present invention,

(a) determining whether the gas operation state at the time when the execution command for entering the engine auto stop mode is entered satisfies the auto stop condition;

(b) if the automatic stop condition is satisfied, executing control for automatic engine stop when the set time T1 elapses with the automatic stop condition satisfied;

and (f) if the execution command for engine restart is input in step (c) or (e) and the gas state at that time satisfies the auto start condition, executing control for engine restart. Provides a starting control method for the rice transplanter.

Here, in the step (a), the engine is started when the execution command for entering the engine auto stop mode (Go-Stop mode) is input, and the operation position of the moving lever detected by the moving lever position sensor is lowered or moved. When the shift from the position to the neutral position is detected, and the engine speed lever is operated to the idle rpm position, the idle state detection switch may be determined to satisfy the automatic stop condition. .

Further, in the step (b), the engine can be stopped by controlling the engine stop solenoid of the fuel control device to cut off the fuel supply.

In addition, the step (b) may include a step of recognizing, to the driver that the start-up auto-stop state by the auto-stop control through a specific lamp flashes and an alarm sound of the instrument panel together with the engine auto-stop control.

Further, in the step (c) or (e), the engine is stopped at the time when the execution command for engine restart is input and the engine speed lever is operated to the idle rpm position so that the idle state detection switch is switched on. In case of (On), it may be determined that the auto start condition is satisfied.

Also, in the step (d), if there is no execution command input for restarting the engine even after the set time T2 has elapsed, the start request message is transmitted to the driver through a specific lamp flashing and an alarm sound before the power is turned off. Process may be included.

According to the start control apparatus and method for a passenger rice transplanter according to an embodiment of the present invention, the engine can be automatically stopped by a simple operation other than the start key. Accordingly, it is possible to reduce fuel consumption by preventing unnecessary fuel consumption while replenishing the wool, and solve the problem that the engine noise increases the worker's fatigue when the wool is additionally supplied without turning off the engine.

In addition, in the prior art, even if the start is turned off to save fuel, the key can be restarted by operating the key with the brake pressed upon restarting. If it satisfies, the engine can be restarted with a simple switch operation, which eliminates the inconvenience of restarting after the engine is stopped automatically.

In addition, if the engine does not have a command for restarting or restarting after a predetermined time has elapsed after the engine auto-stop mode is executed, the power cut-off unit is operated to supply power to the electrical equipment. The supply is automatically shut off to prevent battery drain or discharge due to power supply in the Key_on state.

In addition, when the engine is restarted after the engine stops in the auto stop mode (Go-Stop mode), the automatic start condition (engine governor lever operated at the idle rotational speed position) can be prevented to prevent sudden start and subsequent safety accidents. This is done. As a result, it is possible to reliably prevent sudden start and subsequent safety accidents that may occur when the engine is restarted after the engine stops automatically.

In the description with reference to the accompanying drawings, the same reference numerals are assigned to the same components, and duplicate description thereof will be omitted. In the following description of the present invention, if it is determined that the detailed description of the related known technology may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a configuration diagram of a rice transplanter start control device according to an aspect of the present invention.

Referring to FIG. 1, a start control apparatus according to an aspect includes a Go-Stop Switch 100 to which an execution command for entering an engine auto stop mode is input. In addition, the idle lever position sensor 110 for detecting the operation position of the moving lever 85 provided for planting device 4 (see Fig. 3) lifting operation and outputs the idle (Idle) state information of the engine 5 An idle state detection switch 115 is included.

The Go-Stop Switch (100) is configured separately from the main Start-Key, and a run command for entering the Auto-Stop mode is entered so that the engine can be automatically stopped under operating conditions other than the Start-Key. do. The automatic stop switch 100 may be installed at a suitable position around the driver's seat, and an execution signal for entering the automatic stop mode may be generated by the controller 120 according to the operation of the automatic stop switch 100.

The automatic stop switch 100 may be a toggle type switch that maintains the switch on state until the off operation when the switch is on once, but is not limited thereto. All kinds of known switches selectable by those skilled in the art may be used, including push button tpye, rotary type, touch type, and the like.

The moving lever position sensor 110 detects an operation position of the moving lever 85. The moving lever 85 is connected to the actuator for lifting the planting device in the rear of the body to drive the actuator through the moving lever 85, and thus the planting device to a desired height, for example, rising, neutral, It can be located in the lowering and cutting positions.

The moving lever position sensor 110 preferably detects the rotational displacement of the moving lever 85 based on the neutral position to detect the operation position of the moving lever 85. This includes a configuration in which mechanical on / off type switches are installed one by one, and all known types of detection sensors (Ex. Variable) detect a position of the moving lever 85 in a contact / non-contact manner and output a signal. Resistance type, optical sensor, etc.).

The idle state detection switch 115 is switched on / off according to the position of the engine 5 and the speed control lever 50 connected to the shift pedal 87 and the hand axle lever 81 by a cable or a link, and thus the idle state of the engine 5 is switched. (Idle) Outputs status related information. Preferably, when the governing lever 50 is in a position for maintaining the engine speed of the engine 5 in the idle state (when the shift pedal and the hand axle lever are not operated), the control unit 120 switches on the corresponding signal. ) May be configured to output.

More specifically, when the speed change lever (50) or the hand axle lever (81) is operated, the governing lever (50) is switched off when moving from the idle position to the position of increasing the engine speed (5), It may be an on / off type mechanical switch that is switched on when there is no operation of the shift pedal 87 and the hand axle lever 81. Of course, it is possible to replace any known type of sensor that detects the operation of the governing lever 50 in a contact or non-contact manner.

The predetermined detection information by the moving lever position sensor 110 and the idle state detection switch 115 is transmitted to the control unit 120. The controller 120 determines whether the current operating state of the moving lever 85 and the engine 5 speed lever 50 satisfies the automatic stop condition of the engine 5 from the predetermined detection information transmitted from the sensor and the switch. . If the condition is satisfied, control for automatic engine stop is executed.

The controller 120 performs current control of the engine stop solenoid 132 of the fuel control device 130 when a predetermined condition for engine automatic stop is satisfied. Specifically, by controlling the value of the control current supplied to the engine stop solenoid 132 of the fuel control device 130 to move the spool of the fuel control device 130 to the fuel supply blocking side engine 5 ) Will stop.

The automatic stop condition of the engine 5 is preferably that the operating position of the moving lever 85 detected through the moving lever position sensor 110 in the state of starting is moved from the descending or moving position to the neutral position. When the shift pedal 87 and the hand axle lever 81 are not detected, that is, the engine 5 speed lever 50 is operated at an idle speed (Idle rpm) position, the idle state detection switch 115 is operated. ) May be switched on.

If there is no operation of the shift pedal 87 and the hand axle lever 81, there is a high possibility that there is no driving or work intention, and in addition, if the planting device (orientation part) is operated at a neutral position suitable for supplying all, the operator may not know. The aircraft can be viewed as stationary for further replenishment. Therefore, when the idle rotational position operation of the governing lever 50 and the neutral position operation of the moving lever 85 are satisfied at the same time, it can be determined that the automatic stop condition is satisfied.

When feeding the seedlings, the planting equipment should be placed in the lowered position (the position where it touches the ground) so that it can be fed in a natural posture without great effort. On the contrary, when the planting apparatus is placed in an elevated position and the hair is supplied, the posture is unnatural and the fatigue of the worker increases because the worker must hold the hair growth box and closely adhere the hair growth box to the bottom of the mother mount to prevent the colonization during transplanting.

Therefore, if the moving lever 85 is operated in the position to raise the planting apparatus can be regarded as a normal working behavior. In other words, if the moving lever 85 is operated in the ascending position, it is highly likely to be a normal work behavior, so even if there is no operation of the speed lever 50 in the state of switching to the automatic stop mode by the automatic stop switch 100 operation. For example, the engine stops automatically.

Even in the automatic stop mode, even if the operating state of the aircraft satisfies the automatic stop condition, it may be possible to switch the gas to the working state in a short time depending on the situation. In this case, if start is turned off by automatic stop control, it cannot start or work quickly. Therefore, even if the auto stop condition is satisfied, it is preferable that the engine auto stop control is executed only after the set time T1 has elapsed.

The engine auto stop by the engine auto stop control is different from the engine 5 stop by the normal start key off. For example, a normal start-off with the ignition key is in the power-off state, but the engine auto stop is an arbitrary start-off in the key-on state rather than the ignition with the ignition key. You need to be aware of the situation.

As a method of recognizing the driver that the driver is in the auto stop state by the automatic stop control, a method of acoustically recognizing the corresponding information through a sound signal, a method of visually recognizing the information through the display device, and the like may be considered. Preferably, it may be configured to recognize the driver that the auto stop state by the auto stop control through the specific lamp flashing of the instrument panel 90 and the alarm sound of the buzzer 95.

When the engine 5 stops due to an auto stop signal that the control unit 120 outputs to the engine stop solenoid 132 during engine auto stop control, as described above, a normal engine due to key-off (5) Since the engine 5 stops in the key-on state instead of the stop state, electricity flows through the electric circuit. Therefore, when the time is longer, power consumption may accumulate and the battery 170 may be discharged.

The power cut-off unit 160 is applied as a means for preventing the battery 170 from being discharged due to the engine 5 being stopped in the key-on state. The power cut-off unit 160 is activated when the engine is not restarted for a predetermined time after the engine stops automatically, thereby preventing the battery 170 from discharging. Preferably, after the set time T2, the power supply of the battery 170 to the electric appliance 180 that is operated under the control of the controller 120 and consumes current may be cut off.

The power cut-off unit 160 may be a relay disposed on a power supply circuit for supplying power of the battery 170 to the electronic device 180 and controlled to control the power supply under the control of the controller 120. Preferably, when the start is not restarted to pass the set time T2, the driver may be alerted by a specific lamp blinking on the instrument panel 90 and the alarm sound of the buzzer 95 before the power is cut off through the power cutoff unit 160. You can also send a start request message to the server.

Reference numeral 190 denotes an automatic start button. An execution command for restarting the engine 5 in the state in which the engine 5 is stopped by the engine auto stop control may be input through the auto start button 190. The automatic start button 190 may be disposed at a position at which the driver's operation around the driver's seat is easy. Preferably, it may be provided as a push button type in the main gear lever for the forward / neutral / reverse main gear operation.

When a signal for restarting the engine 5 is input according to the driver's intended operation of the auto start button 190, the controller 120 determines whether the gas state at the time when the signal is input satisfies the auto start condition. do. When the auto start condition is satisfied, a predetermined signal (Auto Start Signal) is simultaneously output to the engine stop solenoid 132 of the starter motor 140 and the fuel control device 130 to perform a predetermined control so that the start can be turned on again. do

The auto start condition may include a gas operating state that can reliably prevent sudden start and subsequent safety accidents upon restarting the engine 5. Preferably, in the state where the engine 5 is stopped, the governing lever 50 for setting the engine 5 rotational speed is maintained in an operated state at an idle rotational speed so that the idle state detection switch 115 is switched on. (On) may be the case. That is, the shift pedal 87 and the hand axle lever 81 may not be operated.

In the auto start condition, the power cut-off unit 160 is operated because the start is not restarted so that the set time T2 passes from the time when the engine 5 is stopped by the engine auto stop control, and the gas state slips accordingly. It may also include a state that is switched to the sleep mode. That is, it may include a case where the electric circuit is switched to the sleep mode by the power cut off by the power cut-off unit 160.

When the execution command for restarting the engine 5 is input through the automatic start button 190, the speed control lever 50 is operated by the shift pedal 87 (or the hand axle lever 81) by the driver. Is out of the idle rpm position, that is, when the idle state detection switch 115 is switched off, the control unit 120 determines that the auto start condition is not satisfied, and restarts the engine 5. Stop execution for

The switch-off of the idle state detection switch 115 means that the shift pedal 87 (or the hand axle lever 81) has been operated. When restarting is performed in this state, the gas sudden start and the corresponding safety accident are performed. Because it can occur. When the engine 5 is not started because the automatic starting condition is not satisfied, the reason may be accurately recognized by transmitting the reason to the driver through the instrument panel 90 or the speaker.

The controller 120 may determine whether to start the engine 5 from the charging signal of the battery 170. Since the charging current is supplied to the battery 170 by driving the alternator 150 in the state of starting, a charging signal of a predetermined value or more is generated, and the ground (GND, battery 170 charging signal of the battery is turned off). This is because a charging signal of Off) or low level (DC + 3V or less) is input.

Engine 5 rotation speed detected by the pick-up sensor (sensor detecting engine 5 rotation speed signal using a phase terminal of the alternator) when it is confirmed that the engine 170 is started by the charging signal of the battery 170 If the number is, for example, 800 rpm or more, the controller 120 protects the starter motor 140 from overrun by ignoring the input even if the driver keeps pressing the auto start button 190.

The control unit 120 also, if it is confirmed that the start-up is stable from the battery 170 charging signal or the detection signal by the pickup sensor, the control signal for releasing the power off state by the power cut-off unit 160 In this way, power may be normally supplied to each electric appliance 180. That is, the state of the electric circuit in the sleep mode is switched to the wake up mode.

Hereinafter will be described in connection with the operation of the start control device for the control process for the automatic stop and automatic start of the rice transplanter engine (5) performed by the start control device as described above.

2A and 2B are control logics applied for automatic start control through the above-described start control device, which will be described with reference to the accompanying drawings.

In the automatic start control, first, the information provided by the detection means is automatically stopped when the execution command for entering the engine auto stop mode (Go-Stop Switch) 100 is input through the auto-stop switch 100. The control unit 120 determines whether the Off condition is satisfied (S100). The information provided by the detection means may include information provided by the moving lever position sensor 110 and the idle state detection switch 115.

Preferably, it is detected that the operating position of the moving lever 85 detected through the moving lever position sensor 110 in the state where the engine 5 is being started is moved from the descending or moving position to the neutral position, and the engine (5) When the idle lever 50 is operated at an idle rpm position and the idle state detection switch 115 is switched on, it may be determined that the automatic stop condition is satisfied.

When the automatic stop condition is satisfied, preferably, control for engine automatic stop is executed when the set time T1 elapses with the automatic stop condition satisfied (S200). Specifically, when the set time T1 elapses while the auto stop condition is satisfied, an auto stop signal is output from the control unit 120, and the output auto stop signal is an auto stop signal. It is transmitted to the engine stop solenoid 132 of the control device 130.

By operating the engine stop solenoid 132 by an auto stop signal, the spool in the fuel control device 130 is moved to block the fuel supply, and the engine 5 is stopped by stopping the fuel supply. That is, when the shift pedal 87 (or the hand axle lever 81) is not operated and the moving lever 85 is operated at a specific position, it is determined that the automatic stop condition is satisfied, and a specific signal is sent to the fuel control device 130. The engine 5 is stopped.

If the operating state of the governing lever 50 and the moving lever 85 connected to the shift pedal 87 does not satisfy the automatic stop condition, the process is terminated without further control for automatic stop. For example, when the shift pedal 87 is not operated but the moving lever 85 is not operated at a specific position or the moving lever 85 is located at a specific position but the pedal pedal 87 is pressed (idle state detection switch). (115) Off) The process ends without further progress.

Along with the engine automatic stop control in step S200, a specific lamp of the instrument panel 90, for example, the "automatic start off" or flashing of the relevant symbol and buzzer (95) to generate an alarm sound by the automatic stop control It may also include a step of recognizing the driver that the start-up automatic stop state. Of course, there is also a method of mounting a speaker to deliver the message in the form of a voice signal.

Whether the engine auto stop is executed by the auto stop signal can be determined from the charge signal of the battery 170 or the engine 5 revolution signal by the pickup sensor. In the case of the battery 170 signal, since no charging signal is input or a charging signal of low level (DC + 3V or less) is input when the engine is turned off, the engine 5 performs predetermined control (automatic stop control only by the battery 170 charging signal). ) To determine if it stopped successfully.

If the execution command for restarting the engine 5 is input before the set time T2 has elapsed while the engine 5 is stopped by the engine auto stop control, the controller 120 determines that the gas state at that time is an auto start condition. It is determined whether to satisfy (S300). On the other hand, if there is no execution command input for restarting the engine 5 even after the set time T2 has elapsed, the circuit state is switched to the sleep mode by cutting off the power supply to the electronic device 180 (S400).

When the engine 5 is stopped by an auto stop signal output by the controller 120 because a predetermined condition for engine auto stop is satisfied, the engine 5 is stopped normally due to key-off. Since the engine 5 is stopped at the key-on state, the electric parts 180 constituting the aircraft are continuously supplied with electricity through the battery 170. This is because the 170 may be discharged.

That is, after execution of the automatic stop, the control unit 120 counts the time T2 from the time when the automatic stop is executed, and when the predetermined time T2, when the time from the time when the automatic stop is executed, is preset, elapses, By outputting a power cut signal to the power cut-off unit 160 to cut off the power supply to a specific component to prevent the battery 170 is discharged.

In some cases, when there is no execution command input for restarting the engine 5 even though the setting time T2 has elapsed in step S400 (when the automatic start button 190 is not operated during the setting time T2), Prior to switching to the sleep mode through power off, a specific lamp flashes and the buzzer 95 of the instrument panel 90 may generate an alarm sound to transmit a start request message to the driver.

When there is no execution command for restarting the engine 5 after passing the start request message through the specific lamp flashing through the instrument panel 90 and the alarm sound through the buzzer 95 and passing the setting time T3 again. (If there is no operation of the automatic start button 190 during the set time (T3)), through the instrument panel 90 may be switched to the sleep mode by shutting off the power after the flashing lamp for a certain time.

When the execution command for restarting the engine 5 is input even when the system is in the sleep mode (when the automatic start button 190 is operated), it is determined whether the gas state at that time satisfies the automatic starting condition ( S500). If the driver turns off the start key while in the sleep mode, the process is terminated in that state. Otherwise, the process is kept in the sleep mode.

On the other hand, if the execution command for restarting the engine 5 is input in step S300 or S500 and the gas state at that time satisfies the auto start condition, control for restarting the engine 5 is executed (S600). Preferably, when the engine 5 is stopped and the idle state detection switch 115 is switched on at the time when the engine 5 restart command is input, the engine 5 is determined to be satisfied. The control for restart is executed.

If the gas state does not satisfy the auto start condition in step S300 or S500 (when the idle state detection switch 115 is switched off), the controller 120 determines that the auto start condition is not satisfied. In addition, the execution for stopping the engine 5 may be stopped, and the instrument panel 90 may be displayed so that the driver recognizes the reason for restarting the engine 5.

Meanwhile, in step S600 for restarting the engine 5, the controller 120 outputs an auto start signal, and simultaneously outputs the output signal to the solenoid of the fuel control device 130 and the starter motor 140. To pass. Accordingly, the spool in the fuel control device 130 is moved to the side to allow the fuel supply and the starter motor 140 is driven to eventually start up again.

When the engine is restarted (at least the engine rotation speed) detected by the battery 170 charging signal or a pickup sensor (a sensor for detecting the engine rotation speed signal using the phase terminal of the alternator) at restart. It is possible to determine whether the start is normally performed, and when the start is normally performed, the controller 120 may ignore the input even if the driver keeps pressing the auto start button 190.

On the other hand, prior to confirming that the start-up stably from the battery 170 charging signal or the detection signal by the pickup sensor, a process of outputting a control signal for releasing the power off state in the step S400 is performed, Accordingly, power may be normally supplied to each electric appliance 180. That is, the state of the electric circuit in the sleep mode is switched to the wake up mode.

And a start control device for performing control. Since the start control apparatus has been described above, duplicated descriptions will be omitted and the overall configuration and component arrangement will be briefly described.

Referring to FIGS. 3 to 10, the rice transplanter is largely composed of a self-propelled traveling body 3 having a front wheel 1 and a rear wheel 2, and a planting apparatus 4 connected to the rear of the traveling body 3 so as to be lifted and lowered. do.

Include.

The power generated by the engine 5 mounted on the traveling body 3 is transmitted to the transmission 7 via the first stepless speed change through the HST 6 at the rear of the engine, and the secondary through the transmission 7. After the sub-shift part is provided to the rear wheel (2) as a driving power through the driving motor shaft (mido) extending to the rear axle, and the other part through the moving shaft (not shown) after the weekly shift in the transmission planting device ( 4) is delivered.

The HST 6 may be composed of a variable displacement hydraulic pump driven by the power of the engine 5 and a fixed displacement hydraulic motor that rotates with hydraulic oil provided by the hydraulic pump and outputs substantial driving power. It is possible to change the output (rotation speed) of the fixed displacement hydraulic motor by adjusting the angle of the inclined plate of the variable displacement hydraulic pump connected to the speed lever or the shift pedal.

In the traveling body 3 between the front wheel 1 and the rear wheel 2 of the traveling body 3, a driver's seat 8 for operating the body is provided. The driver's seat 8 includes a steering wheel 80 for gas steering and a hand axle lever 81 for adjusting the output of the engine, a peripheral speed lever 82 and a shift pedal 87 for continuously variable operation, and a secondary part. Sub-shift levers (not shown) and the like for shifting are arranged at positions easy to operate around the seat 83.

When one of the main gear lever 82 and the shift pedal 87 disposed in the driver's seat 8 is operated, the output of the HST 6 can be adjusted accordingly, and the periphery of the steering wheel 80 is the dashboard panel. It is surrounded by (9). The dashboard panel 9 is provided with an instrument panel 90 for displaying various information (speed information, inspection-related information, electronic equipment operation information, etc.), various switches and buttons for starting and electronic equipment operation.

The switches may include the above-described Go-Stop Switch 100. The automatic stop switch 100 is configured separately from the main start key (start switch 105), and may be provided in the form of an example (see FIG. 6) and a toggle switch. Of course, it is not limited to the toggle switch type, the hand axle lever 81 and the moving lever 85 for the planting device lifting operation can be disposed on the right side of the steering handle (80).

As shown in FIG. 7, the above-described moving lever detects an operating position (rising, neutral, falling, moving position, etc.) of the moving lever around the moving lever 85 and transfers the detected information to the control unit 120. The position sensor 110 may be disposed, and the hand axle lever 81 and the shift pedal may be disposed on the governing lever 50 of the fuel control device 130 disposed at one side of the engine 5 as shown in FIGS. 8 and 9. 82 may be interlockedly connected to each other through an interlocking link (not shown) and the respective wire cables C1 and C2.

In addition, the governing lever 50 may be provided with an idle state detection switch 115 which is switched on / off according to the operating position of the governing lever and outputs idle state information of the engine. 115 may be configured to be switched on when the governing lever 50 is operated at a position to set the engine speed to the idle, and to be switched off when in the other position.

The main gear lever 82 may be installed adjacent to one side of the seat 83 (see FIG. 10), and mechanically connected to the hand axle lever 81 for setting the engine speed (output) through an interlocking link or a cable. Can be connected. Preferably, the hand axle lever 81 may be connected to each other such that the hand axle lever 81 is moved to a position for setting the engine speed to the idle in conjunction with the movement of the neutral position of the main gear lever 82.

The main gear lever 82 may be provided with the aforementioned automatic start button 190 in which an execution command for restarting the engine is input in a state in which the engine is stopped by the automatic engine stop control. Of course, the position of the automatic start button 190 is not limited to the peripheral speed lever. In consideration of the most frequent use of the main gear lever among the various operation levers, it may be disposed in another position as a consideration for convenience of operation.

According to the embodiment of the present invention as described above, the engine can be automatically stopped by a simple operation other than the start key. Accordingly, it is possible to reduce fuel consumption by preventing unnecessary fuel consumption while replenishing the wool, and solve the problem that the engine noise increases the worker's fatigue when the wool is additionally supplied without turning off the engine.

In addition, in the prior art, even if the start is turned off to save fuel, the key can be restarted by operating the key with the brake pressed upon restarting. If it satisfies, the engine can be restarted with a simple switch operation, which eliminates the inconvenience of restarting after the engine is stopped automatically.

In addition, if the engine does not have a command for restarting or restarting after a predetermined time has elapsed after the engine auto-stop mode is executed, the power cut-off unit is operated to supply power to the electrical equipment. The supply is automatically shut off to prevent battery drain or discharge due to power supply in the Key_on state.

In addition, when the engine is restarted after the engine stops in the auto stop mode (Go-Stop mode), the automatic start condition (engine governor lever operated at the idle rotational speed position) can be prevented to prevent sudden start and subsequent safety accidents. This is done. As a result, it is possible to reliably prevent sudden start and subsequent safety accidents that may occur when the engine is restarted after the engine stops automatically.

In addition, the current status of the aircraft operation or engine status, and the reason for the inability to start the engine on the instrument panel, etc. By notifying the driver through the alarm sound, the driver can recognize the current situation accurately and can quickly follow up or respond.
