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.

In general, HST is a variable displacement hydraulic pump driven by the rotational force output by the engine to suck hydraulic fluid and discharge it at a predetermined pressure, and a fixed displacement hydraulic motor that rotates with the hydraulic oil discharged by the hydraulic pump to output substantial driving power. It is configured to change the inclination plate angle of the variable displacement hydraulic pump to change the rotational speed (driving speed) and the rotational direction (forward / backward switching) of the fixed displacement hydraulic motor.

HST output control, 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, the stepped peripheral speed pedal is added to the footrest portion of the cockpit to be interlocked with the peripheral speed lever. In this case, the function considering the convenience of the operation is reflected to implement the speed and the forward and rearward shift by selecting and operating the peripheral speed lever or the peripheral speed pedal according to the situation.

The engine speed of the HST passenger rice transplanter can be set by pulling or pushing the governing lever disposed around the steering wheel, and thus the peripheral gear lever is operated in a state in which the governing lever is operated at a desired rotational speed setting position during the cutting operation. You can change the speed and direction of the aircraft as desired to suit your driving or working situation.

On the other hand, if additional simulation is required during the transplanting operation, move the aircraft to the mother supply site at the edge of the paddy field, and then operate the key to turn off the engine or set the engine to idle using the governor lever to supply the mother. It is common to do However, when the start is turned off using the key, there is a problem in that it is necessary to turn on the start again by operating the key while the brake is pressed, and when the engine is set in the idle state, fuel is unnecessarily consumed while the mother feeding is performed.

1 is a block diagram of a passenger rice transplanter engine control apparatus according to an aspect of the present invention, Figure 2 is an enlarged view showing a side speed lever side constituting a passenger rice transplanter engine control apparatus according to an aspect of the present invention.

According to an aspect, an engine control apparatus includes a self-propelled traveling gas and a lifting rice transplanter including a lifting type planting device provided at a rear of the traveling gas and mounted on a mother mounting table and implanted on a planting target surface, wherein The engine is automatically stopped or restarted according to the operation state of the speed pedal, thereby preventing fuel consumption and eliminating inconvenience caused by starting on / off.

1 and 2, the engine control device is switched on when the main gear lever 82 is operated at a specific position to output a predetermined electric signal to the controller 120 for stopping the engine. It includes a stop signal output means 100. In addition, a pedal operation detecting means 110 is switched on when the main gear pedal 87 is operated to output information on whether the main gear pedal 87 is operated to the control unit 120.

The stop signal output means 100 is physically connected with the main gear lever 82 when the main gear lever 82 is operated at a specific position (engine stop position ES), for example, as illustrated in FIG. 2. The internal switch circuit contact state is switched by the contact, and accordingly, the external switch circuit may be a micro switch configured to transmit power supplied from the outside to the controller 120 in the form of a predetermined electrical signal.

Of course, the peripheral gear lever 82 is switched on when operated at the specific position, including a mechanical on / off type switch that is switched to the automatic switch off (Off) state when out of the specific position, It may include all types of signal output devices such as a variable resistance method or an optical structure sensor that detects the movement of the speed lever 82 in a contact or non-contact manner and outputs a predetermined electrical signal.

The pedal operation detecting means 110 is also an on / off type mechanical type that is switched on when the main gear pedal 87 is operated and switched off when there is no operation of the main gear pedal 87. In addition to the switch, all types of known sensors such as a variable resistance method or an optical structure sensor may be included to detect an operation of the main gear pedal 87 in a contact or non-contact manner and output a predetermined electrical signal.

The control unit 120 transmits predetermined detection information by the stop signal output unit 100 and the pedal operation detection unit 110. The control unit 120 determines whether the current operation state of the main gear lever 82 and the main gear pedal 87 satisfies a condition for the automatic stop or restart of the engine from the predetermined detection information transmitted from the detection means. . If the condition is satisfied, the control command for the automatic engine stop or restart is output.

The controller 120 preferably transmits a specific signal (Auto Stop Signal) to the fuel supply device 130 having a solenoid structure to control the fuel supply when a predetermined condition for automatic stop or restart of the engine is satisfied. 150 or stops or outputs a specific signal (Auto Start Signal) to the starter motor 140 and the fuel supply device 130 at the same time to perform a predetermined control so that the start can be turned on again.

The predetermined condition for the automatic stop of the engine 150 is that the main gear lever 82 is operated to a specific position (ES) in a state where there is no operation of the main gear pedal 87 (the pedal operation detecting means is switched off), and a stop signal is output. The means 100 may be in a switched-on state, and a predetermined condition for restarting is that the main gear lever 82 is out of a specific position in a state in which there is no operation of the main gear pedal 87 and stop signal output means ( 100 may be switched off.

Specifically, when the main gear lever 82 is operated at a specific position in a state where there is no operation of the main gear pedal 87 (pedal operation detecting means switch off), the stop signal output means 100 is switched on. An auto stop signal for automatically stopping an engine is output from the controller 120, and the output auto stop signal is transmitted to the fuel supply device 130.

Accordingly, the spool in the fuel supply device 130 is moved to block the fuel supply and the fuel supply to the engine 150 is cut off, so that the engine stops. That is, when the main gear pedal 87 is not operated and the main gear lever 82 is located at a specific position, the control unit 120 determines that the performance condition for the automatic engine stop is satisfied and specifies the fuel supply device 130. Sending a signal allows the engine to stop.

On the contrary, in the state in which there is no operation of the main gear pedal 87 (pedal operation detecting means switch off), the main gear lever 82 is moved out of a specific position by the user operation and the stop signal output means 100 is switched off. When switched, an auto start signal for automatically starting the engine is output from the control unit 120 and transmitted to the fuel supply device 130 and the starter motor 140.

Accordingly, the spool in the fuel supply device 130 is returned to the side to allow the fuel supply and the starter motor 140 is driven, so that the engine 150 moves again. That is, when the main gear pedal 87 is not operated and the main gear lever 82 is out of a specific position (ES), the control unit 120 determines that the performance condition for the automatic engine start is satisfied and the fuel supply device 130 is operated. And a specific signal to the starter motor 140, so that the start can be turned on again.

When the engine 150 is stopped by an auto stop signal output by the control unit 120 because a predetermined condition for engine auto stop is satisfied, the key on is not an engine stop due to key-off. Since the engine is stopped in the key-on state, electricity is continuously supplied to the electric circuit constituting the vehicle through the battery 170. Therefore, when the time is long, the battery 170 may be discharged.

Accordingly, the engine control device according to an aspect of the present invention is provided with a power supply blocking means 160. The power supply blocking unit 160 prevents the battery 170 from being discharged by cutting off the power supply to a specific part after a predetermined time elapses after the engine stops automatically. Preferably, the controller 120 operates by a predetermined electric signal to block the power supply of the battery 170 to the electrical appliance 180 that consumes current in the key-on state.

The power supply blocking unit 160 is preferably disposed on a power supply circuit for supplying power of the battery 170 to the electronic device 180 and operated under the control of the controller 120 to interrupt the power supply (Power cut). relay). At this time, if the relay is not started for a predetermined time after the engine is automatically stopped, the relay is switched on by a power cut signal output by the control unit 120 to supply power to the battery 170 to the electronic device 180. Block it.

Along with the power cut off through the power supply blocking means 160, the battery 170 discharge-related information may be displayed to be recognized by the user through a predetermined display means. At this time, the display means, the instrument panel 90 having a specific symbol lamp to visually display the discharge information of the battery 170 after a predetermined time after the engine automatic stop and the information about the discharge of the battery 170 in the form of a predetermined warning sound. An output buzzer 95 may be included.

The controller 120 determines the engine starting state from the charging signal of the battery 170. Since the charging current is supplied to the battery 170 by driving an alternator (not shown) in a startup state, a charging signal of a predetermined value or more is generated, and in a state in which the startup is turned off, the ground (GND, battery charging signal off) or low level ( Charge signal of DC + 3V or less) is input. Therefore, the engine start state can be determined using only the battery charging signal.

When it is confirmed that the engine 170 is started from the charge signal (when the battery 170 charge signal returns to normal as the engine start control through the automatic start signal output), the control unit 120 outputs the engine restart. The auto start signal is turned off and the power cutoff signal is stopped so that power can be supplied to the electric appliance 180 which consumes current.

On the other hand, the governing lever 81 for setting the rotational speed of the engine 150 may be mechanically connected through the interlocking link or cable 89 so as to be linked to the movement of the peripheral speed lever 82. Preferably, the speed governing lever 81 is moved to a position for setting the engine speed to the idle (Idle) in conjunction with the movement of the neutral speed (N) of the main speed lever 82, neutralizing the main speed lever 82 It is good to keep the engine speed at idle (rpm_min) during operation.

In order to automatically stop the engine, the governing lever 81 which sets the engine speed in association with the operation of moving the main gear lever 82 to the specific position (ES) via the neutral position sets the engine speed in the idle. If it is moved to the position that is, when the engine is automatically restarted after the engine stops because it is possible to prevent the sudden start and the safety accidents that occur when restarted in the state set in the high rotation area.

On the other hand, as shown in FIG. 2, the specific position ES at which the main gear lever 82 is positioned for executing the engine auto stop is branched from the neutral position N of the predetermined main gear lever 82. The main gear lever 82 moved along the stop operation path 200 extending in the form of the engine is finally positioned, and the engine stop provided with the stop signal output means 100 for outputting a predetermined auto stop and start signal. Location ES.

The stop operation path 200 preferably includes a first direction operation path 210 and an end portion of the first direction operation path 210 that form a lever movement path in a horizontal direction from the neutral position N to the left or right side. It may be a configuration including a second direction operation path 220 to form a lever movement path in a direction perpendicular to the first direction operation path 210, wherein the engine stop at the end of the second direction operation path 220 The position ES may be set.

3 is a control logic applied for automatic engine control through the engine automatic control apparatus according to an aspect of the present invention. Referring to FIG. 3 and the accompanying drawings, the engine automatic control process performed by the engine automatic control apparatus will be described in connection with the operation of the engine automatic control apparatus described above.

In engine automatic control, first, the controller 120 determines whether the detection information provided by the detection means satisfies a specific condition. At this time, the detection information is preferably a pedal operation for detecting whether the stop signal output means 100 for outputting a predetermined electric signal and the main speed pedal 87 according to the operation position of the main speed lever 82 described above. It may include information provided from the detection means 110.

Specifically, in the state where there is no operation of the main gear pedal 87 (the pedal operation detecting means 110 is switched off), the main gear lever 82 is operated to a specific position (engine stop position, ES) to stop signal output means 100. ) Is switched on, an auto stop signal for automatically stopping the engine is output from the controller 120, and the output auto stop signal is output to the fuel supply device 130. Delivered.

The spool in the fuel supply device 130 moves to block the fuel supply by the auto stop signal, and the fuel supply to the engine is cut off, and the engine is stopped. That is, when the main gear pedal 87 is not operated and the main gear lever 82 is located at a specific position, the control unit 120 determines that the performance condition for the automatic engine stop is satisfied, and thus the specific signal is supplied to the fuel supply device 130. To stop the engine.

If the operation state of the main gear lever 82 and the main gear pedal 87 does not satisfy the condition of outputting the auto stop signal, the process is terminated without output of the auto stop signal. That is, when the main gear lever 82 is not operated to a specific position (engine stop position, ES), or the main gear lever 82 is located at a specific position but the main gear pedal 87 is pressed (pedal operation detection switch On) The process is terminated without further progress.

Whether the engine stops automatically by the auto stop signal can be determined from the charging signal of the battery 170. Since the charging signal of ground (GND, battery charging signal off) or low level (DC + 3V or less) is input when the engine is turned off, the engine is normally controlled through a predetermined control (automatic stop control) via the battery 170 charging signal. You can determine if it is stopped.

When the engine is stopped by an auto stop signal output by the controller 120 because a predetermined condition for engine auto stop is satisfied, the key-on is not an engine stop due to key-off. Since the engine stops in the on state, electricity is continuously supplied to some of the electric appliances 180 constituting the vehicle through the battery 170, and the battery 170 may be discharged when the time is long.

Accordingly, after executing the engine auto stop, the controller 120 counts the time T1 from the time when the auto stop is executed, and a predetermined time T2 in which a time from the time when the auto stop is executed as a result of counting has elapsed has elapsed. In this case, the power supply cut-off signal (Power cut signal) is output to the power supply blocking means 160 (relay) to prevent the battery 170 from being discharged by cutting off the power supply to a specific part.

Along with the power cutoff through the power supply blocking means 160, the battery 170 discharge related information may be displayed to be recognized by a user through a predetermined expression means. As described above, as described above, the instrument panel 90 having a specific symbol lamp for visually expressing the discharge information of the battery 170 and the buzzer 95 for outputting information about the discharge of the battery 170 in the form of a predetermined warning sound, etc. It may include.

On the other hand, when it is determined that the starting is turned off from the battery charging signal (ground (GND, battery charging signal Off) or low level (DC + 3V or less) charging signal input), the automatic stop signal (Auto) performed by the controller 120 The auto stop signal is turned off by the control for stopping the output of the stop signal.

At the time when the predetermined time T2 has not elapsed after the engine auto stop is executed or in the state in which the power supply cut-off means 160 is activated (Power cut signal output state), there is no operation of the main gear pedal 87 (pedal) When the main gear lever 82 is moved out of a specific position and the stop signal output means 100 is switched to Off, the predetermined control for automatic engine start is executed.

Specifically, when the pedal operation detecting means 110 and the stop signal output means 100 are both in the off state after the engine auto stop is executed, the control unit 120 determines that the auto start condition is satisfied and automatically Output a start signal (Auto Start Signal), and transmits the output signal to the fuel supply device 130 and the starter motor (140, starter motor), whereby the spool in the fuel supply device 130 to allow fuel supply It is returned to the side and the starter motor 140 is driven so that the start is turned on again.

When the ignition is turned on again, since the charging current is supplied to the battery 170 by the alternator driving, a charging signal of a predetermined value or more is generated. The auto start signal, which has been output for restarting, is turned off, and the supply of the power cutoff signal is stopped so that power can be supplied to the electric appliance 180 which consumes current.
