And, be to dispose torsionspring on fulcrum b at the lateral operation center of main shift 5370, so that the mode that main shift lever 53 rotates around fulcrum b is to main shift lever 53 application of forces always. Therefore,If main shift lever 53 is operated to neutral position N, main shift lever 53 is applied in from retreating side neutral positionPut Nr march forward side neutral position Nf side active force and move.
As shown in Figure 8, the lateral outer side of the advance side neutral position Nf of described guiding groove 66 is set toEngine stop is engine stop position ES with predetermined operation position, and, configuration on guide plate 65There is the guide rod 53a that detects main shift 53 to be operated to stopping of this engine stop position ESPosition detecting switch S2.
And, dispose at main shift 53 and be operated under the state of engine stop position ESMake these main shift 53 positions keep position holding mechanism A freely.
This position holding mechanism A is made up of elasticity push type haulage gear, and main shift 53 is existedConventionally the operation between operating area Z and engine stop position ES applies moving resistance.
Below, the position holding mechanism A being made up of this haulage gear is described.
As shown in Fig. 8 and Fig. 9, position holding mechanism A is configured on guide plate 65, when main gear changeBar 53 being by when advancing variable speed operation path F or retreat variable speed operation path R and be operated to neutral position N,The active force that overcomes torsionspring 70 pins down main shift 53 moving to engine stop position ESMoving, and, allow by manual operation main shift 53 be operated to engine stop position ES,And be operated to after the ES of engine stop position, pin down the main shift 53 side neutral position of marching forwardThe movement (making main shift 53 be held in engine stop position ES) of Nf.
Specifically, around on lower shaft core swing the one end of swing arm 71 that is supported in freely guide plate 65Portion is provided with roller 72, and the other end is provided with and passes through region (advance side with what roller 72 is pressed into guiding groove 66Courses of action between neutral position Nf and engine stop position ES) mode swing the spiral of the application of forceSpring 73, swing arm 71 overcome helical spring 73 active force and with the fixed part that is formed at guide plate 6574 butts, thus be limited at assigned position.
, main shift 53 by roller 72 fixing and can overcome torsionspring 70 active force andHolding position, and swing arm 71 is stopped at can be by the main shift 53 of manual operationAvoid the position of roller 72.
The main shift 53 that thus, can make to be operated to neutral position N is held in advance sideVertical position Nf, pins down its movement to engine stop position ES, allows by manual operation and will leadShift 53 is operated to engine stop position ES, is being operated to engine stop position ESAfter, pin down the main shift 53 side neutral position Nf that marches forward and move and (make main shift 53Be held in engine stop position ES). In addition, the in the situation that of the main shift of manual operation 53,Allow main shift 53 is operated to advance side neutral position Nf from engine stop position ES.
If main shift 53 is operated to engine stop position ES, stop position detects and opensThe operating portion that closes S2 is operated and stop position sense switch S2 is connected, if by main shift53 are operated to advance side neutral position Nf, and stop position sense switch S2 closes.
Below, the link with brake actuation 52 to main shift 53 with reference to Figure 10～Figure 12Structure describes.
Be operated to advance transport condition or the quilt of the variable speed operation path F that advances at main shift 53Be operated to and retreat the retreating under transport condition of variable speed operation path R, stop by system if step on operation bodyMoving device operating means 52, main shift 53 links with brake actuation 52 interlocks, therebyMain shift 53 forced resettings are operated to neutral position N.
Specifically, as shown in figure 10, disposing at the rear of speed change gear operating portion can be around fulcrum eSwing pin down action component 81. Pin down at this that on action component 81, dispose can be by regulating spiral shellWhat bolt 81b carried out fine position around fulcrum f pins down parts 81a, the leading section that pins down action component 81 fromRear is relative with the first butt pin 82 of fulcrum c top position that is arranged on described transfer rotatable parts 60,Pin down the leading section of parts 81a from rear and the fulcrum c below that is arranged on described transfer rotatable parts 60The second butt pin 83 of position is relative.
On the other hand, in the other end of the pedal bolster 84 being connected with brake actuation 52Be installed with and pin down motion arm 85, that rearward extends from the described lower end that pins down action component 81 pushes awayThe rearward end of bar 87 runs through to be linked to rotates freely pivotal support to pin down motion arm 85 free-ended in thisWheelboss part 86. Wherein, push rod 87 only runs through sliding freely before and after within the specific limits and is supported in wheelBoss assembly 86, and, the compression spiral shell on push rod 87 be arranged on by embedding outside initial compression shifting ground in advanceRevolve spring 88 to push rod 87 application of forces, make it with respect to forwards slide boundary slip of wheelboss part 86.
Before Figure 10 shows and does not step on operational brake operating means 52 and main shift 53 and be positioned atEnter side maximum speed and keep off the state of the 5 gear F5 that advance, Figure 11 shows and does not step on operational brake operationDevice 52 and main shift 53 are positioned at the state that retreats side maximum speed gear and retreat 3 gear R3.
Be positioned under the state of the variable speed operation path F that advances (for example, Figure 10 at main shift 53State), if step on operational brake operating means 52, pin down motion arm 85 along in figure counterclockwiseDirection is rotated, thereby make push rod 87, towards front, (on the left of in figure) gives prominence to, and pins down action component 81 around propping upPoint e swings along clockwise direction. Thus, as shown in figure 12, pin down action component 81 towards front buttPush the first butt pin 82, transfer rotatable parts 60 are forced to rotate around fulcrum c in the counterclockwise direction, mainShift 53 returns to neutral position N side.
Main shift 53 arrives after the N of neutral position, the second butt pin 83 also with pin down parts 81aButt, because the first butt pin 82 and the second butt pin 83 that are positioned at the upper and lower both sides of fulcrum c are all connected toPin down action component 81, therefore transfer rotatable parts 60 keep main shift 53 to be positioned at neutral positionThe fixed pose of N. And, be connected to the operating member that pins down of the first butt pin 82 and the second butt pin 83Part 81 can not further clockwise rotate self. In addition, pin down leading of action component 81 by adjustingThe position of member made 81a, can make the first butt pin 82 and the second butt pin 83 all be connected to pin down movingMake parts 81 and make transfer rotatable parts 60 recover exactly neutral.
Wherein, the initial compression force that compression helical spring 88 applies is set to be greater than and makes main transformer speed behaviourVertical pole 53 is forced mobile necessary operating physical force, before main shift 53 arrives neutral position N,Compression helical spring 88 can be because of the compressed distortion of operation reaction force. And at main shift 53Arrive after the N of neutral position, if further step on operational brake operating means 52, with respect to notPush rod 87 that can be forwards mobile, pins down motion arm 85 and makes the further compression of compression helical spring 88And along counterclockwise rotating in figure, thereby guarantee the stroke of sufficient brake service.
And, be positioned at state (for example, the figure that retreats variable speed operation path R at main shift 5311 state) under, if step on operational brake operating means 52, pin down motion arm 85 along in figureCounterclockwise rotate, thus make push rod 87 forwards (left side in figure) outstanding, pin down action component81 swing along clockwise direction around fulcrum e. What thus, pin down action component 81 pins down parts 81a courtFront butt pushes the second butt pin 83, and transfer rotatable parts 60 are forced along clockwise direction around fulcrum cRotate, main shift 53 returns to neutral position N side.

As shown in figure 13, stop position sense switch S2, secondary speed change sensor S3, lateral tilting oblique angle passThe detected value of sensor S6 inputs to control device H, in addition, and from detecting front-wheel 1 with steering wheel 14The rotary angle transmitter S1 of the corner operating and produce, the engine speed sensing of detection engine 12 rotating speedsDevice S7, the cooling-water temperature sensor S8 that detects the cooling water temperature of engine 12, detection are configured in and driveSail brake sensor S9, the detection of stepping on operation of the brake actuation 52 on portion's platform 16The trailing wheel turn-sensitive device S10 of the axletree rotating speed of left and right sides trailing wheel 2, detect the body 3 that travels and waterTilt fore and aft that flat attitude becomes tilt forward and back angle transducer S11, detect travel body towards orientationSensor S12, detect driver whether ride on driver's seat 15 take switch S 13, detect send outThe information that the hood whether motivation cover 13 opens wide opens and closes sensor S14 also inputs to control device H.In addition, in addition also dispose the voltage detection mechanism (not shown) of the voltage that detects battery V.
Figure 14 shows the power supply supply condition to control device H and other electronic equipments, as this figure instituteShow, if be operated to power position (ON) by key operated key switch 90, electricityThe power supply of pond V is transported to control device H and makes its startup.
And even if key switch 90 is operated to power supply open position (OFF), power supply is supplied with also notCan stop, it is lasting that holding circuit 91 is supplied with power supply at once, is operated to power supply disconnected at key switch 90The operating state of each several part when open position (OFF) is recorded in not shown nonvolatile memoryAfter, holding circuit 91 cuts off, and power supply is supplied with and is stopped. And key switch 90 is operated to start bitWhile putting (ST), the starter being arranged in the power supply supply lines between battery V and starter 93 risesEmploy relay 92 and switch to on-state, thereby starter 93 is moved, and then make engine 12Start.
And, at the main electricity from battery V to all electronic equipment power supplies including control device HIn source circuit 95, be provided with and make the interrupted interrupted ciruit 96 freely of supply of electric power, this interrupted ciruit 96Can switch electric power supply condition and dissengaged positions by carrying out the instruction of self-control device H, and, alsoCan be by the drive circuit 97 of be operated to enable position (ST) when key switch 90 time energising actionSwitch electric power supply condition and dissengaged positions.
And, even in the situation that key switch 90 remains on power position (ON), controlDevice H also can implement in the time that engine stop condition is set up to make that the action of engine 12 stops startingMachine stops controlling automatically, disposes forwardly for switching and implement this engine automatic stop on panel 35Control state with do not implement this control state automatic shutter switch SW, at engine stop barThe display lamp L extinguishing while lighting discontented foot when part meets.
Carry out rice transplanting operation in field time, the rice shoot consuming in for example to rice transplanting operation carries out supply workDuring industry etc., carry out other operations under the state that makes engine stop time, by engine 12 is stoppedOnly can suppress the unnecessary consumption of fuel and reduce noise.
By stop position sense switch S2 exceed schedule time (for example several seconds) carried out making operation workFor described engine stop condition. And, if pin down condition establishment, even if control device H is sending outIn the situation that motivation stop condition is set up, do not implement engine automatic stop control yet.
In addition, although not shown, as for structure that engine 12 is stopped, as long as to rightThe guiding mechanism that adjustment is supplied to the fuel feed of engine 12 carries out electronically controlled engine controlPortion sends engine halt signal (signal of specifically, supplying with for fuel shutoff) and disposes and makesThe structure of the spark plug that engine 12 is lighted a fire, can be by dump of spark plug etc.
Below, the engine automatic stop control of control device H is described.
In addition, in the following description, suppose that automatic shutter switch SW is operated to on-state.
As shown in Figure 16～Figure 18, main shift 53 is operated to engine stop position ES, stopsOnly position detecting switch S2 transfers on-state to, if more than this state maintenance stipulated time, startedMachine stop condition is set up (step 1,2).
But, even engine stop condition establishment, if but the detection of cooling-water temperature sensor S8Value detects battery lower than the condition (step 3) of design temperature, detection information based on voltage detection mechanismThe voltage of V is lower than the condition (step 4) of setting voltage, based on engine speed detecting sensor S7'sDetection information detect engine speed higher than setting value for the condition (step 5) of idling conditions,Detection information based on hull sensor S4 or link angle transducer S5 detects ground connection hull 23 and is positioned atThe condition (step 6) of field ground G top, based on tilting forward and back angle transducer S11 and lateral tilting oblique angleThe detection information of sensor S6 detects travels body 3 or seedling-transplanting device 4 on front and back or left and right directionsBe receipts with respect to condition (step 7) more than horizontal attitude inclination set angle, left and right marking device 29Rise state condition (step 8), detect secondary shift 54 not by secondary speed change sensor S3At least one condition in the condition (step 9) of " planting location " that is operated to is set up, and does not make to startMachine 12 stops.
Condition in step 9 is not grasped for detecting secondary shift 54 by secondary speed change sensor S3Doing to the condition of " planting location ", in other words, is that secondary shift 54 is operated to that " road is upSail position " condition. Like this, in the time that secondary shift 54 is operated to " traveling-position on road ",Do not make engine 12 stop. That is, if engine 12 is stopped on ramp etc. during on the way travelling,Body is run counter to operator's wish and for mobile etc. unfavorable on ramp, can be prevented by this conditionThe generation of this rough sledding.
And, even if the arbitrary condition in above-mentioned steps 3～9 is all in invalid situation, if implementedTurning driving judgement is processed and is judged to be the condition establishment during turning driving, does not also make engine12 stop (step 10,11).
Below, to turning driving, judgement is processed and is described, as shown in figure 19, and in arbitrary trailing wheel rotationThe detected value of sensor S10 is all non-vanishing, is judged as (the step under the state of body 3 during travelling of travellingRapid 101), if the condition of the difference of the detected value of the trailing wheel turn-sensitive device 10 of left and right more than setting valueCondition (the step of the corner of the front-wheel 1 that (step 102), rotary angle transmitter S1 detect more than setting valueRapid 103), the marking device moving in left and right marking device 29 carries out the condition (step of handover operation104), left and right either side clutch 50 be cut off the condition (step 105) of operation, by orientation sensingDevice S12 detect the body 3 that travels towards more cataclysmal condition (step 106), ground connection ship occursCondition (step 107), plantation clutch 40 that body 23 does not contact with field ground G are operated to clutchArbitrary condition in the condition (step 108) of device dissengaged positions is set up, and is judged as in turning drivingDuring this time, arbitrary condition is all false, and is judged as and does not carry out turning driving (step 109,110).
And, after engine 12 starts, even examine at the detected value based on rear wheel sensor S10Measure the body 3 that travels and do not travel mobile or do not send pseudoinstruction the condition that body travels mobile is set up,Can not make engine 12 stop (step 12) yet.
And, if step 1,2 engine stop condition set up, the arbitrary condition in step 3～12All be false, the displaying contents of information display section 36 changes to for showing that implementing engine stops automaticallyThe content (step 13) of only controlling, and, seedling-transplanting device 4 is risen to as desired location one exampleMaximum lifting position after (step 14,15), implement engine 12 is stopped engine automatic stopProcess (step 16). In addition, although not shown, if step 1,2 engine stop condition becomeVertical, the arbitrary condition in step 3～12 is all false, in the operation of applying fertilizer by fertilizer apparatus 7Time, make immediately electric blowing machine 28 stop.
In the time implementing engine automatic stop processing, control device H is in advance by the rice transplanting operation of carrying out beforeThe operating state of each portion be recorded in memory, while again carrying out operation engine 12 is started,Under the state identical with the operating state of storage, carry out operation. For example, the operating state of marking device 52Or the operating state of plantation clutch 40 etc. etc.

Implemented transmitter automatically stop process after, if the detection based on trailing wheel turn-sensitive device S10Value detects trailing wheel 2 for rotation status, the ring by such as siren moving wait give the alarm (step 17,18), implemented engine stop process after through the stipulated time, when aftermentioned engine start condition notWhen establishment, cut off the electricity supply and supply with to prevent battery V electric discharge (step 19,20).
Specifically, send and switch to power cut status command to interrupted ciruit 96, make interrupted ciruit96 cut off, thereby cut off the electric power supply of all electronic equipments.
Switching to as mentioned above after power cut state, for engine 12 is started, operator canKey switch 90 is operated to enable position (ST). , key switch 90 is being operated to start bitPut after (ST), drive circuit 97 moves, and makes interrupted ciruit 96 switch to electric power supply condition, therebyTo control device H and the power supply of other electronic equipments, engine 12 is started.
In the situation that engine 12 being stopped by engine automatic stop processing, if operator willMain shift 53 moves to advance side neutral position Nf and stop position sense switch S2 is switchedTo closed condition, and operator steps on brake actuation 52 and brake sensor S9 is cutChange to on-state (step 21,22), be judged to be engine start condition and set up.
In addition, if from key switch 90, extract key K condition (step 23), be arranged on and driveSail taking condition (step 24) that switch S 13 closes, open and close inspection based on hood on seat 15The detection information of surveying sensor S14 detects in the unlimited condition (step 25) of hood 13 at leastA condition is set up, and does not make engine 12 start.
And, in the time that arbitrary condition of the establishment of engine start condition and step 23～25 is all false, letterThe displaying contents of breath display part 36 changes to for showing that implementing engine starts the content of processing automatically,And, implement to make the engine that engine 12 starts automatically start processing (step 26,27). In addition,Although not shown, if engine start is in the time applying fertilizer operation by fertilizer apparatus 7, verticalEven if electric blowing machine 28 switches to operating state.
As the displaying contents of information display section 36 now, for example, as shown in Figure 15 (d), utilizeNumerical value display part 37 shows " N-ST ".
