Here, it is plane that push-off pin 281, which is configured to top, thus, it is possible to prevent extracting jaw 261L, 261R at a pair The leaf of upper winding seedling 22.

In structure more than, the then action to withdrawing device 200 is illustrated.

As described above, in the withdrawing device fixed component 201 fixed on the body of seeding transplant machine 1 of guide portion 240 firmly Ground fixation is without movement.

With the rotation of actuating arm 220, armite 230 is swung, but the action is formed by insertion in guide portion 240 Guiding groove 241 and with substrate 250 link the first guided member 245 limit.

On the other hand, with the action of armite 230, substrate 250 is also swung, but substrate 250 is directed except first Outside part 245,247 insertion guiding groove of the second guided member 241 (still, the second guided member 247 and armite 230 Do not link), therefore the action repeats moving back and forth along guiding groove 241.Installed on substrate 250 and take out part 260, therefore Part 260 is taken out also to carry out acting with the identical of substrate 250, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, describes the track K of diagram.

Turned position P1~P6 of the actuating arm 220 of diagram and a pair extracting jaw 261L, 261R leading section 261Lp, Position K1~K6 correspondences on 261Rp track K.Also, the arrow recorded on the dotted line for representing track K represents direction of action.

As illustrated, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, from position K1 towards position K2 Action, with from nursery hole 21 choose seedling 22 action it is corresponding.Track K from position K1 to position K2 be it is linear, therefore A pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, are retreated as the crow flies from nursery hole 21.Now, at a pair On extracting jaw 261L, 261R leading section 261Lp, 261Rp, due to the recuperability of extension spring 263, side closer to each other is acted on To power, the seedling 22 chosen from nursery hole 21 can be kept.Also, the front end of extracting jaw 261L, 261R on a pair Portion 261Lp, 261Rp on-off action, the action with push-off pin 281 are ordinatedly further described below.

Also, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, from position K6 moving towards position K1 Make, with the seedling 22 in the nursery hole 21 relative to the pallet 20 in seedling extracting position, make a pair extracting jaw 261L, 261R The action correspondence of insertion, with from position K1 towards path essentially identical position K2 track K on inversely move, therefore one To extracting jaw 261L, 261R leading section 261Lp, 261Rp, substantially straight inserted to nursery hole 21.Now, at a pair Extracting jaw 261L, 261R leading section 261Lp, 261Rp on, overcome the recuperability of extension spring 263, effect is away from each other The power in direction, in the state of the leading section of both sides is opened, can enter nursery hole 21.

Thus, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, will not damage pallet 20, nursery hole 21 and seedling itself.

Also, the track K from position K1 to position K2 and the generally linear shapes of track K from position K6 to position K1, It is due to that the side of the close tray supply apparatus 100 of guiding groove 241 is formed as linear.

Then, with from position K2 towards position K3, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, Before this from the posture relative to nursery hole 21 to attitudes vibration is sharp made approximately below, when being moved to position K4, Leading section 261Lp, 261Rp are generally toward under just.

Also, it is due to that being supplied apart from pallet for guiding groove 241 fills so towards attitudes vibration is sharp made approximately below 100 side farther out is put, the shape that R shapes are erected is shaped generally as.

Also, just at this moment, in leading section 261Lp, 261Rp lower section, towards top dead center in upper on the T1 of track The seedling input port (omitting diagram) for rising the cultivation device 7 of process upward, from position K4 to position K5, passes through release The seedling 22 that bar 281 is released from a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, puts into the seedling of cultivation device 7 Mouth is fallen, and is supplied to planting tool 11.Also, to the action of push-off pin 281, further it is described below.

Then, with from position K5 towards position K6, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, The posture for being approximately towards lower section before this is set sharp to become posture in mode that can be relative with next nursery hole 21 Change, when being moved to position K1, leading section 261Lp, 261Rp are inserted into new nursery hole 21.

By the turned position of actuating arm 220 and a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp rail The corresponding relation of the outline of position on mark K is understood, from position K4 towards position K5 action, and from above-mentioned position K1 directions Position K2 action is compared to can relatively slowly carry out, therefore, it is possible to carry out the taking-up from the seedling 22 in nursery hole 21 as soon as possible, And seedling 22 can be reliably carried out to the releasing of cultivation device 7.

Carry out it is such act, being due to armite 230, (tray supply apparatus 100 is chosen in the front of actuating arm 220 Position) side setting.Also, actuating arm 220 is compared with armite 230, position is chosen farther out apart from tray supply apparatus 100, Therefore it will not be contacted when taking out seedling 22 with seedling 22, not result in obstruction.

Then, illustrated centered on the action of transmission mechanism 290 and ejecting mechanism 280.

As illustrated, by actuating arm 220 to the rotation in B directions, the fixed in the front end sidepiece 220a of actuating arm 220 One gear 291, is revolved round the sun centered on the rotating fulcrum 220b of actuating arm 220 to B directions.First gear 291 is relative to armite 230 rotatably install via the first rotary shaft 291a, the 3rd gear 293 is rotated to B directions via second gear 292. 3rd gear 293 with and the leading section 245b of the first guided member 245 of the one of camshaft 271 fix, and first is drawn Edge 245a near the front end of part 245 is led, is rotationally linked on the other end 230b of armite 230, therefore pass through The rotation of 3rd gear 293, via camshaft 271, cam 270 is rotated to B directions.That is, the drive cycle with actuating arm 220 is matched somebody with somebody Ground is closed, cam 270 is rotated.

Cam 270 is with the peripheral part 272 of thickness change because of place and because of place in the axle of camshaft 271 The outermost edge 273 of distance (external diameter) change of the heart, as illustrated, in outermost edge 273, protuberance 273b and other parts 273a is larger compared to external diameter, in the peripheral part 272 apart from the axle center same distance of camshaft 271, the first scope 272a thickness unfertile land compared with the thickness that remaining thick wall part is the second scope 272b is set.

Based on above structure, when the drive cycle of cam 270 and actuating arm 220 is synchronously rotated, carry out a pair and take Go out pawl 261L, 261R leading section 261Lp, 261Rp from position K6 towards a pair of extracting jaw 261L during position K1 action, The action of 261R leading section 261Lp, 261Rp on-off action and push-off pin 281 is as follows.

That is, cam 270 peripheral part 272 in, thick wall part be the second scope 272b, the pawl front end with pair of right and left is wide The front end face contact of degree limitation projection 262L, 262R, so that a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, Overcome the recuperability of extension spring 263, the power in the direction of effect away from each other is the state that the leading section of both sides is opened.

On the other hand, now, in the outermost edge 273 of cam 270, protuberance 273b keeps being dashed forward with first with extension spring The periphery portion contacts of 283c root bottom part are played, so that pushing arm extension spring 284 is drawn into extension, pushing arm 283 is in figure (reference arrow C) is rotated counterclockwise, the state for maintaining the push-off pin 281 linked with connecting rod 282 to retreat.

Therefore, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, can enter nursery hole 21, by seedling Take out.

Then, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp are carried out from position K1 towards position K2's Leading section 261Lp, 261Rp of a pair extracting jaw 261L, 261R during action on-off action and moving for push-off pin 281 Make as follows.

That is, starting from position K1 towards while position K2 action, in the peripheral part 272 of cam 270, thinner wall section I.e. the first scope 272a is divided to be contacted with the front end face that the pawl nose width of pair of right and left limits projection 262L, 262R, so that a pair Extracting jaw 261L, 261R leading section 261Lp, 261Rp, by the recuperability of extension spring 263, close direction to each other It is mobile, therefore the state that the leading section as both sides is closed.

On the other hand, now, in the outermost edge 273 of cam 270, protuberance 273b still keeps using with extension spring The periphery portion contacts of first projection 283c root bottom part, so that pushing arm extension spring 284 is drawn into extension, pushing arm 283 The state (reference arrow C) rotated counterclockwise is kept in figure, is maintained after the push-off pin 281 with the link of connecting rod 282 The state moved back.Therefore, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp, can be by the seedling 22 of taking-up in front end Firmly held in portion, and keep the state gradually to be moved to the side of cultivation device 7.

Then, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp are carried out from position K4 towards position K5's Leading section 261Lp, 261Rp of a pair extracting jaw 261L, 261R during action on-off action and moving for push-off pin 281 Make as follows.

That is, starting from position K4 towards while position K5 action, in the outermost edge 273 of cam 270, substitution Protuberance 273b other parts 273a, the periphery portion contacts of the root bottom part with the first projection 283c are kept with extension spring, So as to which by the recuperability of pushing arm extension spring 284, pushing arm 283 instantaneously turns into what is rotated clockwise in figure State (reference arrow D), while push-off pin 281 that pushing is linked with connecting rod 282, the leading section 281a of push-off pin 281 Notch 281b, extrude extension a pair extracting jaw 261L, 261R leading section while moving.

Thus, by the leading section 281a of push-off pin 281 from a pair extracting jaw 261L, 261R leading section 261Lp, The seedling 22 that 261Rp is released, falls to the seedling input port of cultivation device 7, is supplied to planting tool 11.Now, before push-off pin 281 End 281a notch 281b, extrudes extracting jaw 261L, 261R for extending a pair leading section while moving, therefore energy It is enough to remove soil for adhering on the leading section etc. simultaneously.

Then, a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp are carried out from position K5 towards position K6's Leading section 261Lp, 261Rp of a pair extracting jaw 261L, 261R during action on-off action and moving for push-off pin 281 Make as follows.

That is, in the peripheral part 272 of cam 270, substitution thin-walled portion is the first scope 272a, and thick wall part is the second model 272b is enclosed, the front end face for limiting projection 262L, 262R with the pawl nose width of pair of right and left is contacted, so that a pair of extracting jaw 261L, 261R leading section 261Lp, 261Rp, overcome the recuperability of extension spring 263, act on the power in direction away from each other, The state change opened to the leading section of both sides.

When on the other hand, near the K6 of in-position, in the outermost edge 273 of cam 270, replace other parts 273a, Protuberance 273b keeps the periphery portion contacts of the root bottom part with the first projection 283c with extension spring, so that pushing arm be stretched The traction extension of spring 284, pushing arm 283 rotates (reference arrow C) counterclockwise in figure, linked to connecting rod 282 Push-off pin 281 retreat state change.

And, although in the above-described embodiment, it is across leading section to making a pair extracting jaw 261L, 261R from root bottom part Integrally it is illustrated with the situation of same metal board member structure, but not limited to this, can also for front By that can unload and flexible such as rubber slab or resin plate are constituted.Thus, extension spring 263 is passed through even in leading section Recuperability clamp seedling 22, also due to the elasticity of front deforms rubber slab, so that the effect of seedling 22 will not be damaged by pressure by playing.

And it is configured to, push-off pin 281 is moved in a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp Before near the K6 of position, extracting jaw 261L, the 261R that a pair of covering leading section 261Lp, 261Rp top, thereby, it is possible to anti- Only when being moved from position K5 to position K6, the leaf of the seedling 22 on pallet 20 is in a pair extracting jaw 261L, 261R front end Hooked on portion 261Lp, 261Rp.

Also, push-off pin 281 is configured to coordinate a pair extracting jaw 261L, 261R leading section 261Lp, 261Rp insertion Retreat, thereby, it is possible to prevent the leaf of seedling 22 from being twined on leading section 261Lp, 261Rp insertion speed during nursery hole 21 Around.

Then, again so as to enter centered on the mechanism that the pallet means of delivery 121 of tray supply apparatus 100 intermittently drives One step is illustrated.

Pallet longitudinal conveying device 120, possesses：(1) above-mentioned pallet means of delivery 121；(2) fixed tray means of delivery 121 both ends 121b upper front end portion 121b1, folk prescription has the bending edge 131a of inside lateral bend overshooting shape cam The 131 means of delivery arms 130 formed in bottom；(3) root bottom part 141 rotates freely twelve Earthly Branches on the side plate 110a of seedling carrying base 110 Support, with the front end axle portion 142 of leading section by means of delivery arm 130 rotatably support on lower end edge portion by the first recess The conveying arm 140 that 143a, the second convex portion 143b, the 3rd recess 143c are smoothly continuously formed in side view；(4) from taking-up dress Put 200 sides and see the longitudinally fed drive shaft rotated by the driving force obtained from the power source of seeding transplant machine 1 to arrow E directions 151, fix, rotated on leading section respectively on the middle position of longitudinally fed drive shaft 151 and 2 positions of right end position There is the longitudinally fed actuating arm 150 for pining down roller 152 freely.Therefore, front end axle portion 142 is to link pallet means of delivery 121 Rotating fulcrum axle.

Also, the front end axle portion 142 in the leading section of conveying arm 140, the bottom with the side plate 110a of seedling carrying base 110 Between 110a1, in the way of applying the power stretched downwards all the time to conveying arm 140, conveying arm extension spring 160 is installed.Should Conveying arm extension spring 160 is that the conveying that conveying arm 140 exerts a force to the conveying direction of action of pallet means of delivery 121 is applied Power has.Also, on the root bottom part 141 of conveying arm 140, it is fixed with and is maintained at what is installed on the upper end of means of delivery arm 130 The turnover pressing plate 163 of another square end of the means of delivery arm extension spring 161 of one square end is installed on pin 132.The means of delivery Arm extension spring 161 be to pallet means of delivery 121 to centered on the front end axle portion 142 as rotating fulcrum axle enter nursery The force entered the tool of the side force of gap 21b between hole 21.

Then, the action to the interval of pallet means of delivery 121 is illustrated.

By the rotation of Endrem axle 171, the right direction of seedling carrying base 110 is the movement of arrow F directions.Now, longitudinal direction is defeated Drive shaft 151 is sent to be rotated to arrow E directions.

Therebetween, withdrawing device 200 sequentially takes out seedling 22 from the nursery hole 21 of right-hand member and supplies seedling 22 to cultivation device 7, its The time point moved afterwards in seedling carrying base 110 to low order end, the seedling 22 in the nursery hole 21 of high order end is removed device 200 and taken out.By This, whole seedlings 22 of the horizontal row amount in nursery hole 21 are taken out.

Now it is configured to, to the rotation of arrow E directions in longitudinally fed drive shaft together with longitudinally fed drive shaft 151 That is rotatably installed on the leading section for the longitudinally fed actuating arm 150 that 151 right-hand member is fixed pins down roller 152, start with After first recess 143a of conveying arm 140 contact, slightly start the contact with the bending edge 131a of means of delivery arm 130 late, Therefore pallet means of delivery 121 rises after movement temporarily along with the clockwise rotation of conveying arm 140, with the front end of leading section Start to rotate counterclockwise centered on axle portion 142.

That is, the direction of from pallet means of delivery 121 to arrow 121a0 rise movement temporarily, are cut so as to be held in before this The jut 121ab of oral area 112a pallet means of delivery 121 deviates from from notch 112a, and before this in nursery hole The central portion 121a of pallet means of delivery 121 standby the gap 21a of 21 dorsal part, also to arrow in the range of the 21a of the gap Head 121a0 direction rises movement.Hereafter, means of delivery arm 130 is started counterclockwise centered on the front end axle portion 142 of leading section Rotate, so that the central portion 121a of pallet means of delivery 121 is moved to arrow 121a1 direction.Also, notch 112a's cuts Mouth depth, is set as the degree that the central portion 121a of pallet means of delivery 121 can be moved in the range of the 21a of gap.

Hereafter, roller 152 is pind down further persistently to rotate, then pin down roller 152 continue and means of delivery arm 130 bending edge 131a contact, therefore the central portion 121a maintenances of pallet means of delivery 121 are located at the state for keeping out of the way groove 111a.Now, simultaneously Ground pins down roller 152 and moved from the first recess 143a of conveying arm 140 to the second convex portion 143b, therefore conveying arm 140 is further suitable Hour hands are rotated, the central portion 121a of pallet means of delivery 121, and result is to maintain to be located at the state for keeping out of the way groove 111a, to arrow 121a2 direction movement.

Hereafter, pin down roller 152 further persistently to rotate, then pin down the bending edge of roller 152 and means of delivery arm 130 While 131a is contactless state, by the recuperability of means of delivery arm extension spring 161, means of delivery arm 130 is with front end Instantaneously rotated clockwise centered on the front end axle portion 142 in portion so that the central portion 121a of pallet means of delivery 121, to from Gap 21a is located at the gap 21b of upside with a row amount in nursery hole 21, is moved as shown in arrow 121a3.

Hereafter, pin down roller 152 further persistently to rotate, then pin down the one side of roller 152 and the 3rd recess 143c of conveying arm 140 Contact is while move, therefore by the recuperability of conveying arm extension spring 160, conveying arm 140 is stretched downwards, pallet conveying The central portion 121a of instrument 121, result is to maintain the state positioned at gap 21b, and is moved to arrow 121a4 direction, and And the central portion 121a of pallet means of delivery 121 jut 121ab is kept on notch 112a.

Also, the central portion 121a of the pallet means of delivery 121 moved to arrow 121a4 direction, maintains to be located at nursery The state in the mutual gap in nursery hole of the dorsal part in hole 21, seedling carrying base 110 starts to move to arrow G directions, i.e. left direction, Then withdrawing device 200 sequentially takes out seedling 22 from the nursery hole 21 of left end and supplies seedling 22 to cultivation device 7, hereafter in seedling carrying base 110 time points moved to high order end, the seedling 22 in the nursery hole 21 of low order end is taken out with withdrawing device 200.Thus, by nursery Whole seedlings 22 of the horizontal row amount in hole 21 take out.

Also, therebetween, the central portion 121a of pallet means of delivery 121 jut 121ab is kept on notch 112a, Therefore, it is possible to prevent from making the offset motion downwards of pallet 20 because the weight of the seedling 22 in nursery hole 21 is entered.

Also, when whole seedlings 22 of the horizontal row amount in nursery hole 21 are taken out, then with above-mentioned difference, driven longitudinally fed That is rotatably installed on the leading section for the longitudinally fed actuating arm 150 that the middle position of moving axis 151 is fixed pins down roller 152, Start the bending edge 131a of means of delivery arm 130, the contact with the first recess 143a of conveying arm 140.

By repeating above-mentioned action, the right direction of pallet 20 or left direction movement, and with a row amount in nursery hole 21 Intermittently carry out longitudinally fed.

Thereby, it is possible to obtain compactly designed pallet longitudinal conveying device 120.Further, it is possible to by guide rail 155, The simple construction of Endrem axle 171 movably supports on pallet carrying road 111.

Also, the central portion 121a of pallet means of delivery 121, is configured on the planar portions 111b on pallet carrying road 111, because This pallet 20 will not be bent as inner side, therefore in the dorsal part in nursery hole 21, it can be ensured that gap 21a, 21b of one fixed width, Therefore pallet means of delivery 121 can be reliably into gap 21a, 21b.

Also, pallet carrying road 111 planar portions 111b downstream be provided with curved face part 111c, therefore pallet 20 along The curved surface is bent.Therefore, when pallet is conveyed, direction from pallet means of delivery 121 to arrow 121a2 move when, this is deflected into For resistance, it can prevent that downstream side is offset pallet 20.

Various operation handles then, to handlebar grip 8L, 8R of the pair of right and left in operating handle 8 neighbouring configuration, And operating portion 600 is illustrated.

In the handlebar grip 8L in the left side of operating handle 8 neighbouring setting main clutch handle 80, the handlebar grip on right side Provided with the descending operation handle 81 for acting hydraulic lifting cylinder 10 near 8R.

Descending operation handle 81 is configured to manual switching for " decline ", " neutrality ", 3 stages of " rising ", works as switching For " decline " position when, hydraulic lifting cylinder 10 is stopped by sensor board 710 described later in order that running vehicle body 15 declines and acted Only decline, and if plantation break-make button 620 described later is ON states, then it is " logical " state to plant clutch 420, starts to plant Plant operation.Also, the plantation break-make 620 planting operations instrument to switch between following state of button：I.e. in descending operation During tool operation to the step-down operation position for making the decline of running vehicle body 15, linkedly make what planting tool 11 worked with aforesaid operations State and the state for making the work of above-mentioned planting tool 11 and aforesaid operations not interlock.

Also, when descending operation handle 81 is switched into " neutrality " position, then stop plantation operation, when switching to During " rising " position, then hydraulic lifting cylinder 10 is in order that running vehicle body 15 rises and acted.

Also, on guidance panel 601, it is configured with from its left end towards right-hand member sequentially：(1) running vehicle body 15 is made Traveling stop in the state of only making that planting tool 11 acts empty plant operation button 610；(2) when descending operation handle 81 is to making During the step-down operation position operation that running vehicle body 15 declines, switching to linkedly makes what planting tool 11 was acted with the step-down operation The plantation break-make button 620 of state, any one state of the state not interlocked with the step-down operation；(3) at least show that plantation is planted The display part 630 of spacing in the rows；(4) at least regulation plantation plant away from regulation button 640.

According to said structure, plantation break-make button 620 is configured near the central portion of guidance panel 601, therefore is easy to behaviour Make.

Also, sky plants the 601b behind the upper surface 601a from configuring other operation buttons is different of operation button 610 Left side is configured, therefore, it is possible to reduce the maloperation of operator.

Also, display part 630 is configured near the center of guidance panel 601, therefore is easily confirmed.

Regulation button 640, which possesses in upside to " rising " for the direction change for expanding spacing in the rows, presses the 640a and under of compressing switch Side possesses " decline " to the direction change for reducing spacing in the rows by the 640b that compresses switch.

According to said structure, " rising " is operated by the 640a that compresses switch, " decline " by the 640b that compresses switch, so that by table Show that the numerical value of spacing in the rows is directly shown on display part 630, therefore operator easily recognizes spacing in the rows.

Then, with the behaviour based on planting depth adjustment mechanism 700, plantation break-make button 620, descending operation handle 81 etc. Make, illustrated centered on the control unit 800 of the action of the grade of solenoid 470 for the break-make that control is planted.

Planting depth adjustment mechanism 700, possesses：(1) planting depth of seedling is kept certain by being contacted with farmland face 701 Bottom surface broad warp sensor board 710；(2) as the substantially plate-shaped member of L-shaped shape, the bending section of L words during side view Rotatably supported by rotation support shaft 721 relative to running vehicle body 15, the one end 722 and sensor board rearward extended 710 leading section 711 rotatably links via rotation support shaft 722a, and the other end 723 extended upward, with The depth handle 730 that transmission operator is manually operated the position in vertical (up and down) direction of setting sensor plate 710 is acted Transmission lever 740 the depth arm 720 that rotatably links of leading section 741；(3) depth arm 720 is swung from main frame 17 The spring 750 hung freely；(4) as the substantially plate-shaped member of L-shaped shape in side view, the bending section of L words is by turning Dynamic support shaft 761 is rotatably supported relative to running vehicle body 15, and elongated hole 762 is formed with the bottom of rotation support shaft 761, and And the extension spring 766 by linking with upper end 763, in order to which rotation support shaft 761 is rotated as shaft core to arrow Y-direction And exert a force, the descending operation valve (omitting diagram) possessed relative to hydraulic switching valve portion 40, leading section 764 is linked with bar 765 Reverse arm 760；(5) detect that handle 771 is located at the front mode of the elongated hole 762 of reverse arm 760 with break-make, in reverse arm 760 The plantation switch 770 of upper configuration；(6) in the connecting pin 781a insertion elongated holes 762 set at one end in portion 781, the other end 782 The rodmeter 780 rotatably linked via the upper end 712 of connection shaft 783 and sensor board 710.

And be configured to, rodmeter 780 with to sensor board 710 caused by the swing in the upper direction of sensor board 710 Upper end 712 arrow Z-direction swing interlock so that the nose lip 781b of one end 781 to push break-make detect The direction movement of handle 771, it is ON plantation is switched 770.

According to said structure, depth arm 720 is suspended in midair by spring 750, therefore, it is possible to eliminate depth arm 720 and depth handle Rocking for 730 linking portion, passes through the depth stabilization of the setting of depth handle 730.And, although spring 750 is suspention depth The structure of arm 720, but not limited to this, for example, can also be the structure for pushing depth arm 720 to main frame side.

Also, according to said structure, reverse arm 760 is drawn in the side for pushing sensor board 710 upwardly through extension spring 766 Stretch, therefore, it is possible to eliminate rocking for rodmeter 780 and reverse arm 760.

Also, by changing the elastic force of extension spring 766, the power for pushing sensor board 710 can be changed.

Then, the control unit 800 set in the lower section of guidance panel 601 is said to the control method of solenoid 470 It is bright.

It is configured in control unit 800, at least inputs make-and-break signal, descending operation hand from plantation break-make button 620 The switching signal of handle 81, the make-and-break signal from plantation switch 770, by these input signals, pulse is exported to solenoid 470 Signal.

Based on above structure, illustrated centered on the action of control unit 800.

Here, make assigned position from seeding transplant machine 1 to farmland movement after, be divided into (1) to start plant operation scene；Its (2) in farmland while plant operation while the scene of traveling afterwards；And the scene that the end on (3) to ridge is turned back is illustrated.

(1) scene of plantation operation is started：

When making seeding transplant machine 1 move to the assigned position in farmland, plantation break-make button 620 is set as " leading to " state, Descending operation handle 81 is set as " to rise " position, the overall height of running vehicle body 15 is in higher position.

Then, operator operates descending operation handle 81 to " decline " position, reduces the overall height of running vehicle body 15, so that Sensor board 710 is set to decline together with running vehicle body 15 towards farmland face 701.

When sensor board 710 is contacted with farmland face 701, then the leading section 711 of sensor board 710 turns to arrow Z-direction It is dynamic, therefore the nose lip 781b of rodmeter 780 detects that the direction of handle 771 is moved to pushing break-make, plantation is switched 770 For ON, so as to will be inputted from the ON signals of plantation switch 770 to control unit 800.

Control unit 800 receives to represent the signal of " logical " state under the conditions of AND from plantation break-make button 620, from lifting behaviour Make handle 81 to receive to represent the signal of " decline " position, receive " ON " signal from plantation switch 770, so that exporting makes solenoid 470 signals being powered.

Thus, plantation clutch 420 switches to " logical " state from " disconnected " state, starts to plant operation.

(2) while carrying out plantation operation in farmland while the scene of traveling：

Here, descending operation handle 81 is in " declines " position, sensor board 710 according to the concavo-convex of farmland face 701 on Lower action.

Also, control unit 800 is relative to solenoid 470, in order to be powered with the defined action cycle, by pulse signal with it Action cycle exports.Therefore, plantation clutch 420 is powered by solenoid 470 and turns into " logical " state, and interval cam 441 start to rotate and after carrying out 1 rotation terminating and (after the plantation action for carrying out a seedling terminating) then with the action cycle Repeat a series of action of return " disconnected " state.

Thereby, it is possible to intermittently carry out plantation operation, plantation plant needed for realizing away from.

According to the up and down action of sensor board 710, hydraulic lifting cylinder 10 is acted as follows.

That is, when sensor board 710 is moved upward, then the leading section 711 of sensor board 710 is with rotation support shaft 722a Centered on moved to arrow Z-direction, and when the connecting pin 781a that be set on the one end 781 of rodmeter 780 is to pushing The exterior region of elongated hole 762 direction movement when, then reverse arm 760 with rotation support shaft 761 be shaft core in figure to side clockwise To rotation, descending operation valve (omitting diagram) transmission that the action possesses via bar 765 to hydraulic switching valve portion 40, to hydraulic pressure liter The direction action that cylinder 10 extends, the overall height rise of running vehicle body 15 are dropped.

On the other hand, when sensor board 710 is moved downwards, the leading section 711 of sensor board 710 is with rotation support shaft Moved centered on 722a to the direction opposite with arrow Z-direction, and the company set on the one end 781 of rodmeter 780 Knot pin 781a is moved to the remote direction of the exterior region from elongated hole 762, then being stretched the tensile force of spring 766 makes reverse arm 760 be that shaft core is rotated to arrow Y-direction with rotation support shaft 761, and the action possesses via bar 765 to hydraulic switching valve portion 40 Descending operation valve (omitting diagram) transmission, the direction shortened to hydraulic lifting cylinder 10 is acted, the overall height reduction of running vehicle body 15.

By above-mentioned action, there are bumps on farmland face 701, also the planting depth of seedling can be kept certain.

(3) scene turned back to ridge end：

Under the scene, operator in order to interrupt plantation operation, make descending operation handle 81 from " decline " position to " in It is vertical " position movement.

Thus, control unit 800 receives the signal of expression " neutrality " position from descending operation handle 81, stops to helical The output of the pulse signal of pipe 470.Thus, it is continuous to maintain in plantation clutch 420 after " logical " state switches to " disconnected " state " disconnected " state, so as to interrupt plantation operation.

And then, operator makes descending operation handle 81 from " neutrality " in order that running vehicle body 15 is turned back towards adjacent ridge Moved to " rising " position position.

Linkedly, hydraulic switching valve portion 40 possesses for the action of cable 82 corresponding to operation with the descending operation handle 81 Descending operation valve (omit diagram) action, the direction extended to hydraulic lifting cylinder 10 is moved, so that the overall height of running vehicle body 15 Rise.

Now, sensor board 710 declines, and plantation switch 770 is OFF state, will not export any letter from control unit 800 Number.

Also, plantation clutch 420 maintains state of " breaking ", continue to plant the state of job interruption.

Therefore operator makes running vehicle body 15 turn back.

Then, operator makes descending operation handle 81 from " rising " position process " neutrality " position to " decline " position move It is dynamic, then with the action of the cable 82 corresponding to the operation of descending operation handle 81 linkedly, the liter that hydraulic switching valve portion 40 possesses Drop operation valve events, the direction shortened to hydraulic lifting cylinder 10 is moved, so as to start to make the overall height of running vehicle body 15 to reduce.And And, by the aforesaid operations of descending operation handle 81, signal of the descending operation handle 81 in " decline " position will be represented to control Portion 800 processed is exported.

Also, the car body of running vehicle body 15 is fallen, after sensor board 710 is contacted with farmland face 701 soon, then with above-mentioned Similarly, plantation switch 770 is ON to the situation of explanation, and the signal is inputted into control unit 800 in project (1).

Plantation break-make button 620 remains ' on ' state, therefore control unit 800 connects in AND conditions from plantation break-make button 620 By the signal of " logical " state of expression, receive to represent the signal of " decline " position from descending operation handle 81, connect from plantation switch 770 By " ON " signal, so as to export the signal for making solenoid 470 be powered.That is, control unit 800 as described above, relative to helical Pipe 470, in order to be powered with the defined action cycle, pulse signal is exported with the action cycle.

Thus, plantation clutch 420 switches from " disconnected " state to " logical " state, starts again at plantation operation.

According to said structure, plantation break-make button 620 is placed in " logical " state, only descending operation handle 81 grasped Make, start above-mentioned (1) plantation operation, hereafter (2) are travelled on one side while carrying out plantation operation in farmland, and (3) to After ridge end is turned back, a series of operations such as plantation operation are carried out continuously again.
