A. to solenoid 470 be energized (utilizing the short time of pulse signal to be energized) time, the then movable platen 472 of solenoid 470 front end, the tensile force overcoming extension spring 480 is attracted by the direction to arrow B, one end 460a of the first arm 460 and the other end 462b of the second arm 462, centered by rotating fulcrum 461, (arrow C with reference to Fig. 4) rotates counterclockwise.

Thus, an end 460a of the first arm 460 away from plantation clutch 420, thus carries out following i) and action ii).

I) this plantation clutch 420 becomes " leading to " state, power transmission shaft 421 rotates, thus to the second gear 430 side transmission of drive force, make to move up and down arm driving shaft 440 via the 3rd gear 450 to start to rotate, and ii) the recess 441a that formed from the edge, periphery at interval cam 441 of the other end 462b of the second arm 462 is away from (before this, the other end 462b of the second arm 462 is positioned at the recess 441a of interval cam 441, and plant clutch 420 and be in " breaking " state, move up and down arm driving shaft 440 to stop operating), while along edge, the periphery 441b of convex, interval cam 441 and move up and down arm 320 and continue rotation on one side.

Namely, stop being energized to solenoid 470 and the attraction to arrow B can not being produced, but the other end 462b of the second arm 462, during the state of edge, periphery 441b maintaining the convex along interval cam 441, one end 460a of the first arm 460 is away from plantation clutch 420, and therefore this plantation clutch 420 can maintain " leading to " state.Further, by moving up and down the rotation of arm 320, plantation tool 11 (with reference to Fig. 3) continues to move up and down (plantation action), and during before interval cam 441 completes 1 rotation, plantation tool 11 performs 1 plantation action.

B. thereafter, interval cam 441 carries out 1 rotation, when the other end 462b of the second arm 462 arrives the recess 441a of interval cam 441, by the tensile force of extension spring 480, first arm 460 rotates clockwise, and an end 460a of the first arm 460 abuts with plantation clutch 420, thus carries out following i) and action ii).

I) planting clutch 420 is " breaking " state, the rotation of power transmission shaft 421 stops, thus can not to the second gear 430 side transmission of drive force, therefore move up and down arm driving shaft 440 to stop operating, and ii) the other end 462b of the second arm 462 continues to stop (before this in the recess 441a formed on the edge, periphery of interval cam 441, the other end 462b of the second arm 462 uses edge, the periphery 441b of the convex of cam 441 along interval, and plant clutch 420 and be in " leading to " state, move up and down arm driving shaft 440 to continue to rotate), interval cam 441 and move up and down arm 320 and continue to stop operating, therefore plant tool 11 (with reference to Fig. 3) lasting stopping to move up and down (plantation action).

C. and then thereafter, be energized with chien shih solenoid 470 time arbitrary, then planting clutch 420 is " leading to " state, starts the action illustrated in above-mentioned project A.

According to above-mentioned formation, by controlling the above-mentioned arbitrary time be energized to solenoid 470, the time that plantation the moving up and down of tool 11 (plantation action) stops can being regulated.Thereby, it is possible to realized interval plantation simply to form.

And, the action cycle of the time that solenoid 470 is energized, i.e. solenoid 470, based on plantation spacing in the rows and the travel speed (" plantation 1 (low speed) " described later or " plantation 2 (at a high speed) ") of operator's setting, decided by control part 800.To this, main Figure 12 and Figure 14 of use describes further later.

Then, use Fig. 5, Fig. 6, be described further centered by above-mentioned gear change hand lever 190.

Fig. 5 is the stereogram of gear change hand lever 190, and Fig. 6 is the general profile chart be described the change gear mechanism of gearbox 4.

Gear change hand lever 190 as shown in Figure 5, is the switching for carrying out 3 driving modes that " advance " travels, " neutral (stopping) " and " retrogressing " travels; " plantation 1 " that the travel speed of carrying out when planting operation is set lower; The handle of the switching of " plantation 2 " that travel speed set higher is the formation that operator can rotate in a manual manner.

Further, the leading section of gear change hand lever 190, namely with operator with the gear change hand lever end 191 of the part of holds and handle 192 opposite side, link with one end of the change gear mechanism of gearbox 4.

Change gear mechanism, possesses: the gear 194 that the size slidably kept movably on main shaft 193 is a pair; Main shaft 193 configures abreast slidably, end side 196a is outstanding outside gearbox 4,5 through hole 196b are formed, the bar-shaped speed change shift fork 196 that the gear gearshift plate 195 making the gear 194 of size a pair slide movement is fixed on the way in another side; On the opening portion of through hole 196b by spring 196c push the steel ball 196d that configures, in order on the end side 196a of speed change with shift fork 196, form speed change shift fork 196 and the rotational action of gear change hand lever 190 can to shift gears in axial direction linkedly the formation of movement, link with the leading section 197a of web 197 fixing, outstanding to the direction orthogonal with the turning cylinder of this gear change hand lever end 191 on gear change hand lever end 191.

Further, the foundation portion of web 197 is formed with jut 197b.And, in order to detect the switching using gear change hand lever 190 to the travel speed of carrying out when planting operation, this jut 197b be configured to the turned position of gear change hand lever 190 accordingly, the first varying speed switch 198 configured near this jut 197b and respective switch movable platen 198a, the 199a of the second varying speed switch 199 are pushed or are not pushed.

That is, when gear change hand lever 190 switches to " plantation 1 " carrying out plantation operation with the travel speed of low speed, the first varying speed switch 198 is ON and the second varying speed switch 199 is OFF.

On the other hand, when gear change hand lever 190 switch to carry out plantation operation " plantation 2 " with travel speed at a high speed, the first varying speed switch 198 is OFF and the second varying speed switch 199 is ON.

Further, when gear change hand lever 190 switches to the position of " neutral (stopping) " pattern, the first varying speed switch 198 is OFF and the second varying speed switch 199 is ON.

Further, no matter gear change hand lever 190 is set as arbitrary pattern of " advance " pattern and " retrogressing " pattern, is all that the first varying speed switch 198 is for OFF and the second varying speed switch 199 is OFF.

In either case, owing to being the formation of ON information or OFF information being carried to control part 800 from each switch, therefore control part 800 can judge to set " plantation 1 " by gear change hand lever 190 or set " plantation 2 ", still sets " neutral (stoppings) " pattern (reference Figure 14).

In the present embodiment, owing to being the formation of situation by control part 800 " neutral (the stopping) " pattern that judges that gear change hand lever 190 is set as, thus when running vehicle body 15 stops travelling, electrical instruction is sent to solenoid 470 from control part 800, make plantation clutch 420 for " leading to " state, plantation tool 11 action can be made, under neutral pattern, play the effects such as the transmission confirmation can carrying out planting tool 11.

Further, the effective utilization in the control etc. of plantation spacing in the rows for the above-mentioned result of determination of control part 800 is carried out describing further later.

Further, the position of the gear 194 of the web 197 shown in Fig. 6 and size a pair, about being set as the situation of " advance " driving mode at gear change hand lever 190 and being set as the situation of two sides of situation of " retrogressing " driving mode, describes with solid line respectively.

According to above formation, the situation of the arbitrary pattern 5 of from " advance " to " retrogressing " shown in Fig. 5 is set as according to gear change hand lever 190, speed change shift fork 196 slides movement in axial direction, thus the gear 194 of size a pair slides mobile, change the gear (omitting diagram) becoming object of connection.

And, withdrawing device 200, possess: as the cam 270 with the camshaft 271 of above-mentioned first guided member 245 one that has of rotatably through substrate 250, about the thickness of the peripheral part of this cam 270, limiting projection 262L with the pawl nose width of the pair of right and left that face in extracting jaw 261L, 261R of above-mentioned a pair is arranged, the front end face of 262R is when contacting, and changes the peripheral part 272 of thickness according to the place of its peripheral part; About the distance (also referred to as external diameter) at axle center of the outermost edge distance camshaft 271 of this cam 270, possess the place according to its outermost edge and change the cam 270 of the outermost edge 273 of its external diameter; Substrate 250 rotatably links, by the change of the external diameter of the outermost edge 273 of cam 270, along extracting jaw 261L, 261R of a pair, by taking out from nursery hole 21 with the ejecting mechanism 280 that the seedling 22 that extracting jaw 261L, 261R of a pair keep is released.

Further, with edge 245a near the front end of the first guided member 245 of camshaft 271 one, the other end 230b of armite 230 links rotationally.And, with the first guided member 245 of camshaft 271 one, utilize the revolving force of actuating arm 220, the transmission mechanism 290 formed via the first gear 291, second gear 292, the 3rd gear 293 rotates, and is to coordinate the drive cycle of actuating arm 220 to the formation of camshaft 271 transmission of drive force.

And be configured to, when the peripheral part 272 of cam 270, limit projection 262L with the pawl nose width of the pair of right and left arranged in the inner face side of extracting jaw 261L, 261R of a pair, the front end face of 262R is when contacting, by the interaction of the change of the thickness of the peripheral part 272 of cam 270 and the recuperability of extension spring 263, make extracting jaw 261L, 261R opening and closing of a pair.

Then, above-mentioned transmission mechanism 290 is described further.

That is, the first gear 291 is fixing on the front end sidepiece 220a of actuating arm 220, relative to armite 230, rotatably installs via the first turning cylinder 291a.And, 3rd gear 293 is fixing on the leading section 245b of the first guided member 245 with camshaft 271 one, edge 245a near the front end of the first guided member 245, the other end 230b of armite 230 links rotationally, and therefore the 3rd gear 293 rotatably keeps relative to armite 230.Therefore, the 3rd gear 293 and the first guided member 245 rotate integratedly.Further, the second gear 292 is rotatably installed on the middle position of armite 230, is clipped by the first gear 291 and the 3rd gear 293 liang of sides, chimeric with the gear of both sides.

Then, to above-mentioned ejecting mechanism 280, main reference Figure 10 is described further.

Ejecting mechanism 280, possesses: the leading section 281a released by the seedling 22 kept with extracting jaw 261L, 261R of a pair bending and form the push-off pin 281 with the notch 281b of the width fits of the leading section of extracting jaw 261L, 261R squarely; Be rectangular-shaped connecting rod 282 as roughly bending, the leading section 282a of one side is rotatably inserted in the rear stomidium portion 281c that the rearward end of push-off pin 281 is arranged, the connecting rod 282 kept with the split pin (omitting diagram) of anticreep; The leading section 282b of the opposing party of connecting rod 282 is fixing on the 283a of upper end, bottom 283b is rotatably installed relative to substrate 250 by pushing arm connection shaft 283d, is arranged the pushing arm 283 of the extension spring maintenance first projection 283c of central portion; One end keeps with hook on the first projection 283c, the other end at the pushing arm extension spring 284 of extension spring fixing on substrate 250 maintenance hook on the second projection 250a at extension spring.

And be configured to, when cam 270 rotates to arrow B direction, the protuberance 273b that external diameter is larger compared with other parts 273a in outermost edge 273, the periphery portion contacts of the root bottom part with the first projection 283c is kept with extension spring, thus pushing arm extension spring 284 tractive is extended, pushing arm 283 rotates in Fig. 10 counterclockwise, retreats (reference arrow C) with the push-off pin 281 that connecting rod 282 links.And be configured to, when cam 270 rotates to arrow B direction, at the other parts 273a that in outermost edge 273, external diameter is less compared with protuberance 273b, the periphery portion contacts of the root bottom part with the first projection 283c is kept with extension spring, thus pushing arm extension spring 284 shrinks, pushing arm 283 rotates in Fig. 10 clockwise, and the push-off pin 281 linked with connecting rod 282 is outstanding (reference arrow D) gradually.When push-off pin 281 is given prominence to, the leading section of extracting jaw 261L, 261R of a pair, by the notch 281b arranged on the leading section 281a of push-off pin 281, is therefore configured to remove the soil etc. adhered at its leading section.

Here, it is plane that push-off pin 281 is configured to top, can prevent the leaf being wound around seedling 22 on extracting jaw 261L, 261R of a pair thus.

In above formation, be then described with reference to the action of Fig. 9 ~ Figure 11 to withdrawing device 200.

As mentioned above, the withdrawing device fixed part 201 that guide portion 240 is fixing on the body of seeding transplant machine 1 firmly fixes and does not move.

With the rotation of actuating arm 220, armite 230 swings, but this action is subject to the guiding groove 241 of through formation in guide portion 240 and limits with the first guided member 245 that substrate 250 links.

On the other hand, with the action of armite 230, substrate 250 also swings, but substrate 250 is except the first guided member 245, the through guiding groove of second guided member 247 241 (but, second guided member 247 does not link with armite 230), therefore this action repeats moving back and forth along guiding groove 241.Substrate 250 is installed and takes out parts 260, therefore take out parts 260 and also carry out the action identical with substrate 250, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, describe the track K shown in Figure 10, Figure 11.

Here, Figure 11 is the ideograph of the corresponding relation of the outline of position on the track K of leading section 261Lp, 261Rp of the position of the rotation representing actuating arm 220 and extracting jaw 261L, 261R of a pair.Turned position P1 ~ the P6 of the actuating arm 220 shown in Figure 11 is corresponding with the position K1 ~ K6 on the track K of leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair.Further, represent that the arrow that the dotted line of track K is recorded represents direction of action.

As shown in figure 11, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair are from position K1 towards the action of position K2, corresponding with the action of seedling 22 of choosing from nursery hole 21.Track K from position K1 to position K2 is linearity, and therefore leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, retreats as the crow flies from nursery hole 21.Now, on leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, due to the recuperability of extension spring 263, act on the power in approximating direction, the seedling 22 of choosing from nursery hole 21 can be kept.Further, about the on-off action of leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, with the action of push-off pin 281 ordinatedly, describe later further.

And, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, from position K6 towards the action of position K1, with relative to be in seedling extracting position pallet 20 nursery hole 21 in seedling 22, the action that extracting jaw 261L, 261R of a pair are inserted is corresponding, moving inversely with on the path substantially identical towards the track K of position K2 from position K1, therefore leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, inserts substantially as the crow flies to nursery hole 21.Now, on leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, overcome the recuperability of extension spring 263, the power in effect direction away from each other, under the state of leading section opening both sides, can enter nursery hole 21.

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

Further, the track K from position K1 to position K2 and the track K from position K6 to position K1 is roughly linearity, is because the side of the close tray supply apparatus 100 of guiding groove 241 is formed as linearity.

Then, along with from position K2 towards position K3, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, below roughly, attitudes vibration is made sharp before this from the attitude relative to nursery hole 21, when moving to position K4, leading section 261Lp, 261Rp are substantially towards under just.

Further, below roughly, make attitudes vibration sharp like this, be due to the distance tray supply apparatus 100 of guiding groove 241 side far away, be formed as the shape that roughly R shape erects.

And, just at this moment, in the below of this leading section 261Lp, 261Rp, towards the cultivation device 7 of the rising operation of top dead center on track T1 (with reference to Fig. 1) seedling input port (omitting diagram) upward, from position K4 to position K5, by the seedling 22 that push-off pin 281 is released from leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, the seedling input port to cultivation device 7 falls, and supplies to plantation tool 11.Further, to the action of push-off pin 281, describe later further.

Then, along with from position K5 towards position K6, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, make attitude roughly downward before this with can be relative with next nursery hole 21 mode make attitudes vibration sharp, when moving to position K1, leading section 261Lp, 261Rp are inserted into new nursery hole 21.

The corresponding relation of the outline of the position on the track K of leading section 261Lp, 261Rp of the turned position of actuating arm 220 as shown in Figure 11 and extracting jaw 261L, 261R of a pair is known, from position K4 towards the action of position K5, can carry out more lentamente compared with the action of position K2 with from above-mentioned position K1, therefore, it is possible to carry out the taking-up of the seedling 22 from nursery hole 21 as soon as possible, and can reliably carry out the releasing of seedling 22 to cultivation device 7.

Carrying out such action, is because armite 230 is arranged in front (position of choosing of the tray supply apparatus 100) side of actuating arm 220.Further, actuating arm 220 is compared with armite 230, and the position of choosing of distance tray supply apparatus 100 is comparatively far away, therefore can not contact with seedling 22 when taking out seedling 22, can not counteract.

Then, to be mainly described centered by the action of transmission mechanism 290 and ejecting mechanism 280 with reference to Fig. 9, Figure 10, Figure 11.

As shown in Figure 9, by the rotation of actuating arm 220 to B direction, at the first gear 291 that the front end sidepiece 220a of actuating arm 220 is fixing, revolve round the sun to B direction centered by the rotating fulcrum 220b of actuating arm 220.First gear 291 is rotatably installed via the first turning cylinder 291a relative to armite 230, via the second gear 292, the 3rd gear 293 is rotated to B direction.3rd gear 293 is fixed with the leading section 245b of the first guided member 245 with camshaft 271 one, and edge 245a near the front end of the first guided member 245, the other end 230b of armite 230 links rotationally, therefore by the rotation of the 3rd gear 293, via camshaft 271, cam 270 rotates to B direction.That is, with the drive cycle of actuating arm 220 ordinatedly, cam 270 rotates.

Cam 270 has the peripheral part 272 of the varied in thickness because of place and the distance (external diameter) at axle center of distance camshaft 271 changes because of place outermost edge 273, as shown in Figure 10, in outermost edge 273, protuberance 273b external diameter compared with other parts 273a is larger, in the peripheral part 272 of axle center same distance being in distance camshaft 271, thickness unfertile land compared with the remaining thick wall part i.e. thickness of the second scope 272b of the first scope 272a sets.

Based on above formation, when cam 270 synchronously rotates with the drive cycle of actuating arm 220, leading section 261Lp, 261Rp of carrying out extracting jaw 261L, 261R of a pair from position K6 towards the on-off action of leading section 261Lp, 261Rp of extracting jaw 261L, the 261R of a pair during the action of position K1 and the action of push-off pin 281 as follows.

Namely, in the peripheral part 272 of cam 270, thick wall part i.e. the second scope 272b, limit projection 262L with the pawl nose width of pair of right and left, the front end face of 262R contacts, thus leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, overcome the recuperability of extension spring 263, the power in effect direction is away from each other 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 and extension spring keep the periphery portion contacts of the root bottom part with the first projection 283c, thus pushing arm extension spring 284 is drawn extension, pushing arm 283 rotates (reference arrow C) in Fig. 10 counterclockwise, maintains the state of push-off pin 281 retrogressing linked with connecting rod 282.

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

Then, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair carry out from position K1 towards the on-off action of leading section 261Lp, 261Rp of extracting jaw 261L, the 261R of a pair during the action of position K2 and the action of push-off pin 281 as follows.

Namely, in beginning from position K1 towards while the action of position K2, in the peripheral part 272 of cam 270; thin-walled portion i.e. the first scope 272a limits projection 262L with the pawl nose width of pair of right and left, the front end face of 262R contacts; thus leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair; by the recuperability of extension spring 263, move to approximating direction, the state that the leading section therefore becoming both sides is closed.

On the other hand, now, in the outermost edge 273 of cam 270, protuberance 273b still keeps the periphery portion contacts of the root bottom part with the first projection 283c with extension spring, thus pushing arm extension spring 284 is drawn extension, pushing arm 283 keeps the state (reference arrow C) of rotating counterclockwise in Fig. 10, maintains the state of push-off pin 281 retrogressing linked with connecting rod 282.Therefore, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, can keep the seedling 22 of taking-up securely, and keep this state to move to cultivation device 7 side gradually on leading section.

Then, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair carry out from position K4 towards the on-off action of leading section 261Lp, 261Rp of extracting jaw 261L, the 261R of a pair during the action of position K5 and the action of push-off pin 281 as follows.

Namely, in beginning from position K4 towards while the action of position K5, in the outermost edge 273 of cam 270, replace the other parts 273a of protuberance 273b, the periphery portion contacts of the root bottom part with the first projection 283c is kept with extension spring, thus pass through the recuperability of pushing arm extension spring 284, pushing arm 283 becomes the state (reference arrow D) of rotating clockwise instantaneously in Fig. 10, while the push-off pin 281 that pushing links with connecting rod 282, the notch 281b of the leading section 281a of push-off pin 281, while the extracting jaw 261L of extruding expansion a pair, the leading section of 261R is while mobile.

Thus, the seedling 22 released from leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair by the leading section 281a of push-off pin 281, the seedling input port to cultivation device 7 falls, and supplies to plantation tool 11.Now, the notch 281b of the leading section 281a of push-off pin 281, the leading section extruding extracting jaw 261L, 261R of expansion a pair moves, therefore, it is possible to remove the soil etc. that this leading section adheres to simultaneously.

Then, leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair carry out from position K5 towards the on-off action of leading section 261Lp, 261Rp of extracting jaw 261L, the 261R of a pair during the action of position K6 and the action of push-off pin 281 as follows.

Namely, in the peripheral part 272 of cam 270, replace thin-walled portion i.e. the first scope 272a, thick wall part i.e. the second scope 272b, limit projection 262L with the pawl nose width of pair of right and left, the front end face of 262R contacts, thus leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, overcome the recuperability of extension spring 263, the power in effect direction away from each other, the state change that the leading section to both sides is opened.

On the other hand, time near the K6 of in-position, in the outermost edge 273 of cam 270, replace other parts 273a, protuberance 273b and extension spring keep the periphery portion contacts of the root bottom part with the first projection 283c, thus pushing arm extension spring 284 is drawn extension, pushing arm 283 rotates (reference arrow C) in Fig. 10 counterclockwise, to the state change that the push-off pin 281 linked with connecting rod 282 retreats.

And, although in the above-described embodiment, the situation that extracting jaw 261L, 261R of a pair are formed with same metal plate member from root bottom part across leading section is integrated is illustrated, but be not limited thereto, for front, also can have flexible such as rubber slab or resin plate by unloading and form.Thus, even if clamp seedling 22 at leading section by the recuperability of extension spring 263, also rubber slab can be out of shape due to the elasticity of front, thus play the effect can not damaging seedling 22 by pressure.

And be configured to, push-off pin 281 is before leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair move near the K6 of position, cover the top of leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair, thus, can prevent when moving from position K5 to position K6, leaf hook on leading section 261Lp, 261Rp of extracting jaw 261L, 261R of a pair of the seedling 22 on pallet 20.

Further, retreat, thereby, it is possible to prevent the leaf of seedling 22 to be wound around on leading section 261Lp, 261Rp insertion speed when push-off pin 281 is configured to extracting jaw 261L, 261R of cooperation a pair leading section 261Lp, 261Rp insert nursery hole 21.

Then, referring again to Fig. 7, Fig. 8, be described further centered by the mechanism carrying tool 121 to drive off and on to make the pallet of tray supply apparatus 100.

As shown in Figure 8, pallet longitudinal conveying device 120, possesses: the pallet conveying tool 121 that (1) is above-mentioned; (2) the upper front end portion 121b1 of the both ends 121b of fixed tray conveying tool 121, the conveying tool arm 130 that the overshooting shape cam 131 that folk prescription has bending edge 131a bending is to the inside formed in bottom; (3) root bottom part 141 rotatably support on the side plate 110a of seedling carrying base 110, with the axle portion, front end 142 of leading section conveying tool arm 130 is rotatably supported on lower end edge portion by the first recess 143a, the second protuberance 143b, the 3rd recess 143c in side-looking time the conveying arm 140 that formed continuously smoothly; (4) from viewed from withdrawing device 200 side by longitudinal feed drive axle 151 that the driving force obtained from the power source of seeding transplant machine 1 is rotated to arrow E direction, 2 positions of the middle position of longitudinal feed drive axle 151 and right end position are fixed respectively, leading section rotatably has the longitudinal feed drive arm 150 pining down roller 152.Therefore, front end axle portion 142 is the rotating fulcrum axles linking pallet conveying tool 121.

Further, between the axle portion, front end 142 of the leading section of conveying arm 140 and the bottom 110a1 of the side plate 110a of seedling carrying base 110, to apply the mode of the power stretched all the time downwards to conveying arm 140, conveying arm extension spring 160 is installed.This conveying arm extension spring 160 is to the force tool of conveying arm 140 to the conveying of the conveying direction of action force of pallet conveying tool 121.Further, on the root bottom part 141 of conveying arm 140, the spring fitting bar 163 pin 132 that remains on and the upper end of conveying tool arm 130 is installed being installed another square end of the conveying tool arm extension spring 161 of a square end is fixed with.This conveying tool arm extension spring 161 is the force tools entered exerted a force to the side entering the gap 21b between nursery hole 21 centered by the axle portion, front end 142 becoming rotating fulcrum axle to pallet conveying tool 121.

Then, with reference to Fig. 7, Fig. 8, the action of the interval of pallet conveying tool 121 is described.

By the rotation of Endrem axle 171, seedling carrying base 110 right direction and arrow F direction (with reference to Fig. 7) are moved.Now, longitudinal feed drive axle 151 rotates to arrow E direction (with reference to Fig. 8).

Therebetween, withdrawing device 200 takes out seedling 22 in turn from the nursery hole 21 of right-hand member and supplies seedling 22 to cultivation device 7, and thereafter at the time point of seedling carrying base 110 to low order end movement, the seedling 22 in the nursery hole 21 of high order end is removed device 200 and takes out.Thus, whole seedling 22 of the horizontal stroke one row amount in nursery hole 21 is taken out.

Now be configured to, what the leading section of the longitudinal feed drive arm 150 fixed at the right-hand member of longitudinal feed drive axle 151 rotated to arrow E direction together with longitudinal feed drive axle 151 was rotatably installed pins down roller 152, after beginning with the contact of the first recess 143a of conveying arm 140, start the contact with the bending edge 131a of conveying tool arm 130 slightly late, therefore pallet conveying tool 121 along with the clockwise rotation of conveying arm 140 rise temporarily mobile after, start to rotate counterclockwise centered by the axle portion, front end 142 of leading section.

Namely, pallet conveying tool 121 is to arrow 121a0 (reference Fig. 7 (b), rise movement in direction Fig. 8) temporarily, thus the jut 121ab (with reference to Fig. 7 (b)) being held in the pallet conveying tool 121 of notch 112a (with reference to Fig. 7 (b)) before this deviates from from notch 112a, and the central portion 121a of the pallet conveying tool 121 that the gap 21a of the dorsal part before this in nursery hole 21 is standby, also rises mobile in the scope of this gap 21a on the direction of arrow 121a0.After this, conveying tool arm 130 starts to rotate counterclockwise centered by the axle portion, front end 142 of leading section, thus the central portion 121a of pallet conveying tool 121 moves to the direction of arrow 121a1 (with reference to Fig. 8).Further, the notch depth of notch 112a, is set as that the central portion 121a of pallet conveying tool 121 can the degree of movement in the scope of gap 21a.

After this, pin down roller 152 and continue further to rotate, then pin down roller 152 and continue the contact with the bending edge 131a of conveying tool arm 130, therefore the central portion 121a of pallet conveying tool 121 maintains and is positioned at the state of keeping out of the way groove 111a.Now, side by side pin down roller 152 to move from the first recess 143a of conveying arm 140 to the second protuberance 143b, therefore conveying arm 140 rotates clockwise further, the central portion 121a of pallet conveying tool 121, result maintains to be positioned at the state of keeping out of the way groove 111a, and the direction to arrow 121a2 (with reference to Fig. 8) is moved.

After this, pin down roller 152 to continue further to rotate, then while pining down roller 152 and carrying the bending edge 131a of tool arm 130 to be contactless state, by the recuperability of conveying tool arm extension spring 161, conveying tool arm 130 rotates instantaneously clockwise centered by the axle portion, front end 142 of leading section, thus the central portion 121a of pallet conveying tool 121, to the gap 21b being positioned at upside from gap 21a with a row amount in nursery hole 21, movement as shown in arrow 121a3.

After this, pin down roller 152 to continue further to rotate, then pin down roller 152 while contact while mobile with the 3rd recess 143c of conveying arm 140, therefore by the recuperability of conveying arm extension spring 160, conveying arm 140 is stretched downwards, the central portion 121a of pallet conveying tool 121, result maintains the state being positioned at gap 21b, and move to the direction of arrow 121a4 (with reference to Fig. 8), and the jut 121ab of the central portion 121a of pallet conveying tool 121 keeps on notch 112a.

And, to the central portion 121a of the pallet conveying tool 121 of the direction movement of arrow 121a4 (with reference to Fig. 8), maintain the state being positioned at the gap each other, nursery hole of the dorsal part in nursery hole 21, seedling carrying base 110 starts to move to arrow G direction, i.e. left direction, then withdrawing device 200 takes out seedling 22 in turn from the nursery hole 21 of left end and supplies seedling 22 to cultivation device 7, after this at the time point of seedling carrying base 110 to high order end movement, the seedling 22 in the nursery hole 21 of low order end is taken out with withdrawing device 200.Thus, whole seedlings 22 of the horizontal stroke one row amount in nursery hole 21 are taken out.

Further, therebetween, the jut 121ab of the central portion 121a of pallet conveying tool 121 keeps on notch 112a, therefore, it is possible to prevent from making pallet 20 offset motion downwards because entering the weight of the seedling 22 in nursery hole 21.

And, when whole seedlings 22 of the horizontal stroke one row amount in nursery hole 21 are taken out, then different from above-mentioned, what the leading section of the longitudinal feed drive arm 150 fixed in the middle position of longitudinal feed drive axle 151 was rotatably installed pins down roller 152, starts to carry the bending edge 131a of tool arm 130, the contact with the first recess 143a of conveying arm 140.

By repeating above-mentioned action, pallet 20 right direction or left direction move, and carry out longitudinal conveying off and on a row amount in nursery hole 21.

Thereby, it is possible to obtain compactly designed pallet longitudinal conveying device 120.Further, by the simple structure of guide rail 155, Endrem axle 171, pallet carrying road 111 movably can be supported.

And, the central portion 121a of pallet conveying tool 121, the planar portions 111b on pallet carrying road 111 configures, therefore pallet 20 can not bend as inner side, therefore at the dorsal part in nursery hole 21, can guarantee gap 21a, 21b of one fixed width, therefore pallet conveying tool 121 can reliably enter gap 21a, 21b.

Further, be provided with curved face part 111c in the downstream of the planar portions 111b on pallet carrying road 111, therefore pallet 20 bends along this curved surface.Therefore, when pallet is carried, when pallet conveying tool 121 moves to the direction of arrow 121a2, this flexure becomes resistance, can prevent pallet 20 from offseting to side, downstream.

Then, with reference to Figure 12, the various operating grip of configuration near handlebar grip 8L, the 8R of the pair of right and left at operating handle 8 and operating portion 600 are described.Figure 12 is various operating grip and the vertical view that is described of operating portion 600 of configuration near handlebar grip 8L, the 8R to the pair of right and left at operating handle 8.

As shown in figure 12, near the handlebar grip 8L on the left of operating handle 8, main clutch handle 80 is set, near the handlebar grip 8R on right side, is provided with the descending operation handle 81 making hydraulic lifting cylinder 10 action.

Descending operation handle 81 is configured to manually switch 3 stages into " decline ", " neutrality ", " rising ", when switching to " decline " position time, hydraulic lifting cylinder 10 declines and action to make running vehicle body 15, stop declining by sensor board 710 (with reference to Figure 13) described later, and if plantation break-make button 620 (with reference to Figure 12) described later is ON state, then planting clutch 420 is " leading to " state, starts to plant operation.

Further, when descending operation handle 81 being switched to " neutrality " position, then make plantation operation stop, when switching to " rising " position, then hydraulic lifting cylinder 10 rises and action to make running vehicle body 15.

Further, as shown in figure 12, on guidance panel 601, from its left end towards right-hand member sequentially, be configured with: (1) only makes the sky of plantation tool 11 action plant action button 610 under the state making the traveling of running vehicle body 15 stop; (2) when descending operation handle 81 is to the step-down operation position operation making running vehicle body 15 decline, switch to make plantation tool 11 action linkedly with this step-down operation state, not with the plantation break-make button 620 of any one state of the state of this step-down operation interlock; (3) display part 630 of plantation spacing in the rows is at least shown; (4) the adjustment button 640 of plantation spacing in the rows is at least regulated.

Further, plantation break-make button 620 is connected with sky with planting action button 610 connected in electrical series, therefore when planting action button 610 to sky and carrying out ON operation, also carries out ON operation to plantation break-make button 620, thus the action of plantation tool 11.

Here, display part 630 is described further.

In the seeding transplant machine 1 of present embodiment, by gear change hand lever 190, carry out " plantation 1 " of the plantation operation run at a low speed according to appointment or specify " plantation 2 " of carrying out the plantation operation of running at high speed, making the scope of displayable plantation spacing in the rows on display part 630 different.

Specifically, when gear change hand lever 190 being set as " plantation 1 (running at a low speed) ", the scope of the plantation spacing in the rows that operator can set is 22cm ~ 40cm, when gear change hand lever 190 being set as " plantation 2 (running at high speed) ", the scope of the plantation spacing in the rows that operator can set is 32cm ~ 70cm, but can in the storage part 810 of control part 800 initial setting in advance.These initial setting values are configured to change respectively.Such as be configured to, when changing the velocity ratio of " plantation 1 " and " plantation 2 ", in operating portion 600, after switching to the pattern that the scope of plantation spacing in the rows is changed, adjustment in use button 640, can to the scope separately change setting of plantation spacing in the rows.

In the present embodiment, judge that gear change hand lever 190 is set as " plantation 1 " and " plantation 2 " any one control part 800 (reference Figure 14) according to the output signal from the first varying speed switch 198 and the second varying speed switch 199, the instruction corresponding with this result of determination is exported to display part 630.Thus, the scope of the plantation spacing in the rows that operator can set is shown.

Namely be configured to, in the region, left side of display part 630, side by side show scope and the upper and lower bound of the plantation spacing in the rows that operator can set, and on right-hand part region, the median of plantation spacing in the rows is shown as nonce.

In the scope of the plantation spacing in the rows that operator shows on the viewing area, left side of display part 630, in order to the nonce shown on the right-hand part viewing area of display part 630 is changed to required spacing in the rows, operation regulates button 640.

Like this in order to realize the plantation spacing in the rows set by operator, control part 800 utilizes (i) by regulating the numerical information of the plantation spacing in the rows of button 640 setting; (ii) judge to set " plantation 1 " and " planting 2 " any one the presence or absence of the ON signal from the first varying speed switch 198 and the second varying speed switch 199 by gear change hand lever 190, decision is used for making plantation clutch 420 to be action cycle of the solenoid 470 of " leading to " state, according to the action cycle of this decision, solenoid 470 is energized.

Thus, utilize the display part 630 that can show the scope of planting spacing in the rows corresponding with the travel speed of being specified by gear change hand lever 190 (" planting 1 (low speed) ", " planting 2 (at a high speed) "), thus operator in the scope of the plantation spacing in the rows corresponding with the travel speed of specifying, can set suitable plantation spacing in the rows.

Such as, when travel speed being set as slower pattern, plant with narrower plantation spacing in the rows.Therefore, the responsiveness of plantation tool can not be too fast, therefore, it is possible to realize the raising of plantation precision.Further, travel speed is set as faster pattern time, plant with wider plantation spacing in the rows.Therefore, it is possible to make operating efficiency improve.

Namely, seeding transplant machine 1 according to the present embodiment, such as when wanting to plant with narrower plantation spacing in the rows, the travel speed that slows down and make the responsiveness of plantation tool can not be too fast, the raising of planting precision can be realized, when wanting to plant with wider plantation spacing in the rows, can travel speed be accelerated and operating efficiency be improved.

Further, can with the operating condition such as farmland or travel speed accordingly, be set as suitable plantation spacing in the rows.

That is, such as, when carrying out plantation operation obliquely, on up-wards inclination face and decline inclined plane, in order to realize identical plantation spacing in the rows, the setting of the plantation spacing in the rows of carrying out the skidding considering running vehicle body 15 is needed.In the present embodiment, in " plantation 1 " and " plantation 2 ", in the scope of the plantation spacing in the rows corresponding with both sides, the scope that setting is overlapping, thus on up-wards inclination face and decline inclined plane, identical plantation spacing in the rows can be realized.

Specifically, in the present embodiment, the scope of overlapping plantation spacing in the rows is 32cm ~ 40cm.Therefore, on up-wards inclination face, consider to skid, gear change hand lever 190 is set as " plantation 2 (at a high speed) " that can run at high speed, plantation spacing in the rows is set as 33cm.

On the other hand, in decline inclined plane, consider to skid, gear change hand lever 190 is set as " plantation 1 (low speed) " that can run at a low speed, plantation spacing in the rows is set as 30cm.

Thus, actual plantation spacing in the rows, up-wards inclination face can realize 31.5cm, can realize 31.5cm in decline inclined plane.

Further, in " plantation 1 " and " plantation 2 ", making the adjustable range of plantation spacing in the rows different, except reply rise and fall obliquely, also there is the quickening travel speed when planting with wider spacing in the rows and effect that operating efficiency is improved.

Further, the storage part 810 of present embodiment, is equivalent to an example of storage part of the present invention, the control part 800 of present embodiment, is equivalent to an example of determination section of the present invention.Further, the adjustment button 640 of present embodiment, is equivalent to an example of spacing in the rows switching part of the present invention.

Here, the explanation of guidance panel 601 is again got back to.That is, according to above-mentioned formation, plantation break-make button 620 configures near the central portion of guidance panel 601, is therefore easy to operation.

Further, sky is planted action button 610 and is configured in the left side of the 601b below different from the upper surface 601a of other action button of configuration, therefore, it is possible to the maloperation of minimizing operator.

Further, display part 630 configures near the central authorities of guidance panel 601, therefore easily confirms.

Regulate button 640 possess in upside to expand spacing in the rows direction change " risings " press compress switch 640a and possess in downside to reduce spacing in the rows direction change " decline " press the 640b that compresses switch.

According to above-mentioned formation, operate " rising " by the 640a that compresses switch, " decline " by the 640b that compresses switch, thus will represent that the numerical value of spacing in the rows directly shows on display part 630, therefore operator easily recognizes spacing in the rows.

Then, main with reference to Figure 13, Figure 14, with the operation based on planting depth guiding mechanism 700, plantation break-make button 620, descending operation handle 81 etc., be described centered by the control part 800 controlling to carry out the action of solenoid 470 grade of the break-make of planting.

Figure 13 is the left side view of the schematic configuration representing planting depth guiding mechanism 700, and Figure 14 illustrates the schematic block diagram to the input and output on control part 800.

As shown in figure 13, planting depth guiding mechanism 700, possesses: (1) is by contacting the sensor board 710 of the bottom surface broad warp planting depth of seedling being kept certain with face, farmland 701; (2) as the plate-shaped member being roughly L-shaped shape during side-looking, the bend of L word is supported relative to running vehicle body 15 rotationally by rotation support shaft 721, the end 722 rearward extended rotatably links via rotation support shaft 722a with the leading section 711 of sensor board 710, and the other end 723 extended upward, the degree of depth arm 720 rotatably linked with the leading section 741 transmitting operator's manually transmission lever 740 of degree of depth handle 730 action of the position in vertical (up and down) direction of operating and setting sensor board 710; (3) by spring 750 that degree of depth arm 720 rotatably hangs from main frame 17; (4) as the plate-shaped member being roughly L-shaped shape when side-looking, the bend of L word is supported relative to running vehicle body 15 rotationally by rotation support shaft 761, elongated hole 762 is formed in the bottom of rotation support shaft 761, and by the extension spring 766 linked with upper end 763, exert a force in order to rotation support shaft 761 is rotated as axle core to arrow Y-direction, relative to the descending operation valve (omitting diagram) that hydraulic switching valve portion 40 possesses, the reverse arm 760 that leading section 764 links with bar 765; (5) detect with break-make the front mode that handle 771 is positioned at the elongated hole 762 of reverse arm 760, the plantation switch 770 of configuration on reverse arm 760; (6) the connecting pin 781a at one end portion 781 arranged inserts in elongated hole 762, the rodmeter 780 that the other end 782 rotatably links with the upper end 712 of sensor board 710 via connection shaft 783.

And be configured to, the swing interlock of the arrow Z-direction of the upper end 712 of the sensor board 710 that rodmeter 780 causes with the swing to the upper direction of sensor board 710, thus the direction that edge, the front end 781b of one end 781 detects handle 771 to pushing break-make is moved, plantation switch 770 is made to be ON.

According to above-mentioned formation, degree of depth arm 720 is suspended in midair by spring 750, therefore, it is possible to eliminate rocking of the linking portion of degree of depth arm 720 and degree of depth handle 730, the degree of depth set by degree of depth handle 730 is stablized.Further, although spring 750 is formations of suspention degree of depth arm 720, being not limited thereto, such as, also can be by the formation of degree of depth arm 720 to main frame thruster pressure.

Further, according to above-mentioned formation, reverse arm 760 is stretched by extension spring 766 on the direction of pushing sensor board 710, therefore, it is possible to eliminate rocking of rodmeter 780 and reverse arm 760.

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

Then, be described with reference to the control method of Figure 14 to the control part 800 pairs of solenoids 470 arranged in the below of guidance panel 601.

As shown in figure 14, be configured in control part 800, at least input make-and-break signal, the switching signal of descending operation handle 81, the make-and-break signal from plantation switch 770 from plantation break-make button 620, by these input signals, to solenoid 470 output pulse signal.

Based on above formation, main with reference to Figure 12 ~ Figure 14, be described centered by the action of control part 800.

Here, after seeding transplant machine 1 is moved to the assigned position in farmland, (1) is divided into will to start to plant the scene of operation; Thereafter (2) while plant operation while the scene of traveling in farmland; And the scene that (3) turn back to the end on ridge is described.

(1) scene of planting operation to be started:

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

Further, gear change hand lever 190 is set as " plantation 1 " by operator.Thus, the first varying speed switch 198 is ON, and the second varying speed switch 199 is OFF, is only carried to control part 800 by ON signal from the first varying speed switch 198.Control part 800 accepts the ON signal from the first varying speed switch 198, and the ON signal do not accepted from the second varying speed switch 199, therefore setting " plantation 1 (low speed) " is judged to be, read the scope " 22cm ~ 40cm " of the plantation spacing in the rows corresponding to " plantation 1 (low speed) " prestored in storage part 810, the viewing area, left side of display part 630 shows.

Operator observes the scope of the plantation spacing in the rows of display on display part 630, after the plantation spacing in the rows needed for confirming and 50cm do not enter this scope, operates gear change hand lever 190, switches to " plantation 2 (at a high speed) ".Like this, specifically on the viewing area, left side of display part 630, the scope " 32cm ~ 70cm " of display plantation spacing in the rows, and as the nonce display 51cm of plantation spacing in the rows on right-hand part viewing area.

Operator presses and regulates button 640, and the 51cm of nonce is changed to the 50cm needed for oneself.Thus, the setting of plantation spacing in the rows is completed.

Then, descending operation handle 81 is operated to " decline " position by operator, reduces the overall height of running vehicle body 15, thus sensor board 710 is declined towards face, farmland 701 together with running vehicle body 15.

When sensor board 710 contacts with face, farmland 701, then the leading section 711 of sensor board 710 rotates to arrow Z-direction (with reference to Figure 13), therefore the direction that edge, the front end 781b of rodmeter 780 detects handle 771 to pushing break-make is moved, make plantation switch 770 for ON, thus the ON signal from plantation switch 770 is inputted to control part 800.

Control part 800 accepts from plantation break-make button 620 signal representing " leading to " state under AND condition, the signal representing " decline " position is accepted from descending operation handle 81, accept " ON " signal from plantation switch 770, thus export the signal that solenoid 470 is energized.

Thus, plantation clutch 420 switches to " leading to " state from " breaking " state, starts to plant operation.

Namely be configured to, control part 800 accepts above-mentioned various signal, when being judged as satisfied plantation condition, first plantation clutch 420 is switched to " leading to " state, make plantation tool 11 action, therefore, when operator carries out operation etc. to descending operation handle 81 and starts to plant operation, plantation tool 11 plants the first young plant immediately.Thereby, it is possible to plant action from the end of farmland.

Further, the formation comprising sensor board 710 and plantation switch 770 of present embodiment, is equivalent to an example in height detection portion of the present invention.

(2) while carry out planting operation while the scene of traveling in farmland:

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

Further, pulse signal, relative to solenoid 470, in order to the energising of the action cycle of regulation, exports with its action cycle by control part 800.Therefore, plantation clutch 420 be energized by solenoid 470 and become " lead to " state, and interval cam 441 start rotation carry out 1 rotation after terminate (terminating after namely carrying out the plantation action of a seedling) then repeats to return " breaking " state a series of action with this action cycle.

Thereby, it is possible to carry out plantation operation off and on, the plantation spacing in the rows needed for realization.

Here, the action cycle of regulation, the travel speed corresponding based on " plantation 2 (at a high speed) " of being specified by operator and the value of plantation spacing in the rows selected by operator and 50cm, determined by control part 800.Further, the action cycle of regulation is counted by the timer in control part 800.

According to the knee-action of sensor board 710, hydraulic lifting cylinder 10 carries out following action.

Namely, when sensor board 710 is moved upward, then the leading section 711 of sensor board 710 moves to arrow Z-direction centered by rotation support shaft 722a, and when the connecting pin 781a arranged on an end 781 of rodmeter 780 moves to the direction of exterior region of pushing elongated hole 762, then oppositely arm 760 rotates for axle core in fig. 13 clockwise with rotation support shaft 761, the descending operation valve (omitting diagram) that this action possesses to hydraulic switching valve portion 40 via bar 765 transmits, to the direction action that hydraulic lifting cylinder 10 extends, the overall height of running vehicle body 15 raises.

On the other hand, when sensor board 710 moves downwards, the leading section 711 of sensor board 710 moves to the direction contrary with arrow Z-direction centered by rotation support shaft 722a, and the connecting pin 781a arranged on an end 781 of rodmeter 780 to from the exterior region of elongated hole 762 away from direction move, the tensile force being then subject to extension spring 766 makes reverse arm 760 rotate to arrow Y-direction for axle core with rotation support shaft 761, the descending operation valve (omitting diagram) that this action possesses to hydraulic switching valve portion 40 via bar 765 transmits, to the direction action that hydraulic lifting cylinder 10 shortens, the overall height of running vehicle body 15 reduces.

By above-mentioned action, even if having concavo-convex on face, farmland 701, also the planting depth of seedling can be kept certain.

(3) to the scene that ridge end is turned back:

Under this scene, operator plants operation to interrupt, and descending operation handle 81 is moved from " decline " position to " neutrality " position.

Thus, control part 800 accepts the signal of expression " neutrality " position from descending operation handle 81, stops the output of the pulse signal to solenoid 470.Thus, after plantation clutch 420 switches to " breaking " state from " leading to " state, maintain " breaking " state continuously, thus interrupt plantation operation.

And then operator turns back towards adjacent ridge to make running vehicle body 15, descending operation handle 81 is moved to " rising " position from " neutrality " position.

With the action of the cable 82 corresponding to the operation of this descending operation handle 81 linkedly, descending operation valve (the omitting diagram) action that hydraulic switching valve portion 40 possesses, the direction of extending to hydraulic lifting cylinder 10 is moved, thus the overall height of running vehicle body 15 raises.

Now, sensor board 710 declines, and plantation switch 770 is OFF state, can not export any signal from control part 800.

Further, plantation clutch 420 maintains " breaking " state, continues the state that plantation operation is interrupted.

Therefore operator makes running vehicle body 15 turn back.

Then, operator make descending operation handle 81 from " rising " position through " neutrality " position moves to " decline " position, then with the action of the cable 82 corresponding to the operation of descending operation handle 81 linkedly, the descending operation valve events that hydraulic switching valve portion 40 possesses, the direction of shortening to hydraulic lifting cylinder 10 is moved, thus starts to make the overall height of running vehicle body 15 to reduce.Further, by the aforesaid operations of descending operation handle 81, will represent that the signal that descending operation handle 81 is in " decline " position exports to control part 800.

Further, the car body of running vehicle body 15 is fallen, and after sensor board 710 contacts with face, farmland 701 soon, then in the same manner as situation about illustrating in above-mentioned project (1), plantation switch 770 is ON, by this signal input control portion 800.

Plantation break-make button 620 keeps " leading to " state, therefore control part 800 accepts from plantation break-make button 620 signal representing " leading to " state in AND condition, the signal representing " decline " position is accepted from descending operation handle 81, accept " ON " signal from plantation switch 770, thus export the signal that solenoid 470 is energized.That is, control part 800 as described above, relative to solenoid 470, in order to the energising of the action cycle of regulation, exported by pulse signal with this action cycle.

Thus, plantation clutch 420 switches from " breaking " state to " leading to " state, again starts to plant operation.

And be configured to, in this case, when operator carries out operation etc. to descending operation handle 81 and again starts to plant operation, the count resets of the timer in control part 800, therefore on next ridge, plantation tool 11 also can plant the first young plant immediately.Thereby, it is possible to plant action all the time from the end of farmland.

According to above-mentioned formation, plantation break-make button 620 is placed in " leading to " state, only descending operation handle 81 is operated, start above-mentioned (1) plantation operation, after this (2) while carry out plantation operation while travel in farmland, and (3) after turning back to ridge end, again carry out a series of operations such as plantation operation continuously.

Then, to the formation configuring hydraulic pump 850 between engine 12 and gearbox 4 (Fig. 2 reference), the main Figure 15 that uses is described.Figure 15 is the end view be described the formation configuring hydraulic pump 850 between engine 12 and gearbox 4.

(vi) extension spring 545 installed between spring steady pin 544 and body side.

Further, the switching device shifter 510 of present embodiment is equivalent to an example of conveying capacity switching device shifter of the present invention, and the driven wheel 511 of present embodiment is equivalent to an example of driven wheel of the present invention.Further, the switching power transmission shaft 520 of present embodiment is equivalent to an example of switching power transmission shaft of the present invention, and the first change gear 512a of present embodiment, the second change gear 512b are equivalent to an example of the change gear of 2 groups of the present invention.Further, the sliding handle 540 of present embodiment is equivalent to an example of sliding handle of the present invention, and the extension spring 545 of present embodiment is equivalent to an example of spring members of the present invention.

The handle part 540a of sliding handle 540, as shown in figure 21, when configuring upward, sliding pin 543 is in oblique top-left position (being represented by dotted lines in figure 21) in figure 21, inner side inwall 522b in the groove portion 522 by switching power transmission shaft 520, to (the moving range W with reference to the inner side inwall 522b in the groove portion 522 of Figure 21) under the state of inner side press-in, illustrates and switches the state that power transmission shaft 520 slides into gauge on the direction of the N of arrow shown in Figure 19, Figure 21.In this condition, the jut 521 (with reference to Figure 19) switching power transmission shaft 520 is chimeric with the recess of the second change gear 512b.

On the other hand, when the handle part 540a of sliding handle 540 is rotated 180 ° to the direction of the S of arrow shown in Figure 21, sliding pin 543 is in figure 21 to oblique bottom-right location (representing with double dot dash line in Figure 21) mobile (the moving range V with reference to the sliding pin 543 of Figure 21), thus under the state extruded to outermost by the outside inwall 522a in groove portion 522 switching power transmission shaft 520 at sliding pin 543, become the state that switching power transmission shaft 520 slides into gauge on the direction of the M of arrow shown in Figure 19.In this condition, the jut 521 switching power transmission shaft 520 is chimeric with the recess of the first change gear 512a.

Like this, when the handle part 540a of sliding handle 540 be positioned at just go up time, via the second change gear 512b, Endrem axle 171 is to slowly run, when the handle part 540a of sliding handle 540 be positioned at just descend time, via the first change gear 512a, Endrem axle 171 is with high-speed rotation.And, on from sliding handle 540 to the operational transmission paths of switching power transmission shaft 520, what formation was made up of the width in the groove portion 522 larger than the external diameter of sliding pin 543 gets around regulations mechanism, become sliding pin 543 formation that pushing outside inwall 522a or inner side inwall 522b makes switching power transmission shaft 520 slide from the rotating operation way of sliding handle 540, with the slippage of sliding handle 540 independently, the operational stroke (rotating operation angle) of sliding handle 540 is set as required 180 degree.

Therefore, after switch speed, sliding handle 540 can not laterally fly out, and therefore can not counteract.

Further, above-mentioned mechanism of getting around regulations, except being made up of the width in groove portion 522 as described above, also can be made up of the elongated hole contacting the arc-shaped of operation to sliding pin 543 from sliding handle 540.Further, above-mentioned elongated hole forms the arc-shaped centered by back shaft 542 on sliding handle 540, also can be the formation inserting sliding pin 543.In this formation, sliding handle 540 rotates centered by rotating fulcrum 541, but does not fix with back shaft 542.And, the leading section of sliding pin 543 inserts the groove portion 522 of switching power transmission shaft 520 slidably (when this formation, the width of the groove in groove portion 522 can be the degree that the front end of sliding pin 543 is inserted slidably), and the foundation portion of sliding pin 543, as mentioned above, the elongated hole that sliding handle 540 is formed is inserted in.In addition, sliding pin 543 is fixing on the outer peripheral face of back shaft 542.Further, when sliding pin 543 rotates, in order to avoid interfering, the first above-mentioned gripper shoe 542a and the second gripper shoe 542b (with reference to Figure 20) is formed with gap aptly.

According to this formation, when making sliding handle 540 rotate, then elongated hole rotates simultaneously, with from the rotating operation of sliding handle 540 way, the foundation portion of sliding pin 543 push to the inwall of a side side of elongated hole or the inwall of the opposing party side and rotates side by side together with back shaft 542, inwall 522a or inner side inwall 522b outside the leading section pushing of sliding pin 543 and switching power transmission shaft 520 is slided.

Further, on the surface of sliding handle 540 by the display of the transporting velocity of Endrem axle 171 with 2 kinds, mode that above-below direction is contrary respectively shows.When sliding handle 540 upwards configures, be in the numeral that can read " 200 " towards, mean the lateral transfer amount of the seedling carrying base 110 that the spacing in the nursery hole 21 of the transverse direction of the seedling pallet (vertical 20 arrange × horizontal stroke 10 arrange) being set as offering 200 caves with nursery hole 21 on direction in length and breadth coordinates.

And, when sliding handle 540 configures downwards, be in the numeral that can read " 128 " towards, mean the lateral transfer amount of the seedling carrying base 110 that the spacing in the nursery hole 21 of the transverse direction of the seedling pallet (vertical 16 arrange × horizontal stroke 8 arrange) being set as offering 128 caves with nursery hole 21 on direction in length and breadth coordinates.

Thus, from numerical monitor towards, set lateral transfer amount can be understood intuitively, be easy to differentiate.

Here, the extension spring 545 installed between spring steady pin 544 and body side is described further.

Jut 521 is such as when chimeric with the recess of the first change gear 512a or the second change gear 512b, and the mutual alignment in rotation direction cannot be fitted together to before coordinating.Therefore, when not arranging extension spring 545 temporarily, operator, before both sides position coordinates, must push sliding handle 540.Further, sliding handle 540 grade then may be caused when excessively pushing damaged.

Therefore be configured to, by arranging above-mentioned extension spring 545, during position above or below sliding handle 540 is set in, before jut 521 is chimeric with the recess of the first change gear 512a or the second change gear 512b, in order to temporarily maintain standby state, the tensile force of extension spring 545 acts on to steady pin 544, therefore when both sides position coordinates, by this tensile force, the Qian He of jut 521 and recess can be carried out safely and reliably.Further, extension spring 545 is formations that substantial middle (sliding handle 540 is towards the attitude of general horizontal direction) between the top position and lower position of sliding handle 540 crosses dead point.

According to above formation, accept the driven wheel 511 of power from transmission gear 184 via sprocket wheel 183, relative to switching power transmission shaft 520 spline joint, therefore make switching power transmission shaft 520 rotate.

After this, operator, when being set upward by sliding handle 540, by slip travel mechanism 530, makes switching power transmission shaft 520 towards inner side (the arrow N with reference to Figure 19) gearshift.Thus, switching the jut 521 that the outer surface of power transmission shaft 520 is formed, to the second change gear 512b side gearshift, therefore to the jut 521 of equidirectional gearshift, chimeric with the recess of the second change gear 512b, switch the rotation of power transmission shaft 520, via the second change gear 512b, transmit to large diameter gear 185b, Endrem axle 171 slowly runs.

On the other hand, operator, when being set by sliding handle 540, by slip travel mechanism 530, makes switching power transmission shaft 520 (the arrow M with reference to Figure 19) gearshift laterally downwards.Thus, switching the jut 521 that the outer surface of power transmission shaft 520 is formed, to the first change gear 512a side gearshift, therefore to the jut 521 of equidirectional gearshift, chimeric with the recess of the first change gear 512a, switch the rotation of power transmission shaft 520, via the first change gear 512a, transmit to small-diameter gear 185a, Endrem axle 171 high-speed rotation.

Then, Figure 22 is used to be described pallet pressing device 920.

Figure 22 is the summary side elevation of the pallet pressing device 920 for illustration of present embodiment 2.

As shown in figure 22, pallet pressing device 920 is configured to possess:

I () is coerced lateral shift that arrange, that prevent the position on the transverse direction of pallet 20 from offseting on two of pallet carrying road 111 and is prevented guide plate 921;

(ii) prevent from lateral shift the side of guide plate 921 erecting and the block shaft 922 of fixing;

(iii) end is rotatably installed in block shaft 922, and the other end prevents guide plate 921 from oliquely downward extending along lateral shift, and the leading section 923a of this other end bends to (in fig. 22 on front side of hand to the inside bending) first push plate 923 of roughly L-shaped to prevent cross-section on the upper end edge portion 921a of guide plate 921 in lateral shift;

(iv) end is rotatably installed in block shaft 922, and the other end extends to the oblique upper of the columned pin 132 that the upper end at conveying tool arm 130 is installed, and the second push plate 924 that the lower end edge portion 924a near the central authorities an of end and the other end abuts with the outer peripheral face of columned pin 132;

V () is as the spring members of the scroll of winding in block shaft 922, the power in the direction that one square end 925a rotates when being provided in Figure 22 side-looking to the first push plate 923 counterclockwise, and to the pallet pushing spring 925 of the power in the direction that counter-rotational, lower end edge portion 924a clockwise abuts with columned pin 132 when another square end 925b is provided in Figure 22 side-looking to the second push plate 924.

Further, pin 132 has the function of the fulcrum of the square end installing conveying tool arm extension spring 161 concurrently, makes the function of the cam of the second push plate 924 action.

And, in present embodiment 2, when pallet carrying road 111 sets pallet 20, edge, the periphery 20a in flange shape pallet 20 outstanding is laterally with the formation of the state clamped between the lower edge section 923b of the leading section 923a preventing upper end edge portion 921a, the roughly L-shaped of guide plate 921 from bending in lateral shift configuration.

Further, the pallet pressing device 920 of present embodiment is equivalent to an example of pallet pressing device of the present invention, and the second tray supply apparatus 100 of present embodiment is equivalent to an example of tray supply apparatus of the present invention.

In above formation, then the action of pallet pressing device 920 is described with reference to Figure 22.

Here, after pallet carries the jut 121ab of tool 121 (with reference to Fig. 7 (b)) to deviate from from notch 112a, (1) pallet is divided into carry the central portion 121a of tool 121 to the scene of the direction movement of arrow 121a1 (with reference to Figure 22); (2) scene to the direction movement of arrow 121a3 (with reference to Figure 22) is described.

(1) to the scene of the direction movement of arrow 121a1 (Figure 22 reference):

Conveying tool arm 130 counterclockwise starts to rotate centered by axle portion, front end 142, thus the central portion 121a of pallet conveying tool 121 moves to the direction of arrow 121a1 (with reference to Figure 22).

Thus, the central portion 121a of pallet conveying tool 121 deviates from from the gap 21a of pallet 20, therefore pallet 20 because of deadweight offset motion downwards.

On the other hand, counterclockwise start to rotate side by side centered by axle portion, front end 142 with conveying tool arm 130, the pin 132 installed in the upper end of conveying tool arm 130 counterclockwise rotates centered by axle portion, front end 142, thus make the second push plate 924 of being abutted with the outer peripheral face of pin 132 by the recuperability of pallet pushing spring 925, counterclockwise rotate centered by block shaft 922.

When second push plate 924 is counterclockwise rotated, the pallet pushing of scroll another square end 925b of spring 925, direction to this scroll wraps that reels further is moved, therefore this square end 925a is relative to the lower edge section 923b of the leading section 923a of the first push plate 923, and the direction to the pushing force of edge, the periphery 20a to reinforced tray 20 acts on.

Thereby, it is possible to stop the action of pallet 20 changing of the relative positions downwards because of deadweight.

(2) to the scene of the direction movement of arrow 121a3 (with reference to Figure 22):

While pining down roller 152 and carrying the bending edge 131a of tool arm 130 to be contactless state, conveying tool arm 130 is by recuperability clockwise instant rotation centered by axle portion, front end 142 of conveying tool arm extension spring 161, thus the central portion 121a of pallet conveying tool 121, to the gap 21b being positioned at upside from gap 21a with a row amount in nursery hole 21, mobile as shown in arrow 121a3 (with reference to Figure 22).

Thus, the central portion 121a of pallet conveying tool 121 reliably inserts the gap 21b of pallet 20, and pallet 20 proceeds to conveying action downwards.

On the other hand, by carrying the recuperability of tool arm extension spring 161, centered by axle portion, front end 142, clockwise instant rotation is side by side with conveying tool arm 130, at the pin 132 that the upper end of conveying tool arm 130 is installed, rotate clockwise centered by axle portion, front end 142, thus by the second push plate 924 that pallet pushing abuts with the outer peripheral face of pin 132 by the recuperability of spring 925, rotate clockwise centered by block shaft 922.

When the second push plate 924 rotates clockwise, the pallet pushing of scroll another square end 925b of spring 925, direction to this scroll wraps of release is moved, therefore this square end 925a is relative to the lower edge section 923b of the leading section 923a of the first push plate 923, to the direction effect of the pushing force on edge, the periphery 20a relaxing pallet 20.

Thus, when pallet conveying tool 121 is mobile to the direction (with reference to Figure 22) of arrow 121a4, pallet 20 can be carried downwards smoothly.

According to formation described above, can prevent pallet 20 from falling because weight offsets downwards.

And, because the first push plate 923 pushes edge, the periphery 20a of pallet 20, therefore independently push with the size of the seedling pallet (vertical 20 arrange × horizontal 10 arrange) above-mentioned nursery hole 21 being offered on direction in length and breadth 200 caves or the pallet 20 such as seedling pallet (indulge 16 to arrange × horizontal stroke 8 arrange) of offering 128 caves.

Further, the lower edge section 923b due to the leading section 923a by the first push plate 923 pushes edge, the periphery 20a of pallet 20, is therefore simple structure and pallet 20 not easily skids.

(embodiment 3)

In present embodiment 3, to other configuration example i.e. the 3rd gear mechanism 2182 outside the second gear mechanism 1182 (with reference to Figure 19) on the second tray supply apparatus 100 of the second seeding transplant machine 101 illustrated in above-mentioned embodiment 2, accompanying drawing is used to be described its formation and action.

In the 3rd gear mechanism 2182 of present embodiment 3, the formation identical to the second gear mechanism 1182 with above-mentioned embodiment 2 marks same-sign and the description thereof will be omitted.

Figure 23 is the amplification partial sectional view for being described the power transfer path in the 3rd gear mechanism 2182 of present embodiment 3.

Further, Figure 23 is the figure of the bang path being mainly used in clearly demonstrating power, and therefore seedling transmission driving box 180 or sliding handle 540 do not represent in the drawings.Further, Figure 23 and Figure 19 is similarly the figure of the section being equivalent to the part of A1-A2-A3 shown in Figure 20.

As shown in figure 23, 3rd gear mechanism 2182 of present embodiment 3 is with the main distinction point of the second gear mechanism 1182 of above-mentioned embodiment 2, in the second gear mechanism 1182, the jut 521 being switching power transmission shaft 520 is chimeric with the recess of the first change gear 512a, or the formation chimeric with the recess of the second change gear 512b (with reference to Figure 19), and be configured in the 3rd gear mechanism 2182 of present embodiment 3, with another switch power transmission shaft 1520 glide direction (with the arrow M direction of Figure 23 and arrow N direction corresponding) the groove 1521 of cylindrical shape that formed orthogonally of axle core in the ball parts 1523 that pushed laterally all the time by Compress Spring 1522, chimeric with the recess 1512a of the first change gear 512a, or it is chimeric with the recess 1512b of the second change gear 512b.

Be described centered by above-mentioned distinctive points referring to Figure 23.

As shown in figure 23, accepting the driven wheel 511 from transmitting the driving force that gear 184 transmits, switching power transmission shaft 1520 spline joint relative to another, and with the first change gear 512a for benchmark, switch the end edge portion 523 side configuration of power transmission shaft 1520 at another.Further, with the first change gear 512a for benchmark, the contrary side of the end edge portion 523 of power transmission shaft 1520 is being switched with another, by col-lar part 1524 via adjacent configuration second change gear 512b therebetween.Col-lar part 1524 inserts the parts that another switches the ring-type of power transmission shaft 1520, on the both ends of this annular inner circumferential side, is formed with conus portion 1524a, 1524b with the makes point contact of ball parts 1523.

Further, ball parts 1523 diameter than the width of the first change gear 512a and the width of the second change gear 512b large.

In addition, when ball parts 1523 are chimeric with the recess 1512a of the first change gear 512a, time chimeric with the recess 1512b of the second change gear 512b, in various situation, be all that the center of ball parts 1523 switches than another formation that surface of power transmission shaft 1520 is positioned at inner side.

Then, the action of ball parts 1523 is described with reference to Figure 23.

(1) by sliding handle 540 to the direction operation contrary with arrow S (with reference to Figure 21), another switches power transmission shaft 1520 start to slide movement to N direction (with reference to Figure 23) time:

Original state is now in the partial insertion groove 1521 of more than the half portion of ball parts 1523, and remainder is pressed into the state (the ball parts 1523 with reference to solid line in fig 23 represents) of the recess 1512a of the first change gear 512a.That is, the first change gear 512a switches with another state that power transmission shaft 1520 engages.

In above-mentioned state, when another switching power transmission shaft 1520 starts to slide mobile to N direction, slip with groove 1521 is moved, ball parts 1523 also side by side slide movement, and ball parts 1523 move along the conus portion 1524a of col-lar part 1524, overcome Compress Spring 1522 screen resilience and be pressed into the direction, inner side of groove 1521.

Thus, ball parts 1523 are deviate from completely from the recess 1512a of the first change gear 512a, therefore the first change gear 512a and another switch the engagement releasing of power transmission shaft 1520.

(2) when proceed sliding handle 540 (with reference to Figure 20) with arrow S-phase in the other direction on operation, another switches power transmission shaft 1520 continue to slide movement to N direction time:

Another switching power transmission shaft 1520 continues further to N direction to slide and moves, thus further slip of groove 1521 moves the movement and ball parts 1523 also slide.And, when ball parts 1523 move gradually to the position of the second change gear 512b, by the screen resilience of Compress Spring 1522, ball parts 1523 extrude to the gap of the recess 1512b of the second change gear 512b (with reference in fig 23 with the ball parts 1523 that double dot dash line represents).That is, the second change gear 512b switches via ball parts 1523 and another state that power transmission shaft 1520 engages.

Thus, the transmission of rotary driving force on Endrem axle 171, switches from the first change gear 512a to the second change gear 512b.

(3) when sliding handle 540 is started to slide mobile to M direction (with reference to Figure 23) to arrow S (with reference to Figure 21) direction operation, another switching power transmission shaft 1520:

Original state is now the second change gear 512b switches via ball parts 1523 and another state (with reference in fig 23 with the ball parts 1523 that double dot dash line represents) that power transmission shaft 1520 engages.

In above-mentioned state, when another switching power transmission shaft 1520 starts to slide mobile to M direction, slip with groove 1521 is moved, ball parts 1523 also slide movement simultaneously, and ball parts 1523 move along the conus portion 1524b of col-lar part 1524, overcome the screen resilience of Compress Spring 1522 and be pressed into the direction, inner side of groove 1521.

Thus, ball parts 1523 are deviate from completely from the recess 1512b of the second change gear 512b, therefore the second change gear 512b and another switch the engagement releasing of power transmission shaft 1520.

(4) operation on the arrow S direction of sliding handle 540 (with reference to Figure 20) is proceeded, when another switching power transmission shaft 1520 continues to slide mobile to M direction:

Another switches power transmission shaft 1520 and continues to slide to M direction to move, thus groove 1521 continues the mobile movement and ball parts 1523 also slide of sliding.And, when ball parts 1523 move gradually to the position of the first change gear 512a, by the screen resilience of Compress Spring 1522, the gap of ball parts 1523 to the recess 1512a of the first change gear 512a is extruded (with reference in fig 23 with the ball parts 1523 that solid line represents).That is, being the first change gear 512a switches via ball parts 1523 and another state that power transmission shaft 1520 engages.

Thus, the transmission of the rotary driving force on Endrem axle 171, switches from the second change gear 512b to the first change gear 512a.

Be configured in present embodiment 3, col-lar part 1524 is configured between the first change gear 512a and the second change gear 512b, conus portion 1524a, 1524b that the both ends of within it all sides are formed contact with ball parts 1523, thus can prevent another from switching power transmission shaft 1520 rocking in glide direction (N direction or M direction).And be configured to, make the external diameter of ball parts 1523 larger than the width of the first change gear 512a and the second change gear 512b, the volume making ball parts 1523 enter the part of the recess 1512a of the first change gear 512a and the recess 1512b of the second change gear 512b increases, and reliably carries out switching the transmission of power transmission shaft 1520 to the first change gear 512a or the second change gear 512b from another.

And, be configured in present embodiment 3, ball parts 1523 are pushed to recess 1512a, 1512b by Compress Spring 1522, thus on Endrem axle 171, such as apply overload, become the first change gear 512a or the second change gear 512b when temporarily becoming lock-out state, another switches power transmission shaft 1520 and continues to rotate, therefore relative to recess 1512a or 1512b, groove 1521 offsets to rotation direction position, consequently, ball parts 1523 are pressed into the direction, inner side of groove 1521.And, the part at the Bu Han center of ball parts 1523 is only embedded in recess 1512a or 1512b, thus the shoulder of the oblique spherical surface of ball parts 1523 and the inner-diameter portion whose of the first change gear 512a near recess 1512a or 1512b or the second change gear 512b (i.e. the border of inner-diameter portion whose and recess) contacts and pushes, therefore ball parts 1523 are pressed into the direction, inner side of groove 1521.

Thus, the first change gear 512a or the second change gear 512b, switch the engagement releasing of power transmission shaft 1520 with another, ball parts 1523 play a role as overload clutch.That is, another switching power transmission shaft 1520 dallies, therefore, it is possible to prevent the breakage of the 3rd gear mechanism.

And, although in the above-described embodiment, the scope of the plantation spacing in the rows corresponding with " planting 1 (low speed) " and the overlapping formation of the range section of the plantation spacing in the rows corresponding with " planting 2 (at a high speed) " are illustrated, such as, but being not limited thereto, also can be that the scope of each plantation spacing in the rows does not have overlapping formation.

And, although in the above-described embodiment, the situation scope of 2 kinds of plantation spacing in the rows corresponding to 2 kinds of travel speeds of " plantation 1 (low speed) " and " plantation 2 (at a high speed) " being pre-stored within storage part 810 is illustrated, such as, but being not limited thereto, also can be the formation scope of the plantation spacing in the rows of more than 3 kinds corresponding for the travel speed with more than 3 kinds being pre-stored within storage part 810.

And, although in the above-described embodiment, the scope of plantation spacing in the rows that can set display simultaneously on display part 630 and the formation of upper and lower bound are illustrated, but are not limited thereto, such as, also can be the formation of any one party optionally showing the upper limit or lower limit.

And, although in the above-described embodiment, the scope of the plantation spacing in the rows that display part 630 can set is shown on viewing area, left side, and the formation that the value of the plantation spacing in the rows of actual set shows on right-hand part viewing area is illustrated, but be not limited thereto, also can be such as any one party of display of the display of scope of the plantation spacing in the rows that can set, the value of the plantation spacing in the rows of actual set, the formation that all viewing areas of display part 630 optionally show.

And, although in the above-described embodiment, the scope of the plantation spacing in the rows that display part 630 can set is shown on viewing area, left side, and the formation that the value of the plantation spacing in the rows of actual set shows on right-hand part viewing area is illustrated, but be not limited thereto, such as, also can be the display of scope of the plantation spacing in the rows that can set, formation that the value of the plantation spacing in the rows of actual set shows accumulative plantation radical further.Thereby, it is possible to carry out the management of planting radical.Further, the function resetted by the plantation radical of display is possessed, such as also can according to the formation of the plantation radical of each farmland measurement seedling.

And, although in the above-described embodiment, operator can not the formation of pushing force of adjusting tray pushing spring 925 be illustrated, but be not limited thereto, such as be configured to the fixed position of another square end 925b of pallet pushing spring 925 to be selectively arranged at multiple position, thus also can be that operator the weight of pallet 20 can regulate the formation of pushing force.

And, although in the above-described embodiment, even if to the leading section 923a of the first push plate 923 when carrying out longitudinal direction conveying to pallet 20, also can be illustrated with the formation of edge, the periphery 20a of certain pushing force pushing pallet 20, but be not limited thereto, such as when carrying out longitudinal direction conveying to pallet 20, also can be pushing force be zero formation.

Further, although in the above-described embodiment, the situation that the first push plate 923 is plate-shaped member is illustrated, is not limited thereto, also can be such as section configuration be circular bar-like member.Thus, not easy damaged pallet 20.

And, when the first push plate 923 for section configuration be circular bar-like member, also can be prevent on the surface of upper end edge portion 921a of guide plate 921 in the lateral shift corresponding with the leading section 923a that roughly L-shaped bends, the formation of the roughly depression of semi-circular shape when forming side-looking.By this formation, when by section configuration being edge, the periphery 20a of the leading section pushing pallet 20 of the first circular push plate, its edge, periphery 20a bends along the shape of this depression, therefore, it is possible to positively push pallet 20, reliably prevents the skew of pallet 20.

And, the surface that lateral shift prevents the upper end edge portion 921a of guide plate 921 forms the formation of the depression of roughly semi-circular shape, in the central authorities of this depression, when forming side-looking compared with the height of the edge of this depression the formation of the projection that the height of leading section is low.By this formation, when only being pushed edge, the periphery 20a of pallet 20 by the first push plate, this edge, periphery this projection of 20a hook, can reliably fixed tray 20.

Further, although in above-mentioned embodiment 1, use known allocation to stop the situation of clutch to be illustrated to as plantation clutch 420, be not limited thereto, such as, also can use the second plantation clutch of roll-type shown in Figure 24.Below, the second plantation clutch 1420 is described.Here, same-sign is marked to the formation identical with above-mentioned embodiment and the description thereof will be omitted.

Here, Figure 24 is the end view of the pattern for illustration of the second plantation clutch 1420.

As shown in figure 24, the second plantation clutch 1420 is from formation via 3 rollers 1422 output shaft 1423 transmission rotary driving force to the inside of the power shaft 1421 in outside.The output shaft 1423 of Figure 24 is corresponding with the power transmission shaft 421 of the plantation clutch 420 of above-mentioned embodiment 1.

As shown in figure 24, the inner circumferential shape of the section of power shaft 1421 and peripheral shape are toroidal.On the other hand, the peripheral shape of output shaft 1423, as shown in figure 24,3 limits that configure corresponding to the position of 3 rollers 1422 are line part 1423a, are each other by the shape that arc sections 1423b connects by these line parts 1423a.The gap 1424 existed between line part 1423a and the inner peripheral surface 1421a of power shaft 1421, narrow near the both ends of this line part 1423a and central portion during side-looking, and the diameter of both ends and roller 1422 is narrow, and wide compared with the diameter of roller 1422 near central portion.

The section configuration being configured at gap 1424 is movably circular roller 1422, exerted a force by spring (not shown), section configuration is the release cam spacer ring 1425 of circular ring-type, exert a force to arrow A direction (namely identical with the direction of rotation of power shaft 1421 and output shaft 1423 direction).

To 3 rollers 1422 of arrow A direction force, the square end portion 1423a1 to the both ends of line part 1423a pushes, thus 3 rollers 1422 contact with output shaft 1423 with power shaft 1421 simultaneously.Thus, the rotary driving force of power shaft 1421 is to output shaft 1423 transmission.

Therefore, under this drive state, power shaft 1421, output shaft 1423 and release cam spacer ring 1425 rotate integrally.

And, release cam spacer ring 1425, one end 460a of the first arm 460 illustrated by Fig. 4, limit the rotation on its A direction, then 3 rollers 1422 move to arrow A side in the opposite direction relative to output shaft 1423, the wider portion in the gap 1424 of roller 1422 between power shaft 1421 and output shaft 1423, roller 1422 is separated from the inner peripheral surface 1421a of the power shaft 1421 or line part 1423a of output shaft 1423, becomes non-drive state.

When becoming this non-drive state, be subject to the impact of inertia etc., when 3 rollers 1422 are to when excessively moving in the opposite direction with arrow A side, the reverse some rotations of output shaft 1423 wait and there is the possibility of the stopping instability of output shaft 1423.But, in configuration example shown in Figure 24, the block plate 1426 rotated integrally with output shaft 1423 is set, thus stops to 3 rollers 1422 with the movement in the opposite direction of arrow A side, prevent from excessively moving round about, be configured to prevent the stopping of output shaft 1423 unstable.

Further, although in the above-described embodiment, engine 12 and gearbox 4 etc. are illustrated by the formation that bonnet 109 covers.On the other hand, in Figure 25 (a), Figure 25 (b), the example of thermovent 109a is set at the rear portion of this bonnet 109.Figure 25 (a) is the stereogram of bonnet 109, and Figure 25 (b) is the stereogram of the bonnet 109 of Figure 25 (a) viewed from H direction.By the thermovent 109a shown in this figure, the outer gas that the air inlet 109b arranged from the front face at bonnet 109 enters, after cooling, rearward discharges from thermovent 109a engine 12 and gearbox 4 etc.

And, although in above-mentioned embodiment 1, to as shown in figure 15, configure between engine belt wheel 860 and gearbox belt wheel 865 hydraulic pump (hydraulic gear pump) 850 formation, namely side-looking time between engine output shaft and transmission input shaft, configure hydraulic pump 850 situation be illustrated, such as, but being not limited thereto, also can be the formation when side-looking at the front of engine belt wheel 860 (engine output shaft) configuration hydraulic gear pump and alternating current generator (charging machine) (omitting diagram).Thus, the maintenance of hydraulic gear pump or alternating current generator (charging machine) is easily carried out from body front.And, when this formation, the tension force that the hydraulic gear pump configured in the front of engine belt wheel 860 (i.e. engine output shaft) and the driving-belt hung between alternating current generator and engine belt wheel 860 apply to engine output shaft, is acted on round about to the tension force that engine output shaft applies by the first driving-belt 855 hung between engine belt wheel 860 and gearbox belt wheel 865 and configures.Thus, offset the tension force of the both sides of driving-belt relative to engine output shaft, therefore can not to the load of engine output shaft effect driving-belt.

And, although in above-mentioned embodiment 3, time chimeric with the recess 1512a of the first change gear 512a to ball parts 1523 and time chimeric with the recess 1512b of the second change gear 512b, in any one situation, the formation that the center of ball parts 1523 is positioned at inner side than the surface that another switches power transmission shaft 1520 is illustrated, such as, but being not limited to, also can be that the center of ball parts 1523 switches than another formation that surface of power transmission shaft 1520 is positioned at outside.

By this formation, the gap of more than half portion of the volume of ball parts 1523 (or major part) press-in recess 1512a or 1512b, when therefore such as acting on larger load on Endrem axle 171, ball parts 1523 can not be separated from recess 1512a or 1512b, therefore groove 1521 can not offset as rotation direction position relative to recess 1512a or 1512b, first change gear 512a or the second change gear 512b, switches the rotation synchronous axial system of power transmission shaft 1520 with another.

On the other hand, even if when this formation, the center of ball parts 1523 is not positioned at the formation of the side contrary with groove 1521 relative to conus portion 1524a, 1524b, another switch power transmission shaft 1520 to N direction, M direction slide the speed change of movement time, with conus portion 1524a, 1524b of col-lar part 1524, ball parts 1523 are pressed into the direction, inner side of groove 1521, therefore, it is possible to carry out the switching to the first change gear 512a or the second change gear 512b smoothly.Further, when this formation, ball parts 1523 can not be had an effect as overload clutch.

And, make the degree of depth of recess 1512a different with the degree of depth of recess 1512b (make the degree of depth of the depth ratio recess 1512b of recess 1512a dark), to make ball parts 1523 enter recess 1512a different with the volume of recess 1512b, thus can with the first change gear 512a and the second change gear 512b gearratio separately accordingly, suitable cut-out loading plays function as above-mentioned overload clutch.

Further, make the degree of depth of recess 1512a different with the degree of depth of recess 1512b, in recess 1512a and 1512b, be embedded in the center of ball parts 1523 at the recess of a side, but in the recess of the opposing party, do not embed the formation at the center of ball parts 1523.Thus, to the change gear corresponding with the recess of a side, ball parts 1523 do not play a role as overload clutch, but for the change gear corresponding with the recess of the opposing party, ball parts 1523 play a role as overload clutch.
