Make side-prominent backward power take-off outstanding from the back of main transmission box 12, by this power take-off power is input in the plantation transmission case 26.Transmission in the plantation transmission case 26 is described, as shown in Figure 8, the power shaft 193 of the fore-and-aft direction of one rotation is set at the axle identical with above-mentioned power take-off, passes through to the left and right the first axle 195 transmissions of direction of bevel- gear sett 194a, 194b from this power shaft 193.In addition, front at plantation transmission case 26, on power shaft 193, the overload clutch 196 that cuts off power by predetermined above load torque is set, because of mechanical lock (メ カ ロ Star Network) etc. when cultivation device 19 has been produced excessive workload, cut off power by overload clutch 196, prevent from comprising cultivation device 19 and plant transmission case 26 in the breakage of interior plantation transmission mechanism.At the first axle 195 the first drive sprocket 197 that rotates with these the first axle 195 one is set, from the first drive sprocket 197 by as the first ring body 198 of driving-chain to 199 transmissions of the first driven sprocket, and to the second axle 200 transmissions of the left and right directions of the axle that becomes the transmission upstream of this first driven sprocket 199 one rotation.On the second axle 200 and the first driven sprocket 199 about side's side (left side), about arrange three driving side gear 201a, 201b, 201c, these three driving side gear 201a, 201b, 201c rotate with the second axle 200 one.In addition, the pitch diameter that above-mentioned a plurality of driving side gear 201a, 201b, 201c are set as each other is different, and the number of teeth each other is different.

The 3rd axle 203 of the left and right directions that becomes jackshaft arrange with a plurality of driving side gear 201a, 201b, 201c in the independent slave end gear 202 of any engagement, by this slave end gear 202 is slided on the 3rd axle 203 to the left and right, thus become slave end gear 202 for three driving side gear 201a, 201b, 201c in any engagement and the structure changed.In addition, the 3rd axle 203 becomes the structure of rotating with slave end gear 202 one by being formed at the lip-deep spline 204 of this axle.

Slave end gear 202 slide through and slave end gear 202 interlock as the selection mechanism 205 of sliding axle horizontally slip carry out.Selection mechanism 205 possess with the linkage portion 206 of slave end gear 202 interlock and with these linkage portion 206 one sliding axle 207 of extending of direction to the left and right, the end of sliding axle 207 is outstanding from the side of left and right sides the opposing party's side (right side) of plantation transmission case 26, is fixed with conversion operations handle 208 in the end of sliding axle 207.Therefore, by the operator conversion operations handle 208 is operated to the left and right, selection mechanism 205 is moved and the position, the left and right sides of conversion linkage portion 206 to the left and right, and conversion is to the gearratio of the 3rd axle 203.The transformational structure of the gearratio that is undertaken by this selection mechanism 205 becomes change cultivation device 19 changes the plantation spacing in the rows with respect to the responsiveness of travel speed spacing in the rows speed change gear.Sliding axle 207 is configured in the top of the 3rd axle 203 and the front end of ratio the 3rd axle 203 leans on rear side, and the selection mechanism 205 that comprises linkage portion 206 is configured in the upside of the 3rd axle 203 and leans on rear side than the 3rd axle 203.

The end of side's side (left side) about the 3rd axle 203 arranges the second drive sprocket 209 with the rotation of the 3rd axle 203 one, from the second drive sprocket 209 by as the second annular solid 210 of driving-chain to 211 transmissions of the second driven sprocket.This second driven sprocket 211 is the 4th axles of left and right directions, and be that driving shaft (swing driving shaft) at the axle that becomes the transmission downstream is the structure of oscillating cam driving shaft 88 idle running, with the driving side corpus unguis 213 one rotation of the driving body that is arranged on the conduct plantation clutch 212 on the oscillating cam driving shaft 88.Plantation clutch 212 is that the assigned position that stops at predetermined rotatable phase (assigned position) when cutting off transmission stops clutch, and the plantation utensil 28 of cultivation device 19 is stopped in the position that surpasses the top dead centre on the track 17 that moves and descend a little.Plantation clutch 212 is configured in left and right sides the opposing party's side (right side) of the second driven sprocket 211, become slave end corpus unguis 214 and the rotation of oscillating cam driving shaft 88 one and to the structure of axial move left and right, above-mentioned slave end corpus unguis 214 as with the driven member of driving side corpus unguis 213 engagements, thereby carry out to connection and the cut-out of the transmission of oscillating cam driving shaft 88.In addition, be respectively equipped with intermeshing four cooperation pawl 213a and four cooperation pawl 214a at driving side corpus unguis 213 and slave end corpus unguis 214.

Namely, as shown in Figure 9, slave end corpus unguis 214 in the axial direction move left and right be assemblied in freely on the oscillating cam driving shaft 88.And, the axis hole 214 of the central portion that is arranged at slave end corpus unguis 214 ' in, the keyway 214b that connects vertically is set, become this keyway 214b structure chimeric with being arranged on key 88a on the oscillating cam driving shaft 88.Therefore, become slave end corpus unguis 214 and the rotation of oscillating cam driving shaft 88 one, and on oscillating cam driving shaft 88 the move left and right structure of assembling freely vertically.

And, on the outer peripheral face of the slave end corpus unguis 214 of planting clutch 212, form operation of cam 215, this operation of cam 215 makes slave end corpus unguis 214 leave and cut off from driving side corpus unguis 213 and plants clutch 212, and the plantation utensil 28 of cultivation device 19 is stopped in the afore mentioned rules position.This operation of cam 215 is by inclined plane 215a and stop to consist of with contact-making surface 215b, this inclined plane 215a is by contacting the operative pin 216a as contact described later and making oscillating cam driving shaft 88 to arrow F direction rotation, thereby slave end corpus unguis 214 is moved to the direction of leaving driving side corpus unguis 213, disconnect both connections and cut off plantation clutch 212; This stops to make slave end corpus unguis 214 leave driving side corpus unguis 213 with contact-making surface 215b, in plantation after clutch 212 is cut off, and operating of contacts pin 216a and the plantation utensil 28 of cultivation device 19 is stopped in the afore mentioned rules position.

And above-mentioned slave end corpus unguis 214 leaves driving side corpus unguis 213 and moment that plantation clutch 212 disconnects is come moment just over the position of the lifting position of its track 17 for plantation utensil 28 by lifting link mechanism 29.Therefore, plantation clutch 212 utilizes the inertia force that the plantation utensil 28 just over lifting position will move downward and disconnects reliably.And, after plantation clutch 212 disconnects reliably, plantation utensil 28 inertia force that will move downward diminishes gradually by the active force of the plantation clutch spring 217 of the following Compress Spring of conduct of inclined plane 215a that operative pin 216a is contacted and 214 reinforcings of slave end corpus unguis, operative pin 216a with stop to contact and making with contact-making surface 215b planting utensil 28 and suitably stop at assigned position.

In addition, as shown in figure 10, the plantation clutch operating mechanism 216 that is provided with the operative pin 216a relative with aforesaid operations cam 215 at front end is outstanding to operation of cam 215 sides (front side), operative pin 216a contacts with operation of cam 215, thereby becomes the structure of the transmission of cutting off as mentioned above plantation clutch 212.Otherwise, as shown in figure 11, if returning with operation of cam 215 opposition sides (rear side), plantation clutch operating mechanism 216 leaves operation of cam 215, then driving side corpus unguis 213 and slave end corpus unguis 214 utilize slave end corpus unguis 214 are meshed to the plantation clutch spring 217 of driving side corpus unguis 213 sides (left side) pushing, and plantation clutch 212 becomes drive state.

At this moment, on the slave end corpus unguis 214, arrange than operation of cam 215 positions more to the outstanding circular-arc protuberance 215c of peripheral direction at the position that stops with contact-making surface 215b that is provided with operation of cam 215 terminal parts.And, circular-arc protuberance 215c will stop the rear corners of mobile direction (direction that plantation clutch 212 enters) to be pruned obliquely by 217 reinforcings of plantation clutch spring with the slave end corpus unguis 214 of contact-making surface 215b, form contact lead-in chamfered 215d.

Therefore, in the situation of the transmission that adds plantation clutch 212, operative pin 216a is moved to the direction of leaving operation of cam 215, operative pin 216a is when stopping contact lead-in chamfered 215d with the circular-arc protuberance 215c of contact-making surface 215b and moved, operative pin 216a is in order to slide at contact lead-in chamfered 215d and to move, slave end corpus unguis 214 is by 217 reinforcings of plantation clutch spring, produce slave end corpus unguis 214 forcibly with the effect of driving side corpus unguis 213 engagements, plantation clutch 212 reliably and promptly becomes the state of beginning transmission.Thereby, operative pin 216a leaves and stops to use contact-making surface 215b, the driving that the beginning transmission of the moment of the decline of the plantation utensil 28 that lifting link mechanism 29 carries out and plantation clutch 212 forms is constantly almost identical, and plantation utensil 28 is by lifting link mechanism 29 driven action the suitably.

In addition, be meshed with driving side corpus unguis 213 and plant under the state of clutch 212 beginning transmissions at slave end corpus unguis 214, operative pin 216a is positioned at the relative position of the side 215e with slave end corpus unguis 214 opposition sides of circular-arc protuberance 215c, and operative pin 216a can not hinder the rotation of slave end corpus unguis 214.

And, beginning to descend by lifting link mechanism 29 at plantation utensil 28, ridge U upper surface charged into by plantation utensil 28 and with during the seedling plantation is in the U of ridge, circular-arc protuberance 215c is positioned at the position relative with operative pin 216a.Therefore, even charge into ridge U upper surface and the plantation load when seedling plantation is on the U of ridge and oscillating cam driving shaft 88 applied the driving load by plantation utensil 28, operative pin 216a also is positioned at the position relative with the side 215e of circular-arc protuberance 215c, therefore stop operative pin 216a to contact with the side 215e of circular-arc protuberance 215c and make slave end corpus unguis 214 leave driving side corpus unguis 213, can prevent that the transmission of planting clutch 212 is cut off, can carry out the transplanting operation of suitable seedling.

In addition, plantation clutch operating mechanism 216 is configured in the rear of oscillating cam driving shaft 88 and leans on rear side than oscillating cam driving shaft 88.And, if the operator will be arranged on towards the body rear plantation clutch lever 161 on the centre position, the left and right sides of control crank 16 to the operation of plantation clutch cutting direction, the operative pin 216a that then plants clutch operating mechanism 216 is outstanding to operation of cam 215 sides (front side), operative pin 216a contacts with operation of cam 215, thereby cuts off as mentioned above the transmission of plantation clutch 212.Otherwise, if the operator will plant clutch lever 161 and connect direction operation to the plantation clutch, the operative pin 216a that then plants clutch operating mechanism 216 returns and operation of cam 215 opposition sides (rear side), leave operation of cam 215, driving side corpus unguis 213 and slave end corpus unguis 214 utilize plantation clutch spring 217 and mesh, and plantation clutch 212 becomes drive state.

The end of side's side (left side) is outstanding from plantation transmission case 26 about oscillating cam driving shaft 88, perforation be fixed on plantation transmission case 26 about in the cultivation device driving box 27 of side of side's side (left side), and the side of side's side (left side) is outstanding from about the cultivation device driving box 27.As shown in Figure 7, in cultivation device driving box 27, the 3rd drive sprocket 218 with the rotation of oscillating cam driving shaft 88 one is set, from the 3rd drive sprocket 218 by as the 3rd annular solid (transmission annular solid) 107 of driving-chain to 220 transmissions of the 3rd driven sprocket, the 3rd driven sprocket 220 rotates with crank arm driving shaft 89 one described later.In addition, crank arm driving shaft 89 is with the rear of the level configurations identical with oscillating cam driving shaft 88 at oscillating cam driving shaft 88.In addition, above the 3rd annular solid 107, arrange and to contact with the 3rd annular solid 107 and give the leaf spring 221 of the 3rd annular solid 107 tension force.

On the other hand, end in the left and right sides of oscillating cam driving shaft 88 the opposing party's side (right side), bevel- gear sett 221a, 221b that the supply unit transmission is used are set, become the bevel-gear sett 221a, the 221b that use by the supply unit transmission and to the structure of the supply unit that protrudes from plantation transmission case 26 rear sides with power take-off 222 transmissions.That seedling supply unit 31 is by driving the structure of rotation with the transmission of power take-off 222 from supply unit.

If the configuration structure to the power transmission shaft in the plantation transmission case 26 describes, then as shown in Figure 6, the second axle 200 is configured in than the first axle 195 by rear side and top side, the 3rd axle 203 is configured in the rear (with the position of the second axle 200 roughly the same height) of the second axle 200, the 4th axle (oscillating cam driving shaft) 88 is configured in the top (front and back position roughly the same with the 3rd axle 203) of the 3rd axle 203.And, plantation transmission case 26 between the second axle 200 and the 4th axle 88 and the front side upper surface of the oblique front upper side of the 3rd axle 203 and plantation transmission case 26 form recess 223.

And, the body cover 224 of the top of covering engine 11 and main transmission box 12 is set, and is configured to make the rear portion 224a of this body cover 224 to charge into the recess 223 of planting transmission case 26.On body cover 224, be formed on plantation transmission case 26 about side's side (left side) and than the recess 223 of plantation transmission case 26 by the extension 224b that rear side prolongs, this extension 224b is configured in the top of the front portion (front swing arm 80 described later and left back swing arm 81) of lifting link mechanism 29.

Secondly, based on Figure 12 and Figure 13, illustrate when cutting off transmission what the rotatable phase (assigned position) of being scheduled to stopped stopping other examples of the plantation clutch 212 of clutch as assigned position.

Figure 12 represents the amplification plan view of plantation clutch of other examples of present embodiment, and Figure 13 represents the major part amplification plan view for the effect of this plantation clutch of explanation.

Left and right sides the opposing party's side (right side) that plantation clutch 212 shown in this embodiment and precedent similarly are configured in the second driven sprocket 211, become and the slave end corpus unguis 214 of driving side corpus unguis 213 engagement and the rotation of oscillating cam driving shaft 88 one and the structure of move left and right in the axial direction, carry out to connection and the cut-out of the transmission of oscillating cam driving shaft 88.In addition, be respectively equipped with intermeshing four cooperation pawl 213a and four cooperation pawl 214a at driving side corpus unguis 213 and slave end corpus unguis 214.

Namely, slave end corpus unguis 214 in the axial direction move left and right be assemblied in freely on the oscillating cam driving shaft 88.And, the axis hole 214 of the central portion that is arranged at slave end corpus unguis 214 ' in, the keyway 214b that connects vertically is set, become this keyway 214b structure chimeric with being arranged on key 88a on the oscillating cam driving shaft 88.Therefore, become slave end corpus unguis 214 and the rotation of oscillating cam driving shaft 88 one, and on oscillating cam driving shaft 88 the move left and right structure of assembling freely vertically.

And, on the outer peripheral face of the slave end corpus unguis 214 of planting clutch 212, form operation of cam 215, this operation of cam 215 makes slave end corpus unguis 214 leave and cut off from driving side corpus unguis 213 and plants clutch 212, and the plantation utensil 28 of cultivation device 19 is stopped in the afore mentioned rules position.This operation of cam 215 is by inclined plane 215a and stop to consist of with contact-making surface 215b, this inclined plane 215a is by contacting operative pin 216a described later and making oscillating cam driving shaft 88 to arrow F direction rotation, thereby slave end corpus unguis 214 is moved to the direction of leaving driving side corpus unguis 213, disconnect both connections and cut off plantation clutch 212; This stops to make slave end corpus unguis 214 leave driving side corpus unguis 213 with contact-making surface 215b, in plantation after clutch 212 is cut off, and operating of contacts pin 216a and the plantation utensil 28 of cultivation device 19 is stopped in the afore mentioned rules position.

And above-mentioned slave end corpus unguis 214 leaves driving side corpus unguis 213 and moment that plantation clutch 212 disconnects is come moment just over the position of the lifting position of its track 17 for plantation utensil 28 by lifting link mechanism 29.Therefore, plantation clutch 212 utilizes the inertia force that the plantation utensil 28 just over lifting position will move downward and disconnects reliably.And, after plantation clutch 212 disconnects reliably, plantation utensil 28 inertia force that will move downward diminishes gradually by the active force of the following plantation clutch spring 217 of inclined plane 215a that operative pin 216a is contacted and 214 reinforcings of slave end corpus unguis, operative pin 216a with stop to contact and making with contact-making surface 215b planting utensil 28 and suitably stop at assigned position.

In this embodiment, be to adopt following structure with the difference of above-described embodiment: on slave end corpus unguis 214, be provided with the fixedly engagement dog 214c of usefulness of rotation with a side left and right sides opposition side that is provided with engaged claw 214a, at plantation transmission case 26 fixation side engagement dog 26a is set, this fixation side engagement dog 26a cooperates with this engagement dog 214c and makes slave end corpus unguis 214 stop at the precalculated position.

Namely adopt following structure: aforesaid operations pin 216a with stop with contact-making surface 215b contact and make the plantation utensil 28 when assigned position stops, slave end corpus unguis 214 moves to the arrow B direction, the fixation side engagement dog 26a engagement of the plantation transmission case 26 of this engagement dog 214c and fixation side, thus plantation utensil 28 reliably and suitably stops at desired location.

And, if will plant clutch lever 161 to the operation of plantation clutch cutting direction, the operative pin 216a that then plants clutch operating mechanism 216 charges into operation of cam 215 sides (front side), and operative pin 216a contacts with operation of cam 215, thereby cuts off as mentioned above the transmission of plantation clutch 212.Otherwise, connect direction operation if will plant clutch lever 161 to the plantation clutch, the operative pin 216a that then plants clutch operating mechanism 216 returns with operation of cam 215 opposition sides (rear side) and leaves operation of cam 215, driving side corpus unguis 213 and slave end corpus unguis 214 mesh by plantation clutch spring 217, and plantation clutch 212 becomes drive state.

In addition, the engaged claw 214a of slave end corpus unguis 214 forms outstanding that higher high engaged claw 214a-1 to get lower low this two-stage of engaged claw 214a-2 with giving prominence to.Therefore, connect direction operation if will plant clutch lever 161 to the plantation clutch, the operative pin 216a that then plants clutch operating mechanism 216 returns with operation of cam 215 opposition sides (rear side) and leaves operation of cam 215, to 217 reinforcings of plantation clutch spring, slave end corpus unguis 214 is mobile to driving side corpus unguis 213 sides (arrow C direction), the high engaged claw 214a-1 that gives prominence to highlyer of slave end corpus unguis 214 embeds between the engaged claw 213a of driving side corpus unguis 213, keep the state of fixation side engagement dog 26a engagement of the plantation transmission case 26 of the engagement dog 214c of slave end corpus unguis 214 and fixation side, thereby plantation utensil 28 is maintained the state that stops at desired location.Therefore, in the time will planting clutch lever 161 to plantation clutch connection direction operation, can avoid the state of affairs that plantation utensil 28 moves with deadweight before plantation clutch 212 becomes drive state.

And, if slave end corpus unguis 214 is outstanding that higher high engaged claw 214a-1 embeds between the engaged claw 213a of driving side corpus unguis 213, then the engagement of the fixation side of the plantation transmission case 26 of the engagement dog 214c of slave end corpus unguis 214 and fixation side engagement dog 26a is thrown off, plantation utensil 28 becomes movable state, then, if slave end corpus unguis 214 is outstanding that lower low engaged claw 214a-2 also embeds between the engaged claw 213a of driving side corpus unguis 213, then the engaged claw 214a of the engaged claw 213a of driving side corpus unguis 213 and slave end corpus unguis 214 meshes reliably, and plantation clutch 212 becomes drive state.

Therefore, if slave end corpus unguis 214 is outstanding that higher high engaged claw 214a-1 embeds between the engaged claw 213a of driving side corpus unguis 213, then the cooperation of the fixation side of the plantation transmission case 26 of the engagement dog 214c of slave end corpus unguis 214 and fixation side engagement dog 26a is thrown off, plantation utensil 28 becomes movable state, then, if slave end corpus unguis 214 is outstanding that lower low engaged claw 214a-2 also embeds between the engaged claw 213a of driving side corpus unguis 213, then the engaged claw 214a of the engaged claw 213a of driving side corpus unguis 213 and slave end corpus unguis 214 meshes reliably, plantation clutch 212 becomes drive state, thus, can prevent the engagement dog 214c of slave end corpus unguis 214 and fixation side plantation transmission case 26 the 26a engagement of fixation side engagement dog and make the engaged claw 214a engagement of engaged claw 213a and the slave end corpus unguis 214 of driving side corpus unguis 213 with stationary state, thereby plantation clutch 212 becomes drive state, can prevent that thus transmission mechanism is damaged.

Secondly, other examples of the speed-changing operation device of spacing in the rows speed change gear described.

Vertical view is launched in the major part cross section of Figure 14 plantation transmission case that to be expression describe the effect of the spacing in the rows speed change of other examples of present embodiment and secondary variable speed operation.

In above-mentioned example, represented by conversion operations handle 208 is operated to the left and right, selection mechanism 205 to the left and right mobile and conversion linkage portion 206 position, the left and right sides and slave end gear 202 is slided on the 3rd axle 203 to the left and right, thus slave end gear 202 for three driving side gear 201a, 201b, any engagement among the 201c and change to carry out the example of spacing in the rows variable speed operation, but in the example shown in Figure 14, adopt following structure: conversion spacing in the rows variable speed operation and the travel speed of main transmission box 12 and the secondary variable speed operation of operating speed are undertaken by an action bars 280.

Namely, will be located near control crank 16 operating handle 280a and be arranged on the rear portion, leading section is supported in set through hole 281a and the rotation of leading section that connects L font support chip 281 freely, and these L font support chip 281 usefulness bolts are fixedly installed on the right side wall of main transmission box 12.In addition, for action bars 280 can be operated at left and right directions, this through hole 281a is slightly larger than the diameter of action bars 280 front ends.

And, in the front portion of action bars 280 and the position, dead astern of L font support chip 281, be welded and fixed the base portion of the secondary variable speed operation arm 282 that extend to arrange towards the top, the upper end of this pair variable speed operation arm 282 is attached at from the outstanding secondary variable speed operation bar 283 that arranges of the right side wall of main transmission box 12.Therefore, carry out rotating operation if stand in the operating handle 280a that near the control crank 16 operators hold action bars 280, then the top of secondary variable speed operation arm 282 is by to arrow D-E direction operation, secondary variable speed operation bar 283 with it interlock is carried out the push-and-pull operation, when the operating handle 280a that makes action bars 280 is in level, secondary speed change speed change is travel speed (at a high speed), and when the operating handle 280a that makes action bars 280 made progress and be vertical, secondary speed change speed change was operating speed (low speed).

By 88 rotations of oscillating cam driving shaft, the wobble drive cam 84 that is fixed on the oscillating cam driving shaft 88 rotates with oscillating cam driving shaft 88, and left back swing arm 81 and front swing arm 80 are by swinging forwards, backwards with the live-rollers 87 of wobble drive cam 84 butts.At this moment, also swing forwards, backwards with left back swing arm 81 with the right back swing arm 99 that left back swing arm 81 links by upper rear axle 90.

On the other hand, by 89 rotations of crank arm driving shaft, the crank arm 85 that is fixed on the crank arm driving shaft 89 rotates with crank arm driving shaft 89, and lower-left arm 83 and bottom right arm 97 swing up and down by armite 86 and left and right sides connecting rod 98, and upper arm 82 also swings up and down with lower-left arm 83.

Therefore, front swing arm 80, left back swing arm 81 and right back swing arm 99 all are parallel linkage mechanisms with upper arm 82, lower-left arm 83 and bottom right arm 97, therefore plant utensil 28 and keep posture towards vertical direction, move in the mode of describing to plant track 17 its lower end, can be linked into rice shoots in the plantation utensil 28 with suitable posture plantation in the U of ridge.

In addition, as shown in figure 19, the cultivation device 19 of present embodiment, about plantation utensil 28, axle 95 is on the front on than the rotation that links upper arm 82 with the position configuration of rotation lower shaft 96 that links lower-left arm 83.

Be configured in than rotating axle 95 on the front by rotating lower shaft 96, thereby the interval of upper arm 82 and lower-left arm 83 narrows down in the time of can suppressing to plant utensil 28 and descend.

According to this structure, in the time of near plantation utensil 28 is positioned at lower dead center, can keep upper arm 82 wider with the interval of lower-left arm 83, therefore under the plantation state, can not rock, can carry out stable plantation.

Set as follows the shape of wobble drive cam 84 and wobble drive cam 84 and be fixed on mode on the oscillating cam driving shaft 88, this mode is: in position from seedling to plantation utensil 28 that supply with, the variation of diameter of namely planting the wobble drive cam 84 of the position that near the wobble drive cam 84 of utensil 28 when being positioned at the top dead centre of track 17 of action contact with live-rollers 87 diminishes, in addition, in the position of planting seedling, namely plant the position that near the wobble drive cam 84 of utensil 28 when being positioned at the lower dead center contact with live-rollers 87 wobble drive cam 84 diameter the variation change greatly.

According to this structure, the translational speed of the front end of plantation utensil 28 is become, during than the plantation seedling, very slow when supplying with seedling.

In addition, in top dead centre and lower dead center, crank arm 85 and armite 86 are in vertical direction with the overlapping position of linearity, and, become the structure parallel with front swing arm 80, left back swing arm 81 and right back swing arm 99.Therefore, set as follows the direction of crank arm 85: when supplying with seedling to plantation utensil 28, plant utensil 28 when being positioned near the top dead centre, and the position of plantation seedling, namely to plant the armite 86 that near the rotation of the crank arm 85 of utensil 28 when being positioned at the lower dead center causes little in the variation of the position of above-below direction.According to this structure, constitute when the plantation action, front end by plantation utensil 28 moves in the mode of the track 17 of describing ring-type, and near the translational speed of the plantation utensil 28 of (supplying with the position of seedling) top dead centre is than slow in the translational speed of lower dead center (position of plantation seedling).Therefore, can supply to plantation utensil 28 with transplanting object more reliably.

In addition, when the front end of plantation utensil 28 is positioned at the position of plantation transplanting object, crank arm 85 and armite 86 are overlapping with linearity, thus moving up and down of carrying out of crank arm 85 and armite 86 be formed slopely move up and down unanimously, can accelerate to plant the action of utensil 28.In addition, when the front end of plantation utensil 28 is positioned at the position of plantation transplanting object, crank arm 85 is parallel to each other with front swing arm 80, left back swing arm 81 and right back swing arm 99, therefore swing arm 80, left back swing arm 81 and moving up and down of right back swing arm 99 tail off before, can by moving up and down that crank arm 85 and armite 86 carry out, make plantation utensil 28 more mobile.

And adopt following structure: the width by the track 17 described of front end of plantation utensil 28 front and back when the plantation is maximum, and namely than the center of the width that moves up and down of plantation utensil 28 section on the lower, the width of front and back be maximum.In the position on the lower, width center that moves up and down of front end than plantation utensil 28, the front and back width of quiet track 17 be maximum, so the moving track of tree-remover when travelling become the track of linearity ground about carrying out, and can plant the transplanting object attractive in appearancely.

In addition, utilize a crank arm 85 to make the link mechanism action of the parallel shape that is consisted of by upper arm 82, lower-left arm 83 and bottom right arm 97 of cultivation device 19.Owing to driving with the crank arm 85 of an axle, so can suppress the plantation undesirable condition that the gap of transmission system causes.

In addition, by wobble drive cam 84 above-mentioned lifting link mechanism 29 is moved forward and backward.Owing to being the structure of using wobble drive cam 84, therefore can freely set the front and back width of the track 17 that the front end of plantation utensil 28 describes.

In addition, owing to will be configured in the live-rollers 87 of wobble drive cam 84 butts than the middle position of the length direction of left back swing arm 81 near the position of upper rear axle 90, namely on the position of the oscillating cam driving shaft 88 of close fulcrum as front swing arm 80, therefore the distance with the fulcrum of wobble drive cam 84 can be shortened, wobble drive cam 84 can be dwindled.Owing to can dwindle wobble drive cam 84, therefore can realize the miniaturization of cultivation device 19.

In addition, the track that becomes quiet track 17 that the front end of plantation utensil 28 is described becomes toroidal near lower dead center, therefore the moving track that travels of having added cigarette seeding transplant machine 10 becomes linearity ground and carries out track up and down near lower dead center, can ground attractive in appearance bed out young plants etc. the transplanting object.Have, the scope that the track 17 that the front end of plantation utensil 28 is described is adjusted in planting depth is that toroidal is comparatively desirable again.Be the quiet track of toroidal by making the plantation scope of utensil 28 in charging into soil, thereby can reduce to plant the hole.

In addition, the track 17 described of front end by making plantation utensil 28 is in the shape that diminishes for the front and back width than the top side of planting depth place, thereby to the amount of movement of front side, the front end of plantation utensil 28 can not be suspended to the rice shoot of having planted etc. in the time of can strengthening plantation utensil 28 and rise.

In addition, since utilize the left back swing arms 81 of 167 pairs of extension springs to the power of lifting to oblique front upper place, therefore can prevent that the responsiveness that plantation utensil 28 is sharply fallen the plantation utensil 28 that causes on track 17 because of the deadweight of plantation utensil 28 is improper when plantation utensil 28 descends to the plantation position.In addition, the auxiliary plantation of the deadweight utensil 28 of the above-mentioned power of the lifting opposing plantation utensil 28 that extension spring 167 forms rises from lower dead center, and plantation utensil 28 is stably moved.

In addition, by crank arm 85 is rotated counterclockwise among the Figure 18 that observes from right side side, crank arm 85 to opposite spin, therefore easily makes near the translational speed of plantation utensil 28 top dead centre of track 17 slack-off with respect to the ring-type track 17 of planting utensil 28 actions.By making near the translational speed of plantation utensil 28 top dead centre slack-off, can more reliably seedling be supplied with to plantation utensil 28.

Near lower dead center, front swing arm 80, left back swing arm 81 and in the past direction rear action of right back swing arm 99, but the rotation connection shaft 106 of the front end of crank arm 85 forwards rotates from the rear.Move to ground because front swing arm 80, left back swing arm 81 and right back swing arm 99 and crank arm 85 are relative, therefore can make the speed that moves up and down of plantation utensil 28 slack-off, even the spacing in the rows of plantation changes, the variation of moving track in having added the soil that travels of body of plantation utensil 28 front ends is also little.

In addition, near lower dead center, since crank arm 85 and armite 86 in the vertical direction or close on the direction of vertical direction point-blank, crank arm 85 carries out move up and down and armite 86 be formed slopely move up and down unanimously, so can accelerate to plant the rate of climb of utensil 28.

Have again, near lower dead center, front swing arm 80, left back swing arm 81 and right back swing arm 99 are parallel with crank arm 85 and armite 86, thereby front swing arm 80, left back swing arm 81 and moving up and down of right back swing arm 99 tail off, by moving up and down that crank arm 85 and armite 86 carry out, plantation utensil 28 is more promptly risen.

Figure 24 is the figure of the allocation position of each driving shaft in the explanation cultivation device driving box 27, the figure that expression is observed from the left side of body.

As shown in figure 24, in the cultivation device 19 of present embodiment, oscillating cam driving shaft 88 and crank arm driving shaft 89 are configured on the position of roughly the same height.And, about connect cultivation device driving box 27 upper rear axle 90 be configured in than on the position on the lower of straight line each other, center that links oscillating cam driving shaft 88 and crank arm driving shaft 89.

27 driving forces of transmitting are passed to oscillating cam driving shaft 88 from plantation transmission case 26 to the cultivation device driving box.And in cultivation device driving box 27, by driving-chain 107, the driving force of oscillating cam driving shaft 88 also is delivered to crank arm driving shaft 89.

Driving-chain 107 centers on the axle rotation on every side of rear axle 90 in cultivation device driving box 27, but because upper rear axle 90 is configured in than on the position on the lower of straight line each other, center that links oscillating cam driving shaft 88 and crank arm driving shaft 89, even therefore driving-chain 107 relaxes and also can not contact with upper rear axle 90, driving force stably can be transmitted to crank arm driving shaft 89.In addition, according to this configuration, can configure compactly oscillating cam driving shaft 88, crank arm driving shaft 89 and upper rear axle 90.

Secondly, describe being used for opening and closing switching mechanism and the action thereof of planting utensil 28.

On axle 95 in the rotation of an end (rear end) that is arranged at upper arm 82, rotate the auxiliary 104 of the on-off action be provided for freely planting utensil 28.In addition, on the upper axle 92 of the other end that is arranged at upper arm 82 (front end), rotate switching arm 101 is set freely, utilize connecting rod 103 to link and open and close arm 101 and auxiliarys 104.In addition, at auxiliary 104 pin 105 is set.

In addition, be formed with the left side long slot bore 168 of the other end part of the cantilever lever section 63 that links cantilever 50 on the top of left side cantilever web 66.

Such as Figure 40 and shown in Figure 41, at an end of hydraulic stem 55, being provided with link pillar connecting axle 75 with the rectangular direction of the length direction of hydraulic stem 55, at the other end, be formed with the rotation post connect apertures 76 that links with rotation post 56.

As shown in figure 44, be inserted in the cylindrical portion of hydraulic stem linking part 62 by linking pillar connecting axle 75, link thereby hydraulic stem 55 can link pillar 51 with cantilever rotationally.

In addition, in Figure 44, omitted the record of the shaft portion of cantilever 50 and the link pillar circular shaft part 61 related with cantilever 50.

At the shaft portion of the bending that links pillar circular shaft part 61, be that the side is observed and the shaft portion that links 60 one-tenths V-shapes of pillar board, the cantilever shaft sleeve part 64 of insertion cantilever 50, cantilever 50 can endwisely slipping at link pillar circular shaft part 61.In addition, the left side long slot bore 168 of the both ends of the cantilever lever section 63 of cantilever 50 and left side earthing position detection bodies 36 and the right side long slot bore of right side earthing position detection bodies 37 173 link, and end separately can be in these long slot bores 168,173 interior movements.

The the second grounding body turning cylinder 52 that extends to the left and right directions of body is fixed on the left side grounding body support bar 54, in addition, the earth's axis is supported on the right side grounding body support bar 59 shaft portion that becomes the turning cylinder that links pillar circular shaft part 61 rotating freely with the coaxial position of the second grounding body turning cylinder 52, and left side earthing position detection bodies 36, right side earthing position detection bodies 37 and cantilever link pillar 51 and rotate centered by left and right directions coaxial.

Rotation post 56 freely rotates centered by being mounted to be arranged on rotation post axle 58 on the main frame 22.With regard to hydraulic stem 55, the link pillar connecting axle 75 that arranges at one end links with the hydraulic stem linking part 62 that cantilever links pillar 51, and the rotation post connect apertures 76 by being formed at the other end links with an end of rotation post 56.

Have, the other end of rotation post 56 and connecting rod 57 link again, and the other end of connecting rod 57 and hydraulic switch valve section 24 link.In addition, the intermediate linking part that links by the formation such as hydraulic stem 55, rotation post 56 and connecting rod 57 and hydraulic switch valve section 24.

By moving up and down of connecting rod 57, hydraulic lifting cylinder 23 moves with switching valve by means of the elevating control that is equipped with in the hydraulic switch valve section 24,14 liftings of left and right sides trailing wheel.

Secondly, the action that the height with body is controlled to be the mechanism of certain altitude describes.When the plantation operation of carrying out rice shoot, if ridge U upper surface near body, then left side earth plate 65 and right side earth plate 70 is lifted along ridge U upper surface, if ridge U upper surface away from body, then left side earth plate 65 and right side earth plate 70 descend along ridge U upper surface.

Here, near body, the state that left side earth plate 65 and right side earth plate 70 are lifted describes about ridge U upper surface.

In Figure 35, if left side earth plate 65 and right side earth plate 70 are lifted, then left side earthing position detection bodies 36 and right side earthing position detection bodies 37 are to rotate to counter clockwise direction at the second coaxial on left and right directions grounding body turning cylinder 52 and centered by linking pillar circular shaft part 61.

If left side earthing position detection bodies 36 and right side earthing position detection bodies 37 are to counterclockwise rotating, the cantilever lever section 63 that then two ends is cooperated with left side long slot bore 168 and right side long slot bore 173 applies to the power in body the place ahead, by cantilever 50 is applied to the power in body the place ahead, thereby the link pillar circular shaft part 61 that connects cantilever shaft sleeve part 64 is applied to the power in body the place ahead, and cantilever links pillar 51 and rotates to counter clockwise direction centered by being configured in the link pillar circular shaft part 61 on the left and right directions.

If cantilever links pillar 51 to counterclockwise rotating, then apply the power that hydraulic stem 55 is moved to body the place ahead, the rotation post 56 that links with the other end of hydraulic stem 55 rotates to clockwise direction centered by rotation post axle 58.If rotation post 56 rotates to clockwise direction, the connecting rod 57 that then links with the other end of rotation post 56 is moved upward.

If connecting rod 57 is moved upward, the hydraulic switch valve section 24 that then links with the other end of connecting rod 57 makes hydraulic lifting cylinder 23 actions by elevating control with switching valve, thereby left and right sides trailing wheel 14 descends.

Descend by left and right sides trailing wheel 14, body rises with respect to ridge U upper surface, the distance of body and ridge U upper surface can be remained certain distance.

When the plantation operation of carrying out rice shoot, in the situation that ridge U upper surface is away from body, left side earth plate 65 and right side earth plate 70 descend along ridge U upper surface, in Figure 35, left side earthing position detection bodies 36 and right side earthing position detection bodies 37 are rotated to clockwise direction, move on the contrary near the above-mentioned situation of body with ridge U upper surface.Namely, this occasion, connecting rod 57 is mobile downwards, and hydraulic switch valve section 24 makes hydraulic lifting cylinder 23 actions by elevating control with switching valve, and left and right sides trailing wheel 14 is risen.Namely, in this case, body descends with respect to ridge U upper surface, and the distance of body and ridge U upper surface is retained as certain distance.

By this control, during near body or away from body, the distance of body and ridge U upper surface all remains certain distance, so the plantation of rice shoot can not crossed dark or excessively shallow at ridge U upper surface.

In addition, left side grounding body support bar 54 and right side grounding body support bar 59 are installed in and are fixed on the body and are configured on the frame supported axle 73 on the left and right directions, become one with planting depth bar 53 and can be centered by frame supported axle 73 and rotate.By planting depth bar 53 is rotated forwards, backwards, left side grounding body support bar 54 and right side grounding body support bar 59 also become one and rotate, thereby can change the upper-lower position of the leading section of left side grounding body support bar 54 and right side grounding body support bar 59.And, according to the turned position of left side grounding body support bar 54 and right side grounding body support bar 59, the upper-lower position of the link pillar circular shaft part 61 that the second grounding body turning cylinder 52 on the left of being fixed on the leading section of grounding body support bar 54 and right side grounding body support bar 59 and axle support changes.Therefore, by left side grounding body support bar 54, right side grounding body support bar 59 and planting depth bar 53 etc., consist of planting depth change mechanism.

Therefore, by regulate the turned position of planting depth bar 53 in front and back, can change the upper-lower position of the rotary middle spindle of left side earthing position detection bodies 36 and right side earthing position detection bodies 37, therefore can according to the planting depth of plantation object, regulate the certain distance between body and the ridge U upper surface.

In addition, such as Figure 35 and shown in Figure 42, on the top, rear of right side cantilever web 71, always think to be formed with side by side three load regulation holes 74, the front end that the rear end is fixed on the right side extension spring 69 on the frame supported axle 73 hangs in the arbitrarily load regulation hole 74.

Utilize right side extension spring 69, in Figure 35, right side earthing position detection bodies 37 is applied the active force that clockwise rotates.Tangle the position in load regulation hole 74 of the front end of right side extension spring 69 by change, thereby the active force that is applied on the right side earthing position detection bodies 37 is changed.Namely, according to the position in the load regulation hole 74 of the front end that tangles right side extension spring 69, can regulate the ground connection load in 37 pairs of farmlands of earthing position detection bodies, right side.And along with the adjusting of the ground connection load of right side earthing position detection bodies 37, the control sensitivity of elevating control changes.

For left side earthing position detection bodies 36 too, top, rear at left side cantilever web 66, vertically be formed with side by side three load regulation holes 74, the front end that the rear end is fixed on frame supported axle 73 upper left side extension springs 68 hangs in the arbitrarily load regulation hole 74, becomes the structure of the ground connection load that can regulate 36 pairs of farmlands of earthing position detection bodies, left side.

Then, reasons such as having soil block because the farmland is coarse, the action when only a side of left side earthing position detection bodies 36 and right side earthing position detection bodies 37 detects the variation of the distance from body to ridge U upper surface are described.

, as an one example, illustrate that ridge U upper surface does not change with respect to the position of the body of left side earth plate 65 sides here, and the situation when there is soil block in the ridge U of right side earth plate 70 sides.

If there is soil block in the right side at the ridge U that right side earth plate 70 contacts, then right side earth plate 70 is lifted along this soil block, in Figure 35, only right side earthing position detection bodies 37 is rotated to counter clockwise direction centered by being configured in the link pillar circular shaft part 61 on the left and right directions.

If right side earthing position detection bodies 37 is to counterclockwise rotating, an end parts of the cantilever lever section 63 that then the right side long slot bore 173 with right side earthing position detection bodies 37 is cooperated applies to the power in body the place ahead, and cantilever 50 is applied to the power in body the place ahead.At this moment, because left side earthing position detection bodies 36 do not rotate, another distolateral power that it is forwards moved that applies of the cantilever lever section 63 that therefore the left side long slot bore 168 with left side earthing position detection bodies 36 is not cooperated.Because the cantilever shaft sleeve part 64 of cantilever 50 is fixed on the middle position at two ends of cantilever lever section 63, so cantilever shaft sleeve part 64 moves the half-distance of displacement of right side one end parts of cantilever lever section 63.

Therefore, on the link pillar circular shaft part 61 that connects cantilever shaft sleeve part 64, apply the power to body the place ahead corresponding with a half-distance of the displacement of right side one end parts of cantilever lever section 63.And according to this power to body the place ahead, cantilever links pillar 51 and rotates to counter clockwise direction centered by being configured in the link pillar circular shaft part 61 on the left and right directions.

If cantilever links pillar 51 to counterclockwise rotating, then hydraulic stem 55 is applied the power that moves to body the place ahead, the rotation post 56 that links with the other end of hydraulic stem 55 rotates to clockwise direction centered by rotation post axle 58.If rotation post 56 rotates to clockwise direction, the connecting rod 57 that then links with the other end of rotation post 56 is moved upward.Connecting rod 57 amount of movement upward of this moment is the amount of movement corresponding with a half-distance of the displacement of right side one end parts of cantilever lever section 63.

According to connecting rod 57 amount of movement upward, the hydraulic switch valve section 24 that links with the other end of connecting rod 57 makes hydraulic lifting cylinder 23 actions by elevating control with switching valve, descends by making left and right sides trailing wheel 14, and body rises with respect to ridge U upper surface.

At this moment, body with respect to the amount of movement that ridge U upper surface rises is, by half of the converted quantity of the detected ridge U close to above-below direction of left side earthing position detection bodies 36.

Be controlled to be in the link gear of certain altitude at the height with the body of present embodiment, variable quantity part after the corresponding variable quantity equalization that moves up and down that will be detected separately by left side earthing position detection bodies 36 and right side earthing position detection bodies 37, the lifting of control body body.Since with about two left sides earthing position detection bodies 36 and right side earthing position detection bodies 37 of the configuration detection equalization of carrying out detect the farmland face and detect, even therefore have soil block at ridge U, body can not change up and down significantly yet, but carry out stable elevating control, can realize suitableization of elevating control.

In addition, as shown in figure 35, the link gear that the body height of present embodiment is controlled to be certain altitude adopts following structure: by linking cantilevers 50 than their turning cylinder 52, left side long slot bore 168 and the right side long slot bore 173 of 61 top location, the position correspondence left side earthing position detection bodies 36 of cantilever 50 and the position that moves up and down of right side earthing position detection bodies 37 change with left side earthing position detection bodies 36 and right side earthing position detection bodies 37.And, two ends are attached on the link pillar circular shaft part 61 that cantilever links pillar 51 by the cantilever shaft sleeve part 64 of the middle position that is positioned at cantilever lever section 63 that links with left side earthing position detection bodies 36 and right side earthing position detection bodies 37, in the position than turning cylinder 52,61 top sides, cantilever links pillar 51 and is attached on the hydraulic stem 55, therefore becomes small-sized structure as link gear integral body.

In addition, as shown in figure 35, when observing in the side, the position configuration that the cantilever that links with left side earthing position detection bodies 36 and right side earthing position detection bodies 37 links pillar 51 and an end of the V-shape that links of hydraulic stem 55 be hydraulic stem linking part 62 and and the shaft portion of the link pillar circular shaft part 61 that links of cantilever shaft sleeve part 64 between.

In addition, in the present embodiment, the sensor 42 that tilts of pendulum is set, utilizing this detection that tilts sensor 42 to make to tilt with hydraulic cylinder 25 actions the body that will travel to be maintained the structure of left and right horizontal is illustrated, but be not limited thereto, also can make and for example do not possess the sensor of tilting 42, tilt with the structure of the rotary regulating lever of the manual type of hydraulic cylinder 25 with manual control but possess operator itself.

Figure 45 is the approximate vertical view of rotary regulating lever of a variation of the cigarette seeding transplant machine 10 of explanation in the present embodiment.

In addition, Figure 46 represents the approximate vertical view of rotary regulating lever part, and Figure 47 represents to tilt with switching valve approximate vertical view partly.

In cigarette seeding transplant machine 10 shown in Figure 45, with rotary regulating lever 47 be arranged on when controlling control crank 16 can the maneuverable control crank 16 of enough left hands part.

Rotary regulating lever 47 connects with regulating cable 48 by tilting with switching valve 46 with being connected.In addition, in Figure 45, omitted and tilted with the diagram of regulating cable 48.

The action bars section 127 that rotary regulating lever 47 is used by manual operation and consist of from the adjusting arm 128 that extends to right angle orientation of action bars section 127 midway.On the dwang fulcrum 126 that is arranged on the rotating fulcrum section that becomes on the control crank 16, the parts of rotating earth's axis support operation bar section 127 freely with regulate arm 128 and link.

Be connected with the neutral retracting spring 125 that an end is fixed on the control crank 16 with the end of a manual side opposition side in the action bars section 127, become the structure that is stretched by neutral retracting spring 125.After with hand action bars section 127 being operated, if hand is left action bars section 127, then rotary regulating lever 47 returns the neutral position of not carrying out tilt operation by the active force of neutral retracting spring 125.

Link to tilt with an end of regulating cable 48 at the front end of regulating arm 128.By centered by dwang fulcrum 126 with hand rotating operation bar section 127, thereby the front end of regulating arm 128 also rotates, and follows in this, tilts mobile in the longitudinal direction with regulating cable 48.And, this inclination with the amount of movement of the length direction of regulating cable 48 be passed to tilt distolateral with regulating another of cable 48.

In addition, when rotary regulating lever 47 is neutral condition, and regulates inclination that arm 128 the links direction with an end parts of adjusting cable 48 and be configured to parallel with the direction of the length direction of action bars section 127.By this configuration, can prevent from regulating the stained of cable 48.In addition, meet at right angles take action bars section 127 as baseline configuration owing to regulating arm 128, therefore, by this configuration, can take in compactly rotary regulating lever 47.
