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 extension 224b that the recess 223 of plantation transmission case 26 leans on rear side to prolong, this extension 224b is configured in the top of the front portion (preceding swing arm of afterwards stating 80 and left back swing arm 81) of up-down link mechanism 29.

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

Figure 12 representes the amplification plan view of plantation clutch of other examples of this embodiment, and Figure 13 representes to be used to explain the major part amplification plan view of the effect of this plantation clutch.

Left and right sides the opposing party's side (right side) that plantation clutch 212 shown in this embodiment and precedent likewise are configured in 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 connection and cut-out to the transmission of oscillating cam driving shaft 88.In addition, on driving side corpus unguis 213 and slave end corpus unguis 214, be respectively equipped with intermeshing four and cooperate pawl 213a and four cooperation pawl 214a.

Promptly, 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 and be arranged on the chimeric structure of 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 move left and right assembled construction 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 by inclined plane 215a with stop to constitute with contact-making surface 215b; This inclined plane 215a through contact after the operative pin 216a that states and oscillating cam driving shaft 88 is rotated to arrow F direction; Thereby slave end corpus unguis 214 is moved to the direction of leaving driving side corpus unguis 213, break off 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 breaks off is come the moment just over the position of the lifting position of its track 17 for plantation utensil 28 through up-down link mechanism 29.Therefore, plantation clutch 212 utilizes the inertia force that the plantation utensil 28 just over lifting position will move downward and breaks off reliably.And; After plantation clutch 212 breaks off reliably; Plantation utensil 28 inertia force that will move downward is through diminishing to the active force of the afterburning following plantation clutch spring 217 of inclined plane 215a that operative pin 216a contacted and slave end corpus unguis 214 gradually, operative pin 216a with stop to contact and making planting utensil 28 and suitably stop at assigned position with contact-making surface 215b.

In this embodiment; Be to adopt following structure with the difference of the foregoing description: on slave end corpus unguis 214; Be provided with the engagement dog 214c that rotational fixation is used with a side left and right sides opposition side that is provided with engaged claw 214a; Fixation side engagement dog 26a is set on plantation transmission case 26, and this fixation side engagement dog 26a cooperates with this engagement dog 214c and makes slave end corpus unguis 214 stop at the precalculated position.

Promptly 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 the transmission of plantation clutch 212 as stated.Otherwise; Connect the direction operation if will plant clutch lever 161 to the plantation clutch; The operative pin 216a that then plants clutch operating mechanism 216 returns the leave operation cam 215 with operation of cam 215 opposition sides (rear side); Driving side corpus unguis 213 meshes through plantation clutch spring 217 with slave end corpus unguis 214, and plantation clutch 212 becomes drive state.

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

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, and the fixation side engagement dog 26a engagement of the engagement dog 214c that can prevent slave end corpus unguis 214 and the plantation transmission case 26 of fixation side and the engaged claw 213a of driving side corpus unguis 213 and the engaged claw 214a of slave end corpus unguis 214 are meshed with stationary state; Thereby plantation clutch 212 becomes drive state, can prevent that thus transmission mechanism is damaged.

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

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 this embodiment and secondary variable speed operation.

In above-mentioned example; Represented through 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 and slave end gear 202 is slided on the 3rd 203 to the left and right to the left and right; Thus slave end gear 202 for three driving side gear 201a, 201b, 201c in any engagement and change the example that carries out the spacing in the rows variable speed operation; But in the example shown in Figure 14, adopt following structure: the 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.

Promptly, 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 bolt are arranged on the right side wall of main transmission box 12.In addition, can be operated at left and right directions for action bars 280, this through hole 281a is bigger slightly 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; The fixing base portion that extends the secondary variable speed operation arm 282 that is provided with towards the top of welding is attached at the upper end of this pair variable speed operation arm 282 from the outstanding secondary variable speed operation bar 283 that is provided with 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, the top of then secondary variable speed operation arm 282 is by to the operation of arrow D-E direction, and secondary variable speed operation bar 283 links with it and 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).

In addition; Middle part at action bars 280; Welding is provided with the base portion that extends the spacing in the rows shifting arm 284 that is provided with towards plantation transmission case 26 sides regularly; And linking displacement bar 285, this displacement bar 285 makes above-mentioned linkage portion 206 move left and right in the set circular-arc slotted hole 284a of the leading section of this spacing in the rows shifting arm 284.

In addition, the axle center that circular-arc slotted hole 284a becomes with action bars 280 is the circular arc at center, and becomes the structure among this circular-arc slotted hole 284a of pin 285a insertion that is fixed on displacement bar 285.Therefore, even in order to change the secondary variable speed operation of travel speed and operating speed, hold the operating handle 280a of action bars 280 and carry out rotating operation, displacement bar 285 can move left and right yet, can not carry out the spacing in the rows speed change.

In the occasion of carrying out the spacing in the rows speed change, if hold the operating handle 280a of action bars 280 and action bars 280 carried out left and right directions operation, the displacement bar 285 move left and right distance between rows and hills speed change of going forward side by side then.In addition; In the top position of action bars 280 and the anterior position of operating handle 280a; For clear and definite spacing in the rows variable speed operation position; On the sidewall of plantation transmission case 26, be fixed with spacing in the rows variable speed operation position display mark 286, this spacing in the rows variable speed operation position display mark 286 is configured in from the position that control crank 16 sides at body rear can be seen, and; Because with secondary variable speed operation during to operating speed (low speed); The operating handle 280a of variable speed operation bar 280 becomes vertical configuration up, so the operator can easily discern spacing in the rows variable speed operation position with the position of spacing in the rows variable speed operation position display mark 286 corresponding operating handle 280a, and operating characteristics is good.

Secondly, based on Figure 15 and Figure 16, describe making the body ridge guide 160 that U goes along the ridge.Figure 15 representes to be used to explain the amplification plan view of effect of the guide roller operate portions of cigarette seeding transplant machine 10, and Figure 16 representes to be used to explain the enlarged side view of the effect of guide roller operate portions.

Ridge in left and right sides front-wheel 13 and the left and right sides trailing wheel 14 leap farmlands and then go and with above-mentioned feed mechanism for seedling tool 28 seedling is carried out in rice shoot plantation on the U of ridge and transplant operation; Ridge guide 160 is arranged on the front portion of body; Face contacts about each left and right sides guide roller 261 and this ridge U, and U's guiding body goes along the ridge.

Left and right sides guide roller 261 is separately positioned on and starts the airborne left and right sides of putting platform 191 because left and right sides guide roller 261 is same structures, therefore, below as representative, left guide roller 261 is described.

Starting the airborne base portion of putting the side welding fixed guide roller supporting pin 262 of platform 191.And this guide roller supporting pin 262 is structures of the offside decline inclination attitude in the below in the more past outside of its front end.

Mode with embedding outside rotating freely on guide roller supporting pin 262 is provided with cylindric axle sleeve 264; This cylindric axle sleeve 264 is arranged on the base portion of guide roller support arm 263; In the set cylindric support sleeve 265 of the leading section of guide roller support arm 263; Upper-lower position is regulated and is connected roll shaft 267 and fixing with bolt 268 freely, and above-mentioned roll shaft 267 rotations are provided with the roller 266 of resinous cylinder freely.

In addition; On the cylindric axle sleeve 264 with link metal wire 270 link towards above the vertical motion arm 269 that is provided with and the work through above-mentioned hydraulic lifting cylinder 23 make that trailing wheel 14 goes up and down on side arm 40a; In the knee-action of the trailing wheel 14 when common plantation operation; Because it is lax to link metal wire 270; Vertical motion arm 269 does not move, and when body turns round, makes trailing wheel 14 drop to maximum figure and links the lax tensioning of metal wire 270 when making body rise to maximum and vertical motion arm 269 is rotated towards the rear, thereby guide roller 261 is kept out of the way to the top of leaving ridge U.

At this moment; Rotate the guide roller supporting pin 262 of the cylindric axle sleeve 264 that supports the base portion that is located at guide roller support arm 263 freely owing to be the structure of the offside decline inclination attitude in the below in the more past outside of its front end; Therefore left and right sides guide roller 261 is separated from each other and rises to opening direction, does not rise well contiguously with ridge U face.Therefore; To plant clutch lever 161 to the operation of plantation clutch cutting direction; And make left and right sides trailing wheel 14 drop to maximum figure and make body rise to maximum and make body when revolution; Simultaneously, left and right sides guide roller 261 does not rise with ridge U face in the direction that is separated from each other and opens contiguously well, can be easily and suitably carry out the revolution operation of body.

In addition; Be formed with the concavo-convex 264a of wave in the outside of cylindric axle sleeve 264; Become and be arranged on and fix the mechanism that cooperates with the axle sleeve 271 inboard concavo-convex 271a of wave, said fixing is rotated outer freely being embedded on the guide roller supporting pin 262 with the outside that axle sleeve 271 is arranged in cylindric axle sleeve 264.

And; Cylindric axle sleeve 264 passes through energizing spring 272 to fixing with axle sleeve 271 sides by reinforcing; The concavo-convex 264a of wave through cylindric axle sleeve 264 outsides meshes with the axle sleeve 271 inboard concavo-convex 271a of wave with fixing, left and right sides guide roller 261 the body direction of advance guiding function position that contacts with ridge U and to above the fixed-site of keeping out of the way.

In addition; Damaged in order to prevent left and right sides guide roller 261 with the barrier collision; As stated that kind make cylindric axle sleeve 264 through energizing spring 272 to fixing with axle sleeve 271 sides by reinforcing, thereby the concavo-convex 264a of wave in cylindric axle sleeve 264 outsides meshes with the fixing concavo-convex 271a of wave with axle sleeve 271 inboards.Therefore, when guide roller 261 during with the barrier collision, the active force of opposing the energizing spring 272 and engagement of the concavo-convex 264a of each wave, 271a is thrown off, cylindric axle sleeve 264 rotates, and guide roller 261 is kept out of the way to the side away from barrier, can prevent breakage.

And, fixing with axle sleeve 271 on towards below setting operation arm 273, link with plantation clutch lever 161 through linking metal wire 274.Promptly; If will plant clutch lever 161 to connecting the plantation clutch operating, then pulling links metal wire 274,261 declines of left and right sides guide roller and respectively with ridge U about face contact; Become the guiding body guiding function state that U goes along the ridge; Link metal wire 274 if will plant clutch lever 161 to cutting off the plantation clutch operating, then unclamping, left and right sides guide roller 261 becomes the state that can rise when above-mentioned body turns round.

Through 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 preceding swing arm 80 are through the swing forwards, backwards with the live-rollers 87 of wobble drive cam 84 butts.At this moment, also swing forwards, backwards with the right back swing arm 99 that left back swing arm 81 links through last rear axle 90 with left back swing arm 81.

On the other hand; Through 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 left underarm 83 and bottom right arm 97 swing up and down through armite 86 and left and right sides connecting rod 98, and upper arm 82 also swings up and down with left underarm 83.

Therefore; Preceding swing arm 80, left back swing arm 81 and right back swing arm 99 all are parallel linkage mechanisms with upper arm 82, left underarm 83 and bottom right arm 97; Therefore planting utensil 28 keeps the posture towards vertical direction; Move with 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, shown in figure 19, the cultivation device 19 of this 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 the rotation lower shaft 96 that links left underarm 83.

Be configured in than rotate go up axle 95 on the front through rotating lower shaft 96, thereby the interval of upper arm 82 and left underarm 83 narrows down can suppress to plant utensil 28 and descend the time.

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

Shape and the wobble drive cam 84 of setting wobble drive cam 84 as follows are fixed on the mode on the oscillating cam driving shaft 88; This mode is: diminish in the diameter variation of supplying with the position of seedlings to plantation utensil 28, promptly plant near the wobble drive cam 84 of utensil 28 when being positioned at the top dead centre of track 17 of action and the wobble drive cam 84 of live-rollers 87 position contacting; The diameter variation of in addition, in the position of plantation seedling, promptly planting near the wobble drive cam 84 of utensil 28 when being positioned at the lower dead center and the wobble drive cam 84 of live-rollers 87 position contacting becomes big.

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 is in the linearity position overlapped with armite 86 in vertical direction, and, become the structure parallel with preceding swing arm 80, left back swing arm 81 and right back swing arm 99.Therefore; Set the direction of crank arm 85 as follows: when plantation utensil 28 is supplied with seedlings, plant near utensil 28 and position of plantation seedling when being positioned at the top dead centre, 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 through plantation utensil 28 moves with the mode of the track 17 of describing ring-type, and near the translational speed of the plantation utensil 28 of top dead centre, (supplying with the position of seedling) 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 consistently, 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 and preceding swing arm 80, left back swing arm 81 and right back swing arm 99 are parallel to each other; Therefore swing arm 80, left back swing arm 81 and moving up and down of right back swing arm 99 tail off before, can move up and down through what crank arm 85 and armite 86 carried out, and plantation utensil 28 is more promptly moved.

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, promptly leans on the bottom at the center than the width that moves up and down of plantation utensil 28, and the width of front and back be a maximum.Position below leaning on than the width center that moves up and down of front end of plantation utensil 28, the front and back width of quiet track 17 be maximum, so the moving track of tree-remover when going 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 constitutes by upper arm 82, left underarm 83 and bottom right arm 97 of cultivation device 19.Owing to drive, so can suppress the plantation undesirable condition that the gap of transmission system causes with the crank arm 85 of an axle.

In addition, through wobble drive cam 84 above-mentioned up-down link mechanism 29 is moved forward and backward.Owing to be to use the structure of 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 last rear axle 90, promptly near on the position as the oscillating cam driving shaft 88 of the fulcrum of preceding 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 goes 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.Through making the scope of plantation utensil 28 in charging into soil is the quiet track of toroidal, thereby can reduce to plant the hole.

In addition; Above leaning on, locate the shape that diminishes for the front and back width than planting depth through the track 17 described of front end that makes plantation utensil 28; 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; Because utilizing the left back swing arms 81 of 167 pairs of extension springs gives and the power of lifting to oblique front upper place; Therefore can prevent that at plantation utensil 28 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 the plantation position descends.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; Through crank arm 85 is rotated counterclockwise among the Figure 18 that observes from right side side; Crank arm 85 to opposite spin, therefore 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 easily.Through 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, preceding swing arm 80, left back swing arm 81 and right back swing arm 99 direction rear action in the past, but the rotation connection shaft of the front end of crank arm 85 106 forwards rotates from the rear.Because preceding swing arm 80, left back swing arm 81 and right back swing arm 99 move to ground with crank arm 85 relatively; 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 goes of body of plantation utensil 28 front ends is also little.

In addition; Near lower dead center; Because crank arm 85 and armite 86 are in vertical direction or approach on the direction of vertical direction point-blank, crank arm 85 carries out move up and down with armite 86 be formed slopely move up and down consistently, so can accelerate to plant the rate of climb of utensil 28.

Have again; Near lower dead center; Preceding swing arm 80, left back swing arm 81 and right back swing arm 99 are parallel with crank arm 85 and armite 86; Thereby preceding swing arm 80, left back swing arm 81 and moving up and down of right back swing arm 99 tail off, and move up and down through what crank arm 85 and armite 86 carried out, and 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, and expression is from the figure of the left sides of body.

Shown in figure 24, in the cultivation device 19 of this embodiment, oscillating cam driving shaft 88 is configured on the position of roughly the same height with crank arm driving shaft 89.And, about connect cultivation device driving box 27 last rear axle 90 be configured in than the center straight line each other that links oscillating cam driving shaft 88 and crank arm driving shaft 89 by on the position of below.

Be passed to oscillating cam driving shaft 88 from plantation transmission case 26 to the driving force that cultivation device driving box 27 transmits.And in cultivation device driving box 27, through 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, leans on the position of below on last rear axle 90 because being configured in than the center straight line each other 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 last rear axle 90, can driving force stably be transmitted to crank arm driving shaft 89.In addition, according to this configuration, can dispose oscillating cam driving shaft 88, crank arm driving shaft 89 compactly and go up rear axle 90.

Secondly, describe being used to open and close the 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 planting utensil 28 freely.In addition,, rotate switching arm 101 is set freely, utilize connecting rod 103 to link and open and close arm 101 and auxiliary 104 going up on the axle 92 of the other end that is arranged at upper arm 82 (front end).In addition, pin 105 is set on auxiliary 104.

In addition, setting is fixed on the oscillating cam driving shaft 88 and the driven for opening and closing cam 100 of rotation with wobble drive cam 84, and the switching that rotation setting freely contacts with the circumference of driven for opening and closing cam 100 on switching arm 101 is with roller 102.The rotation that is accompanied by oscillating cam driving shaft 88 through driven for opening and closing cam 100 is rotated, thereby through opening and closing with roller 102 switching arm 101 is moved.

About the on-off action of plantation utensil 28, auxiliary 104 moves with opening and closing arm 101 through connecting rod 103 simultaneously, opens and closes arm 101 and moves with roller 102 and through driven for opening and closing cam 100 by means of opening and closing.Thereby, can set switching time and switching amount with high accuracy through the driven for opening and closing cam 100 of simple shape.

Figure 25 is the figure of the track that moves of the leading section of the plantation utensil 28 observed from the rear of body of explanation.

The support 291 that plantation utensil 28 is equipped with is made up of left socle 291L and right support 291R, and left socle 291L one is fixed on the left-hand side part 109L, and right support 291R one is fixed on the right side members 109R.Be that left socle 291L rotates around the left fulcrum shaft 225 of fore-and-aft direction; Right support 291R is around the structure of right fulcrum shaft 226 rotations of fore-and-aft direction; With axle 227, link left socle 291L and right support 291R through the interlock on the left and right directions middle position that is arranged on plantation utensil 28.In addition, on the rotating operation arm 228 that is wholely set with left socle 291L, link the opening 231 of extending, and the pin 105 of auxiliary 104 is attached on the opening 231 to above-below direction.In addition; Be following structure: switching is set between left socle 291L and right support 291R with spring 230; Open and close spring force through this with spring 230, left-hand side part 109L and right side members 109R each other to the left and right the direction inboard be pressed, plant the bottom of utensil 28 and close.In addition, through opening and closing the spring force with spring 230, not only switching also is pressed to driven for opening and closing cam 100 sides (upside) with roller 102 but also switching arm 101.

If driven for opening and closing cam 100 rotates with the rotation of oscillating cam driving shaft 88, then open and close and move according to driven for opening and closing cam 100 peripheral shapes with roller 102, open and close arm 101 swings.Be accompanied by the swing that opens and closes arm 101; Connecting rod 103 direction action forwards, backwards; Auxiliary 104 rotates, and opening 231 is moved along the vertical direction, when through rotating operation arm 228 left socle 291L being rotated; With axle 227 right support 291R is rotated through interlock, thereby make left socle 291L and right support 291R open and close the bottom of planting utensil 28 to symmetrical rotated position each other on the contrary.Specifically, follow the action of connecting rod 103, make opening 23 1 to upside action, the bottom of opening plantation utensil 28 to the front side.In addition, when plantation utensil 28 rises, utilize the jut of the part of driven for opening and closing cam 100 peripheries, the bottom of plantation utensil 28 is temporarily opened wide significantly, the cleaning that is provided with in addition can be along the vertical direction through in the plantation utensil 28 with scraper plate.

In Figure 20 and position shown in Figure 21, driven for opening and closing cam 100 does not contact and opens and closes with roller 102, in top dead centre and the position that descends from top dead centre, keeps the bottom closing state of planting utensil 28.

In the position of the lower dead center of Figure 22, driven for opening and closing cam 100 begins contact and opens and closes with roller 102, and in the position of the Figure 23 that rises from lower dead center, driven for opening and closing cam 100 is in and continues the state of contact switching with roller 102.

Therefore, plantation utensil 28 was kept the bottom closing state before dropping to lower dead center, and in the position of lower dead center, the bottom begins to open, and the state of opening with the lower dead center bottom begins to rise.Promptly, near the stroke that the top dead centre of track 17, descends, the bottom of plantation utensil 28 is in closing state, in lower dead center, open the bottom of plantation utensil 28, from the stroke that lower dead center rises, the bottom of plantation utensil 28 is in the state of opening.

As stated; Axle is supported on and links the lifting position that the auxiliary 104 on the axle 95 in the rotation that upper arm 82 is arranged does not rely on upper arm 82 and left underarm 83; But move simultaneously with opening and closing arm 101 through connecting rod 103, this opens and closes arm 101 through opening and closing with roller 102 by driven for opening and closing cam 100 control actions.Therefore, can realize the high-precision control of switching time and switching amount through the driven for opening and closing cam 100 of simple shape.

In addition, also can adopt driven for opening and closing cam 100 is fixed on the crank arm driving shaft 89 that drives crank arm 85, with the structure of crank arm 85 one rotation.

In addition, in this embodiment, be installed in as the going up on spools 92 of the binding fulcrum shaft of upper arm 82 owing to will open and close arm 101, thereby become simple structure.In addition, all parallel no matter the lifting position of connecting rod 103 up-down link mechanisms 29 is how with upper arm 82 and left underarm 83, therefore can set the opening of plantation utensil 28 through driven for opening and closing cam 100 with high accuracy.In addition, no matter owing to adopt to open and close which structure of all linking with the rotating fulcrum axle of upper arm 82 of arm 101 and auxiliary 104, so connecting rod 103 disposes and becomes compact structure along upper arm 82.In addition, because driven for opening and closing cam 100 is installed on the oscillating cam driving shaft 88 as the rotating fulcrum axle of preceding swing arm 80 with wobble drive cam 84, thereby become simple structure.

In addition, also can make following structure: the linking portion with auxiliary 104 at connecting rod 103 is provided with adjustment screw such as degree of tightness screw buckle, utilizes this adjustment screw, can regulate the length that opens and closes the connecting rod 103 between arm 101 and the auxiliary 104.Through in this position adjustment screw being set, the opening that can regulate plantation utensil 28 from the rear of plantation utensil 28.

Shown in figure 19, in the cultivation device 19 of this embodiment, make the switching of plantation utensil 28 sides littler than the switching of cultivation device driving box 27 sides with the radius of gyration L2 of input arm (opening and closing arm 101) with the radius of gyration L1 of output arm (auxiliary 104).

Radius of gyration L1 through making auxiliary 104 is littler than the radius of gyration L2 that opens and closes arm 101, thereby auxiliary 104 is gone up axle 95 around rotation and rotated with than opening and closing the big rotational angle of rotational angle of arm 101 around last axle 92.

Therefore, plantation utensil 28 is opened and closed.

In addition; Owing to can reduce to be used to plant the rotational displacement that utensil 28 makes the switching arm 101 of switching; Therefore can be with being used to make the shape on every side that opens and closes the driven for opening and closing cam 100 that moves with roller 102 to make the little shape of variable quantity of radius, can be with 100 miniaturizations of driven for opening and closing cam.

In addition,, therefore can make seedling guide 108 step-downs, and make the position step-down of supplying with turntable 32 owing to can shorten auxiliary 104.The stroke that in addition, can strengthen up-down link mechanism 29 strengthens the amplitude that moves up and down of planting utensil 28.

With regard to plantation utensil 28, the bottom is made up of left-hand side part 109L and right side members 109R, and when plantation utensil 28 descended, each fore-end of left-hand side part 109L and right side members 109R left and opens, with bed out young plants.

In Figure 25, dot the track of the leading section of left-hand side part 109L, represent the track of the leading section of right side members 109R with double dot dash line.

Left-hand side part 109L and right side members 109R open and bed out young plants near the lower dead center of plantation utensil 28, then, under the state of opening, rise, and before being supplied to rice shoot from supply turntable 32, close, and next rice shoot is supplied in the plantation utensil 28.

Through making the change of shape on every side of driven for opening and closing cam 100, cultivation device 19 can freely be regulated the switching time and the opening and closing speed of plantation utensil 28.

When left-hand side part 109L and right side members 109R open, generate the velocity component and the velocity component upwards of direction to the left and right at their leading section.On the other hand, through up-down link mechanism 29, on whole plantation utensil 28, produce downward velocity component till lower dead center.

In this embodiment; According to when plantation utensil 28 is opened; The velocity component that makes progress that produces at each fore-end of left-hand side part 109L and right side members 109R and axle 95 in the rotation for example is installed and is rotated the setting that the downward velocity component of the part of lower shaft 96 equates in the part of not carrying out on-off action of plantation utensil 28; Be the setting that these velocity components are offset, set the shape of driven for opening and closing cam 100 and to the setting angle of oscillating cam driving shaft 88.

At plantation utensil 28 when opening, be zero at the velocity component of the above-below direction of each fore-end of left-hand side part 109L and right side members 109R, so each fore-end of left-hand side part 109L and right side members 109R flatly move with respect to the farmland face.

Therefore, open, on the face of farmland, form smooth hole through each fore-end of left-hand side part 109L and right side members 109R, can ground attractive in appearance bed out young plants.

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

Through moving up and down of connecting rod 57, hydraulic lifting cylinder 23 moves with switching valve by means of the up-down control that is equipped with in the hydraulic pressure switching valve portion 24, and left and right sides trailing wheel 14 goes up and down.

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, near body, then the U upper surface is lifted along the ridge for left side earth plate 65 and right side earth plate 70 as if ridge U upper surface, and away from body, then the U upper surface descends along the ridge for left side earth plate 65 and right side earth plate 70 as if 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 with second coaxial on the left and right directions grounding body turning cylinder 52 and link pillar circular shaft part 61 and counterclockwise rotate for middle mind-set.

If left side earthing position detection bodies 36 and right side earthing position detection bodies 37 are to counterclockwise rotating; The cantilever lever portion 63 that then two ends is cooperated with left side long slot bore 168 and right side long slot bore 173 applies the power to body the place ahead; Through cantilever 50 is applied the power to body the place ahead; Thereby to the power that the binding pillar circular shaft part 61 that connects cantilever shaft sleeve part 64 applies to body the place ahead, cantilever links pillar 51 and counterclockwise rotates for middle mind-set with the binding pillar circular shaft part 61 that is configured 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 be middle mind-set clockwise direction rotation with rotation post axle 58.If rotation post 56 rotates to clockwise direction, the connecting rod that then links with the other end of rotation post 56 57 moves to the top.

If connecting rod 57 moves to the top, the hydraulic pressure switching valve portion 24 that then links with the other end of connecting rod 57 makes hydraulic lifting cylinder 23 actions through the control of going up and down with switching valve, thereby left and right sides trailing wheel 14 descends.

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

When the plantation operation of carrying out rice shoot; Under the situation of ridge U upper surface away from body; The U upper surface descends along the ridge for left side earth plate 65 and right side earth plate 70; 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.Just, this occasion, connecting rod 57 moves downwards, and hydraulic pressure switching valve portion 24 makes hydraulic lifting cylinder 23 actions through the control of going up and down with switching valve, and left and right sides trailing wheel 14 is risen.Promptly, 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.

Through this control, when the U upper surface was near body or away from body on the ridge, the distance of body and ridge U upper surface all remained certain distance, so the plantation of rice shoot can not crossed dark or shallow excessively.

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 that rotate at the center with frame supported axle 73.Through 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 binding pillar circular shaft part 61 that 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, through left side grounding body support bar 54, right side grounding body support bar 59 and planting depth bar 53 etc., constitute planting depth change mechanism.

Therefore; Through 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 regulate the certain distance between body and the ridge U upper surface according to the planting depth of plantation object.

In addition, like Figure 35 and shown in Figure 42, three load regulation holes 74 are always thought to be formed with side by side in the top, rear of cantilever web 71 on the right side, and 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 hole of load regulation arbitrarily 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 through change, thereby the active force that is applied on the right side earthing position detection bodies 37 is changed.Just, 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 the control of going up and down changes.

For left side earthing position detection bodies 36 too; The top, rear of cantilever web 66 in the left side; Vertically be formed with three load regulation holes 74 side by side; The front end that the rear end is fixed on frame supported axle 73 upper left side extension springs 68 hangs in the hole of load regulation arbitrarily 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 of the farmland is coarse, the action when only the side detection of left side earthing position detection bodies 36 and right side earthing position detection bodies 37 is from the variation of body distance of U upper surface to the ridge are described.

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

If there is soil block in the right side of the ridge U that earth plate 70 is contacted on the right side; Then right side earth plate 70 is lifted along this soil block; In Figure 35, only right side earthing position detection bodies 37 is counterclockwise rotated for middle mind-set with the binding pillar circular shaft part 61 that is configured 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 portion 63 that then the right side long slot bore 173 with right side earthing position detection bodies 37 is cooperated applies the power to body the place ahead, and cantilever 50 is applied the power to body the place ahead.At this moment, because left side earthing position detection bodies 36 do not rotate, another distolateral its forwards mobile power that makes that applies of the cantilever lever portion 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 portion 63, so cantilever shaft sleeve part 64 moves the half-distance of displacement of right side one end parts of cantilever lever portion 63.

Therefore, on the binding pillar circular shaft part 61 that connects cantilever shaft sleeve part 64, apply the corresponding power of a half-distance to body the place ahead with the displacement of right side one end parts of cantilever lever portion 63.And according to this power to body the place ahead, cantilever links pillar 51 and counterclockwise rotates for middle mind-set with the binding pillar circular shaft part 61 that is configured 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 be middle mind-set clockwise direction rotation with rotation post axle 58.If rotation post 56 rotates to clockwise direction, the connecting rod that then links with the other end of rotation post 56 57 moves to the top.The connecting rod 57 of this moment is the corresponding amount of movement of a half-distance with the displacement of right side one end parts of cantilever lever portion 63 to the amount of movement of top.

According to the amount of movement of connecting rod 57 to the top, the hydraulic pressure switching valve portion 24 that links with the other end of connecting rod 57 makes hydraulic lifting cylinder 23 actions through the control of going up and down with switching valve, descends through 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 does, half the by the converted quantity of the detected ridge U that approaches above-below direction of left side earthing position detection bodies 36.

Height with the body of this embodiment is controlled to be in the link gear of certain altitude; 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, control body body goes up and down.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 on the U of ridge, have soil block; Body can not change up and down significantly yet; But carry out stable up-down control, can realize suitableization of control.

In addition; Shown in figure 35; The link gear that the body height of this embodiment is controlled to be certain altitude adopts following structure: lean on the left side long slot bore 168 of top position and right side long slot bore 173 to link cantilevers 50 through the turning cylinder 52,61 than them left side earthing position detection bodies 36 and right side earthing position detection bodies 37, 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.And; Two ends are attached on the binding 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 portion 63 that links with left side earthing position detection bodies 36 and right side earthing position detection bodies 37; Position above leaning on than turning cylinder 52,61; Cantilever links pillar 51 and is attached on the hydraulic stem 55, therefore becomes small-sized structure as link gear integral body.

In addition; Shown in figure 35; When viewed, 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 binding pillar circular shaft part 61 that links of cantilever shaft sleeve part 64 between.

In addition; In this embodiment; The sensor 42 that tilts of pendulum is set, utilizes this detection that tilts sensor 42 to make to tilt with hydraulic cylinder 25 actions the body that will go to be maintained the structure of left and right horizontal and be 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 this embodiment.

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