Secondly, the action of the cultivation device 19 to present embodiment describes.
Figure 20～Figure 23 is illustrated in the end view of the cultivation device 19 of the each position in plantation action.Figure 20 is the end view that is illustrated in top dead centre, and Figure 22 is illustrated in the end view of lower dead center.End view when Figure 21 represents to decline from from top dead centre to lower dead center, end view when Figure 23 represents to rise from lower dead center to top dead centre.
Rotate by oscillating cam driving shaft 88, the wobble drive cam 84 being fixed on oscillating cam driving shaft 88 rotates together 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.Now, the right back swing arm 99 linking with left back swing arm 81 by upper rear axle 90 also swings forwards, backwards together with left back swing arm 81.
On the other hand, rotate by crank arm driving shaft 89, the crank arm 85 being fixed on crank arm driving shaft 89 rotates together 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 connecting rod 98, and upper arm 82 also swings up and down together with lower-left arm 83.
Therefore, front swing arm 80, left back swing arm 81 and right back swing arm 99 and upper arm 82, lower-left arm 83 and bottom right arm 97 Dou Shi parallel linkage mechanisms, therefore plant utensil 28 and maintain the posture towards vertical direction, move in the mode of describing to plant track 17 its lower end, the rice shoot being linked in plantation utensil 28 can be planted in the U of ridge with suitable posture.
In addition, as shown in figure 19, the cultivation device 19 of present embodiment, about plantation utensil 28, by the position configuration of rotation lower shaft 96 that links lower-left arm 83 than linking in the rotation of upper arm 82 axle 95 on the front.
By rotation lower shaft 96 being configured in than rotating upper axle 95 on the front, thus can suppress to plant utensil 28 while declining upper arm 82 narrow with the interval of lower-left arm 83.
According to this structure, near plantation utensil 28 is positioned at lower dead center time, can maintain upper arm 82 wider with the interval of lower-left arm 83, therefore under plantation state, can not rock, can carry out stable plantation.
Shape and the wobble drive cam 84 of setting as follows wobble drive cam 84 are fixed on the mode on oscillating cam driving shaft 88, which is: in position from seedling to plantation utensil 28 that supply with, the variation of planting the diameter of the wobble drive cam 84 of the position that near the wobble drive cam 84 of utensil 28 while being positioned at the top dead centre of track 17 of action contact with live-rollers 87 diminishes, in addition, in the position of plantation seedling, the variation of planting the diameter of the wobble drive cam 84 of the position that near the wobble drive cam 84 of utensil 28 while being positioned at lower dead center contact with live-rollers 87 becomes greatly.
According to this structure, can make the translational speed of the front end of planting utensil 28 become, during than plantation seedling, very slow in the time supplying with seedling.
In addition, in top dead centre and lower dead center, crank arm 85 and armite 86 be in vertical direction in 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: to plantation utensil 28 while supplying with seedling, plant utensil 28 while being positioned near top dead centre, and the position of plantation seedling, to plant the armite 86 that near the rotation of the crank arm 85 of utensil 28 while being positioned at lower dead center causes little in the variation of the position of above-below direction.According to this structure, be configured in the time of 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 be supplied to plantation utensil 28 by transplanting object more reliably.
In addition, in the time that 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, what therefore crank arm 85 carried out move up and down with armite 86 be formed slopely move up and down unanimously, can accelerate to plant the action of utensil 28.In addition, in the time that 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 front swing arm 80, left back swing arm 81 and moving up and down of right back swing arm 99 tail off, that can be undertaken by crank arm 85 and armite 86 moves up and down, and makes to plant utensil 28 and more promptly moves.
And, adopt following structure: the width of the front and back by the track 17 described of front end of plantation utensil 28 when the plantation is maximum, than the center portion on the lower of the width moving up and down of plantation utensil 28, the width of front and back be maximum.Than the position on the lower, the width center moving up and down of the front end of plantation utensil 28, the front and back width of quiet track 17 be maximum, and moving track when therefore tree-remover travels becomes linearity carries out upper and lower track, can plant transplanting object attractive in appearancely.
In addition, utilize a crank arm 85 that the link mechanism of the parallel shape being made up of upper arm 82, lower-left arm 83 and bottom right arm 97 of cultivation device 19 is moved.Because the crank arm 85 with an axle drives, therefore 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 that uses 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 being configured in than the middle position of the length direction of left back swing arm 81 near the position of upper rear axle 90, near on the position of the oscillating cam driving shaft 88 of the fulcrum of front swing arm 80 with the live-rollers 87 of wobble drive cam 84 butts, therefore can shorten and the distance of the fulcrum of wobble drive cam 84, can dwindle wobble drive cam 84.Owing to can dwindling 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 travelling of having added cigarette seeding transplant machine 10 becomes linearity near lower dead center carries out upper and lower track, can ground attractive in appearance bed out young plants etc. transplants object.Have, it is that toroidal is comparatively desirable that the track 17 that the front end of plantation utensil 28 is described is adjusted in the scope of planting depth again.By making to plant the quiet track that utensil 28 is toroidal in the scope of charging in soil, thereby can reduce to plant hole.
In addition, by track 17 shape that width diminishes before and after than the top side of planting depth place being that the front end of planting utensil 28 is described, thereby can strengthen plantation utensil 28 amount of movement to front side while rising, the front end of plantation utensil 28 can not be suspended to the rice shoot of having planted etc.
In addition, due to utilize extension spring 167 to left back swing arm 81 to the power of lifting to oblique front upper place, therefore can prevent that plantation utensil 28 is sharply fallen and caused the responsiveness of the utensil of the plantation on track 17 28 improper because of the deadweight of plantation utensil 28 in the time that plantation utensil 28 declines to 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, therefore can make to plant utensil 28 and stably move.
In addition, by crank arm 85 is rotated counterclockwise among the Figure 18 observing from right side side, crank arm 85 to opposite spin, therefore easily makes to plant near the translational speed of utensil 28 top dead centre of track 17 slack-off with respect to the ring-type track 17 that moves of plantation utensil 28.Slack-off by making to plant near the translational speed of utensil 28 top dead centre, 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 right back swing arm 99 direction rear action in the past, but the rotation connection shaft 106 of the front end of crank arm 85 forwards rotates from rear.Move to ground because front swing arm 80, left back swing arm 81 and right back swing arm 99 are relative with crank arm 85, the speed moving up and down that therefore can make to plant utensil 28 is slack-off, even if the spacing in the rows of plantation changes, the variation of the moving track of plantation utensil 28 front ends in the soil travelling of having added body is also little.
In addition, near lower dead center, due to crank arm 85 and armite 86 in the vertical direction or close in the direction of vertical direction point-blank, what crank arm 85 carried out move up and down with armite 86 be formed slopely move up and down unanimously, therefore 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, that is undertaken by crank arm 85 and armite 86 moves up and down, and can make to plant utensil 28 and more promptly rise.
Figure 24 is the figure of the allocation position of the each driving shaft in explanation cultivation device driving box 27, represents the figure observing 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 the upper rear axle 90 that left and right connects cultivation device driving box 27 is configured in than on the center of link oscillating cam driving shaft 88 and crank arm driving shaft 89 straight line each other position on the lower.
The driving force of transmitting to cultivation device driving box 27 from plantation transmission case 26 is passed to oscillating cam driving shaft 88.And in cultivation device driving box 27, by driving-chain 107, the driving force of oscillating cam driving shaft 88 is also delivered to crank arm driving shaft 89.

In addition, on the top of left side cantilever web 66, be formed with the left side long slot bore 168 of the other end part of the cantilever lever portion 63 that links cantilever 50.
As shown in Figure 40 and Figure 41, in one end of hydraulic stem 55, with the rectangular direction of length direction of hydraulic stem 55 on be provided with and link pillar connecting axle 75, at the other end, be formed with the rotation post connect apertures 76 linking 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 associated with cantilever 50.
Link pillar circular shaft part 61 bending shaft portion, side is observed and the shaft portion that links 60 one-tenth V-shapes of pillar board, inserts the cantilever shaft sleeve part 64 of cantilever 50, cantilever 50 can sliding axially at link pillar circular shaft part 61.In addition, the left side long slot bore 168 of the both ends of the cantilever lever portion 63 of cantilever 50 and left side earthing position detection body 36 and the right side long slot bore 173 of right side earthing position detection body 37 link, and end separately can be in these long slot bore 168,173 interior movements.
The the second grounding body turning cylinder 52 extending to the left and right directions of body is fixed on left side grounding body support bar 54, in addition, the shaft portion that becomes the turning cylinder that links pillar circular shaft part 61 with the coaxial position of the second grounding body turning cylinder 52 on rotate the earth's axis freely and be supported on right side grounding body support bar 59, left side earthing position detection body 36, right side earthing position detection body 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 the rotation post axle 58 on main frame 22.With regard to hydraulic stem 55, the link pillar connecting axle 75 that is arranged on one end links with the hydraulic stem linking part 62 that cantilever links pillar 51, by being formed at the rotation post connect apertures 76 of the other end and one end of rotation post 56 links.
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 portion 24 link.In addition the intermediate linking part linking by the formations such as hydraulic stem 55, rotation post 56 and connecting rod 57 and hydraulic switch valve portion 24.
By moving up and down of connecting rod 57, hydraulic lifting cylinder 23 moves with switching valve by means of the elevating control being equipped with in hydraulic switch valve portion 24,14 liftings of left and right trailing wheel.
Secondly, the action of the mechanism that is certain altitude by the height control of body is described.In the time of the plantation operation of carrying out rice shoot, if ridge U upper surface approaches body, 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, left side earth plate 65 and right side earth plate 70 decline along ridge U upper surface.
Here, approach body about ridge U upper surface, the state that left side earth plate 65 and right side earth plate 70 are lifted describes.
In Figure 35, if left side earth plate 65 and right side earth plate 70 are lifted, left side earthing position detection body 36 and right side earthing position detection body 37 are rotated to counter clockwise direction by the second grounding body turning cylinder 52 coaxial on left and right directions and centered by linking pillar circular shaft part 61.
If left side earthing position detection body 36 and right side earthing position detection body 37 are to counterclockwise rotating, the cantilever lever portion 63 two ends being coordinated with left side long slot bore 168 and right side long slot bore 173 applies to the power in body front, by cantilever 50 is applied to the power in body front, thereby the link pillar circular shaft part 61 that connects cantilever shaft sleeve part 64 is applied to the power in body front, and cantilever links pillar 51 and rotates to counter clockwise direction centered by being configured in the link pillar circular shaft part 61 on left and right directions.
If cantilever links pillar 51 to counterclockwise rotating, apply the power that hydraulic stem 55 is moved to body front, the rotation post 56 linking 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 linking with the other end of rotation post 56 is moved upward.
If connecting rod 57 is moved upward, the hydraulic switch valve portion 24 linking with the other end of connecting rod 57 moves hydraulic lifting cylinder 23 by elevating control with switching valve, thereby left and right trailing wheel 14 declines.
Decline by left and right trailing wheel 14, body rises with respect to ridge U upper surface, the distance of body and ridge U upper surface can be remained to certain distance.
In the time of the plantation operation of carrying out rice shoot, at ridge U upper surface away from body in the situation that, left side earth plate 65 and right side earth plate 70 decline along ridge U upper surface, in Figure 35, left side earthing position detection body 36 and right side earthing position detection body 37 are rotated to clockwise direction, and the above-mentioned situation that approaches body with ridge U upper surface is moved on the contrary.Namely, this occasion, connecting rod 57 moves downwards, and hydraulic switch valve portion 24 moves hydraulic lifting cylinder 23 by elevating control with switching valve, makes left and right trailing wheel 14 increase., in this case, body declines 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, approach body or during away from body, the distance of body and ridge U upper surface all remains certain distance at ridge U upper surface, therefore the plantation of rice shoot can not crossed dark or excessively shallow.
In addition, left side grounding body support bar 54 and right side grounding body support bar 59 are arranged on and are fixed on body and are configured on the frame supported axle 73 on left and right directions, become one and can be centered by frame supported axle 73 and rotate with planting depth bar 53.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., form planting depth and 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 body 36 and right side earthing position detection body 37, therefore can, according to the planting depth of plantation object, regulate the certain distance between body and ridge U upper surface.
In addition, as shown in Figure 35 and 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 rear end is fixed on the right side extension spring 69 on 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 body 37 is applied to the active force clockwise rotating.The load that tangles the front end of right side extension spring 69 by change specifies the position in hole 74, thereby the active force being applied in right side earthing position detection body 37 is changed.Namely, specify the position in hole 74 according to the load of front end that tangles right side extension spring 69, can regulate the ground connection load of right side earthing position detection body 37 to farmland.And along with the adjusting of the ground connection load of right side earthing position detection body 37, the control sensitivity of elevating control changes.
For left side earthing position detection body 36 too, on the top, rear of left side cantilever web 66, longitudinally be formed with side by side three load regulation holes 74, the front end that 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 that can regulate the ground connection load of left side earthing position detection body 36 to farmland.
Then, illustrate there is the reasons such as soil block because farmland is coarse, action when only a side of left side earthing position detection body 36 and right side earthing position detection body 37 detects the variation of the distance from body to ridge U upper surface.
, 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 situation there is soil block on the ridge U of right side earth plate 70 sides time.
If there is soil block in the right side of the ridge U contacting at right side earth plate 70, right side earth plate 70 is lifted along this soil block, in Figure 35, only right side earthing position detection body 37 is rotated to counter clockwise direction centered by being configured in the link pillar circular shaft part 61 on left and right directions.
If right side earthing position detection body 37, to counterclockwise rotating, applies to the power in body front one end part of the cantilever lever portion 63 coordinating with the right side long slot bore 173 of right side earthing position detection body 37, cantilever 50 is applied to the power in body front.Now, because left side earthing position detection body 36 is not rotated, therefore another distolateral power that it is forwards moved that applies to the cantilever lever portion 63 coordinating with the left side long slot bore 168 of left side earthing position detection body 36 not.Because the cantilever shaft sleeve part 64 of cantilever 50 is fixed on the middle position at two ends of cantilever lever portion 63, therefore cantilever shaft sleeve part 64 moves a half-distance of the displacement of one end, right side part of cantilever lever portion 63.
Therefore, connecting on the link pillar circular shaft part 61 of cantilever shaft sleeve part 64, applying the power to body front corresponding with a half-distance of the displacement of one end, right side part of cantilever lever portion 63.And according to this power to body front, cantilever links pillar 51 and rotates to counter clockwise direction centered by being configured in the link pillar circular shaft part 61 on left and right directions.
If cantilever links pillar 51 to counterclockwise rotating, hydraulic stem 55 is applied to the power moving to body front, the rotation post 56 linking 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 linking with the other end of rotation post 56 is moved upward.The amount of movement upward of connecting rod 57 is now the amount of movement corresponding with a half-distance of the displacement of one end, right side part of cantilever lever portion 63.
According to connecting rod 57 amount of movement upward, the hydraulic switch valve portion 24 linking with the other end of connecting rod 57 moves hydraulic lifting cylinder 23 by elevating control with switching valve, and by left and right trailing wheel 14 is declined, body rises with respect to ridge U upper surface.
Now, body with respect to ridge U upper surface rise amount of movement be, the half of the converted quantity of the ridge U close to above-below direction being detected by left side earthing position detection body 36.
In the link gear that is certain altitude by the height control of the body of present embodiment, corresponding to the variable quantity part after the variable quantity equalization moving up and down that detected separately by left side earthing position detection body 36 and right side earthing position detection body 37, control the lifting of body body.Because detecting farmland face, the detection equalization that two left side earthing position detection bodies 36 of left and right configuration and right side earthing position detection body 37 are carried out detects, even if therefore there is soil block on the U of ridge, body also can not change significantly up and down, but carry out stable elevating control, can realize suitableization of elevating control.
In addition, as shown in figure 35, the link gear that is certain altitude by the body height control of present embodiment adopts following structure: by left side earthing position detection body 36 and right side earthing position detection body 37, by linking cantilever 50 than left side long slot bore 168 and the right side long slot bore 173 of their turning cylinder 52,61 top location, the position correspondence left side earthing position detection body 36 of cantilever 50 and the position moving up and down of right side earthing position detection body 37 change.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 portion 63 linking with left side earthing position detection body 36 and right side earthing position detection body 37, than turning cylinder 52,61 top sides' position, cantilever links pillar 51 and is attached on hydraulic stem 55, therefore becomes small-sized structure as link gear entirety.
In addition, as shown in figure 35, while observation in side, the position configuration that the cantilever linking with left side earthing position detection body 36 and right side earthing position detection body 37 links pillar 51 and one 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 moves and the structure that the body that travels is maintained left and right horizontal is illustrated with hydraulic cylinder 25, but be not limited thereto, also can make and for example not possess the sensor of tilting 42, but possess the structure of operator with the rotary regulating lever of the manual manual type of controlling the use hydraulic cylinder 25 that tilts itself.
Figure 45 is the approximate vertical view of the rotary regulating lever of a variation of the cigarette seeding transplant machine 10 in explanation present embodiment.
In addition, Figure 46 represents the approximate vertical view of rotary regulating lever part, and Figure 47 represents the approximate vertical view tilting by switching valve part.
In the cigarette seeding transplant machine 10 shown in Figure 45, rotary regulating lever 47 is arranged on while controlling control crank 16 can be by the part of the maneuverable control crank 16 of left hand.
Rotary regulating lever 47 with tilt with switching valve 46 by inclination use regulate cable 48 be connected.In addition,, in Figure 45, omitted and tilted by the diagram that regulates cable 48.
The action bars portion 127 that rotary regulating lever 47 is used by manual operation and midway forming to the adjusting arm 128 of right angle orientation extension from action bars portion 127.Be arranged on the dwang fulcrum 126 of the rotating fulcrum portion that becomes on control crank 16, rotate earth's axis support operation bar portion 127 freely with the part that regulates arm 128 to link.
In action bars portion 127, be connected with the neutral retracting spring 125 that one end is fixed on control crank 16 with the end of a manual side opposition side, become the structure being stretched by neutral retracting spring 125.After action bars portion 127 being operated with hand, if hand is left to action bars portion 127, rotary regulating lever 47 returns to the neutral position of not carrying out tilt operation by the active force of neutral retracting spring 125.
Link to tilt with the one end that regulates cable 48 at the front end that regulates arm 128.By use hand rotating operation bar portion 127 centered by dwang fulcrum 126, thereby regulate the front end of arm 128 also to rotate, follow in this, tilt with regulating cable 48 to move in the longitudinal direction.And this inclination is passed to tilt with regulating another of cable 48 distolateral with the amount of movement of length direction that regulates cable 48.
In addition,, when rotary regulating lever 47 is neutral condition, be configured to parallel with the direction of the length direction of action bars portion 127 with the direction of one end part that regulates the inclination that links of arm 128 adjusting cable 48.By this configuration, can prevent from regulating the stained of cable 48.In addition, owing to regulating arm 128 to meet at right angles taking action bars portion 127 as baseline configuration, therefore, by this configuration, can receive compactly rotary regulating lever 47.
