And seedling host body 22 is examples for host body of the present invention, seedling accepting unit 25 is examples for section of the present invention.

Next details from the action of seedling to each transplanting device 20 that, the seedling feedway 6 from present embodiment is supplied with to describes.

Shown in Figure 21 (a), respectively fall supply with position 31a～31d and and their position relationships between corresponding transplanting device 20 respectively, the left side view of the 1st seedling guiding piece 32a shown in Figure 21 (b), the left side view of the 2nd seedling guiding piece 32b shown in Figure 21 (c) and the 3rd seedling guiding piece 32c, the left side view of the 4th seedling guiding piece 32d shown in Figure 20 (d).

In order to make to fall and the seedling supplied with is supplied with reliably from seedling host body 22, the seedling guiding piece 32a～32d of the shape of open side expansion is upward installed on the top of each transplanting device 20.In Figure 21 (a), omit the diagram of the main part of each transplanting device 20, and recorded the part of the 1st seedling guiding piece 32a, the 2nd seedling guiding piece 32b, the 3rd seedling guiding piece 32c and the 4th seedling guiding piece 32d that install on each transplanting device 20 top separately.

And, as shown in (a)～Figure 21 of Figure 21 (d), using the opening of the upper end side of the 1st seedling guiding piece 32a as the 1st seedling input port 32a1, using the opening of the upper end side of the 2nd seedling guiding piece 32b as the 2nd seedling input port 32b1, using the opening of the upper end side of the 3rd seedling guiding piece 32c as the 3rd seedling input port 32c1, using the opening of the upper end side of the 4th seedling guiding piece 32d as the 4th seedling input port 32d1.And, using the opening of the lower end side of the 1st seedling guiding piece 32a as the 1st seedling supply port 32a2, using the opening of the lower end side of the 2nd seedling guiding piece 32b as the 2nd seedling supply port 32b2, using the opening of the lower end side of the 3rd seedling guiding piece 32c as the 3rd seedling supply port 32c2, using the opening of the lower end side of the 4th seedling guiding piece 32d as the 4th seedling supply port 32d2.

In addition, further narrate in the back for the structure of each seedling guiding piece.

Figure 18 illustrates the state while making seedling fall and be supplied to the 2nd transplanting device corresponding with left several the 2nd row from seedling host body 22.

At this moment, the 2nd transplanting device moving up and down arrives near top dead-centre, and the 1st transplanting device synchronously moving up and down with the 2nd transplanting device also arrives near top dead-centre.

At this moment, as shown in figure 18, the seedling host body 22 of distinguishing with number 1 of having accommodated the seedling that should supply with to the 1st transplanting device moves to the position being offset to the right than the top of the 1st transplanting device.Therefore, at this moment, when seedling is supplied to the moment of the 2nd transplanting device, use the bottom 27 of the seedling host body 22 that number 1 distinguishes open, seedling also can drop to the position of departing to the right from the 1st seedling guiding piece 32a of the 1st transplanting device, thereby seedling cannot be supplied to the 1st transplanting device.

In addition, at this moment, as shown in figure 18, the seedling host body 22 of distinguishing with number 2 of having accommodated the seedling that should supply with to the 2nd transplanting device is positioned at the top of the 2nd transplanting device.Therefore, in this moment, by the bottom of the seedling host body 22 of distinguishing with number 2 27 is opened, seedling drops to the position of the 2nd seedling input port 32b1 of the 2nd seedling guiding piece 32b of the 2nd transplanting device, and then seedling is supplied to the 2nd transplanting device from the 2nd seedling supply port 32b2 reliably.

In the present embodiment, at this moment, in order to make reliably seedling fall and to be supplied to the 1st transplanting device, and be configured in the Zao moment in the moment that is fed into the 2nd transplanting device than seedling, seedling is supplied to the 1st transplanting device.

; not in the time that the 1st transplanting device arrives near top dead-centre, to make the bottom 27 of seedling host body 22 open; but than arrive near moment top dead-centre Zao, moment that the 1st transplanting device moves up towards top dead-centre on movement locus A, make bottom 27 openings of seedling host body 22.

That is to say, in this open moment of bottom 27, the 1st transplanting device is positioned at the region that moves up of movement locus A, and is positioned at the position that the ratio top dead-centre of movement locus A is offset rearward.Therefore, it is consistent that the front and back position and the 1st of the 1st transplanting device when falling of seedling supplied with falls the front and back position of supply position 31a, and the 1st transplanting device is positioned at take the 2nd transplanting device and the 3rd transplanting device as the benchmark position that forwards side staggers.

In addition, specifically, by regulating the position of the part of the interruption of the host body bolster 52 that the seedling host body 22 of distinguishing by sequence number 1 is supported on around path, can freely regulate the open moment of the bottom 27 of seedling host body 22.

According to this structure, in the time that the seedling host body 22 of distinguishing with number 1 is come the top of the 1st transplanting device, can make the seedling that is contained in seedling host body 22 fall, therefore, can reliably seedling be supplied to the 1st transplanting device.

And, the time point of being opened at the bottom 27 of seedling host body 22, the position of the 1st transplanting device is offset rearward than the top dead-centre of movement locus A, to this, by make the 1st transplanting device take the 2nd transplanting device and the 3rd transplanting device as benchmark forwards side stagger, can reliably seedling be supplied to the 1st transplanting device.

On the other hand, in order to make reliably seedling fall and to be supplied to the 4th transplanting device, make seedling be supplied to the 4th transplanting device and be configured in the slow moment in moment that is fed into the 3rd transplanting device than seedling.

Figure 22 illustrates seedling is fallen and the figure describing is moved in the supply of seedling state, that seedling is fallen to feed mechanism 24 while being supplied to the 3rd transplanting device corresponding with left several the 3rd row from seedling host body 22, is the schematic diagram of observing seedling feedway 6 from top.

The 3rd transplanting device and the 4th transplanting device move up and down with the phase place that differs 180 degree with respect to the 1st transplanting device and the 2nd transplanting device, therefore, from the state shown in Figure 18, seedling host body 22 moves while being equivalent to the amount of 2 seedling host bodies 22 on around path, the 3rd transplanting device moving up and down and the 4th transplanting device arrive near top dead-centre, become the state shown in Figure 22.

In the time supplying with seedling from seedling host body 22 to the 3rd transplanting device, the 3rd transplanting device arrives near top dead-centre, and the 4th transplanting device synchronously moving up and down with the 3rd transplanting device also reaches near top dead-centre.

At this moment, as shown in figure 22, the seedling host body 22 of distinguishing with number 4 of having accommodated the seedling that should supply with to the 4th transplanting device only moves to the position being offset to the left than the top of the 4th transplanting device.Therefore, at this moment, in supplying with moment of seedling to the 3rd transplanting device, use the bottom 27 of the seedling host body 22 that number 4 distinguishes open, seedling is also to drop to the position of departing to the left from the 4th seedling guiding piece 32d of the 4th transplanting device, seedling cannot be supplied to the 4th transplanting device.

In addition, at this moment, as shown in figure 22, the seedling host body 22 of distinguishing with number 3 of having accommodated the seedling that should supply with to the 3rd transplanting device is positioned at the top of the 3rd transplanting device.Therefore, in this moment, by the bottom of the seedling host body 22 of distinguishing with number 3 27 is opened, seedling drops to the position of the 3rd seedling input port 32c1 of the 3rd seedling guiding piece 32c of the 3rd transplanting device, and then seedling is supplied to the 3rd transplanting device from the 3rd seedling supply port 32c2 reliably.

In the present embodiment, at this moment, in order to make reliably seedling fall and to be supplied to the 4th transplanting device, make seedling be supplied to the 4th transplanting device and be configured in the slow moment in moment that is fed into the 3rd transplanting device than seedling.

, be not in the time that the 4th transplanting device arrives near top dead-centre, to make the bottom 27 of seedling host body 22 open, but the moment that starts to move down through top dead-centre at the 4th transplanting device on movement locus A make the bottom 27 of seedling host body 22 open.

That is to say, this time point of being opened at bottom 27, the 4th transplanting device is positioned at the region that moves down of movement locus A, and is positioned at the position that the ratio top dead-centre of movement locus A is offset rearward.Therefore, it is consistent that the front and back position and the 4th of the 4th transplanting device when falling of seedling supplied with falls the front and back position of supply position 31d, and the 4th transplanting device is positioned at take the 2nd transplanting device and the 3rd transplanting device as the benchmark position that forwards side staggers.

In addition, specifically, by regulating the position of the part of the interruption of the host body bolster 52 that the seedling host body 22 of distinguishing with number 4 is supported on around path, can freely regulate the open moment of the bottom 27 of seedling host body 22.

According to this structure, in the time that the seedling host body 22 of distinguishing with number 4 is come the top of the 4th transplanting device, can make the seedling that is contained in seedling host body 22 fall, therefore, can reliably seedling be supplied to the 4th transplanting device.

And, the time point of being opened at the bottom 27 of seedling host body 22, the position of the 4th transplanting device is offset rearward than the top dead-centre of movement locus A, to this, by make the 4th transplanting device take the 2nd transplanting device and the 3rd transplanting device as benchmark forwards side stagger, can reliably seedling be supplied to the 4th transplanting device.

And, according to this structure, 4 row can be set for uniformly-spaced, and be made linearity part 28 longer, therefore can be disposed at this around mobile route with common around mobile route and by multiple seedling host bodies 22 in 4 enforcements, replenishment operation improves.And linearity part 28 is longer owing to making, so can reduce the front and back width of seedling feedway 6, realize the densification of body.

And, on seedling being supplied in than the 1st transplanting device of top dead-centre position on the lower and the 4th transplanting device this point, existence is fallen and supplies with the of the present invention upper movement of destabilizing factor and fall and supply with position (the 1st fall supply with position 31a) and lower movement and fall the position of supplying with position (the 4th falls supply position 31d) and be configured in two ends, left and right, thus, the confirmation that falls supply condition of the seedling of these positions becomes easy.

As shown in Figure 21 (a), be installed on the 1st seedling guiding piece 32a of the 1st transplanting device and the 4th transplanting device and the 4th seedling guiding piece 32d and be formed as top than the shape that is installed on the 2nd seedling guiding piece 32b of the 2nd transplanting device and the 3rd transplanting device and the top of the 3rd seedling guiding piece 32c and expands greatlyr at left and right directions.

And as shown in (b)～Figure 21 of Figure 18, Figure 21 (d), the position of the 1st seedling input port 32a1 of the 1st seedling guiding piece 32a is the front and back position identical with the position of the 1st seedling supply port 32a2 overlooking under observation.And the position of the 4th seedling input port 32d1 of the 4th seedling guiding piece 32d is the front and back position identical with the position of the 4th seedling supply port 32d2 overlooking under observation.And, the position of the 2nd seedling input port 32b1 of the 2nd seedling guiding piece 32b overlook under observation identical with the position of the 2nd seedling supply port 32b2.And, the position of the 3rd seedling input port 32c1 of the 3rd seedling guiding piece 32c overlook under observation identical with the position of the 3rd seedling supply port 32c2.

According to this structure, can make from than directly over the 1st transplanting device and the 4th transplanting device to the left and right direction be slightly offset the 1st fall and supply with position 31a and the 4th and fall and supply with position 31d fallen seedling and be supplied to reliably the 1st transplanting device and the 4th transplanting device.

And, be the large shape of width that top is widened at left and right directions by making the 1st seedling guiding piece 32a and the 4th seedling guiding piece 32d, can tackle the skew of the left and right directions of the fallen position of seedling, therefore, can will make seedling fall and supply with position 31a and the 4th and fall and supply with the moment of moment of falling of position 31d when being set as the 1st transplanting device and the 4th transplanting device and coming the position of more close top dead-centre from the 1st.Seedling is fallen supply with, can more reliably seedling be supplied to the 1st transplanting device and the 4th transplanting device by come the moment of the position of more close top dead-centre at the 1st transplanting device and the 4th transplanting device.And, can suppress the amount of moving left and right of the seedling being supplied to being caused by the 1st seedling guiding piece 32a and the 4th seedling guiding piece 32d, can carry out swimmingly the supply that falls of seedling.

And the 1st transplanting device of present embodiment and the 4th transplanting device can be in left and right directions shift positions, thus, can be with simple structure modify transplanting line spacing.

Even when moved the 1st transplanting device and the 4th transplanting device along left and right directions, also can utilize said method to regulate seedling to leave the moment behind to the confession of the 1st transplanting device and the 4th transplanting device, thereby seedling is fallen reliably and be supplied to the 1st transplanting device and the 4th transplanting device.

As other example, the seedling feedway of the seeding transplant machine to 3 row transplantings describes, this seeding transplant machine has the structure that three transplanting devices move up and down respectively to differ the phase place of 120 degree, in illustrated example, show and make seedling fall and be supplied to the state when hitting exactly transplanting device 20 corresponding to row from seedling host body 22.

For the transplanting device 20 corresponding with left row, the moment that starts to decline through top dead-centre at the transplanting device 20 moving up and down makes seedling supply with from seedling host body 22, for the transplanting device 20 corresponding with right side row, in the moment slightly forward, that move up towards top dead-centre that moves up and down transplanting device 20 and arrive top dead-centre, seedling is supplied with from seedling host body 22, thus, seedling can be fallen reliably and be supplied to each transplanting device 20.

In addition, in the seeding transplant machine of 3 row transplantings, seedling is fallen being supplied in the position of the capable transplanting device 20 that carries out transplanting in center is that top dead-centre falls an example of supplying with position, seedling being fallen be supplied to the position of carrying out the transplanting device 20 of transplanting in left row is that lower movement falls an example of supplying with position, the position that seedling is fallen be supplied to carry out the transplanting device 20 of transplanting at right side row be of the present invention the mobile example of supplying with position that falls.

(line spacing adjusting)

Next, regulate counter structure to describe to the line spacing of transplanting portion, as shown shown in exploded perspective Figure 27 of example (a), be the assembling point 20a of transplanting device 20 for grafting device, be configured to the adjusting that can tilt, and be folded with the linking part 41 being formed by support 41a and slotted hole parts 41b between the covering device frame 39 of the frame structure arranged side by side of the suppression of soil of about supporting wheel 37 and bar 40.In addition, be configured to and utilize bar 40 to guide moving up and down of covering device frame 39, prevent position, the left and right skew of the rearward end of covering device frame 39.
