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

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

The seedling supplied to make to fall from seedling host body 22 is reliably supplied, and is provided with the seedling guiding piece 32a ~ 32d of the shape of open side expansion upward on the top of each transplanting device 20.In (a) of Figure 21, omit the diagram of the main part of each transplanting device 20, and describe install on the respective top of each transplanting device 20 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 part.

And, as shown in (d) of (a) ~ Figure 21 of Figure 21, 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, the structure for each seedling guiding piece describes later further.

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

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

At this moment, as shown in figure 18, accommodated and should move to the seedling host body 22 of number 1 difference the position offset to the right than the top of the 1st transplanting device to the seedling of the 1st transplanting device supply.Therefore, at this moment, namely while moment seedling being supplied to the 2nd transplanting device, the bottom 27 of the seedling host body 22 namely using number 1 to distinguish is 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, thus seedling cannot be supplied to the 1st transplanting device.

In addition, at this moment, as shown in figure 18, the top being positioned at the 2nd transplanting device with the seedling host body 22 that number 2 is distinguished of the seedling that should supply to the 2nd transplanting device has been accommodated.Therefore, in this moment, open by the bottom 27 of the seedling host body 22 will distinguished with number 2, 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 reliably supplied to the 2nd transplanting device from the 2nd seedling supply port 32b2.

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

Namely, not make the bottom 27 of seedling host body 22 open when the 1st transplanting device arrives near top dead-centre, but when more Zao than the moment arrived near top dead-centre, the 1st transplanting device move up towards top dead-centre on movement locus A, make bottom 27 opening of seedling host body 22.

That is, in this moment that bottom 27 is open, the 1st transplanting device is positioned at the region that moves up of movement locus A, and the position that the ratio top dead-centre being positioned at movement locus A offsets rearward.Therefore, in order to make seedling fall supply time the front and back position and the 1st of the 1st transplanting device to fall the front and back position of supply position 31a consistent, the 1st transplanting device is positioned at the 2nd transplanting device and the 3rd transplanting device for the benchmark forwards position of staggering, side.

In addition, specifically, by the position in the part around interruption path regulated to the host body bolster 52 that the seedling host body 22 distinguished by sequence number 1 supports, the open moment of the bottom 27 of seedling host body 22 can freely be regulated.

According to this structure, when the seedling host body 22 distinguished with number 1 comes the top of the 1st transplanting device, the seedling being contained in seedling host body 22 can be made to fall, therefore, it is possible to reliably seedling is supplied to the 1st transplanting device.

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

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

Figure 22 is the figure that the supply action of seedling that state when making seedling fall from seedling host body 22 and be supplied to the 3rd transplanting device corresponding with left several 3rd row is shown, that seedling is fallen to feed mechanism 24 is described, and is the schematic diagram from top view seedling feedway 6.

3rd transplanting device and the 4th transplanting device move up and down with the phase place differing 180 degree relative to the 1st transplanting device and the 2nd transplanting device, therefore, from the state shown in Figure 18, seedling host body 22 is when being equivalent to the amount of 2 seedling host bodies 22 around movement on path, the 3rd transplanting device moved up and down and the 4th transplanting device arrive near top dead-centre, become the state shown in Figure 22.

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

At this moment, as shown in figure 22, accommodated and should only move to the seedling host body 22 of number 4 difference the position offset to the left than the top of the 4th transplanting device to the seedling of the 4th transplanting device supply.Therefore, at this moment, namely while the moment to the 3rd transplanting device supply seedling, the bottom 27 of the seedling host body 22 namely using number 4 to distinguish is open, seedling is also 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 top being positioned at the 3rd transplanting device with the seedling host body 22 that number 3 is distinguished of the seedling that should supply to the 3rd transplanting device has been accommodated.Therefore, in this moment, open by the bottom 27 of the seedling host body 22 will distinguished with number 3, 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 reliably supplied to the 3rd transplanting device from the 3rd seedling supply port 32c2.

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

That is, not make when the 4th transplanting device arrives near top dead-centre the bottom 27 of seedling host body 22 open, but when the 4th transplanting device starts to move down through top dead-centre on movement locus A, make the bottom 27 of seedling host body 22 open.

That is, at bottom 27 by this time point opened, what the 4th transplanting device was positioned at movement locus A moves down region, and the position that the ratio top dead-centre being positioned at movement locus A offsets rearward.Therefore, in order to make seedling fall supply time the front and back position and the 4th of the 4th transplanting device to fall the front and back position of supply position 31d consistent, the 4th transplanting device is positioned at the 2nd transplanting device and the 3rd transplanting device for the benchmark forwards position of staggering, side.

In addition, specifically, by the position in the part around interruption path regulated to the host body bolster 52 that the seedling host body 22 distinguished with number 4 supports, the open moment of the bottom 27 of seedling host body 22 can freely be regulated.

According to this structure, when the seedling host body 22 distinguished with number 4 comes the top of the 4th transplanting device, the seedling being contained in seedling host body 22 can be made to fall, therefore, it is possible to reliably seedling is supplied to the 4th transplanting device.

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

Further, according to this structure, can be set at equal intervals by 4 row, and make straight section 28 longer, be rotated around path therefore, it is possible to exercise 4 with common being rotated around path and multiple seedling host body 22 is configured at this, replenishment operation improves.Further, due to straight section 28 can be made longer, so the front and back width of seedling feedway 6 can be reduced, the densification of body is achieved.

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

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

Further, as shown in (d) of (b) ~ Figure 21 of Figure 18, Figure 21, 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 under top view.Further, 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 under top view.Further, the position of the 2nd seedling input port 32b1 of the 2nd seedling guiding piece 32b is identical with the position of the 2nd seedling supply port 32b2 under top view.Further, the position of the 3rd seedling input port 32c1 of the 3rd seedling guiding piece 32c is identical with the position of the 3rd seedling supply port 32c2 under top view.

According to this structure, can make to fall the seedling that supply position 31d falls reliably be supplied to the 1st transplanting device and the 4th transplanting device from falling supply position 31a and the 4th than the slightly offset in the lateral direction directly over the 1st transplanting device and the 4th transplanting device the 1st.

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

Further, the 1st transplanting device of present embodiment and the 4th transplanting device can in left and right directions shift positions, thereby, it is possible to simple structure modify transplanting line spacing.

Even if when moving the 1st transplanting device and the 4th transplanting device in left-right direction, said method also can be utilized to regulate seedling to leave the moment behind to the confession of the 1st transplanting device and the 4th transplanting device, thus seedling is reliably fallen and is supplied to the 1st transplanting device and the 4th transplanting device.

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

For the transplanting device 20 corresponding with left row, in the moment that the transplanting device 20 moved up and down starts to decline through top dead-centre, seedling is supplied from seedling host body 22, for the transplanting device 20 corresponding with right side row, move up and down transplanting device 20 arrive top dead-centre slightly by front, towards the moment that top dead-centre moves up, seedling is supplied from seedling host body 22, thereby, it is possible to seedling is reliably fallen and is supplied to each transplanting device 20.

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

(line spacing adjustment)

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