In addition, as shown in figure 22, at roller 147 on the path of rolling on the guide rail 139, with peristome (or otch) 139R, be arranged on the toe lateral of guide rail 139 of body upper to the 139L mutual dislocation.And, as shown in Figure 21, in the face of peristome 139R, the steel wire of the shape of 139L (piano wire) extends towards inclined-plane 336L (336R) side, its part forms towards oblique below, make installation base portion (BM) displacement of above-mentioned steel wire B (piano wire) or leaf spring (BT), so that the end of steel wire B (piano wire) or leaf spring (BT) its when opening with above-mentioned shield 145 is vertical downwards carried the planar portions 145a butt of rotation direction rear side, and it is stopped on the position that side-sway returns backward, base portion BM is installed installs towards left-handed opening guide portion 340 and right switch guide portion 341 sides ground from guide rail 139 by linking parts (bolt etc.) N on left and right directions adjusting ground up and down.
Like this, though be provided with two transplanting in the present embodiment, also can pass through the quantity of the roller 147 of increase shield 145, the path of the guide rail 139 that passes through with each roller 147 cut accordingly guide rail 139 counterpart, set the release position of shield 145 etc., with this quantity of setting up shield 145 and transplanting hole making drill 151, increase the bar number of transplanting.In addition, also be provided as simultaneously forcibly steel wire B or the leaf spring (BT) of shield 145 to the augmentor of pushing as the below of seedling supply side, its effect also is identical thereupon.
Utilize Figure 23, one side carries the operating state of body 150 to describe with regard to seedling, and one side is with regard to shield 145 with as describing to the effect to steel wire B of the augmentor of reinforcing (piano wire) or the leaf spring wideer than steel wire of the evolution of this shield 145.
The chimeric ring 158 that the body of base portion 140 is installed as tube is cylindrical shells, and seedling transport tube 148 is also formed by cylindrical shell, and the seedling conveying body 150 that both are constituted also is a cylindrical shell.On seedling transport tube 148, though what illustrate is the state that seedling 126 is inserted into, under the actual job state, seedling falls to transplanting portion 120 from illustrated seedling transport tube 148.The seedling transport tube 148 that is inserted with this seedling that falls 126 is carried to arrow H direction.The shield 145 of this moment is assumed to be shield 145A.Move along inclined-plane 336L (336R) one side that rises by roller 147 one side, become the shield 145B of next state, close seedling transport tube 148 the bottom, etc. be inserted into next seedling 126.Represent the state that further moves to the right side of figure with shield 145D.
Represent state before next seedling 126 is inserted into, arrives at once when overlooking transplanting hole making drill 151 position overlapped with corresponding transplanting portion 120 with identical symbol 145D.In case arrive the peristome 139L (139R) of guide rail 139, then the planar portions of the roller installation portion 145c of shield 145 to the reinforcing of oblique below, is utilized the deadweight of shield 145 by steel wire (piano wire) B then, is that fulcrum is opened with fulcrum pin 146.This moment, seedling 126 as one man fell with seedling transplanting 151 times of hole making drill of seedling transplanting portion 120.
At this moment, because deadweight inertia plays a role, shield 145 is swung, and therefore in order not destroy the posture of seedling full state, the top ends of steel wire B (leaf spring BT) and the planar portions 145a butt of shield 145 suppress it and put back.The shield of representing this moment with symbol 145E.And, since transplant 145 two of hole making drill 151 and shields respectively simultaneously the time as one man carry out, therefore two seedlings 126 are supplied with simultaneously.
At this moment, above-mentioned steel wire B and leaf spring BT are configured such that dislocation before and after the installation site respectively, square to the inside displacement respectively when site of action is overlooked.
That is, be not used in the parts of backing roll 147 on above-mentioned peristome 139R, 139L, in case shield 145 is that rotate downwards at the center with fulcrum pin 146, then tube is installed the lower opening of base portion 140, and seedling 126 falls to transplanting portion 120.
As shown in figure 18, peristome 139R, 139L are respectively the seedling lowering positions in the seedling supply unit 107, transplant hole making drill 151,151 and are arranged on this seedling lowering position with the overlapping form of plane apparent time respectively.
The seedling that the seedling that above-mentioned a plurality of seedling carries body 150 to be fallen by the peristome 139L that makes seedling 126 from the left side is carried 150 groups of bodies (seedling of planting usefulness hereinafter referred to as moving to left is carried 150 groups of bodies) and seedling 126 is fallen from the peristome 139R on right side is carried two groups of formations of 150 groups of the bodies seedling conveying body of usefulness (plant hereinafter referred to as moving to right 150 groups).
And, carrying the arranged outside of the circulating path that body 150 moves to have the seedling of roller 147 to carry the set of body 150 at seedling is that the seedling of planting usefulness that moves to left is carried 150 groups of bodies, and it is that the seedling of planting usefulness that moves to right is carried 150 groups of bodies that the seedling that is provided with roller 147 in the inboard of this circulating path is carried the set of body 150.As mentioned above, because each seedling carries body (move to left plant usefulness, move to right and plant usefulness) 150 seedling 126 being moved on on the position of transplanting hole making drill 151, shield 145 is opening downwards simultaneously, and therefore, falling posture does not have destroyedly, can expect to improve the precision of transplanting operation.
At this, be elaborated with regard to the structure of guide rail 139.(this situation is the embodiment of two of plantations)
As shown in figure 22, guide rail 139 is installed the overlapping mode of the mobile circulating path of base portion 140 with tube when overlooking and is formed Long Circle.
In addition, on left-handed opening guide portion 340, the position beyond the open guide portion 340a be roller 147 close guide portion 340b.Closing on the guide portion 340b, the seedling of planting usefulness that moves to left carries the roller 147 of body 150 not fall, and shield 145 is maintained at closed condition, carries out carrying the seedling of body 150 to carry based on this seedling.
That is, left-handed opening guide portion 340 is made of with the open guide portion 340a that this roller 147 falls the guide portion 340b that closes of the face of roller 147 rotations of the seedling conveying body 150 of planting usefulness as moving to left.
Equally, right switch guide portion 341 also carries the open guide portion 341a that guide portion 341b and this roller 147 fall that closes of face that the roller 147 of body 150 rotates to constitute by the seedling of planting usefulness as moving to right.
Sum up foregoing.On the oblong guide rail 139 of the length of left and right directions, peristome 139R, 139L are along above-mentioned circulating path opening.The floor space that this peristome 139R, 139L install base portion 140 greater than tube is formed for open shield 145 so that either party of open guide portion 340a, the 341a that seedling 126 can fall.Specifically be, with respect to throughput direction, a side about a side, the opposing party form big opening so that roller 147 falls to position consistency respectively at left and right sides opposite side in the side, though the degree that a side that is not positioned at roller 147 is installed the bottom surface of base portion 140 less times greater than tube makes seedling 126 fall (shield 145 can rotate) downwards, be attached to the roller 147 that the tube of adjacency is installed on the base portion 140 before and after the direction of advance and can not fall into.That is peristome 139R, the 139L throughput direction center line ground of the opposition side expansion to the left and right opening mutually of base portion 140 being installed with respect to tube.
In addition, peristome 139R, 139L install the position opening of 140 3 spacings of base portion or five spacings with respect to throughput direction (circulating path) at the tube that leaves binding, and this spacing wide with bar (stripe pitch) is consistent.
And, on the position that the roller 147 of the direction of advance end side in peristome 139R, 139L passes through, inclined-plane (inclined plane) 336L, the 336R that rise, link with roller 147 rolling surfaces of guide rail 139 are set respectively gradually.The incline direction of inclined- plane 336L, 336R with respect to throughput direction before high back low, along with roller 147 moves in the clear, shield 145 is closed gradually.
The switch of shield 145 is suppressed, forcibly opens by reinforcing by steel wire (piano wire) B or the leaf spring BT of the planar portions reinforcing of pair roller 147, and carries out according to have or not (the opening having or not of guide portion 340a, 341a) with guide rails 139 these roller 147 butts roller 147 belows.In addition, shield 145 is under the state of opening, though because the weight of shield 145 self, on the part that does not have guide rail 139, because inertia is swung, but prevents to put back by the top of above-mentioned steel wire (piano wire) B or leaf spring BT and the planar portions 145a butt of shield 145.Have under the situation that shield 145 puts back, the shield 145 of this swing is interfered with the seedling 126 that is falling sometimes, what make seedling falls the posture disorder, but owing to steel wire B or leaf spring BT and planar portions 145a butt, prevent this pendulum time, therefore, when handing-over seedling 126 in transplanting hole making drill 151, can under the not disorderly state of posture, supply with.Especially, on shield 145, when closing, utilize roller 147 to be undertaken by inclined-plane 336L (perhaps inclined-plane 336R) guiding from opening into.Because the construction of switch of this shield 145 is above-mentioned forms, therefore, as mentioned above, by with front side, the pivot suspension position of shield 145, during with inclined-plane 336L (perhaps inclined-plane 336R) butt, must rotate to closing direction at shield 145 as throughput direction.
So, seedling carries body 150 to be configured to Long Circle on seedling supply unit 107, and each seedling is carried body 150 front of being positioned at of main operating personnel and the less important work personnel by the fuselage rear successively, by the time, seedling 126 is inserted in the seedling transport tube 148.Seedling carry body 150 along oblong circulating path after move the place ahead in this path transplanting portion 120 positions, the roller 147,147 that leaves three spacings is simultaneously owing to being forced to property of the effect ground of steel wire B or leaf spring BT moves downwards with opening, fall in peristome 139R, the 139L as the seedling lowering position, shield 145,145 rotates downwards, opens then.And the seedling 126 that seedling carries body 150 to be kept falls, and is dropped in the transplanting hole making drill 151,151 of transplanting portion 120.
And seedling is carried body 150 in case by the seedling lowering position, then roller 147,147 will be with inclined- plane 336L, 336R butt, rise gradually, shield 145,145 is closed.Like this, carry out the switch of shield 145 with simple structure.
Therefore, seedling is carried body 150 to transplant hole making drill 151 supplies to one alternately from seedling.Promptly, the tube of odd number install base portion 140 about the left side (perhaps right side) of peristome, the tube of even number install base portion 140 on the right side peristome in (perhaps left side), open the shield 145 of below, on the transplanting hole making drill 151,151 of the bar about dropping on according to odd number or even number (and two or three and four).Therefore,, can carry out two transplanting simultaneously by carrying out such operation repeatedly, and can with about the interval of bar remain necessarily.
