BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape-like seedling transplanting machine constructed by connecting planted seedlings in a tape shape.

[0002]

2. Description of the Related Art Today, when transplanting planted seedlings into a field, a tape-shaped seedling is formed by supporting the transplanted seedlings with a tape material, and the tape-shaped seedlings are transplanted to the planting part (transplantation part). 2. Description of the Related Art There is known a transplanting machine for a tape seedling, which is separated into seedlings destined for a unit planting strain at a time and is planted in a field.

[0003] Among these, for example, those disclosed in Japanese Patent Application Laid-Open Nos. 2-104208 and 2-107108 are known. Is forcibly pulled in and transferred, so that the tape-shaped seedlings are drawn out and conveyed toward the transplanting device side. By the way, in such a thing, when the tape-shaped seedling is, for example, formed by supporting the vicinity of the root of the transplanted seedling with a tape material, when suspended in a suspended state, the tip of the leaf stem portion of the transplanted seedling is inevitably sagged. Easy to go down. However, as is the case with the conventionally known one, in the process from the seedling storage unit to the transfer start end of the seedling feeder, it is inevitable to move in a suspended state, so that the tape-shaped seedling is,
The transplanted seedling is forcibly pulled in while changing its direction to the transport start end of the seedling feeding transporter in a state in which the portion farther from the tape material support position such as the leaf stem tip side or root side is hanging down. . As a result, the hanging part of the transplanted seedling is pulled into the transport start end of the seedling feeding and transporting part with a further delay, and this is one factor that disturbs the seedling attitude of the tape-shaped seedling, and the planting attitude is disturbed, resulting in empty planting or lodging. There is a problem that poor planting of seedlings and the like occurs.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and aims to provide a tape-like seedling transplanting machine capable of eliminating these disadvantages. A seedling storage section for storing a tape-shaped seedling formed by supporting a transplanted seedling with a tape material, and a seedling delivery carrier for feeding and transporting the tape-shaped seedling from the seedling storage section toward the transplant tool side. A tape-type seedling transplanting machine, which transports a seedling part displaced from a tape material position to a tape-type seedling fed from a seedling storage unit at a transport start end of the seedling transporter. It is characterized in that a seedling pull-in body for pulling in to the starting end side is provided.

According to the present invention, the arrangement of the seedlings of the tape-shaped seedlings drawn into the transport start end of the seedling delivery transporter can be avoided as much as possible.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a riding type traveling machine for flooded fields, and a rearward of the traveling machine 1 is a linking mechanism 3 for transplanting a six-row planting plant 2 for transplanting rush seedlings to a field.
It is equipped to be able to move up and down freely through. The transplanting machine 2 is constituted by various member devices such as a body frame 4 having a power transmission mechanism therein, a paddy surface float 5, a transplanting claw 6, a seedling feeder 7, and a seedling mounting table 8. Are as before.

Now, the seedling feeding and transporting body 7 includes a first transporting body 10 for feeding out and transporting the tape-shaped planting seedlings 9 from a seedling mounting table 8 to be described later in a laterally inclined posture, and the planting and feeding seedlings 9. And a second transporting body 11 that transports in the direction of the transplanting nail 6 while gradually rising. Here, tape-shaped seedling 9
In order to prevent the peeling of the tape, the root portion of the seedling or the stem portion in the vicinity thereof is prevented by a tape material 9a such as an adhesive tape (if necessary, the tape material 9a is sewn or wound around with a string or the like). The present embodiment describes a case where the seedlings are supported so as to be sandwiched from both sides, and in this embodiment, the seedlings are continuously supported. good.

The first transporting body 10 includes a root-side transport belt 10a and a pedicle tip-side transport belt 10b opposed to each other at a predetermined interval in the left-right direction. These transport belts 10a, 10b are The transport surface is formed into a concave-convex rib shape, and the transport start end (inclined end) side of a plurality of strip partitioning plates 12 integrally provided at predetermined intervals in the left-right direction on the transport frame 7a. And pulleys 13a, 13b, 14 integrally supported on support shafts 13, 14, respectively, which are horizontally supported on the end (intermediate inclined portion) side.
a, 14b. Further, a pair of spacer rollers 1 is provided between the pulleys 13a and 14a on the transport start end side.
5 and 16 are integrally incorporated. Of these, a plurality of feed claws 15a are protruded from the spacer roller 15 on the tip side of the stem so that the seedlings can be actively pulled (rectified). ing. Of course, if necessary, both spacer rollers 1
Feed claws 5 and 16 may be provided. The spacer rollers 15 and 16 can be integrated with each other. Further, the spacer rollers 15 and 16 can be integrated with the pulleys 13a and 13b, respectively. 15, 16
Can be integrated if necessary. In addition, 1
Numeral 7 is a seedling holding body, and the seedling holding body 17 is a partition plate 12.
Is mounted so as to resiliently swing through a presser press 17a, and the press position is set so as to correspond to the moving position of the tape material 9a.

On the other hand, the second transporting body 11 is disposed so as to be located between the transporting end portions of the transporting belts 10a and 10b. Pulleys 14c respectively provided on horizontal support shafts 18 which are supported by the partition plate 12 at the upper position.
(The pulley 14c is required if the pulleys 14a, 1
4b), and can be integrated with one or both of them.
Pulley 20 provided on support shafts 20 and 21 supported upright
a and a pair of conveyor belts 11a and 11b which are twisted by 90 degrees in the middle of the conveyance process.
At the transfer end portion of the first transfer body 10, a substantially central portion of the transferred tape-like seedling 9 is clamped by a transfer surface in a state in which concavo-convex ribs opposing each other are inconsistently engaged, and gradually erect. Cutting means 22 provided at the end of conveyance
It is designed to be transported toward the side. The cutting means 22 is operated by an intermittent operation mechanism (not shown) which operates in synchronization with the running of the machine body, cuts the tape material 9a at every predetermined position, and converts the unit planted seedlings into the tape-shaped seedlings 9.
To be separated from it. If the tape material 9a is set so as to be cut based on the seedling scraping of the transplant nail 6, or if the tape material 9a is set to be peeled off when scraped by the transplant nail 6, the cutting means 22 is bothersome.
Needless to say, there is no need to provide The planted seedling thus separated is scraped and pinched by the transplanting nail 6 and planted in the field. Further, in carrying out the present invention, the seedling delivery carrier 7 includes the first carrier 1
It is not necessary to divide into the 0 and the second transport bodies 11, and it is of course good that they are formed in a series. Further, the tape-shaped seedling 9 may be raised at the start of transport without raising the tape-like seedling 9 in the middle, or may be raised with a transplanted nail.

The seedling mounting table 8 is for mounting a box-shaped seedling box 23 having an open upper surface, which will be described later. The tape-shaped seedling 9 is folded on the seedling box 23 in a zigzag shape in the front-rear direction. The seedling box 23 is not necessarily limited to a box having only an upper surface as in the embodiment as long as the tape-shaped seedling 9 can be accommodated in a zigzag shape. Instead, an appropriately shaped seedling container, such as one without even an inclined upper side (front) plate, can be adopted if necessary.)
However, the seedling mounting table 8 is disposed with a gap below the first carrier 10. That is, the seedling mounting table 8 is integrally provided on the substantially U-shaped seedling mounting frame 24 provided integrally with the carrier frame 7a and on the working machine stay 2a integrally implanted in the transplanting working machine 2. The base end is integrally supported by the bracket 2b, and the front end (front end) is a seedling mounting frame 2.
Seedling box support 2 consisting of a substantially L-shaped plate supported by 4
5 and a partition plate 12a extending downward from the upper part of the partition plate 12 and partitioning the placement position of the seedling box 23 corresponding to each transplanting strip. The support 25 has a tape-like seedling 9 below the first carrier 10.
In other words, in the embodiment, the seedling box 23 placed in a front-back-to-back-low inclined position is separated downward from the transfer start position of the first transfer body 10 and from the transfer start position. The feeding gap is formed by setting the middle position in the front-rear direction of the seedling box 23 (in the embodiment, it is preferable that the feeding gap can be narrowed toward the center position), and the feeding gap is formed. The feeding path from the seedling box 23 of the seedlings 9 to the transport start end position of the first transporting body 10 is moved forward and backward with respect to the folding direction of the tape-like seedlings 9 of the succeeding stage to be fed out in the folded storage state. It is set so as to be not lifted and moved, but to be lifted upward and separated in a separated state.

Further, reference numeral 26 denotes a detection switch for detecting the absence of seedlings.
5 is mounted on an auxiliary bracket 25a erected on a bracket 2b for mounting and supporting the same on the transplanting machine stay 2b, and a vertically long through-hole formed in a rear plate of the seedling box 23 placed above. 23a.
When the seedling box 23 is placed on the detection switch 26, the switch rod 26 a faces the inside of the through hole 23 a and comes into contact with the folding corner of the tape-shaped seedling 9 that is folded and stored in the zigzag shape in the front-rear direction. The tape-like seedling 9 is consumed and the switch 26a is set.
It is set such that the absence of seedling is detected based on the absence of contact with the seedling. Each of these detection switches 26 is connected in parallel to a detection circuit, and based on detection of absence of any one of the tape-shaped seedlings 9, an alarm 27 is activated and an alarm lamp 28 is turned on. To notify the worker to that effect.

The seedling box 23 can be made of a transparent or translucent resin material whose contents can be seen from the outside through a plate body. Not only the plate but also the front plate is formed in the same way, so that the operator sitting in the driver's seat turns back and can see through each seedling box 23 through this through hole 23a, so that the opaque plate material There is no inconvenience even if configured. In this way, the seedling box 23 has an advantage that the tape-shaped seedlings 9 can be accommodated without being bothered before and after. Furthermore, when a tape-shaped seedling is formed by using a rooted one like a rush seedling, the root side becomes heavy, so when folded and stored in a zigzag shape, the root side becomes thicker and the seedling storage posture becomes thicker. Therefore, as shown in FIG. 7B, the box bottom plate may be inclined so that the root side is deep and the stem tip side is shallow, as shown in FIG.

When the first and second carriers 10 and 11 are driven, power from a drive pulley 29 provided on the body frame 2 is transmitted to the support shafts 14 and 18 via a chain transmission mechanism 30. It is configured to be driven by driving the support shafts 14 and 18.

In the embodiment of the present invention configured as described above, as described above, the tape-shaped seedling 9 folded and stored in the seedling box 23 in a zigzag manner is synchronized with the travel of the machine body by the first carrier 10. Then, the seedlings are cut by the cutting means 22 through the second carrier 11 into the transplanted seedlings destined for the unit planted seedlings, which are transplanted to the field by the transplanting claws 6. The tape-shaped seedling 9 fed out from 23 moves away from the tape-shaped seedling 9 in the subsequent stage to the transport start end side of the first transport body 10 so as to be separated therefrom.

That is, the seedling box 23 is disposed with a feeding gap so as to face below the transfer start end of the first transfer body 10, and the tape-shaped seedling 9 is lifted from the seedling box 23. The first transport member 10 is suspended in the air and reaches the transport start end position of the first transport body 10 through the feeding gap. As a result, seedling box 2
The tape-like seedling 9 fed out from 3 is a conventional tape-like seedling 9
Is displaced along the folding direction, so that there is no problem that the seedling posture is disturbed by being entangled with the tape-like seedling 9 of the subsequent stage or the seedlings are caught and the feeding of the tape-like seedling is hindered, The seedlings will be fed out orderly with the posture of the seedlings maintained, so that it is possible to effectively prevent the occurrence of poor planting such as empty planting or falling seedlings.

In addition, the first carrier 1
The leading end of the stalk portion of the tape-like seedling 9 that is about to be drawn into the transport start end of the first transporter 10 is positively moved by the feed claw 15a of the spacer roller 15 provided at the transport start end of the first transport body 10. The seedlings are drawn in, rectified, and transferred to the conveyor belts 10a and 10b. As a result,
Even if the tip of the stem remote from the tape portion 9a of the transplanted seedling hangs down at the stage of being suspended in a suspended state and hangs slightly, the hanged portion is the conveyance belt of the first conveyance body 10. At the stage where the feed start ends 10a and 10b are retracted with a change in direction, the feed claws 15a receive an aggressive rectifying feed action.
In this case, there is no problem that the seedling posture is greatly disturbed further later, so that the disturbance of the seedling posture can be minimized, the seedling transplantation can be reliably performed, and the tape material 9a supports the seedling. The width can be made as narrow as possible to facilitate cutting.

Further, in this embodiment, since the seedling mounting table 8 is disposed by effectively utilizing the space below the seedling feeding and transporting body 7, the front-rear length of the working machine can be reliably shortened, and the size can be reduced. And the height of the seedling mounting table 8 can be set low, so that the operation of placing the seedling box 23 filled with the tape-shaped seedlings 9 on the seedling mounting table 8 is facilitated. The work load on the worker can be significantly reduced as compared with the case where the stand is disposed on the extension line of the transfer start end of the seedling feeding transfer body. Also,
Since the tape-shaped seedlings 9 fed from the seedling box 23 are lifted up to the tape-shaped seedlings 9 of the succeeding stage accommodated in the seedling box 23 and are fed to the first carrier 10 side, There is also an advantage that the trouble that hindering the orderly and smooth feeding of the seedlings, which is caused by the tape-like seedlings 9 to be fed being entangled with the tape-shaped seedlings 9 in the succeeding stage, can be surely prevented.

[Effects] In summary, since the present invention is constructed as described above, the tape-shaped seedlings fed from the seedling storage unit are suspended in the air and drawn into the transport start end of the seedling delivery carrier. At this time, the seedling part separated from the tape material of the tape-shaped seedling is positively drawn into the transfer start end side in a state where it is subjected to a rectifying action by the seedling pull-in body provided at the transfer start end of the seedling feeding transfer body. become. As a result, even if the part of the transplanted seedling that is separated from the tape material hangs at the stage of hanging in the air,
At the stage where the hanging part is retracted in a state where the direction is changed at the transport start end of the seedling feeder, the positively rectifying and retracting action of the seedling retractor causes the seedling feeder to move to the transport start end of the seedling feeder. As a result, it can be effectively avoided that the attitude of the seedling of the tape-shaped seedling is disturbed, so that the orderly transplanting of the seedling can be reliably performed.
