[Problems to be Solved by Prior Art and Invention]

 Generally, as a method of transplanting this seedling transplanted seedling to a field, there is a method of transplanting the seedling seedling to a field using a tape-shaped seedling formed by continuously binding the seedlings with a tape material. When the tape-shaped seedlings are transplanted in this way, the tape-shaped seedlings that are as long as possible are compactly housed and placed in the transplanter, and the tape-shaped seedlings are sequentially fed out and transplanted. By the way, for stable placement of such long tape-shaped seedlings, it is preferable to store and place the seedlings in a lying posture, and therefore, the tape-shaped seedlings that are stored in a lying shape in the seedling storage section are lifted. However, it will be forcibly transported and supplied to the seedling transplantation device via the seedling carrier. On the other hand, the tape-shaped seedlings are not always formed by continuously binding the center of gravity of the transplanted seedlings with a tape material, and thus the tape-shaped seedlings are continuously formed in a state shifted from the center of gravity of the seedlings. When the tape-shaped seedlings are lifted from the seedling storage section as described above, the heavy-sided seedling part will inevitably have a slanting posture, and in this posture it will be drawn into the seedling carrier, and the seedlings with planting will be drawn. It is one of the major factors that disturbs the transplanting posture.

Are conventional.

The seedling carrier 7 includes a first carrier 10 for feeding and feeding a tape-shaped seedling 9 from a seedling storage portion 8 described later while keeping a sideways posture, and the fed planting seedling 9 gradually. The second transport body 11 transports in the direction of the transplanted nail 6 while standing upright, and is inclined in a front high rear low shape. Here, the tape-shaped seedling 9 is obtained by attaching the root portion of the seedling or the stem portion in the vicinity thereof with a tape material 9a such as an adhesive tape (when necessary, the tape material 9a is sewn or wound with a string or the like. Tape peeling may be prevented) In this embodiment, the seedlings are supported so that they are clamped from both sides, and the seedlings are supported continuously, but of course, intermittently. You may support it.

The first conveyor 10 includes a conveyor belt 10a on the root side and a conveyor belt 10b on the stalk tip side, which are opposed to each other in the left-right direction at a predetermined interval. These conveyor belts 10a, 10b. Has a concavo-convex rib shape on the conveyance surface, and a conveyance start end (a slanted upper end portion) of a plurality of partition plates 12 for partitioning that are integrally provided on the conveyance body frame 7a at predetermined intervals in the left-right direction. ) Side and the end (inclined intermediate portion) side are suspended by pulleys 13a, 13b, 14a, 14b integrally supported by support shafts 13, 14 supported horizontally. Further, a pair of spacer rollers 15 and 16 are integrally incorporated between the left and right conveyance start end side pulleys 13a and 13b. Among these, a plurality of feed blades 15a are projected on the spacer roller 15 on the stem tip side. The feeding blades 15a and the spacer rollers 15 are made of an elastic material, but the seedlings are positively drawn in (rectified). Of course, both spacer rollers 15 and 16 may be provided with feed vanes if necessary. Further, the spacer rollers 15 and 16 can be integrated with each other, and the spacer rollers 15 and 16 can be integrated with the pulleys 13a and 13b, respectively, and further, the pulleys 13a and 13b and the rollers can be integrated. It is also possible to integrate all 15, 16 together. Reference numeral 17 is a seedling pressing body, and the seedling pressing body 17 is attached to the partition plate 12 via a pressing ammunition machine 17a so as to elastically swing. The pressing position is the moving position of the tape material 9a. In addition, the seedling-holding body 17 has a seedling-holding action so that the tape-shaped seedlings 9 supplied from the seedling storage section 8 are transferred by the first carrier 10 as described later. The conveyance start side is long so that it operates from the start side.

On the other hand, the second transport body 11 is arranged so as to be positioned between the transport end portions of the transport belts 10 a and 10 b facing each other, and the transport start end side thereof is the support shaft 14 and the support shaft 14. Pulleys 14c respectively provided on horizontal support shafts 18 that are pivotally supported by the partition plate 12 in the upper position (the pulley 14c may be integrated with either one or both of the pulleys 14a and 14b, if necessary). 18a, and the end of conveyance is suspended by pulleys 20a and 21a provided on support shafts 20 and 21 supported upright on a guide plate 19 and twisted by 90 degrees during the course of conveyance. The transport belts 11a and 11b are formed by a pair of transport belts 11a and 11b, and the transport belts 11a and 11b are tape-shaped transported at the transport end portion of the first transport body 10. The seedling 9 is sandwiched between the roughly central portions by the transfer surface in which the concavo-convex ribs that face each other are meshed like a gap, and then gradually raised and transferred toward the transplant claw 6 arranged at the end of the transfer. Therefore, the transplanted nails 6 are used to scrape the unit planting seedlings and plant them in the field. Further, in carrying out the present invention, the seedling carrier 7 need not be divided into the first carrier 10 and the second carrier 11, but may be in a series form. is there. Further, the tape-shaped seedlings 9 may be erected at the transport start end without being erected on the way, or further erected by the transplanting nails 6.

The seedling storage portion 8 is for mounting a box-shaped seedling box 23 having an open top surface, and the tape-shaped seedlings 9 are folded in a zigzag shape in the front-rear direction in the stacked state. (If the tape-shaped seedlings 9 can be stored in a zigzag shape, it is not limited to the box having only the upper surface opened as in the embodiment. In place of 3, a seedling container having an appropriate shape such as a plate without an inclined upper side surface (front face) can be adopted if necessary), but the seedling housing part 8 has a gap below the first carrier 10. Are installed. In other words, the seedling accommodation section 8 is provided integrally with the seedling placing frame 24 having a substantially square shape provided integrally with the carrier frame 7a and the working machine stay 2a integrally planted with the transplanting working machine 2. From the upper part of the partition plate 12, a seedling box support 25, which is a substantially L-shaped plate-like body whose base end is integrally supported by the bracket 2b and whose tip (front end) is supported by the seedling placing frame 24, is formed. The seedling box support 25 is provided with a partition plate 12a extending downward and partitioning the placement position of the seedling box 23 corresponding to each transplant. A feeding gap for the tape-shaped seedlings 9 is provided below the seedlings, that is, in the embodiment, the seedling box 23 placed in a tilted posture of front high and low is separated downward from the transport start end position of the first transporter 10. , And the intermediate position in the front-rear direction of the seedling box 23 from the transport start position ( In the embodiment, the feeding gap is formed by setting the feeding gap closer to the central position so that the gap can be narrowed, which is preferable, and the seedling box 23 of the tape-shaped seedling 9 is formed. The feeding path from the first conveyance body 10 to the conveyance start end position is not the one that is fed and moved forward and backward with respect to the tape-like seedling 9 on the succeeding stage that is fed next after the folded storage state. It is set so as to be lifted upward and fed out in a separated state.

In driving the first and second conveyors 10 and 11, the power from the drive pulley 29 is transmitted to the support shafts 14 and 18 via the chain transmission mechanism 30, and the support shafts 14 and 18 are driven. It is configured to be done by the drive of.

In the embodiment of the present invention configured as described above, as described above, the tape-shaped seedlings 9 which are folded and housed in the seedling box 23 in a zigzag shape are arranged in the first transporting body at a timing when the machine is running. 10, and the transplanted seedlings addressed to the unit planting seedlings are transferred to the field by the transplanting nails 6 via the second carrier 11, and the tape-shaped seedlings 9 fed out from the seedling box 23. Moves to the conveyance start end side of the first conveyance body 10 while being separated from the tape-shaped seedling 9 in the subsequent stage so as to be lifted.

In other words, the seedling box 23 is arranged with a feeding gap so as to face the lower side of the transport start end of the first transporter 10, and the tape-shaped seedling 9 is lifted from the seedling box 23. Then, it is suspended in the air, passes through the feeding gap, and reaches the conveyance start end position of the first conveyance body 10. As a result, the tape-shaped seedlings 9 fed out from the seedling box 23 are entangled with the tape-shaped seedlings 9 in the succeeding stage and the seedling posture is disturbed, or the seedlings are caught by the seedlings and the feeding of the tape-shaped seedlings is hindered. Instead, the seedlings will be delivered in an orderly manner with the posture of the seedlings maintained, and it is possible to effectively prevent the occurrence of defective planting such as empty planting and lodging seedlings.

Moreover, the tip end side of the stem portion of the tape-shaped seedling 9 which is to be hung up and supplied to the transporting start end of the first transporting body 10 is provided at the transporting start end of the first transporting body 10 away from the tape material 9a. The feeding blades 15a of the spacer rollers 15 positively pull in the seedlings, rectify the seedlings, and transfer the seedlings to the conveyor belts 10a and 10b. As a result, even if the stem tip side of the transplanted seedling distant from the tape portion 9a hangs down at a stage of being suspended in the air, the hung down part of At the stage where the conveyor belts 10a and 10b are retracted at the transport start ends while the direction is changed, the feed blades 15a are positively rectified and retracted. Therefore, it is possible to prevent disturbance of the seedling posture to a minimum and to perform orderly seedling transplantation reliably, and to make the support width of the tape material 9a as narrow as possible. It can also be cut easily.

Moreover, since the feed blade 15a of the spacer roller 15 is formed of an elastic material, when the hanging portion of the tape-shaped seedling 9 is pulled in by the feed blade 15a, for example, the feed blade or the roller is used. It is possible to reliably avoid the problem that the transplanted seedlings are damaged, such as the one whose surface is made of metal.

Further, in this embodiment, since the seedling accommodation section 8 is arranged by effectively utilizing the space below the seedling carrier 7, the front-rear length of the working machine can be surely shortened and the size can be made compact. Since the height of the seedling storage section 8 can be set low, the seedling box 23 packed with the tape-shaped seedlings 9 can be easily placed on the seedling storage section 8. The work load on the operator can be clearly reduced compared to the case where the platform is arranged on the extension line of the transport start end of the seedling transporter. Further, since the tape-shaped seedlings 9 fed from the seedling box 23 are fed to the first carrier 10 side so as to be hung up with respect to the tape-shaped seedlings 9 in the subsequent stage housed in the seedling box 23, There is also an advantage that it is possible to surely prevent the trouble that the tape-like seedlings 9 that are fed out first are entangled with the tape-like seedlings 9 in the subsequent stage, which hinders the orderly and smooth feeding of seedlings.

The present invention is not limited to the above embodiment, and the feed blade 15a of the spacer roller 15 is, as shown in FIG. It may be provided in a state of being inclined toward, and in such a case, the seedling posture can be corrected more effectively by the feed blade 15a. As a seedling box for housing the tape-shaped seedlings 9, as shown in FIG. 6, a seedling box 26 is an upper box 26a having openings on both upper and lower sides, and a lower box which is fitted in the upper box 26a so as to be vertically movable. 26b, and the bottom of the lower box 26b is supported by the upper box 26a via the ammunition machine 26c so that the tape-shaped seedling material contained in the seedling box 26 is self-weighted. Alternatively, the lower box 26b may be configured to move up and down. In such a configuration, the lower box 26b moves upward as the tape-shaped seedlings 9 in the seedling box 26 are fed to the seedling carrier 7 side and become lighter. As a result, as described above, As described above, the tape-shaped seedlings 9 are hoisted and supplied to the seedling carrier 7, but the length of hoisting is short even if the seedlings are stored under the seedling box 26. Therefore, it is possible to surely avoid the occurrence of the trouble that the tape material 9a is cut because the lifting length becomes too long and heavy.

[Effects and Effects] In short, since the present invention is configured as described above, when the tape-shaped seedlings are lifted from the seedling accommodation portion and supplied to the transporting start end of the seedling transporter, the tape material is used. The seedling portion that hangs from the support portion is positively drawn to the transport starting end side while being rectified by the seedling retractor provided at the transport starting end of the seedling transporting body. As a result, the tape-shaped seedlings are supplied to the starting point of the seedling transporter in a state in which the seedling posture is corrected by the positive rectifying and drawing action of the seedling retractor, and the tape-shaped seedlings are fed. It is possible to effectively avoid disturbing the seedling posture and ensure orderly transplantation of seedlings. Moreover, in the seedling retracting body, at least the portion where the transplanted seedling comes into contact is formed of an elastic material, so that when the hanging portion of the tape-shaped seedling is pulled in by the seedling retracting body. , It is possible to surely avoid the problem that the transplanted seedling is damaged by the retractor.
