[0001]

[Industrial applications]

 The present invention relates to a tape-shaped seedling transplanting machine that supports a series of transplanted seedlings such as strawberries, sardines, green onions, and garlic.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Generally, when transplanting this seedling transplanted seedling to a field, a tape-shaped seedling in which the transplanted seedling is held in a series is formed in advance, and the formed tape-shaped seedling is transplanted to the field using a transplanting work machine. Although proposed, in this case, the transplanting working machine needs to be provided with a carrying section for carrying the tape-shaped seedlings placed on the transplanting working machine toward the transplanting section. Therefore, it is proposed that the transport section is configured by a pair of transport belts that are arranged in parallel to transport the roots and stems of the tape-shaped seedlings, respectively. Since the stalks of the seedlings are disturbed and it is difficult to carry out the orderly transfer of the seedlings, there is a risk that the stalks whose posture is disturbed may be caught on a member near the transport section or wrapped around the rotating section, interrupting the work. It was not forgiving and there was a problem that the seedling posture in the transplanting part was disturbed and the accuracy of transplanting decreased.

[0003]

[Means for Solving the Problems]

 The present invention was devised with the object of providing a tape-shaped seedling transplanting machine capable of eliminating these drawbacks in view of the above-mentioned circumstances, and a tape for holding transplanted seedlings in a series. And a transfer section for transferring the tape-shaped seedlings stored in the storage section, and a transfer section for transferring the tape-shaped seedlings to the field at the transfer end position of the transfer section. A pair of conveyor belts for conveying the roots and stems of the tape-shaped seedlings respectively are installed side by side, and at the opposite positions of the conveyor belts on the stalk side, a stem retainer for controlling disturbance of the stalks is provided. It is characterized by having a body. With this configuration, the present invention solves the problem that the stem portion of the tape-shaped seedling disturbs the posture in the transport section, reliably prevents the stem portion from being caught or wrapped around, and significantly improves the transplanting accuracy. It is something that can be measured.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 is a transplanting work machine for strawberries connected to a traveling body, and a frame 2 of the transplanting work machine 1 is provided with a transmission case 3 in which a power transmission mechanism is installed, and a bottom of the transmission case 3. The rice field gliding float 4, the storage unit 6 in which the strawberries and seedlings 5 are stored in the lying posture, the first transporting unit 7 for feeding and transporting the strawberries and seedlings 5 stored in the storing unit 6 in the lying posture, the first transporting unit The second transfer section 8 that further conveys the strawberries 5 in the lying position received at the transfer end position of 7 and further conveys them while raising the strawberries 5 in the standing position received at the transfer end position of the second transfer section 8. The transplant nail 9 etc. which are transplanted to a field are attached.

The strawberries seedlings 5 accommodated in the accommodating portion 6 are formed in a so-called tape-shaped seedling 11 by being preliminarily held in a series near the root part with an adhesive tape 10 and formed into the tape-shaped seedling 11. The sow seedlings 5 thus formed are folded in a zigzag shape in the front-rear direction to be housed in the seedling box 12, and are also mounted on a mounting frame 13 fixed to the upper end of the frame 2.

On the other hand, the first carrying section 7 feeds the tape-shaped seedlings 11 housed in the seedling box 12 in a suspended manner, and the tape-shaped seedlings 11 that have been fed out are in a lying position, and the tape-shaped seedlings 11 are conveyed downward in the second carrying direction. The stalk conveyor belt 14 and the root conveyor belt 15 are provided side by side in parallel in order to convey the conveyor obliquely toward the feeding section 8. A pair of upper and lower pulleys 14a, 14b around which the conveyor belts 14, 15 are respectively suspended. 15a and 15b are integrally fixed respectively to a pair of upper and lower rotating shafts 16 and 17 which are axially supported in the left-right direction, and lower pulleys 14b and 15b associated with driving of the lower rotating shaft 17 are provided. Both conveyor belts 14 and 15 are operated in the same direction and at the same speed based on the rotation of. Reference numeral 18 denotes a feed roller that positively draws (rectifies) the tape-shaped seedling 11 between the pulleys 14a and 15a.

Further, reference numeral 19 denotes a root pressing belt disposed at a position facing the root conveying belt 15 above, and the root pressing belt 19 forms a root portion of the tape-shaped seedling 11 between the root pressing belt 19 and the root conveying belt 15. Although it is suspended by a pair of upper and lower pulleys 19a and 19b so as to be sandwiched, a rotating shaft 20 supporting the lower pulley 19b is arranged in parallel above the rotating shaft 17 while supporting an upper pulley 19a. The rotating shaft 20a is integrally projectingly provided on the upper end of a swing plate 21 whose base end is supported by the rotating shaft 20 so as to be vertically swingable. That is, the stem pressing belt 19 is configured so that it can be transformed into a transporting position in which the root transporting belt 15 is closely opposed to the root transporting belt 15 and a non-transporting posture in which it is separated from the root transporting belt 15 based on the vertical swing operation of the swing plate 21. Therefore, when the tape-shaped seedlings 11 are set in the transport path or maintenance of the transport path is performed at the beginning of work, the workability is remarkably improved by retracting the root holding belt 19 to the non-transport position. It is getting better. Incidentally, 22 is a handle integrally provided on the upper end of the rocking plate 21, and 23 is an arbitrary hand of the rocking plate 21 by locking an L-shaped member 24 protruding from the middle part of the rocking plate 21. It is a locking piece that regulates the retracting swing.

Reference numeral 25 denotes a bracket fixed to the projecting piece 21a of the rocking plate 21 by a bolt 26 so as to project toward the stalk conveying belt 14 side, and a seedling is provided at an intermediate portion of the bracket 25. By pressing the tape-shaped seedling 11 against the seedling breakage sensor 27 arranged at the lower position of the transport route, a seedling holding rod 28 is attached to prevent erroneous detection due to floating of the seedlings. Further, an upper end of a stem pressing frame 29, whose lower end is vertically swingably connected to the rotating shaft 20, is integrally formed at the front end of the bracket 25 reaching the upper direction of the stalk conveying belt 14. Fixed. Immediately, the stem pressing frame 29 is configured to swing integrally with the swing plate 21 and the root pressing belt 19, but when the root pressing belt 19 is in the transporting posture, the stem pressing frame 29 is The stalk portion of the tape-shaped seedling 11 is sandwiched between the stalk portion conveying belt 14 and the stalk portion conveying belt 14 at a predetermined interval so as to sandwich the stalk portion. Disturbances are being regulated without fail. However, the facing distance is set to be larger than the facing distance between the root conveying belt 15 and the root pressing belt 19, so that it is possible to avoid pressing the stem portion against the stem conveying belt 14 forcibly. It surely prevents damage to the stem and increase in sliding resistance.

Furthermore, 30 is a reinforcing plate formed in the shape of a substantially right triangle, and the short side portion of the reinforcing plate 30 is attached to the projecting piece 21 a of the rocking plate 21 by the bolt 26. While being tightened, the long side portion extending to the pulley 19a side comes into contact with the inner side surface of the oscillating plate 21 to regulate the deformation of the oscillating plate 21. That is, since the pulley 19a is supported in a cantilever manner at the front end of the swing plate 21, there is a risk of deformation when excessive tension is applied to the root pressing belt 19, and this deformation is reinforced. Based on the abutment of the plate 30, the block is surely blocked.

By the way, the second transport unit 8 is configured by a pair of transport belts 31 and 32 that are twisted by approximately 90 ° in the transport process. In the second transport section 8, the intermediate portion of the tape-shaped seedling 11 is sandwiched at the transport end position of the first transport section 7, and the sandwiched tape-shaped seedling 11 is gradually raised toward the transplanting nail 9. It is supposed to be transported.

In the embodiment of the present invention configured as described above, the pair of left and right conveyor belts 14 and 15 arranged side by side in the first conveyor 7 suspends the tape-shaped seedlings 11 housed in the seedling box 12. While the tape-shaped seedlings 11 are fed upward, the tape-shaped seedlings 11 that are fed are inclined and conveyed toward the second lower conveyance section 8 at the rear lower side in the lying posture. The stalk conveying belt 14 is conveyed while being sandwiched between the stalk pressing frame 29 and the stalk pressing frame 29 that is closely opposed to the stalk conveying belt 14, and the disturbance of the posture is surely regulated. Therefore, it is not possible to allow orderly transfer of seedlings without disturbing the stalks, and reliably eliminate the problem that the stalks that have a disturbed posture get caught in a member near the transfer part or are wound around the rotating part. As a result, it is possible to improve the transplanting accuracy by improving the seedling posture in the second transporting section 8 and the transplanting nail 8 site, and to reliably avoid the interruption of the work due to winding or the like. Work efficiency can also be significantly improved.

Moreover, since the facing distance between the stalk conveying belt 14 and the stem pressing frame 29 is set to be larger than the facing distance between the root conveying belt 15 and the root pressing belt 19, the stalk portion is forced to move. Since it is not pressed against the conveyor belt 14, damage to the stem and increase in sliding resistance can be reliably prevented.

Furthermore, in the embodiment, since the stem pressing frame 29 is attached by using the bracket 25 for attaching the seedling pressing rod 28, it is not possible to reduce the number of parts by sharing the parts. The structure can also be simplified.

Further, in the embodiment, since the deformation of the swing plate 21 is regulated by the reinforcing plate 30, there is a problem that the root pressing belt 19 is detached from the pulleys 19a and 19b due to the deformation. It can be surely prevented.

Furthermore, since the reinforcing plate 30 is not allowed to be attached using the fixing bolt 26 of the bracket 25, it is simply contacted with the tip of the swing plate 21. In addition to reducing the number of parts and assembling man-hours, the structure can be remarkably simplified.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and as in the second embodiment shown in, for example, FIG. You may make it extend to the conveyance start end position. In this case, if the upper end portion of the stem pressing frame 29 is connected to and supported by the rotary shaft 20a via the tubular member 31, the reinforcing plate 30 is not provided, unlike the first embodiment. The stem pressing frame 29 can restrict the deformation of the swing plate 21.

[0017]

[Operation effect]

 In short, since the present invention is configured as described above, the root portion and the stem portion of the tape-shaped seedlings are respectively conveyed to the conveyance portion that conveys the tape-shaped seedlings from the storage portion to the transplantation portion. Although the pair of conveyor belts are arranged side by side, the stems of the tape-shaped seedlings conveyed by the stem-side conveyor belts are stalk pressers arranged at the positions opposite to the stem-side conveyor belts. Therefore, the disturbance of the posture is surely regulated. Therefore, it is possible to transport the tape-shaped seedlings in an orderly manner, but it is also possible to eliminate the problem that the stem part gets caught on a member near the transfer part or wraps around the rotating part. It is possible to improve the transplanting accuracy by improving the seedling posture in the plant, and it is possible to surely avoid the interruption of the work due to wrapping, etc., and to significantly improve the work efficiency.
