[Industrial applications]

 The present invention relates to a long seedling taping machine for connecting long seedlings such as long onions, onions, lacquers, strawberries, or corns with tape so as to plant them in a field at a predetermined interval.

[0002]

[Prior art]

 Conventionally, the seedlings were raised in a mat shape like rice, and the long seedlings, which were difficult to plant by splitting the mat seedlings one by one with the planting claws of the planting device, were laid down sideways. There is already known a taping machine in which an intermediate portion or a root portion of a stem or a leaf is connected with a tape and the tape is wound sideways or wound in a zigzag shape.

[0003]

[Problems to be solved by the device]

 In the known taping machine, after the seedlings are connected with tape, the seedlings are crossed with each other when wound or folded, so that the leaves or leaves are not stored during storage, carrying, or loading into the planting device. The stem was bent and the seedlings were sorely pained that growth failure occurred after transplantation. Also, when transplanting with a transplanter, if the seedlings are crossed, the divided seedlings fall in an oblique posture, clogging the guide part and causing a planting error, and the seedlings fall sideways and fall into the field. It sometimes withers and runs out of stock.

[0004]

[Means for Solving the Problems]

 The present invention conveys long seedlings in a lying posture, and provides a connecting device for connecting long seedlings at a predetermined interval with a tape along a moving path on the tip side while conveying the long seedlings, and the connecting side of the connecting device is vertically connected. The above-mentioned problem is solved by arranging detachably a winding reel that rotates around the axis and converts the tape so that its surface is in the vertical direction and winds the seedlings in a suspended posture. did.

[0005]

[Action]

 While driving the transport device, long seedlings are fed to the transport device at an interval of one or one plant at a time in a horizontal position and transported, and the tape is pulled out at the site corresponding to the leaf tip side on the transport end side. The seedlings in front and back are connected by adhering to the tips of the leaves, and the fed tape is taken up by a take-up reel that rotates around the vertical axis. What was along was the vertical direction at the time of winding, and the long seedlings were wound in a suspending posture so that they would not intersect or get entangled with each other. After winding a predetermined amount, the take-up reel is replaced.

Explaining the transplanting operation, the take-up reel 28 wound with taping seedlings in the above-mentioned winding step is rotatably held by the receiving pin 90 and the locking pin 93, and the adhesive tape 7 is pulled out. When the transplanter is driven with the gear 85 and the idler gear 86 engaged with each other after passing between the guide roller 99a which rotates at a fixed position and the guide roller 99b which can be adjusted in position, the machine advances. The planting arm 61 moves up and down, and the regulating link 69 also rises and pulls the wire 88 in the ascending process, so that the ratchet arm 87 rotates, which causes the ratchet wheel 84a and the toothed wheel 85 to rotate. Therefore, the floating gear 86 meshing with the gear 85 is also rotated to pull out the adhesive tape 7 at a high speed while biting the adhesive tape 7, whereby the adhesive tape 7 is guided. The knife 100 is tensioned between the drag rollers 99a and 99b and the gears 85 and 86, and the knife 100 cuts the tip of the seedling leaf in a drooping position with its root part down, immediately below the adhesive tape 7. The seedlings fall into the shooter 101 in a substantially vertical posture, and move to the raised receiving hopper 65 in a substantially unchanged posture.

At this time, the movable claw 66b of the planting claw 66 is being closed by the fan-shaped cam 75 via the rod 73, and when the planting claw 66 rises in this state, it is fixed to the receiving hopper 65 and raised. When the opening / closing guide 106 lowers from the upper limit of the rise, the attachment 105 is pushed to open the stopper 105 against the ammunition 108, so that the seedling moves through the receiving hopper 65 into the planting claw 66 and is retained. The crank pin 70 subsequently rotates and the planting claw 66 descends. At the lower limit of the descending, the planting claw 66 penetrates into the field to form a hole, and the movable claw 66b is opened by the fan-shaped cam 75 to operate, so that the seedling is cultivated in the field. The planting claw 66 is planted in an upright posture, the movable claw 66b is closed during the upward movement of the planting claw 66, the gear 85 and the idle gear 86 are rotated, and the seedling cutting described above is performed. The adhesive tape 7 with the leaf tips pulled out by these gears 85 and 86 is collected in the basket 103 attached to the front part of the handle 102 whose rear part is opened left and right. When the ridges in the planted field are covered with a multi-sheet, the front wheels 55 and the rear wheels 58 are adjusted up and down according to the height of the ridges, and they are moved in the groove between the ridges. Break through the multi-sheet and penetrate the soil to a specified depth to plant seedlings.

In such a planting process, since the machine body pitches and rolls due to unevenness of the field during traveling, the take-up reel 28 vibrates up and down and left and right and back and forth while a lot of seedlings are suspended. Although it sways, the skewer bars 44, 44 do not slide down because they receive the lower surface of the layer around which the adhesive tape 7 is wound, and are rewound while being held at a constant height.
