Further, bolts (not shown) are inserted through the bolt insertion holes 41 and 42 that are matched. And by performing such an operation | work about each main body 2, the attachment height with respect to the rotary rear touch 53 of each seedling transplanter 1 and by extension, and a farm field can be adjusted separately.

  Note that a pair of spare seedling stands 54L and 54R are attached to the rotary rear touch 53 of the tractor 51 (agricultural machinery) in the left-right direction. Further, the rail 33 has an extension 33A formed by extending the left end side, and a marker 55 serving as a base for determining a travel line of the tractor 51 is attached to the extension 33A.

(Function)
Next, the operation of this embodiment will be described. Here, the six seedling transplanters 1 are connected in parallel, that is, in a side-by-side state to the rotary rear touch 53 provided at the rear portion of the rotary device 52 of the tractor 51 (agricultural machinery) by the connecting mechanism 31 described above. Is done. In addition, the transplant object is a rakcho seedling grown in each individual pot body of the continuous potted seedling 7 accommodated in the seedling box 8.

  First, the nursery box 8 containing the continuous potted seedlings 7 is set on the seedling stand 4 (potted seedling placement unit) of each seedling transplanter 1. A slope (not shown) is provided between the bottom of the seedling box 8 and the continuous potted seedling 7 (when an underlaying paper is laid under the continuous potted seedling 7, between the underlaying paper and the bottom of the seedling box 8). ) Is eliminated, the level difference between the seedling raising box 8 and the bottom plate 9 of the potted seedling guide part 5 is eliminated. In addition, the continuous potted seedling 7 is moistened to such an extent that the water-soluble glue used for bonding dissolves.

  Next, after stopping the tractor 51 at the transplant start position in the field and further lowering the rotor rear touch 53, the tractor 51 is advanced by a certain distance. Thereby, the field is cultivated by the rotary device 52 (plowing device), and the planting groove 20 is formed in the cultivated part of the seedling transplanter 1 in the cultivated part of the seedling transplanter 1, and the planting is also performed. At the bottom of the groove 20, a bottom groove (fixed planting groove) is formed by the groove cutting part 25.

  Next, a single continuous potted seedling 7 is pulled out from the seedling box 8 placed on the seedling stand 4 of each seedling transplanter 1, and the drawn continuous potted seedling 7 is used as a pair of guides in the potted seedling guide unit 5. The tip of the continuous potted seedling 7 of each seedling transplanter 1 is passed through the guide plates 13 between the plates 10L and 10R and the potted seedling feeding part 6, and the bottom groove of each corresponding planting groove 20 formed in the field. In other words, it is fixed to the bottom of each planting groove 20. In this state, when the tractor 51 is moved forward while the rotary device 52 is operated, as the tractor 51 moves forward, six planting grooves 20 are continuously formed in the field by the groove forming portion 21 of each seedling transplanter 1. At the same time, a bottom groove (fixed planting groove) is formed at the bottom of each planting groove 20 by the groove cutting part 25 of each main body 2.

  Then, in conjunction with the formation of the planting groove 20 by the groove forming part 21 of each seedling transplanting machine 1 and the formation of the bottom groove by the groove cutting part 25, a single continuous potted seedling 7 aligned by the potted seedling guide part 5 is formed. It is fed out from the potted seedling feeding part 6 of each seedling transplanting machine, in other words, fed out from the notch 24 of each seedling transplanting machine 1. A single continuous potted seedling 7 fed from the potted seedling feeding part 6 of each seedling transplanter 1 is sequentially planted in the bottom groove of each corresponding planting groove 20 formed in the field.

(effect)
According to this embodiment, the groove forming portion 21 for forming the planting groove 20 in the field, and the groove cutting portion 25 for forming the bottom groove (fixed planting groove) at the bottom of the planting groove 20 formed by the groove forming portion 21. Is provided in the main body 2 (transplanter main body) to constitute the seedling transplanter 1, so that the seedling transplanter 1 can simultaneously perform grooving and fixed planting.
Thereby, it is possible to omit the groove forming work by the conventional management machine etc., and a series of work concerning transplantation of the continuous potted seedling 7 can be made efficient. In addition, since the seedling transplanting machine 1 is provided with a connection mechanism 31 that connects the rotary device 52 (cultivation device) of the tractor 51 (agricultural machinery) to the rotary rear touch 53 (rear part), the management device or the like can be used before transplanting. Compared with the case of grooving, the transplanting operation of the continuous potted seedling 7 can be made more efficient and the burden on the operator can be reduced.
Conventionally, since the continuous potted seedling 7 is transplanted in the separately formed planting groove 20, the side wall of the planting groove 20 naturally collapses or collapses with the movement of the seedling transplanting machine, so that Although it became impossible to transplant seedlings or the continuous potted seedlings after the transplanting were covered with soil, there was a problem that hindered the growth of the seedlings. Since the seedling 7 can be transplanted at the same time, such a situation can be eliminated.
In addition, conventionally, when the side wall of the planting groove 20 collapses due to transplanting work, preparation work, strong wind, etc., from the grooving by the management machine to the completion of the planting by the seedling transplanting machine, the continuous potted seedling 7 is appropriate It becomes impossible to plant at a depth, and management work after planting such as soil gathering, weeding, cultivating soil, etc. may be difficult, but in this embodiment, molding of the planting groove 20 and transplanting of the continuous potted seedling 7 Since this can be performed simultaneously, such a situation can also be eliminated.
Moreover, since the groove formation part 21 shape | molds the planting groove 20 in a farm field, ie, shape | molds the side wall of the said planting groove 20 in V shape, forming the planting groove 20 in a farm field, for example, sand dunes etc. The side wall of the planting groove 20 can be prevented from collapsing in a soft field.
Furthermore, since the continuous potted seedlings 7 are planted in the planting grooves 20 (deep grooves) formed by the groove-growing portion 21, they are exposed to sunlight and air by the soil cultivated with soil that is piled up on both sides in the width direction of the planting grooves 20. It is possible to prevent the quality of the continuous potted seedling 7 (for example, “Rakkyo”) from being deteriorated.

In addition, since the connection mechanism 31 can connect a plurality of seedling transplanters 1 to the rotary rear touch 53 in parallel (side by side) at an arbitrary interval, the seedling transplanter 1 can be connected to the continuous potted seedlings 7 simultaneously. It can be applied to transplantation.
Moreover, in this embodiment, since the seedling stand 4 (potted seedling placement part) was inclined in the left-right direction with respect to the horizontal plane, the seedling stand 4 was installed horizontally, and eventually the seedling box 4 grew the seedling box 8. It is possible to reduce the space in the left-right direction occupied by the nursery box 8 as compared with the case where the seedling box 8 is supported horizontally, and thus the space in the left-right direction is set to the minimum mounting pitch P between the adjacent main bodies 2. The following can be suppressed. As a result, simultaneous multiple streak transplantation is possible with a narrower width than the width of the seedling box 8 (for example, 30 cm). For example, seedlings such as raccoon and onion can be transplanted simultaneously with a normal streak (for example, 24 cm). Can be transplanted.

In the present embodiment, since the plurality of seedling transplanters 1 are connected to the rotary rear touch 53 (rear part) of the rotary device 52 of the tractor 51 by the connecting mechanism 31, the operator can perform a plurality of operations from the driver seat of the tractor 51. The transplanted state of the continuous potted seedling 7 can be visually observed.
Moreover, the connection mechanism 31 is for adjusting the attachment angle adjustment mechanism for adjusting the inclination angle with respect to the field of the plurality of seedling transplanters 1 and for adjusting the mounting height of each seedling transplanter 1 with respect to the rotary rear touch 53 individually. Since the mounting height adjusting mechanism is included, it is possible to individually adjust the mounting height of the plurality of seedling transplanting machines 1 with respect to the field, and thus adjust the depth of the planting groove 20 to be molded in the field. be able to.
Furthermore, since the tractor 51 (agricultural machine) is equipped with a pair of spare seedling stands 54L and 54R, the seedling box 8 placed on the seedling stand 4 (potted seedling placement portion) of the seedling transplanter 1 during the transplanting operation. When the continuous potted seedling 7 becomes empty, it is possible to replace the empty seedling box 8 and the seedling box 8 stocked in the spare seedling stands 54L and 54R on the spot, and transplantation work Can be streamlined.

In addition, embodiment is not limited to embodiment mentioned above, For example, it can comprise as follows.
For example, when a leek seedling is transplanted using a conventional ambulatory transplanter, fertilization, drug spraying, and grooving are separately performed before using the transplanter, but the tractor 51 in this embodiment is used. By attaching a fertilizer application device or a chemical spraying device to the front side or the rear side of the rotary device 52 (cultivation device) of (agricultural machinery), it is possible to perform these pre-operations together with transplantation of the continuous potted seedling 7. The management work after transplanting the continuous potted seedling 7 can be streamlined.
Further, in this embodiment, the pair of spare seedling stands 54L and 54R are installed in the rear part of the tractor 51 (agricultural machinery). In addition, as shown in FIG. Can be equipped.
In addition, a soil covering member is provided at the rear end portion of the pair of shaping walls 22L and 22R of the groove forming portion 21, and the continuous potted seedling 7 planted in the bottom portion (bottom groove) of the planting groove 20 is covered with the soil. can do.
Moreover, in this embodiment, although the planting groove | channel 20 formed by the groove producing part 21 was made into V groove | channel, it is not intending to limit to this, For example, the trapezoid groove | channel suitable for transplant of a leek is formed. The groove forming portion 21 can be configured as described above. In this case, the groove forming portion 21 is configured so that the lower ends of the pair of shaping walls 22L and 22R are not connected by a ridge but the pair of shaping walls 22L and 22R are connected by a bottom wall (horizontal plane).
