  FIG. 11 shows a partially enlarged perspective view of a seedling feeder transfer apparatus A which is an embodiment of the present invention. FIG. 11A shows a perspective view when the brush 57 is provided in front of the hole punching device D, and FIG. 11B shows a perspective view of the rubber plate 58 for leveling the surface of the seedling breeder 1. .

In FIG. 11, a brush 57 or a rubber plate 58 is provided in front of the hole punching device D for leveling the unevenness of the soil on the surface of the seedling device 1 without using the cell 1a. 1 is transferred in the direction of arrow G, and after smoothing the soil on the surface of the nursery device 1 with a brush 57 and a rubber plate 58, a hole is made in a place to cut and a cutting is made.
By adopting this configuration, the soil unevenness on the surface of the seedling raising device 1 can be eliminated, and the accuracy of cuttings such as the accuracy of the seedling insertion position and the depth of seedling insertion is improved.

  FIG. 11 (a) shows a case in which cuttings are made by making holes after making the surface irregularities of the soil contained in the nursery box 1 for sand insertion (the sand insertion box) flat by the brush 57. In the case of using the nursery device 1 as well, after making the unevenness of the soil surface flat, a hole is made and cuttings are made.

  Further, even if a rubber plate 58 as shown in FIG. 11B is provided in front of the drilling device D instead of the brush 57, the unevenness of the soil surface can be made flat. It is not limited to.

  On the other hand, cutting may be difficult depending on the type of seedling. For example, in the case of a soft seedling, the cutting portion is thin, and when the cutting is carried out by holding the seedling holding hands 5b and 5c, the chrysanthemum head 63 coming down from the seedling holding hands 5b and 5c has a long sprouting head, I cannot cut.

  FIG. 12 shows an exploded perspective view of the seedling support 15 according to one embodiment of the present invention, and FIG. 13 shows a partial perspective view thereof. 12 is a view corresponding to FIG. 4, and FIG. 13 is a view corresponding to FIG. 3. Therefore, the same members as those in FIG. FIG. 14 shows a state where the thin and soft chrysanthemum 63 is gripped from the seedling support 15, and FIG. 14 (a) shows a side view when FIG. 12 is viewed from the direction of the arrow L. (B) shows the AA arrow directional view of Fig.14 (a).

  FIG. 12 shows a state where the bottom raising material 60 is affixed or put inside the seedling extraction opening 15c of the seedling support 15 into which the chrysanthemum 63 is introduced, and the bottom raising material 60 is affixed or put. After that, the rubber 62 is placed on the rubber 62 mounting plate piece 15 i provided at the lower end on the near side of the seedling extraction opening 15 c and is fixed by the fixing tool 61. FIG. 13 shows a state where the bottom raising material 60 is set on the seedling support 15. Note that the rubber 62 may be attached to be inclined instead of vertically.

Then, as shown in FIG. 14, the gripping height of the seedling holding hands 5b, 5c is not changed, that is, the same as the case where there is no bottom raising material 60, and the lower end of the gripping chrysanthemum 63 is the bottom of the seedling holding hands 5b, 5c. The amount that comes out from the lower part (pointing to the Z dimension in FIG. 14) is reduced, and cutting is performed.
As the bottom raising material 60, a sponge, a resin mold, or the like can be used, and any material may be used, and the material is not limited to these.

If such a configuration is adopted, the height to be grasped by the seedling grasping hands 5b, 5c may be the same as that when the bottom raising material 60 is not provided, and the chrysanthemum ear 63 coming down from the seedling grasping hands 5b, 5c by the bottom raising material 60 is provided. By cutting the cutting length, that is, by cutting the Z dimension (FIG. 14 (b)), cutting of the thin and soft chrysanthemum ear 63 becomes possible.
By adopting this configuration, it is possible to cut thin and soft chrysanthemum ears 63, and the range of adaptation of seedling types is expanded.

FIG. 15 shows a partially enlarged perspective view of the seedling holding hands 5b and 5c. FIG. 15A shows seedling holding hands 5b and 5c according to an embodiment of the present invention, and FIG. 15B shows conventional seedling holding hands 5b and 5c.
The cutting conditions vary depending on the type of seedlings to be cut, but the cuttings hold the seedlings and insert them into the soil of the nursery 1 so that the method of holding the seedlings is important to improve the accuracy of cuttings. It is.

  As shown in FIG. 15, it is set as the structure (arm 5p, 5q) which extends the seedling holding hand 5b up and down to the seedling holding hand 5c among the seedling holding hands 5b, 5c holding the chrysanthemum 63. The arm 5p and the arm 5q can securely hold the fallen ear in the seedling support 15 vertically and can also hold the lower side of the chrysanthemum ear 63, so that the accuracy of cuttings is improved and the softer and thinner ear Can be cut, and the application range can be expanded.

  Since the seedling holding hands 5b and 5c for holding the chrysanthemum 63 are configured to extend up and down on the seedling holding hand 5b side (arms 5p and 5q), the entire seedling holding hand portion is lightened. Thus, the shake of the seedling holding hands 5b and 5c is reduced, and the accuracy of cutting is improved.

In the conventional seedling holding hand, the upper side of the seedling holding hand 5b is not extended. However, in this embodiment, the upper side of the seedling holding hand 5b is also extended (arm 5p in FIG. 15A), so that the seedling support is supported. The position of the chrysanthemum spike 63 that has fallen in the body 15 can also be corrected, and the accuracy of cuttings is improved.
Further, depending on the variety, although the lower side of the chrysanthemum 63 is several millimeters, it can be grasped, so that the thin and soft chrysanthemum 63 can also be cut.

  FIG. 16 shows a state where the stem core 64 of chrysanthemum pan 63 supported by the seedling support 15 is gripped by the seedling gripping hands 5b and 5c, and an arrow view corresponding to FIG. 14B is shown. FIG. 16 (a) shows a state of gripping with the seedling gripping hands 5b and 5c according to one embodiment of the present invention, and FIG. 16 (b) shows a state of gripping with the conventional seedling gripping hands 5b and 5c. Show.

  In the case of the conventional seedling grasping hands 5b and 5c shown in FIG. 16 (b), when the stem core 64 of the chrysanthemum ear 63 is tilted in the direction of the two-dot chain line, the stem 5R is regulated to regulate the stem position. Although the center 64 hits and can be corrected in the H direction, when the stem core 64 is tilted in the direction of the solid line in the figure, the stem core 64 is idle because there is no regulating body 5r, and the I direction It cannot be corrected. On the other hand, in the embodiment of the present invention shown in FIG. 16 (a), the upper side of the seedling grasping hand 5b is also extended (arm 5p in FIG. 15 (a)). The stem core 64 can be corrected in the J direction, and the lower side of the seedling holding hand 5b is also extended (arm 5q in FIG. 15 (a)), so that the stem core 64 hits 5q and in the K direction. Can also be modified. Thus, the position of the chrysanthemum spike 63 that has fallen in the seedling support 15 can be corrected, and the accuracy of cuttings is improved.

  FIG. 17 shows a partially enlarged perspective view of a seedling transfer device A which is an embodiment of the present invention. In the seedling transfer device A of the seedling raising device 1 of the chrysanthemum seedling cutting device, a brush 59 is provided on the guides 65 and 66 for regulating the width of the seedling raising device 1 and is placed on the edge of the upper surface of the under tray 67 of the seedling raising device 1 By automatically removing the cultivated soil, the nursery device 1 can be stopped accurately at the drilling position and the seedling insertion position.

  When a brush 59 is provided on the upper surface of the tray width restriction guide 65 of the seedling device 1 in front of the punching device D (FIG. 2) and the seedling device 1 is stuffed with soil, it is placed on the upper surface of the under tray 67 of the seedling device 1. It is configured to automatically remove the cultivated soil.

  If soil is put on the edge of the upper surface of the under tray 67 of the seedling breeder 1 when soil is filled in the seedling breeder 1, it is provided at a position where the cell can be detected by the punching limit switch 68 and the seedling insertion device side. The sensitivity of the seedling insertion position limit switch (not shown) may deteriorate and cause false detection. Therefore, when the soil is stuffed, the soil on the upper surface of the under tray 67 of the seedling device 1 is removed with the brush 59, thereby preventing erroneous detection of the drilling limit switch 68 and the seedling insertion position limit switch. . In this embodiment, the soil is removed by the brush 59. However, the material is not limited to the brush 59 and may be, for example, a rubber plate, as long as the soil can be removed.

  Since the transfer control of various seedling devices can be performed on the side of the transfer device that transfers the seedling device, the present invention can be used not only for seedling insertion devices but also for various transfer devices used in all technical fields.
