Description

  TECHNICAL FIELD The present invention relates to a root suction device for transplanting seedlings that simplifies planting of seedlings at the time of harvesting or vegetation of plants using a hydroponic cultivation device.

  In recent years, there is no need to use soil, high-density production is possible in a small indoor space, temperature and humidity can be adjusted without being affected by the weather, and contamination by various bacteria and pests can be removed. Hydroponic cultivation devices are attracting attention because of their many advantages such as ease of use. The hydroponic cultivation apparatus is generally a hydroponic cultivation apparatus in which a cultivating shelf for growing plants is arranged in multiple stages in the vertical direction at a predetermined distance and an illuminating device is provided on the upper side of each hydroponic container. Has been adopted.

  In the hydroponic culture using the hydroponic cultivation apparatus, in order to improve efficiency, the seeding step, the seedling raising step, the planting step, etc. are carried out by repeating transplantation (replanting) depending on the growth of the plant, When the seedlings are replanted from the seedling raising process to the planting process, they are carefully removed from the seedling raising vegetation parts so as not to damage the roots, and then vegetated on the planting parts for planting. Note that there is a seedling embedding mechanism that simplifies the transplanting of the seedlings (see especially Patent Document 1).

JP 2000-166408 A

  However, in the conventional seedling replanting method, there is a problem that the root part sticks to the periphery of the vegetation hole when vegetating for vegetation parts for planting, so it is complicated and time consuming to avoid or correct it. It was necessary to perform work that required. In addition, when a seedling embedding mechanism that simplifies planting of seedlings is used, turbulence is generated due to the small space below the vegetation holes, and the root is violently pulled to collide with the wall surface and cut. I was afraid that Further, in this mechanism, since the root part is sucked in the same direction as the hole axis of the vegetation hole, it is necessary to complicate the entire device so that water or nutrient solution does not reach the suction device.

  Therefore, focusing on the route for sucking the root portion, it is not configured in consideration of the size of the root portion, the operation range of the root portion at the time of suction, and the suction direction, and simplification of replanting can be performed without damaging the seedlings. It was clear that this was not done, and there was still room for improvement.

  Therefore, the present invention was created in view of the above problems, and provides a root suction device for transplanting seedlings, which simplifies the transplanting of seedlings in hydroponic cultivation and can improve the workability of cultivation suitably. With the goal.

In order to solve the above problems, the present invention is
A suction machine,
A vegetation plate having a plurality of vegetation holes, and a suction structure formed by stacking vegetation trays for receiving the vegetation plates,
A suction tube for communicating the suction device with the suction structure;
To have,
A root suction device for transplanting seedlings is provided.

  In the root suction device for transplanting seedlings of the present invention having such a configuration, even if the root part is slightly deviated from the vegetation hole, the vegetation plate is appropriately inserted into the vegetation hole while preventing sticking to the surface of the vegetation plate. The seedlings 53 can be vegetated. In addition, the suction airflow that is generated pulls the inserted root portion, so that sticking to the vegetation tray can also be prevented. Furthermore, since the seedlings are vegetated on the vegetation plate stacked above the vegetation tray, the vegetation plate can be carried to the hydroponic cultivation apparatus together with the vegetation tray after vegetation, which improves workability.

Further, in the above-mentioned root suction device for transplanting seedlings of the present invention,
It is preferable that the vegetation tray has a plurality of concave grooves extending in parallel.

  In the root suction device for transplanting seedlings of the present invention having such a configuration, smoothly replace the vegetation plate after seedling vegetation on the hydroponics aquarium without interfering with the root part, as it is in the hydroponics device Can be transferred. Furthermore, since the groove below the vegetation hole (the position where the root after the vegetation is arranged) has a predetermined width, the root does not collide with the wall surface of the groove during suction. That is, it is possible to prevent cutting of the root portion during seedling vegetation, to grow the seedling well, and to carry out hydroponics.

Further, in the above-mentioned root suction device for transplanting seedlings of the present invention,
It is desirable to suction in a direction substantially perpendicular to the axis of the vegetation hole.

  In the root suction device for seedling transplantation of the present invention having such a configuration, since the root portion is sucked in a direction substantially perpendicular to the hole axis of the vegetation hole, water or nutrient solution attached to the root portion to the suction machine side. It is possible to simplify the configuration of the entire device without sucking.

  According to the present invention, it is possible to provide a root suction device for transplanting seedlings, which simplifies transplantation of seedlings in hydroponic cultivation and can suitably improve the workability of cultivation.

It is a side view of the arrow line A in a), and Drawing 2 (c) is a back view of vegetation plate 9. 3 (a), (b) and (c) are diagrams showing the structure of the vegetation tray 11, FIG. 3 (a) is a plan view of the vegetation tray 11, and FIG. 3A is a cross-sectional view taken along arrow B in FIG. 3A, and FIG. 3C is a cross-sectional view taken along arrow C in FIG. As shown in FIGS. 2A, 2 </ b> B, and 2 </ b> C, the vegetation plate 5 cultivates the seedling 53 by holding the seedling 53 and immersing the root 55 of the seedling 53 in the nutrient solution in the hydroponic aquarium 17. It is a so-called foundation for performing.

  The vegetation plate 9 shown in FIG. 2A is a substantially rectangular plate-shaped component formed of a resin having a predetermined strength or a metal material having corrosion resistance, and is a through hole for holding the seedling 53. The vegetation hole 13 is provided. The vegetation hole 13 is a hole that penetrates from the front surface side to the back surface side of the vegetation plate 9, and the root portion 55 of the seedling 53 is inserted into this vegetation hole 13 to be positioned on the back surface side and hold the seedling 53 on the front surface side. To do.

  The number of the vegetation holes 13 provided in the vegetation plate 9 is preferably appropriately determined according to the sizes of the hydroponic cultivation device 51, the vegetation plate 9, and the vegetation tray 11 described later. It is preferable to be above the groove 15 provided in the vegetation tray 11 described later.

  In addition, the vegetation plate 9 of the present embodiment is provided with unevenness on the back surface side and a ventilation path 19 for moving the internal air from below to above when arranged in the hydroponic cultivation device 51. . The unevenness on the back surface is not always necessary, but it is effective because it serves as a guide when positioning the seedling 53, preventing the vegetation plate 9 from shifting, and locking with a roller conveyor (not shown) inside the hydroponic cultivation apparatus 51. is there. In addition, the vegetation plate 9 can employ a substantially similar aspect to the plate for hydroponic cultivation disclosed in JP-A-2018-7652.

  The vegetation of the seedlings 53 in the vegetation holes 13 may be performed via a substantially sponge-shaped medium 53a made of, for example, urethane resin. By doing so, the clearance between the vegetation hole 13 and the seedling 53 can be appropriately closed, and the seedling 53 can be held more reliably by the vegetation hole 13.

  As shown in FIGS. 3A, 3B, and 3C, the vegetation tray 11 is a component formed using a resin having a predetermined rigidity or a metal material having corrosion resistance. It can be formed by using a processing method such as injection molding or press molding depending on the material used, and a plurality of concave grooves 15 extending in parallel are formed.

  The recessed groove 15 that is recessed downward from the surface of the vegetation tray 11 in the height direction Z is a long groove that has a predetermined width dimension and depth dimension and that extends in the depth direction X. One end of the groove 15 in the depth direction X extends to the end edge of the vegetation tray 11 and communicates with the outside, and the other end forms the wall 25 with a slight distance from the end edge of the vegetation tray 11. The wall 25 is provided with a suction hole 27.

  A hollow communication portion 29 is provided on the other end side of the concave groove 15, and the communication portion 29 communicates with each suction hole 27 provided in all the concave grooves 15. In the present embodiment, the communication portion 29 is formed as a hollow box-like body and is a separate body different from the vegetation tray 11 and connected to the vegetation tray 11. However, this is not restrictive and, for example, a hollow cylinder. The vegetation tray 11 may be formed integrally with the vegetation tray 11.

  It is desirable that the width dimension and the depth dimension of the recessed groove 15 are substantially similar to each other and are set smaller than the width dimension and the depth dimension (cross-sectional dimension) of the hydroponic cultivation aquarium 17 included in the hydroponic cultivation device 51. Further, the length dimension of the groove 15 in the depth direction X is desirably determined according to the size of the vegetation plate 9, and in particular, may be appropriately determined in consideration of the position and spacing of the vegetation holes 13 for vegetating the seedlings 53. Good.

  The number of the grooves 15 formed is preferably determined according to the number of hydroponics aquariums 17 included in the hydroponic cultivation device 51, and the mutual arrangement intervals are substantially the same as those of the hydroponic aquariums 17. The same is preferable. It should be noted that a predetermined width as an edge portion is provided above the groove 15 formed at both ends in the width direction Y and above the other end of the groove 15 in the depth direction X. The smooth portion 31 is formed and contacts the vegetation plate 9.

  Further, a rising portion 33 having a predetermined height dimension is formed on the end portion of the vegetation tray 11, particularly on the outer side of the smooth portion 31. The rising portion 33 is a guide-like portion provided so that the vegetation tray 11 and the vegetation plate 9 are stacked in a predetermined state and maintained in this state. Moreover, even if the water level received by the root portion 55 of the seedling 53 is large and the water level exceeds the groove 15, it is possible to prevent the water from overflowing from the receiving portion 5 to the outside. The height dimension of the rising portion 33 may be appropriately determined in consideration of the plate thickness of the vegetation plate 9, the size of the groove 15, and the size of the entire vegetation tray 11.

3. Assembling Method of Root Suction Device 1 for Seedling Transplantation Next, the assembling method of the root suction device 1 for seedling transplantation according to the present embodiment will be described in detail with reference to FIGS. 4 and 5. FIG. 4 is a schematic side view of the assembled configuration of the root suction device 1 for transplanting seedlings according to the present embodiment. 5 (a) and 5 (b) are views showing the root suction device 1 for transplanting seedlings after assembly, and FIG. 5 (a) shows the root suction device 1 for transplanting seedlings after assembly. It is a top view and FIG.5 (b) is a side view of the arrow D in FIG.5 (a).

  As shown in FIG. 4, first, while aligning the positions of the vegetation holes 13 and the recessed grooves 15, the vegetation plate 9 is placed above the vegetation tray 11 and the both are stacked to form the suction structure 5.

  More specifically, the bottom surface of the vegetation plate 9 is brought into contact with the smooth portion 31 of the vegetation tray 11 while being placed between the rising portions 33 arranged on three sides of the vegetation tray 11. As a result, the vegetation plates 9 can be appropriately positioned with respect to the vegetation tray 11 and stacked on each other, and an unnecessary gap between the two can be reduced (in particular, see FIGS. 5A and 5B). .

  The suction device 3 is connected to the communication part 29 arranged in the vegetation tray 11 via the suction pipe 7, and connects the suction device 3, the suction pipe 7 and the suction structure body 5 to each other. Accordingly, by operating the suction device 3, it is possible to configure a suction path having the suction device 3, the suction pipe 7, the communication portion 29, the suction hole 27, each groove 15, and the vegetation hole 13 as routes. . The suction pipe 7 and the communication part 29 are connected to each other at two or more places of the communication part 29 while branching the suction pipe 7 from the suction device 3 so that the suction force in the communication part 29 does not generate a significant directionality. It is preferable to connect.

  Since a predetermined amount of air can be sucked into the suction path from one end of the recessed groove 15, the opening amount of each vegetation hole 13 and the opening of one end of each recessed groove 15 can be increased. By adjusting the amount and the amount, the amount of air sucked from each vegetation hole 13 can be adjusted. Further, if each suction hole 27 has a structure that can be opened and closed arbitrarily, only the concave groove 15 immediately below the vegetation hole 13 for vegetation of the seedling 53 can be communicated with the suction passage.

4. Method of Using Root Suction Device 1 for Seedling Transplantation Next, a method of using the root suction device 1 for seedling transplantation will be described in detail with reference to FIGS. 6 and 7. Drawing 6 (a) and (b) is a figure showing how to use root suction device 1 for seedling transplant, and Drawing 6 (a) is a mimetic diagram showing just before sucking seedling 53. FIG. 6B is a schematic diagram showing the seedling 53 after being sucked. Further, FIG. 7 is a schematic diagram showing a state in which the vegetation plate 9 after the vegetation is completed is transferred into the hydroponic cultivation device 51.

  The suction device 3 is operated after the above-described suction structure 5 is accurately configured, and the suction device 3, the suction pipe 7, the communication portion 29, the suction holes 27, the recessed grooves 15, and the vegetation holes 13 are used as routes. Start sucking air using the suction passage. The suction force may be adjusted according to the sizes of the vegetation holes 13 and the seedlings 53, and the adjustment can be easily performed mainly by changing the strength of the operation of the suction device 3. After confirming that the outside air is sucked from the vegetation hole 13 and the suction airflow is generated, the seedling 53 is moved above the desired vegetation hole 13 and the root 55 is gradually approached to this vegetation hole 13 (particularly in FIG. (See (a)).

  The root portion 55 is gradually influenced by the suction airflow (the influence of the air sucked from the vegetation holes 13) and is sucked toward the groove 15 side together with the air. After the suction of the root portion 55 is completed, it is confirmed that the seedling 53 itself is stably held in the vegetation hole 13, and then the seedling 53 is released. With the structure of the root suction device 1 for transplanting seedlings according to the present embodiment, the root portion 55 can suck in a direction substantially perpendicular to the hole axis of the vegetation hole 13. It is possible to simplify the configuration of the entire device without sucking up to the 3 side.

  By repeating the above procedure and completing the vegetation of the seedlings 53 in all the vegetation holes 13 or completing the vegetation of the desired number of the seedlings 53, the vegetation work on the placed vegetation plate 9 is completed.

  Even if the root 55 is slightly displaced from the vegetation hole 13 due to the suction airflow generated by the suction, the vegetation plate 9 is properly inserted into the vegetation hole 13 while preventing sticking to the surface of the vegetation plate 9 and the seedling 53 Vegetation can be done. Moreover, since the inserted root portion 55 is pulled by the suction airflow, sticking to the vegetation tray 11 can be prevented. Further, since the recessed groove 15 having a predetermined width is provided below the vegetation hole 13 (the position where the root 55 after vegetation is arranged), the root 55 does not collide with the wall surface of the recessed groove 15 during suction. That is, it is possible to prevent cutting of the root portion 55 during vegetation of the seedlings 53, to grow the seedlings 53 satisfactorily, and to carry out hydroponic cultivation.

  Subsequently, as shown in FIG. 7, the vegetation plate 9 on which the vegetation of the seedlings 53 has been completed by the above procedure is transferred into the hydroponic cultivation device 51. Since the suction structure 5 is configured by stacking the vegetation plate 9 and the vegetation tray 11 as described above, the configuration of the suction structure 5 is maintained after the vegetation of all the seedlings 53 is completed on the vegetation plate 9 ( Since the vegetation plate 9 and the vegetation tray 11 can be transported to the hydroponic cultivation device 51 in a stacked state, it is possible to prevent water or nutrient solution adhering to the root portion 55 from hanging down on the floor surface.

  In addition, the root suction device 1 for transplanting seedlings according to the present embodiment has the vegetation plate 9 to be actually used for cultivation in the hydroponic cultivation device 51 stacked on the vegetation tray 11 as described above, and the vegetation tray 11. Since the concave groove 15 of 11 is substantially similar to the hydroponic aquarium 17, the suction structure 5 after vegetation is completed is transported to the vegetation side of the hydroponic cultivation device 51, and the bottom surface of the vegetation plate 9 and the transfer destination. If the vegetation plate 9 is slid into the hydroponic cultivation device 51 after adjusting the height position with the upper end of the hydroponic aquarium 17 (upper end of the roller conveyor), the vegetation plate 9 is hydroponic aquarium. The work piece 17 can be smoothly transferred and transferred, and the workability is further improved.

  In the multi-stage hydroponic cultivation device 51 as shown in FIG. 7, there is a case where the seedlings 53 are grown by moving the seedlings 53 from the lower stage to the upper stage (transplanting the seedlings to the upper stage after predetermined growth) as the seedlings 53 grow. is there. For example, when performing a plurality of steps required for cultivation with the hydroponic cultivation apparatus 51, such as a sowing step, a seedling raising step, and a fixed planting step, the seeding step and the seedling raising step are performed in the lower to middle stages, and the fixed planting step is performed in the upper stage, and the above steps are transferred. Accordingly, the seedling 53 is moved and transplanted.

  Particularly in the transplantation accompanied by the transition to the planting process, the root 55 is long because the seedling 53 has grown to some extent, and it is very difficult to insert it into the vegetation hole 13 of the vegetation plate 9 of the transplant destination. Become. Therefore, the root suction device 1 for transplanting seedlings is more effective especially when transplanting the seedling 53 to the step where the root portion 55 is elongated.

  The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to these embodiments, and is not limited to the spirit and the teaching of the claims. There are improved examples and modified examples. It is easily understood by those skilled in the art that all such improvements and modifications are included in the technical scope of the present invention.

  The root suction device for transplanting seedlings according to the present embodiment simplifies transplantation of seedlings in hydroponic culture, and can suitably improve the workability of cultivation.
