Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plant cultivation apparatus and a plant cultivation facility provided with the plant cultivation apparatus.
[0002]
[Prior art]
Examples of cultivation means for planting and cultivating various plants include pots and planters filled with various media. In addition, there is a plant cultivation bed or the like that is maintained in a medium by a hard cover member such as a hard cultivation container or a plastic film, is generally formed larger than a planter used in home gardening, and is used in facility gardening.
[0003]
Conventionally, when installing these cultivation means in a plurality of rows, to avoid contact between plants cultivated in each cultivation means, and to ensure uniform lighting to them, they are spaced apart at predetermined intervals is doing. In addition, in the case of fruit and vegetables such as strawberries and tomatoes, it is necessary to frequently perform various operations such as pollination, harvesting and attracting stems, so these operations should be performed smoothly between adjacent cultivation means. It is necessary to secure a working space in consideration of the above. For this reason, in plant cultivation facilities, such as a greenhouse, it is substantially impossible to allocate the whole to a cultivation area, and the space which cannot grow a plant inevitably arises, such as the above-mentioned work passage. Under such circumstances, various ideas have been made to increase the yield without impairing workability in a limited cultivation facility.
[0004]
For example, in Patent Document 1, the cultivation means is supported on both ends of a string-like member wound around a pulley, or the cultivation means is supported on a string-like member suspended on both ends of a balance rod, and a framework that constitutes a greenhouse. A cultivation apparatus is disclosed in which the pulley and the balance rod are supported on a material and the cultivation means is normally arranged at a considerably high position in the greenhouse. When performing the work, one of the cultivation means is pulled down, and there is an advantage that the working space between adjacent cultivated plants can be reduced.
[0005]

[0006]
[Problems to be solved by the invention]
However, in the case of means using a pulley disclosed in Patent Document 1, two cultivation means are supported on a string-like member wound around the pulley. That is, since only two cultivation means are supported by one string-like member, the length and weight of the cultivation means supported by each string-like member are limited in order to achieve a balance. Can only support a relatively short length. For this reason, in Patent Document 1, for example, when cultivating a large number of plants in the inter-face-to-face direction or the side-to-side direction of the greenhouse, it is necessary to arrange a number of cultivation means in tandem, and the pulleys and the string-like members are Of course, only the number corresponding to the cultivation means arranged in the column is necessary. That is, since only one set of cultivation means can be supported for one set of pulleys and string-like members, the cultivation means arranged in the column direction cannot be moved up and down all at once. This also applies to the one using the balance rod disclosed in Patent Document 1. Therefore, even when the same operation is performed on all the cultivation means in a certain row, it is necessary to move the cultivation means adjacent in the vertical direction one by one, which is problematic in terms of workability.
[0007]
Moreover, what was disclosed by patent document 1 aims at positioning a cultivation means above a greenhouse in a normal state, and enabling it to pull down only when work is required. Therefore, the adjacent cultivation means supported by each end of the string-like member is basically always located at the same height, except when pulled down during work, and located at the same height. Therefore, it is not considered that the plants grown by the adjacent cultivation means are prevented from coming into contact with each other or that the sunlight condition on the other plant is prevented from being disturbed by one plant.
[0008]
Moreover, in patent document 1, only the structure where the pulley for moving a cultivation means up and down is directly attached to the frame material which comprises a greenhouse is disclosed. There is no problem when such a structure is used from the beginning of the construction of the greenhouse, but retrofitting a pulley or the like in a greenhouse that has already been constructed is problematic in terms of workability. Moreover, since it is only supported by the string-like member via the pulley or the balance rod, the interval between the cultivation means supported at each end of the string-like member is determined in advance depending on the size of the pulley or the length of the balance rod. It will be decided. Therefore, if you want to adjust the spacing between cultivation means in consideration of the size of the greenhouse, the type of plant to be cultivated, etc., you must replace the pulley or the balance rod itself with another size or length, which is inconvenient. It is.
[0009]
The present invention has been made in view of the above, and it is possible to move up and down a plurality of cultivation means in each row arranged along the inter-face-to-face or side-to-side direction of the greenhouse, thereby improving workability. It is an object of the present invention to provide a plant cultivation apparatus that can avoid contact with plants growing between adjacent cultivation means and obstruction of sunshine conditions. Moreover, this invention makes it a subject to provide the plant cultivation apparatus which can attach the member which moves a cultivation means up and down easily also by retrofitting. Moreover, this invention makes it a subject to provide the plant cultivation apparatus which can adjust the space | interval between a pair of cultivation means arrange | positioned so that vertical movement is possible as needed. Furthermore, this invention makes it a subject to provide the plant cultivation facility provided with the greenhouse suitable for arrange | positioning these plant cultivation apparatuses.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 is a front view showing a plant cultivation apparatus 1 according to the present embodiment, and FIG. 2 is a view showing an essential part thereof. As shown in these drawings, the plant cultivation apparatus 1 according to the present embodiment includes a rotating shaft 20 supported by a support member 10, pulleys 30 and 31 provided as a pair, and a hanging string. It has the member 40 and the drive member 50, and is comprised.
[0012]
As long as the support member 10 can rotatably support the rotating shaft 20 at a predetermined height, the support member 10 may be connected to an arbitrary frame material of the greenhouse 100 or may be erected on the ground in the greenhouse. It may be what you did. In this embodiment, as shown in FIGS. 1 and 2, a bar member or a pipe member spanned between the side surfaces of the greenhouse 100 is used as the support member 10. In this way, the ground is not erected on the ground, but supported by the support member 10 spanned between the side surfaces of the greenhouse 100 via the rotary shaft 20 and the like, as described later. The upper obstacle is eliminated, which is preferable for improving workability. When the support members 10 are provided along the direction between the side surfaces of the greenhouse 100, a plurality of the support members 10 are arranged at predetermined intervals in the direction between the wife surfaces of the greenhouse 100. Of course, depending on the size, shape, and the like of the greenhouse 100, the support member 10 can be disposed along the inter-wife surface direction. In this case, a plurality of support members 10 are disposed at predetermined intervals in the inter-surface direction. The
[0013]
As shown in FIG. 1, the support member 10 arranged in this manner is provided with the rotation shaft 20 at predetermined intervals in the longitudinal direction, and supports a plurality of cultivation means 200 and 210. That is, in this embodiment, each of the plurality of rotating shafts 20 supported by the support member 10 is configured to support the cultivation means 200 and 210, and the support member 10 is connected to the frame material of the greenhouse 100. In some cases, the load applied to the frame material via the support member 10 is very large. Therefore, it is necessary for the greenhouse 100 to have sufficient structural strength to support such a load. As shown in FIG. 1, the truss-like beam 110 is provided between the side surfaces of the greenhouse 100 or between the wife surfaces. It is preferable to use what was prepared. The truss-like beam includes not only a so-called truss beam but also a lattice beam.
[0014]
A bearing member 11 is attached to each of the support members 10 at predetermined intervals in the longitudinal direction of the support member 10. Moreover, since each support member 10 is arrange | positioned for every predetermined space | interval in the direction orthogonal to the longitudinal direction as mentioned above, the bearing members 11 attached to each adjacent support member 10 are the support member 10's. It is provided so as to be arranged linearly in a direction perpendicular to the longitudinal direction (see FIG. 2). And the rotating shaft 20 is rotatably supported by the bearing member 11 of each row | line | column arrange | positioned at linear form. As a result, the rotating shaft 20 is disposed along a direction orthogonal to the longitudinal direction of the support member 10 (see FIG. 2), and a plurality of the rotational shafts 20 are disposed at predetermined intervals along the longitudinal direction of the support member 10. (See FIG. 1).
[0015]
Pulleys 30 and 31 configured as a pair of two are arranged at positions spaced apart from each other by a predetermined interval with the rotating shaft 20 in between. The pulleys 30 and 31 may be arranged so as to face each other with the rotary shaft 20 as the center, and means for supporting the pulleys 30 and 31 is not limited. In the present embodiment, the pulleys 30 and 31 are rotatably attached to the support member 10 described above. In order to make the movement of the rotating shaft 20 smooth, it is preferable that the positions of the pulleys 30 and 31 in the vertical direction are slightly lower than the height of the rotating shaft 20. For example, as shown in FIGS. 1 and 2, the bearing member 11 that supports the rotating shaft 20 is provided so as to protrude above the support member 10, and the pulleys 30 and 31 are supported by the lower end of the support member 10. Can be provided.
[0016]
A plurality of pulleys 30 and 31 are provided at predetermined intervals along the longitudinal direction of the rotating shaft 20. In this case, the pulleys 30 and 31 may be disposed on all of the support members 10 adjacent along the longitudinal direction of the rotating shaft 20 or may be disposed every predetermined number. This also applies to the bearing member 11 that supports the rotary shaft 20 described above.
[0017]
A suspension string member 40 is wound around the rotary shaft 20 and the pulleys 30 and 31. Specifically, the middle part of the suspension string member 40 is wound around the rotary shaft 20 by one turn from the lower side, pulled out on both sides of the rotary shaft 20, wound around the pulleys 30 and 31 from the upper side, and the end portions 41, 42 is provided to hang downward. When the suspension string member 40 is wound around the rotary shaft 20 a plurality of times, the suspension string member 40 may be overwound when the rotary shaft 20 is rotated, and the movement may be deteriorated. It is preferable that only the rotation is wound.
[0018]
The cultivation means 200 and 210 are supported on the end portions 41 and 42 of the suspension string member 40, respectively. That is, one of the cultivation means 200 is arranged in a row in the row of the end portions 41 on one side of the hanging string members 40 arranged at predetermined intervals in the longitudinal direction of the rotating shaft 20 (the depth direction in FIG. 1). And the other cultivation means 210 is similarly supported in a column in the row of the end portions 42 on the other side. The cultivation means 200 and 210 are, for example, long box-shaped members having a length of about 0.5 to 5 m and a width of about 5 to 50 cm, and are formed of cloth, plastic, metal, etc., and filled with a medium inside. Possible cultivation containers can be used. However, the present invention is not limited to this, and for example, a small planter or the like used in pots or home gardening can be individually supported by the hanging string member 40 described above. Moreover, a plurality of pots, planters, and the like can be placed on a placing member such as a tray having an appropriate length and width and supported as a cultivation means.
[0019]
Moreover, although the string member 40 for suspension is good also as a structure which connects the above-mentioned cultivation means 200 and 210 directly to each edge part 41 and 42, a length adjustment means is connected to each edge part 41 and 42, It is preferable that the cultivation means 200 and 210 are connected via the length adjusting means. As described above, the cultivation means 200 and 210 are separately supported by the row of the end portions 41 on one side and the row of the end portions 42 on the other side of the hanging strap member 40, respectively. Although it is different, the total length of each row of the cultivation means 200 and 210 is usually set to be about several tens of meters to one hundred meters. Therefore, if the cultivation means 200 and 210 of each row meander up and down when viewed along the longitudinal direction, the drainage direction of the cultivation means 200 and 210 is not constant, and the cultivation means 200 and 210 There is a risk of drainage collecting at the bottom. In addition, there is a possibility that the liquid supply may be biased. On the other hand, it is difficult to arrange the cultivation means 200, 210 substantially horizontally or at a fixed inclination angle in the longitudinal direction (depth direction) only by connecting to the end portions 41, 42 of the hanging string member 40. . For this reason, it is preferable to provide a length adjusting means as described above. The length adjusting means is not limited, but can be connected inexpensively and easily. Therefore, the turnbuckle 45 is used as shown in FIG. 2 and is connected to the end portions 41 and 42 of the suspension string member 40. It is preferable to do.
[0020]
Moreover, the string member 40 for suspension is wound around the rotating shaft 20 and wound around the pulleys 30 and 31 as described above, and supports the cultivation means 200 and 210 on the end portions 41 and 42, respectively. The end portions 41 and 42 of the suspension string member 40 are suspended vertically from the pulleys 30 and 31. For this reason, the interval between the cultivation means 200 and 210 is determined by the interval between the pulleys 30 and 31. In order to increase the cultivation density in the greenhouse 100, it is desirable that the intervals between the cultivation means 200 and 210 be as close as possible. However, if they are too close together, the plants growing in the cultivation means 200 and 210 are adjacent to each other. There is a risk of contact. Accordingly, even when the cultivation means 200 and 210 are positioned in a substantially horizontal state, the distance between the pulleys 30 and 31 is adjusted so that the adjacent plants do not come into contact with each other.
[0021]
The means for rotating the rotary shaft 20 is arbitrary, but in this embodiment, as shown in FIG. 2, a drum 51 connected to one end of each rotary shaft 20 via a gear mechanism 53, and the drum 51 A driving member 50 composed of a chain 52 to be hung is used. That is, when the chain 52 is pulled down in one direction, the rotary shaft 20 rotates in one direction, and when the chain 52 is pulled down in the other direction, the rotary shaft 20 rotates in the other direction. The drive member 50 is not limited as long as the rotary shaft 20 can be rotated. For example, a handle (not shown) connected to the gear mechanism 53 is used instead of the drum 51 and the chain 52. It can also be used. In addition to the manual type, a motor (not shown) may be connected to the gear mechanism 53 to be an electric type. Furthermore, in the above description, each drive member 50 is disposed corresponding to each of the rotation shafts 20, but a configuration in which a plurality of rotation shafts 20 can be simultaneously controlled by one drive member may be employed. For example, by providing a pinion (not shown) on each rotating shaft 20 and arranging a rack (not shown) that meshes with each pinion in a direction perpendicular to the rotating shaft 20, and operating this rack manually or by a motor. The plurality of rotating shafts 20 can be controlled together. Further, a shaft (not shown) is arranged orthogonal to the rotating shaft 20, and a worm and a worm gear are arranged at the intersection of the shaft and the rotating shaft 20, and the shaft is connected to a motor for rotation. It can also be set as the structure which rotates the axis | shaft 20. FIG.
[0022]
Moreover, it is preferable to provide the rotating shaft 20 so that it can stop in the state rotated by predetermined amount. For example, a brake mechanism (not shown) may be connected to the gear mechanism 53 connected to the rotary shaft 20 so that the rotation in the reverse direction is prevented when the operating hand is released from the chain 52. it can. Further, when the chain 52 is pulled down by a predetermined amount, it can be configured to be hooked on an arbitrary member to prevent the rotation shaft 20 from rotating backward. With such a configuration, when the rotary shaft 20 is rotated by the driving member 50 and stopped in a state where the rotary shaft 20 is rotated by a predetermined amount, the cultivation means 200 and 210 of each row supported by the single rotary shaft 20 are arranged. It can be held in a different state.
[0023]
According to the plant cultivation apparatus 1 of this embodiment, for example, the cultivation means 200 and 210 are installed in the greenhouse 100 in a state where the cultivation means 200 and 210 are substantially horizontal. In the case of a general plant cultivation apparatus in which each cultivation means is installed in the greenhouse at the same height, instead of a plant cultivation apparatus that can move up and down as in this embodiment, the work is hindered between the cultivation means. It is necessary to secure a working space of a predetermined width that does not allow it. However, according to this embodiment, a set of cultivation means 200 and 210 supported by a certain rotation shaft 20 and another set of cultivation means supported by another adjacent rotation shaft 20. It is not necessary to provide an interval corresponding to the work space required at the time of work in advance between 200 and 210, and the plant can be positioned so close that the plants do not contact each other.
[0024]
When work is performed on the cultivation means 200 and 210 of the plant cultivation apparatus 1 installed as described above, the chain 52 is pulled down in a predetermined direction. Thereby, since the rotating shaft 20 rotates in a predetermined direction, as shown by an imaginary line in FIG. 1, one of the cultivation means 200 and 210 (for example, the cultivation means 200) rises and the other (for example, the cultivation means 210). ) Is relatively lowered. For this reason, a work space is secured below the raised cultivation means 200. At this time, by rotating two adjacent sets of rotating shafts 20 in opposite directions, one cultivation means 200 belonging to one set and the other cultivation means 210 belonging to another set adjacent to the one pair. Since both rise, a larger work space can be secured. Thereby, according to this embodiment, compared with the general plant cultivation apparatus which installs each cultivation means in the greenhouse at the same height, it is the space | interval (the code | symbol X of FIG. 1) between cultivation means which should be ensured previously. The interval shown) can be reduced, and the cultivation density in the greenhouse can be greatly increased.
[0025]
Moreover, in the case of this embodiment, a plurality of the cultivation means 200 and 210 in each row are arranged in a column, and a plurality of them are provided at predetermined intervals along the longitudinal direction of the rotating shaft 20. It is supported by a pair of pulleys 30,31. For this reason, if the chain 52 which is the drive member 50 is operated and the rotating shaft 20 is rotated, for example, all the cultivation means 200 which belong to one row will be raised at a time, and all the cultivation means 210 which belong to the other row will be raised. Can be raised at once. That is, since the cultivation means 200, 210 can be moved up and down at once along the longitudinal direction of the rotary shaft 20, the cultivation means 200, 210 belonging to each row can be easily adjusted to the required height, Thus, there is no need to individually adjust the height of a plurality of cultivation means connected in the column direction.
[0026]
Moreover, in this embodiment, since the rotating shaft 20 can be maintained by arbitrary rotation amount, ie, the up-and-down height of the cultivation means 200 and 210 can be maintained at each arbitrary height, according to the kind of plant to grow. It is possible to work by adjusting the height to a worker's comfortable working posture. Moreover, by making the cultivation means 200 and 210 the same height, basically, the sunshine conditions for the cultivation means 200 and 210 can be made equal, but on the other hand, the cultivation means 200 and 210 are the same. If the height is adjusted, it may not be possible to obtain substantially uniform sunshine conditions. For example, when the other is likely to be shaded by the growth of the plant, according to this embodiment, in such a case, the rotating shaft 20 is arbitrarily rotated to move the upper and lower portions of the cultivation means 200, 210. By making the heights different, substantially uniform sunshine conditions can be ensured.
[0027]
In addition, the kind of plant planted by the cultivation means 200 and 210 of the plant cultivation apparatus 1 of the present embodiment is not limited, and fruit vegetables such as tomatoes, melons, and strawberries, and beans such as green beans and green peas. Etc. can be cultivated. In addition, leek, parsley, asparagus and the like can be cultivated. In particular, in the case of tomato, in normal cultivation, for the convenience of harvesting work, it is necessary to perform an attracting work to increase the length of the stem part extending sideways along the surface of the medium etc. according to the growth. In the case of the embodiment, once adjusted to hang down from the cultivation means 200 and 210 and then extend upward, the cultivation means 200 and 210 are then raised according to the growth, thereby substantially reducing the stem portion. Since it can be loosened in a U shape, it is not necessary to extend the stem part to the side. Moreover, in the case of a strawberry, the seedling raising method which grows a seedling downward from the cultivation means 200 and 210 is known, but according to this embodiment, by raising the cultivation means 200 and 210 according to the growth of the seedling. The seedling of one of the cultivation means 200 and 210 can be prevented from coming into contact with the ground. Therefore, fruit vegetables such as tomatoes and strawberries are particularly suitable as plants to be cultivated. In addition, since the other row | line | column will fall if the cultivation means 200,210 raises one row | line | column, when raising according to growth as mentioned above, it grows with the cultivation means of the other row | line | column which descend | falls. It is necessary to be careful not to disturb the plants.
[0028]
The plant cultivation apparatus of the present invention is not limited to the above-described embodiment. In the above embodiment, the bearing member 11 is fixed to the support member 10 fixedly disposed in the greenhouse 100, the rotating shaft 20 is disposed, and two pairs of pulleys 30 and 31 can be rotated on the support member 10. I support it. Therefore, the positional relationship between the pulleys 30 and 31 with respect to the rotating shaft 20 is fixed when these are constructed. However, as a result of actual cultivation for a predetermined period, the gap between the pulleys 30 and 31 is adjusted, the distance between the cultivation means 200 and 210 is shortened, and the cultivation density is increased, or conversely, cultivation is performed according to the growth of the crop. In some cases, it may be desirable to increase the distance between the means 200 and 210. Therefore, as shown in FIG. 3, when attaching the pulleys 30 and 31 to the support member 10, the insertion holes 10 a into which the support shafts 30 a and 31 a of the pulleys 30 and 31 are inserted are laterally long and the holes It is preferable that the wall is formed in a slit shape with irregularities so that the support positions of the support shafts 30a and 31a can be adjusted by sliding. Since the cultivation means 200 and 210 are supported by the end portions 41 and 42 of the suspension string member 40 that is suspended vertically from the pulleys 30 and 31, the horizontal distance of the pulleys 30 and 31 can be adjusted. Thus, the distance between the cultivation means 200 and 210 can be adjusted.
[0029]
Further, as shown in FIG. 4, each pulley 30, 31 is formed of, for example, a plate-like body having an L-shaped cross section so that it can be easily attached to the support member 10 and can be retrofitted. It is preferable that these are supported by a pulley support plate 300 and configured as one pulley mounting unit. Also in this case, it is preferable that the pulley support plate 300 has a configuration in which the axial support positions of the pulleys 30 and 31 can be adjusted by forming a slit 300a in the horizontal direction. Further, it is preferable that the bearing member 11 is also integrally provided in the vicinity of the upper portion of the central portion between the two pulleys 30 and 31 of the pulley support plate 300. This makes it easier to retrofit existing greenhouses.
[0030]
