Description

The present invention relates to a plant cultivation device in which a cultivation bed is rotatably supported on a predetermined pedestal via an arm member and a rotating shaft, and plants are cultivated using a space in a plant cultivation facility. be.

With recent plant cultivation equipment, it is important to increase the number of seedlings (number of beds) planted as much as possible in the limited space of a plant cultivation facility such as a greenhouse, and to increase the yield by giving plants on each cultivation bed equal sunlight at all times. There is a need to ensure uniform and good growth by applying light, and to be able to increase the number of seedlings planted as much as possible in a limited space while still being able to secure the necessary work space when needed.

Based on these circumstances, the inventors of the present application rotatably support a pair of left and right cultivation beds on a predetermined pedestal via an arm member and a rotating shaft in a plant cultivation facility such as the one described above. By rotating the rotation shaft using the rotation operation means, the pair of left and right cultivation beds are maintained both in a horizontal state in a first state and in a vertical state in which one is maintained upward and the other is downward. We have filed a patent application for a plant cultivation device that can be arbitrarily shifted to the state described in No. 2 (see Patent Document 1).

In a plant cultivation device having such a configuration, when the pair of left and right cultivation beds are maintained horizontally, the cultivation beds of the plurality of rows of cultivation devices are brought close to each other, thereby increasing the number of plants to be planted (number of beds). In addition, the cultivation bed of each cultivation device is evenly exposed to sunlight, achieving uniform and good growth conditions. Furthermore, when the pair of left and right cultivation beds are maintained vertically, a necessary working space is formed between the plurality of rows of cultivation devices. Therefore, each of the above demands can be met.

In the case of this plant cultivation device, the rotating shaft that rotatably supports the pair of left and right cultivation beds via the arm member is quite long (for example, about 25 m in total length), and the same A plurality of sets (for example, 4 sets) of frames are installed at a predetermined interval (for example, 6 m intervals) between both longitudinal ends of a long rotation shaft, and the long rotation is performed using a bearing provided at the center of the upper part of each frame. While the shaft is rotatably supported, a pair of front and rear arm members are provided between adjacent mounts, and a pair of left and right cultivation beds are provided between both ends of the front and rear pair of arm members, and are rotatably supported. Each of the multiple sets of frames has a gate-shaped structure, for example, with two legs on the left and right, and the two legs are placed on the installation surface in the cultivation facility with a foundation made of concrete, etc., and then leveled. It is installed at the required height by removing it.

As the long rotating shaft, a single unit (one piece) or a connected structure (additional structure) is arbitrarily adopted. At one end of this long rotating shaft, a manual rotation operation means equipped with, for example, a deceleration mechanism is provided. The arm member is rotated from a horizontal state to a vertical state and from a vertical state to a horizontal state.

As a result, the pair of left and right cultivation beds, which are suspended between both ends of the front and rear pair of arm members so as to be relatively rotatable, are also rotationally displaced from the horizontal state to the vertical state and from the vertical state to the horizontal state.

Patent No. 7034358

By the way, as in the plant cultivation apparatus of Patent Document 1, the rotation shaft is quite long, and a pair of front and rear arm members in multiple rows, a pair of front and rear arm members, is operated using a manual rotation operation means equipped with a deceleration mechanism. In order to smoothly rotate the rotating shaft that supports the pair of left and right cultivation beds supported between both ends of the arm member from one end to the other end without shaking, it is necessary to rotate the rotating shaft from one end to the other end smoothly. The entire structure must be supported in a straight, coaxial state by multiple bearings, that is, it must not be displaced in either the horizontal or vertical direction, and must be maintained as completely coaxial as possible. .

However, each frame in multiple rows has a gate-shaped structure with two legs on the left and right, and the connection part (bearing support part) that interconnects the two legs on the left and right and their upper ends is In the case of a completely fixed structure, the installation position and level adjustment must be performed for each of the multiple rows of frames as a whole, making the installation work extremely troublesome. Furthermore, pouring concrete foundations is itself a troublesome work, and there are also circumstances in which it is desirable to avoid pouring foundations in the field areas of plant cultivation facilities such as greenhouses as much as possible.

Therefore, for example, it may be possible to support the two legs of each multi-row mount at the required height by driving it into the soil of the installation surface (field site) to a predetermined depth, without needing to cast the foundation. . However, even in that case, if the connecting part (bearing support part) that interconnects the two left and right legs and their upper ends is a completely fixed structure, it is difficult to drive the legs, and there is no need for foundation work. and proper installation is difficult.

Under these circumstances, it has been found that there is still a need for improvement in the frame structure of the invention of the earlier application.

The present invention has been made in order to solve such problems, and includes a connecting member (bearing support part) that connects the two left and right legs that constitute the pedestal and the upper ends of the two left and right legs. By making the connecting parts relatively movable until the final fixed state, it can be used not only when performing foundation work, but also by simply driving the two left and right legs into the soil to a predetermined depth and supporting it at the required height. It is an object of the present invention to provide a plant cultivation device equipped with a mount that can easily adjust the position in both horizontal and vertical directions.

The present invention has the following configuration as a means for solving the above problems.

(1) Means for solving the problem of the invention of claim 1 The plant cultivation device of the invention of claim 1 includes a plurality of mounts arranged in parallel at a predetermined interval in a predetermined direction, and a plurality of mounts arranged on the upper part of the plurality of mounts. a plurality of bearing parts, a rotary shaft rotatably supported while penetrating each bearing hole of the plurality of bearing parts, and the rotary shaft between mutually opposing bearing parts of the plurality of bearing parts. Each arm member is located on the end side of each bearing and is supported in the middle part in an orthogonal state, and rotates in the vertical direction according to the rotation of the rotation axis, and both ends of each arm member are rotatable relative to each other. and a pair of cultivation beds suspended from each other, and by rotating the rotation shaft with a predetermined rotation means, the pair of cultivation beds suspended from both ends of each of the arm members in a relatively rotatable manner. A plant cultivation device that displaces a mutually horizontal first hanging state and a mutually perpendicular or nearly vertical second hanging state, wherein the plurality of mounts each have a position of a bearing hole of the bearing part. It is characterized in that it is constructed with a bearing hole position adjustment structure that can be arbitrarily adjusted in the horizontal and vertical directions so that the rotating shaft can linearly pass through the shaft in a coaxial state.

According to such a configuration, a rotating shaft that is rotatably supported by penetrating the bearing hole of the bearing section on each of the multiple mounts installed in parallel at a predetermined interval in a predetermined direction is rotated. By doing so, the pair of left and right cultivation beds, which are hung so as to be relatively rotatable at both ends of the pair of front and rear arm members between each mount, can be changed from a mutually horizontal first suspended state to a mutually vertical or nearly vertical suspended state. It can be arbitrarily displaced into the second suspended state or vice versa.

Therefore, as in the case of the previous application, when a plurality of rows of plant cultivation devices having the above configuration are installed adjacent to each other in the left and right direction in a predetermined plant cultivation facility, the pair of left and right cultivation beds are placed in the horizontal first By maintaining the hanging condition, it is possible to effectively utilize the space within the cultivation facility and increase the number of planted plants (number of beds).In addition, each of the pairs of left and right cultivation beds can be uniformly exposed to sunlight. can be irradiated, so growth efficiency can be improved. On the other hand, when the pair of left and right cultivation beds are maintained in a second hanging state that is perpendicular or nearly perpendicular to each other, a necessary working space can be formed between the plurality of rows of plant cultivation devices in the left and right direction. Furthermore, by locating the cultivation bed that requires work on the upper side of the pair of left and right cultivation beds, it is possible to work in a comfortable working posture. This second suspended state may be shifted to a completely vertical state in which the pair of cultivation beds are vertically located, but it is also possible to shift the pair of cultivation beds to a completely vertical state in which they are located vertically, or to a near-vertical state where the cultivation beds are tilted to some extent from the same vertical state (a state in front of the vertical). ), and can achieve almost the same purpose. This also allows the height of the cultivation bed located on the upper side to be adjusted.

In the plant cultivation device of the present invention, in the structure of the plant cultivation device, a bearing portion is attached to the upper portion, and each of the plurality of frames supporting the rotating shaft via the bearing portion is connected to the bearing portion of the bearing portion. A bearing hole position adjustment structure is provided that can arbitrarily adjust the position of the hole in the horizontal and vertical directions so that the rotating shaft can linearly pass through the bearing hole in a coaxial state.

Therefore, the positions of the bearing holes of the respective bearings on the plurality of frames that rotatably support the rotating shafts are adjusted so that the rotating shafts are aligned in a straight line using the bearing hole position adjustment structure of the frames. Suitably adjusted horizontally and vertically to allow penetration. As a result, even when the legs of each pedestal are driven into the installation surface, the positions of the bearing holes of the plurality of bearing parts on the plurality of pedestals can be aligned on the same axis. Therefore, it is easy to insert the rotating shaft into each bearing hole, and the supported rotating shaft also rotates smoothly.

(2) Means for solving the problem of the invention of claim 2 The plant cultivation device of the invention of claim 2 is the plant cultivation device of the invention of claim 1, in which the plurality of bearings are arranged in the front and rear directions with respect to each corresponding frame. The bearing hole is tiltably attached to the bearing hole, and the opening surface of the bearing hole can be adjusted along the vertical direction.

According to such a configuration, not only can the positions (center positions) of the bearing holes of the plurality of bearing parts on the plurality of frames be aligned on the same axis, but also the positions (center positions) of the bearing holes of the plurality of bearing parts on the plurality of frames can be aligned. Since the opening surface of each bearing hole can be adjusted along the vertical direction, it is possible to ensure that the opening surface of each bearing hole is perpendicular to the rotation axis extending in the horizontal direction. As a result, the center axes of the bearing holes of the respective bearing portions more reliably match with each other, making it possible to support the rotating shaft in a mutually concentric state. Therefore, the rotating state of the rotating shaft also becomes smoother.

(3) Means for solving the problem of the invention of claim 3 The plant cultivation device of the invention of claim 3 is the plant cultivation device of the invention of claim 1 or 2, in which each of the plurality of bearings is arranged in the axial direction of the rotating shaft. It is characterized by a flat structure.

As shown in the configuration of the plant cultivation device of the invention of claim 2, the plurality of bearings provided at the center of each of the plurality of mounts can be tilted (raised and lowered) in the front and rear directions with respect to each mount. It is preferable that the opening surface of the bearing hole is adjustable along the vertical direction. By doing so, it is possible to ensure that the opening surface of each bearing hole is perpendicular to the rotating shaft extending in the horizontal direction, and the center axes of the bearing holes of each bearing part are more reliably aligned. This allows the rotating shafts to be supported in a mutually concentric state. Therefore, the rotating state of the rotating shaft also becomes smoother.

However, even if such a configuration is not used, if the respective bearings are configured to be flat in the axial direction of the rotating shaft, even if there is a certain degree of inclination in the front-rear direction, the influence of the bearings will be affected. is small and can maintain smooth rotation of the rotating shaft. Of course, when combined with the configuration of the invention of claim 2, the rotating state of the rotating shaft can be made even smoother.

As a result of the above, in the plant cultivation device of the present invention, it is easy to adjust the level of each of the plurality of frames arranged in a predetermined direction at a predetermined interval, and the bearing hole of the bearing part of each of these frames can be adjusted easily. Even when a long rotating shaft penetrates and is rotatably supported, it can be reliably supported in a concentric state. Therefore, the rotation of the pair of left and right cultivation beds suspended via the pair of front and rear arm members and the pair of front and rear arm members becomes smooth, and the rotation operation by the one end side rotation operation means is also facilitated.

The leg portion 24 includes a short first metal pipe 24a for attaching the bearing portion 21, and long second and third metal pipes 24b and 24b that support both ends of the first metal pipe 24a. and bracket members 27, which engage and fix both ends of the first metal pipe 24a to predetermined positions on the upper end sides of the second and third metal pipes 24b, 24b. The second and third metal pipes 24b and 24b are installed in a vertical state at a desired height by driving them into the ground of the equipment installation surface of the plant cultivation facility at equal intervals and parallel to each other to a predetermined depth. be done. Then, the bracket members 27, 27 are used between the upper ends of the second and third metal pipes 24b, 24b, which are parallel to each other and spaced at equal intervals, so that the first metal pipe 24a is horizontally crossed and perpendicular to each other. Both ends are engaged and fixed.

As shown in FIGS. 9 and 11, for example, the bracket members 27, 27 include a main body member 27a that is V-shaped in side view and has an enlarged opening side, and a main body member 27a that has an opening side engaging rib on the inside of the main body member 27a. The wedge member 27b is forcibly driven in from the opposite direction. Then, the bracket members 27, 27 are used between the upper ends of the second and third metal pipes 24b, 24b to intersect both ends of the first metal pipe 24a, and using a spirit level, After confirming that the first metal pipe 24a is in a horizontal state, the wedge member 27b is driven in to ensure engagement and fixation. After fixing, as required, as shown in FIG. 11, drilling screws 29 are screwed into the front portions of the curved portions of the bracket members 27, 27 for final fixation. This makes it possible to adjust the height of the first metal pipe 24a to which the bearing part 21 is attached and to horizontally attach the first metal pipe 24a between the upper ends of the second and third metal pipes 24b and 24b. Realized.

<About the structure of the bearing part 21>
6 to 8 and 10 show the configuration of a portion of the bearing portion 21 that rotatably supports the above-mentioned rotating shaft 3 in a direction around the axis.

That is, the bearing part 21 of this embodiment includes a bearing body plate 22 having a semicircular upper part 22a and a rectangular lower part, and a bearing body plate 22 that corresponds coaxially to the semicircular part on the upper part 22a side of the bearing body plate 22 and is provided on the outer periphery. A donut-shaped ring plate 21a is connected and integrated at a predetermined interval through six connecting shafts, and the six rings connect the ring plate 21a and the upper part 22a of the bearing main plate 22. Six roller members 21b, 21b, etc. are rotatably and loosely fitted around the outer periphery of the connecting shaft, and the roller members 21b, 21b, and so on are inscribed inside these six roller members 21b, 21b, and held so as to be freely rotatable. It consists of a circular rotating plate 21c with a predetermined thickness and a square rotating shaft penetration hole (bearing hole) 30 provided in the center of the rotating plate 21c (see FIGS. 7 and 8). The end of the rectangular lower part of the bearing body plate 22 is bent at right angles in the horizontal direction by a predetermined width to form a flange part 22b for attachment to the first metal pipe 24a on the leg part 24 side described above. . The flange portion 22b for attachment to the first metal pipe 24a on the leg portion 24 side is attached to a shaft that is fixed to the first metal pipe 24a of the leg portion 24 via a pair of left and right U-shaped rods 26, 26. It can be attached to the upper surface 23a of the member 23 via bolts and nuts 25, 25.

As shown in FIGS. 7 and 10, the bearing mounting member 23 has a hat-shaped cross section that is long in the left-right direction as a whole, and has a mounting portion for the bearing body plate 22 at the center of the upper side, and holes on the left and right sides of the lower side. The first metal pipe 24a has flange portions 23b, 23b that come into contact with the first metal pipe 24a. The flange parts 23b, 23b are long in the front and back, respectively, and elongated holes 23c, 23c, 23c, 23c of a predetermined width are provided at two places on the front end side and the rear end side, respectively, for fitting the U-shaped rods 26, 26. It is being These elongated holes 23c, 23c, 23c, 23c are connected to the straight connecting ends 26a, 26a, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, 26b, etc. 26a, 26a, 26a are fitted and inserted, nuts 26b, 26b, 26b, 26b are screwed to the connecting end portions 26a, 26a, 26a, 26a, and the portions are screwed and fastened, thereby forming the shaft receiving member 23. is fixed to the upper part of the first metal pipe 24a (see FIGS. 7 and 8).

In this way, when the bearing mounting member 23 that supports the bearing part 21 in the vertical direction is connected and fixed to the first metal pipe 24a of the leg part 24 of the frame 2 via the U-shaped rods 26, 26, Since the bearing part 21 can be freely slid in the left and right directions along the first metal pipe 24a until it is fixed, the position of the bearing part 21 alone in the left and right direction can be adjusted, and the position can be adjusted at a predetermined level. Even if it is tightened, for example, as shown by the arrow in FIG. 8, after determining the position in the left and right direction, the first metal pipe 24a is semi-fixed and rotated to the front or back at a desired angle. be able to. That is, the undulation angle of the bearing portion 21 with respect to the longitudinal direction (front-back direction) of the rotation shaft 3 can be finally adjusted independently of the vertical state of the leg portion 24.

That is, in the case of this embodiment, as described above, on the leg portion 24 side, the second and third metal pipes 24b, 24b, 24b, 24b, etc., which are a pair of left and right supports, are first stretched with strings. etc., and install it as vertically as possible with a predetermined left and right width and a predetermined front and rear spacing (drive-in installation). Then, the first metal pipes 24, 24, etc. that support the bearing part 21 are connected to the second and third metal pipes 24b, 24b, 24b, 24b, etc., which are the pair of left and right supports. By engaging and fixing the first metal pipe 24a using the bracket members 27, 27, it is possible to adjust the vertical height (ground clearance) and lateral position (horizontal engagement position) of the first metal pipe 24a. Therefore, the state in which the first metal pipes 24, 24, etc. are supported by the legs 24, 24, etc. of the plurality of frames 2, 2, etc., which are arranged in series at predetermined intervals in the front-rear direction, is different from that of the first metal pipes, respectively. The pipes 24a, 24a are set at a common height and lateral position as a whole.

However, even if the first metal pipes 24, 24, . . . as bearing support members are at the same height and horizontal position as a whole, the first metal pipes 24a, 24a, . * are separate pieces, and the second and third metal pipes 24b, 24b, 24b, 24b, etc. are not necessarily driven in an accurate vertical state. Therefore, in order to attach the bearing portions 21, 21, etc. to the intermediate portions in the left-right direction of each of the first metal pipes 24a, 24a, etc. via the bearing mounting members 22, 22, etc. in an accurate vertical state, the first It is also necessary to adjust the vertical position of the bearing parts 21, 21, etc. in relation to the metal pipes 24a, 24a, .

As described above, the bearing mounting member 23 that supports the bearing part 21 in the vertical direction is connected and fixed to the first metal pipe 24a of the leg part 24 of the pedestal 2 via the U-shaped rods 26, 26. Then, such requests can be reliably met.

<About the support structure of the rotating shaft 3 by the bearing part 21>
In this embodiment, the elongated rotating shaft 3 is, for example, a rectangular steel pipe member with a square cross section. The rotating shaft 3 made of the rectangular steel pipe member is inserted into the rotating shaft penetrating hole ( (corresponding to the bearing holes in the claims) 30, 30, etc., in a coaxial horizontal state and rotatably supported. In this case, the shape of the rotating shaft insertion holes 30, 30, etc. in each of the rotating plates 21c, 21c, etc. naturally corresponds to the external shape of the rotating shaft 3, but the inner diameter dimension is As an example, it is formed to have a larger dimension with a predetermined gap relative to the outer diameter dimension of the rotating shaft 3. A predetermined gap is sufficient for engagement in the rotational direction between the rectangular rotating shaft 3 and the rectangular rotating shaft penetration holes 30, 30, etc., and the rotation of the rotating shaft 3 in this embodiment is Since the rotation is temporary and slow, there is no risk of generating noise during rotation even if there is a predetermined gap between the mutually inserted portions.

In particular, in this embodiment, a continuous long rotating shaft 3 is supported between the bearing parts 21, 21, etc. of a plurality of frames 2, 2, etc., which are located at a considerable distance (25 m) in the front and rear direction. Therefore, if there is a horizontal or vertical positional shift in the rotating shaft insertion holes 30, 30, which are bearing holes, it will be difficult to insert the long rotating shaft 3 straight through, and it will be difficult to insert the long rotating shaft 3 straight through. Even if it is inserted, there is a possibility that a cross-direction force will be generated between the rotary shaft insertion holes 30, 30, and the rotary shaft 3, and the rotary shaft 3 will not rotate smoothly.

However, as described above, the rotating shaft through holes 30, 30, etc. in the bearing portion 21 are formed in the rotating plate 21c, which is thin in the axial direction of the rotating shaft 3, and the rotating shaft through holes 30, 30... By making the inner diameter of ... a predetermined dimension larger than the outer diameter of the rotating shaft 3, not only will it be easier to insert the rotating shaft 3, but there will also be a small amount of space in the rotating shaft penetration holes 30, 30..., which are bearing holes. Even if there is a positional shift in the horizontal or vertical direction, no cross-direction force is generated between the rotating shaft 3 and the rotating shaft 3, and smooth rotation can be achieved. Further, in the case of this embodiment, not only the rotating plate 21c in which the rotating shaft penetration holes 30, 30, . . . Both the ring plate 21a and the ring plate 21a are formed of flat plate members. Therefore, it becomes easier to realize the above effect.

Further, the undulation angle of the bearing portion 21, which is flat as a whole and small in dimension in the direction of the rotating shaft 3, is adjustable as described above. Therefore, in the case of the same configuration, even if the length of the rotating shaft 3 becomes considerably long, easy insertion and smooth rotation can be realized.

<Configuration of arm members 4, 4>
The arm members 4, 4 provided at both front and rear end sides between the mutually opposing mounts 2, 2 of the plurality of mounts 2, 2, etc. are shown, for example, in FIGS. 2 and 4 to 6. As shown in FIG. (not shown). By inserting the rotary shaft 3 into the rotary shaft penetration hole, the rotary shaft 3 is supported in the space above the mounts 2, 2, and the vertical surface around the rotary shaft 3 changes according to the rotation of the rotary shaft 3. It can be rotated clockwise or counterclockwise along.

<Configuration of a pair of left and right cultivation beds>
On the other hand, in the case of this embodiment, a pair of left and right cultivation beds are suspended from the right and left ends of each of the arm members 4, 4 via cultivation bed support frames 5, 5, 5, 5 so as to be relatively rotatable. For example, as shown in FIGS. 2 and 4, it is composed of two metal pipes 11, 11 that are supported in parallel at a predetermined interval. The cultivation bed support frames 5, 5, 5, 5 are constituted by, for example, a metal plate frame having a triangular shape in side view, and the central portions of the upper end side apex portions 5a, 5a, 5a, 5a are connected to connecting shafts 40, 40, 40. , 40, respectively, so as to be relatively rotatable on both left and right ends of each of the arm members 4, 4, while two arms are provided at a predetermined interval on the lower end side bottom portions 5b, 5b, 5b, 5b. Both ends of the metal pipes 11, 11, 11, 11 are engaged. Then, on the same two metal pipes 11, 11, 11, 11, two sets of peat bags 1, 1, 1, 1, which can manage the nutrient solution in the front and back directions, are installed respectively to serve as a culture medium (Fig. 5, (See Figure 6).

In Fig. 5, the middle part between the two pairs of front and rear peat bags 1 and 1 is cut out (see the two double-dashed lines), so they appear to be one pair, but the left and right ones are separate. Actually, two sets of peat bags 1 and 1 are installed. This also applies to the other frames 2, 2, . . . .

<Characteristics of the plant cultivation device according to the above embodiment>
According to the above configuration, the rotary shaft penetrating hole, which is the bearing hole of the bearing part 21, 21, on each of the plurality of frames 2, 2, etc., which are arranged in parallel at a predetermined interval in a predetermined direction. By rotating the rotating shaft 3 which is rotatably supported through the holes 30, 30..., a pair of front and rear arm members 4, 4, 4, 4... A pair of left and right cultivation beds, which are hung so that they can rotate relative to each other, are placed in a mutually horizontal first hanging state (Figures 1 and 2) and a mutually perpendicular second hanging condition (Figures 3 and 4) or vice versa.

Therefore, as in the case of the previous application already mentioned, if multiple rows of plant cultivation devices with the above configuration are installed adjacent to each other in the left and right direction in a predetermined plant cultivation facility, the pair of left and right cultivation beds are placed horizontally to each other. When maintained in the first suspended state (Figures 1 and 2), it is possible to effectively utilize the space within the cultivation facility and increase the number of planted plants (number of beds). Since each cultivation bed can be uniformly irradiated with sunlight, growth efficiency can be improved. On the other hand, when the pair of left and right cultivation beds are maintained in the second suspended state perpendicular to each other (FIGS. 3 and 4), a necessary working space is formed between the plural rows of plant cultivation devices in the left and right direction. be able to. Furthermore, by locating the cultivation bed that requires work on the upper side of the pair of left and right cultivation beds, it is possible to work in a comfortable working posture. Note that this second suspended state is not limited to a completely vertical state where the pair of cultivation beds are vertically located as shown in FIGS. 3 and 4, but also a vertical state that is inclined to some extent from the vertical state. It may be in a close state (vertical front state), and substantially the same purpose can be achieved. This also makes it possible to adjust the height of the cultivation bed located on the upper side.

Moreover, in the above-mentioned plant cultivation apparatus, a bearing part 21 is attached to the above-mentioned upper part, and the plurality of frames 2, 2, . A rotary shaft through hole position adjustment structure capable of arbitrarily adjusting the position of certain rotary shaft through holes 30, 30, etc. in the horizontal and vertical directions so that the rotary shaft 3 can linearly pass through the rotary shaft through holes 30, 30, etc. It is configured with.

Therefore, the positions of the rotation shaft penetration holes 30, 30, etc. of the respective bearing parts 21, 21, on the plurality of frames 2, 2, etc. that rotatably support the rotation shaft 3 are Using the rotating shaft penetration opening position adjustment structure of . As a result, even when the legs 24, 24, etc. (the second and third metal pipes 24b, 24b) of each mount 2, 2... are driven into the installation surface, multiple mounts 2, 2... The positions of the rotation shaft insertion holes 30, 30, etc. of the plurality of upper bearing parts 21, 21, etc. can be aligned on the same axis. Therefore, it is easy to insert the rotary shaft 3 into each of the rotary shaft insertion holes 30, 30, etc., and the supported rotary shaft 3 also rotates smoothly.

<About various modifications>
In the above description, a rectangular steel pipe with a square cross section, for example, is used as the rotating shaft 3, but this may be changed to, for example, a circular steel pipe or a solid circular shaft. In that case, an engaging portion that engages with each other is provided between the rotary shaft penetration hole of the arm members 4, 4 and the outer periphery of the rotary shaft 3, so that the arm members 4, 4 can be smoothly moved according to the rotation of the rotary shaft 3. Make it rotate.

Furthermore, in the above explanation, the leg portion 24 is formed by the first metal pipe 24a, the second metal pipe 24b, and the third metal pipe 24b each having a circular cross section. It can also be changed.

In addition, the length dimensions of the pair of front and rear arm members 4, 4, etc. and/or the vertical dimensions of the cultivation bed support frames 5, 5, etc. in the above explanation vary depending on the type of plants cultivated on the cultivation bed. Set to appropriate dimensions. For example, if the plant being cultivated is strawberries, the stalks will grow long and the fruit will hang down from both sides of the cultivation bed when the fruit is set.

Therefore, if the plants to be cultivated are strawberries or the like, the length of the arm members 4, 4, etc. should be made longer than in the case of other plants, and the length of the arm members 4, 4, etc. should be made longer than in the case of other plants. By shortening the vertical dimensions (dimensions between the upper end side top sides 5a, 5a... and the lower end side bottom sides 5b, 5b...), the rotation radius of the cultivation beds 5, 5... can be increased (the cultivation bed The distance between the bottom metal pipes 11, 11, etc. and the rotating shaft 3 is increased), and the arm member is changed from the state shown in FIG. 2 to the state shown in FIG. 4 (or vice versa, from the state shown in FIG. 4 to the state shown in FIG. 2). 4, 4... To prevent hanging strawberries from interfering with the rotating shaft 3 when the (cultivation bed) is rotated.

The present invention relates to a plant cultivation device in which a cultivation bed is rotatably supported on a predetermined pedestal via an arm member and a rotating shaft, and plants are cultivated using a space in a plant cultivation facility. be.

With recent plant cultivation equipment, it is important to increase the number of seedlings (number of beds) planted as much as possible in the limited space of a plant cultivation facility such as a greenhouse, and to increase the yield by giving plants on each cultivation bed equal sunlight at all times. There is a need to ensure uniform and good growth by applying light, and to be able to increase the number of seedlings planted as much as possible in a limited space while still being able to secure the necessary work space when needed.

Based on these circumstances, the inventors of the present application rotatably support a pair of left and right cultivation beds on a predetermined pedestal via an arm member and a rotating shaft in a plant cultivation facility such as the one described above. By rotating the rotation shaft using the rotation operation means, the pair of left and right cultivation beds are maintained both in a horizontal state in a first state and in a vertical state in which one is maintained upward and the other is downward. We have filed a patent application for a plant cultivation device that can be arbitrarily shifted to the state described in No. 2 (see Patent Document 1).

In a plant cultivation device having such a configuration, when the pair of left and right cultivation beds are maintained horizontally, the cultivation beds of the plurality of rows of cultivation devices are brought close to each other, thereby increasing the number of plants to be planted (number of beds). In addition, the cultivation bed of each cultivation device is evenly exposed to sunlight, achieving uniform and good growth conditions. Furthermore, when the pair of left and right cultivation beds are maintained vertically, a necessary working space is formed between the plurality of rows of cultivation devices. Therefore, each of the above demands can be met.

In the case of this plant cultivation device, the rotating shaft that rotatably supports the pair of left and right cultivation beds via the arm member is quite long (for example, about 25 m in total length), and the same A plurality of sets (for example, 4 sets) of frames are installed at a predetermined interval (for example, 6 m intervals) between both longitudinal ends of a long rotation shaft, and the long rotation is performed using a bearing provided at the center of the upper part of each frame. While the shaft is rotatably supported, a pair of front and rear arm members are provided between adjacent mounts, and a pair of left and right cultivation beds are provided between both ends of the front and rear pair of arm members, and are rotatably supported. Each of the multiple sets of frames has a gate-shaped structure, for example, with two legs on the left and right, and the two legs are placed on the installation surface in the cultivation facility with a foundation made of concrete, etc., and then leveled. It is installed at the required height by removing it.

As the long rotating shaft, a single unit (one piece) or a connected structure (additional structure) is arbitrarily adopted. At one end of this long rotating shaft, a manual rotation operation means equipped with, for example, a deceleration mechanism is provided. The arm member is rotated from a horizontal state to a vertical state and from a vertical state to a horizontal state.

As a result, the pair of left and right cultivation beds, which are suspended between both ends of the front and rear pair of arm members so as to be relatively rotatable, are also rotationally displaced from the horizontal state to the vertical state and from the vertical state to the horizontal state.

Patent No. 7034358

By the way, as in the plant cultivation apparatus of Patent Document 1, the rotation shaft is quite long, and a pair of front and rear arm members in multiple rows, a pair of front and rear arm members, is operated using a manual rotation operation means equipped with a deceleration mechanism. In order to smoothly rotate the rotating shaft that supports the pair of left and right cultivation beds supported between both ends of the arm member from one end to the other end without shaking, it is necessary to rotate the rotating shaft from one end to the other end smoothly. The entire structure must be supported in a straight, coaxial state by multiple bearings, that is, it must not be displaced in either the horizontal or vertical direction, and must be maintained as completely coaxial as possible. .

However, each frame in multiple rows has a gate-shaped structure with two legs on the left and right, and the connection part (bearing support part) that interconnects the two legs on the left and right and their upper ends is In the case of a completely fixed structure, the installation position and level adjustment must be performed for each of the multiple rows of frames as a whole, making the installation work extremely troublesome. Furthermore, pouring concrete foundations is itself a troublesome work, and there are also circumstances in which it is desirable to avoid pouring foundations in the field areas of plant cultivation facilities such as greenhouses as much as possible.

Therefore, for example, it may be possible to support the two legs of each multi-row mount at the required height by driving it into the soil of the installation surface (field site) to a predetermined depth, without needing to cast the foundation. . However, even in that case, if the connecting part (bearing support part) that interconnects the two left and right legs and their upper ends is a completely fixed structure, it is difficult to drive the legs, and there is no need for foundation work. and proper installation is difficult.

Under these circumstances, it has been found that there is still a need for improvement in the frame structure of the invention of the earlier application.

The present invention has been made in order to solve such problems, and includes a connecting member (bearing support part) that connects the two left and right legs that constitute the pedestal and the upper ends of the two left and right legs. By making the connecting parts relatively movable until the final fixed state, it can be used not only when performing foundation work, but also by simply driving the two left and right legs into the soil to a predetermined depth and supporting it at the required height. It is an object of the present invention to provide a plant cultivation device equipped with a mount that can easily adjust the position in both horizontal and vertical directions.

The present invention has the following configuration as a means for solving the above problems.

(1) Means for solving the problem of the invention of claim 1 The plant cultivation device of the invention of claim 1 includes a plurality of mounts arranged in parallel at a predetermined interval in a predetermined direction, and a plurality of mounts arranged on the upper part of the plurality of mounts. a plurality of bearing parts, a rotary shaft rotatably supported while penetrating each bearing hole of the plurality of bearing parts, and the rotary shaft between mutually opposing bearing parts of the plurality of bearing parts. Each arm member is located on the end side of each bearing and is supported in the middle part in an orthogonal state, and rotates in the vertical direction according to the rotation of the rotation axis, and both ends of each arm member are rotatable relative to each other. and a pair of cultivation beds suspended from each other, and by rotating the rotation shaft with a predetermined rotation means, the pair of cultivation beds suspended from both ends of each of the arm members in a relatively rotatable manner. A plant cultivation device that displaces a mutually horizontal first hanging state and a mutually perpendicular or nearly vertical second hanging state, wherein the plurality of mounts each have a position of a bearing hole of the bearing part. The rotating shaft is configured to include a bearing hole position adjustment structure that can be arbitrarily adjusted in the horizontal and vertical directions so that the rotating shaft can linearly pass through the rotating shaft in a coaxial state , and each of the bearing parts It is attached to each frame so as to be tiltable in the front and rear directions, and the opening surface of the bearing hole is adjustable along the vertical direction .

According to such a configuration, a rotating shaft that is rotatably supported by penetrating the bearing hole of the bearing section on each of the multiple mounts installed in parallel at a predetermined interval in a predetermined direction is rotated. By doing so, the pair of left and right cultivation beds, which are hung so as to be relatively rotatable at both ends of the pair of front and rear arm members between each mount, can be changed from a mutually horizontal first suspended state to a mutually vertical or nearly vertical suspended state. It can be arbitrarily displaced into the second suspended state or vice versa.

Therefore, as in the case of the previous application, when a plurality of rows of plant cultivation devices having the above configuration are installed adjacent to each other in the left and right direction in a predetermined plant cultivation facility, the pair of left and right cultivation beds are placed in the horizontal first By maintaining the hanging condition, it is possible to effectively utilize the space within the cultivation facility and increase the number of planted plants (number of beds).In addition, each of the pairs of left and right cultivation beds can be uniformly exposed to sunlight. can be irradiated, so growth efficiency can be improved. On the other hand, when the pair of left and right cultivation beds are maintained in a second hanging state that is perpendicular or nearly perpendicular to each other, a necessary working space can be formed between the plurality of rows of plant cultivation devices in the left and right direction. Furthermore, by locating the cultivation bed that requires work on the upper side of the pair of left and right cultivation beds, it is possible to work in a comfortable working posture. This second suspended state may be shifted to a completely vertical state in which the pair of cultivation beds are vertically located, but it is also possible to shift the pair of cultivation beds to a completely vertical state in which they are located vertically, or to a near-vertical state where the cultivation beds are tilted to some extent from the same vertical state (a state in front of the vertical). ), and can achieve almost the same purpose. This also allows the height of the cultivation bed located on the upper side to be adjusted.

In the plant cultivation device of the present invention, in the structure of the plant cultivation device, a bearing portion is attached to the upper portion, and each of the plurality of frames supporting the rotating shaft via the bearing portion is connected to the bearing portion of the bearing portion. A bearing hole position adjustment structure is provided that can arbitrarily adjust the position of the hole in the horizontal and vertical directions so that the rotating shaft can linearly pass through the bearing hole in a coaxial state.

Therefore, the positions of the bearing holes of the respective bearings on the plurality of frames that rotatably support the rotating shafts are adjusted so that the rotating shafts are aligned in a straight line using the bearing hole position adjustment structure of the frames. Suitably adjusted horizontally and vertically to allow penetration. As a result, even when the legs of each pedestal are driven into the installation surface, the positions of the bearing holes of the plurality of bearing parts on the plurality of pedestals can be aligned on the same axis. Therefore, it is easy to insert the rotating shaft into each bearing hole, and the supported rotating shaft also rotates smoothly.

In this case, the plurality of bearings are attached to the respective corresponding frames so as to be tiltable in the front and rear directions, and the opening surfaces of the bearing holes can be adjusted so as to be along the vertical direction. It is characterized by

According to such a configuration, not only can the positions (center positions) of the bearing holes of the plurality of bearing parts on the plurality of frames be aligned on the same axis, but also the positions (center positions) of the bearing holes of the plurality of bearing parts on the plurality of frames can be aligned. Since the opening surface of each bearing hole can be adjusted along the vertical direction, it is possible to ensure that the opening surface of each bearing hole is perpendicular to the rotation axis extending in the horizontal direction. As a result, the center axes of the bearing holes of the respective bearing portions more reliably match with each other, making it possible to support the rotating shaft in a mutually concentric state. Therefore, the rotating state of the rotating shaft also becomes smoother.

(2) Means for solving the problem of the invention according to claim 2 The plant cultivation apparatus according to the invention according to claim 2 is the plant cultivation apparatus according to the invention according to claim 1, in which the plurality of bearing parts are arranged in front and rear relative to each corresponding mount.

It is characterized by consisting of a roller member, a circular rotating plate that is rotatably held while being inscribed inside the plurality of roller members, and a bearing hole provided in the center of the rotating plate. There is.

As shown in the configuration of the plant cultivation device of the invention of claim 1 , the plurality of bearings provided at the center of each of the plurality of mounts can be tilted (raised and lowered) in the front and rear directions with respect to each mount. It is preferable that the opening surface of the bearing hole is adjustable along the vertical direction. By doing so, it is possible to ensure that the opening surface of each bearing hole is perpendicular to the rotating shaft extending in the horizontal direction, and the center axes of the bearing holes of each bearing part are more reliably aligned. This allows the rotating shafts to be supported in a mutually concentric state. Therefore, the rotating state of the rotating shaft also becomes smoother.

In the case of such a configuration, each bearing part includes a bearing body plate having a semicircular upper part and a rectangular lower part, which is attached to be tiltable in the front-rear direction with respect to each corresponding mount; A ring plate that coaxially corresponds to the upper semicircular portion of the bearing body plate and is connected and integrated at a predetermined interval via a plurality of connecting shafts provided on the outer periphery, and the ring plate and A plurality of roller members are rotatably fitted loosely around the outer periphery of the plurality of connection shafts that connect the upper portions of the bearing body plates, and the roller member is rotatably held in a state inscribed inside the plurality of roller members. When the rotary plate is composed of a circular rotating plate and a bearing hole provided in the center of the rotating plate, the rotating shaft is supported by the bearing hole of the rotating plate with a thin thickness in the direction of the rotating axis, Even if the penetrating portion of each bearing hole has a certain degree of inclination in the front-rear direction, the influence thereof is small, and smoother rotation of the rotating shaft can be maintained.

(3) Means for solving the problem of the invention according to claim 3 The plant cultivation apparatus according to the invention according to claim 3 is the plant cultivation apparatus according to the invention according to claim 2 , in which the rotating shaft is made of a square steel pipe member, and the bearings of each rotating plate are The hole is characterized in that it is a rectangular rotating shaft through-hole into which a rotating shaft made of a coaxial steel pipe member is inserted in a coaxial horizontal state .

In this manner, in the configuration of the bearing portion of the invention of claim 2, the rotating shaft is formed of a rectangular steel pipe member, and each rotating shaft is rotatably held in a state inscribed inside a plurality of roller members. If the bearing hole of the plate is formed into a rectangular rotation shaft penetration hole into which a rotation shaft made of a coaxial steel pipe member is inserted in a coaxial horizontal state, the rotation shaft made of a rectangular steel pipe member can be inserted into the rotation shaft of each rotation plate. By simply inserting the rotary shaft into the shaft insertion hole, the rotary shaft and each rotary plate are easily engaged with each other, and are reliably rotatably supported by the plurality of roller members via each rotary plate.

As a result of the above, in the plant cultivation device of the present invention, it is easy to adjust the level of each of the plurality of frames arranged in a predetermined direction at a predetermined interval, and the bearing hole of the bearing part of each of these frames can be adjusted easily. Even when a long rotating shaft penetrates and is rotatably supported, it can be reliably supported in a concentric state. Therefore, the rotation of the pair of left and right cultivation beds suspended via the pair of front and rear arm members and the pair of front and rear arm members becomes smooth, and the rotation operation by the one end side rotation operation means is also facilitated.

That is, in the case of this embodiment, as described above, on the leg portion 24 side, the second and third metal pipes 24b, 24b, 24b, 24b, etc., which are a pair of left and right supports, are first stretched with strings. etc., and install it as vertically as possible with a predetermined left-right width and a predetermined front-to-back spacing (drive-in installation). Then, the first metal pipes 24, 24, etc. that support the bearing part 21 are connected to the second and third metal pipes 24b, 24b, 24b, 24b, etc., which are the pair of left and right supports. By engaging and fixing the first metal pipe 24a using the bracket members 27, 27, it is possible to adjust the vertical height (ground clearance) and lateral position (horizontal engagement position) of the first metal pipe 24a. Therefore, the state in which the first metal pipes 24, 24, etc. are supported by the legs 24, 24, etc. of the plurality of frames 2, 2, etc., which are arranged in series at predetermined intervals in the front-rear direction, is different from that of the first metal pipes, respectively. The pipes 24a, 24a are set at a common height and lateral position as a whole.

However, even if the first metal pipes 24, 24, . . . as bearing support members are at the same height and horizontal position as a whole, the first metal pipes 24a, 24a, . * are separate pieces, and the second and third metal pipes 24b, 24b, 24b, 24b, etc. are not necessarily driven in an accurate vertical state. Therefore, in order to attach the bearing portions 21, 21, etc. to the intermediate portions in the left-right direction of each of the first metal pipes 24a, 24a, etc. via the bearing mounting members 22, 22, etc. in an accurate vertical state, the first It is also necessary to adjust the vertical position of the bearing parts 21, 21, etc. in relation to the metal pipes 24a, 24a, .

As described above, the bearing mounting member 23 that supports the bearing part 21 in the vertical direction is connected and fixed to the first metal pipe 24a of the leg part 24 of the pedestal 2 via the U-shaped rods 26, 26. Then, such requests can be reliably met.

<About the support structure of the rotating shaft 3 by the bearing part 21>
In this embodiment, the elongated rotating shaft 3 is, for example, a rectangular steel pipe member with a square cross section. The rotating shaft 3 made of the rectangular steel pipe member is inserted into the rotating shaft penetrating hole ( (corresponding to the bearing holes in the claims) 30, 30, etc., in a coaxial horizontal state and rotatably supported. In this case, the shape of the rotating shaft insertion holes 30, 30, etc. in each of the rotating plates 21c, 21c, etc. naturally corresponds to the external shape of the rotating shaft 3, but the inner diameter dimension is As an example, it is formed to have a larger dimension with a predetermined gap relative to the outer diameter dimension of the rotating shaft 3. A predetermined gap is sufficient for engagement in the rotational direction between the rectangular rotating shaft 3 and the rectangular rotating shaft penetration holes 30, 30, etc., and the rotation of the rotating shaft 3 in this embodiment is Since the rotation is temporary and slow, there is no risk of generating noise during rotation even if there is a predetermined gap between the mutually inserted portions.

In particular, in this embodiment, a continuous long rotating shaft 3 is supported between the bearing parts 21, 21, etc. of a plurality of frames 2, 2, etc., which are located at a considerable distance (25 m) in the front and rear direction. Therefore, if there is a horizontal or vertical positional shift in the rotating shaft insertion holes 30, 30, which are bearing holes, it will be difficult to insert the long rotating shaft 3 straight through, and it will be difficult to insert the long rotating shaft 3 straight through. Even if it is inserted, there is a possibility that a cross-direction force will be generated between the rotary shaft insertion holes 30, 30, and the rotary shaft 3, and the rotary shaft 3 will not rotate smoothly.

However, as described above, the rotating shaft through holes 30, 30, etc. in the bearing portion 21 are formed in the rotating plate 21c, which is thin in the axial direction of the rotating shaft 3, and the rotating shaft through holes 30, 30... By making the inner diameter of ... a predetermined dimension larger than the outer diameter of the rotating shaft 3, not only will it be easier to insert the rotating shaft 3, but there will also be a small amount of space in the rotating shaft penetration holes 30, 30..., which are bearing holes. Even if there is a positional shift in the horizontal or vertical direction, no cross-direction force is generated between the rotating shaft 3 and the rotating shaft 3, and smooth rotation can be achieved. Further, in the case of this embodiment, not only the rotating plate 21c in which the rotating shaft penetration holes 30, 30, . . . Both the ring plate 21a and the ring plate 21a are formed of flat plate members. Therefore, it becomes easier to realize the above effect.

Further, the undulation angle of the bearing portion 21, which is flat as a whole and small in dimension in the direction of the rotating shaft 3, is adjustable as described above. Therefore, in the case of the same configuration, even if the length of the rotating shaft 3 becomes considerably long, easy insertion and smooth rotation can be realized.

<Configuration of arm members 4, 4>
The arm members 4, 4 provided at both front and rear end sides between the mutually opposing mounts 2, 2 of the plurality of mounts 2, 2, etc. are shown, for example, in FIGS. 2 and 4 to 6. As shown in FIG. (not shown). By inserting the rotary shaft 3 into the rotary shaft penetration hole, the rotary shaft 3 is supported in the space above the mounts 2, 2, and the vertical surface around the rotary shaft 3 changes according to the rotation of the rotary shaft 3. It can be rotated clockwise or counterclockwise along.

<Configuration of a pair of left and right cultivation beds>
On the other hand, in the case of this embodiment, a pair of left and right cultivation beds are suspended from the right and left ends of each of the arm members 4, 4 via cultivation bed support frames 5, 5, 5, 5 so as to be relatively rotatable. For example, as shown in FIGS. 2 and 4, it is composed of two metal pipes 11, 11 that are supported in parallel at a predetermined interval. The cultivation bed support frames 5, 5, 5, 5 are constituted by, for example, a metal plate frame having a triangular shape in side view, and the central portions of the upper end side apex portions 5a, 5a, 5a, 5a are connected to connecting shafts 40, 40, 40. , 40, respectively, so as to be relatively rotatable on both left and right ends of each of the arm members 4, 4, while two arms are provided at a predetermined interval on the lower end side bottom portions 5b, 5b, 5b, 5b. Both ends of the metal pipes 11, 11, 11, 11 are engaged. Then, on the same two metal pipes 11, 11, 11, 11, two sets of peat bags 1, 1, 1, 1, which can manage the nutrient solution in the front and back directions, are installed respectively to serve as a culture medium (Fig. 5, (See Figure 6).

In Fig. 5, the middle part between the two pairs of front and rear peat bags 1 and 1 is cut out (see the two double-dashed lines), so they appear to be one pair, but the left and right ones are separate. Actually, two sets of peat bags 1 and 1 are installed. This also applies to the other frames 2, 2, . . . .

<Characteristics of the plant cultivation device according to the above embodiment>
According to the above configuration, the rotary shaft penetrating hole, which is the bearing hole of the bearing part 21, 21, on each of the plurality of frames 2, 2, etc., which are arranged in parallel at a predetermined interval in a predetermined direction. By rotating the rotating shaft 3 which is rotatably supported through the holes 30, 30..., a pair of front and rear arm members 4, 4, 4, 4... A pair of left and right cultivation beds, which are hung so that they can rotate relative to each other, are placed in a mutually horizontal first hanging state (Figures 1 and 2) and a mutually perpendicular second hanging condition (Figures 3 and 4) or vice versa.

Therefore, as in the case of the previous application already mentioned, if multiple rows of plant cultivation devices with the above configuration are installed adjacent to each other in the left and right direction in a predetermined plant cultivation facility, the pair of left and right cultivation beds are placed horizontally to each other. When maintained in the first suspended state (Figures 1 and 2), it is possible to effectively utilize the space within the cultivation facility and increase the number of planted plants (number of beds). Since each cultivation bed can be uniformly irradiated with sunlight, growth efficiency can be improved. On the other hand, when the pair of left and right cultivation beds are maintained in the second suspended state perpendicular to each other (FIGS. 3 and 4), a necessary working space is formed between the plural rows of plant cultivation devices in the left and right direction. be able to. Furthermore, by locating the cultivation bed that requires work on the upper side of the pair of left and right cultivation beds, it is possible to work in a comfortable working posture. Note that this second suspended state is not limited to a completely vertical state where the pair of cultivation beds are vertically located as shown in FIGS. 3 and 4, but also a vertical state that is inclined to some extent from the vertical state. It may be in a close state (vertical front state), and substantially the same purpose can be achieved. This also makes it possible to adjust the height of the cultivation bed located on the upper side.

Moreover, in the above-mentioned plant cultivation apparatus, a bearing part 21 is attached to the above-mentioned upper part, and the plurality of frames 2, 2, . A rotary shaft through hole position adjustment structure capable of arbitrarily adjusting the position of certain rotary shaft through holes 30, 30, etc. in the horizontal and vertical directions so that the rotary shaft 3 can linearly pass through the rotary shaft through holes 30, 30, etc. It is configured with.

Therefore, the positions of the rotation shaft penetration holes 30, 30, etc. of the respective bearing parts 21, 21, on the plurality of frames 2, 2, etc. that rotatably support the rotation shaft 3 are Using the rotating shaft penetration opening position adjustment structure of . As a result, even when the legs 24, 24, etc. (the second and third metal pipes 24b, 24b) of each mount 2, 2... are driven into the installation surface, multiple mounts 2, 2... The positions of the rotation shaft insertion holes 30, 30, etc. of the plurality of upper bearing parts 21, 21, etc. can be aligned on the same axis. Therefore, it is easy to insert the rotary shaft 3 into each of the rotary shaft insertion holes 30, 30, etc., and the supported rotary shaft 3 also rotates smoothly.

<About various modifications>
In the above description, a rectangular steel pipe with a square cross section, for example, is used as the rotating shaft 3, but this may be changed to, for example, a circular steel pipe or a solid circular shaft. In that case, an engaging portion that engages with each other is provided between the rotary shaft penetration hole of the arm members 4, 4 and the outer periphery of the rotary shaft 3, so that the arm members 4, 4 can be smoothly moved according to the rotation of the rotary shaft 3. Make it rotate.

Furthermore, in the above explanation, the leg portion 24 is formed by the first metal pipe 24a, the second metal pipe 24b, and the third metal pipe 24b each having a circular cross section. It can also be changed.

In addition, the length dimensions of the pair of front and rear arm members 4, 4, etc. and/or the vertical dimensions of the cultivation bed support frames 5, 5, etc. in the above explanation vary depending on the type of plants cultivated on the cultivation bed. Set to appropriate dimensions. For example, if the plant being cultivated is strawberries, the stalks will grow long and the fruit will hang down from both sides of the cultivation bed when the fruit is set.

Therefore, if the plants to be cultivated are strawberries or the like, the length of the arm members 4, 4, etc. should be made longer than in the case of other plants, and the length of the arm members 4, 4, etc. should be made longer than in the case of other plants. By shortening the vertical dimensions (dimensions between the upper end side top sides 5a, 5a... and the lower end side bottom sides 5b, 5b...), the rotation radius of the cultivation beds 5, 5... can be increased (the cultivation bed The distance between the bottom metal pipes 11, 11, etc. and the rotating shaft 3 is increased), and the arm member is changed from the state shown in FIG. 2 to the state shown in FIG. 4 (or vice versa, from the state shown in FIG. 4 to the state shown in FIG. 2). 4, 4... To prevent hanging strawberries from interfering with the rotating shaft 3 when the (cultivation bed) is rotated.
