Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cultivation device for plants, etc., which has a plurality of rotary cultivation benches on a rotating frame.

[Prior Art] In order to effectively utilize land, a three-dimensional rotary type plant cultivation apparatus shown in FIGS. 6 and 7 has been proposed. Rotary cultivation benches are provided at several locations on the circumference of the rotating frame a. The rotary cultivation bench has a rotary member c rotatably attached to a rotary frame a and having arms b extending in three directions from a central portion thereof. A cultivation bench d is suspended from arm b via a pin. The rotating frame a is provided with a switching device g mainly composed of a guide e and a switching valve f in order to rotate the rotating member c by 1/3 for each rotation.

[Problems to be solved by the invention] However, in the cultivation device described above, the rotating direction of the rotating frame a is limited to only one direction and reverse rotation is not possible. Furthermore, it is necessary to provide each arm b with a roller h that rolls on a guide e, which increases the number of parts and increases costs. Furthermore, the collision of the changing device g when changing the cultivation bench causes large shaking of the cultivation bench d.

The present invention was devised to solve the above-mentioned problems of the conventional technology, and the purpose of the present invention is to provide a rotating frame that can be rotated forward and backward, and a rotary cultivation bench that is continuously and smoothly rotated. An object of the present invention is to provide a device for cultivating plants, etc., which has a simple structure.

[Means for Solving the Problems] The present invention includes a rotating frame that is rotatably supported on a pedestal frame so as to be rotatable in forward and reverse directions, and a plurality of rotatable frames provided at appropriate intervals along the circumferential direction of the rotating frame. A cultivation device for plants, etc., comprising a rotating member, a plurality of cultivation benches that are swingably suspended along the circumferential direction of the rotating member, and a drive device that rotationally drives the rotating frame, , a sprocket is provided fixed to be coaxial with the central axis of the rotating frame, and a sprocket for rotating the rotating member is provided on the central axis of each of the rotating members, and the sprockets of each rotating member are interlocked with each other. In order to rotate, the sprockets of each rotating member are spanned by an endless chain along the circumferential direction of the rotating frame, and a part of the chain is extended to the side of the sprocket fixed to the pedestal. It is made by rolling it around.

[Operation] When the rotating frame is rotationally driven by a drive device or the like, the chain moves on a sprocket fixed to a frame or the like at the center of the rotating frame, and the rotating member connected to the sprocket of the rotating member rotates. The rotation of this rotating member changes the positions of the plurality of trial benches suspended thereon, thereby making the solar radiation conditions of each cultivation bench uniform.

[Examples] Examples of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, 1 is a rotating frame. The rotating frame 1 is held by a central shaft 2 disposed in the longitudinal direction of the cultivation device, spokes 3 extending radially from both ends of the central shaft 2 (only one end is shown in the drawing), and the spokes 3. Ring body 4
It is mainly composed of. An end of the central shaft 2 is rotatably supported by a pedestal 6 via a bearing 5.

Rotating members 7 are provided on the ring body 4 at regular intervals along its circumferential direction. The rotating member 7 is shown in FIG.
As shown in an enlarged view in FIG. 5, it has an arm 9 extending in three directions from a central portion connected to a shaft 8 rotatably attached in the axial direction of the annular body 4. The angle between arms 9, 9 is 120°. A beam 10 is spanned between the tips of the arms 9 of the rotating member 7, which are provided at opposite ends of the central axis 2 to face each other. 1 cultivation bench for each beam 10
1 is hung swingably.

A sprocket 12 is attached to the center shaft 2 near the bearing 5, which is fixed to the frame and does not rotate itself. A sprocket 13 is also attached to the shaft 8 of each rotating member 7. Each sprocket 13 of these rotating members 7 has an endless chain 1 along the circumferential direction of the rotating frame 1.
4 is stretched around in a loop shape, and a part of this chain 14 is further wound around a sprocket 12 fixed to a frame 6, so that a part of a circle is cut out into a fan shape. The pedestal 6 is provided with a drive device 15 having a drive roller in close contact with the annular body 4 of the rotating frame 1 to rotate the ring body 4 .

When the rotating frame 1 is rotated by the drive device 15, the sprocket 1 fixed to the mount side at the end of the central shaft 2 of the rotating frame 1 is rotated as the rotating frame 1 rotates.
The chain 14 wound around the sprocket 12 moves on the circumference of the sprocket 12. Thereby, the chain 14 moves on the circumference between the sprockets 13 of each rotating member 7. The sprocket 13 rotates in accordance with this amount of movement, and the position of the cultivation bench 11 suspended from each arm 9 of the rotating member 7 changes. Third
The figure shows the situation when the ratio of the number of teeth between the sprocket 12 of the central shaft 2 and the sprocket 13 of the rotating member 7 is set to 1/3. In this case, rotating frame 1 is 1
With each rotation, the rotating member 7 rotates by 4/3. That is, the rotating member 7 rotates 4/3 times each time it revolves once around the central axis 2, and the rotating frame 7
The cultivation bench 10 returns to its original position with three rotations as one cycle. In addition, in FIG. 3, the inside of the cutout is the state after one round. When the rotating member 7 rotates in this way and the trial bench 11 of each arm 9 comes to the upper part of the rotating frame 1 where it is easily exposed to sunlight, the cultivation bench 11 is placed in the upper position of the rotating frame 1 in order. Since they are replaced, the three cultivation benches 11 of each rotating member 7 have uniform solar radiation conditions. Therefore, crops of uniform quality can be harvested on the three cultivation benches 11.

In addition, in the above embodiment, the sprocket 12,
By changing the number of teeth 13, the ratio of the teeth, the way the chain 14 is connected, etc., the speed and direction of rotation of the rotating member 7 relative to the rotation of the rotating frame 1 can be changed.

[Effects of the invention] In summary, the invention provides the following effects.

(1) The rotating direction of the rotating frame can be changed between forward and reverse. Therefore, when installing the present cultivation device in a greenhouse, workability is good regardless of the arrangement in the greenhouse.

(2) Since the rotation system uses a chain and sprocket, the number of parts can be reduced and costs can be reduced compared to the conventional rotation system that uses rollers.

(3) Simply by changing the number of teeth on the sprocket on the central shaft, the rotational speed of the rotating member can be easily changed as desired. Furthermore, by changing the way the chain is hung, the direction of rotation of the rotating member can also be changed.

(4) Since the rotating member rotates continuously and smoothly as the rotating frame rotates, the shaking of the cultivation bench is reduced, and the load fluctuation of the rotating frame drive device is also reduced, resulting in an energy-saving design.
