[Detailed description of the invention] (Industrial application field) The present invention relates to a multi-stage mobile rotary cultivation device for growing plants and the like.

(Technical background) In the facility cultivation of plants, mushrooms, etc., nutrients, air (oxygen), light, temperature, humidity, etc. are required to provide each cultivated plant with ideal growth conditions in a limited space. is controlled to provide the ideal supply.

For this purpose, it is necessary to accurately control the entire process to prevent unevenness as much as possible.

However, the conventional mobile rotary cultivation apparatus has the following problems.

In other words, unevenness in nutrient supply, unevenness in air circulation, unevenness in air supply to inner plants especially in densely planted cultivated plants, deformation of plant morphology due to unevenness in the amount and direction of light reception, temperature,
There is uneven growth due to uneven humidity, especially indoor temperature differences.

Therefore, the present invention is intended to solve these problems, and is a multi-stage cultivation unit with a movable and rotatable cultivation unit that can significantly improve air circulation and reduce other unevenness at the same time. A mobile rotary cultivation device is provided.

(Means for Solving the Problems) In order to solve the above problems, the multi-stage mobile rotary cultivation apparatus according to the present invention includes the following i configurations.

In other words, cultivation pallets are stacked at three-dimensional intervals, the stacked cultivation pallets are integrated, and a large number of these integrated cultivation units are moved and rotated indoors based on certain rules, and the stacked cultivation In order to improve air convection between the pallets in the vertical direction, the cultivation pallets are provided with air circulation parts that open in the vertical direction.

(effect) Let's talk about the action.

The cultivation unit with multi-tiered cultivation pallets is movable and rotatable, allowing for even photosynthesis, air supply and distribution, and the air circulation section ensures even air circulation even when plants are densely planted on the plant cultivation bed. sufficient and of good quality
It is possible to produce large quantities of fL products.

(Example) Preferred examples embodying the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a cultivation unit 12 formed by stacking cultivation pallets 10 at intervals in the vertical direction. In other words, cultivation units are formed not only by utilizing space in a two-dimensional manner, but also by stacking them three-dimensionally from bottom to top.

In the figure, a moving device such as a trolley is provided at the ceiling portion 14 at the upper end, and a large number of each cultivation unit 12 is driven in circulation by an endless chain or the like.

FIG. 2 is a plan view of the cultivation chamber showing the circulation state of the cultivation unit 12. 38 is a work room, 11 is a guide rail, and the cultivation unit 12 is suspended from this guide rail 11.

That is, a connected rotary shaft 16 is provided rotatably via a support shaft 13 hanging from an endless chain disposed within the guide rail 11, and this connected rotary shaft 1
6 supports five cultivation pallets 10 at regular intervals, and each cultivation pallet 10 is fixed to a connecting rotation shaft 16 by appropriate fixing means.

The cultivation pallet 10 has two ring-shaped and groove-shaped cultivation beds 24a and 24b arranged concentrically. A through hole 10a is formed in the area surrounded by the inner cultivation bed 24a, through which the connecting rotation shaft 16 passes, and an opening part 10b, which is an air circulation part that is open vertically, is formed between the inner and outer cultivation beds 24a and 24b. It is formed. This opening portion 10b allows smooth air circulation in the vertical direction of the cultivation unit 12. In addition, two cultivation beds 24a
, 24b are communicated with each other by a communication pipe 24c.

A nutrient solution supply pipe 20 for supplying nutrient solution to each cultivation pallet 10 is arranged along the connecting rotation shaft 16, so that excess nutrient solution flows down from the cultivation pallet 10 to the cultivation pallet 10 below. A drain pipe 22 is provided.

Further, the cultivation pallet 10 can take various shapes, such as the above-mentioned disk shape or polygonal plate shape, as long as it does not collide with other cultivation units during rotation.

Furthermore, if it is a problem that the inner peripheral part of the cultivation pallet 10 obstructs air circulation in the vertical direction, the connecting rotation shaft 16 is not passed through the central through-hole 10a of the cultivation pallet 10, and this part is transparent. It is also possible to leave the holes 10a as they are and support the outer periphery of the cultivation pallet 10 with a plurality of shafts 25 (see FIG. 3).

In addition, the openings of the cultivation pallet may have a mesh shape, a spoke shape, or a fixed fan shape.

In particular, in the case of a fan-shaped cultivation unit, air is forced upward or downward every time the cultivation unit is rotated, resulting in uneven (convection) and smooth air supply.

In addition, the cultivation bed 24a inside the cultivation pallet 10 is suitable for cultivating low-light plants that do not require much light (seedlings, young seedlings, etc.). Once the seeds have grown, the space can be used effectively by repeatedly transplanting them to the outer cultivation bed 24b. This is possible because young seedlings have a very small height and do not obstruct air circulation.

A bar 26 is provided to protrude from the lower end of the connecting rotation shaft 16, and the bar 26 is inserted into a bar guide 28 for guiding the cultivation unit. A nutrient solution inlet 3 is provided at the top of the connected rotating shaft 16.
0 is assigned.

Reference numeral 34 denotes an L-shaped hook that projects horizontally from the upper end of the connecting rotation shaft 16 in the left-right direction.The cultivation unit 12 is moved by a rotation guiding bar 36 that projects and hangs from the ceiling and is used to apply rotational force to the cultivation unit 12 when it comes into contact with the hook. Sometimes given a couple for rotation. By doing so, there is no need to provide a rotary motor or the like to each of the many cultivation units, and the cost, weight, complexity, etc. of the entire device can be reduced. The rotation guide bar 36 is not only provided on one side of the cultivation unit 12, for example, on the right side in the direction of movement, but is also provided alternately on the left and right sides, thereby preventing wind from always blowing from one direction due to rotation, and improving the growth of plants. can also be made uniform. Further, a gear can be used instead of the L-shaped hook 34, and a rack can be used instead of the rotation guide bar 36 to apply rotational force. In short, the force couple of the rotation system that applies a couple force to the shaft or the like when moving the unit to rotate it can be determined as the moving force of the unit itself.

Moreover, 32 is a nutrient solution supply pipe, and the nutrient solution supply pipe 32 is provided at an appropriate position on the path of the moving cultivation unit 12, for example, at a bending portion where the guide rail 11 is bent into a hairpin shape. During the circulation movement of the cultivation unit 12, the nutrient solution is supplied to the nutrient solution inlet 30 at the bent portion of the guide rail 11 (that is, the nutrient solution is intermittently supplied to the cultivation unit 12). ). Further, the tip of the L-shaped hook 34 of the cultivation unit 10 hits the nutrient solution supply pipe 32 to define the nutrient solution supply position.

Although the cultivation unit 12 can be placed upright on the floor, it is easiest to move it while hanging from the ceiling, and it is preferable that the movement is in an endless loop. In addition, as shown in FIG. 2, the direction of movement of the cultivation unit 12 is such that after going around the three outer circumferences of the room that is provided to absorb sunlight, a route connecting the routes covers the plane. A combination of a U-shape and a meandering shape is suitable, and the workroom 38 may be temporarily reached in a part of the route.

Harvesting, planting, chemical spraying, nutrient solution injection, etc. can be concentrated in the work room 38.

By using a cultivation pallet having a ring-shaped planting section, crops can be planted efficiently and the pallet and crops can be prevented from colliding with each other even when the unit is rotated. Especially when planted in a ring shape on the outer periphery,
The light hits the plants evenly and without waste, and even when the distance between the crops is narrowed to the maximum, there is enough space inside and outside the crops to allow them to spread in that direction, making dense planting possible. Also, since there is a space inside, air circulation is not impaired.

In this way, when using the cultivation device according to the present invention, it is possible to employ indoor air equalization means such as providing an air circulation section in the center of the cultivation pallet to improve air circulation and then rotating the unit to move it around the room. This eliminates unevenness caused by the formation of air passages and unevenness in light irradiation, making it possible to control uniform growth of the entire device, and combined with the increase in yield due to the multistage system, it has a revolutionary effect.

Furthermore, by placing plants that require a large amount of heat and light in an upper cultivation device, it is possible to cross-plant various plants and compensate for each other, thereby preventing virus infection. .

(Effects of the Invention) As described above, according to the present invention, the cultivation pallet is provided with an air circulation section, and the cultivation unit is made movable and rotatable, so that air circulation is smooth, which eliminates the drawbacks of conventional dense cultivation. This eliminates poor growth caused by overlapping leaves of plants, stuffiness caused by heat and humidity, and poor ventilation. .

Furthermore, although the cultivation equipment is installed in multiple tiers, photosynthesis can be carried out sufficiently in both the upper and lower tiers, and there are remarkable effects such as no hindrance to cutting.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
