Description

Root cutting mechanism, plant cultivation device, and hydroponic cultivation device

The present invention relates to an apparatus for artificially cultivating a plant, and a root cutting mechanism for cutting roots of the cultivated plant.

In recent years, techniques for artificially growing plants in plant factories have been developed. At present, most plants grown in plant factories are leafy vegetables. Such leaf vegetable plants are often discarded without using their roots and harvesting their leaves and fruits. It is expected that varieties that can be cultivated in plant factories will be expanded in the future.

Here, in plant factories, cost efficiency is the biggest issue, so crops with few residues (those that can use all roots, etc.) are required as plants to be cultivated.

As an example, garlic is generally often harvested as edible bulbs, but the stems and leaves are also used as vegetables.

In particular, garlic is rich in ajoene, which is said to be applicable to various medical uses in the root part. Thus, garlic is a crop with little residue.

Patent Document 1 proposes a cultivation method for efficiently cultivating garlic roots using a hydroponic cultivation system.

Also, Patent Document 2 proposes a root cutting device for harvesting plant roots. In Patent Document 2, a net frame having a mesh through which a germinated plant can pass, and an upper or lower surface of the net frame, or a root that cuts a portion below the net when a cutter passes between a plurality of net frames. An apparatus is disclosed.

Roots of plants such as garlic are regenerated even if they are cut once. For this reason, in order to efficiently harvest plant roots in hydroponics, an apparatus that repeatedly harvests plant root portions is required.

The hydroponics system described in Patent Document 1 is not provided with a configuration for harvesting garlic roots that are hydroponically cultivated. For this reason, in the hydroponic cultivation system described in Patent Document 1, when harvesting garlic roots, it is necessary to remove the garlic that is hydroponically cultivated from the hydroponic cultivation system and then harvest the garlic roots. There is. Thus, the hydroponic cultivation system described in Patent Document 1 has a problem that the efficiency for harvesting roots is poor.

Also, the rooting device described in Patent Document 2 does not assume the use of roots, and does not consider a cultivation method that continues cultivation after root cutting. For this reason, since the root cutting apparatus described in Patent Document 2 cuts off all the roots of the plant body, it causes a great damage to the growth of the plant after the root cutting.

The present invention has been made to solve the above-mentioned problems, and its purpose is to suppress the influence on the growth of the plant cultivated by the plant cultivation apparatus and to efficiently harvest the root of the plant. To do.

In order to solve the above-mentioned problems, the root cutting mechanism of the present invention can be attached to a plant cultivation apparatus for cultivating a plant, and is a root cutting mechanism for cutting the root of the plant, which supports the plant. A movable part arranged to be able to be pressed on the support base, and a cutout which is arranged at the tip of the movable part and cuts off the root of the plant leaving a part by pressing the movable part It is characterized by having a part.

According to the above configuration, the movable part having the cutting part at the tip is arranged on the support base so that it can be pressed. Thereby, the root of the plant which a support stand supports can be cut out by pushing down the above-mentioned movable part.

For this reason, in order to cut off the root of the plant supported by the support base, it is not necessary to take out the plant from the support base, and the root of the plant can be cut out while the plant is placed on the support base. Well, you can harvest plant roots.

According to the above configuration, the cutting unit cuts off the root of the plant leaving a part of the root of the plant when the movable unit is pressed. Thus, the root of the plant can be harvested by suppressing the influence on the growth of the plant by cutting off the root of the plant without cutting all the roots of the plant and leaving a part of the roots. .

Thus, according to the above configuration, it is possible to suppress the influence on the growth of the plant cultivated by the plant cultivation apparatus and to efficiently harvest the root of the plant.

The present invention can be attached to a plant cultivating apparatus for cultivating a plant, and is arranged so that it can be pressed to a support base that supports the plant by a root cutting mechanism for cutting the root of the plant. The movable part is provided at the tip of the movable part, and a cutout part that cuts off the root of the plant leaving a part when the movable part is pressed down.

This has the effect of suppressing the influence on the growth of the plant cultivated by the plant cultivation apparatus and efficiently harvesting the roots of the plant.

[Embodiment 1]
(Configuration of hydroponic cultivation device with root cutting mechanism)
Hereinafter, a first embodiment of the root cutting mechanism of the present invention will be described.

(A) of FIG. 1 is sectional drawing showing the structure of the hydroponic cultivation apparatus 1 which concerns on this Embodiment, (b) is a top view of (a).

Hydroponic cultivation apparatus (plant cultivation apparatus) 1 is a plant cultivation apparatus that grows plants by hydroponics. In the present embodiment, it is assumed that garlic (plant) 30 is cultivated. The hydroponic cultivation apparatus 1 mainly includes a culture solution tank 2, a culture solution 3, a shelf board (support stand) 4, and a root cutting mechanism 10.

The root cutting mechanism 10 can be attached to the hydroponic cultivation apparatus 1 for cultivating plants, and is for cutting the roots of the plants cultivated by the hydroponic cultivation apparatus 1. The root cutting mechanism 10 cuts the roots of the plant so as not to cut all the roots of the plant cultivated by the hydroponic cultivation device 1 but to leave a part.

The root cutting mechanism 10 is arranged on the shelf plate 4 so that it can be pressed (movable part) 11, and is arranged at the tip of the cutter 11. A blade (cutting portion) 12 for cutting the root 32 of the garlic 30, a stopper (connecting member) 13 that is arranged on the shelf board 4 and is connected to the shelf board 4 so that the cutter 11 can be pressed down, and an elastic member And a cutting table 15 including a surface that comes into contact with the blade 17 when the cutter 11 is pressed down to the lower limit. In other words, of the relative positions of the cutter 11 with respect to the shelf plate 4, the position where the blade 17 contacts the surface of the cutting table 15 is the lower limit of the cutter 11.

The culture solution tank 2 is a water tank for storing the culture solution 3. The material of the culture solution tank 2 is not particularly limited, and is made of plastic, concrete, or the like. The culture solution 3 is a liquid fertilizer to which necessary nutrients are added according to the plant to be cultivated, and a commonly used liquid fertilizer can be used.

The shelf board 4 supports a plant that is cultivated by the hydroponic cultivation apparatus 1 and is also a support base that supports a cutter 11 that can be pressed as described later. The garlic 30 is placed and cultivated on the shelf board 4.

The material of the shelf board 4 may be any material that can stably place the plant to be cultivated and can be connected so that the cutter 11 can be pressed, and is made of foamed polystyrene.

In addition, as a material of the shelf board 4, as mentioned above, a lightweight material like a polystyrene foam is preferable. In particular, the shelf board 4 is preferably made of foamed polystyrene having high compression and increased strength. Thereby, since the intensity | strength of the shelf board 4 can be raised, even if the force which presses down the cutter 4 is added, it can prevent damaging.

The shelf plate 4 is provided with an opening 7 that can support a bulb (plant) 31 of the garlic 30 that is placed and can pass the root 32 of the garlic 30. . The size of the opening 7 provided in the shelf board 4 is determined according to the plant to be cultivated. When the garlic 30 is cultivated as in this embodiment, the diameter of the opening 7 is suitably about 1 to 5 cm, for example.

The shelf board 4 is installed at such a height that a space is provided between the liquid level of the culture solution 3 and the root of the root 32 of the garlic 30. Thus, by providing a space at the root of the garlic root 32, the portion exposed to the air in the root of the garlic root 32 easily absorbs oxygen. Thereby, the growth of the garlic 30 can be promoted.

Further, the shelf plate 4 is provided with a plurality of openings 17 for inserting the cutters 11. The opening 17 is provided in the shelf board 4 so as to have a shape corresponding to the shape of the blade 12. As will be described later, in the present embodiment, since a plurality of cutters 11 are provided, a plurality of openings 17 are also provided on the shelf plate corresponding to the plurality of cutters 11.

Further, the garlic 30 may be rooted by placing the bulb 31 of the garlic 30 on the shelf 4 as it is, but in the hydroponic cultivation apparatus 1, the bulb 31 of the garlic 30 placed on the shelf 4. Is covered with a protective member composed of the film 5 and the beads 6 so that the root portion is exposed. Thereby, drying of the bulb 31 of the garlic 30 can be prevented. The film 5 is made of, for example, a synthetic resin, and the beads 6 are made of, for example, expanded polystyrene.

Alternatively, a medium provided with an opening that allows passage of the roots of the plant to be cultivated may be provided on the shelf board 4, and the plant to be cultivated may be placed on the medium.

The cutter 11 is arranged so as to penetrate the shelf board 4, and is for cutting a portion below the shelf board 4 among the plants cultivated by the hydroponic cultivation apparatus 1.

The cutter 11 includes a plurality of cutters 11a, 11b, 11c, and 11d. The plurality of cutters 11a, 11b, 11c, and 11d are arranged around the bulb 31 of the garlic 30 supported by the shelf board 4, and can be pressed independently.

When the cutters 11a, 11b, 11c, and 11d are viewed in plan, the cutters 11a, 11b, 11c, and 11d are arranged around the bulb 31 of the garlic 30 supported by the shelf board 4 so as to be circular. Yes. In the hydroponic cultivation apparatus 1, cutters 11 a, 11 b, 11 c, and 11 d are arranged surrounding the outer periphery of the film 5 that covers the bulb 31 of the garlic 30.

The cutters 11a, 11b, 11c, and 11d are configured as a shape obtained by dividing a circular shape into four when viewed in plan.

The shelf 4 includes a plurality of openings 17a, 11a, 11b, 11c, and 11d as openings 17 into which the cutters 11a, 11b, 11c, and 11d that are arranged around the bulb 31 of the garlic 30 supported by the shelf 4 are inserted. 17b, 17c and 17d are provided. The cutters 11a, 11b, 11c, and 11d are inserted into the openings 17a, 17b, 17c, and 17d, respectively. That is, the openings 17a, 17b, 17c, and 17d are also provided on the shelf board 4 so as to surround the bulb 31 of the garlic 30 when viewed in plan so as to have a circular shape divided into four.

The configuration of the cutter 11 connected to the shelf board 4 will be described with reference to FIG. FIG. 2 is a diagram illustrating the configuration of the cutter 11 of the hydroponic cultivation apparatus 1. Since the cutters 11a, 11b, 11c, and 11d have the same configuration, the configuration of the cutter 11a will be described with reference to FIG.

The cutter 11a is arranged so as to pass through the opening 17a provided in the shelf board 4, and one end (pressing part) of the cutter 11a is placed on the surface of the shelf board 4 (the bulb 31 of the garlic 30 is mounted). And the spring 14 which is an elastic member.

The cutter 11 a is connected to the back surface of the shelf plate 4 (the surface facing the culture solution 3) by a stopper 13. As described above, the operability can be improved by providing the cutter 11 a with the spring 14 and the stopper 13.

The other end (tip portion) of the cutter 11a is provided with a blade 12 that cuts off the root 32 of the garlic 30 by leaving the cutter 11a pressed.

Thus, the cutters 11a, 11b, 11c, and 11d are arranged on the shelf plate 4 so that they can be pressed independently. For this reason, it is possible to press down the cutter corresponding to the location to be cut among the roots 32 of the garlic 30.

Further, as shown in FIG. 1A, the cutoff table 15 is installed in the culture solution tank 2 so as to be positioned below the garlic 30.

The material of the cutoff table 15 can be, for example, plastic such as polypropylene.

When the cutters 11a, 11b, 11c, and 11d are pressed down to the lower limit, the cutoff table 15 includes a surface that comes into contact with the blades 12 disposed on the cutters 11a, 11b, 11c, and 11d.

The distance between the surfaces of the cutoff table 15 gradually increases from the top to the bottom. Thereby, when the cutters 11a, 11b, 11c, and 11d are pressed, the blade 12 disposed on the cutter (for example, the cutter 11a) can be brought into contact with the surface of the cutting table 15. Therefore, the root 32 of the garlic 30 can be harvested by pressing the cutters 11a, 11b, 11c, and 11d. Specifically, in the present embodiment, the shape of the cutoff table 15 is a truncated cone, and its side surface is the surface.

(About root cutting)
Next, with reference to FIGS. 3 and 4, cutting the root will be described.

FIG. 3 is a diagram illustrating that the roots of plants cultivated by the hydroponic cultivation apparatus 1 are harvested.

In addition, the case where the cutter 11a is pushed down among the cutters 11a, 11b, 11c, and 11d will be described with reference to FIG.

The cutting table 15 is arranged such that its side surface comes into contact with the blade 12 arranged on the cutter 11a when the cutter 11a is pressed down to the lower limit. The cutting edge of the blade 12 is formed so as to be compatible with the side surface of the cutoff table 15.

The cutting table 15 which is a truncated cone is installed in the culture solution tank 2 so as to be located below the garlic 30.

For this reason, when the garlic 30 is placed on the shelf board 4, the roots 32 of the garlic 30 will extend along the side surface of the cutting table 15 as it grows. Thus, since the root 32 of the garlic 30 extends along the side surface of the cutting table 15, the root 32 of the garlic 30 is arranged between the blade 12 and the side surface of the cutting table 15. Then, as shown by the arrow in FIG. 3, the cutter 11 a corresponding to the portion to be harvested is pressed among the roots 32 of the garlic 30.

FIG. 4 is a cross-sectional view showing the hydroponic cultivation apparatus 1 in which some of the cutters 11 are pressed.

In the hydroponic cultivation apparatus in FIG. 4, the cutter 11a is pressed. The cutter 11c is not pressed. As shown in FIG. 4, among the cutters 11a, 11b, 11c, and 11d, the root 32 of the garlic 30 is pressed against the side surface of the cutting table 15 and cut by the blade 12 disposed on the pressed cutter 11a. .

Since the root cutting device of Patent Document 2 described above is configured to cut the root of the plant in the lateral direction, all the roots of the plant are cut. On the other hand, according to the root cutting mechanism 10 according to the present embodiment, since the cutter 11 is pushed in the vertical direction (vertical direction) instead of in the horizontal direction (horizontal direction), all the roots 32 of the garlic 30 are cut off. Instead, it can be partially left.

As described above, the plurality of cutters 11a, 11b, 11c, and 11d of the root cutting mechanism 10 are arranged so as to surround the garlic 30 supported by the shelf board 4, and can be pressed independently. It is. Therefore, among the cutters 11a, 11b, 11c, and 11d, the root 32 of the garlic 30 is cut only by the blade 12 that is disposed at the tip of the pressed cutter 11a, and the cutters 11b, 11c, and 11d are not pressed. Depending on the blade 12, the root 32 of the garlic 30 is not cut off. That is, the root 32 of the garlic 30 is harvested only by the blade 12 disposed on the pressed cutter 11a, and the other parts are left.

Therefore, according to the root cutting mechanism 10, the influence on the growth of the garlic 30 can be suppressed and the root 32 of the garlic 30 can be harvested.

Further, since the root cutting mechanism 10 includes the cutting base 15 including the side surface that comes into contact with the blade 12 disposed on the cutter 11a when the cutter 11a is pressed down to the lower limit, the root 32 of the garlic 30 is surely cut off. The roots 32 of garlic 30 can be harvested efficiently.

Moreover, as shown to (b) of FIG. 1, in hydroponic cultivation apparatus 1, when cutter 11a * 11b * 11c * 11d is planarly viewed, cutter 11a * 11b * 11c * 11d becomes circular shape. Thus, it arrange | positions surrounding the circumference | surroundings of the bulb 31 of the garlic 30 which the shelf board 4 supports.

Thus, the cutters 11a, 11b, 11c, and 11d are arranged around the bulb 31 of the garlic 30 in accordance with the shape of the truncated cone 15 that is a truncated cone. Can be brought into contact with the side surface of the cutting table 15, and the root 32 of the garlic 30 can be cut out reliably.

(Cut-off stand shape and cutter arrangement)
The cutoff table 15 is preferably conical for the following reasons.

First, the case where the shape of the cutoff table 15 is not a conical shape will be described with reference to FIGS.

(A) (b) of Drawing 5 is a figure showing the hydroponic cultivation apparatus provided with the cutting stand whose section shape is a rectangle, and (a) is a cutting stand whose side does not contact a pressed blade. (B) is a figure showing the hydroponic cultivation apparatus provided with the cutting stand which a side surface contacts with the pressed blade.

5A has a rectangular cross section. In other words, the shape of the cutoff table 115 is a columnar shape.

Further, the cutting table 115 has a circular shape so that the blade 12 disposed at the tip of the cutter 11 does not contact the side surface of the cutting table 115 even when the cutter 11 is pressed. In other words, when viewed in plan, the areas of the upper surface and the lower surface of the cutoff table 115 are smaller than the area of the circle formed by the cutters 11a, 11b, 11c, and 11d.

For this reason, even if the cutter 11 is pressed to cut the root 32 of the garlic 30 extending along the side surface of the cutting table 115, the blade 12 disposed on the cutter 11 and the side surface of the cutting table 115 The root 32 of the garlic 30 cannot be pressed, and the root 32 of the garlic 30 can hardly be cut.

Further, the cutting table 125 in FIG. 5B has a rectangular cross section. In other words, the shape of the cutoff table 125 is columnar.

The cutting table 125 has a circular shape such that when the cutter 11 is pressed, the blade 12 disposed at the tip of the cutter 11 and the side surface of the cutting table 125 come into contact with each other. In other words, when viewed in plan, the area of the upper surface and the lower surface of the cutting table 115 is larger than the area of the circle formed by the cutters 11a, 11b, 11c, and 11d.

For this reason, the roots 32 of the garlic 30 are intricately extended on the upper surface of the cutting table 125 arranged in the horizontal direction. For this reason, the roots 32 of the garlic 30 cut by the pressed blades 12 of the cutter 11 vary in cutting position and length, and the value as a product is reduced.

Moreover, since the root 32 of the garlic 30 extends in an intricate manner on the upper surface of the cutoff table 125, the cutter 11 does not necessarily exist below the blade 12 of the pressed cutter 11 a, such as the cutter 11 a. Absent. For this reason, the efficiency of harvesting falls.

On the other hand, as described in FIGS. 1A and 1B and FIG. 3, the cutoff table 15 provided in the root cutting mechanism 10 has a frustum shape.

Specifically, when viewed in plan, the area of the upper surface of the cutting table 15 is smaller than the area of the circle constituted by the cutters 11a, 11b, 11c, and 11d, and the area of the lower surface of the cutting table 15 is determined by the cutters 11a and 11b. -It is larger than the area of the circle constituted by 11c and 11d.

Further, when viewed in plan, the cutting table 15 has a truncated cone shape in accordance with the circular arrangement of the cutters 11a, 11b, 11c, and 11d.

Thus, the side surface of the cutting table 15 is configured to come into contact with the blade 12 disposed on the cutter 11 when the cutter 11 is pressed down to the lower limit.

For this reason, since the root 32 of the garlic 30 extended along the side surface of the cutting stand 15 can be cut | disconnected by the blade 12 distribute | arranged to the pressed cutter 11a, the length 32 is arranged and the root 32 of the garlic 30 is removed. The roots 32 of the garlic 30 can be harvested more reliably without reducing the value as a product.

Here, the cutting table 15 may be a cone shape, and is not limited to a truncated cone shape, and may be a cone shape. Further, as shown in FIGS. 6A to 6C, the cutting table 15 may be a polygonal frustum.

6 (a) to 6 (c) are plan views showing a hydroponic cultivation apparatus provided with a root cutting mechanism, (a) showing a hydroponic cultivation apparatus equipped with a triangular pyramid cutout stand, and (b). Represents a hydroponic cultivation apparatus equipped with a truncated pyramid cutout, and (c) represents a hydroponic cultivation apparatus equipped with a pentagonal truncated cutout.

As shown in FIG. 6A, the cutoff table 22 has a triangular frustum shape. The cutter 21 includes a plurality of cutters 21a, 21b, and 21c, and is inserted into the shelf board 4 so as to be triangular when viewed in plan.

Thus, the side surface of the cutting table 22 is configured so as to come into contact with the blade 12 disposed on the cutter 21 when the cutter 21 is pushed down to the lower limit.

As shown in FIG. 6B, the cutoff table 24 has a quadrangular pyramid shape. The cutter 23 includes a plurality of cutters 23a, 23b, 23c, and 23d, and is inserted into the shelf plate 4 so as to be square when viewed in plan.

Thus, the side surface of the cutting table 24 is configured to come into contact with the blade 12 disposed on the cutter 23 when the cutter 23 is pressed down to the lower limit.

As shown in FIG. 6C, the cutoff table 26 has a pentagonal pyramid shape. The cutter 25 includes a plurality of cutters 25a, 25b, 25c, 25d, and 25e, and is inserted into the shelf plate 4 so as to be a pentagon when viewed in plan.

Thus, the side surface of the cutting table 26 is configured to come into contact with the blade 12 disposed on the cutter 25 when the cutter 25 is pressed down to the lower limit.

Further, the cutting table 22, the cutting table 24, and the cutting table 26 may be a triangular pyramid, a quadrangular pyramid, and a pentagonal pyramid, respectively, and may be a hexagonal pyramid or a polygonal pyramid or a polygonal pyramid that is higher than the hexagonal pyramid. Good.

Thus, when the cutters 21a, 21b, 21c, 22a, 22b, 22c, and 23a, 23b, and 23c are viewed in plan, the cutters 21a, 21b, and 21c, 22a, 22b, and 22c, and 23a, 23b, and 23c are polygonal. It is arranged surrounding the bulb 31 of the garlic 30 supported by the shelf board 4 so as to have a shape.

Thus, the garlic 30 on which the shelf board 4 supports the cutters 21a, 21b, 21c, 22a, 22b, 22c, 23a, 23b, and 23c in accordance with the shapes of the cutting table 22, the cutting table 24, and the cutting table 26. The bulb 31 can be surrounded and arranged. Thereby, the root 32 of the garlic 30 can be surely cut by pressing each of the cutters 21a, 21b, 21c, 22a, 22b, 22c, 23a, 23b, and 23c.

However, for example, when a polygonal frustum is used like the cutting table 22 shown in FIG. 6A, when changing the number of divisions of the cutter 21 or the position at which the root 32 of the garlic 30 is cut, the shape of the cutting table 22 is also changed. Must be changed accordingly.

On the other hand, when the amount or position of the root 32 of the garlic 30 is changed by changing the shape of the cutting table 15 to a truncated cone or cone, the sizes of the cutters 11a, 11b, 11c, and 11d, that is, the cutter 11a. It is only necessary to change the size and number of the blades 12 arranged on each of 11b, 11c, and 11d, and it is not necessary to change the shape of the cutting table 15.

(A) (b) of Drawing 7 is a top view showing a hydroponic cultivation device provided with a plurality of cutters arranged circularly, (a) expresses a hydroponic cultivation device provided with a cutter divided into two, (B) is a figure showing the hydroponic cultivation apparatus divided into three.

7 (a), the cutter 27 is composed of two divided cutters 27a and 27b, and is inserted into the shelf plate 4 so as to be circular when viewed in plan. In this way, the side surface of the cutting table 15 is configured to come into contact with the blade 12 disposed on the cutter 27 when the cutter 27 is pressed down to the lower limit.

7 (b), the cutter 28 is composed of three divided cutters 28a, 28b, and 28c, and is inserted into the shelf board 4 so as to be circular when viewed in plan. In this way, the side surface of the cutting table 15 is configured to come into contact with the blade 12 disposed on the cutter 27 when the cutter 27 is pressed down to the lower limit.

Thus, by making it a truncated cone or a conical shape like the cutting table 15, it is possible to change the number of divisions and the size like the cutters 27 and 28 without changing the shape of the cutting table 15. The amount and position of the root 32 of the garlic 30 can be changed.

For this reason, like the cutting table 15, by making it a truncated cone or a cone shape, the cost increase is suppressed, and the balance between the effect on the growth of the garlic 30 and the yield of the roots 32 of the garlic 30 is balanced, Can be taken easily.

The cutters 11a, 11b, 11c, and 11d do not have to surround the circumference of the bulb 31 of the garlic 30 supported by the shelf board 4 as shown in FIGS. It suffices if it is arranged so as to surround a part of the bulb 31. Further, the cutters 11a, 11b, 11c, and 11d need not always be inserted into the openings 17a, 17b, 17c, and 17d, respectively.

That is, as shown in FIG. 8, when the root 32 of the garlic 30 is cut out of the cutters 11a, 11b, 11c, and 11d, for example, a necessary cutter such as the cutter 11a is inserted into the corresponding opening 17a. You may do it.

FIG. 8 is a diagram illustrating a state in which a cutter is inserted into any of a plurality of openings.

As described above, a plurality of cutters 11 a, 11 b, 11 c, and 11 d that surround and surround the bulb 31 of the garlic 30 supported by the shelf board 4 are inserted into the shelf board 4 of the hydroponic cultivation apparatus 1. A plurality of openings 17a, 17b, 17c, and 17d are provided, and at least one of the cutters 11a, 11b, 11c, and 11d (for example, the cutter 11a) is any of the openings 17a, 17b, 17c, and 17d. (For example, the opening 17a) may be inserted.

Thus, the cutter 11a can be disposed so as to surround a part of the bulb 31 of the garlic 30 supported by the shelf board 4.

Thus, by pressing the cutter 11a surrounding only a part of the bulb 31 of the garlic 30, only a part of the root 32 of the garlic 30 can be cut by the blade 12 arranged on the cutter 11a. Can leave a part of.

For this reason, the influence on the growth of garlic 30 can be suppressed, and the root 32 of garlic 30 can be harvested. In addition, it is possible to easily balance the suppression of the influence on the growth of the plant and the harvest amount of the root of the plant.

Further, when the shelf 4 is provided with an opening that is divided into four equal parts, such as the openings 17a, 17b, 17c, and 17d, the cutters 11a, 11b, 11c, and 11d that are inserted into the shelf 4 are provided. It is not necessary to prepare four, and only one of the equally divided parts such as the cutter 11a may be prepared. Thereby, the cost which manufactures the cutter 11 can be reduced.

(Summary)
Thus, the root cutting mechanism 10 for cutting the roots of a plant and attachable to a plant cultivation apparatus for cultivating plants is attached to the hydroponic cultivation apparatus 1. Then, the root cutting mechanism 10 includes the cutters 11a, 11b, 11c, and 11d and the tips of the cutters 11a, 11b, 11c, and 11d, which are arranged to be pressed on the shelf plate 4 that supports the garlic 30. And a blade 12 that cuts off the root 32 of the garlic 30 leaving a part when the cutters 11a, 11b, 11c, and 11d are pressed.

Thus, the cutters 11a, 11b, 11c, and 11d having the blades 17 disposed at the tips are arranged on the shelf plate 4 so that they can be pressed. Thereby, the root | root 32 of the garlic 30 which the shelf board 4 supports can be cut off by pressing down cutter 11a * 11b * 11c * 11d.

For this reason, in order to cut out the root 32 of the garlic 30 supported by the shelf board 4, it is not necessary to take out the garlic 30 from the shelf board 4, and the root 32 of the garlic 30 is cut out with the garlic 30 placed on the shelf board 4. Therefore, the roots 32 of garlic 30 can be efficiently harvested.

In addition, if all the roots 32 of the garlic 30 being cultivated are cut at a time, the garlic 30 may not absorb water and nutrients until new roots 32 grow, and the garlic 30 may be weakened or withered.

On the other hand, according to the above configuration, the blade 17 cuts out the root 32 of the garlic 30 while leaving any part of the root 32 of the garlic 30 by pressing one of the cutters 11a, 11b, 11c, and 11d. Thus, the root 32 of the garlic 30 is harvested by suppressing the influence on the growth of the garlic 30 by cutting out the root 32 of the garlic 30 without cutting all the roots 32 of the garlic 30 and leaving a part. be able to.

Thus, since the hydroponics apparatus 1 is equipped with the root cutting mechanism 10, it suppresses the influence which it has on the growth of the garlic 30 cultivated by the hydroponics apparatus 1, and the root of the garlic 30 efficiently. 32 can be harvested.

Moreover, in this Embodiment, the plant which the hydroponic cultivation apparatus 1 grows demonstrated as what is the garlic 30. FIG. However, the plant cultivated by the hydroponic device 1 to which the root cutting mechanism 10 is attached may be a plant that needs to harvest roots. For example, in addition to garlic, the root portion is used as a herbal medicine or a herbal medicine. Plants can be listed.

Furthermore, the root cutting mechanism 10 of this Embodiment should just be attached to the apparatus which grows a plant, for example, spray culture etc. which spray and grow a mist-like culture solution on a root other than the hydroponic cultivation apparatus 1 etc. You may attach to the apparatus of.

[Embodiment 2]
A second embodiment of the root cutting mechanism of the present invention will be described. For convenience of explanation, members having the same functions as those in the drawings described in Embodiment 1 are given the same reference numerals, and descriptions thereof are omitted.

FIG. 9 is a cross-sectional view showing a configuration of a hydroponic cultivation apparatus provided with a root cutting mechanism according to the second embodiment.

As shown in FIG. 9, the hydroponic cultivation apparatus 1 includes a root cutting mechanism 41. The root cutting mechanism 41 is different from the root cutting mechanism 10 in that it includes a cutting table 45 in place of the cutting table 15 and further includes a bubble generating tube (air stone) 46.

The root cutting mechanism 41 includes a cutter 11, a blade 12, a stopper 13, a spring 14, a cutoff table 45, and a bubble generating tube 46.

The bubble generating tube 46 is an air stone for supplying oxygen (gas) to the culture solution 3, and outputs oxygen as a large number of bubbles. The bubble generating tube 46 is connected to an air supply pump (not shown) provided outside the cutoff table 45 by a hollow tube 48.

Note that the bubble generation tube 46 may output oxygen to the culture solution 3 and may output a gas containing oxygen such as air as bubbles.

The cutting table 45 is installed in the culture solution tank 2 so as to be located below the garlic 30, similarly to the cutting table 15. The cutout table 45 has a bubble generating tube 46 disposed therein. A plurality of openings 47 through which oxygen output from the bubble generating tube 46 passes are provided on the side surface (surface) of the cutoff table 45. The shape, material, etc. of the cutting table 45 are the same as those of the cutting table 15.

Here, in hydroponics, it is known that when the oxygen concentration in the culture solution is increased, the roots of the plant being grown grow well.

Therefore, even when the bubble generating tube 46 is installed inside the cutting table 45 as in the root cutting mechanism 41, the roots 32 of the garlic 30 are formed by forming a plurality of openings 47 through which oxygen can pass through the cutting table 45. It is possible to effectively distribute oxygen to the part. According to the root cutting mechanism 41, oxygen can be effectively supplied to the roots 32 of the garlic 30 cultivated by the hydroponic cultivation apparatus 1 provided with the cutting table 45.

Further, as described above, the cutting table 45 has a cone shape such as a cone or a truncated cone. For this reason, in order to generate many bubbles by disposing the bubble generating tube 46 in the vicinity of the lower surface where the space inside the cutoff table 45 is large, the bubble generating tube 46 having a relatively large installation area is removed. Can be installed inside. In addition, since the side surface of the cutoff table 45 is inclined, oxygen bubbles output from the bubble generating tube 46 can be efficiently discharged in the culture solution over a wide range compared to the case where the side surface is vertical, such as a columnar shape. Can be dispersed. Thus, since the cutting stand 45 has a cone shape, oxygen can be efficiently supplied into the culture solution 3.

[Embodiment 3]
A third embodiment of the root cutting mechanism of the present invention will be described. For convenience of explanation, members having the same functions as those in the drawings described in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.

FIG. 10 is a cross-sectional view illustrating a configuration of a hydroponic cultivation apparatus including a root cutting mechanism according to the third embodiment.

As shown in FIG. 10, the hydroponic cultivation apparatus 1 includes a root cutting mechanism 51. The root cutting mechanism 51 is different from the root cutting mechanism 10 in that a cutter 52 is provided instead of the cutter 11 and a cutting stand 55 is provided instead of the cutting stand 15.

The root cutting mechanism 41 includes a cutter 52, a blade 12, a stopper 13, a spring 14, and a cutting table 55.

The cutter 52 is connected to the shelf 4 by the stopper 13, that is, between the portion where the stopper 13 is disposed in the cutter 52 and the tip portion where the blade 12 is disposed. The bent portion 53 is bent.

At the bent portion 53, the cutter 52 is bent into a key shape. That is, in the cutter 52, the bent portion 53 included in the direction from the portion fixed by the stopper 13 toward the tip portion is bent in the direction parallel to the shelf board 4 and toward the cut-out table 55, and further in the vertical direction. It is bent in the downward direction.

Moreover, the bending part 53 is not limited to the shape bent like said direction, For example, from the location currently fixed with the stopper 13 among the cutters 52, it is parallel to the shelf 4 and from the cutting stand 55 It may be a shape that is bent in a direction away from it and further bent in a downward direction in the vertical direction.

When cutting the root 32 of the garlic 30, it may be necessary to cut on the inner side or on the outer side than when cutting with the cutter 11.

Therefore, like the cutter 52, the bending portion 53 is provided, and the shape of the bending portion 53 is adjusted so that the blade 17 disposed on the cutter 52 and the blade 17 abut when the cutter 52 is pressed down. The relative position with the side surface (surface) of the base 55 can be changed. For this reason, the position which cuts off the root 32 of the garlic 30 can be adjusted. For this reason, the root cutting mechanism 51 can improve convenience compared to the root cutting mechanism 10.

The cutting stand 55 has a conical shape, and has a height such that the apex protrudes from the water surface of the culture solution 3 and is located near the root portion of the garlic 30.

Thus, the cutting table 55 has such a height that the apex is included in the opening 7 of the shelf board 4. For this reason, the distance between the apex of the cutting table 55 and the root portion of the garlic 30 can be reduced. Thereby, it can control so that the root 32 of the garlic 30 may spread evenly.

(A) of FIG. 11 is a perspective view showing a state of rooting from the scale 33, and (b) is a plan view showing a rooting portion of the scale.

As the garlic 30, the root 32 can be rooted from the scale 33 by placing one scale (plant) 33 on the shelf 4. As shown in FIGS. 11A and 11B, the root 32 roots in a circumferential shape from the lower part of the scale 33. For this reason, when the cutting stand 55 is configured as a truncated cone, the area of the upper base near the scale 33 is preferably smaller than the circumferential area surrounded by the root portion at the bottom of the scale 33.

Thereby, the root 32 of the scale 33 can be controlled to spread evenly on the side surface of the cutting stand 55.

Also, the root 32 can be cut at the root by making the apex of the cutting stand 55 closer to the root of the garlic 30.

FIG. 12 is a diagram illustrating a state of a hydroponic cultivation apparatus that cuts the root 32 in the air.

As shown in FIG. 12, it may be necessary to cut the root 32 in the air instead of in the culture solution 3. In such a case, in particular, the cutting table 55 needs to protrude above the water surface of the culture solution 3.

If the root (cut surface) of the cut root 32 is immersed in the culture solution 3, the root 32 may be discolored due to the bacteria in the culture solution 3, or the water quality of the culture solution 3 may be deteriorated. There is. In such a case, this can be prevented by cutting the root 32 in the air.

Also, the position of the root 32 of the garlic 30 to be cut can be adjusted by pressing the cutter 52 by adjusting the inclination angle of the side surface of the cutoff table 55.

The shape of the cutting stand 78 is a ridge shape raised in a streak shape. That is, the cutting stand 78 extends in the longitudinal direction of the culture medium tank 2 and is formed in a streak shape.

And the shape of the cutting stand 78 has a triangular cross section in a direction orthogonal to the direction extending in the above-mentioned streak shape (that is, the extending direction). In the cutting stand 78, the triangular slope is a side surface for contacting the blade 12 of the cutter 72. Thereby, the same effect as the cutoff stand 75 can be acquired.

Further, as shown in FIGS. 14 (a) and 14 (b) and the cutting tables 75 and 78 shown in FIG. 15, the shape is made into a bowl shape so that a root cutting mechanism for cutting the roots 32 of a plurality of plants 5 is obtained. The configuration can be easily expanded. That is, when mounting and cultivating a plurality of plants 5 on the shelf board 4, it can be configured as the cutting tables 75 and 78 common to the plurality of plants 5. For this reason, when mounting the some plant 5 on the shelf board 4, the space | interval and dense planting degree of the some plant 5 can be selected freely.

Further, the cutter 72 includes a cutter group 72A and a cutter group 72B. For this reason, similarly, it becomes easy to expand the device configuration to a root cutting mechanism for cutting the roots 32 of the plurality of plants 5. That is, when placing and cultivating a plurality of plants 5 on the shelf board 4, a cutter group 72 </ b> A composed of a plurality of cutters 72 arranged side by side in common with the plurality of plants 5 and a cutter group 72 </ b> B are configured. can do.
