Therefore, the water held inside the water supply belt can be supplied to living things by using the movement of the conveyor belt.

Japanese Patent Application Publication No. 2021-151190

By the way, recent research into mass production and rearing of organisms has shown that by distributing water to all organisms, cannibalism due to lack of water can be avoided, contributing to increasing the survival rate of organisms and increasing the amount collected. ing. Therefore, in the design of this type of breeding device, there is a need for a technique that increases the efficiency of breeding organisms by ensuring a desired water supply function for the organisms.

However, if a string-like or band-like member such as a water supply belt is used as in the rearing device of Patent Document 1, it is not possible to secure a sufficient water supply area, and especially when there are a large number of organisms to be reared, the It is difficult to distribute water throughout the area. When water supply zones dry out due to natural drying, water shortages occur, which can lead to cannibalism. However, if an excessive amount of water is supplied to the water supply zone beyond its capacity to hold water, it is assumed that the rearing area will be submerged and the organisms will drown. Therefore, when using a member such as a water supply zone, it is difficult to manage the amount of water supply, and problems may arise in that it is difficult for living things to obtain a stable water supply.

The present disclosure aims to provide a rearing device that allows creatures such as insects to obtain a stable water supply.

One aspect of the present disclosure is
A breeding device for breeding living things,
a breeding case having a breeding area for the living thing and a wall section dividing the breeding area;
a water supply member provided along at least one wall of the breeding case so as to face the breeding area;
A breeding device comprising:
It is in.

In the breeding device of the above embodiment, the breeding area of the breeding case is divided by walls, and the living things are raised in this breeding area. Moreover, the water supply member forms a water supply field for living things in the rearing area. By providing this water supply member along at least one wall of the rearing case, the water supply member can have a surface structure having a wide water supply surface.

Since the water supply member has a wide water supply surface, a sufficient water supply area can be secured, and even when there are a large number of organisms to be raised, it is possible to distribute water to all the organisms. As a result, living things can calmly receive water from the wide water supply surface of the water supply member, and cannibalism of living things due to lack of water can be suppressed.

According to the above-described aspect, it is possible to provide a rearing device that allows living things such as insects to stably obtain water supply.

(Embodiment 1)
1. Object to be bred The living thing to be bred is, for example, a small creature such as an arthropod. The breeding target is, for example, an organism used for food, feed, research, or the like. For example, insects such as crickets, locusts, and grasshoppers can be raised. In particular, the organisms to be reared are arthropods that undergo incomplete metamorphosis, in which larvae directly metamorphose into adults, and larvae that undergo incomplete metamorphosis are particularly preferred. In this example, among insects, crickets and locust larvae of the order Grasshopper order will be described as suitable examples of organisms to be reared. However, adults (completely metamorphosed arthropods that have emerged) may be reared. Further, the breeding device may be used for breeding from eggs or for breeding organisms after hatching.

2. Basic Configuration of Breeding Apparatus As shown in FIG. 1, the breeding apparatus 1 of Embodiment 1 is used to raise a living creature C to be reared. In FIG. 1, a cricket, which is a type of insect, is illustrated as an organism C. The breeding device 1 includes, as its basic configuration, a breeding case 10, a water supply member 17, a breeding unit 20, a water supply section 30, and a transport device 40.

The breeding case 10 is placed on the installation surface for the breeding device 1. This breeding case 10 is formed using a plurality of frames. The plurality of frames include two first frames 11 provided on both end sides in the third direction Z, two second frames 12 that connect the two first frames 11, and two first frames 11 that connect the two first frames 11. two third frames 13 that connect the two first frames 11, and two fourth frames 14 that connect the two first frames 11. The two second frames 12 are spaced apart in the second direction Y and extend parallel to the third direction Z, which is the longitudinal direction. The two third frames 13 are spaced apart in the second direction Y and extend parallel to the third direction Z, which is the longitudinal direction. The two fourth frames 14 are spaced apart in the second direction Y and extend parallel to the third direction Z, which is the longitudinal direction.

The breeding case 10 has a plurality of walls that partition a breeding area 10a that is a breeding space for the living creatures C. The plurality of wall parts include side wall parts 16 provided on both sides of the rearing area 10a in the second direction Y, a holding part 21 located above the rearing area 10a, and a covering part that covers the rearing area 10a from other directions. (not shown for convenience). For this reason, the rearing area 10a is a closed space that is always closed during the rearing period, and this closed space is appropriately set to an environment suitable for the growth of the living organisms C.

3. Internal Structure of the Breeding Case The breeding case 10 is configured to accommodate the breeding unit 20 in the breeding area 10a. FIG. 1 illustrates a case where two breeding units 20 of the same shape (ie, a first breeding unit 20A and a second breeding unit 20B) are accommodated in the breeding area 10a. The first breeding unit 20A and the second breeding unit 20B are housed in the breeding area 10a in a state where they are juxtaposed in the third direction Z. Since the first rearing unit 20A and the second rearing unit 20B have the same shape, in FIG. 1, for convenience of explanation, the entire first rearing unit 20A is shown as a solid line, and the second rearing unit 20B is shown as a part thereof. Only the holding portion 21 is shown with a two-dot chain line. Note that the number of breeding units 20 accommodated in the breeding area 10a is not limited to two, and may be one or three or more.

The two second frames 12 of the breeding case 10 are support elements for supporting the breeding unit 20 so as to be slidable in the third direction Z. For this reason, a plurality of support rollers 15 are provided along the third direction Z on the inner surface of each second frame 12 in the second direction Y. Each support roller 15 is a rotatable member such as a roller or a bearing, and is configured to rotate upon receiving an input in the third direction Z.

4. Structure of Breeding Unit As shown in FIGS. 1 and 2, the breeding unit 20 includes a holding part 21 and a plurality of stop members 22.

The holding portion 21 is a plate-shaped member whose thickness direction is the first direction X. This holding portion 21 is configured to serve as a wall portion (top plate portion) that partitions the upper side of the rearing area 10a. The stop member 22 is for the creature C to stop in the rearing area 10a. The plurality of stop members 22 are fixed to the holding part 21 and are configured to form a hideout for the living creature C. For this reason, the breeding unit 20 having the plurality of stop members 22 is also referred to as a "hideout unit".

As shown in FIG. 2, when the breeding apparatus 1 of FIG. The portion 22a extends downward to hang down to a lower end portion 22b. The plurality of stop members 22 are arranged in the second direction Y with gaps 23 having the same size in between. That is, the plurality of stop members 22 are arranged at substantially equal intervals in the second direction Y. The gap 23 is dimensioned to allow movement of the creature C and to serve as a hideout depending on the body size of the creature C.

The stop member 22 is a plate-like member that extends in the first direction X along a plane defined by the first direction X and the third direction Z, with the second direction Y as the plate thickness direction. The perching member 22 is configured so that the living creature C to be reared can perch on its surface. The stop member 22 may be formed into a flat plate shape or may be formed into a corrugated shape. In this example, the stop member 22 is formed into a flat plate shape.

The material of the stop member 22 is not particularly limited, and for example, metals such as iron and aluminum, resin, rubber, wood, paper, etc. can be used as appropriate. It is preferable that the stop member 22 has a mesh structure in which a large number of through holes are formed over the entire surface so as to serve as a scaffold for the living creature C. For example, the stop member 22 can be formed of punched metal, wire mesh, or the like.

5. Structure of Water Supply Member As shown in FIGS. 2 and 3, the water supply member 17 is provided along the side wall portion 16 of the breeding case 10 so as to face the breeding area 10a. That is, the water supply member 17 is provided along one wall of the rearing case 10. This water supply member 17 is a sheet-like sheet member whose thickness direction is the second direction Y, and is configured to extend in the first direction X, which is the vertical direction, along the vertical surface, which is the inner surface of the side wall portion 16. There is. The water supply member 17 absorbs water and temporarily retains it inside.

The water supply member 17 has a main body portion 17c that serves as a substantial water supply source for the living organisms C between the upper portion 17a and the lower portion 17b. By providing the water supply member 17 on the side wall portion 16 along the vertical surface thereof, there is an advantage that feces, carcasses, etc. of the living creatures C are less likely to remain in the main body portion 17c, which is the water supply field. Further, by arranging the water supply member 17 along the vertical surface of the side wall portion 16, it is possible to prevent the rearing area 10a from becoming significantly narrower due to the arrangement of the water supply member 17.

The water supply member 17 may be configured as a single sheet member that covers the entire or part of the inner surface of the side wall portion 16, or the water supply member 17 may be configured as a single sheet member that covers the entire or a part of the inner surface of the side wall portion 16. May be constructed. As the surface shape of the water supply member 17, various shapes such as a flat surface, a curved surface, an uneven surface, a stepped surface, etc. can be adopted.

The material of the water supply member 17 is not particularly limited, and various water-retentive materials that can absorb water and temporarily hold it inside can be used. Typically, a material called "gauze" made of natural materials such as silk, cotton, linen, or chemical fibers can be used as a material that is relatively inexpensive and has excellent water absorption.

6. Structure of Water Supply Unit As shown in FIG. 3, the water supply unit 30 functions to supply water to the water supply member 17. The water supply section 30 is configured to supply water from both sides of the upper part 17a and lower part 17b of the water supply member 17. This water supply section 30 includes a drip nozzle 31, an on-off valve 32, and a water storage tray 33.

The drip nozzle 31 is for supplying water to the water supply member 17 from the upper part 17a side thereof, and is arranged directly above the upper part 17a in a downward state so as to drip water from above the upper part 17a of the water supply member 17. has been done. Further, an on-off valve 32 is provided upstream of this drip nozzle 31. The opening/closing valve 32 has its opening/closing timing and valve opening degree automatically adjusted as appropriate by a sequencer (not shown). Thereby, the supply water can be dripped from the dripping nozzle 31 onto the upper part 17a of the water supply member 17 in an amount according to the user's intention at a timing according to the user's intention.

Note that the water supply section 30 has a structure in which water is automatically supplied from the dripping nozzle 31 using an on-off valve 32, but instead of this structure, a manual on-off valve is used in place of this on-off valve 32, The user may manually operate the manual on-off valve.

The water storage tray 33 is for supplying water to the water supply member 17 from its lower portion 17b side. This water storage tray 33 is box-shaped with a bottom, and is provided directly below the lower part 17b of the water supply member 17. This water storage tray 33 is configured to be able to store water for soaking the lower part 17b of the water supply member 17. According to this configuration, the lower portion 17b of the water supply member 17 is immersed in the water collected in the water storage tray 33.

As shown in FIG. 3, water dripped from the dripping nozzle 31 to the upper part 17a of the water supply member 17 is absorbed by the upper part 17a, and then flows down to the lower part 17b along the main body part 17c according to gravity (Fig. 3 (See "Downward flow Fa" in By using the drip nozzle 31, water can be supplied to the water supply member 17 using a simple structure.

When an amount of water exceeding the water retention capacity of the water supply member 17 is dripped from the drip nozzle 31, the surplus water that cannot be retained in the water supply member 17 flows down from the lower part 17b of the water supply member 17 and accumulates in the water storage tray 33. The water accumulated in the water storage tray 33 is sucked up by the lower part 17b according to the capillary phenomenon in the water supply member 17, and is absorbed into the main body part 17c (see "upward flow Fb" in FIG. 3).

In this way, the main body portion 17c of the water supply member 17 becomes almost uniformly wet. Therefore, the surface of the main body portion 17c can be used as a water supply surface, and a wide range of this water supply surface can be used as a water supply field for the living creatures C.

In this embodiment, when the rearing area 10a side is inside and the opposite side is outside in the second direction Y, the water storage tray 33 is configured such that the height of the outside wall 33b is lower than the height of the inside wall 33a. It is configured. According to this configuration, overflow wastewater overflowing from the water storage tray 33 due to excessive water supply is collected in the collection container 34 (see FIG. 2) placed in advance below the water storage tray 33. Thereby, overflow drainage water overflowing from the water storage tray 33 can be prevented from leaking into the rearing area 10a of the rearing case 10.

Note that it is preferable to provide a function to automatically replace the water accumulated in the water storage tray 33. This function can be implemented, for example, by arranging the water storage tray 33 in an inclined state so that the old water that has accumulated in the water storage tray 33 is automatically discharged as overflow drainage and replaced with new water, or the old water that has accumulated in the water storage tray 33 is This is achieved by adopting a structure that forcibly drains some of the water using a drainage pump (not shown). This makes it possible to prevent old water from remaining in the water storage tray 33 for a long period of time and causing bad odors.

As shown in FIG. 4, the water supply member 17 has an upper portion 17a extending in the second direction Y, which is the thickness direction, and a lower portion 17b, which is a portion excluding the upper portion 17a, and a dimension in the second direction Y of the upper portion 17a. and the dimension in the second direction Y of the main body portion 17c. That is, the upper part 17a of the water supply member 17 is a widened part whose width in the second direction Y is increased by bending. On the other hand, the lower part 17b and the main body part 17c of the water supply member 17 have substantially the same dimensions in the second direction Y. By making the upper part 17a of the water supply member 17 a widened part, the receiving surface for receiving the water dripped from the dripping nozzle 31 can be expanded, which helps to reliably receive the water dripped from the dripping nozzle 31.

As shown in FIGS. 2 and 3, the breeding apparatus 1 of the first embodiment includes an intrusion prevention member 18. This intrusion prevention member 18 is for preventing the creatures C from intruding from the rearing area 10a into the installation area 10b of the water storage tray 33. The intrusion prevention member 18 is a plate-shaped member having a predetermined thickness, and is tilted and leans against the conveyance surface 42a of the conveyor belt 42 and the main body portion 17c of the water supply member 17.

When the rearing area 10a is inside the rearing case 10, the water storage tray 33 can be placed outside the rearing case 10 by providing the intrusion prevention member 18. The term "outside the rearing case 10" as used herein refers to an area that the creature C cannot access from the rearing area 10a. According to this intrusion prevention member 18, it is possible to prevent living things C from entering the installation area 10b of the water storage tray 33, entering the water stored in the water storage tray 33, and drowning.

The intrusion prevention member 18 has an access passage 18a that allows the living organisms C to move between the conveyance surface 42a of the conveyor belt 42 and the water supply member 17 in the rearing area 10a. In this embodiment, the access passage 18a is formed so as to extend linearly by one side of the intrusion prevention member 18 facing the rearing area 10a.

The intrusion prevention member 18 of this embodiment not only has an intrusion prevention function of preventing creatures C from entering the water storage tray 33, but also has a connection function of connecting the rearing area 10a and the water supply member 17. For this reason, this intrusion prevention member 18 is also referred to as a "connection member." According to this connection function of the intrusion prevention member 18, the living creature C can freely move between the conveyance surface 42a of the conveyor belt 42 and the water supply member 17. In particular, it becomes easier for living organisms C on the conveying surface 42a of the conveyor belt 42 to access the water supply member 17 through the access passage 18a of the intrusion prevention member 18 for water supply.

Note that the intrusion prevention member 18 is not limited to a plate-shaped member. Instead of using a plate-like member as the intrusion prevention member 18, for example, an arch-like member or a step-like member may be used.

As shown in FIGS. 2 and 3, the rearing device 1 of the first embodiment includes an escape prevention member 19 for the living creature C. This escape prevention member 19 is provided on the upper part 17a of the water supply member 17, and is fixed to the side wall part 16 so that the upper part 17a of the water supply member 17 is sandwiched between it and the side wall part 16 of the rearing case 10.

The escape prevention member 19 has a shape similar to a so-called "mouse return". That is, the escape prevention member 19 has a substantially L-shape when the breeding apparatus 1 in FIG. It has a protruding piece 19a (see FIG. 4). Therefore, the escape prevention member 19 can prevent the living organisms C from moving from the main body portion 17c side of the water supply member 17 to the upper portion 17a side. As a result, the creature C can be prevented from climbing the water supply member 17 from the rearing area 10a of the rearing case 10 and escaping to the outside of the rearing case 10 over the upper part 17a.

Note that the shape of the escape prevention member 19 is not limited to a substantially L-shape. Various shapes can be adopted as the shape of the escape prevention member 19 as long as the purpose of preventing or suppressing the escape of the living creatures C from the rearing area 10a can be achieved.

7. Structure of Transport Device As shown in FIG. 1, the breeding device 1 includes a transport device 40 below the breeding area 10a of the breeding case 10. The conveyance device 40 includes a pair of

rollers

41, 41 arranged apart from each other in the third direction Z, an endless conveyor belt 42 that is stretched over the pair of

rollers

41, 41, and a motor that drives one of the rollers 41. 43.

In the conveyance device 40, when the motor 43 drives one roller 41 and this roller 41 rotates around a rotation axis extending in the second direction Y, the conveyance surface 42a of the conveyor belt 42 continuously moves in the conveyance direction. do. The conveyance surface 42a of the conveyor belt 42 forms the floor surface (bottom surface) of the rearing area 10a.

Here, the conveying direction of the conveying device 40 means the moving direction of the conveying surface 42a of the conveyor belt 42. The motor 43 and the

rollers

41, 41 may be rotatable in only one direction or may be rotatable in both directions. That is, when the motor 43 is rotatable in only one direction, the transport direction of the transport device 40 is one of the third directions Z. When the motor 43 is rotatable in both directions, the transport direction of the transport device 40 is both the third direction Z.

The transport device 40 carries at least one of the following: the living creature C itself to be reared, food and water supply materials for the living creature C, shells and dead bodies of the living creature C, eggs of the living creature C in the early stage of growth, feces, food residue, and dust. It serves the function of transporting one object. For example, the transport device 40 can be used to transport food and water supplies from the outside into the rearing area 10a.

8. Operation of breeding unit The operation of the breeding unit 20 in the breeding apparatus 1 having the above configuration will be explained with reference to FIG. 5. In this embodiment, the two rearing

units

20A and 20B operate in the same way, so in the following explanation, for convenience, only the operation of the first rearing unit 20A will be explained, and the operation of the second rearing unit 20B will be explained. Omitted.

As shown in FIG. 5, the living creature C is reared in the rearing area 10a of the rearing case 10 during the rearing period. At this time, the first rearing unit 20A is placed at the initial position P1. Then, when the breeding period for the creature C ends, the collection work begins. In this collection work, an operation of sliding the first rearing unit 20A in the transport direction Z1 is performed.

If the first rearing unit 20A does not have a self-propelled means, the operator can slide the first rearing unit 20A in the transport direction Z1 by directly grasping the first rearing unit 20A with fingers and moving it manually. can be done. On the other hand, when the first rearing unit 20A is provided with a driving means such as an actuator, the first rearing unit 20A can be automatically slid in the transport direction Z1 using the driving means.

The first rearing unit 20A slides in the transport direction Z1 with both ends of the holding part 21 in the third direction Z being supported from below by a plurality of support rollers 15. The first breeding unit 20A is carried out from the breeding case 10 from the initial position P1 through the carrying-out preparation position P2. The living organisms C are then collected from the first rearing unit 20A that has been carried out.

Next, the effects of the first embodiment described above will be explained.

In the breeding device 1 of the first embodiment, the breeding area 10a of the breeding case 10 is divided by two side walls 16 on both sides in the second direction Y, and the living creature C is raised in this breeding area 10a. Further, the water supply member 17 forms a water supply field for the living creatures C in the rearing area 10a. If this water supply member 17 is provided along the side wall portion 16 of the rearing case 10, the water supply member 17 can have a surface structure having a wide water supply surface. Therefore, the living creatures C to be kept can calmly receive water from the wide water supply surface of the water supply member 17, and even when there are many living creatures C, it is possible to distribute water to all the living creatures C.

Since the water supply member 17 has a wide water supply surface, a sufficient water supply area can be ensured, and even when there are a large number of organisms C to be reared, it is possible to distribute the water supply to all the organisms C. As a result, the living creatures C can calmly receive water from the wide water supply surface of the water supply member 17, and cannibalism of the living creatures C due to water shortage can be suppressed.

Therefore, according to the first embodiment described above, it is possible to provide the breeding apparatus 1 that can stably supply water to the living creature C to be bred.

As an example of a modification particularly related to the first embodiment, instead of the intrusion prevention member 18, a structure may be adopted in which two separate members have each of the two functions that the intrusion prevention member 18 also serves. You can also do it. That is, a dedicated first member having an intrusion prevention function to prevent the living organisms C from entering the water storage tray 33 and a dedicated second member having a connection function to connect the rearing area 10a and the water supply member 17 are provided. It can be done.

Hereinafter, other embodiments related to the first embodiment described above will be described with reference to the drawings. In other embodiments, the same elements as those in Embodiment 1 are given the same reference numerals, and descriptions of the same elements will be omitted.

(Embodiment 2)
As shown in FIG. 6, the breeding apparatus 2 of the second embodiment differs from the breeding apparatus 1 of the first embodiment in that a water supply member 17 is provided at an additional location.

That is, the water supply member 17 is provided so as to face the breeding area 10a along the side wall portion 16 of the breeding case 10, and also to face the breeding area 10a along the holding portion 21 of the breeding unit 20. It is set up to do so. At this time, the holding part 21 is configured as an upper wall part that partitions the breeding area 10a of the breeding case 10.

Although not particularly illustrated, the water supply member 17 provided on the lower surface of the holding part 21 is extended to extend through the water supply member 17 to the upper surface of the holding part 21, and water is supplied to the water supply member 17 from above the holding part 21. can be configured to drip.

The other configuration of the rearing device 2 is the same as that of the first embodiment.

According to the rearing device 2 of the second embodiment, water supply for the living organisms C is achieved by providing the water supply member 17 not only on the side wall portion 16 of the rearing case 10 but also on the holding portion 21 which is the upper wall portion of the rearing case 10. You can increase the number of places.

Other than that, the same effects as in Embodiment 1 are achieved.

As a modification particularly related to the second embodiment, it is also possible to adopt a structure in which the water supply member 17 provided on the side wall portion 16 of the breeding case 10 is omitted in the breeding apparatus 2.

(Embodiment 3)
As shown in FIG. 7, in addition to the intrusion prevention member 18, the breeding device 3 of Embodiment 3 also includes a breeding area 10a of the breeding case 10 (in particular, both ends of the plurality of stop members 22 in the second direction Y). The breeding apparatus 1 is different from the breeding apparatus 1 of the first embodiment in that it includes a connecting member 18A that connects the side stop member 22) and the water supply member 17.

The connecting member 18A is a plate-shaped member having a predetermined thickness like the intrusion prevention member 18, and is provided so as to extend in the second direction Y. On the other hand, this connecting member 18A is different from the intrusion prevention member 18 which also serves the above-mentioned two functions, and is dedicated to connecting the rearing area 10a and the water supply member 17. Both surfaces (upper surface and lower surface) of the connecting member 18A in the first direction X serve as access passages 18a through which the living creature C can move.
