To this end, the apparatus for breeding fly larvae of the present invention comprises: a fly habitat; a larvae-breeding area installed in the fly habitat; and a lid covering an upper portion of the larvae-breeding area, wherein the larvae-breeding area includes a pillar unit installed on the bottom of the fly habitat, and multiple breeding chambers installed in the pillar unit such that the breeding chambers operate independently.

## Background
TECHNICAL FIELD
The present invention relates to an apparatus for consecutively breeding fly larvae, and in particular to an apparatus for consecutively breeding fly larvae which makes it possible to automatically breed larvae by repeatedly performing a process wherein in a state where a breeding chamber is divided into a plurality of breeding chambers configured to breed larvae in, the grownup larvae with the exception of those having escaped to a metamorphosis chamber are collected, and the larvae who escaped to the metamorphosis chamber are grown into flies, and the flies move to a habitat chamber installed above the breeding chambers and are bred and oviposit in the breeding chamber.
BACKGROUND ART
Generally speaking, fly larvae, more specifically, maggot are rich in protein, so they are usually used as feed or fishing bait.
According to a modern medical treatment, it is reported that maggot are inputted in a wounded portion where it is hard to conduct a surgical operation or where it is impossible to cure cleanly, for thereby curing rotten portions when the wound is severe or it is hard to distinguish dead skin from living skin.
There is not much provided the facility which is configured to enable a mass production of fly larvae which are being widely used in a variety of fields.
The Korean Patent Registration No. 10-0654253 describes “apparatus for breeding fly” configured so as to improve the above descried problems.
According to the Korean Patent Registration No. 10-0654253, a larvae breeding box is secured to a conveyor belt and is moved by one room per day, so the larvae may be bred under the controls of various breeding apparatuses which are fixed to the top and provide a proper habitat environment to each larvae growth stage.
However, the above-described related art has problems in that since the breeding box wherein larvae are grown is configured to drive, the amount of feed may increase due to the growth in terms of management, and it is hard to treat excretion, which results in decreased breeding efficiency.
As the fly larvae grow, their weights sharply increase, which needs to increase the capacity of facilities. The larvae may have big stress due to noise and vibrations during the operations of the fly breeding apparatus. Since the metamorphosis chamber is not directly connected, the grownup larvae should be manually selected and moved into the metamorphosis chamber, thus leading to bad work efficiency.
According to the above-described related art, in the related fly breeding apparatus, since the breeding box in which fly larvae inhabit is secured to the conveyer belt and is driven, the quality of breeding larvae is not much as compared with the facilities, and facility maintenance costs a lot. As a breeding facility designed to consecutively breed larvae in large quantity in a narrow space, the economic and feasibility and efficiency are bad.
In order to improve the above mentioned problems, the applicant of the present application has the Korean Patent Registration No. 10-1044636 of “apparatus for consecutively breeding larvae”.
According to the Korean Patent Registration No. 10-1044636, seven independent breeding chambers are secured to one another in a circle, and various facilities are mounted on a cover which is identified as top of the breeding chambers. The consecutive breeding may be performed under a control management wherein feed are supplied at each growth stage as the cover rotates and forwardly moves stage by stage, and a habitat environment is maintained and controlled.
However, the Korean Patent Registration No. 10-1044636 has disadvantages in that since the breeding chambers are arranged in a circle, the area of the breeding chamber increases, and the management is hard and space application is bad.

The operations of the apparatus for consecutively breeding larvae according to the present invention will be described.
FIGS. 7A and 7B are views illustrating the operations of an apparatus for consecutively breeding fly larvae according to the present invention.
As illustrated therein, the apparatus for consecutively breeding larvae 100 according to the present invention is partly the same as in the Korean Patent Registration No. 10-104636 invented by the same applicant as the present application, so the descriptions on the same components will be omitted. Only the different operations will be described.
In the present invention, the separately arranged first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g are arranged in quadrangle shapes, which leads to using the optimized space of the fly habitat camber 110 of the fly habitat part 110 and to producing as much larvae as possible.
The flies move from the fly habitat chamber 112 into any of the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g which is not covered by any of the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f among the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e of the larvae breeding part 210, more specifically, the flies move from the fly habitat chamber 112 into the seventh breeding chamber 310g whose top is not covered by the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f and oviposit.
Among the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g, the seventh breeding chamber 310a is called a chamber where the flies oviposit.
In a state where the flies oviposit in the seventh breeding chamber 310g of the larvae breeding part 21, the locking member 530 is unlocked after one day, and the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f ascend by the ascending and descending member 530, and the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g move along the rail 216, to the next stage by one room.
The seventh breeding chamber 310g where the flies have oviposited moves to the position of the neighboring first breeding chamber 310a, and the first breeding chamber 310a moves to the position of the second breeding chamber 310b. More specifically, the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g each move by one room per day in the above described manner, and the larvae grown in the sixth breeding chamber 310f are collected, and after the collection is finished, the sixth breeding chamber 310f moves to the position of the seventh breeding chamber 310g. 
While the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g each move to the next stage per day, when the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g complete moving, the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f which have ascended or descend by means of the ascending and descending member and are locked by the locking member 530 and at the same time cover tops of the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f. 
The locking member 530 is unlocked whenever one day passes, and the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f ascend, and at the same time the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f move by one room thus providing optimized habitat environment for each growth stage of larvae. The larvae are grown in the larvae breeding part 210 until sixth days when the larvae may be products.
At this time, the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f installed on tops of the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f may be set from the first day to the sixth day of larvae growth depending on the positions of the tops of the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f. 
The method for making good growth environment so that the larvae may grow under comfort and sanitary environments by days in the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f using the devices installed in the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f is described in the Korean Patent Registration No. 10-104636, so the descriptions thereon will be omitted.
On the sixth day when the growth of larvae is completed, the opening and closing door 313 installed in the sixth breeding chamber 310f is opened for thereby opening the passage 312. The grownup larvae come out of the opened passage 312 and move through the connection passage 612, to the metamorphosis chamber 614 while heading for the light from the connection passage 612.
At this time, the larvae who move through the connection passage 612, to the metamorphosis chamber 614 passes through the electronic scale sensor 616 installed in the metamorphosis chamber 614.
While the larvae headed for the metamorphosis chamber 614 passes through the electronic scale sensor 616, when the larvae reach a predetermined weight level, the opening and closing door 313 is automatically closed based on the sensing of the electronic scale sensor 616, and the passage 312 is closed.
Part of the larvae bred in the sixth breeding chamber 310f moves through the passage 312, to the metamorphosis chamber 614 and metamorphose into flies, and the metamorphosed flies move into the habitat chamber 112 and inhabit therein and move into the seventh breeding chamber 310g and oviposit therein.
The flies oviposit, and the larvae grow until sixth day, and part of the larvae of the sixth day move into the metamorphosis chamber 614 and metamorphose into flies, and the metamorphosed flies inhibit in the fly habitat chamber 112 and move into the seventh breeding chamber 310g whose top is open and oviposit therein. The above-described process is repeatedly performed, thus consecutively producing larvae.
As a means for discharging outside the secretion or the excretion generating during the growth of larvae, the suction discharge unit 410 is same as in the Korean Patent Registration No. 10-104636 which is invented by the same applicant as the present application, so the detailed descriptions thereon will be omitted.
The first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g are arranged in quadrangle shapes and are configured to move along the rail 216, thus utilizing to the max the space of the fly habitat chamber 112, which results in producing as much larvae as possible.
It is possible to prevent overload to the apparatus for consecutively breeding larvae 100 in such a way that the first through sixth covers 510a, 510b, 510c, 510d, 510e and 510f are configured to ascend or descend in place by means of the ascending and descending member 520, and only the first to seventh breeding chambers 310a, 310b, 310c, 310d, 310e, 310f and 310g are configured to move by room whenever alarm generates per day along the rail 216.
In a space in the floor of the sealed fly breeding chamber 112, the larvae breeding chamber 210 and the fly metamorphosis chamber 614 are installed for thereby providing the optimized habitat environment. The larvae with the exception of those having escaped to the metamorphosis chamber are collected, and the metamorphosed flies move into the fly habitat part 110 and oviposit therein, the ecological circulation cycles of which are repeatedly performed, thus consecutively producing good larvae.
As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
