Description

Technical Field

[0001] The utility model belongs to the technical field of fly breeding and relates to a fly larvae breeding system. Background Art

[0002] Flies are widely available and abundant. They undergo complete metamorphosis, with a life cycle consisting of four stages: egg, larva (maggot), pupa, and adult. Fly larvae offer a comprehensive nutritional profile, high in protein, low in sugar, and low in fat. They are also rich in minerals, vitamins, trace elements, and antimicrobial substances, making them a high-quality animal protein feed. Furthermore, fly larvae have a wide range of applications in medicine, healthcare, and food.

[0003] Fly larvae farming is a technique that involves collecting fly eggs laid by flies during the fly farming process and then hatching them into larvae for use. Currently, fly larvae farming in my country is mainly done artificially. For example, a patent document discloses a drawer-type maggot farming cabinet (application number: 201520641808.8), which includes a rectangular frame with multiple horizontal partitions welded or screwed inside. Each horizontal partition is a rectangular angle iron frame, with drawers placed inside. Except for the bottom of the frame, the sides and top of the other drawers are enclosed with gauze or glass, and a maggot basin is provided on the bottom of the frame.

[0004] When used for fly larvae hatching and breeding, this device requires workers to incubate the eggs in ordinary plastic basins overnight each day. The next day, the plastic basins containing the eggs are placed in a drawer-type maggot breeding cabinet, where they hatch into fly larvae. When the larvae mature, they are allowed to naturally crawl out and fall into the maggot collection basin below. This breeding method requires a lot of manual intervention, is time-consuming and labor-intensive, has low breeding efficiency, and has low levels of mechanization and automation, making it impossible to achieve large-scale, industrialized, and efficient production of fly larvae. Summary of the Invention

[0005] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose a fly larvae breeding system. The utility model solves the problems that the existing fly larvae breeding methods have low automation and breeding efficiency and are difficult to achieve large-scale production.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A fly larvae breeding system, characterized in that the fly larvae breeding system includes a conveying and transferring device, a material pouring station, a cleaning station and a breeding conveyor line connected end to end, and a plurality of receiving trays are arranged in sequence along the conveying direction of the breeding conveyor line, and the breeding conveyor line can convey the receiving tray to the material pouring station, the cleaning station and the conveying and transferring device in sequence, the material pouring station is used to pour out the material in the receiving tray, the cleaning station is used to clean the receiving tray, and the conveying and transferring device can remove the receiving tray on the breeding conveyor line and replace it with a new receiving tray.

[0007] In this system, a breeding conveyor line is provided so that a tray containing fly eggs is cultured on the breeding conveyor line. After the fly eggs hatch into larvae, the breeding conveyor line transports the tray to a material unloading station, where the material containing the larvae is unloaded from the tray for collection and utilization, leaving an empty tray. The empty tray is then cleaned at a cleaning station. The breeding conveyor line then transports the tray to a conveying and transfer device, where egg-catching material suitable for fly egg laying is laid in the tray. The egg-catching material, such as wheat bran with an appropriate amount of water, is added. As the tray containing fly eggs is transferred to the breeding conveyor line, the conveying and transfer device simultaneously removes the tray containing the egg-catching material for egg catching, and the cycle continues.

[0008] Obviously, this system uses the form of a breeding conveyor line combined with a conveying and transferring device to enable the receiving trays to automatically move within the breeding conveyor line. In this way, all the receiving trays can be added to the breeding conveyor line through the conveying and transferring device. At the same time, all the receiving trays on the breeding conveyor line can also be removed by the conveying and transferring device for egg collection. This method realizes the automation of the breeding process, greatly reduces human intervention, and has a high degree of automation. The breeding conveyor line adopts an end-to-end structure, and the receiving trays continuously move along the closed loop on the breeding conveyor line, allowing this system to realize continuous breeding operations and receiving tray transfer operations, thereby improving the degree of automation and breeding efficiency, and enabling this system to achieve large-scale production.

[0009] In the aforementioned fly larvae breeding system, the number of trays between the feeding end of the breeding conveyor line and the unloading station is equal or approximately equal to the number of trays between the unloading station and the removal end of the breeding conveyor line. The unloading station is equipped with an unloading robot capable of unloading all the material from the trays. Manual unloading is also possible. The unloading robot can utilize existing technology and include a robotic arm that grips the trays and then unloads the material from them. The receiving trays on the breeding conveyor line become empty trays after passing through the unloading station. Since the number of receiving trays between the feeding end of the breeding conveyor line and the unloading station is equal to or approximately equal to the number of receiving trays from the unloading station to the removal end of the breeding conveyor line along the conveying direction of the breeding conveyor line, half of the empty trays can be left on the breeding conveyor line. In this way, if the receiving trays have been filled with fly eggs in the previous process, but the fly eggs on the breeding conveyor line have not yet hatched into larvae, there is no need to wait for the completion of the hatching process in the breeding room. Instead, the receiving trays with fly eggs can be fed into the breeding conveyor line at the same time as the reserved empty trays are removed from the breeding conveyor line for receiving eggs. This ensures that the system has higher breeding efficiency. The receiving trays that have not completed the hatching of fly eggs are still left in the breeding room until the hatching is completed, and then the materials in the receiving trays are poured out, and the receiving trays are cleaned to form empty receiving trays to be replaced.

[0010] In the aforementioned fly larvae breeding system, the fly larvae breeding system further includes a breeding room and a fly-catching room. The breeding conveyor line is located within the breeding room and extends in a circuitous manner. The conveying and transferring device is located within the fly-catching room. The fly-catching room has a first doorway connected to the breeding room. A section of the breeding conveyor line enters the fly-catching room through the first doorway and then returns to the breeding room through the first doorway. Because the breeding room requires larvae breeding, the corresponding temperature is high, the odor is foul, and the sanitary conditions are poor. However, because the fly-catching room does not require fly breeding, egg laying, or hatching, it can maintain better sanitary conditions. Therefore, the conveying and transferring device is located within the fly-catching room, so that the breeding conveyor line passes through the fly-catching room to transport the receiving tray to the conveying and transferring device. This facilitates daily operation and maintenance of the conveying and transferring device.

[0011] In the above-mentioned fly larvae breeding system, the cleaning station is arranged in the fly feeding room, and the fly feeding room also has a second door and a third door connected to the breeding room. After passing through the unloading station, the breeding conveyor line enters the fly feeding room through the second door and then returns to the breeding room through the third door. The cleaning station is used to clean the receiving tray on the breeding conveyor line entering the fly feeding room through the second door.

[0012] The cleaning station can clean the receiving tray using a cleaning nozzle, but manual cleaning is also possible. When using cleaning nozzles, several cleaning nozzles can be installed in different locations within the spray room. The cleaning nozzles can spray water outward. When the receiving tray passes through the spray room, the nozzles in different locations spray and clean the receiving tray simultaneously. Cleaning the receiving tray using the cleaning station can prevent the adverse effects of residual impurities and contaminants in the receiving tray on the subsequent egg collection process, thereby improving the efficiency and quality of egg collection. Setting the cleaning station in the fly replenishing room can facilitate the cleaning of the receiving tray and facilitate the daily operation and maintenance of the cleaning equipment by staff.

[0013] In the above-mentioned fly larvae breeding system, the conveying and transferring device includes a first manipulator and a second manipulator. The first manipulator is used to remove the receiving tray from the breeding conveyor line, and the second manipulator is used to add a new receiving tray to the breeding conveyor line. In actual circumstances, hangers are arranged along the breeding conveyor line along its conveying direction, and the top of the hanger is hung on the breeding conveyor line, and the receiving tray is placed on the hanger. At this time, the first manipulator and the second manipulator can remove or add the receiving tray by grabbing the hanger, removing the hanger from the breeding conveyor line or hanging the hanger on the breeding conveyor line. Of course, the first manipulator and the second manipulator can also directly grab the receiving tray to transfer the receiving tray.

[0014] In the aforementioned fly larvae breeding system, the fly-catching room also features a feeding station for adding egg-laying material to the holding tray. The breeding conveyor line enters the fly-catching room through the first entrance and passes through the feeding station before transporting the holding tray to the conveying and transfer device. This feeding station coats the bottom of the holding tray with a layer of egg-laying material, such as wheat bran, mixed with an appropriate amount of water. This attracts flies to the holding tray for egg-laying, improving egg-laying efficiency. The fly-catching room is less susceptible to interference from flies and offers better sanitary conditions. Therefore, placing the feeding station within the room facilitates the feeding process.

[0015] Compared with the existing technology, the fly larvae breeding system has the following advantages:

[0016] 1. This system uses a breeding conveyor line in conjunction with a conveyor transfer device, allowing the holding trays to automatically move within the breeding conveyor line. This allows all holding trays to be added to the breeding conveyor line via the conveyor transfer device, and all holding trays on the breeding conveyor line can also be removed by the conveyor transfer device for egg collection. This method automates the breeding process, significantly reducing manual intervention and achieving a high degree of automation.

[0017] 2. The breeding conveyor line adopts an end-to-end structure, and the receiving tray moves continuously along the closed loop on the breeding conveyor line, so that the system can realize continuous breeding operation and receiving tray transfer operation, thereby improving the degree of automation and breeding efficiency, so that the system can achieve large-scale production.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, the fly larvae breeding system includes a breeding house 8, a breeding house 6, and a fly replenishing house 7. The breeding house 8 is provided with an egg receiving conveyor line 13 connected end to end against the wall. A number of receiving trays 5 are sequentially arranged on the egg receiving conveyor line 13 along its conveying direction. The breeding house 6 is provided with a breeding conveyor line 4 connected end to end. A number of receiving trays 5 are sequentially arranged on the breeding conveyor line 4 along its conveying direction. The fly replenishing house 7 is provided with a conveying and transferring device 1. Both the egg receiving conveyor line 13 and the breeding conveyor line 4 can convey the receiving trays 5 to the conveying and transferring device 1. The breeding house 6 is provided with a material unloading station 2, and the fly replenishing house 7 is provided with a cleaning station 3. The breeding conveyor line 4 passes through the material unloading station 2 and the cleaning station 3 in sequence. The material unloading station 2 is used to pour out the material in the receiving tray 5, and the cleaning station 3 is used to clean the receiving tray 5.

[0024] like Figure 1 and Figure 2 As shown, the breeding conveyor line 4 is connected end to end at the conveying transfer device 1, and the unloading station 2 is correspondingly arranged in the middle of the length direction of the breeding conveyor line 4 between the head end and the tail end, so that along the conveying direction of the breeding conveyor line 4, the number of accommodating trays 5 between the feeding end of the breeding conveyor line 4 and the unloading station 2 is equal to or approximately equal to the number of accommodating trays 5 from the unloading station 2 to the removal end of the breeding conveyor line 4.

[0025] like Figure 1 and Figure 2 As shown, the breeding conveyor line 4 is located within the breeding room 6 and extends in a circuitous manner. The conveying and transferring device 1 is located within the fly-catching room 7. The fly-catching room 7 has a first doorway 9 connected to the breeding room 6. A section of the breeding conveyor line 4 enters the fly-catching room 7 through the first doorway 9 and then returns to the breeding room 6 through the first doorway 9. The conveying and transferring device 1 is arranged within the fly-catching room 7 so that the breeding conveyor line 4 passes through the fly-catching room 7 to transfer the receiving tray 5 to the conveying and transferring device 1. This facilitates the daily operation and maintenance of the conveying and transferring device 1. The fly-catching room 7 also has a second doorway 10 and a third doorway 11 connected to the breeding room 6. After passing through the unloading station 2, the breeding conveyor line 4 enters the fly-catching room 7 through the second doorway 10 and then returns to the breeding room 6 through the third doorway 11. The cleaning station 3 is used to clean the receiving tray 5 on the breeding conveyor line 4 that enters the fly-catching room 7 through the second doorway 10. The conveying and transferring device 1 includes a first manipulator 1a and a second manipulator 1b. The first manipulator 1a is used to remove the accommodating tray 5 on the breeding conveyor line 4, and the second manipulator 1b is used to add a new accommodating tray 5 to the breeding conveyor line 4.

[0026] like Figure 1 and Figure 2 As shown, the fly-repairing room 7 is further provided with a feeding station 12 for adding egg-receiving materials into the receiving tray 5. The breeding conveyor line 4 enters the fly-repairing room 7 from the first door 9 and passes through the feeding station 12, and then conveys the receiving tray 5 to the conveying transfer device 1.

[0027] The working principle of this system is as follows: first, the fly breeding room 8 is full of flies, and the flies lay fly eggs in the receiving trays 5 on the egg-receiving conveyor line 13. After the egg-laying is completed, the egg-receiving conveyor line 13 sequentially transports the receiving trays 5 to the transport transfer device 1. The transport transfer device 1 sequentially replenishes all the receiving trays 5 on the egg-receiving conveyor line 13 into the breeding conveyor line 4, and at the same time transfers an equal number of receiving trays 5 from the breeding conveyor line 4 to the egg-receiving conveyor line 13.

[0028] The receiving tray 5 with the collected fly eggs is then incubated on the breeding conveyor line 4. After the fly eggs have hatched into larvae, the breeding conveyor line 4 sequentially transports the receiving tray 5 to the material discharging station 2. The material discharging station 2 pours out the material with larvae in the receiving tray 5, collects and utilizes the larvae, and forms an empty receiving tray 5. After being cleaned by the cleaning station 3, the empty receiving tray 5 is transported to the feeding station 12. The feeding station 12 lays egg-catching material suitable for fly egg laying in the receiving tray 5. The egg-catching material, such as wheat bran, is added with an appropriate amount of water. After the eggs in the receiving tray 5 on the egg-catching conveyor line 13 are completed, the receiving tray 5 is exchanged again, and the cycle continues.

[0029] Example 2

[0030] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: there is no need to set up an egg-receiving conveying line 13 in the fly breeding room 8, but a frame is set up, and a number of receiving trays 5 are placed on the frame. The receiving trays 5 with fly eggs can be transferred to the conveying transfer device 1 by a robot or manually for exchange with the receiving trays 5 on the breeding conveying line 4.
