Description

A fly larvae hatching and rearing system Technical Field

[0001] This invention belongs to the field of fly breeding technology and relates to a fly larvae hatching and breeding system. Background Technology

[0002] Flies are widely distributed and abundant. They are holometabolous insects, meaning their life cycle includes four stages: egg, larva (maggot), pupa, and adult. Fly larvae are particularly nutritionally complete, being high in protein, low in sugar and fat, and rich in minerals, vitamins, trace elements, and antibacterial substances, making them a high-quality animal protein feed. Furthermore, fly larvae have wide applications in medicine, health care, and food industries.

[0003] Fly larvae hatching and rearing is a technique that involves collecting fly eggs laid by flies during fly breeding and then hatching them into larvae for utilization. Currently, fly larvae hatching and rearing in my country is mainly done through artificial breeding. For example, a drawer-type maggot rearing cabinet disclosed in patent literature (application number: CN201520641808.8) includes a rectangular frame with multiple horizontal compartments welded or screwed inside. Each horizontal compartment is a rectangular angle iron frame, and drawers are placed inside each horizontal compartment. Except for the bottom, the sides and top of the drawers are enclosed with mesh or glass, and a maggot collection basin is provided on the bottom of the frame.

[0004] When this device is used for hatching and raising fly larvae, workers need to cultivate the collected fly eggs in ordinary plastic basins overnight each day. The next day, the plastic basins containing the collected fly eggs are placed in a drawer-type maggot-rearing cabinet to allow the fly eggs to hatch into fly larvae. When the fly larvae mature, they are allowed to crawl out naturally and fall into the maggot-collecting basin below. This breeding method requires a large amount of manual intervention, making it time-consuming, labor-intensive, and inefficient. It also has a low level of mechanization and automation, making it impossible to achieve large-scale, industrialized, and efficient production of fly larvae.

[0005] Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a fly larvae hatching and rearing system. This invention solves the problems of low automation and low rearing efficiency in existing fly larvae hatching and rearing methods, making it difficult to achieve large-scale production.

[0007] The objective of this invention can be achieved through the following technical solution: A fly larvae hatching and rearing system, comprising a breeding fly room and a rearing room, characterized in that the breeding fly room is provided with an egg-collecting conveyor line connected end to end, and the rearing room is provided with a rearing conveyor line connected end to end. Both the egg-collecting conveyor line and the rearing conveyor line are provided with receiving trays, and the number of receiving trays on the rearing conveyor line is greater than the number of receiving trays on the egg-collecting conveyor line. This fly larvae hatching and rearing system also includes a conveying and transfer device, wherein both the egg-collecting conveyor line and the rearing conveyor line can convey their respective receiving trays to the conveying and transfer device. The conveying and transfer device includes a first robotic arm and a second robotic arm, both capable of reciprocating between the egg-collecting conveyor line and the rearing conveyor line. The first robotic arm can transfer the receiving trays on the egg-collecting conveyor line to the rearing conveyor line by its own movement, and the second robotic arm can transfer the receiving trays on the rearing conveyor line to the egg-collecting conveyor line by its own movement.

[0008] This system uses egg-collecting and rearing conveyor lines in the breeding and rearing rooms, respectively. Flies lay their eggs in trays in the breeding room. After egg-collecting, all trays containing the eggs are transferred sequentially to the rearing conveyor line by a first robotic arm. Once the eggs hatch into larvae, the larvae are removed from the trays and collected, leaving empty trays. After cleaning, these empty trays are lined with suitable egg-collecting material, such as wheat bran mixed with an appropriate amount of water. Simultaneously, a second robotic arm transfers trays containing egg-collecting material from the first robotic arm to the rearing conveyor line, and this cycle continues.

[0009] Clearly, this system, through the combination of an egg-collecting conveyor line, a rearing conveyor line, and a transfer device, enables the automatic transfer of trays between the breeding fly house and the rearing house, automating both the egg-collecting and rearing processes and significantly reducing manual intervention, resulting in a high degree of automation. The transfer device employs a structure with two robotic arms working in tandem, allowing trays to be transferred simultaneously from the egg-collecting conveyor line to the rearing conveyor line. This greatly improves the efficiency of tray exchange, thus giving the system a high degree of automation and rearing efficiency. Furthermore, both the egg-collecting and rearing conveyor lines are interconnected, with the trays continuously moving along a closed loop. This allows for continuous egg-collecting, rearing, and tray transfer operations, further enhancing the system's automation and rearing efficiency, enabling large-scale production.

[0010] Furthermore, flies typically lay eggs at 9 AM and 5 PM, meaning the trays need to be exchanged twice a day. The first exchange must be done before 9 AM, and the second before 5 PM. However, the hatching time for fly eggs in the rearing room is generally 6-8 hours. This means there's a time difference between the hatching time in the rearing room and the time it takes for flies to lay eggs in the rearing room. The hatching time in the rearing room is also affected by factors like temperature and humidity. As a result, during system operation, there may be situations where the fly eggs on the rearing conveyor line haven't hatched into larvae when a tray exchange is needed. If the number of trays on the egg-collecting conveyor line and the rearing conveyor line is equal, then the exchange can only be done after the larvae have hatched into adults, significantly impacting rearing efficiency. Because the number of trays on the breeding conveyor line is greater than that on the egg-collecting conveyor line, this system ensures that when trays need to be exchanged, there are always some empty trays on the breeding conveyor line to be exchanged with those on the egg-collecting conveyor line, without waiting for the incubation process in the breeding room to be completed. This ensures that the system has higher breeding efficiency. Trays on the breeding conveyor line that have not yet completed the incubation of fly eggs remain in the breeding room until the incubation is completed. Then, the material in the trays is emptied, the trays are cleaned, and empty trays are left to be exchanged.

[0011] In summary, this fly larvae hatching and rearing system, through the coordination of the egg-collecting conveyor line, the rearing conveyor line, and the conveying and transfer device, and by combining the ratio of the number of receiving trays on the rearing conveyor line to the number of receiving trays on the egg-collecting conveyor line, can greatly improve the automation level and rearing efficiency of the fly larvae hatching and rearing system, enabling this system to meet the requirements of large-scale production.

[0012] In the above-mentioned fly larvae hatching and rearing system, the egg-collecting conveyor line and the rearing conveyor line are parallel to each other and in opposite directions at the conveying and transfer device, and the movement direction of the first manipulator and the second manipulator is perpendicular to the conveying direction of the egg-collecting conveyor line at the conveying and transfer device.

[0013] When the conveying and transferring device is in operation, the first and second robotic arms respectively pick up a set of containers from the egg-collecting conveyor line and the aquaculture conveyor line, creating an empty space on each line. Since the egg-collecting and aquaculture conveyor lines travel in opposite directions at the transfer device, after each line completes one stroke, the empty space on the egg-collecting conveyor line aligns with the second robotic arm, while the empty space on the aquaculture conveyor line aligns with the first robotic arm. The first robotic arm then moves the container containing fly eggs to the empty space on the aquaculture conveyor line, while the second robotic arm moves the container containing egg-collecting material to the empty space on the egg-collecting conveyor line, thus completing one exchange of containers. This cycle continues until all containers on the egg-collecting conveyor line and an equal number of containers on the aquaculture conveyor line have been exchanged.

[0014] The egg-collecting conveyor line and the aquaculture conveyor line are parallel to each other at the conveying and transfer device, and the moving direction of the first manipulator and the second manipulator is perpendicular to the moving direction of the egg-collecting conveyor line at the conveying and transfer device. This design ensures that the first manipulator and the second manipulator have the shortest travel distance during each transfer operation, and the distance traveled is fixed, thereby improving the stability, reliability and transfer efficiency of the device operation.

[0015] In the aforementioned fly larvae hatching and rearing system, this fly larvae hatching and rearing system also includes a fly replenishment room. The fly replenishment room has a first door and a second door, both of which are connected to the breeding fly room. The breeding fly room is equipped with a fly replenishment conveyor line, and the fly replenishment conveyor line is equipped with a fly replenishment tray that can move along its conveying direction. One section of the fly replenishment conveyor line enters the fly replenishment room through the first door and then returns to the breeding fly room through the second door.

[0016] Flies continuously die in the breeding room. By setting up a fly replenishment conveyor line that passes through the replenishment room, workers can replenish fly pupae in the replenishment trays and then use the conveyor line to transfer the pupae into the breeding room. The pupae hatch into flies in the breeding room, ensuring a sufficient number of flies in the breeding room, guaranteeing egg collection and efficiency, thereby improving the system's breeding efficiency and automating the fly replenishment process. Since the breeding room is full of flies, the fly replenishment room allows workers to perform the replenishment operation there, which is more convenient and hygienic.

[0017] In the aforementioned fly larvae hatching and rearing system, the conveying and transfer device is located inside the fly replenishment room, which also has a third doorway connected to the rearing room. One section of the egg-collecting conveyor line enters the fly replenishment room through the first doorway and returns to the breeding fly room through the second doorway. Another section of the rearing conveyor line enters the fly replenishment room through the third doorway and returns to the rearing room through the third doorway.

[0018] Since the breeding fly room is full of flies, a fly replenishment room is set up, and the conveying and transfer device is placed in the fly replenishment room. This allows both the egg collection conveyor line and the breeding conveyor line to pass through the fly replenishment room to transport the container tray to the conveying and transfer device. In this way, the conveying and transfer device is less likely to be disturbed by flies during operation, which can improve the stability and reliability of the conveying and transfer device. At the same time, it also makes it easier for staff to carry out daily operation and maintenance of the conveying and transfer device in the fly replenishment room.

[0019] In the aforementioned fly larvae hatching and rearing system, the egg-collecting conveyor line is located close to and along the wall of the breeding room. Since flies typically tend to lay eggs in corners or edges, the egg-collecting conveyor line positioned against the wall maximizes the use of flies' egg-laying habits, improving egg collection efficiency and thus increasing rearing efficiency.

[0020] In the aforementioned fly larvae hatching and rearing system, the rearing conveyor line extends in a meandering manner within the rearing room, and the number of receiving trays on the rearing conveyor line is at least twice the number of receiving trays on the egg-collecting conveyor line.

[0021] The breeding conveyor line extends in a circuitous manner within the breeding room, allowing for the placement of more trays and saving space. Preferably, the number of trays on the breeding conveyor line is twice the number on the egg-collecting conveyor line. This ensures that at least half of the trays on the breeding conveyor line are available for exchange with those on the egg-collecting conveyor line. This guarantees that each time the trays on the egg-collecting conveyor line collect fly eggs, there are always sufficient trays on the breeding conveyor line to exchange with all the trays on the egg-collecting conveyor line, thus resulting in higher breeding efficiency.

[0022] In the above-mentioned fly larvae hatching and breeding system, the breeding conveyor line is connected end to end at the conveying and transfer device, and the breeding room is also equipped with a feeding station, which is located at the middle of the length direction between the first and last ends of the breeding conveyor line.

[0023] The material unloading station is equipped with a material unloading robot, which can unload all the material in the container trays to the next process and then put the empty trays back into the breeding conveyor line. Of course, manual unloading can also be used at the material unloading station. The material unloading station is located in the middle of the length direction between the beginning and end of the breeding conveyor line, so that the breeding room is divided into breeding area and empty area. Half of the container trays are located in the breeding area for hatching larvae, and the other half of the container trays are empty and located in the empty area. The number of empty trays in the empty area is no less than the total number of container trays on the egg-receiving conveyor line. This ensures that there are always enough empty trays on the breeding conveyor line to exchange with all the container trays on the egg-receiving conveyor line.

[0024] In the aforementioned fly larvae hatching and rearing system, the fly replenishment room is equipped with a cleaning station. The fly replenishment room also has a fourth door and a fifth door that connect to the rearing room. The rearing conveyor line enters the fly replenishment room through the fourth door after passing the unloading station and then returns to the rearing room through the fifth door. The cleaning station is used to clean the receiving trays on the rearing conveyor line that enters the fly replenishment room through the fourth door.

[0025] The cleaning station can be used to clean the larvae collection trays using cleaning equipment such as cleaning nozzles or cleaning tanks, or it can be done manually. Cleaning the trays at the station prevents residual impurities and contaminants from negatively impacting the subsequent egg-collecting process, thus improving the efficiency and quality of egg collection. Since the rearing room is used for larval incubation, the temperature is relatively high, the smell is strong, and the hygiene conditions are poor. Therefore, placing the cleaning station within the fly-catching room facilitates the cleaning of the trays and allows staff to easily operate and maintain the cleaning equipment.

[0026] In the aforementioned fly larvae hatching and rearing system, fly curtains are installed at both the first and second entrances. Workers need to enter the fly-filling room to add feed, pupae, operate and maintain equipment. By installing fly curtains, flies from the breeding fly room can be prevented from flying into the fly-filling room, thus ensuring that the fly-filling room is not easily disturbed by flies and improving the hygiene conditions of the fly-filling room.

[0027] In the aforementioned fly larvae hatching and rearing system, the fly-catching room is also equipped with a feeding station for adding egg-laying material to the containing trays. The rearing conveyor line enters the fly-catching room through the third entrance, passes through the feeding station, and then transports the containing trays to the conveying and transfer device. The feeding station lays a layer of egg-laying material at the bottom of the containing trays, such as wheat bran mixed with an appropriate amount of water. This attracts flies to lay eggs in the containing trays, improving egg-laying efficiency. The fly-catching room is less susceptible to fly interference and has better hygiene conditions; therefore, placing the feeding station inside the fly-catching room facilitates the feeding process.

[0028] Compared with existing technologies, this fly larvae hatching and rearing system has the following advantages:

[0029] 1. This invention provides a fly larvae hatching and rearing system, belonging to the field of fly rearing technology. It solves the problems of low automation and low rearing efficiency in existing fly larvae hatching and rearing methods, making large-scale production difficult. This fly larvae hatching and rearing system includes a breeding fly room, a rearing room, and a conveying and transferring device. The breeding fly room is equipped with an egg-collecting conveyor line connected end-to-end, and the rearing room is equipped with a rearing conveyor line connected end-to-end. Both the egg-collecting and rearing conveyor lines are equipped with receiving trays, with the number of receiving trays on the rearing conveyor line exceeding the number on the egg-collecting conveyor line. Both the egg-collecting and rearing conveyor lines can transport their respective receiving trays to the conveying and transferring device, which includes a first robotic arm and a second robotic arm that can reciprocate between the egg-collecting and rearing conveyor lines. This invention improves the automation level and rearing efficiency of the fly larvae hatching and rearing system, enabling the system to meet the requirements of large-scale production.

[0030] Both the egg collection and aquaculture conveyor lines adopt an end-to-end structure. The container tray moves continuously along the closed loop on the egg collection and aquaculture conveyor lines, enabling the system to perform continuous egg collection, aquaculture, and container tray transfer operations. This improves the system's automation level and aquaculture efficiency, allowing the system to achieve large-scale production.

[0031] 2. This fly larvae hatching and rearing system, through the coordination of the egg-collecting conveyor line, the rearing conveyor line, and the conveying and transfer device, and by combining the ratio of the number of holding trays on the rearing conveyor line to the number of holding trays on the egg-collecting conveyor line, can greatly improve the automation level and rearing efficiency of the fly larvae hatching and rearing system, enabling this system to meet the requirements of large-scale production.

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] As shown in Figure 1, this fly larvae hatching and rearing system includes a breeding fly room 1, a rearing room 2, and a replenishment fly room 7. The breeding fly room 1 has an egg-collecting conveyor line 3 connected end-to-end, positioned close to and along the wall of the breeding fly room 1. The rearing room 2 has a rearing conveyor line 4 connected end-to-end. Both the egg-collecting conveyor line 3 and the rearing conveyor line 4 are equipped with receiving trays 5. The rearing conveyor line 4 extends meanderingly within the rearing room 2, and the number of receiving trays 5 on the rearing conveyor line 4 is greater than the number of receiving trays 5 on the egg-collecting conveyor line 3. In this embodiment, the number of receiving trays 5 on the egg-collecting conveyor line 3 is 600, and the number of receiving trays 5 on the rearing conveyor line 4 is 1200. In actual production, the number of receiving trays 5 can be adjusted according to the production scale. Generally, the number of receiving trays 5 on the rearing conveyor line 4 is at least twice the number of receiving trays 5 on the egg-collecting conveyor line 3.

[0040] As shown in Figures 1 and 2, this fly larvae hatching and rearing system also includes a conveying and transfer device 6. Both the egg-collecting conveyor line 3 and the rearing conveyor line 4 can convey their respective receiving trays 5 to the conveying and transfer device 6. The conveying and transfer device 6 includes a first robotic arm 61 and a second robotic arm 62, both of which can reciprocate between the egg-collecting conveyor line 3 and the rearing conveyor line 4. The first robotic arm 61 can transfer the receiving trays 5 on the egg-collecting conveyor line 3 to the rearing conveyor line 4 through its own movement, and the second robotic arm 62 can transfer the receiving trays 5 on the rearing conveyor line 4 to the egg-collecting conveyor line 3 through its own movement.

[0041] As shown in Figures 1 and 2, the fly replenishment room 7 has a first entrance 8 and a second entrance 9, both connected to the breeding fly room 1. The breeding fly room 1 is equipped with a fly replenishment conveyor line 10, on which a fly replenishment tray 11 is mounted that can move along its conveying direction. One section of the fly replenishment conveyor line 10 enters the fly replenishment room 7 through the first entrance 8 and returns to the breeding fly room 1 through the second entrance 9. Flies in the breeding fly room 1 will continuously die. By setting up the fly replenishment conveyor line 10 so that it passes through the fly replenishment room 7, workers can replenish fly pupae in the fly replenishment tray 11 and then use the fly replenishment conveyor line 10 to transfer the pupae into the breeding fly room 1. The pupae hatch into flies in the breeding fly room 1, thus ensuring that the number of flies in the breeding fly room 1 meets the requirements.

[0042] As shown in Figures 1 and 2, the conveying and transferring device 6 is located inside the fly-catching room 7. The fly-catching room 7 also has a third doorway 12 connecting to the breeding room 2. One section of the egg-collecting conveyor line 3 enters the fly-catching room 7 through the first doorway 8 and returns to the breeding fly room 1 through the second doorway 9. One section of the breeding conveyor line 4 enters the fly-catching room 7 through the third doorway 12 and returns to the breeding room 2 through the third doorway 12. Fly-blocking curtains 17 are installed at both the first doorway 8 and the second doorway 9. By setting up fly-blocking curtains 17, flies in the breeding fly room 1 can be prevented from flying into the fly-catching room 7, thereby ensuring that the fly-catching room 7 is not easily disturbed by flies and improving the sanitary conditions of the fly-catching room 7.

[0043] As shown in Figures 1 and 2, the breeding conveyor line 4 is connected end-to-end at the conveying and transfer device 6. The breeding room 2 also has a feeding station 13, which is located at the midpoint of the length of the breeding conveyor line 4 between its beginning and end. The feeding station 13 is equipped with a feeding robot that can empty all the material from the receiving tray 5 to the next process and then return the empty tray to the breeding conveyor line 4. Alternatively, the feeding station 13 can be manually filled. The fly-catching room 7 has a cleaning station 16. The fly-catching room 7 also has a fourth doorway 14 and a fifth doorway 15 connecting to the breeding room 2. After passing the feeding station 13, the breeding conveyor line 4 enters the fly-catching room 7 through the fourth doorway 14 and returns to the breeding room 2 through the fifth doorway 15. The cleaning station 16 is used to clean the receiving trays 5 on the breeding conveyor line 4 that enter the fly-catching room 7 through the fourth doorway 14. The cleaning station 16 can clean the receiving tray 5 using cleaning equipment such as cleaning nozzles or cleaning tanks, or it can be cleaned manually. Cleaning the receiving tray 5 through the cleaning station 16 can prevent residual impurities and contaminants in the receiving tray 5 from having an adverse effect on the subsequent egg collection process, thereby improving the efficiency and quality of egg collection.

[0044] As shown in Figures 1 and 2, the fly-catching room 7 is also equipped with a feeding station 18 for adding egg-collecting material to the container 5. The breeding conveyor line 4 enters the fly-catching room 7 through the third door 12, passes through the feeding station 18, and then transports the container 5 to the conveying and transfer device 6. The feeding station 18 lays a layer of egg-collecting material at the bottom of the container 5. The egg-collecting material, such as wheat bran, is mixed with an appropriate amount of water, which can attract flies to lay eggs in the container 5 and improve the egg-collecting efficiency.

[0045] The working principle of this fly larvae hatching and rearing system is as follows: First, the fly breeding room 1 is filled with flies. The flies lay their eggs in the receiving trays 5 on the egg-laying conveyor line 3. After the egg-laying is completed, the egg-laying conveyor line 3 sequentially transports the receiving trays 5 to the conveying and transfer device 6. The conveying and transfer device 6 sequentially transfers all the receiving trays 5 on the egg-laying conveyor line 3 to the rearing conveyor line 4. At the same time, an equal number of receiving trays 5 are transferred from the rearing conveyor line 4 to the egg-laying conveyor line 3.

[0046] The collection trays 5 containing fly eggs are placed on the breeding conveyor line 4 for incubation. After the fly eggs hatch into larvae, the breeding conveyor line 4 sequentially transports the collection trays 5 to the unloading station 13. The unloading station 13 pours out the material containing larvae from the collection trays 5, collecting and utilizing the larvae, resulting in empty collection trays 5. The empty collection trays 5 are then cleaned at the cleaning station 16 and transported to the feeding station 18. The feeding station 18 lays egg-collecting material suitable for fly egg laying in the collection trays 5, such as wheat bran mixed with an appropriate amount of water. After the flies have laid their eggs in the collection trays 5 on the egg-collecting conveyor line 3, the collection trays 5 are exchanged again, and this cycle continues.

[0047] As shown in Figures 3 to 5, the conveying and transferring device 6 has an egg-collecting conveyor line 3 and aquaculture conveyor line 4 that are parallel to each other and have opposite conveying directions. In Figures 3 to 5, the straight arrows indicate the conveying direction of either the egg-collecting conveyor line 3 or the aquaculture conveyor line 4. The first robotic arm 61 and the second robotic arm 62 of the conveying and transferring device 6 move in a direction perpendicular to the conveying direction of the egg-collecting conveyor line 3 at the conveying and transferring device 6. In practice, hangers are arranged along the conveying direction on the egg-collecting conveyor line 3 and the aquaculture conveyor line 4, and the receiving tray 5 is placed on the hangers. At this time, the first robotic arm 61 and the second robotic arm 62 transfer the receiving tray 5 by gripping the hangers. Of course, the first robotic arm 61 and the second robotic arm 62 can also directly grip the receiving tray 5 to transfer it.

[0048] When the conveying and transferring device 6 is in operation, as shown in Figure 3, the first robotic arm 61 and the second robotic arm 62 respectively pick up a set of receiving trays 5 from the egg-collecting conveyor line 3 and the breeding conveyor line 4. At this time, an empty space is formed on the egg-collecting conveyor line 3 and the breeding conveyor line 4. Since the egg-collecting conveyor line 3 and the breeding conveyor line 4 convey in opposite directions at the conveying and transferring device 6, after the egg-collecting conveyor line 3 and the breeding conveyor line 4 have each traveled one stroke, as shown in Figure 4, the empty space on the egg-collecting conveyor line 3 is aligned with the second robotic arm 62, while the empty space on the breeding conveyor line 4 is aligned with the first robotic arm 61. Then, as shown in Figure 5, the first robotic arm 61 moves the receiving tray 5 containing fly eggs to the empty space on the breeding conveyor line 4, while the second robotic arm 62 moves the receiving tray 5 containing egg-collecting material to the empty space on the egg-collecting conveyor line 3, thus completing one exchange and transfer of the receiving trays 5. This process continues until all the trays 5 on the egg-collecting conveyor line 3 are exchanged with an equal number of trays 5 on the aquaculture conveyor line 4.
