Description

Technical Field

[0001] This invention relates to the field of soldier fly farming technology, specifically to a three-dimensional, layered, continuous feeding system for full-cycle soldier fly farming. Background Technology

[0002] As a resource insect, the black soldier fly is increasingly widely used in the fields of organic waste resource utilization and insect protein production because its larvae can efficiently transform organic waste such as kitchen waste and livestock manure, while being rich in high-quality protein and fat.

[0003] The cultivation of black soldier flies typically involves three main stages: seedling raising (from egg hatching to early larvae), juvenile larvae (middle-aged larvae), and fattening (from old larvae to prepupae). The requirements for environmental temperature, material humidity, feed ratio, and stocking density vary at each stage.

[0004] In existing technologies, traditional black soldier fly farming equipment mostly adopts flat pond culture or single-layer tray culture. The three stages of seedling cultivation, juvenile larvae cultivation, and fattening need to be completed in different areas or different equipment. Each time the larvae are moved, the larvae need to be moved manually or mechanically. This not only results in high labor intensity and low efficiency, but also easily causes damage and stress to the larvae during the relocation process, affecting growth efficiency and survival rate. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, the present invention proposes a three-dimensional layered continuous feeding type full-cycle breeding equipment for horseflies, including a frame and at least six horizontally arranged belt conveyors. The at least six belt conveyors are installed on the frame and arranged at intervals in the vertical direction, and the distance between two adjacent belt conveyors is 200mm to 400mm.

[0006] The two adjacent belt conveyors are arranged alternately and staggered. The upper and lower layers have overlapping areas in the horizontal projection. The discharge end of the upper belt conveyor corresponds to the feed end of the lower belt conveyor, forming a zigzag material drop path.

[0007] To achieve the above objectives, at least six belt conveyors are vertically divided into at least one seedling layer at the top, one juvenile insect layer in the middle, and multiple fattening layers at the bottom, corresponding to different growth stages of the black soldier fly's entire breeding cycle. Each belt conveyor is configured to operate intermittently along its conveying direction to transport the breeding materials to the discharge end and then drop to the next layer, realizing the automatic flow of breeding materials layer by layer in the vertical direction. The entire process realizes fully automated continuous production from seedling to fattening and harvesting, eliminating the need for manual or mechanical relocation and avoiding insect damage and stress during relocation, thus significantly improving breeding efficiency and survival rate.

[0008] The net height between two adjacent belt conveyor layers is set to 200mm to 400mm. This height range ensures that hot air can flow naturally in the vertical direction, forming a stable vertical temperature gradient (higher temperature at the top and lower temperature at the bottom), while avoiding excessive overall equipment height or excessive gradient attenuation due to excessive layer height. The seedling layer is located at the top of the equipment, utilizing the higher temperature zone formed by rising hot air to meet the high-temperature environment requirements during the seedling stage. The fattening layer is located at the bottom of the equipment, utilizing the relatively cool zone formed by sinking cold air to neutralize the metabolic heat generated by material fermentation during the fattening stage and prevent local overheating. This design makes full use of the natural temperature distribution within the breeding environment, eliminating the need for additional complex temperature control systems or requiring only auxiliary temperature control to meet the temperature requirements at each stage, thus reducing energy consumption and equipment costs for breeding environment control.

[0009] Furthermore, a protective assembly is provided above the belt conveyor. The protective assembly includes four support rods, which are installed on the frame. The four support rods are arranged in a rectangular pattern to form a square frame structure. Lateral mesh belts are provided on both sides of the belt conveyor along the conveying direction. The bottom ends of the two lateral mesh belts are fixed to the corresponding support rods, and the top ends of the two lateral mesh belts are fixed to the frame. The two lateral mesh belts gradually slope outward from the bottom to the top, forming a flared structure that is narrow at the bottom and wide at the top.

[0010] Furthermore, the distance between the belt conveyor at the bottom layer and the belt conveyor above it is 400~700mm; the two lateral ends of the belt conveyor at the bottom layer extend to the two lateral ends of the frame, and a material distribution device is provided above the belt conveyor at the bottom layer.

[0011] Furthermore, the material distribution device includes a screen and an air-blocking membrane. The screen is positioned above the bottom belt conveyor, and the air-blocking membrane is positioned above the screen. The dimensions of both the air-blocking membrane and the screen are adapted to the bearing surface of the bottom belt conveyor.

[0012] Furthermore, the screen is a single-layer woven mesh structure with a mesh size of 4mm to 10mm.

[0013] Furthermore, rigid strip plates are fixedly provided at both ends of the screen and the air-barrier membrane along their conveying direction.

[0014] Furthermore, the four corner positions at the bottom of the frame are provided with support structures that cooperate with rigid strip plates.

[0015] Furthermore, the support structure includes a vertical plate fixed to the bottom of the frame, two vertical slide rails fixed along its height direction on the plate, and vertical sliders slidably connected to each vertical slide rail; two vertical sliders at the same height jointly support and are fixedly connected to a rod, the rod extending horizontally; there are four rods in total, the four rods are arranged at intervals in the vertical direction, respectively corresponding to the four corner positions of the screen and the air-blocking membrane, and each rod is fixedly provided with a protrusion; the plate is also provided with a power component for controlling the four rods to move closer or separate from each other.

[0016] Furthermore, the power assembly includes two lugs fixed to the bottom of the upright plate, with a transverse lead screw rotatably connected between the two lugs. A movable block threadedly connected to the lead screw is sleeved on the lead screw, and a movable plate is fixed on the movable block. The movable plate has guide grooves arranged at intervals, and protrusions on each support rod pass through the corresponding guide grooves and are slidably connected to the guide grooves. A transverse slide rail is also fixed on the upright plate, and a transverse slider is slidably connected on the transverse slide rail. The transverse slider is fixed to the movable plate. The support rods are, from top to bottom, a first support rod, a second support rod, a third support rod, and a fourth support rod. The rigid strip plate of the screen overlaps on the fourth support rod, and the rigid strip plate of the air-barrier membrane overlaps on the second support rod.

[0017] Furthermore, the thickness of the second and third support rods is 2mm to 5mm; the thickness of the rigid strip plate is 1mm to 3mm.

[0018] In summary, this three-dimensional, layered, continuous feeding system for the full-cycle aquaculture of soldier flies has the following beneficial effects:

[0019] (1) The three-dimensional layered continuous feeding type black soldier fly full-cycle breeding equipment has at least six belt conveyors that are vertically divided into at least one seedling layer at the top, one juvenile insect layer in the middle, and multiple fattening layers at the bottom, to correspond to different growth stages of black soldier fly full-cycle breeding. Each belt conveyor is configured to operate intermittently along its conveying direction to transport the breeding material on it to the discharge end and then fall to the next layer, realizing the automatic flow of breeding material layer by layer in the vertical direction. The whole process realizes full-cycle automated continuous production from seedling to fattening and harvesting, without the need for manual or mechanical transfer and handling, avoiding insect damage and stress response during the transfer process, and significantly improving breeding efficiency and survival rate.

[0020] (2) When black soldier flies grow to the prepupal stage, they have the biological characteristic of actively crawling out of the material to find a place to pupate. After the gas barrier film and screen cover the upper surface of the breeding material, a relatively closed, oxygen-deficient, and high-humidity environment is formed in the local area of ​​the material. Black soldier fly larvae are sensitive to the oxygen-deficient environment and will actively migrate to the surface or edge of the material in an attempt to find a more suitable environment. Black soldier flies will crawl out through the screen mesh and gather in the gap area between the screen and the film to achieve material distribution. Attached Figure Description

[0029] The technical solution of the present invention will be more clearly and completely explained below with reference to the accompanying drawings and through the description of preferred embodiments of the present invention.

[0030] like Figures 1-6 As shown, the preferred embodiment of the present invention provides a three-dimensional layered continuous feeding type full-cycle aquaculture equipment for horseflies, including a frame 1 and at least six horizontally arranged belt conveyors 2. The at least six belt conveyors 2 are installed on the frame 1 and arranged at intervals in the vertical direction, and the distance between two adjacent belt conveyors 2 is 200mm to 400mm.

[0031] The two adjacent belt conveyors 2 are arranged alternately and staggered. The upper and lower layers have overlapping areas in the horizontal projection. The discharge end of the upper belt conveyor 2 corresponds to the feed end of the lower belt conveyor 2, forming a zigzag material drop path.

[0032] At least six belt conveyors 2 are vertically divided into at least one seedling layer at the top, one juvenile insect layer in the middle, and multiple fattening layers at the bottom, corresponding to different growth stages of the entire black soldier fly breeding cycle. Each belt conveyor 2 is configured to operate intermittently along its conveying direction to transport the breeding materials on it to the discharge end and then fall to the next layer, realizing the automatic flow of breeding materials layer by layer in the vertical direction. The whole process realizes the full-cycle automated continuous production from seedling to fattening and harvesting, without the need for manual or mechanical relocation and handling, avoiding insect damage and stress during relocation, and significantly improving breeding efficiency and survival rate.

[0033] The net height between two adjacent belt conveyor layers 2 is set to 200mm to 400mm. This height range ensures that hot air can flow naturally in the vertical direction, forming a stable vertical temperature gradient with higher temperatures at the top and lower temperatures at the bottom. It also avoids excessive overall equipment height or excessive gradient attenuation due to excessive layer height. The seedling layer is located at the top of the equipment, utilizing the higher temperature zone created by rising hot air to meet the high-temperature environment requirements during the seedling stage. The fattening layer is located at the bottom of the equipment, utilizing the relatively cool zone created by sinking cold air to neutralize the metabolic heat generated by material fermentation during the fattening stage and prevent localized overheating. This design fully utilizes the natural temperature distribution within the aquaculture environment, eliminating the need for a complex additional temperature control system or requiring only auxiliary temperature control to meet the temperature requirements at each stage, thus reducing energy consumption and equipment costs for aquaculture environment control.

[0034] like Figure 6 As shown, a protective assembly is provided above the belt conveyor 2. The protective assembly includes four support rods 3, which are installed on the frame 1. The four support rods 3 are arranged in a rectangular shape to form a square frame structure. Lateral mesh belts 4 are provided on both sides of the belt conveyor 2 along the conveying direction. The bottom ends of the two lateral mesh belts 4 are fixed to the corresponding support rods 3, and the top ends of the two lateral mesh belts 4 are fixed to the frame 1. The two lateral mesh belts 4 gradually slope outward from the bottom to the top, forming a flared structure that is narrow at the bottom and wide at the top.

[0035] A square frame structure consisting of four support rods 3 is installed above the belt conveyor 2, and lateral mesh belts 4 are installed on both sides of the conveying direction. Since the lateral mesh belts 4 have a flared structure that is narrow at the bottom and wide at the top, when the aquaculture material falls from the discharge end of the upper mesh belt to the feed end of the lower mesh belt, the flared structure forms a gradually narrowing guide channel in the vertical direction, which can effectively constrain and guide the falling material, and prevent the material from splashing, scattering or deviating to the outside of the mesh belt due to airflow disturbance or falling deviation during the falling process between layers. This ensures that the material can fall accurately into the bearing area of ​​the lower mesh belt, maintain the continuity and stability of the material flow between layers, and the four support rods 3 do not interfere with the belt conveyor 2.

[0036] Black soldier fly larvae are highly mobile and have a tendency to climb upwards, making them prone to escaping along the side walls or edges of the rearing carrier during the rearing process. This equipment uses lateral mesh belts 4 installed on both sides of the conveying direction to form a physical barrier on both sides of the rearing area, effectively preventing larvae from escaping from the sides of the rearing carrier. At the same time, the structure of the lateral mesh belts 4, with the top fixed to the frame 1 and the bottom fixed to the support rods 3, ensures stable tension, maintaining the enclosure function for a long time and avoiding rearing losses caused by larvae crawling into gaps or climbing out.

[0037] The lateral mesh belt 4 adopts a mesh structure, which maintains good air permeability while providing enclosure. This design allows for air exchange in the lateral direction of the breeding area, forming a three-dimensional ventilation and heat dissipation system with the mesh structure of the belt conveyor 2 itself. This facilitates the timely removal of heat and moisture accumulated inside the material, reduces the risk of local heat accumulation and anaerobic fermentation, and provides a more suitable growth environment for black soldier fly larvae.

[0038] like Figure 2 As shown, the distance between the bottom belt conveyor 2 and the belt conveyor 2 above it is 400~700mm; the two ends of the bottom belt conveyor 2 extend to the two ends of the frame 1, and a material distribution device is provided above the bottom belt conveyor 2.

[0039] Black soldier fly larvae have the most vigorous metabolism during the pre-pupal stage in the later fattening period, when the heat generated by material fermentation reaches its peak. Poor heat dissipation can easily lead to excessively high local temperatures, affecting larval activity and even causing death. This equipment sets the net height between the bottom layer and the top layer to 400mm to 700mm, which is 200mm to 400mm greater than the spacing between the upper layers. The bottom layer is closer to the ground, and since the ground temperature is usually lower than the ambient temperature, and cold air naturally sinks, the bottom layer forms the lowest temperature area in the entire equipment. This precisely matches the temperature requirements in the later fattening period with the low-temperature environment of the bottom layer, effectively neutralizing the metabolic heat generated by material fermentation through passive heat dissipation. It can maintain a suitable growth temperature without the need for additional refrigeration equipment, further reducing breeding energy consumption and equipment costs.

[0040] The bottom-level belt conveyor 2 extends laterally to both ends of the frame 1, with a load-bearing length greater than that of the upper layers. This allows it to fully cover the projected area of ​​the upper layers, effectively catching all scattered materials and preventing them from falling into the gaps at the bottom of the equipment or outside the frame 1. A material separating device is integrated above the bottom-level belt conveyor 2 to separate the harvested materials into insect bodies and insect excrement. This integration of the material separating process with the breeding process within the same equipment achieves a fully integrated operation from the top seedling layer where organic waste is fed to the bottom material separating device where insect bodies and insect excrement are produced. There is no need to transport the harvested materials externally for separation. This not only simplifies the process and reduces the equipment footprint but also avoids damage to the insect bodies and secondary pollution during transportation.

[0041] like Figure 3 As shown, the material distribution device includes a screen 5 and an air-barrier membrane 6. The screen 5 is positioned above the bottom belt conveyor 2, and the air-barrier membrane 6 is positioned above the screen 5. The dimensions of both the air-barrier membrane 6 and the screen 5 are adapted to the bearing surface of the bottom belt conveyor 2. When black soldier flies reach the prepupal stage, they exhibit the biological characteristic of actively crawling out of the material to find a pupation site. After the air-barrier membrane 6 and the screen 5 cover the surface of the cultured material, a relatively closed, oxygen-deficient, and high-humidity environment is formed locally in the material. Black soldier fly larvae are sensitive to oxygen-deficient environments and will actively migrate to the surface or edge of the material, attempting to find a more suitable environment. The black soldier flies will crawl upward through the mesh of the screen 5 and gather in the gap area between the screen 5 and the membrane, thus achieving material distribution.

[0042] Screen 5 is a single-layer woven mesh structure with a mesh size of 4mm to 10mm. It allows black soldier fly larvae in the prepupal stage, with a body length of approximately 15-20mm and a body width of approximately 4-6mm, to pass through smoothly. The mesh size can be adjusted to accommodate different larval sizes.

[0043] Rigid strip plates 7 are fixedly installed at both ends of the screen 5 and the gas barrier membrane 6 along their conveying direction. The rigid strip plates 7 installed in front of and behind the screen 5 and the gas barrier membrane 6 provide reliable force points for the operator and facilitate the operator to remove the screen 5 and the gas barrier membrane 6.

[0044] The four corners at the bottom of the frame 1 are equipped with support structures that cooperate with the rigid strip plates 7. The support structures cooperate with the rigid strip plates 7 to support the screen 5 and the air-barrier membrane 6.

[0045] The support structure includes a vertical plate 8 fixed to the bottom of the frame 1. Two vertical slide rails 9 are fixed on the plate 8 along its height direction. Vertical sliders 10 are slidably connected to each vertical slide rail 9. The two vertical sliders 10 at the same height jointly support and are fixedly connected to a rod 11. The rod 11 extends horizontally. There are four rods 11 in total. The four rods 11 are arranged at intervals in the vertical direction, corresponding to the four corner positions of the screen 5 and the air-blocking membrane 6, respectively. Each rod 11 is fixedly provided with a protrusion 12. The plate 8 is also provided with a power component to control the four rods 11 to move closer or separate from each other.

[0046] The power assembly includes two lugs 13 fixed to the bottom of the upright plate 8. A transverse lead screw 14 is rotatably connected between the two lugs 13. A movable block threadedly connected to the lead screw 14 is sleeved on the lead screw 14. A movable plate 19 is fixed on the movable block. A guide groove 18 is spaced through the movable plate 19. The protrusions 12 on each support rod 11 pass through the corresponding guide groove 18 and are slidably connected to the guide groove 18. A transverse slide rail 16 is also fixed on the upright plate 8. A transverse slider 17 is slidably connected to the transverse slide rail 16. The transverse slider 17 is fixed to the movable plate 19. The support rods 11 are the first support rod 11, the second support rod 11, the third support rod 11, and the fourth support rod 11 from top to bottom. The rigid strip plate 7 of the screen 5 overlaps on the fourth support rod 11, and the rigid strip plate 7 of the air-barrier membrane cloth 6 overlaps on the second support rod 11.

[0047] By setting up a support structure consisting of a vertical slide rail 9, support rods 11, a power unit, and a guide groove 18, the automated clamping, positioning, and release of the screen 5 and the air-barrier membrane 6 are achieved. When the power unit drives the four support rods 11 to approach each other, the fourth support rod 11 and the screen 5 are moved to cover the bottom belt conveyor 2. The third support rod 11 and the first support rod 11 clamp the rigid strip plate 7 of the screen 5 and the rigid strip plate 7 of the air-barrier membrane 6, respectively. A motor 15 that drives the lead screw 14 to rotate is fixed on one of the lugs 13.

[0048] The thickness of the second and third support rods 11 is 2mm to 5mm; the thickness of the rigid strip plate 7 is 1mm to 3mm. The second and third support rods 11, with a thickness of 2mm to 5mm, have sufficient bending stiffness and match the thickness of the rigid strip plate 7. While clamping the rigid strip plate 7, they bring the screen 5 and the air-barrier membrane 6 closer together.

[0049] Before the equipment is started, each layer of belt conveyor 2 is in a stationary state. The operator turns on the motor 15, which drives the lead screw 14 to rotate. The rotation of the lead screw 14 will cause the moving block to move laterally, which in turn will cause the movable plate 19 fixed to the moving block to move. Through the cooperation of the wire groove and the protrusion 12, the movement of the movable plate 19 will cause the four support rods 11 to separate from each other. Then the screen 5 and the air-blocking membrane 6 are respectively attached to the fourth support rod 11 and the second support rod 11.

[0050] The prepared seedling feed and black soldier fly eggs or newly hatched larvae are evenly spread on the starting end of the belt conveyor 2 of the top seedling layer through the spreading mechanism. The top seedling layer is divided into 3-5 seedling sub-sections along the conveying direction, corresponding to a seedling cycle of 3-5 days. The equipment control system controls the belt conveyor 2 of the seedling layer to operate intermittently every day, with the operating distance being the length of the corresponding sub-section, so that the breeding materials are conveyed forward step by step. After the seedling cycle is completed in the seedling layer, the materials are moved to the discharge end with the belt and automatically fall to the second juvenile larvae layer through a zigzag dropping path.

[0051] At this stage, the seedling layer is located at the top of the equipment, utilizing a higher temperature zone of approximately 28°C-32°C formed by the natural rise of hot air, which meets the high-temperature environment required during the seedling stage, requiring no additional heating or only auxiliary heating.

[0052] After the seedling material falls to the starting end of the belt conveyor 2 of the juvenile worm layer, the juvenile worm layer is divided into 4-5 juvenile worm intervals along the conveying direction, corresponding to a juvenile worm breeding cycle of 4-5 days. The equipment control system controls the belt conveyor 2 of the juvenile worm layer to operate intermittently every day, so that the breeding material is conveyed forward step by step. After the juvenile worm breeding cycle is completed in the juvenile worm layer, the material is moved to the discharge end with the mesh belt and automatically falls to the first fattening layer below through the zigzag dropping path.

[0053] The juvenile larvae layer is located in the middle of the equipment, where the temperature is moderate, meeting the juvenile larvae's need for a moderate temperature during the juvenile stage.

[0054] After the material falls to the fattening layer, the multi-layer fattening layer of the equipment is usually arranged in 6-8 layers from top to bottom. Each layer is divided into multiple fattening sub-areas along the conveying direction, corresponding to a fattening cycle of 6-8 days. The equipment control system controls the belt conveyor 2 of each fattening layer to operate intermittently every day, so that the breeding material is conveyed forward step by step every day and falls to the next fattening layer at the end of the conveying.

[0055] The fattening layer forms a temperature gradient from top to bottom. The upper layer has a higher temperature, which is conducive to the rapid growth of larvae in the early stage. The lower layer has a lower temperature and is close to the ground. It takes advantage of the natural sinking of cold air to neutralize the large amount of metabolic heat generated by the fermentation of materials in the later stage of fattening and prevent local overheating. This design makes full use of the natural temperature distribution and does not require additional complex temperature control systems.

[0056] Throughout the breeding process, the flared structure of the lateral mesh belts above each layer, which is narrow at the bottom and wide at the top, guides the material as it falls, preventing it from splashing and larvae from escaping, while maintaining good air permeability.

[0057] When the material flows to the bottom fattening layer, the larvae have grown to the pre-pupa stage. The bottom belt conveyor 2 transports the breeding material to the distribution device area.

[0058] Then, the motor 15 is started, and the motor 15 drives the four support rods 11 to move closer to each other, so that the first support rod 11 and the second support rod 11 clamp the rigid strip plate 7 of the gas barrier membrane cloth 6, and the third support rod 11 and the fourth support rod 11 clamp the rigid strip plate 7 of the screen 5, realizing the automatic positioning and fixing of the screen 5 and the gas barrier membrane cloth 6. At this time, the screen 5 covers the bearing surface of the bottom belt conveyor 2, and the gas barrier membrane cloth 6 covers the screen 5. The gas barrier membrane cloth 6 and the screen 5 are not tensioned on the connected rigid strip plate 7, which makes it convenient for black soldier flies to enter between the gas barrier membrane cloth 6 and the screen 5, forming a locally sealed, oxygen-deficient, and high-humidity environment. Black soldier flies are sensitive to the oxygen-deficient environment and actively crawl out from the material, pass through the mesh of the screen 5 and enter the gap layer between the screen 5 and the gas barrier membrane cloth 6, and migrate along the surface of the screen 5 towards the edge or the discharge end.

[0059] After a preset time, once the migration is complete, the motor 15 moves the four support rods 11 away from each other, and the bottom belt conveyor 2, screen 5, and air-blocking membrane 6 separate and move away from each other. The black soldier fly is on the screen 5, achieving in-situ separation of the insect body and insect sand. The bottom belt conveyor 2 continues to operate, transporting the insect sand, insect excrement, and residual materials on the belt to the discharge end. After the air-blocking membrane 6 is pulled out, the screen 5 is then pulled out to obtain a high-purity insect body product, which can be used as a high-quality protein feed ingredient.

[0060] After cleaning or replacing the screen 5 and the air-blocking membrane 6, reattach the screen 5 and the air-blocking membrane 6 to the fourth support rod 11 and the second support rod 11, and drive the power assembly again to bring the four support rods 11 closer to each other to achieve automatic clamping and positioning, and then the working state can be restored.

[0061] The above-mentioned seedling raising, juvenile insect raising, fattening, and separation stages are carried out simultaneously within the equipment: new materials are continuously fed into the top layer, each layer operates on a daily schedule, and insect bodies and insect sand are continuously produced at the bottom layer. The entire process realizes fully automated continuous production from raw material input to final product output, without the need for manual transfer and handling or external separation equipment, fully demonstrating the integration, automation, and high efficiency of the equipment.
