Technical Field

[0001] This utility model relates to the field of organic waste conversion technology, specifically to a three-dimensional biomimetic conversion system for insect-derived organic waste. Background Technology

[0002] Insects such as mealworms and black soldier flies have advantages such as short conversion cycles, efficient nutrient absorption, and low greenhouse gas emissions, and are widely used in the production of insect protein from kitchen waste and livestock manure. Chinese invention patent application CN108575914A discloses a device and method for converting agricultural organic waste using insects. It uses a longitudinal transport pipe and a feeding pipe above each conversion tank to feed the waste into each tank. However, in years of practical use, the applicant has found the following drawbacks: the feeding pipe above each conversion tank, connected to a second conveyor via a T-joint, is complex, difficult to maintain, and prone to clogging, hindering technology promotion. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a three-dimensional biomimetic conversion system for insect organic waste. This system enables multi-layer material feeding, conversion, and turning, expanding insect farming from a flat pond farming model to a three-dimensional shelf farming model. It simplifies the process and equipment, automates the entire farming process, and achieves high efficiency and low farming costs.

[0004] To address the aforementioned technical problems, this utility model provides a three-dimensional biomimetic conversion system for insect-derived organic waste, comprising:

[0005] A multi-layer conversion rack, the multi-layer conversion rack including multiple conversion boxes, the multiple conversion boxes being arranged at intervals along the height direction of the multi-layer conversion rack;

[0006] A multi-layer feeder includes a lifting mechanism, a discharge bin, a feeding mechanism, and multiple receiving mechanisms. The discharge bin is arranged between the lifting mechanism and the feeding mechanism. The lifting mechanism is used to lift the material to the top of the discharge bin. The feeding mechanism includes multiple feeding conveyors, which are arranged correspondingly to multiple conversion boxes for feeding material into each conversion box. A discharge port is opened on the side of the discharge bin near the feeding mechanism. The receiving mechanisms are arranged at the discharge port, and the multiple receiving mechanisms are arranged correspondingly to the multiple feeding conveyors for receiving material onto the corresponding feeding conveyor.

[0007] The material turning mechanism is used to flip the multi-layer conversion rack to pour out the insects and materials in the multi-layer conversion rack.

[0008] In some embodiments, the receiving mechanism includes a receiving drive mechanism and a receiving plate. The receiving plate is provided with a receiving position and a clearance position. The receiving drive mechanism is used to control the receiving plate to move to the receiving position to receive the material falling from the hopper to the feeding conveyor, or to control the receiving plate to move to the clearance position to avoid the material falling from the hopper.

[0009] In some embodiments, the receiving drive mechanism is installed on the discharge bin or the feeding mechanism. One end of the receiving plate is provided with a rotating shaft, which is arranged close to the feeding conveyor. The receiving drive mechanism controls the rotation of the receiving plate through the rotating shaft, so that the other end of the receiving plate turns into the discharge bin to receive the material.

[0010] In some embodiments, the height of the discharge port is equal to the sum of the lengths of the plurality of receiving plates, such that the discharge port can be closed when the plurality of receiving plates rotate to the clearance position.

[0011] In some embodiments, the multi-layer conversion frame is arranged on a track parallel to the conveying direction of the feeding conveyor. The multi-layer conversion frame is connected to a push-pull mechanism, which controls the multi-layer conversion frame to move closer to or further away from the feeding conveyor, so that the material on the feeding conveyor falls evenly onto the conversion box.

[0012] In some embodiments, the conversion box includes multiple sides and a bottom surface, one of which is arranged at an angle and is used for material discharge, while the other sides are arranged vertically. The bottom surface and the vertically arranged sides provide a breathable, water-permeable, heat-permeable, and light-proof natural environment similar to that of insects. Both the bottom surface and the vertically arranged sides include plastic plates with holes, and support nets are provided on the holes.

[0013] Furthermore, the flipping mechanism includes a flipping base, a flipping frame rotatably mounted on the flipping base, an installation position on the flipping frame, the multi-layer conversion frame being fixed at the installation position, and a flipping drive mechanism on the flipping base for driving the flipping frame to rotate, thereby flipping the multi-layer conversion frame at the installation position.

[0014] Furthermore, it includes an insect-feed separation device, which separates insects by suffocating them or by mechanical separation using a vibrating screen.

[0015] In some embodiments, the insect-material separation device includes a flexible cover for completely covering the insects and materials. The edge of the cover is provided with a seal to seal the edge of the cover to the ground to prevent or reduce air entry. A separation chamber is provided inside the cover, and multiple separation holes are opened at the bottom of the separation chamber so that insects can enter the separation chamber through the separation holes to achieve insect-material separation.

[0016] In some embodiments, the cover includes an upper cover and a lower cover, with a support member disposed between the upper cover and the lower cover. The support member supports the upper cover and the lower cover apart, thereby forming the separation cavity between the upper cover and the lower cover, and the separation hole is formed on the lower cover.

[0017] In some embodiments, the support includes a pipe, one end of which extends out of a cover and is connected to a vacuum pump.

[0018] On the other hand, this utility model provides a conversion process based on a three-dimensional biomimetic conversion system for insect organic waste, including: a mixer stirring the material; the stirred material being conveyed to a multi-layer feeder, which conveys the material to each conversion box of the multi-layer conversion rack; after conversion, the multi-layer conversion rack being transferred to a turning mechanism, which pours out all the material and insects from the conversion boxes; and an insect-material separation device separating the poured-out material and insects.

[0019] In some embodiments, the method by which a multi-layer feeder delivers material to the individual conversion boxes of a multi-layer conversion rack includes:

[0020] The lifting mechanism continuously lifts the material to the top of the discharge hopper. The feeding controller controls a receiving drive mechanism, causing the corresponding receiving plate of the receiving drive mechanism to rotate to the receiving position. The receiving plates above the corresponding receiving plate of the receiving drive mechanism are all in the clearance position. The feeding conveyor transports the material to the corresponding conversion box. The push-pull mechanism controls the multi-layer conversion frame to move closer to or away from the feeding conveyor, so that the material on the feeding conveyor falls evenly onto the conversion box, completing the feeding of that layer of conversion box. The above steps are repeated until all conversion boxes are fed.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. The multi-layer conversion rack and multi-layer feeder of this utility model are designed with a multi-layer three-dimensional process, realizing multi-layer material feeding, conversion and turning, expanding insect farming from a flat pond farming mode to a three-dimensional farming mode. Compared with the flat pond farming mode, the three-dimensional farming mode saves space, is conducive to deodorization treatment, the equipment functions and processes are simple, realizes full automation of the farming process, has high efficiency, low cost, and can be scaled up, factory-scaled, clean and environmentally friendly.

[0023] 2. The material receiving drive mechanism of this utility model drives the material receiving plate to rotate through a rotating shaft, thereby realizing the material receiving plate receiving or avoiding material; in addition, the material receiving plate can also be received or avoided by translation.

[0024] 3. The height of the discharge port of this utility model is equal to the sum of the lengths of multiple receiving plates. When the multiple receiving plates rotate to the clearance position, they can close the discharge port. When one of the receiving plates rotates to the receiving position, it can prevent the material from spilling out from the discharge port corresponding to other receiving plates.

[0025] 4. The bottom and some sides of the conversion box of this utility model are designed to be permeable to water and air, which increases the oxygen content of the material, avoids anaerobic fermentation, reduces the emission of methane and carbon dioxide in the anaerobic process, and the increased oxygen content of the material is conducive to improving the vitality of insects and probiotics, resulting in increased biomass and conversion efficiency.

[0026] 5. This utility model achieves uniform spreading of materials in the conversion box by setting up a track and a push-pull mechanism.

[0027] 6. The insect-feed separation device of this utility model uses the method of suffocating insects to separate insects, which helps to improve the separation efficiency. Attached Figure Description

[0052] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0053] This utility model provides a three-dimensional biomimetic conversion system for insect organic waste, including a screw conveyor, a mixer, a multi-layer conversion frame 1, a multi-layer feeder 2, a transfer device, a turning mechanism 3, and an insect-material separation device 4.

[0054] The auger conveyor is connected to the mixer to transport materials (i.e., organic waste) to the mixer, which is used to mix and pre-treat the materials.

[0055] like Figure 2 As shown, the multi-layer conversion rack 1 includes a frame, on which multiple conversion boxes 11 are fixed, and the multiple conversion boxes 11 are arranged at intervals along the height direction of the multi-layer conversion rack 1.

[0056] In some embodiments, such as Figure 5 As shown, the frame may include four uprights 12, and the conversion box 11 can be fixed to the uprights 12 by bolts, as shown. Figure 6 As shown, a support plate 15 is fixedly installed on the frame by bolts, and a support foot is installed on the conversion box 11. The support foot is placed on the support plate 15 and is fixedly connected to the column 12 by bolts.

[0057] In some embodiments, such as Figure 2 As shown, the multi-layer conversion rack 1 can also be modularly configured. The multi-layer conversion rack 1 includes multiple columns 12, such as... Figure 3 As shown, the conversion box 11 has multiple connection ports 111 on both sides. A limiting plate is fixedly installed in the middle of the connection port 111. The upper end of the column 12 can be inserted into the lower end of the connection port 111 and abut against the limiting plate. The lower end of the column 12 can be inserted into the upper end of the connection port 111 and abut against the limiting plate. The column 12 and the connection port 111 are fixed together by a mortise and tenon structure, thus forming a multi-layer conversion box 11 structure. The base 14 has a socket that mates with the column 12, so that the column 12 can be fixed on the base 14. The base 14 is made of stainless steel.

[0058] In addition, threaded connections can also be used, such as... Figure 4As shown, an internal thread connector 121 and an external thread connector 122 are respectively provided at both ends of the column 12. The inner wall of the internal thread connector 121 is provided with an internal thread, and the outer wall of the external thread connector 122 is provided with an external thread. The two columns 12 can be threadedly connected by the internal thread connector 121 and the external thread connector 122. That is, the column 12 inserted from above the connection port 111 and the column 12 inserted from below the connection port 111 can be threadedly connected, and the column end faces 123 of the two columns 12 abut against the two ends of the connection port 111.

[0059] like Figure 3 As shown, the conversion box 11 includes a bottom surface and four sides. Three of the sides are perpendicular to the bottom surface, and the fourth side forms an obtuse angle (e.g., 135°) with the bottom surface, facilitating the pouring of materials out of the conversion box 11. The bottom surface and the sides perpendicular to the bottom surface of the conversion box 11 are both permeable to water and air. The side forming the obtuse angle with the bottom surface consists only of a plastic sheet, ensuring smooth material discharge. Both the bottom surface and the sides perpendicular to the bottom surface of the conversion box 11 include a plastic sheet with holes. These holes can be circular, square, or rectangular, and a support mesh 13 is installed on the holes. The support mesh 13 can be made of stainless steel wire mesh or polyester mesh belt, and it is integrated with the plastic sheet during molding. The support net 13 is breathable, water-permeable, and heat-permeable, while the plastic board provides shade, creating a simulated natural environment similar to that of insects. This increases the oxygen content of the material, avoids anaerobic fermentation, and reduces methane and carbon dioxide emissions during the anaerobic process. The increased oxygen content of the material is beneficial for enhancing the vitality of insects and probiotics, resulting in increased biomass and improved conversion efficiency.

[0060] Furthermore, the tops of the three sides perpendicular to the bottom surface are provided with inward-facing baffles, which are parallel to the bottom surface. These baffles are used to prevent insects from crawling out of the conversion box 11 when the temperature and humidity are unsuitable.

[0061] like Figure 7 As shown, the multi-layer feeder 2 includes a feeding frame 24, a lifting mechanism 23, a discharge bin 25, a feeding mechanism 26, and multiple receiving mechanisms. The lifting mechanism 23, discharge bin 25, and feeding mechanism 26 are all mounted on the feeding frame 24. The discharge bin 25 is positioned between the lifting mechanism 23 and the feeding mechanism 26. The lifting mechanism 23 lifts the material to the top of the discharge bin 25, and the multiple receiving mechanisms guide the material onto the feeding mechanism 26. Both the lifting mechanism 23 and the feeding mechanism 26 utilize belt conveyors. The lifting mechanism 23, feeding mechanism 26, and receiving mechanisms are all controlled by a feeding controller.

[0062] like Figure 7 As shown, the right end of the lifting mechanism 23 is fixed to the lifting block 21, and a barrier 22 is provided on the right end of the lifting mechanism 23. The barrier 22 can block the material falling into the lifting mechanism 23 and prevent it from falling.

[0063] like Figure 9 , 10 As shown, the top of the material discharge bin 25 is flared, and the top of the material discharge bin 25 is connected to the left end of the lifting mechanism 23. The material discharge bin 25 has a discharge port 251 on the side near the feeding mechanism 26. The discharge port 251 extends from the position of the material discharge bin 25 near the flared structure to the bottom of the material discharge bin 25.

[0064] like Figure 8 As shown, the feeding mechanism 26 includes multiple feeding conveyors 261, which are arranged correspondingly to multiple conversion boxes 11 for feeding materials into each conversion box 11. A receiving mechanism is arranged at the discharge port 251, with multiple receiving mechanisms corresponding to the multiple feeding conveyors 261. The receiving mechanism includes a receiving drive mechanism and a receiving plate 27. The receiving plate 27 has a receiving position and a clearance position. The receiving drive mechanism controls the receiving plate 27 to move to the receiving position to receive materials falling from the discharge bin 25 to the feeding conveyors 261, or controls the receiving plate 27 to move to the clearance position to avoid materials falling from the discharge bin 25.

[0065] like Figure 8 As shown, the top receiving plate 27 is in the clearance position, while the other receiving plates 27 are in the receiving position. The material can fall onto the second layer (from top to bottom) feeding conveyor 261 through the second receiving plate 27, thereby conveying the material to the corresponding conversion box 11. When it is necessary to feed other conversion boxes 11, the corresponding receiving plate 27 can be controlled to move to the receiving position, and the receiving plate 27 above it can move to the clearance position, thus realizing the feeding of the corresponding conversion box 11. This utility model realizes the feeding of multiple conversion boxes 11, and the feeding structure is simple and easy to maintain.

[0066] In some embodiments, the receiving drive mechanism can be installed on the feeding rack 24, the dropping bin 25, or the feeding mechanism 26. One end of the receiving plate 27 is provided with a rotating shaft, which is arranged close to the feeding conveyor 261. The receiving drive mechanism controls the rotation of the receiving plate 27 through the rotating shaft, so that the other end of the receiving plate 27 turns into the dropping bin 25 to receive the material. Figure 8 The material receiving drive mechanism is not shown in the figure. The material receiving drive mechanism can be a geared motor. The geared motor is bolted to the feeding frame 24. The output end of the geared motor is connected to one end of the rotating shaft. The rotating shaft is arranged at the discharge port 251 of the discharge bin 25. The other end of the rotating shaft can be rotatably connected to the discharge bin 25. The rotation of the receiving plate 27 can be controlled by the geared motor. When the receiving plate 27 rotates to the vertical direction, the receiving plate 27 is in the clearance position. When the receiving plate 27 rotates to the point where one end abuts against the inner wall of the discharge bin 25, the receiving plate 27 is in the receiving position.

[0067] In addition, in some embodiments, the receiving plate 27 can also receive or avoid materials through linear movement. For example, the receiving plate 27 is arranged at an angle, and the receiving drive mechanism controls the receiving plate 27 to move horizontally into the discharge bin 25 until the upper end of the receiving plate 27 abuts against the inner wall of the discharge bin 25. At this time, the receiving plate 27 is in the receiving position. The receiving drive mechanism then controls the receiving plate 27 to move horizontally outside the discharge bin 25 until the upper end of the receiving plate 27 is flush with the discharge port 251 of the discharge bin 25. At this time, the receiving plate 27 is in the avoiding position. The receiving drive mechanism can be a cylinder, which can also be mounted on the feeding rack 24. The cylinder can be connected to the receiving plate 27 through an L-shaped connecting rod. The connecting rod is arranged on the side of the discharge bin 25 near the feeding mechanism 26. One end of the connecting rod is connected to the cylinder, and the other end of the connecting rod is connected to the center of the receiving plate 27, thereby controlling the horizontal movement of the receiving plate 27. However, in this scheme, the material will fall onto the connecting rod.

[0068] In some embodiments, the height of the discharge port 251 is equal to the sum of the lengths of the plurality of receiving plates 27, such that the discharge port 251 can be closed when the plurality of receiving plates 27 are rotated to the clearance position.

[0069] like Figure 8 As shown, when the receiving plate 27 rotates to the clearance position, it can connect with the receiving plate 27 above it, thereby achieving the closure of the discharge port 251. The closure of the discharge port 251 does not need to be completely sealed; it is only necessary to ensure that most of the material falling into the discharge bin 25 will not splash out of the discharge bin 25. In addition, a sealing colloid can be provided on the edge of the receiving plate 27. The receiving plate 27 contacts the inner wall of the discharge bin 25 and the adjacent receiving plate 27 through the sealing colloid, thereby improving the sealing performance.

[0070] In some embodiments, such as Figure 11 As shown, the multi-layer conversion frame 1 is arranged on the track 5, which is parallel to the conveying direction of the feeding conveyor 261. The multi-layer conversion frame 1 is connected to a push-pull mechanism, which is used to control the multi-layer conversion frame 1 to move closer to or further away from the feeding conveyor 261, so that the material on the feeding conveyor 261 falls evenly onto the conversion box 11.

[0071] Understandable, Figure 7 In the state shown, the material can only be conveyed to one end of the conversion box 11 and accumulate. Therefore, it is necessary to move the conversion box 11 during the conveying process so that the material falls evenly into the conversion box 11. By setting the track 5 and the push-pull mechanism, the material in the conversion box 11 can be evenly spread.

[0072] like Figure 11As shown, a placement platform 6 is set on the track 5, and rollers 61 are set at the bottom of the placement platform 6, allowing the placement platform 6 to move on the track 5. The two sides of the rollers 61 are locked onto the two sides of the track 5, making it difficult for the rollers 61 to derail. The multi-layer conversion frame 1 can be installed on the placement platform 6. The multi-layer conversion frame 1 and the placement platform 6 can be fixedly connected by bolts or snap-fit. For example, the bottom of the multi-layer conversion frame 1 is integrally set with a connecting plate, and bolt holes are opened on the placement platform 6. The multi-layer conversion frame 1 can be fixed by fixing the connecting plate to the placement platform 6; or the bottom side of the multi-layer conversion frame 1 is opened with fixing holes, and multiple locking holes are opened on the placement platform 6. The side of the placement platform 6 is equipped with elastic locking pins. After the bottom of the multi-layer conversion frame 1 is inserted into the locking holes, one end of the elastic locking pin extends into the locking holes and is inserted into the fixing holes of the multi-layer conversion frame 1, thereby fixing the multi-layer conversion frame 1. When it is necessary to remove the multi-layer conversion frame 1, the elastic locking pin is pulled, so that one end of the elastic locking pin is pulled out from the fixing holes of the multi-layer conversion frame 1.

[0073] The push-pull mechanism can use the principle of gear and rack to control the movement of the placement platform 6. For example, the push-pull mechanism includes a geared motor, which is arranged below the placement platform 6. The output end of the geared motor is fixedly connected to a gear. A rack is set at the bottom of the placement platform 6. The rack meshes with the gear to generate linear displacement. The movement should be slow to ensure the smooth movement of the multi-layer conversion frame 1.

[0074] like Figure 12 As shown, the flipping mechanism 3 includes a flipping base 31, a flipping frame 32 rotatably mounted on the flipping base 31, and a mounting position on the flipping frame 32. The multi-layer conversion frame 1 can be fixed in the mounting position. A flipping drive mechanism 33 is provided on the flipping base 31. The flipping drive mechanism 33 is used to drive the flipping frame 32 to rotate, thereby flipping the multi-layer conversion frame 1 in the mounting position. Figure 15 As shown, by setting up the material turning mechanism 3, all the materials and insects in all the conversion boxes 11 on the entire multi-layer conversion rack 1 can be poured out at the same time, which improves work efficiency.

[0075] like Figure 14 As shown, a rotating bearing 311 is provided on the top of the tilting base 31, and the tilting frame 32 is rotatably connected to the tilting base 31 via the rotating bearing 311, as shown. Figure 13 As shown, the flipping drive mechanism 33 is installed on the outer side of the flipping base 31, and the flipping drive structure can be a geared motor.

[0076] like Figure 12As shown, multiple crossbeams 321 are arranged on the left and right sides of the flipping frame 32. Locking devices 323 are installed on the crossbeams 321. After the multi-layer conversion frame 1 is transported onto the flipping frame 32, it can be locked by the locking devices 323, allowing the multi-layer conversion frame 1 to rotate together with the flipping frame 32. The locking device 323 can be an electromagnetic lock, with a corresponding magnet fixed on the multi-layer conversion frame 1, thus fixing the multi-layer conversion frame 1 by magnetic force; alternatively, the locking device 323 can be an electric telescopic shaft, with corresponding locking holes on the multi-layer conversion frame 1, and one end of the electric telescopic shaft can extend into the locking hole to fix the multi-layer conversion frame 1.

[0077] like Figure 12 As shown, multiple limiting beams 322 are provided on the front side of the flipping rack 32. After the multi-layer conversion rack 1 is transported to the flipping rack 32, it is placed against the limiting beams 322, so that the magnet on the multi-layer conversion rack 1 is just in contact with the electromagnetic lock. At this time, the electromagnetic lock can be opened to fix the multi-layer conversion rack 1.

[0078] The insect-feed separation device 4 separates insects by either suffocating them or by using a mechanical separation method of vibrating screen.

[0079] In some embodiments, the insect-feed separation device 4 separates the insects by suffocating them. For example... Figure 16 , 17 As shown, the insect-material separation device 4 includes a flexible cover 41, which is used to completely cover the insects and materials. The edge of the cover 41 is provided with a sealing element 43, which is a flexible structure, such as a flexible rubber sealing strip. The sealing element 43 is used to seal the edge of the cover 41 with the ground to prevent or reduce the entry of air. A separation chamber 44 is provided inside the cover 41. Multiple separation holes 45 are opened at the bottom of the separation chamber 44, so that insects can enter the separation chamber 44 through the separation holes 45, thereby realizing the separation of insects and materials.

[0080] Understandably, by using a flexible cover 41 to completely cover the insects and materials, and using a sealing element 43 to seal the edges of the cover 41 to the ground, the oxygen in the materials gradually decreases, forcing the insects to crawl out of the materials and enter the separation chamber 44 through the separation hole 45, thereby separating the insects from the materials. Because the cover 41 is flexible, it is applicable to materials of different thicknesses, and for insects and materials laid directly on the ground or soil, simply spreading the cover 41 on the materials achieves effective and efficient separation of the insects.

[0081] like Figure 18As shown, the cover 41 includes an upper cover 411 and a lower cover 412. Both the upper cover 411 and the lower cover 412 have the same rectangular structure, and each includes a long side and a short side. The size of the upper cover 411 is greater than or equal to that of the lower cover 412. The upper cover 411 is made of an opaque material, such as a black and white film, a black film, or a rainproof cloth. Figure 19 As shown, the lower cover 412 is provided with multiple separation holes 456. The lower cover 412 can be made of a mesh or other structure, and the diameter of the separation holes 456 is 3-7mm. The edges of the upper cover 411 and the lower cover 412 are only partially connected or not connected. The unconnected edges of the upper cover 411 and the lower cover 412 are set as discharge outlets, so that insects entering the separation chamber can be discharged from the discharge outlets.

[0082] A support member 42 is provided between the upper cover 411 and the lower cover 412. The support member 42 can be made of low-density materials such as foam, and its upper surface can be fixed to the upper cover 411 with adhesive. Alternatively, the support member 42 can be a pipe with a suction hole near the top. One end of the support member 42 extends out of the cover 41 and is connected to an air pump. The air pump can quickly expel the air within the coverage area of ​​the cover 41, accelerating the reduction of oxygen within the coverage area and saving separation time.

[0083] like Figure 1 As shown, based on the above-mentioned three-dimensional biomimetic transformation system for insect organic waste, this utility model provides a three-dimensional biomimetic transformation process for insect organic waste, including:

[0084] S1. Material Pretreatment: The material is conveyed to the mixer using a auger conveyor and then stirred. Pretreatment comprehensively processes the material's carbon-nitrogen ratio, temperature, humidity, physical state, and microbial inoculants. Suitable for the resource utilization of insects such as fly larvae, mealworms, black soldier flies, bamboo worms, breadworms, feed insects, protein worms, and superworms.

[0085] S2. Feeding: The mixed material is conveyed to the multi-layer feeder 2. Insect seedlings are added simultaneously when the material is conveyed to the multi-layer feeder 2. The multi-layer feeder 2 conveys the material to each conversion box 11 of the multi-layer conversion rack 1; specifically including:

[0086] The lifting mechanism 23 continuously lifts the material to the top of the discharge bin 25. The feeding controller controls a receiving drive mechanism, causing the receiving plate 27 corresponding to the receiving drive mechanism to rotate to the receiving position. The receiving plates 27 above the receiving plate 27 corresponding to the receiving drive mechanism are all in the clearance position. The feeding conveyor 261 conveys the material to the corresponding conversion box 11. The push-pull mechanism controls the multi-layer conversion frame 1 to move closer to or away from the feeding conveyor 261, so that the material on the feeding conveyor 261 falls evenly onto the conversion box 11, completing the feeding of the conversion box 11. The above steps are repeated until the feeding of all conversion boxes 11 is completed.

[0087] It should be noted that material should generally be added starting from the lowest conversion box 11 to avoid raising the center of gravity of the bogie and affecting its stability.

[0088] Furthermore, the push-pull mechanism can be controlled by a feeding controller, and the multi-layer feeder 2 can also automatically control the feeding time and quantity through the feeding controller. Since the conveying speeds of the lifting mechanism 23 and the feeding conveyor 261 are known, the feeding time for each conversion box 11, i.e., the time T0 for each receiving plate 27 to be in the receiving position, can be calculated based on the conveying speed and the amount of material to be added. Specifically:

[0089] Initially, all receiving plates 27 are in the clearance position. Material is first added to the lowest conversion box 11. The feeding controller activates the lifting device, feeding conveyor 261, and push-pull mechanism, allowing the material to fall directly to the bottom of the discharge bin 25 and slide onto the lowest feeding conveyor 261. The feeding conveyor 261 then transports the material into the lowest conversion box 11. Under the action of the push-pull mechanism, the multi-layer conversion frame 1 ensures the material falls evenly onto the conversion box 11. After time T0, the feeding controller activates the receiving drive corresponding to the second layer (from bottom to top) feeding conveyor 261. The moving mechanism rotates the receiving plate 27 to the receiving position, and the material falls onto the receiving plate 27. It is then conveyed to the conversion box 11 of the second layer (from bottom to top) by the feeding conveyor 261 of the second layer. After time T0, the feeding controller controls the receiving drive mechanism corresponding to the feeding conveyor 261 of the third layer (from bottom to top) to rotate the receiving plate 27 to the receiving position to feed the conversion box 11 of the third layer (from bottom to top). This process is repeated until all conversion boxes 11 are fed. The feeding controller then controls the lifting device, feeding conveyor 261, and push-pull mechanism to close.

[0090] S3, Transformation.

[0091] S4. After the conversion is completed, the multi-layer conversion rack 1 is transferred to the material handling mechanism 3; the transfer of the multi-layer conversion rack 1 can be carried out by an unmanned forklift.

[0092] S5. The turning mechanism 3 pours out all the materials and insects in the conversion box 11. A conveyor belt can be installed below the turning mechanism 3 to transport the materials and insects to the corresponding position of the insect-material separation process.

[0093] S6, the insect-feed separation device 4 separates the poured-out material and insects, specifically including:

[0094] S61, such as Figure 17 As shown, a covering 41 is laid on the flat material, and the edge of the covering 41 is sealed by a sealing member 43; wherein, the material and insects are laid flat on a hardened ground or field, the thickness of the flat laying is controlled to be 5~50cm, and the ambient temperature is controlled to be 10-50℃.

[0095] S62. After standing for a period of time, lift the cover and remove the insect that has entered the separation chamber 44.

[0096] Understandably, since the seal 43 is flexible, it can prevent or reduce the entry of outside air on hardened ground and soil with uneven surfaces. The oxygen in the material is gradually consumed by the insects, while the oxygen concentration in the separation chamber 44 is high, which will force the insects to crawl out and enter the separation chamber 44 through the separation hole 45. Since the upper cover 411 is opaque, it can avoid the separation effect from deteriorating due to the photophobia of some insects. After standing for 3-15 minutes, the insects can be shaken off from the outlet to the collection area.

[0097] If the support member 42 is a hollow tube, an air pump is used to exhaust the air in the covered area of ​​the cover member 41 through the hollow tube. The oxygen concentration near the hollow tube is higher than that in other areas, which causes insects to crawl out of the material and enter the separation chamber 44 through the separation hole 45 and approach the hollow tube. The air pump only needs to pump air for a short time, such as 5 seconds, so that an oxygen-deficient environment is formed in the covered area of ​​the cover member.

[0098] This insect-material separation device 4 is mainly used for insects and materials spread over a large area on hardened ground or soil. A flexible covering 41 of the corresponding size is directly applied, and the insects can be separated manually in one go, achieving a separation rate of over 99%. This insect-material separation device 4 is simple to manufacture, inexpensive, and highly efficient.

[0099] To achieve a low-cost conversion process, the applicant developed a conversion system that simultaneously realizes multi-layer material feeding, conversion, and turning. This invention, through a multi-layer, three-dimensional process design, expands insect farming from a flat pond farming model to a three-dimensional farming model. Compared to the flat pond farming model, the three-dimensional farming model saves space, facilitates deodorization, has simple equipment functions and processes, automates the entire farming process, is highly efficient, has low farming costs, and allows for large-scale, factory-style, clean, and environmentally friendly farming, which is conducive to industrial promotion.

[0100] This invention features a reasonable structure, convenient operation, small footprint, and low labor requirements, making it particularly suitable for large-scale factory farming. The resource utilization of organic waste and the elimination of livestock manure pollution are of great significance for protecting the ecological environment and promoting sustainable agricultural development.
