Description

Technical Field

[0001] This utility model relates to an automated device for raising or pupating insect larvae, belonging to the category of insect farming equipment. Background Technology

[0002] Insect farming boasts advantages such as low cost, small space requirements, and rapid reproduction. Insects are rich in protein and other nutrients, serving as high-quality feed and also processing organic waste, reducing environmental pollution. Furthermore, insects are diverse in species, have wide applications, promising prospects, and high economic value, making them significant for agricultural development and ecological protection. Holometabolous insects undergo four stages: egg, larva, pupa, and adult, with significant differences in morphology and habits between larvae and adults. In the larval stage of some insects, timely sieving of insect excrement is crucial to prevent its accumulation, which releases ammonia, increases humidity, and breeds mold and mites, leading to larval death. It also prevents excrement from contaminating feeds like wheat bran, reducing palatability and conversion rates. Timely sieving reduces waste; separating the excrement creates a cleaner environment for the insects, reducing stress and accelerating molting and weight gain. Therefore, timely sieving of insect excrement is essential for the farming of mealworms and breadworms. Currently, most insect farming methods employ pond, box, or cage rearing, requiring manual sieving and box separation, resulting in low efficiency and high labor costs.

[0003] After pupation, larvae need to be separated into pupae promptly to prevent them from becoming immobile and defenseless, making them vulnerable to being eaten by un-pupiled larvae or adults, resulting in losses. Separation also prevents pupae from developing at different stages within the same box. After separation, pupae can be grouped in batches with controlled temperature and humidity to achieve synchronized emergence, facilitating subsequent egg-laying arrangements. Currently, most pupation separation operations rely on manual sieving and box-separation, which is inefficient and costly in terms of labor.

[0004] Therefore, it is of great significance to develop an automated device for larval rearing and pupation. Utility Model Content

[0005] This invention provides an automated device for raising or pupating insect larvae, which solves the problems of low efficiency and high labor costs associated with manual screening and boxing operations in existing larval raising or pupation processes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An automated insect larvae rearing or larvae pupation device includes several belt conveyors, with a square frame mounted on top of each belt conveyor. An isolation door is mounted at one or both ends of each square frame. The belt conveyors and the square frame enclose a rearing space. A screening mechanism is provided between every two belt conveyors. When the device is used for larval rearing, the area of ​​several rearing spaces increases progressively. The feed inlet of the screening mechanism is connected to the discharge end of the belt conveyor mentioned earlier, and the larval outlet of the screening mechanism is connected to the feed inlet of the belt conveyor mentioned later. When the device is used for larval pupation, the area of ​​the breeding space of several belt conveyors gradually decreases. The feed inlet of the screening mechanism is connected to the discharge end of the belt conveyor mentioned above, and the larval outlet of the single-layer screening mechanism is connected to the feed inlet of the belt conveyor mentioned below.

[0007] Furthermore, preferably, the number of belt conveyors in each stage is allowed to vary.

[0008] Furthermore, preferably: the square frame includes two side panels and isolation doors on both sides of the side panels, and the side panels include a vertical part and an elastic arc-shaped part installed together in sequence.

[0009] Furthermore, preferably: the square frame includes two side panels and isolation doors on both sides of the side panels, the side panels include an upper frame, a ventilation panel, a lower frame and an elastic arc-shaped part installed together in sequence, and the ventilation panel is provided with air holes.

[0010] Furthermore, preferably, the ventilation panel is provided with a ventilation duct on its exterior.

[0011] Furthermore, preferably: the larval rearing or larval pupation device further includes an atomizing mechanism and a layered control system, wherein the automatic rearing and conveying mechanism, the screening mechanism and the atomizing mechanism are respectively connected to the layered control system.

[0012] Furthermore, preferably, the larval rearing or larval pupation device further includes at least one of a temperature and humidity sensor, a video image acquisition device, and an observation port, wherein the temperature and humidity sensor and the video image acquisition device are respectively connected to the control system.

[0013] Furthermore, preferably, at least three temperature and humidity sensors are respectively installed at the spray outlet of the atomizing mechanism, on the surface of the aquaculture material, and in the middle of the aquaculture material.

[0014] Furthermore, preferably, the isolation door is an automatic door.

[0015] Further, preferably: the screening mechanism includes a screen box, a vibrator, a screen mesh, a screen mesh frame, and a lifting mechanism; the screen box includes a left screen box and a right screen box, which are slidably installed together via a slide rail; the screen mesh is an elastic screen mesh, or the screen mesh includes a left screen mesh and a right screen mesh, which are slidably installed together via a slide rail; the screen mesh frame is provided with a telescopic mechanism, which is installed together with the screen box and can adjust the length of the screen box; the screen mesh frame is installed on the lifting mechanism.

[0016] Furthermore, preferably, the plurality of the aforementioned automatic aquaculture conveying mechanisms are arranged in a horizontal manner from front to back; Alternatively, several of the aforementioned automatic aquaculture conveying mechanisms may be arranged vertically from top to bottom; Or several of the aforementioned automatic aquaculture conveying mechanisms may be arranged in a mixed manner from front to back and from top to bottom.

[0017] Furthermore, preferably, the discharge end of the belt conveyor in the last step of the breeding process is equipped with a screening mechanism.

[0018] This invention also provides an automated insect larvae rearing or larvae pupation system, comprising several layers of the larvae rearing or larvae pupation device described in this invention.

[0019] Furthermore, preferably, it also includes a main control system, wherein the automatic aquaculture conveying mechanism and the single-layer screening mechanism are respectively connected to the main control system.

[0020] The beneficial effects of this utility model are: The device of this invention allows larvae / pupae to flow automatically along the conveyor belt, and feeding, screening, boxing, and transferring of larvae / pupae are completed in one go, significantly reducing labor intensity.

[0021] This invention allows switching between "gradually expanding box for larval rearing" and "gradually shrinking box for pupalization" by changing the conveyor belt spacing. During the larval rearing stage, larvae on the sieve enter larger boxes, simultaneously completing "box expansion + selection of strong larvae," with the rearing space gradually increasing to match the volume expansion needs of larvae during growth. During the pupation stage, pupae off the sieve enter smaller boxes, simultaneously completing "box shrinking + pupalization," simulating the pupae's need for concealed and compact space in the natural environment, improving the pupation success rate, forming a true "assembly line" rearing process with high equipment reuse rate and reduced fixed asset investment.

[0022] This invention reverse-couples spatial area difference with screening logic: for the first time, "area gradient" is used as a sorting / grading method, linked with particle size sorting of single-layer screens, compressing the traditional three-stage operation of "screening - manual boxing - manual transfer of pupae" into a single continuous flow. Through three major innovations, namely, dynamic spatial adjustment, screening-conveying coordination and closed material flow, it solves the core pain points of low space utilization, high dependence on manual labor and poor stage adaptability in insect farming. Its modular design further expands the application scenarios. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are also described.

[0026] Example 1 like Figure 1 As shown, an automated insect larvae rearing device 27 includes several stages of belt conveyors 1, with a square frame 2 on the top of the belt conveyors 1, and an isolation door at one or both ends of the square frame 2. A screening mechanism 3 is provided between every two of the automated material conveying mechanisms. The function of belt conveyor 1 is to realize the automatic conveying of bulk materials. Any material conveying equipment with the above function can be used. The number of belt conveyors 1 is set according to the growth habits of different insect larvae. In this embodiment, there are 3, but the number can also be set to 4, 5, 6, etc. as needed.

[0027] The structure of this embodiment is used for insect larval rearing and is suitable for insect rearing that uses powdered materials as feed, such as mealworms and yellow mealworms. In traditional rearing processes, manual sieving is generally used, followed by sorting into boxes or ponds to provide suitable rearing densities for insect larvae.

[0028] In this embodiment, a three-stage boxing process is adopted, using three belt conveyors 1, which are sequentially arranged as primary belt conveyor 1, secondary belt conveyor 1, and tertiary belt conveyor 1, with the area of ​​the breeding space of the three belt conveyors 1 increasing progressively.

[0029] The number of belt conveyors 1 in each level is allowed to vary. As above, each level of belt conveyor 1 corresponds to one belt conveyor 1, and the length of each level of belt conveyor 1 is different to facilitate the separation operation.

[0030] Alternatively, one belt conveyor 1 can be set up for a primary belt conveyor 1, two belt conveyors 1 can be set up for a secondary belt conveyor 1, and four belt conveyors 1 can be set up for a tertiary belt conveyor 1. The length of the belt conveyors 1 for different levels can be set according to actual needs, and can be the same or different.

[0031] The main function of the screening mechanism 3 is to separate the larvae and frass to avoid the frass affecting the larvae. Generally, a single-layer screening machine is sufficient. The specific structure of the screening machine can be selected according to the needs of the appropriate screening equipment, such as a vibrating screen or a rolling screen. In this embodiment, a single-layer vibrating screen is sufficient. The vibrating screen generally includes a screen box, a vibrator 22, a screen mesh, and a screen mesh frame 24. It is an existing device, and its specific structure will not be described in detail.

[0032] The feed inlet of the screening mechanism 3 is connected to the discharge end of the belt conveyor 1 mentioned above, and the larvae outlet (screen material outlet 4) of the screening mechanism 3 is connected to the feed end of the automated material conveying mechanism mentioned below.

[0033] The mesh size of the screen in the screening mechanism 3 at different positions is determined according to the actual screening situation, such as 8 mesh, 20 mesh, 40 mesh, and 60 mesh. Generally, the mesh size is larger in the later stages of screening.

[0034] like Figure 2 and 3 As shown, the main function of the square frame 2 is to combine with the belt conveyor 1 to form a rearing space for larvae; a common square frame 2 is sufficient. In this embodiment, the square frame 2 includes two side plates 6 and isolation doors on both sides of the side plates 6. The side plates 6 include vertical parts 7 and elastic arc-shaped parts 8 installed together in sequence. The side plates 6 can be a single integral structure or composed of several small side plates 6. With the above structure, the elastic arc-shaped parts 8 are in close contact with the conveyor belt, which effectively reduces friction on the conveyor belt during movement and improves its service life.

[0035] The aforementioned side panel 6 is suitable for open-style aquaculture, where the environmental conditions of the overall aquaculture space are controlled. For insect aquaculture requiring more precise environmental control, a sealed structure is needed, and the side panel 6 can adopt the following structures, such as... Figure 4 and 5As shown: The square frame 2 includes two side panels 6 and isolation doors on both sides of the side panels 6. The side panels 6 include an upper frame 9, a ventilation panel 10, a lower frame 12, and an elastic arc-shaped part 8, which are installed together in sequence. The ventilation panel 10 is provided with air holes 11, and a ventilation duct 30 is provided on the outside of the ventilation panel 10. The side panels 6 and the isolation doors form a sealed breeding space, which facilitates more precise control of breeding conditions and improves the precision of breeding.

[0036] Of course, other mechanisms that help control aquaculture can be added to the above structure, such as heat exchange mechanisms, temperature and humidity sensors 14, dissolved oxygen sensors, etc., to further improve the precision of aquaculture.

[0037] The isolation door can be either a manual door or an automatic door 5, depending on the actual situation. This embodiment uses an automatic door 5 to facilitate the automated operation of the equipment.

[0038] Based on the layout requirements of the aquaculture space, the arrangement of several belt conveyors 1 is as follows: like Figure 1 As shown, several of the belt conveyors 1 are arranged horizontally from front to back; Alternatively, several of the belt conveyors 1 may be arranged vertically from top to bottom; As shown in the figure, one or more belt conveyors 1 are arranged in a mixed manner from front to back and from top to bottom.

[0039] Of course, other arrangements can also be designed according to the actual factory layout, such as circular or cross-shaped arrangements.

[0040] The larval rearing device 27 in this embodiment also requires a feeding mechanism during operation. This feeding mechanism can be an automatic feeder from livestock and poultry farming equipment with multiple discharge ports, such as a gantry-type automatic feeder. This equipment is existing machinery and can be purchased as needed; further details are omitted.

[0041] The operation process of this embodiment: Feed and insect eggs are introduced into the primary belt conveyor 1, and the conditions are controlled for breeding. After a certain period of breeding, the primary belt conveyor 1 and the secondary belt conveyor 1 are turned on. The larvae and insect excrement bred in the primary belt conveyor 1 are screened by the screening mechanism 3. The screened larvae and new feed are distributed and introduced into the secondary belt conveyor 1 for breeding operations. At the same time as screening, new feed and insect eggs are introduced into the primary belt conveyor 1. After screening and feeding are completed, the breeding conditions of the primary belt conveyor 1 and the secondary belt conveyor 1 are controlled for graded breeding operations. After a certain period of breeding, the above steps are repeated. The larvae in the secondary belt conveyor 1 are screened and conveyed to the tertiary belt conveyor. At the same time, new feed is introduced into the tertiary belt conveyor for breeding. The above steps are repeated for the secondary and primary belt conveyors to complete the breeding operation and the start-up of the entire breeding equipment. After a certain period of time, the larvae in the three-stage belt conveyor 1 mature. Simultaneously, all three belt conveyors 1 are activated to perform egg-laying, sieving, larval transfer, and discharge operations, achieving automated production line operation for insect larvae. This effectively improves production efficiency and reduces labor costs. The lengths of the belt conveyors 1 at different levels are set according to the growth patterns of the insect larvae. Generally, it is required that the larvae in each level of belt conveyor 1 have a consistent growth time to ensure the automated production line operation of the entire system.

[0042] For the feeding operation of the above-mentioned equipment, a mobile gantry-type automatic feeder can be used, which moves the feed from one end of the belt conveyor to the other end. The feeding frequency is determined according to the larvae's consumption of feed, and a method of feeding larvae once and replenishing feed in batches can be adopted. Alternatively, a gantry-type automatic feeder can be fixed at the feed end of the belt conveyor and fed together with the screened larvae, with a method of feeding larvae once and feeding feed once.

[0043] Example 2 Insect larvae have long growth periods; for example, the larvae of the yellow mealworm typically grow for 80-130 days, with a maximum of 480 days and an average growth period of 120 days. To prevent feed spoilage during larval growth, a compound powdered feed with low moisture content, such as bran and cornmeal, is generally used. However, the low moisture content of these feeds cannot promptly replenish the water requirements for larval growth. Currently, fresh green fodder is commonly added for hydration. However, this method requires manual removal of any uneaten green fodder to prevent mold growth in the feed and subsequent larval death. This method is labor-intensive and inefficient. To address these issues, the solution adopted in this embodiment is as follows: like Figure 6 and 13As shown, it is basically the same as in Example 1, except that the larval breeding device 27 further includes an atomizing mechanism 16 and a layered control system. The belt conveyor, screening mechanism 3 and atomizing mechanism 16 are respectively connected to the layered control system.

[0044] The system employs an atomizing mechanism 16 and a tiered control system to replenish water according to the breeding needs. This increases the surface moisture of the concentrated feed, promptly meeting the larvae's water requirements. Simultaneously, the tiered control system precisely controls the atomization conditions, preventing high moisture content in the concentrated feed and thus avoiding mold growth. The atomizing mechanism 16 is standard equipment and can be purchased as needed; alternatively, an ultrasonic atomizing mechanism may be required. Figure 6 The image shows the atomizing tube.

[0045] To further improve the accuracy of supplementary control, the larval rearing device 27 of this embodiment also includes at least one of a temperature and humidity sensor 14, a video image acquisition device 15, and an observation port 13, wherein the temperature and humidity sensor 14 and the video image acquisition device 15 are respectively connected to the hierarchical control system.

[0046] At least three temperature and humidity sensors 14 are respectively installed at the spray outlet of the atomizing mechanism, on the surface of the aquaculture material, and in the middle of the aquaculture material.

[0047] By monitoring the temperature and humidity at different locations, the humidity of the concentrated feed can be controlled more precisely. At the same time, video image acquisition device 15 is used to collect image data in the breeding space. The layered control system is used to determine whether there is mold in the concentrated feed. It can also be observed through the observation ports 13.

[0048] Through the cooperation of the above-mentioned devices, atomization can be controlled more precisely, thereby effectively preventing feed from becoming moldy while replenishing moisture.

[0049] If tests show that the feed has a high moisture content and is at risk of mold, measures such as increasing ventilation and raising the temperature can be taken to dry it in a timely manner to eliminate the risk of mold.

[0050] Example 3 The screening mechanism 3 used in Example 1 is a fixed structure. The width of the overall screening mechanism 3 is greater than the distance between the two-stage belt conveyors 1, which is not a problem for single-layer aquaculture. However, for multi-layer aquaculture, if a fixed screening mechanism 3 is used, a screening mechanism 3 needs to be set up for each layer, resulting in high equipment investment costs. To solve the above problems, the screening mechanism 3 in this embodiment adopts the following structure: like Figure 9As shown, the screening mechanism 3 includes a screen box, a vibrator 22, a screen mesh, a screen mesh frame 24, and a lifting mechanism 18. The screen box includes a left screen box 20 and a right screen box 26, which are slidably installed together via a slide rail 22.

[0051] The screen is an elastic screen; if it is an elastic screen, then the screen does not need to be divided into two parts. If the screen is a rigid screen, then the screen includes a left screen 21 and a right screen 25, which are slidably installed together via a slide rail 22. The screen frame 24 is provided with a telescopic mechanism 19, which is installed together with the screen box and can adjust the length of the screen box. The screen frame 24 is mounted on a lifting mechanism 18.

[0052] The lifting mechanism 18 is a multi-functional lifting mechanical equipment, which can be divided into fixed and mobile types, guide rail type, articulated boom type, scissor type, chain type, loading and unloading platform, etc. It can be purchased according to needs. The chain type lifting mechanism 18 is used in this implementation.

[0053] In this embodiment, the sieve box and sieve mesh are divided into two parts. The length of the sieve box and sieve mesh is driven by the telescopic mechanism 19, thereby adjusting the length of the entire screening mechanism 3 so that it can be freely raised and lowered on the two-stage belt conveyor 1 to realize the screening operation of larvae breeding or larvae pupation devices at different levels.

[0054] like Figure 7 As shown, it is basically the same as in Example 1, except that the device in this example is used for larval pupation. During the larval pupation process, the number of larvae decreases, so the required breeding space also decreases. Therefore, the length of its belt conveyor 1 decreases step by step. Otherwise, there is no essential difference from larval breeding.

[0055] This embodiment discloses an automated insect larval pupation device, comprising three belt conveyors 1. A square frame 2 is mounted on top of each belt conveyor 1, and isolation doors are provided at both ends of the square frame 2. The belt conveyors 1 and the square frame 2 enclose a breeding space. A screening mechanism 3 is provided between every two belt conveyors 1. The area of ​​the breeding space of the several belt conveyors 1 gradually decreases. The feed inlet of the screening mechanism 3 is connected to the discharge end of the belt conveyor 1. The larval outlet (undersize outlet 17) of the single-layer screening mechanism 3 is connected to the feed inlet of the belt conveyor 1.

[0056] The operation process is basically the same as that in Example 1, and will not be described in detail here.

[0057] Based on the layout requirements of the aquaculture space, the arrangement of several belt conveyors 1 is as follows: like Figure 7As shown, several of the belt conveyors 1 are arranged horizontally from front to back; Alternatively, several of the belt conveyors 1 may be arranged vertically from top to bottom; like Figure 8 As shown, or several of the belt conveyors 1 are arranged in a mixed manner from front to back and from top to bottom.

[0058] Example 5 like Figure 10 and 14 As shown, an automated insect larvae rearing system includes several layers of larvae rearing devices 27 as described in Embodiment 1. The larvae rearing devices 27 are installed on the main frame, and different numbers of layers can be set as needed. In this embodiment, 5 layers are used.

[0059] The feeding equipment for the larval rearing system can be an automatic feeder from livestock and poultry farming equipment with multiple discharge ports, such as a gantry-type automatic feeder. This equipment is existing machinery and can be purchased as needed; further details are omitted.

[0060] The specific breeding process is basically the same as in Example 1, and will not be described in detail again.

[0061] The larval rearing system in this embodiment also includes a main control system. The main control system generally includes a control panel, circuit board, and programmable microcontroller, etc., which are conventional equipment; appropriate equipment can be selected according to needs.

[0062] The main control system of this utility model can be set according to the actual situation. For example, each layer and level can be set with a corresponding sub-control system. The electrical control components such as belt conveyor 1, screening mechanism 3 and automatic door 5 are connected to the sub-control system, and then each sub-control system is connected to the main control system.

[0063] Alternatively, electrical control components such as belt conveyor 1, screening mechanism 3, and automatic door 5 can be directly connected to the main control system, eliminating the need for a separate control system.

[0064] The specific method to use depends on the actual situation.

[0065] This embodiment adopts a three-dimensional aquaculture model, combined with a main control system, to effectively improve the scale of aquaculture and the degree of automation.

[0066] Example 6 like Figure 11-14 As shown, this embodiment is basically the same as Example 5, except that: this embodiment adopts a sealed breeding method, with different levels of larval breeding devices 27 installed on the frame, and sealing covers 29 set at the top and bottom of the frame to seal the space of the top and bottom layers, forming a sealed breeding structure, as shown in the figure. Figure 9As shown, ventilation ducts 30 of different layers are connected together, and air valves are installed on the ventilation ducts 30 to form air inlet and outlet channels on both sides of the equipment, thereby controlling the ventilation of the aquaculture system.

[0067] In this embodiment, side plate 6 adopts the following... Figure 3 and 4 The structure shown has an upper frame 9 in the side panel that contacts and seals with the conveyor belt of the upper belt conveyor 1, forming a sealed aquaculture space. The screening mechanism 3 adopts... Figure 9 The structure shown.

[0068] By installing environmental control equipment in different levels of aquaculture facilities, precise regulation of aquaculture parameters can be achieved, thereby improving aquaculture efficiency and effectiveness.

[0069] The larval pupation system and the larval rearing system are similar in structure, the main difference being that the length of the belt conveyor 1 is gradually shortened from the longest to the shortest. The specific structure will not be described in detail here.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
