Description

Technical Field

[0001] The embodiments of the present invention relate to the field of black soldier fly farming technology, specifically, to a black soldier fly egg collection device for black soldier fly farming. Background Technology

[0002] Black soldier flies, as highly efficient insects for converting organic waste, have larvae that can process kitchen waste, livestock manure, and other wastes. The larvae hatched from the eggs laid by the adults possess both environmental purification and protein resource value, making them a core species in large-scale ecological farming and waste treatment. In the black soldier fly farming industry chain, egg collection is a crucial link between adult breeding and larval rearing. Stable and efficient egg collection ensures a continuous supply of larvae, directly impacting the scale of farming and waste treatment efficiency. Therefore, the efficiency and stability of egg collection technology are significant factors restricting the large-scale application of black soldier flies.

[0003] In traditional insect egg collection, cardboard, foam board, or plastic board are often used as collection carriers. The surface of the board is usually coated with moist bran slurry or humus to simulate the oviposition substrate preferred by adult black soldier flies. The collection board is placed at an angle in the corner of the adult breeding cage to match the adult flies' oviposition habits of avoiding light and preferring crevices. After the adults lay eggs on the surface or edge crevices of the collection board, the collection board is manually removed periodically every 24-48 hours, and tools such as scrapers and brushes are used to scrape the egg masses or scattered eggs on the board into the collection container. Traditional manual collection using collection boards relies on manual operation. However, in large-scale breeding, a single adult insect breeding cage needs to be equipped with 10-20 collection boards. Every day, each board needs to be manually removed, scraped, cleaned, and repositioned. This operation is tedious and involves a large amount of repetitive labor. Furthermore, frequent manual contact between the collection boards and the breeding cage can easily introduce external pathogens. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a black soldier fly larvae egg collection device, which solves the technical problems of existing technologies where egg collection relies on manual operation, which is cumbersome, involves a large amount of repetitive labor, and involves frequent manual contact with the collection plate and the breeding cage, making it easy to introduce external pathogens.

[0005] According to one aspect, at least one embodiment of the present invention provides a black soldier fly larvae egg collection device, comprising: a plurality of collection plates arranged at intervals, wherein a collection slit for black soldier flies to lay eggs is formed between two adjacent collection plates; A collection platform is provided on one side of the collection plate, and the upper surface of the collection platform is provided with a collection trough for collecting insect eggs; The scraper has several blades, each corresponding to one of the collection slots. The scraper is raised, lowered, and rotated within the collection slot. The sidewall of the scraper contacts the sidewall of the collection slot. The scraper can move from bottom to top to scrape off the insect eggs on both sides of the collection slot and support the scraped-off insect eggs. The scraper can rotate to an inclined position and guide the supported insect eggs to the collection trough.

[0006] For example, in a black soldier fly larvae breeding egg collection device provided in at least one embodiment of the present invention, a plurality of collection plates are arranged at intervals along the periphery of the collection platform.

[0007] For example, in at least one embodiment of the present invention, a black soldier fly larvae egg collection device is provided, wherein a groove is provided vertically along the side wall of the collection plate, a slider is slidably disposed in the groove, and the collection plate is disposed on the slider; the black soldier fly larvae egg collection device further includes: A movable platform is raised and lowered on the collection plate. The movable platform has the same number of rods as the collection slots and corresponds one-to-one with each collection slot. The movable platform can move so that the rods can be raised and lowered within the collection slots. A connecting rod is mounted on the moving platform at one end and on the scraper at the other end. The connecting rod can move up and down with the moving platform and drive the scraper to move up and down synchronously.

[0008] For example, in a black soldier fly larvae breeding egg collection device provided in at least one embodiment of the present invention, the chute has an upper sidewall, which is used to abut against the slider to limit the upward movement of the slider; One end of the connecting rod is rotatably mounted on the end of the scraper away from the slider. The scraper is rotatably connected to the slider. The scraper is configured such that when it moves upward to the point where the slider abuts against the upper sidewall, the scraper can be pushed by the connecting rod and rotated around the axis of rotation of the scraper and the slider to an inclined position, so as to guide the supported insect eggs to the collection trough.

[0009] For example, in at least one embodiment of the present invention, a black soldier fly larvae egg collection device is provided, which further includes a torsion spring, one end of which is disposed on the scraper and the other end of which is disposed in the slider. The torsion spring is used to maintain the scraper in a horizontal state as it moves up and down in the chute.

[0010] For example, in a black soldier fly breeding egg collection device provided in at least one embodiment of the present invention, the collection slit has an egg accumulation area, which is located in the area away from the center of the collection slit; The scraper has a collecting section and a scraping section, and the scraping section has two parts, located on both sides of the collecting section; The scraping section is arranged at an angle relative to the collecting section. The scraping section extends outward from the connection point with the collecting section, and its height gradually increases. The scraping section is used to scrape off insect eggs at an angle.

[0011] For example, in a black soldier fly larvae breeding egg collection device provided in at least one embodiment of the present invention, the scraper has a temporary storage groove in the middle, and the groove wall near the side wall of the collection slot is inclined to guide the scraped-off eggs to the temporary storage groove in the middle.

[0012] For example, in a black soldier fly larvae breeding egg collection device provided in at least one embodiment of the present invention, the moving platform has an abutment part, the collection platform can move upward and abut against the abutment part, and drive the moving platform to move upward synchronously.

[0013] For example, in a black soldier fly breeding egg collection device provided in at least one embodiment of the present invention, the breeding shed has an isolation plate, which is used to divide the breeding shed into a breeding area and an egg collection area distributed vertically, and the isolation plate is provided with an opening; A fixing element is provided on several of the collection plates, the fixing element is located within the breeding area, and is used to suspend several of the collection plates above the isolation plate; A linear drive unit is disposed within the egg retrieval area. The moving end of the linear drive unit is provided with a pusher plate, which is used to support the collection platform. The linear drive unit can drive the pusher plate to move, thereby moving the collection platform up to the breeding area or down to the egg retrieval area.

[0014] For example, in a black soldier fly larvae breeding egg collection device provided in at least one embodiment of the present invention, the size of the pusher plate is matched with the size of the opening to block the opening.

[0015] The beneficial effects of the embodiments of the present invention are as follows: In this invention, the scraper can move vertically up and down along the collection seam to scrape off the insect eggs attached to the side walls, avoiding omissions or residues during traditional manual scraping. The scraped-off insect eggs are directly supported on the scraper surface, preventing them from falling and being lost. The scraper can be rotated to an inclined state, and the insect eggs supported on its surface can slide naturally along the inclined surface to the central collection platform, where they are collected centrally through the collection trough, eliminating the need for manual scraping and transfer of each plate.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0020] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0021] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-7 As shown, it illustrates a black soldier fly larvae collection device for breeding according to an embodiment of the present invention. In some examples, the collection platform 300 is a block or disc-shaped structure, and the collection plates 200 are fan-shaped structures. The collection plates 200 are distributed at intervals along the periphery of the collection platform 300, that is, the collection plates 200 are evenly arranged around the outer periphery of the collection platform 300. The collection platform 300 is located at the center of the area surrounded by several collection plates 200, and its upper surface is provided with a collection groove 310 as a central convergence area for receiving insect eggs.

[0026] The gap between two adjacent collecting plates 200 forms a collecting slit 210, which runs vertically through the collecting plate 200. Its width is adapted to the oviposition slit size preferred by adult black soldier flies, providing a natural oviposition site for black soldier flies.

[0027] The scraper 400 is a plate-shaped component adapted to the width of the collection slot 210. The number of scrapers corresponds one-to-one with the collection slots 210, with each scraper 400 embedded within its corresponding slot. The side walls of the scraper 400 contact the side walls of the collection slot 210, i.e., the opposite side walls of two adjacent collection plates 200, ensuring close contact with the surface where the insect eggs adhere. The scraper 400 can move vertically up and down along the collection slot 210, scraping off the insect eggs attached to the side walls, avoiding omissions or residues during traditional manual scraping. The scraped-off insect eggs are directly supported on the surface of the scraper 400, preventing them from falling and being damaged. The scraper 400 can be rotated to an inclined state, allowing the insect eggs supported on its surface to slide naturally along the inclined surface towards the central collection platform 300, where they are collected centrally through the collection trough 310, eliminating the need for manual scraping and transfer of each plate.

[0028] Furthermore, the sidewall of the collecting plate 200, i.e., the inner sidewall of the collecting slot 210 formed by adjacent collecting plates 200, is provided with a vertical groove 220. The groove 220 is an elongated groove, in which a slider 230 is slidably disposed. The scraper 400 is connected to the slider 230 through a rotating shaft. The scraper 400 can rotate freely around the rotating shaft and simultaneously rise and fall synchronously with the slider 230 along the groove 220. The moving platform 500 has a frame-like structure and is embedded inside several collection plates 200. It can rise and fall vertically along the collection plates 200. The moving platform 500 has several rods 510, the number of which corresponds one-to-one with the collection slots 210. After the moving platform 500 moves, each rod 510 can rise and fall synchronously with the moving platform 500 and embed itself into the corresponding collection slot 210. Each rod 510 is equipped with a pivot. One end of the connecting rod 600 is rotatably connected to the rod 510 of the moving platform 500 through the pivot, and the other end is rotatably connected to the end of the scraper 400 away from the slider 230, that is, the end of the scraper 400 near the outside of the collection slot 210, through the pivot. The upper sidewall 221 of the chute 220 is the horizontal wall at the top of the chute 220. When the slider 230 moves up to the top of the chute 220, the upper end face of the slider 230 abuts against the upper sidewall 221, restricting the slider 230 from moving further up. That is, the middle part of the scraper 400 is limited. The torsion spring 240 is sleeved on the rotation axis of the scraper 400 and the slider 230. One end is fixed to the scraper 400 and the other end is fixed inside the slider 230. In its natural state, it is in a slightly compressed state. The elastic force forces the scraper 400 to maintain a horizontal posture, so that the scraper 400 as a whole is perpendicular to the vertical direction of the collection slit 210, so that the scraped insect eggs can be stably supported on the surface of the scraper 400 and will not fall prematurely due to the tilt of the scraper 400. When the scraper 400 moves upward with the slider 230 to the top of the chute 220, the slider 230 is limited by the upper side wall 221 and cannot continue to rise. However, the moving table 500 can continue to drive the connecting rod 600 upward. At this time, the connecting rod 600 pushes the end of the scraper 400 away from the slider 230 upward. The scraper 400 overcomes the elastic force of the torsion spring 240 and rotates around the rotation axis with the slider 230, changing from a horizontal state to an inclined state. The inclined scraper 400 surface forms a guide slope, which slides the supported insect eggs into the central collection trough 310, completing the automatic unloading.

[0029] Furthermore, the scraper 400 is divided into three parts along its length: a collection section 410 in the middle and scraping sections 420 symmetrically distributed on both sides. The scraping sections 420 are arranged at an angle relative to the collection section 410. As they extend outward from the connection point with the collection section 410, i.e., towards both ends of the collection slit 210, the height of the scraping sections 420 gradually increases, forming an inclined surface that is higher on the outside and lower on the inside. Its inclined length can cover the egg accumulation area 250 of the collection slit 210. When the scraper 400 moves up and down, the inclined surface of the scraping sections 420 can scrape the eggs along the wall of the accumulation area, reducing tearing or crushing of the egg masses and lowering the egg breakage rate. At the same time, the two scraping sections 420 correspond to the egg accumulation areas 250 on both sides of the collection slit 210, allowing for simultaneous scraping of eggs from both sides and avoiding omissions on one side.

[0030] Temporary storage troughs 430 are provided in the middle of the collection section 410 and the middle of the scraping section 420, with the openings facing upwards, to temporarily support the scraped-off insect eggs. The two sides of the temporary storage trough 430 near the side wall of the collection seam 210 are arranged at an angle. The insect eggs scraped off by the scraping section 420 will slide along its inclined surface to the middle collection section 410, and the inclined walls of the temporary storage trough 430 will further guide the insect eggs on both sides into the temporary storage trough 430, so that the scraped-off insect eggs will not fall off the edge of the scraper 400 during the lifting and lowering process of the scraper 400.

[0031] The abutment portion 520 of the moving platform 500 is a protruding structure, such as an edge flange, on the side of the moving platform 500 facing the collection platform 300, and its position corresponds to the top of the collection platform 300. When the collection platform 300 moves upward, its upper surface can directly contact the abutment portion 520 and apply an upward thrust, thereby driving the moving platform 500 to rise synchronously.

[0032] In some examples, the breeding shed 100 is a closed or semi-closed cavity structure with a horizontal partition 130 inside, dividing the breeding shed 100 into two independent areas, the upper one being the breeding area 110, where black soldier fly adults are active, mate, and lay eggs, and where a suitable temperature, humidity, and light-proof environment must be maintained; the lower one being the egg collection area 120, where operators collect eggs and maintain equipment.

[0033] In this example, the fixing member 700 is a bracket or hook structure, with one end connected to the top of several collection plates 200, and the other end fixed to the top frame of the breeding shed 100 via a hanger. All collection plates 200 are suspended as a whole within the breeding area 110 above the isolation plate 130, avoiding temperature conduction interference caused by contact between the collection plates 200 and the isolation plate 130. The suspension layout also ensures that the collection slits 210 are fully exposed to the breeding area 110, facilitating adult insects to find and enter the slits to lay eggs, further increasing the aggregation of eggs within the collection slits 210, improving the utilization rate of the collection slits 210 by adults, and increasing the number of eggs attached per unit area.

[0034] The partition plate 130 has an opening 131 in the middle, which is a through opening from top to bottom. Its position corresponds to the moving path of the collection platform 300 and the push plate 810. The linear drive component 800, such as an electric push rod or a cylinder, is vertically installed at the bottom of the egg collection area 120 or on the support. Its moving end, i.e. the top of the telescopic rod, is fixedly connected to the push plate 810. The upper end of the push plate 810 is used to support the collection platform 300, and the size of the push plate 810 matches the size of the opening 131 of the partition plate 130. When the push plate 810 descends to the egg collection area 120, it can cover the opening 131 and block it. When the push plate 810 rises, it can pass through the opening 131 and drive the collection platform 300 into the breeding area 110. After the pusher plate 810 descends to the collection platform 300, it can completely block the opening 131, preventing odors, moisture or insects from the breeding area 110 from falling into the egg collection area 120, and at the same time preventing dust and debris from the egg collection area 120 from entering the breeding area 110 and polluting the environment.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
