Description

Technical Field

[0001] This utility model belongs to the field of black soldier fly farming technology, specifically relating to a black soldier fly conveyor belt farming mechanism and a black soldier fly multi-layer farming device. Background Technology

[0002] Black soldier fly larvae only feed on decaying matter during their larval stage. The larvae are saprophytic and have a very wide range of food sources, including rotten fruit and leaves, kitchen waste, animal carcasses, and livestock and poultry manure. They convert organic waste into their own nutrients. The mature larvae can be fed to livestock, poultry, and aquatic animals. They can also be dried into powder and added to animal feed. Alternatively, they can be refined to produce animal protein, oils, and other products, thus realizing the resource utilization of waste. This has good economic and environmental benefits and is an important link in the natural food chain.

[0003] Black soldier fly larvae are raised using conveyor belt breeding beds, achieving continuous production. However, existing conveyor belt breeding beds for black soldier fly larvae suffer from fatal flaws due to insufficient consideration. They simply apply a conveyor belt and side plates to black soldier fly farming: First, the conveyor belt is prone to misalignment, causing larvae to fall off. Second, there is the issue of gaps between the conveyor belt and the side plates. The conveyor belt is made of plastic and has a certain degree of flexibility; the side plates are metal plates fixed on both sides. The conveyor belt can move forward under the drive of a motor. Therefore, no matter how precisely the breeding bed is installed during production, a certain gap will always exist between the conveyor belt and the side plates.

[0004] Black soldier fly larvae have a habit of burrowing into crevices, especially in the later stages of larval development, before pupation. A large number of larvae escape through these lateral crevices and hide in various places; approximately one-fifth or more of the mature larvae will escape through the lateral plate crevices. As a result, collecting these escaped larvae becomes extremely difficult, significantly reducing the practicality of conveyor belt culture beds. In fact, many early practitioners of conveyor belt culture have abandoned it, labeling it "unfeasible for raising black soldier flies using conveyor belt beds." Utility Model Content

[0005] To address the shortcomings described in the prior art, this utility model provides a black soldier fly larvae conveyor belt breeding mechanism and a black soldier fly larvae multi-layer breeding device.

[0006] The technical solution adopted in this utility model is as follows: A black soldier fly larvae farming mechanism using a conveyor belt includes a conveyor belt and rotating rollers. The conveyor belt is fitted onto two rotating rollers, and at least one anti-deviation guide strip is provided on the inner circulating end face of the conveyor belt, with the anti-deviation guide strip arranged along the length of the conveyor belt. Anti-deviation guide grooves are provided on the outer circumferential wall of the rotating rollers. The anti-deviation guide strips correspond one-to-one with the anti-deviation guide grooves, and are engaged in the anti-deviation guide strips. The anti-deviation guide strips can be directly injection molded integrally onto the inner circulating end face of the conveyor belt, or they can be assembled later. The engaging structure between the anti-deviation guide strips and the anti-deviation guide grooves guides the conveyor belt during its circulating transport, preventing it from deviating from its intended path. One rotating roller serves as the driving roller, and the other as the driven roller. The driving roller is driven by a motor.

[0007] As a preferred embodiment of this utility model, the conveyor belt is a skirted conveyor belt, and the skirt of the skirted conveyor belt plays a shielding role, which can prevent larvae on the conveyor belt from escaping.

[0008] As a preferred embodiment of this utility model, the outer circumferential wall of the rotating roller is provided with a rubber coating layer, and the anti-deviation guide groove is provided on the rubber coating layer.

[0009] As a preferred embodiment of this utility model, it also includes a conveying bracket, which includes a bracket plate and a support roller. The two bracket plates are arranged opposite each other along the length of the conveyor belt to form a support frame. Several support rollers are spaced apart along the width of the conveyor belt inside the support frame. A rotating roller is installed at the first and last ends of the support frame, and the inner circulation end face of the conveyor belt contacts the rotating roller and the support roller. Anti-deviation guide grooves are also provided on the support rollers.

[0010] As a preferred embodiment of this utility model, an escape-proof baffle is provided on the inner side of the skirt of the conveyor belt. The escape-proof baffle plays a primary blocking role. A small number of larvae may crawl through the escape-proof baffle, but due to the obstruction of the skirt, the larvae will not escape from the conveyor belt and will only hide in the folds of the skirt.

[0011] As a preferred embodiment of this utility model, the anti-escape baffle includes a baffle bracket and an anti-escape plate; the baffle bracket is mounted on the bracket plate, the bent part of the baffle bracket is located above the skirt edge, the anti-escape plate is fixedly connected to the bent part, and the anti-escape plate is located inside the skirt edge; the lower part of the anti-escape plate is provided with an elastic part, which is in gap contact with the conveying end face of the conveyor belt.

[0012] As a preferred embodiment of this utility model, the length of the anti-escape plate and the elastic part is less than the distance between the two rotating rollers, and the lengths of the anti-escape plate and the elastic part are the same, both being arranged along the length direction of the conveyor belt.

[0013] In a preferred embodiment of this invention, an outer protective baffle is provided on the support plate outside the skirt of the conveyor belt. The outer protective baffle further prevents any insects that manage to crawl out of the skirt, providing triple protection for the cultured insects.

[0014] As a preferred embodiment of this utility model, a skirt cleaning structure is provided on the output side of the conveyor belt to clean and collect insects hiding in the folds of the skirt. Moreover, the skirt is elastic and will be pulled open at the rotating roller, making it easy for the skirt cleaning structure to clean up the hidden insects.

[0015] As a preferred embodiment of this utility model, the skirt cleaning structure includes an air blowing structure and / or a roller brush structure. The air blowing structure uses an air blowing pipe, which is arranged along the width direction of the conveyor belt and spans the conveyor belt. Several air blowing ports are provided on the air blowing pipe, and the air blowing ports blow towards the skirt folds.

[0016] This utility model also provides a multi-layered breeding device for black soldier flies, including at least two conveyor belt breeding mechanisms, which are arranged in layers along the height direction; the conveyor belt breeding mechanism is the aforementioned conveyor belt breeding mechanism. The conveyor belt breeding mechanisms can be arranged in an alternating layered manner, that is, the end of the upper conveyor belt breeding mechanism corresponds to the beginning of the lower conveyor belt breeding mechanism; or they can be arranged in the same position in layers, that is, the upper and lower conveyor belt breeding mechanisms are of equal length, and a material guiding structure is set between adjacent conveyor belt breeding mechanisms to realize material transfer.

[0017] This invention adds an anti-deviation guide strip to the inner circulation end face of the conveyor belt and an anti-deviation guide groove to the rotating roller. The two fit together to guide the conveyor belt's circulation and prevent it from deviating. Furthermore, the conveyor belt uses a skirted conveyor belt, eliminating gaps in the breeding space and preventing insects from escaping. To avoid excessive insects hiding in the skirt, an escape-prevention baffle is installed on the inner side of the skirt, which initially prevents the insects from escaping. A small number of larvae may squeeze through the escape-prevention baffle, but due to the skirt's obstruction, they will not escape the conveyor belt and will only hide in the folds of the skirt. At the conveyor end, a skirt cleaning structure is used to clean and collect the hidden insects, improving the breeding effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides an embodiment of a black soldier fly larvae conveyor belt aquaculture mechanism, such as... Figure 1 As shown, the system includes a conveyor belt 1, a rotating roller 2, and a conveyor support 6. The conveyor support 6 includes a support plate 61 and support rollers 62. Two support plates 61 are arranged opposite each other along the length of the conveyor belt to form a support frame. Several support rollers 62 are spaced apart within the support frame along the width of the conveyor belt. Figure 4 As shown; a rotating roller 2 is installed at the first and last ends of the support frame, one of which is the driving roller and the other is the driven roller. The driving roller is driven by a motor 9; the conveyor belt 1 is sleeved on the two rotating rollers 2, and the inner circulation end face of the conveyor belt 1 is in contact with the rotating roller and the support roller; in this embodiment, the conveyor belt 1 is a skirted conveyor belt, and the skirt of the skirted conveyor belt plays a blocking role, which can prevent larvae on the conveyor belt from escaping.

[0026] like Figure 2 As shown, in order to prevent the conveyor belt from running off-center, at least one anti-deviation guide strip 3 is provided on the inner circulation end face of the conveyor belt 1. In this embodiment, three strips are provided. The anti-deviation guide strip 3 is arranged along the length direction of the conveyor belt 1. The anti-deviation guide strip can be directly injection molded into the inner circulation end face of the conveyor belt, or it can be assembled later.

[0027] The outer circumferential walls of the two corresponding rotating rollers 2 are provided with anti-deviation guide grooves 4; in order to reduce processing costs, the outer circumferential walls of the rotating rollers 2 are provided with rubber wrapping layers 5, the anti-deviation guide grooves 4 are provided on the rubber wrapping layers 5, and the support rollers 62 are also provided with anti-deviation guide grooves 4.

[0028] The anti-deviation guide strip 3 corresponds one-to-one with the anti-deviation guide groove 4. The anti-deviation guide strip 3 is inserted into the anti-deviation guide groove 4, such as... Figure 5As shown, the interlocking structure between the anti-deviation guide strip and the anti-deviation guide groove can guide the conveyor belt during its cyclic conveying process, preventing the conveyor belt from running off-track.

[0029] Because the skirt of the conveyor belt has folds, although the insects will not escape from the conveyor belt, they will hide in the folds of the skirt, which is also difficult to clean. Therefore, in order to reduce the number of insects hiding in the folds of the skirt, an escape-proof baffle is installed on the inner side of the skirt of the conveyor belt 1. It is preferable to install escape-proof baffles at both skirts. The escape-proof baffles play a primary blocking role. Even if a small number of larvae crawl through the escape-proof baffles, they will not escape from the conveyor belt due to the obstruction of the skirt and will only hide in the folds of the skirt.

[0030] Specifically, the anti-escape baffle includes a baffle bracket 71 and an anti-escape plate 72; a plurality of baffle brackets 71 are spaced apart and installed on a bracket plate, the bent part of the baffle bracket 71 faces the inside of the skirt and is located above the skirt, the anti-escape plate 72 is fixedly connected to each bent part, and the anti-escape plate 72 is located inside the skirt; the lower part of the anti-escape plate 72 is provided with an elastic part, which is in gap contact with the conveying end face of the conveyor belt, that is, there is a gap between the elastic part and the conveying end face of the conveyor belt, but the gap is relatively small.

[0031] Furthermore, the length of the anti-escape plate 72 and the elastic part is less than the distance between the two rotating rollers. The anti-escape plate and the elastic part are of the same length and are both set along the length of the conveyor belt. The elastic part is made of elastic strips, such as rubber strips.

[0032] A skirt cleaning structure is provided on the output side of conveyor belt 1 to clean and collect insects hiding in the folds of the skirt. The skirt is elastic and will be pulled open at the rotating roller, making it easy for the skirt cleaning structure to remove the hidden insects.

[0033] The skirt cleaning structure includes an air blowing structure 10 and a roller brush structure 11, such as Figure 1 , 3 As shown in Figure -5, the air blowing structure 11 uses an air blowing pipe, which is arranged along the width direction of the conveyor belt and spans the conveyor belt. Several air blowing ports are provided on the air blowing pipe, and the air blowing ports blow towards the skirt pleats. Of course, only the air blowing structure or the roller brush structure 11 can be provided. This embodiment provides both.

[0034] In order to further prevent insects from crawling out of the skirt, an outer protective baffle 8 is installed on the support plate 61 on the outside of the skirt of the conveyor belt. The outer protective baffle, the escape prevention baffle and the skirt provide triple protection for the cultivated insects.

[0035] To improve breeding efficiency, a multi-layer conveyor belt breeding structure can be used to create a three-dimensional breeding structure. This invention provides an embodiment of a multi-layer black soldier fly breeding device. The conveyor belt breeding mechanisms can be arranged in a staggered, layered manner, where the end of the upper conveyor belt breeding mechanism corresponds to the beginning of the lower conveyor belt breeding mechanism; alternatively, they can be arranged in a co-located, layered manner, where the upper and lower conveyor belt breeding mechanisms are of equal length. A material guiding structure is provided between adjacent conveyor belt breeding mechanisms to achieve material transfer. This embodiment uses four conveyor belt breeding mechanisms, such as... Figure 3-5 As shown, the adjacent conveyor belt breeding units are staggered, and the insect feeding device 12 and the feed feeding device 13 are installed at the uppermost conveyor belt breeding unit; the conveyor supports 6 of the four conveyor belt breeding units are connected and supported by columns.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
