Description

Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, specifically, it relates to a circulating aquaculture rack for an environmental insect circulating aquaculture equipment. Background Technology

[0002] In existing technologies, insect farming is gradually becoming a green industry to replace traditional animal husbandry due to its high protein conversion efficiency, low environmental costs, and potential for waste resource utilization. Large-scale farming of environmental insects (such as black soldier flies) requires efficient and stable equipment support, and the recirculating farming rack, as a core component, directly affects the farming density, operational efficiency, and the insect growth environment.

[0003] Among the existing environmental insect breeding equipment, the commonly used breeding racks are planar breeding racks and vertical circulation breeding racks: Planar breeding racks are mostly single-layer or simple multi-layer planar layouts, with low space utilization, which cannot meet the needs of large-scale intensive breeding; while vertical circulation breeding racks usually have poor stability, which can easily cause the breeding box to shake, and the insects may escape or gather after being startled, affecting the uniformity of growth. In addition, the transmission parts are prone to dust accumulation or jamming, requiring frequent manual intervention. At the same time, multi-layer circulation requires high-power drive devices, resulting in high operating costs and high maintenance rates.

[0004] A Chinese patent application with application number CN2024209802168 discloses a driving device for the cyclical movement of environmental insect breeding boxes. The device includes a frame with several symmetrically rotatable steering sprockets on both inner walls of the frame. A circulating chain is wound around each steering sprocket. Multiple rows of stacked breeding boxes are arranged inside the frame, each box positioned between two circulating chains. A rotating shaft is fixed to each breeding box, with each end of the shaft rotatably passing through a corresponding circulating chain and rotatably connected to a guide wheel. Guide wheels adapted to a first guide rail are provided on the outer side of each circulating chain, and a second guide rail is provided on the inner side of each horizontal section of the circulating chain. A balance bar is fixedly fitted on the rotating shaft at a position corresponding to the second guide rail, with support rollers rotatably connected to both ends of the balance bar. The support rollers are adapted to the second guide rails. At least one clearance groove adapted to the rotating shaft is provided on each steering sprocket. This invention achieves automatic handling of breeding boxes, improving breeding quality.

[0005] However, the patent uses only a steering sprocket when changing layers, which makes the breeding box unstable and prone to shaking, causing the insects to be startled and scattered, and easily resulting in insects spilling out. Secondly, the patent uses a distance adjustment component to adjust the tension of the circulating chain. When the circulating chain needs to be tensioned, the entire rear frame needs to be moved, which increases the difficulty of operation and makes it difficult to achieve the tension of the circulating chain. Utility Model Content

[0006] The main technical problem this invention aims to solve is to provide a circulating breeding rack for an environmental insect circulating breeding equipment. This rack features a simple overall structure, ensures stable and smooth layer changing during breeding box operation, enables automatic feeding, and allows for convenient adjustment of the circulating chain tension, thereby improving the overall performance.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A circular breeding frame for an environmental insect circular breeding equipment includes a machine head frame, a front layer replacement support, a breeding support and a rear layer replacement support connected in sequence. The machine head frame, the front layer replacement support, the breeding support and the rear layer replacement support are all provided with symmetrically arranged and S-shaped circulating chains on both sides.

[0009] Multiple sets of second reversing groups are arranged from top to bottom on both sides of the front layer changing bracket, and a second drive device is fixedly installed on one side of the front layer changing bracket at the position corresponding to the second reversing group.

[0010] A first auxiliary reversing group and a second auxiliary reversing group are respectively installed on both sides of the rear floor changing bracket at positions corresponding to the second reversing group. The second auxiliary reversing group is located at the lower end of the rear floor changing bracket.

[0011] The second auxiliary reversing group is equipped with a tensioning device.

[0012] The following are further optimizations of the above technical solution by this utility model:

[0013] The circulating chain located at the head frame position is designated as the head area, the circulating chain located at the front layer changing bracket position is designated as the front layer changing area, and the circulating chain located at the rear layer changing bracket position is designated as the rear layer changing area.

[0014] Further optimization: The head frame is equipped with multiple sets of first reversing groups, which correspond to the reversing positions of the circulating chain head area. A discharge device is provided in the middle of the head frame, a feeding device is provided at the lower end of the head frame, and a first drive group is provided on one side of the lower end of the head frame. The first drive group is connected to the first reversing group in a transmission manner.

[0015] Further optimization: The positions of multiple second reversing groups correspond to the reversing points in the front layer-changing area of ​​the circulating chain.

[0016] Further optimization: The first auxiliary reversing group includes a steering wheel with a transmission installed at a corresponding position on the rear layer-changing bracket, and the steering wheel is meshed with a circulating chain.

[0017] Further optimization: An external gear is rotatably connected to the rear layer changing bracket above the steering wheel, and an internal gear meshes with the outer surface of the external gear. The internal gear is also rotatably connected to the rear layer changing bracket.

[0018] Further optimization: An arc-shaped plate is fixedly installed on the rear layer replacement bracket at one side of the outer surface of the internal gear.

[0019] Further optimization: The tensioning device includes an adjusting rack fixedly installed at the lower end of the rear layer replacement bracket, an adjusting gear meshing on the adjusting rack, and an adjusting shaft coaxially fixedly installed on the adjusting gear.

[0020] Further optimization: Two symmetrically arranged sliding plates are rotatably mounted on the adjustment shaft. The two sliding plates are simultaneously slidably mounted on the rear layer changing bracket, and the second auxiliary reversing group is fixedly mounted on the two sliding plates.

[0021] This utility model adopts the above-mentioned technical solution, with ingenious conception and reasonable structure. It can provide a low-cost, simple structure for the cyclic breeding of environmental insects, and ensure that the breeding box is stable and does not shake when changing layers. The breeding box also adopts a modular design, which enables the breeding box to automatically add breeding feed during operation and automatically flip over to unload the feed after breeding is completed. The overall operation speed is slow to ensure the breeding quality of the insects. In addition, the length of the breeding support can be changed according to the user's needs, making it flexible to use.

[0031] like Figure 1-7 As shown: A circular breeding frame for an environmental insect circular breeding equipment includes a machine head frame 1, a front layer replacement support 2, a breeding support 3 and a rear layer replacement support 4 connected together in sequence. The machine head frame 1, the front layer replacement support 2, the breeding support 3 and the rear layer replacement support 4 are all provided with symmetrically arranged and S-shaped circulating chains 6 on both sides.

[0032] Multiple sets of second reversing groups 21 are arranged from top to bottom on both sides of the front layer changing bracket 2. A second drive device 22 is fixedly installed on one side of the front layer changing bracket 2 at the position corresponding to the second reversing group 21.

[0033] On both sides of the rear floor changing bracket 4, a first auxiliary reversing group 41 and a second auxiliary reversing group 42 are respectively provided at positions corresponding to the second reversing group 21. The second auxiliary reversing group 42 is located at the lower end of the rear floor changing bracket 4.

[0034] The second auxiliary reversing group 42 is equipped with a tensioning device 5.

[0035] Multiple breeding boxes are connected in series on two circulating chains 6 (not shown in the figure). With this design, the breeding boxes can move under the drive of the circulating chains 6, eliminating the need for manual handling and improving breeding efficiency.

[0036] like Figure 7 As shown, the circulating chain 6 is configured as the head area 63 at the head frame 1, the circulating chain 6 is configured as the front layer changing area 61 at the front layer changing bracket 2, and the circulating chain 6 is configured as the rear layer changing area 62 at the rear layer changing bracket 4.

[0037] like Figure 2 As shown, multiple sets of first reversing groups 11 are provided on the head frame 1, and the positions of the multiple sets of first reversing groups 11 correspond to the reversing points of the head section 63 of the circulating chain 6.

[0038] A discharge device 13 is provided at the middle position of the machine head frame 1. In this embodiment, the discharge device 13 adopts a flipping structure commonly used in aquaculture equipment. That is, the box body is rotated by a motor, which can flip the worms that have been cultured in the box body and discharge them onto the conveyor belt for transportation. The specific structure will not be described in detail here.

[0039] A feeding device 14 is provided at the lower end of the machine head frame 1. In this embodiment, the feeding device 14 is driven by a motor and driven by a gear and rack, which drives the feeding pipe to move above the box to convey the feed, so that the feed can be evenly distributed in the box. The specific structure is existing technology and will not be described in detail here.

[0040] A first drive group 12 is provided at one side of the lower end of the machine head frame 1. The first drive group 12 is connected to the first reversing group 11. In this embodiment, the first drive group 12 uses a motor to drive a pulley to drive a belt to provide power.

[0041] With this design, the breeding box, driven by the first drive group 12 and the first reversing group 11, can automatically flip over to unload and automatically add breeding feed, reducing manual intervention and improving breeding efficiency.

[0042] like Figure 3 As shown, the second drive device 22 also uses a motor to drive a pulley to drive a belt to provide power. The second drive device 22 is connected to the second reversing group 21 in a transmission manner. The specific connection method is well known and will not be described in detail here.

[0043] The positions of the multiple sets of second reversing groups 21 correspond to the reversing points of the front layer-changing area 61 of the circulating chain 6.

[0044] like Figure 4-6 As shown, the first auxiliary reversing group 41 includes a steering wheel 410 that is driven and installed at a corresponding position on the rear reversing bracket 4, and the steering wheel 410 is meshed with the circulating chain 6.

[0045] An external gear 411 is rotatably connected to the rear layer changing bracket 4 above the steering wheel 410. An internal gear 412 meshes with the outer surface of the external gear 411, and the internal gear 412 is rotatably connected to the rear layer changing bracket 4.

[0046] The outer surface of the internal gear 412 has two symmetrically arranged concave grooves, and the upper end of the breeding box can be matched and engaged with the concave grooves.

[0047] An arc-shaped plate 413 is fixedly installed on the rear layer support 4 at one side of the outer surface of the internal gear 412, and a reversing groove is formed between the arc-shaped plate 413 and the concave groove of the internal gear 412.

[0048] With this design, the breeding box is connected in series on the circulating chain 6, and the circulating chain 6 is meshed with the steering wheel 410, so that the breeding box rotates with the steering wheel 410. At the same time, the upper end of the breeding box is engaged in the concave groove and rotates with the rotation of the internal gear 412, ensuring the stability of the breeding box in rotation. When changing direction, the upper end of the breeding box enters the reversing groove, further ensuring the stability of the box body in rotation without shaking.

[0049] A guide plate 414 is fixedly installed on the rear layer replacement bracket 4 above the steering wheel 410. A support plate 415 and a V-shaped slide rail 416 are fixedly installed below the guide plate 414. The support plate 415 and the V-shaped slide rail 416 are simultaneously fixedly installed on the rear layer replacement bracket 4.

[0050] With this design, the guide plate 414 contacts the upper end of the breeding box, playing a guiding and stabilizing role. The breeding box moves on the V-shaped slide rail 416 at the same time. With the support of the receiving plate 415, the breeding box forms multi-point support and stabilization when changing direction, which can further ensure its stable operation.

[0051] The tensioning device 5 includes an adjusting rack 51 fixedly installed at the lower end of the rear layer replacement bracket 4.

[0052] An adjusting gear 52 is meshed with the adjusting rack 51, and an adjusting shaft 53 is coaxially fixedly mounted on the adjusting gear 52.

[0053] Two symmetrically arranged sliding plates 54 are rotatably mounted on the adjustment shaft 53, and the two sliding plates 54 are simultaneously slidably mounted on the rear layer replacement bracket 4.

[0054] The second auxiliary reversing group 42 is fixedly installed on two sliding plates 54.

[0055] With this design, when the circulating chain 6 becomes loose during use, the adjusting shaft 53 can be rotated clockwise by wrench. Under the meshing action with the adjusting rack 51, the second auxiliary reversing group 42 will be moved away from the breeding support 3, which can tighten the loose circulating chain 6.

[0056] A locking nut is threaded onto the outer surface of the adjusting shaft 53 near the sliding plate 54. It is not shown in the figure. The locking nut can lock the adjusting shaft 53 to prevent loosening and facilitate adjustment.

[0057] The surface of the breeding support 3 has multiple ventilation holes, and the upper end of the breeding support 3 is connected to the air source (not shown in the figure). This design ensures that there is sufficient air in the breeding box on the breeding support 3, which is convenient for breeding.

[0058] In this embodiment, the commutation structure and principle of the first commutation group 11, the second commutation group 21, and the second auxiliary commutation group 42 are the same as those of the first auxiliary commutation group 41.

[0059] In addition to this embodiment, the length of the aquaculture support 3 can be increased or decreased as needed, and the length of the circulating chain 6 can also be increased or decreased, making it flexible and convenient to use.

[0060] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
