Description

Technical Field

[0001] This utility model relates to the field of earthworm farming technology, and more specifically, to a foldable three-dimensional layered earthworm rearing rack. Background Technology

[0002] Earthworm farming has garnered widespread attention due to its important roles in organic waste treatment, soil improvement, and protein feed production. Traditional earthworm farming often employs flat rearing boxes or fixed multi-layered rack structures. These flat rearing methods suffer from significant space utilization issues, especially in urban environments with limited land resources or large-scale farming scenarios. This not only leads to high site costs but also restricts expansion opportunities. In terms of facility flexibility, fixed rearing facilities lack dynamic adjustment capabilities, making it difficult to flexibly adapt to changes in farming scale. Relocation or storage is inconvenient, making processes such as zoned feeding, harvesting earthworm castings, and transplanting adult earthworms difficult. Regarding standardized production, traditional rearing equipment has a low degree of standardization, and its construction and management rely excessively on experience. This hinders scientific and standardized production, becoming a key bottleneck restricting the industry's large-scale development. Furthermore, traditional non-folding rearing racks occupy significant storage space when idle, further increasing farming costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a foldable, multi-tiered earthworm rearing rack. Through the parallel, staggered movement of the front and rear support rods, the multi-tiered earthworm rearing boxes can be easily and quickly unfolded and folded. When unfolded, the multi-tiered rack fully utilizes vertical space, increasing the efficiency of the rearing space and facilitating flexible layout. When folded horizontally, the rack allows the earthworm rearing boxes to be laid flat and tightly packed, facilitating zoned feeding, harvesting earthworm castings, and transplanting adult earthworms. This invention improves space utilization while maintaining ease of operation and structural reliability, providing a novel equipment solution for modern intensive earthworm farming.

[0004] To achieve the purpose of this utility model, a foldable three-dimensional layered earthworm breeding rack is constructed, including a front support rod, a rear support rod, a breeding box, a front fixing post, and a rear fixing post. The front support rod is rotatably connected to the breeding box through a short movable connecting rod, and the rear support rod is rotatably connected to the breeding box through a long movable connecting rod. An movable gap is maintained between the short movable connecting rod and the long movable connecting rod, so that the front support rod and the rear support rod can move relatively parallel to each other.

[0005] The front support rod is in the shape of a branched main trunk. This irregular structure avoids the swing trajectory of the long movable link, ensuring no mechanical interference during the folding process.

[0006] One end of the front fixing post can be connected to the bottom of the lowest feeding box, and the other end can be connected to the ground. Both ends of the front fixing post can be detached.

[0007] One end of the rear fixed pile can be rotatably connected to the lower end of the rear support rod, and the other end can be connected to the ground. Both ends of the rear fixed pile can be disassembled.

[0008] The length of the protruding part at the top of the rear support rod is consistent with that of the rear fixing stake, ensuring that the breeding box remains horizontal after the three-dimensional layered earthworm breeding rack is folded.

[0009] The top of the rear support rod is connected by a crossbar to ensure the stability of the entire feeding rack structure;

[0010] The rearing box has a trough that can hold earthworm rearing substrate and feed.

[0011] This utility model has the following advantages:

[0012] This utility model features a parallel folding design for the front and rear support rods of the earthworm rearing rack, allowing the overall structure to be quickly expanded and contracted, significantly saving space in use, storage, and transportation. The tightly laid-out earthworm rearing box facilitates zoned feeding, harvesting earthworm castings, and transplanting adult earthworms. The foldable, three-dimensional, layered structure can form a highly efficient and intensive three-dimensional breeding system, possessing comprehensive advantages such as high space utilization, flexible operation, strong stability, and wide environmental adaptability.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 , Figure 2As shown, the embodiment provides a foldable three-dimensional layered earthworm rearing rack, including a front support rod 1, a rear support rod 2, a rearing box 3, a front fixing post 4, and a rear fixing post 5. The front support rod 1 is rotatably connected to the side wall of the rearing box 3 by using a short movable connecting rod 6, and the rear support rod 2 is rotatably connected to the side wall of the rearing box 3 by using a long movable connecting rod 7. A movable distance is maintained between the short movable connecting rod 6 and the long movable connecting rod 7, so that the front support rod 1 and the rear support rod 2 can move relatively parallel to each other, realizing the overall folding and unfolding of the earthworm rearing rack.

[0019] The front support rod 1 is in the shape of a branched main trunk. This irregular structure avoids the swing trajectory of the long movable connecting rod 7, ensuring no mechanical interference during the folding process.

[0020] The front fixing stake 4 adopts a ground nail structure. One end is connected to the bottom of the lowest feeding box 3 by a buckle, and the other end can be connected to the ground. Both ends of the front fixing stake 4 can be disassembled.

[0021] One end of the rear fixing post 5 is hinged to the lower end of the rear support rod 2 via a pivot to achieve a rotatable connection, and the other end can be connected to the ground. By lowering or raising the rear support rod, the earthworm feeding rack can be folded or unfolded. Both ends of the rear fixing post 5 can be disassembled.

[0022] The length of the protruding part at the top of the rear support rod 2 is consistent with that of the rear fixing post 5, ensuring that the breeding box remains horizontal after the three-dimensional layered earthworm breeding rack is folded, thus preventing the internal feed, earthworms, earthworm castings, etc. from spilling out.

[0023] The top of the rear support rod 2 is connected by a crossbar 8. The two ends of the crossbar 8 are bolted to the rear support rods 2 on the left and right sides respectively, forming a stable connection of the overall frame and preventing the support rod from lateral deformation and tilting.

[0024] The rearing box 3 has a trough that can hold earthworm rearing substrate and feed, ventilation holes in the box walls, and a water filter layer at the bottom.

[0025] Working Principle: In use, first connect one end of the front fixing post of the earthworm rearing rack to the bottom of the lowest rearing box, and insert the other end into the ground for fixation. Then, connect one end of the rear fixing post to the lower end of the rear support rod, and insert the other end into the ground for fixation. When filling with earthworms, feed, or collecting earthworm castings, pull the rear support rod from an upright position to a horizontal position. The rearing box will fold horizontally and can then be filled with earthworms and feed or have its castings collected. For intensive rearing, push the rear support rod upwards to a vertical position. The rearing boxes will unfold vertically and can be placed densely. When folding for storage, push the rear support rod to move it relatively parallel, causing the rearing boxes to gradually close together as the connecting rod rotates. During this process, the branched structure of the front support rod avoids intersecting with the long movable connecting rod. Finally, the protruding part at the top of the rear support rod is level with the bottom of the rear fixing post, ensuring the rearing box remains horizontal after folding. Disconnect and remove the front and rear fixing posts for convenient folding, transport, and storage.
