Description

Technical Field

[0001] This utility model relates to the field of silkworm breeding equipment technology, and in particular to a silkworm rearing frame that is easy to store. Background Technology

[0002] The silkworm, scientifically known as *Bombyx mori*, is a holometabolous insect belonging to the family Bombyx mori in the order Lepidoptera. Its life cycle includes four stages: egg, larva, pupa, and adult. During the larval stage, it undergoes four molts to become a fifth-instar larva. After feeding on mulberry leaves for about eight days, it matures into a silkworm and finally spins a cocoon. The silk produced is used to make various silk products and plays an important role in the textile industry. Silkworm racks are common silkworm rearing equipment, typically multi-layered structures made of wood, bamboo, or metal tubing. By placing silkworm beds on the racks, three-dimensional rearing of silkworms can be achieved, thus improving rearing efficiency. Existing silkworm racks are all placed on the ground, are large, and difficult to store. Since the space inside the silkworm rearing room is limited, the equipment not needed after the mature silkworms are spun stalks takes up a large area, leading to insufficient space in the rearing room.

[0003] To address the aforementioned issues, Chinese utility model patent No. 202420724621.3 discloses a simple, manually adjustable silkworm rearing frame, comprising a top rod, connecting ropes, and a silkworm platform. The top rod is fixed to the top of the silkworm house, and four connecting ropes are movably connected to it. Each connecting rope consists of two ropes connected to several fixing components. The protrusions at the four corners of the silkworm platform are placed between two ropes and rest on the fixing components. This utility model allows the position of the silkworm platform to be changed by adjusting the position of the fixing components. When the silkworm frame is not in use, adjusting the position of the silkworm platform to the upper part of the room frees up space at the bottom of the silkworm house, providing space for subsequent silkworm rearing operations and effectively solving the problem of the silkworm frame being difficult to store. However, the frame of this utility model is constructed of ropes, and during operations such as feeding mulberry leaves and adjusting the height of the silkworm platform, the entire frame is prone to violent shaking. Furthermore, the silkworm platform relies solely on the elastic clamping force of the fixing components for support and fixation. However, during long-term up-and-down sliding adjustments, the clamping force of the fixing components may loosen, easily causing the silkworm platform to slip. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a silkworm rearing frame that is simple in structure, stable in frame, and easy to store.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a silkworm frame that is easy to store, including two top rods symmetrically fixed to the top of the silkworm house. Each top rod has a connecting pipe assembly fixed to both ends. The connecting pipe assembly includes a first connecting pipe and a second connecting rod. Both are provided with multiple connecting holes at intervals. The two are sleeved together and detachably fixed by a fixing member I. The first connecting pipe is fixed to the top rod. Multiple U-shaped brackets are detachably fixed to the second connecting rod. The U-shaped brackets connect two adjacent second connecting rods. The U-shaped brackets are composed of a connecting piece and two side rods vertically fixed to both ends of the back of the connecting piece. The side rods away from the connecting piece are provided with threads. The two side rods of the U-shaped bracket pass through the connecting holes on the two adjacent second connecting rods and are fixed by a fixing member II. The U-shaped brackets support the silkworm table and are snapped together with it.

[0006] Optionally, the connecting piece is provided with a limiting groove, and the bottom of the silkworm platform is provided with a protrusion that matches the limiting groove, and the protrusion is inserted into the limiting groove.

[0007] Optionally, the length of the first connecting pipe is two-thirds of the length of the second connecting rod.

[0008] Optionally, the connecting holes are evenly spaced and aligned along the axial direction of the connecting rod assembly.

[0009] Optionally, taking into account the height of the silkworm rearing platform during use and subsequent storage, the fixing component I is a bolt and a nut, and the fixing component II is two nuts.

[0010] Optionally, to reduce the space occupied during storage, the side rods and connecting pieces are detachably fixed.

[0011] Optionally, to ensure the structural strength of the silkworm frame, the top rod, connecting pipe assembly, and side rod are made of stainless steel or aluminum alloy.

[0012] The usage of this utility model is as follows: First, the worker secures the second connecting rod to the bottom of the first connecting pipe using nuts and bolts. Next, the assembled U-shaped bracket is secured to the second connecting rod using two nuts. Finally, the silkworm rearing platform is placed on the U-shaped bracket, and the protrusion at the bottom of the platform is inserted into the limiting groove to fix it in place. Silkworms can then be raised on the platform. Once the mature silkworms have hatched, and the platform is not in use, the platform, U-shaped bracket, and second connecting rod are disassembled. The second connecting rod is then fully inserted into the first connecting pipe, ensuring the first connecting pipe covers the second connecting rod to the maximum extent, forming a retractable connecting pipe assembly. The two are then secured with bolts and nuts, fixing the second connecting rod above the silkworm rearing room. The disassembled platform, U-shaped bracket, and fasteners can be stored separately or installed on the retractable connecting pipe assembly in the same way as before, allowing the entire frame to retract and fix above the silkworm rearing room, forming a compact suspended state without requiring additional ground storage space.

[0013] The principle of this invention is as follows: the connection between the top rod and the top of the silkworm house achieves the fixation and suspension of the entire device; the U-shaped bracket provides support for the silkworm platform; the protrusion limits and fixes the silkworm platform; the height of the silkworm platform can be adjusted by changing the connection holes of the U-shaped bracket inserted into the second connecting rod at different positions; during storage, by fully inserting the second connecting rod into the interior of the first connecting tube, the previously exposed second connecting rod is wrapped up using the sleeve structure of the two, significantly reducing the height of the frame and the vertical space occupied, so that the entire frame is fixed at about one-third of the height above the silkworm house, leaving about two-thirds of the space below the silkworm house free for subsequent silkworm rearing operations; the detachable design of the first connecting tube, the second connecting rod, the U-shaped bracket, and the silkworm platform facilitates the breakdown of the large silkworm frame into smaller components for individual storage, thereby reducing storage space; by setting equally spaced and axially aligned connection holes of the same size on the first connecting tube and the second connecting rod, the disassembled U-shaped bracket and silkworm platform can be suspended and supported on the retracted connecting tube assembly. This invention completes the entire silkworm rearing frame using four components: a top rod, a connecting pipe assembly, a U-shaped bracket, and a silkworm rearing platform. The connection method between the components facilitates quick assembly and disassembly of the device. The entire device has a simple structure with no redundant connecting parts, and all components use standard parts, which helps reduce the cost of replacement and maintenance in the future. The top rod, connecting pipe assembly, and side rod are made of sturdy metal materials, which further ensures the stability of the entire silkworm rearing frame structure.

[0014] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, a stable frame, and is easy to store, which helps to save storage space and improve the space utilization rate of the silkworm house. Attached Figure Description

Detailed Implementation

[0019] Example 1, in conjunction with the following Figures 1-3Further description of this utility model: A silkworm frame that is easy to store includes two top rods 1 symmetrically fixed to the top 12 of the silkworm house by expansion bolts. Each top rod has two connecting pipe assemblies 2 welded to both ends. Each connecting pipe assembly includes a first connecting pipe 3 and a second connecting rod 4. Considering the height of the silkworm platform during use and subsequent storage, the length of the first connecting pipe is two-thirds that of the second connecting rod. Multiple identical and axially aligned connecting holes are evenly spaced along the axis of the rod body on both the first and second connecting pipes. The central axis of the connecting holes is parallel to the central axis of the top rod. The spacing between the connecting holes on the first connecting pipe is equal to the spacing between the connecting holes on the second connecting rod. The second connecting rod is sleeved onto the first connecting pipe. To ensure that the connecting holes at the same position on each second connecting rod are at the same horizontal height, the second connecting rod and the first connecting pipe are fixed together through the connecting holes and a fixing member I5. The first connecting pipe is welded to the top rod using bolts and nuts. Multiple U-shaped brackets 6 are detachably fixed to the body of the second connecting rod. Each U-shaped bracket includes a connecting piece 7 and two side rods 8. The two side rods are vertically welded or fixed to the two ends of the back of the connecting piece using bolts and nuts. The ends of the side rods furthest from the connecting piece are threaded. The two threaded ends of the U-shaped bracket pass through connecting holes at the same horizontal level on two second connecting rods in the same row. Then, the threads on the side rods engage with the fixing part II9 (two nuts), clamping the second connecting rod between the two nuts on the side rods. This simultaneously fixes the U-shaped bracket to two second connecting rods in the same row. Multiple U-shaped brackets longitudinally connect adjacent second connecting rods. When one threaded end of the U-shaped bracket is inserted into the connecting hole on the second connecting rod, the other threaded end of the U-shaped bracket is simultaneously inserted into the connecting hole on another second connecting rod in the same row, thus achieving rapid positioning and saving assembly time. The U-shaped support frame is equipped with a silkworm rearing platform 10. Two U-shaped supports in the same row simultaneously support the same silkworm rearing platform. The platform is rectangular, and its size is smaller than the rectangle formed between the second connecting rods. A limiting groove 11 is provided on the connecting piece. Protrusions matching the limiting grooves are glued to both ends of the bottom of the platform. These protrusions simultaneously engage with the limiting grooves of the two U-shaped supports in the same row, restricting the movement of the platform. To ensure the structural strength of the silkworm rearing frame, the top rod, connecting pipe assembly, and side rods are made of stainless steel or aluminum alloy. To facilitate support of the platform, the U-shaped supports are made of stainless steel square tubing, and the platform itself is made of bamboo or wood.
