Description

Technical Field

[0001] This utility model relates to the technical field of Hirudo medicinalis seedling cultivation devices, specifically, to a stratified cultivation and observation device for Hirudo medicinalis seedlings. Background Technology

[0002] As a traditional and valuable Chinese medicinal herb, the saliva of the leech contains hirudin, an important medicinal component with anticoagulant and antithrombotic properties. With increasing medicinal demand, the scale of artificial breeding has been expanding year by year. Seedling cultivation is a crucial stage in leech farming, as its survival rate and growth status directly determine the farming efficiency. Because the seedlings are small and have weak mobility, strict requirements are placed on the isolation and protection of the breeding environment, the removal of impurities, and the observation of growth.

[0003] Currently, conventional breeding of Hirudo nipponia juveniles mostly adopts a single-box mixed-culture model, which has problems such as mutual interference among juveniles, difficulty in cleaning impurities, and inconvenience in observation, thus restricting the survival rate. If most are mixed-cultured in a single box, the dense clustering of juveniles easily leads to competition for food and biting, especially when there are large differences in the physical condition of the juveniles, weaker individuals are easily attacked, resulting in a survival rate of less than 60%. Some simple partition devices use straight plates for division, which enclose the space and do not have independent activity areas, affecting the normal crawling and feeding of juveniles.

[0004] Furthermore, the existing impurity separation design of cultivation devices is unreasonable. On the one hand, impurities such as seedling feces and residual feed are mixed with the seedlings in the same space, lacking a filtration and separation structure. The accumulation of impurities easily leads to water quality deterioration and bacterial growth. Moreover, cleaning impurities requires frequent turning of the seedlings, which can easily cause stress to the seedlings. On the other hand, although some devices are equipped with filters, the filters are fixedly connected to the tank. When cleaning, the seedlings must be removed as a whole, which is cumbersome and can easily lead to the escape or damage of the seedlings, affecting the stability of cultivation. In view of this, we propose a stratified cultivation and observation device for Hirudo nipponia seedlings. Utility Model Content

[0005] The purpose of this invention is to provide a stratified cultivation and observation device for Hirudo nipponia seedlings to address the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A layered cultivation and observation device for Hirudo nipponia seedlings includes a steel frame. Multiple inner support blocks are fixedly installed on the inner surfaces of the left and right side panels of the steel frame. A transparent cultivation box is detachably installed on two symmetrical inner support blocks. A rectangular frame is inserted into the transparent cultivation box, and an inner support net is provided at the bottom of the rectangular frame. The Hirudo nipponia seedlings are positioned above the inner support net, and impurities fall down along the inner support net to below it. A honeycomb partition plate with a honeycomb-shaped perforated structure is inserted into the rectangular frame. An escape-proof cover is placed on the top surface of the transparent cultivation box, and a breathable barrier net is provided at the center of the escape-proof cover.

[0007] Preferably, the inner support pad has a central hole, and a plug-in protrusion is fixedly installed on the bottom surface of the transparent incubator, with the plug-in protrusion and the central hole being plugged in and engaged. This feature facilitates the assembly of the transparent incubator with the steel frame.

[0008] Preferably, handles are fixedly installed on both the front and rear sides of the transparent incubator, and the cross-section of the handles is arc-shaped.

[0009] Preferably, a drain pipe is fixedly installed on the side of the transparent incubator, and a manual valve is fixedly installed on the drain pipe; This setting allows you to open the manual valve later for sewage discharge.

[0010] Preferably, handle grooves are provided on the inner walls of the left and right side plates of the rectangular frame, and the depth of the handle grooves is between 5mm and 12mm.

[0011] Preferably, the transparent incubator is provided with insertion holes at all four corners, and positioning posts are fixedly installed on the bottom surface of the four corners of the escape-proof cover, with the positioning posts and insertion holes being inserted into each other. This feature enables the positioning and installation of the escape-proof cover to prevent lateral deviation.

[0012] Preferably, the length of the positioning post is between 1cm and 1.5cm, and the bottom end of the positioning post is truncated cone-shaped.

[0013] Preferably, a silicone bonding pad is provided on the top surface of the transparent incubator, and the escape-proof cover is attached to the silicone bonding pad; This feature ensures a tight seal between the escape-proof cover and the transparent incubator, making it less likely for Hirudo seedlings to escape.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a honeycomb partition plate inserted into a rectangular frame, combined with a multi-layer detachable transparent cultivation box on a steel frame. The honeycomb holes provide independent activity space for Hirudo seedlings, avoiding the problems of fighting for food and biting caused by traditional mixed rearing or straight plate division. The multi-layer design enables the seedlings to be cultivated in batches, while the transparent box makes it easy to observe the growth status of seedlings in different layers, thereby improving the survival rate of seedlings and adapting to large-scale cultivation.

[0015] 2. This utility model, by setting an inner support net at the bottom of the rectangular frame and a drain pipe on the side of the transparent cultivation box, allows seedling feces, residual feed and other impurities to fall to the bottom of the box through the inner support net. The manual valve can be opened to discharge the impurities through the drain pipe without turning the seedlings over. This solves the problems of cumbersome impurity cleaning and easy stress response in seedlings caused by traditional devices, and achieves the effect of simplifying maintenance operations and ensuring a clean cultivation environment.

[0016] 3. This utility model features an escape-proof cover plate covering the top of a transparent incubator, a silicone bonding pad on the top of the box, and positioning posts on the cover plate. The positioning posts ensure the cover plate is securely installed, the silicone bonding pad strengthens the seal to prevent escape, and the breathable barrier net ensures ventilation inside the box to avoid oxygen deficiency. At the same time, the transparent box allows for observation without opening it, achieving the effects of preventing escape, breathability, and convenient observation. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a layered cultivation and observation device for Hirudo nipponia seedlings, including a steel frame 1. Multiple inner support blocks 10 are fixedly installed on the inner sides of the left and right side plates of the steel frame 1. A transparent cultivation box 2 is detachably installed on two symmetrical inner support blocks 10. The transparent cultivation box 2 has a transparent box structure, and the staff can directly observe the activity, feeding and growth status of the seedlings in the box without opening the anti-escape cover 25.

[0020] like Figure 1 and Figure 2 As shown, the inner support pad 10 has a central hole 11, and the bottom surface of the transparent incubator 2 is fixedly installed with a plug-in protrusion 20. The plug-in protrusion 20 and the central hole 11 are plugged in and matched, so that the transparent incubator 2 and the steel frame 1 can be assembled without complicated tools. At the same time, it is convenient for subsequent disassembly, maintenance or adjustment of the number of incubator layers, and improves the flexibility of device assembly.

[0021] In this embodiment, a rectangular frame 23 is inserted into the transparent incubation box 2. An inner support net 231 is provided at the bottom of the rectangular frame 23. The distance between the inner support net 231 and the bottom wall of the transparent incubation box 2 is between 10mm and 18mm. The leech seedlings are located above the inner support net 231. The inner support net 231 intercepts the leech seedlings, and impurities fall down along the inner support net 231 to the bottom of the inner support net 231. Feces, residual feed and other impurities fall through the mesh to the bottom of the box, realizing the physical separation of seedlings and impurities, reducing the impact of impurities on seedling growth and reducing the risk of water quality deterioration. In addition, the rectangular frame 23 and the inner support net 231 can be removed for cleaning operations later.

[0022] like Figure 4 As shown, a honeycomb partition plate 24 is inserted and fitted inside the rectangular frame 23. The honeycomb partition plate 24 has a honeycomb-shaped structure and is a transparent plate structure. Each honeycomb cell can accommodate a single or a small number of seedlings, providing the seedlings with independent space for activity and feeding, avoiding the problems of seedlings fighting for food and biting each other in traditional mixed breeding. At the same time, the honeycomb structure does not obstruct the view, making it easy to monitor the growth status of the seedlings.

[0023] Specifically, the top surface of the transparent incubator 2 is covered with an escape-proof cover 25, and a breathable barrier net 251 is set at the center of the escape-proof cover 25. The escape-proof cover 25 can prevent the seedlings from climbing out of the box, while the breathable barrier net 251 ensures air circulation inside and outside the box, avoiding oxygen deficiency in the box and causing the seedlings to die, thus achieving the dual requirements of escape prevention and ventilation.

[0024] Furthermore, handles 21 are fixedly installed on both the front and rear sides of the transparent incubation box 2. The cross-section of the handles 21 is arc-shaped, allowing staff to easily move or pull the transparent incubation box 2 through the handles 21, avoiding slippage of the box during handling and thus preventing damage to the seedlings, reducing the difficulty of operation and improving ease of use.

[0025] like Figure 3 As shown, a drain pipe 22 is fixedly installed on the side of the transparent incubation box 2, and a manual valve 221 is fixedly installed on the drain pipe 22. When impurities accumulate below the inner support net 231, the manual valve 221 can be opened without opening the box, and the impurities can be quickly discharged through the drain pipe 22, reducing interference with the seedling growth environment and ensuring a clean cultivation environment.

[0026] In addition, handle grooves 232 are provided on the inner walls of the left and right side plates of the rectangular frame 23. The depth of the handle grooves 232 is between 5mm and 12mm. The staff can insert their fingers into the handle grooves 232 to easily remove the rectangular frame 23 from the transparent incubator 2, which facilitates the replacement of the inner support net 231 or the cleaning of the rectangular frame 23, simplifying maintenance operations.

[0027] It is worth noting that each of the four corners of the transparent incubator 2 is provided with a plug-in hole 26, and each of the four corners of the escape-proof cover 25 is fixedly installed with a positioning post 252. The positioning post 252 is plugged into the plug-in hole 26. The length of the positioning post 252 is between 1cm and 1.5cm, and the bottom of the positioning post 252 is truncated cone-shaped. The truncated cone-shaped bottom facilitates the quick insertion of the positioning post 252 into the plug-in hole 26, while limiting the lateral displacement of the escape-proof cover 25, ensuring that the cover is installed accurately and stably.

[0028] It is worth noting that a silicone bonding pad 27 is provided on the top surface of the transparent incubator 2. The escape-proof cover 25 is attached to the silicone bonding pad 27. When the escape-proof cover 25 is attached to the silicone bonding pad 27, it can fill the gap between the cover and the box body, enhance the sealing effect, and prevent the leech seedlings from escaping from the gap. At the same time, the silicone material is soft and will not damage the edge of the box body when the cover is pressed.

[0029] When using the multi-layer cultivation and observation device for Hirudo nipponia seedlings of this utility model, the insertion protrusion 20 on the bottom surface of the transparent cultivation box 2 is aligned with the center hole 11 of the inner support pad 10 of the steel frame 1 and inserted to complete the assembly of the multi-layer cultivation box; the handle groove 232 of the rectangular frame 23 is inserted into the transparent cultivation box 2, and then the honeycomb partition plate 24 is inserted into the rectangular frame 23; finally, the positioning post 252 of the anti-escape cover 25 is inserted into the box body insertion hole 26 so that the cover plate fits the silicone bonding pad 27. Open the escape-proof cover 25, place the Hirudo seedlings into the independent holes of the honeycomb partition plate 24, add an appropriate amount of cultivation water, and close the cover tightly; observe the seedlings' condition through the transparent box to ensure that the ventilation barrier 251 is functioning properly; Regularly observe the seedling growth through the transparent incubator 2. When impurities accumulate, open the manual valve 221 of the drain pipe 22 to drain the sewage. When it is necessary to clean or replace the inner support net 231, remove the rectangular frame 23 through the handle groove 232 and then perform replacement or internal cleaning operations.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
