Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a device for hatching fertilized squid eggs and separating larvae. Background Technology
[0002] In the field of marine organism breeding, squid aquaculture has attracted much attention due to its high economic value. However, there are still many technical difficulties in the process of hatching fertilized squid eggs and separating larvae. At present, traditional squid egg hatching mostly adopts open culture ponds. After the fertilized eggs hatch and break through the membrane into larvae, the traditional method requires manual separation of larvae from unhatched eggs or hatching debris. The operation is cumbersome and can easily cause mechanical damage to the larvae. The separation efficiency is low and it is easy to cause stress and ink spraying in the larvae, which is not conducive to subsequent cultivation. In addition, the existing equipment lacks an integrated design for the hatching stage and the larvae separation stage, and cannot realize automated or semi-automated operation from hatching to separation. This increases labor costs and management difficulty, and makes it difficult to meet the needs of large-scale and standardized squid breeding. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a squid fertilized egg hatching and larval separation device, which enables the squid fertilized eggs to hatch smoothly in the device and automatically separates the larvae from the egg membrane and remains. The separation efficiency is higher, the mechanical damage to the squid larvae during the separation process is reduced, and the subsequent cultivation of squid is facilitated. It can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for hatching fertilized squid eggs and separating larvae, including a larvae collection basket;
[0005] Larval Collection Basket: This basket contains a fertilized egg hatching basket. The upper end of the fertilized egg hatching basket has a connecting mechanism that engages with the upper end of the larval collection basket. The larval collection basket has evenly spaced square perforated slots around its frame and bottom. The width of these square perforated slots is smaller than the width of newly hatched squid larvae. The fertilized egg hatching basket has evenly spaced elongated perforated slots around its frame and bottom. The width of these elongated perforated slots is smaller than the diameter of the squid eggs but larger than the width of newly hatched squid larvae. The difference in the width of the perforated slots on the surfaces of the larval collection basket and the fertilized egg hatching basket allows the fertilized squid eggs to hatch smoothly within the device and automatically separates the larvae from the egg membrane and remains. This results in higher separation efficiency, reduces mechanical damage to the squid larvae during separation, improves the hatching rate of the fertilized eggs and the survival rate of the larvae, and facilitates subsequent squid rearing. T-shaped plates and insert plates are inserted sequentially into the T-shaped holes to quickly and securely connect the larval collection basket and the fertilized egg hatching basket, reducing the assembly time required for the hatching device and making it more convenient to use.
[0006] Furthermore, the connecting mechanism includes a foam ring, a T-shaped hole, and a T-shaped plate. The foam ring is located on the upper outer side of the fertilized egg incubation basket. T-shaped holes are provided at both ends of the front surface of the foam ring. T-shaped plates are slidably connected inside the T-shaped holes. The lower ends of the two T-shaped plates are connected to the larvae collection basket, thus connecting the larvae collection basket and the fertilized egg incubation basket.
[0007] Furthermore, the connecting mechanism also includes insert plates, which are inserted into the interior of the T-shaped holes. The rear end of the upper surface of the insert plates is inclined. The insert plates are installed in conjunction with the cross plate of the T-shaped plate to restrict the position of the T-shaped plate.
[0008] Furthermore, the connecting mechanism also includes a connecting plate, which is disposed between the lower surfaces of the two T-shaped plates. The larvae collection basket is disposed on the lower surface of the connecting plate. After the insert plates are inserted, the tight contact between the connecting plate and the lower surface of the foam ring improves the tightness of the connection between the larvae collection basket and the fertilized egg incubation basket.
[0009] Furthermore, the connecting mechanism also includes a rear sealing plate, which is provided at the rear end of the upper surface of the connecting plate. The rear sealing plate is installed in conjunction with the rear end of the T-hole to seal the rear end of the T-hole.
[0010] Furthermore, the connecting mechanism also includes a front sealing plate, which is disposed between the front ends of the four insert plates. The front sealing plate is installed in conjunction with the front end of the T-hole to block the front end of the T-hole.
[0011] Furthermore, the T-shaped plate, connecting plate, rear sealing plate, and front sealing plate are all made of plastic, which reduces the weight of the overall device and makes it easier for the overall device to float on the water surface.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This squid fertilized egg incubation and larval separation device has the following advantages:
[0013] 1. By using different widths of the perforated grooves on the surfaces of the larvae collection basket and the fertilized egg incubation basket, the fertilized squid eggs can be successfully incubated in the device and the larvae, egg membranes and remains can be automatically separated. The separation efficiency is higher, the mechanical damage to the squid larvae during the separation process is reduced, the hatching rate of the fertilized squid eggs and the survival rate of the larvae are improved, and the subsequent breeding of squid is facilitated.
[0014] 2. By inserting the T-shaped plate and the insert plate into the T-shaped hole in sequence, the larvae collection basket and the fertilized egg incubation basket can be quickly and firmly connected, reducing the time required to assemble the incubation device and making it more convenient to use.

[0020] 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.
[0021] Please see Figure 1-4 This embodiment provides a technical solution: a device for hatching fertilized squid eggs and separating larvae, including a larvae collection basket 3;
[0022] Larval Collection Basket 3: This basket contains a fertilized egg hatching basket 1. The upper end of the fertilized egg hatching basket 1 is equipped with a connecting mechanism 2, which engages with the upper end of the larval collection basket 3. The frame of the larval collection basket 3 has evenly distributed square perforated slots around its perimeter and bottom. The width of these square perforated slots is smaller than the width of newly hatched squid larvae. The frame of the fertilized egg hatching basket 1 has evenly distributed elongated perforated slots around its perimeter and bottom. The width of these elongated perforated slots is smaller than the diameter of the squid eggs but larger than the width of newly hatched squid larvae. During hatching, the fertilized squid eggs are placed inside the fertilized egg hatching basket 1. Due to the elongated perforated slots on the surface of the fertilized egg hatching basket 1, the fertilized eggs will not leak out. Water and airflow can fully enter the fertilized egg hatching basket 1 through the elongated perforated slots. The exchange of water and air maintains the water's freshness and provides sufficient oxygen for the hatching of squid fertilized eggs. When the squid fertilized eggs have been hatching for approximately 20 days, and the larvae are about to hatch, the larval collection basket 3 is placed over the fertilized egg hatching basket 1 from bottom to top. The hatched squid larvae swim out through the long, hollowed-out groove of the fertilized egg hatching basket 1 and enter the larval collection basket 3. Because the width of the square hollowed-out groove in the larval collection basket 3 is smaller than the width of the squid larvae, the larvae will gather inside the larval collection basket 3, achieving automatic separation of the larvae from the egg membrane debris. The connecting mechanism 2 includes a foam ring 21, T-shaped holes 22, and a T-shaped plate 26. The foam ring 21 is located on the upper outer surface of the fertilized egg hatching basket 1, and T-shaped holes 22 are provided on both the left and right ends of the front surface of the foam ring 21. T-shaped plates 26 are slidably connected inside the T-shaped holes 22. The lower ends of the two T-shaped plates 26 are connected to the larvae collection basket 3. The larvae collection basket 3 is placed over the fertilized egg hatching basket 1 from bottom to top. The T-shaped plates 26 press against the foam ring 21, causing the foam ring 21 to deform. The T-shaped plates 26 can then enter the interior of the T-shaped holes 22 from bottom to top, achieving the snap-fit between the larvae collection basket 3 and the fertilized egg hatching basket 1. The connecting mechanism 2 also includes insert plates 25, which are inserted into the interior of the T-shaped holes 22. The rear ends of the upper surfaces of the insert plates 25 are all inclined. The insert plates 25 are installed in conjunction with the horizontal plates of the T-shaped plates 26. The inclined rear ends of the insert plates 25 allow them to be inserted more smoothly between the lower surface of the horizontal plate of the T-shaped plate 26 and the bottom wall of the T-shaped hole 22. With the filling of 5, the T-shaped plate 26 moves upward until it contacts the top wall of the T-shaped hole 22. The T-shaped plate 26 and the T-shaped hole 22 are in an interference fit, which restricts the position of the T-shaped plate 26. The connecting mechanism 2 also includes a connecting plate 27, which is set between the lower surfaces of the two T-shaped plates 26. The larvae collection basket 3 is set on the lower surface of the connecting plate 27. When the insert plate 25 pushes the T-shaped plate 26 upward, the T-shaped plate 26 pulls the connecting plate 27 upward simultaneously, so that the upper surface of the connecting plate 27 is tightly fitted with the lower surface of the foam ring 21, reducing the gap at the connection between the larvae collection basket 3 and the fertilized egg hatching basket 1. The connecting mechanism 2 also includes a rear sealing plate 23. The rear sealing plate 23 is provided at the rear end of the upper surface of the connecting plate 27. The rear sealing plate 23 is installed in conjunction with the rear end of the T-shaped hole 22.The rear end of the T-hole 22 is sealed. The connecting mechanism 2 also includes a front sealing plate 24, which is positioned between the front ends of the four insert plates 25. The front sealing plate 24 is installed in conjunction with the front end of the T-hole 22 to seal the front end of the T-hole 22, facilitating the simultaneous movement of the four insert plates 25. The T-hole 26, connecting plate 27, rear sealing plate 23, and front sealing plate 24 are all made of plastic and lightweight materials, reducing the overall weight of the device and allowing it to float on the water.
[0023] The working principle of the squid fertilized egg hatching and larval separation device provided by this utility model is as follows: During use, the squid fertilized eggs are placed inside the fertilized egg hatching basket 1. After the hatching basket 1 is placed in water, the buoyancy of the water on the foam ring 21 keeps the hatching basket 1 floating on the water surface. Simultaneously, due to the elongated perforated grooves on the surface of the hatching basket 1, the fertilized eggs will not leak out. Water and air can fully enter the hatching basket 1 through the elongated perforated grooves, achieving water and air exchange and maintaining the water's freshness and sufficient oxygen requirements for the hatching of the squid fertilized eggs. When the squid fertilized eggs have hatched for approximately 20 days and the larvae are about to hatch, the larval collection basket 3 is placed over the hatching basket 1 from bottom to top. During the connection process, the foam ring 21 is first deformed by the pressure of the T-shaped plate 26, allowing the T-shaped plate 26 to be lowered from below. The plate enters the interior of the T-hole 22, and then the front sealing plate 24 drives the four insert plates 25 to move synchronously from front to back. This causes the insert plates 25 to be inserted between the lower surface of the horizontal plate of the T-plate 26 and the bottom wall of the T-hole 22. With the filling effect of the insert plates 25, the T-plate 26 moves upward until it contacts the top wall of the T-hole 22. The T-plate 26 and the T-hole 22 are in an interference fit, restricting the position of the T-plate 26. Simultaneously, the upper surface of the connecting plate 27 is pulled against the bubble... The lower surface of the foam ring 21 fits tightly, reducing the gap at the connection between the larvae collection basket 3 and the fertilized egg hatching basket 1, thus completing the connection between the larvae collection basket 3 and the fertilized egg hatching basket 1. The hatched squid larvae swim out from the long, hollowed-out groove of the fertilized egg hatching basket 1 and enter the interior of the larvae collection basket 3. Since the width of the square hollowed-out groove of the larvae collection basket 3 is smaller than the width of the squid larvae, the squid larvae will gather in the larvae collection basket 3, realizing the automatic separation of the squid larvae from the egg membrane remains.
[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
