Description

Technical Field

[0001] This utility model relates to the field of eel hatching technology, specifically to a batch centralized hatching device for eels. Background Technology

[0002] The swamp eel, also known as the yellow eel, is a type of fish that undergoes sex reversal. It is one of the important freshwater special economic fish species in China. Swamp eels have high production value and great market potential, and the supply of products cannot meet the demand. Therefore, artificial breeding is adopted. In wild swamp eel eggs, during the incubation process, the eggs are covered by foam expelled by the parent fish and float on the water surface to incubate. In the artificial breeding process of swamp eels, if the eggs accumulate in the water during incubation, a large number of eel eggs will die.

[0003] In actual breeding, the common hatching method involves placing fertilized eggs in a simple hatching frame and then incubating them with a micro-flow water system. These frames are typically made of wood, metal, or plastic with a mesh screen. However, such frames often result in the fertilized eggs piling up and overlapping due to the lack of spacing between them and the movement of the micro-flow water or oxygen bubbles. Furthermore, they are inconvenient for large-scale centralized hatching, ultimately leading to a low hatching rate for eels. Therefore, we propose a batch centralized hatching device for eels. Utility Model Content

[0004] To address the shortcomings of existing hatching frames, which tend to overlap and are inconvenient for batch hatching, resulting in low hatching rates for eels, this invention provides a batch centralized hatching device for eels. This device allows fertilized eggs to continuously suspend and settle in the water, ensuring sufficient dissolved oxygen and effectively improving the hatching rate of eels, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A batch centralized hatching device for loach includes an installation frame, with multiple support plates equidistantly connected inside the installation frame. Each support plate has a support frame directly below it, and several limiting sleeves are connected inside the support frame. The cross-section of the limiting sleeves is a trumpet shape with the opening facing upwards. A rotating shaft is rotatably connected to the top center of the support plate. A sleeve is coaxially and tightly connected to the outside of the rotating shaft, and a motor is tightly fastened to the top of the rotating shaft. Symmetrically open through holes are provided on the top of the support plate, and a guide wheel is rotatably connected to the side of the through hole closest to the motor. A traction rope is symmetrically connected to the top of the support frame. The end of the traction rope passes through the through hole and wraps around to the top of the guide wheel, and the end of the traction rope is wound around the outer wall of the connecting sleeve and fixedly connected to it.

[0006] Optionally, the limiting sleeves are arranged in several rows, and each row of limiting sleeves has symmetrical connecting plates on both sides. Adjacent connecting plates are fixedly connected, and the connecting plates at the ends are fastened to the inner wall of the support frame.

[0007] Optionally, an anti-slip pad may be fitted onto the inner wall of the sleeve.

[0008] Optionally, a connecting frame is symmetrically provided on the top of the support frame, and an annular seat is fixedly connected to the top of each connecting frame to fix one end of the traction rope to the annular seat.

[0009] Optionally, guide seats are fixedly connected to both ends of the support frame, and guide rods are vertically connected to the bottom of the support plate, with the guide seats and guide rods slidably connected.

[0010] Optionally, both ends of the connecting sleeve are coaxially connected to limit plates, the diameter of which is larger than that of the connecting sleeve.

[0011] Optionally, connecting seats are symmetrically provided on the outer wall of the connecting sleeve, and the other end of the traction rope is fixedly connected to the connecting seats.

[0012] Optionally, the guide wheel is connected to the support plate via a hinged seat.

[0013] Optionally, the bottom of the mounting frame is symmetrically connected with multiple support vertical bars.

[0014] Compared with the prior art, this utility model uses a motor to drive the traction rope to move up and down on the connecting sleeve, thereby realizing the lifting and sliding of the support frame. The breeding bucket containing fertilized eggs is placed in the limiting sleeve. During the sliding process, the fertilized eggs can be continuously suspended and settled in the water, ensuring sufficient dissolved oxygen, preventing the fertilized eggs from clumping and getting moldy, and promoting embryo development. This utility model is not only simple in structure, but also effectively improves the hatching rate of eels. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a technical solution: a batch centralized hatching device for slugs, including an installation frame 2. Multiple supporting vertical rods 15 are symmetrically connected to the bottom of the installation frame 2. Multiple supporting plates 1 are equidistantly connected inside the installation frame 2. A supporting frame 7 is provided directly below each supporting plate 1. Several limiting sleeves 11 are connected inside the supporting frame 7. The limiting sleeves 11 are arranged in several rows, and connecting plates 8 are symmetrically provided on both sides of each row of limiting sleeves 11. Adjacent connecting plates 8 are fixedly connected. The connecting plates 8 at the ends are fastened to the inner wall of the supporting frame 7. Under the fastening action of the connecting plates 8, the stability of the limiting sleeves 11 connected inside the installation frame 2 can be effectively improved, ensuring the stable placement of the breeding tanks placed inside the limiting sleeves 11, thereby protecting the eggs inside the tanks. At the same time, it also facilitates the placement and removal of the breeding tanks inside the limiting sleeves 11. The structure is simple and highly practical.

[0023] Meanwhile, to further improve the stability of the breeding tank placed inside the limiting sleeve 11, the cross-section of the limiting sleeve 11 is a funnel shape with the opening facing upwards, so that the tank can sit stably inside the limiting sleeve 11. An anti-slip pad 20 is tightly attached to the inner wall of the limiting sleeve 11, which greatly increases the friction between the inner wall of the limiting sleeve 11 and the outer wall of the breeding tank, further enhancing the stability.

[0024] like Figure 3 , 4As shown, a rotating shaft 18 is rotatably connected to the top center of the support plate 1, and a motor 14 is fastened to the top of the rotating shaft 18. A sleeve 16 is coaxially fastened to the outside of the rotating shaft 18. A through hole 12 is symmetrically opened on the top of the support plate 1, and a guide wheel 3 is rotatably connected to the side of the through hole 12 close to the motor 14. The guide wheel 3 is connected to the support plate 1 through a hinge seat 6. A traction rope 4 is symmetrically connected to the top of the support frame 7. A connecting frame 5 is symmetrically arranged on the top of the support frame 7. A ring seat 19 is fixedly connected to the top of each connecting frame 5, and one end of the traction rope 4 is fixedly connected to the ring seat 19.

[0025] Meanwhile, the end of the traction rope 4 is passed through the through hole 12 and wound to the top of the guide wheel 3. The end of the traction rope 4 is also wound around the outer wall of the connecting sleeve 16 and fixedly connected thereto. Both ends of the connecting sleeve 16 are coaxially connected to the limiting plate 13. The diameter of the limiting plate 13 is larger than the diameter of the connecting sleeve 16, which can limit the traction rope 4 wound on the connecting sleeve 16 to ensure the normal use of the traction rope 4. In order to improve the stability of the connection at the end of the traction rope 4, the connecting seat 17 is symmetrically provided on the outer wall of the connecting sleeve 16, and the other end of the traction rope 4 is fixedly connected to the connecting seat 17.

[0026] In summary, this centralized hatching equipment for swamp eels, when in use, can achieve the raising and lowering of the traction rope 4 on the connecting sleeve 16 under the drive of the motor 14, thereby driving the support frame 7 and the breeding tank located on it to slide up and down. During the sliding process, the breeding tank is controlled to rise slowly and then fall rapidly. This repeated operation allows the fertilized eggs to continuously suspend and sink in the water, ensuring sufficient dissolved oxygen, preventing the fertilized eggs from clumping and becoming moldy, and promoting embryo development. At the same time, in order to improve the stable raising and lowering sliding of the support frame 7, guide seats 10 are fixedly connected to both ends of the support frame 7, and guide rods 9 are vertically connected to the bottom of the support plate 1. The guide seats 10 and guide rods 9 are slidably connected.
