Description

Technical Field

[0001] This utility model belongs to the field of fish fry hatching technology, specifically a cultivation unit for early hatching and cultivation of fish fry. Background Technology

[0002] Early hatching and rearing of fish fry is a fundamental step in the aquaculture industry. The water flow control capability of the hatching device directly affects the hatching rate, survival rate, and subsequent growth potential of the fish fry, and its technical rationality has a crucial impact on the economic benefits of the aquaculture industry. Currently, the mainstream fish fry hatching devices in the industry are mainly divided into two categories: one type uses a simple water tank structure, creating a circular water flow by adjusting the direction of the water inlet nozzle at the top; the other type has multiple water inlets in the same direction at the bottom of the water tank, forming a circular flow environment by means of water jet force.

[0003] However, both types of traditional hatching devices suffer from core technological flaws: due to insufficient design in the water flow generation method, the resulting annular water flow is extremely unstable, prone to turbulence and uneven flow velocity. This unstable water environment directly leads to an unbalanced distribution of fish fry during hatching, with excessive aggregation and stacking of fry in some areas. This not only causes localized oxygen deficiency but may also result in injury or even death due to squeezing and collisions between fry, severely restricting hatching efficiency and improving fry survival rates. Furthermore, the unstable water flow cannot provide a suitable environment for fry movement, hindering the cultivation of fry vitality and further affecting their growth performance in subsequent rearing stages.

[0004] Therefore, this utility model provides a cultivation unit for early hatching and cultivation of fish fry. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that the unstable water flow environment mentioned in the background technology directly leads to an unbalanced distribution of fish fry during the hatching process, with excessive aggregation and stacking of fish fry in some areas, which not only causes localized insufficient dissolved oxygen but may also cause damage or even death due to squeezing and collision between fish fry, a cultivation unit for early hatching and cultivation of fish fry is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A cultivation unit for early hatching and cultivation of fish fry, comprising a hatching tank; a rotating mechanism is provided at the bottom of the inner wall of the hatching tank, and an agitating mechanism is provided on the inner wall of the rotating mechanism; a driving mechanism is provided at the top of the hatching tank, and a docking mechanism is provided at the top of the agitating blades; a clamping mechanism is provided on one side of the top of the fixed upright; the rotating mechanism includes a rotating ring, a fixed upright, and a dovetail groove; the rotating ring is rotatably installed at the bottom of the inner wall of the hatching tank; several sets of fixed uprights are provided, and these sets are fixedly installed in a ring on the top of the rotating ring; a dovetail groove is provided on the side of the fixed upright away from the hatching tank; the combined use of the rotating ring, the fixed upright, and the dovetail groove can provide stable support for the agitating mechanism and can rotate synchronously with the toothed ring, thereby reducing the pressure on the agitating blades during rotation.

[0007] Preferably, the agitation mechanism includes trapezoidal rods, agitating blades, and through grooves. Several sets of trapezoidal rods are provided, and these sets of trapezoidal rods are slidably installed on the inner wall of the fixed upright through the opening of dovetail grooves. The side of the trapezoidal rod away from the fixed upright is fixedly installed with the agitating blades. The surface of the agitating blades is provided with through grooves. In this scheme, the cooperation of the trapezoidal rods and agitating blades can continuously agitate the water inside the hatching tank as the fixed upright rotates, so that the water flow can be uniform. Furthermore, when the agitating blades are damaged, they can be removed separately from the inner wall of the fixed upright without replacing the entire assembly. The opening of the through grooves can reduce the resistance when the agitating blades rotate.

[0008] Preferably, the driving mechanism includes a gear ring, a motor, and drive teeth. The gear ring is rotatably mounted on the top of the hatching tank, the motor is fixedly mounted on one side of the surface of the hatching tank, the output end of the motor is fixedly mounted to the drive teeth, and the drive teeth mesh with the gear ring. In this scheme, the combined use of the gear ring, the motor, and the drive teeth can provide the main driving force for the rotation of the stirring blades and the fixed uprights, and can connect multiple sets of stirring blades to each other to achieve even distribution of torque during rotation.

[0009] Preferably, the docking mechanism includes a first insert plate, an insert rod, and a first slot. The first insert plate is fixedly installed on the top of the agitator blade, and the insert rod is fixedly installed on the side of the top of the agitator blade near the trapezoidal rod. The first slot is opened on the surface of the toothed ring and located on the side near the multiple sets of agitator blades. The first insert plate and the insert rod are movably inserted into the toothed ring through the opening of the first slot. In this scheme, the cooperation of the first insert plate, the insert rod, and the first slot enables the agitator blade and the toothed ring to be quickly inserted and can balance the pressure, avoiding deformation of the agitator blade when agitating the water flow.

[0010] Preferably, the clamping mechanism includes a second insert plate, a locking block, and a second slot. The second insert plate is fixedly installed on the top of the fixed upright on the side away from the trapezoidal rod. The top of the second insert plate is rotatably installed with the locking block. The second slot is opened on the surface of the toothed ring near the second insert plate. The second insert plate and the locking block are movably inserted into the inner wall of the toothed ring through the opening of the second slot. In this scheme, the cooperation of the second insert plate, the locking block, and the second slot enables the fixed upright to be clamped with the toothed ring, thereby distributing the torque on the stirring blades when the toothed ring rotates to prevent deformation. Furthermore, the locking block can be rotated to firmly clamp the second insert plate into the inner wall of the toothed ring.

[0011] Preferably, an isolation net is fixedly installed on the inner wall of the toothed ring. In this design, the isolation net can isolate the fish fry from the agitator blades, thereby preventing the fish fry from being injured when the agitator blades rotate, and the isolation net does not affect the normal flow of water.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The cultivation unit for early hatching and rearing of fish fry described in this utility model, through the arrangement of a rotating ring, a fixed upright, a dovetail groove, a trapezoidal rod, a stirring blade, and a through groove, enables the rotating ring, the fixed upright, and the dovetail groove to work together to provide stable support for the stirring mechanism and to rotate synchronously with the toothed ring, thereby reducing the pressure on the stirring blade during rotation. The trapezoidal rod and the stirring blade work together to continuously stir the water inside the hatching tank as the fixed upright rotates, thereby enabling the water flow to be uniform. Furthermore, when the stirring blade is damaged, it can be disassembled separately from the inner wall of the fixed upright without replacing the entire assembly. The through groove reduces the resistance when the stirring blade rotates.

[0014] 2. The cultivation unit for early hatching and cultivation of fish fry described in this utility model, through the arrangement of a toothed ring, a motor, a drive tooth, a first insert plate, an insert rod, and a first slot, enables the toothed ring, motor, and drive tooth to work together to provide the main driving force for the rotation of the stirring blades and the fixed upright, and can connect multiple sets of stirring blades to each other to achieve even distribution of torque during rotation. The cooperation of the first insert plate, insert rod, and first slot enables the stirring blades to be quickly inserted into the toothed ring and can balance the pressure, preventing the stirring blades from deforming when stirring the water flow.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6As shown in the embodiment of this utility model, a cultivation unit for early hatching and cultivation of fish fry includes a hatching tank 1; a rotating mechanism 2 is provided at the bottom of the inner wall of the hatching tank 1, and an agitating mechanism 3 is provided on the inner wall of the rotating mechanism 2; a driving mechanism 4 is provided at the top of the hatching tank 1, and a docking mechanism 5 is provided at the top of the agitating blades 32; a clamping mechanism 6 is provided on one side of the top of the fixed upright 22; the rotating mechanism 2 includes a rotating ring 21, a fixed upright 22, and a dovetail groove 23, the rotating ring 21 is rotatably installed at the bottom of the inner wall of the hatching tank 1, and the fixed upright 22 is provided with a... The dry assembly consists of several sets of fixed uprights 22, which are fixedly installed in a ring on the top of the rotating ring 21. A dovetail groove 23 is provided on the side of the fixed uprights 22 away from the incubation tank 1. The stirring mechanism 3 includes trapezoidal rods 31, stirring blades 32, and through grooves 33. Several sets of trapezoidal rods 31 are provided, and these sets of trapezoidal rods 31 are slidably installed on the inner wall of the fixed uprights 22 through the opening of the dovetail grooves 23. The side of the trapezoidal rods 31 away from the fixed uprights 22 is fixedly installed with the stirring blades 32. The surface of the stirring blades 32 has through grooves 33. The drive mechanism 4 includes a gear ring 41, a motor 42, and... A drive gear 43 and a gear ring 41 are rotatably mounted on the top of the incubation tank 1. A motor 42 is fixedly mounted on one side of the surface of the incubation tank 1. The output end of the motor 42 is fixedly mounted to the drive gear 43. The drive gear 43 meshes with the gear ring 41. The docking mechanism 5 includes a first insert plate 51, an insert rod 52, and a first slot 53. The first insert plate 51 is fixedly mounted on the top of the stirring blade 32. The insert rod 52 is fixedly mounted on the top of the stirring blade 32 near the trapezoidal rod 31. The first slot 53 is opened on the surface of the gear ring 41 and is located on the side near the multiple sets of stirring blades 32. The insert plate 51 and the insert rod 52 are movably inserted into the toothed ring 41 through the opening of the first slot 53. The clamping mechanism 6 includes a second insert plate 61, a locking block 62, and a second slot 63. The second insert plate 61 is fixedly installed on the top of the fixed upright 22 away from the trapezoidal rod 31. The top of the second insert plate 61 is rotatably installed with the locking block 62. The second slot 63 is opened on the surface of the toothed ring 41 near the second insert plate 61. The second insert plate 61 and the locking block 62 are movably inserted into the inner wall of the toothed ring 41 through the opening of the second slot 63. An isolation net 70 is fixedly installed on the inner wall of the toothed ring 41.

[0027] like Figures 1 to 6As shown, the combined use of the rotating ring 21, fixed upright 22, and dovetail groove 23 provides stable support for the agitation mechanism 3 and can rotate synchronously with the gear ring 41, thereby reducing the pressure on the agitator blade 32 during rotation. The combined use of the trapezoidal rod 31 and the agitator blade 32 can continuously agitate the water inside the hatching tank 1 as the fixed upright 22 rotates, thus ensuring a uniform water flow. When the agitator blade 32 is damaged, it can be individually removed from the inner wall of the fixed upright 22 without replacing the entire assembly. The opening of the through groove 33 reduces the resistance during the rotation of the agitator blade 32. The combined use of the gear ring 41, motor 42, and drive gear 43 provides the main driving force for the rotation of the agitator blade 32 and the fixed upright 22, and can connect multiple sets of agitator blades 32 to each other. The first insert plate 51, insert rod 52, and first slot 53 work together to distribute the torque during rotation, allowing the agitator blade 32 to be quickly inserted into the toothed ring 41 and to balance the pressure, preventing the agitator blade 32 from deforming when agitating the water. The second insert plate 61, locking block 62, and second slot 63 work together to lock the fixed upright 22 into the toothed ring 41, thereby distributing the torque on the agitator blade 32 when the toothed ring 41 rotates, preventing its deformation. The locking block 62 can be rotated to firmly lock the second insert plate 61 into the inner wall of the toothed ring 41. The isolation net 70 can isolate the fish fry from the agitator blade 32, preventing the fish fry from being injured when the agitator blade 32 rotates, and the isolation net 70 does not affect the normal flow of water.

[0028] Working Principle: During operation, the hatching tank 1 is first placed on a flat surface. The user then fills the tank with water, followed by placing the fish fry into the isolation net 70 inside the tank. Next, the motor 42 is started, driving the drive gear 43 to rotate. The rotation of the drive gear 43 drives the gear ring 41 to rotate. The rotation of the gear ring 41, through the first insert plate 51, the insert rod 52, and the second insert plate 61, drives the stirring blades 32 and the fixed support rod 22 to rotate. The rotation of multiple stirring blades 32 continuously agitates the water flow inside the hatching tank 1, ensuring water circulation and preventing the fish fry from piling up. Simultaneously, the isolation net 70 separates the fish fry from the stirring blades 32, preventing injury during rotation. If the stirring blades 32 become damaged and need replacement, the user can rotate them sequentially. The user aligns the locking block 62 with the second insert plate 61, then pulls the toothed ring 41 upwards to remove it. Next, the user pulls the damaged agitator blade 32 upwards, allowing the trapezoidal rod 31 to slide inside the fixed upright 22, thus facilitating its removal and replacement. The user can also disassemble and clean the agitator blade 32 using the above steps. When installation is complete, the user first picks up the toothed ring 41, then aligns the first slot 53 with the insert rod 52 and the first insert plate 51, while simultaneously aligning the second slot 63 with the second insert plate 61. The blades are then inserted downwards, ensuring a stable connection between the multiple agitator blades 32 and the toothed ring 41. The user then rotates the locking block 62, causing it to interlock with the second insert plate 61, thus locking the second insert plate 61 and preventing it from being pulled out. This completes the disassembly and assembly process.
