Description

Technical Field

[0001] This utility model relates to the field of greenfin filefish, and more specifically, to a device for transferring juvenile greenfin filefish to a pond. Background Technology

[0002] The greenfin filefish is a warm-temperate, near-shore, bottom-dwelling fish with both ecological and economic value. It has an elongated, laterally compressed body without a lateral line, and its body color is mostly grayish-brown or dark brown. It gets its name from the green patches at the base of its pectoral fins and the green rays of its dorsal and anal fins. The greenfin filefish adapts to a salinity range of 20‰-35‰ and thrives in water temperatures of 18-28℃. It has a varied diet; juveniles mainly feed on zooplankton, small crustaceans, and algal detritus, while adults feed on benthic invertebrates. In recent years, due to overfishing of wild resources, its aquaculture industry has developed rapidly, with fry cultivation being a crucial link in the aquaculture chain.

[0003] The greenfin filefish fry need to be transferred between ponds during the rearing stage. The core reasons are: firstly, as the fry grow, the size difference between individuals increases, and transferring them between ponds is necessary to separate them by size, avoiding the survival rate drop caused by the survival of the weak. Secondly, the fry will produce uneaten feed, feces and other excrement during the rearing process, which can easily breed harmful bacteria and algae in the long run, leading to water quality deterioration. Transferring them between ponds can thoroughly clean the pollutants in the original rearing pond and improve the rearing environment. Currently, when transferring greenfin filefish fry between ponds, it is usually done manually using a net. However, the lifting speed and force direction of the net are unstable when operating manually, and the labor intensity of manual fishing and transferring is high. In addition, the dorsal fin of the greenfin filefish is a hard spine that can stand upright, which can easily get caught on the netting, requiring manual separation, which can cause damage to the fish and reduce the speed of transferring them between ponds. Therefore, a device for transferring juvenile greenfin filefish to a pond is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for transferring juvenile greenfin filefish to a pond, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for transferring juvenile greenfin filefish, comprising a movable plate, a support base fixedly mounted on the upper surface of the movable plate, a lifting plate provided on one side of the support base, a variable frequency motor fixedly mounted on the upper surface of the support base, a transmission screw fixedly mounted on the output end of the variable frequency motor, a lifting slider slidably connected to the inner wall of the support base, a threaded hole provided on the upper surface of the lifting slider, the outer surface of the transmission screw threadedly connected to the inner wall of the threaded hole, a connecting block fixedly connected to one side of the lifting slider, one side of the connecting block fixedly connected to one side of the lifting plate, a rotating component fixedly mounted on one side of the rotating component, a collection frame provided on one side of the rotating component, and a stainless steel filter screen fixedly embedded on the outer surface of the collection frame.

[0006] Preferably, the rotating assembly includes a geared motor fixedly mounted on one side of the lifting plate, a drive shaft fixedly mounted on the output end of the geared motor, a connecting plate fixedly mounted on one end of the drive shaft, one end of the connecting plate fixedly mounted to one side of the collecting frame, a reinforcing support plate fixedly mounted on one side of the lifting plate, a bearing ring fixedly embedded on one side of the reinforcing support plate, and the outer surface of the drive shaft fixedly connected to the inner ring of the bearing ring.

[0007] Preferably, the outer surface of the support base has two limiting sliding holes, and two limiting blocks are fixedly connected to one side of the connecting block. The outer surfaces of the two limiting blocks are slidably connected to the inner walls of the two limiting sliding holes respectively.

[0008] Preferably, two fixing blocks are fixedly installed on the upper surface of the support base, and the upper surfaces of the two fixing blocks are fixedly installed to the bottom end of the variable frequency motor.

[0009] Preferably, a bearing ring is fixedly embedded on the upper surface of the movable plate, and the outer surface of the bottom end of the transmission screw is fixedly connected to the inner ring of the bearing ring.

[0010] Preferably, a battery compartment is fixedly installed on the upper surface of the movable plate, a moving pusher is fixedly installed on the upper surface of the battery compartment, and two sets of omnidirectional wheels are fixedly installed on the bottom surface of the movable plate, and the omnidirectional wheels are equipped with a self-locking braking structure.

[0011] Preferably, the length of the collection frame is 60-80cm, the depth of the collection frame is 25-35cm, and the mesh diameter of the stainless steel filter is 0.8-1.2mm.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this device for transferring juvenile greenfin filefish to ponds uses a variable frequency motor to drive the rotation of a transmission screw. The screw, in conjunction with the threaded hole of the lifting slider, drives the connecting block and lifting plate to move up and down. This replaces the laborious manual operation of pulling a net. Furthermore, it can control the water level of the collection frame according to the depth of different ponds, avoiding the problem of inconsistent net height caused by improper force control during manual operation. During the transfer phase, a reduction motor drives the collection frame opening upwards, the variable frequency motor raises the height, and then the reduction motor reverses to achieve a smooth tilt, improving the efficiency of transferring fish to ponds and solving the problem of excessive labor intensity associated with manually transferring fish using nets.

[0013] Compared with existing technologies, this greenfin filefish juvenile transfer device, through the operation of a geared motor and its cooperation with the drive shaft and connecting plate, can drive the collection frame to rotate slowly, allowing the opening of the collection frame to open to one side. This allows the juveniles to enter the collection frame smoothly with the water flow, avoiding the collision of fish bodies caused by the forceful scooping of manual nets. In addition, the stainless steel filter screen can be adapted to the interception of juvenile body size, and due to the smooth nature of stainless steel, it solves the problem of the hard spines of the juvenile dorsal fin getting caught on traditional netting, eliminating the need for manual separation and reducing the risk of mucosal damage and scale loss.

[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. Example

[0021] As attached Figures 1-5 The device shown is for transferring juvenile greenfin filefish to a pond. It includes a movable plate 1, a support base 2 fixedly installed on the upper surface of the movable plate 1, a lifting plate 7 on one side of the support base 2, a variable frequency motor 3 fixedly installed on the upper surface of the support base 2, a transmission screw 4 fixedly installed at the output end of the variable frequency motor 3, a lifting slider 5 slidably connected to the inner wall of the support base 2, a threaded hole 18 opened on the upper surface of the lifting slider 5, the outer surface of the transmission screw 4 threadedly connected to the inner wall of the threaded hole 18, a connecting block 6 fixedly connected to one side of the lifting slider 5, one side of the connecting block 6 fixedly connected to one side of the lifting plate 7, a rotating component 8 fixedly installed on one side of the rotating component 8, a collection frame 9 provided on one side of the rotating component 8, a stainless steel filter screen 10 fixedly embedded on the outer surface of the collection frame 9, the length of the collection frame 9 is 60-80cm, the depth of the collection frame 9 is 25-35cm, and the mesh diameter of the stainless steel filter screen 10 is 0.8-1.2mm.

[0022] As can be seen from the above description, this utility model has the following beneficial effects: by utilizing the threaded engagement between the transmission screw 4 and the threaded hole 18 of the lifting slider 5, the connecting block 6 and the lifting plate 7 can be driven to move up and down, which will replace the laborious operation of manually lifting the net. In addition, the water entry height of the collection frame 9 can be controlled according to the different depths of the aquaculture pond, avoiding the problem of the net going up and down due to improper force control during manual operation. During the transfer stage, the reduction motor 802 drives the collection frame 9 to open upwards, the frequency converter motor 3 raises the height, and then drives the reduction motor 802 in the opposite direction to achieve smooth tilting, improve the pond transfer efficiency, and solve the problem of excessive labor intensity when manually transferring the net to the pond. Example

[0023] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figures 1-5As shown, in a preferred embodiment, the rotating assembly 8 includes a geared motor 802 fixedly mounted on one side of the lifting plate 7. The geared motor 802 is a waterproof motor. The geared motor 802 achieves self-locking after rotation through its built-in worm gear reduction structure. When the motor is powered on, the worm drives the turbine to rotate, which in turn drives the collection frame 9 to rotate through the drive shaft 803. When the motor is powered off and stops driving, due to the reverse self-locking characteristic of the worm gear transmission, the turbine cannot drive the worm to rotate in the reverse direction, causing the drive shaft 803 to be mechanically locked. The output end of the geared motor 802 is fixedly mounted with the drive shaft 803, and a connecting plate 805 is fixedly mounted on one end of the drive shaft 803. One end of the connecting plate 805 is fixed to one side of the collection frame 9. The lifting plate 7 is installed with a reinforcing support plate 801 fixedly mounted on one side. A bearing ring 804 is fixedly embedded on one side of the reinforcing support plate 801. The outer surface of the drive shaft 803 is fixedly connected to the inner ring of the bearing ring 804. Furthermore, the reinforcing support plate 801 provides stable support for the geared motor 802 and the drive shaft 803. In addition, the bearing ring 804 reduces the frictional resistance when the drive shaft 803 rotates, reducing mechanical wear. The geared motor 802 drives the connecting plate 805 to rotate through the drive shaft 803, which can drive the collection frame 9 to rotate. The rotation speed and angle of the collection frame 9 can be controlled to ensure that the fry enter the collection frame 9 smoothly with the water flow, avoiding fish collision damage caused by unstable rotation.

[0024] like Figures 1-5As shown, in a preferred embodiment, the outer surface of the support base 2 has two limiting sliding holes 16. Two limiting blocks 17 are fixedly connected to one side of the connecting block 6. The outer surfaces of the two limiting blocks 17 are slidably connected to the inner walls of the two limiting sliding holes 16. Two fixing blocks 14 are fixedly installed on the upper surface of the support base 2. The upper surfaces of the two fixing blocks 14 are fixedly installed to the bottom end of the variable frequency motor 3. A bearing ring 15 is fixedly embedded on the upper surface of the moving plate 1. The outer surface of the bottom end of the transmission screw 4 is fixedly connected to the inner ring of the bearing ring 15. A battery compartment 12 is fixedly installed on the upper surface of the moving plate 1. The battery compartment 12 is a waterproof, sealed ABS cuboid with a sealed door. It contains two sets of 12V / 20Ah batteries connected in parallel and a power management module. It is powered by a motor control switch connected to a waterproof wire. The electrical components of this device are all common electrical equipment in the prior art. This application will not elaborate further on their models or internal structures. Additionally, it is necessary to connect to the external control of the support base 2. The switch is connected, and a movable pusher 13 is fixedly installed on the upper surface of the battery compartment 12. Two sets of universal wheels 11 are fixedly installed on the bottom surface of the movable plate 1, and the universal wheels 11 have a self-locking braking structure. Furthermore, through the sliding cooperation of two limit blocks 17, the lifting trajectory of the lifting slider 5 can be limited to prevent the lifting slider 5 from rotating with the transmission screw 4, thus ensuring the verticality and stability of the lifting plate 7 during the lifting process. Two fixing blocks 14 are used to fix the variable frequency motor 3, which enhances the installation firmness of the variable frequency motor 3. The bearing ring 15 can provide bottom support for the transmission screw 4. With the drive of the top variable frequency motor 3, the rotation of the transmission screw 4 will be more stable. The battery compartment 12 can provide an independent power supply to ensure that the device can operate normally in the breeding environment without an external power supply. The movable pusher 13 and the universal wheels 11 cooperate to facilitate the flexible movement and fixation of the device, improve the convenience of transporting the device between different breeding ponds, and reduce the intensity of manual handling.

[0025] The working process of this utility model is as follows: When using the greenfin filefish juvenile transfer device in the later stage, the device is first quickly moved to the side of the target breeding pond by moving the pusher 13 and the universal wheel 11. Then the variable frequency motor 3 runs, which can drive the transmission screw 4 to rotate. The transmission screw 4 is connected to the threaded hole 18 at the lifting slider 5 by the thread, so the lifting slider 5 can slide up and down on the surface of the transmission screw 4. Then the lifting plate 7 is raised and lowered by the connecting block 6, thereby adjusting the water entry height of the collection frame 9 according to the depth of the breeding pond. Once the collection frame 9 is lowered to the appropriate water level, the geared motor 802 is started, which enables the drive shaft 803 to drive the connecting plate 805 and the collection frame 9 to rotate slowly. Then, the fry smoothly enter the collection frame 9 with the water flow and can be collected through the opening of the collection frame 9. After collection, the geared motor 802 drives the opening of the collection frame 9 to rotate upward, and at the same time, the variable frequency motor 3 lifts the lifting plate 7 to rise. Then, the device is moved to the target pond, and the geared motor 802 is started in reverse to tilt the collection frame 9, so that the fry can be smoothly poured into the new pond, improving the efficiency of pond pouring. This is the working process and working principle of the device.

[0026] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
