Description

Technical Field

[0001] This invention relates to the cultivation of greenfin filefish fry, and particularly to a greenfin filefish fry cultivation device and method. Background Technology

[0002] The cultivation of greenfin filefish fry mainly includes key steps such as broodstock cultivation, spawning and hatching, and fry cultivation. During the broodstock cultivation period, sandworms, oyster meat, and shrimp are fed twice a day, once in the morning and once in the afternoon. Feeding is stopped once the broodstock stop feeding. After feeding, the water needs to be changed manually to remove uneaten food and feces from the bottom of the pond. The cleaning process requires manually scooping up the fry, draining the water, and finally putting them back into clean water for cultivation. The process is very troublesome.

[0003] Therefore, the existing breeding of greenfin filefish fry needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a greenfin filefish fry rearing device that can automatically scoop up the fry and separate them from sewage, and automatically complete drainage and other actions.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] A greenfin filefish fry rearing device includes a rearing tank, a flip-transfer plate assembly is provided in the rearing tank, a movable baffle plate for sealing or opening the rearing tank is provided on the flip-transfer plate assembly, a drainage switch device is provided at the bottom of the rearing tank, a transmission component is provided between the drainage switch device and the flip-transfer plate assembly, a linkage component is provided between the rearing tank and the movable baffle plate, and a water filter hole is provided on the side wall of the flip-transfer plate assembly;

[0007] After the flipping transfer plate assembly flips 180°, the drainage switch device is opened by the transmission component, and the movable barrier plate is sealed by the linkage component.

[0008] After the flipping transfer plate assembly is reset and flipped, the drainage switch device is closed by the transmission component, and the movable barrier plate is controlled by the linkage component to open the cultivation tank and supply oxygen.

[0009] Furthermore, the flipping transfer plate assembly includes an arc-shaped bottom surface disposed within the cultivation tank, a rotating shaft hole is provided at the center of the arc-shaped bottom surface, a rotating shaft body is rotatably disposed within the rotating shaft hole, and a transfer plate is disposed at the inner end of the rotating shaft body.

[0010] Furthermore, the transfer disk is provided with a groove, which is an arc surface.

[0011] Furthermore, the movable barrier plate includes a strip-shaped opening disposed in the middle of the transfer disk, and a barrier plate hiding groove is provided on one side of the strip-shaped opening, and a barrier plate is movably disposed in the barrier plate hiding groove.

[0012] Furthermore, the drainage switch device includes a drainage groove disposed at the bottom of the cultivation tank, a valve stem blocking the drainage groove, and a drainage strip hole on the valve stem that can connect or block the drainage groove by changing its angle.

[0013] Furthermore, the transmission assembly includes a first pulley disposed at the rotating end of the transfer disc, a second pulley disposed at the rotating end of the valve stem, a transmission belt connecting the first pulley and the second pulley, and a drive motor connected to the end face of the second pulley.

[0014] Furthermore, the transmission ratio between the first pulley and the second pulley is 1:2;

[0015] When the second pulley rotates 180°, the first pulley rotates 90°.

[0016] Furthermore, the linkage component includes a drive rod disposed on the end face of the barrier plate, and a drive path groove is provided on the side wall of the cultivation pool, with the drive rod movably inserted into the drive path groove.

[0017] Furthermore, the drive path groove includes an arc-shaped groove, the center of which is concentric with the center of the first pulley, and one end of the arc-shaped groove is connected to a deviation guide groove that gradually deviates from the center of the first pulley.

[0018] When the drive rod moves to the position of the arc-shaped groove, it controls the barrier plate to seal the strip-shaped opening;

[0019] As the drive rod moves to the position deviating from the guide groove, the barrier plate is controlled to gradually open the strip opening.

[0020] The purpose of this invention is to provide a cultivation method:

[0021] Step 1: Place the parent fish into the rearing pond 1 and add water;

[0022] Step 2: Regularly feed the animals in the rearing tank 1 with food including sandworms, oyster meat, or shrimp.

[0023] Step 3: One hour after feeding, start the drive motor 504 to replace the water in the breeding pond 1 and remove the uneaten feed and feces from the water;

[0024] Step 4: During the flipping process of the flipping transfer plate assembly 2, the parent fish in the breeding tank 1 will be transferred to the flipping transfer plate assembly 2. At this time, the drainage switch device 4 at the bottom will automatically open and drain the water for replacement.

[0025] Step 5: Pour clean water into the cultivation tank 1 and reset the flip transfer plate assembly 2. At this time, the movable baffle plate 3 in the flip transfer plate assembly 2 will automatically open to provide more oxygen to the cultivation tank 1.

[0026] Step 6: Regularly check the gonadal development of the parent fish, and use them for breeding after the gonads have matured.

[0027] In summary, the advantages of this invention over the prior art are:

[0028] This invention addresses the shortcomings of existing methods for raising greenfin filefish fry. Through its structural design, this invention offers the following advantages: it enables comprehensive and automatic catching and separation of fry, automatic drainage of wastewater after separation, replacement with clean water, and rapid and automatic placement of fry after the addition of clean water, while automatically shutting off the drainage device. This allows for synchronized operation, improves work efficiency, reduces the input of manpower and resources, and is simple in structure and easy to use. Attached Figure Description
