Description

Technical Field

[0001] This invention relates to the field of turbot artificial breeding technology, and in particular to a separation device for turbot production. Background Technology

[0002] Since its successful development in the UK in the 1960s, turbot has become an important commercially farmed fish in Europe. After being introduced to China, thanks to the efforts of researchers, large-scale production-scale seedling technology was successfully developed in 1999. Subsequently, turbot farming quickly became widespread in the Shandong Peninsula, Hebei and Liaodong Peninsulas, and continued to extend southward to the coastal areas of Jiangsu, Zhejiang and Fujian, developing into one of the pillar industries of marine fish farming.

[0003] Turbot spawning technology refers to the process of promoting spawning in turbot under artificially controlled conditions. This technology effectively controls the turbot's reproductive process, improves reproductive efficiency, and ensures population stability and propagation. Traditional turbot spawning techniques typically employ natural spawning or artificial squeezing methods. For example, Chinese patent CN203608711U discloses a turbot spawning bed, which includes a cup holder and a turbot bed board. Its key feature is that the cup holder is machined to the lower left of the turbot bed board, and a fixing plate is machined to the upper right of the turbot bed board. Nuts are welded onto the fixing plate, and bolts are installed on top of the nuts. The advantages of this invention are that it is convenient to use and install, easy to clean and disinfect the fishpond, and has high work efficiency. While it facilitates turbot spawning to some extent, it still requires manual egg retrieval, and each time turbot needs to be manually placed, resulting in low egg retrieval efficiency. Furthermore, the uneven intensity of manual egg retrieval can easily damage the eggs. Therefore, we propose a separation device for turbot production. Summary of the Invention

[0004] The separation device for turbot production proposed in this invention solves the problems of low efficiency, uneven action intensity, and easy damage to eggs caused by manual egg retrieval in the background art.

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

[0006] A separation device for turbot production includes a cylindrical body. Inside the cylindrical body, a support column with an installation groove at the top is fixed in the middle. A rotary drive mechanism is installed inside the installation groove. The output shaft of the rotary drive mechanism is connected to a rotating disk rotatably connected to the top of the support column. Four turbot placement racks that can be quickly separated after being powered on are evenly arranged on the edge of the rotating disk. The four turbot placement racks correspond to the feeding point, washing point, egg collection point, and unloading point, respectively.

[0007] Above the rotating disc is a fixing ring that is fixed to the cylinder by a bracket. Spray pipes are installed on the fixing ring at the positions corresponding to the feeding and cleaning points. A limit plate is installed on the fixing ring at the position corresponding to the egg retrieval point. Two conductive blocks are installed on the fixing ring at the position corresponding to the unloading point.

[0008] Below the turbot placement rack at the egg collection site is an auxiliary egg collection mechanism that works in conjunction with the egg collection hole above it. The auxiliary egg collection mechanism is fixed on a support column.

[0009] In a preferred embodiment, a partition plate is installed inside the cylinder, which divides the inside of the cylinder into a liquid storage chamber and an egg storage chamber, with the egg storage chamber located below the egg retrieval site.

[0010] In a preferred embodiment, the auxiliary egg retrieval mechanism includes a housing fixed to a support column, an electric motor installed inside the housing, a horizontally arranged drive arm connected to the output shaft of the electric motor, a sliding column slidably connected to a motion frame installed on one side of the top of the drive arm, an L-shaped motion rod slidably inserted into the side wall of the housing fixed to one end of the motion frame, a swing arm hinged to the vertical section of the L-shaped motion rod extending to the outside of the housing, and a spring connecting the swing arm and the L-shaped motion rod, and two squeezing rollers rotatably connected to the other end of the swing arm.

[0011] In a preferred embodiment, the turbot placement rack includes a fixed frame installed at the edge of the rotating disk. A sliding rod is installed inside the fixed frame, and two sliders slidably connected inside the fixed frame are sleeved on the sliding rod. A spring is provided on the side of the two sliders that are far apart from each other and is sleeved on the sliding rod. A turbot placement plate that is slightly inclined downward is installed on one side of each slider. A side plate is installed on the side of the two turbot placement plates that are far apart from each other. An L-shaped positioning plate is installed at the lowest point of each turbot placement plate. A through-hole for egg retrieval is opened at the position where the lowest points of the two turbot placement plates are close to each other.

[0012] In a preferred embodiment, each of the turbot placement plates has an electromagnet embedded inside, and each of the top of the turbot placement plate has a conductive electrode post that is electrically connected to the electromagnet. When the conductive electrode post moves to the position of the conductive block and makes contact, the two electromagnets on the turbot placement rack are energized and generate repulsive magnetism.

[0013] In a preferred embodiment, the sliding rod has a V-shaped structure, and when the two sliders and the corresponding turbot placement plates move to both sides along the sliding rod and separate, the two turbot placement plates are also arranged in a V-shape.

[0014] In a preferred embodiment, the upper surface of the turbot placement plate is stepped, with the side plate, egg retrieval hole, and positioning plate all located at the lower end.

[0015] In a preferred embodiment, an inclined auxiliary feeding slide is installed on one side of the top of the cylinder via a bracket, and the highest point of the auxiliary feeding slide is located below the turbot placement rack at the feeding point.

[0016] In a preferred embodiment, the auxiliary egg retrieval mechanism is further provided with an egg guide channel located below the corresponding turbot placement plate on one side, and the egg guide channel is fixed on the side wall of the cylinder.

[0017] In a preferred embodiment, a support base plate is also installed on one side of the bottom of the cylinder. A battery, a liquid pump, and a pusher are installed on the top of the support base plate. A circulation conduit is connected between the spray pipe and the liquid storage chamber inside the cylinder. The liquid pump is connected to the circulation conduit. Casters are installed at the bottom of both the cylinder and the support base plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention proposes a separation device for turbot production. By setting up a turbot placement rack, a liquid pump, a liquid storage chamber and a liquid spray pipe, the outer surface of the turbot to be retrieved can be rinsed and disinfected before egg retrieval, preventing impurities on the outer surface of the turbot from entering the egg container during the subsequent egg retrieval process.

[0020] 2. With the addition of an auxiliary egg retrieval mechanism, a limiting plate, and a turbot placement rack, the turbot eggs can be retrieved through the movement of mechanical components. The operation is uniform, the egg retrieval efficiency is high, and damage to the eggs is reduced. The egg guide channel provides a buffer for the eggs as they fall and are collected.

[0021] 3. By setting up a conductive block, electromagnet, conductive electrode post and turbot placement rack, when the turbot moves to the unloading point, the turbot placement rack is separated by the repulsive magnetic force of the electromagnet after it is energized, and the turbot placed on it can be automatically unloaded under the action of gravity.

[0022] 4. The device is designed with a cylindrical body, a supporting base plate, casters, and a battery, making it easy to transport the device to the side of the turbot rearing pond for egg collection.

[0023] 5. Through the setting of the cylinder and partition plate, the interior of the cylinder can be divided into a liquid storage chamber and an egg storage chamber, so as to realize the storage of cleaning and disinfection solution and the temporary storage of turbot eggs;

[0024] This invention uses a rotary drive mechanism to adjust the position of the rotating disk and the turbot placement rack on it, thereby enabling the turbot in the placement rack to switch between the feeding, cleaning, egg collection and unloading positions. It integrates the feeding, cleaning, egg collection and unloading of turbot into one process, resulting in high turbot egg collection efficiency, low manual labor intensity, and uniform mechanical egg collection force with minimal egg damage.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1: Refer to Figure 1-9 A separation device for turbot production includes a cylinder 1. A support column 8 with an installation groove at the top is fixed in the middle of the cylinder 1. A rotary drive mechanism 7 is installed inside the installation groove. The rotary drive mechanism 7 can be a servo motor or other rotary mechanisms that rotate 90 degrees each time. The output shaft of the rotary drive mechanism 7 is connected to a rotating disk 5 that is rotatably connected to the top of the support column 8. An annular slide rail is installed between the rotating disk 5 and the support column 8. Four turbot placement racks 3 that can be quickly separated after being powered on are evenly arranged on the edge of the rotating disk 5. The four turbot placement racks 3 correspond to the feeding point, the washing point, the egg collection point, and the unloading point, respectively.

[0037] Above the rotating disk 5 is a fixing ring 4 fixed to the cylinder 1 by a bracket. A spray pipe 16 is installed on the fixing ring 4 at the position corresponding to the feeding point and the cleaning point. A limit plate 15 is installed on the fixing ring 4 at the position corresponding to the egg collection point. Two conductive blocks 17 are installed on the fixing ring 4 at the position corresponding to the unloading point. An inclined auxiliary unloading slide 18 is installed on one side of the top of the cylinder 1 by a bracket. The highest point of the auxiliary unloading slide 18 is located below the turbot placement rack 3 at the unloading point.

[0038] Below the turbot placement rack 3 located at the egg retrieval site, there is an auxiliary egg retrieval mechanism 2 that cooperates with the egg retrieval hole 302 on it. The auxiliary egg retrieval mechanism 2 is fixed on the support column 8.

[0039] The interior of the cylinder 1 is equipped with a partition plate 9, which divides the interior of the cylinder 1 into a liquid storage chamber and an egg storage chamber. The egg storage chamber is located below the egg retrieval point. On one side of the auxiliary egg retrieval mechanism 2, there is also an egg guide channel 14 located below the corresponding turbot placement plate 303. The egg guide channel 14 is fixed on the side wall of the cylinder 1. The egg guide channel 14 provides a buffer for the fall and collection of eggs, reducing damage to the eggs.

[0040] The auxiliary egg retrieval mechanism 2 includes a housing 201 fixed on a support column 8. An electric motor 203 is installed inside the housing 201. The output shaft of the electric motor 203 is connected to a horizontally arranged drive arm 202. A sliding column 205 is slidably connected to a motion frame 206 on one side of the top of the drive arm 202. An L-shaped motion rod 204 is fixed to one end of the motion frame 206 and slidably inserted into the side wall of the housing 201. A swing arm 208 is hinged to the vertical section of the L-shaped motion rod 204 extending to the outside of the housing 201. A spring 207 is connected between the swing arm 208 and the L-shaped motion rod 204. Two squeezing rollers 209 are rotatably connected to the other end of the swing arm 208. Rubber protrusions are provided on the outside of the squeezing rollers 209. The squeezing rollers 209 reciprocate back and forth, and squeeze the eggs after contacting the belly of the turbot.

[0041] The turbot placement rack 3 includes a fixed frame 308 installed at the edge of the rotating disk 5. A sliding rod 310 is installed inside the fixed frame 308. Two sliders 307 are slidably connected inside the fixed frame 308 and sleeved on the sliding rod 310. On the side of the two sliders 307 that are far apart from each other, there is a spring 306 sleeved on the sliding rod 310. A turbot placement plate 303 that is slightly inclined downward is installed on one side of each slider 307. A side plate 304 is installed on the side of the two turbot placement plates 303 that are far apart from each other. An L-shaped positioning plate 301 is installed at the lowest end of each turbot placement plate 303. A through egg retrieval hole 302 is opened at the position where the lowest ends of the two turbot placement plates 303 are close to each other.

[0042] The upper surface of the turbot placement plate 303 is stepped, with the side plate 304, egg collection hole 302 and positioning plate 301 all located at the lower end. When the turbot is placed, it is placed at the bottom of the turbot placement plate 303, surrounded by the side plate 304 and positioning plate 301, with its belly located at the egg collection hole 302.

[0043] A support base plate 6 is installed on one side of the bottom of the cylinder 1. A battery 12, a liquid pump 11, and a pusher 10 are installed on the top of the support base plate 6. A circulation conduit is connected between the spray pipe 16 and the liquid storage chamber inside the cylinder 1. The liquid pump 11 is connected to the circulation conduit. Both the bottom of the cylinder 1 and the support base plate 6 are equipped with casters 13. The liquid pump 11 and the circulation conduit can continuously spray the cleaning and disinfecting liquid in the liquid storage chamber through the spray pipe 16 to disinfect the turbot before egg retrieval. The support base plate 6, the pusher 10, and the casters 13 make it easy to move the device to the side of the turbot rearing pond.

[0044] In use, the operator pushes the universal wheels 13 at the bottom of the device via the push frame 10, moving the device to the vicinity of the turbot rearing pond. Then, cleaning and disinfecting solution is added to the storage chamber, and the liquid pump 11 and servo motor are started. The operator places the turbot spawning fish one by one onto the turbot placement rack 3, with their bellies positioned at the egg collection hole 302. Under the action of the liquid pump 11, the cleaning and disinfecting solution is sprayed out through the spray pipe 16, thus cleaning the turbot on the turbot placement rack 3 at the feeding and cleaning stations. After cleaning, the cleaning and disinfecting solution continues to flow into the storage chamber for recycling. The output shaft of the servo motor drives the rotating disk 5 to rotate, thereby moving the turbot placement rack 3 and... The turbot is adjusted to a working position. When it moves to the spawning area, the auxiliary egg-collecting mechanism 2 is activated. The output shaft of the motor 203 drives the drive arm 202 to rotate. The drive arm 202 drives the sliding column 205 to slide within the moving frame 206, thereby driving the moving frame 206 and the L-shaped moving rod 204 to move back and forth. This causes the extrusion roller 209 to continuously roll and extrude on the turbot's belly, squeezing the eggs out of the turbot's belly, thus collecting the turbot eggs. The collected eggs flow into the egg storage cavity through the egg guide channel 14 for temporary collection. Then, the turbot placement rack 3 and the turbot on it move to the unloading area under the action of the servo motor, and the turbot with the collected eggs is taken out.

[0045] Example 2: Figure 8 , 9 As shown, unlike Embodiment 1, in order to further realize the automatic unloading of turbot eggs, electromagnets 305 are embedded inside the turbot placement plate 303, and the top of the turbot placement plate 303 is fixed with a conductive electrode post 309 electrically connected to the electromagnet 305. When the conductive electrode post 309 moves to the position of the conductive block 17 and contacts it, the two electromagnets 305 on the turbot placement frame 3 are energized and generate repulsive magnetism. The sliding rod 310 has a V-shaped structure. When the two sliders 307 and the corresponding turbot placement plate 303 move to both sides along the sliding rod 310 and separate, the two turbot placement plates 303 are finally set in a V-shape after moving with the sliders 307. The V-shaped design further facilitates the turbot to fall under its own gravity after the two turbot placement plates 303 are separated.

[0046] When the turbot placement rack 3 moves to the feeding point, the conductive electrode post 309 at the top of the turbot placement plate 303 contacts the corresponding conductive block 17, the circuit of the electromagnet 305 is energized and generates magnetism, the magnetism generated by the two electromagnets 305 repulses each other, thereby driving the two turbot placement plates 303 to move away from each other, the slider 307 slides on the compression spring 306 of the V-shaped sliding rod 310, and after the two turbot placement plates 303 move, they are set in a V-shape. The turbot falls onto the auxiliary feeding slide 18 under the action of gravity, and slides into the feeding tank on one side with the auxiliary feeding slide 18.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
