Description

Technical Field

[0001] This invention relates to the field of Litopenaeus vannamei (South American shrimp) farming technology, specifically to a highly active Litopenaeus vannamei farming pond that can automatically adjust the farming density. Background Technology

[0002] Adjusting the stocking density in existing Litopenaeus vannamei ponds usually requires manual intervention and management, including adjusting the stocking quantity, controlling the amount of feed, and adjusting the area of ​​the stocking area. The selection of stocking density should be based on a comprehensive consideration of specific stocking conditions, water quality, shrimp species, and feeding management. In addition, the stocking density adjustment in existing Litopenaeus vannamei ponds is usually done manually.

[0003] However, the current practice of artificial feeding may lead to feed waste, as some feed may settle at the bottom or float on the surface, failing to be fully utilized by shrimp. This not only wastes feed resources but may also cause water quality problems and environmental pollution. Furthermore, during artificial feeding, it is difficult to ensure that the feed is evenly distributed in the pond, and some shrimp may not be able to find enough feed in time, leading to uneven growth. Artificial feeding requires reasonable control and management of the feeding amount and frequency, which requires farmers to have certain experience and skills, as well as invest a lot of time and energy in feeding management.

[0004] Furthermore, because feed used in South American shrimp farming ponds sometimes remains on the water surface, forming floating debris, if this feed residue is not fully digested and absorbed by the shrimp, it will float on the water. Shrimp also produce feces and metabolic products during the farming process. These substances gradually decompose in the water, and some of them will float to the surface, making the pond turbid and affecting the dissolved oxygen content in the water. This will cause the shrimp to have difficulty breathing, increasing their risk of disease. These floating objects will also reduce the shrimp's swimming space, restricting their activity and reducing their ability to move and grow normally.

[0005] Therefore, a highly active South American shrimp culture pond with automatically adjustable stocking density was proposed to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to propose a highly active South American shrimp farming pond that can automatically adjust the stocking density, so as to solve the problems in the prior art where it is difficult to manually control the timing of shrimp feed delivery and the deterioration of water quality caused by floating debris in shrimp ponds, which also harms shrimp growth.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a highly active Litopenaeus vannamei (South American shrimp) culture pond with automatically adjustable stocking density, comprising a water storage tank, a fixed frame fixedly connected above the water storage tank, a motor installed on the fixed frame, and a water supply pipe fixedly connected to the upper surface of the water storage tank, characterized in that the highly active Litopenaeus vannamei (South American shrimp) culture pond with automatically adjustable stocking density includes an automatic sewage discharge mechanism, an automatic water supply mechanism, and an automatic feeding mechanism, wherein the automatic sewage discharge mechanism is located in the middle of the water storage tank, the automatic water supply mechanism is located on the upper surface of the water storage tank, and the automatic feeding mechanism is located on the fixed frame;

The one-way conveying pipe is fixedly connected to the upper surface of the water storage tank. The automatic water supply mechanism is used to replenish the water flow when the water in the water storage tank is being discharged.

[0011] Preferably, the automatic sewage discharge mechanism further includes a drive shaft with a sleeve on the outside of the drive shaft. The sleeve is fixedly connected to the water storage tank, and the drive shaft is rotatably connected in the sleeve. An L-shaped bracket is fixedly connected to the outer surface of the sleeve.

The extrusion column on the turntable is slidably connected in the groove of the T-shaped block.

[0013] Preferably, the bottom of the cylinder is slidably connected to the drain pipe, and the cylinder is connected to the drain pipe. A flexible hose is provided at the connection between the cylinder and the drain pipe for the cylinder to reciprocate to collect dirt from the water surface.

[0014] Preferably, the automatic water supply mechanism also includes a belt, one end of which is driven to a drive shaft, and the other end of which is driven to a ball valve. The ball valve is rotatably connected inside the water supply pipe for controlling the water flow.

[0015] Preferably, the ball valve has an L-shaped hole in the middle, and the L-shaped hole is connected to the water supply pipe and the one-way delivery pipe. The one-way delivery pipe is installed on the water supply pipe and is connected to the water supply pipe.

[0016] Preferably, the automatic feeding mechanism further includes a transmission belt, one end of which is connected to a motor drive shaft, and the other end of which is connected to an auxiliary transmission wheel.

[0018] Compared with the prior art, the present invention provides a highly active Litopenaeus vannamei (South American shrimp) culture pond that can automatically adjust the culture density, and has the following beneficial effects:

[0019] 1. By setting up an automatic feeding mechanism, we can ensure that shrimp receive feed evenly in the pond, thus avoiding food and nutrient deficiencies in some shrimp due to insufficient intake. This guarantees the growth and development of the entire shrimp population, maximizes feed utilization, and fully meets the needs of shrimp with each feeding, reducing overfeeding and feed waste, and saving farming costs. Automatic quantitative and timed feeding ensures that each shrimp receives enough food within a specified time, reducing competition and food contention among shrimp, which helps reduce stress and disease occurrence, and improves farming efficiency. At the same time, by reducing the accumulation of uneaten feed and the decomposition of organic waste, we can reduce the risk of water quality deterioration and improve water cleanliness and ecological balance.

[0020] 2. The automatic water supply system can promptly remove waste and pollutants from the aquaculture pond, maintaining clean and stable water quality. This helps provide a good growth environment, reducing the occurrence and mortality of diseases. By setting an appropriate water level, suitable water depth and flow rate can be provided, improving the growth efficiency and aquaculture yield of shrimp. At the same time, the automatic water supply system can also increase the dissolved oxygen content in the aquaculture pond by stirring the water with water flow. No manual operation is required, saving labor and time costs in the aquaculture process. Furthermore, the stable aquaculture environment helps reduce stress on shrimp and improve their growth and resistance.

[0021] 3. The automatic sewage discharge mechanism and automatic cleaning system can effectively remove debris and duckweed, avoiding water quality deterioration and affecting water cleanliness if common pollution sources such as debris and duckweed are not removed in time. The automatic feeding mechanism can automatically remove debris and duckweed to reduce harm to shrimp growth, reduce the accumulation of debris and duckweed on the water surface, and thus prevent blockage of aquaculture equipment and channels, increase water circulation, simplify aquaculture operations, and prevent these debris from becoming a breeding ground for parasites and other harmful organisms. Timely removal of these debris can reduce blockages and the occurrence of parasites. Attached Figure Description

[0050] For further embodiments, please refer to Figures 7 to 9 As shown:

[0051] The automatic feeding mechanism 4 includes a hopper 404 for storing feed. The two sides of the hopper 404 are fixedly connected to the fixed frame 101. The automatic feeding mechanism 4 is used to spread feed in the water storage tank 1.

The upper end of the power shaft 402 is fixedly connected to the extrusion plate 403. The end of the extrusion plate 403 away from the power shaft 402 is rotatably connected to the hopper 404. The hopper 404 has uniformly opened discharge holes. A discharge cylinder 406 is fixedly connected to the discharge holes of the hopper 404. A sealing strip 407 is installed at the bottom of the discharge cylinder 406. The middle part of the sealing strip 407 is rotatably connected to the discharge cylinder 406.

[0054] Through the implementation of this embodiment, the automatic removal system can effectively remove debris and duckweed, avoiding the problem of water quality deterioration and affecting water cleanliness caused by the failure to remove common pollution sources such as debris and duckweed in time, and reducing the harm to shrimp growth.

[0055] The working principle of all the content in the above embodiments is as follows:

[0056] In the initial state: the water level in the reservoir 1 is the same as the height of the cylinder 206.

[0057] The following describes the working process of the automatic sewage discharge mechanism 2 and the automatic water supply mechanism 3 in removing impurities from the water surface:

[0058] Impurities on the water surface are removed by the reciprocating motion of the automatic sewage discharge mechanism 2.

[0059] In use, under the control of the power system, the drive shaft on the transmission shaft 201 is started to rotate clockwise, causing the transmission shaft 201 to rotate in the middle of the sleeve 202. Simultaneously, this causes the turntable 204 at the other end of the transmission shaft 201 to begin rotating clockwise. Because a pressing block is installed at the end of the turntable 204 away from the transmission shaft 201, and the pressing block slides within a groove on the T-shaped block 205, the clockwise rotation of the turntable 204 causes the T-shaped block 205 to reciprocate up and down around the turntable 204. Simultaneously, because the end of the T-shaped block 205 away from the turntable 204 is fixed to the bottom of the cylinder 206, and due to the interaction between the cylinder 206 and the drain pipe 208, the reciprocating motion of the T-shaped block 205 causes the cylinder 206 to reciprocate up and down within the drain pipe 208. Meanwhile, because the water storage tank 1... The cylinder 206 contains water at the same height as the cylinder. When the cylinder 206 moves downward, the water flows along the cylinder 206 and is discharged into the sewage tank through the sewage pipe 208. When the water flows into the cylinder 206, the water flow will cause the debris on the surface of the tank to flow into the cylinder 206 as well. Because the cylinder 206 is equipped with a filter screen 207, insoluble debris and floating dust can be stored in the filter screen 207, which is conducive to subsequent collection and treatment. When the cylinder 206 moves upward again and exceeds the water surface, the water cannot flow out through the cylinder 206 because the cylinder 206 is higher than the liquid surface. By automatically removing debris and duckweed, the harm to the growth of Litopenaeus vannamei can be reduced, the accumulation of debris and duckweed on the water surface can be reduced, thereby preventing blockage of aquaculture equipment and channels, increasing water circulation and simplifying aquaculture operations.

[0060] Water supply after impurities and sewage are removed from the water surface by the automatic water supply mechanism 3:

[0061] In use, the drive shaft 201 rotates clockwise, causing the ball valve 303 above the drive shaft 201 to rotate clockwise via the belt 301. Simultaneously, because the ball valve 303 has a water flow hole in its center, water flows from the water supply pipe 103 into the one-way delivery pipe 302. When the ball valve 303 rotates clockwise with the support of the one-way delivery pipe 302, the water in the water supply pipe 103 continuously flows towards the one-way delivery pipe 302 as the ball valve 303 rotates. Furthermore, the water supply pipe 103... Under the action of valve 303, the water flowing into the one-way conveying pipe 302 is equal to the water flow reciprocating in the automatic sewage discharge mechanism 2 under manual setting, thereby realizing the water flow circulating in the water storage tank 1. The water circulation can increase the oxygen in the water and increase the dissolved oxygen content in the breeding tank. No manual operation is required, saving labor and time costs in the breeding process. A stable breeding environment helps to provide good growth conditions for South American shrimp, improve the shrimp's resistance, and provide sufficient oxygen, which is very important for the growth and health of South American shrimp.

[0062] Please refer to the above work process. Figures 1 to 6 .

[0063] The following is the working process of the automatic feeding mechanism 4 for automatic feeding and timed spreading:

[0064] In operation, after the automatic sewage discharge mechanism 2 and the automatic water supply mechanism 3 have processed the debris on the surface of the water in the storage tank 1, the drive shaft in the drive motor 102 begins to rotate clockwise. Under the transmission action of the transmission belt 401, the power shaft 402 at the other end of the motor 102 will also begin to rotate clockwise. Because an extrusion disc 403 is fixed above the power shaft 402, and the axis of the extrusion disc 403 rotates on the hopper 404 and is fixedly connected to the pusher fan 405, the clockwise rotation of the power shaft 402 will drive the extrusion disc 403 and the pusher fan 405 to rotate clockwise. The pusher fan 405 rotates clockwise in the coaxial direction. Because the hopper 404 has evenly spaced discharge holes, and each discharge hole is equipped with a discharge cylinder 406, when feed for spreading is in the hopper 404, the rotation of the pusher fan 405 pushes the feed along the discharge holes into the discharge cylinder 406. A sealing strip 407 is installed at the bottom of the discharge cylinder 406, and the middle of the sealing strip 407 is rotatably connected to the discharge cylinder 406. The end of the sealing strip 407 away from the discharge cylinder 406 slides on the extrusion disc 403. A semi-circular groove is provided on the extrusion disc 403. When the extrusion disc 403 rotates clockwise, one end of the sealing strip 407 slides on the bottom of the extrusion disc 403. Due to the squeezing action at the bottom of the extrusion disc 403, the sealing strip 407 will close at the bottom of the feed cylinder 406. When the end of the sealing strip 407 away from the feed cylinder 406 slides onto the semi-circular groove on the extrusion disc 403, the sealing strip 407 is no longer squeezed by the bottom of the extrusion disc 403, and the end of the sealing strip 407 near the feed cylinder 406 will slide along the sealing strip under the action of gravity. When the middle part of strip 407 rotates counterclockwise downwards, the sealing strip 407 will open at the bottom of the feeding cylinder 406, further spreading the feed in the feeding cylinder 406 into the water storage tank 1. Because the extrusion disc 403 rotates continuously, the sealing strip 407 will open continuously, thus spreading the feed in the feeding cylinder 406 into the water storage tank 1 for shrimp farming. Quantitative and timed feeding can ensure that shrimp in the farming pond receive feed evenly, avoiding insufficient food and nutrition for some shrimp, and ensuring the growth and development of the entire farming population.

[0065] Please refer to the above work process. Figures 7 to 9 .

[0066] Overview:

[0067] With the automatic sewage discharge mechanism 2, automatic quantitative and timed feed delivery ensures that shrimp receive feed evenly in the pond, thus preventing some shrimp from suffering from food and nutrient deficiencies due to insufficient intake. This guarantees the growth and development of the entire shrimp population, maximizes feed utilization, and ensures that each feeding fully meets the shrimp's needs, reducing overfeeding and feed waste, and saving on farming costs. The automatic feeding mechanism 4 automatically removes debris and duckweed to reduce harm to shrimp growth, minimizes the accumulation of debris and duckweed on the water surface, prevents blockage of farming equipment and channels, increases water circulation, and simplifies farming operations.
