Description

Technical Field

[0001] This invention belongs to the field of snail farming, and specifically relates to a high-density, factory-style snail farming equipment. Background Technology

[0002] With the development of the economy, society, and aquaculture technology, traditional pond farming methods are revealing more and more problems, leading to the rise of high-density factory farming. "Small snails, big industry"—in recent years, with the development of ready-to-eat food industries such as snail rice noodles and snail and duck feet stew, the market demand for snails has surged. Traditional snail farming methods generally employ polyculture models in ponds, paddy fields, lakes, reservoirs, and ditches, making it difficult to recover and control the yield and quality of farmed snails. There is an urgent need for high-density factory farming equipment and supporting technologies for snails to meet the market's demand for both quality and quantity. Snails belong to the class Gastropoda, subclass Probranchia, family Viviparidae. In their natural state, they are mostly distributed on the surface of mud, sand, or rocks in freshwater areas. They are omnivorous, with their main feeding organ being the radula, used to scrape algae and organic debris from the walls and filter-feed plankton. They are nocturnal and prefer to feed at night. Duckweed, with its high protein and rich nutrients, has become one of the snails' favorite foods and can be introduced into snail farming water as a primary food source.

[0003] Since most snails crawl along the walls of water bodies, traditional breeding sites or equipment lack components or methods to increase their activity space, resulting in insufficient utilization of breeding space and a limited number of snails that can be raised. Furthermore, there is currently no affordable and high-quality snail feed available on the market, and existing breeding sites or equipment lack components or methods for collecting solid waste from the breeding water and providing suitable water flow, which is inconvenient for snail breeding and management. This easily leads to low snail yields and poor quality. Summary of the Invention

[0004] The main objective of this invention is to propose a high-density, factory-style snail farming equipment, which aims to solve the technical problems of existing farming sites or equipment lacking components or methods for collecting solid waste and ensuring water flow, as well as components or methods for increasing the snails' activity space.

[0005] To achieve the above objectives, the present invention proposes a high-density factory farming equipment for snails, comprising a rootless duckweed farming pond and a snail farming pond. The snail farming pond for raising snails is located on the outer side of the rootless duckweed farming pond, and the height of the rootless duckweed farming pond is higher than the height of the snail farming pond. The equipment also includes a water circulation mechanism, a partition mechanism, and a solid waste collection mechanism. The water circulation mechanism is disposed on the rootless duckweed farming pond and the snail farming pond, the partition mechanism is disposed on the top of the snail farming pond, and the solid waste collection mechanism is disposed on the bottom of the snail farming pond.

[0006] The water circulation mechanism includes a water pump, a nutrient transfer pipe, a pumping pipe, a pumping transmission pipe, a drainage transmission pipe, and a drainage branch pipe. Multiple pumping pipes equipped with pumping valves are located on the side of the snail breeding pond away from the rootless duckweed breeding pond. These multiple pumping pipes are interconnected via pipes and are also connected to the snail breeding ponds. One end of each pumping transmission pipe is connected to the interconnecting pipes among the multiple pumping pipes. The pump's inlet is connected to the other end of the pumping transmission pipe. A drainage outlet is located near the water discharge outlet. The water inlet of the drainage transmission pipe of the water valve is connected to the outlet of the water pump. The water inlet of the drainage branch pipe equipped with the drainage branch valve is connected to the outer wall of the drainage transmission pipe. The water outlet of the drainage branch pipe is connected to the top of the rootless duckweed culture pond. The middle position of the nutrient transmission pipe equipped with the nutrient pipe valve is connected to the water outlet of the drainage transmission pipe. One end of the top of the inclined nutrient transmission pipe is connected to the rootless duckweed culture pond, and one end of the bottom is connected to the snail culture pond.

[0007] The spacing mechanism includes support blocks, support crossbars, and folding plate components. Multiple support blocks for limiting positioning are arranged on the front and rear sides of the top end face of the snail breeding pond. The front and rear sides of the support crossbars are supported on the support blocks. Each folding plate component for increasing the snails' activity space is respectively fitted into the middle part of each support crossbar.

[0008] The solid waste collection mechanism includes a bottom slag hopper, a gate, and a transparent collection tank. The bottom slag hopper is located in the middle of the bottom of the snail breeding pond. The gate is horizontally embedded in the bottom of the bottom slag hopper and can slide inside the bottom slag hopper. The transparent collection tank, with graduations on its outer wall, is installed on the bottom end face of the bottom slag hopper.

[0009] Preferably, the water outlet of the drainage transmission pipe is connected to the nutrient transmission pipe near the top of the pipe, and the drainage valve is installed between the connection between the drainage transmission pipe and the drainage branch pipe and the water outlet of the drainage transmission pipe.

[0010] Preferably, a plate connecting cylinder is provided at the middle position of the folding plate component, the supporting crossbar passes through the middle position of the plate connecting cylinder, rubber plates are provided on the left and right end faces of the plate connecting cylinder, a first plate is connected to one side of the plate connecting cylinder through the rubber plate, and a second plate is connected to the other side of the plate connecting cylinder through the rubber plate. The first plate and the second plate can move on the left and right sides of the plate connecting cylinder respectively through the rubber plate.

[0011] Preferably, a first arc-shaped hole is provided in the middle part of the rear side of the first plate, and a second arc-shaped hole is provided in the middle part of the front side of the second plate.

[0012] Preferably, a snail mesh is provided at the top of the interior of the bottom slag collection hopper, and multiple bottom lighting components are installed on the snail mesh.

[0013] Preferably, the bottom of the bottom lighting component is provided with a triangular prism support frame, on which multiple lighting lamps are installed, and each lighting lamp is respectively equipped with a transparent conical cover.

[0014] Preferably, the inner wall of the snail breeding pond near the water pumping pipe is provided with a side wall connecting groove, the side wall connecting groove is connected to the water inlet of the water pumping pipe, and a nutrient separator for separating rootless duckweed is embedded in the side wall connecting groove.

[0015] Compared with existing technologies, the present invention has the following advantages:

[0016] 1. The water circulation mechanism in this invention allows oxygen-rich fresh water to flow within the snail breeding pond after injection, thereby controlling the amount of duckweed added from the duckweed breeding pond to the snail breeding pond. This reduces or eliminates the harm caused by the duckweed consuming oxygen and producing carbon dioxide during nighttime respiration in the snail breeding pond, which leads to oxygen deficiency and death of the farmed snails. This effectively improves the practicality of the equipment.

[0017] 2. The spacing mechanism in this invention can adjust the flow direction of water in the snail breeding pond and increase the activity space of the snails in the pond, thereby allowing more snails to be raised in the pond and making full use of the space, effectively increasing the yield of snail farming.

[0018] 3. The solid waste collection mechanism in this invention can prevent snails from falling into the bottom slag hopper, and can also collect snail excrement and uneaten food, thus facilitating the treatment of snail excrement and uneaten food collected in the transparent collection tank, ensuring the stability of water quality in the snail breeding pond. It can also illuminate the snail breeding pond with multiple lights, facilitating the photosynthesis of the rootless duckweed and the observation of the snail breeding pond conditions, effectively demonstrating the convenience of equipment use.

[0031] like Figures 1-6 As shown, this embodiment discloses a high-density factory farming equipment for snails, including a rootless duckweed farming pond 1 and a snail farming pond 2. The snail farming pond 2, used for raising snails, is located on the outer side of the rootless duckweed farming pond 1. The height of the rootless duckweed farming pond 1 is higher than the height of the snail farming pond 2. It also includes a water circulation mechanism, a partition mechanism, and a solid waste collection mechanism. The water circulation mechanism is set on the rootless duckweed farming pond 1 and the snail farming pond 2, the partition mechanism is set on the top of the snail farming pond 2, and the solid waste collection mechanism is set on the bottom of the snail farming pond 2.

[0032] The water circulation mechanism includes a water pump 6, a nutrient transfer pipe 7, a pumping pipe 9, a pumping transfer pipe 11, a drainage transfer pipe 12, and a drainage branch pipe 13. Multiple pumping pipes 9, each equipped with a pumping valve 10, are located on the side of the snail breeding pond 2 away from the rootless duckweed breeding pond 1. These multiple pumping pipes 9 are interconnected via pipes and are also connected to the snail breeding pond 2. One end of the pumping transfer pipe 11 is connected to the interconnecting pipes among the multiple pumping pipes 9. The pumping port of the water pump 6 is connected to the other end of the pumping transfer pipe 11. A [missing information - likely a valve or valve] is installed near the water outlet. The water inlet of the drainage transmission pipe 12 of the drainage valve 15 is connected to the outlet of the water pump 6. The water inlet of the drainage branch pipe 13, which is equipped with the drainage branch valve 14, is connected to the outer wall of the drainage transmission pipe 12. The water outlet of the drainage branch pipe 13 is connected to the top of the rootless duckweed breeding pond 1. The middle position of the nutrient transmission pipe 7, which is equipped with the nutrient pipe valve 8, is connected to the water outlet of the drainage transmission pipe 12. The top end of the inclined nutrient transmission pipe 7 is connected to the rootless duckweed breeding pond 1, and the bottom end is connected to the snail breeding pond 2.

[0033] The spacing mechanism includes support blocks 16, support crossbars 30, and folding plate components. Multiple support blocks 16 for limiting the position are set on the front and rear sides of the top end face of the snail breeding pond 2. The front and rear sides of the support crossbars 30 are mounted on the support blocks 16. Each folding plate component for increasing the snail's activity space is respectively fitted in the middle part of each support crossbar 30.

[0034] The solid waste collection mechanism includes a bottom slag hopper 3, a gate 4, and a transparent collection tank 5. The bottom slag hopper 3 is located in the middle of the bottom of the snail breeding pond 2. The gate 4 is horizontally embedded in the bottom of the bottom slag hopper 3 and can slide inside the bottom slag hopper 3. The transparent collection tank 5, with graduations on its outer wall, is installed on the bottom end face of the bottom slag hopper 3.

[0035] In a preferred embodiment, the water outlet of the drainage transmission pipe 12 is connected to the nutrient transmission pipe 7 near the top of the pipe. The drainage valve 15 is installed between the connection between the drainage transmission pipe 12 and the drainage branch pipe 13 and the water outlet of the drainage transmission pipe 12. Rootless duckweed floating on the surface in the rootless duckweed culture pond 1 can be transferred from the connected nutrient transmission pipe 7 to the snail culture pond 2. The water circulation mechanism allows oxygen-rich fresh water to flow within the snail culture pond 2 after injection, thereby controlling the amount of rootless duckweed released from the rootless duckweed culture pond 1 into the snail culture pond 2. Rootless duckweed thrives in the absence of light or at night. Since the snails undergo plant respiration and absorb oxygen to produce carbon dioxide, it is necessary to stop adding or placing rootless duckweed into the snail breeding pond 2 at night or in the absence of light. During the day, when there is light and the rootless duckweed can photosynthesize, open the nutrient pipe valve 8 installed on the nutrient transfer pipe 7, and place the appropriate number and type of snails into the water-filled snail breeding pond 2 as needed. Then, the water pump 6 installed below the snail breeding pond 2 will provide suction force, causing the water pumping pipe 9 to draw water from the snail breeding pond 2. The water pumping pipe 9 can be opened or closed according to the water level in the snail breeding pond 2. Valve 10, located above the liquid level in the snail breeding pond 2, allows the corresponding installed pumping valve 10 to be closed. When the pumping pipe 9 is at or below the liquid level, the corresponding installed pumping valve 10 remains open, allowing water to flow from the pumping pipe 9 to the pumping transmission pipe 11, and then from the pumping transmission pipe 11 to the drainage transmission pipe 12. During the day, when there is sunlight and no duckweed can photosynthesize, the drainage branch valve 14 installed on the drainage branch pipe 13 can be opened. Simultaneously, the drainage valve 15 installed on the drainage transmission pipe 12 can be closed or opened, allowing water in the drainage transmission pipe 12 to flow through the drainage branch pipe 13. The water is fed into the rootless duckweed culture pond 1, allowing the rootless duckweed and water on the surface of the rootless duckweed culture pond 1 to flow into the snail culture pond 2 through the nutrient transfer pipe 7. At the same time, when the drain valve 15 is closed, the water in the drain transfer pipe 12 will only be transferred to the rootless duckweed culture pond 1 through the drain branch pipe 13. When the drain valve 15 is opened, the water in the drain transfer pipe 12 is transferred to the rootless duckweed culture pond 1 through the drain branch pipe 13, and at the same time, the water in the drain transfer pipe 12 can also be directly transferred to the nutrient transfer pipe 7 and then transferred to the snail culture pond 2 through the nutrient transfer pipe 7, so that the water in the snail culture pond 2 flows or is transferred from right to left.

[0036] At night or in the absence of light, the nutrient pipe valve 8 installed on the nutrient transfer pipe 7 and the drainage branch valve 14 installed on the drainage branch pipe 13 need to be closed in advance, while the drainage valve 15 installed on the drainage transfer pipe 12 needs to be opened. The suction force provided by the water pump 6 allows the water pumping pipe 9 to draw water from the snail breeding pond 2 into the pumping transfer pipe 11, then from the pumping transfer pipe 11 to the drainage transfer pipe 12, and finally from the drainage transfer pipe 12 to the nutrient transfer pipe 7. Because the nutrient pipe valve 8 installed on the nutrient transfer pipe 7 is located near the top, and the water transported by the drainage transfer pipe 12 is directly delivered to the nutrient transfer pipe 7... The water then flows downwards or is transferred to snail breeding pond 2 from the middle section of the pond. This allows the equipment to maintain water circulation in snail breeding pond 2 even when the feeding of rootless duckweed is stopped, thereby increasing the oxygen content in the water of snail breeding pond 2. This stops the feeding of rootless duckweed from rootless duckweed breeding pond 1 into snail breeding pond 2. Once the rootless duckweed in snail breeding pond 2 is consumed by the snails or the number of them is reduced, the oxygen consumption and carbon dioxide production caused by the respiration of rootless duckweed in snail breeding pond 2 at night are reduced or eliminated, thus reducing the risk of oxygen deficiency and death of the farmed snails. This effectively improves the practicality of the equipment.

[0037] In a preferred embodiment, a plate connecting cylinder 24 is provided at the middle position of the folding plate component, and a supporting crossbar 30 passes through the middle position of the plate connecting cylinder 24. Rubber plates 25 are provided on the left and right end faces of the plate connecting cylinder 24. A first plate surface 26 is connected to one side of the plate connecting cylinder 24 through the rubber plate 25, and a second plate surface 28 is connected to the other side through the rubber plate 25. The first plate surface 26 and the second plate surface 28 can move on the left and right sides of the plate connecting cylinder 24 respectively through the rubber plate 25. The folding plate component can be folded by the rubber plate 25 made of soft rubber material. The bottom end faces of the first plate surface 26 and the second plate surface 28 are spaced from the snail mesh 19 installed in the snail breeding pond 2 to ensure the speed of water flow. The folding plate components are mounted on the support block 16 via the support crossbar 30 and inserted into the snail breeding pond 2. The front and rear ends of the first plate surface 26 and the second plate surface 28 are in contact with the inner wall of the snail breeding pond 2, allowing snails that cannot swim in the water to climb up the inner wall of the snail breeding pond 2 to the first plate surface 26 and the second plate surface 28 of the multiple folding plate components to eat the attached rootless duckweed. The multiple folding plate components installed in the snail breeding pond 2 allow the rootless duckweed to attach and stay, allowing the snails to climb up to the first plate surface 26 and the second plate surface 28 of the folding plate components to eat the rootless duckweed. It also provides the snails with a lot of room to move around in the snail breeding pond 2, allowing more snails to be raised in the snail breeding pond 2 and reducing the waste of space in the snail breeding pond 2.

[0038] In a preferred embodiment, a first arc-shaped hole 27 is provided in the middle of the rear side of the first plate 26, and a second arc-shaped hole 29 is provided in the middle of the front side of the second plate 28. The water level in the snail breeding pond 2 is not higher than the first arc-shaped hole 27 and the second arc-shaped hole 29 respectively provided in the first plate 26 and the second plate 28. When snails are placed or released into the snail breeding pond 2 for breeding, it is necessary to keep the water in the snail breeding pond 2 flowing at all times. So when the water in the snail breeding pond 2 flows, the water in the snail breeding pond 2 passes through the first arc-shaped hole 27 and the second arc-shaped hole 29 provided in the multiple folding plate components in sequence. This allows the water in the snail breeding pond 2 to flow from between two adjacent folded plate components in one group to between the first plate surface 26 and the second plate surface 28, and then to between two adjacent folded plate components in the next group. At the same time, the rootless duckweed floating on the surface of the water in the snail breeding pond 2 also passes through the first arc-shaped hole 27 and the second arc-shaped hole 29 in sequence, so that the first plate surface 26 and the second plate surface 28 of each folded plate component are attached or covered with rootless duckweed, so that the first plate surface 26 and the second plate surface 28 of each folded plate component have rootless duckweed that snails can climb on to eat, and so that each first plate surface 26 and the second plate surface 28 has snails.

[0039] This allows the partition mechanism to adjust the direction of water flow within the snail farming pond 2, and also increases the activity space for the snails within the pond 2, thus allowing more snails to be farmed in the pond 2 and making full use of the space, effectively increasing the yield of snail farming.

[0040] In a preferred embodiment, a snail partition 19 is provided at the top of the interior of the bottom slag collection hopper 3. Multiple bottom lighting components 20 are installed on the snail partition 19. The pores of the snail partition 19 are smaller than the snails but larger than the snails' excrement and discarded feed. After the snails are placed in the snail breeding pond 2, the snails will not fall into the bottom slag collection hopper 3. Instead, the snails' excrement and discarded feed can pass through the snail partition 19 and fall into the transparent collection tank 5 for unified collection. This reduces the workload of cleaning the snail breeding pond 2 and ensures the hygiene of the snail breeding pond 2.

[0041] In a preferred embodiment, a triangular prism support frame 21 is provided at the bottom of the bottom lighting component 20. Multiple lighting lamps 23 are mounted on the triangular prism support frame 21, and a transparent conical cover 22 is mounted on the outside of each lighting lamp 23. Both the triangular prism support frame 21 and the transparent conical cover 22 are mounted on the snail partition net 19, allowing snail excrement and discarded feed to slide down the inclined surfaces of the triangular prism support frame 21 and the transparent conical cover 22 when they fall onto them. This prevents the snail excrement and discarded feed from accumulating on the triangular prism support frame 21 and the transparent conical cover 22. The light emitted by the lighting lamp 23 installed on the triangular prism support frame 21 can illuminate the surface between the first plate surface 26 and the second plate surface 28 of each folding plate component, allowing the rootless duckweed attached to the surface between the first plate surface 26 and the second plate surface 28 of each folding plate component to photosynthesize. This prevents the plate surface connecting cylinder 24 on the folding plate component from blocking the light from above, thus preventing the rootless duckweed on the surface between the first plate surface 26 and the second plate surface 28 from photosynthesizing even during the day. Furthermore, the light from below illuminates the snails in the snail breeding pond 2, making it easier for staff to observe the snail breeding situation.

[0042] This allows the solid waste collection mechanism to prevent snails from falling into the bottom slag hopper 3, and also to collect snail excrement and uneaten food. After the snail excrement and uneaten food pass through the snail partition 19 and fall into the transparent collection tank 5 along the conical bottom slag hopper 3, the amount of snail excrement and uneaten food collected can be seen through the scale on the transparent collection tank 5. Once the amount is sufficient for treatment, simply insert or move the gate 4 inward to close the bottom of the bottom slag hopper 3, and then rotate the transparent collection tank 5 counterclockwise and loosen it. This allows the transparent collection tank 5, which is connected or installed by threads, to be disassembled, making it easier to treat the snail excrement and uneaten food collected in the transparent collection tank 5. This ensures the hygiene of the snail breeding pond 2, and multiple lights 23 can also illuminate the snail breeding pond 2, facilitating the photosynthesis of the rootless duckweed and the observation of the snail breeding pond 2, effectively demonstrating the convenience of the equipment.

[0043] In a preferred embodiment, a side wall connecting groove 17 is provided on the inner wall of the snail breeding pond 2 near the water pumping pipe 9. The side wall connecting groove 17 is connected to the water inlet of the water pumping pipe 9. A nutrient mesh 18 for separating rootless duckweed is embedded in the side wall connecting groove 17. The water in the snail breeding pond 2 flows from right to left, so the rootless duckweed put into the snail breeding pond 2 will also drift from right to left. The pores of the nutrient mesh 18 are smaller than those of the rootless duckweed, so that the water transmitted from the snail breeding pond 2 to the water pumping pipe 9 can pass through the nutrient mesh 18 and separate the rootless duckweed, preventing the rootless duckweed from entering the pipe and clogging it.

[0044] In summary, when using this invention, an appropriate amount of water is first added to the cleaned snail breeding pond 2. The water is then pumped by the suction force provided by the pump 6, causing the water pipe 9 to draw water from the snail breeding pond 2. The water pipe 9 can open or close the corresponding water valve 10 according to the liquid level in the snail breeding pond 2. Water pipes above the liquid level in the snail breeding pond 2 can close the corresponding water valve 10, while water pipes at or below the liquid level can keep the corresponding water valve 10 open. This allows water to be transferred from the water pipe 9 to the water transfer pipe 11, and then from the water transfer pipe 11 to the drainage transfer pipe 12. During the day, when there is sunlight and no duckweed (spirulina) is present, photosynthesis can occur. When in operation, the drainage branch valve 14 installed on the drainage branch pipe 13 can be opened, and the drainage valve 15 installed on the drainage transmission pipe 12 can also be closed or opened. This allows water in the drainage transmission pipe 12 to be transferred through the drainage branch pipe 13 to the rootless duckweed culture pond 1, allowing the rootless duckweed and water on the surface of the rootless duckweed culture pond 1 to flow through the nutrient transmission pipe 7 to the snail culture pond 2. Simultaneously, when the drainage valve 15 is closed, water in the drainage transmission pipe 12 will only be transferred from the drainage branch pipe 13 to the rootless duckweed culture pond 1. When the drainage valve 15 is opened, water in the drainage transmission pipe 12 can be transferred from the drainage branch pipe 13 to the rootless duckweed culture pond 1, and water in the drainage transmission pipe 12 can also... The water is directly transferred to the nutrient transfer pipe 7 and then further transferred to the snail breeding pond 2, causing the water in the snail breeding pond 2 to flow or transfer from right to left. At night or in the absence of light, the nutrient pipe valve 8 installed on the nutrient transfer pipe 7 and the drainage branch valve 14 installed on the drainage branch pipe 13 need to be closed in advance, while the drainage valve 15 installed on the drainage transfer pipe 12 needs to be opened. The suction force provided by the water pump 6 allows the water pumping pipe 9 to draw water from the snail breeding pond 2 into the pumping transfer pipe 11, then from the pumping transfer pipe 11 to the drainage transfer pipe 12, and finally from the drainage transfer pipe 12 to the nutrient transfer pipe 7. Because the nutrient pipe valve 8 installed on the nutrient transfer pipe 7 is located near the top... The water transported by the drainage pipe 12 is directly delivered to the middle part of the nutrient transport pipe 7 and then flows downward or is transported to the snail breeding pond 2. This allows the equipment to maintain the circulation of water in the snail breeding pond 2 even when the rootless duckweed is turned off, thereby increasing the oxygen content in the water in the snail breeding pond 2. This stops the transfer or delivery of rootless duckweed from the rootless duckweed breeding pond 1 to the snail breeding pond 2. Once the rootless duckweed in the snail breeding pond 2 is consumed by the snails or the number of them is reduced, the carbon dioxide produced by the rootless duckweed during plant respiration in the snail breeding pond 2 is reduced or eliminated. This prevents the snails from dying due to lack of oxygen caused by the absorption of oxygen and carbon dioxide during plant respiration, thus maintaining the flow of water in the snail breeding pond 2.

[0045] Then, according to the needs of production and aquaculture planning, the selected or screened snails are released into the snail breeding pond 2. Multiple support crossbars 30, with folding plate components inserted or installed, are erected on the front and rear rows of support blocks 16 in the snail breeding pond 2, thereby fixing the support crossbars 30 and the folding plate components. This allows the snails, which cannot swim in the water, to climb along the inner wall of the snail breeding pond 2 onto the first and second plates 26 and 28 of the multiple folding plate components to feed on the attached rootless duckweed. The multiple folding plate components installed in the snail breeding pond 2... The device allows duckweed to attach and stay, and allows snails to climb onto the first plate surface 26 and the second plate surface 28 of the folding plate component to eat the duckweed. It also provides snails with plenty of room to move around in the snail breeding pond 2, allowing more snails to be raised in the snail breeding pond 2 and reducing the waste of space in the snail breeding pond 2. When collecting snails in the snail breeding pond 2, the support crossbar 30 and the folding plate component can be removed, and most of the snails can be collected by simply scraping them off the first plate surface 26 and the second plate surface 28.

[0046] Next, the snails in the snail breeding pond 2 are separated by the snail partition net 19 set on the bottom slag collection hopper 3, and the snail excrement and waste feed can pass through the snail partition net 19 and fall into the transparent collection tank 5 for unified collection. At the same time, the light emitted by the light lamp 23 installed on the triangular column support frame 21 can illuminate the surface between the first plate surface 26 and the second plate surface 28 of each folding plate component, so that the rootless duckweed attached to the surface between the first plate surface 26 and the second plate surface 28 of each folding plate component can receive light and carry out photosynthesis. This prevents the plate surface connecting cylinder 24 set on the folding plate component from blocking the light from the top and bottom, so that the rootless duckweed on the surface between the first plate surface 26 and the second plate surface 28 cannot carry out photosynthesis even during the day. Moreover, the light lamp 23 illuminates from the bottom up, which makes it easier for staff to observe the snail breeding situation in the snail breeding pond 2.

[0047] Finally, by checking the scale on the transparent collection tank 5, you can determine the amount of snail excrement and uneaten food collected. Once you have collected enough for processing, simply insert or move the gate 4 inward to close the bottom of the bottom slag hopper 3. Then, rotate the transparent collection tank 5 counterclockwise and loosen it. This allows the transparent collection tank 5, which is connected or installed by threads, to be disassembled. This facilitates the processing of the snail excrement and uneaten food collected in the transparent collection tank 5, ensuring the hygiene of the snail breeding pond 2 and improving the yield and quality of snail farming.
