Description

Technical Field

[0001] This invention relates to the field of shrimp and silkworm co-culture technology, specifically to a shrimp and silkworm co-culture system. Background Technology

[0002] Shrimp-sandworm polyculture refers to the mixed culture of shrimp and sandworms. High-density shrimp farming in marine waters suffers from problems such as excessive uneaten feed and shrimp feces, high mortality rates, low yields and quality, and severe environmental pollution. However, polyculture of sandworms and shrimp allows the sandworms to feed on uneaten feed and shrimp excrement, effectively removing pollution and maintaining a good and stable farming environment. Sandworms belong to the phylum Annelida and are polychaete organisms rich in amino acids, trace elements, and polyunsaturated fatty acids such as EPA, which can promote the maturation of shrimp gonads, increase the number of fertilized eggs, and improve mating rates. To ensure that shrimp feces can flow to the sandworm's living area, the shrimp farming area is located above the sandworm area. However, to ensure that the sandworms have a sufficient growth cycle, a perforated plate is placed between the sandworms and shrimp, through which shrimp feces reach the sandworm area.

[0003] The conventional farming method involves catching shrimp, draining the water, manually digging out sandworms, and then feeding the sandworms to the shrimp. This makes it difficult for shrimp to catch sandworms naturally during the farming process, which greatly affects the efficiency of shrimp gonad maturation and results in low efficiency of sandworms feeding back to the shrimp population in polyculture. To address these issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a shrimp and silkworm polyculture system, including a base, a metal cage fixedly connected to the top of the base, a partition cage fixedly connected to the inner wall of the metal cage, and a top plate fixedly connected to the end of the metal cage away from the base, and further including:

[0005] The drive mechanism is fixedly connected to the top of the top plate and is used to drive the equipment to move the sandworms at the bottom to the shrimp farming area at the top.

[0006] The pressure mechanism, located at the top of the base, is used to collect shrimp feces and uneaten feed.

[0007] The driving mechanism is fixedly installed on the outer wall of the pressure mechanism to absorb the pressure generated by the movement of the pressure mechanism and generate enough bubbles to drive away the shrimp.

[0008] Before use, the base is fixed in the desired position. Then, the silt is made to cover one-third of the area of ​​the metal cage. The sandworms are then placed in the silt area 15 days in advance.

[0009] Preferably, the drive mechanism includes:

[0010] The power assembly is fixedly installed on the top of the top plate;

[0011] The storage component is fixedly connected to the top of the base by fasteners;

[0012] The fastener includes a fixing rod fixedly connected to the top of the base, a partition fixedly connected to the end of the fixing rod away from the base, and a storage tube slidably connected to the outer wall of the partition;

[0013] The power unit will drive the pressure mechanism and the driving mechanism upwards, and bring some sandworms and silt to the shrimp farming area.

[0014] Preferably, the pressure mechanism includes:

[0015] The obstruction component is fixedly connected to the top of the storage tube via a collection component;

[0016] The collection component includes a collection plate that runs through the top of the storage tube;

[0017] The pressure-bearing component is fixedly connected to the bottom of the inner wall of the top plate via a transmission component;

[0018] The transmission component includes a telescopic tube fixedly connected to the bottom of the top plate;

[0019] When the power component drives the pressure mechanism and the driving mechanism to move up and down, the telescopic tube will extend or contract accordingly.

[0020] Preferably, the driving mechanism includes:

[0021] Bubble assembly, the bubble assembly is fixedly connected to the outer wall of the collecting plate;

[0022] Auxiliary components are fixedly mounted on the outer wall of the storage components;

[0023] When the pressure-bearing component is pressurized, the air inside the pressure-bearing component will be ejected outward through the bubble component to drive away the shrimp outside.

[0024] Preferably, the power assembly includes a drive motor fixedly connected to the top of the top plate, a telescopic rod fixedly connected to the outer wall of the drive motor, and a fixing frame fixedly connected to the end of the telescopic rod away from the drive motor.

[0025] When in use, the drive motor generates a contraction force, which drives the fixed frame to move upward through the telescopic rod.

[0026] Preferably, the storage component includes a grid formed on the outer wall of the storage tube;

[0027] When the shrimp at the top of the partition cage produce feces, the feces will fall downwards, most of which will pass through the partition cage, while some will be intercepted by the collection plate and enter the inner wall of the storage tube.

[0028] Preferably, the obstruction component includes a through hole formed in the outer wall of the storage tube, and a load-bearing frame is fixedly connected to the outer wall of the through hole;

[0029] The width of the through hole is smaller than that of the sandworm's body, which prevents the sandworm from passing through the through hole. The sandworm can only crawl on top of the support frame and insert its mouthparts into the through hole to feed.

[0030] Preferably, the pressure-bearing component includes an air inlet check valve one that is connected through to the top of the telescopic pipe, and an exhaust check valve two that is fixedly connected to the end of the telescopic pipe away from the air inlet check valve one.

[0031] When the telescopic rod moves the fixed frame upward, the telescopic tube will be squeezed and the gas inside the telescopic tube will be ejected.

[0032] Preferably, the bubble assembly includes a transmission pipe that is connected through to the outer wall of the exhaust check valve, four output pipes that are connected through to the bottom of the transmission pipe, and bubble nozzles that are connected through to the output ends of the output pipes.

[0033] The gas sprayed from the telescopic tube is transmitted to the output tube through the transmission tube, and then sprayed downwards in the form of fine bubbles through the bubble nozzle to drive away the shrimp.

[0034] Preferably, the auxiliary components include a circular scraper fixedly connected to the bottom of the partition, and a blocking plate fixedly connected to the outer wall of the storage tube;

[0035] The bottom of the blocking plate is connected to the bottom of the storage tube. When the storage tube moves upward, the feces at the bottom of the storage tube will fall downward.

[0036] The present invention has the following beneficial effects:

[0037] (1) This invention addresses the problem of low feeding efficiency of sandworms and shrimp populations by incorporating a pressure mechanism inside the equipment. After a period of feeding, the operator can connect the power supply to the drive motor, causing the drive motor to move the fixed frame upwards via the telescopic rod. The fixed frame will then move the collection plate upwards synchronously, and the sandworms and silt at the top of the load-bearing frame will move upwards synchronously along with the collection plate and storage pipe, presenting a situation as follows: Figure 9 In this state, the final output pipe will be sealed at the through hole of the partition cage. Through the application of the above components, after a certain period of feeding, some mature sandworms will be brought to the shrimp farming area, avoiding the conventional process of pumping water and manually digging up sandworms, and improving the feeding efficiency of sandworms to shrimp groups during polyculture.

[0038] (2) The present invention utilizes the feature that the collection plate drives the storage tube to move upward synchronously. A fixed rod and a circular scraper are installed inside the device. When the collection plate moves upward, the partition is stationary due to the influence of the fixed rod. This causes the partition and the circular scraper to slide along the inner wall of the storage tube when the storage tube moves upward. Since the inside of the storage tube is filled with food residue and feces, the circular scraper will scrape off the residue inside the storage tube when the storage tube moves upward, and cause the impurities to accumulate inside the silt pit. This effectively prevents the storage tube from being blocked due to excessive impurities, which would affect the processing efficiency of sandworm and shrimp feces.

[0039] (3) The present invention utilizes the above-mentioned characteristic of the storage tube moving upward and sets up a blocking plate inside the equipment. The initial position of the blocking plate is at the bottom of the sludge. When the storage tube moves upward, the blocking plate will move upward synchronously. This allows the blocking plate to carry some sludge upward synchronously. At this time, due to the poor support of the sludge itself, when the blocking plate moves part of the sludge upward, several hollow deep pits will appear in the center of the sludge. This causes the surrounding sludge to slowly gather towards the deep pits. During the gathering process, the sludge will completely wrap around the outer wall of the remaining food residue. As the sludge flows, the bottom sludge can be exposed to the water, preventing the bottom sludge from lacking oxygen.

[0040] (4) The present invention utilizes the feature of the fixed frame moving up and down, and sets up a bubble assembly and a pressure assembly inside the device. When the fixed frame moves up, the telescopic tube will be compressed and contract. The gas sprayed out of the telescopic tube is transmitted to the output tube through the transmission tube, and sprayed downward in the form of small bubbles through the bubble nozzle to drive away the shrimp. Through the application of the above components, it is prevented that too many shrimp will enter the bottom mud area due to the large opening at the top of the partition cage during the upward movement of the mud and sandworms, which would affect the growth efficiency of the sandworms.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1, please refer to Figures 1-4 This invention is a shrimp and silkworm polyculture system, including a base 13, a metal cage 14 fixedly connected to the top of the base 13, a partition cage 15 fixedly connected to the inner wall of the metal cage 14, and a top plate 16 fixedly connected to the end of the metal cage 14 away from the base 13, and also including:

[0056] Drive mechanism 1 is fixedly connected to the top of top plate 16 and is used to drive the equipment to move the sandworms at the bottom to the shrimp farming area at the top.

[0057] Pressure mechanism 2 is located on top of base 13 and is used to collect shrimp feces and uneaten feed.

[0058] The driving mechanism 3 is fixedly installed on the outer wall of the pressure mechanism 2. It is used to absorb the pressure generated by the movement of the pressure mechanism 2 and generate enough bubbles to drive away the shrimp.

[0059] Before use, the base 13 is fixed in the desired position. Then, the silt is made to cover one-third of the area of ​​the metal cage 14. The sandworms are placed in the silt area 15 days in advance. The shrimp larvae are then placed in the top area of ​​the partition cage 15 and fed normally.

[0060] Drive mechanism 1 includes:

[0061] Power assembly 11, which is fixedly mounted on the top of the top plate 16;

[0062] Storage component 12 is fixedly connected to the top of base 13 by a fastener;

[0063] The fastener includes a fixing rod 121 fixedly connected to the top of the base 13, a partition 122 fixedly connected to the end of the fixing rod 121 away from the base 13, and a storage tube 123 slidably connected to the outer wall of the partition 122.

[0064] During the feeding process, most of the shrimp debris and feces will pass through the barrier cage 15 and fall onto the top of the silt, where the sandworms will digest the excess food residue and feces.

[0065] Among them, the power component 11 will drive the pressure mechanism 2 and the driving mechanism 3 to move upward, and drive some sandworms and silt to the shrimp farming area.

[0066] Pressure mechanism 2 includes:

[0067] Obstruction component 21 is fixedly connected to the top of storage tube 123 via a collection component;

[0068] The collection component includes a collection plate 211 that is connected through to the top of the storage tube 123;

[0069] The pressure-bearing component 22 is fixedly connected to the bottom of the inner wall of the top plate 16 via a transmission component;

[0070] The transmission component includes a telescopic tube 221 fixedly connected to the bottom of the top plate 16;

[0071] Some of the residue and feces will fall onto the top of the collection plate 211 and along the inner wall of the collection plate 211 onto the inner wall of the storage tube 123. This results in the amount of food in the silt area at the bottom of the metal cage 14, near the storage tube 123, being much higher than in other areas. This allows the sandworms that gather on the outer wall of the storage tube 123 to get more food and grow faster than in other areas.

[0072] When the power component 11 drives the pressure mechanism 2 and the driving mechanism 3 to move up and down, the telescopic tube 221 will extend or contract accordingly.

[0073] The driving mechanism 3 includes:

[0074] Bubble assembly 31 is fixedly connected to the outer wall of collecting plate 211;

[0075] Auxiliary component 32 is fixedly disposed on the outer wall of storage component 12;

[0076] When the pressure-receiving component 22 is pressurized, the air inside the pressure-receiving component 22 will be ejected outward through the bubble component 31 to drive away the shrimp outside.

[0077] Example 2, please refer to Figures 3-10 The present invention is a shrimp and silkworm polyculture system. Based on Example 1, the power component 11 includes a drive motor 111 fixedly connected to the top of the top plate 16, a telescopic rod 112 fixedly connected to the outer wall of the drive motor 111, and a fixed frame 113 fixedly connected to the end of the telescopic rod 112 away from the drive motor 111.

[0078] When in use, the drive motor 111 generates a contraction force, which drives the fixed frame 113 to move upward through the telescopic rod 112.

[0079] Storage component 12 includes a grid 124 formed on the outer wall of storage tube 123;

[0080] When the shrimp at the top of the partition cage 15 produce feces, the feces will fall downwards, most of which will pass through the partition cage 15, while some will be intercepted by the collection plate 211 and enter the inner wall of the storage tube 123.

[0081] The obstruction component 21 includes a through hole 212 opened on the outer wall of the storage tube 123, and a load-bearing frame 213 is fixedly connected to the outer wall of the through hole 212.

[0082] The width of the through hole 212 is smaller than that of the sandworm body, which prevents the sandworm from passing through the through hole 212. The sandworm can only crawl on the top of the load-bearing frame 213 and insert its mouthparts into the through hole 212 to feed.

[0083] The pressure-bearing component 22 includes an inlet check valve 222 that is connected through to the top of the telescopic pipe 221, and an exhaust check valve 223 that is fixedly connected to the end of the telescopic pipe 221 away from the inlet check valve 222.

[0084] When the telescopic rod 112 drives the fixed frame 113 to move upward, the telescopic tube 221 will be squeezed and the gas inside the telescopic tube 221 will be ejected.

[0085] The bubble assembly 31 includes a transmission pipe 311 that is connected through to the outer wall of the exhaust one-way valve 223. Four output pipes 312 are connected through to the bottom of the transmission pipe 311, and bubble nozzles 313 are connected through to the output ends of the output pipes 312.

[0086] After a period of feeding, the staff can connect the power to the drive motor 111, causing the drive motor 111 to drive the fixed frame 113 upward via the telescopic rod 112. The fixed frame 113 will then drive the collection plate 211 upward synchronously. The sandworms and silt at the top of the load-bearing frame 213 will move upward synchronously along with the collection plate 211 and the storage pipe 123, presenting a scene as follows. Figure 9 In this state, the final output pipe 312 will be blocked at the through hole of the partition cage 15. Through the application of the above components, after a certain period of feeding, some mature sandworms will be brought to the shrimp farming area, avoiding the conventional process of pumping water and manually digging up sandworms, and improving the feeding efficiency of sandworms to shrimp groups during the polyculture process.

[0087] Taking advantage of the vertical movement of the aforementioned fixed frame 113, an air bubble assembly 31 and a pressure-bearing assembly 22 are installed inside the device. When the fixed frame 113 moves upward, the telescopic tube 221 will be compressed and contract. The gas sprayed out of the telescopic tube 221 is transmitted to the output tube 312 through the transmission tube 311, and then sprayed downward in the form of fine bubbles through the air bubble nozzle 313 to drive away the shrimp. Through the application of the above-mentioned components, it is prevented that too many shrimp will enter the bottom mud area due to the large opening at the top of the partition cage 15 during the upward movement of the silt and sandworms, which would affect the growth efficiency of the sandworms.

[0088] The auxiliary component 32 includes a circular scraper 321 fixedly connected to the bottom of the partition 122, and a blocking plate 322 fixedly connected to the outer wall of the storage tube 123;

[0089] The bottom of the blocking plate 322 is connected to the bottom of the storage tube 123. When the storage tube 123 moves upward, the feces at the bottom of the storage tube 123 will fall downward.

[0090] Taking advantage of the characteristic that the collection plate 211 drives the storage tube 123 to move upward synchronously, a fixed rod 121 and a circular scraper 321 are installed inside the equipment. When the collection plate 211 moves upward, the partition 122 remains stationary due to the influence of the fixed rod 121. This causes the partition 122 and the circular scraper 321 to slide along the inner wall of the storage tube 123 when the storage tube 123 moves upward. Since the inside of the storage tube 123 is filled with food residue and feces, the circular scraper 321 will scrape off the residue inside the storage tube 123 when the storage tube 123 moves upward, and cause the impurities to accumulate inside the sludge pit, effectively preventing excessive impurities from remaining in the storage tube 123 and causing blockage of the storage tube 123.

[0091] Taking advantage of the upward movement of the storage pipe 123, a blocking plate 322 is installed inside the device. The initial position of the blocking plate 322 is at the bottom of the sludge. When the storage pipe 123 moves upward, the blocking plate 322 will move upward synchronously. This allows the blocking plate 322 to carry some of the sludge upward. At this time, due to the poor support of the sludge itself, when part of the sludge moves upward through the blocking plate 322, several hollow pits will appear in the center of the sludge. This causes the surrounding sludge to slowly gather towards the pits. During the gathering process, the sludge will completely cover the outer wall of the remaining food residue. As the sludge flows, the bottom sludge can be exposed to the water, preventing the bottom sediment from becoming oxygen-deficient.

[0092] One specific application of this embodiment is as follows: Before use, fix the base 13 in the desired position, then ensure that the silt covers one-third of the area of ​​the metal cage 14, and then put the sandworms into the silt area 15 days in advance. After 15 days, put the shrimp larvae into the top area of ​​the partition cage 15 and feed them normally.

[0093] During the feeding process, most of the shrimp debris and feces will pass through the partition cage 15 and fall onto the top of the silt, where the sandworms will digest the excess food residue and feces.

[0094] Some of the residue and feces will fall onto the top of the collection plate 211 and along the inner wall of the collection plate 211 onto the inner wall of the storage tube 123. This results in the amount of food in the silt area at the bottom of the metal cage 14, near the storage tube 123, being much higher than in other areas. This allows the sandworms that gather on the outer wall of the storage tube 123 to obtain more food and grow faster than in other areas.

[0095] When the sandworm reaches the outer wall of the storage tube 123, the width of the through hole 212 is smaller than the sandworm body, which makes it impossible for the sandworm to pass through the through hole 212. The sandworm can only crawl on the top of the support frame 213 and put its mouthparts into the through hole 212 to feed.

[0096] After a period of feeding, the staff can connect the power to the drive motor 111, causing the drive motor 111 to drive the fixed frame 113 upward via the telescopic rod 112. The fixed frame 113 will then drive the collection plate 211 upward synchronously. The sandworms and silt at the top of the load-bearing frame 213 will move upward synchronously along with the collection plate 211 and the storage pipe 123, presenting a scene as follows. Figure 9 In this state, the final output pipe 312 will be blocked at the through hole of the partition cage 15. Through the application of the above components, after a certain period of feeding, some mature sandworms will be brought to the shrimp farming area, avoiding the conventional process of pumping water and manually digging up sandworms, and improving the feeding efficiency of sandworms to shrimp groups during polyculture.

[0097] Taking advantage of the characteristic that the collection plate 211 drives the storage tube 123 to move upward synchronously, a fixed rod 121 and a circular scraper 321 are installed inside the equipment. When the collection plate 211 moves upward, the partition 122 remains stationary due to the influence of the fixed rod 121. This causes the partition 122 and the circular scraper 321 to slide along the inner wall of the storage tube 123 when the storage tube 123 moves upward. Since the inside of the storage tube 123 is filled with food residue and feces, the circular scraper 321 will scrape off the residue inside the storage tube 123 as the storage tube 123 moves upward, causing the impurities to accumulate inside the silt pit, effectively preventing excessive impurities from remaining in the storage tube 123 and causing blockage of the storage tube 123.

[0098] Taking advantage of the upward movement of the storage pipe 123, a blocking plate 322 is installed inside the device. The initial position of the blocking plate 322 is at the bottom of the sludge. When the storage pipe 123 moves upward, the blocking plate 322 will move upward synchronously. This allows the blocking plate 322 to carry some of the sludge upward. At this time, due to the poor support of the sludge itself, when part of the sludge moves upward through the blocking plate 322, several hollow pits will appear in the center of the sludge. This causes the surrounding sludge to slowly gather towards the pits. During the gathering process, the sludge will completely cover the outer wall of the remaining food residue. As the sludge flows, the bottom sludge can be exposed to the water, preventing the bottom sediment from becoming oxygen-deficient.

[0099] Taking advantage of the vertical movement of the aforementioned fixed frame 113, an air bubble assembly 31 and a pressure-bearing assembly 22 are installed inside the device. When the fixed frame 113 moves upward, the telescopic tube 221 will be compressed and contract. The gas sprayed out of the telescopic tube 221 is transmitted to the output tube 312 through the transmission tube 311, and then sprayed downward in the form of fine bubbles through the air bubble nozzle 313 to drive away the shrimp. Through the application of the above-mentioned components, it is prevented that too many shrimp will enter the bottom mud area due to the large opening at the top of the partition cage 15 during the upward movement of the silt and sandworms, which would affect the growth efficiency of the sandworms.
