Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture technology, specifically to a feeding device and method for factory-scale eel farming. Background Technology
[0002] Aquaculture, as an important part of modern agriculture, is a farming model that achieves full-process control over the reproduction, cultivation, growth, and harvesting of aquatic products by artificially creating a breeding environment and precisely controlling growth conditions. Its core objective is to improve the yield and quality of aquatic products and meet market supply and demand. Aquatic products cover a wide range of categories, including fish, crustaceans, amphibians, and many others. Eels, as a freshwater fish with both edible and economic value, are one of the common species in aquaculture.
[0003] In the process of large-scale eel farming, feeding management is a key factor affecting the growth rate and health of eels. Farmers need to scientifically formulate special compound feed or live insects (such as earthworms and fly larvae) according to the growth stage and feeding habits of eels. Among them, compound feed is widely used in large-scale eel farming due to its advantages such as balanced nutrition, convenient feeding and controllable cost. In order to achieve orderly storage of feed and avoid waste and pollution, the farming site is usually equipped with special feed containers to seal the compound feed inside the containers, so as to facilitate on-demand and precise feeding.
[0004] However, due to various factors, compound feed stored in feed hoppers is prone to clumping and fermentation. From the perspective of the feed's characteristics, compound feed is mostly made from a mixture of raw materials such as grain flour, fish meal, soybean meal, and mineral additives. Some of these raw materials have strong hygroscopic properties. If the feed hopper is not well sealed, moisture from the outside air will seep into the hopper, causing the feed particles to absorb moisture and stick together, gradually forming clumps of varying sizes. This affects the feed's flowability and feeding effect. At the same time, aquaculture sites are mostly located in humid and warm environments. The humid environment and suitable temperature inside the feed hopper provide excellent breeding conditions for residual microorganisms (such as molds and yeasts). During the process of the large-scale proliferation of microorganisms, they decompose the nutrients in the feed, producing a fermentation reaction. This not only destroys the core nutrients such as proteins and vitamins in the feed, leading to a significant decrease in the feed's nutritional value, but also produces harmful substances such as organic acids and ammonia, causing the feed to have an off-odor and spoil.
[0005] Therefore, the present invention provides a feeding device and method for industrialized eel farming to solve the above-mentioned problems. Summary of the Invention
[0006] In order to overcome the shortcomings of the prior art, the present invention provides a feeding device and method for industrialized eel farming, which solves the problem that the feed will clump together and ferment to produce gas when it is inside the feed drum for a long time.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A feeding device for factory-scale eel farming includes a feed cylinder and a stirring mechanism; The outer wall of the barrel is equipped with a feed inlet for feeding, and the feed inlet is fixedly connected to the outer wall of the barrel. The material will fall into the inside of the barrel through the inclined guide of the feed inlet, so that the material is stirred and mixed inside the barrel. The mixing mechanism includes a connector, which includes multiple bosses and connecting blocks. The bosses and connecting blocks are all annular. The connecting blocks have grooves, and the tops of the corresponding bosses are slidably connected inside the grooves of the connecting blocks. The multiple bosses and connecting blocks are arranged alternately in sequence, and the multiple bosses and connecting blocks are arranged vertically along the axial direction of the bosses. The tops of the bosses are fixed to the bottoms of the connecting blocks located above. Side shafts are symmetrically installed on the outside of the bosses, and spiral blades are installed on the outside of the side shafts. When the connector rotates, the side shafts and spiral blades can mix and crush the material inside the barrel.
[0008] Preferably, two first limiting blocks are symmetrically fixed to the outer wall of one end of the boss located inside the connecting block, and two first limiting grooves adapted to the first limiting blocks are symmetrically opened on the inner wall of the connecting block. The first limiting blocks are slidably connected inside the corresponding first limiting grooves. The first limiting blocks cooperate with the first limiting grooves to limit the boss and maintain the stability of the boss.
[0009] Preferably, a top shaft is fixed to the top of the connector, a connecting ring is installed on the outside of the top shaft, and the outer wall of the connecting ring is rotatably connected to the inner wall of the barrel. Multiple fixing plates are fixed to the inner wall of the connecting ring at equal intervals and arranged in a ring on the inner wall of the connecting ring. The fixing plates are provided with limiting holes that are adapted to the top shaft. The fixing plates correspond one-to-one with the connector, and the limiting holes are coaxial with the top shaft. The outer wall of the top shaft is rotatably connected to the inner wall of the limiting holes. The fixing plates are used to support the top shaft and the connector, thereby maintaining the stability of the connector.
[0010] Preferably, a first external toothed ring is installed on the outside of the top shaft, and the outer wall of the first external toothed ring is fixed on the inner wall of the material cylinder. The first external toothed ring is meshed with the toothed ring. When the connecting ring rotates around its axial direction, the first external toothed ring can drive the connecting piece to rotate around its axial direction through meshing with the toothed ring, so that the side shaft and the spiral cutter can stir and crush the material inside the material cylinder.
[0011] Preferably, the material cylinder is provided with a compression mechanism inside. The compression mechanism includes a limiting shaft disposed inside the material cylinder and coaxially disposed with the material cylinder. A side plate is fixed between the outer wall of the limiting shaft and the inner wall of the connecting ring to support the connecting ring and maintain its stability. A drive source is installed on the top of the material cylinder, and the output end of the drive source is fixed to the top of the limiting shaft. The output end of the drive source can drive the limiting shaft to rotate around its axis. The limiting shaft drives the connecting ring to rotate through the side plate, thereby driving the connecting parts to rotate and stir and crush the material.
[0012] Preferably, a guide plate is provided on the outer side of the bottom end of the limiting shaft. The guide plate is conical in shape, and a circular hole adapted to the limiting shaft is opened on the top of the guide plate. The limiting shaft is slidably connected to the surface of the limiting shaft through the circular hole. The material can be guided to the connecting part by the inclined surface of the outer wall of the guide plate, so that the connecting part can stir and crush the material.
[0013] Preferably, a lifting cylinder is fixed to the inner wall of the circular hole, and the inner wall of the lifting cylinder is slidably connected to the outside of the limiting shaft, and the limiting shaft and the lifting cylinder are coaxially arranged. A base plate is fixed to the bottom of the material cylinder, a linkage component is fixed to the top of the base plate, and the linkage component is located inside the guide plate. A drive shaft is fixed inside the guide plate, and the drive shaft is slidably connected to the surface of the linkage component.
[0014] Preferably, a limiting ring is fixed at the bottom of the guide plate, and an annular hole adapted to the limiting ring is opened at the bottom of the material cylinder. The outer wall of the limiting ring is attached to the inner wall of the annular hole, and the limiting ring is slidably connected inside the annular hole. Multiple side support plates are fixed at equal intervals on the outer wall of the guide plate, and the side support plates correspond one-to-one with the connecting parts. The bottom of the connecting parts is rotatably connected to the top of the corresponding side support plates. A second limiting block is fixed inside the lifting cylinder. A second limiting groove adapted to the second limiting block is opened on the outer wall of the limiting shaft, and the second limiting block is slidably connected inside the second limiting groove. The second limiting block and the second limiting groove are used to limit the guide plate.
[0015] Preferably, the material cylinder is equipped with a crushing mechanism, which includes a linkage shaft disposed inside the boss, with both ends of the linkage shaft fixed to one side wall of a corresponding side shaft, and the side shaft and the linkage shaft being coaxially arranged. A second external toothed ring is installed on the outside of the linkage shaft. A lifting shaft is fixed to the inner top wall of the connecting block. A through hole adapted to the lifting shaft is opened on the boss, and the lifting shaft and the through hole are coaxially arranged. The lifting shaft is slidably connected inside the through hole. A rack is fixed to the bottom of the lifting shaft, and the rack is meshed with the second external toothed ring. A return spring is fixed between the top of the boss and the inner top wall of the connecting block to support the boss and drive the released boss to return to its original position.
[0016] A feeding method for factory-scale eel farming includes the following steps: Step 1: Pour the material into the inside of the feed cylinder through the feed inlet; Step 2: Turn on the drive source. The drive source drives the connecting ring to rotate through the limit shaft and the side plate. The first outer toothed ring, in conjunction with the toothed ring, drives the connecting parts to rotate, so that the side shaft and the spiral cutter can stir and crush the material inside the barrel. Step 3: The material after mixing and crushing can be discharged through the open discharge port.
[0017] The beneficial effects of this invention are as follows: 1. The feed inlet is fixedly connected to the outer wall of the feed cylinder, forming a natural guiding slope. After the material is put in, it can slide smoothly into the feed cylinder along the inclined surface by its own gravity without manual assistance. The feed cylinder has multiple discharge ports arranged in a ring at equal intervals at the bottom. Compared with a single discharge port, it can make the crushed material evenly discharged from different directions of the feed cylinder, which can meet the needs of multi-area feeding in factory farming. At the same time, the exhaust device equipped at the top of the feed cylinder can discharge the gas generated during the mixing and fermentation of the material in real time, effectively preventing the gas pressure inside the cylinder from being too high and squeezing the material, avoiding the material from clumping and hardening or the discharge from being obstructed. It can also prevent the gas pressure from being too high and causing damage to the feed cylinder structure, ensuring the long-term stable operation of the equipment and providing support for the continuity of feeding operations.
[0018] 2. Through the alternating arrangement and sliding engagement of the bosses and connecting blocks, an adjustable multi-layer mixing structure is formed. Combined with the spiral blades on the side shaft, it can perform all-round mixing and crushing of the material in the barrel. Through the meshing engagement of the first outer toothed ring and the toothed ring, the connecting ring drives the top shaft and connecting parts to rotate around their own axis while driving the connecting parts to slide circumferentially. This compound motion allows the spiral blades on the side shaft to not only move in a circular motion with the connecting parts, covering a larger mixing range in the barrel, but also to enhance the cutting and crushing force of the material through axial rotation. Compared with mixing in one direction, it can significantly improve the uniformity of material mixing and crushing efficiency, making the nutrient distribution of the mixed bait more uniform and the particle size of the crushed material more consistent, providing stable quality bait for eels.
[0019] 3. Through the cooperation of the linkage and drive shaft, the guide plate is automatically raised and lowered, which in turn drives the entire stirring mechanism to move upward. This allows for the stirring and crushing of materials at different height levels within the cylinder, effectively covering the internal space of the cylinder and preventing material from accumulating in layers. This ensures that all materials are fully processed. When the drive shaft slides from the bottom to the peak, the guide plate drives the side support plate and protrusions to move upward, causing multiple protrusions to close sequentially along the grooves of the connecting block, reducing the gap between the protrusions and allowing the spiral cutter to perform fine cutting on the material, thus improving the degree of crushing. When the drive shaft slides from the peak to the bottom, the protrusions move away sequentially under the action of the return spring, restoring the initial stirring range. This reciprocating closing and moving motion not only enables dynamic adjustment of the crushing precision but also causes the material in the cylinder to tumble up and down, preventing local material retention and completely eliminating the problem of material clumping. This ensures that each batch of feed meets the requirements for looseness and particle size for feeding.
[0020] 4. Through the meshing transmission between the rack and the second outer toothed ring, the spiral cutter achieves a dual motion of "revolution + rotation": while the spiral cutter revolves around the connecting part, during the lifting and lowering of the boss, the rack drives the second outer toothed ring and the linkage shaft to rotate, which in turn drives the spiral cutter to rotate itself. This dual crushing mode can significantly improve the crushing strength of materials, and can thoroughly crush high-hardness bait particles and fibrous materials into fine and uniform small particles, which is not only convenient for eels to feed on, but also promotes the digestion and absorption of nutrients from the bait, reduces the probability of intestinal diseases, and improves the survival rate and growth rate of eels. At the same time, the fine bait can reduce the deposition of residual bait at the bottom of the breeding pond, reduce the risk of water pollution, and alleviate the pressure of water quality maintenance in factory farming.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0024] As attached Figures 1-6 As shown, a feeding device for factory-scale eel farming includes a feed cylinder 10. The outer wall of the feed cylinder 10 is equipped with a feed inlet 11 for feeding. The feed inlet 11 is fixedly connected to the outer wall of the feed cylinder 10 and is inclined. The bottom end of the feed inlet 11 is fixedly connected to the outer wall of the feed cylinder 10. When material is poured into the feed inlet 11, the material will fall into the inside of the feed cylinder 10 through the inclined guide of the feed inlet 11, so that the material is stirred and mixed inside the feed cylinder 10 to facilitate subsequent feeding operations.
[0025] The bottom of the material cylinder 10 is fixedly connected to multiple discharge ports 12 arranged at equal intervals. The multiple discharge ports 12 are arranged in a ring at the bottom of the material cylinder 10. The inside of the material cylinder 10 can be connected to the outside through the discharge ports 12. The material inside the material cylinder 10 can be discharged through the discharge ports 12. The top of the material cylinder 10 is equipped with an exhaust device 13, which can discharge the gas inside the material cylinder 10 and prevent the gas inside the material cylinder 10 from being too high.
[0026] The material cylinder 10 is equipped with a stirring mechanism 20, which is used to stir and crush the material inside the stirring mechanism 20 to prevent the material from clumping and being unable to be discharged through the discharge port 12.
[0027] The stirring mechanism 20 includes a connector 21 disposed inside the material cylinder 10. The connector 21 includes multiple bosses 2101 and connecting blocks 2102, and both the bosses 2101 and the connecting blocks 2102 are annular. The connecting blocks 2102 have grooves, and the tops of the corresponding bosses 2101 are slidably connected to the grooves of the connecting blocks 2102. The multiple bosses 2101 and connecting blocks 2102 are arranged alternately in sequence, and the multiple bosses 2101 and connecting blocks 2102 are arranged vertically along the axial direction of the bosses 2101. The tops of the bosses 2101 are fixed to the bottoms of the connecting blocks 2102 located above.
[0028] Two first limiting blocks 22 are symmetrically fixed on the outer wall of one end of the boss 2101 located inside the connecting block 2102. Two first limiting grooves 23 adapted to the first limiting blocks 22 are symmetrically opened on the inner wall of the connecting block 2102. The first limiting blocks 22 are slidably connected inside the corresponding first limiting grooves 23. The first limiting blocks 22 cooperate with the first limiting grooves 23 to limit the boss 2101 and maintain the stability of the boss 2101.
[0029] A side shaft 24 is symmetrically installed on the outside of the boss 2101, and a spiral cutter 25 is installed on the outside of the side shaft 24. When the connecting piece 21 rotates, the side shaft 24 and the spiral cutter 25 can stir and crush the material inside the material cylinder 10, thereby preventing the material from clumping and being unable to be discharged through the discharge port 12.
[0030] A top shaft 26 is fixed to the top of the connector 21. A connecting ring 27 is installed on the outside of the top shaft 26, and the outer wall of the connecting ring 27 is rotatably connected to the inner wall of the material cylinder 10. Multiple fixing plates 28 are fixed on the inner wall of the connecting ring 27 at equal intervals, and the multiple fixing plates 28 are arranged in a ring on the inner wall of the connecting ring 27. The fixing plates 28 are provided with limiting holes 211 that are adapted to the top shaft 26. The fixing plates 28 correspond one-to-one with the connector 21, and the limiting holes 211 are coaxially set with the top shaft 26. The outer wall of the top shaft 26 is rotatably connected to the inner wall of the limiting holes 211. The fixing plates 28 are used to support the top shaft 26 and the connector 21, thereby maintaining the stability of the connector 21.
[0031] The top shaft 26 is equipped with a first external toothed ring 29, and the outer wall of the first external toothed ring 29 is fixed on the inner wall of the material cylinder 10. The first external toothed ring 29 is meshed with the toothed ring 210. When the connecting ring 27 rotates around its axial direction, the first external toothed ring 29 can drive the connecting piece 21 to rotate around its axial direction through the meshing connection with the toothed ring 210, so that the side shaft 24 and the spiral cutter 25 can stir and crush the material inside the material cylinder 10.
[0032] The material cylinder 10 is equipped with a compression mechanism 30, which can drive the connecting piece 21 to move upward, thereby increasing the crushing area of the material by the stirring mechanism 20. At the same time, it can also compress the gas generated by the material inside the material cylinder 10, thereby preventing the gas generated by the material from accumulating inside the material cylinder 10.
[0033] The compression mechanism 30 includes a limiting shaft 31 disposed inside the material cylinder 10 and coaxially disposed with the material cylinder 10. A side plate 32 is fixed between the outer wall of the limiting shaft 31 and the inner wall of the connecting ring 27 to support the connecting ring 27 and maintain its stability. A drive source 33 is installed on the top of the material cylinder 10 and the output end of the drive source 33 is fixed to the top of the limiting shaft 31. The output end of the drive source 33 can drive the limiting shaft 31 to rotate around its axis. The limiting shaft 31 drives the connecting ring 27 to rotate through the side plate 32, thereby driving the connecting piece 21 to rotate and stir and crush the material.
[0034] A guide plate 34 is provided on the outer side of the bottom end of the limiting shaft 31. The guide plate 34 is conical in shape. A circular hole adapted to the limiting shaft 31 is opened on the top of the guide plate 34. The limiting shaft 31 is slidably connected to the surface of the limiting shaft 31 through the circular hole. The material can be guided to the connecting member 21 by the inclined surface of the outer wall of the guide plate 34, so that the connecting member 21 can stir and crush the material.
[0035] A lifting cylinder 35 is fixed to the inner wall of the circular hole, and the inner wall of the lifting cylinder 35 is slidably connected to the outside of the limiting shaft 31. The limiting shaft 31 and the lifting cylinder 35 are coaxially arranged. A base plate 37 is fixed to the bottom of the material cylinder 10. A linkage 36 is fixed to the top of the base plate 37. The linkage 36 is located inside the guide plate 34. A drive shaft 38 is fixed inside the guide plate 34. The drive shaft 38 is slidably connected to the surface of the linkage 36.
[0036] A limiting ring 311 is fixed at the bottom of the guide plate 34. An annular hole 312 adapted to the limiting ring 311 is opened at the bottom of the material cylinder 10. The outer wall of the limiting ring 311 is attached to the inner wall of the annular hole 312. The limiting ring 311 is slidably connected inside the annular hole 312. A plurality of side support plates 313 are fixed on the outer wall of the guide plate 34. The side support plates 313 correspond one-to-one with the connecting piece 21. The bottom of the connecting piece 21 is rotatably connected to the top of the corresponding side support plate 313.
[0037] It should be noted that the surface of the linkage 36 has peaks and valleys. When the drive shaft 38 slides from the valley to the peak of the linkage 36, the guide plate 34 can drive the lifting cylinder 35 to move upward around its axis. At this time, the guide plate 34 compresses the space inside the cylinder 10, thereby accelerating the discharge of gas inside the cylinder 10. Simultaneously, the guide plate 34 drives the connected boss 2101 to move upward through the side support plate 313. At this time, the multiple bosses 2101 on the connector 21 can move closer and close in sequence, thereby improving the crushing degree of the material by the side shaft 24 and the spiral cutter 25.
[0038] The lifting cylinder 35 has a second limiting block 39 fixed inside. The outer wall of the limiting shaft 31 has a second limiting groove 310 that matches the second limiting block 39. The second limiting block 39 is slidably connected inside the second limiting groove 310. The second limiting block 39 cooperates with the second limiting groove 310 to limit the guide plate 34, thereby maintaining the stability of the guide plate 34.
[0039] The material cylinder 10 is equipped with a crushing mechanism 40, which is used to improve the crushing strength of the material by the mixing mechanism 20.
[0040] The crushing mechanism 40 includes a linkage shaft 41 disposed inside the boss 2101, with both ends of the linkage shaft 41 fixed to one side wall of the corresponding side shaft 24, and the side shaft 24 and the linkage shaft 41 being coaxially arranged. A second external toothed ring 42 is installed on the outside of the linkage shaft 41. A lifting shaft 44 is fixed on the inner top wall of the connecting block 2102. A through hole 45 adapted to the lifting shaft 44 is opened on the boss 2101, and the lifting shaft 44 and the through hole 45 are coaxially arranged. The lifting shaft 44 is slidably connected inside the through hole 45. A rack 43 is fixed at the bottom of the lifting shaft 44, and the rack 43 is meshed with the second external toothed ring 42. A return spring 46 is fixed between the top of the boss 2101 and the inner top wall of the connecting block 2102 to support the boss 2101 so as to drive the released boss 2101 to return.
[0041] When using the device, the material is first fed into the inside of the material cylinder 10 through the feed port 11. Then, the control system connected to the drive source 33 turns on the drive source 33. At this time, the output end of the drive source 33 drives the connected limiting shaft 31 to rotate. The limiting shaft 31 drives the guide plate 34 connected to the lifting cylinder 35 to rotate through the second limiting block 39 and the second limiting groove 310. At the same time, the limiting shaft 31 drives the connecting ring 27 to rotate through the side plate 32. The connecting ring 27 drives the connecting piece 21 to slide circumferentially through the fixing plate 28. Since the first external toothed ring 29 is meshed with the toothed ring 210, the top shaft 26 rotates axially, thereby driving the connecting piece 21 to rotate. The side shaft 24 and the spiral blade 25 on the boss 2101 stir the material.
[0042] When the drive shaft 38 slides from the valley of the linkage 36 to its peak, the drive shaft 38 drives the guide plate 34 to move upward, while the limiting ring 311 moves upward inside the annular hole 312. At this time, the guide plate 34 compresses the space inside the material cylinder 10, thereby accelerating the discharge of gas inside the material cylinder 10. The guide plate 34 drives the connected boss 2101 to move upward through the side support plate 313. The boss 2101 at the bottom moves upward inside the corresponding connecting block 2102, and the boss 2101 simultaneously compresses the return spring 46. The first limiting block 22 is inside the first limiting groove 23. The part slides, and at this time, multiple protrusions 2101 approach each other in sequence, which can reduce the gap between multiple protrusions 2101. This allows the side shaft 24 to work with the spiral cutter 25 to stir and crush materials in different areas. When the protrusions 2101 move upward, the second outer toothed ring 42 can drive the linkage shaft 41 to rotate through the meshing connection with the rack 43. The side shaft 24 drives the spiral cutter 25 to rotate, which can cut the material and prevent the material from clumping. When the drive shaft 38 slides from the peak to the valley, multiple protrusions 2101 move away from each other in sequence, and the above operation is completed again. When feeding is required, the control valve of the discharge port 12 can be opened.
[0043] A feeding method for factory-scale eel farming includes the following steps: Step 1: Pour the material into the inside of the material cylinder 10 through the feed inlet 11; Step 2: Turn on the drive source 33. The drive source 33 drives the connecting ring 27 to rotate through the limit shaft 31 and the side plate 32. The first outer toothed ring 29 cooperates with the toothed ring 210 to drive the connecting piece 21 to rotate, so that the side shaft 24 and the spiral cutter 25 can stir and crush the material inside the material cylinder 10. Step 3: The material after mixing and crushing can be discharged through the opened discharge port 12.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
