A feed mixing device for marine aquaculture that facilitates feed discharge.

Abstract

This invention discloses a feed mixing device for marine aquaculture that facilitates feed discharge. This invention relates to the field of mixing equipment technology. When discharging feed after mixing, a scraper is typically used to scrape the feed adhering to the inner wall, causing it to fall out under its own weight. However, when feed gets stuck between the scraper and the barrel wall, a gap is created, preventing complete removal of the adhering material. This invention addresses this issue by using a scraper and raised strips. While the scraper scrapes the inner wall of the mixing barrel, the inclined surface of the raised strips blocks the scraped feed during discharge, causing it to accumulate and fall out under its own weight. Simultaneously, during scraping, the grooves on the scraper allow any stuck feed to enter the grooves during rotation, preventing gaps between the scraper and the barrel wall that would prevent the feed from being scraped out.

Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, specifically to a feed mixing device for marine aquaculture that facilitates material discharge. Background Technology

[0002] Marine aquaculture refers to the production method of obtaining aquatic products by creating suitable environmental conditions in the ocean through artificial means to promote the mass reproduction and rapid growth of farmed organisms. It can be divided into tidal flat aquaculture, shallow sea aquaculture, harbor aquaculture, deep-sea aquaculture, marine ranching, and factory farming. Marine aquaculture feed mixing equipment is used to mix and stir various feed raw materials required for marine aquaculture to make them into a uniform feed product. It can improve feed quality and aquaculture efficiency. It usually has a vertical mixing drum with a mixing shaft and mixing blades inside. The material is added from the top and moves along the axial and radial directions under the action of the mixing blades to achieve mixing.

[0003] When discharging after mixing, a scraper is usually used to scrape the feed adhering to the inner wall, so that the feed adhering to the inner wall is scraped out and falls out under its own weight. However, when feed gets stuck between the scraper and the barrel wall, a gap will be created between the scraper and the barrel wall, so that the material adhering to the barrel wall cannot be completely scraped off. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A feed mixing device for marine aquaculture that facilitates feed discharge includes:

[0006] A mixing tank, wherein a feed chute is fixedly installed on the top of the mixing tank and a discharge chute is installed on the bottom of the outer side of the mixing tank. A motor is fixedly installed at the center of the top of the mixing tank. The output end of the motor passes through the mixing tank and extends into its interior. A drive shaft is fixedly installed on the output end of the motor through a coupling.

[0007] An internal stirring mechanism is installed inside the mixing tank, and the internal stirring mechanism is fixedly installed on the outside of the drive shaft;

[0008] A water guiding mechanism is installed inside the mixing tank and is located directly above the internal stirring mechanism.

[0009] A rotating ring is rotatably mounted on the top of the inner wall of the mixing tank. A connecting plate is fixedly mounted on the inner wall of the rotating ring. The top of the connecting plate has evenly spaced slots, and its inner wall is fixedly connected to the top of the outer side of the drive shaft. The top of the rotating ring has an annular groove, and a top guide ring is rotatably mounted at this groove. The top of the top guide ring is an inwardly sloping surface. A scraper is fixedly mounted on the bottom of the rotating ring. The scrapers are evenly spaced along the center of the rotating ring, and each scraper has a scraping blade on both sides. The non-opposing surfaces of the scrapers are in contact with the inner wall of the mixing tank, and each non-opposing surface of the scraper has a groove. The scraper, in conjunction with the raised strips, scrapes... When the inner wall of the mixing tank is rotated, the inclined surface of the convex strips is used to block the scraped feed during discharge, causing the feed to accumulate and fall out under its own weight. At the same time, during the scraping process, the grooves of the scraper are used to prevent the scraper from getting stuck between the scraper and the tank wall. As the scraper rotates, the scraper enters the grooves, preventing gaps from forming between the tank wall and the scraper, which would prevent the feed adhering to the tank wall from being scraped out. A base is rotatably installed at the bottom of the inner wall of the mixing tank. The inner wall of the base is fixedly connected to the bottom end of the drive shaft. The center position of the opposite side of the scraper is fixedly installed with convex strips. The side of the convex strip away from the scraper is an inclined surface that slopes from top to bottom towards the scraper side.

[0010] Preferably, a convex ring is provided at the center of the top of the chassis, and an inclined strip is fixedly installed on the outer side of the convex ring. The inclined strip is evenly installed along the center of the chassis. Through the cooperation between the chassis and the inclined strip, during rotation, the inclined strip and the chassis rotate together. When the mixing rotates in the forward direction, the inclined strip drives the bottom feed closer to the center, assisting the internal mixing mechanism in mixing the feed. When the discharge rotates in the reverse direction, the inclined strip drives the bottom feed to move outward during rotation, allowing the feed to be smoothly discharged from the discharge trough. The bottom of the inclined strip is in close contact with the top of the chassis. An inner baffle is fixedly installed on the top of the inner wall of the discharge trough. The bottom end of the inner baffle is inclined away from the mixing tank. A plate groove is opened on the top of the discharge trough, and a sealing plate is slidably installed at the plate groove of the discharge trough.

[0011] Preferably, the internal stirring mechanism includes a shaft cylinder, the inner wall of which is fixedly connected to the outer side of the drive shaft, and symmetrically arranged protruding rings on the outer side of the shaft cylinder. Support plates are fixedly installed at each of the protruding rings, and extension plates are evenly arranged on the outer side of each support plate. A rotating column is installed between the support plates, and both ends of the rotating column are rotatably connected to the inner walls of the extension plates. Clamping plates are fixedly installed at both ends of the outer side of the rotating column, and stirring blades are fixedly installed between the clamping plates. Through the cooperation of the rotating column and the stirring blades, during the stirring process, the rotating column rotates along the center position of the drive shaft axis while utilizing the resistance of the viscous feed to the stirring blades, causing the rotating column to rotate on its own axis. This reduces the resistance encountered during the process and avoids the initial stirring resistance being too high, which could obstruct the stirring and prevent it from proceeding. The stirring blades are evenly installed along the center position of the clamping plates.

[0012] Preferably, a conical block is fixedly installed at the bottom of the outer side of the drive shaft. The outer diameter of the conical block gradually decreases from top to bottom, and the bottom of the conical block is fixedly connected to the top of the chassis. A fixed disk is fixedly installed at the top of the conical block, and a spiral plate is fixedly installed at the top of the fixed disk. The spiral plate is evenly installed along the center position of the fixed disk. Through the cooperation of the spiral plate and the inclined bar, during stirring, the inclined bar drives the bottom feed close to the spiral plate. At the same time, the spiral plate drives the bottom feed upward, ensuring the exchange of materials between the upper and lower layers, improving the stirring effect, and avoiding uneven stirring between the upper and lower layers. The spiral plate is located directly below the support disk.

[0013] Preferably, the water guiding mechanism includes a water collection tank whose top is fixedly connected to the top of the inner wall of the mixing tank, and a water guiding pipe is fixedly installed on the top of the water collection tank. The end of the water guiding pipe away from the water collection tank passes through the mixing tank and extends to its top. A spray pipe is fixedly installed at the bottom of the water collection tank. The spray pipe is evenly installed along the center of the water collection tank and is located at the edge of the bottom of the water collection tank.

[0014] Preferably, a conical disc is fixedly installed on the inner wall of the water collection tank, and grid grooves are evenly opened on the outer side of the conical disc. The spray pipe and the water guide pipe are located on both sides of the conical disc. A filter screen is fixedly installed on the outer side of the conical disc, and an inner baffle ring is fixedly installed on the inner wall of the conical disc. Through the cooperation of the inner baffle ring and the conical disc, while the filter screen and the conical disc cooperate to block foreign objects, the impact of the water flow causes the filtered material to be flushed into the bottom of the inner baffle ring for centralized collection. At the same time, the inner baffle ring blocks the water flow from impacting the foreign objects collected at the bottom of the inner baffle ring, so that the foreign objects are smoothly collected at the bottom of the inner baffle ring. There is a gap between the bottom of the inner baffle ring and the bottom of the inner wall of the water collection tank.

[0015] This invention provides a feed mixing device for marine aquaculture that facilitates feed discharge. It has the following beneficial effects:

[0016] I. This feed mixing equipment for marine aquaculture, which facilitates feed discharge, utilizes a scraper and convex strips. When the scraper scrapes the inner wall of the mixing tank, the inclined surface of the convex strips blocks the scraped feed during discharge, causing it to accumulate and fall out under its own weight. Simultaneously, during the scraping process, the grooves on the scraper prevent feed from getting stuck between the scraper and the tank wall. As the scraper rotates, the feed enters the grooves, preventing gaps from forming between the tank wall and the scraper, which would otherwise prevent the feed adhering to the tank wall from being scraped out.

[0017] II. This feed mixing equipment for marine aquaculture, which facilitates feed discharge, utilizes the cooperation between the chassis and the inclined bars. During rotation, the inclined bars, installed at an angle, move the feed at the bottom towards the center, assisting the internal mixing mechanism in mixing the feed. During reverse discharge, the inclined bars move the feed at the bottom outwards during rotation, allowing the feed to be smoothly discharged from the discharge trough.

[0018] Third, this feed mixing equipment for marine aquaculture, which facilitates feed discharge, uses a rotating column and a stirring blade to rotate the column along the center of the drive shaft during the mixing process. At the same time, the resistance of the viscous feed on the stirring blade causes the rotating column to rotate, reducing the resistance encountered during the process and avoiding the inability to mix due to high mixing resistance at the beginning.

[0019] IV. This marine aquaculture feed mixing equipment, which facilitates feed discharge, uses a spiral plate and inclined bars in combination. During mixing, the inclined bars bring the bottom feed closer to the spiral plate, while the spiral plate moves the bottom feed upwards, ensuring the exchange of materials between the upper and lower layers, improving the mixing effect, and avoiding uneven mixing between the upper and lower layers.

[0020] 5. This feed mixing device for marine aquaculture, which facilitates material discharge, uses an inner baffle ring in conjunction with a conical disc. While the filter screen and conical disc work together to block foreign objects, the impact of the water flow causes the filtered material to be flushed into the bottom of the inner baffle ring for centralized collection. At the same time, the inner baffle ring prevents the water flow from impacting the foreign objects collected at the bottom of the inner baffle ring, allowing the foreign objects to be collected smoothly at the bottom of the inner baffle ring.

[0031] 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.

[0032] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0033] A feed mixing device for marine aquaculture that facilitates feed discharge includes:

[0034] A mixing tank 1 is provided with a feed chute 5 fixedly installed on its top and a discharge chute 6 installed on the bottom of the outer side of the mixing tank 1. A motor 4 is fixedly installed at the center of the top of the mixing tank 1. The output end of the motor 4 passes through the mixing tank 1 and extends into its interior. A drive shaft 7 is fixedly installed at the output end of the motor 4 through a coupling.

[0035] The internal stirring mechanism 2 is installed inside the mixing tank 1, and the external side of the drive shaft 7 is fixedly installed on the internal stirring mechanism 2.

[0036] Water guiding mechanism 3 is installed inside the mixing tank 1 and is located directly above the inner stirring mechanism 2;

[0037] A rotating ring 12 is rotatably mounted on the top of the inner wall of the mixing tank 1. A connecting plate 11 is fixedly mounted on the inner wall of the rotating ring 12. The top of the connecting plate 11 has evenly spaced slots, and the inner wall of the connecting plate 11 is fixedly connected to the top of the outer side of the drive shaft 7. The top of the rotating ring 12 has an annular groove, and a top guide ring 13 is rotatably mounted at the annular groove of the rotating ring 12. The top of the top guide ring 13 is an inwardly sloping surface from top to bottom. A scraper 9 is fixedly mounted on the bottom of the rotating ring 12. The scraper 9 is evenly spaced along the center of the rotating ring 12, and scraping blades are provided on both sides of the scraper 9. The non-opposing surfaces of the scraper 9 are in contact with the inner wall of the mixing tank 1, and grooves are provided on the non-opposing surfaces of the scraper 9. During mixing, the fixed connection between the connecting plate 11 and the drive shaft 7 causes the drive shaft 7 to rotate, which in turn drives the rotating ring 12 in the mixing tank 1. The inner wall rotates, and during the rotation, the scraper 9 rotates along the inner wall of the mixing tank 1. The scraper blade of the scraper 9 scrapes the inner wall of the mixing tank 1 during rotation, causing the feed adhering to the inner wall of the mixing tank 1 to be scraped and moved. At the same time, during the rotation and scraping, the scraped feed accumulates at the scraper blade and is squeezed by the subsequent scraped feed to approach the protrusion 16. The protrusion 16 blocks the accumulated feed and squeezes it during the scraping process, gradually moving it closer to the center for mixing. A base plate 10 is rotatably installed at the bottom of the inner wall of the mixing tank 1. The inner wall of the base plate 10 is fixedly connected to the bottom end of the drive shaft 7. Protrusions 16 are fixedly installed at the center of the opposite side of the scraper 9. The side of the protrusion 16 away from the scraper 9 is an inclined surface that slopes from top to bottom towards the scraper 9.

[0038] A raised ring is provided at the center of the top of the chassis 10, and a diagonal strip 15 is fixedly installed on the outer side of the raised ring. The diagonal strip 15 is evenly installed along the center of the chassis 10, and the bottom of the diagonal strip 15 is tightly fitted to the top of the chassis 10. An inner baffle 8 is fixedly installed on the top of the inner wall of the discharge chute 6. During discharge, the inclined surface of the raised strip 16 is used to reduce the contact area between the bottom feed and the raised strip 16, so that the scraped feed falls smoothly to the top of the chassis 10 under its own weight. At the same time, during rotation, the diagonal strips evenly installed on the top of the chassis 10 pass through the feed. 15. During mixing, the inclined bar 15 drives the bottom feed in the mixing tank 1 to move, so that the bottom material is smoothly stirred. During discharge, the base plate 10 cooperates with the inclined bar 15 to make the base plate 10 drive the bottom material to rotate. At the same time, the inclined bar 15 cooperates with the rotation of the base plate 10 to make the inclined bar 15 drive the bottom material to move from the outside to the inside during mixing and from the inside to the outside during discharge. The bottom end of the inner baffle 8 is inclined away from the mixing tank 1. The top of the discharge chute 6 is provided with a plate groove, and a sealing plate 14 is slidably installed at the plate groove of the discharge chute 6.

[0039] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7 As shown, the internal stirring mechanism 2 includes a shaft cylinder 21. The inner wall of the shaft cylinder 21 is fixedly connected to the outer side of the transmission shaft 7, and symmetrically arranged protruding rings are provided on the outer side of the shaft cylinder 21. Support plates 23 are fixedly installed at the protruding rings of the shaft cylinder 21, and extension plates are evenly arranged on the outer side of the support plates 23. In the internal stirring mechanism 2, when the transmission shaft 7 rotates, it drives the shaft cylinder 21 to rotate, causing the shaft cylinder 21 to drive the rotating column 22 to rotate along the axis center of the transmission shaft 7 through the support plates 23. At the same time, during the rotation, the rotating column 22 drives the stirring blade 24 to stir the feed, and simultaneously utilizes... The rotating column 22 is rotatably connected to the support plate 23. During the rotation, the rotating column 22 rotates along the center position of the drive shaft 7 axis. At the same time, the resistance of the viscous feed on the stirring blade 24 is used to make the rotating column 22 rotate, reducing the resistance when the drive shaft 7 rotates. The rotating column 22 is installed between the support plates 23. The two ends of the rotating column 22 are rotatably connected to the inner wall of the extension plate. The two ends of the outer side of the rotating column 22 are fixedly installed with clamping plates 28. The stirring blade 24 is fixedly installed between the clamping plates 28. The stirring blade 24 is evenly installed along the center position of the clamping plates 28.

[0040] A conical block 26 is fixedly installed on the bottom of the outer side of the drive shaft 7. The outer diameter of the conical block 26 gradually decreases from top to bottom, and the bottom of the conical block 26 is fixedly connected to the top of the chassis 10. A fixed disk 27 is fixedly installed on the top of the conical block 26, and a spiral plate 25 is fixedly installed on the top of the fixed disk 27. During stirring, the drive shaft 7 drives the fixed disk 27 to rotate through the conical block 26, causing the fixed disk 27 to drive the spiral plate 25 at the top to move. Utilizing the spiral shape of the spiral plate 25, the material at the bottom layer moves upward during stirring. During discharge, the spiral plate 25 moves downward with the reverse rotation of the motor 4 to assist in discharge. The spiral plate 25 is evenly installed along the center position of the fixed disk 27, and the spiral plate 25 is located directly below the support disk 23.

[0041] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9 As shown, the water guiding mechanism 3 includes a water collection tank 32 whose top is fixedly connected to the top of the inner wall of the mixing tank 1, and a water guiding pipe 31 is fixedly installed on the top of the water collection tank 32. The end of the water guiding pipe 31 away from the water collection tank 32 passes through the mixing tank 1 and extends to its top. In the water guiding mechanism 3, the water guiding pipe 31 is connected to a water pipe, so that water is introduced into the interior of the water collection tank 32 through the water guiding pipe 31. After the water is introduced into the interior of the water collection tank 32, the water first enters the side of the conical disc 34 away from the spray pipe 33. With the cooperation of the conical disc 34 and the filter screen 36, the water passes through the grid groove of the conical disc 34 and is filtered by the filter screen 36 to block foreign objects in the water. After filtration, the water is discharged by the spray pipe 33 and mixed with the feed. The bottom of the water collection tank 32 is fixedly installed with the spray pipe 33. The spray pipe 33 is evenly installed along the center position of the water collection tank 32 and is located at the edge of the bottom of the water collection tank 32.

[0042] A conical disc 34 is fixedly installed on the inner wall of the water collection chamber 32. The outer side of the conical disc 34 is evenly provided with grid grooves. The spray pipe 33 and the water guide pipe 31 are located on both sides of the conical disc 34. A filter screen 36 is fixedly installed on the outer side of the conical disc 34. Foreign objects that are blocked are driven by the impact of the subsequent water flow, causing them to be flushed into the bottom of the inner baffle ring 35 and collected at the bottom of the inner baffle ring 35. The inner baffle ring 35 is fixedly installed on the inner wall of the conical disc 34, and there is a gap between the bottom of the inner baffle ring 35 and the bottom of the inner wall of the water collection chamber 32.

[0043] In use, the worker connects the water pipe to the water guiding mechanism 3, so that the water is introduced into the mixing tank 1 through the water guiding mechanism 3. The feed to be mixed is then poured into the mixing tank 1 through the feed trough 5. Then the motor 4 is started, so that the motor 4 drives the transmission shaft 7 to rotate inside the mixing tank 1, and drives the internal stirring mechanism 2 to move, stirring the feed and water introduced into the tank, so that the water and feed are mixed and the feed is mixed, thus completing the mixing and processing of the feed.

[0044] During mixing, the fixed connection between the connecting plate 11 and the drive shaft 7 causes the drive shaft 7 to rotate. This rotation, via the connecting plate 11, drives the rotating ring 12 to rotate along the inner wall of the mixing tank 1. Simultaneously, the rotation of the ring causes the scraper 9 to rotate along the inner wall of the mixing tank 1. The scraper blades of the scraper 9 scrape the inner wall of the mixing tank 1 during rotation, causing the feed adhering to the inner wall to be moved. Simultaneously, during the scraping process, the scraped feed accumulates at the scraper blades and, under the pressure of subsequent scraping, approaches the protruding strip 16. The protruding strip 16 then blocks the accumulated feed, gradually pushing it towards the center during the scraping process. The feed is placed close together for mixing and stirring. At the same time, during discharge, the inclined surface of the convex strip 16 is used to reduce the contact area between the bottom feed and the convex strip 16, so that the scraped feed falls smoothly to the top of the chassis 10 under its own weight. At the same time, during rotation, the inclined strips 15 evenly installed on the top of the chassis 10 drive the bottom feed in the mixing tank 1 to move during stirring, so that the bottom material is smoothly stirred. During discharge, the chassis 10 and the inclined strips 15 cooperate to make the chassis 10 drive the bottom material to rotate. At the same time, the inclined strips 15 cooperate with the rotation of the chassis 10 to make the inclined strips 15 drive the bottom material to move from the outside to the inside during stirring and from the inside to the outside during discharge.

[0045] In the internal stirring mechanism 2, the drive shaft 7 rotates, driving the shaft cylinder 21 to rotate. The shaft cylinder 21, through the support plate 23, drives the rotating column 22 to rotate along the center of the axis of the drive shaft 7. Simultaneously, during the rotation, the rotating column 22 drives the stirring blade 24 to stir the feed. The rotating connection between the rotating column 22 and the support plate 23 allows the rotating column 22 to rotate along the center of the axis of the drive shaft 7. The resistance of the viscous feed to the stirring blade 24 causes the rotating column 22 to rotate, reducing the resistance during the rotation of the drive shaft 7. Simultaneously, during stirring, the drive shaft 7 drives the fixed plate 27 to rotate through the conical block 26. The fixed plate 27 then drives the top spiral plate 25 to move. The spiral shape of the spiral plate 25 causes the material at the bottom to move upwards during stirring. During discharge, the spiral plate 25 moves the material downwards with the reverse rotation of the motor 4, assisting in discharge.

[0046] In the water guiding mechanism 3, water is connected to the water pipe through the water guiding pipe 31, allowing water to be introduced into the water collection tank 32 through the water guiding pipe 31. After the water is introduced into the water collection tank 32, the water first enters the side of the conical disc 34 away from the spray pipe 33. With the cooperation of the conical disc 34 and the filter screen 36, the water passes through the grid groove of the conical disc 34 and is filtered by the filter screen 36, blocking foreign objects in the water. After filtration, the water is discharged from the spray pipe 33 and mixed with the feed. The blocked foreign objects are driven by the impact of the subsequent water flow, causing the foreign objects to be flushed into the bottom of the inner baffle ring 35, where they are collected.
