Description

Technical Field

[0001] This invention relates to the field of premix preparation, and more particularly to a premix preparation apparatus for improving the immunity of aquatic animals. Background Technology

[0002] An existing patent (publication number: CN219701769U) discloses a premix preparation device, including a mixing and crushing cylinder. The outer wall of the mixing and crushing cylinder is rotatably connected to the middle of a support frame on opposite sides. A second support and a first support are fixedly connected to the front and rear ends of the bottom of the support frame, respectively. A second fixed rod and a first fixed rod pass through the upper middle of the left and right sides of the second and first supports, respectively. A crushing and mixing mechanism is provided in the middle of the mixing and crushing cylinder. A cleaning mechanism is engaged on the left side of the first fixed rod. A collection and processing mechanism is provided at the bottom of the adjacent side of the second and first supports. However, this device has a fixed rotation method, which means that "the rotation of the mixing and crushing cylinder will quickly turn over and mix the feed inside." This makes the trajectory of the feed relatively regular when the mixing and crushing cylinder turns over the feed, resulting in a limited contact area between the feed and the crushing blades. The crushing blades at various positions are not fully utilized, affecting the crushing efficiency. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a premixed feed preparation device for aquatic animals. This device features a crushing shaft with a double-layer design of crushing shaft and outer crushing blades. The outer crushing blades, in conjunction with an outer blade clearance groove, perform initial crushing of the outer feed, while the inner crushing blades are arranged more finely to further crush the feed closer to the center. This results in higher overall crushing efficiency and better crushing effect. It not only has a good appetite-stimulating effect, increasing feed intake, improving feed conversion rate, and promoting growth, but also has antibacterial properties, improving the immune status of the animal, and enhancing the vitality of aquatic animals.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A premix preparation device for improving the immunity of aquatic animals includes a main protective shell and a protective cover. The bottom of the main protective shell has a discharge port, and the protective cover is fixedly connected to one side of the main protective shell. The protective cover has a feed filling port on one side. The main protective shell and the protective cover together protect the device and support the internal structure. A crushing mechanism is set inside the main protective shell. The crushing mechanism crushes, turns, and screens the feed placed inside. A power mechanism is located on the side of the crushing mechanism near the inside of the main protective shell. The power mechanism includes a crushing drive device and a swing drive device. The crushing drive device is located in the center, and the swing drive device surrounds the outside of the crushing drive device. The crushing drive device provides power for the crushing movement of the crushing mechanism, and the swing drive device provides power for the turning and screening movement of the crushing mechanism, making the movement state of the crushing mechanism more diverse and the movement trajectory of the feed placed inside the crushing mechanism more complex, thereby enhancing the crushing effect and increasing the crushing efficiency.

[0006] The crushing drive device includes a crushing drive motor, a gear mounting plate, and a main drive gear. A power mechanism protective plate is located on one side of the main protective shell. The gear mounting plate is positioned inside the main protective shell. A drive shaft clearance groove is located in the center of the gear mounting plate. Gear plate connecting columns are evenly arranged around the drive shaft clearance groove on the surface of the gear mounting plate. The ends of the gear plate connecting columns are fixedly connected to the power mechanism protective plate. A motor mounting groove is located in the center of the gear plate connecting column array. A certain distance exists between the motor mounting groove and the gear mounting plate. The crushing drive motor is inserted into and fixed inside the motor mounting groove. The main drive gear is fixedly connected to the center of the transmission shaft of the crushing drive motor. The main drive gear is located in the gap between the motor mounting groove and the gear mounting plate.

[0007] The swing drive device includes a driven gear, a tilting cylinder drive platform, a drive rack, an inner track positioning ring, a driven gear shaft, a drive rod, a rack drive block, and a curved groove connecting column. The gear mounting plate surface has a driven gear shaft connection groove, which is evenly arranged around the outside of the motor mounting groove. The driven gear shaft connection groove is rotatably connected to the driven gear shaft. One end of the driven gear shaft is fixedly connected to the driven gear, which meshes with the main drive gear. The gear mounting plate surface has track limiting curved grooves, which are evenly arranged in an array around the driven gear shaft connection groove. A rack drive block is positioned at the corresponding location of each track limiting curved groove. The rack drive block has a curved groove connecting hole and a rack connection platform in its center, with the curved groove connecting hole being centrally located. The rack and pinion connecting platforms are distributed on both sides of the curved groove connecting hole. A curved groove connecting post is provided between the trajectory limiting curved groove and the rack drive block. The top of the curved groove connecting post has a curved groove connecting post, which is adapted to the curved groove connecting hole and slides inside the curved groove connecting hole. The curved groove connecting post and the rack drive block are connected by a spring. The driven gear surface has an inner drive rod connecting post. One side of the drive rod is rotatably connected to the inner drive rod connecting post, and the other side of the drive rod is rotatably connected to the curved groove connecting post. The curved groove connecting post is adapted to the trajectory limiting curved groove and slides inside the trajectory limiting curved groove. One side of the rack drive block has an inner trajectory positioning block, and the rack drive block array is formed. An inner trajectory positioning ring is centrally located and surrounds the outer side of the drive shaft of the crushing drive motor. The inner trajectory positioning ring has inner trajectory positioning slide rods on its side, which are evenly arranged around the ring. These slide rods are adapted to the inner trajectory positioning block and are connected to it, sliding within the block. A drive rack is located on the outer side of the rack drive block, with a rack connecting slide rod on one side. This slide rod is adapted to the rack connecting platform and is connected to it, sliding within the platform. The drive rack and platform are connected by a spring. A tilting drum drive platform is located on the side of the gear mounting plate furthest from the crushing drive motor. The inside of the tilting cylinder drive platform has a gear plate connecting slide groove, which is adapted to the gear mounting plate and connects to it. The gear plate connecting slide groove slides on the outside of the gear mounting plate. One side of the gear plate connecting slide groove has a driven gear ring, which meshes with the drive rack. The trajectory limiting groove consists of a main moving slide groove, a secondary moving slide groove, a displacement stop, and an anti-displacement stop. The main moving slide groove is a smooth arc. The secondary moving slide groove is located below the main moving slide groove, near the left end of the main moving slide groove. The main moving slide groove has a displacement stop inside, located on the right side of the intersection of the left opening of the secondary moving slide groove and the main moving slide groove. The right side of the displacement stop has a first guide slope. The secondary moving slide groove has an anti-displacement stop inside.The anti-displacement stop is located below the intersection of the right opening of the secondary moving slide and the main moving slide, and the lower part of the anti-displacement stop has a second guide slope.

[0008] Beneficial effects: 1. In this invention, the feed is put into the turning cylinder through the feed filling port. The turning cylinder rotates counterclockwise as a whole during the swinging process. The stirring plate set in the turning cylinder continuously stirs the feed placed inside. Combined with the swinging of the turning cylinder itself, the movement trajectory of the feed inside is more complex and the distribution range is wider. The contact range with the outer and inner crushing blades is larger, thereby making the crushing efficiency of this device higher. At the same time, the crushing shaft adopts a double-layer blade design with a crushing shaft and outer crushing blades. The outer crushing blades, together with the outer blade avoidance groove, perform initial crushing of the feed on the periphery. The inner crushing blades are arranged more finely, and the feed near the center is crushed more finely. The overall crushing efficiency is higher and the crushing effect is better.

[0009] 2. In this invention, the auxiliary moving chute is located near the left side of the main moving chute. When the curved groove connecting column slides into the auxiliary moving chute, it is not accelerated to high speed. When the drive rack and driven gear ring are disconnected, the rotation speed of the turning cylinder drive platform is also low. After the turning cylinder drive platform is disengaged from the drive rack, it will only move a short distance at low speed due to its own inertia. This results in a large difference between the counterclockwise and clockwise strokes when the turning cylinder drive platform drives the turning cylinder to rotate, ensuring the lifting efficiency of the stirring plate when lifting the feed.

[0010] 3. The oscillation process of the rack drive block of the present invention is driven by the driven gear, so that the oscillation speed of the rack drive block changes in a trigonometric function distribution, so that the speed of the rack drive block is zero when it runs to the left limit position and the right limit position, making the rack drive block change direction more smoothly and run more stably.

[0011] 4. In this invention, the drive rack and rack connecting platform are connected by a spring. During the re-alignment process between the drive rack and the driven gear ring, if the drive rack and driven gear ring are not fully aligned when the curved groove connecting column slides out of the secondary moving groove, the spring between the drive rack and the rack connecting platform will be compressed to prevent the curved groove connecting column from getting stuck during the sliding out of the secondary moving groove. After the drive rack and driven gear ring are aligned, the spring relaxes, and the drive rack and driven gear ring are fully aligned. The alignment process is stable, efficient, and runs smoothly, and can also effectively prevent jamming during the alignment process.

[0012] 5. The trajectory limiting curved groove of this invention adopts a double curved groove design with a main moving groove and a secondary moving groove. Displacement blocks and anti-displacement blocks are respectively set at the two intersections of the main moving groove and the secondary moving groove. When the curved groove connecting column slides from right to left in the main moving groove and passes through the right opening of the secondary moving groove, the anti-displacement block limits the curved groove connecting column, preventing it from cutting into the secondary moving groove during leftward sliding. When the curved groove connecting column slides leftward past the displacement block, it is guided by the first guiding inclined surface and lifted, thus smoothly passing the displacement block without being stuck. Conversely, when the curved groove connecting column moves rightward, it is guided by the displacement block to cut into the secondary moving groove, and guided by the second guiding inclined surface to pass through the anti-displacement block without being stuck. This ensures that each reciprocating motion of the curved groove connecting column is accurate and stable. Attached Figure Description

A motor mounting groove 14 is provided in the middle of the array of gear plate connecting columns 13. There is a certain distance between the motor mounting groove 14 and the gear mounting plate 12. The crushing drive motor 11 is inserted into the motor mounting groove 14 and fixedly fixed. The main drive gear 34 is fixedly connected to the middle of the transmission shaft of the crushing drive motor 11. The main drive gear 34 is located in the gap between the motor mounting groove 14 and the gear mounting plate 12.

[0031] Example 3:

[0032] The swing drive device 202 of the present invention includes a driven gear 15, a tilting cylinder drive platform 21, a drive rack 23, an inner track positioning ring 35, a driven gear shaft 38, a drive rod 39, a rack drive block 41, and a curved groove connecting column 48. The surface of the gear mounting plate 12 has a driven gear shaft connecting groove 52, which is evenly arranged around the outside of the motor mounting groove 14. The driven gear shaft connecting groove 52 is rotatably connected to the driven gear shaft 38. One end of the driven gear shaft 38 is fixedly connected to the driven gear 15, which meshes with the main drive gear 34. The surface of the gear mounting plate 12 has a track limiting curved groove 43, which is evenly arranged in an array around the driven gear shaft connecting groove 52. Each track limiting curved groove 43... Each corresponding position is provided with a rack drive block 41. The rack drive block 41 has a curved groove column connecting hole 47 and a rack connecting platform 45 in the middle. The curved groove column connecting hole 47 is in the center position, and the rack connecting platform 45 is distributed on both sides of the curved groove column connecting hole 47. A curved groove connecting column 48 is provided between the trajectory limiting curved groove 43 and the rack drive block 41. The top of the curved groove connecting column 48 has a curved groove column connecting column 42. The curved groove column connecting column 42 is adapted to the curved groove column connecting hole 47 and connects to the curved groove column connecting hole 47. The curved groove column connecting column 42 slides inside the curved groove column connecting hole 47. The curved groove connecting column 48 and the rack drive block 41 are connected by a spring. The driven gear 15 has an inner drive rod connecting column 37 on its surface and a drive rod 39 on one side. The drive rod 39 is rotatably connected to the inner drive rod connecting column 37, and the other side of the drive rod 39 is rotatably connected to the curved groove connecting column 42. The curved groove connecting column 48 is adapted to the trajectory limiting curved groove 43 and is connected to the trajectory limiting curved groove 43. The curved groove connecting column 48 slides inside the trajectory limiting curved groove 43. One side of the rack drive block 41 has an inner trajectory positioning block 44. An inner trajectory positioning ring 35 is set at the center of the rack drive block 41 array group. The inner trajectory positioning ring 35 surrounds the outside of the transmission shaft of the crushing drive motor 11. The side of the inner trajectory positioning ring 35 has an inner trajectory positioning slide rod 36. The inner trajectory positioning slide rod 36 is evenly arranged around the inner trajectory positioning ring 35 and is adapted to the inner trajectory positioning block 44. The inner trajectory positioning slide rod 36 is connected to the inner trajectory positioning block 44. An inner trajectory positioning block 44 is connected to the inner trajectory positioning slide rod 36, which slides inside the inner trajectory positioning block 44. A drive rack 23 is provided on the outer side of the rack drive block 41. A rack connecting slide rod 46 is provided on one side of the drive rack 23. The rack connecting slide rod 46 is adapted to the rack connecting platform 45 and is connected to the rack connecting platform 45. The rack connecting slide rod 46 slides inside the rack connecting platform 45. The drive rack 23 and the rack connecting platform 45 are connected by a spring. A tilting drum drive platform 21 is provided on the side of the gear mounting plate 12 away from the crushing drive motor 11. The tilting drum drive platform 21 has a gear plate connecting groove 55 inside, which is adapted to the gear mounting plate 12 and is connected to the gear mounting plate 12.The gear plate connecting slide 55 slides on the outside of the gear mounting plate 12. A driven gear ring 22 is located on one side of the gear plate connecting slide 55, meshing with the drive rack 23. The trajectory limiting groove 43 consists of a main moving slide 431, a secondary moving slide 432, a displacement stop 433, and an anti-displacement stop 434. The main moving slide 431 is a smooth arc. The secondary moving slide 432 is located below the main moving slide 431, near the left side of the main moving slide 431. At the end, the main moving slide 431 has a displacement stop 433 inside. The displacement stop 433 is located on the right side of the intersection of the left opening of the secondary moving slide 432 and the main moving slide 431. The right side of the displacement stop 433 has a first guide slope 435. The secondary moving slide 432 has an anti-displacement stop 434 inside. The anti-displacement stop 434 is located below the intersection of the right opening of the secondary moving slide 432 and the main moving slide 431. The lower part of the anti-displacement stop 434 has a second guide slope 436.

[0033] Furthermore, the crushing drive motor 11 drives the main drive gear 34 to rotate, which in turn drives the driven gear 15 to rotate. Simultaneously, the driven gear 15 rotates via the drive rod 39, causing the curved groove connecting column 48 to slide left and right within the track-limited curved groove 43, thus causing the rack drive block 41 to swing left and right. When the curved groove connecting column 48 slides from right to left within the main moving slide 431, the curved groove connecting column 48 remains entirely within the main moving slide 431, causing the rack drive block 41 to drive the tilting cylinder drive table 21 to rotate counterclockwise via the drive rack 23. When the curved groove connecting column 48 slides from left to right within the main moving slide 431, the curved groove connecting column... When the connecting column 48 passes through the secondary moving slide 432, it will enter the interior of the secondary moving slide 432. At this time, the drive rack 23 and the driven gear ring 22 will be disconnected until the curved groove connecting column 48 re-enters the main moving slide 431 from the secondary moving slide 432, so that the drive rack 23 and the driven gear ring 22 are reconnected. After that, the curved groove connecting column 48 continues to slide to the right in the main moving slide 431, so that the rack drive block 41 drives the flipping cylinder drive platform 21 to rotate clockwise through the drive rack 23, so that the distance that the drive rack 23 drives the driven gear ring 22 to travel counterclockwise is greater than the distance that the drive rack 23 drives the driven gear ring 22 to travel clockwise.

[0034] It should be noted that the trajectory limiting groove 43 adopts a double-curved groove design with a main moving groove 431 and a secondary moving groove 432. Displacement blocks 433 and anti-displacement blocks 434 are respectively installed at the two intersections of the main moving groove 431 and the secondary moving groove 432. When the groove connecting column 48 slides from right to left through the right opening of the secondary moving groove 432 within the main moving groove 431, the anti-displacement block 434 will limit the movement of the groove connecting column 48, preventing it from moving. The curved groove connecting column 48 will not cut into the interior of the secondary moving groove 432 during the left sliding process. When the curved groove connecting column 48 slides left and passes the displacement stop 433, it is lifted by the first guide slope 435, so that it can pass smoothly through the displacement stop 433 without being stuck. Conversely, when the curved groove connecting column 48 moves right, it is guided by the displacement stop 433 to cut into the interior of the secondary moving groove 432, and is guided by the second guide slope 436 to pass through the anti-displacement stop 434 without being stuck, so that each reciprocating motion of the curved groove connecting column 48 is accurate and stable.

[0035] It should also be noted that the drive rack 23 and the rack connecting platform 45 are connected by a spring. During the re-interaction process between the drive rack 23 and the driven gear ring 22, if the drive rack 23 and the driven gear ring 22 are not fully aligned when the curved groove connecting column 48 slides out of the secondary moving slide groove 432, the spring between the drive rack 23 and the rack connecting platform 45 will be compressed to prevent the curved groove connecting column 48 from getting stuck during the process of sliding out of the secondary moving slide groove 432. After the drive rack 23 and the driven gear ring 22 are aligned, the spring will relax, and the drive rack 23 and the driven gear ring 22 will be fully connected. The connection process is stable and efficient, and can also effectively avoid getting stuck during the connection process.

[0036] Example 4:

[0037] The crushing mechanism 3 of the present invention includes a tilting drum positioning roller 18, a tilting drum 24, and a crushing shaft 31. The tilting drum 24 is fixedly connected to one side of the tilting drum drive platform 21. The surface of the tilting drum 24 has a screening screen 25, which is evenly arranged around the tilting drum 24. Inside the tilting drum 24 are stirring plates 28, with three sets of stirring plates 28 evenly arranged around the tilting drum 24. The inner side of each stirring plate 28 has an outer cutter clearance groove 29. The middle of the tilting drum drive platform 21 has a crushing shaft connecting groove 54, and the crushing shaft 31 is rotatably connected to the crushing shaft connecting groove 54. The drive shaft of the motor 11 is fixedly connected to the crushing shaft 31. The side of the crushing shaft 31 has an outer crushing cutter 32 and an inner crushing cutter 33. The outer crushing cutter 32 and the inner crushing cutter 33 are arranged evenly and alternately around the crushing shaft 31. The number and position of the outer crushing cutter 32 and the outer cutter clearance groove 29 correspond. The main protective shell 1 has a positioning roller connecting platform 17 inside. The positioning roller connecting platform 17 is evenly arranged around the turning cylinder 24. The positioning roller connecting platform 17 is rotatably connected to the turning cylinder positioning roller 18. The turning cylinder positioning roller 18 is pressed against the side of the turning cylinder 24.

[0038] Furthermore, the feed falls into the inside of the turning drum 24 through the feed filling port 27. The crushing drive motor 11 drives the crushing shaft 31 to rotate. While the crushing shaft 31 rotates, the outer crushing blade 32 and the inner crushing blade 33 cut and crush the feed. Simultaneously, the turning drum drive table 21 drives the turning drum 24 to continuously swing and rotate counterclockwise. The qualified crushed feed will fall into the discharge port 19 through the screening screen 25 during the swinging process and be recycled. The uncrushed feed at the bottom is lifted by the stirring plate 28 and poured onto the crushing shaft 31 to be crushed again when it is lifted to a certain height, until all the feed is crushed and the processing is completed.

[0039] It should be noted that the oscillation process of the rack drive block 41 is driven by the driven gear 15, which makes the oscillation speed of the rack drive block 41 change in a trigonometric function distribution, so that the speed of the rack drive block 41 is zero when it runs to the left limit position and the right limit position, making the change of direction of the rack drive block 41 smoother and not generating excessive vibration.

[0040] It should also be noted that the auxiliary moving chute 432 is close to the left side of the main moving chute 431. When the curved groove connecting column 48 slides into the auxiliary moving chute 432, it is not accelerated to high speed. When the drive rack 23 is disconnected from the driven gear ring 22, the rotation speed of the turning cylinder drive platform 21 is also low. After the turning cylinder drive platform 21 is disengaged from the drive rack 23, it will only move a short distance at low speed due to its own inertia. When the turning cylinder drive platform 21 drives the turning cylinder 24 to rotate, the difference between the counterclockwise stroke and the clockwise stroke is large, which ensures the lifting efficiency of the stirring plate 28 when lifting the feed.

[0041] It should also be noted that the feed is fed into the turning cylinder 24 through the feed filling port 27. The turning cylinder 24 rotates counter-clockwise throughout its oscillation process. The stirring plates 28 on the turning cylinder 24 continuously agitate the feed inside. Combined with the oscillation of the turning cylinder 24 itself, this makes the feed's trajectory more complex and its distribution wider, increasing the contact area with the outer crushing blades 32 and inner crushing blades 33. This results in higher crushing efficiency, allowing for rapid crushing even with excessive feed, good crushing effect, and preventing blockages that could cause machine overheating. Simultaneously, the crushing shaft 31 employs a double-layer blade design with the outer crushing blades 32, effectively crushing feed premixes with high moisture and viscosity, preventing screen blockage. The outer crushing blades 32, in conjunction with the outer blade clearance groove 29, perform initial crushing of the outer feed, while the inner crushing blades 33 are more densely arranged, providing finer crushing of the feed near the center, preventing blockages due to excessive moisture content in the premix. Overall, the crushing efficiency is higher, and the crushing effect is better. The feed, which includes quercetin, atractylodes polysaccharide, baicalin, and vitamin C, is added qualitatively and quantitatively. This not only has a good appetite-stimulating effect, increases feed intake, improves feed conversion rate, and promotes growth, but also has antibacterial effects, improves the body's immune status, enhances the vitality of aquatic animals, and can significantly increase the economic benefits of aquaculture.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
