Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a feeding device for aquaculture. Background Technology

[0002] With the rapid development of society and the gradual increase in people's consumption levels, the demand for aquatic products has also increased. Ordinary fishing can no longer meet the demand, leading to the development of artificial aquaculture. Traditional artificial aquaculture relies on manual feeding, which is labor-intensive, results in uneven feeding, serious feed waste, and difficulty in accurately controlling the amount of feed, easily causing water pollution. Mechanized aquaculture feeding mechanisms have been developed. Common ones include timed feeders that use motor-driven screw conveyors or vibratory feeders to achieve timed and quantitative feeding, but they cannot be adjusted according to the needs of the farmed species. Pneumatic feeders use fans to blow feed to the aquaculture area, which is suitable for large water surfaces, but the feeding uniformity is poor. All of these methods result in feed not being consumed by the farmed species and remaining in the water for a long time, causing water pollution in the aquaculture area. At the same time, the feeding uniformity is also poor. Therefore, we propose a feeding device for aquaculture. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6To achieve convenient operation, environmental regulation, improved cultivation efficiency, and time saving, this application provides a feeding device for aquaculture. The feeding device includes a base 4, a feeding mechanism 80 at the top of the base 4, a spreading mechanism 90 at the outlet of the feeding mechanism 80, a collecting net 30 on the left side of the base 4, and a first winding mechanism 9 and a second winding mechanism 10 at the left and right ends of the collecting net 30, respectively. The first winding mechanism 9 and the second winding mechanism 10 allow the collecting net 30 to move vertically. The spreading mechanism 90 is positioned... The material spreading mechanism 90, located directly above the center of the collecting net 30, includes a sixth motor 61, a bracket 62, a fourth rotating shaft 63, a housing 65, and a turbine fan 66. The bracket 62 is fixedly connected to the top of the housing 65, and the sixth motor 61 is mounted on the top of the bracket 62. The output shaft of the sixth motor 61 passes through the top of the housing 65 and is fixedly connected to the fourth rotating shaft 63. One end of the fourth rotating shaft 63 is fixedly connected to the turbine fan 66, which is located below the discharge port. A telescopic mechanism 7 is provided directly above the collecting net 30, which allows the collecting net 30 to be expanded or retracted.

[0027] Based on the above, the first winding mechanism 9 and the second winding mechanism 10, which are fixedly connected to the left and right ends of the collection net 30, control the lifting and lowering of the collection net 30. At the same time, the feeding mechanism 90 above the collection net 30 uses the airflow of the turbo fan to scatter feed. The telescopic mechanism 7 realizes the unfolding or retraction of the collection net 30 through telescopic linkage.

[0028] Furthermore, the first winding mechanism 9, the second winding mechanism 10, and the telescopic mechanism 7 work together to form a closed loop for feed feeding and waste feed recycling, reducing water pollution from uneaten feed residue. The use of a turbine fan for spreading feed can improve the uniformity of feed spreading.

[0029] Please see Figures 1 to 2 The first winding mechanism 9 includes a second rotating shaft 33, a third gear 34, and a second motor 35. A first cantilever is provided on the top right side of the fixed plate 8, and a second rotating shaft 33 is rotatably connected to the cantilever. A second rotating wheel 31 is fixedly connected to both ends of the second rotating shaft 33, and a first rope 32 is fixedly connected to the surface of the second rotating wheel 31. The outer surface of the first rope 32 is slidably connected to the first rotating wheel 18, and one end of the first rope 32 passes around the first rotating wheel 18 and is fixedly connected to the left end of the collecting net 30. A third gear 34 is fixedly connected to the middle position of the second rotating shaft 33. A second motor 35 is provided on one side of the third gear 34, and a first worm is fixedly connected to the output end of the second motor 35. The third gear 34 is meshed with the first worm.

[0030] Based on the above, the first worm is rotated by the second motor 35, and the first worm is driven by the gear to drive the second rotating shaft 33 to drive the second rotating wheel 31 to wind the first rope 32, thereby realizing the lifting and lowering control of the left side of the collection net 30.

[0031] Furthermore, the first worm gear and gear transmission has self-locking properties, which can accurately position the lifting height of the collection net 30, preventing it from sliding down due to gravity and improving system stability.

[0032] Please see Figures 1 to 6 The second winding mechanism 10 includes a third rotating shaft 41, a fourth gear 42, and a third motor 43. The third motor 43 is fixedly connected to the top of the base 4 and is located on the right side of the fixing plate 8 and below the second rotating shaft 33. A second worm is fixedly connected to the output end of the third motor 43. The fourth gear 42 meshes with the second worm and is located above the second worm. The third rotating shaft 41 is fixedly connected to the center of the fourth gear 42, and a third wheel 44 is fixedly connected to both ends of the third rotating shaft 41. A second rope 45 is fixedly connected to the surface of the third wheel 44, and a fourth wheel 46 is slidably connected to the outer surface of the second rope 45. A second cantilever 48 is fixedly connected to the top left end of the base 4, and the left end of the second cantilever 48 is rotatably connected to the fourth wheel 46. One end of the second rope 45 passes around the fourth wheel 46 and is fixedly connected to the right end of the collecting net 30.

[0033] Based on the above, the third motor 43 drives the second worm to rotate, and through the meshing transmission of the second worm and the gear, the third rotating shaft 41 drives the third rotating wheel 44 to wind the second rope 45, thereby realizing the lifting and lowering control of the right side of the collection net 30. The second winding mechanism 10 and the first winding mechanism 9 work together to control the overall lifting and lowering of the collection net, ensuring that the collection net moves horizontally up and down.

[0034] Furthermore, the second motor 35 and the third motor 43 form a dual-motor independent drive for the ropes on both sides, which can synchronously adjust the balance of the collection net and prevent uneaten feed from leaking out due to unilateral tilting.

[0035] Please see Figures 1 to 6A fixing plate 8 is installed on the top left side of the base 4. A telescopic mechanism 7 is provided on the left side of the fixing plate 8. The telescopic mechanism 7 includes a first rotating shaft 11, fixing corner blocks 12, steel pipe 14, telescopic arm 15, belt winding 16, fixing rod 17, and a first rotating wheel 18. The fixing corner blocks 12 arranged in an array are fixedly connected to the left side of the fixing plate 8. A steel pipe 14 is installed below the left side of the fixing corner blocks 12. The first rotating shaft 11 is installed above the steel pipe 14. The first rotating shaft 11 and the fixing corner blocks 12 are connected in a certain direction. The top is rotatably connected, and telescopic arms 15 are installed at both ends of the steel pipe 14. A fixed rod 17 is installed at the left end of the telescopic arm 15 and is slidably connected to the fixed rod 17. A first rotating wheel 18 is rotatably connected to both ends of the fixed rod 17. A winding belt 16 is provided between the fixed rod 17 and the first rotating shaft 11, and both ends of the winding belt 16 are fixedly connected to the outer surfaces of the fixed rod 17 and the first rotating shaft 11, respectively. A collection net 30 is provided below the telescopic arm 15, and a first motor is installed at the end of the first rotating shaft 11.

[0036] Based on the above, the telescopic arm includes a first arm, a second arm, a hinge, and a spring. The right side of the first arm is hinged to the left side of the steel pipe 14, and a spring is placed inside the first arm. One end of the spring is fixedly connected to the right end of the first arm. The left end of the first arm is inserted into one end of the hinge, and the spring passes through the left end of the first arm and is snapped into the other end of the hinge. The right end of the second arm is inserted into the other end of the hinge, and its left end is slidably connected to the fixed rod 17. Due to the tension of the internal spring, the telescopic arm itself is in an extended state. The first motor drives the first rotating shaft 11 to rotate, so that the first rotating shaft 11 unwinds the belt 16. The fixed rod expands outward through the telescopic arm, pushing the collection net to unfold. When the first rotating shaft 11 rewinds the belt 16, it drives the fixed rod 17 at the other end of the belt 16 to move closer to the first rotating shaft 11, so that the telescopic arm bends at the hinge, thereby causing the collection net to retract.

[0037] Furthermore, the folded-up state can concentrate uneaten feed residue for easy cleaning, while the unfolded state expands the collection range and improves the recycling efficiency of uneaten feed residue.

[0038] Please see Figure 2 The feeding mechanism 80 includes a material cylinder 1 and a fixed frame 2. The top of the base 4 is fixedly connected to the bottom of the fixed frame 2, and the lower left side of the fixed frame 2 is fixedly connected to the right side of the fixed plate 8. The material cylinder 1 is installed on the top of the fixed frame 2, and the bottom of the material cylinder 1 is funnel-shaped. A fourth motor 51 is provided at the top axial position of the material cylinder 1. The output end of the fourth motor 51 passes through the top of the material cylinder 1 and extends into the interior of the material cylinder 1, where an output shaft 52 is fixedly connected. A cylindrical stirring rod is fixedly connected to the outer surface of the output shaft 52.

[0039] Based on the above, the fourth motor 51 drives the output shaft 52 to rotate, thereby driving the stirring rod to rotate, stirring the feed in the feed drum, preventing clumping and promoting uniform feeding;

[0040] Furthermore, the mixing function prevents feed from piling up and clogging, ensuring smooth subsequent conveying processes and improving feeding stability.

[0041] Please see Figures 1 to 5 The bottom of the material cylinder 1 is fixedly connected to a first guide pipe 57, which is coaxial with the material cylinder 1. The first guide pipe 57 is rotatably connected to a first spiral conveying rod 53, and the top of the first spiral conveying rod 53 is fixedly connected to the output shaft 52.

[0042] Based on the above, the first spiral conveyor rod 53 pushes the feed in the cylinder downward by rotating, and feeds it downward through the first guide pipe 57, realizing vertical conveying by using the spiral transmission principle.

[0043] Furthermore, the first spiral conveyor rod 53 enables quantitative and continuous feeding, avoiding feed accumulation and improving conveying efficiency.

[0044] Please see Figures 1 to 6 The feeding mechanism further includes a second guide pipe 58. The bottom of the first guide pipe 57 is fixedly connected to the second guide pipe 58, and the first guide pipe 57 and the second guide pipe 58 are interconnected. The second guide pipe 58 is placed horizontally, and a second spiral conveying rod 55 is rotatably connected inside the second guide pipe 58. A fifth motor 54 is installed at the right end of the second spiral conveying rod 55. A guide port is opened on the lower left side of the second guide pipe 58, and a guide tube 56 is installed at the guide port. A support plate 3 is provided below the second guide pipe 58, and the support plate 3 is fixedly connected to the outer surface of the second guide pipe 58. The bottom of the support plate 3 is fixedly connected to the fixing frame 2. The left end of the second guide pipe 58 is fixedly connected to the housing 65, and the guide tube 56 is obliquely inserted into the housing 65 and communicates with the housing 65. The turbine fan 66 is located below the guide tube 56.

[0045] Based on the above, the fifth motor 54 drives the second spiral conveyor rod 55 to horizontally convey the feed to the feed inlet, which is then guided by the guide tube 56 and falls into the shell. The feed is then rotated and scattered by the turbine fan 66 below the outlet of the guide tube 56. The stable operation of the entire feed conveying device is ensured by the support plate 3 and the fixed frame 2.

[0046] Furthermore, the horizontal spiral conveyor can precisely control the feed delivery volume, and together with the 66 turbofan engine, it can achieve uniform feed distribution and reduce feed waste.

[0047] Please see Figure 1A handcart 5 is installed at the bottom of the base 4. The handcart 5 includes a handrail 71, a steel frame 72, and casters 73. The upper surface of the steel frame 72 is fixedly connected to the bottom of the base 4, and the casters 73 are fixedly connected to the lower surface of the steel frame 72. The handrail 71 is fixedly connected to the right end of the steel frame 72.

[0048] Based on the above, the casters support 360-degree rotation, and the device is moved by pushing the steel frame through the handlebars.

[0049] Furthermore, the handcart 5 allows for flexible movement, and the feeding position can be adjusted according to the needs of the breeding area, thus improving the applicability of the device.

[0050] In summary, this aquaculture feeding device, during use, has a fixed frame 2 installed on top of the base 4, and a feed cylinder 1 installed on top of the fixed frame 2. The feed inside the feed cylinder 1 is conveyed downwards by the rotation of the first spiral conveyor rod 53. A second spiral conveyor rod 55 is located below the first spiral conveyor rod 53, which horizontally conveys the feed down to the guide pipe 56 at the feed inlet. The feed is then guided by the guide pipe 56 to the spreading mechanism 90. The vortex fan 66 in the spreading mechanism 90 rotates at a uniform speed, causing the feed falling from the guide pipe 56 to be evenly distributed. A collection net 30 is installed below the turbine fan 66. Before feeding, the collection net 30 is unfolded and dropped into the water, and then the feed is scattered. After the aquatic animals finish eating, the collection net rises up to collect the remaining unused feed, reducing pollution of the aquaculture water by residual feed. The collection net 30 is lifted up and down by the first winding mechanism 9 and the second winding mechanism 10 installed at the left and right ends. The collection net 30 is unfolded or retracted by the telescopic mechanism 7 installed on the left side of the fixed plate 8. When retracted, the residual feed already collected in the collection net is further gathered.
