Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an automatic feeding device for freshwater fish farming. Background Technology

[0002] Freshwater fish farming refers to the planned rearing, breeding, and management of fish in artificially controlled or semi-controlled freshwater environments to obtain aquatic products. This process involves not only the farming of fish but also the farming of other aquatic organisms such as shrimp, crabs, and shellfish. During freshwater fish farming, the growth of freshwater fish requires sufficient nutrition, and feeding provides the necessary nutrients such as protein, fat, and vitamins.

[0003] In existing technologies, granular feed in traditional hoppers is prone to clumping due to gravity, which can block the feed pipe and interrupt feeding. Currently, most aquaculture operations use blowers to deliver feed, using airflow to propel it through pipes. However, this method has significant drawbacks: the violent collision between high-speed airflow and feed particles generates a large amount of broken feed, reducing feed utilization and causing it to decompose and pollute the water after settling at the bottom. Furthermore, broken feed powder easily adheres to the inner wall of the pipes, accumulating over time and increasing the risk of blockages, while also increasing equipment maintenance frequency. Therefore, we propose an automatic feeding device for freshwater fish farming to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding device for freshwater fish farming.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeding device for freshwater fish farming includes a hopper, an inner plate fixedly connected to the hopper, a first motor fixedly connected to the top of the inner plate, a drive rod fixedly connected to the bottom of the output shaft of the first motor, two connecting rods fixedly connected to the outer wall of the drive rod, one end of the two connecting rods fixedly connected to the same inclined dispersing rod, a feed pipe fixedly connected to the bottom of the hopper, an electronic valve fixedly installed on the outer wall of the feed pipe, a venturi tube fixedly connected to the bottom of the feed pipe, a rubber water pipe fixedly connected to one end of the venturi tube, a water pump fixedly connected to one end of the rubber water pipe, a connecting pipe fixedly connected to the other end of the venturi tube, and a feeding assembly provided at one end of the connecting pipe.

[0007] Preferably, the feeding assembly includes a feeding frame, one end of the connecting pipe is fixedly connected to the outer wall of the feeding frame, a second motor is fixedly connected to the top of the feeding frame, and multiple feeding blades are fixedly connected to the bottom outer wall of the output shaft of the second motor. When the multiple feeding blades rotate, they can evenly disperse and scatter the bait mixed with water into the fishpond.

[0008] Preferably, the outer wall of the mounting plate has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the first motor. The rotation of the output shaft of the first motor provides power to the drive rod, the connecting rod and the inclined dispersion rod.

[0009] Preferably, a U-shaped frame is fixedly fitted on the top of both the first motor and the second motor, and the bottom of the two U-shaped frames is fixedly connected to the top of the mounting plate and the feeding frame, respectively. The U-shaped frames increase the stability of the first motor and the second motor during operation.

[0010] Preferably, the top of the feeding frame is provided with a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the second motor.

[0011] Preferably, the inclined dispersing rod is located inside the hopper.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses an inclined dispersing rod to disperse the bait in the hopper in real time, preventing clumping due to gravity. Combined with the low-pressure adsorption principle of the Venturi tube, it can smoothly guide the bait into the connecting pipe, reducing the risk of blockage in the feed pipe and conveying pipeline from the source, ensuring the continuity of the feeding process, and reducing manual cleaning costs. The water pumping and bait mixing conveying mode, with the gentle pushing action of the water flow, greatly reduces the collision force between bait particles, maximizing the preservation of bait integrity, reducing the risk of water pollution, and also preventing powder from adhering to the inner wall of the pipe.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, an automatic feeding device for freshwater fish farming is disclosed, comprising a hopper 1, a mounting plate 2 fixedly connected inside the hopper 1, a first motor 3 fixedly connected to the top of the mounting plate 2, a through hole on the outer wall of the mounting plate 2, the inner wall of the through hole being rotatably connected to the outer wall of the output shaft of the first motor 3, a drive rod 4 fixedly connected to the bottom of the output shaft of the first motor 3, two connecting rods 5 fixedly connected to the outer wall of the drive rod 4, and a common inclined dispersing rod 6 fixedly connected to one end of the two connecting rods 5. The inclined dispersing rod 6 is located inside the hopper 1. The rotation of the output shaft of the first motor 3 provides power to the drive rod 4, the connecting rods 5 and the inclined dispersing rod 6, driving the inclined dispersing rod 6 to disperse the feed in the hopper 1.

[0021] A feed pipe 7 is fixedly connected to the bottom of the feed hopper 1. An electronic valve 8 is fixedly installed on the outer wall of the feed pipe 7. The electronic valve 8 controls the opening and closing of the feed pipe 7. A venturi tube 9 is fixedly connected to the bottom of the feed pipe 7. A rubber water pipe 10 is fixedly connected to one end of the venturi tube 9. A water pump 11 is fixedly connected to one end of the rubber water pipe 10. The rubber water pipe 10 ensures that the water pumped by the water pump 11 is smoothly delivered to the venturi tube 9, providing a stable water flow for mixing feed and water. A connecting pipe 12 is fixedly connected to the other end of the venturi tube 9.

[0022] As the water flows through the gradually narrowing path inside the Venturi tube 9, the flow velocity increases and the pressure decreases. A low-pressure zone is formed in the narrow section, which produces an adsorption effect. This allows the feed falling from the feed pipe 7 to be smoothly sucked in and mixed with the water flow. The feed is then transported by the propulsion of the water flow, effectively preventing blockages during the transport process.

[0023] One end of the connecting pipe 12 is provided with a feeding assembly, which includes a feeding frame 13. One end of the connecting pipe 12 is fixedly connected to the outer wall of the feeding frame 13. A second motor 14 is fixedly connected to the top of the feeding frame 13. A U-shaped frame 16 is fixedly fitted on the top of both the first motor 3 and the second motor 14. The bottom of the two U-shaped frames 16 is fixedly connected to the top of the mounting plate 2 and the feeding frame 13, respectively. A round hole is opened on the top of the feeding frame 13. The inner wall of the round hole is rotatably connected to the outer wall of the output shaft of the second motor 14. Multiple feeding blades 15 are fixedly connected to the bottom outer wall of the output shaft of the second motor 14.

[0024] The feeding frame 13 provides space for the final feeding of the bait, and the mixed bait delivered by the connecting pipe 12 is temporarily stored here; the second motor 14 provides power to the feeding blades 15, driving them to rotate; when multiple feeding blades 15 rotate, they can evenly disperse and scatter the bait mixed with water into the fishpond, expanding the feeding range and enabling the fish in the fishpond to feed more evenly.

[0025] Working principle: When in use, the bait is placed in the hopper 1. As the first motor 3 operates, it drives the drive rod 4 and the two connecting rods 5 to rotate. The rotation of the two connecting rods 5 drives the inclined dispersing rod 6 to disperse the bait, preventing it from piling up in one place and facilitating its subsequent entry into the feed pipe 7. With the opening of the electronic valve 8, the bait in the feed pipe 7 is fed into the venturi pipe 9. As the water pump 11 operates, external water is pumped into the venturi pipe 9 through the rubber water pipe 10. The water mixed with the bait enters the connecting pipe 12 through the venturi pipe 9. As the water flows through the gradually narrowing path inside the venturi pipe 9, the flow rate increases and the pressure decreases, thus forming a low-pressure zone in the narrow part, thereby generating an adsorption effect. This makes it easier to feed the bait into the connecting pipe 12 located in the narrow part, avoiding blockage. The bait mixed with water enters the feeding frame 13. With the operation of the second motor 14, multiple feeding blades 15 rotate, dispersing the water and bait into the fishpond.

[0026] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the first motor 3, the electronic valve 8, the water pump 11, and the second motor 14 to facilitate overall control.
