Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a top-mounted feeder for shrimp ponds that prevents backflow of feed during discharge and ensures uniform feeding. Background Technology

[0002] Aquaculture equipment is a general term for all kinds of machinery and equipment used in the entire process of aquatic animal and plant farming, covering multiple aspects such as water quality control, aeration, feeding, harvesting, and water temperature control. For example, aerators can maintain the dissolved oxygen level in the water, filtration equipment can purify the water, and dredging machines are used to remove silt from the bottom of the pond. These devices can improve farming efficiency and reduce labor costs, and are an important support for modern aquaculture.

[0003] Among various aquaculture equipment, shrimp pond feeders are automated feeding devices specifically designed for shrimp farming. By setting the feeding time, frequency, and amount, they evenly distribute shrimp feed into the pond. This equipment, in conjunction with water quality control devices, creates a suitable growth environment for shrimp, further enhancing the scientific nature and efficiency of aquaculture.

[0004] However, in existing technologies, some feeding equipment relies solely on mechanical pushing. On the one hand, for wet or viscous feed, it is easy to adhere and accumulate at the corners and intersections of the conveying pipes, leading to frequent pipe blockages and affecting the continuity of conveying. On the other hand, the lack of targeted wind-resistant design makes it easy for feed to backflow due to headwinds when the external wind direction changes. This not only causes deviations in the amount of feed fed but may also block the conveying channel due to material backflow, making it difficult to adapt to the complex shrimp pond farming environment.

[0005] Therefore, in response to the above problems, a top-mounted feeder for shrimp ponds with the ability to prevent backflow of feed during discharge is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a top-mounted feeder for uniform feeding in shrimp ponds with anti-backflow protection. It aims to improve the problems of some existing feeding equipment, which are prone to sticking and accumulating wet or sticky feed at corners and intersections of the conveying pipes, causing frequent blockages and affecting continuity. In addition, the lack of wind-resistant design means that when the external wind direction changes, backflow can easily cause feed to flow back, resulting in feeding deviations and possible blockage of the channel, making it difficult to adapt to the complex shrimp pond environment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A top-mounted feeder for uniform feeding in shrimp ponds with anti-backflow protection includes a metal frame. A hopper is fixedly connected to the top of the inner wall of the metal frame. A feed pipe is fixedly connected to the output end of the hopper. A spiral blade is installed inside the feed pipe. An air duct is fixedly connected to one side of the feed pipe. A guide plate is also fixedly connected inside the feed pipe. A perforated plate is fixedly connected to the inner wall of the guide plate. An elastic film with vent holes on the surface is fixedly connected to the edge of the perforated plate.

[0009] As a further description of the above technical solution:

[0010] The top of the metal frame is provided with a movable U-shaped tube that can slide along the guide rail;

[0011] As a further description of the above technical solution:

[0012] A material cover is rotatably connected to the top of the metal frame, and a tubular chain reserved opening adapted to the tubular chain conveying system is fixedly connected to the top of the metal frame.

[0013] As a further description of the above technical solution:

[0014] A fan is fixedly connected inside the metal frame, and an air outlet pipe is fixedly connected to the output end of the fan. One end of the material pipe is fixedly connected to one side of the air outlet pipe, and one end of the air conveying pipe is fixedly connected to the bottom of the air outlet pipe.

[0015] As a further description of the above technical solution:

[0016] A motor is fixedly connected to the inner wall of the air outlet pipe, and the outside of the spiral blade is fixedly connected to the drive end of the motor. Four air outlet slots are opened inside the air outlet pipe.

[0017] As a further description of the above technical solution:

[0018] A material distribution plate is fixedly connected to the inside right side of the material tube;

[0019] As a further description of the above technical solution:

[0020] A circuit board is provided on the left side of the metal frame, and an operation screen is provided on the front side of the metal frame.

[0021] As a further description of the above technical solution:

[0022] A material level sensor is fixedly connected to the bottom of the inner wall of the hopper, and the material level sensor is electrically connected to the circuit board.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the airflow generated by the fan is divided into channels. Most of the airflow directly assists the spiral blade in conveying materials, while a small portion forms a strong airflow through the air duct to blow up and vibrate the elastic film. Combined with the guide plate and the perforated plate, it can effectively prevent feed from sticking and clogging at the guide plate, and can also resist the interference of complex external wind directions by the airflow barrier, avoid feed backflow, and significantly improve the stability and wind resistance of material conveying.

[0025] 2. In this utility model, the feeding plate disperses the material into two streams for feeding. Combined with the hanging metal frame and movable U-shaped tube, the feeding range can be flexibly adjusted to adapt to shrimp ponds of different shapes and areas. At the same time, the dual feeding method and the intelligent control system work together to achieve precise control of the feeding amount and time, which not only ensures that the feed is evenly distributed in all areas of the shrimp pond, but also greatly reduces labor costs, taking into account both breeding efficiency and economy.

[0032] 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.

[0033] Reference Figures 1 to 4 This utility model provides an embodiment of a top-mounted feeder for shrimp ponds with anti-backflow feeding and uniform feeding. It includes a metal frame 1, which serves as the basic support for the entire device. The top-mounted design adapts to shrimp pond installation scenarios, ensuring stable operation of all structures, high stability over long-term use, and reducing malfunctions and maintenance costs. The top of the metal frame 1 is equipped with a movable U-shaped tube 2 that can slide along a guide rail, allowing for position adjustment and adjustment of the feeding range to suit shrimp ponds of different shapes and areas. This overcomes the limitations of fixed-position feeders and is compatible with pipe chain conveying systems for continuous material transport. A material cover 3 is rotatably connected to the top of the metal frame 1, facilitating manual feeding when opened. A hopper 4 is fixedly connected to the top of the inner wall of the metal frame 1 to temporarily store feed, providing a source for material transport. A level sensor at the bottom of the inner wall can monitor the remaining material level in real time.

[0034] The top of the metal frame 1 is fixedly connected to a pre-reserved tube chain port 5 adapted to the tube chain conveying system, which is compatible with the tube chain conveying system to achieve automatic material replenishment and continuous material conveying by connecting with the tube chain conveying system. The output end of the hopper 4 is fixedly connected to a material pipe 6, which serves as a material conveying channel and carries the material from the hopper 4 to the feeding end, ensuring the material conveying path. The inside of the metal frame 1 is fixedly connected to a fan 7, which generates airflow and provides wind power assistance for material conveying. It is controlled in conjunction with the motor 9, reducing energy consumption by 40% compared with similar equipment, showing significant energy-saving advantages. The output end of the fan 7 is fixedly connected to an air outlet pipe 8, which diverts the airflow generated by the fan 7. The four air outlet slots opened inside optimize the air pressure distribution. Part of the airflow enters the material pipe 6 to assist in conveying, and the other part is introduced into the air conveying pipe 11 through the bottom slot.

[0035] One end of the material pipe 6 is fixedly connected to one side of the air outlet pipe 8, receiving the airflow diverted by the air outlet pipe 8 to assist in material conveying; a motor 9 is fixedly connected to the inner wall of the air outlet pipe 8, driving the spiral blade 10 to rotate, providing mechanical power for material conveying, and coordinating with the fan 7 to improve conveying efficiency; the spiral blade 10 is installed inside the material pipe 6, which, when rotating, conveys the material output from the hopper 4 forward along the material pipe 6, and, with the assistance of airflow, achieves stable material pushing; the outside of the spiral blade 10 is fixedly connected to the drive end of the motor 9. The motor 9 receives power to rotate the air pipe; the air outlet pipe 8 has four air outlet slots inside to optimize the air pressure distribution and make the airflow more evenly distributed to the material pipe 6 and the air conveying pipe 11; the air conveying pipe 11 is fixedly connected to one side of the material pipe 6, and its diameter is much smaller than that of the material pipe 6, so that the internal airflow intensity is stronger and the airflow diverted by the air outlet pipe 8 is introduced into the material pipe 6 from the other side and blown towards the elastic film 14; one end of the air conveying pipe 11 is fixedly connected to the bottom of the air outlet pipe 8, receives the airflow diverted by the air outlet pipe 8 and guides it into the material pipe 6.

[0036] Inside the feed pipe 6, a guide plate 12 is fixedly connected to guide the airflow from the air duct 11 to act on the perforated plate 13, ensuring airflow and effectively directing the airflow towards the elastic membrane 14. The inner wall of the guide plate 12 is fixedly connected to the perforated plate 13, allowing the airflow to act evenly on the elastic membrane 14, causing the elastic membrane 14 to bulge when the airflow passes over it. The edge of the perforated plate 13 is fixedly connected to the elastic membrane 14, which is blown up by the strong airflow and continuously vibrates slightly, preventing feed from adhering to the guide plate 12 and avoiding pipe blockage at intersections. When there is a headwind, the airflow blown by the blower 7 resists the headwind, preventing feed backflow and resisting interference from complex external wind directions. Inside the feed pipe 6, on the right side, a distribution plate 15 is fixedly connected to distribute the material into two streams for delivery, ensuring even distribution of feed in all areas of the shrimp pond, reducing feed waste and water pollution, and promoting uniform growth of shrimp.

[0037] A circuit board 16 is located on the left side of the metal frame 1. It receives signals from the level sensor, processes instructions from the operation screen 17, and controls the operation of the motor 9 and the fan 7 to achieve automated operation of the equipment. It supports parameter preset and status monitoring. A level sensor is fixedly connected to the bottom of the inner wall of the hopper 4 to detect the remaining material in the hopper 4 in real time and transmit the information to the circuit board 16 to achieve material remaining monitoring. The level sensor is electrically connected to the circuit board 16 to achieve information transmission and ensure that the circuit board 16 has real-time control over the remaining material. An operation screen 17 is located on the front side of the metal frame 1 to display information such as equipment operating status and remaining material. It supports setting parameters such as feeding speed, time, and number of meals to achieve intelligent control and facilitate user operation and monitoring. Together with the front-end tubular chain feeding device, it enables one person to manage hundreds of acres of shrimp ponds.

[0038] Working Principle: In conventional material conveying, the motor 9 drives the spiral blade 10 to rotate, thereby conveying the material output from the hopper 4 forward along the material pipe 6. Regarding backwind prevention and material conveying stability, through the cooperation of the air duct 11, guide plate 12, perforated plate 13, and elastic membrane 14, most of the airflow blown by the blower 7 is blown into the interior of the material pipe 6 through the through-slot, thus assisting the spiral blade 10 in subsequent material conveying. Airflow is introduced into the air duct 11 through the through-slot at the bottom of the outlet duct 8, and subsequently blown into the material pipe 6 from the other side. Because the diameter of the air duct 11 is much smaller than that of the material pipe 6, the airflow blown from the air duct 11 is stronger than that blown directly into the material pipe 6, thus overcoming wind resistance, blowing up the elastic membrane 14, and causing it to vibrate slightly continuously, effectively preventing feed from adhering to the guide plate 12 and avoiding pipe blockage at intersections. The vent holes on the surface of the elastic membrane 14 ensure that the blown airflow can be released in time, preventing the elastic membrane 14 from bursting. At the same time, because it is a wind-assisted material conveying system, it also reduces the impact of complex external wind directions on the materials to a certain extent, prevents feed backflow, ensures the continuous and stable conveying process, and solves the problem of feeding deviation of existing equipment in complex wind environment.

[0039] In terms of feeding uniformity and adaptability, the feeding plate 15 disperses the material into two streams for feeding. Combined with the hanging metal frame 1 and the movable U-shaped tube 2, the feeding range can be adjusted to adapt to shrimp ponds of different shapes and areas. This breaks through the limitations of fixed-position feeding machines, ensuring that the feed is evenly distributed in all areas of the shrimp pond, reducing feed waste and water pollution caused by uneven feeding, and promoting uniform growth of shrimp.

[0040] In terms of intelligence and efficiency, the combination of the material level sensor, circuit board 16, and operation screen 17 enables the monitoring of the remaining material inside the hopper 4, parameter preset (feeding speed, time, number of meals), and monitoring of the operating status. Simultaneously, there are two feeding methods: manual opening of the feed cover 3 for feeding, or automatic feeding via the tubular chain conveyor system with the pre-reserved opening 5, allowing one person to manage hundreds of acres of shrimp ponds, significantly reducing labor costs. The coordinated control of the motor 9 and the fan 7 reduces energy consumption by 40% compared to similar equipment, demonstrating significant energy-saving advantages. Furthermore, the equipment has a reasonable structural layout, high long-term operational stability, reduces malfunctions and maintenance costs, and overall improves the scientific and economic benefits of aquaculture.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
