Description

Technical Field

[0001] This utility model relates to the technical field of feeding equipment in shrimp factory farming workshops, and is an automatic feeding system suitable for shrimp farming workshops. Background Technology

[0002] Statistics show that the mainstream shrimp farming method currently uses a closed recirculating aquaculture system, which improves water quality and optimizes discharge treatment compared to traditional methods, thereby increasing shrimp survival rates. However, the feeding process in this model still mostly relies on manual labor, requiring manual handling of feed, weighing, and spreading. This results in high labor intensity, low feeding accuracy, high labor costs, and a negative impact on overall farming efficiency.

[0003] Some aquaculture farms use self-made feeders for feeding. The main support structure of such feeders has many disadvantages: (1) The structure is unstable, which affects the stability of the system; (2) All key devices are exposed to a humid environment, which reduces the lifespan and aesthetics of the materials; (3) All pipelines are difficult to maintain; (4) There is a risk of biosecurity when the feed gets damp; (5) The feed hopper has a small volume, the feeding frequency is high, and the manual labor intensity is high; (6) The concentrated feeding method makes it easy for shrimp to compete for food, which is not conducive to the growth of the shrimp population; (7) The installation method causes shrimp to jump, which increases working time and management costs; (8) The pipelines and cables are not arranged reasonably, which makes it easy to have leakage accidents. Therefore, this technology is rarely used at present. The reason is that it has low integration, messy pipelines, difficulty in loading, complex operation, low accuracy, inconvenient installation and disassembly, and incomplete realization of the required functions. It is not enough to meet the needs of fully automatic feeding function and does not conform to the current equipment manufacturing industry concept of "simple and easy to use".

[0004] With the development of feeding technology, newly designed aquaculture feeding equipment has also emerged. For example, Chinese invention patent document CN104782552A, published on July 22, 2015, discloses a centralized automatic feeding and aeration system for aquaculture. This system sets up a feeding station for each of several adjacent ponds; a group of combined feed silos serves as a feed storage warehouse, directly receiving feed from feed trucks; a lifting feeder elevates the feed, which is then distributed from top to bottom into the various silos of the combined feed silo group via a distributor; a high-pressure blower serves as a power source, connected to the discharge duct, and the discharge air... The pipes are connected to the feeder and the aeration pipe via pneumatic tees. The feeder floats on the water surface, and a pair of feed nozzles on it rotate under air pressure, spraying the feed in a ring onto the water surface. The aeration pipe, located underwater in the feeder's feeding area, aerates the water in the feeding area, increasing the dissolved oxygen demand of the densely feeding fish and improving the feeding effect. The weighing unit weighs the feed and monitors the amount of feed added. The control unit uses PLC intelligent control to centrally control feed addition and aeration. However, this type of feeding equipment is only suitable for fish farming and not for shrimp farming. For example, Chinese utility model patent document CN209403315U, published on September 20, 2019, discloses a gantry-type factory-style aquaculture feeding device. This device is also suitable for fish farming, but it uses a gantry frame design, has a complex structure, and is not suitable for use in large-area aquaculture ponds. For example, Chinese utility model patent document CN205018084U, published on February 10, 2016, discloses an automatic feeder for an aquaculture feeding machine, including a feed bin, a feed bin support, and a self-priming feeder. The feed bin is installed on the feed bin support, and the self-priming feeder is installed on the top of the feed bin. The self-priming feeder is connected to external feed through a feed pipe. It also includes a vibrating feeder, a feed pipe, a pneumatic feeder, and a control cabinet. The vibrating feeder is installed at the bottom of the feed bin and is used to shake the feed in the feed bin into the feed pipe. The pneumatic feeder is installed on the side of the vibrating feeder and is used to transport the feed that falls into the feed pipe to the feeding machine along the feed pipe. The control cabinet is electrically connected to the self-priming feeder, the vibrating feeder, and the pneumatic feeder respectively and is used to control the operation of the self-priming feeder, the vibrating feeder, and the pneumatic feeder. The equipment mainly features improvements to the feeding and conveying processes, which have improved these issues to some extent. However, the overall equipment design is not precise enough, and the automatic material feeder is located on top of a large storage bin, posing a certain safety hazard. Additionally, it has issues with inaccurate material delivery and spreading.

[0005] The above-mentioned technologies cannot meet the needs of existing shrimp factory farming workshops. Therefore, it is necessary to design an automatic feeding device that can integrate automatic feeding, precise feed weighing, distribution of feed to each farming pond, reasonable and even spreading of feed, high safety, and no risk of biological control. Utility Model Content

[0006] This utility model discloses an automatic feeding system suitable for shrimp farming workshops. Through automated control, it realizes the functions of feeding, weighing, and distributing feed. Finally, the feed is evenly scattered by a feeding track trolley installed on the track above the farming pond. It realizes the automated feeding functions of feeding, weighing, distributing, and scattering feed. It is suitable for shrimp recirculating aquaculture system, and can feed accurately at fixed times and in fixed quantities. It greatly reduces labor and management costs, improves the safety of the entire feeding equipment, reduces the risk of biosecurity, preserves feed well, and maintains a good hygiene environment in the farming pond.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] An automatic feeding system suitable for shrimp farming workshops includes a differential weight feeder, an automatic feeding track trolley, a track system, and a control unit. The control unit controls the differential weight feeder to perform feed suction and feeding operations. After the feed is fed into the automatic feeding track trolley, the control unit controls the automatic feeding track trolley to move with the track system and feed each shrimp farming pond in the workshop it passes through, stopping above the shrimp farming pond to be fed as required.

[0009] The track system adopts a Type I steel structure track, which extends from the lower end of the differential feeder and is arranged along the pedestrian passage between the shrimp farming ponds. Each shrimp farming pond end is equipped with a position information reflector along the direction of travel of the automatic feeding track trolley. Position information reflectors are installed at the origin, near origin, middle, and end points of the track.

[0010] The automatic feeding trolley includes a trolley wheel set, a hopper frame, and multiple hoppers. The hoppers are all installed inside the hopper frame, which is installed below the trolley wheel set. The trolley wheel set is fixed on the track and can carry the hoppers and the hopper frame together to move along the track. A laser position sensor set is installed on one side of the hopper frame, and the laser position sensor set is highly matched with the position information reflector.

[0011] The differential weight feeder is equipped with a suction device, a weighing and discharging device, and a control unit. The suction device includes a vacuum suction machine, a vacuum tube, and a vacuum chamber. The vacuum suction machine's airflow is connected to the vacuum chamber through the vacuum tube. The suction port of the vacuum chamber is connected to the feed storage area through the suction pipe, and the discharge port at the bottom of the vacuum chamber is connected to the feeding pipe. The airflow direction of the suction pipe and vacuum tube in the suction device is consistent with the airflow direction of the vacuum suction machine's fan. The weighing and discharging device includes, from top to bottom, a collection bin, a metering bin, and a screw conveyor. The inlet at the top of the collection bin is connected to the feeding pipe of the suction device, and the discharge port at the bottom of the collection bin is connected to the inlet at the top of the metering bin through a butterfly valve. The discharge port at the bottom of the metering bin is connected to the inlet of the screw conveyor through a discharge pipe, and the discharge port of the screw conveyor is connected to the main discharge pipe. A feed switching electric valve is installed inside the discharge pipe, and the discharge direction of the feed switching electric valve is perpendicular to the main discharge pipe.

[0012] The control unit performs linkage control on each controlled component according to the logic program or feedback signal, controls the opening or closing of each valve and other components, and realizes the automatic execution of feeding, weighing, dropping, feeding and distribution of the entire feeding system. When the bait dropped from the weighing and dropping device enters the screw conveyor, the control unit controls the opening and closing and direction distribution of the feeding switching electric valve, and distributes the bait in the main discharge pipe to the designated automatic feeding track trolley hoppers to realize the loading.

[0013] The further design of the track system is as follows:

[0014] Furthermore, the contact part between the track system and the drive wheel of the automatic feeding track trolley is made of stainless steel, while the rest is made of carbon steel.

[0015] Furthermore, a mechanical hard stop is installed at the end of the track.

[0016] Furthermore, the track is fixed by welding supporting steel beams; the supporting steel beams are welded and fixed to the existing pipeline support frame in the workshop; and welded triangular supporting steel beams are used to fix the track within the shrimp farming pond area.

[0017] The further design of the automatic feeding track trolley is as follows:

[0018] Furthermore, a stainless steel discharge valve is installed at the bottom of each hopper, and the valve flap is equipped with a flexible baffle. The size of the baffle matches the discharge port of the valve. The tilt angle of the flap is >50° and the inner wall is smooth to facilitate material discharge.

[0019] Furthermore, the hopper frame is custom-made from stainless steel.

[0020] Furthermore, the sports car wheel assembly includes a running wheel and a fixed axle, and the sports car wheel assembly and the servo motor are connected by a drive gear.

[0021] The trolley wheel set is located at the center of the load-bearing position on the hopper frame. The hoppers are arranged on both sides of the hopper frame with the trolley wheel set as the center line, ensuring that the hoppers and hopper frame can move stably and safely along the track with the trolley wheel set.

[0022] Furthermore, the automatic feeding trolley uses a servo motor as the drive unit, a power lithium battery is installed under the hopper frame, and an automatic charging contact is installed at the end of the hopper frame. The charging contact matches the charger contact configured in the feeding system.

[0023] The further design of the differential feeder is as follows:

[0024] Furthermore, the vacuum feeder fan is timed using a control module and can be a vortex high-pressure fan. It uses its own cavity to create a vacuum, drawing bait from the outside through the pipeline into the vacuum cavity for feeding and vacuuming.

[0025] Furthermore, an inclined baffle plate is installed inside the feeding pipe to prevent backflow from entering the material discharge line.

[0026] Furthermore, the material collection silo is equipped with a level gauge and a low-level alarm; the weighing and unloading device is integrally mounted on a fixed frame, with the screw conveyor and metering sensor located above the operating platform for easy operation or maintenance by personnel. The oil-water separator is installed below the operating platform.

[0027] When the vacuum feeder is working, a vacuum is drawn from the vacuum chamber to create a negative pressure airflow, which causes the bait to be sucked into the vacuum chamber through the suction pipe. Inside the vacuum chamber, the bait falls to the bottom of the vacuum chamber by its own gravity and will not be sucked out of the vacuum chamber with the airflow. At the same time, when the bait at the bottom of the vacuum chamber falls out through the feeding pipe, the inclined wind baffle prevents backflow from entering the feeding pipe. The bait falls all the way down the feeding pipe and is finally sent into the hopper of the automatic feeding trolley by the feeding switching electric valve.

[0028] Furthermore, the control unit includes at least a chassis and a frame for fixing the chassis. The chassis is used to mount the cable tray, PLC, electrical control components, and embedded industrial control touch screen. The frame is fixed in a safe and easily accessible area according to the workshop layout. Through the intelligent control program of the control unit, the opening and closing of electrical components such as electric valves, solenoid valves, and servo motors are controlled. Based on logic programs or feedback signals, the various controlled components are linked for coordinated control, enabling the entire system to automatically perform tasks such as feeding, weighing, and distributing materials. Operators can select relevant system parameters through the industrial control touch screen, such as specifying the feeding position and feeding quantity, and can also observe the system's operation through the touch screen, achieving human-machine interaction.

[0029] Furthermore, the chassis can be made of stainless steel or powder-coated carbon steel, which is moisture-resistant, oxidation-resistant, stable and reliable, and is formed by welding sheet metal to the frame.

[0030] The beneficial effects of this utility model are as follows:

[0031] This invention integrates feeding, weighing, and discharging into a single equipment room with a rational assembly, stable and robust overall structure, compact design, and convenient operation. It prevents feed from remaining in pipes, causing mold and posing a risk to biosecurity, and significantly improves the system's moisture and rust resistance. A reverse conveying method using vacuuming effectively achieves automatic feeding, loading, and storage in the hopper. The rationally designed weighing and discharging system accurately weighs the required amount of feed and precisely dispenses it into the hopper of the automatic feeding trolley. The automatic feeding trolley's laser sensor array detects the position of reflectors on the track, corresponding to each aquaculture pond, ensuring accurate and uniform feeding. The entire system is controlled by a control unit, enabling safe and reliable precise feeding. Attached Figure Description
