Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an automatic feeding system suitable for factory-scale aquaculture workshops, used to realize the automatic feeding and replenishment of feed during the aquaculture process. Background Technology

[0002] Currently, aquaculture in my country is mainly conducted in outdoor ponds, which are greatly affected by geographical environment, seasonal factors, and water source conditions. Factory-style aquaculture, with its unique advantages, can avoid these factors and is gradually becoming an important direction for industry upgrading. In factory-style recirculating aquaculture, the frequent feeding frequency can bring huge benefits to the growth rate of aquatic products. However, most current feeding processes still rely on manual labor, requiring manual transport, metering, and spreading of feed. This results in high labor intensity, low feeding accuracy, high labor costs, and a negative impact on overall aquaculture efficiency.

[0003] In existing factory-style aquaculture, the feeding systems that are widely used still require manual handling of feeding, loading, and metering, such as wall-mounted feeders. These systems cannot achieve systematic automatic control and have not truly reduced the manual input in feeding.

[0004] Existing feeder tray technology is mature, stable, and widely used in the livestock and poultry farming industry, but it has not been applied to the factory-scale aquaculture industry, such as for multiple feed lines in a single pigsty to achieve timed and quantitative feeding and improve the personalized feeding effect for pigs. Due to the high precision requirements for feeding, feeder tray technology has not yet been applied to the feeding system of factory-scale aquaculture.

[0005] Therefore, the feeder plate feeding technology can be applied to the feeding and dispensing of industrialized aquaculture. By integrating the two technologies, an automatic feeding device can be designed that integrates automatic feeding and transportation, distribution of feed to each breeding pond, reasonable and uniform spreading of feed, and high safety, in order to reduce the manual input of feeding in industrialized aquaculture. Utility Model Content

[0006] This utility model discloses an automatic feeding system suitable for factory-scale aquaculture workshops. Through automated control, it achieves feed intake and distribution, and finally, feed is evenly scattered through suspended nozzles in the aquaculture pond via pneumatic conveying. This realizes automated feeding functions for feeding, transporting, distributing, and scattering. By precisely controlling the amount and speed of feed, it reduces feed waste and improves feed utilization. It is suitable for shrimp recirculating aquaculture systems, allowing for precise, timed, and quantitative feeding, greatly reducing labor and management costs, improving the safety of the entire feeding equipment, ensuring good feed preservation, and maintaining a hygienic feeding environment in the aquaculture pond.

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

[0008] An automatic feeding system suitable for factory-scale aquaculture workshops includes an automatic feeding unit, an automatic conveying unit, and an automatic feeding unit. The automatic feeding unit picks up feed from the feed placement area, the automatic conveying unit transports the feed picked up by the automatic feeding unit to the aquaculture pond, and the automatic feeding unit provides precise feeding at regular intervals and in fixed quantities.

[0009] The automatic feeding unit is equipped with a feeding pipe, a vacuum feeder, and a discharging pipe. One end of the feeding pipe is connected to the bait placement area, and the other end of the feeding pipe is connected to the feed inlet of the vacuum feeder. The discharge outlet of the vacuum feeder is connected to the hopper of the automatic feeding unit through the discharging pipe.

[0010] The automatic feeding unit is equipped with a hopper, a feeding control unit, a feeding auger, and a disc feed line. The disc feed line includes a chain driver, a disc main unit, a feeding circulation pipe, and auxiliary pipes. A feeding auger is installed at the outlet of the hopper. The outlet of the feeding auger is connected to the disc main unit via a chain driver. The outlet of the disc main unit is connected to an upward-facing vertical pipe via a low horizontal pipe. The top of the vertical pipe is connected to a feeding circulation pipe located horizontally above the aquaculture pond. The end of the feeding circulation pipe returns to the inlet of the feeding auger via an inclined pipe. Each corner of the disc feed line is equipped with a disc corner to prevent feed from clogging at the pipe corners.

[0011] In the automated material handling unit, the feed falling from the hopper is carried into the disc feed line by a feeding auger. Driven by a chain drive, the chain in the disc feed line moves through a chain turntable, extending the pipeline of the disc feed line into the workshop.

[0012] The automatic feeding unit includes a metering bin, a pneumatic conveying device, a feeder, a discharge pipe, and a feeding nozzle. Within the workshop, several aquaculture ponds are arranged according to the workshop layout. Each pond has a corresponding discharge port on its feed line pipe, and a metering bin is located below each discharge port. The feed in the feed line is carried by a chain to the area above each aquaculture pond, and then enters the metering bin through the discharge port of the feed line pipe above the pond, thus realizing the transport of feed.

[0013] Furthermore, the inclination angle of the hopper's inclined surface in the hopper is >45° to facilitate smooth material discharge.

[0014] Furthermore, the pneumatic conveying device includes a blower, an air supply pipe, and an air pressure detection device. The air supply pipe includes a main air pipe and several branch air pipes. The front end of the main air pipe is connected to the blower, and air pressure detection devices can be installed at the ends of the main air pipe and branch air pipes, depending on the specific situation. Each metering container is equipped with a set of branch air pipes, a feeder, a discharge pipe, and a feeding nozzle, which delivers the air from the main air pipe to the corresponding discharge pipe. By detecting the air pressure, subsequent actions are performed after determining that the air pressure is sufficient, realizing the pneumatic conveying of the bait and effectively avoiding uneven bait spraying caused by low air pressure.

[0015] Furthermore, the upper end of the feeder is connected to the discharge port at the bottom of the metering container, and the lower end of the feeder is connected to the discharge pipe via a main pipe of a slanted tee. The branch pipe of the slanted tee is connected upwards to a branch air duct, and a ball valve for adjusting the airflow is installed near the branch air duct. The lower end of the discharge pipe is connected to a feeding nozzle via a union joint. In this way, the feeder is responsible for delivering the feed from the metering container into the discharge pipe, achieving feed spraying.

[0016] When the feeding control unit sets the time, the fan starts and the air pressure detection at the end of the air supply pipe is activated. After detecting a certain air pressure value, the control unit controls the feeder to operate. The feeder starts and slowly sends the feed in the metering bucket into the feeding pipe. The feed meets the air in the feeding pipe and is blown to the feeding nozzle to achieve uniform and spaced feeding. After the feeder reaches the set value, the control unit controls the feeder and the fan to stop working, the feeding process ends, and the entire system waits for the next feeding.

[0017] Furthermore, the feeder includes a feeding motor and a rotating drum. The feeding motor drives the rotating drum, and the rotating drum causes the feed inside the feeder to rotate and be fed into the main pipe of the inclined tee.

[0018] Furthermore, the automatic feeding unit is equipped with a feeding control unit, which includes at least a control box and a cable tray, a fixing frame, a PLC, electrical control components, and an embedded industrial control touch screen installed in the control box. The feeding control unit mainly controls the total amount of material fed and the feeding time.

[0019] Furthermore, the feeding control unit and the conveying control unit are independent of each other, which improves the accuracy of automatic feeding.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model combines the material transport process and the feeding process. The entire system is controlled by a control unit, which can safely and reliably carry out precise feeding. By accurately controlling the feeding amount and feeding speed, feed waste is reduced and feed utilization is improved.

[0022] 2. When this utility model is applied in a factory-style aquaculture workshop, only manual assistance is required for feeding, system parameter input, and system maintenance, which greatly saves labor costs.

[0023] 3. In this utility model, the feed is transported and fed in a closed space at each stage, which is isolated from the humid environment of the aquaculture factory workshop, effectively preventing the feed from becoming moldy.

[0024] 4. The feed is delivered using a controllable airflow at the feeding end, which, together with the adjustable-angle feed nozzle, can effectively spray the feed into the aquaculture pond according to the aquaculture needs. Attached Figure Description

Detailed Implementation

[0032] Example 1

[0033] like Figure 1 As shown, this utility model provides an automatic feeding system suitable for factory-scale aquaculture workshops, including an automatic feeding unit, an automatic conveying unit, and an automatic feeding unit. The automatic feeding unit picks up feed from the feed placement point, the automatic conveying unit transports the feed picked up by the automatic feeding unit to the aquaculture pond, and the automatic feeding unit performs precise feeding at regular intervals and in fixed quantities.

[0034] The automatic feeding unit is equipped with a feeding pipe, a vacuum feeder, and a discharging pipe. One end of the feeding pipe is connected to the bait placement area, and the other end is connected to the inlet of the vacuum feeder. The outlet of the vacuum feeder is connected to the hopper 1 of the automatic conveying unit through the discharging pipe. The automatic feeding unit is responsible for suction and feeding, sucking up bait from the bait placement area and then using air force to deliver the sucked bait along the pipe to the hopper of the automatic conveying unit.

[0035] The automatic feeding unit is equipped with a feed hopper 1, a feeding control unit, a feeding auger 2, and a disc feeding line. The disc feeding line includes a chain driver, a disc host 301, a feeding circulation pipe, and corresponding auxiliary pipes. The feeding auger 2 is installed at the discharge port of the feed hopper 1. The discharge port of the feeding auger 2 is connected to the disc host 301 via a chain driver. The discharge port of the disc host 301 is connected to an upward-facing vertical pipe via a low horizontal pipe. The top of the vertical pipe is connected to a feeding circulation pipe located horizontally above the aquaculture pond. The end of the feeding circulation pipe returns to the inlet of the feeding auger 2 via an inclined pipe. Each corner of the disc feeding line is equipped with a disc chain turntable 302 to prevent feed from clogging at the pipe corners.

[0036] In the automatic feeding unit, the feed falling from the feed hopper 1 is carried into the feed tray line by the feeding auger 2. Driven by the chain driver, the chain turntable 302 moves the chain inside the feed tray line, extending the feed tray line pipe into the workshop and moving the feed to the feed tray line pipe above the breeding pond 10. The feeding control unit controls the timing of feeding based on feedback information from the feeding control unit.

[0037] The automatic feeding unit includes a metering bin 5, a pneumatic conveying device, a feeder 6, a discharge pipe 8, and a feeding nozzle 9. The pneumatic conveying device includes a blower, an air supply pipe, and an air pressure detection device. The air supply pipe includes a main air pipe and branch air pipes.

[0038] In this embodiment:

[0039] The workshop is equipped with two rows of breeding ponds 10. Above each row of ponds 10 is a pneumatic conveying system. This system includes a blower 401, a main air duct 402, several branch air ducts 403, and a wind pressure detection device 404. The front end of the main air duct 402 is connected to the blower 401, and the end of the main air duct 402 is also equipped with a wind pressure detection device 404. By detecting the wind pressure, the system determines that sufficient pressure is required before proceeding with subsequent actions, thus achieving pneumatic conveying of the feed and effectively preventing uneven feed spraying due to low wind pressure.

[0040] Each aquaculture pond 10 in the workshop is equipped with a metering tank 5. Feed from the feed tray is pulled by a chain to the top of the aquaculture pond 10, and then enters the metering tank 5 through the discharge port of the pipe above the pond 10, thus transporting the feed. Each metering tank 5 is equipped with a branch duct 403, a feeder 6, a discharge pipe 8, and a feeding nozzle 9. The upper end of the feeder 6 is connected to the discharge port at the bottom of the metering tank 5, and the lower end of the feeder 6 is connected to the discharge pipe 8 via the main pipe of a slanted tee 7. The branch pipe of the slanted tee 7 is connected upwards to the branch duct 403, and a ball valve for adjusting the airflow is installed near the branch duct 403. The lower end of the discharge pipe 8 is connected to the feeding nozzle 9 via a union joint. Thus, the feeder 6 is responsible for delivering the feed from the metering tank 5 into the discharge pipe 8, achieving feed spraying.

[0041] In this embodiment, the oblique tee can be a 45° oblique tee.

[0042] In this embodiment, the feeding nozzles 9 are distributed on the walls of each aquaculture pond 10, and include adjustable direction nozzles, Y-type connectors, and rotary joints.

[0043] The feeder 6 includes a feeding motor and a rotating drum. The feeding motor drives the rotating drum, and the rotating drum causes the feed inside the feeder 6 to rotate and be fed into the main pipe of the inclined tee 7. The automatic feeding unit is equipped with a feeding control unit, which includes at least a control box and a cable tray, a fixing frame, a PLC, electrical control components, and an embedded industrial control touch screen installed in the control box. The feeding control unit mainly controls the total amount of feed and the feeding time.

[0044] The workflow of this system includes three processes:

[0045] Feeding process: The bait is sucked into the feed bin 1 by the automatic feeding unit. The feeding process ends when the feed bin 1 is full.

[0046] Material conveying process: The material conveying control unit controls the operation of the feed line. During the operation of the feed line, the bait in the hopper 1 is continuously fed into the feed line pipe by the feeding auger 2. As the feeding auger 2 continuously feeds the bait into the feed line, the feed line is filled with bait and transported to the workshop by the chain. A discharge port is opened in the feed line pipe above the metering hopper 5. After passing through the first metering hopper 5, the bait falls into the metering hopper 5. Once the first metering hopper 5 is full, it is transported to the second metering hopper 5. When all metering hoppers 5 are full of bait, the control unit stops the feed line operation, and the material conveying process ends.

[0047] Feeding process: The feeding control unit sets the feeding time. When the time is up, the feeding control unit starts the fan and sends the air pressure to the end air pressure detection device 404 through the air supply pipe to detect the air pressure. If there is no air pressure alarm, the control unit starts the feeder 6. The feeding motor in the feeder 6 drives the drum at the bottom of the metering bucket 5 to work. The feed in the metering bucket 5 is slowly fed into the discharge pipe 8 by the drum. The discharge pipe 8 is connected to the branch air pipe 403. The air in the air supply pipe will continuously blow the feed falling from the metering bucket 5 from the discharge pipe 8 to the feeding nozzle 9 to achieve uniform feeding. When the set feeding amount is reached, the feeding control unit will control the feeder 6 and the fan 401 to stop working, and the feeding process ends.

[0048] Throughout the entire material feeding and conveying process, the operator only needs to select operations on the industrial control touchscreen of the control unit to achieve fully automatic feeding. The automatic feeding control unit is independent of the material conveying control unit, which improves the accuracy of automatic feeding.
