Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a feeding device and its control system for aquaculture. Background Technology

[0002] For land-based recirculating aquaculture systems, commercially available feeding systems generally employ time-based control, meaning feeding is done by controlling the frequency of feeding. This method suffers from inaccurate control over the amount of feed given and a limited or no adjustable feeding rate. However, recirculating aquaculture systems require very strict control over the amount and rate of feed, sometimes only a gram or two per feeding, lasting only a few seconds, and requiring over 100 feedings per day. Traditional feeding devices struggle to meet these demands.

[0003] Therefore, in order to achieve precise feeding at fixed times and in fixed quantities, there is an urgent need to develop a feeding device that can control the feeding amount more precisely and can perform a large number of feedings per day. Utility Model Content

[0004] One objective of this invention is to overcome the shortcomings of existing technologies and provide a feeding device for aquaculture. To solve the aforementioned technical problems, this invention adopts the following technical solution:

The feeding rotor is rotatably disposed inside the housing. The first driving component is fixedly connected to the housing and drivenly connected to the feeding rotor. The outer peripheral sidewall of the feeding rotor is provided with multiple material receiving grooves. The housing is provided with an inlet and a discharge outlet arranged vertically opposite to each other. The width of the discharge outlet matches the width of a single material receiving groove. The material receiving groove is used to receive bait through the inlet and release bait through the discharge outlet.

[0008] The feeding mechanism is located below the feeding mechanism. The feeding mechanism includes a centrifugal turntable and a second driving component. The centrifugal turntable is used to receive the feed falling through the feeding port. The second driving component is connected to the centrifugal turntable and is used to drive the centrifugal turntable to rotate so that the feed on the centrifugal turntable can be put into the breeding pond under the action of centrifugal force.

[0009] In one embodiment, the feeding rotor includes a rotor body and a connecting shaft, with the connecting shaft fixedly connected to one end of the rotor body;

[0010] Multiple material troughs are set on the outer peripheral sidewall of the rotor body, and the first driving component is driven to connect with the connecting shaft.

[0011] In one embodiment, in the circumferential direction of the rotor body, any two adjacent material troughs are staggered and spaced apart from each other.

[0012] In one embodiment, the outer shell includes a first shell and a second shell, the upper end of the first shell is connected to the lower end of the barrel, the second shell is a cylindrical structure, and the lower end of the first shell is connected to the circumferential sidewall of the second shell.

[0013] The feeding rotor is rotatably disposed inside the second housing. The feeding port is opened on the top side wall of the second housing, and the feeding port is opened on the bottom side wall of the second housing.

[0014] In one embodiment, the feeding device for aquaculture also includes a connector. The upper end of the feed cylinder is provided with a first connecting ring, and the first connecting ring has a first connecting hole. The upper end of the first housing is provided with a second connecting ring, and the second connecting ring has a second connecting hole corresponding to the first connecting hole. The two ends of the connector are respectively fastened to the first connecting hole and the second connecting hole.

[0015] In one embodiment, the feeding mechanism further includes a blocking member disposed on one circumferential side of the centrifugal turntable, which is used to limit the feeding direction of the bait on the centrifugal turntable.

[0016] In one embodiment, the centrifugal turntable is provided with a plurality of spaced-apart material-pulling plates, each of which extends radially along the centrifugal turntable.

[0017] Another object of this utility model is to provide a control system for a feeding device for aquaculture as described in any of the preceding claims, comprising:

[0018] The control unit is connected to the first and second drive components and is used to control the actions of the feeding mechanism and the material feeding mechanism.

[0019] The storage unit is electrically connected to the control unit and is used to store the feeding plan.

[0020] The communication unit is electrically connected to the control unit and is used to communicate with an external host computer.

[0021] In one embodiment, the first driving component is a feeding stepper motor, and the control unit is electrically connected to the feeding stepper motor. The control unit can send a first pulse signal to the feeding stepper motor to control the rotation angle and speed of the feeding stepper motor.

[0022] In one embodiment, the second driving component is a feeding DC motor, and the control unit is electrically connected to the feeding DC motor. The control unit can send a second pulse signal to the feeding DC motor to control the speed of the feeding DC motor.

[0023] utility model

[0024] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0025] In this invention, the aquaculture feeding device includes a feed hopper, a feeding mechanism, and a dispensing mechanism. The feeding mechanism includes a housing, a feeding rotor, and a first driving component. The feeding rotor is rotatably mounted inside the housing and driven by the first driving component. Multiple feed troughs are provided on the outer peripheral sidewall of the feeding rotor. The housing has an inlet and a outlet arranged vertically opposite each other, with the width of the outlet matching the width of a single feed trough. The feed troughs receive feed through the inlet and release feed through the outlet. The rotation angle and speed of the feeding rotor can be precisely controlled by the first driving component, thereby achieving precise control of the feeding amount and speed. Therefore, this aquaculture feeding device is suitable for precise feeding in fish ponds where feeding is frequent but the amount of feed per feeding is small, fulfilling the concept of frequent, small-batch feeding, and effectively reducing ammonia nitrogen concentration in the pond, thus improving aquaculture quality.

[0026] Furthermore, the feeding mechanism includes a centrifugal turntable and a second driving component. The second driving component can drive the centrifugal turntable to rotate at high speed, so that the bait on the centrifugal turntable can be thrown out from the edge of the centrifugal turntable, thereby increasing the feeding distance and area and improving the feeding effect.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Please see Figure 1 and Figure 2As shown, the aquaculture feeding device 10 of this utility model embodiment includes a feed cylinder 100, a feeding mechanism 200, and a feeding mechanism 300. The feed cylinder 100 is used to store feed. The feeding mechanism 200 includes a housing 210, a feeding rotor 220, and a first driving member 230. The housing 210 is connected to the lower end of the feed cylinder 100. The feeding rotor 220 is rotatably disposed within the housing 210, and the first driving member 230 is fixedly connected to the housing 210 and drivenly connected to the feeding rotor 220. Multiple feed troughs 221 are provided on the outer peripheral sidewall of the feeding rotor 220. The housing 210 has an inlet 213 and a discharge port 214 arranged vertically opposite to each other. The width of the discharge port 214 matches the width of a single feed trough 221. The feed trough 221 is used to receive feed through the inlet 213 and release feed through the discharge port 214.

[0044] The feeding mechanism 300 is located below the feeding mechanism 200. The feeding mechanism 300 includes a centrifugal turntable 310 and a second driving member 320. The centrifugal turntable 310 is used to receive the feed falling through the feeding port 214. The second driving member 320 is driven to connect with the centrifugal turntable 310 and is used to drive the centrifugal turntable 310 to rotate so that the feed on the centrifugal turntable 310 can be put into the breeding pond 20 under the action of centrifugal force.

[0045] like Figure 1 and Figure 3 As shown, the barrel 100 can be a cylindrical structure with openings at both ends. In other embodiments, the cross-section of the barrel 100 can also be rectangular, elliptical, polygonal, etc.

[0046] The upper opening of the feed cylinder 100 is used for feeding bait. For example, a top cover 120 may be provided at the upper opening of the feed cylinder 100, and the top cover 120 is closable connected to the upper end of the feed cylinder 100. For instance, the top cover 120 has a disc structure, and its circumferential dimension is larger than the size of the upper opening of the feed cylinder 100. The top cover 120 can be fastened to the upper opening of the feed cylinder 100. When feeding is required, the operator can lift the top cover 120; after feeding is complete, the operator can fasten the top cover 120 back onto the upper end of the feed cylinder 100.

[0047] like Figure 3 As shown, the lower opening of the feed cylinder 100 is used to communicate with the outer shell 210 of the feeding mechanism 200 so that the bait can enter the feeding mechanism 200 for feeding.

[0048] See Figure 1 In this embodiment of the present invention, the feeding mechanism 200 is located below the feed cylinder 100 and is used to quantitatively feed the bait in the feed cylinder 100 to the feeding mechanism 300. The feeding mechanism 200 includes a housing 210, which is fixedly connected to the lower opening of the feed cylinder 100.

[0049] like Figure 2As shown, in one embodiment, the outer shell 210 includes a first shell 211 and a second shell 212, with the upper end of the first shell 211 communicating with the lower end of the feed cylinder 100. Specifically, the upper end of the first shell 211 may be provided with an opening, and the upper opening of the first shell 211 surrounds the lower opening of the feed cylinder 100. Thus, the first shell 211 can smoothly receive the bait inside the feed cylinder 100.

[0050] Furthermore, the first housing 211 is fixedly connected to the barrel 100. For example, such as Figure 1 As shown, the feeding device 10 for aquaculture also includes a connector 400, wherein the connector 400 may be a rod-shaped structure with threads at both ends.

[0051] The upper end of the material cylinder 100 is provided with a first connecting ring 110, and the first connecting ring 110 has a first connecting hole. Specifically, the first connecting ring 110 may be fixed to the outer peripheral side wall of the upper end of the material cylinder 100. The outer periphery of the first connecting ring 110 may be provided with multiple lugs, and each lug has a first connecting hole.

[0052] The upper end of the first housing 211 is provided with a second connecting ring 215, and the second connecting ring 215 is provided with a second connecting hole corresponding to the first connecting hole. Specifically, the second connecting ring 215 may be fixed to the outer peripheral side wall of the upper end of the first housing 211. The outer periphery of the second connecting ring 215 may be provided with multiple lugs, and each lug is provided with a second connecting hole.

[0053] like Figure 1 As shown, the two ends of the connector 400 are respectively fastened to the first connecting hole and the second connecting hole. Specifically, the two ends of the connector 400 can pass through the first connecting hole and the second connecting hole respectively, and then the nuts are threaded to the two ends of the connector 400 respectively, so that the first housing 211 and the barrel 100 can be relatively fixedly connected through the connector 400.

[0054] See Figure 2 and Figure 3 As shown, in this utility model, the first shell 211 can be inverted cone shape, which allows the bait to enter the second shell 212 in a more concentrated manner and effectively slows down the speed at which the bait enters the second shell 212.

[0055] like Figure 2 As shown, the second housing 212 is a cylindrical structure, and the lower end of the first housing 211 is connected to the circumferential sidewall of the second housing 212. The second housing 212 and the first housing 211 can be integrally formed. The top sidewall of the second housing 212 has an inlet 213 communicating with the first housing 211. The bottom sidewall of the second housing 212 has a discharge port 214.

[0056] See Figure 2The feeding mechanism 200 includes a feeding rotor 220, which is rotatably disposed within the second housing 212. For example, as... Figure 3 As shown, the feeding rotor 220 may include a rotor body 222 and a connecting shaft 223. The rotor body 222 has a cylindrical structure. The outer peripheral surface of the rotor body 222 is in frictional contact with the inner peripheral surface of the second housing 212.

[0057] The rotor body 222 of the feeding rotor 220 can be made of materials such as polytetrafluoroethylene and nylon to minimize its weight and reduce rotational friction.

[0058] To facilitate the installation and disassembly of the feeding rotor 220, in one embodiment, the second housing 212 is a cylindrical structure with at least one open end. For example... Figure 1 As shown, the left end of the second housing 212 can be an opening, through which the feeding rotor 220 can be installed into the second housing 212. For example, an end cap 240 is provided at the left end opening of the second housing 212, and the end cap 240 is used to open or close the opening. The end cap 240 can be fixed to the left end opening of the second housing 212 by means of threaded connection or tight engagement.

[0059] like Figure 3 As shown, multiple feed troughs 221 are disposed on the outer peripheral sidewall of the rotor body 222. When the feeding rotor 220 rotates, each feed trough 221 can move to a position opposite to the feed inlet 213 to receive feed. Furthermore, each feed trough 221 can also move to a position opposite to the discharge inlet 214, so that the feed in the feed trough 221 can fall out under the action of gravity.

[0060] like Figure 2 and Figure 3 As shown, the width of the discharge port 214 matches the width of a single material container 221. It's worth noting that the width of the discharge port 214 refers to its dimension along the rotation direction of the feeding rotor 220, and the width of the material container 221 refers to its dimension along the rotation direction of the feeding rotor 220. Specifically, the matching of the width of the discharge port 214 with the width of a single material container 221 means that the width of the discharge port 214 is slightly greater than or equal to the width of a single material container 221. Therefore, the discharge port 214 can only allow bait from the material container 221 that is completely aligned and overlapped with it to fall out.

[0061] like Figure 2 and Figure 3 As shown, the discharge port 214 can be a long strip-shaped opening, the width of which matches the width of a single material container 221, and its length can be greater than or equal to the length of a single material container 221, depending on the specific situation.

[0062] See Figure 2 In one embodiment, any two adjacent feed troughs 221 are staggered and spaced apart from each other along the circumference of the rotor body 222. In this embodiment, by staggering and spacing any two adjacent feed troughs 221 along the circumference of the rotor body 222, the feed troughs 221 and the feed inlet 214 can be aligned and overlapped one-to-one when the feeding rotor 220 rotates. That is, the feed inlet 214 can only allow feed from one feed trough 221 to fall at a time, thus meeting the need for small-volume and precise feeding.

[0063] It is understood that in other embodiments, the multiple material containers 221 may also have other distribution patterns. For example, the multiple material containers 221 may be distributed side by side and spaced apart circumferentially, and also side by side and spaced apart axially. The discharge port 214 may be aligned and coincide with more than two material containers 221 at a time, depending on the specific circumstances.

[0064] In this invention, all the feeding troughs 221 have the same volume. For example, each feeding trough 221 can hold approximately 2g of bait. Therefore, during feeding, the amount of bait can be controlled by adjusting the number of feeding troughs 221 aligned with the feeding port 214. Since the number of feeding troughs 221 aligned with the feeding port 214 is determined by the rotation angle of the feeding rotor 220, the amount of bait can be precisely controlled by adjusting the rotation angle of the feeding rotor 220.

[0065] like Figure 3 As shown, the connecting shaft 223 is located at one end of the rotor body 222. The connecting shaft 223 can be made of metal. The connecting shaft 223 is used to connect with the first driving member 230 so that it rotates under the drive of the first driving member 230, thereby causing the entire unloading rotor 220 to rotate within the second housing 212.

[0066] like Figure 1 and Figure 3 As shown, the first driving component 230 is fixedly connected to one end of the second housing 212 and is driven by the unloading rotor 220. The first driving component 230 can be a stepper motor. Stepper motors have advantages such as precise angle control and simple control methods, which facilitates precise control of the rotation of the unloading rotor 220.

[0067] like Figure 1 As shown, the stepper motor can be fixedly mounted on the right end of the second housing 212 via the base 250. Exemplarily, the right end of the second housing 212 can be an opening through which the motor shaft of the stepper motor can extend into the second housing 212 for a relatively fixed connection with the connecting shaft 223. Optionally, the motor shaft of the stepper motor can be connected to the connecting shaft 223 via a coupling.

[0068] In this embodiment, by controlling the number of rotations and the angle of the stepper motor, the rotation angle of the feeding rotor 220 can be controlled very precisely, thereby achieving precise control of the feeding amount. By controlling the rotational speed of the stepper motor, the feeding speed can be controlled, thereby achieving precise control of the bait feeding speed.

[0069] See Figure 1 As shown in the embodiment of this utility model, the feeding mechanism 300 is located below the feeding mechanism 200. It is used to receive the feed falling through the feeding port 214 and put the feed into the breeding pond 20. Specifically, the feeding mechanism 300 includes a centrifugal turntable 310, which can be mounted on a bracket 330 fixedly connected to the lower part of the outer shell 210, and the centrifugal turntable 310 and the bracket 330 are rotatably connected.

[0070] like Figure 1 As shown, the second drive component 320 is fixedly connected to the bracket 330 and driven by the centrifugal turntable 310. The second drive component 320 can be a DC motor. DC motors have advantages such as good speed regulation and high operating efficiency, thus ensuring the reliable rotation of the centrifugal turntable 310.

[0071] In this embodiment, the second driving component 320 can drive the centrifugal disc 310 to rotate at high speed, allowing the bait on the centrifugal disc 310 to be thrown out from its edge, thereby increasing the feeding distance and area. Furthermore, the second driving component 320 is a DC motor, which allows for easy adjustment of the rotation speed of the centrifugal disc 310, thus enabling on-demand adjustment of the throwing distance and improving the controllability of the feeding mechanism 300.

[0072] like Figure 3 As shown, the centrifugal disc 310 is positioned opposite the feed inlet 214 of the outer casing 210 to fully receive the bait falling through the feed inlet 214. In one embodiment, a downwardly extending hopper 216 may be provided at the feed inlet 214 of the second casing 212. The lower end of the hopper 216 may be as close as possible to the centrifugal disc 310. For example, one side wall of the hopper 216 may be inclined to concentrate the bait falling onto the centrifugal disc 310, preventing the bait from being scattered and falling outside the centrifugal disc 310.

[0073] See Figure 1In one embodiment, the centrifugal turntable 310 is provided with a plurality of spaced-apart feed-distributing plates 311, each extending radially along the centrifugal turntable 310. In this embodiment, when the centrifugal turntable 310 rotates at high speed, the plurality of feed-distributing plates 311 can disperse the falling bait on the centrifugal turntable 310 and effectively prevent the bait from accumulating and sticking together. In addition, when the centrifugal turntable 310 rotates at high speed, the bait on it will be more smoothly thrown out towards the edge of the centrifugal turntable 310 along the guidance of the feed-distributing plates 311, thereby improving the efficiency of bait throwing out.

[0074] See Figure 1 In one embodiment, the feeding mechanism 300 further includes a blocking member 340, which is used to limit the feeding direction of the feed on the centrifugal turntable 310. The blocking member 340 may be fixed to the support 330 and located on one circumferential side of the centrifugal turntable 310. For example, the blocking member 340 may be an arc-shaped plate integrally formed on the support 330. When the centrifugal turntable 310 rotates at high speed to feed the aquaculture pond 20, the blocking member 340 ensures that the feed is fed towards the aquaculture pond 20.

[0075] See Figure 4 As shown, the aquaculture feeding device of this embodiment can be fixedly installed on a frame located next to the aquaculture pond 20 during use. During feeding, the first drive component 230 and the second drive component 320 can be activated respectively. Thus, the feeding mechanism 200 can achieve quantitative and constant-speed feeding, and the feeding mechanism 300 can directionally throw the feed into the aquaculture pond 20.

[0076] See Figure 5 An embodiment of this utility model also provides a control system 30 for a feeding device for aquaculture, including a control unit 31, a storage unit 32, a communication unit 33 and a clock unit 34, as well as a backup power supply unit 35, a drive circuit 36 ​​and a power module 37.

[0077] The control unit 31 is connected to the first drive unit 230 and the second drive unit 320, and is used to control the actions of the unloading mechanism 200 and the feeding mechanism 300. For example, the control unit 31 can be a microcontroller. The microcontroller may have a watchdog timer, which can power-off and restart the microcontroller when an error occurs in the microcontroller program.

[0078] Alternatively, the control unit 31 can also be a programmable logic controller (PLC).

[0079] like Figure 5As shown, the first drive unit 230 is a feeding stepper motor, and the control unit 31 is electrically connected to the feeding stepper motor. For example, the control unit 31 can be electrically connected to the feeding stepper motor via the stepper driver 41.

[0080] The control unit 31 can send a high voltage signal or a low voltage signal to the feeding stepper motor to start or stop the feeding stepper motor.

[0081] The control unit 31 can also send a first pulse signal to the feeding stepper motor to control the rotation angle and speed of the feeding stepper motor. Specifically, the first pulse signal includes the number of pulses and the pulse frequency. The number of pulses determines the rotation angle of the feeding stepper motor, thereby controlling the rotation angle of the feeding rotor 220 and thus controlling the feeding amount. The pulse frequency determines the speed of the feeding stepper motor, thereby controlling the speed of the feeding rotor 220 and thus controlling the feeding speed.

[0082] like Figure 5 As shown, the second drive unit 320 is a feeding DC motor, and the control unit 31 is electrically connected to the feeding DC motor. The control unit 31 can be electrically connected to the feeding DC motor through a switching circuit and / or a drive circuit 36 ​​to control the feeding DC motor to start or stop operation.

[0083] Furthermore, the control unit 31 can also send a second pulse signal to the feeding DC motor to control its speed. Specifically, the feeding DC motor can have built-in pulse width modulation (PWM) functionality. When the control unit 31 sends a second pulse signal with an adjustable duty cycle to the feeding DC motor, the feeding DC motor can automatically adjust its speed, thereby enabling adjustment of the bait delivery distance and area.

[0084] like Figure 5 As shown, the storage unit 32 is electrically connected to the control unit 31 and is used to store the feeding plan. The storage unit 32 can be a hard drive, memory, smart media card (SMC), flash card, flash memory device, etc.

[0085] like Figure 5 As shown, the clock unit 34 is electrically connected to the control unit 31, and is used by the control unit 31 to read and calibrate the time. The clock unit 34 can be a clock module integrated into the microcontroller. Alternatively, the clock unit 34 can be an external clock.

[0086] Specifically, the clock unit 34 can send a clock signal to the control unit 31, enabling the control unit 31 to precisely control the feeding device to feed according to the set time interval. For example, the clock unit 34 can set the time interval for timed feeding, such as sending a clock signal to the control unit 31 every 10 minutes, so that the control unit 31 can control the aquaculture feeding device 10 to perform feeding operations at regular intervals.

[0087] In addition, the microcontroller can read the time from clock unit 34 when it is powered on and use it as the microcontroller's time. Afterward, the microcontroller can read the time from clock unit 34 at regular intervals, such as 7 hours, to ensure the accuracy of the microcontroller's clock.

[0088] like Figure 5 As shown, the control system 30 may further include a backup power supply unit 35, which is electrically connected to the clock unit 34 to supply power to the clock unit 34. The backup power supply unit 35 may be a button battery. By providing the backup power supply unit 35, power can be supplied to the clock unit 34 in the event of a power outage in the control system 30, preventing clock loss.

[0089] like Figure 5 As shown, the communication unit 33 is electrically connected to the control unit 31 and is used for communication with an external host computer. The communication unit 33 can be a wireless communication unit, such as a WIFI module, a ZigBee module, or a 4G / 5G module. Thus, the external host computer can remotely control the control system 30 and the feeding device via wireless connection.

[0090] For example, an external host computer can remotely download and upload feeding plans. The feeding plan downloaded to the microcontroller is automatically stored in storage unit 32 to prevent loss.

[0091] An external host computer can remotely calibrate the clock unit 34 and the microcontroller clock. Furthermore, the external host computer can remotely query the clock unit 34 to detect if the clock is lost.

[0092] An external host computer can remotely switch between the test mode and the automatic feeding mode of the feeding device.

[0093] An external host computer can remotely start and stop the feeding stepper motor and start, stop, and adjust the speed of the throwing DC motor.

[0094] Alternatively, in other embodiments, the communication unit 33 may also be a wired communication unit, such as optical fiber, Ethernet, etc.

[0095] like Figure 5As shown, the control system 30 may also include a power supply module 37, which is electrically connected to an external DC power supply 42. The power supply module 37 can convert the voltage of the external DC power supply 42 into the voltage required by the control system 30 and supply power to each unit component of the entire control system 30.

[0096] See Figure 4 and Figure 5 The control system 30, external DC power supply 42, and stepper driver 41 can be centrally located in an electrical box 40. The electrical box 40 can be fixedly installed on a frame located next to the aquaculture pond 20.

[0097] When the feeding device and its control system for aquaculture according to this utility model embodiment are in operation:

[0098] First, the microcontroller can obtain the feeding plan from an external host computer or from its storage unit. For example, the feeding plan can be to feed the fish pond every 10 minutes, 144 times a day, with a single feeding amount of 8g.

[0099] Then, the microcontroller can control the feeding mechanism 300 to operate at a predetermined time according to the above feeding plan. At this time, the second drive unit 320 is activated, that is, the feeding DC motor can drive the centrifugal turntable 310 to rotate.

[0100] After the feeding mechanism 300 is running, the microcontroller can control the discharging mechanism 200 to run. At this time, the first driving component 230 is activated, that is, the discharging stepper motor can drive the discharging rotor 220 to rotate. At the same time, according to the above feeding plan, the microcontroller will control the discharging stepper motor to rotate 85°, so that the discharging rotor 220 rotates by the corresponding angle, so that the number of material receiving troughs 221 discharging through the discharging port 214 is 4, that is, the amount of bait discharging is 8g.

[0101] After a single feeding cycle, the microcontroller can control the feeding mechanism 200 to stop first, and then control the feeding mechanism 300 to stop after a preset time. Because the feeding stepper motor stops first at the end of the feeding cycle, followed by the throwing DC motor, it effectively prevents unthrown bait from remaining on the centrifugal turntable 310, thus avoiding bait waste.

[0102] The aquaculture feeding device of this utility model includes a feed cylinder, a feeding mechanism, and a dispensing mechanism. The feeding mechanism includes a housing, a feeding rotor, and a first driving member. The feeding rotor is rotatably disposed within the housing and driven by the first driving member. Multiple feed troughs are provided on the outer peripheral sidewall of the feeding rotor. The housing has an inlet and a outlet arranged vertically opposite to each other, with the width of the outlet matching the width of a single feed trough. The feed troughs receive feed through the inlet and release feed through the outlet. The rotation angle and speed of the feeding rotor can be precisely controlled by the first driving member, thereby achieving precise control of the feeding amount and speed. Therefore, the aquaculture feeding device of this utility model is suitable for precise feeding in fish ponds where feeding is done frequently but in small amounts each time. It makes feeding more rational, meets the concept of small, frequent feeding, and effectively reduces the ammonia nitrogen concentration in the fish pond.

[0103] Furthermore, the feeding mechanism includes a centrifugal turntable and a second driving component. The second driving component can drive the centrifugal turntable to rotate at high speed, so that the bait on the centrifugal turntable can be thrown out from the edge of the centrifugal turntable, thereby increasing the feeding distance and area and improving the feeding effect.

[0104] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0105] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
