Description

Technical Field

[0001] This invention belongs to the technical field of pig farm feeding equipment, specifically relating to an intelligent feeding device and feeding method. Background Technology

[0002] The existing document CN210054230U provides an automatic feeder for livestock, including a frame, a dry feed liquefaction treatment device, a limiting probe device, a water delivery pipe, a feed trough, and a control system. The dry feed liquefaction treatment device is vertically mounted on the frame. The control system, the water delivery pipe, and the limiting probe device are respectively installed on one side of the frame. The dry feed liquefaction treatment device is electrically connected to the control system. The dry feed liquefaction treatment device has an inlet at the top and an outlet at the bottom. The feed trough is located at the bottom of the frame below the outlet. One end of the water delivery pipe is connected to a water supply pipe through a solenoid valve, and the other end is connected to the dry feed liquefaction treatment device. The solenoid valve is connected to the control system. The limiting probe device is vertically mounted above the feed trough. The bottom end of the limiting probe device extends into the top of the feed trough and maintains a certain distance from the bottom wall of the feed trough. The top end of the limiting probe device is connected to the control system through a signal line. Although the aforementioned automatic feeder can achieve automatic feeding, the feed it dispenses during use is not a true liquid feed, and it cannot dispense porridge-like feed. Furthermore, the dispensed feed is not convenient for livestock to eat.

[0003] More importantly, the aforementioned automatic feeder cannot place feed only in localized feeding areas, making it unsuitable for livestock to feed at fixed locations. Summary of the Invention

[0004] At least in response to the technical problems mentioned in the background section, the present invention aims to provide an intelligent feeding device and feeding method.

[0005] The present invention adopts the following technical solution.

[0006] An intelligent feeding device includes a feed cylinder with a feeding trough below it. A spiral stirring mechanism is installed inside the feed cylinder, with its stirring shaft coaxial with the feed cylinder. Spiral stirring blades on the stirring shaft are located in a discharge channel at the bottom of the feed cylinder. A mixing chamber is located below the discharge channel, and an annular discharge port is provided along the side wall of the mixing chamber. A stirring assembly is installed inside the mixing chamber, sharing a stirring shaft and a servo drive motor with the spiral stirring mechanism. The servo drive motor is controlled by a controller. When the servo drive motor is running, the spiral stirring mechanism squeezes the feed in the feed cylinder into the mixing chamber, and the stirring assembly radially discharges the feed from the mixing chamber into the feeding trough.

[0007] Furthermore, it also includes a liquid supply system, which is controlled by a controller. The liquid supply system's liquid injection pipeline outlet is connected to the mixing chamber. The electrical control components of the liquid supply system are located on the upper side wall of the feed cylinder and are independent of the electrical control components of the spiral stirring mechanism. This design not only converts dry feed into a true liquid feed / porridge, but also ensures smooth porridge dispensing and achieves water-electricity separation, preventing water from entering the electrical control components due to problems with the water line.

[0008] As a preferred option, the cylinder is mounted on a support, and one of the lower crossbeams and one of the columns of the support are made of square tubes, with the liquid filling pipeline of the liquid supply system running through the square tubes.

[0009] To facilitate individual feeding for each pig and prevent neighboring pigs from competing for food, a circular divider is installed in the feeding trough. The circular divider divides the feeding trough into several feeding spaces that can accommodate the heads of the feeding animals. The circular divider is arranged coaxially with the feed trough.

[0010] To make it easier for pigs to eat, a cone is installed directly below the feed trough. The bottom of the cone is fixed in the feed trough and arranged coaxially with the feed trough.

[0011] As a preferred embodiment, the mixing chamber is formed by a base plate, a connecting rod, and a cylinder. The base plate and the cylinder are fixedly connected by the connecting rod. The gap between the base plate and the lower end of the cylinder serves as the annular discharge port. The base plate and the cylinder are fixedly connected to the crossbar of the support.

[0012] Furthermore, there is a gap between the upper part of the cylinder and the outer wall corresponding to the discharge channel. Several arc plates are arranged against the inner wall of the cylinder, and the number of arc plates is the same as the number of feeding spaces. All the arc plates can be used to form an annular baffle to block the annular discharge port. The distance between the outer end of the stirring blade of the stirring assembly and the inner wall of the arc plate is 5-8mm, and the gap between the bottom end of the stirring blade and the top surface of the bottom plate is no more than 2mm. An electric telescopic device is connected to the upper end of each arc plate. The electric telescopic device is installed on the outer wall of the cylinder. The telescopic rod of the electric telescopic device can move in the gap. The operation of the electric telescopic device is controlled by a controller.

[0013] A feeding method using the aforementioned intelligent feeding device, wherein the controller's storage module stores a program that can run on the processor module, and the processor module executes the program to perform at least the following steps:

[0014] S11, Read the selected feeding mode. The feeding modes include Mode 1 (feed-to-water ratio of 1:1), Mode 2 (feed-to-water ratio of 1:1.5), Mode 3 (feed-to-water ratio of 1:1.8), Mode 4 (feed-to-water ratio of 1:2), Mode 5 (custom feed-to-water ratio), Mode 6 (feed-to-water ratio of 1:0), and Mode 7 (feed-to-water ratio of 0:1). When the selected feeding mode is a custom feed-to-water ratio, the content read is the custom feed-to-water ratio.

[0015] S12, when the selected feeding mode is any one of mode one to mode five, the spiral stirring mechanism and the liquid supply system are controlled to operate synchronously and feed according to the preset parameters; when the selected feeding mode is mode six, only the spiral stirring mechanism is controlled to operate; when the selected feeding mode is mode seven, only the liquid supply system is controlled to operate.

[0016] One feeding method using the aforementioned intelligent feeding device includes a light sensor for sensing pigs installed on each electric telescopic device. The light sensor is connected to a controller, and the light emitted by the light sensor is obliquely incident on the edge of the feeding trough. The controller's storage module stores a program that can run on a processor module. When the processor module executes the program, it performs at least the following steps:

[0017] S21, during the pig feeding period, when the controller detects the pig signal sensed by the light sensor A, it controls the operation of the electric telescopic device A corresponding to the light sensor A, causing the telescopic rod of the electric telescopic device A to retract. At this time, the arc plate connected to the electric telescopic device A moves to the top of the annular discharge port; at the same time, it controls the telescopic rods of other electric telescopic devices besides the electric telescopic device A to be in the extended state, and their corresponding arc plates are located on the side of the annular discharge port.

[0018] S22, count the number of electric telescopic rods in the retracted state, and match the feed amount according to the number. The feed amount = number of pigs × feed requirement per pig per meal.

[0019] S23, Read the selected feeding mode. The feeding modes include Mode 1 (feed-to-water ratio of 1:1), Mode 2 (feed-to-water ratio of 1:1.5), Mode 3 (feed-to-water ratio of 1:1.8), Mode 4 (feed-to-water ratio of 1:2), Mode 5 (custom feed-to-water ratio), Mode 6 (feed-to-water ratio of 1:0), and Mode 7 (feed-to-water ratio of 0:1). When the selected feeding mode is a custom feed-to-water ratio, the content read is the custom feed-to-water ratio.

[0020] S24, when the selected feeding mode is any one of mode one to mode five, control the spiral stirring mechanism and the liquid supply system to operate synchronously and feed according to the preset parameters;

[0021] S25, during the set time period after the pigs finish feeding, when the controller detects that the light sensor A has not sensed the pig signal, it controls the electric telescopic device A corresponding to the light sensor A to run, so that the telescopic rod of the electric telescopic device A is reset. At this time, the arc plate connected to the electric telescopic device A moves to the side of the annular discharge port.

[0022] S26, Select Mode 7 with a material-to-water ratio of 0:1, control only the operation of the liquid supply system, and clean the residual material in the mixing chamber.

[0023] A second feeding method using the aforementioned intelligent feeding device includes installing a light sensor for sensing pigs on each electric telescopic device. The light sensor is connected to a controller, and the light emitted by the light sensor is obliquely incident on the edge of the feeding trough. The controller's storage module stores a program that can run on the processor module. When the processor module executes the program, it performs at least the following steps:

[0024] S31, During the pig feeding period, when the controller recognizes the pig signal sensed by the light sensor A, it first controls all electric telescopic devices to operate, so that the telescopic rods of all electric telescopic devices are in the extended state. At this time, all arc plates are located on the right side of the annular discharge port.

[0025] S32, count the number of light sensors A that identify pig signals, and match the feed amount according to the number. The feed amount = number of pigs × feed requirement per pig per meal;

[0026] S33, Read the selected feeding mode. The feeding modes include Mode 1 (feed-to-water ratio of 1:1), Mode 2 (feed-to-water ratio of 1:1.5), Mode 3 (feed-to-water ratio of 1:1.8), Mode 4 (feed-to-water ratio of 1:2), Mode 5 (custom feed-to-water ratio), Mode 6 (feed-to-water ratio of 1:0), and Mode 7 (feed-to-water ratio of 0:1). When the selected feeding mode is a custom feed-to-water ratio, the content read is the custom feed-to-water ratio.

[0027] S34, when the selected feeding mode is any one of mode one to mode five, control the spiral stirring mechanism and the liquid supply system to operate synchronously and feed according to the preset parameters;

[0028] S35, after the feeding continues for a set time, control the operation of the electric telescopic device A corresponding to the light sensor A, so that the telescopic rod of the electric telescopic device A retracts. At this time, the arc plate connected to the electric telescopic device A moves to the top of the annular discharge port; at the same time, the telescopic rods of other electric telescopic devices besides the electric telescopic device A are in the extended state, and their corresponding arc plates are located on the right side of the annular discharge port.

[0029] S36, execute step S35 several times until the matched feed amount is completely fed;

[0030] S37, during the set time period after the pigs finish feeding, when the controller detects that the light sensor A has not sensed the pig signal, it controls the electric telescopic device A corresponding to the light sensor A to run, so that the telescopic rod of the electric telescopic device A is reset. At this time, the arc plate connected to the electric telescopic device A moves to the side of the annular discharge port.

[0031] S38, select mode seven with a material-to-water ratio of 0:1, control only the operation of the liquid supply system, and clean the residual material in the mixing chamber.

[0032] Beneficial effects: This invention not only converts dry feed into true liquid feed / porridge, but also enables smooth porridge dispensing and separates water and electricity, preventing water from entering the electrical control system due to problems with the water line (electrical components of the water supply system). More importantly, this invention allows for flexible, smooth, and selective dispensing of porridge to specific feeding areas where only pigs are present, making it particularly suitable for pigs to feed at designated points. This not only facilitates feeding but also allows for matching different numbers of pigs. During use, when all the arc plates move above the annular discharge port, the dispensed porridge or liquid will scatter in a circular pattern into the feeding trough. When some arc plates move above the annular discharge port, the dispensed porridge or liquid will scatter in a fixed point into the feeding trough. When all the arc plates move to the side of the annular discharge port, the mixing chamber will form a storage space and a mixing space. Attached Figure Description

[0042] The technical solutions of this invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. Example

[0043] Combination Figure 1 and Figure 2 As shown, an intelligent feeding device includes a feed cylinder 1. The main body of the feed cylinder 1 is conical, and the lower section of the feed cylinder 1 is cylindrical. The feed cylinder 1 is mounted on a support 9. A feeding trough 2 is provided below the feed cylinder 1. A spiral stirring mechanism is provided inside the feed cylinder 1. The spiral stirring mechanism includes a servo drive motor, the output end of which is connected to a stirring shaft 3. The stirring shaft 3 of the spiral stirring mechanism is coaxially arranged with the feed cylinder 1. Spiral stirring blades 4 provided on the stirring shaft 3 are located in the discharge channel 5 at the bottom of the feed cylinder 1. The inner cavity of the lower section of the feed cylinder 1 is used as the feeding trough. The discharge channel 5 is described above. A mixing chamber 8 is provided below the discharge channel 5. An annular discharge port 6 is provided along the side wall of the mixing chamber 8. A stirring component 7 is provided inside the mixing chamber 8. The stirring component 7 and the spiral stirring mechanism share a stirring shaft 3 and a servo drive motor. The servo drive motor is controlled by a controller. When the servo drive motor is running, the feed in the feed cylinder 1 is squeezed into the mixing chamber 8 by the spiral stirring mechanism. The feed in the mixing chamber 8 is radially discharged and scattered into the feeding trough 2 by the operation of the stirring component 7.

[0044] The intelligent feeding device also includes a liquid supply system, which is controlled by a controller. The liquid supply system's liquid filling pipeline outlet is connected to the mixing chamber 8. The electrical control components of the liquid supply system are located on the upper side wall of the feed cylinder 1 and are independent of the electrical control components of the spiral stirring mechanism. The two sets of electrical control components are respectively installed on the top outer side wall of the feed cylinder 1 and located inside the protective cover 13. Among them, the liquid filling pipeline of the liquid supply system is equipped with a flow meter and a solenoid valve, both of which are connected to the controller. One lower crossbeam 28 and one column of the support 9 are made of square tubes, and the liquid filling pipeline of the liquid supply system passes through the square tubes.

[0045] In this embodiment, a circular divider 10 is provided in the feeding trough 2 to divide the feeding trough 2 into several feeding spaces that can accommodate the heads of feeding animals. The circular divider 10 is arranged coaxially with the feed cylinder 1. A cone 11 is provided directly below the feed cylinder 1. The bottom end of the cone 11 is fixed in the feeding trough 2 and arranged coaxially with the feed cylinder 1. The function of the cone 11 is to prevent the porridge from accumulating in the middle of the feeding trough 2.

[0046] A feeding method using the intelligent feeding device in this embodiment, wherein the storage module of the controller stores a program that can run on the processor module, and the processing module executes the program to perform at least the following steps: S11, reading the selected feeding mode, the feeding modes including mode one with a feed-to-water ratio of 1:1, mode two with a feed-to-water ratio of 1:1.5, mode three with a feed-to-water ratio of 1:1.8, mode four with a feed-to-water ratio of 1:2, mode five with other custom feed-to-water ratios, mode six with a feed-to-water ratio of 1:0, and mode seven with a feed-to-water ratio of 0:1; when the selected feeding mode is a custom feed-to-water ratio, the content read is the custom feed-to-water ratio;

[0047] S12, when the selected feeding mode is any one of mode one to mode five, the spiral stirring mechanism and the liquid supply system are controlled to operate synchronously and feed according to the preset parameters; when the selected feeding mode is mode six, only the spiral stirring mechanism is controlled to operate; when the selected feeding mode is mode seven, only the liquid supply system is controlled to operate.

[0048] In this invention, pigs are divided into six stages based on age (stage 1: 24-36 days old, stage 2: 37-56 days old, stage 3: 57-88 days old, stage 4: 57-88 days old, stage 5: 89-124 days old, and stage 6: 125-158 days old). Those skilled in the art determine the daily feed requirement for each pig based on the selected stage according to its age. Combining the aforementioned feeding pattern, the feed amount per meal / session = number of pigs × feed requirement per pig per meal ÷ 3 (based on three meals / sessions per day). For example, if the feed amount per meal / session is 20 kg, then when the feed-to-water ratio is 1:1, 10 kg of dry feed and 10 kg of water are required.

[0049] In this invention, controlling the amount of dry material added each time is a conventional technique. It can be controlled by the number of rotations of the stirring shaft 3 of the spiral stirring mechanism, or by the volume of material added, or by installing a weight sensor inside the material cylinder. These methods will not be described in detail here.

[0050] In this embodiment, not only can dry feed be converted into true liquid feed / porridge, but the porridge can also be dispensed smoothly. Furthermore, water and electricity can be separated to prevent water from entering the electrical control part due to problems with the water line (the electrical component circuit of the water supply system). During use, the dispensed porridge or liquid will be evenly scattered in the feeding trough in a circular pattern, making it convenient for each pig to eat in the feeding space. Example

[0051] Combination Figures 3 to 6 As shown, an intelligent feeding device includes a feed cylinder 1. The main body of the feed cylinder 1 is conical, and the lower section of the feed cylinder 1 is cylindrical. The feed cylinder 1 is mounted on a support 9. A feeding trough 2 is provided below the feed cylinder 1. A spiral stirring mechanism is provided inside the feed cylinder 1. The spiral stirring mechanism includes a servo drive motor, the output end of which is connected to a stirring shaft 3. The stirring shaft 3 of the spiral stirring mechanism is coaxially arranged with the feed cylinder 1. Spiral stirring blades 4 provided on the stirring shaft 3 are located in the discharge channel 5 at the bottom of the feed cylinder 1. The inner cavity of the lower section of the feed cylinder 1 is used as the feeding trough. The discharge channel 5 is described above. A mixing chamber 8 is provided below the discharge channel 5. An annular discharge port 6 is provided along the side wall of the mixing chamber 8. A stirring component 7 is provided inside the mixing chamber 8. The stirring component 7 and the spiral stirring mechanism share a stirring shaft 3 and a servo drive motor. The servo drive motor is controlled by a controller. When the servo drive motor is running, the feed in the feed cylinder 1 is squeezed into the mixing chamber 8 by the spiral stirring mechanism. The feed in the mixing chamber 8 is radially discharged and scattered into the feeding trough 2 by the operation of the stirring component 7.

[0052] The intelligent feeding device also includes a liquid supply system, which is controlled by a controller. The liquid supply system's liquid filling pipeline outlet is connected to the mixing chamber 8. The electrical control components of the liquid supply system are located on the upper side wall of the feed cylinder 1 and are independent of the electrical control components of the spiral stirring mechanism. The liquid supply system's liquid filling pipeline is equipped with a flow meter and a solenoid valve, both of which are connected to the controller. One lower crossbeam 28 and one column of the support 9 are made of square tubing, and the liquid supply system's liquid filling pipeline passes through these square tubing.

[0053] In this embodiment, a circular divider 10 is provided in the feeding trough 2 to divide the feeding trough 2 into several feeding spaces that can accommodate the heads of feeding animals. The circular divider 10 is arranged coaxially with the feed cylinder 1. A cone 11 is provided directly below the feed cylinder 1. The bottom end of the cone 11 is fixed in the feeding trough 2 and arranged coaxially with the feed cylinder 1. The function of the cone 11 is to prevent the porridge from accumulating in the middle of the feeding trough 2.

[0054] In this embodiment, the mixing chamber 8 is formed by the base plate 20, the connecting rod 21 and the cylinder 22. The base plate 20 and the cylinder 22 are fixedly connected by the connecting rod 21. The gap between the lower ends of the base plate 20 and the cylinder 22 serves as the annular discharge port 6. The base plate 20 and the cylinder 22 are fixedly connected to the crossbar 23 of the support 9. There is a gap between the upper part of the cylinder 22 and the outer wall corresponding to the discharge channel 5. Several arc plates 24 are arranged against the inner wall of the cylinder 22 (the structure schematically shows 6 arc plates 24, and the corresponding number of feeding spaces is also 6). The number of arc plates 24 is the same as the number of feeding spaces. All the arc plates 24 can be used to form an annular baffle to block the annular discharge port 6. The distance between the outer end of the stirring blade 12 of the stirring assembly 7 and the inner wall of the arc plate 24 is 5-8mm. The gap between the bottom end of the stirring blade 12 and the top surface of the bottom plate 20 is no more than 2mm. Each arc plate 24 is connected to an electric telescopic device 25. The electric telescopic device 25 is installed on the outer wall of the material cylinder 1 and is located in the protective shell 27. The telescopic rod of the electric telescopic device 25 can move in the gap and is controlled by the controller. Each electric telescopic device 25 is equipped with a light sensor 26 for sensing pigs. The light sensor 26 is connected to the controller, and the light emitted by the light sensor 26 is obliquely incident on the outer edge of the feed trough 2.

[0055] A feeding method using the intelligent feeding device in this embodiment, wherein the storage module of the controller of the intelligent feeding device stores a program that can run on the processor module, and the processor module executes the program to perform at least the following steps:

[0056] In the initial state, such as Figure 8 As shown, the telescopic rod of the electric telescopic device 25 extends downwards, and the arc plate 24 connected to the electric telescopic device 25 is in the lower limit state, that is, the annular discharge port 6 is closed at this time.

[0057] S21, during the pig feeding period, when the controller detects the pig signal sensed by the light sensor A, it controls the operation of the electric telescopic device A251 corresponding to the light sensor A, causing the telescopic rod of the electric telescopic device A251 to retract. At this time, the arc plate 24 connected to the electric telescopic device A251 moves above the annular discharge port 6; simultaneously, it controls the telescopic rods of other electric telescopic devices besides the electric telescopic device A251 to be in the extended state, with their corresponding arc plates 24 located directly to the side of the annular discharge port 6; as... Figure 7As shown, the arc plate 24 connected to the electric telescopic device A251 (two electric telescopic devices) moves to the top of the annular discharge port 6, and the arc plates 24 connected to the other four electric telescopic devices are located on the side of the annular discharge port 6. In this state, the annular discharge port 6 is only opened to 1 / 3 of its area. In this embodiment, the optical sensor A represents one or more. For example, when a pig's head approaches or extends into the feeding trough, only one optical sensor A senses the pig's signal. When two pigs' heads approach or extend into the feeding trough, two optical sensors A sense the pig's signal respectively.

[0058] S22, count the number of electric telescopic rods in the retracted state, and match the feed amount according to the number. The feed amount = number of pigs × feed requirement per pig per meal.

[0059] S23, Read the selected feeding mode. The feeding modes include Mode 1 (feed-to-water ratio of 1:1), Mode 2 (feed-to-water ratio of 1:1.5), Mode 3 (feed-to-water ratio of 1:1.8), Mode 4 (feed-to-water ratio of 1:2), Mode 5 (custom feed-to-water ratio), Mode 6 (feed-to-water ratio of 1:0), and Mode 7 (feed-to-water ratio of 0:1). When the selected feeding mode is a custom feed-to-water ratio, the content read is the custom feed-to-water ratio.

[0060] S24, when the selected feeding mode is any one of mode one to mode five, control the spiral stirring mechanism and the liquid supply system to operate synchronously and feed according to the preset parameters;

[0061] S25, during the set time period after the pigs finish feeding, when the controller detects that the light sensor A has not sensed the pig signal, it controls the electric telescopic device A251 corresponding to the light sensor A to run, so that the telescopic rod of the electric telescopic device A251 is reset. At this time, the arc plate 24 connected to the electric telescopic device A251 moves to the side of the annular discharge port 6.

[0062] S26, Select mode seven with a material-to-water ratio of 0:1, control only the operation of the liquid supply system, and clean the residual material in the mixing chamber 8.

[0063] In this embodiment, when feeding, the number of pigs that need to eat is first sensed, and then the corresponding number of arc plates 24 are controlled to move above the annular discharge port 6. Dry feed is added while water is supplied and stirred, and porridge is added locally through the annular discharge port 6. Example

[0064] A feeding method using the intelligent feeding device of Embodiment 3, wherein the storage module of the controller of the intelligent feeding device stores a program that can run on the processor module, and the processor module executes the program to perform at least the following steps:

[0065] S31, during the pigs' feeding period, when the controller detects the pig signal sensed by the light sensor A, it first controls all electric telescopic devices to operate, causing the telescopic rods of all electric telescopic devices to be in the extended state. At this time, all arc plates 24 are located directly to the side of the annular discharge port 6, as shown. Figure 8 As shown, the annular discharge port 6 is closed at this time;

[0066] S32, count the number of light sensors A that identify pig signals, and match the feed amount according to the number. The feed amount = number of pigs × feed requirement per pig per meal;

[0067] S33, Read the selected feeding mode. The feeding modes include Mode 1 (feed-to-water ratio of 1:1), Mode 2 (feed-to-water ratio of 1:1.5), Mode 3 (feed-to-water ratio of 1:1.8), Mode 4 (feed-to-water ratio of 1:2), Mode 5 (custom feed-to-water ratio), Mode 6 (feed-to-water ratio of 1:0), and Mode 7 (feed-to-water ratio of 0:1). When the selected feeding mode is a custom feed-to-water ratio, the content read is the custom feed-to-water ratio.

[0068] S34, when the selected feeding mode is any one of mode one to mode five, control the spiral stirring mechanism and the liquid supply system to operate synchronously and feed according to the preset parameters;

[0069] S35, after the feeding continues for a set time, the electric telescopic device A251 corresponding to the light sensor A is activated, causing the telescopic rod of the electric telescopic device A251 to retract. At this time, the arc plate 24 connected to the electric telescopic device A251 moves above the annular discharge port 6; simultaneously, the telescopic rods of other electric telescopic devices besides the electric telescopic device A251 are in the extended state, and their corresponding arc plates 24 are located directly to the side of the annular discharge port 6, such as... Figure 7 As shown, the arc plate 24 connected to the electric telescopic device A251 (two electric telescopic devices) moves to the top of the annular discharge port 6, and the arc plates 24 connected to the other four electric telescopic devices are located on the side of the annular discharge port 6. In this state, the annular discharge port 6 is only opened to 1 / 3 of its area. In this embodiment, the optical sensor A represents one or more. For example, when a pig's head approaches or extends into the feeding trough, only one optical sensor A senses the pig's signal. When two pigs' heads approach or extend into the feeding trough, two optical sensors A sense the pig's signal respectively.

[0070] S36, execute step S35 several times until the matched feed amount is completely fed; for example, if the required amount of porridge (matched feed amount) for a single feeding is 30kg, but each execution of step S35 can only feed 10kg, then S35 needs to be executed three times.

[0071] S37, during the set time period after the pigs finish feeding, when the controller detects that the light sensor A has not sensed the pig signal, it controls the electric telescopic device A251 corresponding to the light sensor A to run, so that the telescopic rod of the electric telescopic device A251 is reset. At this time, the arc plate 24 connected to the electric telescopic device A251 moves to the side of the annular discharge port 6.

[0072] S38, select mode seven with a material-to-water ratio of 0:1, control only the operation of the liquid supply system, and clean the residual material in the mixing chamber 8.

[0073] The main difference between this embodiment and embodiment 2 is that when feeding, the number of pigs that need to eat is sensed first, then all the arc plates 24 are moved to the side of the annular discharge port 6, then dry feed and water are added and stirred in the mixing chamber 8, then the annular discharge port 6 corresponding to the location of the pig is opened (that is, the arc plate 24 at that location is moved upward), and finally the porridge is partially added through the annular discharge port 6.

[0074] This invention not only converts dry feed into a true liquid feed / porridge, but also enables smooth porridge dispensing and separates water and electricity, preventing water from entering the electrical control system due to problems with the water line (the electrical components of the water supply system). More importantly, the solutions in Embodiments 2 and 3 allow for flexible, smooth, and selective dispensing of porridge to specific feeding areas where only pigs are present, making it particularly suitable for pigs to feed at designated locations. This not only facilitates feeding but also allows for matching different numbers of pigs. During use, when all the arc plates move above the annular discharge port (the state at this time is as follows...), Figure 9 As shown), the added porridge or liquid will be scattered into the feeding trough in a circular pattern; when some of the arc plates move above the annular discharge port, the added porridge or liquid will be scattered into the feeding trough at a fixed point; when all the arc plates move to the side of the annular discharge port, the mixing chamber will form a storage space and a stirring space.
