[0023] The present invention relates to a liquid feeder management system, which is a liquid feeder management system in which a water supply pipe is installed in a feeder installed in a pigpen to supply water together with feed. The management system is characterized in that a control unit of a controller of the feeder determines whether the water supply amount of each number of pigs exceeds a set value, and when the feed eaten by the pigs is less than the set value, the information is transmitted to the smart phone of the pig farm manager.

[0024] In addition, the invention is characterized in that the management personnel directly inputs the number of the pigs through the input device of the controller.

[0025] In addition, the control unit calculates the automatic water supply amount according to the feed supply amount differently according to seasons.

[0026] In addition, the present invention is characterized in that the calculation unit of the controller can calculate the amount of feed supplied to each feeder based on the amount of water supplied.

[0027] In addition, it is characterized in that the amount of feed supplied to each feeder is detected by a supply amount detection sensor installed in the feeder and transmitted to the control unit of the controller.

[0028] In addition, the feed amount detection sensor measures the number of revolutions of a screw conveyor or a disc conveyor that supplies feed to each feeder, which is characterized in that.

[0029] In addition, the invention is characterized in that the control unit calculates the number of revolutions by means of the calculation unit.

[0030] In addition, the present invention is characterized in that an appropriate feed supply amount for the number of pigs is set in the controller storage unit.

[0031] In addition, the invention is characterized in that, in the controller storage unit, the optimum feed supply amount is calculated by multiplying the appropriate feed supply amount by a weight according to the season.

[0032] Furthermore, the AI ​​module uses the LSTM module to predict the appropriate feed supply using a data set reflecting the appropriate feed supply in the previous period, and for this purpose, the AI ​​module machine-learned by the LSTM module is used.

[0033] In addition, the automatic water supply amount according to the feed supply amount is also calculated differently according to the season.

[0034] In addition, the optimum feed supply amount is calculated by changing the appropriate feed supply amount according to the weight or age of the pig and multiplying the appropriate feed supply amount by the weight of the calculated age value.

[0035] In addition, it is characterized in that the number of pigs is automatically input by artificial intelligence calculating the number of pigs based on the screen captured by CCTV.

[0036] In addition, AI calculates the number of pigs in each pigpen based on images of pigs learned through machine learning.

[0037] The feature of the method is that the image is processed by the OPENCV module.

[0038] Machine learning is performed by the YOLO module or the PyTorch module, and the processed image is input into the control unit after passing through the YOLO module or the PyTorch module.

[0039] In addition, the feature is that the main controller is installed in the pig pen or the management room, and performs wired and wireless communication with the respective feeder controllers to monitor the status of the respective feeders.

[0040] In addition, it is characterized in that the main control unit transmits the data of the individual feeders to the remote server of the management company, and the server control unit monitors the individual feeders, and when the pigs eat less feed than the set value, the message is transmitted to the smart phone of the pig farm manager.

[0041] The present invention is described in detail below with reference to the accompanying drawings.

[0042] The present invention is a liquid feeder management system that installs a water supply pipe in a feeder installed in a pig pen of a pig farm to supply water together with feed. The control unit of the feeder controller determines whether the water supply of each pig exceeds a set value. When the feed intake of the pig is lower than the set value, an alarm is generated or an alarm is sent to the smart phone of the pig farm manager.

[0043] The control unit can calculate the automatic water supply amount according to the feed supply amount differently according to the season. It is calculated by multiplying the weighted.

[0044] The controller's calculation unit calculates the amount of feed to be supplied to each feeder based on the amount of water supplied. The amount of water supplied can be measured by checking the opening time of the solenoid valve.

[0045] Another method is that a supply amount detection sensor measures the number of revolutions of a screw or disc conveyor that supplies feed to each feeder and transmits the information to a control unit of a controller.

[0046] The control unit calculates the number of rotations as the rotation amount by the calculation unit.

[0047] The appropriate feed supply amount for the number of pigs is set in the controller storage unit. And in the controller storage unit, the optimized feed supply amount is calculated by multiplying the appropriate feed supply amount by the weight of the season. At the same time, the appropriate feed supply amount can be set according to the weight of the whole pig. Since the pigs are usually placed in a pigpen with similar ages, the total weight of the pigs is calculated by multiplying the standard weight of the age by the number of pigs.

[0048] The administrator directly inputs the number of pigs through the input device of the controller or automatically counts and stores it in the storage unit. Automatic counting uses a CCTV camera and an AI module. The AI ​​module uses an LSTM module to predict the appropriate feed supply using a data set that reflects the appropriate amount of feed in a certain period of time before. For this purpose, an AI module that uses machine learning through an LSTM module is used.

[0049] The automatic water supply amount according to the feed supply amount is also calculated differently according to the season.

[0050] The optimal feed supply is calculated by changing the appropriate feed supply according to the age of the pig and multiplying the appropriate feed supply by the weight of the calculated age value.

[0051] The number of pigs is automatically entered by artificial intelligence counting the number of pigs based on screens captured by CCTV.

[0052] AI calculates the number of pigs in each pigpen based on the pig images learned through machine learning. The images are processed by the OPENCV module and then input into the AI ​​module.

[0053] Machine learning is performed by the YOLO module or the PyTorch module, and the processed image is input into the control unit after passing through the YOLO module or the PyTorch module.

[0054] The main controller is installed in the pig pen or management room, and communicates with the individual feeder controllers via wired and wireless communications to monitor the status of the individual feeders.

[0055] The main control unit transmits the data of the individual feeders to the remote server of the management company. The server control unit monitors the individual feeders and transmits the data to the smartphone of the pig farm manager when the pigs' feed intake falls below the set range.

[0056] The present invention increases the water supply in summer by changing the set value according to the season. The higher the temperature, the more water is supplied, but it is limited not to exceed the set value.

[0057] There are about 50 pigs in the pig pen, and one feeder is installed. Each feeder is equipped with a water supply pipe so that it can supply water when feeding feed.

[0058] The structure of the feeder of the present invention is described as follows.

[0059] The present invention is a method for pigs to eat feed mixed with water very quickly, thereby ingesting a large amount of feed in a short period of time.

[0060] In order for the pig to take feed from the feeder, the pig must touch the feed discharge portion of the feeder. This causes the feed to come out, and at this point, a sensor detects the movement of the discharge portion and uses an electrical signal to open and close the solenoid valve.

[0061] It is very important to supply water in proportion to the amount of feed discharged. This is controlled by the control unit. When the discharge part is touched once, water will come out once, and no matter how many times the discharge part is touched, after a predetermined time,

[0062] The water is discharged again. By properly balancing the feed and water mixture by how much water should be discharged at a time and how to make it come out little by little each time it contacts the discharge part, the pigs can eat the feed more easily and take in a large amount of feed in a short period of time.

[0063] The sensor may be mounted at the upper portion or at the lower portion, and when mounted at the upper portion, an existing motion detection sensor is used, and when mounted at the lower portion, an existing contact sensor is used.

[0064] First, the case of installation at the lower part is described. In the present invention, the water supply pipe is installed at the feed supply part of the feeder, and the feed of the feeder is supplied from the upper part.

[0065] A sensor is installed at the mounting part of the feed discharge part at the lower part of the hopper, so that when the pig pushes the feed discharge part, the feed discharge part contacts the side of the sensor. When the sensor sends a signal to the controller, the control unit opens the water supply pipe electric valve to supply water.

[0066] The lower part of the hopper is divided into an inner hopper and an outer hopper. A feed discharge part is installed on the outer surface of the inner hopper or the inner surface of the outer hopper. The upper end of the feed discharge part is inserted between the outer surface of the inner hopper and the inner surface of the outer hopper. The upper end of the feed discharge part is installed so that there is a gap between the outer surface of the inner hopper and the inner surface of the outer hopper, so that when the pig contacts or rotates the feed discharge part, the upper part of the feed discharge part is detected by the sensors installed on the outer surface of the inner hopper and the inner surface of the outer hopper.

[0067] The inner hopper is inclined so that the lower diameter is smaller than the upper diameter, and the outer hopper is manufactured in a vertical shape.

[0068] A bracket is connected to the lower part of the feed discharge part, and a support rod is vertically connected to the bracket. The upper end of the support rod is connected to the upper part of the hopper through a nut. The length of the support rod is adjusted by pulling it up and down, and it is fixed by tightening the nut. Not only can the feed supply be adjusted, but the inner hopper is inclined so that the lower diameter is smaller than the upper diameter, and the outer hopper is manufactured in a vertical shape, so the length of the support rod can be adjusted by pulling it up and down.

[0069] At this time, the feed amount is adjusted by adjusting the contact distance between the sensor and the upper part of the feed discharge part.

[0070] The hopper and the feed discharge part are made of metal, in particular stainless steel.

[0071] When the sensor is installed at the bottom of the present invention, the sensor used is an existing contact sensor, and an optical sensor or a magnetic sensor can also be used.

[0072] The support is in the shape of a round rod and is combined with a ring. The ring passes through and supports the inner wall of the feed discharge part. The support rod passes through the center of the support up and down and is combined with the upper and lower nuts.

[0073] In particular, the water supply pipe is installed on the side wall of the feeder so as not to interfere with the feeding of the feed. Alternatively, the water supply pipe is installed on the grille of the feeder so as not to interfere with the feeding.

[0074] In addition, the feed plate is composed of a central protrusion located at the lower part of the hopper and a feed supply part surrounding the protrusion to accommodate the feed.

[0075] The convex portion is composed of an upper flat portion, a first inclined portion connected to the flat portion and having a gentle downward slope, and a second inclined portion that continues steeply from the first inclined portion.

[0076] To explain the feed supply of the hopper, when the pig ingests the feed, the feed discharge part moves by contacting the feed discharge part, and the feed in the hopper is discharged smoothly without agglomeration due to its own weight and impact.

[0077] The lower part of the support rod is horizontally connected to a round rod-shaped bracket rotating around the support rod, and arc-shaped rings are fixed at both ends of the bracket. The two ends of the ring are installed to penetrate the wall of the feed discharge part. When the pig contacts the ring of the feed discharge part, the feed discharge part rotates around the center of the fixed support rod. On the other hand, the support rod and the bracket can be integrated, so that when the iron sheet rotates, the support rod also rotates.

[0078] On the other hand, in the present invention, when the sensor is installed at the upper part, an existing motion detection sensor is used, and the motion detection sensor is installed at the upper part of the support rod. When the support rod rotates, the motion detection sensor installed around it detects it and sends a signal to the control unit, and the control unit opens the electric valve of the water supply pipeline to supply water, and the water and feed mixed feed is supplied to the feed plate 100, so that the pigs can ingest the feed mixed with water. Therefore, in the present invention, the speed at which the pigs eat the feed mixed with water is very fast, so a large amount of feed can be ingested in a short time, and no residue will remain in the feeder, which has a significant cleaning effect.

[0079] Specifically, the upper sensor of the present invention adopts a motion detection sensor and is installed at an angle on the upper part of the feeder.

[0080] If the sensor is installed on the outlet side of the lower part of the feeder, a lot of labor is required to assemble it, and once a failure occurs, the entire device must be disassembled and reassembled, which is very inconvenient.

[0081] However, when the length between the lower and upper parts of the outlet is long and the inside of the hopper for charging the feed is full of feed, power cannot be properly transmitted to the upper part due to the resistance of being buried (trapped) in the feed, making it difficult to capture the movement of the sensor detecting the movement of the upper part.

[0082] When installed at the upper end, it is not only easy to assemble, but also easy to repair in case of failure.

[0083] However, there is still a part where the distance of motion capture is reduced as the lower outlet movement, so in order to make it accurate, the center axis connected from bottom to top is bolted from left to right at the center of the intersection with the upper end of the hopper so that it does not deviate from the upper and lower parts, and the hole through which the center axis passes is slightly enlarged to leave space, so that the force of the feed port movement from below can be fully felt from above. Then, the support rod as the center axis can move slightly but freely.

[0084] The upper part of the support rod as the central axis adopts an elastic spring. Even if the central axis moves slightly, the spring moves greatly. Therefore, if a slightly heavier object is placed on the spring, the spring will shake more. At this time, when the spring and the object placed on it shake violently, the sensor can easily capture the movement of the feed port from the top.

[0085] Meanwhile, in the present invention, the protection tube may be concentrically mounted on the outer circumference of the support rod with a gap in the radial direction.

[0086] In another embodiment, the upper end of the support rod is connected to one end of the lever, and the motion detection sensor detects the movement of the other end of the lever, so that the hinge point of the lever, that is, the center of rotation is close to the support rod, and the movement of the upper part is amplified at the other end of the lever, making it easier for the motion detection sensor to detect the movement.

[0087] As another embodiment of the structure of the liquid feeder of the present invention, Fig. 9 A view of a lower feed anti-jamming device of another embodiment of a liquid feeder of the present invention, Fig.10 is a perspective view of a liquid feeder equipped with the lower feed anti-stagnation device of the present invention, Fig.11 This is a photo of a liquid feeder equipped with a lower feed anti-stuck device.

[0088] The lower part of the hopper is divided into an inner hopper and an outer hopper. A feed discharge part is installed on the outer surface of the inner hopper or the inner surface of the outer hopper. The upper end of the feed discharge part is inserted between the outer surface of the inner hopper and the inner surface of the outer hopper. The upper part of the feed discharge part is installed with a gap between the outer surface of the inner hopper and the inner surface of the outer hopper, so that when the pig contacts or rotates the feed discharge part, the upper part of the feed discharge part contacts the outer surface of the inner hopper or the inner surface of the outer hopper.

[0089] The inner hopper is inclined such that the lower diameter is smaller than the upper diameter, and the outer hopper is manufactured in a vertical shape.

[0090] The hopper and the feed discharge part are made of metal, especially stainless steel.

[0091] The feed plate is composed of a convex portion located at the center of the lower part of the hopper and a feed supply portion surrounding the convex portion and containing feed.

[0092] The convex portion is composed of an upper flat portion, a first inclined portion continuous with the flat portion and having a gentle slope toward a lower portion, and a second inclined portion that is steeply continuous from the first inclined portion.

[0093] In particular, the water supply pipe is mounted on the side wall of the feeder so as not to interfere with the ingestion of feed.

[0094] To explain the feed supply of the hopper, when the pig ingests the feed, the feed discharge part is moved by contacting the feed discharge part, and the feed placed in the hopper does not clump due to its own weight and impact, and the feed accumulated in the hopper is discharged smoothly.

[0095] In the present invention, the feed control cylinder 900 is installed inside the feed discharge part 20, and the upper periphery of the feed control cylinder 900 is fixed to the inner wall of the feed discharge part 20, and the two ends of the support rod are fixed on the inner wall of the feed control cylinder 900. As the support rod moves up and down, the support rod 40, the feed control cylinder 900 and the feed discharge part 20 move together.

[0096] When the support rod 40 is facing downward, the lower surface of the feed control cylinder 900 is in close contact with the upper rotating plate 810 of the rotating device 800, so that the feed discharged from the feed discharge part cannot pass through the feed control cylinder 90 and be discharged to the external supply plate, and when the support rod 40 is facing upward, the lower surface of the feed control cylinder 900 is separated from the upper rotating plate of the rotating device to form a gap, and the feed from the feed discharge part is discharged to the external supply plate through the feed control cylinder 900 through the gap.

[0097] The rotating device 800 is composed of an upper rotating plate 810 and arc-shaped rings 820 radially formed at predetermined intervals on the periphery of the rotating plate 810, a support rod is connected to a hole formed in the center of the rotating plate, and the rotating plate is connected to freely rotate around the support rod, and the lower surface of the rotating plate 810 contacts the upper surface of the protrusion 110 protrudingly formed in the center of the feed plate 100. Therefore, when the pig contacts the ring 820 of the rotating device 80, the rotating plate 810 rotates around the support rod 40 to discharge the feed stagnant between the lower side of the feed control cylinder 90 and the rotating plate 810 to the feed supply plate 100. The rotating plate has a disc shape.

[0098] The middle part of the horizontal rod is connected to the upper end of the support rod 40, and one end of the horizontal rod is fixed by a hinge. When the user holds and presses the other end, the support rod moves downward, and when the user holds and lifts the other end, the support rod moves upward. Alternatively, as shown in the figure, the user can move the support rod up and down by turning the handle 301 left and right.

[0099] The present invention relates to a liquid feeder (water and feed mixed) for pig farming, which aims to provide fine and accurate control of feed quantity, allowing pigs to smoothly operate the feed discharge part with less force, thereby easily discharging feed and increasing feed intake. However, the existing method is that if the pig uses the digging habit (the habit of digging the ground) to set the ring at an angle of about 45 degrees on the outside, when the pig lifts up with its nose, the connected discs will rotate together and the feed will come out.

[0100] In the prior art, the feed discharge pipe is filled with feed, and the feed directly contacts the lower part of the feed plate, and the entire load loaded in the hopper and the friction between the floor and the inner wall of the pipe will hit the outlet, which is particularly difficult for young pigs to discharge normally due to their lack of physical strength.

[0101] When the pigs access the outlet and the tube is full of feed, discharging the feed onto the disc will significantly reduce the load, even if it is difficult.

[0102] When the ring rotates, the upper part of the cone, which serves as a blind spot, scrapes feed, dust, etc., and rotates, so there is no need to clean it deliberately, and it can be managed hygienically.

[0103] The reason for reducing the size of the last outlet is that by reducing the size of the outlet, the volume can be fine-tuned.

[0104] The outer ring is tilted at an angle of about 45 degrees, so when the pig uses its digging behavior to push the rod from the bottom with its nose, the disc connected to the ring will turn due to the angle.

[0105] For young pigs, they are good at pushing upwards by digging behavior, but they do not realize that rotation will cause feed to come out. Therefore, by tilting the arcuate ring of the present invention at an angle of about 45 degrees, rotating while easily pushing upwards by digging behavior, sufficient feed can be smoothly provided to piglets.

[0106] Even for large pigs, if the excretion part moves easily and smoothly, the excretion volume will increase and the feed intake will also increase.

[0107] In the hot summer, when the pig shakes off some water on the floor (because of the heat), the water will splash onto the discharge part where the feed comes out, making the feed wet. The wet feed blocks the feed discharge, causing great inconvenience. The present invention is a means to solve this problem and an improved invention. The discharge port becomes smooth and labor-saving, and the problem that the feed cannot be discharged due to being wet by water is also solved.

[0108] In the present invention, the pigs rotate the ring, the feed comes out, and water is supplied through the sensor. The amount of water supplied is determined according to the number of pigs and stored in the storage part of the controller. The water supply is controlled by controlling the opening time of the solenoid valve.

[0109] Therefore, the present invention has the remarkable effect of being able to judge whether the pigs have taken an appropriate amount of feed and water according to the feeding conditions such as the number of pigs in the pigsty, and being able to quickly and accurately manage the health status of the pigs by judging abnormal conditions in advance.
