Description

Technical Field

[0001] This invention relates to the field of livestock breeding technology, specifically to an intelligent feeding system and method for livestock farms. Background Technology

[0002] Pig farming is an agricultural activity that involves artificially raising pigs to obtain pork, pigskin, and other products. It encompasses the entire chain from breeding and reproduction to feeding management, disease control, and sales. Modern pig farming often adopts large-scale, intensive models, emphasizing scientific management. It improves growth efficiency through precise feed formulation, maintains suitable temperature and humidity using environmental control systems, and implements strict disease prevention procedures. Current farm feeding systems precisely deliver mixed and processed feed to troughs through pipelines and dynamically adjust the feed amount based on the pig's weight. This system achieves automated and precise feeding, reduces human intervention, avoids feed waste, and ensures balanced nutrition for pigs, thereby improving farming efficiency and economic benefits. It is one of the key technologies in modern pig farming.

[0003] However, the feeding troughs in the pigsty are mostly ineffective in preventing pigs from fighting over food. Even if the feed is given according to the pigs' weight, the fighting over food will cause changes in the amount of feed the pigs eat, which will affect their growth. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent feeding system and method for livestock farms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent feeding system for a livestock farm, comprising side fences and feeding troughs, wherein the number of side fences is two sets and they are respectively arranged on both sides of the feeding troughs, and further comprising: A fixed platform is positioned between the two side rails, with one side of the fixed platform being designed to be inclined. A support platform is located on one side of the fixed platform, and its width is the same as that of the fixed platform; A hydraulic triggering mechanism is disposed below the support platform and provides support for the support platform during its vertical movement. The hydraulic triggering mechanism provides support to the support platform using elastic force. Two sets of revolving doors are arranged on both sides above the inclined surface of the fixed platform. The surface of the revolving door is welded with a rotating rod, and the rotating rod and the side rail are fixed to each other through bearing seats to enable the revolving door to rotate. The surface of the revolving door is fixedly connected with a rollable elastic fabric, and the surface of the side rail is also provided with a pressure sensor. A hydraulic control mechanism uses the hydraulic power of the hydraulic triggering mechanism to control the opening and closing of the revolving door; A feeding mechanism is used to feed the inside of the feeding trough. The feeding mechanism consists of a feeding pipe, a flow meter, and a solenoid valve. An optical weighing probe is positioned between the two side rails, and a fixing rod is bolted to the top of the side rails, which is then bolted to the optical weighing probe to secure it.

[0006] Preferably, the hydraulic triggering mechanism includes: A base is located below the support platform; An elastic element, the top of which is in contact with the top of the support platform; Two sets of hydraulic push-pull assemblies are located on opposite sides of the top of the base, and the hydraulic push-pull assemblies are connected to the hydraulic control mechanism. The sliding trigger assembly consists of four sets, located at the four corners of the top of the base. Vertical columns are bolted to the four corners of the bottom of the support platform, and the sliding trigger assembly is in contact with the vertical columns.

[0007] Preferably, the hydraulic push-pull assembly includes: The first cylinder is bolted to the top of the first cylinder; The support plate is bolted to the periphery of the first cylinder and has a ring-shaped design. The elastic element is a compression spring and its upper and lower ends are in contact with the support platform and the support plate, respectively. The first movable column is bolted to the bottom of the support platform; The first piston is movably connected to the inner wall of the first cylinder, and the first piston and the first movable column are fixed to each other.

[0008] Preferably, the sliding trigger assembly consists of a sliding sleeve, a connecting rod, and an infrared sensor. The bottom end of the connecting rod is bolted to the base, and the other end of the connecting rod is welded to the sliding sleeve. The vertical column is in contact with the inner wall of the sliding sleeve and is slidably connected. The infrared sensor is disposed through the surface of the connecting rod.

[0009] Preferably, the hydraulic control mechanism includes: The second cylinder is located above the side rail. The top of the side rail is bolted to a shell, and the second cylinder is fixed inside the shell. The second cylinder is connected to the first cylinder. The second piston is slidably connected to the inner wall of the second cylinder; The second movable column is fixed to the second piston; The connecting plate is bolted to the end of the second movable column furthest from the second piston. The rack has a double-sided toothed design and is bolted to the connecting plate. The teeth on one side of the rack are connected to the rotating rod through gear transmission. The transmission rod is rotatably connected to the inner wall of the housing, and the transmission rod is connected to the teeth on the other side of the rack via gear transmission; The winding and unwinding assembly winds up or unwinds the elastic fabric in accordance with the opening and closing of the revolving door.

[0010] Preferably, a first connecting pipe and a second connecting pipe are respectively connected to the surface of the first cylinder, and the other ends of the first connecting pipe and the second connecting pipe are respectively connected to the two sides of the second cylinder.

[0011] Preferably, the retractable assembly consists of a long rod and a limiting plate. A cover is also bolted to the side of the side rail. The long rod passes through the cover and the housing and is rotatably connected to the point of penetration. The long rod is connected to the transmission rod through gear transmission. One end of the elastic fabric is fixed to the long rod. There are two sets of limiting plates, which are respectively bolted to the upper and lower sides of the surface of the long rod.

[0012] Preferably, the surface of the side rail is further provided with an auxiliary guide assembly, which consists of a vertical groove, a first auxiliary roller, a second auxiliary roller, and a cleaning component. The vertical groove is formed on the surface of the side rail and communicates with the interior of the cover. The first auxiliary roller is rotatably connected to the inner wall of the vertical groove. The first auxiliary roller is arranged in two rows. The second auxiliary roller is fixed to the side rail by a bearing seat so that it can rotate. The elastic fabric is in contact with the first auxiliary roller and the second auxiliary roller respectively.

[0013] Preferably, the cleaning component is a long metal strip with a triangular cross-section, and the cleaning component is bolted to the inner wall of the vertical groove on the side near the revolving door.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when a pig enters the feeding system and stands on the support platform, its weight causes the support platform to descend, which in turn moves the first movable column and the first piston of the hydraulic trigger mechanism downward. This forces the hydraulic oil in the first cylinder to flow into the second cylinder of the hydraulic control mechanism through the second connecting pipe, pushing the second piston and the second movable column to move. This movement is then driven by the rack and pinion transmission to rotate the rotating rod, closing the rotating doors on both sides. This effectively isolates other pigs and prevents them from competing for food. At the same time, the descent of the support platform triggers the infrared sensor of the sliding trigger component, which, together with the optical weighing probe, performs non-contact weighing of the pig. The feeding mechanism then dispenses the feed. When the pig finishes eating and leaves the support platform, the elastic element pushes the support platform back to its original position, the hydraulic transmission reverses, and the rotating doors automatically open, allowing the pig to exit. This achieves automated isolation, weighing, and feeding, improving feeding efficiency.

[0015] 2. In the process of closing the revolving door, the rack and pinion of the hydraulic control mechanism moves synchronously to drive the transmission rod to rotate. The transmission rod drives the long rod of the unwinding assembly to rotate through the gear, unwinding the elastic fabric. After the elastic fabric is unwound, it covers the angle between the revolving door and the side fence, preventing other pigs from sticking their heads into the gap, thus avoiding obstructing the normal opening of the revolving door and ensuring the isolation effect. When the revolving door is opened, the long rod rotates in the opposite direction under the drive of the transmission rod to wind up the elastic fabric. The limiting plate ensures that the elastic fabric will not deviate when it is wound up.

[0016] 3. During the movement of the elastic fabric, it is guided by the first and second auxiliary rollers of the auxiliary guide assembly to change the direction of the fabric, ensuring that the elastic fabric moves smoothly during the winding and unwinding process, reducing friction and jamming, and extending its service life.

[0017] 4. The cleaning component is designed as a long metal strip with a triangular cross-section. When the elastic fabric is rolled up, its surface passes through the cleaning component, and the edge of the triangle scrapes off the feed impurities adhering to it, preventing the feed impurities rubbed by the pigs from being rolled into the elastic fabric and avoiding affecting the rolling effect of the elastic fabric.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-17As shown, an intelligent feeding system for a farm includes side fences 100 and feed troughs 200. Two sets of side fences 100 are respectively located on both sides of the feed troughs 200. The system also includes a fixed platform 300, a support platform 400, a hydraulic triggering mechanism 500, a rotating door 600, a hydraulic control mechanism 700, a dispensing mechanism 800, and an optical weighing probe 900. The fixed platform 300 is located between the two side fences 100, with one side of the fixed platform 300 being inclined. The support platform 400 is located on one side of the fixed platform 300 and has the same width as the fixed platform 300. Two sets of rotating doors 600 are located on both sides above the inclined surface of the fixed platform 300. Rotating rods 610 are welded to the surface of the rotating door 600, and the rotating rods 610 are fixed to the side fences 100 via bearing seats, enabling the rotating door 600 to rotate. To prevent pigs standing at the entrance of the fixed platform 300 from being injured by the rotating door 600 after it closes and reopens... Figure 17 The diagram shows the revolving doors 600 after they are closed. At this time, there is an angle between the revolving doors 600 and the side fence 100. Other pigs may stick their heads into this angle after eating or not eating, thus preventing the revolving doors 600 from opening properly and the pigs inside from getting out. The surface of the revolving doors 600 is fixedly connected with a retractable elastic fabric 620. Figure 17 After the rotating doors 600 on both sides are closed, the elastic fabric 620 covers the aforementioned angle to prevent the pig's head from entering and obstructing the normal opening of the rotating doors 600. The optical weighing probe 900 is set between the side rails 100 on both sides. The top of the side rails 100 is also bolted with a fixing rod 910, and the fixing rod 910 is bolted to the optical weighing probe 900 to fix it. The optical weighing probe 900 is externally connected to the optical weighing instrument itself, and the optical weighing instrument is electrically connected to the system, such as the PLC or program in the system (these are current mature technologies and will not be described in detail here). The surface of the side rails 100 is also provided with a pressure sensor 130, which is connected to the program or controller in the system. When the rotating doors 600 are not triggered, the rotating doors 600 and the pressure sensor 130 are in contact with each other.

[0022] A hydraulic trigger mechanism 500 is located below the support platform 400 and provides vertical movement for the support platform 400. The hydraulic trigger mechanism 500 provides support to the support platform 400 using elastic force. Specifically, the hydraulic trigger mechanism 500 includes a base 510, an elastic element 520, a hydraulic push-pull assembly 530, and a sliding trigger assembly 540. The base 510 is located below the support platform 400. The top of the elastic element 520 is in contact with the top of the support platform 400. There are two sets of hydraulic push-pull assemblies 530, which are located on both sides of the top of the base 510. The hydraulic push-pull assemblies 530 are connected to the hydraulic control mechanism 700. There are four sets of sliding trigger assemblies 540, which are located at the four corners of the top of the base 510. Vertical columns 410 are bolted to the four corners of the bottom of the support platform 400, and the sliding trigger assemblies 540 are in contact with the vertical columns 410.

[0023] Furthermore, the hydraulic push-pull assembly 530 includes a first cylinder 531, a support plate 532, a first movable column 533, and a first piston 534. The first cylinder 531 is bolted to the top of the first cylinder 531. The support plate 532 is bolted to the periphery of the first cylinder 531 and has a ring-shaped design. The elastic element 520 is a compression spring, and its upper and lower ends are in contact with the support platform 400 and the support plate 532, respectively. Under the action of the support plate 532, the elastic element 520 is prevented from deviating. The first movable column 533 is bolted to the bottom of the support platform 400. The first piston 534 is movably connected to the inner wall of the first cylinder 531. The first piston 534 and the first movable column 533 are fixed to each other. The upward force of the elastic element 520 makes the support platform 400 positioned higher than the fixed platform 300.

[0024] The sliding trigger assembly 540 consists of a sliding sleeve 541, a connecting rod 542, and an infrared sensor 543. The bottom end of the connecting rod 542 is bolted to the base 510, and the other end of the connecting rod 542 is welded to the sliding sleeve 541. The vertical column 410 is in contact with the inner wall of the sliding sleeve 541 and is slidably connected. The infrared sensor 543 is disposed through the surface of the connecting rod 542, and the infrared sensor 543 here is also connected to the system controller.

[0025] The hydraulic control mechanism 700 uses the hydraulic power of the hydraulic trigger mechanism 500 to control the opening and closing of the revolving door 600. Specifically, the hydraulic control mechanism 700 includes a second cylinder 710, a second piston 720, a second movable column 730, a connecting plate 740, a rack 750, a transmission rod 760, and a retraction assembly 770. The second cylinder 710 is located above the side rail 100. The top of the side rail 100 is bolted to the housing 120, and the second cylinder 710 is fixed inside the housing 120. The second cylinder 710 is connected to the first cylinder 531, and the second piston 720 slides against the inner wall of the second cylinder 710. The second movable column 730 is fixed to the second piston 720. The connecting plate 740 is bolted to the end of the second movable column 730 away from the second piston 720. The rack 750 has a double-sided toothed design and is bolted to the connecting plate 740. One tooth of the rack 750 is connected to the rotating rod 610 through gear transmission. The transmission rod 760 is rotatably connected to the inner wall of the housing 120. The transmission rod 760 is connected to the other tooth of the rack 750 through gear transmission. The winding and unwinding assembly 770 follows the opening and closing of the rotating door 600 to wind or unwind the elastic fabric 620. The surface of the first cylinder 531 A first connecting pipe 535 and a second connecting pipe 536 are respectively connected. The other ends of the first connecting pipe 535 and the second connecting pipe 536 are respectively connected to both sides of the second cylinder 710, connecting them to each other. The connection point of the first connecting pipe 535 to the first cylinder 531 is located below the first cylinder 531. The connection point of the other end of the first connecting pipe 535 to the second cylinder 710 is located on the side of the second cylinder 710 away from the rack 750. The connection point of the second connecting pipe 536 to the first cylinder 531 is located above the first cylinder 531. The second connecting pipe 536 penetrates the support plate 532. The other end of 536 is connected to the second cylinder 710 at the side of the second cylinder 710 near the rack 750. Before operation, the first cylinder 531, the second cylinder 710, the first connecting pipe 535 and the second connecting pipe 536 are all filled with hydraulic oil. In order to increase the sealing of the inlet and outlet of the first cylinder 531 and the second cylinder 710, an oil seal structure similar to a hydraulic cylinder can be set up so that when the first movable column 533 and the second movable column 730 enter and exit the first cylinder 531 or the second cylinder 710, they can slide along the inner wall of the oil seal at this point to prevent external impurities from entering (similar to a hydraulic cylinder).

[0026] Before the support platform 400 is subjected to pressure, the elastic element 520 applies an upward force to the support platform 400, making the height of the support platform 400 higher than that of the fixed platform 300. Simultaneously, this causes the first movable column 533, the first piston 534, and the vertical column 410 to rise. The vertical column 410 can slide along the inner wall of the sliding sleeve 541. Afterward, the bottom of the vertical column 410 is higher than the infrared sensor 543, at which point the infrared sensor 543 is in an untriggered state. Simultaneously, the first piston 534 pushes a portion of the hydraulic oil from the upper part of the first cylinder 531 into the second connecting pipe 536. At this point, the direction of hydraulic oil propulsion on this side of the second connecting pipe 536 is: hydraulic oil from the upper part of the first cylinder 531 → hydraulic oil inside the second connecting pipe 536 → hydraulic oil inside the second cylinder 710 near the rack 750, causing the hydraulic oil on this side to... As the hydraulic pressure increases, it pushes the second piston 720, causing the second movable column 730 to retract into the second cylinder 710. This, in turn, causes the rack 750 to move closer to the second cylinder 710. On the side inside the first connecting pipe 535, there is hydraulic oil from the side of the second cylinder 710 away from the rack 750 → hydraulic oil inside the first connecting pipe 535 → hydraulic oil below the inside of the first cylinder 531. Therefore, when the first piston 534 rises, it causes the first movable column 533 to extend outward from the first cylinder 531. This causes the second piston 720 to retract the second movable column 730 into the second cylinder 710. Conversely, when the first movable column 533 retracts, it causes the second movable column 730 to extend. When the second movable column 730 retracts, it drives the rotating rod 610 to rotate via the rack 750 and gears, thus opening the revolving door 600. Figure 2 As shown), conversely, when the second movable column 730 extends, the revolving doors 600 on both sides close (as shown). Figure 17 (As shown).

[0027] As the revolving door 600 moves the elastic fabric 620 during opening and closing, in order to better store the elastic fabric 620, the storage assembly 770 is further composed of a long rod 771 and a limiting plate 772. A cover 110 is also bolted to the side of the side rail 100. The long rod 771 passes through the cover 110 and the shell 120 and is rotatably connected to the point where they pass through. The long rod 771 is connected to the transmission rod 760 through gear transmission. One end of the elastic fabric 620 is fixed to the long rod 771. There are two sets of limiting plates 772, which are respectively bolted to the upper and lower sides of the surface of the long rod 771. The elastic fabric 620 is made of waterproof cloth.

[0028] To prevent the elastic fabric 620 from moving more stably during winding or unwinding, an auxiliary guide assembly 140 is further provided on the surface of the side rail 100. The auxiliary guide assembly 140 consists of a vertical groove 141, a first auxiliary roller 142, a second auxiliary roller 143, and a cleaning component 144. The vertical groove 141 is formed on the surface of the side rail 100 and communicates with the interior of the cover 110. The first auxiliary roller 142 is rotatably connected to the inner wall of the vertical groove 141, and two rows of the first auxiliary roller 142 are provided. The second auxiliary roller 143 is fixed to the side rail 100 through bearing seats. To enable itself to rotate, the elastic fabric 620 comes into contact with the first auxiliary roller 142 and the second auxiliary roller 143 respectively. As it subsequently travels to the side rail 100 of the fixed platform 300, the cleaning component 144 is a long metal strip with a triangular cross-section. The cleaning component 144 is bolted to the inner wall of the vertical groove 141 near the revolving door 600. Under the action of the first auxiliary roller 142 and the second auxiliary roller 143, the elastic fabric 620 can move smoothly and also adhere to the surface of the cleaning component 144. The triangular design of the cleaning component 144 is similar to a shovel.

[0029] The feeding mechanism 800 is used to supply feed into the feed trough 200. Specifically, the feeding mechanism 800 consists of a feeding pipe 810, a flow meter 820, and a solenoid valve 830. The flow meter 820 and the solenoid valve 830 are connected to an external controller or program. The feeding pipe 810 is connected to the feed conveying pipe (the original feed supply pipe of the breeding house).

[0030] A smart feeding method for livestock farms, employing the aforementioned smart feeding system for livestock farms, is described below in detail: Step A: During feeding, pigs will selectively enter the side pen 100. The first pig to enter moves to the fixed platform 300 and then walks to the support platform 400, which rises. Due to the restriction of the side pen 100, two pigs cannot enter side by side. After the pig walks to the support platform 400, the support platform 400 descends, which drives the first movable column 533 and the first piston 534 to descend, pushing the hydraulic oil to flow. Step B: The first movable column 533 and the first piston 534 descend, using hydraulic oil to push the second piston 720 and the second movable column 730 to move, which in turn moves the rack 750, causing the rotating rod 610 and the rotating door 600 to rotate, closing the rotating doors 600 on both sides and moving the rotating doors 600 away from the pressure sensor 130. At the same time, the vertical column 410 descends and is detected by the infrared sensor 543. Then, the optical weighing probe 900 works to scan the pig's body shape, weigh it, and feed the data back to the system controller. In this way, each pig is weighed using the optical weighing probe 900 before feeding, eliminating the need for staff to enter the pigpen and weigh the pigs by hand, making it more convenient. Handheld optical weighing instruments capture pig body size data (such as body length, body height, chest width, etc.) using 3D cameras or machine vision technology, and convert volume into weight by combining algorithms or mathematical models (such as regression analysis). The device can be operated directly in the pen without moving the pig, reducing stress and enabling rapid, non-contact weight estimation. If another pig follows into the inner side of the fence 100 during the closing process of the revolving door 600, the revolving door 600 will be blocked and cannot close smoothly. At the same time, the support platform 400 will continue to descend because the revolving door 600 cannot continue to move. The vertical column 410 will not descend to the position that triggers the infrared sensor 543. Therefore, the system will not perform weighing or feed delivery. Moreover, the revolving door 600 closes by rotating horizontally, using the gravity of the pigs waiting to eat. This not only saves the power source but also avoids the use of electrical components such as motors that could cause problems for subsequent pigs. Step C: During the closing process of the revolving door 600, the rack 750 can also synchronously drive the transmission rod 760 to rotate, and the transmission rod 760 drives the long rod 771 to rotate, unwinding the elastic fabric 620 wrapped around the surface until the revolving door 600 is closed (e.g., Figure 17 As shown), at this time, the elastic fabric 620 covers the angle between the revolving door 600 and the side fence 100 to prevent pigs that want to enter from behind from sticking their heads into this angle, causing the revolving door 600 to be unable to open normally. Step D: After weighing, the feed is supplied through the external pipeline of the system. The solenoid valve 830 is opened to keep the feed supply pipeline 810 unobstructed. The flow meter 820 measures the feed (the amount of feed is based on the table of pig weight and feed amount, existing technology). The feed falls into the trough 200 and feeding begins. Step E: After the pig finishes eating, there is no feed or only a small amount of feed left in the feeding trough 200. The pig will walk back and forth. When it walks onto the fixed platform 300, the force of the elastic element 520 pushes the support platform 400 upward and resets. Simultaneously, it drives the first movable column 533 and the first piston 534 to move upward. Using hydraulic transmission, the second piston 720 drives the second movable column 730 to move. The rack 750 drives the transmission rod 760 and the rotating rod 610 to rotate, opening the rotating door 600. In step F, the transmission rod 760 synchronously drives the long rod 771 to rotate, following the opening rotating door 600 to wind up the elastic fabric 620. The limiting plate 772 prevents the elastic fabric 620 from deviating vertically. At the same time, the elastic fabric 620 is guided during the winding process by the action of the first auxiliary roller 142 and the second auxiliary roller 143. During the winding process, the surface of the elastic fabric 620 near the outer side may be contaminated with feed impurities from the pigs outside. In order to prevent impurities from being rolled in and affecting the normal winding of the elastic fabric 620, the cleaning component 144 is used to remove most of the feed impurities on the elastic fabric 620 to prevent affecting the winding.
