Description

Technical Field

[0001] The present invention relates to the technical field of marine feed feeding systems, and in particular to a feeding machine and a working method thereof. Background Art

[0002] Nowadays, the aquaculture industry basically adopts centralized breeding. Feed feeding is the core of aquaculture, but the traditional feeding method can no longer meet the growing production capacity demand, so mechanized breeding has emerged. Among them, the use of feeders for feed transportation and feeding is an important method. The use of feeders can effectively improve breeding efficiency.

[0003] To meet the feeding needs of aquaculture, many types of feeders have emerged on the market. However, due to the characteristics of feed, feed residues are easily left in the feeder pipe during feeding, compromising hygiene and epidemic prevention. The accumulation of residual feed can also reduce the performance of the feeding system. Existing methods for cleaning pipes commonly use either disassembly or tool-based cleaning, such as robotic or liquid cleaning systems. Disassembly cleaning is cumbersome and inefficient. Tool-based cleaning, however, is complex, difficult to maintain, and highly specialized for robotics, making it unsuitable for harsh aquaculture environments. Liquid cleaning, on the other hand, presents challenges with fluid selection and pipe drying, both of which increase overall costs. Furthermore, all of these cleaning methods require manual intervention or external tools, which are not only cumbersome to carry but also require additional assembly, significantly reducing cleaning efficiency. Consequently, existing feeders suffer from poor adaptability for post-feed pipe cleaning, the inability to centrally house the feeding and cleaning modules, portability issues, and low cleaning efficiency.

[0055] like Figure 1 - Figure 9 As shown, the present application provides a feeding machine 1, comprising:

[0056] The feeding bin 10 is provided with a feeding port 11 and a discharging port 12;

[0057] The material throwing pipe 20 is connected to the material discharge port 12;

[0058] The first switch valve 30 is connected between the discharge port 12 and the throwing pipe 20 to control the opening and closing of the discharge port 12;

[0059] A driving member 40 connected to the starting end of the throwing pipe 20;

[0060] The cleaning component 50 includes a cleaning pipe 51, a cleaning ball 52, a second switch valve 53 and a third switch valve 54. The cleaning pipe 51 includes a cleaning section 511 and a return section 513. The two ends of the cleaning section 511 are respectively connected to the side of the throwing pipe 20 near the starting end and the side of the feeding bin 10 near the feeding port 11. The two ends of the return section 513 are respectively connected to the side of the throwing pipe 20 near the end and the side of the feeding bin 10 near the feeding port 12. The cleaning ball 52 is arranged in the cleaning pipe 51 and is located between the cleaning pipe 51 and the throwing pipe 20 and circulates. The second switch valve 53 is connected between the cleaning section 511 and the throwing pipe 20. The second switch valve 53 is used to control the opening and closing of the passage between the cleaning section 511 and the throwing pipe 20. The third switch valve 54 is connected between the return section 513 and the throwing pipe 20. The third switch valve 54 is used to control the opening and closing of the passage between the return section 513 and the throwing pipe 20.

[0061] The electronic control device 60 is electrically connected to the first switch valve 30 , the driving member 40 , the second switch valve 53 and the third switch valve 54 .

[0062] In the present invention, the feeding silo 10 is a key component, equipped with an inlet 11 and an outlet 12. The design of this silo 10 allows for convenient material entry and storage, followed by delivery through the outlet 12. To ensure smooth material transfer from the feeding silo 10 to the next processing step, a material delivery pipe 20 is designed. It is directly connected to the outlet 12 and, through the rotation of the pipe body, its delivery port can be aligned with the desired delivery location.

[0063] In order to better control the material feeding process, we set a first switch valve 30 between the discharge port 12 and the throwing pipe 20. The function of this valve is to control the opening and closing of the material discharge, ensuring that the material can be smoothly transferred from the feeding bin 10 to the throwing pipe 20 when needed. The first switch valve 30 can be a manual mechanical switch valve, such as a ball valve, gate valve, butterfly valve, check valve, etc., or it can be an electrical control valve, such as a solenoid valve, electric valve, pneumatic valve, intelligent control valve, etc. The first control valve can control the opening and closing of the channel between the feeding bin 10 and the throwing pipe 20 to open or close the material in the feeding bin 10 to fall into the throwing pipe 20. In addition, in order to drive the movement of the material in the throwing pipe 20, we also designed a drive component 40, which is connected to the starting end of the throwing pipe 20. Through its power, it can effectively push the material to move along the throwing pipe 20. Optionally, the driving member 40 may be an air compressor, a vortex ejector, a gas ejector, etc., which generates power by compressing air, uses air pressure to push the particulate material in the pipeline to move, and finally throws it out from the ejection port of the pipeline.

[0064] For the specific feeding working principle, refer to Figure 9 After the granular material enters the pipeline, due to its small mass, it is pushed by the air generated by the driving element 40. At the same time, due to the laminar flow of the air in the pipeline, the air velocity in the center of the pipeline is the fastest, further propelling the granular material forward in the pipeline until it is thrown out of the pipeline outlet, thus achieving the throwing function. Various types of pneumatic feeding machines currently available on the market have fully demonstrated the feasibility of this pneumatic feeding method.

[0065] The second reason is the cause of feed residue. Figure 9 Due to the laminar flow of air, the air velocity is fastest in the center of the pipe; however, according to Newton's law of internal friction, the closer to the pipe wall, the lower the air velocity, until it is almost zero at the pipe wall, making it impossible for the pellet feed on the side of the pipe wall to obtain sufficient thrust, and eventually causing some feed to accumulate on the pipe wall in the direction of gravity.

[0066] In order to ensure that the throwing pipe 20 remains clean during use, we have designed a set of cleaning components 50. This set of cleaning components 50 includes a cleaning pipe 51, a cleaning ball 52, a second switch valve 53 and a third switch valve 54. The cleaning pipe 51 is divided into a cleaning section 511 and a return section 513. The two ends of the cleaning section 511 are respectively connected to the side of the throwing pipe 20 close to the starting end and the side of the feeding bin 10 close to the feeding port 11, while the two ends of the return section 513 are respectively connected to the side of the throwing pipe 20 close to the end and the side of the feeding bin 10 close to the feeding port 12. The cleaning ball 52 is arranged in the cleaning pipe 51 and is located between the cleaning pipe 51 and the throwing pipe 20 and can move in a circulation. The second switch valve 53 is connected between the cleaning section 511 and the throwing pipe 20, and is used to control the opening and closing of the passage between the cleaning section 511 and the throwing pipe 20. The third switch valve 54 is connected between the return section 513 and the material throwing pipe 20 to control the opening and closing of the passage between the return section 513 and the material throwing pipe 20 .

[0067] For the specific principle of cleaning the pipe 51 with the cleaning ball 52, refer to Figure 9 When the diameter of the ball + the diameter of the pellet feed ≈ the inner diameter of the pipe wall, the ball will block the air duct inside the pipe wall, and the air at the center of the pipe will be dispersed to the pipe wall, causing the air to concentrate on the position of the residual pellet feed on the pipe wall, forming a local laminar flow phenomenon near the center line of the pellet feed, which greatly increases the air flow rate at the center line of the pellet feed. At the same time, due to the reduction in contact area, the center flow rate of the pellets at this time is faster than the center flow rate during normal feeding, so it will definitely push the residual pellet feed to the designated location, thereby completing the cleaning operation.

[0068] Furthermore, the balls are made of natural rubber, with a density of approximately 0.913, while the density of pellet feed is generally greater than 1. Therefore, if the pellet feed can be pushed, the balls must also be pushed and move within the pipe. Therefore, to achieve this function, the diameter of the ball + the diameter of the pellet feed must be ≈ the inner diameter of the pipe wall.

[0069] Optionally, the cleaning pipe 51 can be an integral pipe, with both ends of the pipe being connected to the two ends of the throwing pipe 20 respectively, and the middle part of the pipe being connected to the feeding bin 10, so as to realize the recovery and discharge of residual feed into the feeding bin 10; it can also be a pipe divided into two sections, namely the cleaning section 511 and the return section 513, the cleaning section 511 realizes the lowering of the cleaning balls 52 into the throwing pipe 20, and the return section 513 realizes the recovery of the cleaning balls 52 and residual feed, and then returns the recovered cleaning balls 52 to the cleaning section 511 through the feeding bin 10, so as to realize the recycling and utilization of the cleaning balls 52.

[0070] In addition, for the optimization of the cleaning section 511 and the return section 513, the cleaning section 511 and the return section 513 can be set as connecting pipes with an arc-shaped inclined angle. In this way, setting the pipes of the cleaning section 511 and the return section 513 to be inclined can help the cleaning balls 52 and residual materials to flow freely, reduce the residual materials in the pipe, and improve the utilization rate of the materials and the cleanliness of the pipe.

[0071] Optionally, the connection method between the cleaning section 511 and the return section 513 and the throwing pipe 20 and the feeding bin 10 can be set to a quick-release connection method, such as threaded connection, snap connection, key connection, etc., to achieve rapid disassembly and assembly of the cleaning section 511 and the return section 513 and the throwing pipe 20 and the feeding bin 10, and then the cleaning section 511 and the return section 513 can be disassembled for cleaning, replacement, etc., thereby maintaining the cleanliness and smoothness of the cleaning pipe 51.

[0072] Alternatively, for the cleaning ball 52, the material of the sphere can be rubber, polyurethane, nylon, metal, etc. The sphere made of rubber material has good elasticity and wear resistance, is suitable for most piping systems, and rubbers of different hardness levels can be selected as needed. The sphere made of polyurethane material has higher wear resistance and chemical resistance, and is suitable for pipes containing corrosive media. The sphere made of nylon material has good tensile strength and wear resistance, and is used for applications that require higher hardness and wear resistance, especially in high temperature environments. The sphere made of metal material, such as stainless steel, copper, etc., is used in situations that require high strength and wear resistance, and can be used for the removal of hard deposits. The operator can carry cleaning balls 52 of different materials and sizes and replace them according to different cleaning needs.

[0073] In addition, for the optimization of the cleaning ball 52, a cleaning net can be located on the outer periphery of the sphere and covered with the cleaning net. The material of the cleaning net can be stainless steel, nylon, polyester fiber, etc. The cleaning net made of stainless steel has high corrosion resistance and strength and is suitable for a variety of media environments. The cleaning net made of nylon has good flexibility and wear resistance and is suitable for light cleaning tasks and can be used to prevent damage to the inner wall of the pipe. The cleaning net made of polyester fiber has good chemical stability and wear resistance and is suitable for cleaning balls 52 that need to be used for a long time. Through the coordination of the sphere and the cleaning net, the cleaning ability of the cleaning ball 52 can be improved, the cleaning intensity is increased, and the overall cleaning effect of the device is improved.

[0074] To achieve automated control of the entire system, we've designed an electronic control device 60. This device is electrically connected to the first on-off valve 30, the driver 40, the second on-off valve 53, and the third on-off valve 54, enabling centralized control of the entire system. This allows for precise control of material delivery and the cleaning of the ejection pipe 20.

[0075] The present invention integrates the feeding module and cleaning module within the feeder by providing a feeding bin 10, a feeding pipe 20, a first on-off valve 30, a driver 40, a cleaning assembly 50, and an electronic control device 60. This integrated design not only improves the efficiency of the equipment but also facilitates assembly, disassembly, and replacement of the various components. Furthermore, since these components are modular in design, they can be easily replaced to accommodate pipes of varying diameters, significantly improving the adaptability of the equipment.

[0076] To clean the throwing pipe 20, we employ a unique design: a cleaning ball 52. This ball 52 is deformable, adapting to pipes of varying diameters, enabling precise cleaning of diverse pipes. More importantly, the cleaning ball 52 is pneumatically propelled to move, eliminating the need for cleaning fluids and the risk of pipe drying. This not only improves cleaning efficiency but also reduces overall costs.

[0077] When material feeding is required, the electronic control device 60 controls the opening of the first switch valve 30 and the driving member 40, while keeping the second switch valve 53 and the third switch valve 54 closed. The material falls from the feeding bin 10 and is thrown out through the discharge port 12 of the throwing pipe 20. When the material feeding is completed, the cleaning ball 52 has been placed in the cleaning section 511 of the cleaning pipe 51 in advance. At this time, the electronic control device 60 controls the closing of the first switch valve 30, and opens the second switch valve 53 and the driving member 40, while keeping the third switch valve 54 closed. The cleaning ball 52 falls from the cleaning section 511 into the throwing pipe 20, and moves along the throwing pipe under the push of the driving member 40, and the remaining material is pushed out along the discharge port 12 of the throwing pipe by the cleaning ball 52. In addition, an "X"-shaped metal mesh is provided at the discharge port 12 of the throwing pipe. When the cleaning ball 52 reaches the position of the metal mesh, it will be restricted and stopped, and most of the residual material will continue to be thrown along the material pipe, and part of the material will be stuck at the interface between the throwing pipe 20 and the second switch valve 53.

[0078] After the pipe is cleaned, the electronic control device 60 closes the second on-off valve 53 and the driver 40, and opens the third on-off valve 54 to retrieve the cleaning ball 52. The cleaning ball 52 then falls from the ejection pipe 20 into the return section 513, where it falls by gravity into the feeding bin 10 and then back into the cleaning section 511. During this process, any remaining material at the interface between the ejection pipe 20 and the second on-off valve 53 is driven back into the feeding bin 10 by the cleaning ball 52, and then falls back into the cleaning section 511 through the feeding bin 10. After the cleaning ball 52 passes through the second on-off valve 53, it automatically closes. When the cleaning ball 52 returns to the cleaning section 511 after completing its cleaning, it does not fall into the ejection pipe 20, remaining ready for cleaning. This method not only ensures the cleaning of the ejection pipe 20 but also ensures the recovery of the cleaning ball 52, ensuring continuous and efficient operation of the entire system.

[0079] Furthermore, the feeding bin 10 includes a bin body 13 and a filter element 14, the filter element 14 is connected to the inner wall of the bin body 13, the bin body 13 is separated and connected by the filter element 14 to form a filter chamber 131 located above and a feed chamber 133 located below, the feed chamber 133 is connected to the feed port 11 and the discharge port 12, and the filter chamber 131 is connected to the return section 513 and the cleaning section 511.

[0080] The design structure of the feeding silo 10 includes two main parts: a silo body 13 and a filter element 14. The silo body 13 is a sturdy container for storing and processing materials. The filter element 14 is a special component, which is cleverly connected and fixed to the inner wall of the silo body 13. The filter element 14 can be a filter plate, a filter screen, etc. The material of the filter element 14 can be plastic rubber, stainless steel, etc., which is not limited here. This design allows the silo body 13 to form two independent but interconnected spaces through the separation effect of the filter element 14. Located above is the filter chamber 131, which is responsible for filtering and purifying the material. Located below is the discharge chamber 133, whose main function is to control the discharge process of the material. The discharge chamber 133 is connected to the external system through the inlet 11, and the outlet 12 is connected to the throwing pipe 20 to ensure that the material can enter and discharge smoothly. The material and the cleaning balls 52 flow into the filter chamber 131 through the return section 513, and the material flows into the discharge chamber 133 through the filter element 14. The cleaning balls 52 are intercepted by the filter chamber 131 and moved to the edge of the filter chamber 131 by rolling or driving, and then fall into the cleaning section 511 connected to the edge.

[0081] Optionally, a driving component such as a blower, a cylinder, a push plate or a spring plate may be provided in the filter chamber 131. When the cleaning ball 52 reaches the filter chamber 131, the driving component is started to drive the cleaning ball 52 to the edge of the filter chamber 131 to ensure that the cleaning ball 52 falls into the cleaning section 511 connected to the edge.

[0082] To further improve filtration efficiency and cleaning effects, the filter chamber 131 can be designed to be removable. This allows for easy removal of the filter chamber 131 for maintenance when the filter element 14 needs to be replaced or cleaned. The inner wall of the filter chamber 131 can also be provided with projections or grooves to increase the filtration area and enhance the filtration effect.

[0083] In practical applications, the connection between the filter chamber 131 and the feed chamber 133 can be designed to be adjustable to accommodate different material properties and filtration requirements. For example, the gap between the filter element 14 and the inner wall of the bin body 13 can be adjusted by adjusting the mechanism to control the filtration accuracy.

[0084] Furthermore, the filter element 14 is a filter plate, and the filter element 14 is tilted along the direction from the return section 513 to the cleaning section 511 toward the discharge port 12 .

[0085] In the present invention, the filter element 14 specifically refers to a filter plate. To ensure a smooth filtration process, the filter plate is designed to be tilted in the direction from the return section 513 to the cleaning section 511. With this tilted setting, when the cleaning ball 52 reaches the filter chamber 131, it will automatically roll to the edge of the filter chamber 131 due to the effects of the tilt and gravity, and then fall into the cleaning section 511 connected to the edge. In addition, the tilted filter plate ensures that the material is fully filtered before reaching the discharge port 12, thereby ensuring the quality of the final product. In this way, the tilted setting of the filter plate not only optimizes the filtration process but also improves overall production efficiency.

[0086] In another embodiment of the present invention, multiple filter plates can be installed within the filter chamber 131. These plates can have a combination of different pore sizes to accommodate the filtration requirements of materials with different particle sizes. For example, a filter plate with a larger pore size can be installed near the return section 513 to initially filter larger particles; while a filter plate with a smaller pore size can be installed near the cleaning section 511 to further filter and ensure the purity of the material. This graded filtration method can effectively improve filtration efficiency and accuracy, while reducing filter plate clogging and extending the service life of the equipment.

[0087] Furthermore, to further enhance the filtration effect, auxiliary filter elements, such as magnetic materials or adsorbent materials, may be provided within the filter chamber 131 to remove any small metal particles or organic impurities that may be present in the material. These auxiliary filter elements may be used in conjunction with the filter plates or independently provided between the filter plates or in specific areas of the filter chamber.

[0088] A collection device for the cleaning balls 52, such as a collection trough or bag, can be provided within the cleaning section 511 of the filter chamber 131 to facilitate ball recovery and reuse. The collection device should be designed to ensure smooth ball collection while preventing material leakage. This effectively reduces ball consumption and lowers production costs.

[0089] In summary, the present invention not only improves filtration efficiency and precision by optimizing the design of the filter chamber 131, but also further ensures material purity through graded filtration and the use of auxiliary filter elements. Furthermore, by rationally designing the recycling method for the cleaning balls, production costs are effectively reduced, improving overall economic benefits.

[0090] Furthermore, the feeding bin 10 further includes a bin cover 15 , which is rotatably connected to the edge of the bin body 13 at the feed opening 11 to rotate to open or close the feed opening 11 .

[0091] The silo cover 15 is designed to better control the material delivery process, ensuring safe and convenient operation, and ensuring a tight seal within the silo body 13 during the delivery process. Specifically, the silo cover 15 is tightly connected to the edge of the feed inlet 11 of the silo body 13 via a rotating connection. This design allows the silo cover 15 to be flexibly rotated to open or close the feed inlet 11.

[0092] When materials need to be added to the silo, the operator can easily rotate the silo cover 15 from a closed state to an open state, thereby exposing the feed port 11 and facilitating the smooth entry of materials. Once the materials have been added, the operator simply rotates the silo cover 15 again, returning it from an open state to a closed state, effectively covering the feed port 11 and preventing materials from spilling out or foreign matter from entering the silo. This rotating connection design not only improves operational convenience but also ensures safety throughout the entire feeding process, avoiding accidents that could arise from improper operation.

[0093] Furthermore, the swivel connection of the silo cover 15 also features a self-locking function. Once fully opened or closed, the special structural design of the swivel connection automatically locks the cover in place, preventing accidental opening or closing due to vibration or unexpected collisions. This self-locking feature significantly enhances the stability and reliability of the feeder during operation.

[0094] To further enhance operational safety, the silo cover 15 is equipped with a safety latch. When the cover 15 is open, the operator can use the latch to secure it in the open position, preventing it from accidentally closing during material delivery and potentially harming the operator. Furthermore, the latch can be locked when the cover 15 is closed, preventing it from accidentally opening during transport or movement, ensuring safe storage of materials.

[0095] In practice, the design of the feeder's silo cover 15 also takes into account the characteristics of different materials. For flammable, explosive, or environmentally sensitive materials, the sealing performance of the silo cover 15 is particularly important. Therefore, a sealing strip is designed at the connection between the silo cover 15 and the silo body 13. This ensures that when the silo cover 15 is closed, the feed inlet 11 is effectively sealed, preventing material leakage and the ingress of external air, thereby ensuring the quality and safety of the materials.

[0096] Furthermore, the feeder also includes a first sensor 70, which is electrically connected to the electronic control device 60. The first sensor 70 is arranged between the first switch valve 30 and the throwing pipe 20. The first sensor 70 is used to detect whether there is material entering the throwing pipe 20 from the discharge port 12.

[0097] The first sensor 70 can be a photoelectric sensor, an ultrasonic sensor, a capacitive proximity sensor, a magnetic induction sensor, an infrared proximity sensor, an inductive proximity sensor, or the like. When the cleaning ball 52 is made of metal or has a metal cleaning net on its surface, a photoelectric sensor (which uses a single unit to simultaneously transmit and receive light, detecting the presence of an object by detecting the reflected light), an ultrasonic sensor (which uses the principles of ultrasonic transmission and reception to measure distance and can detect the presence of an object when an object blocks the ultrasonic wave), a capacitive proximity sensor (which detects the presence of an object by detecting changes in capacitance caused by the object, suitable for detecting both metal and non-metallic objects), an infrared proximity sensor (which transmits infrared light and receives reflected signals to determine the presence of an object), or an inductive proximity sensor (primarily used to detect metal objects, detecting the presence of an object by detecting changes in the magnetic field around a coil) can be used to detect the approach of the cleaning ball 52. Alternatively, a magnetic element can be provided inside the cleaning ball 52, in which case a magnetic induction sensor (used to detect the presence of magnetic objects) can be used to detect the approach of the cleaning ball 52. By setting a first sensor 70 between the first switch valve 30 and the throwing pipe 20, the material in the feeding bin 10 can be sensed and identified to enter the throwing pipe 20. The degree of completion of the feeding bin 10 is judged by judging the presence or absence of the identification signal, so as to ensure the accuracy of the quantitative feeding of the feeding bin 10 and improve the degree of automation of the feeding process of the feeding machine and the connection with the subsequent cleaning process.

[0098] Furthermore, the feeder also includes a second sensor 80, which is electrically connected to the electronic control device 60. The second sensor 80 is arranged between the second switch valve 53 and the throwing pipe 20. The second sensor 80 is used to detect whether the cleaning ball 52 enters the throwing pipe 20 from the cleaning section 511.

[0099] The second sensor 80 can be a photoelectric sensor, an ultrasonic sensor, a capacitive proximity sensor, a magnetic induction sensor, an infrared proximity sensor, an inductive proximity sensor, etc. By providing the second sensor 80 between the second on-off valve 53 and the ejection pipe 20 , it can sense and identify the entry of the cleaning ball 52 from the cleaning section 511 into the ejection pipe 20 , thereby ensuring the effectiveness of cleaning and the orderliness of subsequent cleaning actions (activating the drive member 40 after the cleaning ball 52 is lowered), thereby improving the automation of the feeder cleaning process.

[0100] Furthermore, the feeder also includes a third sensor 90, which is electrically connected to the electronic control device 60. The third sensor 90 is arranged on the side wall of the throwing pipe 20 close to the return section 513. The third sensor 90 is used to detect whether the cleaning ball 52 reaches the end of the throwing pipe 20.

[0101] The third sensor 90 can be a photoelectric sensor, an ultrasonic sensor, a capacitive proximity sensor, a magnetic induction sensor, an infrared proximity sensor, an inductive proximity sensor, etc. By providing the third sensor 90 on the wall of the material throwing pipe 20 near the return section 513 , it can sense and identify the arrival of the cleaning ball 52 at the outlet of the material throwing pipe 20 , thereby ensuring the effectiveness of cleaning and the orderliness of subsequent cleaning operations (opening the third on-off valve 54 to allow the cleaning ball 52 to descend to the return section 513 ), thereby improving the automation of the feeder cleaning process.

[0102] In the structural design of the feeder, in order to further improve the intelligence level of the equipment, a fourth sensor is also introduced. The fourth sensor is also electrically connected to the electronic control device 60, and its position is set at the end of the return section 513, and is used to detect whether the cleaning ball 52 has successfully returned to the collection box 55. The fourth sensor can adopt the same sensor type as the first three, such as a photoelectric sensor, an ultrasonic sensor, etc. By setting the fourth sensor at the end of the return section 513, it is possible to accurately monitor whether the cleaning ball 52 has completed the entire cleaning cycle and has been successfully recovered, thereby ensuring that the cleaning process of the entire feeder is both efficient and reliable. Such a design not only improves the cleaning efficiency, but also reduces the need for manual intervention, further improving the automation level and production efficiency of the entire feeder.

[0103] Furthermore, the feeding machine also includes a base 100 and a pressure sensor 110. The feeding bin 10 is installed on the base 100. The pressure sensor 110 is arranged between the base 100 and the feeding bin 10. The pressure sensor 110 is electrically connected to the electronic control device 60. The pressure sensor 110 is used to detect the weight of the feeding bin 10.

[0104] The pressure sensor 110 converts the gravity change into an analog quantity and feeds it back to the electronic control device 60. The data detection before feeding and the continuous data detection during feeding are compared, and then the quantitative feeding of the feeding bin 10 is achieved by controlling the first switch valve 30.

[0105] The core part of the feeding machine includes a base 100 and a pressure sensor 110. The base 100 serves as the foundation of the entire equipment and provides a stable support for the feeding bin 10. The feeding bin 10 is installed on the base 100, and its main function is to store the materials to be fed. In order to accurately monitor the weight of the feeding bin 10, one or more pressure sensors 110 are cleverly placed between the base 100 and the feeding bin 10. This pressure sensor 110 is connected to the electronic control device 60 through an electrical connection, so that the detected data can be transmitted to the electronic control device 60 in real time. The working principle of the pressure sensor 110 is to sense changes in gravity, convert these changes into corresponding analog signals, and feed these signals back to the electronic control device 60.

[0106] In this way, the electronic control device 60 can receive real-time data on the weight of the feeding bin 10. Before feeding, the electronic control device 60 will detect the initial weight of the feeding bin 10, and during the feeding process, the electronic control device 60 will continue to monitor the data fed back by the pressure sensor 110. By comparing the data changes before and after feeding, the reduction of materials in the feeding bin 10 can be grasped in real time to achieve quantitative feeding. The electronic control device 60 precisely controls the first switch valve 30 based on the data provided by the pressure sensor 110. In this way, the feeding machine can realize the function of quantitative feeding, that is, while ensuring that the feeding amount is accurate each time, it can also adjust the preset feeding amount input to the electronic control device 60 according to actual needs. This precise control not only improves the efficiency of feeding, but also improves the stability and reliability of the entire production process.

[0107] Optionally, when there is one pressure sensor 110, it can be arranged at the center of the base 100. When there are multiple pressure sensors 110, the multiple pressure sensors 110 can be distributed at intervals between the base 100 and the feeding bin 10. By collecting data from multiple pressure sensors 110, performing summary statistical calculations, and taking the average value, the accuracy and effectiveness of the detection data can be improved, and the accuracy of the weight control inside the feeding bin 10 can be improved.

[0108] Furthermore, the feeding machine also includes an air pressure balancing component 120, which includes an air pressure balancing pipe 1201 and an air pressure balancing valve 1202. One end of the air pressure balancing pipe 1201 is connected to the feeding bin 10, and the other end is connected to the throwing pipe 20. The air pressure balancing valve 1202 is installed on the air pressure balancing pipe 1201. The air pressure balancing component 120 is used to adjust the air pressure inside the feeding bin 10.

[0109] The air pressure balancing assembly 120 consists of two main components: an air pressure balancing pipe 1201 and an air pressure balancing valve 1202. One end of the air pressure balancing pipe 1201 is tightly connected to the feeding bin 10, while the other end is connected to the material throwing pipe 20. This design enables the air pressure balancing pipe 1201 to form an effective air pressure transmission channel between the feeding bin 10 and the material throwing pipe 20.

[0110] In order to further adjust and control the air pressure balance, the air pressure balance valve 1202 is installed on the air pressure balance pipe 1201. The air pressure balance valve 1202 can be a manual mechanical switch valve, such as a ball valve, a gate valve, a butterfly valve, a check valve, etc., or an electrical control valve, such as a solenoid valve, an electric valve, a pneumatic valve, an intelligent control valve, etc. The role of this valve is crucial because it can accurately control the inflow and outflow of the air pressure inside the feeding bin 10, thereby ensuring that the air pressure inside the feeding bin 10 is maintained at an ideal level. Specifically, the function of the air pressure balance valve 1202 is to prevent the air pressure delivered to the throwing pipe 20 by the air compressor from being too high, resulting in the air pressure inside the throwing pipe 20 being higher than the air pressure inside the feeding bin 10, causing the external air pressure at the outlet 12 of the feeding bin 10 to be too high.

[0111] By properly adjusting the air pressure balance valve 1202, an appropriate amount of air can be added to the feeding bin 10 so that the internal air pressure and the external air pressure remain relatively balanced, thereby promoting the smooth falling of the material.

[0112] This design not only improves the feeder's operating efficiency but also ensures the stability and reliability of the entire feeding process. Adjusting the air pressure balance assembly 120 effectively prevents material blockage or waste caused by excessively high or low air pressure, ensuring that feed is delivered evenly and continuously to the designated location. Overall, the introduction of the air pressure balance assembly 120 makes the feeder more flexible and efficient during operation, improving the performance of the entire feed conveying system.

[0113] Optionally, sensors for monitoring and regulating air pressure can be installed within the feeding bin 10. These sensors can detect the air pressure status within the feeding bin 10 in real time and transmit the data to the control system. Based on the data provided by the sensors, the control system automatically adjusts the opening of the air pressure balance valve 1202 in conjunction with the electrical control valve to maintain stable air pressure. This automatic adjustment mechanism not only improves operational accuracy but also reduces the need for manual intervention, making the entire feeding process more intelligent and automated.

[0114] Furthermore, to further enhance the feeder's performance and reliability, a fault diagnosis system has been incorporated into the design. This system monitors the feeder's operating status in real time. If it detects an anomaly, such as pressure imbalance, material blockage, or mechanical failure, it immediately issues an alarm and provides appropriate fault information and solutions. This not only facilitates timely troubleshooting but also prevents potential problems, ensuring the feeder's long-term stable operation.

[0115] The present invention also provides a method for operating a feeding machine 1, which utilizes the feeding machine. The specific structure of the feeding machine is similar to the above-mentioned embodiments. Since the present method adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.

[0116] A working method of a feeding machine 1 is applied to the feeding machine as described above. The feeding machine further includes a first sensor 70, a second sensor 80, a third sensor 90 and a pressure sensor 110. The electronic control device 60 is electrically connected to the first sensor 70, the second sensor 80, the third sensor 90 and the pressure sensor 110. The working method of the feeding machine includes the following steps:

[0117] Set the target feeding weight of the feeding bin 10 and control the pressure sensor 110 to detect the real-time weight of the feeding bin 10;

[0118] Controlling the opening of the first switch valve 30 and starting the driving member 40;

[0119] Receive the real-time weight from the pressure sensor 110 and compare it with the target feeding weight;

[0120] If the real-time weight of the pressure sensor 110 reaches the target feeding weight, the first switch valve 30 and the driving member 40 are controlled to close;

[0121] receiving detection data from the first sensor 70;

[0122] If the first sensor 70 detects that no material passes through, it controls the second switch valve 53 to open and the driving member 40 to start;

[0123] receiving detection data from the second sensor 80;

[0124] If the second sensor 80 detects that the cleaning ball 52 passes through, the second switch valve 53 is controlled to close;

[0125] receiving detection data from the third sensor 90;

[0126] If the third sensor 90 detects that the cleaning ball 52 passes through, it controls the driving member 40 to be closed and the third switch valve 54 to be opened;

[0127] The third on-off valve 54 is controlled to be closed.

[0128] The working method of this feeding machine is as follows: when feed needs to be delivered, the target feeding weight of the feeding bin 10 is set to the electronic control device 60, which converts it into an analog value from the pressure sensor 110. The electronic control device 60 receives the data from the pressure sensor 110, converts it into the actual weight inside the feeding bin 10, and continuously monitors the data from the pressure sensor 110. The electronic control device 60 controls the opening of the first switch valve 30 and the drive member 40, while the second switch valve 53 and the third switch valve 54 remain closed. Feed falls from the feeding bin 10 into the throwing pipe 20 and is driven by the drive member 40 to be thrown out along the discharge port 12 of the throwing pipe. When the data monitored by the pressure sensor 110 reaches the preset target feeding weight, the first switch valve 30 is controlled to close. The electronic control device 60 continuously monitors the signal from the first sensor 70. When the electronic control device 60 receives the signal from the first sensor 70 indicating that no material has passed, it indicates that the material discharge is complete.

[0129] When the feed needs to be cleaned after delivery, a cleaning ball 52 is pre-placed in the cleaning section 511 of the cleaning pipe 51. The electronic control unit 60 controls the closing of the first on-off valve 30 and the opening of the second on-off valve 53 and the driver 40. The third on-off valve 54 remains closed, and the cleaning ball 52 falls from the cleaning section 511 into the ejection pipe 20. The electronic control unit 60 continuously monitors the signal from the second sensor 80. When the electronic control unit 60 receives a pass signal from the second sensor 80, the lowering of the cleaning ball 52 is complete. The driver 40 drives the cleaning ball 52 along the ejection pipe, and the residual feed is pushed by the cleaning ball 52 and ejected through the ejection pipe's outlet 12. The electronic control unit 60 continuously monitors the signal from the third sensor 90. When the electronic control unit 60 receives a pass signal from the second sensor 80, the cleaning ball 52 reaches the outlet of the ejection pipe 20, indicating that the cleaning ball 52 has completed cleaning.

[0130] When the cleaning ball 52 needs to be recovered after the pipeline is cleaned, the electronic control device 60 controls the closing of the second switch valve 53 and the driving member 40, and opens the third switch valve 54. The cleaning ball 52 falls from the throwing pipe 20 into the return section 513, falls to the feeding bin 10 by gravity, and then returns to the cleaning section 511. The remaining residual feed is returned to the feeding bin 10 by the driving of the cleaning ball 52.

[0131] Furthermore, in another embodiment, the feeding machine further includes an air pressure balancing assembly 120, which includes an air pressure balancing pipe 1201 and an air pressure balancing valve 1202. Between steps 1 and 2, an additional step of regulating the air pressure in the feeding bin 10 is added: the air pressure balancing valve 1202 is adjusted according to the size and amount of the material particles to add an appropriate amount of air to the feeding bin 10, so that the air pressure inside the feeding bin 10 remains relatively balanced with the external air pressure.

[0132] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
