Description

Technical Field

[0001] The 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, and feed feeding is the core of aquaculture. However, 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] In order to meet the needs of aquaculture, many types of feeders have appeared on the market. However, during the feeding process of the feeder, due to the characteristics of the feed, feed residues are very likely to appear in the feed pipe of the feeder, which is not conducive to the sanitation and epidemic prevention of aquaculture, and the accumulation of residual materials will also cause the performance of the feeding system to decline. For pipeline cleaning, the common methods are pipeline disassembly cleaning or tool cleaning, such as robot cleaning or cleaning liquid cleaning. The pipeline disassembly cleaning method is cumbersome to operate and has low cleaning efficiency; while the tool cleaning method has complex design, difficult maintenance and strong specialization for the robot type, which is not suitable for the harsh aquatic production environment. For the cleaning liquid type, there are problems with liquid selection and pipeline drying, and both will lead to increased comprehensive costs. Moreover, the above cleaning methods all require manual or external tools to participate, which is not only troublesome to carry, but also requires additional assembly, and the cleaning efficiency is significantly low. Therefore, the existing feeders have problems such as low adaptability, inability to centrally set feeding modules and cleaning modules, inconvenient carrying, and low cleaning efficiency for pipeline cleaning after feeding.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] like Figure 1 - Fig. 9 As shown, the present application provides a feeding machine 1, comprising: A feeding bin 10, wherein the feeding bin 10 is provided with a feeding port 11 and a discharging port 12; A material throwing pipe 20, the material throwing pipe 20 is connected to the material discharge port 12; The first switch valve 30 is connected between the discharge port 12 and the throwing pipe 20 to control the discharge opening and closing of the discharge port 12; A driving member 40, the driving member 40 is connected to the starting end of the throwing pipe 20; 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 a side of the throwing pipe 20 close to the starting end and a side of the feeding bin 10 close to the feeding port 11. The two ends of the return section 513 are respectively connected to a side of the throwing pipe 20 close to the end and a 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 for cyclic movement. 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. 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 .

[0027] In the present invention, the feeding bin 10 is a key component, which has an inlet 11 and an outlet 12. The design of the feeding bin 10 allows the material to be easily entered and stored, and then delivered through the outlet 12. In order to ensure that the material can be smoothly transferred from the feeding bin 10 to the next processing link, we designed a throwing pipe 20, which is directly connected to the outlet 12, and through the setting of the rotating pipe body, its throwing port can be aligned with the desired delivery position.

[0028] In order to better control the material delivery 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 to ensure 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, a gate valve, a butterfly valve, a check valve, etc., and can also be an electrical control valve, such as a solenoid valve, an electric valve, a pneumatic valve, an 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 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.

[0029] For the specific feeding working principle, refer to Fig. 9 After the granular material enters the pipeline, it is pushed by the air generated by the driving member 40 due to its small mass. At the same time, due to the laminar flow of the air in the pipeline, the air flow rate in the center of the pipeline is the fastest, which further pushes the granular material forward in the pipeline until the granular material is thrown out of the pipeline port, thus realizing the throwing function. Various types of pneumatic feeders currently available on the market have fully proved the feasibility of this pneumatic feeding.

[0030] The second reason is the cause of feed residue. Fig. 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 granular feed on the side of the pipe wall to obtain sufficient thrust, and eventually causing part of the feed to accumulate on the pipe wall in the direction of gravity.

[0031] 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 discharge 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 be circulated. 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 pipeline 20 to control the opening and closing of the passage between the return section 513 and the material throwing pipeline 20 .

[0032] For the specific principle of cleaning the pipe 51 with the cleaning ball 52, refer to Fig. 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 in the center of the pipe will be dispersed to the pipe wall, so that the air will be concentrated on the position of the residual pellet feed on the pipe wall, forming a local laminar flow phenomenon close to 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 of the contact area, the center flow rate of the pellet 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 position, thereby completing the cleaning operation.

[0033] In addition, the ball is made of natural rubber, and its density is about 0.913, while the density of pellet feed is basically greater than 1. If the pellet feed can be pushed, the ball must also be pushed and move in the pipe. Therefore, in order to achieve this function, it is necessary to make the ball diameter + pellet feed diameter ≈ pipe wall inner diameter.

[0034] 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 of residual feed and discharge it into the feeding bin 10; it can also be a pipe divided into two sections, namely a cleaning section 511 and a return section 513, the cleaning section 511 realizes the lowering of the cleaning balls 52 to 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 of the cleaning balls 52.

[0035] 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 facilitate the free flow of the cleaning ball 52 and residual materials, reduce the residual materials in the pipe, and improve the utilization rate of the materials and the cleanliness of the pipe.

[0036] Optionally, the connection mode 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 mode, such as a threaded connection, a snap connection, a key connection, etc., to achieve quick 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.

[0037] Optionally, for the cleaning ball 52, the material of the sphere can be rubber, polyurethane, nylon, metal material, etc. The sphere of rubber material has good elasticity and wear resistance, is suitable for most pipeline systems, and rubbers of different hardness levels can be selected as needed. The sphere of polyurethane material has higher wear resistance and chemical resistance, and is suitable for pipelines containing corrosive media. The sphere of nylon material has good tensile strength and wear resistance, and is used for applications requiring higher hardness and wear resistance, especially under high temperature conditions. The sphere of metal material such as stainless steel, copper, etc., is used in occasions requiring 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.

[0038] In addition, for the optimization of the cleaning ball 52, a cleaning net can be coated on the outer periphery of the sphere, and 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, is suitable for light cleaning tasks, and can be used to prevent damage to the inner wall of the pipeline. 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 cooperation of the sphere and the cleaning net, the cleaning ability of the cleaning ball 52 can be improved, the cleaning intensity is improved, and the overall cleaning effect of the device is improved.

[0039] In order to realize the automatic control of the whole system, we also designed an electric control device 60. This electric control device 60 is connected with the first switch valve 30, the driving member 40, the second switch valve 53 and the third switch valve 54 by electrical connection, so as to realize the centralized control of the whole system. In this way, we can accurately control the material delivery and the cleaning process of the throwing pipe 20.

[0040] The present invention realizes the integrated setting of the feeding module and the cleaning module in the feeding machine by providing the feeding bin 10, the throwing pipe 20, the first switch valve 30, the driving member 40, the cleaning assembly 50 and the electric control device 60. This integrated design not only improves the use efficiency of the equipment, but also makes the disassembly and replacement of each component more convenient. In addition, since these components are all modularly designed, it is easy to replace pipes adapted to different diameters, which greatly improves the adaptability of the equipment.

[0041] In the process of cleaning the throwing pipe 20, we use a unique design of a cleaning ball 52. The cleaning ball 52 has a certain deformation ability and can adapt to pipes of different diameters, thereby cleaning different pipes. More importantly, we use pneumatics to push the cleaning ball 52 to move for cleaning. This method does not require the use of cleaning liquid, so there is no need to solve the problem of pipe drying. This not only improves cleaning efficiency, but also reduces overall costs.

[0042] When it is necessary to feed the material, the electronic control device 60 will control 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 is fed, 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 will control the closing of the first switch valve 30, and open 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 through the driving member 40, and the remaining material is pushed by the cleaning ball 52 and thrown out along the discharge port 12 of the throwing pipe. 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 out 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.

[0043] When the pipeline cleaning is completed, in order to recycle the cleaning ball 52, the electronic control device 60 will control the closing of the second switch valve 53 and the driving member 40, and open the third switch valve 54. At this time, the cleaning ball 52 will fall from the throwing pipe 20 into the return section 513, fall into the feeding bin 10 by gravity, and then return to the cleaning section 511 again. In this process, the residual material remaining at the interface between the throwing pipe 20 and the second switch valve 53 is driven by the cleaning ball 52 to return to the feeding bin 10, and fall back into the cleaning section 511 through the feeding bin 10. When the cleaning ball 52 passes through the second switch valve 53, the second switch valve 53 will automatically close. When the cleaning ball 52 returns to the cleaning section 511 after cleaning, it will not fall into the throwing pipe 20 and remain in a state to be cleaned. In this way, we not only achieve the cleaning of the throwing pipe 20, but also ensure the recovery of the cleaning ball 52, so that the entire system can operate continuously and efficiently.

[0044] 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 divided and connected by the filter element 14 to form a filter chamber 131 located at the top and a feed chamber 133 located at the bottom, the feed chamber 133 is connected to the feed inlet 11 and the discharge port 12, and the filter chamber 131 is connected to the return section 513 and the cleaning section 511.

[0045] The design structure of the feeding bin 10 includes two main parts: a bin body 13 and a filter element 14. The bin 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 bin 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 bin body 13 to form two independent and 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 feeding chamber 133, whose main function is to control the feeding process of the material. The feeding chamber 133 is connected to the external system through the feed port 11, and the discharge port 12 is connected to the throwing pipe 20 to ensure that the material can enter and discharge smoothly. The material and the cleaning ball 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 ball 52 is intercepted by the filter chamber 131 and moves to the edge of the filter chamber 131 by rolling or driving, and then falls into the cleaning section 511 connected to the edge.

[0046] Optionally, a driving component such as a hair dryer, 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.

[0047] In order to further improve the filtering efficiency and cleaning effect, the filter chamber 131 can be designed as a detachable structure. In this way, when the filter element 14 needs to be replaced or cleaned, the filter chamber 131 can be easily removed for maintenance. On the inner wall of the filter chamber 131, some protrusions or grooves can also be set to increase the filtering area and improve the filtering effect.

[0048] In practical applications, the connection between the filter chamber 131 and the feed chamber 133 can be designed to be adjustable so as to be adjusted according to different material properties and filtering requirements. For example, the gap between the filter element 14 and the inner wall of the bin body 13 can be changed by an adjustment mechanism to control the filtering accuracy.

[0049] Furthermore, the filter element 14 is a filter plate, and the filter element 14 is tiltedly arranged along the direction from the return section 513 to the cleaning section 511 toward the discharge port 12 .

[0050] In the present invention, the filter element 14 specifically refers to a filter plate. In order to ensure the smooth progress of the filtering 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, the cleaning ball 52 will automatically roll to the edge of the filter chamber 131 by virtue of the tilt and gravity, and then fall into the cleaning section 511 connected to the edge. In addition, the tilted filter plate can also ensure that the material is fully filtered before reaching the discharge port 12 to ensure the quality of the final product. In this way, the tilted setting of the filter plate not only optimizes the filtering process, but also improves the overall production efficiency.

[0051] In another embodiment of the present invention, a plurality of filter plates may be provided in the filter chamber 131, and these filter plates may be a combination of different apertures to meet the filtering requirements of materials with different particle sizes. For example, a filter plate with a larger aperture may be provided at one end near the return section 513 for preliminary filtering of materials with larger particles; and a filter plate with a smaller aperture may be provided at one end near the cleaning section 511 for further filtering and ensuring the purity of the materials. This hierarchical filtering method can effectively improve the filtering efficiency and filtering accuracy, while reducing the clogging of the filter plates and extending the service life of the equipment.

[0052] In addition, in order to further improve the filtering effect, auxiliary filtering elements, such as magnetic materials or adsorbent materials, can be arranged in the filter chamber 131 to remove tiny metal particles or organic impurities that may exist in the material. These auxiliary filtering elements can be used in combination with the filter plates, or can be independently arranged between the filter plates or in a specific area of ​​the filter chamber.

[0053] In the cleaning section 511 of the filter chamber 131, a collection device for the cleaning balls 52, such as a collection tank or a collection bag, can be provided to facilitate the recovery and reuse of the cleaning balls. The design of the collection device should ensure that the cleaning balls can fall into it smoothly while preventing leakage of materials. In this way, the consumption of cleaning balls can be effectively reduced and the production cost can be reduced.

[0054] In summary, the present invention not only improves the filtration efficiency and filtration accuracy by optimizing the design of the filter chamber 131, but also further ensures the purity of the material by using graded filtration and auxiliary filter elements. At the same time, by reasonably designing the recycling method of the cleaning ball, the production cost is effectively reduced and the overall economic benefit is improved.

[0055] 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 inlet 11 so as to rotate to open or cover the feed inlet 11 .

[0056] The function of the silo cover 15 is to better control the material delivery process, ensure the safety and convenience of operation, and ensure the sealing of the silo body 13 during the delivery process. Specifically, the silo cover 15 is tightly connected to the edge of the feed port 11 of the silo body 13 by a rotating connection. This design allows the silo cover 15 to be flexibly rotated, thereby realizing the function of opening or closing the feed port 11.

[0057] When materials need to be put into the bin, the operator can easily rotate the bin cover 15 from the closed state to the open state, thereby exposing the feed port 11 and facilitating the smooth entry of materials. When the materials are put into the bin, the operator only needs to rotate the bin cover 15 again, turning it from the open state back to the closed state, to effectively cover the feed port 11 and prevent the materials from overflowing or foreign impurities from entering the bin. This rotating connection design not only improves the convenience of operation, but also ensures the safety of the entire putting process, avoiding accidents that may be caused by improper operation.

[0058] In addition, the rotating connection design of the silo cover 15 also has a certain self-locking function. After the silo cover 15 is opened or closed, due to the special structural design of the rotating connection part, the silo cover 15 can be automatically locked in the corresponding position to prevent accidental opening or closing due to vibration or accidental collision. This self-locking function greatly improves the stability and reliability of the feeder during use.

[0059] In order to further improve the safety of operation, a safety lock device is also provided on the silo cover 15. When the silo cover 15 is open, the operator can use the safety lock to fix the silo cover 15 in the open position to ensure that the silo cover 15 will not be accidentally closed during the material delivery process, thereby avoiding harm to the operator. At the same time, when the silo cover 15 is closed, the safety lock can also be locked to ensure that the silo cover 15 will not be accidentally opened during transportation or movement, thereby ensuring the safe storage of materials.

[0060] In practical applications, the design of the silo cover 15 of the feeder 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 to ensure that when the silo cover 15 is closed, the feed inlet 11 can achieve a good sealing effect to prevent material leakage or external gas from entering, thereby ensuring the quality and safety of the material.

[0061] Furthermore, the feeder also includes a first sensor 70 , which is electrically connected to the electronic control device 60 . The first sensor 70 is disposed 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 .

[0062] The first sensor 70 may be a photoelectric sensor, an ultrasonic sensor, a capacitive proximity sensor, a magnetic induction sensor, an infrared proximity sensor, an inductive proximity sensor, etc. When the cleaning ball 52 is made of metal or has a metal cleaning net on its surface, a photoelectric sensor (a single unit is used to simultaneously emit and receive light, and the presence of an object is determined by detecting the reflected light), an ultrasonic sensor (the distance is measured by the ultrasonic emission and reception principle, and the presence of an object can be detected when an object blocks the ultrasonic wave), a capacitive proximity sensor (the presence of an object is determined by detecting the capacitance change caused by the object. Suitable for detecting metal and non-metal objects), an infrared proximity sensor (emitting infrared rays and receiving reflected signals to determine whether an object exists), and an inductive proximity sensor (mainly used to detect metal objects, and the presence of an object is determined by detecting the change in the magnetic field around the coil) may be used to detect the approach of the cleaning ball 52. Alternatively, a magnetic element may be provided inside the cleaning ball 52, and a magnetic induction sensor (used to detect the presence of magnetic objects) may 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 entering the throwing pipe 20 can be sensed and identified, and 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, thereby improving the degree of automation of the feeding process of the feeder and the connection with the subsequent cleaning process.

[0063] 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, and the second sensor 80 is used to detect whether the cleaning ball 52 enters the throwing pipe 20 from the cleaning section 511.

[0064] 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 arranging the second sensor 80 between the second switch valve 53 and the throwing pipe 20, it is possible to sense and identify that the cleaning ball 52 enters the throwing pipe 20 from the cleaning section 511, so as to ensure the effectiveness of cleaning and the orderliness of subsequent cleaning actions (opening the driving member 40 after the cleaning ball 52 is lowered), thereby improving the automation of the cleaning process of the feeder.

[0065] 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.

[0066] The third sensor 90 may 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 arranging the third sensor 90 on the wall of the material throwing pipe 20 near the return section 513, it is possible to sense and identify the arrival of the cleaning ball 52 at the outlet of the material throwing pipe 20, so as to ensure the effectiveness of cleaning and the orderliness of subsequent cleaning actions (opening the third switch valve 54 to allow the cleaning ball 52 to be lowered to the return section 513), thereby improving the automation of the cleaning process of the feeder.

[0067] 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.

[0068] 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.

[0069] The pressure sensor 110 detects gravity changes and converts them into analog quantities and feeds them back to the electronic control device 60. It uses data detection before feeding and continuous data detection during feeding for comparison, and then controls the first switch valve 30 to achieve quantitative feeding of the feeding bin 10.

[0070] The core part of the feeder includes a base 100 and a pressure sensor 110. The base 100 serves as the foundation of the entire device and provides a stable support for the feed bin 10. The feed 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 feed bin 10, one or more pressure sensors 110 are cleverly placed between the base 100 and the feed 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 the changes in gravity, convert these changes into corresponding analog signals, and feed these signals back to the electronic control device 60.

[0071] 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 accurately controls the first switch valve 30 according to the data provided by the pressure sensor 110. In this way, the feeder can realize the function of quantitative feeding, that is, while ensuring that the feeding amount is accurate each time, the preset feeding amount can be input into the electronic control device 60 for adjustment 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.

[0072] 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 average values, the accuracy and effectiveness of the detection data can be improved, and the precision of the weight control inside the feeding bin 10 can be improved.

[0073] Furthermore, the feeding machine also includes an air pressure balance component 120, which includes an air pressure balance pipe 1201 and an air pressure balance valve 1202. One end of the air pressure balance pipe 1201 is connected to the feeding bin 10, and the other end is connected to the throwing pipe 20. The air pressure balance valve 1202 is installed on the air pressure balance pipe 1201. The air pressure balance component 120 is used to adjust the air pressure inside the feeding bin 10.

[0074] The air pressure balance assembly 120 consists of two main parts: an air pressure balance pipe 1201 and an air pressure balance valve 1202. One end of the air pressure balance pipe 1201 is closely connected to the feeding bin 10, and the other end is connected to the throwing pipe 20. Such a design enables the air pressure balance pipe 1201 to form an effective air pressure transmission channel between the feeding bin 10 and the throwing pipe 20.

[0075] In order to further adjust and control the air pressure balance, an 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 remains at an ideal level. Specifically, the function of the air pressure balance valve 1202 is to prevent the air pressure inside the throwing pipe 20 from being too high due to the air compressor delivering to the throwing pipe 20, causing the air pressure inside the throwing pipe 20 to be 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. By properly adjusting the air pressure balance valve 1202, a proper 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 materials.

[0076] This design not only improves the working efficiency of the feeder, but also ensures the stability and reliability of the entire feeding process. Through the adjustment of the air pressure balance component 120, the problem of material blockage or waste caused by excessively high or low air pressure can be effectively avoided, thereby ensuring that the feed can be thrown to the designated location evenly and continuously. In general, the introduction of the air pressure balance component 120 makes the feeder more flexible and efficient during operation, and improves the performance of the entire feed conveying system.

[0077] Optionally, sensors for monitoring and adjusting air pressure may also be provided in the feeding bin 10. These sensors can detect the air pressure state in the feeding bin 10 in real time and transmit the data to the control system. The control system automatically adjusts the opening of the air pressure balance valve 1202 in cooperation with the electrical control valve according to the data provided by the sensor to maintain the stability of the air pressure. This automatic adjustment mechanism not only improves the accuracy of the operation, but also reduces the need for manual intervention, making the entire feeding process more intelligent and automated.

[0078] In addition, to further improve the performance and reliability of the feeder, a fault diagnosis system is also added to the design. The system can monitor the operating status of the feeder in real time. Once an abnormal situation is detected, such as air pressure imbalance, material blockage or mechanical failure, the system will immediately issue an alarm and provide corresponding fault information and solutions. This not only helps to troubleshoot in time, but also prevents potential problems and ensures the long-term stable operation of the feeder.

[0079] The present invention also provides a working method of a feeder 1, and the working method uses the feeder. The specific structure of the feeder refers to the above embodiment. Since the working method adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0080] A working method of a feeding machine 1 is applied to the feeding machine as above, wherein the feeding machine further comprises a first sensor 70, a second sensor 80, a third sensor 90 and a pressure sensor 110, and the electric 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 comprises the following steps: The target feeding weight of the feeding bin 10 is set, and the pressure sensor 110 is controlled to detect the real-time weight of the feeding bin 10; Control to open the first switch valve 30 and start the driving member 40; Receive the real-time weight of the pressure sensor 110, and compare it with the target feeding weight; 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 be closed; receiving detection data from the first sensor 70; If the first sensor 70 detects that no material passes through, the second switch valve 53 is controlled to open and the driving member 40 is started; receiving detection data from the second sensor 80; If the second sensor 80 detects that the cleaning ball 52 passes through, the second switch valve 53 is controlled to be closed; receiving detection data from the third sensor 90; If the third sensor 90 detects that the cleaning ball 52 passes through, the driving member 40 is controlled to be closed and the third switch valve 54 is opened; The third switch valve 54 is controlled to be closed.

[0081] The working method of the feeding machine is as follows: when it is necessary to feed, the target feeding weight of the feeding bin 10 is set to the electronic control device 60, which is converted into the analog quantity of the pressure sensor 110. The electronic control device 60 receives the data of the pressure sensor 110, converts it into the actual weight inside the feeding bin 10, and continuously monitors the data of the pressure sensor 110. The electronic control device 60 controls the opening of the first switch valve 30 and the driving member 40, and the second switch valve 53 and the third switch valve 54 remain closed. The feed falls from the feeding bin 10 into the throwing pipe 20, and is thrown out along the discharge port 12 of the throwing pipe by the driving member 40. When the data of the monitoring pressure sensor 110 reaches the preset target feeding weight, the first switch valve 30 is controlled to be closed. The electronic control device 60 continuously monitors the signal of the first sensor 70. When the electronic control device 60 receives the signal of the first sensor 70 and no material passes through, it indicates that the material unloading is completed.

[0082] When the pipeline needs to be cleaned after the feed is put in, the cleaning ball 52 is placed in the cleaning section 511 of the cleaning pipeline 51 in advance, 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, the third switch valve 54 remains closed, and the cleaning ball 52 falls from the cleaning section 511 into the throwing pipeline 20. The electronic control device 60 continuously monitors the signal of the second sensor 80. When the electronic control device 60 receives the passing signal of the second sensor 80, it indicates that the lowering of the cleaning ball 52 is completed. The cleaning ball 52 is driven by the driving member 40 to move along the throwing pipeline, and the residual feed is pushed by the cleaning ball 52 to be thrown out along the discharge port 12 of the throwing pipeline. The electronic control device 60 continuously monitors the signal of the third sensor 90. When the electronic control device 60 receives the passing signal of the second sensor 80, it indicates that the cleaning ball 52 has reached the outlet of the throwing pipeline 20, indicating that the cleaning of the cleaning ball 52 is completed.

[0083] 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 drive member 40, and opens the third switch valve 54. The cleaning ball 52 falls from the throwing pipeline 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.

[0084] Furthermore, in another embodiment, the feeder further includes an air pressure balance component 120, and the air pressure balance component 120 includes an air pressure balance pipe 1201 and an air pressure balance valve 1202. Between step 1 and step 2, an air pressure adjustment step of the feed bin 10 is added: according to the size and amount of the material particles, the air pressure balance valve 1202 is adjusted to add an appropriate amount of air to the inside of the feed bin 10, so that the air pressure inside the feed bin 10 is relatively balanced with the external air pressure.

[0085] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
