[0002] In the field of large-scale pig breeding, in order to optimize growth performance, improve feed utilization efficiency and protect animal welfare, it is crucial to group feeding and precise feeding according to the differentiated nutritional needs and behavioral characteristics of different pig groups (such as young pigs and adult pigs, pigs at different growth stages or body conditions). The traditional mixed feeding mode is easy to cause strong adult pigs to compete for young pig feed, resulting in malnutrition and growth inhibition of young pigs, and even safety accidents such as adult pigs stepping and squeezing young pigs.
[0003] The existing technology mainly forms fixed partitions by physical isolation for grouping, and sets up independent fixed feeding troughs in each partition for feeding. However, the fixed partitions occupy a large amount of effective breeding space, limiting the activity range of pigs, especially when the pig group structure or activity area needs to be temporarily adjusted, it is rigid; secondly, the feeding process is usually independent of the spatial management of the pig group, and it is difficult to effectively prevent adult pigs and young pigs from contacting due to the proximity of the feeding trough to the partition boundary or management negligence during or immediately after feeding, and the safety of young pigs and the exclusivity of feed are difficult to guarantee; furthermore, the existing feeding control system is mostly independent of the partition management device, lacks linkage mechanism, and it is difficult to automatically trigger precise feeding for specific partitions according to the real-time spatial distribution state of the pig group (such as some area pigs being driven away or concentrated); and it is difficult to realize the dynamic switching of the activity area and the feeding area to avoid mutual interference.

[0013] As a further preferred, a terminal is arranged relative to the integrated controller, and the terminal is used to feedback and display the signals collected by the integrated controller.
[0014] The beneficial effects of the present application compared with the prior art are:
[0015] 1、The core of the device is to realize the real-time, alternating and intelligent adjustment of the first feeding area and the second feeding area by using the movement of the dynamic drive plate. When the drive plate moves to one area, the area shrinks, but the corresponding feeding channel is opened for feeding. At this time, adult pigs are constrained in a small area for eating, and physically isolated from the young pigs in the activity area, which fundamentally eliminates the damage behavior of adult pigs to young pigs during eating or activity, such as pushing, stepping and arching. Conversely, when the drive plate moves to the first feeding area, the young pigs are constrained in a small space for eating, and the activity area is provided for adult pigs to move, which also avoids the interference of young pigs to adult pigs or the potential threat of adult pigs activity to young pigs.
[0016] 2、The linkage control mechanism triggered by the movement of the drive plate ensures that the feeding behavior is accurately directed to the target pig group in the current constrained partition. When adult pigs are constrained for eating, only feeding channel b is opened, and feed is only fed into the trough of the second feeding area, and young pigs cannot access it; when young pigs are constrained for eating, only feeding channel a is opened, and feed is only fed into the trough of the first feeding area, and adult pigs cannot compete for it. This directional feeding under physical isolation completely solves the problem of strong and weak pigs competing for food, ensures that young pigs can obtain feed matching their needs (usually higher nutrient concentration and finer particle open feed or nursery feed), and adult pigs can obtain their fattening feed, realizing real differential nutrition precise supply.

DETAILED DESCRIPTION
[0020] The above and other embodiments and advantages of the present application are more fully described in conjunction with the accompanying drawings below. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.
[0021] In one embodiment, as shown in Figs. 1-2
[0022] The embodiment provides a multi-pig group differentiation feeding control device, which comprises an integrated controller 1 and a fence 2, and the integrated controller 1 comprises a first control unit 11 and a second control unit 12.
[0023] The fence 2 is provided with a first feeding area 21 and a second feeding area 22, and the fence 2 is provided with a feeding device 23 outside, one feeding channel a of the feeding device 23 is connected to the first feeding area 21, and a first electromagnetic valve 231 controlled by the first control unit 11 is arranged at the discharge end of the feeding channel a, and the other feeding channel b of the feeding device 23 is connected to the second feeding area 22, and a second electromagnetic valve 232 controlled by the second control unit 12 is arranged at the discharge end of the feeding channel b.
[0024] The fence 2 is provided with a driving plate 24 reciprocatingly moving between the first feeding area 21 and the second feeding area 22, by the directional movement of the driving plate 24 relative to the first feeding area 21, the first control unit 11 is triggered to open the first electromagnetic valve 231, so that the feeding channel a automatically feeds the trough in the first feeding area 21, and by the directional movement of the driving plate 24 relative to the second feeding area 22, the second control unit 12 is triggered to open the second electromagnetic valve 232, so that the feeding channel b automatically feeds the trough in the second feeding area 22.
[0025] The fence 2 serves as a carrier of the integrated controller 1, so that it is effectively controlled in use, and the differentiation feeding quality of the pig group is improved. First, the feeding area of the fence 2 is defined as the first feeding area 21 and the second feeding area 22, and a set of troughs is arranged in each of the first feeding area 21 and the second feeding area 22, for example, adult or ready-to-market pigs are kept in the second feeding area 22, and young pigs are kept in the first feeding area 21, so that they are classified and kept.
[0026] In addition, the middle part of the cavity bottom of the fence 2 is provided with an active area 26, the first feeding area 21 and the second feeding area 22 are located on the two sides of the active area 26, and the range of the active area 26 is adjusted in size with the position change of the driving plate 24 relative to the first feeding area 21 or the second feeding area 22.
[0027] The classification management is first reflected in the differential management: for example, the control unit in the integrated controller 1 controls the movement of the expelling plate 24 relative to the second feeding area 22, at this time, the enclosure area of the second feeding area 22 is temporarily reduced, and the enclosure area of the first feeding area 21 is temporarily increased, the area of the activity area 26 relative to the first feeding area 21 is increased, and the activity range of the piglets is large. Since the enclosure area of the second feeding area 22 is reduced at this time, the activity range of the adult pigs is small, and the adult pigs will not affect the piglets at this time, for example, the adult pigs will not push, step on or kick the piglets. Conversely, the control unit in the integrated controller 1 controls the movement of the expelling plate 24 relative to the first feeding area 21, at this time, the enclosure area of the second feeding area 22 is temporarily increased, and the enclosure area of the first feeding area 21 is temporarily reduced, the area of the activity area 26 relative to the second feeding area 22 is increased, and the activity range of the adult pigs is large. Since the enclosure area of the first feeding area 21 is reduced at this time, the activity range of the piglets is small, and the piglets will not disturb the adult pigs at this time, and the adult pigs will not have the above-mentioned harmful effects on the piglets when they are active. The second is reflected in the differential feeding; based on the above, when the expelling plate 24 moves relative to the second feeding area 22, it will move away from the first control unit 11 and approach the second control unit 12. The second control unit 12 sends a signal to the integrated controller 1, and the integrated controller 1 controls the second electromagnetic valve 232 to open (the first electromagnetic valve 231 is closed). At the same time, the feeding device 23 works, and automatically feeds the food trough in the second feeding area 22 through the feeding channel b. Since the enclosure area of the second feeding area 22 is reduced at this time, the adult pigs have little activity space at this time, and the food in the food trough of the second feeding area 22 is fed as the feeding time of the adult pigs at this time. At this time, the enclosure area of the first feeding area 21 is increased in the activity area 26, but the feeding channel a is closed, and the activity area 26 is used as the activity range of the piglets at this time. Conversely, when the expelling plate 24 moves relative to the first feeding area 21, it will move away from the second control unit 12 and approach the first control unit 11. The first control unit 11 sends a signal to the integrated controller 1, and the integrated controller 1 controls the first electromagnetic valve 231 to open (the second electromagnetic valve 232 is closed). The feeding device 23 works again, and automatically feeds the food trough in the first feeding area 21 through the feeding channel a. Since the enclosure area of the first feeding area 21 is reduced at this time, the piglets have little activity space at this time, and the food in the food trough of the first feeding area 21 is fed as the feeding time of the piglets at this time. The enclosure area of the second feeding area 22 is increased in the activity area 26, and the feeding channel b is closed. At this time, the activity area 26 is used as the activity range of the adult pigs.
[0028] In summary, the setting of the expelling plate 24 divides the fence 2 into the first feeding area 21 and the second feeding area 22 for differentiating the piglets and adult pigs; the expelling plate 24 moves between the first feeding area 21 and the second feeding area 22 through intelligent control, so that the range of the activity area 26 changes in size relative to the first feeding area 21 and the second feeding area 22, to realize the classification activities of the adult pigs and the piglets, avoid mutual interference between the old and the young, and prevent injury events; through the movement of the expelling plate 24 relative to the first feeding area 21 and the second feeding area 22 and the linkage control, when the first feeding area 21 is in the activity area, the second feeding area 22 is switched to be in the feeding; when the first feeding area 21 is in the feeding, the first feeding area 21 is switched to be the activity area.
[0029] In summary, the first feeding area 21 (such as the piglet area) and the second feeding area 22 (such as the adult pig area) are realized to be real-time, alternating, and intelligently adjusted. When the expelling plate 24 moves to one area, the area is reduced in size, but the corresponding feeding channel (such as the feeding channel b) is opened for linkage feeding. At this time, the adult pigs are constrained in a small area for eating, and the adult pigs are physically completely isolated from the piglets that are freely active in the activity area 26 (at this time, the activity area 26 is increased in size relative to the piglet area), which fundamentally eliminates the injury behaviors such as pushing, stepping, and arching of the adult pigs on the piglets during eating or activity. Conversely, when the expelling plate 24 moves to the first feeding area (the piglet area), the piglets are constrained in a small space for eating, and the activity area 26 is for the adult pigs to move, which also avoids the interference of the piglets on the adult pigs or the potential threat of the adult pigs' activity to the eating piglets.
[0030] In summary, through the linkage control mechanism triggered by the movement of the expelling plate 24, it is ensured that the feeding behavior is accurately directed to the target pig group in the current constrained partition. When the adult pigs are constrained for eating, only the feeding channel b is opened, and the feed is only fed into the trough of the second feeding area 22, and the piglets cannot access it; when the piglets are constrained for eating, only the feeding channel a is opened, and the feed is only fed into the trough of the first feeding area 21, and the adult pigs cannot compete for it. This directional feeding under physical isolation completely solves the problem of competition for food between strong and weak pigs, ensures that the piglets can obtain feed (usually open feed or nursery feed with higher nutrient concentration and finer particles) that matches their needs, and the adult pigs can obtain their fattening feed, realizing real differential and precise nutrition supply.
[0031] In another embodiment, the integrated controller 1 further comprises a UHF RFID reader installed on the entrance of the fence 2 for uniquely identifying and recognizing the piglets entering the first feeding area 21 and the second feeding area 22, and the integrated controller 1 further comprises a RFID electronic ear tag and a data acquisition module installed on the ear of the piglet. When the piglet enters the fence 2, the RFID electronic ear tag on the ear of the piglet senses the UHF RFID reader on the entrance, and the data of the piglet is recorded in the integrated controller 1 and transmitted to the terminal for storage and memory.
[0032] In another embodiment, the integrated controller 1 further comprises a dynamic decision module, and the first feeding area 21 is provided with a weighing unit 211 and a memory unit 212. The weighing unit 211 is at least one and is close to the discharge end of the feeding channel a, and the memory unit 212 is close to the weighing unit 211. The weighing unit 211 and the memory unit 212 are electrically connected to the data acquisition module, and the data acquisition module is electrically connected to the dynamic decision module. The weighing unit 211 provided in the first feeding area 21 allows the piglets to stand on the weighing unit 211 to complete the weight test when the piglets eat, and the data obtained after the test is transmitted to the data acquisition module and then transmitted to the terminal. When the value reaches the threshold value of the dynamic decision module, the dynamic decision module issues a command to the terminal, and according to the information of the piglet stored by the UHF RFID reader, the information of the piglet is highlighted on the terminal. At this time, the management personnel can easily classify the piglet into the second feeding area 22 for enclosure. The memory unit 212 assists in taking pictures of the piglet, which facilitates the management personnel to quickly distinguish during classification. The weighing unit 211 is arranged in the first feeding area 21, and since the first feeding area 21 is a separate area for enclosing piglets, the interference of adult pigs can be reduced.
[0033] In another embodiment, the feeding device 23 is provided with at least two silo units 235, and each of the discharge ports of the two silo units 235 is provided with a third electromagnetic valve 234, and the two discharge ports are jointly connected with a discharge pump 233, and the discharge pump 233 and the third electromagnetic valves 234 are electrically connected to the first control unit 11 and the second control unit 12. For example, when the feeding channel a automatically feeds the trough in the first feeding area 21, the third electromagnetic valve 234 of the discharge port of the corresponding silo unit 235 is opened, and the discharge pump 233 discharges to the feeding channel a, for example, when the feeding channel b automatically feeds the trough in the second feeding area 22, the third electromagnetic valve 234 of the discharge port of the corresponding silo unit 235 is opened, and the discharge pump 233 discharges to the feeding channel b, and the two silo units 235 are filled with different feeds, i.e., adult pig feed and piglet feed are respectively filled in the two silo units 235, so that the feeding purposes are different, and the purposes are different. The piglet feed is rich in protein and starch, and the main raw material is wheat and corn, and after processing, a proper amount of soybean or protein content of 46% or more soybean meal, concentrated protein, etc. are added. The crude protein and lysine content of the large pig feed is relatively high, and the first feeding area 21 and the second feeding area 22 are classified to provide feed, and the practicability is improved.
[0034] In another embodiment, the first control unit 11 includes a first distance sensor 111 arranged in the first feeding area 21, and the second control unit 12 includes a second distance sensor 121 arranged in the second feeding area 22, and the first distance sensor 111 and the second distance sensor 121 are respectively provided with matching sensing units on the two sides of the repelling plate 24, and the distance sensor can also be replaced with a proximity switch. For example, when the repelling plate 24 moves towards the first feeding area 21, the sensing unit on the side of the repelling plate 24 facing the first feeding area 21 forms a signal sensing with the first distance sensor 111, and when the distance reaches a threshold value, a feedback signal is fed back to the integrated controller 1, and the third electromagnetic valve 234 matched with the feeding channel a is controlled to be closed, and the feed provided to the trough in the first feeding area 21 is stopped; and as the sensing unit on the other side of the repelling plate 24 moves away from the second distance sensor 121, when the distance reaches a set threshold value, a feedback signal is fed back to the integrated controller 1, and the other third electromagnetic valve 234 matched with the feeding channel b is controlled to be opened, and the feed provided to the trough in the second feeding area 22 through the feeding channel b is started.
[0035] In another embodiment, the bottom of the fence 2 is provided with a screw rod 25, the drive-off plate 24 is drivingly connected to the screw rod 25, the first control unit 11 further comprises a servo motor 112 installed at one end of the screw rod 25, and the integrated controller 1 further comprises a timing module electrically connected to the servo motor 112. The servo motor 112 is fixed on the fence 2, and the power output shaft of the servo motor 112 is connected to the screw rod 25. For example, the timing module is set to 3 hours, and the servo motor 112 is automatically started to work, the screw rod 25 is driven by the servo motor 112 to rotate in the forward direction, the drive-off plate 24 is driven by the screw rod 25 to move towards the first feeding area 21, the enclosure area of the first feeding area 21 temporarily becomes smaller, and the enclosure area of the second feeding area 22 temporarily becomes larger. At this time, the piglets are restricted in the first feeding area 21 to feed the feed, and vice versa, the adult pigs are provided with more free space in the second feeding area 22. When the timing module is set to a 3-hour period, the servo motor 112 is automatically started to work again, the screw rod 25 is driven by the servo motor 112 to rotate in the reverse direction, the drive-off plate 24 is driven by the screw rod 25 to move in the reverse direction towards the second feeding area 22, the enclosure area of the first feeding area 21 temporarily becomes larger, and the enclosure area of the second feeding area 22 temporarily becomes smaller. At this time, the adult pigs are restricted in the second feeding area 22 to feed the feed, and vice versa, the piglets are provided with more free space in the first feeding area 21, and automatic control is realized.
