The RFID reading module 23 is installed on the lower end of the top plate 22. The central control unit is installed on the upper end of the top plate 22. The central control unit is used to receive RFID identification information and weight data, and to process and store the data. The intelligent weighing module is installed at the lower end of the base plate; the intelligent weighing module is used to collect the weight data of the sheep passing through. The automatic grouping gate device is installed inside the frame 21; the automatic grouping gate device is used to push the front door 212 or the rear door 211 to open.

[0015] In one embodiment of this utility model, the central control unit includes a control cabinet 24; the control cabinet 24 is installed on the top of the top plate 22; the control cabinet 24 is electrically connected to the RFID reading module 23, the intelligent weighing module and the automatic grouping gate device respectively; the control cabinet 24 is used to receive RFID identity information and weight data, and to process and store the data; the control cabinet 24 can generate grouping control commands according to the preset grouping logic.

[0016] In one embodiment of this utility model, the intelligent weighing module includes a weighing sensor 251; the bottom end of the frame 21 is fixedly connected to the mounting plate 25; the weighing sensor 251 is fixedly mounted on the upper end of the mounting plate 25; a load-bearing plate 252 is provided on the upper end of the weighing sensor 251; the upper end surface of the weighing sensor 251 is in contact with the lower end surface of the load-bearing plate 252; and the weighing sensor 251 is electrically connected to an external weighing display instrument.

[0017] In one embodiment of this utility model, the automatic grouping gate device includes an electric push rod assembly; the electric push rod assembly is located between the frame 21 and the top plate 22; the electric push rod assembly is fixedly installed on the upper end of the frame 21; the electric push rod assembly includes a first electric push rod 26 and a second electric push rod 27; the first electric push rod 26 is connected to the front door 212 through a connecting unit; the second electric push rod 27 is connected to the rear door through a connecting unit. In one embodiment of this utility model, the connecting unit includes a hinge plate 281; the middle part of the hinge plate 281 is rotatably connected to the frame 21; one end of the hinge plate 281 is connected to the electric push rod assembly through a connecting plate 28; the end of the hinge plate 281 near the front door 212 away from the connecting plate 28 is rotatably connected to the front door 212; the end of the hinge plate 281 near the rear door 211 away from the connecting plate 28 is rotatably connected to the rear door 211.

[0018] In one embodiment of this utility model, the automatic grouping gate device further includes a pneumatic push rod 11; both sides of the side rail 1 are rotatably connected to a partition gate 12; the pneumatic push rod 11 is rotatably mounted on the upper end of the side rail 1; an arc-shaped plate 13 is provided between the partition gate 12 and the pneumatic push rod 11; one end of the arc-shaped plate 13 is rotatably connected to the pneumatic push rod 11, and the other end is fixedly connected to the partition gate 12.

[0019] In one embodiment of this utility model, the partition gate 12 is composed of side bars 121 and several horizontal bars 122. Each horizontal bar 122 is composed of support bars 123 and elastic bars 124. There are four support bars 123. Two support bars 123 are fixedly connected to the upper and lower sides of each elastic bar 124. The distance between two support bars 123 on the same side of the elastic bar 124 is 2 cm. The support bars 123 are rotatably connected to the side bars 121. The support bars 123 rotate horizontally but cannot rotate vertically.

[0020] During operation, an external human-machine interface terminal connected to the central control unit is installed. The human-machine interface terminal includes a touch screen and operation buttons, used to input grouping strategies, view historical data, monitor system operation status, and set parameters. Since the weighing sensor 251 is electrically connected to an external weighing display instrument, and the weighing display instrument is electrically connected to the touch screen, the parameters of the weighing sensor 251 can be directly controlled to zero through the human-machine interface terminal. Then, the user controls the first electric push rod 26 near the front door 212 to operate, so that the first electric push rod 26 near the front door 212 pushes the hinge plate 281 to rotate away from the front door 212 through the connecting plate 28, so that the end of the hinge plate 281 away from the connecting plate 28 rotates towards the front door 212, so that the end of the hinge plate 281 away from the front door 212 pushes the front door 212 to open outward.

[0021] After the front door 212 is opened, the user drives the sheep to be tested into the guide channel inside the frame 21 through the opened front door 212. Then, the first electric push rod 26 retracts and pulls the front door 212 to close. At this time, the sheep is located at the upper end of the load-bearing plate 252, so that the load-bearing plate 252 bears the weight of the sheep. Under the push of the sheep's gravity, the load-bearing plate 252 squeezes the weighing sensor 251 below, so that the weighing sensor 251 weighs the sheep at the upper end of the base plate. The weight data obtained from the sheep's weighing is directly transmitted to the weighing display instrument for easy observation by the operator. The measured weight data is also transmitted to the control cabinet 24 for data processing and storage.

[0022] Since the RFID reading module 23 is installed at the lower end of the top plate 22 and the sheep have electronic ear tags on their ears, when the sheep enter the frame 21, the RFID reading module 23 installed at the lower end of the top plate 22 can automatically identify the electronic ear tag information of the sheep and transmit the identified electronic ear tag information of the sheep to the control cabinet 24. The control cabinet 24 then processes and stores the received RFID identity information and weight data, and generates group control instructions according to the preset grouping logic (such as weight range, individual ID, etc.).

[0023] After generating the grouping control command, the control cabinet 24 directly controls the second electric push rod 27 near the rear door 211 to push the rear door 211 open. At this time, the sheep enter the side pen 1 through the guide channel from the opened rear door 211. Subsequently, according to the grouping control command generated by the control cabinet 24, the pneumatic push rods 11 on the left or right side are controlled to push the left or right pen gate 12 open. For example, if it is necessary to group sheep by weight range, that is, the sheep pen near the left pen gate 12 needs to be used by larger sheep, and the sheep pen near the right pen gate 12 needs to be used by smaller sheep. When lambs enter, the control cabinet 24 generates a grouping control command based on the measured weight when the back door 211 is opened. When the measured weight of a large lamb is found, the control cabinet 24 transmits an electrical signal to the pneumatic push rod 11 near the left partition door 12, causing the pneumatic push rod 11 to extend and push the arc plate 13 to rotate. This causes the arc plate 13 to drive the left partition door 12, which is fixed to the left side, to rotate and open. At this time, the lambs that have left the frame can only enter the sheep pen where the large lambs are located through the left partition door 12, thus realizing the intelligent grouping of the sheep.

[0024] The pen gate 12 consists of side bars 121 and crossbars 122. The crossbars 122 are composed of support bars 123 and elastic bars 124. The support bars 123 are rotatably connected to the side bars 121 and can only rotate horizontally, not vertically. The two support bars on the same side of the elastic bars 124 are 2 cm apart. When sheep are separated, they usually push and shove each other. Before the pen gate 12 is opened, the sheep will only touch the pen gate 12. Since there are many sheep, they are difficult to control and will inevitably squeeze the pen gate 12, which may cause the pen gate 12 to deform. Due to the design of the crossbars 122, when the sheep touch the crossbars 122, they will deform horizontally. And due to the restriction of the support bars 123, the crossbars can only deform horizontally and will not deform vertically. This will prevent the sheep from being stressed and ramming the pen gate to escape after entering.

[0025] This invention integrates three major functions: RFID identification, weighing, and grouping. It enables automatic collection of individual sheep information, accurate acquisition of weight data, and automatic grouping on demand, greatly reducing manual intervention. At the same time, the automatic grouping function can quickly classify sheep according to multi-dimensional rules such as weight and production stage. This not only ensures that weight data corresponds one-to-one with specific individuals, but also provides reliable data support for precision feeding, disease prevention and control, and breeding selection, significantly improving the efficiency of sheep farm management. Therefore, it is suitable for large-scale and intelligent sheep production and reduces labor costs.
