After the apple snails move, the two rotating plates are reset under the elastic force of the spring. At the same time, the rotating plate can only rotate on one side under the action of the spring, which can avoid the apple snails from climbing out of the trapping assembly.

[0020] The application utilizes the counting alarm assembly to count the number of apple snails during the trapping process, when the number is large, the counting alarm assembly informs the management personnel to clean the apple snails through the alarm mode, when the apple snails continue to fall from the connecting pipe, the apple snails will contact the counting plate, the gravity of the falling apple snails makes the counting plate rotate under force, when the counting plate rotates under force, the counter records the number of trapped apple snails through the transmission of the connecting shaft, at the same time, the alarm and the counter are connected through the electric signal, when the value on the counter reaches the preset value, the counter connects the alarm and the power supply through the electric signal, the alarm performs the sound and light alarm to inform the management personnel to clean the apple snails.

[0021] The application utilizes the extrusion assembly to clean the excessive apple snails, when the apple snails are excessive, the management personnel informed by the alarm connects the hydraulic cylinder and the power supply to make the hydraulic cylinder drive the pressing plate to extrude the apple snails in the storage ball net, which is helpful for the management personnel to clean the apple snails.

[0052] The hinged seat 14 is provided with two hinged seats 14, and the two hinged seats 14 cooperate with each other to help the rotating plate 15 to rotate under stress.

[0053] The rotating shaft 16 is cylindrical, and rotates under stress.

[0054] Further, after the apple snails fall into the inverted conical groove 7, the apple snails enter the trapping assembly from the inverted conical groove 7, and the trapping assembly helps the apple snails to enter the discharge bin 25, and the apple snails cannot climb out of the discharge bin 25, so as to achieve the purpose of trapping, when the apple snails enter the connecting pipe 13, the apple snails will contact the rotating plate 15, and the rotating plate 15 rotates under stress, after the rotating plate 15 rotates, a gap is formed between the two rotating plates 15, which helps the apple snails to continue to move from the gap between the two rotating plates 15, and after the apple snails move, the two rotating plates 15 are reset under the elastic force of the spring 17, and the rotating plate 15 can only rotate on one side under the action of the spring 17, which can prevent the apple snails from climbing out of the trapping assembly.

[0081] The apple snails enter the connecting pipe 13 from the inverted conical groove 7, the apple snails contact the rotating plate 15 after sliding, the apple snails extrude the rotating plate 15, the rotating plate 15 is stressed to rotate, the rotating shaft 16 rotates in the direction of the rotating plate 15, and the spring 17 is stressed to contract, at this time, a gap is generated between the two rotating plates 15, the apple snails continue to move through the gap between the two rotating plates 15, when the apple snails move, the rotating plate 15 loses external force, the rotating plate 15 is reset under the elastic force of the spring 17, so that the rotating plate 15 returns to the initial position.

[0082] When the apple snails continue to fall from the connecting pipe 13, the apple snails will contact the counting plate 19, and the gravity of the falling apple snails will make the counting plate 19 rotate under stress. When the counting plate 19 rotates under stress, the counter 21 will be driven to rotate through the transmission of the connecting shaft 20. When the counting plate 19 rotates under stress once, the counter 20 will display the number one. When the counting plate 19 rotates multiple times, the number displayed on the counter 20 will also increase sequentially, thereby recording the number of captured apple snails. At the same time, the warning device 23 and the counter 21 are connected through electrical signals. When the value on the counter 21 reaches the preset value, the counter 20 will send an electrical signal to the receiving end in the warning device 23. After the warning device 23 receives the signal, the warning device 23 is electrically connected with the power supply, and the warning light 24 on the warning device 23 is turned on to sound and light alarm, thereby notifying the manager to clean the apple snails.

[0083] When the manager hears or sees the sound and light alarm of the warning device 23, the manager will remotely control the hydraulic cylinder 34 to be electrically connected with the power supply. After the hydraulic cylinder 34 is electrically connected with the power supply, the hydraulic cylinder 34 drives the telescopic end to move, and the telescopic end drives the pressing plate 35 to move. The pressing plate 35 extrudes the storage ball net 28, and the storage ball net 28 extrudes a large number of apple snails under stress, thereby centrally processing the apple snails.

[0084] After the excess apple snails in the water are processed, the manager monitors the rice fields on the water surface that have not been captured or have apple snail eggs. The monitor 4 is electrically connected with the built-in power supply and is used after that. The monitor 4 collects the picture of the initial angle of the rice field. After that, the motor 5 is electrically connected with the power supply, the motor 5 drives the rotating shaft to rotate, and the monitor 4 rotates in the direction of the rotating shaft. After that, the monitor 4 collects the picture of the other angle of the rice field. After the monitor 4 rotates one circle, the monitor 4 collects the pictures of the rice fields around. The manager can identify the number of apple snail eggs through the collected pictures. When the number of apple snails is large, the apple snails need to be captured and processed by using the capturing device. If the number of apple snails is small, the apple snails do not need to be captured by using the capturing device.
