[0039] More specifically, the power assembly 5 includes a large permanent magnet 5.1 and a vibration coil 5.2. The large permanent magnet 5.1 is fixedly installed in the magnetic slot 3.1.1, and the vibration coil 5.2 is fixedly installed in the coil slot 2.2.

[0040] Furthermore, by pouring the material into the screening frame 3.1 and the screening mesh plate 3.2, the vibration coil 5.2 is started, and the vibration coil 5.2 continuously switches the positive and negative poles of the power supply, so that the large permanent magnet 5.1 moves closer to or away from the vibration coil 5.2, and the large permanent magnet 5.1 pushes the screening frame 3.1 and the screening mesh plate 3.2 to swing back and forth, and the material is screened through the screening mesh plate 3.2.

[0043] The small permanent magnet 4.10 is moving back and forth, and during the back and forth movement, the height position of the small permanent magnet 4.10 gradually increases.

[0044] The small permanent magnet 4.10 moves back and forth at the three rows of induction coils 4.15, and the position of the small permanent magnet 4.10 at the three rows of induction coils 4.15 is constantly changing, resulting in that the position of each row of induction coils 4.15 is different from that of the small permanent magnet 4.10. Some of the three rows of induction coils 4.15 are close to or far from the magnetic field of the small permanent magnet 4.10. The magnetic field driven by the moving small permanent magnet 4.10 cuts the induction coil 4.15, and then the electric signal generated by the induction coil 4.15 has different values ​​of the electric signals of the three rows of induction coils 4.15, and the changes in the values ​​are different. Through the size of the electric signal values ​​of the three rows of induction coils 4.15, and in conjunction with the back and forth swinging of the screening frame 3.1 and the screening mesh plate 3.2, the reduction of the material in the screening frame 3.1 and the screening mesh plate 3.2 can be detected, and the amount of material unloading can be judged by the value of the electric signal.

[0045] The speed of the large permanent magnet 5.1 and the vibration coil 5.2 swinging back and forth can be controlled by the electrical signals of the small permanent magnet 4.10 and the three rows of induction coils 4.15, so as to adjust the amount of material being discharged.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
