The solenoid device m513 is electrified with the solenoid device q509, the solenoid device p515 is electrified with the solenoid device k511, the screen box 3 is suspended, the micro-current controllers 10 corresponding to the four electrified solenoid devices increase the input current, and the screen box 3 moves upwards; the microcurrent controller 10 corresponding to the four energized solenoid devices reduces the input current and the sieve box 3 moves downward, repeating this, to achieve a vertical screening result.

If the screening direction is mainly horizontal rotation and assisted vertical movement, the micro-current controller 10 correspondingly controls the current in the corresponding electromagnetic coil device according to the signal transmitted by the control system, wherein the micro-current controller 10 outputs the current according to the corresponding parameter requirement, the electromagnetic coil device e505 and the electromagnetic coil device b502 are electrified, the electromagnetic coil device g507 and the electromagnetic coil device d504 are electrified and then are powered off after being electrified for 0.5s, the electromagnetic coil device f506 and the electromagnetic coil device c503 are electrified, the electromagnetic coil device h508 and the electromagnetic coil device a501 are electrified and then are powered off after being electrified for 0.5s, and the operation is repeated, so that the screen box 3 can achieve the effect of clockwise rotation.
