Abstract

The invention relates to a four-short shock excitation motor linear vibrating screen with torsion springs coupling. The four-short shock excitation motor linear vibrating screen is composed of a feed hopper, a first shock excitation motor, a shield, a second shock excitation motor, a third shock excitation motor, a motor base, a fourth shock excitation motor, a screen box, an isolation spring, a base, a second coupling eccentric block, the first torsion spring, a first coupling eccentric block, a fourth coupling eccentric block, the second torsion spring and a third coupling eccentric block. The four identical shock excitation motors are installed on the motor base coaxially in pairs, and the torsion springs connect the two axial shock excitation motors in a coupled mode and relieve and absorb start impact of the two shock excitation motors to achieve zero-phase synchronization of the two shock excitation motors. The two pairs of shock excitation motors rotate in the opposite directions at equal speed and generate shock excitation force to achieve linear motion of the vibrating screen. After operation is stable, the two shock excitation motors connected in a coupled mode only need to be powered on alternatively. Shock excitation force of the shock excitation motors can be brought into full play to achieve large amplitude of the vibrating screen, and the four-short shock excitation motor linear vibrating screen is low in energy consumption, simple in structure, easy to install and maintain and small in noise and occupied area.
