The invention relates to a complex excitation
system for a resonant type vibrating screen and discloses a
resonance screen excitation
system. The
resonance screen excitation
system consists of excitation ranks, an excitation connection frame and four
resonance springs arranged at four corners of the lower portion of the excitation connection frame; by means of the resonance screen excitation system, the problem that existing complex excitation systems for resonant type vibrating screens are poor in reliability is solved; the structure is simple, and a spring transmission excitation force which is parallel to a screen
machine vibration direction is used, so that the problem of serious abrasion of the resonant type spring is solved, the
fault rate of the complex excitation system is greatly reduced, and normal operation of the resonant screen is guaranteed; if the resonant screen is used as a device for arranging and tensioning a support net, hook plates and fixing bolts used for connecting a screen frame and the resonant screen to arrange and tension the support net are reduced, vibration
mass of the screen box combination is reduced,
workload of the spring bearing the screen box combination is reduced, service life of the spring is prolonged, meanwhile, fault hidden danger brought by fixed bolt looseness caused by vibration during usage is fundamentally eliminated, and the
fault rate of the vibration screen is further reduced.
