Title:
LARGE SYNCHRONIZING STATICALLY INDETERMINATE BEAM EXCITATION VIBRATING SCREEN
Document Type and Number:
WIPO Patent Application WO/2014/176796
Kind Code:
A1
Abstract:
A large synchronizing statically indeterminate beam excitation vibrating screen, comprising a screen box, a supporting spring set, a spring base, a motor mount frame, a tire shaft coupling, and an electric motor; a statically indeterminate beam excitation body is provided on the screen box; the statically indeterminate beam excitation body is provided with at least one synchronizing eccentric block exciter assembly and two self-synchronizing eccentric block exciter assemblies; the self-synchronizing eccentric block exciter assembly comprises a self-synchronizing drive shaft fixed on the side panel of the screen box via the shaft support base self-synchronizing drive shaft is provided with a self-synchronizing eccentric block symmetrically fixed on the side panel of the screen box; the self-synchronizing drive shaft, near one side of the electric motor, of the self-synchronizing eccentric block exciter assembly is, via the tire shaft coupling, connected to a decelerator; the decelerator is connected, via the drive belt, to the electric motor. The structure is driven by means of synchronized gears at the center part of the statically indeterminate beam body, achieving synchronized excitation of the vibrating screen. The stiffness of the structure is increased and its center of gravity is lowered, thereby improving the quality of the structure of an exciting body in a vibrating screen. The weight of the vibrating screen is reduced, the structure of the screen body is simplified, and processing techniques for the screen are simple.
