Abstract: Embodiments of the invention provide a synchronous statically indeterminate mesh-beam excitation large-scale vibrating screen, including a screen box, a support spring group, a spring base, a motor mount, a tire coupling, and a motor, wherein, a statically indeterminate mesh-beam excitation body is arranged on the screen box, and the statically indeterminate mesh-beam excitation body has at least one synchronous eccentric block vibration exciter group and two self-synchronous eccentric block vibration exciter groups in it; each self-synchronous eccentric block vibration exciter group includes a self-synchronous transmission shaft fixed to the side plates of the screen box via a bearing chock, and self-synchronous eccentric blocks fixed to the side plates of the screen box in symmetry are arranged on the self-synchronous transmission shaft; the self-synchronous transmission shaft of the self-synchronous eccentric block vibration exciter group at the side of the motor is connected with a reducer via the tire co

Abstract: An extra-large vibrating screen with duplex statically indeterminate mesh beam excitation body and plate type combined bearing beam comprises plate type flat and rigid statically indeterminate combined bearing beam (12) arranged in a screen box (1), a plurality of Y-shaped statically indeterminate combined reinforcing beams (5) arranged on the side plates (3) of the screen box alternately, duplex statically indeterminate supporting plates (22) linking a plurality of mesh beams (21) to the statically indeterminate connecting plate (4) and the side plate (3) so as to form a container made of a beam system, the vibration exciters (10) in the statically indeterminate mesh beam unit comprising eight sets of vibration exciters, which are aligned in pair horizontally and linked together through universal couplings (9), and connected to the duplex statically indeterminate mesh beam excitation body (11) to form a highly rigid integral vibrating assembly.

Abstract: An elastic sieving method and corresponding large-sized elastic vibration screen. The present invention utilizes a screening surface and a separate sieving machine. A screen mat located on the sieve box is connected to multiple small rectangular screens. While the machine is vibrating, the resonation of screen rods located on the screen mat connected by small rectangular screens are initiated to screen the material and to cause the vibration of the whole vibration screen and realize the conveyance and lamination of materials. Because the screening surface is in a state of resonance, the vibration strength is strong enough to prevent the screen meshes from becoming plugged, allowing for high sieving efficiency. A bearing in the sieving mechanism is installed with a vibration damping ring, placing the bearing in a resonant state, allowing for a low dynamic stress level, which satisfies the process requirement for large-sized vibration screen excitation units with a screening surface as wide as 4800 mm.
