Patent ID: 8074805

Claim:
A vibrating screen apparatus with duplex statically indeterminate mesh beam excitation body and plate type combined bearing beam, the vibrating screen apparatus comprising: a screen box ( 1 ) including a side plate ( 3 ); a screen plate ( 13 ) the screen box ( 1 ); an elastic bearing body ( 7 ) supporting the screen box ( 1 ); a statically indeterminate mesh beam unit fixed to the side plate ( 3 ); motors ( 15 ); tire-type flexible couplings ( 14 ); a plate type statically indeterminate combined bearing beam ( 12 ) fixed to the side plate ( 3 ) and arranged under the screen plate ( 13 ); rectangular close beams ( 2 , 8 ) connected to the combined bearing beam ( 12 ) and arranged at a discharging side of the screen box ( 1 ) and a feeding side of the screen box 1 ,; and a plurality of Y-shaped statically indeterminate combined reinforcing beams ( 5 ) arranged on the side plate ( 3 ) of the screen box at locations spaced apart from the statically indeterminate mesh beam unit; wherein the statically indeterminate mesh beam unit comprises a duplex statically indeterminate mesh beam excitation body ( 11 ) including a plurality of mesh beams ( 21 ) linked via duplex statically indeterminate supporting plates ( 22 ) to a statically indeterminate connecting plate ( 4 ) and the side plate ( 3 ) of the screen box so as to form a beam system; and wherein the vibrating screen apparatus further comprises a vibration exciter ( 10 ) connected with the statically indeterminate mesh beam excitation body ( 11 ) and comprising eight sets of vibration exciters horizontally aligned in pairs, linked via universal couplings ( 9 ) and connected to motors ( 15 ) through the tire-type flexible couplings ( 14 ).
