The bushing spring is characterized in that a spring outer pipe is solidified outside the rubber spring, a spring inner pipe is solidified in an inner hole of the rubber spring, and a connecting flange connected with the bottom of the sieve bend is welded at the upper end of the spring inner pipe.
The number of the electro-hydraulic push rods is two, and one is arranged on each of two sides of the angle adjusting seat. The number of the angle supporting plates is two, and two sides of the angle adjusting seat are respectively provided with one; 3-6 holes on the angle supporting plate correspond to the arc-shaped screen, and the adjusting angle is 30-52 degrees.
The beneficial effects of the utility model are that, adopt the inclination convenient and fast of electricity liquid push rod adjustment sieve bend, when the inclination of needs adjustment sieve bend, at first break off the grafting of angle backup pad and base round pin axle, start the angle adjustment seat that electricity liquid push rod promotes and be connected with the sieve bend, can make sieve bend and angle adjustment seat rotatory around the rotation axis, realize the adjustment to its angle. After the angle adjustment is in place, the corresponding hole in the angle supporting plate is inserted into the pin shaft on the base, so that the inclination angle of the sieve box of the arc-shaped sieve is positioned. When the feeding end of the sieve surface of the sieve bend is abraded, the bolt of the clamping plate on the bushing spring fixing sleeve is loosened, and the bushing spring is released from being fixed. And rotating the sieve bend connected with the bushing spring to rotate the sieve bend and the bushing spring by 180 degrees, and then clamping the bushing spring fixing sleeve. The conversion of the feeding end and the discharging end of the sieve bend is realized, and the service life of the sieve surface is prolonged. The vibrating screen has the characteristics of simple structure, convenience in adjustment and accuracy in positioning, and is suitable for vibrating screens with the inclination angles of the screen boxes needing to be adjusted.
