The invention discloses an amplitude adjusting device of a flip-flow screen sectional type walking beam. The amplitude adjusting device comprises an upper supporting base, a lower supporting base, rubber assemblies, walking beam connection plates and pretightening force adjustors. The upper supporting base and the lower supporting base are connected with a screen box side plate through ring-grooved lock bolts. The rubber assemblies comprise upper connection plates, shear rubber, lower connection plates and wear-resisting inserting sleeves. The upper connection plates make contact with the pretightening force adjusters. The upper connection plates, the lower connection plates and the shear rubber are fixedly connected through powerful glue. The lower connection plates are connected with the walking beam connection plates. The wear-resisting inserting sleeves are fixedly connected with the connection plates. The pretightening force adjusters are composed of fixed limiting stoppers, anti-loosening elastic pads and locking nuts. The fixed limiting stoppers are located among the upper supporting bases, the lower supporting bases and the connection plates. The locking nuts are arranged above the anti-loosening elastic pads. By means of the pretightening force adjusters, the pretightening force of the shear rubber can be independently adjusted, and the amplitude adjusting device can broaden the amplitude range of the walking beam and has the advantages of being high in adaptability, easy to adjust, convenient to mount and the like.
Description
technical field [0001] The invention relates to the field of vibrating screening equipment, in particular to a segmental movable beam amplitude adjustment device for a relaxation screen, which can realize segmental independent adjustment of the amplitude of a movable beam on a relaxation screen. Background technique [0002] The relaxation screen is a new type of screening machine developed from the traditional circular vibrating screen in the early 1980s. The screen is made of stretchable polyurethane rubber material. When working, the screen is alternately tensioned and loosened to make the material move forward and bounce, which can prevent the material from sticking to the screen and blocking the screen holes. At the same time, due to the use of flexible sieve plates, the projectile acceleration can reach 30-50 times the acceleration of gravity, and the maximum amplitude of the sieve plate can reach 40mm, so the sieve holes are not only not easy to be blocked, but also t...
