Screen plate structure capable of improving screening efficiency of vibrating screen

The sieve plate structure capable of improving the screening efficiency of the vibrating screen comprises a sieve plate installation body, the sieve plate installation body comprises a plurality of sieve plate single bodies, each sieve plate single body is made in a pouring mode, each sieve plate single body comprises a guide distribution block and an end cover, and a sieve net is fixed to the inner side of each sieve plate single body. The guide distribution blocks are of triangular prism-shaped cavity structures and are symmetrically fixed to the two sides of the sieve plate single bodies, the end covers are detachably connected with the distribution blocks, the outer surfaces of the end covers and the distribution blocks are flush, vibration structures are arranged in the guide distribution blocks, and the inner sides of the end covers are fixedly connected with vertically-arranged air cylinders. The screening efficiency of the vibrating screen is improved, it is ensured that all materials are screened thr
