[0021] Working principle:

[0022] The material to be screened enters the distribution box 7 through the feed pipe 6, and the material in the feed pipe 6 is broken up by the punching plate 71 and then evenly scattered into the distribution box 7 through the distribution holes 711 and the arc grooves 712. The distribution box 7 is divided into multiple distribution channels by the distribution plate 72. The material in the distribution box 7 enters the distribution channel and falls onto the distribution plate 72. The material diffuses along the width direction of the screen 5 along the distribution plate 72 and falls into the laminated screen box 1. The laminated screen box 1 and the screen 5 are driven by the driving mechanism 4 to make a linear reciprocating motion, thereby realizing the screening of the material, and the screened material is discharged through the discharge chute 8; the dust removal pipe 9 is connected to the external dust removal equipment, and the inside of the laminated screen box 1 is dusted through the dust removal pipe 9 on the laminated screen box 1.

[0023] Furthermore, the cloth box 7 is an isosceles trapezoidal box structure, and the cloth plates 72 on the left side of the cloth box 7 are parallel to the left slanted wall, and the cloth plates 72 on the right side of the cloth box 7 are parallel to the right slanted wall; the cloth box 7 is an isosceles trapezoidal box structure, which is conducive to the diffusion of materials in the width direction of the screen 5, and reduces the occupied area and processing cost of the cloth box 7.

[0024] Furthermore, a discharge pipe 81 is provided at the end of each of the discharge chutes 8, and the discharge pipes 81 of the discharge chutes 8 are staggered with respect to each other in the horizontal direction.

[0025] The distribution screen with a distribution device disclosed in the present embodiment, after the material enters the feed pipe 6, it is first broken up by the punching plate 71, and the broken up material enters the distribution box 7 and is evenly distributed by the distribution plates 72. The distribution plates 72 on the left and right sides of the distribution box 7 are symmetrically arranged and inclined in opposite directions. The distribution plates 72 on the left and right sides of the distribution box 7 are arranged in an "eight" shape, so that the material entering the laminated screen box 1 is evenly diffused along the width direction of the screen 5 and scattered into the laminated screen box 1. The distribution at the feed of the laminated screen box 1 is even, which improves the sorting accuracy and sorting efficiency of the distribution screen and increases the processing capacity of the distribution screen.
