Abstract
The utility model relates to a vibration sieve body, which has a single-layer or multi-layer structure; wherein, each layer comprises side sieve body plates, crossbeams, supporting rods and sieve nets; wherein, the two side sieve body plates are respectively fixed on the left and the right sides of the sieve body; at the same layer, one or more crossbeams are arranged between the two side sieve body plates; the supporting rods are arranged on the crossbeams; one or more partition plates which are extended along the length direction of the sieve body are connected with the crossbeams; supporting plates are arranged on both sides of each partition plate; and the sieve nets are placed on the supporting plates and the supporting rods. The structure adopts the partition plates to divide the space between the two side sieve body plates along a width direction into a plurality of parts, and one of the sieve nets is placed in each space. The structure ensures that the width and weight of each sieve net can be greatly reduced, so that the labor intensity can be greatly reduced when the sieve nets are replaced, and moreover, the tensioning effect of the sieve nets is more obvious, so the service lives of the sieve nets can be effectively prolonged.
