Technical Field

The utility model relates to the field of screening of sorting machines, in particular to a screening box for a sorting machine.

Background

The sieve case of sorter among the prior art, its structure is mostly, and the outside is formed by the steel sheet concatenation, and the inboard sets up the cross baffle, divides into four bibliographic categories with the cavity of sieve case, and four sieve plates are placed on four cavity upper portions, and four supply-air outlets are seted up in every cavity outside. The external air supply enters the cavity and then goes upwards along the inner side rib plate, passes through the sieve mesh of the sieve plate and the materials on the sieve plate and then is discharged from the air induction port or the air outlet, and the materials are sorted under the dual actions of the vibration force and the wind power of the driving mechanism. Referring to fig. 1, an external blower sends wind power into an air inlet box 13 through an air inlet 5, the air inlet 5 is formed by welding a flange and a circular tube, after the external air enters the air inlet box 13, the external air is folded from the horizontal direction to the vertical direction under the shunting guiding action of an air inlet box partition plate 14 inside the air inlet box 13, enters the lower part of a screen box body 2 through a soft connecting piece 12, then passes through screen holes of a screen plate 3, and is subjected to wind power screening on materials scattered on the screen plate 3 and the materials falling from the upper part of the screen plate 3, and light materials are discharged from an air inlet or an air outlet under the action of the wind power.
