Grain separating apparatus including step-like webs
First Claim
1. An apparatus for separating grain from a crop mat, comprising:
- a separating rotor operatively mounted in a rotor housing and having a rotor axis; and
a separating grate partly surrounding a lower part of the separating rotor and forming part of the rotor housing and including;
a plurality of frame portions;
a plurality of profiles operatively connected to the plurality of frame portions and extending parallel to the rotor axis; and
a plurality of step-like shaped webs operatively mounted between the plurality of profiles and the plurality of frame portions and transverse to the rotor axis forming a sieve for separating the grain from the crop mat.

Abstract
An apparatus for separating grain, kernel or cereal from harvested crop includes a separating rotor operatively mounted in a rotor housing and having a rotor axis, and a separating grate which partly surrounds the separating rotor and forms a lower part of the rotor housing. The separating grate includes a plurality of frame portions, profiles operatively connected to the plurality of frame portions and extending parallel to the rotor axis, and webs having apertures therein and bent in a step-like shape. The webs are mounted between the profiles and the plurality of frame portions and transverse to the rotor axis forming a sieve area for separating the grain from the crop mat. The separating grate is utilized in a combine harvester, preferably a self-propelled combine harvester. The sieve area is used to sift, separate or loosen grain, kernel or cereal from the crop with reduced fragmentation and clogging.
