Abstract
A progressive sieve assembly for an agricultural vehicle includes a sieve having a frame, a first subset of louvers that are pivotably connected to the frame, and a second subset of louvers that are also pivotably connected to the frame. The second subset of louvers are positioned downstream of the first subset of louvers as viewed in a direction of travel of grain across the sieve assembly. The first subset of louvers are configured to pivot independently of the second subset of louvers, and the second subset of louvers are configured to pivot independently of the first subset of louvers.
Claims15
A progressive sieve assembly for an agricultural vehicle, said progressive sieve assembly comprising:
- a sieve comprising a frame, a first subset of louvers that are pivotably connected to the frame, and a second subset of louvers that are also pivotably connected to the frame, wherein the second subset of louvers are positioned downstream of the first subset of louvers as viewed in a direction of travel of grain across the sieve assembly;
- wherein the first subset of louvers is configured to pivot independently of the second subset of louvers, and the second subset of louvers is configured to pivot independently of the first subset of louvers.
