Title: Combine harvester with an axial-flow threshing and separating unit

What is claimed is:

1. A combine harvester comprising a cutting table, an axial flow through threshing and separating unit which includes a threshing and separating cylinder, a counter-beater substantially in the form of a concave grill surrounding a lower part of a first portion said threshing separating cylinder, and a separator casing substantially in the form of a tubular grille surrounding a second portion of said threshing and separating cylinder, a support structure fixed to said cutting table and supporting said threshing and separating unit and with the axis of said threshing cylinder being disposed transversely with respect to the longitudinal axis of the compound harvester, a pair of spaced apart plates pivoted about a horizontal transverse axis to the front of said support structure, a shaft having the opposite end thereof carried by said plates with each end of said shaft being slidably disposed in a guide slot in said structure, a transverse feed cylinder mounted on said shaft upstream of said threshing and separating unit to feed a harvested crop through said unit and resilient suspension means for resiliently supporting said plates comprising a support secured to said support structure, a pair of rods articulated to said plates respectfully, and being slidably mounted in said support, an engagement member secured to each rod and resilient means interposed between each engagement member and said support.

2. A combine harvester as set forth in claim 1 further comprising a flap pivotally mounted on said support structure about a horizontal transverse axis for opening and closing an aperture in said cutting table below said feed cylinder, said flap being resiliently biased to a raised closed position and opening downwardly for the removal of foreign bodies.
