Material distribution means for concave of rotary combine

摘要

A mobile combine having longitudinally extending rotor and concave threshing and separating members and a grain pan beneath the threshing and separating members to receive threshed and semi-threshed crop material incident to transmitting said material to a sieve mechanism. In order to prevent uneven build up or deposit of said material in localized areas upon the grain pan, deflecting members are provided in several different embodiments or arrangements which are fixed to the threshing and/or the separating members, all having the common objective of deflecting material discharged from the threshing and separating areas of the grain pan which normally have low accumulation and thereby tend to cause substantially even distribution of said material upon the grain pan.
