DETAILED DESCRIPTION OF THE DRAWINGS The combine 11 shown in FIG.
1 includes a main frame 12 supported by a front pair of drive wheels 13, 14 driven by an engine 16 through a power train, not shown, and a pair of steerable rear wheels 17, 18.
An operator's cab 21 is mounted on the main frame 12 in front of a grain bin 22 and above a header 23.
Crop material severed by a header 23 is conveyed to an axial flow processor section 26 by conveying means including a conveyor 27.
The processor section 26 includes a stationary foraminous cage 28 and a coaxial rotor 29 disposed on a transverse horizontal axis 31.
Grain and other small particles of crop material passing through perforations or other radial openings in the cage 28 and a concave 32 fall by gravity to a pair of accelerator rolls 33, 34 which accelerate the grain and other small particles of crop material downwardly to a cleaning section 36 through an airstream directed rearwardly from a duct 37 connected to a transverse blower 38.
The cleaning section 36 includes a shoe assembly 41 suspended on the main frame 12 for a shaking movement by conventional means, not shown.
Referring to FIGS.
2, 3 and 4, the shaker shoe assembly 41 includes a horizontally disposed grain pan 42 at its front end for receiving grain accelerated downwardly by the accelerator rolls 33, 34.
Lightweight chaff and the like is blown rearwardly by the airstream emitted from the duct 37 out a rear opening 43.
The shaking action of the shoe assembly 41 causes grain to move rearwardly from the grain pan 42 to a chaffer 44 extending rearwardly from the grain pan.
Rearwardly inclined transverse baffles 46 retard rearward movement of the grain on the grain pan and longitudinal dividers 47 help to maintain a lateral distribution.
Longitudinally extending vertical dividers 48 are appropriately spaced laterally of one another on the chaffer 44 to help maintain a lateral distribution of material as it moves rearwardly on the chaffer 44.
It should be understood that the grain pan has a solid bottom whereas horizontal chaffer 44 and sieve 51 have vertical openings through which grain and other similarly sized particles may fall by gravity and pass to the clean grain auger 52
