  • Grain pan for combine harvester having horizontal pan area
    Patent number: 6238285
    Abstract: An agricultural harvesting machine having a threshing and separating mechanism for threshing and separating crop material; and cleaning mechanisms for cleaning the threshed and separated crop material. The cleaning mechanism comprising: a grain pan for receiving threshed and separated crop material and transporting the latter rearwardly; and an upper and lower sieves installed behind the grain pan and operable to receive the material from the grain pan and move it through and along. At least one portion of the grain pan is inclined in a sideways direction for sideways movement of the threshed and separated crop material while it is being transported rearwardly towards the sieve. This inclination spreads out the surplus of crop material supplied to one longitudinal section of the grain pan and delivers it in an even pattern to the front section of the upper sieve.
